At this time, when the circular slide plate 139 moves, the embroidery craft moves relative to the supporting circular plate 103. When the leveling scraper 113 levels the embroidery craft, the embroidery craft as a whole cannot move relative to the supporting circular plate 103.

[0038] A reset spring 149 is arranged between the L-shaped lower pressure plate 144 and the circular push plate 146. The elastic force of the reset spring 149 is always greater than the elastic force of the torsion spring between the long arm rotating plate 140 and the circular slide 139. The reset unit includes a reset gear ring 141 rotatably mounted on the circular slide 138, and a reset gear 142 is also rotatably mounted on the circular slide 138. The reset gear 142 and the reset gear ring 141 constitute a gear pair. A reset motor 147 is fixedly mounted on the lower surface of the circular slide 138, and the output shaft of the reset motor 147 is fixedly connected to the reset gear 142. A fan-shaped long strip plate 143 is fixedly mounted on the outer circumferential surface of the reset gear ring 141, and a fan-shaped short strip plate 145 is fixedly mounted on the upper end surface of the L-shaped lower pressure plate 144. The circular push plate 146 is used to adsorb the fan-shaped short strip plate 145 to move.

[0039] The closest end faces of two adjacent fan-shaped short strips 145 are on the same plane, and the projections of all the fan-shaped short strips 145 relative to the lower surface of the base plate 101 form a complete annular plate. The arc length of the fan-shaped long strip 143 is equal to the arc length of the two fan-shaped short strips 145, and the dimensions of the fan-shaped long strip 143 and the two fan-shaped short strips 145 when joined together are equal. When the fan-shaped long strip 143 is located directly above the fan-shaped short strip 145, the magnetic force between the fan-shaped short strip 145 and the fan-shaped long strip 143 is always greater than the elastic force of the reset spring 149 corresponding to the fan-shaped short strip 145, that is, when the fan-shaped long strip 143 is located directly above a certain fan-shaped short strip 145, the fan-shaped short strip 145 is located at the position closest to the fan-shaped long strip 143, and the reset spring 149 corresponding to the fan-shaped short strip 145 is compressed to the maximum deformation.

[0040] In the initial position, the support spring 148 is not compressed, the circular slide 139 is located at the farthest position from the circular slide 138, the torsion springs between the long arm rotating plate 140 and the circular slide 139 are not compressed, and the long arm rotating plates 140 are in a vertical upward state. The return springs 149 are not compressed, and the L-shaped lower pressure plate 144 is located at the farthest position from the circular slide 138, and the lower end of the L-shaped lower pressure plate 144 is in contact with the corresponding pressing inclined plate 150.

[0041] When performing circular trimming on an embroidery craft, the second adjustment slide plate 107 and the second adjustment motor 121 are started so that the axis of the circular slide plate 139 and the center line of the embroidery craft are in the same straight line, and then the pressing motor 129 is started to drive the circular slide 138 and the circular slide plate 139 to move downward synchronously, so that the lower surface of the circular slide plate 139 contacts the embroidery craft, and then the circular slide 138 is continued to be driven to move downward. At this time, the circular slide plate 139 cannot move downward further, and the circular push plate 146 moves downward relative to the circular slide plate 139, and the support spring 148 is compressed. Under the action of the reset spring 149, the L-shaped lower pressure plate 144 moves downward synchronously. The elastic force of spring 149 is always greater than the elastic force of the torsion spring between the long arm rotating plate 140 and the circular slide 139, that is, under the action of the L-shaped lower pressure plate 144, the pressing inclined plate 150 rotates relative to the corresponding rotation connection between the long arm rotating plate 140 and the circular slide 139, that is, the long arm rotating plate 140 rotates relative to the rotation connection between the long arm rotating plate 140 and the circular slide 139, and finally, under the action of the L-shaped lower pressure plate 144 and the pressing inclined plate 150, the long arm rotating plates 140 are all rotated to a horizontal state. At this time, the lower surfaces of the long arm rotating plates 140 are in contact with the upper surface of the embroidery craft, and the annular pressing of the embroidery craft is achieved under the action of multiple long arm rotating plates 140.

[0042] When the laser head 132 performs circular trimming on the embroidery craftwork, the reset motor 147 is first started to drive the reset gear 142 to rotate, so that the circular slide 138 and the fan-shaped long strip plate 143 rotate synchronously, so that the fan-shaped long strip plate 143 moves to the top of the two adjacent fan-shaped short strip plates 145, and then the fan-shaped long strip plate 143 is started, and the fan-shaped long strip plate 143 adsorbs the two fan-shaped short strip plates 145, so that the two fan-shaped short strip plates 145 move upward, and the reset spring 149 corresponding to the fan-shaped short strip plates 145 is compressed. The fan-shaped short strip 145 is directly above the fan-shaped short strip 145, which makes the fan-shaped short strip 145 move to the position closest to the fan-shaped long strip 143, and the return spring 149 corresponding to the fan-shaped short strip 145 is compressed to the maximum deformation, which makes the L-shaped lower pressure plate 144 corresponding to the fan-shaped short strip 145 move to the position closest to the fan-shaped long strip 143. The L-shaped lower pressure plate 144 contacts the corresponding pressing inclined plate 150, and under the action of the torsion spring between the long arm rotating plate 140 and the circular slide plate 139, the long arm rotating plates 140 corresponding to the two fan-shaped short strips 145 return to the vertical upward state.

