Description

Technical Field

[0001] The present invention belongs to the technical field of textiles, and particularly relates to a cleaning device for drafting rollers of a spinning machine. Background Art

[0002] Spinning requires processes such as impurity removal, loosening, opening, carding, combing, drafting, twisting, and winding. However, during the spinning production process, sundries such as flying yarns and cotton hairs will adhere to the rollers of the spinning drafting device. The accumulation of these attachments will affect the normal operation of the components of the drafting device. Therefore, it is necessary to frequently clean these attachments such as flying yarns and cotton hairs.

[0003] For the cleaning of traditional drafting rollers of spinning machines, most of them require the rollers to be disassembled, and then the operators use brushes to manually clean the attachments on the rollers.

[0004] Such operations have low cleaning efficiency on the one hand. On the other hand, the flying fluffs and other floating objects brushed off create an extremely harsh working environment, causing great harm to the physical health of the operators. Moreover, in a closed operation space, the floating fluffs will also cause extreme safety hazards such as flash explosions.

[0005] Based on this, the present invention proposes a cleaning device for drafting rollers of a spinning machine. Summary of the Invention

[0036] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the relevant invention and not for limiting the invention. Additionally, it should be noted that for the sake of description, only parts related to the relevant invention are shown in the drawings.

[0037] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and embodiments.

[0038] In the first embodiment of the present invention, a drafting roller cleaning device for a spinning machine is proposed. The device includes:

[0039] A roller conveying device 1 for carrying and conveying the roller 4;

[0040] A roller cleaning device 2 for cleaning the surface of the roller 4 and disposed on a side of the roller 4 away from the roller conveying device 1;

[0041] The dust removal device 3 is used to collect the flying fluffs generated during the cleaning process.

[0042] In this embodiment, a U-shaped groove can be installed on the roller conveyor device 1, and the roller 4 is placed in the U-shaped groove to ensure the stability of the roller 4 when the roller cleaning device 2 cleans the roller 4 during the transmission process. A negative pressure device can also be integrated on the roller conveyor device 1 to firmly adsorb the roller 4 during transmission. The present invention does not make any limitation on the connection relationship between the roller 4 and the roller conveyor device 1, and all methods that can prevent the roller 4 from falling off the roller conveyor device 1 during cleaning are within the protection scope of the present invention.

[0043] For a clearer description of a drafting roller cleaning device of a spinning machine according to the present invention, the following is combined with Figures 1 - 8 Each device in the embodiment of the present invention is described in detail as follows:

[0044] As Figure 1 、 Figure 2 and Figure 7 shown, the roller conveyor device 1 is used to carry and convey the roller 4;

[0045] In this embodiment, the roller transmission device 1 includes a transmission belt 11, and the transmission belt 11 is drivingly connected to a driving device 12. The transmission belt 11 is used to transmit the roller 4.

[0046] Referring to Figure 3 In this embodiment, the driving device 12 includes a first rotating motor 121, a first transmission device 122, a first shaft 123, a third pulley 124, a fourth pulley 125, and a second shaft 126;

[0047] The first transmission device 122 can be a belt transmission device or a gear transmission device. Any transmission method is within the protection scope of the present invention. In this embodiment, only the belt transmission method is taken as an example, specifically:

[0048] The first transmission device 122 includes a first pulley 1221, a first conveyor belt 1222, and a second pulley 1223;

[0049] The housing of the first rotating motor 121 is fixed on the frame 14, which is fixed to the ground. The output shaft of the first rotating motor 121 is coaxially fixed with the first pulley 1221. The first pulley 1221 is connected to the second pulley 1223 by a first conveyor belt 1222 for belt drive. The second pulley 1223 is coaxially fixed with the first shaft 123. The first shaft 123 is mounted on the frame 14 by bearings. The first shaft 123 is coaxially fixed with the third pulley 124. The third pulley 124 is connected to the fourth pulley 125 by a transmission belt 11 for belt drive. The fourth pulley 125 is coaxially fixed with the second shaft 126. The second shaft 126 is mounted on the frame 14 by bearings.

[0050] The motion process of this embodiment is as follows:

[0051] First-stage transmission: After the first rotating motor 121 is started, its output shaft drives the coaxially fixed first pulley 1221 to rotate.

[0052] Belt transmission: The first pulley 1221 drives the second pulley 1223 to rotate synchronously through the first conveyor belt 1222.

[0053] Shaft linkage: The second pulley 1223 drives the first shaft 123 coaxially fixed with it to rotate. The first shaft 123 is supported on the frame 14 by bearings.

