With continued reference to fig. 8-10, when the slider conveying driving element 521 drives the slider conveying connecting plate 524 and the slider carrying block 525 to move to the rear end, as shown in fig. 8-9, the slider accommodating groove 525a on the slider carrying block 525 is abutted to the outlet of the slider feeding channel 512, and at this time, the slider pushing assembly 513 can push the slider into the slider accommodating groove 525 a; when the slider conveying driving member 521 drives the slider conveying connecting plate 524 and the slider bearing block 525 to move to the front end, as shown in fig. 10, the front end of the slider bearing block 525 extends into the slider clamping mechanism 53, so that the slider on the slider accommodating groove 525a can be accessed by the slider clamping mechanism 53.

Referring to fig. 6 and 12-17, a slider holding mechanism 53 is provided at the discharge end of the slider conveying mechanism 52 on the conveying path of the lateral conveying device 4, and holds a single slider conveyed by the slider conveying mechanism 52 so that a threading process can be performed when a fastener tape of a semi-finished product passes therethrough.

Specifically, the slider clamping mechanism 53 includes a slider clamping upper and lower cylinder 531, a telescopic end of the slider clamping upper and lower cylinder 531 is fixedly connected to a slider clamping upper and lower slider 532, the slider clamping upper and lower slider 532 is slidably disposed on a slider clamping upper and lower slide rail 533, an upper end of the slider clamping upper and lower slider 532 is connected to a seat 538, as shown in fig. 13, a fixing clip 534, a rotating clip 535, and a rotating clip driving cylinder 536 are mounted on the seat 538.

When the rotating clamp driving cylinder 536 drives the first linear moving block 537 to reciprocate linearly up and down, the first linear moving block 537 drives the rotating clamp 535 to rotate around the pivot shaft at the lower end thereof, so that the upper end of the rotating clamp 535 can rotate to close with the fixing clamp 534 to form a state of clamping the slider, and can also rotate away from the fixing clamp 534 to open so that the slider is pulled out along with the semi-finished product zipper tape.

Therefore, when the pulling cylinder 541 drives the second linear moving block 542 to reciprocate linearly up and down, the second linear moving block 542 drives the rotating link 543 to rotate around the rotating shaft at the corner thereof, thereby driving the pulling hook 544 to rotate synchronously, so that the hook at the upper end of the pulling hook 544 can rotate to pull the pull tab of the slider downwards.

Referring to fig. 6 again, in the present invention, the second threading device 6 also includes a slider feeding mechanism 61, a slider conveying mechanism 62, a slider clamping mechanism 63, and a pull tab opening mechanism, and the structures of the respective parts are the same as those of the first threading device 5, and the structures of the respective parts are arranged symmetrically to those of the first threading device 5, so that the description is not repeated.

As shown in fig. 6 to 17, when performing the double-slider threading operation, first, the slider conveying mechanism 52 of the first threading device 5 conveys the first slider to the slider clamping mechanism 53, and the head of the first slider clamped by the slider clamping mechanism 53 faces the front end, and correspondingly, the slider conveying mechanism 62 of the second threading device 6 conveys the second slider to the slider clamping mechanism 63, and the head of the second slider clamped by the slider clamping mechanism 63 faces the rear end, that is, the heads of the first slider and the second slider face the opposite direction.

When the first gripper 413 and the second gripper 423 of the transverse conveying device 4 grip both tapes of the fastener tape semi-finished product, respectively, the first transverse driving element 411 drives the first longitudinal driving element 412 to move in the transverse direction, and the second transverse driving element 421 drives the second longitudinal driving element 422 to move in the transverse direction, i.e., to slide in the direction indicated by the arrow F1 in fig. 6 to 7, thereby pulling the fastener tape semi-finished product to move toward the first threading device 5.

While moving in the overall lateral direction, the first clamp 413 is driven by the first longitudinal driving member 412 to move in the direction indicated by the arrow F3 in fig. 6-7, and the second longitudinal driving member 422 drives the second clamp 423 to move in the direction indicated by the arrow F4 in fig. 6-7, that is, the first clamp 413 and the second clamp 423 move back and forth synchronously in the longitudinal direction, even if the first clamp 413 and the second clamp 423 are separated relatively synchronously, thereby pulling both tapes of the fastener tape of the semi-finished product to open the upper end portions thereof, that is, to tear the fastener elements on both tapes of the fastener tape of the semi-finished product apart; then, the first longitudinal driving element 412 drives the first clamp 413 to move in the direction indicated by the arrow F4 in fig. 6-7, and the second longitudinal driving element 422 drives the second clamp 423 to move in the direction indicated by the arrow F3 in fig. 6-7, so that the first clamp 413 and the second clamp 423 slide synchronously toward each other in the longitudinal direction to close, and the two tapes of the semi-finished product fastener tape close but the fastener elements are still in a separated state. The first transverse driving element 411 drives the first longitudinal driving element 412, and the second transverse driving element 421 drives the second longitudinal driving element 422 to continue synchronous transverse movement, so that the semi-finished zipper tape passes through the slider clamping mechanism 53 of the first threading device 5, and the first slider is threaded on the semi-finished zipper tape. Since the head of the first slider is directed toward the front end (i.e., toward the traveling direction), the first slider closes the fastener elements on the two separated tapes in the threading process, that is, the upper end of the fastener tape of the semi-finished product is in a closed state at this time.

When the row of the fastener tape of the semi-finished product reaches a position between the first and

second threading devices

5 and 6, the first longitudinal driving member 412 drives the first clamp 413 to move again in the direction indicated by the arrow F3 in fig. 6 to 7, and the second longitudinal driving member 422 drives the second clamp 423 to move in the direction indicated by the arrow F4 in fig. 6 to 7, even if the first and

second clamps

413 and 423 are synchronously moved back and forth in the longitudinal direction to be relatively separated again, thereby tearing the fastener elements on both tapes of the fastener tape of the semi-finished product again, that is, bringing the upper end portion of the fastener tape of the semi-finished product into an open state. Then, the first transverse driving element 411 drives the first longitudinal driving element 412, and the second transverse driving element 421 drives the second longitudinal driving element 422 to continue synchronous transverse movement, so as to pull the semi-finished zipper tape to pass through the zipper head clamping mechanism 63 of the second zipper head penetrating device 6 and penetrate the second zipper head. Since the head of the second slider faces the rear end (i.e., faces away from the traveling direction), the fastener elements on the two tapes penetrating through the fastener tape of the semi-finished product of the second slider are still in an open state.

After the threading is completed, the first transverse driving element 411 drives the first longitudinal driving element 412, and the second transverse driving element 421 drives the second longitudinal driving element 422 to continue to synchronously move transversely, so as to convey the semi-finished zipper tapes with the first and second sliders to the upper stop forming device 7.
