A material feeding device for the first roll of a packaging machine

Abstract

The invention belongs to the field of packaging machine auxiliary devices, and particularly discloses a first-roll material penetration device for a packaging machine. The first-roll material penetration device comprises an overall rack, a feeding unit, an unrolling unit and a conveying penetration unit, wherein the feeding unit, the unrolling unit and the conveying penetration unit are sequentially arranged on the overall rack from left to right; the conveying penetration unit comprises a conveying assembly, a material penetration assembly and a driving assembly, the conveying assembly comprises a deflection idler roller and a floating roller which are horizontally arranged, the deflection idler roller is installed on the overall rack, the two ends of the deflection idler roller are hinged to the overall rack through side end supporting plates, and chain wheels are installed at the two ends of the deflection idler roller and the two ends of the floating roller; the material penetration assembly comprises a material penetration driving piece and a plurality of material penetration rollers, the two ends of each material penetration roller are provided with chain wheels, the chains wheels, located on the same side, of the deflection idler roller, the floating roller and the material penetration rollers are matched with a chain, and the two chains are provided with a flexible connecting plate; and the driving assembly is arranged between the two material penetration rollers. By means of the first-roll material penetration device, automatic and efficient material penetration ofroll materials can be achieved, the beneficial effects of being simple in structure, convenient to operate and the like are achieved, and the first-roll material penetration device is suitable for material penetration of a woven bag in the packaging machine.

Description

technical field [0001] The invention belongs to the field of packaging machine attachments, and more specifically relates to a first roll material threading device of a packaging machine. Background technique [0002] In the field of fully automatic packaging production of solid materials, powders, etc., the unwinding and cutting process of woven bags involves deflection rollers, tensioning components and deviation correction components, making the path of woven bags complicated during the material feeding process, and different types of The advanced equipment has no rules to follow, so the process of threading the packaging bag has always been a very troublesome problem in the industry. [0003] Patent 200410043875.6 discloses a typical bag forming automatic packaging machine. The bag forming packaging machines are all designed with complex idler rollers and floating rollers, so that the material needs to pass through the complex interlaced idler rollers and floating roller...

[0002] In the field of fully automatic packaging production of solid materials, powders, etc., the unwinding and cutting process of woven bags involves deflection rollers, tensioning components and deviation correction components, making the path of woven bags complicated during the material feeding process, and different types of The equipment has no rules to follow, so the process of threading the packaging bag has always been a very troublesome problem in the industry

[0003] Patent 200410043875.6 discloses a typical bag forming automatic packaging machine. The bag forming packaging machines are all designed with complex idler rollers and floating rollers, so that the material needs to pass through the complex interlaced idler rollers and floating rollers in the first feeding, which requires The two workers cooperate with each other, the labor intensity is high, and the first complicated automatic material threading problem has not been solved

Patent US20130036710A1 discloses a method for producing and filling a packaging device in which a flat tubular film material comprising two parallel hose edges is unrolled from a roll in the direction of the main axis of symmetry of the hose, the main buffer The rollers and deflection rollers are arranged along the vertical direction, and the structure is very compact, which shortens the distance of the entire material feeding, but it still needs to manually perform complex feeding actions in a small space, which does not solve the essential problem of material feeding difficulties

Patent CN201611101030.7 discloses a cold-cutting and hot-melting multi-functional all-in-one machine, which is characterized in that the surface of the frame is the feeding channel of the woven bag, and the cutting parts, sewing parts, curling heat The melting parts, compacting parts, and power drives are installed under the frame. The rollers and rubber rollers of this equipment are more complicated, and there is still no mention of how to complete the material feeding action simply and effectively.
