Description

Technical Field

[0001] This utility model relates to the field of textile roller auxiliary device technology, and in particular to a textile roller cleaning device. Background Technology

[0002] In the drafting process of cotton yarn spinning, the roller is a key component. Its main function is to hold and pull the fiber sliver by rotating a combination of several pairs of grooved metal rollers at a specific speed. The speed difference between the front and rear rollers gradually thins and straightens the fiber bundle, eventually forming a uniform yarn. The stability of this process directly determines the quality of the yarn. However, because the roller rotates at high speed and is in direct contact with the cotton yarn, it is very easy to accumulate a mixture of short fibers, cotton wax, oil dust, etc. These accumulations can lead to problems such as increased yarn defects, uneven yarn, and yarn wrapping. Therefore, the roller needs to be cleaned regularly.

[0003] The conventional methods currently used for cleaning rollers mainly include the following two types: First, a fixed metal or plastic scraper structure is installed, which is used to mechanically scrape against the roller to remove surface polymers. However, this method is prone to uneven contact pressure with the roller surface due to installation deviation or long-term wear. This not only makes it difficult to completely remove the mixture of oil, wax and short fibers in the grooves, but also poses a risk of scratching the coating of the precision roller. Second, an intermittent blowing and suction device with external power is used to blow away fly shavings with compressed air and then suck them away with negative pressure. The high-speed airflow can easily cause lightweight fibers to diffuse into the air, causing secondary pollution of the workshop environment and increasing the burden of equipment cleaning. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a textile roller cleaning device that solves the problems of incomplete cleaning by fixed scrapers, easy damage to rollers, and easy diffusion and pollution of fly waste caused by high-speed airflow.

[0005] According to an embodiment of the present invention, a textile roller cleaning device includes a rotatable cleaning roller with a plurality of bristles evenly distributed on its surface. A drive source for rotating the cleaning roller is fixedly disposed on one side of the cleaning roller. A cleaning chamber is fixedly disposed at the bottom of the cleaning roller, and a dust extraction fan is connected to the cleaning chamber. A cleaning mechanism is also fixedly disposed in the cleaning chamber. The cleaning mechanism includes a scraper and an air jet pipe. The outer end of the scraper is close to the cleaning roller and abuts against the bristles. The air inlet end of the air jet pipe is connected to an air intake fan, and the air outlet end is connected to a nozzle facing the cleaning roller.

[0006] The technical principle of this invention is as follows: The cleaning roller is driven to rotate by a drive source. The densely covered bristles on its surface keep in contact with the surface of the textile roller and move in the opposite direction. The bristles can completely cover the roller surface and provide a uniform scouring force. By penetrating deep into the roller grooves, the bristles thoroughly peel off and remove the attached short fibers, wax, and other accumulated substances, ensuring a cleaning effect. During the cleaning process, the scraper continuously scrapes off the impurities adhering to the bristles to ensure the surface of the bristles is clean. At the same time, the air jet pipe sprays airflow onto the bristles to further blow off residual dirt. The removed impurities are quickly sucked into the cleaning chamber by the vacuum fan, achieving sealed collection and preventing pollution from spreading.

[0007] Furthermore, the cleaning roller is rotatably disposed within the housing, the housing surrounds and encloses the bottom of the cleaning roller, a gap is left between the housing and the bristles, and the cleaning chamber is connected to the bottom of the housing.

[0008] Furthermore, the housing has a collection section extending and fixed at the bottom of the working surface side of the cleaning roller, and the diameter of the collection section is larger than the diameter of the housing.

[0009] Furthermore, the vacuum cleaner is fixedly connected to the side wall of the housing, a dust filter plate is fixedly installed at the connection between the vacuum cleaner and the cleaning chamber, and an air outlet is fixedly installed on one side of the vacuum cleaner.

[0010] Furthermore, the air intake fan is fixedly connected to the side wall of the housing, and an air inlet is provided at the bottom of the air intake fan.

[0011] Furthermore, the nozzle is configured with a reduced diameter structure, and several nozzles are evenly connected and arranged on the air jet pipe, with the gas ejected from the nozzles covering the surface of the cleaning roller.

[0012] Furthermore, the cleaning device also includes a mounting base, on which a sliding guide rail is fixedly mounted, and a sliding block that can engage with and slide relative to the sliding guide rail is fixedly mounted on the back of the housing.

[0013] Furthermore, a pair of mounting blocks are fixedly installed at both ends of the sliding guide rail, and a lead screw is rotatably installed between the two mounting blocks. A servo motor that can drive the lead screw to rotate is fixedly installed on the outside of one mounting block, and an internal thread that can mesh with the lead screw is provided on the sliding block.

[0014] Furthermore, the scraper is hinged to the inner wall of the cleaning chamber, and a locking element that can lock the scraper is fixedly provided at the hinge point between the scraper and the cleaning chamber.

