[0025] The top of the base 1 is fixedly connected with a fixed block 2 by screws, and a transmission shaft 13 is rotatably installed inside the fixed block 2. A driving gear 12 is fixedly sleeved on the outer circumference of the transmission shaft 13, and a driven gear 14 is sleeved on the outer circumference of the transmission shaft 13 through a one-way bearing sleeve. A first rack 10 is fixedly connected to one side of the hot pressing plate 6 by screws, and the first rack 10 is meshed with the driving gear 12. A second rack 15 is fixedly connected to one side of the placement plate 7 by screws, and the second rack 15 is meshed with the driven gear 14. The bottom of the base 1 is provided with four rectangular arrays evenly distributed The supporting foot 20 is provided with the structures such as the reset spring 17 and the placement plate 7, and the cylinder 5 is started, driving the hot pressing plate 6 to move downward to realize the laminating action. At this time, the one-way bearing will not make the driven gear 14 rotate. When the cylinder 5 contracts and moves upward, the driving gear 12 meshing with the first rack 10 drives the driven gear 14 to rotate counterclockwise, thereby driving the second rack 15 to push the placement plate 7 to move to the right. When the first rack 10 leaves the driving gear 12, the placement plate 7 is reset under the action of the reset spring 17, so as to achieve the effect of facilitating the loading and unloading of personnel.

[0026] See also Figure 1-4 Two symmetrically arranged start buttons 18 are installed on the base 1, and a display panel 19 is installed on the base 1. The start button 18 and the cylinder 5 are electrically connected to the display panel 19. Through the setting of the start button 18 and the display panel 19 and other structures, the operator must press the start buttons 18 set on both sides of the display panel 19 at the same time to start the equipment, thereby reducing accidents caused by negligence of personnel and improving the safety of the equipment.

[0027] See also Figure 1-4 A movable groove 9 is opened inside the base 1, and the placement plate 7 is slidably connected inside the movable groove 9. A cross bar 16 is welded on one side of the second rack 15, and a return spring 17 is fixedly connected between the cross bar 16 and the placement plate 7. A rotating groove is opened inside the fixed block 2, and the transmission shaft 13 is rotatably installed inside the rotating groove. A sliding groove 11 is opened inside the fixed block 2, and the first rack 10 is slidably connected inside the sliding groove 11.

[0028] The specific implementation process of the utility model is as follows: when using this device to coat the material with an electromagnetic anti-shielding film, first place the material inside the groove 8, then the start button 18 will start the cylinder 5 to drive the hot pressing plate 6 to move downward, and in the process of moving downward, it will drive the driving gear 12 to rotate clockwise to achieve the coating action. It should be noted that the driven gear 14 is set on the transmission shaft 13 through a one-way bearing sleeve, so when the first rack 10 moves downward and meshes with the driving gear, it will not drive the driven gear 14 to rotate;

[0029] Furthermore, when the laminating operation is completed and the material taking operation is required, it is only necessary to start the cylinder 5 to drive the hot pressing plate 6 to move upward, which will drive the driving gear 12 to rotate counterclockwise, and the driving gear 12 drives the driven gear 14 to rotate accordingly, and the driven gear 14 finally drives the second rack 15 to move rightward, and pushes the placement plate 7 outward along the direction of the movable groove 9, so as to achieve the effect of facilitating loading and unloading. After the loading and unloading is completed, the cylinder 5 is continued to be started to contract until the first rack 10 is separated from the driving gear 12. At this time, the second rack 15 will reset the placement plate 7 due to the action of the reset spring 17, so as to facilitate the next operation;

[0030] Finally, by providing two start buttons 18 on both sides of the display panel 19 that need to be pressed simultaneously to start the cylinder 5, accidents caused by negligence of personnel can be effectively reduced, thereby improving the safety of the equipment.
