Automatic bag opening machine

Abstract

The invention relates to the technical field of bag opening equipment, and provides an automatic bag opening machine. The automatic bag opening machine comprises a machine frame body, a moving frame,a lifting mechanism, a cutting knife assembly and a material receiving hopper, wherein the moving frame, the lifting mechanism, the cutting knife assembly and the material receiving hopper are arranged on the machine frame body; a bag grabbing assembly is arranged on the moving frame and comprises at least one group of rotary shaft group, each rotary shaft group comprises two bag grabbing rotary shafts with opposite rotation directions, and a plurality of grabbing hooks are symmetrically arranged on the two bag grabbing rotary shafts. According to the automatic bag opening machine, the liftingmechanism, the moving frame, the cutting knife assembly and the material receiving hopper are arranged on the machine frame body, and the bag grabbing assembly is arranged on the moving frame; afterpackaging bags are lifted, the bag grabbing assembly tightly catches the packaging bags and sends the packaging bags to the upper part of the material receiving hopper by the moving frame; and in theprocess, the cutting knife assembly continuously cuts the lower parts of the packaging bags to form a plurality of cutting openings, and materials flow into the material receiving hopper from the cutting openings. In the whole process, material lifting and material dropping are separated, and the structure of equipment is optimized. The packaging bags are cut from the bottoms in the feeding process, and the material dropping efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of bag unpacking equipment, in particular to an automatic bag unpacking machine. Background technique [0002] At present, powder or granular materials are basically packaged in sealed packaging bags. When unpacking, most of them adopt manual unpacking, which is labor-intensive and low in work efficiency. [0003] The patent with the application number CN201711480243.X discloses an automatic manipulator bag unpacking machine, which is provided with a lifting member and a cutting member at the top, and a discharge hopper at the bottom. The lifting member is used to lift the packaging bag upwards, the cutting member starts to cut it, and the material falls into the discharge hopper; then the grabbing member grabs the packaging bag, and the cutting member continues to cut the middle of the packaging bag; so that all the materials Drop into the unloading hopper; finally the grabbing member unloads the empty ba...

AI Technical Summary

Problems solved by technology

However, this equipment has the following disadvantages: 1. The packaging bag is not restricted in the initial stage of cutting, and the cutting knife is prone to slipping when it first contacts, which affects the cutting effect; 2. The packaging bag is cut from the upper part, which affects the efficiency of blanking; and cutting The blanking is completed on the lifting member, and the powder produced by blanking affects the service life of the parts in the lifting member; 3. The grabbing member has a complex structure and many components. These parts are easy to hook the bag during use. The empty bag cannot be unloaded smoothly, thus affecting the completion of subsequent actions

[0005] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
