Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

The cam 24 has two support legs 26 which are used to support the base 1. The cam 24 has two support legs 26 which are used to support the base 1. The cam 24 has two support legs 26 which are used to support the base 1.

[0031] Reference Figure 2- Figure 4 The fixing mechanism includes a slide rod 11. The top of the slide rod 11 is provided with a convex block configured as a hemisphere. The slide rod 11 is slidably installed on the inner wall of the positioning block 9. The slide rod 11 is arranged inside the positioning block 9 located on the front and rear sides of the roller 7. An air pressure cabin 12 is opened inside the positioning block 9. The air pressure cabin 12 has the function of transmitting pressure. The bottom of the slide rod 11 is elastically connected to the inner wall of the air pressure cabin 12 through a spring 13. The top of the spring 13 is fixedly connected to the bottom of the slide rod 11. The bottom of the spring 13 is elastically connected to the inner wall of the air pressure cabin 12. By setting the spring 13, an upward elastic force is applied to the slide rod 11.

[0032] Reference Figure 3 、 Figure 4 The fixing mechanism also includes an arc block 14, which is slidably mounted on the inner wall of the air pressure cabin 12. The bottom of the arc block 14 is fixedly connected with a bite tooth 15 for clamping the cloth. The bite tooth 15 can increase the friction with the cloth and reduce the possibility of slipping after the cloth is fixed. The number of bite teeth 15 is set to multiple, and the multiple bite teeth 15 are arranged in a straight line at the bottom of the arc block 14 at equal intervals. A pressing groove 16 is provided on the top of the roller 8. When the arc block 14 is displaced, the cloth is pressed against the pressing groove 16, further improving the stability of the cloth fixation. The vertical projection area of ​​the arc block 14 is smaller than the vertical projection area of ​​the pressing groove 16.

[0033] Reference Figure 1 、 Figure 2 The clamping mechanism includes a stepper motor 3, which can accurately control the rotation angle of its output shaft, conveniently adjust the rotation speed and rotation angle of its rotation shaft, and can be adjusted accordingly according to different work requirements to improve the control accuracy. The stepper motor 3 is fixedly mounted on the top of the base 1, and the front end of the output shaft of the stepper motor 3 is fixedly connected to a turntable 4. The clamping mechanism also includes an electric cylinder 5, which is fixedly mounted on the top of the base 1.

[0034] Reference Figure 1 、 Figure 2 The rear side of the output shaft of the electric cylinder 5 is rotatably connected to the turntable 2 6. When the electric cylinder 5 is working, it drives the turntable 2 6 to move forward and backward. The central axis of the turntable 2 6 coincides with the central axis of the turntable 1 4. The front side of the turntable 1 4 and the rear side of the turntable 2 6 are both provided with positioning grooves 10. The positioning block 9 is set to a cross shape. The shape of the positioning block 9 matches the shape of the positioning groove 10. Through the cooperation of the positioning block 9 and the positioning groove 10, when the positioning block 9 is installed inside the positioning groove 10, the roller 1 7 and the roller 2 8 can be stably combined into a whole, which is convenient for fixing and winding the cloth.

[0035] Working principle: When in use, one end of the cloth is placed flat between roller 1 7 and roller 2 8, and then roller 1 7 and roller 2 8 are merged so that one end of the cloth is pressed against the inside of the clamping groove 16 by the engaging teeth 15 at the bottom of the arc block 14, and the positioning block 9 is made into a complete cross shape, and then the positioning block 9 at the rear side is placed inside the positioning groove 10 on the front side of turntable 1 4, and then the power supply of the electric cylinder 5 is started to make the turntable 2 6 move backward until the positioning block 9 at the front side enters the inside of the positioning groove 10 on the rear side of turntable 2 6, thereby clamping the cylinder formed by roller 1 7 and roller 2 8, and then the power supply of the stepper motor 3 is started so that the turntable 1 4 drives the turntable 2 6 and the cylinder formed by roller 1 7 and roller 2 8 to rotate synchronously, thereby winding the cloth around the surface of roller 1 7 and roller 2 8 for winding operation.

[0036] During the above operation, when the positioning block 9 enters the interior of the positioning groove 10, the edge of the positioning groove 10 will squeeze the slide bar 11 on the top of the positioning block 9, causing the slide bar 11 to overcome the elastic force of the spring 13 and move downward. The displacement of the slide bar 11 reduces the volume of the space inside the air pressure chamber 12, thereby increasing the pressure inside the air pressure chamber 12, thereby pushing the arc block 14 to drive the bite teeth 15 to move downward, thereby pressing the cloth against the inner wall of the pressing groove 16, and the increased pressure inside the air pressure chamber 12 will be continuously transmitted to the cloth surface through the bite teeth 15, thereby increasing the pressure between the bite teeth 15 and the cloth surface, and further increasing the friction between the bite teeth 15 and the cloth surface, reducing the possibility of the cloth slipping during the winding process.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
