High-speed bag machine

Abstract

The invention discloses a high-speed bag machine. The high-speed bag machine comprises a finished product input unit, a product folding unit, a product transfer unit, a binding unit and a product output unit; and the middle part of a middle pressing plate of the product holding unit is hollowed. As the middle part of the middle pressing plate is hollowed, an indentation step is performed when primary folding is performed, the whole folding process time can be shortened by about 20%, and the working efficiency of the machine is obviously improved; upper and lower driving cylinders can be used for moving up to leave away from plastic bags when the middle pressing plate is returned, and then, move back to return, so that the indentation leveling phenomenon in the backward moving process is effectively prevented, and the folding effect is guaranteed; a pressing plate width adjusting device and a support plate width adjusting device can be used for adjusting the widths of a plastic bag lifting belt support plate and the middle pressing plate according to the widths of products, so that the adaptability of the machine is improved; and the unfolded products or folded products can be directly output as needed, so that two functions are achieved.

Description

technical field [0001] The invention relates to a high-speed bag making machine, belonging to plastic bag making equipment. Background technique [0002] The raw material bag making machine of the prior art generally includes a front process, a finished product input unit, a product folding unit, a product transfer unit, a strapping unit and a product output unit. The mouth unit, the finished product input unit will input the finished product of the vest-shaped plastic bag after being punched by the punching unit to the product folding unit, which will fold the finished plastic bag and transport it to the strapping unit through the product transfer unit for bundling , and finally output by the product output unit to complete the entire bag-making process. The product folding unit includes: a front corner folding mechanism for folding the two handles at the front end of the vest-shaped plastic bag to the middle; a front flap for folding the front of the finished plastic bag ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a high-speed bag-making machine to solve the problem of low working efficiency in the prior art; during the process of moving the middle pressing plate backwards and resetting, it will flatten the indentation already pressed out by the indentation plate, which will affect the folding effect; The platen is of fixed width, the applicability of the machine is poor; and the problem of single function
