Description

A cleaning device for the drafting roller of a spinning machine Technical Field

[0001] This utility model belongs to the field of textile technology, and specifically relates to a cleaning device for the drafting roller of a spinning machine. Background Technology

[0002] Spinning involves processes such as impurity removal, loosening, opening, combing, combing, drafting, twisting, and winding. However, during the spinning process, impurities such as fly yarn and cotton fibers can accumulate on the rollers of the drafting device. The accumulation of these deposits can affect the normal operation of the drafting device components, so it is necessary to clean these fly yarn, cotton fibers, and other deposits frequently.

[0003] Cleaning the drafting rollers of traditional spinning machines usually requires disassembling the rollers and then having operators manually clean the deposits on the rollers with a brush.

[0004] Such operations are inefficient in terms of cleaning, and the floating debris brushed off creates an extremely harsh working environment, posing a great threat to the health of the operators. Moreover, in the confined operating space, the floating debris can also cause extreme safety hazards such as flash explosions.

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

[0006] To address the aforementioned problems in the prior art, namely the low cleaning efficiency of the drafting rollers and the impact on operator health, this utility model provides a cleaning device for the drafting rollers of a spinning machine, comprising:

[0007] A roller conveyor is used to carry and transport rollers.

[0008] A roller cleaning device is used to clean the surface of the roller and is located on the side of the roller away from the roller conveying device.

[0010] Furthermore, the roller conveying device includes a transmission belt, which is driven and connected to a drive device, and the transmission belt is used to transport the roller.

[0011] Furthermore, the transmission belt is provided with grooves or protrusions at intervals, the grooves or protrusions being used to increase the coefficient of friction between the transmission belt and the roller.

[0012] Furthermore, guide plates are symmetrically installed on the outer sides of both ends of the transmission belt along its length, and the inner side of the guide plates forms an acute angle with the running direction of the transmission belt.

[0013] Furthermore, the roller cleaning device includes a brush assembly, which is driven to rotate by a drive mechanism.

[0014] Furthermore, the dust removal device includes a dust collection hood and a dust collector;

[0015] The dust collection hood is installed outside the roller cleaning device;

[0016] The dust collector is sealed to the dust collection hood, and the dust collector is used to suck the cleaned-out flying fluff into the dust collector.

[0017] Furthermore, the dust collector includes a fluff collection device and a fan;

[0018] One end of the fluff collection device is sealed to the dust collection hood through a flow guide channel, and the other end of the fluff collection device is connected to a fan. The fan exhausts air outward to ensure that a directional airflow from the dust collection hood to the fluff collection device is formed in the flow guide channel.

[0019] Furthermore, the flow channel is provided with a turbulence generating device, which includes at least one fixed component with turbulence characteristics.

[0020] Furthermore, fixed components with turbulence-causing characteristics include guide vanes or spiral guide plates.

[0021] Furthermore, the roller is disposed in the slot and rotatably connected to the slot, the slots are arrayed and installed in the conveyor box, and the conveyor box is placed on the conveyor belt.

[0022] The beneficial effects of this utility model are:

[0023] Improved cleaning efficiency: The automated conveying of the rollers through the roller conveyor device significantly shortens the cleaning operation time and solves the problem of low efficiency in traditional manual cleaning.

[0024] Improve the working environment: The dust removal device directly adsorbs floating particles such as lint and cotton wool generated during the cleaning process, effectively preventing pollutants from spreading into the operating space and reducing the health risk of operators inhaling harmful lint.

[0036] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] The first embodiment of this utility model provides a cleaning device for the drafting roller of a spinning machine, the device comprising:

[0039] Roller conveyor 1 is used to carry and convey roller 4;

[0040] The roller cleaning device 2 is used to clean the surface of the roller 4 and is located on the side of the roller 4 away from the roller conveying device 1.

[0041] Dust removal device 3 is used to collect the flying fluff generated during the cleaning process.

[0042] In this embodiment, a U-shaped groove can be installed on the roller conveyor 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. Alternatively, a negative pressure device can be integrated on the roller conveyor 1 to firmly hold the roller 4 in place during transmission. This utility model does not limit the connection relationship between the roller 4 and the roller conveyor 1. Any method that can prevent the roller 4 from falling off the roller conveyor 1 during cleaning is within the protection scope of this utility model.

[0043] To more clearly illustrate the cleaning device for the drafting roller of a spinning machine according to this utility model, the various devices in the embodiments of this utility model are described in detail below with reference to Figures 1-8:

[0044] As shown in Figures 1, 2 and 7, the roller conveying device 1 is used to carry and convey the roller 4;

[0045] In this embodiment, the roller conveying device 1 includes a conveyor belt 11, which is drivenly connected to the driving device 12 and is used to convey the roller 4.