[0054] Second-stage transmission: The third pulley 124 at the end of the first shaft 123 rotates with the shaft and drives the fourth pulley 125 to rotate through the transmission belt 11.

[0055] Power output: The fourth pulley 125 drives the second shaft 126 coaxially fixed with it to rotate. The second shaft 126 is mounted on the frame 14 by bearings, and finally drives the transmission belt 11 to continuously move in a cycle to complete the conveying of the roller 4.

[0056] In this embodiment, the output shaft of the first rotating motor 121 can also be directly coaxially fixed with the third pulley 124. Those skilled in the art can choose any one of the two methods according to the specific layout of the device.

[0057] In this embodiment, a U-shaped groove can be installed on the roller conveying device 1, specifically, a U-shaped groove can be installed on the transmission belt 11.

[0058] In another way of this embodiment, grooves or protrusions are arranged at intervals on the transmission belt 11. The grooves or the protrusions are used to increase the friction coefficient between the transmission belt 11 and the roller 4. The roller 4 is placed on two adjacent protrusions or grooves.

[0059] The conveyor belt 11 is made of wear-resistant rubber material. The depth of the groove or the height of the protrusion is 2-10 mm, and the spacing is at least 1 / 3 of the diameter of the roller 4, ensuring that the roller 4 does not slip during transportation.

[0060] The first rotating motor 121 in this embodiment is a reduction motor, and those skilled in the art can set the rotation speed according to actual needs or the size of the roller 4.

[0061] As Figure 7 and Figure 8 shown, in this embodiment, the roller 4 is arranged in the card slot 5 and is rotatably connected to the card slot 5. The card slots 5 are arranged in an array in the conveying box 6, and the conveying box 6 is placed on the conveyor belt 11. Specifically, the card slot 5 is a semi-circular card slot 5 that matches the shape of the roller 4, and the card slot 5 has a clearance fit with the roller 4, enabling the roller 4 to rotate during cleaning;

[0062] In another way, a ball bearing can also be embedded in the inner wall of the card slot 5, so that the roller 4 can rotate freely. Using a ball bearing can reduce friction, avoid scratching the surface of the roller 4, and extend its service life;

[0063] In this embodiment, the rotation of the roller 4 along the card slot 5 can enable the roller cleaning device 2 to cover the surface by 360°, improving the cleaning efficiency.

[0064] Among them, at least one set of the third pulley 124, the conveyor belt 11, and the fourth pulley 125 can be arranged on the first shaft 123. When one set is arranged, the thickness of the third pulley 124 and the fourth pulley 125 and the width of the conveyor belt 11 should be greater than or equal to the width of the conveying box 6 to ensure the stability of the conveying box 6 during transportation.

[0065] Taking two sets as an example in this embodiment, the third pulley 124, the conveyor belt 11, and the fourth pulley 125 can be symmetrically arranged in two sets along the center of the first shaft 123. The conveying box 6 is placed on the two conveyor belts 11. Through the double-group symmetric conveyor belts 11, the unilateral force deviation can be offset, and the load-bearing capacity can be improved.

[0066] By setting the conveying box 6, continuous processing of a batch of rollers 4 can be realized, improving the production capacity of the device.

[0067] On the outer sides at both ends in the length direction of the conveyor belt 11, guide plates 13 are symmetrically installed. The inner side surface of the guide plate 13 forms an acute angle with the running direction of the conveyor belt 11. In other words, the guide plates 13 are two smooth plate pieces symmetrically arranged at both ends of the conveyor belt 11 along the conveying direction, and an inverted flared structure with a wider front and a narrower rear is formed between the two guide plates 13.

[0068] The guide plate 13 in this embodiment is a long metal plate with an L-shaped or straight cross-section. The guide plate 13 is symmetrically mounted on the frame 14 on both sides of the transmission belt 11 and fixed by bolts to ensure that the distance between the inner working surface and the belt edge is adjustable.

[0069] The inner working surface of the guide plate 13 forms an acute angle of 30°-45° with the running direction of the transmission belt 11, and guides the offset roller 4 to move toward the center of the transmission belt 11 through the inclined surface.

[0070] The inner working surface of the guide plate 13 is polished or affixed with a polymer wear-resistant material, and the friction coefficient is ≤0.15 to reduce the contact resistance of the roller 4. A spring buffer mechanism is provided at the bottom of the guide plate 13 to allow the roller 4 to produce elastic deformation when slightly squeezing the guide plate 13 to avoid jamming.

