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 forward feeding device for a cotton cleaning machine, including a dust cage connected to a cotton inlet pipe, a pressing roller and a stripping roller arranged side by side below the dust cage in a relatively rotating manner, a drafting roller and a drafting smooth roller arranged side by side below the pressing roller and the stripping roller in a relatively rotating manner, a feeding roller and a feeding plate located between the drafting roller and the drafting smooth roller and above a toothed roller, a dust bar is provided on one side of the toothed roller and a brush roller is provided on the other side, the toothed roller and the brush roller cooperate in a counter-rotating manner, a cotton conveying pipe is connected above the brush roller, and a waste removal area is located outside the location of the dust bar, the waste removal pipe is located below the waste removal area, wherein the feeding roller and the toothed roller below it rotate in opposite directions, and the feeding plate is located in front of the feeding roller and the cotton being gripped.

[0004] In the aforementioned related technologies, the cotton stripping assembly, composed of the pressing roller and the stripping roller, is connected to the cotton feeding assembly, composed of the feeding roller and the feeding plate, by a drafting roller and a drafting light roller. This complex structure results in a large overall size and high cost for the cotton cleaning machine. Utility Model Content

[0005] In view of this, the present invention provides a cotton cleaning machine to solve the problem of complex structure of cotton cleaning machines in related technologies.

[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] A cotton feeding assembly is located below the cotton stripping assembly, and the cotton feeding assembly includes a cotton feeding roller and a cotton feeding plate;

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

[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 cleaning machine's fan, the cotton lint enters the housing through the cotton inlet and is sent 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 lint adsorbed on the dust cage rotates with the dust cage and is then peeled off by the pressing roller and the peeling roller, forming a uniform and continuous cotton wadding. The cotton feeding assembly includes a feeding roller and a feeding plate. The cotton feeding assembly is located below the peeling assembly. Therefore, when the cotton wadding passes through the feeding plate and the feeding roller, it is evenly fed into the licker-in roller under the grip of the feeding plate and the feeding 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. By positioning the feed plate on the side of the feed roller away from the waste removal knife, the licker-in roller can hook the fibers in the same direction, avoiding damage to the fiber length. This also reduces the risk of cotton fiber blockage causing damage to the feed plate and minimizes accidents. Furthermore, since the feed assembly is located below the stripping assembly, compared to related technologies, the drafting roller and drafting smooth roller are omitted, resulting in a simpler structure while still achieving proper gripping of the cotton wadding.

[0013] 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.

[0014] 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 peeling roller, forming a uniform and continuous cotton wadding. The cotton feeding assembly includes a feeding roller and a feeding plate, located below the peeling assembly. Therefore, when the cotton wadding passes through the feeding plate and the feeding roller, it is evenly fed into the licker-in roller under the grip of the feeding plate and the feeding 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 onto 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.

[0015] 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.

[0016] 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.

[0017] In one optional embodiment, the outer surface of the pressing roller is provided with a plurality of toothed grooves, the toothed grooves extending axially;

[0018] And / or, the outer surface of the stripping roller is provided with multiple toothed grooves, which extend axially.

[0019] Beneficial effects: The outer surface of the pressing roller has multiple grooves, which can increase the friction between the pressing roller and the stripping roller, so as to better convey the cotton wadding downward; the outer surface of the stripping roller has multiple grooves, which can improve the stripping effect.

[0020] In one alternative embodiment, the outer diameters of the pressing roller and the stripping roller are the same, and the outer diameter of the feeding roller is smaller than that of the pressing roller.

[0021] Beneficial effects: The outer diameters of the pressing roller and the stripping roller are the same, while the outer diameter of the feeding roller is smaller than that of the pressing roller. The relatively large outer diameters of the pressing roller and the stripping roller enable pressing and stripping of cotton to form a uniform cotton wadding. The relatively small outer diameter of the feeding roller allows it to grip the cotton on the feeding plate, providing a thinner cotton layer for the licker-in roller to hook and comb, thus improving the appearance and quality of the lint.

[0022] In one optional embodiment, the outer diameter of the pressing roller and the stripping roller is 100-200 mm, and the outer diameter of the feeding roller is 50-200 mm.

[0023] In one optional embodiment, a windproof device with openings at the top and bottom is provided between the cotton stripping assembly and the cotton feeding assembly.

[0024] Beneficial effect: By setting up a windproof device with openings at the top and bottom between the cotton stripping component and the cotton feeding component, the cotton wadding can fall more stably between the cotton feeding roller and the cotton feeding plate.

