A rotating assembly for driving the second clamping frame 31 to adjust is also arranged on the top of the sliding seat 29. The rotating assembly includes a rotating motor 36 installed on the top of the sliding seat 29. The output end of the rotating motor 36 is connected with a first gear 37. The first gear 37 is engaged with a second gear 38 arranged on the transmission shaft 30 rotatably installed on the top of the sliding seat 29. More specifically, when embroidering the cloth, first place the cloth on the two lower clamping blocks 32 arranged on one side of the second clamping frame 31. Drive the second electric cylinder 35 installed on the top to drive the U-shaped upper clamping block 34 connected to one end to move downward along the sliding rod 33 to clamp the cloth. Then drive the rotating motor 36 installed on the top of the sliding seat 29 to make the first gear 37 connected to the output end rotate to drive the second gear 38 arranged on the transmission shaft 30 to rotate. Thus, the transmission shaft 30 rotates to drive the second clamping frame 31 to rotate 90° to align with the placement frame 5 on the top of the moving table 4. Then drive the second driving motor 28 fixed at one end of the support plate 26 to make the lead screw 27 connected to one end rotate to drive the sliding seat 29 to move along the through groove, and make the cloth clamped on the second clamping frame 31 move onto the placement frame 5, thereby completing the automatic feeding work. When the embroidery work is completed, similarly, drive the lead screw 27 to rotate through the second driving motor 28, so that the lower clamping blocks 32 and the U-shaped upper clamping block 34 move onto the placement frame 5 on the top of the moving table 4 to clamp and take out the embroidered cloth. Then drive the rotating motor 36 to drive the second clamping frame 31 to rotate, thereby completing the automatic material taking work, making the operation more convenient.

[0026] Reference Figure 1, the pushing mechanism includes a fixed seat 39 installed at the top of the processing table 1 near one end edge. A motor-driven hydraulic rod 40 is fixedly installed on the top of the fixed seat 39. One end of the motor-driven hydraulic rod 40 is connected to a U-shaped connecting frame 41.

Sliding seats 42 are further provided at the bottoms of the left and right ends of the moving table 4. The sliding seats 42 are slidably installed on two symmetrically arranged slide rails 43 provided on the top of the processing table 1. More specifically, by driving the motor-driven hydraulic rod 40 installed on the top of the fixed seat 39 on the top of the processing table 1, the U-shaped connecting frame 41 connected to one end of the motor-driven hydraulic rod 40 drives the moving table 4 to move along the slide rails 43 provided on the top of the processing table 1 through the sliding seats 42 provided at both ends to the bottom of the U-shaped fixing frame 2, so as to facilitate embroidery processing of the fabric on the top of the moving table 4.

[0027] The implementation principle of a cloth clamping mechanism for an embroidery machine in an embodiment of the present invention is as follows: When embroidering the cloth, first place the cloth on two lower clamping blocks 32 provided on one side of the second clamping frame 31. Drive the second electric cylinder 35 to drive the U-shaped upper clamping block 34 to move downward along the sliding rod 33 to clamp the cloth. Drive the rotating motor 36 to rotate the first gear 37 to drive the second gear 38 to rotate, so that the transmission shaft 30 rotates to drive the second clamping frame 31 to rotate 90° to align with the placement frame 5 on the top of the moving table 4. Then drive the second driving motor 28 to drive the lead screw 27 to rotate, so that the sliding seat 29 moves along the through groove and drives the cloth clamped on the second clamping frame 31 to move onto the placement frame 5, thus completing the automatic feeding work. At this time, drive two first electric cylinders 11 to drive the clamping plates 12 connected to the bottom to clamp both ends of the cloth. Then drive the first driving motor 6 fixedly installed at one end of the moving table 4 to rotate the bidirectional lead screw 7 connected to one end to drive the two movable seats 8 to move towards both ends, so that the L-shaped connecting blocks 9 connected to the tops of the two movable seats 8 move along the sliding grooves opened on the top of the moving table 4 towards both ends, so that the L-shaped connecting blocks 9 drive the first clamping frame 10 connected to one end to move towards both ends, thereby tightening the clamped cloth towards both ends, making the cloth straight on the top of the placement frame 5. At the same time, drive the electric telescopic rods 16 on the tops of the two fixing plates 15 to drive the connecting plates 17 connected to one end to move downward, so that the sliding blocks 18 connected to both ends of the connecting plates 17 move downward along the fixing rods 14 and squeeze the first spring 20. While the sliding blocks 18 move downward, they drive the movable frames 19 connected to one end to move downward, so that the movable rods 23 in the connecting seats 22 at both ends of the mounting seats 21 provided on both side walls of the movable frames 19 rotate towards both sides, so that the leveling rollers 25 rotatably installed at one ends of the movable rods 23 roll towards both sides to level the straightened cloth and keep it flat, improving the quality of embroidery. Then drive the electric hydraulic rod 40 to drive the U-shaped connecting frame 41 connected to one end to drive the moving table 4 to move to the bottom of the embroidery machine body installed on the U-shaped fixing frame 2 through the sliding seats 42 provided at both bottoms of the two ends along the slide rail 43, so as to perform embroidery processing on the cloth on the top of the moving table 4. When the embroidery work is completed, similarly, drive the second driving motor 28 to drive the lead screw 27 to rotate, so that the second clamping frame 31 drives the lower clamping blocks 32 and the U-shaped upper clamping block 34 to move to the top of the moving table 4 and the placement frame 5 to clamp and take out the embroidered cloth. Then drive the rotating motor 36 to drive the second clamping frame 31 to rotate, thus completing the automatic material taking work and making the operation more convenient.