[0015] Furthermore, the drive source includes a geared motor, the output end of which is coaxially and fixedly connected to the cleaning roller.

[0016] Compared with existing technologies, this invention has the following advantages: the densely packed bristles on the surface of the cleaning roller and the fitting structure of the roller grooves achieve deep removal of accumulated materials. At the same time, the contact between the scraper and the bristles and the directional blowing of the air jet pipe complete the real-time self-cleaning of the bristles. The sealed design of the cleaning chamber, combined with the negative pressure suction of the vacuum fan, ensures that impurities are efficiently collected without diffusion. The above structure ensures the thoroughness of roller cleaning and realizes continuous automation and low pollution emissions in the cleaning process. Attached Figure Description

[0025] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0026] like Figure 1-4As shown in the figure, this utility model embodiment proposes a textile roller cleaning device, which includes a horizontally rotating cleaning roller 1. A plurality of bristles 11 are evenly distributed on the surface of the cleaning roller 1. The bristles 11 directly contact the textile roller when the cleaning roller 1 rotates, and remove impurities from the roller surface and grooves through rapid rotation. A drive source is fixedly installed on one side of the cleaning roller 1 to drive its rotation. A cleaning chamber 21 is fixedly installed at the bottom of the cleaning roller 1. A vacuum fan 3 is connected inside the cleaning chamber 21, which can adsorb and collect impurities. The cleaning mechanism is also fixedly installed inside. The cleaning mechanism includes a scraper 4 and an air jet pipe 51. The outer end of the scraper 4 is close to the cleaning roller 1 and abuts against the bristles 11. When the bristles 11 rotate and pass over the scraper 4, they will contact the scraper 4 from the root upwards in sequence. The scraper 4 will scrape off the impurities on the bristles 11 and keep the bristles 11 clean. The air inlet end of the air jet pipe 51 is connected to an air intake fan 5, and the air outlet end is connected to a nozzle 52. The nozzle 52 faces the cleaning roller 1. The high-speed gas sprayed by the nozzle 52 can blow off the impurities on the bristles 11, realizing the self-cleaning of the bristles 11.

[0027] In this exemplary embodiment, the bristles 11 are made of high-elasticity nylon, polypropylene, pig bristles, horsehair, or other rigid elastic materials. Driven by a driving source, they rotate in the opposite direction to the roller. Utilizing the flexible deformation characteristics of the bristles 11, they penetrate deep into the grooves of the roller, thoroughly peeling off and removing short fibers, wax, and other impurities adhering to the roller surface through mechanical brushing. The size, shape, and arrangement of the bristles 11 are set according to actual conditions to ensure that the ends of the bristles 11 uniformly cover and contact the roller surface, and are not limited here. The length of the scraper 4 is preferably set to be the same as or slightly longer than the length of the cleaning roller 1 to ensure that it can cover the entire roller surface. The width of the scraper 4 is set according to actual conditions, and the distance between its outer end and the roller surface of the cleaning roller 1 determines the initial contact position between the scraper 4 and the bristles 11, realizing the peeling of impurities from the root to the tip of the bristles 11. The cleaning chamber 21 is connected to the vacuum fan 3, which uses negative pressure to quickly suck in and seal the scraped and blown impurities, effectively preventing them from scattering. Based on the above structural design, the flexible bristles 11 ensure cleaning effectiveness while avoiding damage to the roller coating. The combination of the scraper 4 and the nozzle 52 enables real-time self-cleaning of the bristles 11, ensuring the continuous and efficient operation of the cleaning roller 1. The closed negative pressure collection structure fundamentally eliminates secondary pollution, significantly improving the cleaning efficiency and practicality of the device.

[0028] The technical principle of this utility model is as follows: The cleaning roller 1 is driven to rotate by a drive source. The bristles 11 densely distributed on its surface maintain contact with the surface of the textile roller and move in the opposite direction. The bristles 11 can completely cover the roller surface and provide uniform scouring force. By penetrating into the grooves of the roller, the bristles 11 thoroughly peel off and remove the attached short fibers, oil wax and other accumulated substances, ensuring the cleaning effect. This device can flexibly choose manual hand-held or mechanical fixed cleaning methods according to specific circumstances. During the cleaning process, the scraper 4 continuously scrapes off the impurities adhering to the bristles 11 to ensure the surface of the bristles 11 is clean. At the same time, the air jet pipe 51 supplies air through the air intake fan 5 and sprays it onto the bristles 11 through the nozzle 52. Airflow further blows away residual dirt, and the removed impurities are quickly sucked into the cleaning chamber 21 by the vacuum fan 3, achieving sealed collection and preventing pollution from spreading. This utility model achieves in-depth removal of accumulated materials through the fit between the densely distributed bristles 11 on the surface of the cleaning roller 1 and the roller grooves. At the same time, the contact between the scraper 4 and the bristles 11 and the directional blowing of the air jet pipe 51 complete the real-time self-cleaning of the bristles 11. The sealed design of the cleaning chamber 21, combined with the negative pressure suction of the vacuum fan 3, ensures that impurities are collected efficiently without diffusion. The above structure ensures the thoroughness of roller cleaning and realizes continuous automation and low pollution emissions in the cleaning process.

