A connecting groove 203 is provided in the middle of the fixed end shell 201 near the connecting end shell 101. The connecting groove 203 extends in the direction of the fixed end shell 201 away from the connecting end shell 101. The socket 202 is arranged in the middle of the connecting groove 203. The locking rod 1011 is installed on both sides of the socket 202 and is fixedly connected to the connecting groove 203. A wiring hole 204 is provided on the side of the fixed end shell 201 away from the connecting end shell 101 and the side of the connecting end shell 101 away from the fixed end shell 201.

[0065] The working process of the present invention is as follows: when the connecting end housing 101 and the fixed end housing 201 are connected, since the joint plate 103 can be movably connected to the pin guard plate 106, when connected, the locking rod 1011 and the undercut 109 on the joint plate 103 are abutted against each other, and after the abutment, the joint plate 103 will move forward along the inclined surface on the undercut 109, and when it moves to the end of the inclined surface, the joint plate 103 rebounds through the limit spring 1010, and after the rebound, the undercut 109 cooperates with the locking rod 1011 to achieve the installation effect of the connecting end housing 101 and the fixed end housing 201;

[0066] When disassembly is required, it is only necessary to press the extrusion plate 1012, and the extrusion plate 1012 drives the push rod 1013 to contact the control plate 107. The control plate 107 drives the coupling plate 103 to swing in the direction away from the locking rod 1011 through the control rod 108, so as to achieve the effect of disengaging the undercut 109 from the locking plate, thereby realizing the separation of the connecting end shell 101 and the fixed end shell 201. Compared with the conventional connection using screws and nuts, the design of the coupling plate 103, the undercut 109 and the locking rod 1011 can effectively prevent the thread from rusting, which makes it difficult to disassemble, and is convenient for disassembly. When disassembling, it is only necessary to press the extrusion plate 1012 to separate the lock and the locking rod 1011 through mechanical movement.

[0067] like Figure 17-23 As shown, the correcting mechanism comprises a top cover 1, a support frame 2, a support plate 3 and a support rod 4, wherein the first correcting motor 5 and the second correcting motor 6 are respectively installed inside the support frame 2, the first correcting motor 5 is vertically installed at one end of the support frame 2, and the second correcting motor 6 is horizontally installed on the surface of the support frame 2, one end of the support frame 2 is connected with an adjusting frame 7, and a transmission wheel 8 is installed on the surface of the adjusting frame 7, the output end of the first correcting motor 5 abuts against the surface of the transmission wheel 8 through a horizontal transmission belt 9, and the transmission wheel 8 is used to drive the adjusting frame 7 to adjust the angle, and a correcting wheel 10 for adjusting the direction of the cloth is installed at one end of the adjusting frame 7 away from the transmission wheel 8, and the correcting wheel 10 is connected to the adjusting frame 7 through a fixing frame 11, and the output end of the second correcting motor 6 abuts against the surface of the correcting wheel 10 through a vertical transmission belt 12;

[0068] The cloth needs to be placed on the workbench when sewing, but since the cloth is a flexible structure, it may be wrinkled or overlapped under the influence of the force. This structure connects the power supply to the output end of the first deviation correction motor 5 to generate a driving force, thereby driving the horizontal transmission belt 9 and the transmission wheel 8 to fine-tune the angle. When the transmission wheel 8 rotates, it drives the adjustment frame 7 to move together, thereby completing the vertical activity adjustment of the adjustment frame 7. When the power supply is connected to the output end of the second deviation correction motor 6 to generate a driving force to drive the vertical transmission belt 12, the transmission force generated by the deviation correction wheel 10 driven by the vertical transmission belt 12 is used to smooth the wrinkled cloth, thereby completing the deviation correction process.

[0069] The correcting wheel 10 is symmetrically installed at both ends of the fixing frame 11, and the correcting wheel 10 is movably connected to the fixing frame 11 through a fixing shaft 13. The surface of the fixing frame 11 is provided with an adjusting bolt 14 for adjusting the movable tightness of the correcting wheel 10; the correcting wheel 10 is symmetrically installed and movably connected through the fixing shaft 13, which can ensure that the cloth maintains the correct centering position during the transmission process and avoids quality problems caused by cloth deviation, and the adjusting bolt 14 can facilitate the operator to adjust the tightness of the correcting wheel 10, so that the operator can adjust the correcting force in real time according to actual production needs, ensuring that the cloth is always in the best transmission state, so as to flexibly respond to cloth processing needs of different thicknesses, materials and widths, thereby enhancing the versatility and applicability of the equipment.

[0070] The motion trajectory of the second correcting motor 6, the vertical transmission belt 12 and the correcting wheel 10 is a triangular circular activity. The use of a triangular circular motion trajectory can increase the stability of force transmission, effectively reduce the direct friction and wear between the correcting wheel 10 and other mechanical parts, and further enhance the durability of the equipment.

[0074] One end of the mounting frame 1 is provided with a flipping motor 9 for assisting the loading platform 4 to rotate, one end of the flipping motor 9 is in contact with the surface of the loading platform 4, and the left loading part 100 includes a support platform 10, and the surface of the support platform 10 is connected with a rotating device for rotating the cloth; this structure adopts a structure with independent but similar loading parts at both ends, namely the left loading part 100 and the right loading part 200, respectively.

One end of the machine 17 is meshed with the toothed structure on the inner surface of the conveyor frame 2; this structure can realize linear displacement, ensuring that the support plate 5 and the components thereon can move along the Y-axis direction of the conveyor frame 2. When processing longer cloth, the drive motor 17 can be started to rotate one end of the drive motor 17 to mesh with the toothed structure on the inner surface of the conveyor frame 2, thereby driving the position of the support plate 5 to optimize the unfolding and alignment of the cloth; a locking block 18 for limiting the movable stroke is installed inside the support plate 5, and one end of the locking block 18 is a twistable structure; the locking block 18 can be locked at a specified position by twisting, so that the locking block 18 hugs the surface of the conveyor frame 2 to form a braking effect of the brake pad. By setting the locking block 18, it is effectively avoided that the mechanical movement or activity exceeds the predetermined working range, and equipment damage or safety accidents caused by excessive movement are prevented, thereby improving the adaptability and flexibility of the equipment.

[0078] The key points of the present invention are: the left and right ends are provided with independent but similarly structured feeding parts, namely the left feeding part 100 and the right feeding part 200. This structure allows one side to continue working while the other side is undergoing maintenance or preparation, thereby ensuring the continuity of production.
