Description

Technical Field

[0001] This utility model relates to the technical field of cotton fiber pretreatment equipment, specifically to a cotton lint cleaning machine. Background Technology

[0002] The cotton cleaning machine is used to remove most large-particle impurities (such as infertile seeds and broken seed husks) from cotton lint, and loosen most of the loose fibers in the cotton lint, greatly improving the appearance of the cotton and increasing the ginning quality. In addition, because the adhesion between impurities and cotton lint is relatively small before compression into bales, the cotton cleaning machine can achieve high impurity removal efficiency, simplifying the cotton cleaning process in spinning and increasing the yarn yield of cotton lint.

[0003] The related technology discloses a cotton cleaning machine, which consists of a frame, a dust cage, a traction roller, a licker-in roller, a waste removal knife, and a cotton picking plate. The dust cage, traction roller, and licker-in roller are all rotatably connected to the frame. The two ends of the dust cage are connected to the dust discharge chamber through air ducts. Two traction rollers are arranged in parallel, and the two traction rollers are located below the dust cage and rotate in opposite directions. The traction roller that rotates in opposite directions to the dust cage is slidably connected to the outer wall of the dust cage. The licker-in roller is located below the traction roller. The waste removal knife is spaced apart from the outer wall of the licker-in roller, and the cotton picking plate is spaced apart from the outer wall of the licker-in roller.

[0004] The aforementioned technologies use two traction rollers to peel the cotton lint from the dust cage, and the resulting cotton wadding is directly hooked by the licker roller, making it difficult to achieve uniform hooking of the cotton lint, thus resulting in low cleaning efficiency. Utility Model Content

[0005] In view of this, the present invention provides a cotton cleaning machine to solve the problem that related technologies are difficult to achieve uniform hooking and pulling of cotton, resulting in low cleaning efficiency.

[0006] In a first aspect, this utility model provides a cotton cleaning machine, comprising:

[0007] A cotton collection assembly includes a housing and a dust cage rotatably disposed within the housing, the housing having a lint inlet;

[0008] A cotton stripping assembly, including a pressing roller and a stripping roller, is used to strip lint from the dust cage;

[0009] The cotton feeding assembly includes the pressing roller and the cotton feeding plate, wherein the cotton feeding plate is located below the stripping roller;

[0010] The cotton cleaning assembly includes a licker-in roller and a waste removal knife, wherein the waste removal knife is disposed on one side of the licker-in roller;

[0011] The cotton brushing assembly is located on the other side of the licker roller.

[0012] Beneficial Effects: Under the blowing of the airflow from the ginning machine's brushes or the brush bale, and the suction of the ginning machine's fan, the lint enters the housing through the lint inlet and is conveyed to the surface of the dust cage. The dust-laden airflow passes through the dust cage and is discharged into the dust chamber through the air duct inside the dust cage. The lint adsorbed on the dust cage rotates with the dust cage and is then peeled off by the pressing roller and the stripping roller, forming a uniform and continuous cotton wadding. The rotation of the pressing roller causes the cotton wadding to move around the pressing roller and enter between the pressing roller and the feed plate. As the cotton wadding passes through the feed plate and the pressing roller, it is evenly fed into the licker-in roller under the grip of the feed plate and the pressing roller, where it is hooked and combed. Due to the heavier defects of infertile seeds, natural impurities, and large particles, they are discharged under the action of centrifugal force and detached from the licker-in roller under the cutting impact of the impurity removal knife. The hooked fibers leave the licker-in roller through the brushing assembly. Because the pressing roller can simultaneously press the cotton and cooperate with the feeding plate to hold it, it provides a thinner and more uniform cotton layer to the licker-in roller for hooking and combing, resulting in high impurity removal efficiency, good appearance, reduced fiber damage, and improved cotton quality.

[0013] In one alternative embodiment, a first gap is formed between the pressing roller and the stripping roller, the first gap being located obliquely above the pressing roller, and a second gap is formed between the pressing roller and the feeding plate, the second gap extending below the pressing roller.

