How to Choose Carton Equipment in Newly Opened Carton Factory

What factors should we consider when opening a small carton factory? How to choose? How to take into account the cost-effectiveness of investment and not waste costs? I. Production Capacity DemandProduction capacity is the output of a factory after its commissioning, which can be specific to each capacity. For example, if the production capacity is less than 10000, it is only necessary to select some semi-automatic carton machinery and equipment. If the production capacity is between 30,000 and 50,000, we need to choose these highly automated carton machine and equipment.II. Investment Capability It is the amount of investment of the former cardboard box factory. The liquidity of the cardboard box factory is very important, especially when the cardboard box is processed from the cardboard. Generally speaking, the purchase of carton machinery accounts for 35% to 45% of the liquidity. The specific speed can be adjusted according to the speed of loan return. III. Industry Classification and Characteristics of Orders The selection of carton equipment varies with the industry classification and characteristics of the order. For example, some small carton factories with monthly production capacity between 10W and 50W have limited investment in the equipment of carton factories, so the selection of carton equipment is particularly important. The order of carton factory is simple in structure, large in quantity and stable in carton factory. It is better to choose one machine (printing slotting die-cutting machine). If the order is scattered, we can choose some separate independent machines (carton printing machine, paper splitter, nail box machine, slotting angle cutting machine). Some carton friends think that second-hand carton equipment is cheap. They think that the previous investment in carton machinery and equipment is not very important, resulting in quality problems at both ends of the carton equipment bought in the later period of three days. After that, they have to stop the machine for maintenance. They spend a lot of time on the maintenance of carton equipment.

Pay Attention to the Problems in Choosing Carton Packaging Machinery for Carton Enterprises

The fierce competition in carton packaging industry makes the profits of carton enterprises less and less. Increasing production efficiency and reducing wastage and waste in the production process are very worthy of study for carton enterprises. Improving the automation of equipment is an effective way to improve production efficiency. Therefore, enterprises are willing to invest heavily in introducing advanced production lines and purchasing new equipment. But we can see that in many enterprises, the utilization rate of equipment is very low, and the newly purchased equipment often can not meet the requirements of technology or production technology, and even some equipment is idle, causing huge waste to the economic production of enterprises. On how to choose and purchase carton equipment to avoid the above situation, we talk about our own views, hope to be able to exchange and discuss with colleagues.Matters needing attention before purchasing1. Before purchasing carton equipment, relevant departments of enterprises should communicate with each other and reach consensus.Enterprises should jointly determine the basic types and specifications of equipment according to their actual production needs and the configuration of the original production equipment, determine the procurement department and related personnel of equipment, equipment installation, commissioning, acceptance and acceptance department and related personnel and responsibilities. The equipment purchasing department collects and collates the information of equipment manufacturers, main structure characteristics, technical parameters, function introduction of each part of equipment, price and so on, according to the basic conditions of the determined models and specifications. Detailed and conscientious preparation of equipment selection survey report, the various aspects of equipment manufacturers horizontal and vertical comparison, to select the final manufacturer.2. Pay attention to the technical evaluation of equipment.The first step in selecting and evaluating equipment is often to conduct a careful use or technical inspection to determine whether the equipment is technically feasible. In evaluating the technical specifications of an equipment, the following factors should be carefully examined:1. Production capacity. When choosing an equipment, its production capacity should be able to meet the requirements of the current production situation and be competent in the foreseeable future. Excessive or inadequate use of equipment production capacity is not advisable. It is no doubt unwise to buy an equipment that will soon fail to meet the requirements of the production process. Similarly, it is an unforgivable loss to purchase an equipment with a high production capacity that has never been needed, especially when the price of the equipment is more expensive. Therefore, when choosing equipment, we should objectively evaluate the performance, production efficiency and production capacity of the equipment to be purchased from the specific production technology level and production development prospects, so that the production capacity of the equipment can be fully and reasonably used.2. Reliability. The so-called reliability refers to the enduring ability of the equipment to complete the prescribed functions under the prescribed conditions and within the prescribed time. Nobody wants to buy an old malfunctioning equipment, because it will not only cause losses, but also delay the delivery time, especially in today's increasingly shorter product delivery time and fiercer market competition. Therefore, the purchase of a safe and reliable equipment is an important factor for inspection.3. Maintainability. The so-called maintainability means that the equipment is easy to maintain. Although there are many equipment that need not be repaired now, for the vast majority of the equipment, failure is always unavoidable. Therefore, when choosing equipment, maintainability should be an important evaluation factor. When other factors are basically the same, no doubt the equipment with structure, easy inspection, maintenance and repair should be selected.4. Universality. Where possible, the newly purchased equipment and the existing equipment of the enterprise should be mutually versatile in terms of spare parts supply, maintenance and operation, in order to save personnel training, personnel training costs and auxiliary equipment procurement costs.5. Safety. Although there are few unsafe equipment sold in today's market, the safety of equipment is very important to the production of enterprises and the safety of personnel, so we should carefully evaluate the selection of carton equipment.6. Complementarity. In today's increasingly complex and sophisticated equipment, many equipment can only play a full role with the assistance of complete auxiliary equipment. Therefore, when choosing the main equipment, the matching situation and utilization rate of auxiliary equipment are often taken into account as the decisive factor. Especially for the increasingly widely used CNC equipment, if there is no matching "auxiliary equipment", the role of these equipment is very difficult to play.7. Operational. The increasing complexity and precision of equipment does not mean that the operation is becoming more and more complex. Excessively complex equipment will increase the training cost and cause operator fatigue and error, so simple equipment should be selected.8. Easy to install. This is often overlooked. Before purchasing the equipment, the installation site of the equipment should be inspected. For some large-scale equipment, transport routes should be inspected in order to select suitable equipment which is easy to transport and install.9. Environmental protection. The environmental protection of equipment includes two meanings: one is to reduce the loss of raw materials, the other is to save energy consumption. Environmental protection is not only the need to reduce product costs, but also an important chip for enterprises to participate in international competition.

