[0003] The ring spinning frame is a key piece of equipment in the spinning process. It is a machine that further processes roving into fine yarn. The main function of the ring spinning frame is to uniformly lengthen and thin the fed roving to the required fineness through the drafting device, and then add appropriate twist to the drafted sliver through the twisting device, so that the yarn has certain physical and mechanical properties such as strength, elasticity and luster. Finally, the processed fine yarn is wound onto bobbins to form a bobbin of a certain shape and specification.

[0004] In the process of realizing this utility model, the inventors discovered the following problems with the existing technology: 1. The roller spacing adjustment of traditional spinning machines is not convenient enough, and the operation is complicated when loading raw materials and cleaning parts, which affects work efficiency; 2. Existing spinning machines do not have dedicated dust collection components in key processing areas, or the layout of the dust collection components is not reasonable enough, which cannot effectively collect short fibers generated at different processing stages, resulting in a lot of fiber dust in the workshop, which not only affects the workshop environment, but may also affect the normal operation of equipment and product quality.

[0008] The winding assembly consists of winding rollers, synchronous pulleys, and shims. The winding rollers are evenly distributed and rotatably connected to the bottom of the spiral shaper. Every two sets of winding rollers are connected by synchronous pulleys. The synchronous pulley consists of two sets of pulleys and a belt covering the pulleys. The shaft ends at the bottom of the winding rollers pass through the shaft center of the corresponding pulleys and are fixedly connected. The shims are respectively attached to the upper and lower ends of the synchronous pulleys and are integrally connected with the winding rollers.

[0009] More preferably, the middle traction assembly and the front traction assembly have the same structure as the rear traction assembly, and the middle traction assembly is located between the rear traction assembly and the front traction assembly.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this invention, the dust collection components are precisely laid out, allowing for accurate targeting of the source of impurities. The centrifugal fan, dust collection box, and dust collection port are connected by tightly organized pipes, reducing airflow obstruction and enabling the dust collection port to more evenly absorb lint and short fibers, effectively improving the dust collection effect. The dust collection box and dust collection port adopt a detachable structure, and the dust collection box has a door panel connected by a hinge, facilitating the collection and thorough cleaning of internal impurities. At the same time, the top cover effectively reduces the possibility of short fibers overflowing, further ensuring a clean production environment. This efficient dust collection system reduces the adhesion of impurities to the equipment and their potential impact on yarn quality, extends the service life of the equipment, and improves product quality.

[0017] In this invention, the roller spacing is adjustable. By rotating the screw, the spacing between the upper and lower rollers can be easily adjusted. Simultaneously, the embedded engagement of the shaped shaft and the second bevel gear ensures synchronous movement of the upper and lower rollers, guaranteeing uniform tension on the yarn between them. This effectively prevents uneven yarn thickness and facilitates initial feeding and cleaning of fibers from the roller surface grooves. Furthermore, the height of the tension roller can be adjusted via the push rod assembly. Operators can precisely adjust the tension based on fiber material characteristics using the synergistic action of cylinders and air spring hydraulic rods, ensuring yarn quality and stability. The pressing component can be separated from the lower roller surface via a moving frame, greatly facilitating component cleaning and initial feeding. These adjustable functions work together to enable the equipment to quickly adapt to changes in different yarn specifications and production tasks, improving production efficiency and product quality.

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 6 This utility model provides a technical solution: a spinning machine with convenient internal dust collection, including an operating table 1. A rear traction assembly 2, a middle traction assembly 3, and a front traction assembly 4 are fixedly connected to the top of the operating table 1. Tensioning rollers 5 are provided between the rear traction assembly 2 and the middle traction assembly 3, and between the middle traction assembly 3 and the front traction assembly 4. Both ends of the tensioning rollers 5 are fixedly connected to the top of a push rod assembly 6. The bottom of the push rod assembly 6 is fixed to the surface of the operating table 1 with bolts. A pressing component 7 is provided on one side of the front traction assembly 4, and a collector 13 is fixedly connected to the other side of the front traction assembly 4. The pressing component 7 rotates on the moving part. Between the moving frames 8, the moving frame 8 slides in the corresponding groove on the surface of the operating table 1 via the slider at its bottom. Inside the operating table 1, dust collection components 9 are provided at the positions corresponding to the rear traction component 2, the middle traction component 3, and the front traction component 4. The surface of the operating table 1 is connected to a top cover 10 by bolts. The top cover 10 is located on top of the operating table 1 in a covering form and is above the other components on the surface of the operating table 1. A spiral shaper 11 is fixedly connected to one side of the outer wall of the operating table 1. A winding component 12 is provided below the spiral shaper 11. The spiral shaper 11 and the winding component 12 are on the same side as the front traction component 4 and located below it.

[0027] The rear traction assembly 2 is bolted to the surface of the operating table 1 via its support frame 201. A lower roller 202 is rotatably connected between the support frames 201. An upper roller 203 is positioned above the lower roller 202 and rotates between the adjusting frames 204. Two sets of vertically distributed and meshing first bevel gears 205 and second bevel gears 206 are rotatably connected to the inside of one side of the support frame 201 and one side of the adjusting frame 204. The shaft ends of the upper roller 203 and the lower roller 202 pass through the corresponding first bevel gears 205 and second bevel gears 206. A bevel gear 205 is fixedly connected at the shaft center, and the shaft ends of the upper roller 203 and the lower roller 202 are rotatably connected to the inner walls of their corresponding adjusting frame 204 and support frame 201 respectively through bearings. The second bevel gear 206 is connected to each other through a special-shaped shaft 207 passing through its shaft center. The special-shaped shaft 207 is rotatably connected to the inside of the support frame 201. A screw 208 is threadedly connected to the center point of the top of the support frame 201. One end of the screw 208 passes through the support frame 201 and is rotatably connected to the top of the adjusting frame 204.

