When the silk screen printing platen 3 on the frame 1 moved into place, the silk screen printing plate on the frame 1 would print the required pattern into the cloth on the silk screen printing platen 3 .

Two upper guide columns 10 and lower guide columns 11 arranged in parallel are arranged on the frame 1 , and a plane track 13 is also arranged on the frame 1 . Guide wheels 21 and rolling wheels 22 are respectively provided at the bottom of the mobile frame 2 . The middle part of the guide wheel 21 is provided with a recessed concave ring, and the concave ring of the guide wheel 21 is placed between the upper guide post 10 and the lower guide post 11 and realizes the guiding and limiting effect, then the mobile frame 2 will Move along the direction of the upper guide post 10 and the lower guide post 11. Described scroll wheel 22 is supported on the plane track 13, is supported on the frame 1 by guide wheel 21 and scroll wheel 22 like this, and guide wheel 21 has two, and scroll wheel 22 has one, realizes three-point positioning, mobile frame 2 Just can move on rack 1 smoothly.

During printing, the screen printing plate presses down on the screen printing platen 3. In order to ensure the stability of the screen printing platen 3, two support rods 8 are provided on the frame 1, and the two support rods 8 support the screen printing during silk screen printing. The rear end bottom of the platen 3 is provided with a support cylinder 9 on the frame 1, and the support cylinder 9 supports the front end bottom of the screen printing platen 3 during silk screen printing. In this way, the two support rods 8 and the support cylinder 9 support the silk screen printing platen 3 to realize the stability of the silk screen printing platen 3 .

In order to realize the positioning of the screen printing platen 3 , a front positioning column 4 and a rear positioning column 5 are respectively provided at the front and rear ends of the mobile frame 2 . The frame 1 is provided with a front locking device 6 and a rear locking device 7 which can block the front positioning column 4 and the rear positioning column 5 accordingly. Realize the positioning of the mobile frame, that is, realize the positioning of the screen printing platen.

Further, the front clamping device 6 includes a front clamping block 61 matched with the front positioning column 4, and the rear clamping device 7 includes a rear clamping block 71 matched with the rear positioning column 5. The clamping block 61 and the rear clamping block 71 block the front positioning post 4 and the rear positioning post 5 accordingly.

Furthermore, the front locking device 6 also includes a cylinder 62 hinged on the frame 1, the front block 61 is hinged on the frame 1, and the push rod of the cylinder 62 is connected to the front block 61 and push it to rotate. A front V-shaped bayonet 63 is provided on the front clamping block 61 , and the front V-shaped bayonet 63 can hold the front positioning column 4 . Under the promotion of the cylinder 62, the front V-shaped bayonet 63 of the front clamping block 61 just blocks the front positioning column 4, so that it realizes the positioning of one end of the mobile frame 2.

The rear clamping device 7 also includes a clamping block installation sleeve 72 arranged on the frame 1, the rear clamping block 71 is slidably sleeved in the clamping block installation sleeve 72, and the front end of the rear clamping block 71 is provided There is a rear V-shaped bayonet 73 .
