Description

Technical Field

[0001] This utility model relates to the field of rubber roller technology, specifically to a cleaning structure for the rubber rollers of a fine yarn drawing frame. Background Technology

[0002] The drawing process is an important step in yarn production. On the drawing frame, cotton slivers are drawn together and drafted to improve fiber parallelism and reduce weight unevenness. As an important drafting component of the drawing frame, the quality and smoothness of the rollers directly affect the product quality. For spinning fine yarns, the spinning process is required to be more stringent and the yarn quality to be higher.

[0003] In the prior art, Chinese utility model publication CN217324452U discloses a spinning drawing roller, specifically relating to the field of rollers. It includes a roller core and a roller body fitted onto the outer surface of the roller core. One side of the roller body has a connecting groove, and the roller core is located inside the connecting groove. Three sets of anti-slip components are evenly distributed on the outer surface of the roller body. Each set of anti-slip components includes protrusions evenly distributed on the circumference of the roller body, and the outer surface of the protrusions is bonded with an anti-slip layer. This utility model, by setting anti-slip components on the outer surface of the roller body, avoids the traditional method of anti-slip through grooving, increasing service life. When the device is in normal use, the roller body rolls normally, and the yarn fits onto the outer surface of the roller body, closely adhering to the outer surface of the protrusions. The anti-slip layer on the outer surface of the protrusions increases the traction force on the yarn during rotation.

[0004] However, existing guide rollers have defects in use. They are prone to causing yarn defects when spinning fine yarns. Yarn defects not only affect the production efficiency of subsequent winding processes, but also affect the fabric quality, increase the workload of fabric repair workers, and affect the overall style and other intrinsic quality of the fabric. Cotton lint is easily wrapped around the drawing rollers. Cotton wax impurities and cotton lint accumulate and increase on the guide rollers, eventually entering the drafting zone with the sliver. This causes unevenness and high impurity levels in the sliver, affecting the quality of subsequent yarn. Because cotton short fibers accumulate and wrap around the guide rollers, cleaning the guide rollers is also very inconvenient. Therefore, we need to propose a drawing roller cleaning structure for fine yarn drawing frames. Utility Model Content

[0005] The purpose of this invention is to provide a cleaning structure for the drawing roller of a fine yarn drawing frame, which facilitates the scraping of impurities such as short fibers and cotton wax on the drawing roller, thereby ensuring the cleanliness of the drawing roller surface, improving the quality of fine yarn spinning, and facilitating the collection and treatment of the cleaned impurities, thus improving cleaning efficiency and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cleaning structure for the drawing roller of a fine yarn drawing frame, comprising a housing, a roller body and a cleaning roller rotatably connected within the housing cavity, the outer surface of the cleaning roller abutting against the outer surface of the roller body, a lifting mechanism provided at the bottom of the housing cavity, a driving component mounted on the lifting mechanism, a support plate displaced by the driving component mounted on the lifting mechanism, a first scraping mechanism for cleaning the roller body mounted on the upper surface of the support plate, and a second scraping mechanism for cleaning the surface of the cleaning roller mounted on one side of the support plate, the first scraping mechanism being slidably connected above the second scraping mechanism.

[0007] Preferably, the first scraping mechanism includes a connecting plate, and a retaining frame that is slidably connected to both sides of the support plate is fixedly connected to the lower surface of the connecting plate. Multiple sets of first telescopic spring sleeves are fixedly connected to the top of the inner cavity of the retaining frame, and the lower ends of the multiple sets of first telescopic spring sleeves are fixedly connected to the upper surface of the support plate.

[0008] Preferably, a conical plate that abuts against the rubber roller body is fixedly connected to one side of the connecting plate, and an arc-shaped groove that fits the rubber roller body is opened on one side of the conical plate, and an upper baffle is fixedly connected to one side of the card frame.

[0009] Preferably, the second scraping mechanism includes a mounting plate and a scraper. A plurality of limiting rods penetrating the support plate are fixedly connected to one side of the mounting plate, and buffer springs are sleeved on the outer side of each of the plurality of limiting rods. A plurality of screws penetrating the mounting plate are fixedly connected to one side of the scraper, and a locking nut is threaded to one end of each of the screws.

