[0026] The working assembly includes a cylinder 2, the surface of the base 1 is fixedly connected with the cylinder 2, the output end of the cylinder 2 is fixedly connected with a fixed rod 3, the outer wall of the fixed rod 3 is fixedly connected with a rotating block 4, the interior of the rotating block 4 is fixedly connected with a rotating rod 5, the exterior of the rotating block 4 is rotatably connected with a first connecting rod 6, and the exterior of the rotating block 4 is rotatably connected with a second connecting rod 7;

[0027] The pressing assembly includes a pressing head 8 , the top end of the first connecting rod 6 is rotatably connected to the pressing head 8 , and the outside of the pressing head 8 is rotatably connected to a connecting piece 9 .

[0028] Among them, Figure 2-3 As shown, the rotating block 4 forms a rotating structure through the fixed rod 3, the cylinder 2 and the rotating rod 5. The rotating block 4 has a triangular appearance, which is conducive to the cylinder 2 to expand the rotating state of the rotating block 4 and further control the subsequent operations.

[0029] Among them, Figure 2-3 As shown, the pressure head 8 forms a rotating structure through the first connecting rod 6 and the connecting member 9, which is conducive to the pressure head 8 to press or loosen the rubber sheet when the rotating block 4 drives the first connecting rod 6 to rotate in the connecting member 9.

[0030] Among them, Figure 2-3 As shown, four groups of pressing heads 8 and connecting members 9 are provided, and the positions of the four groups of pressing heads 8 and connecting members 9 are equidistantly distributed about the midpoint of the rotating rod 5, which is beneficial for setting the four groups of pressing heads 8 and connecting members 9 to evenly press the rubber sheet in four directions, avoiding the problem of some parts failing to fit due to uneven force.

[0031] Example 2

[0032] like Figure 1 and Figure 4 As shown, a motor 10 is fixedly connected inside the base 1, a gear 11 is fixedly connected to the output end of the motor 10, a rack 12 is meshingly connected to the outer wall of the gear 11, a slide rail 13 is fixedly connected to one end of the rack 12, a slider 14 is slidably connected to the outer wall of the slide rail 13, a movable plate 15 is fixedly connected to the top of the slider 14, and a fixed plate 16 is slidably connected to the outer wall of the movable plate 15.

[0033] Among them, Figure 4 As shown, the gear 11 forms a rotating structure through the motor 10 and the rack 12, and the movable plate 15 forms a sliding structure through the slider 14 and the fixed plate 16, which is beneficial for the motor 10 to control the rotating state of the gear 11, and further control the sliding state of the movable plate 15 through the rack 12, so that the movable plate 15 and the fixed plate 16 cooperate with each other for adjustment.

[0034] Among them, Figure 4 As shown, two groups of racks 12, slide rails 13, sliders 14 and movable plates 15 are provided, and the positional relationship of the two groups of racks 12, slide rails 13, sliders 14 and movable plates 15 is symmetrical about the midpoint of the gear 11, which is beneficial to the provision of two groups of racks 12, slide rails 13, sliders 14 and movable plates 15 so as to make the sliding structure more stable, thereby allowing the movable plate 15 to slide smoothly.

[0035] During use: first, the cylinder 2 pushes the fixed rod 3, so that it drives the rotating block 4 to rotate on the rotating rod 5, and drives the first connecting rod 6 to rotate, so that it pushes or pulls a group of pressure heads 8, so that the pressure heads 8 rotate through the connecting piece 9 and tighten or loosen the rubber sheet. At the same time, the rotating block 4 will drive the second connecting rod 7 to rotate, so that the second connecting rod 7 drives another group of pressure heads 8 to operate synchronously. When the pressure heads 8 are parallel to the base 1, the rubber sheet will be tightened, otherwise it will be loosened when they are not parallel. Therefore, the function of tightening or loosening the pressure heads 8 can be controlled by operating the rotating block 4.

[0036] Finally, the motor 10 drives the gear 11 to rotate, so that it drives the racks 12 on both sides to slide on the base 1, and drives the slide rails 13 to slide synchronously, so that the movable plate 15 is driven by the slider 14 to slide in the fixed plate 16. When the movable plates 15 on both sides slide in the fixed plate 16, the area inside the plate can be expanded or reduced, so that rubber sheets of different sizes can be loaded and then pressed, thereby expanding the application range of the pressing device.
