[0023] The present invention also discloses a method for using the automatic auxiliary mechanism for sewing cloth, comprising the following steps:

[0024] S1. Put the fabric on the lower surface of the positioning clamp. At this time, the positioning clamp positions the fabric on the upper surface of the machine table through the fixing frame under the action of the spring rod. The positioning clamp contacts the fabric through the progressive block. During the process of sewing the fabric, the driving motor drives the first rotating disk to rotate through the mounting rod. As the first rotating disk rotates, the driving rod is driven to move through the positioning disk. At this time, under the action of the fixed block, the progressive block is driven to move inside the stroke groove under the limit of the connecting block. Under the action of the limit disk, the progressive block is lifted up when it moves back and forth. As the progressive block moves back and forth, the fabric is driven to move progressively while sewing.

[0025] S2, under the action of the fixed block on the other side, the second rotating disk is driven to rotate, thereby driving the positioning rod to rotate, and the first sprocket is driven to rotate with the rotation of the positioning rod. Under the action of the toothed chain, the second sprocket drives the rotating rod to rotate, and the cam is driven to rotate with the rotation of the rotating rod;

[0026] S3. At this time, under the action of the cam, the pulley drives the pressing plate to move through the support block. Under the action of the telescopic spring, the pressing plate will move up and down, and the pressing plate will squeeze the telescopic airbag. The gas inside the telescopic airbag after being squeezed will be injected into the inside of the air outlet pipe through the connecting pipe. At this time, the gas inside the air outlet pipe is blown toward the cloth through the air outlet hole to clean the fluff on the cloth;

[0027] S4. When the pleating density of the fabric needs to be adjusted, the self-locking threaded rod is driven to rotate by rotating the telescopic rod. As the self-locking threaded rod rotates, the threaded plate drives the adjustment block to move into the movable groove through the fixed rod under the action of the outer surface thread. As the adjustment block moves, the contact area between the progressive block and the fabric decreases.

[0028] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0029] 1. In the present invention, an adjustment component is provided. When the pleating density of the cloth needs to be adjusted, the self-locking threaded rod is driven to rotate by rotating the telescopic rod. As the self-locking threaded rod rotates, the threaded plate drives the adjustment block to move toward the inside of the movable groove through the fixed rod under the action of the outer surface thread. As the adjustment block moves, the contact area between the progressive block and the cloth is reduced, and the bottom area of ​​the progressive block is changed, so as to reduce the contact area between the progressive block and the cloth, thereby realizing the function of the progressive block to change the pleating density, reflecting the versatility of the auxiliary mechanism, and improving the working efficiency of the cloth sewing equipment and the quality of cloth sewing.

[0030] 2. In the present invention, a progressive assembly is provided, and the cloth is placed on the lower surface of the positioning clamp. At this time, the positioning clamp positions the cloth on the upper surface of the machine table through the fixed frame under the action of the spring rod. The positioning clamp contacts the cloth through the progressive block. During the cloth sewing process, the driving motor drives the first rotating disk to rotate through the mounting rod. As the first rotating disk rotates, the driving rod is driven to move through the positioning disk. At this time, under the action of the fixed block, the progressive block is driven to move inside the stroke groove under the limit of the connecting block. Under the action of the limit disk, the progressive block is lifted up when it moves back and forth. As the progressive block moves back and forth, the cloth is driven to move progressively while sewing. Under the action of the positioning clamp, the flatness of the cloth around sewing can be ensured, the sewing effect is improved, and the cloth is automatically conducted under the action of the progressive block, further improving the sewing efficiency.

[0031] 3. In the present invention, an anti-blocking component is provided, and the second rotating disk is driven to rotate under the action of the fixed block on the other side, thereby driving the positioning rod to rotate. As the positioning rod rotates, the first sprocket wheel is driven to rotate. Under the action of the toothed chain, the second sprocket wheel drives the rotating rod to rotate. As the rotating rod rotates, the cam is driven to rotate. At this time, under the action of the cam, the pulley drives the pressure plate to move through the supporting block. Under the action of the telescopic spring, the pressure plate will move up and down, and the pressure plate will squeeze the telescopic airbag. The gas inside the telescopic airbag after being squeezed will be injected into the interior of the air outlet pipe through the connecting pipe. At this time, the gas inside the air outlet pipe is blown toward the cloth through the air outlet hole to clean the fluff on the cloth. The function of automatic cleaning is realized in the process of cloth conduction, reducing the possibility of fluff entering the needle drop bin, avoiding the increase of fluff in large quantities as the sewing time increases, increasing the resistance to needle movement, and reducing the needle breakage as much as possible, thereby improving the quality of the sewing equipment.

2. The method for using the automatic auxiliary mechanism for sewing cloth according to claim 1, characterized in that: The steps include: S1, placing the fabric on the lower surface of the positioning clamp (3), at which time the positioning clamp (3) positions the fabric on the upper surface of the machine table (1) through the fixing frame (4) under the action of the spring rod (5), the positioning clamp (3) contacts the fabric through the progressive block (87), and during the process of sewing the fabric, the driving motor (81) drives the first rotating disk (82) to rotate through the mounting rod, and as the first rotating disk (82) rotates, the driving rod (84) is driven to move through the positioning disk (83), and at this time, under the action of the fixing block (812), the progressive block (87) is driven to move inside the travel groove (810) under the limit of the connecting block (88), and under the action of the limit disk (811), the progressive block (87) is lifted up when it moves back and forth, and as the progressive block (87) moves back and forth, the fabric is driven to move progressively while sewing; S2. Under the action of the fixed block (812) on the other side, the second rotating disk (85) is driven to rotate, thereby driving the positioning rod (86) to rotate. As the positioning rod (86) rotates, the first sprocket wheel (9) is driven to rotate. Under the action of the sprocket wheel, the second sprocket wheel (10) drives the rotating rod (710) to rotate. As the rotating rod (710) rotates, the cam (711) is driven to rotate. S3, under the action of the cam (711), the pulley (79) drives the pressing plate (76) to move through the support block (78), and under the action of the telescopic spring (75), the pressing plate (76) moves up and down, and the pressing plate (76) squeezes the telescopic airbag (77). The gas inside the telescopic airbag (77) after being squeezed is injected into the inside of the air outlet pipe (71) through the connecting pipe (74). At this time, the gas inside the air outlet pipe (71) is blown toward the cloth through the air outlet hole (73), so as to clean the fluff on the cloth; S4. When the pleating density of the fabric needs to be adjusted, the self-locking threaded rod (65) is driven to rotate by rotating the telescopic rod (66). As the self-locking threaded rod (65) rotates, the threaded plate (64) drives the adjusting block (62) to move toward the inside of the movable groove (61) through the fixed rod (63) under the action of the outer surface thread. As the adjusting block (62) moves, the contact area between the progressive block (87) and the fabric decreases.
