is a very strong packaging capacity, and can be suitable for a variety of specifications for food and non-food packaging continuous packaging machine.

It can not only be used for the packaging of non-trademark packaging materials, but also can be used for high-speed packaging with pre-printed trademark drum materials. In the packaging production, due to the error between the positioning color labels printed on the packaging materials, the influence of the stretching of the packaging materials, mechanical transmission and other factors, the predetermined sealing and cutting parts of the packaging materials may deviate from the correct position, resulting in error.

In order to eliminate the error and achieve the purpose of sealing and cutting correctly, the automatic positioning problem must be considered in the packaging design. The continuous optoelectronic positioning system can be divided into advance and retreat type, braking type and two transmission system synchronous type according to error compensation.
