Embodiment Construction

[0015] Renovate a set of punching device that is synchronized with the main machine and matches the layout at the punching part of the bag making machine. The position of the synchronous punching is located in the upper half of the packaging bag. The punching area can be set according to needs, for example, it occupies about 100% of the bag surface. 60%.

[0016] The synchronous punching mechanism of the bag making machine is equipped with the first punching needle roller 2 and the first grooved roller 3 to clamp and punch the woven cloth 1 in sequence, and the second punching needle roller 4 and the second grooved roller 5. The first punching needle roller 2, the first grooved roller 3, the second punching needle roller 4 and the second grooved roller 5 are connected and driven by the same motor through a chain drive to keep synchronously, and the second punching needle roller 4 and the second grooved roller 5 rotate in opposite directions, the second punching needle roller 4...

Abstract

The invention discloses a synchronous punching mechanism of a bag making machine. The punching mechanism is provided with a first punching needle roller and a first grooved roller clamping and punching a woven cloth sequentially for punching holes, and a second punching needle roller and the second grooved roller, one of the first punching needle roller and the second punching needle roller is located on the upper surface of the woven cloth, and the other is located on the lower surface of the woven cloth, the first grooved roller and the second grooved roller There is a supporting curved surface protruding from its surface. The present invention can cooperate with the cement main business to continuously improve the dust control of the cement packaging and loading links, reduce the dust overflow of the ventilation holes in the cement packaging bag during the packaging and loading process, and prevent the lower half of the packaging bag surface from being used for ventilation. Then punch holes, but synchronously punch the upper part of the bag body, and reduce the number of holes punched on the bag surface by 40% under the condition of meeting the normal ventilation requirements of cement packaging, so as to reduce the overflow of the bag surface during filling and shipping. The effect of dust can meet the needs of production and environmental protection.

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. [0004]...
