DETAILED DESCRIPTION

[0018] like Figure 1 and Figure 2 As shown, a fabric sewing fixing frame includes a connecting frame 1, which is U-shaped. A support rod 2 is provided at the bottom of the connecting frame 1, and the support rod 2 is symmetrically arranged. A support leg 3 is connected to the bottom of the support rod 2. It also includes an elastic support platform 4 for tightening and flattening the fabric when sewing, a guide fixing mechanism 5 and a winding assembly 6 for positioning the conveyed fabric. The elastic support platform 4 is arranged in the middle of the inner wall relative to the connecting frame 1, the winding assembly 6 is arranged on the opening side of the connecting frame 1, and the guide fixing mechanism 5 is arranged on the side of the connecting frame 1 away from the winding assembly 6. The connecting frame 1 arranges and supports the winding assembly 6, the elastic support platform 4 and the guide fixing mechanism 5 in turn, so that the double-layer fabric enters through the guide fixing mechanism 5, and the winding of the double-layer fabric is driven by the winding assembly 6, so as to realize adaptive support for the fabric, and cooperate with the sewing machine to sew the fabric.

[0019] like Figure 1 , Figure 3 and Figure 4 As shown, in order to fix the fabric being rolled and conveyed, the guide and fixing mechanism 5 includes a limit frame 7, a cylinder 8, an extrusion block 9, a roller 10 and a guide assembly 11. The limit frame 7 is arranged between the opposite inner walls of the support frame, the cylinder 8 is arranged in the middle of the side wall of the connecting frame 1 away from the opening, the extrusion block 9 is arranged at the telescopic end of the cylinder 8, and the roller 10 is arranged on the upper and lower sides of the extrusion block 9. The rollers 10 are symmetrically arranged up and down, and the guide assembly 11 is arranged on the side of the connecting frame 1 away from the opening of the connecting frame 1. When the winding assembly 6 is connected to the fabric for winding, the cylinder 8 is controlled by the PLC program to be linked with the rotating motor 19. When the cylinder 8 is extended, the extrusion block 9 contacts the end face of the limit frame 7, so that the fabric is stuck between the limit frame 7 and the extrusion block 9. At the same time, the rotating motor 19 stops rotating, and the roller 10 supports the fabric to prevent the fabric from being worn at the corners of the extrusion block 9.

[0020] like Figure 1-4As shown, in order to support the suspended winding fabric and realize the sewing processing of the sewing machine, the elastic support platform 4 includes a support plate 12, a slide bar 13, a support spring 14 and a processing plate 15. The support plate 12 is arranged in the middle of the inner wall relative to the connecting frame 1, and the slide bar 13 penetrates the support plate 12 and slides in the support plate 12. The slide bar 13 is U-shaped with bent ends. The processing plate 15 is arranged on the two end surfaces of the bent slide bar 13. The support spring 14 is wound around the outer side walls of the two ends of the slide bar 13. The support spring 14 is located between the processing plate 15 and the support plate 12. The support spring 14 pushes the processing plate 15 to rise. At the same time, the slide bar 13 limits the processing plate 15, so that the processing plate 15 pushes the supporting fabric to make the fabric in a taut state. The processing plate 15 provides a sewing processing plane for the sewing machine.

[0021] like Figure 1-3 As shown, in order to guide the double-layer fabric into the limiting frame 7, the guide assembly 11 includes an inclined rod 16 and a guide roller 17. The inclined rod 16 is arranged on the outer wall of the connecting frame 1 away from the opening. The inclined rods 16 are symmetrically arranged in pairs. The guide rollers 17 are rotatably arranged between the inclined rods 16 symmetrical on the same side. The guide rollers 17 are symmetrically arranged up and down. The inclined rods 16 support the guide wheels, so that the double-layer fabric enters the limiting frame 7 after being bent at a certain angle from both sides, so that the double-layer fabric is spliced ​​and attached together.

[0022] In order to ensure that the fabric has conveying power when sewing, the winding assembly 6 includes a protective shell 18, a rotating motor 19, a winding roller 20 and a reduction gearbox 21. The protective shell 18 is arranged on one side of the connecting frame 1 close to the opening, the rotating motor 19 is arranged in the protective shell 18, the reduction gearbox 21 is arranged on the other side of the connecting frame 1 close to the opening, and the winding roller 20 is arranged at the output end of the reduction gearbox 21 and the rotating motor 19. The front end of the double-layer fabric is wound on the winding roller 20, which is connected to the reduction gearbox 21 through the rotating motor 19, and the winding roller 20 is slowly wound up.

[0023] Among them, the extrusion block 9 is set in a trapezoidal shape, and the side corner of the limit frame 7 close to the extrusion block 9 is chamfered to prevent the fabric from stopping to roll up and the corner of the limit frame 7 from squeezing and damaging the surface of the fabric. The height of the extrusion block 9 is greater than the internal height of the limit frame 7, and the front end of the extrusion block 9 is inserted into the limit frame 7 and fixed.

[0024] During specific use, the operator passes the front end of the double-layer fabric through the symmetrical guide wheels, bypasses the rollers 10 on the upper and lower sides of the extrusion block 9, and penetrates into the limit frame 7. The double-layer fabric passes over the processing plate 15 at the same time, and is finally wound on the winding roller 20. During sewing, the cylinder 8 extends to insert the front end of the extrusion block 9 into the limit frame 7 to fix the double-layer fabric. At the same time, the rotating motor 19 stops rotating, and the supporting spring 14 pushes the processing plate 15 upward under the limiting action of the slide bar 13, so that the fabric is in a supported and taut state. The sewing machine sews the double-layer fabric under the support of the processing plate 15. After sewing, the cylinder 8 contracts, and the rotating motor 19 continues to rotate, driving the double-layer fabric to move, waiting for the next fabric sewing and routing.

[0025] Although the embodiments of the utility model have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the utility model, and the scope of the utility model is defined by the attached claims and their equivalents.
