Bag machine synchronous punching mechanism

Abstract

The invention discloses a bag machine synchronous punching mechanism. The bag machine synchronous punching mechanism comprises a first punching needle roller, a first grooved roller, a second punchingneedle roller and a second grooved roller which can sequentially clamp and punch woven fabric; one of the punching needle rollers is arranged on the upper surface of the woven fabric, and the other of the punching needle rollers is arranged on the bottom surface of the woven fabric; the first grooved roller and the second grooved roller are provided with protruded support arc surfaces. The bag machine synchronous punching mechanism can be matched with the cement industry to improve dust control and reduce dust overflow from breathing holes during cement packaging and truck loading processes of cement bags; without punching the surface of the lower half of a cement bag which is unnecessary for bearing, the bag machine synchronous punching mechanism synchronously punches the upper half of the cement bag to simultaneously meet the requirements of cement packaging on normal breathing and reduce the number of surface punched holes by 40%, thereby achieving the effect of reducing surface overflowed dust during packaging and transportation and meeting environmental requirements during production and application.

Description

technical field [0001] The invention relates to the field of cement woven bag manufacture. Background technique [0002] During the production of cement woven bags, it is necessary to perforate the surface to facilitate the discharge of the air in the bag when the cement is packaged. The current perforating mechanism is as follows: figure 1 As shown, two needle rollers are used to clamp the woven bag, and the surface of the woven bag is continuously punched. Due to the large number of holes in the woven bag, the bag surface is seriously overflowed with dust during the filling and shipping process, which affects the production and transportation links. Contents of the invention [0003] The technical problem to be solved by the present invention is to reduce the number of pinholes in cement woven bags, so as to achieve the effect of reducing dust overflow on the bag surface during filling and shipping, and meet the needs of production and environmental protection.
