Big bag unloading mechanism

Abstract

The invention discloses a ton bag unloading mechanism. The ton bag unloading mechanism comprises a carrying device and an unloading device, wherein the carrying device is used for bearing ton bags and putting the ton bags above the unloading device; the unloading device comprises a vertically arranged unloading cylinder; the unloading cylinder comprises an outer cylinder and an inner cylinder arranged on the inner side of the outer cylinder in a clearance way; the upper end of the unloading cylinder is provided with a feeding hole of the unloading device; the lower end of the unloading cylinder is provided with a discharge hole of the unloading device; the feeding hole is right opposite to a bag opening of each ton bag. According to the ton bag unloading mechanism, the unloading cylinder is of a double-layer structure with the outer cylinder and the inner cylinder, inner bag openings are positioned in the inner cylinder, outer bag openings are positioned between the inner cylinder and the outer cylinder, and channels for materials in the ton bags with the outside are reduced, so that dust diffusion is reduced and the working environment is effectively improved; meanwhile, dust is settled and recycled, so that the material loss is reduced.

Description

technical field [0001] The invention relates to an unloading mechanism, in particular to a large bag unloading mechanism. Background technique [0002] The ton bag is a flexible transport packaging container, which has the advantages of moisture-proof, dust-proof, radiation-resistant, firm and safe, and is widely used in the packaging of various powdery, granular, and massive items such as chemicals, building materials, plastics, and mineral products. [0003] The Chinese invention patent application with the publication number CN103407797A discloses a ton bag feeding device and a feeding method, including a support device, a ton bag holding and turning mechanism, a turning power mechanism, a collecting hopper, a belt scale, and a vacuum adsorption device; Put the material in the turning cage, hang the lifting lug of the big bag on the hook of the big bag; the vacuum suction head is compressed and close to the bottom of the big bag, start the vacuum device, the vacuum suctio...

AI Technical Summary

Problems solved by technology

When the ton bag feeding device disclosed in the above-mentioned Chinese invention patent application is in use, the powdery material is dumped onto the collecting hopper, which generates relatively large dust. On the one hand, it makes the working environment harsh, and on the other hand, the large dust makes the material loss more Big
