Description

Bag making machine

Technical Field

The invention relates to the technical field of bag making machines, in particular to a bag making machine.

Background

The bag making machine is one kind of machine for making plastic bags and other material bags in different sizes and thickness. In general, plastic packaging bags are used as main products. The bag making machine is a dual-purpose machine for point-breaking and continuous rolling flat bags and point-breaking and continuous rolling vest bags. The step-by-step fixed length system is controlled by a computer, so that the sealing and cutting dimensional error is small. The device eye tracking allows the pattern position of the printed pocket to be accurate. The computer numerical control can be selected to adjust the length of the bag, and the machine automatically stops when the printing bag is in trouble and gives out warning sound.

For example, the Chinese patent with the publication number of CN105774045B provides a multi-station full-automatic processing integrated machine for woven bags, which comprises an outer bag cutting machine, an inner film making machine and an inner film pulling machine, wherein one outer bag cutting machine is arranged to correspond to a plurality of inner film making machines, and the original one-way one-to-one bag feeding mode is changed into a left-side and right-side or same-side bag feeding mode. And a printer is further arranged on the outer bag cutting machine to realize the integration of printing, cutting, sleeving and sewing, so that the independent printing is improved into an integrated printing mode. But the material can not be fine when conveying the elasticity of regulation material, leads to the material to be excessively stretched to and when the material takes place the skew, the device can't correct the material position, leads to subsequent processes such as cutting to produce the deviation.