[0046] Referring to Figure 3, in this embodiment, the drive device 12 includes a first rotary 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 drive or a gear drive; either transmission method is within the protection scope of this utility model. This embodiment only uses a belt drive 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 rotary motor 121 is fixed on the frame 14, which is fixed to the ground. The output shaft of the first rotary motor 121 is coaxially fixed with the first pulley 1221. The first pulley 1221 is connected to the second pulley 1223 via a first conveyor belt 1222. The second pulley 1223 is coaxially fixed with the first shaft 123. The bearing of the first shaft 123 is mounted on the frame 14. The first shaft 123 is coaxially fixed with the third pulley 124. The third pulley 124 is connected to the fourth pulley 125 via a transmission belt 11. The fourth pulley 125 is coaxially fixed with the second shaft 126. The bearing of the second shaft 126 is mounted on the frame 14.

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

[0051] First stage of transmission: After the first rotary motor 121 starts, its output shaft drives the first pulley 1221, which is fixed on the same axis, to rotate.

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

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

[0054] Second stage of 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, which is coaxial with it, to rotate. The second shaft 126 is mounted on the frame 14 through bearings, which ultimately drives the transmission belt 11 to continuously circulate and complete the conveying of the roller 4.

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

[0057] In this embodiment, a U-shaped groove may be installed on the roller conveyor 1, specifically on the conveyor belt 11.

[0058] In another embodiment, the transmission belt 11 is provided with grooves or protrusions at intervals. The grooves or protrusions are used to increase the coefficient of friction 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. The groove depth or the height of the protrusion is 2-10mm, and the spacing is at least 1 / 3 of the diameter of the roller 4 to ensure that the roller 4 does not slip during the conveying process.

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

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

[0062] In another embodiment, the inner wall of the slot 5 can also be fitted with a ball bearing, so that the roller 4 can rotate freely. Using a ball bearing can reduce friction, prevent scratches on the surface of the roller 4, and extend its service life.

[0063] In this embodiment, the rotation of the roller 4 along the groove 5 enables the roller cleaning device 2 to cover a 360° area of ​​the surface, thereby improving cleaning efficiency.

[0064] The third pulley 124, the transmission belt 11, and the fourth pulley 125 can be provided on the first shaft 123 in at least one set. When a set is provided, the thickness of the third pulley 124 and the fourth pulley 125 and the width of the transmission belt 11 must be greater than or equal to the width of the conveyor box 6 to ensure the stability of the conveyor box 6 during the transmission process.

[0065] In this embodiment, two sets are used as an example. The third pulley 124, the transmission belt 11 and the fourth pulley 125 can be symmetrically arranged in two sets along the center of the first shaft 123. The conveyor box 6 is placed on the two transmission belts 11. The double sets of symmetrical transmission belts 11 can offset the force deviation on one side and improve the load-bearing capacity.

[0066] By setting up the conveyor box 6, batches of rollers 4 can be continuously processed, increasing the production capacity of the device.

[0067] Guide plates 13 are symmetrically installed on the outer sides of both ends of the conveyor belt 11 along its length. The inner side of the guide plate 13 forms an acute angle with the running direction of the conveyor belt 11. In other words, the guide plate 13 is two smooth plates symmetrically arranged at both ends of the conveyor belt 11 along the conveying direction. The two guide plates 13 form an inverted flared structure that is wider at the front and narrower at the back.

[0068] In this embodiment, the guide plate 13 is a long strip metal plate with an "L"-shaped or straight cross-section. The guide plate 13 is symmetrically installed 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 edge of the belt 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 the inclined plate guides the offset roller 4 to move towards the center of the transmission belt 11.

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

[0071] In this embodiment, a collection plate is provided at the lower part of the conveyor belt 11 to receive the falling lint. The collection plate is fixed to the frame 14. Specifically, the collection 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 lint. The edges are bent upward to form a 5-10mm retaining edge to prevent flying lint from scattering laterally.

[0072] The collecting plate is designed with a "V" or arc-shaped depression that is low in the middle and high on both sides to guide the flying fluff to gather in the middle. A dust discharge port is opened at the bottom of the depression and connected to the dust collection device.

[0073] The collection plate adopts a segmented design, with each segment being 1-1.5m in length. The segments are connected by interlocking slots or overlapping buckles to accommodate belts of different lengths.

[0074] The collecting plate has pre-drilled threaded holes at both ends, which can be used to install side baffles for further sealing.

[0075] The roller cleaning device 2 is used to clean the surface of the roller 4 and is located on the side of the roller 4 away from the roller conveying device 1.

