Paper bag machine and paper upper-opening folding device

Abstract

The invention discloses a paper bag machine and a paper upper-opening folding device. The paper upper-opening folding device comprises a support assembly and an upper-opening folding assembly, wherein the support assembly comprises a support rod, a paper through plate and a paper cushion block, the paper through plate is arranged on the upper surface of the support rod, the outer end of the paper through plate is bulged on the outer side surface of the support rod, the rear side surface of the paper cushion block is in close fit with the support rod and the inner end surface of the paper through plate, and the upper surface of the paper cushion block is in the shape of a downwards-inclined slope; the upper-opening folding assembly comprises a stop plate and a bent piece, the stop plate is fixed at the upper end of a stop plate fixing rod, the bottom surface of the stop plate is in fit with the upper surface of the paper cushion block, the bent piece is arranged at the upper end of the stop plate, a slide groove is formed in the upper end of the bent piece, and the upper and lower positions of the bent piece can be adjusted with the slide groove. According to the paper bag machine and the paper upper-opening folding device disclosed by the invention, a paper upper-opening folding process is finished for the conveyed paper according to upper-opening indentations by using the stop plate and the bent piece; the paper bag machine and the paper upper-opening folding device are simple in structure, convenient for operating personnel to assemble and debug the device, capable of realizing the upper-opening folding process on the paper bag machine, multi-purpose, capable of increasing the production efficiency, and wide in practicability.

Description

technical field [0001] The invention relates to a mechanical device for packaging bags after printing of paper products, in particular to a paper bag machine and a paper folding upper opening device. Background technique [0002] Portable paper bags are one of people's daily necessities. Portable paper bags can be used as shopping bags, clothing bags, gift bags, etc. for people to carry and use. Portable paper bags are processed by paper bag machines. [0003] However, the traditional paper bag machine cannot realize the paper folding process. Generally, the realization of this process must be completed in advance on other machines (such as folding machines), and then the folded paper is formed on the paper bag machine. Since the paper processing and folding process need to be realized on two machines, the production efficiency is reduced, and the production cost of the processor is increased at the same time, which is very inconvenient.