[0014] Beneficial effects: A first gap is formed between the pressing roller and the stripping roller. The first gap is located diagonally above the pressing roller. Therefore, the cotton wadding first passes diagonally above the pressing roller and, driven by the pressing roller, enters the second gap between the pressing roller and the feed plate. Since the second gap extends below the pressing roller, the cotton wadding finally flows out from below the pressing roller. The cotton wadding is equivalent to going around half a circle of the pressing roller. Therefore, it can uniformly press, stretch, and feed the cotton, providing a uniform cotton layer to the licker-in roller.

[0015] In one optional embodiment, the feeding plate includes a first arc portion and a second arc portion, the first arc portion forming a second gap with the pressing roller, and the second arc portion engaging with the stripping roller.

[0016] Beneficial effects: The first arc portion forms a second gap with the pressing roller, which allows for uniform pressing and stretching of the cotton. The gap between the second arc portion and the stripping roller prevents the cotton board from interfering with the rotation of the stripping roller, ensuring smooth rotation of the stripping roller.

[0017] In one alternative embodiment, the feed plate is located on the side of the pressing roller away from the waste removal knife.

[0018] Beneficial effects: By setting the feed plate on the side of the pressing roller away from the waste removal knife, the licker-in roller can hook the fiber in the same direction, avoiding damage to the fiber length. At the same time, it reduces the risk of cotton fiber blockage causing damage to the feed plate and reduces accidents.

[0019] In one alternative embodiment, the pressing roller is located directly below the dust cage.

[0020] Beneficial effects: Since the cotton pressing roller is located directly below the dust cage, while the cotton stripping roller and the cotton feeding plate are located on the same side of the cotton pressing roller, the cotton can be pressed, stretched, and fed more evenly, providing a uniform cotton layer to the licker-in roller.

[0021] In one alternative embodiment, the pressing roller is connected to a spring buffer device.

[0022] Beneficial effects: Because the pressing roller is connected to a spring buffer device, it can swing under the action of the spring buffer device, thereby adjusting the gap between the pressing roller, the stripping roller, and the feed plate. The pressing roller applies a certain pressure to the feed plate while maintaining a certain gap, ensuring that both the feed plate and the pressing roller can clamp the lint fibers tightly without clogging. Furthermore, when the cotton batting is thick, the pressing roller can push the spring buffer device, allowing the cotton batting to pass through smoothly and protecting the feed plate and the pressing roller.

[0023] In one optional embodiment, the diameter of the pressing roller is larger than the diameter of the stripping roller, wherein the diameter of the pressing roller is 100-300mm and the diameter of the stripping roller is 50-200mm.

[0024] Beneficial effects: Since the diameter of the pressing roller is larger than that of the stripping roller, it can work together with the stripping roller to press and strip cotton, forming a uniform cotton wadding. It also works with the feeding plate to hold the cotton, providing a thinner and more uniform cotton layer to the licker-in roller for hooking and combing, thus improving the appearance and quality of the lint.

[0025] In one optional embodiment, the brushing assembly is an airflow brushing assembly, including an air inlet and a lint outlet communicating with the air inlet. The air inlet faces the licker-in roller and is located downstream of the impurity removal knife along the rotation direction of the licker-in roller.

[0026] Beneficial Effects: Cotton, propelled by the airflow from the ginning machine brushes or the brush bale, and drawn in by the fan of the cotton cleaning machine, enters the casing through the cotton inlet and is conveyed to the surface of the dust cage. The dust-laden airflow passes through the dust cage and is discharged into the dust chamber through the air duct inside the dust cage. The cotton adsorbed on the dust cage rotates with the dust cage and is then peeled off by the pressing roller and the stripping roller, forming a uniform and continuous cotton wadding. The rotation of the pressing roller causes the cotton wadding to move around the pressing roller and enter between the pressing roller and the feeding plate. As the cotton wadding passes through the feeding plate and the pressing roller, it is evenly fed into the licker-in roller under the grip of the feeding plate and the pressing roller, where it is hooked and combed. Due to the heavier defects of infertile seeds, natural impurities, and large particles, they are discharged under the action of centrifugal force and detached from the licker-in roller under the cutting impact of the impurity removal knife. Air is blown into the licker-in roller through the air inlet, and the hooked fibers leave the licker-in roller under the action of the airflow and exit the cotton cleaning machine from the cotton outlet.

