Description

Position debugging system of sealing and cutting machine

Technical Field

The invention relates to the field of product packaging, in particular to a position debugging system of a sealing and cutting machine.

Background

In the film sealing and cutting packaging machine in the prior art, a folded film is conveyed to a film covering device through a film conveying device, the film covering device is provided with a first conveying device, the film covering device opens the film at the upper side and the lower side of the first conveying device to form a U shape, the first conveying device conveys a product to be packaged, and the film is driven to advance by a rear film conveying device; the film and the products are conveyed to a second conveying device at the back, a sealing and cutting mechanism arranged on the second conveying device performs L-shaped sealing and cutting on the film, the film is separated from the film conveying device after the sealing and cutting, and the film and the products are output by the second conveying device.

The current sealing and cutting machine has some problems needing to be optimized:

one, present seal and cut the function that the mechanism does not have the seal cut piece separation distance about debugging, cut the completion back once promptly, seal cut piece can separate to the maximum distance that actuating mechanism limited from top to bottom, when the encapsulation that will pack is cut the product that the specification is less, it is in fact sealed cut piece from top to bottom to be greater than the height of product can, it closes to seal to cut like this and separates the required time shortest after sealing and cutting the completion, can effectively improve the seal efficiency of cutting the product, when the product is carried in batches and is sealed and cut, this efficiency will be enlarged, make can seal more in unit time and cut the packing product, improve production efficiency, bring economic benefits for the user.

The first conveying device comprises blocking pieces on two sides to limit products according to different product widths, and when products with different specifications are conveyed, the width between the blocking pieces on the two sides needs to be adjusted.