[0025] In one alternative embodiment, the cotton feeding roller is connected to a spring buffer device.

[0026] Beneficial effects: The cotton feeding roller can swing under the action of the spring buffer device. The cotton feeding roller applies a certain pressure to the cotton feeding plate while maintaining a certain gap. Both the cotton feeding plate and the cotton feeding roller can clamp the cotton fibers without clogging. Furthermore, when the cotton batting is thick, the cotton feeding roller can push the spring buffer device, thereby allowing the cotton batting to pass through smoothly and protecting the cotton feeding plate and the cotton feeding roller.

[0027] In one alternative implementation, the area below the cotton lint inlet communicates with the space on one side of the dust cage.

[0028] Beneficial effects: The space below the cotton lint inlet is connected to the space on one side of the dust cage, and the space below the cotton lint inlet is open, which can solve the problem of cotton lint returning and clogging.

[0029] In one alternative embodiment, the linear velocity of the licker roller is 25 m / s to 45 m / s.

[0030] Beneficial effects: The increased linear speed of the lickering roller greatly increases the centrifugal force on infertile seeds, natural impurities, and large particle defects, thereby improving the cleaning efficiency and the impurity removal effect. Attached Figure Description

[0037] 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.

[0038] 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.

[0039] The related technology discloses a forward feeding device for a cotton cleaning machine, including a dust cage connected to a cotton inlet pipe, a pressing roller and a stripping roller arranged side by side below the dust cage in a relatively rotating manner, a drafting roller and a drafting smooth roller arranged side by side below the pressing roller and the stripping roller in a relatively rotating manner, a feeding roller and a feeding plate located between the drafting roller and the drafting smooth roller and above a toothed roller, a dust bar is provided on one side of the toothed roller and a brush roller is provided on the other side, the toothed roller and the brush roller cooperate in a counter-rotating manner, a cotton conveying pipe is connected above the brush roller, and a waste removal area is located outside the location of the dust bar, the waste removal pipe is located below the waste removal area, wherein the feeding roller and the toothed roller below it rotate in opposite directions, and the feeding plate is located in front of the feeding roller and the cotton being gripped.

[0040] In the aforementioned related technologies, the cotton stripping assembly, composed of the pressing roller and the stripping roller, is connected to the cotton feeding assembly, composed of the feeding roller and the feeding plate, by a drafting roller and a drafting light roller. This complex structure results in a large overall size and high cost for the cotton cleaning machine.

[0041] The following is combined with Figures 1 to 3 The following describes embodiments of the present invention.

[0042] 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.

[0043] The cotton collecting assembly includes a housing 1 and a dust cage 2 rotatably disposed within the housing 1, the housing 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 is disposed below the cotton stripping assembly, the cotton feeding assembly including a feeding roller 5 and a feeding plate 6; the cotton cleaning assembly includes a licker-in roller 7 and a waste removal knife 8, the waste removal knife 8 being disposed on one side of the licker-in roller 7, the cotton feeding plate 6 being disposed on the side of the feeding roller 5 away from the waste removal knife 8; the cotton brushing assembly is disposed on the other side of the licker-in roller 7.

[0044] In this embodiment, the lint is blown by the airflow from the ginning machine brush or 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 fed 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, forming a uniform and continuous cotton wadding. The cotton feeding assembly includes a feeding roller 5 and a feeding plate 6. The cotton feeding assembly is located below the stripping assembly. Therefore, when the cotton wadding passes through the feeding plate 6 and the feeding roller 5, it is evenly fed into the licker-in roller 7 under the grip of the feeding plate 6 and the feeding roller 5, and is hooked and combed by the licker-in roller 7. Because infertile seeds, natural impurities, and large particles are heavier, they are discharged under the action of centrifugal force and detached from the licker-in roller 7 under the cutting impact of the impurity removal knife 8. The hooked fibers leave the licker-in roller 7 through the brushing assembly. By positioning the feed plate 6 on the side of the feed roller 5 away from the discharge knife 8, the licker-in roller 7 can hook the fibers in the same direction, avoiding damage to the fiber length. This also reduces the risk of cotton fiber blockage causing damage to the feed plate 6 and minimizes accidents. Furthermore, since the feed assembly is located below the stripping assembly, compared to related technologies, the drafting roller and drafting smooth roller are omitted, resulting in a simpler structure while still achieving proper gripping of the cotton wadding.

