Zipper slider inverted inserting machine with slider forward-inserting zipper tape

Abstract

The zipper reverse threading machine for the slider to pass through the zipper tape includes: a zipper tape action system, which includes a zipper tape feeding device, a hook tape positioning device and a pressing tape fixing device, which are respectively used for feeding the zipper tape, positioning and fixing; a slider action system, which includes a slider conveying device and a slider clamping device, respectively used to transport and clamp the slider; a control system, which is used to control the action of the zipper tape system, the operation of the slider action system; the slider action system also includes a slider threading device, which is used to drive the slider to move forward, so that the slider is threaded on the zipper tape. In the zipper reverse threading machine of the present invention, the zipper tape only moves forward in a step-by-step manner, and a slider threading device is used to drive the slider to move forward when the zipper tape is stationary, so as to thread the slider on the zipper tape. Since the zipper tape does not need to move alternately in the forward and reverse directions, the zipper tape is less prone to misalignment.

Description

technical field [0001] The invention relates to the technical field of zipper manufacturing, in particular to a zipper reverse threading machine. Background technique [0002] A zipper is usually composed of a zipper tape and a slider. In the manufacturing process of the zipper, one step is to put the slider on the zipper tape. The current automatic production generally uses a zipper threading machine to automatically complete the threading step. To better adapt to the subsequent process, use the zipper reverse threading machine to put the slider upside down on the zipper tape. The current zipper reverse threading machine first feeds the zipper tape to the assembly position in the forward direction, then transports the slider to the assembly position and fixes it, and then drives the zipper tape to pass through the slider reversely through a rewinding device. Finally, the zipper tape and the slider on it are discharged in the forward direction together. [0003] When the e...

Problems solved by technology

[0003] When the existing zipper reverse threading machine is working, the zipper tape is fed in the forward direction first, then reverses the slider in the reverse direction, and finally is discharged in the forward direction. The continuous and soft zipper tape alternates in the forward and reverse directions. Movement makes the overall structure of the zipper reverse threading machine more complicated, and the zipper tape is prone to misalignment, which makes the whole machine unable to work normally
