[0027] Reference Figure 3 A lifting column 13 is fixedly connected to the lower surface of the workbench 1, and a housing 14 is slidably connected to the outer wall of the lifting column 13; a spring 15 is arranged inside the housing 14, and the outer wall of the lifting column 13 is slidably connected to the inner wall of the spring 15; a pressure block 16 is fixedly connected to the outer wall of the lifting column 13, and one end of the spring 15 is fixedly connected to the upper surface of the pressure block 16; a motor 17 is fixedly connected to the inside of the housing 14, and a rotating column 18 is fixedly connected to the output end of the motor 17;

[0028] Specifically, turning on the motor 17 will drive the rotating column 18 to rotate, and the lifting column 13 will drive the pressure block 16 to compress the spring 15. The lifting column 13 is lifted and lowered to achieve the effect of driving the workbench 1 to lift and lower.

[0029] Reference Figure 3 The outer wall of the rotating column 18 is fixedly connected to the lifting frame 19, and the inner wall of the lifting column 13 is rotatably connected to the ball 20; the outer wall of the ball 20 is rotatably connected to the upper surface of the lifting frame 19, and the lower surface of the shell 14 is provided with a supporting assembly; the supporting assembly includes a support plate 21, the upper surface of the support plate 21 is fixedly connected to the upper surface of the shell 14, the lower surface of the support plate 21 is fixedly connected to the bottom plate 22, and the outer wall of the rotating column 18 is rotatably connected to the inner wall of the bottom plate 22;

[0031] Working principle: When the device is needed, first turn on the second hydraulic press 5 on the upper surface of the workbench 1, and the second hydraulic press 5 starts to run. When the second hydraulic press 5 starts to run, it will pull the round shaft 6 at its output end to move. When the outer wall of the round shaft 6 moves on the inner wall of the connecting frame 7, it will drive the connecting plate 8 of its outer wall to move. When the connecting plate 8 moves, it will drive the connecting block 9 of its outer wall to rotate. When the outer wall of the connecting block 9 rotates on the outer wall of the connecting plate 8, it will drive the linkage plate 10 of its outer wall to rotate. When the inner wall of the linkage plate 10 is on the connecting frame, When the outer wall of 7 rotates, it will drive the clamping hand 11 on its inner wall to clamp the mask, and then the first hydraulic press 3 inside the pillar 2 will be turned on.

When the workbench 1 needs to be folded, When the lifting column 13 is lifted, the motor 17 is turned on. When the motor 17 is running, the rotating column 18 at its output end is driven to rotate. When the outer wall of the rotating column 18 rotates on the inner wall of the shell 14 and the bottom plate 22, the lifting frame 19 on the outer wall is driven to rotate. When the lifting frame 19 rotates, the ball 20 on its upper surface is driven to rotate. When the outer wall of the ball 20 rotates on the upper surface of the lifting frame 19, the lifting column 13 is driven to lift. When the lifting column 13 is lifted, the pressure block 16 on the outer wall is driven to lift. When the pressure block 16 is lifted, The spring 15 on its upper surface is compressed, and the support plate 21 supports the shell 14 above the bottom plate 22. Finally, the lifting column 13 is lifted and lowered to drive the workbench 1 to lift and lower. This not only ensures the accuracy and consistency of folding after the mask is accurately clamped and positioned on the folding equipment, but also makes it easier for operators to contact and handle the mask by adjusting the height of the equipment, thereby improving work efficiency. Finally, it can also reduce errors in the folding process through precise clamping, thereby improving the yield rate of finished mask products.