[0027] In one optional embodiment, an upper cover plate and a lower cover plate are respectively provided on the upper and lower sides of the cotton outlet. The lower cover plate is movably arranged, and the gap between the lower cover plate and the licker-in roller is adjacent to the air supply port.

[0028] Beneficial effects: Since the lower cover plate at the cotton outlet is movable, the distance between the lower cover plate at the cotton outlet and the licker-in roller can be adjusted, as can the air volume entering the cotton outlet.

[0029] In one alternative embodiment, the diameter or side length of the cotton inlet is 100-500 mm, and / or the diameter or side length of the cotton outlet is 100-400 mm. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] The cotton cleaning machine is used to remove most large-particle impurities (such as infertile seeds and broken seed husks) from cotton lint, and loosen most of the loose fibers in the cotton lint, greatly improving the appearance of the cotton and increasing the ginning quality. In addition, because the adhesion between impurities and cotton lint is relatively small before compression into bales, the cotton cleaning machine can achieve high impurity removal efficiency, simplifying the cotton cleaning process in spinning and increasing the yarn yield of cotton lint.

[0037] The related technology discloses a cotton cleaning machine, which consists of a frame, a dust cage, a traction roller, a licker-in roller, a waste removal knife, and a cotton picking plate. The dust cage, traction roller, and licker-in roller are all rotatably connected to the frame. The two ends of the dust cage are connected to the dust discharge chamber through air ducts. Two traction rollers are arranged in parallel, and the two traction rollers are located below the dust cage and rotate in opposite directions. The traction roller that rotates in opposite directions to the dust cage is slidably connected to the outer wall of the dust cage. The licker-in roller is located below the traction roller. The waste removal knife is spaced apart from the outer wall of the licker-in roller, and the cotton picking plate is spaced apart from the outer wall of the licker-in roller.

[0038] The aforementioned technologies use two traction rollers to peel the cotton lint from the dust cage, and the resulting cotton wadding is directly hooked by the licker roller, making it difficult to achieve uniform hooking of the cotton lint, thus resulting in low cleaning efficiency.

[0039] The following is combined Figures 1 to 2 The following describes embodiments of the present invention.

[0040] According to an embodiment of the present invention, a cotton cleaning machine is provided, comprising: a cotton collecting component, a cotton stripping component, a cotton feeding component, a cotton cleaning component, and a cotton brushing component.

[0041] The cotton collecting assembly includes a cover 1 and a dust cage 2 rotatably disposed within the cover 1, the cover 1 having a lint inlet 101; the cotton stripping assembly includes a pressing roller 3 and a stripping roller 4, the cotton stripping assembly being used to strip the lint from the dust cage 2; the cotton feeding assembly includes a pressing roller 3 and a feeding plate 5, the feeding plate 5 being disposed below the stripping roller 4; the cotton cleaning assembly includes a licker-in roller 8 and a waste removal knife 9, the waste removal knife 9 being disposed on one side of the licker-in roller 8; and the cotton brushing assembly being disposed on the other side of the licker-in roller 8.

