Description
Technical Field
The invention relates to seamless installation equipment of a zipper, in particular to a cloth pressing and gluing integrated machine of a seamless zipper bag.
Background
The zipper is widely applied in the fields of clothing, bags and the like. Referring to fig. 1, a slide fastener generally comprises two fastener tapes 111, each fastener tape 111 having a row of fastener elements 112, and a slider 113 for holding the fastener elements 112 on both sides, and the fastener elements 112 on both sides are engaged with or disengaged from each other by sliding the slider. When the conventional slide fastener is installed and used, two chain belts 111 are sewn at the installation position through sewing equipment, and after the sewing is finished, the chain belts 111 have obvious sewing marks, so that the conventional slide fastener is not attractive when being applied to a pocket of clothing.
To solve this problem, seamless slide fasteners are increasingly developed in the market, and the process of attaching such slide fasteners: 1. a first layer of viscose 102 is bonded at the mounting position of the cloth piece 101 in a hot-pressing way; 2. cutting an elongated first through hole 104 at the position where the glue is present; 3. a second layer of adhesive 103 is bonded on the other surface of the cloth piece 101 in a hot-pressing way, a long second through hole 105 is formed in the second layer of adhesive 103, the second through hole 105 is smaller than the first through hole 104, when the second layer of adhesive 103 is bonded, the first through hole 104 on the cloth piece 101 surrounds the second through hole 105 on the second layer of adhesive 103, so that the outer side part of the second layer of adhesive 103 is bonded with the cloth piece 101, and the inner side part of the second layer of adhesive 103 extends into the first through hole 104; 4. the zipper is aligned with the second through hole 105 on the second layer of viscose glue 103, and then the slider 113 of the zipper passes through the second through hole 105 from bottom to top, so that the chain belt 111 enters the first through hole 104 and is adhered with the second layer of viscose glue 103, and then the bonding part of the zipper and the cloth piece 101 is hot-pressed by a hot press, so that the seamless installation of the zipper can be completed, and the appearance is attractive and firm.
In the prior art, in the step 3, the second layer of adhesive 103 is aligned with the first through hole 104 of the cloth piece 101 by manual operation, so that the precision is difficult to ensure; in addition, for a large-thickness cloth piece, the part of the cloth piece, to which the second layer of adhesive 103 is adhered, must be flattened before the second layer of adhesive 103 is adhered, so as to avoid wrinkling of the cloth piece 101 or the second layer of adhesive 103 due to compression when the second layer of adhesive 103 is adhered by hot pressing. The two working procedures are carried out on different equipment separately, and the working efficiency is low.
