Transverse sheet supplementing device of bag making machine

Abstract

The invention discloses a transverse sheet supplementing device of a bag making machine. The device comprises a front wall plate and a movable seat, and a traction lower rubber roller and a traction upper pressing roller are arranged between side plates; an upper cutter is arranged between the two side plates, wherein a lower cutter is arranged below the upper cutter; an upper sealing module is installed on the bottom surface of an upper mounting rod, and a lower sealing module is installed on a lower mounting rod; one short rod is provided with an adjusting screw, wherein one end of the adjusting screw is provided with a first adjusting hand wheel; one end of an adjusting hand wheel shaft is fixedly provided with a second adjusting hand wheel, wherein a gear is fixedly installed on the adjusting hand wheel shaft. According to the sheet supplementing device, adjusting can be carried out in the front, rear and transverse directions, so that a feeding position of a main film material canbe accurately reached; and adjusting is flexible, the traction upper pressing roller can be conveniently controlled, and meanwhile adjusting is convenient, and heat sealing effects are good; and in addition, by adjusting the front and rear positions of the lower cutter, the knife edge of the lower cutter is aligned with the knife edge of the upper cutter, and therefore cutting effects of sheet supplementing materials are guaranteed.

Description

technical field [0001] The invention relates to the technical field of bag making, in particular to a transverse patching device of a bag making machine. Background technique [0002] As people's pursuit of quality of life is getting higher and higher, people's requirements for packaging supplies that are indispensable in life are also getting higher and higher. The pulling strength and safe use performance of plastic packaging bags are also very important parts, so It is necessary to patch the hand-held part of the packaging bag and other weak parts through the patch device to improve the tensile strength. The patch device drives the patch film material to the position of the main film material, and heats it through the sealing module; [0003] The patent document (CN203267286U) discloses an internal patching device of a packaging bag making machine. The patching device cannot move laterally, nor can it adjust the position of the sealing template. When working, it cannot be...

AI Technical Summary

Problems solved by technology

[0005] The cutter cylinder drives the cutter mounting seat to descend, thereby driving the upper cutter to descend, and the lower cutter is arranged horizontally below the upper cutter, and the two cooperate with each other so that the patch film material is quickly cut off, which solves the problem of the existing patch device The cutting effect is poor, and the main film material is pulled when cutting the patch film material, resulting in poor heat sealing effect between the main film material and the patch film material;
