The working principle of pillow packaging machine
Pillow packaging machine is a continuous packaging machine with very strong packaging capability and suitable for a variety of specifications for food and non-food packaging. The pillow packaging machine can not only be used for packaging of non-labeled packaging materials, but also can be used for high-speed packaging of roll materials with pre-printed trademark patterns. In packaging production, due to the errors between the positioning color marks printed on the packaging materials, the stretching of the packaging materials and the influence of mechanical transmission and other factors, the predetermined sealing and cutting positions on the packaging materials 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 continuous photoelectric automatic positioning system design 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.
