Bag supporting device for sleeve type inner-and-outer-bag material packaging full-automatic line

Abstract

The invention relates to the technical field of packaging machines, and specifically discloses a bag supporting device for a sleeve type inner-and-outer-bag material packaging full-automatic line. Thebag supporting device comprises a tubular charging hopper, a bag supporting mechanism, a bag inserting mechanism, a stress protection mechanism, a bag clamping mechanism, a first limiter and a secondlimiter. By means of the bag supporting device, the positions of two tensioning surfaces after a sleeve bag is tensioned are detected through the limiters, then the bag supporting range of the bag supporting device is further determined, and the failure rate of bag supporting is reduced; the bag supporting mechanism is simple in structure and avoids the phenomenon that a guide rod and a guide sleeve seat are blocked and locked in the prior art; the bag supporting mechanism also has certain swing amount, the sleeve bag can be better protected, and limiting of the limiters is more accurate; andthe stress protection mechanism can transfer extruding force of the sleeve bag during bag supporting so that the effect of protecting an actuating element is achieved.

Description

Technical field [0001] The invention belongs to the technical field of packaging machinery, and particularly relates to a bag supporting device of a fully automatic line for packaging materials in a packaged inner and outer bag. Background technique [0002] The inner and outer bags of the packaged inner and outer bags (suitable bags for short) are made of plastic film, and the outer bag is a woven bag or paper bag. The inner bag is detachably wrapped in the outer bag, and the length of the inner bag is longer than the length of the outer bag. This kind of package bag is widely used in the packaging of powder and granular materials in sugar, food, feed, chemical, starch, fertilizer and other industries. [0003] Patent document CN201710504366.6 discloses a set-type inner and outer bag material packaging automatic production line, which solves the problem of automatic material packaging using a set bag. Patent document CN201720749602.6 discloses a bag-clamping and bag-holding devic...

AI Technical Summary

Problems solved by technology

[0007] The purpose of the present invention is to provide a bag supporting device for a fully automatic line of packaged inner and outer bag material packaging, so as to overcome the problem that the guide rod and the guide sleeve seat in the prior art are easy to block when the bag supporting device is working, and the width of the bag cannot be controlled. The defect that the pressure is easy to cause damage to the strut cylinder
