Description

Technical Field

[0001] This utility model relates to the field of spinning technology, specifically to a roving frame cleaning structure for cotton yarn production. Background Technology

[0002] The spinning frame is a key piece of equipment in the spinning process. Its main principle is to draft, twist, and wind the drawn sliver into roving, providing suitable yarn bundles for the subsequent spinning process. The drafting mechanism draws the fiber sliver to a specified thickness, and then the spindle mechanism performs appropriate twisting to give it initial strength. Finally, the twisted roving is wound orderly onto the bobbin through lifting and lowering motion, ensuring the uniformity, strength, and shape of the roving to meet the feeding requirements of the spinning frame. Short fibers exist on the roving frame, which easily accumulate in the drafting zone, interfering with the normal drafting of the main fiber bundle, resulting in uneven yarn and forming thick and thin yarn defects. Excessive short fibers can also be twisted into the yarn body, increasing the surface hairiness of the final yarn, reducing its smoothness, and impairing its strength, seriously weakening the quality of the final product.

[0003] Regarding the technical problems existing in the roving frame cleaning structure for cotton yarn production mentioned above, a search revealed a patent (CN202222425407.1) for a roving frame cleaning structure for cotton yarn production. Its technical solution includes: a housing, a pressurizing component, a dust-collecting component, and a bottom shell. The pressurizing component is fixedly installed inside the housing, and an airbag is installed inside the pressurizing component. An exhaust valve is fixedly installed at equal intervals on one side of the airbag, and an adjusting plate is fixedly installed on one side of the exhaust valve. The dust-collecting component is welded to the bottom of the housing, and a dust-collecting box is installed inside the dust-collecting component. A dust extraction port is opened on one side of the top of the dust-collecting box. This utility model, through the combination of various structures, allows the device to install an airbag inside the housing, which can store air and generate high-pressure air. By releasing the high-pressure air, it impacts the lint adhering inside the roving frame, causing the lint to fall off the surface of the roving frame and float in the air. This facilitates the suction of hard-to-clean lint, greatly improving the cleaning effect of the roving frame.

[0004] In actual use, the roving frame cleaning structure used in cotton yarn production only cleans the lint inside the roving frame through a dust collection component. The airborne short fibers are easily blown onto and adhere to the surface of the roving being wound. These short fibers are then entangled and embedded in the spinning roving itself, resulting in obvious thick and thin spots in the roving, severely damaging the evenness of the yarn and affecting the quality of the subsequent fine yarn. At the same time, because the short fibers collected in the dust collection box are extremely light, even a slight disturbance or the airflow generated by opening the box door during subsequent cleaning operations is enough to cause these collected short fibers to fly and disperse again. The re-blown short fibers cannot be effectively controlled and easily escape from the box, spreading back into the workshop air and causing repeated pollution. Utility Model Content

[0005] The purpose of this utility model is to provide a roving cleaning structure for cotton yarn production.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a roving frame cleaning structure for cotton yarn production, comprising a first back plate, a first mounting plate fixedly connected to the top of the first back plate, a wire loop fixedly connected to the outer surface of the first mounting plate, a second back plate fixedly connected to the bottom of the first back plate, a first motor and a second motor fixedly mounted on the top of the first mounting plate, a rotating shaft fixedly connected to the output end of the first motor, a cleaning roller fixedly connected to the outer surface of the rotating shaft, a rotating head fixedly connected above the outer surface of the rotating shaft, a drive chain movably connected to the outer surface of the rotating head, a lead screw fixedly connected to the output end of the second motor, a scraper movably connected to the outer surface of the lead screw, a cleaning box fixedly connected to the top of the second back plate, a dust inlet pipe fixedly connected to the outer surface of the cleaning box, and a second mounting plate movably connected to the back of the cleaning box. An air extractor is fixedly mounted on the back of the second mounting plate, a mesh plate is fixedly connected inside the second mounting plate, a support rod is fixedly connected to the outer surface of the mesh plate, and scraper strips are fixedly connected to both sides of the support rod.

[0007] As a further embodiment of this utility model: the interior of the rotating head is recessed inward, and a toothed block is provided inside the rotating head. The rotating head is connected to the drive chain through the toothed block.

[0008] As a further embodiment of this utility model: the drive chain is cross-wound around the toothed block of the rotating head, and there are two rotating heads, which rotate in opposite directions.

[0009] As a further embodiment of this utility model: the lead screw is located on the outer side of the cleaning roller, the scraper is moved from top to bottom on the outer surface of the lead screw, the scraper abuts against the outer side of the cleaning roller, and the scraper is made of silicone material.

[0010] As a further embodiment of this utility model: the dust inlet pipe is located behind the lead screw, the second mounting plate is detached from the cleaning box, a sealing strip is provided around the second mounting plate, and the second mounting plate is connected to the suction end of the air extractor through a mesh plate.

[0011] As a further embodiment of this utility model: eight scrapers are provided, in two groups of four, with four scrapers tilted forward around the support rod, and hanging teeth are provided on both sides of the scraper. Beneficial effects

[0012] 1. The roving frame cleaning structure for cotton yarn production provided by this utility model adjusts the roving to be positioned between the cleaning rollers, with one end passing through the yarn loop. The first and second motors are then turned on. The first motor drives the rotating head, and the drive chain connected to the rotating head rotates together. The rotating head rotates in the opposite direction, causing the cleaning rollers to rotate and carrying the lint to the other side. The second motor rotates the screw, causing the scraper to move along the screw, scraping the lint down to the bottom and cleaning the cleaning rollers. The mechanical gripping action can quickly peel off the short fibers and lint adhering to the surface of the roving and forcefully throw them to one side, achieving efficient online cleaning. The lint accumulated on the surface of the cleaning rollers is thoroughly scraped off and collected to the bottom. This cleaning process not only continuously maintains the optimal working condition of the cleaning rollers and prevents secondary pollution, but also significantly improves the cleanliness and evenness of the roving, comprehensively optimizing the subsequent yarn quality.