What carton machinery and equipment are needed to establish the carton factory

There are a lot of equipment used to process the carton, according to different types of different division of labor, the production and processing efficiency is higher. What carton packaging machinery and equipment should be required to build the new carton? Here to briefly introduce some.Paper cutting machine: there are ordinary paper indentation machine and thin knife paper cutting machine two, the difference is that the former economic flexibility is high, manual operation. The microcomputer machine, electric and manual control machine, paper cutting flat without explosive force, high accuracy, general with leveling device, after the formation of the indentation, easy folding, is not easy to burst pressure or pressure strengthening core paper and so on.Printing ink: is divided into monochrome, two-color, three, four or six, but the difference is more group printing drum. Due to the fine print, clear lines, rich color, low cost, environmental protection and other advantages, the ink ink printing machine has been widely used.Corner cutting and groove cutting machine: This is the cardboard carton of key equipment, cutting angle is the carton adhesive is produced from a cardboard, slot is according to the size of production from a single flat cardboard separation length and width of the distance, from open space out, convenient in carton sealing and folding machine can be divided into a manual, semi-automatic and fully automatic.Nail box machine: common carton in the side has a copper or silver double nail or single screw, arranged in a certain distance and orderly, staples like nails, that is nail box machine to play, the purpose is to put the nail carton into a square.Visco box machine: a mechanical device is gradually became popular a kind of equipment, mainly Europe and the United States for the metals require strict, high environmental protection requirements, some foreign trade export cartons are the glue bonding, at present this kind of equipment have semi automatic and automatic type, suitable for carton used in single pit and pit and equipment adjust speed, get started quickly, instead of manual stick box to improve the effectiveness of such advantages.Now the mechanical equipment is needed to pass through the reasonable use to make the carton production more efficient, with the rapid development of mechanical, more machinery and equipment is beginning to emerge, which makes the machinery industry has also been more attention and rapid development.

