Pillow type packaging machine is a large category of packaging equipment, it is the right-hand assistant of many manufacturers, it is the "changing room" of many products. There is no doubt about its packaging ability, but even so, many people's cognition of pillow packing machine is still relatively small. Why is it so popular? If you look down, you will understand.

Not only the packaging material with trademark can be used for packaging machine without logo. In the packaging production, due to the error between the positioning color standards printed on the packaging materials, the stretching and mechanical transmission of the packaging materials, the predetermined sealing parts of the packaging materials may deviate from the correct position, resulting in errors.

In order to eliminate the error and achieve the purpose of sealing and cutting correctly, automatic positioning should be considered in packaging design. Most of the problems are solved according to the positioning standard of packaging materials, and the design of continuous photoelectric automatic positioning system is completed. According to the error compensation method, the continuous photoelectric positioning system can be divided into the front and rear transmission systems, brake type and synchronous type.