[0042] In this embodiment, the lint is blown by the airflow from the brush of the ginning machine or the airflow from the brush bale, and drawn by the fan of the lint cleaning machine. It enters the housing 1 through the lint inlet 101 and is sent to the surface of the dust cage 2. The dust-laden airflow passes through the dust cage 2 and is discharged into the dust chamber through the air duct inside the dust cage 2. The lint adsorbed on the dust cage 2 rotates with the dust cage 2, and is then peeled off by the pressing roller 3 and the stripping roller 4 to form a uniform and continuous cotton wadding. The rotation of the pressing roller 3 drives the cotton wadding around the pressing roller 3 and into the space between the pressing roller 3 and the feeding plate 5. When the cotton wadding passes through the feeding plate 5 and the pressing roller 3, it is evenly fed into the licker-in roller 8 under the grip of the feeding plate 5 and the pressing roller 3, and is hooked and combed by the licker-in roller 8. Because infertile seeds, natural impurities and large particles are more severe, they are discharged under the action of centrifugal force and detached from the licker-in roller 8 under the cutting impact of the impurity removal knife 9. The hooked fibers leave the licker-in roller 8 through the brushing assembly. Because the pressing roller 3 can simultaneously press the cotton and cooperate with the feeding plate 5 to hold it, it provides a thinner and more uniform cotton layer to the licker-in roller 8 for hooking and combing, resulting in high cleaning efficiency, good appearance, reduced fiber damage, and improved cotton quality.

[0043] like Figure 1 As shown, the pressing roller 3, the stripping roller 4, and the feeding plate 5 form a triangular zone to uniformly press, stretch, and feed the cotton, providing a uniform cotton layer to the licker-in roller 8.

[0044] In one embodiment, such as Figure 2 As shown, a first gap 6 is formed between the pressing roller 3 and the stripping roller 4. The first gap 6 is located diagonally above the pressing roller 3. A second gap 7 is formed between the pressing roller 3 and the feeding plate 5. The second gap 7 extends to the bottom of the pressing roller 3.

[0045] In this embodiment, a first gap 6 is formed between the pressing roller 3 and the stripping roller 4. The first gap 6 is located obliquely above the pressing roller 3. Therefore, the cotton wadding first passes obliquely above the pressing roller 3 and enters the second gap 7 between the pressing roller 3 and the feeding plate 5 under the drive of the pressing roller 3. Since the second gap 7 extends to the bottom of the pressing roller 3, the cotton wadding finally flows out from the bottom of the pressing roller 3. The cotton wadding is equivalent to going around half a circle of the pressing roller 3, so the cotton can be pressed, stretched and fed evenly, providing a uniform cotton layer to the licker-in roller 8.

[0046] Specifically, such as Figure 1 and Figure 2 As shown, the first gap 6 is located diagonally above the right side of the pressing roller 3, and the second gap 7 is located diagonally below the right side of the pressing roller 3.

[0047] In one embodiment, the cotton feeding plate 5 includes a first arc portion and a second arc portion, the first arc portion forming a second gap 7 with the cotton pressing roller 3, and the second arc portion engaging with the cotton stripping roller 4.

[0048] In this embodiment, a second gap 7 is formed between the first arc portion and the pressing roller 3, so that the cotton can be pressed and stretched evenly. The second arc portion is fitted with the stripping roller 4 with a gap, so that the cotton plate 5 does not interfere with the rotation of the stripping roller 4, and the stripping roller 4 can be rotated smoothly.

[0049] In one embodiment, the cotton feeding plate 5 is located on the side of the cotton pressing roller 3 away from the waste removal knife 9.

[0050] In this embodiment, by setting the cotton feed plate 5 on the side of the cotton pressing roller 3 away from the waste removal knife 9, the licker-in roller 8 can hook the fiber in the same direction, avoiding damage to the fiber length. At the same time, it reduces the damage to the cotton feed plate 5 caused by cotton fiber blockage, thus reducing accidents.

[0051] In one embodiment, the pressing roller 3 is located directly below the dust cage 2.

[0052] In this embodiment, since the pressing roller 3 is located directly below the dust cage 2, and the stripping roller 4 and the feeding plate 5 are located on the same side of the pressing roller 3, the cotton can be pressed, stretched, and fed more evenly, providing a uniform cotton layer to the licker-in roller 8.