[0029] like Figure 1-4 As shown, in another embodiment, the cleaning roller 1 is rotatably disposed within the housing 2. The housing 2 is preferably made of lightweight metal or engineering plastic. The inner wall contour of the housing 2 is adapted to the outer edge of the cleaning roller 1 and surrounds it from the bottom to the back one-third of its circumferential range. A reasonable operating gap is maintained between the housing 2 and the tip of the bristles 11 to avoid interference with rotation and to prevent large impurities from splashing out. The cleaning chamber 21 is connected to the bottom of the housing 2 to form a sealed collection channel. Based on the above structural configuration, the housing 2 provides a stable mounting base and physical protection for the cleaning roller 1, effectively blocking external interference and mechanical collisions. At the same time, its surrounding structure effectively constrains the impurities swept off during the cleaning process in the cavity between the inner wall of the housing 2 and the cleaning roller 1. Through the bottom connection port, the impurities are guided in an orderly manner to the cleaning chamber 21 for centralized processing using negative pressure, which significantly improves the directionality and efficiency of impurity collection, avoids the scattering of flying debris, and makes the entire cleaning and collection process more concentrated and efficient.

[0030] like Figure 1-4As shown, in another embodiment, the housing 2 further extends outward from the bottom of the working surface of the cleaning roller 1 in contact with the roller, and a collection part 22 is fixed thereon. The collection part 22 adopts an arc-shaped plate structure integrally formed with the housing 2, and its diameter is significantly larger than the main diameter of the housing 2. The expanded diameter range fully covers the area below the contact line between the cleaning roller 1 and the roller, forming a pocket-shaped collection mechanism. Based on the above structural setting, the expanded diameter collection part 22 forms a guiding material collection space with a large material receiving area at the bottom of the working position of the cleaning roller 1. It can effectively receive impurities swept down from the cleaning area of ​​the roller and the cleaning roller 1 and thrown off by centrifugal force. Its pocket opening structure guides the impurities to slide into the connecting area of ​​the cleaning chamber 21, avoiding the accumulation or rebound splashing of impurities at the edge of the housing 2, and significantly improving the capture rate and guiding effect of impurity collection.

[0031] like Figure 1-5 As shown, in another embodiment, the vacuum cleaner 3 is further fixedly connected to the outer side wall of the housing 2 via a mounting bracket. An air outlet 31 is fixedly provided on one side, and its air inlet communicates with the interior of the cleaning chamber 21. A dust filter plate 32 is fixedly provided at the communication point between the two. The dust filter plate 32 includes a woven mesh, a perforated plate, or a grid, and its material includes metal or polymer. The pore size for dust filtration is preferably between 0.5-1.0 mm, which can be adjusted according to the actual cleaning conditions. Based on the above structural configuration, the dust filter plate 32 forms a filtration barrier in the airflow channel, which can effectively intercept the sucked-in fiber clumps, oil wax blocks, and other solid impurities, preventing impurities from entering the vacuum cleaner 3 and avoiding exhaust interference with the cleaning area or causing secondary dust.

[0032] like Figure 1-2 As shown, in another embodiment, the air intake fan 5 is further fixedly installed at the lower part of the side wall of the housing 2, and its air outlet is reliably connected to the jet pipe 51 inside the housing 2 through a sealing joint. The bottom of the air intake fan 5 is provided with a large air inlet 53, which is directly connected to the jet pipe 51 through a short and straight passage. Based on the above structural configuration, the air intake fan 5 ensures that the airflow to the jet pipe 51 has sufficient pressure and flow, providing a stable and reliable power source for the efficient air blowing cleaning of the bristles 11.

[0033] like Figure 1-4As shown, in another embodiment, the nozzle 52 is further configured as a tapered, tapered structure with a gradually narrowing front end. Several nozzles 52 are uniformly arranged and fixed along the length of the jet pipe 51 by threaded connection or integral forming. The outlet direction of the nozzle 52 is precisely aligned with the bristle 11 area of ​​the cleaning roller 1, ensuring that the gas ejected by the nozzle 52 covers the roller surface of the cleaning roller 1. Based on the above structural configuration, the tapered structure accelerates the airflow to form a high-speed, concentrated air jet through the Venturi effect, significantly enhancing the penetration and impact of the airflow. It can effectively penetrate the bristle 11 layer and blow off the deep impurities remaining after the scraper 4 has removed them. The uniform arrangement of the nozzles 52 ensures that the jet airflow forms a continuous, dead-zone-free coverage within the axial range of the cleaning roller 1, so that the bristles 11 of the entire roller surface can be uniformly and thoroughly cleaned by air blowing, avoiding local impurity residue. This ensures the continuous and stable working performance and self-cleaning effect of the cleaning roller 1, resulting in high overall airflow utilization efficiency and significantly improved cleaning effect.