[0043] Then start the height adjustment motor 128, the auxiliary motor 136, and the distance adjustment motor 137 to adjust the position of the laser head 132, so that the laser head 132 moves to the position of the fan-shaped area corresponding to the two fan-shaped short strips 145, and then start the laser head 132, and then start the auxiliary motor 136 to drive the annular rotating plate 133 to rotate, so that the laser head 132 rotates relative to the axis of the auxiliary ring frame 108, so that the laser head 132 performs circular trimming on the embroidery craft. While starting the auxiliary motor 136 to drive the laser head 132 to rotate, start the reset motor 147 to drive the circular slide 138 and the fan-shaped long strip 143 to rotate synchronously. The circular slide 138 and the annular rotating plate 133 have the same rotation direction, and at this time the angular velocities of the annular rotating plate 133 and the circular slide 138 are equal. During the gradual movement of the fan-shaped long strip 143, the fan-shaped long strip 143 gradually moves to the top of the next fan-shaped short strip 145, that is, the next fan-shaped short strip 145 gradually moves upward. At this time, the fan-shaped long strip 143 gradually moves away from the fan-shaped short strip 145 at the end, that is, the fan-shaped short strip 145 at the end gradually moves downward, and finally the next fan-shaped short strip 145 moves to the position closest to the fan-shaped long strip 143, that is, the long arm rotating plate 140 corresponding to the fan-shaped short strip 145 is rotated to a vertically upward state, that is, the moving direction of the laser head 132 is given way, so that the fan-shaped short strip 145 at the end returns to the initial position, that is, the long arm rotating plate 140 corresponding to the fan-shaped short strip 145 is rotated to a horizontal state, that is, the embroidery craft is pressed and fixed again.

[0044] Working principle: When trimming a rectangular embroidery craft, the staff will spread the embroidery craft flat on the supporting circular plate 103, and then start the positioning motor 106 and the positioning motor 2 121 to make the axis of the circular slide 139 and the center of the embroidery craft in the same straight line, and then start the pressing motor 129 to make the circular slide 139 move downward to contact the upper surface of the embroidery craft, and then start the positioning motor 106 and the positioning motor 2 121 to adjust the position of the circular slide 139. Under the action of the circular slide 139, the embroidery craft moves synchronously, and finally the center line of the embroidery craft moves to be in the same straight line with the axis of the supporting circular plate 103, and then the circular slide 139 returns to the initial position.

[0045] Then, the transposition motor 109 is started to drive the transposition gear 110 to rotate, that is, the transposition toothed disc 102 is rotated, and the leveling slide 111, the leveling slide 112, the leveling scraper 113, and the leveling pressing plate 114 are rotated synchronously, and finally the leveling scraper 113 is parallel to one side of the embroidery craft, and then the leveling motor 117, the leveling motor 118, and the adjusting electric cylinder 119 are started, firstly the two sides of the embroidery craft of the leveling pressing plate 114 are pressed, and then the leveling scraper 113 is moved on the surface of the embroidery craft to level the surface of the embroidery craft, and finally the leveling scraper 113 is moved to the outside of the leveling pressing plate 114, and the embroidery craft is The area to be trimmed of the product is located in the area formed between the closest flat scraper 113 and the flat pressing plate 114. The flat scraper 113 and the flat pressing plate 114 press and fix the two sides of the embroidery craft in this area, and then start the positioning motor 106, the positioning motor 2 121, the height adjustment motor 128, the auxiliary motor 136, and the distance adjustment motor 137 to make the laser head 132 distribute to trim the embroidery craft in the two areas to be trimmed formed between the two flat scrapers 113 and the two flat pressing plates 114. After completing the trimming of the two sides of the embroidery craft, repeat the above steps to trim the other two sides of the embroidery craft.

[0046] When performing circular trimming on the embroidery craft, the staff still spreads the embroidery craft flat on the supporting circular plate 103, repeats the above steps, so that the leveling scraper 113 completes the leveling treatment of the embroidery craft, and then moves the leveling scraper 113 and the leveling pressing plate 114 to the outside of the supporting circular plate 103, and then starts the positioning motor 106, the positioning motor 2 121, and the pressing motor 129, so that the lower surface of the circular slide plate 139 contacts the center position of the embroidery craft, and the circular slide 138 continues to move downward, so that the long arm rotating plate 140 rotates to a horizontal state and contacts the surface of the embroidery craft. At this time, the lower surface of the long arm rotating plate 140 and the lower surface of the circular slide plate 139 are on the same plane, that is, the surface of the embroidery craft is pressed and fixed.

[0047] Then, the reset motor 147 is started to adjust the position of the fan-shaped long strip 143, so that two adjacent fan-shaped short strips 145 move to the position closest to the fan-shaped long strip 143, and the long arm rotating plate 140 corresponding to the two fan-shaped short strips 145 rotates to a vertical upward state, and then the height adjustment motor 128, the auxiliary motor 136, and the distance adjustment motor 137 are started to move the laser head 132 to the fan-shaped area corresponding to the two fan-shaped short strips 145, and then the laser head 132 is started, and then the auxiliary motor 136 is started to drive the laser head 132 to rotate, and the embroidery craftwork is trimmed from the fan-shaped area. When the laser head 132 is relative to the auxiliary ring frame 1 08 is rotating, the laser head 132 is driven to move away from or towards the axis of the auxiliary ring frame 108, so that the laser head 132 can perform wavy or other shape trimming on the embroidery crafts, and the reset motor 147 is started while the auxiliary motor 136 is started to drive the fan-shaped long strip 143 to rotate, and the annular rotating plate 133 and the circular slide 138 rotate synchronously, so that the long arm rotating plate 140 in the feeding direction of the laser head 132 still gives way to the movement of the laser head 132, and the long arm rotating plate 140 after which the laser head 132 has given way returns to the initial position in turn to press and fix the area of ​​the embroidery crafts where the trimming is completed.
