A separation device for zipper tape and sprue bar

Abstract

The invention provides a device for separating a zip fastener tap from a gate stick. The device comprises a driving device, a pushing component, a guide rail and a separation clamping roller, wherein the pushing component is connected with the driving device and can be driven by the driving device to do reciprocating motion to push the gate stick to move; the pushing component pushes the zip fastener tape and the gate stick to move on the guide rail; the separation clamping roller is arranged on the top of the guide rail and can apply a pressing force to chain teeth of the zip fastener tape moving on the guide rail, and an axial line of the separation clamping roller is inclined corresponding to a plane on which the guide rail is located. According to the device for separating the zip fastener tape from the gate stick, the separation clamping roller and the pushing component are used for respectively applying forces to the chain teeth and the gate stick, and this separation manner takes the place of the separation manner that an original friction wheel pulls cotton tapes, so that the probability of the cotton tapes to be damaged or broken because of the action of a pull force is reduced, even avoided, the influence on the connection firmness of the cotton tapes and the chain teeth is also avoided, and the product quality is effectively ensured.

Description

technical field [0001] The invention relates to the technical field of zipper manufacturing and preparation, more specifically, to a separation device for a zipper tape and a sprue bar. Background technique [0002] Zinc alloy zippers generally adopt zinc alloy die-casting molding process. In order to make the chain elements form smoothly during die-casting, in the process of using mold injection molding, there will be sprue bars 01 connected with the chain teeth 022 of the zipper tape 02, such as figure 1 As shown, in order to obtain the finished zipper, it is necessary to separate the sprue bar 01 from the zipper tape 02. [0003] In the prior art, the separation operation of the sprue rod 01 and the zipper tape 02 (the zipper tape 02 in this application includes the cloth tape 021 and the fastener elements 022 arranged on the cloth tape 021) generally includes manual separation and mechanical separation. operate. Among them, the manual separation operation is to manuall...

Problems solved by technology

[0004] However, in the process of the above-mentioned mechanical separation operation, since the friction wheel 04 exerts a traction force on the cloth tape 021 of the zipper tape 02, and the sprue bar 01 is connected with the fastener element 022, so the zipper tape 02 and the sprue bar When 01 is separated, the cloth belt 021 pulls the chain element 022 under the action of traction, so that the chain tooth 022 is separated from the sprue bar 01, and in this process, the cloth tape 021 is easily damaged by pulling, and in severe cases, it may even be pulled broken, and it will also affect the firmness of the connection of the chain tooth 022 on the cloth belt 021, and the quality of the product cannot be guaranteed
