[0002] The sewing fabric power wheel device is an auxiliary traction device for sewing machines designed specifically to improve sewing quality. This device uses electric or other drive methods to assist the fabric to run smoothly during the sewing process, ensuring that the seams and press seams are wrinkle-free and layered, while maintaining the uniformity of the sewing stitch length. It is particularly suitable for clothing products that have extremely high craftsmanship requirements and require the use of high-end fabrics for sewing.

[0003] However, the distance between the two power-assisting wheels of the existing sewing fabric power-assisting wheel device is fixed, resulting in the lack of the function of adjusting the distance between the power-assisting wheels by lifting and lowering pressure, which leads to certain limitations in actual use and greatly reduces the practicality of the device. Therefore, a power-assisting wheel device with adjustable lifting and lowering pressure for sewing fabrics is proposed. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Specifically, such as Figure 2 As shown, the drive motor 3 is an AC asynchronous motor, which is mainly composed of a stator, a rotor, bearings, a casing, a cooling system and terminal blocks. Its working principle is based on the electromagnetic induction phenomenon. When AC current passes through the stator winding, a rotating magnetic field is generated between the stator and the rotor, and then a current is induced in the rotor. This induced current interacts with the rotating magnetic field to generate electromagnetic force, driving the rotor to rotate, thereby realizing the conversion of mechanical energy.

[0022] Specifically, such as Figure 2As shown, the cylinder 14 is a key component in the pneumatic system, which is mainly composed of a cylinder barrel, front and rear end covers, a piston, a piston rod and a sealing ring. The cylinder barrel is the main structure and is made of high-strength material to ensure the pressure-bearing capacity. The front and rear end covers seal the two ends of the cylinder barrel to form a sealed chamber. The piston assembly includes a piston body and a piston rod. The piston reciprocates in the cylinder barrel, and the piston rod is connected to the external load to realize force transmission. The sealing ring ensures that the gas will not leak in the cylinder barrel to maintain the normal operation of the system. The working principle of the cylinder 14 is based on the Pascal principle. Compressed air is input into one end of the cylinder 14 to push the piston to the other end, thereby driving the load to move. When the gas pressure is released or reduced, the piston returns to its initial position. This linear reciprocating motion realizes the conversion of gas energy to mechanical energy and is widely used in automation equipment and mechanical manufacturing.

[0023] During implementation, follow these steps:

[0024] 1) Turn on the drive motor 3 and drive the first rotating rod 6 to rotate inside the first shaft seat 5 through the two pulleys 4 and the belt;

[0025] 2) Then, through the transmission of the two gears 11, the second rotating rod 10 is driven to rotate in the second shaft seat 9;

[0026] 3) Finally, the cylinder 14 is opened to move the connecting plate 13 through its telescopic end, thereby cooperating with the spring body 12, the movable rod 8 and the sleeve rod 7 to adjust the distance between the first rotating rod 6 and the second rotating rod 10, thereby adjusting the size of the lifting pressure.

[0027] To sum up, the power-assisted wheel device with adjustable lifting pressure for sewing fabrics, when the driving motor 3 is turned on, the first rotating rod 6 can be rotated in the first shaft seat 5 through the two pulleys 4 in cooperation with the belt, and then the second rotating rod 10 is driven to rotate in the second shaft seat 9 through the rotation of the first rotating rod 6 and the gear 11, thereby assisting the traction of the fabric, and then the cylinder 14 is turned on, and the connecting plate 13 is driven to move through the telescopic end of the cylinder 14, so as to cooperate with the spring body 12, the movable rod 8 and the sleeve rod 7 to adjust the distance between the first rotating rod 6 and the second rotating rod 10, thereby achieving the purpose of adjusting the lifting pressure.
