Multilayer dislocation punching device

Abstract

The invention discloses a multilayer dislocation punching device, comprising a stand wall board, a bearing mounting base, paper passing rollers, needle rollers, rubber supporting rollers and a punching needle, wherein the bearing mounting base is mounted on the stand wall board; the rubber supporting roller is mounted on the bearing mounting base; the needle roller is further mounted on the bearing mounting base; the rubber supporting roller matched with the needle roller is mounted on the bearing mounting base by being matched with the needle roller; the punching needle is mounted on the needle roller; and three groups of punching mechanisms for individually working are respectively formed by the three needle rollers, the three rubber supporting rollers and the three paper passing rollers for guiding paper in pairs. Each layer of the paper sheet is punched by the multilayer dislocation punching device in a bag making process, so that holes are not flat and parallel to pass through. Therefore, filled materials are left in a body of a paper bag when a venting speed is greatly improved, so that not only can the filling speed be improved, but also the materials are saved; and the dust pollution problem in a filling field is solved.

Description

technical field [0001] The invention relates to the field of packaging bag manufacturing equipment, in particular to a multi-layer dislocation punching device. Background technique [0002] At present, paper bags are widely used in the packaging of powder materials. After filling, the paper bags have a square appearance, which is extremely convenient and safe for stacking and transportation. However, due to the large output, some industries require high filling speed when using paper bags, and some even require a bag to be filled in a few seconds, which puts forward higher requirements for the exhaust function of paper bags . The traditional solution is to punch a through hole on the surface of the paper. With the through hole exhaust, the pressure and speed during filling can be greatly increased. However, the filled material will be ejected from the through hole together with the discharged gas. Dust seriously pollutes the filling site and also brings waste. Contents o...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a multi-layer dislocation punching device, which punches holes for each layer of paper during the bag making process, and the holes will not be aligned to form a through hole, and the exhaust speed can be greatly improved. At the same time, the filled materials are left in the paper bag body, which not only improves the filling speed but also avoids material waste, and solves the problem of dust pollution on the filling site
