Everyone can know from usual attention that many of the products we buy are packaged in paper. Compared with paper bags, plastic bags are more harmful to the environment, so now we call on everyone to use paper bags. However, my country's paper bag machine technology is not mature enough, and many process technologies rely on other countries. This is a phenomenon that needs to be changed urgently.
Facing the large demand, the traditional paper bag machine has become more and more inadequate, with electronic control, photoelectric control, pneumatic control and other control forms. However, with the increasing productivity and random changes in packaging parameters, these control systems have become increasingly difficult to meet the development of the new situation.
At this time, a new technology, the mechatronics technology, came into being, which completely changed the face of the long paper bag machine and made it appear in front of the world with a brand-new attitude. The development direction of mechatronics technology innovation. In the current era of rapid advancement in science and technology, the emergence of various new technologies, new processes, new materials, and new equipment is no longer just the development of a certain discipline, but various related disciplines. , The result of the mutual penetration and complementarity of a variety of advanced technologies, so our paper bag machine now has many modern mechanical characteristics, such as more intelligent and sophisticated.
Mechatronics technology is such a new technology, which is a comprehensive technology established on the basis of information theory, cybernetics and system theory. Its essence is to use process control principles to organically combine related technologies such as machinery, electronics, information, and detection from a system perspective to achieve overall optimization. Specifically, it is the introduction of microcomputer technology into packaging machinery.
In the promotion and use of technology, the face of the paper bag machine has been fundamentally changed. In this packaging machine, the microcomputer is its brain, replacing the conventional control system. The mechanical structure is its main body and torso. Various instruments, meters, and sensors are its senses. They feel the changes of various packaging parameters and feed them back to the brain (computer). Various actuators are its hands and feet to complete Actions necessary for packaging operations. Such equipment can better serve our lives, meet people's demand for mass use, and truly promote paper bags.
Paper bag machines are mainly used to produce paper packaging bags and are widely used in many industries. When the paper bag machine is running, we need to pay attention to many things. In short, it is enough to ensure that the products produced meet the standards. If the exhaust is not clean during the operation of the paper bag machine, it needs to be compacted immediately.
1. Keep the unloading and dragging materials stable. The unloading swing roller should not be too high or too low, and the dragging should not be too loose or too tight. These conditions will cause the material to produce radial jitter during operation, leading to inaccurate tracking of the photoelectric eye of the front and rear and discharging color codes, and the bag length will be incorrect. It will also cause the bag length to be stretched. Adjust the air pressure of the discharge pressure roller.
2. The temperature setting is suitable. If the temperature is too high, the product will wrinkle and affect the photoelectric tracking, which may increase the photoelectric sensitivity when the bag length is different. After the temperature stabilizes, reduce the sensitivity to prevent tracking failure. Choose the right temperature according to different products (material properties, thickness and packaged products). The pressure gap of the hot knife should generally be about 1.5 mm, especially when the hot knife gap is required to be too large during high-speed operation, otherwise the stability of the dragging material will be affected. If the sealing width is too large and the gap cannot be reduced, the only solution is to reduce the feed ratio in the computer or speed up the drawing speed. This is an effective method when the bag length is long and the bag length does not reach the set bag length when the double delivery is not used.
3. Adjust the product to run in the middle of the pressure roller. Adjust the balance of the left and right gaps of the pressure roller. Remove the remaining garbage, dirt and edge material on the rubber roller in time to ensure that the left and right gaps of the entire pressure roller are consistent. In this way, it can avoid the situation that the dragging material swings unsteadily due to the improper adjustment of the rubber roller air pressure and the long-term unbalanced wear of the rubber roller.
4. The material produces abnormal noise during operation. First, the problem of the mechanical part needs to be eliminated. Then you need to observe whether the noise generated after acceleration will appear in: the ironing knife is too low or the ironing cloth is rolled up too loose There is plastic The mud pulling speed is set too low. The tension between the two rubber rollers is too small. The unwinding tension is too large. The improper setting of the pulling motor speed will cause the motor load and the speed of the main machine to not match the phenomenon. At this moment, the motor load will increase and the inertia during start and stop will cause noise.
5. Keep the height of the hot knife in the same straight line when the material passes on the same horizontal line. Balance the pressure of the bottom seal hot knife and the height of the bottom hot knife. Keep the pressure of multiple hot knives on both sides. If the heights of multiple lower ironing knives are equal and the side seals remain the same, the different heights will cause the material to swing from side to side and the width of the sealing and welding will have a great impact on the flatness of the bag.