[0053] Specifically in one embodiment, such as Figure 1 As shown, the cotton cleaning machine includes an upper box 10 and a lower box 11. The cover 1 and the cotton stripping assembly are located in the upper box 10, while the licker-in roller 8 and the cotton brushing assembly are located in the lower box 11. The cover 1 includes a front cover assembly 102, a dust cage front door 103, an upper inlet plate assembly 104, a dust cage rear door 105, and a lower cover assembly 106. A cotton inlet 101 is formed between the top of the dust cage rear door 105 and the upper inlet plate assembly 104.

[0054] Specifically, such as Figure 1 As shown, a lower inlet plate assembly 107 is also provided below the upper inlet plate assembly 104, and the cotton inlet 101 is located between the upper inlet plate assembly 104 and the lower inlet plate assembly 107.

[0055] In one specific embodiment, multiple debris-removing blades 9 are provided. Figure 1 The CCP demonstrated six impurity removal knives, which can reduce damage to the length of cotton fibers.

[0056] In one specific embodiment, the bottommost debris discharge blade 9 is connected to a debris adjustment plate 12.

[0057] In one specific embodiment, the bottom of the box is provided with a chassis 13, and the lower end of the chassis 13 is provided with a support leg 14.

[0058] In one embodiment, the cotton feeding board 5 is an aluminum alloy board.

[0059] In this embodiment, the cotton feeding plate 5 is an aluminum alloy plate. The aluminum alloy material can prevent the cotton feeding roller from colliding with the cotton feeding plate 5 during operation and causing a fire.

[0060] In one embodiment, the pressing roller 3 is connected to a spring buffer device.

[0061] In this embodiment, because the pressing roller 3 is connected to a spring buffer device, the pressing roller 3 can swing under the action of the spring buffer device, thereby adjusting the gap between the pressing roller 3, the stripping roller 4, and the feeding plate 5. The pressing roller 3 applies a certain pressure to the feeding plate 5 while maintaining a certain gap, ensuring that both the feeding plate 5 and the pressing roller 3 can clamp the lint fibers without clogging. Furthermore, when the cotton batting is thick, the pressing roller 3 can push the spring buffer device, allowing the cotton batting to pass smoothly and protecting the feeding plate 5 and the pressing roller 3.

[0062] Specifically, the position of the cotton board 5 is fixed, and the cotton pressing roller 3 can swing under the action of the spring buffer device.

[0063] In one specific embodiment, one end of the spring buffer device is connected to the bearing frame, the cotton pressing roller 3 is disposed on the bearing frame, and after the cotton pressing roller 3 is assembled on the bearing frame, the position of the cotton pressing roller 3 is limited by the fixing frame. One end of the bearing frame is fixed, and the other end can swing under the action of the spring buffer device.

[0064] In one specific embodiment, a fixing frame is fixed inside the lower housing 11, and one end of the bearing bracket is fixed to the fixing frame.

[0065] In one specific embodiment, the spring buffer device includes a spring support, a spring, a piston, and a set screw. The spring support and the piston are slidable relative to each other, the spring is disposed between the spring support and the piston, and the set screw is used to adjust the spring pressure, thereby regulating and applying gripping force to the cotton board 5.

[0066] In one embodiment, the diameter of the pressing roller 3 is larger than the diameter of the stripping roller 4, with the diameter of the pressing roller 3 being 100-300mm and the diameter of the stripping roller 4 being 50-200mm.

[0067] In this embodiment, since the diameter of the pressing roller 3 is larger than that of the stripping roller 4, it can cooperate with the stripping roller 4 to press and strip cotton, forming a uniform cotton wadding. It also cooperates with the cotton feeding plate 5 to hold the cotton, providing a thinner and more uniform cotton layer to the licker-in roller 8 for hooking and combing, thereby improving the appearance and quality of the lint.