[0071] In this embodiment, a collecting plate for catching fallen fluff is provided at the lower part of the transmission belt 11, and the collecting plate is fixed to the frame 14. Specifically, the collecting plate is made of anti-static aluminum alloy or stainless steel plate, and the surface is polished or sprayed with Teflon coating to reduce the adhesion rate of flying fluff, and the edge is bent upward to form a 5-10mm guard to prevent the flying fluff from scattering laterally.

[0072] The plate surface of the collecting plate is designed to be a "V"-shaped or arc-shaped depression with a low middle and high sides, so as to guide the flying catkins to gather in the middle. A chip discharge port is provided at the bottom of the depression to connect to a dust collecting device.

[0073] The collecting plate adopts a segmented design, with a single segment length of 1-1.5m. The segments are connected by plug-in slots or lap buckles to adapt to belts of different lengths.

[0074] Threaded holes are reserved at both ends of the collecting plate, and side baffles can be installed for further sealing.

[0075] A leather roller cleaning device 2, used for cleaning the surface of the leather roller 4, and arranged on a side of the leather roller 4 away from the leather roller conveying device 1;

[0076] The roller cleaning device 2 includes a brush assembly 21 , and the brush assembly 21 is rotationally driven by a driving mechanism 22 .

[0077] In this embodiment, the roller 4 is arranged on the side away from the roller conveying device 1, specifically, see Figure 1 The leather roller cleaning device 2 is arranged above the leather roller 4.

[0078] See also Figure 4 In this embodiment, the driving mechanism 22 includes a second rotating motor 221, a second transmission device 222 and a third shaft 223;

[0079] The second transmission device 222, like the first transmission device 122, can be set to a belt drive mode or a gear drive mode. Any of these drive modes is within the scope of protection of the present invention. In this embodiment, only the belt drive mode is taken as an example for illustration:

[0080] The second transmission device 222 includes a fifth pulley 2221, a second conveyor belt 2222, and a sixth pulley 2223;

[0081] The housing of the second rotary motor 221 is fixed to the frame 14. The output shaft of the second rotary motor 221 is coaxially fixed to the fifth pulley 2221. The fifth pulley 2221 is belt-drivenly connected to the sixth pulley 2223 through the second conveyor belt 2222. The sixth pulley 2223 is coaxially fixed to the third shaft 223. The third shaft 223 is bearing-connected to the frame 14. The brush assembly 21 is arranged along the length direction of the third shaft 223 and is coaxially fixed to the third shaft 223.

[0082] In this embodiment, in order to ensure the stability of transmission, a tension pulley 2224 is arranged between the fifth pulley 2221 and the sixth pulley 2223.

[0083] In addition, in order to ensure the cleaning efficiency and effect, two sets of the third shaft 223 and the sixth pulley 2223 are arranged along the transmission direction of the leather roller 4, and two sets of tension pulleys 2224 are correspondingly arranged. Two sixth pulleys 2223, the second conveyor belt 2222, two tension pulleys 2224, and the fifth pulley 2221 together constitute the second transmission device 222.

[0084] The brush assembly 21 includes at least two kinds of brushes with different diameters and is spacedly distributed on the third shaft 223. The brushes have a brush surface with high and low levels, and the height of the brush surface is adapted to the surface contour of the leather roller 4.

[0085] Among them, the second rotary motor 221 can also be directly drive-connected to the third shaft 223. Those skilled in the art can arbitrarily select different drive modes according to the actual arrangement of parts, and the present invention does not make specific limitations.

[0086] See Figure 5 , in this embodiment, the first brush 211 and the second brush 212 are alternately installed on the third shaft 223; the diameter of the first brush 211 is larger than that of the second brush 212.

[0087] Among them, the first brush 211 is made of a flexible material that is a composite of nylon filaments and carbon fibers and is responsible for removing large pieces of flying floc on the surface of the leather roller 4;

[0088] The flexible material combined with the large-diameter design can efficiently remove large pieces of flying flocs on the surface of the roller 4, while avoiding damage to the rubber surface layer of the roller 4; it has a wide coverage area and significantly reduces surface residues.

[0089] The second brush 212 is made of a hard material that is a mixture of stainless steel wire and nylon, and it penetrates into the grooves of the roller 4 to clean the residual fibers. The hard metal wire penetrates into complex structures such as the grooves of the roller 4 to remove fine fibers that are difficult to reach by traditional brushes;

[0090] The mixed material reduces electrostatic adsorption during the cleaning process and reduces the risk of secondary pollution.

