The limit rod 36 is arranged relative to the vertical slider 38, which can prevent the vertical guide rail 37 from separating from the vertical slider 38 and ensure the stability of the overall operation.

[0044] In one embodiment of the utility model, the driving assembly includes a driving plate 7, the driving plate 7 is slidably mounted on the base 21, a lifting slope 9 is arranged on the driving plate 7, a guide component 8 is arranged at the bottom of the frame 3, the guide component 8 includes a guide frame 81, a roller 82 is arranged on the guide frame 81, the roller 82 is a cam structure, the roller 82 is slidably mounted on the lifting slope 9, the driving plate 7 moves to drive the roller 82 to move along the lifting slope 9 so that the frame 3 performs a lifting movement.

The driving plate 7 moves to drive the roller 82 to move along the lifting slope 9, thereby completing the lifting and lowering movement of the pressure maintaining head 5 on the frame 3, completing the two-way pressure maintaining of the product, and adopting a cam driving mechanism in both directions, which also makes the entire module smaller and more compact, with high efficiency and easy operation.

[0046] In one embodiment of the utility model, the lifting slope 9 includes an ascending plane 91 and a descending plane 92, and the ascending plane 91 and the descending plane 92 are connected by an inclined plane.

[0047] Specifically, the driving plate 7 moves to drive the roller 82 to move along the lifting slope 9, so that the roller 82 moves from the rising plane 91 to the descending plane 92. Since the horizontal height of the rising plane 91 is higher than the horizontal height of the descending plane 92, under the reaction force of the vertical spring 34, the frame 3 moves downward, driving the pressure maintaining head 5 on the pressure maintaining plate 4 to vertically maintain pressure on the product. The magnet is magnetically connected to the driving plate 7, so that it can locate the position of the driving plate 7, avoid the movement of the driving plate 7 causing the equipment to get stuck, and ensure the stable operation of the equipment.

The reaction force of the return spring lifts the buckle 73 so that it is stuck on the fixed block 42, so that the drive plate 7 is self-locking and cannot move toward the adsorption block 76, thereby realizing two-way pressure-maintaining self-locking of the product.

[0050] In an embodiment of the utility model, a slide rail 77 is provided on the base 21 , a sliding block is provided on the driving plate 7 , the sliding block is slidably arranged on the slide rail 77 , and a driving handle 75 is provided on the driving plate 7 .

The manual mode is adopted, with a compact structure, low cost and high efficiency.

[0052] Usage process

[0053] The handle 62 is turned to make the cam surface 61 on the guide cam 6 slide on the frame 3, so that the material blocking groove 64 is clamped on the material blocking block 63. Driven by the reaction force of the transverse spring 43, the guide rod 41 moves along the guide hole, so that the pressure maintaining head 5 on the pressure maintaining plate 4 moves laterally to connect with the product pressure maintaining. At this time, the buckle 73 is set in the guide groove 421 at the bottom of the fixed block 42. Pulling the driving handle 75 drives the driving plate 7 to move in the direction away from the adsorption block 76. The roller 82 is slidably arranged on the lifting inclined surface 9. The movement of the driving plate 7 drives the roller 82 to move along the lifting inclined surface 9, so that the roller 82 is The rising plane 91 moves to the descending plane 92. Since the horizontal height of the rising plane 91 is higher than the horizontal height of the descending plane 92, under the reaction force of the vertical spring 34, the frame 3 moves downward, driving the pressure-maintaining head 5 on the pressure-maintaining plate 4 to vertically maintain pressure on the product. At the same time, during the movement of the driving plate 7, the buckle 73 compresses the return spring in the guide groove 421 and makes it slide out of the guide groove 421. Under the reaction force of the return spring, the buckle 73 is lifted and stuck on the fixed block 42, so that the driving plate 7 is self-locking and cannot move toward the adsorption block 76, thereby realizing two-way pressure-maintaining self-locking of the product.
