[0031] Reference Figure 2 and Figure 4 , and refer to Figure 5 The flat pressing assembly 37 includes a pressing roller 371, a screw rod 372, a motor 373, a first pulley 374, a second pulley 375, and a belt 376. The bottom surface of the upper pressing plate 34 is symmetrically provided with slide grooves 341 at both ends along the width direction thereof, and the slide grooves 341 are arranged along the length direction of the upper pressing plate 34. There are two screw rods 372, and the two screw rods 372 correspond to the two slide grooves 341 one by one. The screw rod 372 is arranged in the slide groove 341 along the length direction of the slide groove 341, and one end of the screw rod 372 is rotatably connected to the side wall of the upper pressing plate 34, and the other end passes through the side wall of the upper pressing plate 34 and is rotatably connected thereto. Slide blocks 38 are respectively arranged on the two screw rods 372, and the slide blocks 38 are threadedly connected to the screw rods 372. The slide groove 341 is adapted to the slide block 38, and the slide block 38 is slidably connected to the slide groove 341.

The diameter of the pressure roller 371 is greater than the height of the slider 38, so that when the outer peripheral surface of the pressure roller 371 can touch the lower pressure plate 35, the slider 38 will not touch the lower pressure plate 35, so that the pressure roller 371 can roll on the top surface of the lower pressure plate 35. The upper pressure plate 34 is vertically fixed with a second mounting plate 342 on the side wall close to the limiting mechanism 4, and the motor 373 is fixed on the second mounting plate 342, and the output shaft of the motor 373 is fixedly connected to the end of the screw rod 372 near the second mounting plate 342 that passes through the upper pressure plate 34. The first pulley 374 is sleeved on the end of the screw rod 372 near the motor 373 that passes through the side wall of the upper pressure plate 34, and is fixedly connected thereto. The second pulley 375 is sleeved on the end of the screw 372 away from the motor 373 and passing through the side wall of the upper pressing plate 34, and is fixedly connected thereto. The belt 376 is sleeved on the first pulley 374 and the second pulley 375. The side wall of the lower pressing plate 35 is fixedly provided with a sensor 351 and a processor 352, and the sensor 351 is electrically connected to the processor 352, and the processor 352 is electrically connected to the motor 373 and the cylinder 22.

[0032] When in use, place the whiteboard on the fixing mechanism 5 and start the cylinder 22. The cylinder 22 can drive the upper pressing plate 34 to move, and then drive the lower pressing plate 35 to move. When the lower pressing plate 35 touches the whiteboard, due to the action of the cylinder 22, the upper pressing plate 34 will continue to descend, and then the spring 363 will be compressed, and the piston rod 362 will extend into the sleeve 361, which will give pressure to the lower pressing plate 35 again, and continue to press the whiteboard. When the sensor 351 senses that the pressure roller 371 touches the lower pressing plate 35, it will send the signal The signal is transmitted to the processor 352, and the processor 352 stops the cylinder 22 and starts the motor 373, driving the screw 372 fixed to the motor 373 to rotate. Due to the connection of the belt 376, the other screw 372 can also rotate. Due to the limiting effect of the slide groove 341, the slider 38 can only move along the slide groove 341, so that the pressure roller 371 rolls along the length direction of the lower pressure plate 35, which gives pressure to the whiteboard again, making the pressure on the whiteboard more uniform, thereby achieving the pressing of the whiteboard.

[0033] Reference Figure 1 and Figure 3 , there are two groups of limit mechanisms 4, and the two groups of limit mechanisms 4 are symmetrically arranged at both ends of the bracket 1 along its length direction. The limit mechanism 4 includes a rack 41, a first gear 42, and a second gear 43. The rack 41 is arranged along the height direction of the bracket 1 and is fixed on the side wall of the bracket 1 along its width direction. The first gear 42 is arranged on the rack 41 on one side of the upper pressure plate 34, and the first gear 42 is meshed with the rack 41.

A second limiting rod 45 is fixedly provided on the side wall of the lower pressing plate 35 close to the rack 41 . The second limiting rod 45 is arranged along the length direction of the bracket 1 , and one end of the second limiting rod 45 away from the lower pressing plate 35 is rotatably connected to the second gear 43 .

[0034] When in use, since the first gear 42 is meshed with the rack 41 and the second gear 43 is meshed with the rack 41 , the upper pressing plate 34 and the lower pressing plate 35 can only be reduced from tipping over, thereby facilitating the pressing of the whiteboard.

[0035] Reference Figure 1 and Figure 2 The fixing mechanism 5 includes an anti-skid pad 51 and a clip 52. The anti-skid pad 51 is fixed on the bottom surface of the bracket 1 below the lower pressing plate 35. There are four clips 52, and the four clips 52 are respectively fixed at the four end corners of the anti-skid pad 51. When in use, the whiteboard is placed on the anti-skid pad 51 and clamped with the clips 52 to fix the whiteboard.

[0036] The implementation principle of the embodiment of the present application is as follows: the operator first places the whiteboard on the anti-slip mat 51, fixes it with a clip 52, and then starts the cylinder 22. The cylinder 22 will drive the pressing plate mechanism 3 to press down the whiteboard. When the lower pressing plate 35 contacts the whiteboard, the upper pressing plate 34 will continue to descend, and then the flat pressing assembly 37 will be started to press down the whiteboard again. By pressing down the whiteboard multiple times and making the pressure more uniform, the whiteboard can be pressed.

[0037] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