[0091] The flexible combination of nylon and carbon fiber reduces surface friction and reduces wear of the roller 4; the stainless steel wire is buffered by nylon coating to relieve contact impact and avoid direct scratching of the roller 4 by the metal. The uneven brush surface adapts to the concave and convex contours of the roller 4 to ensure no dead corners in cleaning.

[0092] The brush assembly 21 is connected to the third shaft 223 through a keyway and is axially fixed by a circlip.

[0093] In this embodiment, the key connection method is used. On the one hand, it can provide high torsional resistance to ensure the stability of the brush during high-speed cleaning. On the other hand, it supports quick disassembly and assembly, simplifies the brush replacement process; damaged brushes can be replaced specifically to avoid overall scrapping and reduce the consumable cost.

[0094] The dust removal device 3 is used to collect the flying flocs generated during the cleaning process.

[0095] In this embodiment, the dust removal device 3 includes a dust collection cover 31 and a dust collector 32;

[0096] The dust collection cover 31 is sleeved outside the roller cleaning device 2 and is fixed to the frame 14;

[0097] The dust collector 32 is hermetically connected to the dust collection cover 31, and the dust collector 32 is used to suck the cleaned flying flocs into the dust collector 32.

[0098] In this embodiment, the dust collection cover 31 has an inverted funnel-shaped structure that is narrow at the top and wide at the bottom. The brush assembly 21 is arranged at the lower opening of the dust collection cover 31. The narrow upper opening of the dust collection cover 31 is connected to the dust collector 32 to collect and transfer the cleaned flying flocs to the dust collector 32.

[0099] In the present invention, through the dust collection cover 31 with an inverted funnel structure, the cross-section gradually shrinks, so that the air flow velocity increases from the bottom to the top, forming a high-speed air flow, enhancing the flying floc carrying capacity, generating a low-pressure area at the narrow outlet, strengthening the suction force on the flying flocs, and preventing them from escaping to the external environment.

[0100] The lower wide-mouth design covers the entire cleaning area of the top roller 4, ensuring that 100% of the flying flocs generated during the rotation of the brush are incorporated into the cover. Additionally, the inclined surface of the funnel guides the flying flocs to converge towards the top outlet, preventing the flying flocs from accumulating disorderly inside the cover and reducing secondary dust generation.

[0101] See Figure 1 , the dust collector 32 includes a flying floc collection device 321 and a fan 322;

[0102] One end of the flying floc collection device 321 is hermetically connected to the dust collection cover 31 through a diversion channel 323, the other end of the flying floc collection device 321 is connected to the fan 322, and the fan 322 exhausts air outwards to ensure the formation of a directional air flow flowing from the dust collection cover 31 to the flying floc collection device 321 inside the diversion channel 323.

[0103] The fan 322 exhausts the air inside the flying floc collection device 321, creating a low pressure inside the flying floc collection device 321. Utilizing the pressure difference, a fixed negative pressure is formed inside the dust collection cover 31 and the diversion channel 323, forming a directional air flow flowing from the dust collection cover 31 to the flying floc collection device 321. The cotton and hair flying flocs brushed out by the brush assembly 21 are sent into the flying floc collection device 321 for collection along with the directional air flow.

[0104] Among them, the fan 322 can be an axial flow fan or an exhaust fan, and the present invention does not make specific limitations.

[0105] Among them, the diversion channel 323 can be a flexible pipe or a segmented steel pipe.

[0106] Both ends of the flexible pipe are provided with quick-install flanges, which are bolted and fastened to the dust collection cover 31 and the flying floc collection device 321. The bolt pre-tightening force ≥ 20 N·m to ensure the airtightness of the interface. The flange surface is processed with a sealing groove and a high-temperature resistant silica gel pad is embedded;

[0107] The outlet of the diversion channel 323 is processed into a 30° conical surface, which is in interference fit with the inlet conical sleeve of the flying floc collection device 321, and the interference amount is 0.1 - 0.2 mm; the mating surface is coated with sealant, and a secondary seal is formed after curing.

[0108] A dust cleaning door is provided at a set distance at the bottom of the diversion pipeline, with a quick-opening handle; it is opened during dust cleaning, and external air flow is sucked in using negative pressure to blow the accumulated dust.

[0109] In this embodiment, for the long-distance diversion channel 323, 2 fans 322 can be connected in parallel, and the air volume is balanced through a damper. When one fails, the other automatically switches to full-load operation.

[0110] In this embodiment, a turbulence generating device is provided inside the diversion channel 323, and the turbulence generating device includes at least one fixed component with turbulence characteristics.

