Description

Technical Field

[0001] This utility model relates to the field of roller ginning technology, specifically an adjustable roller ginning machine. Background Technology

[0002] A cotton gin is a type of cotton processing machinery that separates lint from seed cotton. The ginning process must not damage the quality of the cotton fibers or the seed cotton. Common types include saw gins and roller gins.

[0003] Chinese utility model patent CN220352298U discloses an adjustable roller ginning machine. Although this adjustable roller ginning machine uses a pressure sensor, a motor, and a guide wheel to keep the belt taut, thereby improving ginning efficiency, the sensitivity of the sensor is affected when exposed to high temperatures, which in turn affects the belt tautness. Furthermore, feeding material into the ginning machine via a feed box is problematic; manual feeding can lead to clogging if too much material is added, or insufficient material can affect ginning efficiency.

[0014] This utility model provides an adjustable roller ginning machine, which has the following beneficial effects:

[0015] 1. This adjustable roller ginning machine, through the cooperation of the belt, drive shaft, and driven shaft, can drive the roller assembly and cutter assembly to rotate, enabling it to process cotton. When the belt becomes loose due to wear, the surface tension of the belt will decrease. Due to the elastic effect of the elastic telescopic rod, through the cooperation of the U-shaped plate and the transmission roller, it pulls the belt upward, so that the tension on the belt surface is balanced with the elastic force of the elastic telescopic rod again, making the belt taut on the surface of the drive shaft and driven shaft. The mechanical tensioning mechanism of the elastic telescopic rod and the transmission roller replaces the traditional sensor, solving the problem of unstable belt tension in high-temperature environments.

[0016] 2. This adjustable roller ginning machine pours cotton into an L-shaped feed box. Through the cooperation of the rotating shaft and turntable, and the cooperation of the sliding plate, sliding groove and connecting plate, the cotton in the L-shaped feed tube is pushed into the ginning machine by the push plate. If it is necessary to change the amount of cotton pushed into the ginning machine, the door of the protective box is opened. Through the cooperation of the external thread and screw hole on the surface of the sliding column, the rotation radius of the sliding column can be changed, which can change the horizontal movement distance of the push plate. The larger the rotation radius of the sliding column, the greater the horizontal rightward movement distance of the push plate, and the more cotton is pushed into the ginning machine. By changing the movement distance of the push plate, the amount of cotton pushed can be changed, and the amount of cotton added can be precisely controlled to avoid adding too much or too little cotton.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example

[0026] Please see Figures 1 to 3 The present invention provides a technical solution including a main ginning machine 1. A second motor 14 is fixedly connected to one side of the middle of the rear surface of the ginning machine 1. One end of the output shaft of the second motor 14 passes through the ginning machine 1 and is fixedly connected to a drive shaft 2. One end of the drive shaft 2 passes through the ginning machine 1 and is connected to a belt 10. One end of the surface of the belt 10 is connected to a driven shaft 9. Both the drive shaft 2 and the driven shaft 9 are rotatably connected to the ginning machine 1. Both the surfaces of the drive shaft 2 and the driven shaft 9 are fixedly connected to a roller assembly 15 and a cutter assembly 16.

[0027] Specifically, closing the switch of the second motor 14 causes it to drive the drive shaft 2 to rotate. Due to the cooperation of the belt 10, it drives the driven shaft 9 to rotate, which in turn drives the roller assembly 15 and the cutter assembly 16 to rotate, so that they can process the cotton.

[0028] Please see Figures 4 to 5 A fixed plate 4 is fixedly connected to the middle of the front surface of the cotton gin 1. Elastic telescopic rods 5 are fixedly connected to both sides of the bottom end of the fixed plate 4. A U-shaped plate 11 is fixedly connected to the bottom end of the elastic telescopic rod 5. A transmission roller 12 is rotatably connected to the bottom end of the inner surface of the U-shaped plate 11. The transmission roller 12 is in contact with the belt 10. The transmission roller 12 is located at the midpoint of the length of the belt 10 and is symmetrically arranged with the axis of the drive shaft 2 and the driven shaft 9.

[0029] Specifically, when the belt 10 is working normally, the surface of the transmission roller 12 is in contact with the surface of the belt 10. Due to the cooperation of the second motor 14, the belt 10 rotates, creating tension on the surface of the belt 10. Due to the elasticity of the elastic telescopic rod 5, the tension on the surface of the belt 10 is balanced with the elastic force of the elastic telescopic rod 5, allowing the transmission roller 12 to be in contact with the surface of the belt 10. When the belt 10 becomes loose due to wear, the surface tension of the belt 10 decreases. Due to the elasticity of the elastic telescopic rod 5, the U-shaped plate 11 and the transmission roller 12 are coordinated to pull the belt 10 upward, so that the tension on the surface of the belt 10 is balanced with the elastic force of the elastic telescopic rod 5 again, keeping the belt 10 taut on the surfaces of the drive shaft 2 and the driven shaft 9.

