The disc is connected to the threaded rod through a No. 3 belt. The No. 5 belt is driven by rotating the disc counterclockwise to rotate the threaded rod, causing the slider to move forward. The movement of the slider drives the second licker-in roller to move, and the distance between the two licker-in rollers is expanded.

[0010] Optionally, the cotton feeding mechanism further includes a licker-in roller 1, a licker-in roller 2 and a sealing plate, the licker-in roller 1 is rotatably mounted on the inner wall of the funnel, the licker-in roller 2 is rotatably mounted on the inner wall of the funnel, the sealing plate is slidably mounted on the inner wall of the funnel, a No. 3 spring is provided between the sealing plate and the funnel, the No. 3 spring is provided to drive the sealing plate to reset, the licker-in roller 2 contacts the sealing plate, and the relative rotation of the licker-in roller 1 and the licker-in roller 2 forms a cotton filament state that gradually becomes thinner from top to bottom.

[0011] Optionally, the blowing mechanism includes an air pipe, a nozzle and an air jet hole, the air pipe is arranged inside the licker-in roller 2, the nozzle is arranged at the output port of the air pipe, and the air jet hole is opened on the circumferential surface of the licker-in roller 2, and the gas is transported to the nozzle through the air pipe and output to the air jet hole.

[0012] Optionally, the blowing mechanism also includes a brush plate and a pull rope. The brush plate is slidably mounted on the inner wall of the licker-in roller 2, and one side of the pull rope is fixedly mounted on the inner wall of the brush plate. A No. 4 spring is provided between the brush plate and the licker-in roller 2, and the brush plate is driven to reset by the provided No. 4 spring. The brush plate is in contact with the air pipe. Due to the presence of the air jet hole, some cotton may enter the interior of the licker-in roller 2. If too much cotton accumulates, the nozzle may be blocked. After the licker-in roller 2 stops working, the sealing plate is opened and the pull rope is pulled downward.

[0013] Optionally, the blowing mechanism also includes a sealing disk and a fixed pulley. The sealing disk is slidably installed on the inner wall of the licker-in roller 2, and the fixed pulley is rotatably installed on the left side of the funnel. The other side of the pull rope contacts the fixed pulley, and the brush disk gradually moves outward while compressing the No. 4 spring. Static electricity is generated by the contact between the brush of the brush disk and the trachea, and the cotton is adsorbed by static electricity, and then the sliding brush disk is used to take out the cotton.

[0014] The working principle and beneficial effects of the present invention are: 1. In the present invention, the cotton is conveyed through the funnel by the setting of the anti-blocking mechanism, and the feeding plate is driven to rotate by the servo motor and the rotating rod, which can prevent the cotton from accumulating and clogging at the funnel outlet, and maintain the smooth flow of cotton. The traction plate is made to reciprocate left and right by the rotating rod and the reciprocating screw. The movement of the traction plate can make the cotton more uniform during output, and avoid the accumulation of cotton or unstable output. The screen plate is shaken by the vibration motor, and the cotton falls to the top of the screen plate through the funnel. The vibrating screen plate can make the cotton more evenly distributed when passing through, and avoid local accumulation or blockage, thereby ensuring the uniformity of cotton feeding.

[0015] 2. In the present invention, by setting the cotton feeding mechanism, the output port of cotton in the hopper may be blocked due to too much feeding. By moving the dredging plate, the output efficiency of cotton can be improved, and production interruption caused by blockage or uneven output can be reduced. The relative rotation of the licker-in roller 1 and the licker-in roller 2 makes the cotton form a state of gradually thinning cotton whiskers from top to bottom, making the cotton layer loose. When the input amount of cotton is large, the licker-in roller 2 is driven to move by the disc, the threaded rod and the slider. At this time, the distance between the two licker-in rollers is enlarged, so that more cotton can be processed. When the disc is accidentally reversed by external force, it is restricted by the arc wheel and the limit rod, that is, the threaded rod cannot be reversed, preventing the adjustment of the licker-in roller 2 from losing its effect due to accidental contact with external force. When the licker-in roller 2 moves, it will also drive the sealing plate to move, and the sealing plate prevents the cotton from leaking out due to a gap generated when the licker-in roller 2 moves.

