Problems solved by technology

During this period, the inwardly folded edge of the dust-retaining liner is flush with the cut edge of the bag body, and the width of the dust-retaining liner after folding and curling is not enough to completely cover the pinhole, resulting in poor sealing performance of the cement packaging bag. Well, the phenomenon of ash leakage during the packaging and transportation of cement is serious, which not only causes the loss of cement, but also the cement in the packaging bag is easy to absorb moisture when stacked, which shortens the shelf life, and the two lines sewn are very important for preventing leakage of ash. It has no practical effect and increases the consumption of sutures. In addition, because it needs to be wrapped with kraft paper during sewing, although it has a certain protective effect on the sewing edge, there is still a phenomenon of dust leakage

Abstract

The invention provides a method for preventing a cement bag from leaking ash, and a cement bag sealing device. The cement bag sealing device comprises a stand, and an ash blocking gasket positioning mechanism, a filling port forming mechanism, a bag pressing mechanism, an edge rolling mechanism and a bag sewing mechanism which are fixed on the stand; the ash blocking gasket positioning mechanism comprises a positioning push block, a positioning cylinder, an air pipe and an air pump; the interior of the positioning push block is of a hollow structure; multiple exhaust holes are formed in one side of the positioning push block; an intake port protruding from the surface of the positioning push block is welded to the part, at the side opposite to the exhaust holes, of the positioning push block; the intake port is connected with the air pump through the air pipe; and the edge rolling mechanism comprises a double-layer edge rolling former and a pressing piece which are positioned on the head and tail sides of a bag body. By tailoring the cement bag, precisely positioning an ash blocking gasket, performing double-layer edge rolling and sewing the cement bag with a line of threads, the ash blocking gasket is provided with an enough large blocking face for blocking pinholes during filling of cement, so that the ash leakage phenomenon is effectively prevented, the pollution and the waste are reduced, and the consumption of sewing threads is reduced.

Description

technical field [0001] The invention relates to the technical field of cement packaging, in particular to a method for preventing cement bag ash leakage and a cement bag sealing device. Background technique [0002] In the cement bag making process, the cement bag is generally cut first to form the cement bag's collar and the dust-retaining liner, and then the dust-retaining liner is folded inside the cement bag. After one curling, the double-needle sewing machine is used Sew two lines where the hem is. During this period, the inwardly folded edge of the dust-retaining liner is flush with the cut edge of the bag body, and the width of the dust-retaining liner after folding and curling is not enough to completely cover the pinhole, resulting in poor sealing performance of the cement packaging bag. Well, the phenomenon of ash leakage during the packaging and transportation of cement is serious, which not only causes the loss of cement, but also the cement in the packaging bag...
