A mouth tensioning device for ton bags

Abstract

An opening tensioning device of ton bag includes a support which is provided with a chute and a cantilever. The guide wheels located in the chute is arranged on one side of the cantilever. A first push rod is arranged below the cantilever and used for pushing the cantilever to move vertically along the chute. A barrel is fixed in the middle of the cantilever for allowing a work head to enter. The barrel is sleeved with an opening of the ton bag. A brace rod is hinged to the barrel. The cantilever is provided with fixed arms on both sides of the work head, and each fixed arm is connected with a clamping mechanism which includes a second push rod hinged to the top of the fixed arm. The extension end of the second push rod is connected with a lever unit in a hinged mode, and the bottom of the lever unit is connected with each sliding block. A chuck is fixed at the bottom of each sliding block, pushes the lever unit to move through the second push rod, drives the sliding block to move and further drives the chuck to move towards the barrel and clamp the ton bag. The above devices enable the ton bag to be tensioned constantly during material discharge and ensure that all materials in the ton bag are discharged without any residues, and the ton bag can be reutilized.

Description

technical field [0001] The invention belongs to the technical field of powder engineering, and in particular relates to a mouth tensioning device for ton bags. Background technique [0002] In industrial production, the powder or small granular materials packed in ton bags need to be transported back to the storage warehouse or on-site transportation equipment after being transported. Generally, the packaging bags are made of soft packaging materials. [0003] The existing reversing method, one is to use the crane method, that is, the crane is directly hoisted to the top of the storage bin, and the ton bag is manually cut to make the material fall directly into the bin; the other is to use the dumping method, Dumping by turning equipment or manual turning. Both of these two methods have the disadvantages of dust pollution, poor working environment, low labor productivity, and many residual materials in the ton bag, and when the first method is used, the ton bag cannot be re...

Problems solved by technology

Both of these two methods have the disadvantages of dust pollution, poor working environment, low labor productivity, and many residual materials in the ton bag, and when the first method is used, the ton bag cannot be reused, which seriously affects the economic benefits of the enterprise; When using the second method of reversing, if turning equipment is used, there will be a lot of material residues in the ton bags. If manual turning is used, dust pollution will cause workers to feel uncomfortable, the working environment is poor, and the efficiency of manual turning is low.
