[0018] The embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings.

[0019] Figures 1 to 4 Shown is a schematic structural diagram of the utility model.

[0020] The accompanying drawings are marked as follows: a deflection correction mounting plate 1, a deflection correction rotating wheel 2, a cloth feeding wheel 3, a spindle motor 4, a deflection correction motor 5, a guide mounting plate 6, a slide rail mounting plate 7, a cylinder 8, a cylinder mounting frame 9, a cylinder joint 10, a cylinder connecting plate 11, a first slide rail 12, a first slider 13, a guide roller 14, a baffle wheel mounting block 15, an auxiliary pressure plate 16, a curved portion 16a, a fixing portion 16b, a baffle fixing plate 17, a rotating shaft 18, an air blowing pipe 19, a spring connection Block 20, spring limit block 21, extension part 21a, spring 22, first wire hook 22a, second wire hook 22b, spring fixing block 23, mounting base plate 24, movable plate 25, front and rear drive motor 26, motor mounting seat 27, screw mounting frame 28, ball screw pair 29, screw moving block 30, movable connecting block 31, second slide rail 32, third slide rail 33, second slider 34, third slider 35, mounting vertical plate 36, mounting flat plate 37.

[0021] The deflection correction guide auxiliary mechanism of the utility model comprises an auxiliary pressing plate 16 mounted on the guide mounting plate 6, a guide roller 14, and a cylinder 8. The auxiliary pressing plate 16 presses the processed fabric on the deflection correction rotating wheel 2, and the guide roller 14 guides the processed fabric to move along the deflection correction rotating wheel 2.

[0022] like Figure 1 As shown, the cloth feed wheel 3 is rotatably mounted on the deflection correction mounting plate 1, and a plurality of deflection correction wheels 2 for correcting the deflection of cloth are mounted on the cloth feed wheel 3. The deflection correction mounting plate 1 is mounted with a spindle motor 4 for driving the cloth feed wheel 3 to rotate, and a deflection correction motor 5 for driving the deflection correction wheel 2 to rotate. A secondary wheel which rotates synchronously with the cloth feed wheel 3 is mounted at the front end of the deflection correction wheel 2. The spindle motor 4 and the deflection correction motor 5 cooperate with each other to correct the position of the cloth edge during the cloth feeding process, thereby improving the accuracy of the sewing position and the sewing effect.

[0023] like Figure 2 As shown, a slide rail mounting plate 7 is fixed on the deviation correction mounting plate 1, the cylinder body of the cylinder 8 is fixedly connected to the slide rail mounting plate 7 through the cylinder mounting frame 9, the piston rod of the cylinder 8 is connected to the cylinder joint 10, and the cylinder joint 10 is fixedly connected to the guide mounting plate 6 through the cylinder connecting plate 11. The slide rail mounting plate 7 is installed with the first slide rail 12, and two first sliders 13 are installed on the guide mounting plate 6 to cooperate with the first slide rail 12. The piston rod of the cylinder 8 extends to drive the guide mounting plate 6 to move horizontally along the first slide rail 12, thereby controlling the distance between the auxiliary pressure plate 16 and the guide roller 14 and the deviation correction rotating wheel 2.

[0024] like Figure 3As shown, the guide roller 14 is rotatably mounted on the stop wheel mounting block 15, the stop wheel mounting block 15 is fixedly connected to the guide mounting plate 6, and the piston rod of the cylinder 8 drives the guide mounting plate 6 to move, and at this time the guide roller 14 moves to the bottom of the cloth feeding wheel 3. When the processed fabric rotates upward along the cloth feeding wheel 3, the processed fabric below the cloth feeding wheel 3 cannot be closely attached to the deflection correcting wheel 2 due to the influence of gravity. The guide roller 14 is installed below the cloth feeding wheel 3, which increases the contact area between the processed fabric and the deflection correcting wheel 2. The guide roller 14 guides the processed fabric to rotate along the cloth feeding wheel 3, and the processed fabric is corrected by the deflection correcting wheel 2.

[0025] The auxiliary pressing plate 16 has a curved portion 16a and a fixed portion 16b. The curvature of the curved portion 16a matches the curvature of the cloth feeding wheel 3. The curved portion 16a of the auxiliary pressing plate 16 can press the processed cloth on the deflection correcting wheel 2. The fixed portion 16b is a vertical flat plate. The fixed portion 16b is installed at one end of the rotating shaft 18 through a baffle fixing plate 17. An air blowing pipe 19 is provided at the front side of the fixed portion 16b. The air blowing pipe 19 blows the curling portion toward the hem edge of the processed cloth to straighten the hem.