[0016] 3. In the present invention, by setting the air blowing device, when the licker-in roller 2 rotates, cotton may adhere to the surface of its licker-in rod and be difficult to clean. If too much accumulation occurs, the combing of the licker-in roller 2 will be insufficient, affecting the subsequent process. The cotton attached to the surface of the licker-in rod is blown off through the air pipe, the nozzle and the air jet hole, which can realize automatic impurity removal, reduce the workload of manual cleaning and improve production efficiency. Because of the existence of the air jet hole, some cotton may enter the interior of the licker-in roller 2. If too much accumulation occurs, the nozzle may be blocked. After opening the sealing disk, the pull rope is pulled downward to drive the brush disk to move gradually outward. The brush of the brush disk contacts the air pipe to generate static electricity, which adsorbs the cotton through static electricity, and then the sliding brush disk is used to remove the cotton.

The traction plate 7 is threadedly installed on the circumferential surface of the reciprocating screw 6. The movement of the traction plate 7 can make the cotton more evenly distributed during output, avoiding cotton accumulation or unstable output. The connecting plate 8 is slidably installed on the circumferential surface of the support frame 1, and the No. 1 spring 9 is arranged between the connecting plate 8 and the support frame 1. The connecting plate 8 is driven to reset by the set No. 1 spring 9. The screen plate 10 is fixedly installed on the left side of the connecting plate 8, and the fixed end of the vibration motor 11 is fixedly installed on the right side of the screen plate 10. The vibrating screen plate 10 can make the cotton more evenly distributed when passing through, avoiding local accumulation or blockage, and ensuring the uniformity of cotton feeding.

[0025] The cotton is transported through the funnel 2, and the output end of the servo motor 3 rotates to drive the No. 1 belt to rotate the rotating rod 4, and the rotation of the rotating rod 4 drives the feeding plate 5 to rotate. The feeding plate 5 can prevent the cotton from accumulating and clogging at the outlet of the funnel 2, and maintain the smooth flow of the cotton. The rotating rod 4 rotates while driving the No. 2 belt to rotate the reciprocating screw rod 6. The rotation of the reciprocating screw rod 6 causes the traction plate 7 to reciprocate left and right. The movement of the traction plate 7 can make the cotton more uniform during output, avoiding the accumulation of cotton or unstable output. The vibration motor 11 is used to make the screen plate 10 shake, and the movement of the screen plate 10 drives the connecting plate 8 to move. Because the connecting plate 8 is slidably mounted on the inner wall of the support frame 1, the vibration motor 11 drives the screen plate 10 to vibrate up and down, and at the same time, the connecting plate 8 is reset by the No. 1 spring 9. The cotton falls to the top of the screen plate 10 through the funnel 2. The vibrating screen plate 10 can make the cotton more evenly distributed when passing through, avoiding local accumulation or blockage, and ensuring the uniformity of cotton feeding.

[0026] Example 2 Reference Figures 1 to 8 , which is the second embodiment of the present invention, is different from the first embodiment in that: Compared with Example 2, the interior of the funnel 2 is further provided with a cotton feeding mechanism for assisting operations when inputting cotton and a blowing mechanism for processing the adhesion of cotton. The cotton feeding mechanism includes a dredging plate 201 and a threaded rod 20. The dredging plate 201 is fixedly mounted on the top of the screen plate 10, and the threaded rod 20 is rotatably mounted on the inner wall of the funnel 2. The dredging plate 201 can improve the output efficiency of cotton and reduce production interruptions caused by blockage or uneven output.

[0027] The cotton feeding mechanism also includes a slider 21, a servo motor 22 and a disc 23. The slider 21 is threadedly mounted on the circumferential surface of the threaded rod 20. The fixed end of the servo motor 22 is fixedly mounted on the right side of the slider 21. The disc 23 is rotatably mounted on the front side of the funnel 2. The disc 23 is connected to the threaded rod 20 through a No. 3 belt, so that the distance between the two licker-in rollers is expanded, so that more cotton can be processed.

[0028] The cotton feeding mechanism also includes an arc wheel 24 and a limit rod 25. The arc wheel 24 is fixedly mounted on the circumferential surface of the disc 23, and the limit rod 25 is slidably mounted on the surface of the funnel 2. A No. 2 spring is provided between the limit rod 25 and the funnel 2. The limit rod 25 is reset by the No. 2 spring. The side of the limit rod 25 close to the arc wheel 14 is set to an arc surface to prevent the adjustment of the licker-in roller 27 from losing its effect due to accidental contact by external force.

[0029] The cotton feeding mechanism also includes a licker-in roller 26, a licker-in roller 27 and a sealing plate 28. The licker-in roller 26 is rotatably installed on the inner wall of the funnel 2, the licker-in roller 27 is rotatably installed on the inner wall of the funnel 2, and the sealing plate 28 is slidably installed on the inner wall of the funnel 2. A No. 3 spring is provided between the sealing plate 28 and the funnel 2. The No. 3 spring drives the sealing plate 28 to reset, and the licker-in roller 2 27 contacts the sealing plate 28. The relative rotation of the licker-in roller 26 and the licker-in roller 27 makes the cotton form a cotton beard state that gradually becomes thinner from top to bottom, making the cotton layer loose.