[0076] The roller cleaning device 2 includes a brush assembly 21, which is driven to rotate by a drive mechanism 22.

[0077] In this embodiment, the roller cleaning device 2 is located on the side of the roller 4 away from the roller conveying device 1. Specifically, referring to Figure 1, the roller cleaning device 2 is located above the roller 4.

[0078] Referring to Figure 4, in this embodiment, the drive mechanism 22 includes a second rotary motor 221, a second transmission device 222, and a third shaft 223;

[0079] The second transmission device 222 is the same as the first transmission device 122, and can be configured as a belt drive or a gear drive. Either transmission method is within the protection scope of this utility model. This embodiment only uses a belt drive 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 driven by 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 connected to the frame 14 by a bearing. The brush assembly 21 is arranged along the length 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 tensioning pulley 2224 is provided between the fifth pulley 2221 and the sixth pulley 2223.

[0083] In addition, to ensure the efficiency and effectiveness of cleaning, two sets of the third shaft 223 and the sixth pulley 2223 are arranged along the transmission direction of the roller 4, and two sets of tensioning pulleys 2224 are also arranged accordingly. The two sixth pulleys 2223, the second conveyor belt 2222, the two tensioning pulleys 2224 and the fifth pulley 2221 together constitute the second transmission device 222.

[0084] The brush assembly 21 includes at least two different diameter brushes, which are spaced apart on the third shaft 223. The brushes have brush surfaces with varying heights, and the height of the brush surfaces is adapted to the surface contour of the roller 4.

[0085] The second rotary motor 221 can also be directly connected to the third shaft 223 for driving. Those skilled in the art can choose different transmission methods according to the actual arrangement of the parts. This utility model does not make any specific limitations.

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

[0087] Among them, the first brush 211 is a flexible material composed of nylon filaments and carbon fiber, which is responsible for removing large pieces of flying lint from the surface of the roller 4.

[0088] The flexible material combined with the large diameter design can efficiently remove large pieces of flying lint from the surface of the roller 4 while avoiding damage to the rubber surface of the roller 4; the wide coverage area significantly reduces surface residue.

[0089] The second brush 212 is made of a rigid material composed of stainless steel wire and nylon, which penetrates deep into the grooves of the roller 4 to clean residual fibers. The rigid metal wire penetrates deep into the complex structure of the roller 4 grooves and other areas to remove fine fibers that are difficult for traditional brushes to reach.

[0090] The use of mixed materials reduces electrostatic adsorption during the cleaning process, thus lowering the risk of secondary pollution.

[0091] The flexible combination of nylon and carbon fiber reduces surface friction and minimizes wear on the roller 4; stainless steel wires, coated with nylon, cushion contact impacts and prevent direct metal-to-roller scratches. The staggered bristle surface adapts to the contours of the roller 4, ensuring thorough cleaning.

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

[0093] In this embodiment, a keyed connection is used, which provides high torsional resistance to ensure the brush is stable during high-speed cleaning. On the other hand, it supports quick disassembly and assembly, simplifying the brush replacement process. Damaged brushes can be replaced selectively, avoiding overall scrapping and reducing consumable costs.

[0094] Dust removal device 3 is used to collect the flying fluff generated during the cleaning process.

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

[0096] The dust collection hood 31 is installed on the outside of the roller cleaning device 2 and is fixed to the frame 14;

[0097] The dust collector 32 is sealed to the dust collection hood 31, and the dust collector 32 is used to suck the cleaned-out flying fluff into the dust collector 32.

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

[0099] This utility model uses a dust collection hood 31 with an inverted funnel structure to gradually reduce the cross-section, thereby increasing the airflow speed from bottom to top, forming a high-speed airflow, enhancing the ability to carry flying catkins, and creating a low-pressure zone at the narrow outlet to strengthen the suction force on flying catkins and prevent them from escaping into the external environment.

[0100] The wide lower opening design covers the entire cleaning area of ​​the roller 4, ensuring that 100% of the lint generated during brush rotation is collected within the hood. Additionally, the sloping funnel guides the lint towards the top outlet, preventing it from accumulating disorderly inside the hood and reducing secondary dust generation.

[0101] Referring to Figure 1, the dust collector 32 includes a fluff collection device 321 and a fan 322;

[0102] One end of the fluff collection device 321 is sealed to the dust collection hood 31 through the flow guide channel 323, and the other end of the fluff collection device 321 is connected to the fan 322. The fan 322 exhausts air outward to ensure that a directional airflow from the dust collection hood 31 to the fluff collection device 321 is formed in the flow guide channel 323.

