The operation is simple, and it is fixed by adjusting the upper and lower slide rails, with high stability and improved work efficiency.

[0028] In one embodiment, the adjusting wheel group 3 includes two sets of adjusting wheel groups 3 arranged side by side. The two sets of adjusting wheel groups 3 are respectively arranged on both sides of the fixing plate of the plate-making device 16. The linear driving motor is installed on the adjusting wheel group 3 on the opposite side of the lifting clamping groove 2, which can reduce the pressure on one side of the lifting clamping groove 2 and improve the stability during the lifting process.

[0029] In one embodiment, a lifting slide rail 8 for the up and down sliding of the lifting clamping groove 2 is provided inside the lifting clamping groove 2, and a guiding notch 9 for the chain 4 to pass through is provided on the adjusting wheel group 3. Specifically, the adjusting wheel group 3 is fixed on the plate-making device 16 by a support seat. The middle of the support seat is a sprocket, and the upper surface of the support seat exceeds the height of the sprocket. A guiding notch 9 is formed between the two support seats, so that the chain 4 is transmitted in the guiding notch 9, avoiding the chain 4 falling off during the lifting process and improving the stability and safety.

[0030] Among them, the counterweight assembly includes a counterweight block 5 connected to the end of the chain 4. A fixed counterweight sleeve 6 is provided outside the counterweight block 5.

The driving end of the cylinder 12 horizontally presses against the product, further improving the stability of the product during the printing process.

[0032] In one embodiment, a limiting plate 13 is provided at the end of the feeding plate in the receiving groove 10 of both the screen frame fixing groove 1 and the lifting clamping groove 2. The limiting plate 13 realizes the positioning of the product when it is conveyed into the printing device.

[0033] In one embodiment, in order to ensure that the lifting clamping groove 2 stably clamps the product in the receiving groove 10 during the descending process, a guiding plate 14 is inclinedly arranged on the partition plate 11 of the lifting clamping groove 2, and the inclined surface of the guiding plate 14 faces the side of the air cylinder 12.

[0034] In one embodiment, in order to ensure the stability after the lifting clamping groove 2 clamps and prevent deviation during the up and down movement, a drag chain 15 is provided at one end of the lifting clamping groove 2, and the other end of the drag chain 15 is fixed on the plate-making device 16.