[0030] The blowing mechanism includes an air pipe 30, a nozzle 31 and an air jet hole 32. The air pipe 30 is arranged inside the licker-in roller 27, the nozzle 31 is arranged at the output port of the air pipe 30, and the air jet hole 32 is opened on the circumferential surface of the licker-in roller 27. The gas will blow off the cotton attached to the surface of the licker-in rod, which can realize automatic impurity removal, reduce the workload of manual cleaning, and improve production efficiency.

[0031] The blowing mechanism also includes a brush plate 33 and a pull rope 34. The brush plate 33 is slidably mounted on the inner wall of the licker-in roller 27. One side of the pull rope 34 is fixedly mounted on the inner wall of the brush plate 33. A No. 4 spring is provided between the brush plate 33 and the licker-in roller 27. The No. 4 spring drives the brush plate 33 to reset. The brush plate 33 contacts the trachea 30. Static electricity is generated by the contact between the brush of the brush plate 33 and the trachea 30. The cotton is adsorbed by static electricity, and then the sliding brush plate 33 is used to take out the cotton.

[0032] The blowing mechanism also includes a sealing disk 35 and a fixed pulley 36. The sealing disk 35 is slidably mounted on the inner wall of the licker-in roller 27, and the fixed pulley 36 is rotatably mounted on the left side of the funnel 2. The other side of the pull rope 34 contacts the fixed pulley 36. The sealing disk 35 is used to seal the opening of the licker-in roller 27.

[0033] When the present embodiment is working, the cotton in the hopper 2 may be blocked at the output port due to too much feeding. At this time, the sieve plate 10 is moved up and down to drive the dredging plate 201 to move. The dredging plate 201 can improve the output efficiency of the cotton and reduce the production interruption caused by blockage or uneven output. The output end of the servo motor 22 is rotated to drive the licker-in roller 27 to rotate. The licker-in roller 1 26 and the licker-in roller 2 27 rotate relative to each other so that the cotton forms a state of gradually thinning cotton whiskers from top to bottom, making the cotton layer loose. When the input amount of cotton is large, the disc 23 is rotated counterclockwise to drive the No. 5 belt to rotate the threaded rod 20, so that the slider 21 moves forward. The movement of the slider 21 drives the licker-in roller 2 27 to move. At this time, the distance between the two lickers is The arc wheel 24 is expanded so that more cotton can be processed. When the disc 23 rotates counterclockwise, it drives the arc wheel 24 to rotate. At this time, the arc wheel 24 contacts the arc surface of the limiting rod 25, causing the limiting rod 25 to slide downward and compress the second spring. That is, when the arc wheel 24 rotates counterclockwise, it is not restricted by the limiting rod 25. When it rotates clockwise, the arc wheel 24 contacts the non-arc surface of the limiting rod 25. At this time, the limiting rod 25 cannot move, that is, the rotation of the arc wheel 24 is restricted, that is, the threaded rod 20 cannot be reversed, preventing the adjustment of the licker-in roller 27 from being lost due to accidental contact by external force. When the licker-in roller 27 moves, it drives the sealing plate 28 to move, and the sealing plate 28 prevents the cotton from leaking out due to a gap generated when the licker-in roller 27 moves. When the licker-in roller 27 rotates, cotton may adhere to the surface of its licker-in rod and is difficult to clean. If too much cotton is accumulated, the licker-in roller 27 will not be combed sufficiently, which will affect the subsequent process. At this time, the rotation of the licker-in roller 27 drives the air pipe 30 to rotate, and the gas is transported to the nozzle 31 through the air pipe 30 and output to the air jet hole 32. At this time, the gas will blow off the cotton attached to the surface of the licker-in rod, so as to realize automatic impurity removal, reduce the workload of manual cleaning, and improve production efficiency. Because of the existence of the air jet hole 32, some cotton may enter the interior of the licker-in roller 27. If too much cotton is accumulated, the nozzle 31 may be blocked. After the licker-in roller 27 stops working, the sealing disk 35 is opened and the pull rope 34 is pulled downward. At this time, the brush plate 33 gradually moves outward and compresses the No. 4 spring at the same time. The brush of the brush plate 33 contacts the air pipe 30 to generate static electricity, which adsorbs the cotton by static electricity, and then cooperates with the sliding brush plate 33 to take out the cotton.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
