The unloading device of the open bag automatic filling machine

Abstract

A feeding device for an automatic open bag filling machine belongs to the technical field of packaging machinery, and comprises a frame, a hanging bracket, a dual-stroke acting cylinder, a clamping acting cylinder link mechanism and a pair of bag mouth clamping acting cylinders. The feeding device is characterized by comprising a feeding device assembly. The feeding device assembly comprises a cantilever crane, a lower connecting frame, a lower hopper supporting bottom plate, a lower hopper, a feeding guide pipe, a left bag opening door, a right bag opening door, a bag opening door opening and closing mechanism and a cantilever crane actuating acting cylinder. Cantilever crane supporting shaft head fixing plates are respectively fixed at the left ends on the front side and the right side of the cantilever crane. A front lower connecting frame fixing plate connecting seat and a right lower connecting frame fixing plate connecting seat are arranged at the inclined right ends of the front side and the rear side of the cantilever crane. A front lower connecting frame fixing plate is arranged in the middle on the front side of the lower connecting frame. A front lower connecting frame fixing plate pin shaft is arranged at the lower end of the front lower connecting frame fixing plate. A rear lower connecting frame fixing plate is arranged in the middle on the right side of the lower connecting frame. A rear lower connecting frame fixing plate pin shaft is arranged at the lower end of the rear lower connecting frame fixing plate. A feeding guide pipe mounting pipe is arranged in the middle of the lower hopper supporting bottom plate. Materials in the feeding hopper are enabled to fall into a bag for filling by the feeding guide pipe, and the mounting and the using are facilitated.

Description

technical field [0001] The invention belongs to the technical field of packaging machinery, and in particular relates to an unloading device of an open bag automatic filling machine, which is matched with an open bag automatic filling and palletizing production line. Background technique [0002] The aforementioned open bag is widely used for fine chemical raw materials such as ultra-fine powder, metal ore and non-metallic ore powder, pharmaceutical and chemical raw materials, dyes, pigments, calcium carbonate, kaolin, phenolic resin and even food such as flour, seasoning, etc. Such as powder or granular material packaging. Since the open bag automatic filling machine has the advantages of high filling efficiency, accurate measurement, less manpower input and helping to reduce the work intensity of workers, it is widely used in the production industry not limited to the aforementioned products. [0003] As known in the industry, the main functions of the aforementioned open...

Problems solved by technology

Although this structure can meet the requirement that the discharge pipe (the patent name is "discharging sleeve") of the structural system of the discharge device is always aligned with the center of the bag opening and ensures smooth discharge, but the complex structure is its shortcoming. For example, it needs to be equipped with A bulky and troublesome material receiving box makes the overall structure of the open bag automatic filling machine less concise

Especially because the filling and discharging bag clamping mechanism recommended by this patent does not have the effect of making the two sides of the middle area of ​​the pocket opening of the open-mouth bag repel towards the direction away from each other, so that the unloading of the structural system of the unloading mechanism The feeding state of the tube is out of the bag instead of into the bag. The self-evident lack of out of the bag is easy to cause dust dispersion, which affects the working environment on the one hand and wastes resources on the other hand.
