This function can ensure that the cloth always maintains the correct position during the conveying process, thereby ensuring that the lace machine can accurately process the cloth.

[0021] 4. If the fabric is offset, it can be reset by controlling the pressure wheel to move forward and backward. This design eliminates the need to stop the machine and readjust the fabric position when encountering minor problems such as fabric offset, thus reducing the interruption time in the production process and improving production continuity.

[0022] 5. The present invention drives the limiting structure to rotate 90 degrees and controls the movement of the limiting structure, so that the limiting structure is moved to bypass the embossing head and is located above the passed cloth and then descends again for pressing, and then the cloth is driven to be continuously and stably conveyed by the rotation of the conveying wheel, which can effectively pull the cloth and ensure that the cloth can still be stably conveyed after passing through the embossing head, thereby avoiding the cloth from being stuck or insufficiently supplied at key processing locations.

[0050] That is, the second electric push rod 36 in the traction structure 3 drives the limiting structure 4 to descend, and then the conveying wheel 483 in the conveying assembly 48 will first contact the processing table and be forced to compress the spring 47 in the second pressing rod 46, and as it continues to descend, the pressing claw 45 is pressed down and fixed in contact with the cloth;

[0051] Then the dual-axis motor 12 is controlled to drive the conveyor belt 14 on the conveying roller 13 to rotate, and the moving seat 17 is driven to drive the limiting structure 4 to move toward the embossing machine, so as to drive the cloth to be pulled and moved, and one end of the cloth is conveyed to the embossing head of the embossing machine. After the cloth passes through the embossing head, the second electric push rod 36 is retracted to separate the pressing claw 45 from the cloth; then the adjusting arm 42 is located on the left side of the embossing head, and the other end of the limiting arm 41 is located on the right side of the embossing head, and then the second electric slide rail 31 in the traction structure 3 is controlled to drive the third electric slide rail 32 to move left and right, and the third electric slide rail 32 is controlled to control the limiting structure 4 to move forward and backward by a certain distance for cooperation, and the adjusting arm 42 can be driven by the second motor 37 to rotate 90 degrees, so that the adjusting arm 42 bypasses the embossing head and is located above the passing cloth, and then the limiting structure 4 is controlled to descend again, and at this time, the adjusting arm 42 descends after rotation, and the conveying wheel 483 in the conveying assembly 48 presses down the cloth for limited traction;

[0052] The conveying wheel 483 in the conveying assembly 48 will exert a reverse force after contacting the cloth as the second electric push rod 36 extends and descends, that is, the lifting rod 481 squeezes the spring 47 for buffering; finally, the third motor 484 is controlled to drive the conveying wheel 483 to rotate on the wheel frame 482 through the cooperation of the pulley 485 and the transmission belt 486, and the cloth is pulled and moved by the contact between the conveying wheel 483 and the cloth, so as to realize the continuous conveying of the cloth;

[0053] According to the actual cloth processing position, the installation spacing of the two sets of conveying components 48 on the adjusting arm 42 is adjusted; at the same time, according to the width of the cloth, in order to ensure that the conveying wheel 483 can be located on both sides of the processing position, it is necessary to adjust the telescopic arm 35 to adjust the length in the telescopic opening 7 of the support arm 33 and tighten it with the third mounting bolt 34;

[0054] During the process of conveying the cloth, this device can cooperate with the cloth unwinding device to feed the cloth. If the cloth is short, the part of the cloth that has not passed through the pressing component 18 at the right end of the conveying frame 11 may be offset due to gravity, etc. At this time, the first electric slide rail 183 can be controlled to drive the multiple pressing wheels 185 on the wheel plate 184 to move back and forth, and the cloth can be adjusted and corrected by moving in the opposite direction of the cloth offset; after the cloth passes through the pressing component 18, the conveying component 48 can be used to press the cloth down directly and cooperate with the conveyor belt 14 to pull it to the processing table, and then the conveying wheel 483 can be used by the second electric slide rail 31 to drive the cloth to separate from the conveying frame 11 and move it to the processing table, and drive the conveying wheel 483 and the conveyor belt 14 to rotate to cooperate with flat feeding.

[0055] The actual operation of the equipment and the state of the fabric can be controlled by the existing controller, vision-based detection, etc., or it can be semi-automated by manually straightening the fabric.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
