[0013] Figure 2 It is Figure 1 It is the overall structural drawing of the clamping jaw. CONCRETE IMPLEMENTATION

[0014] The utility model will be further described in the embodiment combining the drawings.

[0015] Refer to Figure 1As shown, the belt rotating device of the embodiment comprises a belt rotating base 31, a rotating motor 32 and a belt rotating clamp 33. The body of the rotating motor 32 is fixedly installed on the belt rotating base 31. The belt rotating clamp 33 is in the shape of a long strip, the middle part of which is fixedly installed on the rotating shaft of the rotating motor 32. The two ends of the belt rotating clamp 33 are respectively provided with a clamping jaw 34 for clamping the zipper tape. In the process of belt rotating operation, the zipper tape delivered by the belt feeding device 2 is first clamped by one clamping jaw 34 and cut off by the belt feeding device 2. Then the rotating motor 32 operates to rotate the belt rotating clamp 33, so as to transfer the cut-off zipper tape to the clip device 4 for delivery by the clip device 4. In this way, the continuous transfer of the zipper tape can be effectively realized, instead of the step-by-step intermittent transfer of the zipper tape, thereby increasing the overall operation efficiency. Figure 2 As shown, the clamping jaw 34 comprises a clamping jaw base 341, an upper clamp plate 342, a lower clamp plate 343 and a clamping jaw cylinder 344. The clamping jaw base 341 is fixedly installed on the end of the belt rotating clamp 33. The lower clamp plate 343 is fixedly installed on the clamping jaw base 341. The upper clamp plate 342 is installed on the clamping jaw base 341 in a lifting manner and is above the lower clamp plate 343. The cylinder body of the clamping jaw cylinder 344 is fixedly installed on the clamping jaw base 341. The upper clamp plate 342 is fixedly installed on the pushing rod of the clamping jaw cylinder 344. Through the above structure, the closing and separation between the upper clamp plate 342 and the lower clamp plate 343 can be realized by the action of the clamping jaw cylinder 344, so as to clamp or release the zipper tape.

[0016] Further, in order to ensure the reliability of the relative displacement between the upper clamp plate 342 and the lower clamp plate 343, the clamping jaw base 341 is fixedly provided with lifting blocks 345 on the opposite two sides. The two lifting blocks 345 are spaced apart from each other. The lower clamp plate 343 is fixedly installed on the side of the lifting block 345 away from the clamping jaw base 341. The cylinder body of the clamping jaw cylinder 344 is fixedly installed on the side of the lifting block 345 away from the lower clamp plate 343. The two sides of the upper clamp plate 342 are provided with notches. The lifting block 345 is in the notch to limit the horizontal movement of the upper clamp plate 342. In this way, the reliability of the upper clamp plate 342 during movement can be further increased. Further, a positioning cylinder 346 is fixedly installed on the clamping jaw base 341 close to the clamping jaw cylinder 344. The cylinder body of the positioning cylinder 346 is fixedly installed on the clamping jaw base 341. The pushing rod is coaxially sleeved with a positioning column 347 after penetrating through the clamping jaw base 341. The end of the positioning column 347 abuts against the lower clamp plate 343. The positioning column 347 penetrates through the upper clamp plate 342. In this way, through the positioning column 347, on the one hand, the positioning of the zipper tape can be effectively realized. On the other hand, the movement of the upper clamp plate 342 in the horizontal direction can be limited.

[0017] Further, one end of the upper clamping plate 342 and the lower clamping plate 343 is provided with a chamfer, and the two chamfers constitute a guide surface structure for guiding the zipper tape into the space between the upper clamping plate 342 and the lower clamping plate 343. The lower side of the upper clamping plate 342 is provided with a receiving groove communicating with both ends of the upper clamping plate 342. When the upper clamping plate 342 and the lower clamping plate 343 clamp the zipper tape, the teeth are in the receiving groove. Through the above structure, the clamping of the zipper tape by the upper clamping plate 342 and the lower clamping plate 343 can be effectively realized, and the damage of the teeth caused by excessive clamping force can be avoided.

[0018] In summary, the belt rotating device of the embodiment can effectively realize the continuous conveying of the zipper tape by the rotation of the two clamping jaws 34, greatly increase the conveying efficiency of the belt rotating device, and further improve the production efficiency of the invisible zipper.