[0103] The fan 322 draws out the air inside the fluff collection device 321, creating a low pressure inside the fluff collection device 321. Utilizing the pressure difference, a fixed negative pressure is formed in the dust collection hood 31 and the guide channel 323, forming a directional airflow from the dust collection hood 31 to the fluff collection device 321. The cotton fluff brushed out by the brush assembly 21 is sent into the fluff collection device 321 for collection along with the directional airflow.

[0104] The fan 322 can be an axial flow fan or an exhaust fan; this utility model does not make any specific limitation.

[0105] The flow channel 323 can be a flexible pipe or a segmented steel pipe.

[0106] The flexible pipe is equipped with quick-install flanges at both ends, which are bolted to the dust collection hood 31 and the fluff collection device 321. The bolt preload is ≥20 N·m to ensure the airtightness of the interface. The flange surface is machined with a sealing groove and a high-temperature resistant silicone gasket is embedded.

[0107] The outlet of the flow channel 323 is machined into a 30° conical surface, which is interference-fitted with the inlet conical sleeve of the fluff collection device 321, with an interference amount of 0.1-0.2mm; the mating surface is coated with sealant, which forms a secondary seal after curing.

[0108] A dust removal door with a quick-opening handle is installed at set intervals at the bottom of the diversion pipe; it is opened during dust removal, and external airflow is drawn in by negative pressure to blow away the accumulated dust.

[0109] In this embodiment, for the long-distance flow channel 323, two fans 322 can be connected in parallel. The air volume is balanced by the air valve. If one fan fails, the other fan will automatically switch to full-load operation.

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

[0111] Among them, the fixed components with turbulence characteristics include guide vanes or spiral guide plates.

[0112] The guide vane is mounted on the inner wall of the pipe via a rotating shaft, and the tilt angle can be adjusted by an external handle.

[0113] In high-humidity environments where fluff tends to clump together, the tilt angle is increased to 45° to enhance the breaking effect; in dry environments, it is adjusted to 15° to reduce energy consumption.

[0114] The spiral guide plate is spirally wound around the inner wall of the pipe. Each spiral plate section is 500mm long and is connected by flange bolts to adapt to pipes of different lengths. The spiral directions of adjacent sections are opposite, one section spirals to the left and the other to the right, which enhances the turbulence effect.

[0115] Referring to Figure 5, in this embodiment, the lower front edge of the dust collection hood 31 is provided with a plurality of wedge-shaped guide blocks 311. 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 this utility model guides the roller 4 to automatically center itself 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 brush tip can be fully embedded in the groove on the surface of the roller 4, avoiding cleaning blind spots caused by positional deviation.

[0117] In this embodiment, the position of the guide block 311 can be finely adjusted to adapt to different groove spacings of the roller 4 model, thereby improving the cleaning coverage.

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

[0119] The second embodiment of this utility model proposes another cleaning device for the drafting roller of a spinning machine. Based on the first embodiment, a spraying device is added. Specifically:

[0120] Given the application characteristics of this utility model, the cotton lint and fluff removed are lightweight and will float around everywhere. On the one hand, this will cause poor air quality in the operating environment and seriously affect the health of on-site operators. On the other hand, these floating fibrous materials are highly flammable and explosive, posing a serious safety hazard.

[0121] The cleaning device for the drafting roller of the spinning machine of this utility model can also target the drying and moisture absorption characteristics of the flying cotton fibers. By adding a spray device inside the dust collection hood 31, the humidity of the cleaning environment and the presence of a moderate amount of mist are maintained. By utilizing the moisture absorption characteristics of the flying cotton fibers, the specific gravity of the flying cotton fibers increases after absorbing moisture, making it difficult for them to float.

[0122] Based on the principle of utilizing the moisture absorption and weight gain of cotton fibers, the directional airflow formed by the dust collection hood 31 and the directional fan 322 is used to send these cotton fibers to the dust collector for collection and treatment.

[0123] The spraying device includes a mist nozzle and a mist generator housed within a dust cover.

[0124] The fog generator can be either an ultrasonic fog generator or an electrically heated fog generator.

[0125] The third embodiment of this utility model proposes another cleaning device for the drafting roller of a spinning machine. Based on the first embodiment, a set of air inlets are provided on the side shell of the dust collection hood 31. The axial direction of the air inlets has the same angle as the vertical central axis of the dust collection hood 31. The airflow from each air inlet enters the dust collection hood 31 at a certain angle with the vertical central axis of the dust collection hood 31. They can work together to form a rotating airflow with the vertical central axis of the dust collection hood as the central axis. Combined with the directional fan 322, they jointly form a directional rotating airflow in the dust removal environment, which can further improve the dust removal effect of the airflow.