[0068] In one specific embodiment, the diameter of the pressing roller 3 is 100mm, and the diameter of the stripping roller 4 is 50mm.

[0069] In one specific embodiment, the diameter of the pressing roller 3 is 300 mm, and the diameter of the stripping roller 4 is 150 mm.

[0070] In one specific embodiment, the diameter of the pressing roller 3 is 200 mm, and the diameter of the stripping roller 4 is 100 mm.

[0071] In one embodiment, the cotton brushing assembly is an airflow cotton brushing assembly, including an air inlet 15 and a lint outlet 16 communicating with the air inlet 15. The air inlet 15 faces the licker roller 8 and is located downstream of the lint removal knife 9 along the rotation direction of the licker roller 8.

[0072] In this embodiment, the cotton lint is blown by the airflow from the brush of the ginning machine or the airflow from the brush bale, and drawn by the fan of the cotton cleaning machine. It enters the housing 1 through the cotton inlet 101 and is sent to the surface of the dust cage 2. The dust-laden airflow passes through the dust cage 2 and is discharged into the dust chamber through the air duct inside the dust cage 2. The cotton lint adsorbed on the dust cage 2 rotates with the dust cage 2, and is then peeled off by the pressing roller 3 and the stripping roller 4 to form a uniform and continuous cotton wadding. The rotation of the pressing roller 3 drives the cotton wadding to enter between the pressing roller 3 and the feeding plate 5. When the cotton wadding passes through the feeding plate 5 and the pressing roller 3, it is evenly fed into the licker-in roller 8 under the grip of the feeding plate 5 and the pressing roller 3, and is hooked and combed by the licker-in roller 8. Because infertile seeds, natural impurities, and large particles are heavily defective, they are discharged under the action of centrifugal force. Under the cutting and impact of the impurity removal knife 9, they are separated from the licker roller 8 and blown into the licker roller 8 through the air inlet 15. The hooked fibers leave the licker roller 8 under the action of the airflow and leave the cotton cleaning machine from the cotton outlet 16.

[0073] In other alternative embodiments, the brushing assembly may include a brush, and the cleaned cotton is brushed into the cotton outlet 16 when the licker roller 8 rotates to meet the brush.

[0074] In one embodiment, the upper and lower sides of the cotton outlet 16 are respectively provided with an upper cotton outlet cover plate 17 and a lower cotton outlet cover plate 18. The lower cotton outlet cover plate 18 is movably arranged, and the gap between the lower cotton outlet cover plate 18 and the licker roller 8 is adjacent to the air supply port 15.

[0075] In this embodiment, since the lower cover plate 18 of the cotton outlet is movable, the distance between the lower cover plate 18 of the cotton outlet and the licker roller 8 can be adjusted, as can the air volume entering the cotton outlet 16.

[0076] In one embodiment, the diameter or side length of the cotton inlet 101 is 100-500 mm, and / or the diameter or side length of the cotton outlet 16 is 100-400 mm.

[0077] In one specific embodiment, the cotton inlet 101 is square, and the side length of the cotton inlet 101 is 100mm.

[0078] In one specific embodiment, the cotton lint outlet 16 is square, and the side length of the cotton lint outlet 16 is 100mm.

[0079] In one embodiment, the outer surface of the pressing roller 3 is provided with multiple toothed grooves that extend axially; and / or, the outer surface of the stripping roller 4 is provided with multiple toothed grooves that extend axially.

[0080] In this embodiment, the outer surface of the pressing roller 3 is provided with multiple toothed grooves, which can increase the friction between the pressing roller 3 and the stripping roller 4, so as to better convey the cotton wadding downward; the outer surface of the stripping roller 4 is provided with multiple toothed grooves, which can improve the stripping effect.

[0081] Specifically, multiple V-shaped grooves are machined along the axial direction on the outer surface of the pressing roller 3, and multiple V-shaped grooves are machined along the axial direction on the outer surface of the stripping roller 4.

[0082] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
