[0026] The present invention is provided with a displacement structure 5 to drive the positioning structure 6 and cooperate with the pressure plate structure 7, so that two layers of fluororubber and one layer of woven cloth form a sandwich structure. When in use, the three layers of the pressure material in the form of a band are placed on the three-layer rubber plate 607 in sequence from bottom to top in the order of fluororubber-woven cloth-fluororubber, and the outer surface holes are put on the corresponding positioning protrusions 608. Then, the connecting lasso 606 is removed from the hanging rod 602, and the rubber plate 607 is manually pressed to position the pressure material. Then, the hydraulic pump 11 is started to drive the hydraulic telescopic rod 10 to descend, so that the pressure plate structure 7 is pressed downward, and the first pressing block 702 first contacts the pressure material and presses the middle part of the pressure material. Then, the pressure plate bodies 701 on both sides are pressed downward, and then the first pressing block 702 is driven to press the three layers of the pressure material into shape.

The area and volume of the positioning protrusion 608 located in the middle are larger than the area and volume of the positioning protrusions 608 located at the bottom and at the top.

[0028] When placing the pressing material, the present invention hangs the connecting lasso 606 on the hanging rod 602. Since the connecting rope 605 is provided between the inlay pieces 604, the three inlay pieces 604 slide along the positioning slide groove 603 and open the spacing, so that the pressing material can be smoothly placed on the rubber plate 607 at the other end of the inlay piece 604, and the positioning protrusion 608 corresponds to the surface hole on the pressing material. The area and volume of the positioning protrusion 608 located in the middle are larger than the area and volume of the positioning protrusions 608 located at the bottom and the top because the finished watchband is a sandwich structure, the pressing material area of ​​the middle layer is smaller than the pressing material area on both sides, but its surface hole area is larger than the surface hole area of ​​the pressing materials on both sides.

[0029] Refer to the instruction manual Figure 1 and 4 The material of the rubber sheet 607 is a rubber material modified by glass fiber, which can enhance the anti-pulling and high temperature resistance performance of the rubber sheet 607.

[0030] Refer to the instruction manual Figure 2 , 4 And 5, the displacement structure 5 includes two clamping plates 501, between which a roller 502 and a gear roller 503 are rotatably connected, a transmission belt 504 is sleeved between the roller 502 and the gear roller 503, and a support frame 505 is installed on the inner side of the transmission belt 504, and the support frame 505 is slidably fitted with the top end and the bottom end of the inner side of the transmission belt 504, and the top end of the support frame 505 is fixedly connected to the bottom end of the top seat 4.

[0031] The present invention arranges the support frame 505 to abut against the top end and the bottom end of the inner side of the transmission belt 504 so that the transmission belt 504 moves smoothly during the transmission process.

[0032] Refer to the instruction manual Figure 4-5 The bottom end of the inner wall of the support frame 505 is slidably connected with a mounting frame 506, the bottom end of the mounting frame 506 is fixedly connected to the bottom end of the transmission belt 504, the top of the mounting frame 506 is provided with an adjusting slot 507, the inside of the mounting frame 506 is snap-connected with a connecting frame 508, the top of the connecting frame 508 is fixedly connected with an adjusting screw, the top of the adjusting screw is inserted through the adjusting slot 507, and the end of the adjusting screw is threadedly sleeved with an adjusting nut, and one side of the bottom end of the connecting frame 508 is fixedly connected to one end of the corresponding positioning plate 601.

[0033] The present invention can slide the adjustment screw to make the connecting frame 508 slide in the mounting frame 506, adjust its own position, and drive the positioning structure 6 to follow the adjustment position to adapt to different watch strap pressings, and fix the position by adjusting the nut so that the connecting frame 508 itself can move together with the mounting frame 506.

[0034] Refer to the instruction manual Figure 1-2 The pressure plate structure 7 includes a pressure plate body 701, a first pressure block 702 is slidably connected to the middle of the bottom end of the pressure plate body 701, a sliding rod 703 is fixedly connected to the top of the first pressure block 702, the top of the sliding rod 703 penetrates the top of the pressure plate body 701 and extends to the outside, and pressure grooves 704 are fixedly opened on both sides of the pressure plate body 701.

[0035] The pressing plate body 701 and the pre-pressing block 702 of the present invention are both internally installed with heating structures for heating the pressing plate body 701 and the pre-pressing block 702 when necessary.

[0036] Refer to the instruction manual Figure 1-2 One side of the tooth plate 8 is meshedly connected with the adjacent gear roller 503 , and the bottom end of the other side of the tooth plate 8 is fixedly connected with a clamping strip 801 , which matches the adjacent pressing groove 704 .

[0037] In the process of the pressing plate body 701 descending, the pressing grooves 704 on both sides hook the card strips 801, drive the toothed plate 8 to move downward together, compress the spring telescopic rod group 9, and the toothed plate 8 moves downward to rotate the gear roller 503, thereby driving the transmission belt 504 to transmit, and the transmission belt 504 drives the mounting frame 506 to move along the support frame frame 505 in the direction away from the pressing plate structure 7, and the mounting frame 506 drives the connecting frame 508, thereby causing the positioning structure 6 to move in the direction away from the pressing plate structure 7, cooperating with the pressing process of the pressing plate structure 7. Therefore, when the pressing plate structure 7 is pressed downward, the toothed plate 8 moves downward to rotate the gear roller 503, thereby driving the transmission belt 504 to transmit, and the transmission belt 504 drives the mounting frame 506 to move along the support frame frame 505 in the direction away from the pressing plate structure 7. When the structure 7 moves downward, the positioned rubber plate 607 first escapes from the pressing material, and then the first pressing block 702 fixes the middle part of the pressing material, then the positioning structure 6 completely escapes from the base 1, and finally the pressing plate body 701 presses the two ends of the pressing material, driving the first pressing block 702 to press the pressing material together. In the process of the positioning structure 6 escaping from the pressing material, the friction force on the pressing material is symmetrical, and the size of the positioning protrusion 608 and the surface hole are matched. Therefore, when the pressing material is pressed, the hole positions of the surface holes correspond to each other, forming a sandwich structure, and no trace of the middle woven cloth can be seen from the surface holes;

[0038] By reasonably setting the connecting frame 508 and the pressure plate structure 7, such as setting the bottom end of the connecting frame 508 to a telescopic structure and thickening the pressure plate body 701, the height of the first pressing block 702 protruding from the pressure plate body 701 can be greater than the height of the positioning structure 6. In the pressing process, the first pressing block 702 can first fix the middle part of the pressing material, and then the positioning structures 6 on both sides can be pulled out of the pressing material under the pull of the connecting frame 508 stretched to the limit.

[0039] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
