Pillow packaging machine is a continuous packaging machine with strong packaging capacity, suitable for different specifications of food and non-food packaging. It can be used not only for packaging unbranded packaging materials, but also for high-speed packaging of webs with pre-printed trademark patterns. In the manufacturing of packaging materials, due to errors, such as errors between the positioning color marks printed on the packaging materials, errors in the stretching and mechanical transmission of the packaging materials, the prescribed sealing and cutting positions of the packaging materials may deviate from the correct positions. This leads to errors.

In order to achieve the correct sealing and cutting purposes, packaging design must consider the issue of automatic positioning. In order to solve the problem of pillow packaging machine, the design of continuous photoelectric automatic positioning system was completed according to the positioning mark on the packaging material. According to the working mode of error compensation, the continuous photoelectric positioning system is divided into forward and reverse type, braking type and two kinds of transmission system synchronous type.

Pillow packaging machine: The packaged goods are transported horizontally to the entrance of the coil or film through the conveying mechanism (At this time, the coil or film is cylindrical, and the bag making machine and the packaged products enter the cylindrical packaging material.) Then it runs synchronously to perform the processes of heat sealing, air extraction (vacuum packaging) or inflation (expansion packaging) and cutting. Example: Packing foods such as bread, chocolate, biscuits, instant noodles, etc. in a pillow packaging machine. Yes, compared with horizontal or vertical packaging, pillow packaging is a relatively single item or block suitable for integrated items, such as strips, spheres and spherical. Double peripherals, batteries, and even packaged food (instant noodles), etc., are all pillow-type collective packaging.