[0013] 2. The roving frame cleaning structure for cotton yarn production provided by this utility model collects short fibers and lint on the surface of the dust inlet pipe after they are scraped out. The dust then enters the cleaning box through an air extraction fan. The lint moves to the rear of the cleaning box by airflow and hangs on the scraper bar, concentrating in the tooth gaps of the scraper bar. This avoids the problem of short fibers being thrown up again during the cleaning of the dust extraction box. The specially designed scraper bar accurately captures the lint, and the lint is firmly stuck in the tooth gaps of the scraper bar, achieving stable aggregation. When cleaning is required, simply pull out the mounting plate to directly treat the lint on the scraper bar. This greatly reduces the airflow disturbance caused by opening the box, keeping the light short fibers under control and ensuring the roving production environment. Attached Figure Description

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0021] Please see Figure 1-5 The roving frame cleaning structure for cotton yarn production includes a first back plate 1, a first mounting plate 101 fixedly connected to the top of the first back plate 1, a wire loop 103 fixedly connected to the outer surface of the first mounting plate 101, a second back plate 102 fixedly connected to the bottom of the first back plate 1, a first motor 201 and a second motor 205 fixedly mounted on the top of the first mounting plate 101, a rotating shaft 2 fixedly connected to the output end of the first motor 201, a cleaning roller 204 fixedly connected to the outer surface of the rotating shaft 2, a rotating head 202 fixedly connected above the outer surface of the rotating shaft 2, a drive chain 203 movably connected to the outer surface of the rotating head 202, a lead screw 206 fixedly connected to the output end of the second motor 205, and a scraper 207 movably connected to the outer surface of the lead screw 206.

[0022] In actual operation, the roving is positioned between the cleaning rollers 204, with one end passing through the yarn loop 103. The first motor 201 and the second motor 205 are turned on. The first motor 201 drives the rotating head 202, and the drive chain 203 connected to the rotating head 202 rotates together. The rotating head 202 rotates in the opposite direction, causing the cleaning rollers 204 to rotate and carrying the lint to the other side. The second motor 205 rotates the screw 206, causing the scraper 207 to move on the screw 206, scraping the lint down to the bottom and cleaning the cleaning rollers 204. The mechanical gripping action can quickly peel off the short fibers and lint attached to the surface of the roving and forcefully throw them to one side, achieving efficient online cleaning. The lint accumulated on the surface of the cleaning rollers 204 is thoroughly scraped off and collected to the bottom. This cleaning process not only maintains the optimal working condition of the cleaning rollers 204 and prevents secondary pollution, but also significantly improves the cleanliness and evenness of the roving, and comprehensively optimizes the quality of subsequent yarn production.

[0023] In this embodiment, the interior of the rotating head 202 is recessed inward, and a toothed block is provided inside the rotating head 202. The rotating head 202 is connected to the drive chain 203 through the toothed block. The drive chain 203 is wrapped around the outside of the toothed block of the rotating head 202. There are two rotating heads 202, and the two rotating heads 202 rotate in opposite directions. The lead screw 206 is located on the outer side of the cleaning roller 204. The scraper 207 is moved from top to bottom on the outer surface of the lead screw 206. The scraper 207 abuts against the outer side of the cleaning roller 204. The scraper 207 is made of silicone material and can collect the lint after cleaning the roving.

[0024] Please see Figure 4-5 , A cleaning box 3 is fixedly connected to the top of the second back plate 102. A dust inlet pipe 301 is fixedly connected to the outer surface of the cleaning box 3. A second mounting plate 302 is movably connected to the back of the cleaning box 3. An air extractor 303 is fixedly installed on the back of the second mounting plate 302. A mesh plate 304 is fixedly connected inside the second mounting plate 302. A support rod 305 is fixedly connected to the outer surface of the mesh plate 304. Scraper strips 306 are fixedly connected to both sides of the support rod 305.

[0025] In actual operation, short fibers and lint are scraped out and collected on the surface of the dust inlet pipe 301. They then enter the cleaning box 3 through the air extraction fan 303. The lint moves to the rear of the cleaning box 3 by the airflow and hangs on the scraper bar 306, concentrating in the tooth gaps of the scraper bar 306. This avoids the problem of short fibers being thrown up again during the cleaning of the dust collection box. The specially designed scraper bar 306 accurately captures the lint, and the lint is firmly stuck in the tooth gaps of the scraper bar, achieving stable aggregation. When cleaning is required, simply pull out the second mounting plate 302 to directly treat the lint on the scraper bar. This greatly reduces the airflow disturbance caused by opening the box, keeping the light short fibers under control and ensuring the roving production environment.

[0026] In this embodiment, the dust inlet pipe 301 is located behind the lead screw 206. The second mounting plate 302 is detached from the cleaning box 3. Sealing strips are provided around the second mounting plate 302. The second mounting plate 302 is connected to the suction end of the air extractor 303 through the mesh plate 304. Eight scraper blades 306 are provided, in two groups of four. The four scraper blades 306 are inclined forward around the support rod 305. The sides of the scraper blades 306 are provided with hanging teeth to collect and hang light, short fibers for later processing.
