[0020] In this embodiment, the straightening mechanism 6 includes a mounting plate 61, a driving motor 62, a double-shaft screw rod 63, a movable plate 64, a circular ring 65 and a pneumatic finger 66. Two mounting plates 61 are fixedly installed on the front of the workbench 2. A driving motor 62 is fixedly installed on the right side of the right mounting plate 61. A double-shaft screw rod 63 is rotatably installed between the two mounting plates 61. The output end of the driving motor 62 penetrates through the right mounting plate 61 and is fixedly connected to the double-shaft screw rod 63. The outer peripheral wall of the double-shaft screw rod 63 is threadedly connected with two movable plates 64. One end of the movable plate 64 extends above the workbench 2. A circular ring 65 is fixedly installed on the top of the movable plate 64. A pneumatic finger 66 is fixedly installed on each of the opposite sides of the two movable plates 64;

[0021] The double - shaft screw 63 is composed of two threaded rods with opposite thread directions. A limiting groove is formed in the front of the workbench 2, and a limiting block with one end fixedly connected to the movable plate 64 is slidably installed inside the limiting groove.

[0022] Specifically, pass the cotton yarn strip through the rings 65 on both sides for collection operation. After the collection is completed, operate the pneumatic fingers 66 on both sides to clamp the cotton yarn strip, start the driving motor 62 to drive the double - shaft screw 63 to rotate. The double - shaft screw 63 drives the movable plates 64 on both sides to move away from each other, and the movable plates 64 drive the pneumatic fingers 66 on both sides to move away from each other to straighten the cotton yarn strip.

[0023] In this embodiment, the cutting mechanism 4 includes a hydraulic push rod 41, a lifting plate 42, a cutting knife 43, an electric heating strip 44, a positioning plate 45, and a limiting rod 46. The hydraulic push rod 41 is embedded in the center of the top of the L - shaped plate 3. The output end of the hydraulic push rod 41 is fixedly installed with a lifting plate 42. The cutting knife 43 is fixedly installed at the center of the bottom of the lifting plate 42.

[0024] Specifically, after the cotton yarn strip is straightened, operate the hydraulic push rod 41 to drive the cutting knife 43 to move downward. The positioning plate 45 presses on both sides of the cotton yarn strip, and the cutting knife 43 cuts the cotton yarn strip. Turn on the electric heating strip 44. After the cutting knife 43 cuts the cotton yarn strip, the electric heating strips 44 on both sides contact the cut ends of the cotton yarn strip and melt them to prevent the thread ends from spreading after the cotton yarn strip is cut.

[0025] In this embodiment, the cleaning mechanism 7 includes a linear module 71, a cleaning scraper 72, and a dropping hole 73. Two linear modules 71 are fixedly installed at the center of the back of the workbench 2. The output end of the linear module 71 is fixedly installed with a cleaning scraper 72. A dropping hole 73 opened on the workbench 2 is fixedly installed on the front side of the inner wall of the cutting groove 9. A collection bin 14 is fixedly installed on the front side of the inner wall of the bin body 1 and below the dropping hole 73. The bin door 8 is located at the collection bin 14. An extension groove opened on the workbench 2 is fixedly installed on the rear side of the inner wall of the cutting groove 9. The cleaning scraper 72 matches the cutting groove 9.

[0026] Specifically, after the cotton yarn strip is cut, the debris falls into the cutting groove 9. When the lifting platform 5 descends to be parallel to the workbench 2, operate the linear module 71 to drive the cleaning scraper 72 to push the debris accumulated in the cutting groove 9 to the dropping hole 73 and fall into the collection bin 14. In this way, the purpose of automatically cleaning the debris is achieved.

[0027] In this embodiment, a cylinder 11 is fixedly installed at the center of the top of the bin body 1. A connecting plate 12 is fixedly installed at the output end of the cylinder 11. A lifting table 5 is fixedly installed on the top of the connecting plate 12. Positioning rods 13 are fixedly installed at the four corners of the bottom of the connecting plate 12, with one end of each positioning rod passing through the connecting plate 12 and being fixedly connected to the inner top wall of the bin body 1.

[0028] Specifically, operating the cylinder 11 can drive the connecting plate 12 to lift and lower, and the connecting plate 12 drives the lifting table 5 to move vertically.

[0029] The working principle of the above embodiment is as follows:

[0030] (1) Pass the cotton yarn through the rings 65 on both sides for collection. After the collection is completed, operate the pneumatic fingers 66 on both sides to clamp the cotton yarn, and start the driving motor 62 to drive the double-shaft screw 63 to rotate. The double-shaft screw 63 drives the movable plates 64 on both sides to move away from each other, and the movable plates 64 drive the pneumatic fingers 66 on both sides to move away from each other to straighten the cotton yarn.

[0031] (2) Operate the cylinder 11 to drive the connecting plate 12 to rise. The connecting plate 12 drives the lifting table 5 to move upward to contact the cotton yarn. Operate the hydraulic push rod 41 to drive the cutting knife 43 to move downward. The positioning plate 45 presses on both sides of the cotton yarn strip, and the cutting knife 43 cuts the cotton yarn strip.

[0032] (3) Turn on the electric heating strip 44. After the cutting knife 43 cuts the cotton yarn strip, the electric heating strips 44 on both sides contact the cut ends of the cotton yarn strip and melt them to prevent the cut ends of the cotton yarn from fraying.

[0033] (4) After the cotton yarn strip is cut, the debris falls into the cutting groove 9. Operate the lifting table 5 to descend and reset. Operate the linear module 71 to drive the cleaning scraper 72 to push the debris accumulated in the cutting groove 9 to the dropping hole 73, and the debris falls into the collection bin 14. In this way, the purpose of automatically cleaning the debris is achieved.
