Four buffer springs 1103 are evenly connected between the bottom of the lower pressure plate 1102 and the inside of the bottom plate 1. The buffer springs 1103 are all sleeved on the adjacent connecting rods 1104. The front and rear sides of the top of the screen template 1101 are symmetrically connected to the lower pressure rods 13. The lower pressure rods 13 are connected to the bottom of the bottom plate 1102.

[0024] When screen printing is being performed on the bed board, the downward movement of the screen template 1101 will drive the lower pressure rod 13 to move downward. Initially, the buffer spring 1103 is in a compressed state, and the lower pressure rod 13 supports the slider 1402. After the lower pressure rod 13 moves downward, the slider 1402 is no longer subjected to force, and the lower pressure plate 1102 will drive the connecting rod 1104 to move upward under the resetting action of the buffer spring 1103, thereby pushing the bed board upward, and the pull rope 15 will also move with the connecting rod 1104, and the winding wheel 14 rotates, and the extrusion block 4 moves downward with the screen template 1101 and contacts with the center plate 12, pushing the center plate 12 to move inward to center the bed board, and the screen template 1101 moves downward and contacts with the bed board, which will squeeze the bed board downward, and under the action of the buffer spring 1103, the screen template 1101 will squeeze the bed board and the lower pressure plate 1102 to move downward, and the buffer spring 1103 compresses the bed board. Buffering, when the telescopic rod of the cylinder 3 stops extending, it can ensure that the silk screen template 1101 is in close contact with the bed board, and then the bed board is printed by the silk screen roller 11. After the printing of the bed board is completed, the telescopic rod of the cylinder 3 is retracted and reset to drive the connecting frame 8 to move upward and reset, and all the components on the connecting frame 8 move upward, and the silk screen template 1101 and the extrusion block 4 move up and no longer squeeze the bed board and the center plate 12. The center plate 12 is reset, and the bed board will drive the support column 1401 to move upward and reset under the reset action of the buffer spring 1103. When the silk screen template 1101 moves upward, it will also drive the downward pressure rod 13 to move upward. The downward pressure rod 13 pulls the slider 1402 upward through the slide groove 1301, so that the slider 1402 pulls the pull rope 15 to move outward, and the pull rope 15 pulls the support column 1401 and the bed board downward, so that the buffer spring 1103 returns to the initial compression state.
[0025] like Figure 1-2As shown, it also includes a placement box 5, a second support frame 6, a first motor 7, a rotating shaft 701, a conveyor belt 702, a push block 703 and a pulley 704. The second support frame 6 is symmetrically connected to the bottom plate 1 front and back, and a placement box 5 for placing a bed board is connected to the left side of the upper part of the bottom plate 1. The first motor 7 is installed on the right side of the front of the second support frame 6. The rotating shaft 701 is rotatably connected between the left and right sides of the two second support frames 6. The rotating shaft 701 on the right side is connected to the output shaft of the first motor 7. Pulleys 704 are fixed on both sides of the rotating shaft 701. The conveyor belt 702 is wound between the two pulleys 704 on the front side and between the two pulleys 704 on the rear side. Four push blocks 703 are evenly fixed on the two conveyor belts 702. The intermittent rotation of the conveyor belt 702 can push the bed board through the push blocks 703, so as to intermittently load the bed board.
[0026] When the bed board is being screen-printed, the bed boards can be stacked on the placement box 5, and the bottom bed board will contact the conveyor belt 702. The staff starts the first motor 7, and the output shaft of the first motor 7 rotates to drive the right-side rotating shaft 701 to rotate, and then drives the left-side rotating shaft 701 to rotate through the pulley 704 and the conveyor belt 702, and the conveyor belt 702 drives the push block 703 to rotate. The push block 703 contacts the bottom bed board and pushes the bed board to move to the right. After the bed board is pushed out of the placement box 5, the remaining bed boards in the placement box 5 are moved to the right in turn. It slides down onto the conveyor belt 702, and the push block 703 pushes the bed board to the right. After being pushed onto the lower pressure plate 1102, the output shaft of the first motor 7 will stop rotating. At this time, the cylinder 3 can be operated to screen print the bed board. After screen printing, the bed board is taken out, and the first motor 7 is started to continue operating, and the bed board is continued to be conveyed. In this way, the first motor 7 is used as a power source to intermittently convey the bed board, which can realize automatic loading of the bed board, save the trouble of manual operation, and provide convenience for the staff. After the screen printing work of the bed board is completed, the first motor 7 can be turned off.
