Description

Technical Field

[0001] This utility model relates to the technical field of anti-clogging structures for spinning machines, specifically, to an anti-clogging cleaning device for cotton spinning machines. Background Technology

[0002] A ring spinning frame is a spinning machine that takes semi-finished roving or sliver, drafts, twists, and winds it into a fine yarn bobbin during the spinning process. The sliver is drafted and twisted on the roving frame to form roving; the combing machine combs the fibers to form combed sliver; the carding machine combines the sliver, and the carding rack improves the sliver structure; finally, the roving is further twisted and spun into fine yarn on the ring spinning frame. During operation, the ring spinning frame conveys and transmits the yarn through rollers and a bell-shaped inlet inside the machine. The main function of the bell-shaped inlet is to guide the roving into the drafting unit of the ring spinning frame. In the ring spinning process, the roving enters the drafting unit through the guide rod and the bell-shaped inlet. The design and position of the bell-shaped inlet ensure that the roving is fed in smoothly without causing damage.

[0003] The outer end of the cotton sliver is covered with fine yarn fibers. Traditional funnel-shaped nozzles cause these fibers to get stuck at the feed inlet, leading to clogging. Simultaneously, during yarn feeding, fine fibers also adhere to the outer ends of the rollers and feed rollers. During twisting, this results in fuzz and cotton balls on the yarn surface, affecting yarn quality. To address this, a clogging prevention and cleaning device for cotton spinning machines is proposed. This device uses a funnel-shaped cleaning groove and an adsorption plate to clean the fine yarn fibers adhering to the outer ends of the yarn and feed rollers, thus resolving the aforementioned problems. Utility Model Content

[0004] This utility model proposes an anti-clogging cleaning device for cotton spinning machines, which solves the problem in related technologies where fine yarn fibers attached to the bell mouth and the outer end of the roller are difficult to clean, leading to clogging of the spinning machine.

[0005] The technical solution of this utility model is as follows:

[0006] A cleaning device for preventing clogging on a cotton spinning machine includes a mounting plate. A mounting frame is fixedly connected to the inner side of the mounting plate. A connecting shaft is rotatably connected to the inside of the mounting frame. Rollers are symmetrically fixedly connected to both ends of the connecting shaft. A feeding roller is provided at the outer end of each roller. A yarn strip is provided between the roller and the feeding roller. An anti-clogging component is provided at the outer end of the yarn strip. The anti-clogging component includes a flared opening fitted onto the outer end of the yarn strip. The flared opening is hollow and has a cleaning groove inside. An adsorption hole is formed on the inner wall of the cleaning groove. An adsorption plate is fixedly connected to the bottom end of the mounting frame. The adsorption plate is located on the bottom side of the roller and has a negative pressure chamber inside. A connecting pipe is fixedly connected and communicates with the flared opening and the adsorption plate.

[0007] Optionally, the cleaning groove inside the horn mouth has a W-shaped cross-section, and the outer end of the feeding roller is provided with several sets of teeth, with the position of the leather roller corresponding to the position of the teeth.

[0008] Optionally, the anti-clogging component further includes a conduit fixedly connected to the bottom end of the adsorption plate, the conduit being connected to the negative pressure chamber, one end of the conduit being fixedly connected to an air tube, and the conduit and the air tube being arranged perpendicularly.

[0009] Optionally, the anti-clogging component further includes an air pump fixedly connected to one end of the air pipe, and a filter cartridge is snapped into the other end of the air pipe. A filter screen is snapped into the inside of the filter cartridge, and the filter screen is provided in three sets.

[0010] Optionally, one end of the feeding roller is rotatably connected to a device plate, a servo motor is fixedly connected to one side of the device plate, a transmission pulley is fixedly connected to the output end of the servo motor, the transmission pulley is rotatably connected to the inside of the device plate, a driven pulley is rotatably connected to the inside of the device plate, a support rod is fixedly connected to the outer end of the driven pulley, and the support rod is rotatably connected to the mounting frame.

[0011] Optionally, the radius of the drive pulley is larger than the radius of the driven pulley, and a first transmission belt is sleeved between the drive pulley and the driven pulley.

[0012] Optionally, a transmission gear is fixedly connected to the outer end of the support rod, and a driven gear is engaged at the bottom end of the transmission gear. The transmission gear and the driven gear are rotatably connected inside the mounting frame.

A second transmission belt is sleeved between the first pulley and the second pulley, and the second transmission belt is located inside the mounting frame.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] In this invention, the fine yarn fibers at the outer end of the yarn are cleaned by a funnel-shaped opening with a W-shaped cross-section in the internal cleaning tank. This allows the fine yarn fibers to be collected from the adsorption holes in the cavity inside the funnel opening. At the same time, the scraper at the top of the adsorption plate cleans the fine yarn fibers attached to the outer end of the roller. The negative pressure generated by the conduit allows the fine yarn fibers to enter the filter cartridge from the air pipe and be adsorbed by the filter screen inside the filter cartridge, preventing the fine yarn fibers from flying around in the production workshop.