[0026] like Figure 4 As shown, one end of the rotating shaft 18 is connected to the auxiliary pressure plate 16, and the other end of the rotating shaft 18 is connected to the spring connecting block 20, and the spring connecting block 20 is fixedly connected to the guide mounting plate 6. The spring limit block 21 is sleeved on the rotating shaft 18, and the spring limit block 21 is fixed to the rotating shaft 18 by screws, and the spring limit block 21 rotates with the rotating shaft 18. The spring limit block 21 is provided with an extension portion 21a extending upward, and a groove is provided on the extension portion 21a. The spring 22 is sleeved on the rotating shaft 18, and the spring 22 is located between the spring connecting block 20 and the spring limit block 21. The spring 22 has two "L"-shaped hooks, namely the first hook 22a and the second hook 22b. The first hook 22a is engaged with the groove on the extension portion 21a, and the second hook 22b is inserted into the small hole of the spring connecting block 20, and the second hook 22b is restricted in the small hole of the spring connecting block 20 via the spring fixing block 23. In this embodiment, the angle formed by the first wire hook 22a and the second wire hook 22b is 180 degrees. According to needs, the angle formed by the first wire hook 22a and the second wire hook 22b can be 90 degrees to 180 degrees.

[0027] The auxiliary pressing plate 16 is close to the processed fabric on the deflection correction wheel 2, and the auxiliary pressing plate 16 drives the rotating shaft 18 to rotate, the spring limit block 21 rotates with the rotating shaft 18, the second hook 22b of the spring 22 is fixed, and the first hook 22a rotates with the spring limit block 21 to compress the spring 22. The spring 22 is forced to open and push the spring limit block 21 on the rotating shaft 18 to rotate, and the rotating shaft 18 drives the auxiliary pressing plate 16 to press the processed fabric. The spring limit block 21 limits the opening angle of the spring 22, and the auxiliary pressing plate 16 presses the processed fabric on the deflection correction wheel 2 to an appropriate amount to prevent the auxiliary pressing plate 16 from exerting too much pressure on the processed fabric and affecting the deflection correction.

[0028] The auxiliary pressing plate 16 will continue to press the processed fabric under the force of the spring 22; when the force on the spring 22 decreases, the auxiliary pressing plate 16 will reduce the pressure on the processed fabric. The spring 22 elastically limits the pressure of the auxiliary pressing plate 16 on the processed fabric, ensuring that the auxiliary pressing plate 16 can press the processed fabric and assist the deflection correction wheel 2 to achieve a better deflection correction effect.

[0029] The deflection correction guide auxiliary mechanism is installed on the slide rail mounting plate 7, and the slide rail mounting plate 7, the deflection correction wheel 2, and the cloth feeding wheel 3 are installed on the front side of the deflection correction mounting plate 1. The front and rear drive motors 26 drive the deflection correction mounting plate 1 to move forward and backward, and are used to set the power on and power off state.

[0030] The screw mounting frame 28 is fixedly mounted on the mounting base 24, and the body of the front and rear drive motor 26 is fixedly connected to the screw mounting frame 28 through the motor mounting seat 27. A ball screw pair 29 is installed in the screw mounting frame 28, and the driving connecting rod of the front and rear drive motor 26 is connected to the screw of the ball screw pair 29. The screw moving block 30 is sleeved on the nut of the ball screw pair 29, and the screw moving block 30 is connected to the moving plate 25 through the moving connecting block 31. The second slide rail 32 and the third slide rail 33 are installed on the mounting base 24, and two second sliders 34 and a third slider 35 are installed on the bottom surface of the moving plate 25 to cooperate with the second slide rail 32 and the third slide rail 33 respectively, and the moving plate 25 moves along the second slide rail 32 and the third slide rail 33.

[0031] The front and rear drive motor 26 drives the screw of the ball screw pair 29 to rotate, the nut of the ball screw pair 29 drives the screw moving block 30 to move forward and backward, and the moving connecting block 31 drives the moving plate 25 to move forward and backward along the second slide rail 32 and the third slide rail 33. The mounting vertical plate 36 is installed on the moving plate 25, the mounting vertical plate 36 is connected to the mounting flat plate 37, and the mounting flat plate 37 is fixedly connected to the rear side of the deviation correction mounting plate 1, and the front and rear drive motor 26 drives the deviation correction mounting plate 1 to move forward and backward.
