Pillow packaging machine is a continuous packaging machine with very strong packaging capacity and suitable for a variety of specifications for food and non-food packaging. It can not only be used for the packaging of unbranded packaging materials, but also can be used for high-speed packaging with reel materials pre-printed with trademark patterns. In packaging production, due to the error between the positioning color marks printed on the packaging material, the stretching of the packaging material and the influence of mechanical transmission and other factors, the predetermined sealing and cutting position on the packaging material may deviate from the correct position, resulting in errors. In order to eliminate errors and achieve the purpose of correct sealing and cutting, packaging design must consider the problem of automatic positioning. The solution to this problem is mostly to complete the design of a continuous photoelectric automatic positioning system based on the positioning mark of the packaging material. The continuous photoelectric positioning system is divided into forward and retreat type, brake type and two-transmission system synchronization type according to the error compensation working mode.
purchase advice
1. First of all, you must determine which products you want to pack in the packaging machine you will buy. Some packaging machinery manufacturers have a wide variety of products. When buying a packaging machine, they hope that one piece of equipment can package all their varieties. In fact, the packaging effect of the machine is often better than that of the compatible machine. No more than 3-5 varieties can be packed by a packaging machine. In addition, products with a large difference in dimensions should be separated and packaged as much as possible.
2. High cost performance is the principle. At this stage, the quality of domestically produced packaging machines has been greatly improved, especially for pillow packaging machines. The export proportion has been a lot of imports, so the quality of imported machines can be purchased at the price of domestic machines. Buy what is right, not what is expensive.
3. Choose a packaging machine company with a long history as much as possible, and the quality is guaranteed. Choose models with mature technology and stable quality to make packaging faster and more stable, with low energy consumption, low manual work, and low waste rate. The packaging machine is a talent-consuming machine. If you buy a low-quality machine, the daily production of packaging film that is wasted over time in the future is not a small number.
4. If there is an on-site inspection, pay attention to the big aspects, but also to the small details. The details often determine the quality of the whole machine. Bring a sample test machine as much as possible.
5. In terms of after-sales service, "inside the circle" must have a good reputation. The after-sales service is timely and available on call, which is especially important for food processing companies. For example, moon cake companies only have a short two-month production period each year. If there is a problem in the production of the packaging machine that cannot be solved immediately, the loss can be imagined.
6. Packaging machines trusted by peers can be given priority.
7, as far as possible, choose simple operation and maintenance, complete accessories, fully automatic continuous feeding mechanism, which can improve packaging efficiency and reduce labor costs, which is suitable for the long-term development of the enterprise.