[0111] Among them, the fixed component with spoiler characteristics includes a deflector or a spiral deflector.

[0112] The deflector is installed on the inner wall of the pipeline through a rotating shaft, and the external handle can adjust the inclination angle;

[0113] When the flying flocs are prone to agglomeration in a high-humidity environment, the inclination angle is increased to 45° to enhance the crushing effect; in a dry environment, it is adjusted to 15° to reduce energy consumption.

[0114] The spiral deflector is spirally wound around the inner wall of the pipeline. The length of each section of the spiral plate is 500 mm, and it is connected by flange bolts to adapt to pipelines of different lengths; the spiral directions of adjacent sections are opposite, one is left-handed and the other is right-handed, enhancing the turbulence effect.

[0115] See Figure 5 , in this embodiment, a plurality of wedge-shaped guide blocks 311 are provided at the front lower edge of the dust collection hood 31. The guide blocks 311 are fixed on the frame 14. The guide blocks 311 can adjust the position of the conveying roller 4 and ensure that the brush assembly 21 corresponds to the groove of the roller 4.

[0116] The inclined surface design of the wedge-shaped guide block 311 of the present invention guides the roller 4 to automatically center when entering the cleaning station, ensuring that the axis of the roller 4 is precisely aligned with the rotation axis of the brush assembly 21; the tip of the brush can be completely embedded in the surface groove of the roller 4, avoiding cleaning blind spots caused by position deviation.

[0117] The position of the guide block 311 in this embodiment can be finely adjusted to adapt to different models of rollers 4 with different groove spacings, improving the cleaning coverage rate.

[0118] See Figure 6 , in this embodiment, the first rotating motor 121, the second rotating motor 221 and the fan 322 are all electrically connected to the electric control box 15. The electric control box 15 coordinates and controls the operation of the first rotating motor 121, the second rotating motor 221 and the fan 322 through an automated program: when starting, the fan 322 is preferentially turned on to establish negative pressure, then the second rotating motor 221 is started and the rotation speed is adjusted, and finally the first rotating motor 121 is operated to match the conveying speed of the roller 4; during operation, the brush rotation speed and the belt speed are dynamically synchronized to ensure the cleaning effect, and at the same time, the fan power is automatically adjusted according to the pressure difference of the dust removal system to maintain a stable air flow; when stopping, the equipment is turned off in the reverse order, and safety protection mechanisms such as overload and high temperature are equipped. The status can be monitored in real time and the parameters can be adjusted through the touch screen to achieve the coordinated and efficient operation of the three motors.

[0119] In the second embodiment of the present invention, another cleaning device for the drafting roller of a spinning machine is proposed. On the basis of the first embodiment, a spray device is added. Specifically:

[0120] In view of the application characteristics of the present invention, the cotton and wool fluff cleared will float everywhere due to its light weight. On the one hand, it makes the operating environment air poor, seriously affecting the physical health of on-site operators. On the other hand, these floating fiber materials are extremely prone to combustion and explosion, posing serious safety hazards.

[0121] The drafting roller cleaning device of the spinning machine of the present invention can also target the drying and moisture absorption characteristics of this fluff. By adding a spray device in the dust collection hood 31, by maintaining the humidity of the cleaning environment and maintaining an appropriate amount of mist, and using the moisture absorption characteristics of the cotton and wool fluff, after the cotton and wool fluff absorbs moisture, its specific gravity increases and it is difficult to float.

[0122] On the basis of utilizing the increase in weight of the cotton and wool fluff due to moisture absorption, the directional air flow formed by the dust collection hood 31 and the directional fan 322 is used to send these cotton and wool fluff to the dust collector for collection and treatment.

[0123] The spray device includes a mist nozzle and a mist generator arranged in the dust-proof hood.

[0124] The mist generator can be an ultrasonic mist generator or an electric heating mist generator.

[0125] In the third embodiment of the present invention, another drafting roller cleaning device of the spinning machine is proposed. On the basis of the first embodiment, a group of air inlets are arranged on the side shell of the dust collection hood 31. The axial direction of the air inlets has the same included angle with the vertical central axis of the dust collection hood 31. The air flow of each air inlet enters the dust collection hood 31 at a certain included angle with the vertical central axis of the dust collection hood 31, and can act together to cause a rotating air flow centered on the vertical central axis of the dust collection hood 31 to be formed in the dust collection hood 31. Combined with the directional fan 322, a directional rotating air flow in the dust removal environment is jointly formed, which can further improve the effect of air flow dust removal.
