[0021] In this embodiment, the wheels 2 are universal wheels.

[0022] In this embodiment, the connecting component includes a fixing groove 14, fixing holes 15, fixing rods 16, sliding plates 17 and a sliding component. The fixing groove 14 is opened at the top end of the connecting plate 6, two fixing holes 15 are respectively opened at the front and rear sides of the inner cavity of the fixing groove 14, two fixing rods 16 are respectively detachably inserted into the inner cavities of the two fixing holes 15, two sliding plates 17 are respectively arranged at one ends of the two fixing rods 16 close to each other, and the sliding component is arranged at the top end of the inner cavity of the casing 5 and fixedly connected to the two sliding plates 17.

[0023] In this embodiment, the sliding assembly includes a lead screw 8, a knob 9, a slider 10, a connecting rod 13 and a limiting assembly. One end of the lead screw 8 is rotatably connected to the rear side of the inner cavity of the machine housing 5 through a bearing, and the other end of the lead screw 8 extends to the front end of the machine housing 5 and is fixedly connected to the knob 9. Two sliders 10 are respectively screwed on the front and rear sides of the outer wall of the lead screw 8. Two connecting rods 13 are respectively arranged at the bottom ends of the two sliders 10 and are respectively fixedly connected to the top ends of the two sliding plates 17. The limiting assembly is arranged at the top end of the inner cavity of the machine housing 5 and is fixedly connected to the two sliders 10. Insert the connecting plate 6 into the inner cavity of the machine housing 5, so that the sliding plate 17 and the fixing rod 16 are inserted into the inner cavity of the fixing groove 14 and aligned with the fixing hole 15. Rotate the knob 9, so that the knob 9 drives the lead screw 8 to rotate, and then relative thread rotation forces are generated on the opposite threads on the left and right sides of the outer wall of the lead screw 8, so that the two sliders 10 slide simultaneously towards the front and rear ends of the lead screw 8 under the limiting action of the limiting groove 11 and the limiting block 12, so that the two connecting rods 13 respectively drive the two sliding plates 17 and the two fixing rods 16 to slide simultaneously towards the front and rear sides of the inner cavity of the fixing groove 14 and are respectively inserted into the inner cavities of the two fixing holes 15. Under the combined action of the fixing rod 16 and the fixing hole 15, the fixing of the connecting plate 6 can be realized, and then the installation of the squeegee 7 can be realized. The operation is simple and the use is convenient, solving the problem that the existing screen printing machine 1 is not convenient for disassembling and replacing the squeegee 7 during actual use, which takes a lot of time and the operation is complicated and troublesome.

[0024] In this embodiment, the limiting assembly includes a limiting groove 11 and a limiting block 12. The limiting groove 11 is opened at the top end of the inner cavity of the machine housing 5.

Insert the connecting plate 6 into the inner cavity of the machine shell 5, insert the sliding plate 17 and the fixing rod 16 into the inner cavity of the fixing groove 14 and align them with the fixing holes 15. Rotate the knob 9, so that the knob 9 drives the screw rod 8 to rotate. Then, relative screw rotation forces are generated on the left and right sides of the outer wall of the screw rod 8, causing the two sliders 10 to slide towards the front and rear ends of the screw rod 8 simultaneously under the limiting action of the limiting groove 11 and the limiting block 12. Make the two connecting rods 13 drive the two sliding plates 17 and the two fixing rods 16 to slide towards the front and rear sides of the inner cavity of the fixing groove 14 respectively and insert into the inner cavities of the two fixing holes 15. Under the combined action of the fixing rod 16 and the fixing hole 15, the fixing of the connecting plate 6 can be realized, and then the installation of the squeegee 7 can be realized.