[0028] Example 1

[0029] Reference Figures 1-5This is the first embodiment of the present invention, which proposes an anti-clogging cleaning device for a cotton spinning machine. It includes a mounting plate 1, a mounting frame 2 fixedly connected to the inner side of the mounting plate 1, a connecting shaft 3 rotatably connected inside the mounting frame 2, and rollers 4 symmetrically fixedly connected to both ends of the connecting shaft 3. A feeding roller 5 is provided at the outer end of the roller 4, and a yarn strip 6 is provided between the roller 4 and the feeding roller 5. An anti-clogging component 7 is provided at the outer end of the yarn strip 6. The anti-clogging component 7 includes a trumpet-shaped opening 701 sleeved on the outer end of the yarn strip 6. The trumpet-shaped opening 701 is a hollow structure with a cleaning groove inside. An adsorption hole 702 is opened on the inner wall of the cleaning groove. An adsorption plate 703 is fixedly connected to the bottom end of the mounting frame 2. The adsorption plate 703 is located on the bottom side of the roller 4, and a negative pressure chamber 704 is provided inside the adsorption plate 703. A connecting pipe 705 is fixedly connected between the trumpet-shaped opening 701 and the adsorption plate 703, and they are in communication. The purpose of this arrangement is that, during the twisting process, the yarn strip 6 formed by the twisting of multiple fine yarns passes between the leather roller 4 and the feeding roller 5. At the same time, the yarn strip 6 passes through the trumpet mouth 701. The trumpet mouth 701 cleans the fine yarn fibers attached to the outer end of the yarn strip 6, so that the fine yarn fibers enter the cavity inside the trumpet mouth 701 through the adsorption hole 702 on the inner side of the trumpet mouth 701, thus preventing the phenomenon of clogging inside the trumpet mouth 701.

[0030] Optionally, the cleaning groove inside the bell mouth 701 has a W-shaped cross-section, and the outer end of the feeding roller 5 is provided with several sets of teeth, with the position of the rubber roller 4 corresponding to the teeth. The purpose of this arrangement is that the bell mouth 701 with a W-shaped cross-section prevents the fine yarn fibers from overflowing and adhering to the outer end of the cleaned yarn 6, thereby preventing uneven thickness and breakage of the yarn 6. The teeth at the outer end of the rubber roller 4 improve the feeding efficiency.

[0031] Optionally, the anti-clogging component 7 also includes a conduit 706 fixedly connected to the bottom end of the adsorption plate 703. The conduit 706 is connected to the negative pressure chamber 704, and one end of the conduit 706 is fixedly connected to an air pipe 708. The conduit 706 and the air pipe 708 are arranged perpendicularly. The purpose of this arrangement is that when the yarn 6 passes through the roller 4 and the feeding roller 5, the outer end of the roller 4 will still be covered with fine yarn fibers. At this time, the scraper at the top of the adsorption plate 703 cleans the outer end of the roller 4, causing the fine yarn fibers attached to the outer end to fall off and enter the negative pressure chamber 704 inside the adsorption plate 703.

[0032] Optionally, the anti-clogging component 7 also includes an air pump 707 fixedly connected to one end of the air pipe 708, and a filter cartridge 709 snapped onto the other end of the air pipe 708. A filter screen 7010 is snapped onto the inside of the filter cartridge 709, and the filter screen 7010 has three sets. The purpose of this arrangement is that during the cleaning of the fine yarn fibers at the outer end of the yarn sliver 6 by the bell mouth 701 and the adsorption plate 703, the airflow generated by the air pump 707 flows inside the air pipe 708, thereby creating a negative pressure inside the guide tube 706. This allows the fine yarn fibers to quickly enter the filter cartridge 709, where the filter screen 7010 adsorbs the fine yarn fibers, preventing them from being directly discharged and flying around in the workshop.

[0033] Example 2

[0034] Reference Figures 1-6 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0035] Compared to Embodiment 1, the feeding roller 5 is further rotatably connected to a device plate 8 at one end. A servo motor 9 is fixedly connected to one side of the device plate 8. A transmission pulley 10 is fixedly connected to the output end of the servo motor 9. The transmission pulley 10 is rotatably connected inside the device plate 8. A driven pulley 11 is rotatably connected inside the device plate 8. A support rod 18 is fixedly connected to the outer end of the driven pulley 11. The support rod 18 is rotatably connected to the mounting frame 2. The purpose of this arrangement is that during the feeding process, the servo motor 9 drives the transmission pulley 10 to rotate inside the device plate 8. At this time, the first transmission belt 12 drives the driven pulley 11 to rotate, thereby causing the driven pulley 11 to drive the support rod 18 to rotate inside the mounting frame 2.

[0036] Optionally, the radius of the drive pulley 10 is larger than the radius of the driven pulley 11, and a first transmission belt 12 is fitted between the drive pulley 10 and the driven pulley 11. The purpose of this arrangement is that, since the radius of the drive pulley 10 is larger than the radius of the driven pulley 11, the rotation of the support rod 18 is accelerated, thereby increasing the feeding speed of the yarn 6.

[0037] Optionally, a transmission gear 13 is fixedly connected to the outer end of the support rod 18, and a driven gear 14 meshes with the bottom end of the transmission gear 13. The transmission gear 13 and the driven gear 14 are rotatably connected inside the mounting frame 2. A first pulley 15 is symmetrically fixedly connected to the outer end of the connecting shaft 3, and a second pulley 16 is symmetrically fixedly connected to the outer end of the driven gear 14. A second transmission belt 17 is sleeved between the first pulley 15 and the second pulley 16, and the second transmission belt 17 is located inside the mounting frame 2. The purpose of this arrangement is that during the rotation of the support rod 18, the transmission gear 13 at its outer end drives the driven gear 14 to rotate. At this time, the second pulley 16 at the outer end of the driven gear 14 rotates, and the second transmission belt 17 sleeved inside the second pulley 16 drives the connecting shaft 3 connected to the first pulley 15 and the outer roller 4 to rotate. At the same time, the rotation of the roller 4 is opposite to that of the feeding roller 5, thereby causing the yarn 6 to be fed downwards.

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 solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