[0045] Specifically in one embodiment, such as Figure 1 As shown, the licker-in roller 7 rotates counterclockwise, the cotton feeding assembly is located on top of the licker-in roller 7, and the cotton feeding plate 6 is located to the right of the cotton feeding roller 5.

[0046] Specifically, such as Figure 2As shown, the cotton feeding plate 6 has an arc surface 601. The arc surface 601 and the cotton feeding roller 5 hold the cotton batting. The lower end of the arc surface 601 is the nose tip of the cotton feeding plate 6. The licker-in roller 7 hooks the fiber in the same direction to avoid damaging the fiber length. At the same time, it reduces the damage to the cotton feeding plate 6 caused by cotton fiber blockage and reduces accidents.

[0047] Specifically in one embodiment, such as Figure 1 As shown, the cotton cleaning machine includes an upper box 9 and a lower box 10. The cover 1 and the cotton stripping assembly are located in the upper box 9, while the licker-in roller 7 and the cotton brushing assembly are located in the lower box 10. 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.

[0048] In one specific embodiment, a roller scraper 11 is provided on the same side of the stripping roller 4 and the feeding plate 6, and the roller scraper 11 contacts the stripping roller 4 and the feeding plate 6.

[0049] In one specific embodiment, multiple debris-removing blades 8 are provided. Figure 1 The CCP demonstrated six impurity removal blades, which can reduce damage to the length of cotton fibers.

[0050] In one specific embodiment, the lowest debris discharge blade 8 is connected to a debris adjustment plate 12.

[0051] 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.

[0052] In one embodiment, the cotton feeding board 6 is an aluminum alloy board.

[0053] In this embodiment, the cotton feeding plate 6 is an aluminum alloy plate. The aluminum alloy material can prevent the cotton feeding roller 5 from colliding with the cotton feeding plate 6 during operation and causing a fire.

[0054] In one embodiment, the brushing assembly is an airflow brushing assembly, including an air inlet 19 and a lint outlet 20 communicating with the air inlet 19. The air inlet 19 faces the licker-in roller 7 and is located downstream of the sludge removal knife 8 along the rotation direction of the licker-in roller 7.

[0055] 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 peeling roller 4 to form a uniform and continuous cotton wadding. The cotton feeding assembly includes a cotton feeding roller 5 and a cotton feeding plate 6. The cotton feeding assembly is located below the cotton peeling assembly. Therefore, when the cotton wadding passes through the cotton feeding plate 6 and the cotton feeding roller 5, it is evenly fed into the licker-in roller 7 under the grip of the cotton feeding plate 6 and the cotton feeding roller 5, and is hooked and combed by the licker-in roller 7. Because infertile seeds, natural impurities, and large particles are heavily defective, they are discharged under centrifugal force. Under the cutting and impact of the impurity removal knife 8, they are separated from the licker roller 7 and blown into the licker roller 7 through the air inlet 19. The hooked fibers leave the licker roller 7 under the action of the airflow and leave the cotton cleaning machine from the cotton outlet 20.

[0056] In other alternative embodiments, the brushing assembly may include a brush, which brushes the cleaned cotton into the cotton outlet 20 when the licker roller 7 rotates to meet the brush.

[0057] In one embodiment, the upper and lower sides of the cotton outlet 20 are respectively provided with an upper cotton outlet cover plate 21 and a lower cotton outlet cover plate 22. The lower cotton outlet cover plate 22 is movably arranged, and the gap between the lower cotton outlet cover plate 22 and the licker roller 7 is adjacent to the air supply port 19.

[0058] In this embodiment, since the lower cover plate 22 of the cotton outlet is movable, the distance between the lower cover plate 22 of the cotton outlet and the licker roller 7 can be adjusted, as can the air volume entering the cotton outlet 20.

[0059] 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 20 is 100-400 mm.

[0060] In one specific embodiment, the cotton inlet 101 is square, and the side length of the cotton inlet 101 is 100mm.

[0061] In one specific embodiment, the cotton lint outlet 20 is square, and the side length of the cotton lint outlet 20 is 100mm.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] In one embodiment, the outer diameters of the pressing roller 3 and the stripping roller 4 are the same, while the outer diameter of the feeding roller 5 is smaller than that of the pressing roller 3.