[0030] Please refer to Figure 1 and Figure 3 The feed inlet of the cotton gin 1 is connected to an L-shaped feed box 6, and a protective box 7 is fixedly connected to the bottom of one side of the L-shaped feed box 6.

[0031] Specifically, it causes the cotton to be poured into the L-shaped feed box 6.

[0032] Please see Figure 1 , Figure 3 and Figure 6A first motor 13 is fixedly connected to the center of the rear surface of the protective box 7. One end of the output shaft of the first motor 13 passes through the protective box 7 and is fixedly connected to a rotating shaft 20. One end of the rotating shaft 20 is fixedly connected to a turntable 19. A screw hole 23 is opened on one side of the front surface of the turntable 19. The bottom end of the screw hole 23 passes through the turntable 19. There are multiple screw holes 23, which are linearly distributed along the radial direction of the turntable 19. A sliding post 22 is provided on the inner side of the screw hole 23. The surface of the sliding post 22 is provided with an external thread, which is threaded to the screw hole 23. The front of the turntable 19... The surface is provided with a sliding plate 21, and the front surface of the sliding plate 21 is provided with a sliding groove. The bottom end of the sliding groove passes through the sliding plate 21. The width of the sliding groove matches the diameter of the sliding column 22. The sliding column 22 is slidably connected to the sliding groove. The sliding plate 21 is slidably connected to the protective box 7. A connecting plate 18 is fixedly connected to one side of the sliding plate 21. A push plate 17 is fixedly connected to one end of the connecting plate 18. The push plate 17 is slidably connected to the protective box 7 and the L-shaped feed box 6. The horizontal movement path of the push plate 17 is parallel to the feed port axis of the L-shaped feed box 6. A box door 8 is rotatably connected to the front surface of the protective box 7.

[0033] Specifically, closing the switch of the first motor 13 causes the rotating shaft 20 and the turntable 19 to rotate the sliding column 22 around the rotating shaft 20. The sliding plate 21, the sliding groove, and the connecting plate 18 cause the push plate 17 to move horizontally to the left or right. The push plate 17 pushes the cotton in the L-shaped feed box 6 into the cotton ginning machine 1. If it is necessary to change the amount of cotton pushed into the cotton ginning machine 1, the door 8 of the protective box 7 is opened. The rotation radius of the sliding column 22 can be changed by the cooperation between the external thread on the surface of the sliding column 22 and the screw hole 23. The horizontal movement distance of the push plate 17 can be changed by the cooperation between the sliding groove, the sliding plate 21, and the connecting plate 18. The larger the rotation radius of the sliding column 22, the greater the horizontal movement distance of the push plate 17 to the right, and the more cotton is pushed into the cotton ginning machine 1.

[0034] In use, the cotton is poured into the L-shaped feed box 6. The switch of the first motor 13 is closed. Through the cooperation between the rotating shaft 20 and the turntable 19, the sliding column 22 rotates around the rotating shaft 20. Through the cooperation between the sliding plate 21, the sliding groove, and the connecting plate 18, the push plate 17 moves horizontally left or right. The push plate 17 pushes the cotton from the L-shaped feed box 6 into the cotton ginning machine 1. If it is necessary to change the amount of cotton pushed into the cotton ginning machine 1, the door 8 of the protective box 7 is opened. Through the cooperation between the external thread on the surface of the sliding column 22 and the screw hole 23, the rotation radius of the sliding column 22 can be changed. Through the cooperation between the sliding groove, the sliding plate 21, and the connecting plate 18, the horizontal movement distance of the push plate 17 can be changed. The larger the rotation radius of the sliding column 22, the greater the horizontal movement distance of the push plate 17 to the right, and the more cotton is pushed into the cotton ginning machine 1. The switch of the second motor 14 is closed, causing it to drive the drive shaft 2 to rotate. The belt 10 drives the driven shaft 9 to rotate, which in turn drives the roller assembly 15 and the cutter assembly 16 to rotate, allowing them to process cotton. When the belt 10 is working normally, the surface of the transmission roller 12 is in contact with the surface of the belt 10. Due to the cooperation of the second motor 14, the belt 10 rotates, creating tension on its surface. The elasticity of the elastic telescopic rod 5 keeps the tension on the surface of the belt 10 balanced with the elastic force of the elastic telescopic rod 5, allowing the transmission roller 12 to remain in contact with the surface of the belt 10. When the belt 10 becomes loose due to wear, the surface tension of the belt 10 decreases. Due to the elasticity of the elastic telescopic rod 5, the U-shaped plate 11, in conjunction with the transmission roller 12, pulls the belt 10 upward, causing the tension on the surface of the belt 10 to be balanced with the elastic force of the elastic telescopic rod 5 again, keeping the belt 10 taut on the surfaces of the drive shaft 2 and the driven shaft 9.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
