DETAILED DESCRIPTION

[0018] The following description is merely a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0019] An automatic sewing and folding device for cotton yarn sewing production, such as Figure 1 and Figure 2As shown, it includes a mounting frame 1, which has two mounting frames 1. A conveying assembly 2 is installed on the front mounting frame 1. The conveying assembly 2 includes a first servo motor, a conveying roller and a conveyor belt. A first servo motor is installed on the right side of the rear of the front mounting frame 1. The conveying roller is connected to the output shaft of the first servo motor. The front of the front mounting frame 1 is also rotatably connected to the conveying roller. Several conveyor belts are connected between the conveyor rollers. A flip assembly 3 is also installed on the front mounting frame 1. The flip assembly 3 includes a driving motor and a flip frame. A driving motor is installed on the right side of the middle of the front mounting frame 1. The flip frame is connected to the output shaft of the driving motor. The flip frame and the conveyor belt are staggered. The interaction between the several conveyor belts and the flip frame allows the cotton yarn to be transported. The folding and flipping frame is rotatably connected to the mounting frame 1 on the front side, and a conveyor belt assembly 4 is installed on the mounting frame 1 on the rear side. The conveyor belt assembly 4 includes a second servo motor, a conveyor roller and a conveyor belt. A second servo motor is installed on the right side of the rear part of the mounting frame 1 on the rear side, and a conveyor roller is also connected to the output shaft of the second servo motor. The front part of the mounting frame 1 on the rear side is also rotatably connected to the conveyor roller, and a conveyor belt is connected between the two conveyor rollers on the rear side. The left and right parts of the mounting frame 1 on the rear side are connected to workbenches 5, and spherical power-assisting parts are connected to the workbenches 5. Sewing components 6 are installed on the upper sides of the workbenches 5. A fixing frame 7 is placed between the outer sides of the workbenches 5, and a triangular rib for reinforcement is connected to the fixing frame 7. Two mechanical arm assemblies 8 are slidably connected to the fixing frame 7.

[0020] like Figure 1 and Figure 3 As shown, it also includes a mounting seat 9, the mounting seat 9 is connected to the right side of the rear of the front mounting frame 1, a driving motor 12 is installed on the mounting seat 9, and a rotating plate 10 is connected to the output shaft of the driving motor 12. The right side of the rear of the front mounting frame 1 is also rotatably connected to the rotating plate 10, and a support roller 11 is connected between the two rotating plates 10. Fixed plates 13 are connected to the left and right sides of the front of the rear mounting frame 1, and support rollers 11 are also connected between the fixed plates 13.

[0021] like Figure 1 and Figure 4 As shown, a negative pressure installation component 14 is also included. The lower part of the robot arm component 8 is connected to the negative pressure installation component 14, and the left and right parts of the negative pressure installation component 14 are connected to adsorption plates 15.

[0022] It should be noted that cotton yarn is a linear material spun from cotton fibers, which has excellent moisture absorption, air permeability and comfort. Cotton yarn sewing is a basic skill in the textile industry. Correct sewing techniques and methods can ensure the final quality and durability of the product. Folding and sewing cotton yarn is a common textile process used to wrap the edges of the fabric to increase the durability and aesthetics of the product, prevent the edges of the fabric from being worn and unthreaded, and at the same time improve the overall texture of the product. First, the segmented cotton yarn is placed on the conveyor belt, and the output shaft of the first servo motor drives the conveyor roller to rotate, so that the conveyor belt moves, thereby continuously conveying the cotton yarn. When the cotton yarn moves to the turning frame, the drive motor is started, and the output shaft of the drive motor rotates to drive the turning frame to turn, thereby folding the cotton yarn. The turning frame is staggered with the conveyor belt. Several conveyor belts and the turning frame interact with each other so that the cotton yarn can be folded during transportation. The conveying component 2 continuously conveys the cotton yarn to the conveyor belt. In order to avoid the gap between the conveyor belts causing the cotton yarn to be stuck and unable to move backward, you can Start the drive motor 12, and the rotation of the output shaft of the drive motor 12 will drive the rotating plate 10 to rotate, thereby lifting the front support roller 11 upward, so that the cotton yarn can be better transported to the conveyor belt. When the cotton yarn is transported to the appropriate position on the conveyor belt, the grabbing disc on the robot arm assembly 8 will grab the cotton yarn and put it on the workbench 5 on the left and right sides. The sewing assembly 6 will automatically adjust according to the position where the cotton yarn needs to be sewn. After sewing is completed, the robot arm assembly 8 grabs the cotton yarn again and places it on the conveyor belt for subsequent operations. During the yarn-gripping process, the area of ​​cotton yarn grabbed by the grabbing disc is limited, and due to years of use and mechanical wear, the grabbing force may be unstable, resulting in the cotton yarn falling during the grabbing process, affecting the production efficiency of the cotton yarn. A negative pressure mounting assembly 14 can be installed on the grabbing disc. When the robot arm assembly 8 grabs the cotton yarn downward, the negative pressure mounting assembly 14 discharges the air from the lower part of the cotton yarn and the inside of the adsorption disc 15, so that the adsorption disc 15 adsorbs the cotton yarn, thereby making the robot arm assembly 8 more stable when grabbing the cotton yarn, which is beneficial to improving the production efficiency of the cotton yarn.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
