Paper splitting device

Abstract

The invention relates to a paper splitting device comprising a rubber roller (1), a splitting rubber roller (2), a splitting roll shaft (3), two splitting roll shaft flanges (4), a splitting roll shaft synchronizing wheel (8), a rubber roller gear (9) and two wall boards (10), wherein two ends of the splitting roll shaft (3) penetrate through the splitting flanges (4) and are installed on the wall boards (10), one end of the splitting roll shaft (3) penetrates through the wall boards (10) and is connected with the splitting roll shaft synchronizing wheel (8); the splitting rubber roller (2) is installed on the splitting roll shaft flanges (4), a gap is formed between the splitting rubber roller (2) and the splitting roll shaft (3); the rubber roller (1) is installed on the wall boards (10) and positioned below the splitting rubber roller (2), a gap is formed between the rubber roller (1) and the splitting rubber roller (2), and one end of the rubber roller (1) penetrates through the wall boards (10) and is connected with the rubber roller gear (9). The paper splitting device provided by the invention can conveniently split needle pricked paper with accurate size, is suitable for paper of all sizes, can improve the rate of finished products in production of paper bags, and greatly reduces loss.

Description

technical field [0001] The invention relates to a paper tearing device of a paper bag machine suitable for producing pointed-bottom paper bags, belonging to the technical field of packaging equipment. Background technique [0002] Existing paper bag machines often use cams to tear the paper after piercing holes in the production of paper bags. When the cam is used to tear the paper, the cam curve is easy to generate acceleration, which causes uneven force on the paper when it is torn, and the paper is easy to move up and down. Therefore, it is difficult for the paper to be fully synchronized with the bottom folding before the bottom folding, resulting in errors in the size of the processed paper bag, which affects the quality of the product. At the same time, when the cam is broken, the cam cannot adapt to high-speed operation, and the production efficiency cannot be improved. Contents of the invention [0003] The object of the present invention is to overcome the de...
