Paper bag machine sealing and cutting system

Release time:


paper bag machine paper bag fixed-length sealing and cutting. This positioning system is a fixed-length positioning system, which only requests the speed of sealing and cutting movement to match the bag feeding speed to reach the request of fixed-length sealing and cutting.

printing bag positioning system, printing bag positioning system is the positioning marking, and the position of each sealing and cutting request must fall at the designated identification position.

is bound to encounter a problem when carrying out various sealing and cutting missions. That is, the bag length of each mission request may be changed, which will inevitably affect the initial value of bag length preset in our system.

Because the interval S between the photoelectric eye and the sealing and cutting of the paper bag mark is a fixed value, the bag length is changed, which will inevitably affect the relationship between the bag feeding speed and the sealing and cutting speed. Therefore, in order to realize the active positioning of processing, it is necessary to make a certain function adjustment between the bag length and the interval S. But this is only useful for sealing and cutting printed bags, and it is meaningless when sealing and cutting paper bags.

In the packaging production profession, the composite thin bags used as packaging bags can be divided into two types: one is a paper bag, and the other is a printing bag (color bag). The color bag is printed with other marks that can be used for photoelectric signal inspection sensor identification. The

active positioning system of the sealing and cutting machine actively checks the frequency of the sealing and cutting machine controlled by the main motor through the photoelectric signal sensor, and then converts it into a pulse number and compares it with the pulse number checked by another photoelectric signal sensor, and adjusts the frequency of the feeding stepping motor to change its feeding speed so as to adapt it to the sealing and cutting movement of the main motor.
