[0030] As shown in Figure 4 , a plurality of connecting rods 20 are distributed around the axis of the hydraulic cylinder 13 and arranged on the side of the output block 15 close to the hydraulic cylinder 13, and the press roller 22 and the connecting rod 20 are further fixedly connected through the first reset spring 12.

[0031] As shown in Figures 1 to 2 , the lower end of the connecting plate 14 is fixedly provided with a printing die 19 for printing, the extension length of the hydraulic cylinder 13 is greater than the length of the pressing block 18, the length of the pressing block 18 is greater than the length of the connecting rod 20, the depth of the sliding groove 16 is greater than the length of the pressing block 18, the connecting plate 14 on the left side of the output block 15 is provided with a plurality of side surfaces corresponding to the connecting rod 20, and the connecting rod 20 is fixedly connected with the corresponding side surface of the connecting plate 14 through the second reset spring 21.

[0032] Firstly, the fabric is placed on the bottom wall inside the shell 11, and the positioning position of the fabric is aligned with the opening edge of the shell 11, so that the printing on the fabric is ensured to be in the right position. The hydraulic cylinder 13 is connected with the external hydraulic system and drives the connecting plate 14 to move downward. The connecting plate 14 drives the output block 15 and the pressing block 18 to move downward and press the positioning point of the fabric, so that the accuracy of the printing position of the fabric is ensured. The connecting plate 14 continues to move downward and drives the pressing roller 22 to contact the fabric. One end of the connecting rod 20 is driven by the connecting plate 14 to move downward, and the pressing roller 22 at the other end of the connecting rod 20 is limited by the bottom wall inside the shell 11 to roll away from the pressing block 18, so as to flatten the surface of the fabric.