[0034] like Figure 1-2 and Figure 6-7 As shown, in another embodiment, the cleaning device further includes a rigid mounting base 6, which is bolted to the textile equipment frame and located on one side of the roller shaft end. A linear sliding guide rail 61 with a T-shaped or dovetail-shaped cross-section is fixedly mounted on the mounting base 6. A sliding block 23, capable of engaging and sliding relative to the sliding guide rail 61, is fixedly mounted on the back of the housing 2. Specifically, the sliding block 23 has a sliding groove 231 in the middle that matches the shape of the sliding guide rail 61. The housing 2 slides smoothly along the axial direction of the sliding guide rail 61 through the groove-rail engagement. Based on the above structural configuration, the operator can... The entire cleaning unit (including cleaning roller 1 and housing 2) can be flexibly and smoothly pushed along the sliding guide rail 61 on the mounting base 6 as needed, so that the entire cleaning device can move along the roller axis. This allows for flexible adjustment of the contact position between the cleaning roller 1 and different sections of the roller (such as sections where impurities easily accumulate or positions that need to be avoided), enabling targeted cleaning or avoidance of the entire length of the long roller. This greatly expands the applicability and flexibility of the device. At the same time, the sliding structure also facilitates the removal of the entire cleaning unit from the working position, providing convenient operating space for roller maintenance, equipment cleaning, or replacement of the bristles 11.

[0035] like Figure 1-2 and Figure 6-7As shown, in another embodiment, a pair of mounting blocks 621 are further fixedly provided at both ends of the sliding guide rail 61. A lead screw 62 is precisely coaxially rotatably provided between the two mounting blocks 621. A servo motor 622 is fixedly provided on the outer side of one mounting block 621 and directly connected to the end of the lead screw 62 via a coupling. The sliding block 23 is provided with an internal thread 232 that precisely matches the lead screw 62. The rotational motion of the motor is converted into linear displacement of the sliding block 23 by thread engagement with the rotating lead screw 62. Based on the above structural configuration, the servo motor 622 can drive the lead screw 62 to perform precise forward and reverse rotation according to the received control signal. Through the thread engagement, the sliding block 23 and the entire cleaning device are moved axially along the sliding guide rail 61, realizing precise control of the contact part between the cleaning roller 1 and the roller. This not only realizes the automation and remote control of the cleaning process, but also precisely controls the residence time and moving speed of the cleaning roller 1 in the roller axis, ensuring a uniform cleaning effect throughout the entire length of the long roller and avoiding the uncertainty of manual operation.

[0036] like Figure 1-4 As shown, in another embodiment, the scraper 4 is connected to the inner wall of the cleaning chamber 21 via a hinge 41 mechanism, allowing it to rotate around the hinge point to adjust its relative angle with the cleaning roller 1. A locking element is fixedly provided at the hinge point between the scraper 4 and the cleaning chamber 21 to lock the scraper 4. In this embodiment, the locking element includes a knob 42 coaxially arranged with the hinge shaft and a screw fixedly connected to the knob 42. A threaded hole is coaxially provided on one side of the hinge shaft, and the screw engages with the threaded hole. By tightening the knob 42, the end of the knob 42 can be pressed against the side wall of the hinge seat. Now locked; based on the above structural settings, the operator can change the contact width and cutting angle between the working surface of the scraper 4 and the bristles 11 of the cleaning roller 1 by rotating the scraper 4, thereby adapting to different cleaning needs of the bristles 11 or the requirements for peeling off different sticky impurities; after adjustment, tightening the knob 42 will reliably lock the scraper 4 at the current angle through the axial pressure generated by the knob 42, ensuring the stability of the cleaning operation process, realizing the flexible adjustment and quick locking of the working state of the scraper 4, and significantly improving the adaptability of the cleaning mechanism to different working conditions and the convenience of maintenance.

[0037] like Figure 1-4 As shown, in another embodiment, the drive source includes a geared motor 12, the output end of which is coaxially and fixedly connected to the cleaning roller 1. Based on the above structural configuration, the geared motor 12 converts the high-speed, low-torque power source into the optimal low-speed, high-torque rotational motion required by the cleaning roller 1, ensuring the extreme stability and precise controllability of the rotational speed of the cleaning roller 1.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
