Bag-feeding mechanism and control method of bag-feeding packaging machine, and bag-feeding packaging machine

Abstract

The invention particularly relates to a bag feeding mechanism of a bag feeding type packaging machine, a control method and the bag feeding type packaging machine. The bag feeding mechanism comprises a first driving mechanism, a second driving mechanism, a first annular conveying belt driven by the first driving mechanism to rotate and a second annular conveying belt driven by the second driving mechanism to rotate. The first annular conveying belt and the second annular conveying belt are horizontally and oppositely arranged in the vertical direction. The first annular conveying belt is connected with a plurality of first clamps, the second annular conveying belt is connected with a plurality of second clamps in one-to-one correspondence with the first clamps, and each first clamp and the corresponding second clamp form a bag clamping device. The bag feeding mechanism of the bag feeding type packaging machine is simple in structure, stable in operation and capable of effectively improving production efficiency.

Description

technical field [0001] The invention relates to the field of packaging production, in particular to a bag-feeding mechanism and a control method of a bag-feeding packaging machine, and a bag-feeding packaging machine. Background technique [0002] The existing bag-feeding packaging machines at home and abroad are generally composed of a frame, an electric control box, a bag feeding mechanism, a prefabricated bag transfer mechanism, a blanking mechanism, a pre-sealing mechanism, a shaping and sealing mechanism, and a finished product conveying mechanism. The main functions of the bag packaging machine are: grabbing the prefabricated bag (made of plastic film), clamping the prefabricated bag and opening the bag mouth, filling the material, and heat sealing the mouth, so that the material is packaged and sealed in the prefabricated bag. The bag feeding mechanism of the existing bag-feeding packaging machine generally adopts two pairs of bag clamping plates that are opened and m...

AI Technical Summary

Problems solved by technology

Therefore, there are following defects in the existing bag-feeding packaging machine: 1, use the structure of the first pair of bag clamping plates and the second pair of bag clamping plates, the structure is complicated, and the space position of the prefabricated bag can be occupied, so that the volume of filling is reduced ; Alternate actions will reduce the running speed, and because of the complicated actions, it is easy to cause mistakes, resulting in bag clamping failure, material filling failure and scattering, sealing misplaced products and scrapping, etc., thereby reducing production efficiency; Each station adjusts the position of the clamping column independently, which increases the labor intensity and requires high technical skills for the workers, which obviously reduces the production efficiency.
