Cutting device of a bag making machine

Abstract

The invention relates to the field of plastic bag manufacturing, in particular to a cutting device of a bag making machine. It includes: two cutting mechanisms; the cutting mechanism includes: a receiving seat, a cylinder, a motor one, a motor two, a gear one, and a gear two; the above-mentioned receiving seat has a plurality of spray holes at intervals; the side of the cylinder has Ferrule; there is rack one on the ferrule, rack one meshes with gear one, and gear one is installed on motor one; there is a piston inside the cylinder, and the piston rod is connected to rack two; rack two meshes with gear two, and gear one The second is installed on the motor two; the side wall of the above-mentioned cylinder has an air inlet; the bottom surface of the above-mentioned cylinder has an injection port; the present invention utilizes compressed gas to complete the cutting of the plastic bag, which is very convenient to make and avoids the friction between the piston and the cylinder. The receiving seat will not be damaged during collision and cutting, which avoids damage to the equipment and prolongs the service life of the equipment.

Description

technical field [0001] The invention relates to the field of plastic bag manufacturing, in particular to a cutting device of a bag making machine. Background technique [0002] Plastic bags are commonly used packages in people's daily life. There are many types of plastic bags, one of which has a curved shape on both sides and a cutout of multiple micro-connected parts. [0003] The existing manufacturing method is to supply intermittently along the length direction of the film, and then when it stops, the knife moving part drives the knife to pass through the film from top to bottom and abut against the lower receiving seat to complete the cutting, but there are also the following problems question: [0004] 1. In order to cut out the curved shape on both sides, it is usually necessary to make the shape of the knife edge into a curved shape, which is very inconvenient in the production and later grinding and maintenance of curved knives; [0005] 2. Since the cutting tool...
