Bag cutting machine

Abstract

The invention provides a bag cutting machine. The bag cutting machine comprises a rack and a bag feeding device, a bag cutting device and a bag collecting device, wherein the bag feeding device, the bag cutting device and the bag collecting device are sequentially arranged on the rack in the feeding direction of a bottomless plastic film, the bag collecting device comprises a bag pressing module and a bag arranging module, the bag pressing module drives a bag pressing frame to reciprocate up and down through a pair of first linear driving mechanisms, a bag pressing plate is driven to move awayfrom or close to a supporting plate to realize the bag pressing of square plastic bag bodies; and the bag arranging module comprises a head carding mechanism, the head carding mechanism is characterized in that a cam assembly is driven by a pair of first driving motors to rotate through a mechanical transmission mechanism, and the heads of the square plastic bag bodies which are cut off are carded down by utilizing the characteristic of intermittent movement of the cam assembly. According to the bag cutting machine, the cut square plastic bag bodies are carded in time while the bag cutting isachieved, the quality of the cut bag is improved, the defective rate is reduced, and then the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of bag cutting equipment, in particular to a bag cutting machine for plastic film bag cutting. Background technique [0002] The bag cutting machine is used to cut the rolled bottomless plastic film into a square plastic bag with a predetermined size. When cutting the bag, one side of the bottomless plastic film will be cut off or sealed. In order to improve the processing efficiency, the cut The square plastic bags are stacked together to form a pile of plastic bags, and then the stack of plastic tapes stacked to a predetermined number is taken away and entered into the next process to punch out the bag mouth or the handle mouth, because the bottomless plastic film is sent into the cutting bag by intermittent driving mechanism Bags are cut inside the machine, and the bottomless plastic film is light in weight. After floating in, it is affected by air resistance and completely relies on its own gravity to sl...
