Bag making machine with conveyor traction device

Abstract

The invention relates to a belt conveying and drafting device for a bag making machine. The belt conveying and drafting device is characterized by comprising fixed bases, air cylinders, an air cylinder installing plate, sliding blocks, an upper supporting shaft, a lower supporting shaft and pressure roller assemblies; the two fixed bases are arranged in parallel; the two ends of the lower supporting shaft are installed on the two fixed bases respectively in a supported manner and locked through nuts; the air cylinder installing plate is installed at the tops of the two fixed bases; the two ends of the air cylinder installing plate are each provided with one air cylinder; the two fixed bases are each internally provided with one sliding block capable of sliding up and down; the piston rod ends of the air cylinders are downwards connected with the sliding blocks; the upper supporting shaft is arranged above the lower supporting shaft; the two ends of the upper supporting shaft are installed on the sliding blocks at the corresponding ends respectively in a supported manner; and the upper supporting shaft and the lower supporting shaft are each provided with the pressure roller assemblies, wherein the pressure roller assemblies on the upper supporting shaft and the pressure roller assemblies on the lower supporting shaft are equal in number, and the front faces of the pressure roller assemblies on the upper supporting shaft and the front faces of the pressure roller assemblies on the lower supporting shaft are vertically opposite. The belt conveying and drafting device is compact in structure and easy to operate, labor intensity can be lowered, and labor productivity can be increased.

Description

technical field [0001] The invention relates to a traction device, in particular to a bag-making machine belt conveying traction device for a large-scale bag-making machine, and belongs to the technical field of bag-making machine equipment. Background technique [0002] With the continuous development of the economy, the market has higher and higher requirements for the product quality of the bag making machine. The traction capacity of the bag making machine has a great influence on the product quality during the production process. Currently, most of the bag making machines on the market use upper and lower The traction mode of mutual pressure of rubber rollers is not flexible enough, and it is easy to cause damage to the plastic film, which affects the production efficiency and market competitiveness of the enterprise. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art, and provide a bag-making machin...