[0010] Preferably, the other side of the scraper is provided with an inner groove for the cleaning roller to fit against, and multiple sets of scraping blocks are provided on the inner groove wall. The multiple sets of scraping blocks are arranged in a rectangular array. A lower baffle is fixedly connected to the upper end of one side of the mounting plate. Multiple sets of second telescopic spring sleeves are fixedly connected to one side of the lower baffle. One end of each set of second telescopic spring sleeves is fixedly connected to one side of the frame. The lower surface of the upper baffle is slidably connected to the upper surface of the lower baffle.

[0011] Preferably, the lifting mechanism includes two sets of cylinders installed at the bottom of the inner cavity of the housing. The telescopic ends of the two sets of cylinders are fixedly connected to a mounting box. The inner cavity of the mounting box is fixedly connected to two sets of guide rods for sliding connection of the support plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model mainly utilizes the cooperation between the support plate, the first scraping mechanism, and the second scraping mechanism. The conical plate of the first scraping mechanism facilitates the scraping of cotton wax impurities from the surface of the rubber roller body, preventing excessive impurities from affecting the production quality of the yarn. At the same time, the cleaning roller scrapes away short fibers from the surface of the rubber roller body, preventing excessive accumulation of short fibers from affecting the cleanliness of the yarn. Through this dual cleaning method, the yarn quality after the production of fine yarn is improved, and the scraped impurities and short fibers are easy to clean and collect, thus improving the cleaning efficiency of the surface of the rubber roller body.

[0015] 2. This utility model utilizes the cooperation between the lifting mechanism and the transmission gear. The lifting mechanism facilitates the adjustment of the height of the first scraping mechanism, and the driving component adjusts the position of the second scraping mechanism, thereby enabling both to fit against the rubber roller body and the cleaning roller respectively, facilitating the cleaning of impurities and providing convenient operation. The transmission gear makes the rotation directions of the rubber roller body and the cleaning roller opposite, thereby improving the cleaning effect on short fibers. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a cleaning structure for the drawing roller of a fine yarn drawing frame, including a housing 1, a roller body 2 and a cleaning roller 6 rotatably connected inside the housing 1, the outer surface of the cleaning roller 6 abutting the outer surface of the roller body 2, a lifting mechanism 8 provided at the bottom of the inner cavity of the housing 1, a driving component 9 installed on the lifting mechanism 8, a support plate 10 installed on the lifting mechanism 8 and displaced by the driving component 9, a first scraping mechanism 11 for cleaning the roller body 2 installed on the upper surface of the support plate 10, a second scraping mechanism 12 for cleaning the surface of the cleaning roller 6 installed on one side of the support plate 10, and the first scraping mechanism 11 slidably connected above the second scraping mechanism 12.

[0024] The first scraping mechanism 11 includes a connecting plate 111. A retaining frame 113 is fixedly connected to the lower surface of the connecting plate 111 and slidably connected to both sides of the support plate 10. Multiple sets of first telescopic spring sleeves 114 are fixedly connected to the top of the inner cavity of the retaining frame 113. The lower ends of the multiple sets of first telescopic spring sleeves 114 are all fixedly connected to the upper surface of the support plate 10. The retaining frame 113 facilitates the protection of the first telescopic spring sleeves 114, preventing the scraped cotton wax from adhering to the first telescopic spring sleeves 114 and affecting the elasticity of the spring. The first telescopic spring sleeve 114 is mainly composed of a telescopic sleeve and a spring. Similarly, the second telescopic spring sleeve 123 has the same composition as the first telescopic spring sleeve 114.

[0025] A conical plate 112 that abuts against the rubber roller body 2 is fixedly connected to one side of the connecting plate 111. An arc-shaped groove that fits the rubber roller body 2 is opened on one side of the conical plate 112. An upper baffle 115 is fixedly connected to one side of the frame 113. Both ends of the conical plate 112 are conical, which makes it easy to scrape off the cotton wax on the surface of the rubber roller body 2, thereby improving the cleanliness of the surface of the rubber roller body 2 and improving the quality of the yarn drawing.

