Packing bag tearing line punching apparatus

Abstract

The invention discloses a packing bag tearing line punching apparatus, comprising a conveyor belt apparatus and a rack. A sliding rod and a knife rest are disposed on the rack upwards, a compression rod and a cylinder are sequentially connected to the tool knife upwards, a cutter bar and a cutter head are sequentially connected to a lower surface of the knife rest downwards; a knife seat for accommodating the cutter head is disposed directly below the cutter head, the upper surface of the knife seat is flush with the upper surface of the conveyor belt on the conveyor belt apparatus; a photoelectric detecting switch is disposed on both sides of the conveyor belt apparatus, the photoelectric detecting switch is located on the feeding direction side of the cutter head, pressure rollers are arranged on both sides of the conveyor belt apparatus, and the pressure rollers are fixed to the rack by a length-adjustable and height-adjustable connecting rod. According to the packing bag tearing line punching apparatus, the height-adjustable and spacing-adjustable pressure rollers are arranged to adapt to the width and thickness of the packing bag, the pressure rollers flattens the packing bag, prevents the packing bag from warping, the tearing lines are guaranteed to be uniform and parallel, and the tearing lines of the packing bags of various specifications can be punched.

Description

technical field [0001] The invention belongs to the technical field of packaging processing, and in particular relates to a tearing line punching device for packaging bags. Background technique [0002] There is an easy-to-tear part on almost all packaging bags, usually called the tear line. Usually, manufacturers will produce packaging bags of various specifications. After other processes of the packaging bags are completed, the last process is to punch the tear line, but Due to the different specifications of the packaging and the large difference in width and thickness, it is impossible to accurately punch and cut the tear line. Contents of the invention [0003] Purpose of the invention: Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a packaging bag tearing line punching device capable of punching and cutting the tearing line of packaging bags of different widths and thicknesses. [0004] Technical solution: In order to...