Goodbye to warping

Like so many things today, corrugated board is judged by its appearance, too. In addition being durable, corrugated boxes need to look good in order to sell their contents. Valmet’s innovative quality management concept for corrugators dives deep into the production process.Demand for corrugated boxes is growing in line with the popularity of online shopping. On the other hand, supermarkets and retailers are increasingly using shelf-ready packaging and thus want boxes to look attractive.At the same time, things are changing in corrugated board production processes. Boxes are being made out of lighter-weight board, and their construction is more complicated. Delivery times to customers are shorter, production batches are smaller, and there are more grade changes. Cost pressures are immense.All the above-mentioned trends and challenges increase the need to raise the level of automation in corrugated board production.“When it comes to quality management, corrugators are about 30 years behind paper machines. They feature a high amount of manual control and no online measurements at all. There is a definite need for a quality management system similar to one used in paper machines,” says Mikko Talonen, Business Manager, Converting Solutions, Valmet.Valmet has more than 50 years’ experience from thousands of quality control system deliveries for pulp, paper, board and tissue production. The new Valmet IQ for Corrugators is based on this strong know-how.“We are now utilizing our automation, measurement and quality control know-how in converting. Since corrugators are smaller, simpler and narrower than paper machines, we have modified our existing products as well as developed new compact and cost-efficient measuring techniques especially for corrugated board production,” Talonen continues.Moisture management in the lead roleTraditionally, the quality of corrugated board has been controlled by measuring sheet temperature and adjusting the process accordingly. However, this is challenging as there can be up to over 10 drying and re-wetting cycles in the process, not to mention speed and raw material variations.“By monitoring the moisture trend and stabilizing moisture variation with a multivariable control system, it is possible to significantly improve both product quality and plant productivity. Moisture measurement has been critical in paper machines for a long time, and its importance does not lessen in converting”, Talonen emphasizes.By controlling the moisture content and temperature of corrugated board online, it is possible to ensure bonding and avoid both the washboard effect and cracking. Furthermore, the QCS helps eliminate warping caused by moisture. Comprehensive moisture management improves plant efficiency and productivity, too.“In converting, warped board does not run smoothly on an automatic conveyor after the corrugator. Instead it needs to be manually fed which is slow and presents a safety risk. Additionally, warping causes waste both during corrugated board production and later during storage before converting,” Talonen continues.Multipoint moisture measurement in several locationsThe most important element in the new control concept is the compact and cost-efficient Valmet IQ Multipoint Moisture Measurement.“The measurement is based on infrared (IR) technology. IR radiation produced with a halogen lamp is led onto the moving sheet with optical fibers through sensor heads. Moisture is measured by analyzing the reflection spectrum with a detector unit in a field cabinet. It is possible to measure the moisture content in nine positions with one device. Sensor heads can thus be installed in each drying and re-wetting cycle of the process. This measurement enables moisture control of corrugated board in a totally unprecedented way,” explains Mikko Viitam?ki, Product Manager, Valmet.The compact sensor head fits into the tight confines of the corrugator and contains no electrical parts. Its structure has been designed for harsh environments. Purge-air ensures that no dust or water collects inside the sensor head or on the optical surfaces.The effect of a speed change on the moisture content measured with Valmet IQ Multipoint Moisture Measurement in various process stages and on warping measured with Valmet IQ Warp on the conveyor.Goodbye to warpingThe camera-based Valmet IQ Warp Measurement  measures the sheet profile and warping on the stacker with a laser. The data is transferred to the control system to make calculations and analyses.“From there the data proceeds to the QCS where set-point changes for moisturizers or the wrap arms of heating cylinders are made if necessary. The measurement offers the fastest possible feedback to the corrugator,” Viitam?ki continues.The line laser makes it possible to measure the entire sheet profile with one measurement contrary to a point measurement.Controls optimize qualityAn integral part in controlling the quality of corrugated board during production is made up by Valmet’s advanced control algorithms. They are the tool to optimize the end product quality right from the very beginning of the process. The multipredictive control utilizes all online measurements to eliminate warping, improve bonding and avoid the washboard effect.
