Bottom forming machine of square bottom paper bag

Abstract

The invention relates to a bottom forming machine of a square bottom paper bag, and the bottom forming machine comprises a bag mouth turnover and line pressing part, a bag bottom turnover and line pressing part, a bottom pulling formation part, a bag bottom forming part, a bottom sealing part and a large roller; the large roller drives the parts to synchronously work according to a preset working procedure; a first line pressing cutter is arranged on the bag mouth turnover and line pressing part; a second line pressing cutter and a third line pressing cutter are arranged on the bag bottom turnover and line pressing part; the bottom pulling formation part comprises a suction nozzle and a mouth pulling roller of a first tooth-type pressure block; the bag bottom forming part comprises an arc-shaped formation guide rod, a formation baffle, a bag bottom pressure roller, a gum-printing roller, a bag bottom line pressing cutter, a folding cutter and a bottom sealing support rod; the bottom sealing part comprises a variable speed bottom sealing rod, a bottom sealing circular arc-shaped plate and a connecting roller with a connecting holding tooth claw; and the large roller is provided with a large finger-type pressure block, a small finger-type pressure block, a second tooth-type pressure block, a paper suction jaw, a paper clamping jaw and a paper holding tooth claw, and is driven to work by an internal driving mechanism. According to the bottom forming machine of the square bottom paper bag, the full-automatic continuous work of the bottom formation of the square bottom paper bag can be realized.

Description

technical field [0001] The invention belongs to paper bag making equipment, in particular to a bottom hooking machine (or bottom sealing machine) for square bottom paper bags. Background technique [0002] At present, the bottom hook (or bottom cover) of the square bottom paper bag is mostly manually operated, and the paper tube is manually folded and glued. The work efficiency is low and the quality is difficult to guarantee. Although there is also a machine suitable for forming the bottom of a paper bag, the structure is complex and the work is unstable. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a bottom hooking machine (or bottom sealing machine) that can work continuously, has high production efficiency and stable work, and is suitable for forming the bottom of square bottom paper bags. [0004] The technical solution adopted in the present invention is: a bottom-hooking machine for square-bottomed pap...