6. The exhaust of the material during operation is not clean. The residual air in the material will cause the overall deformation of the bag and affect the normal operation of the material. There will be a certain noise. It is necessary to properly compress the relevant layering. The side seal ironing cloth should not cause additional resistance due to adhesion between the material and the ironing knife.
Special attention is that the paper bag machine must be in accordance with the requirements of the product customer as the production standard of the product. The customer puts forward reasonable suggestions for the product quality requirements of the product. The adjustment must first be part of the local computer, bottom seal, side seal, and discharge part; Knife pressure roller, unwinding tension photoelectric sensitivity.
All the paper bags used in our lives are produced by paper bag machines. The production process of paper bag machines is more complicated, but it is a fully automated machine, so it does not require manpower. However, there are many details that the staff need to pay attention to during the production process of the paper bag machine, so as to ensure the high quality of the paper bags produced.
So what are the problems in the development of my country's paper bag machine industry? The main problem in the development of my country's paper bag machine industry is the fragmented product structure. From the perspective of product structure, my country's paper bag machine has a small number of varieties, lacks high precision and large products, and cannot meet market demand. The product quality gap is manifested in poor product performance stability and reliability, unsightly appearance, rough surface treatment, poor quality of many components, short life span, and low reliability, which affects the overall product quality; from the perspective of enterprise conditions, domestic paper bag machines The industry lacks leading companies, and there are not many companies with large-scale production and high-grade products; from the perspective of product development, my country is basically still in the imitation stage, with weak self-development capabilities, and scientific research funding only accounts for 1% of sales, while foreign countries are as high as 8%. —10%. Generally speaking, compared with international advanced products, my country's paper bag machine is at a disadvantage in the competition of product development, performance, quality, reliability, and service.
Now we are going to talk about the reasons for these problems. The first is the lack of macro-control. Because the paper bag machine company has a low starting point, "innate insufficiency" and cross-sectoral, there are problems in overall planning and macro guidance. It is difficult to invest and develop new products. Aspects are often rushed, and there is a disorderly competition of low-level repetition. There is also a lack of capital investment, which is also a common feature of the machinery industry. It is difficult to attract a large amount of capital investment, and it is difficult to carry out a large amount of technological transformation. Due to insufficient funds, the company's investment in research and development accounted for less than 1% of the average sales, and it was impossible to produce one generation, one development, and one research. Due to the lack of technical reserves, the inability to introduce technology and digestion and absorption has resulted in fewer new products and lack of competitiveness.
In addition, the lack of professional and technical personnel is also a problem. Because the paper bag machine industry is not profitable and it is difficult to attract excellent technical personnel, the talent team is uneven, independent product development and innovation capabilities are weak, and even the ability to absorb similar foreign products is weak. , Resulting in a consistent system for many years.
Due to the fragmented situation in my country's paper bag machine industry, the structure of the industry is facing adjustment. From the above analysis of several factors that caused this situation, we can see that the entire paper bag machine industry has the following risks in credit investment: the paper bag machine industry has serious repetitive production problems, and the low entry barrier and insufficient control measures are caused by The cause of this problem. For the paper bag machine industry, the future may face national macro-control, and new projects will be subject to certain restrictions. It is believed that with my country's protection of intellectual property rights and the continuous improvement of people's requirements for products, my country's paper bag machine equipment industry will usher in a period of rapid development.
Compared with manual packaging, the working efficiency of the paper bag machine is many times higher, and it can also ensure that the packaging meets the standard. For example, inflatable packaging and vacuum packaging cannot be completed manually. At this time, the paper bag machine plays a very important role and can also completely unify the packaging specifications of the goods.
Secondly, the paper bag machine can effectively ensure the quality of packaging
In this use, we should see that the mechanical packaging of the paper bag machine can be based on the requirements of the packaged items. Therefore, we should see that in this use, you can obtain the packaging with the same specifications according to the required shape and size, and you can see it. When it arrives, manual packaging is not guaranteed. Secondly, this is particularly important for export commodities. Only mechanical packaging. At this time, we suggest that everyone can achieve packaging standardization, followed by product standardization, which meets the requirements of collective packaging.
Finally, the paper bag machine can achieve operations that cannot be achieved by manual packaging
We will see that there are some packaging operations, because it can make our use more convenient. At this time, it is necessary to see that vacuum packaging, inflatable packaging, skin packaging, isobaric filling, etc., which cannot be achieved by manual packaging, can only be achieved with paper bag machine packaging.