[0066] In this embodiment, the outer diameters of the pressing roller 3 and the stripping roller 4 are the same, while the outer diameter of the feeding roller 5 is smaller than that of the pressing roller 3. The outer diameters of the pressing roller 3 and the stripping roller 4 are relatively large, which can achieve pressing and stripping of cotton to form a uniform cotton wadding. The outer diameter of the feeding roller 5 is relatively small, which allows it to grip the feeding plate 6 and provide a thinner cotton layer to the licker-in roller 7 for hooking and combing, thereby improving the appearance and quality of the lint.

[0067] In one embodiment, the outer diameter of the pressing roller 3 and the stripping roller 4 is 100-200 mm, and the outer diameter of the feeding roller 5 is 50-200 mm.

[0068] In one specific embodiment, the outer diameters of the pressing roller 3 and the stripping roller 4 are 200 mm, and the outer diameter of the feeding roller 5 is 100 mm.

[0069] In one specific embodiment, the outer diameters of the pressing roller 3 and the stripping roller 4 are 100 mm, and the outer diameter of the feeding roller 5 is 50 mm.

[0070] In one embodiment, a windproof device with openings at the top and bottom is provided between the cotton stripping assembly and the cotton feeding assembly.

[0071] In this embodiment, by providing a windproof device with openings at the top and bottom between the cotton stripping assembly and the cotton feeding assembly, the cotton wadding can fall more stably between the cotton feeding roller 5 and the cotton feeding plate 6.

[0072] Specifically, the wind shelter can consist of a steel structure and rubber sheets fixed to the steel structure.

[0073] In one embodiment, a spring buffer device 15 is connected to the cotton roller 5.

[0074] In this embodiment, the cotton feeding roller 5 can swing under the action of the spring buffer device 15. The cotton feeding roller 5 applies a certain pressure to the cotton feeding plate 6 while maintaining a certain gap. Both the cotton feeding plate 6 and the cotton feeding roller 5 can clamp the cotton fibers without clogging. Furthermore, when the cotton batting is thick, the cotton feeding roller 5 can push the spring buffer device 15, thereby allowing the cotton batting to pass through smoothly and protecting the cotton feeding plate 6 and the cotton feeding roller 5.

[0075] Specifically, the position of the cotton feeding plate 6 is fixed, and the cotton feeding roller 5 can swing under the action of the spring buffer device 15.

[0076] In one specific embodiment, one end of the spring buffer device 15 is connected to the bearing frame 16, and the cotton feeding roller 5 is disposed on the bearing frame 16. After the cotton feeding roller 5 is assembled on the bearing frame 16, the position of the cotton feeding roller 5 is limited by the bearing cover 17 and the fixing frame 18. One end of the bearing frame 16 is fixed, and the other end can swing under the action of the spring buffer device 15.

[0077] In one specific embodiment, a fixing frame 18 is fixed inside the lower housing 10, and one end of the bearing bracket 16 is fixed to the fixing frame 18.

[0078] Specifically in one embodiment, such as Figure 3 As shown, the spring buffer device 15 includes a spring bracket 1501, a spring 1502, a piston 1503, and a set screw 1504. The spring bracket 1501 and the piston 1503 can slide relative to each other. The spring 1502 is disposed between the spring bracket 1501 and the piston 1503. The set screw 1504 is used to adjust the pressure of the spring 1502, thereby regulating and applying gripping force to the cotton board 6.

[0079] In one embodiment, the space below the cotton inlet 101 is connected to the space on one side of the dust cage 2.

[0080] In this embodiment, the space below the cotton inlet 101 is connected to the space on one side of the dust cage 2, and the space below the cotton inlet 101 is open, which can solve the problem of cotton return and blockage.

[0081] It should be noted that if the bottom of the cotton inlet 101 is closed, cotton will easily get clogged at the inlet when returning cotton, requiring manual removal of the cotton. In this embodiment, the bottom of the cotton inlet 101 is open, so the cotton is still adsorbed outside the dust cage 2 when returning cotton, thus solving the problem of cotton clogging during cotton return.

[0082] In one embodiment, the linear velocity of the licker roller 7 is 25 m / s to 45 m / s.

[0083] In this embodiment, the increased linear speed of the licker roller 7 greatly increases the centrifugal force on infertile seeds, natural impurities, and large particle defects, thereby improving the cleaning efficiency and the impurity removal effect.

[0084] In one specific embodiment, the rotational speed of the licker roller 7 is 1800 rpm, which is significantly higher than the 1100 rpm rotational speed of the licker roller 7 in the cotton cleaning machine in the related art, thus improving the cleaning efficiency and the impurity removal effect.

[0085] 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.