[0026] The second scraping mechanism 12 includes a mounting plate 121 and a scraper 126. A plurality of limiting rods 124 penetrating the support plate 10 are fixedly connected to one side of the mounting plate 121. A buffer spring 125 is sleeved on the outer side of each of the limiting rods 124. A plurality of screws 128 penetrating the mounting plate 121 are fixedly connected to one side of the scraper 126. A locking nut 129 is threaded to one end of each screw 128. The locking nut 129 facilitates the installation of the scraper 126. At the same time, the buffer spring 125 prevents the scraper 126 from rigidly contacting the cleaning roller 6, thereby improving the service life of the scraper 126.

[0027] The other side of the scraper 126 has an inner groove for the cleaning roller 6 to fit against, and multiple sets of scraper blocks 127 are arranged on the inner groove wall in a rectangular array. A lower baffle 122 is fixedly connected to the upper end of one side of the mounting plate 121. Multiple sets of second telescopic spring sleeves 123 are fixedly connected to one side of the lower baffle 122. One end of each set of second telescopic spring sleeves 123 is fixedly connected to one side of the frame 113. The lower surface of the upper baffle 115 is slidably connected to the upper surface of the lower baffle 122. The lower baffle 122 and the upper baffle 115 overlap alternately to prevent the cotton scraped off by the cone plate 112 from falling on the second telescopic spring sleeves 123 and the buffer spring 125, affecting the elasticity, thereby improving the service life of the second scraping mechanism 12.

[0028] The lifting mechanism 8 includes two sets of cylinders 81 installed at the bottom of the inner cavity of the housing 1. The extension and retraction ends of the two sets of cylinders 81 are fixedly connected to the mounting box 82. The inner cavity of the mounting box 82 is fixedly connected to two sets of guide rods 83 for sliding connection of the support plate 10. The driving component 9 is installed in the inner cavity of the mounting box 82. The cylinders 81 facilitate the adjustment of the position of the first scraping mechanism 11 and the second scraping mechanism 12, so that the two slowly contact the rubber roller body 2 and the cleaning roller 6, thereby improving the cleaning efficiency of cotton wax and short fibers on the outer surface of the rubber roller body 2.

[0029] One end of the cleaning roller 6 passes through the housing 1 and is driven by the rotary motor 5. The other end of the cleaning roller 6 passes through the housing 1 and is fixedly connected to the drive gear 7. One end of the rubber roller body 2 passes through the housing 1 and is fixedly connected to the driven gear 3. A transmission gear 4 that meshes with the drive gear 7 and the driven gear 3 is rotatably connected to one side of the housing 1. The cleaning roller 6 is driven to rotate by the rotary motor 5, and then the rubber roller body 2 and the cleaning roller 6 rotate relative to each other under the action of the transmission gear 4. This reduces the driving equipment and lowers the equipment cost, while also facilitating the cleaning roller 6 to clean the short fibers on the surface of the rubber roller body 2.

[0030] In use, the rotary motor 5 drives the cleaning roller 6, which in turn drives the drive gear 7 to mesh with the transmission gear 4. The transmission gear 4 meshes with the driven gear 3, causing the rubber roller body 2 and the cleaning roller 6 to rotate relative to each other. This is achieved by the cylinder 81 driving the mounting box 82 to rise, which in turn drives the support plate 10 to move horizontally via the drive component 9. This causes the cone plate 112 to lightly touch the outer surface of the rubber roller body 2, while the scraper block 127 of the scraper 126 comes into contact with the surface of the cleaning roller 6. When the cone plate 112 comes into contact, the first telescopic spring sleeve 114 cushions the contact, thus ensuring that the cone plate 112 fits tightly against the rubber roller body. Similarly, the scraper 126 is buffered by the buffer spring 125 on the surface of the body 2, so as to avoid the scraper 126 rigidly contacting the cleaning roller 6 and damaging the surface of the cleaning roller 6. This improves the efficiency of the scraper block 127 in cleaning the cotton on the surface of the cleaning roller 6. The cleaning roller 6 cleans the short fibers on the surface of the rubber roller, and the scraper block 127 cleans the short fibers on and off the cleaning roller 6. The surface of the rubber roller body 2 is cleaned in multiple ways, thereby improving the cleaning efficiency of the surface of the rubber roller body 2. At the same time, it is convenient to clean the impurities that are cleaned off, reducing the labor intensity of the workers.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