[0028] The vacuuming assembly 9 consists of a vacuum box 901 and a vacuum port 902. The vacuum box 901 is slidably connected to a cavity corresponding to one side of the outer wall of the operating table 1. One end of the vacuum port 902 is connected to the top of the vacuum box 901 through a pipe thread, and the other end of the vacuum port 902 is attached to the surface of the operating table 1. A centrifugal fan 903 is fixedly connected to the outer wall of the vacuum box 901.

[0029] The winding assembly 12 consists of a winding roller 1201, a synchronous pulley 1202, and a gasket 1203. The winding rollers 1201 are evenly distributed and rotatably connected to the bottom of the spiral shaper 11. Each pair of winding rollers 1201 is connected by a synchronous pulley 1202. The synchronous pulley 1202 consists of two pulleys and a belt covering the pulley. The shaft ends at the bottom of the winding rollers 1201 pass through the shaft center of the corresponding pulley and are fixedly connected. The gaskets 1203 are respectively attached to the upper and lower ends of the synchronous pulley 1202 and are integrally connected with the winding rollers 1201.

[0030] In this embodiment, as Figure 1 and Figure 2As shown, the middle traction component 3 and the front traction component 4 have the same structure as the rear traction component 2, and the middle traction component 3 is located between the rear traction component 2 and the front traction component 4. The height of the middle traction component 3 is lower than that of the rear traction component 2 and the front traction component 4, while the rear traction component 2 and the front traction component 4 have the same height. The rear traction component 2 and the front traction component 4 have the same height, which can provide balanced tension at the front and rear ends of the yarn, while the lower-height middle traction component 3 can provide moderate traction to the middle of the yarn. This layout forms a stable triangular support structure, which can better disperse the tension of the yarn on the traction component during the yarn traction process, and prevent the yarn from having excessive or insufficient local tension during the movement, thereby ensuring uniform tension of the entire yarn and improving the quality and stability of the yarn.

[0031] In this embodiment, as Figure 4 and Figure 5 As shown, the second bevel gears 206 are symmetrically distributed, and the outer wall of the irregular shaft 207 adjacent to the upper roller 203 is provided with a strip-shaped protrusion. The inner wall of the second bevel gear 206 at one end of the upper roller 203 is correspondingly provided with a slot for embedding and engaging the strip-shaped protrusion on the surface of the irregular shaft 207, forming a sliding connection with it. Simultaneously, the upper roller 203 and the lower roller 202 rotate relative to each other. The upper roller 203 forms a lifting structure at the top of the lower roller 202 via a screw 208 at the top of the adjusting frame 204. Both ends of the support frame 201 are supported by shafts, which penetrate the adjusting frame 204 and form a sliding connection with it. The irregular shaft 207 and the second bevel gear 206 at one end of the upper roller 203 are connected by the strip-shaped protrusion and the slot. This design effectively prevents slippage during transmission, ensuring that the upper roller 203 accurately follows the movement of the shaped shaft 207, thereby achieving synchronous movement between the upper roller 203 and the lower roller 202. This ensures that the yarn experiences uniform tension between the rollers, effectively preventing uneven yarn thickness and greatly improving yarn uniformity. Furthermore, this special structure allows for height adjustment of the upper roller 203. When adjusting yarn specifications or handling different production tasks, operators can easily adjust the height of the upper roller 203 with simple operations. This is extremely convenient for initial feeding and for cleaning fibers stuck in the grooves on the surfaces of the upper roller 203 and lower roller 202 during subsequent maintenance.

[0032] In this embodiment, as Figure 1 and Figure 2As shown, the shaft head at one end of the tension roller 5 is fixedly connected to the output end of the servo motor, and the push rod assembly 6 consists of a cylinder and a gas spring hydraulic rod. The cylinder is located at one end of the tension roller 5, and the gas spring hydraulic rod is located at the other end of the tension roller 5. By applying tension to the yarn through the tension roller 5, the cohesion between fibers is enhanced, thereby improving the internal structure of the yarn. This not only improves the strength and abrasion resistance of the yarn, but also makes the yarn surface smoother, reduces fuzz, and improves the appearance quality and hand feel of the yarn. The cylinder and the gas spring hydraulic rod are located at both ends of the tension roller 5, respectively. This layout allows the tension force to be evenly distributed on the tension roller 5, avoiding the uneven force on the tension roller 5 caused by the tension force being concentrated at one end, and further improving the quality of the yarn.

[0033] In this embodiment, as Figure 1 and Figure 2 As shown, the top cover 10 is composed of a metal frame and acrylic sheets embedded in the inner wall of the frame. The top cover 10 has a two-part structure, and each half is connected by a hinge with a flap, which is located directly above the screw 208. The exposed spinning machine is easily invaded by dust, debris and other external substances, which affects the normal operation of the equipment and the quality of the yarn. By setting up the top cover 10, the maximum area of ​​the traction area is covered, avoiding the contamination of the yarn by dust, debris and other substances. The flap design provides sufficient operating space when it is necessary to operate on the top of the spinning machine or the screw 208 or its surroundings. After the operation is completed, the flap can be easily closed to restore the protective state of the equipment. The whole process is simple and quick, saving operation time.

[0034] In this embodiment, as Figure 6 As shown, both the collector 13 and the suction port 902 are trumpet-shaped, and a slot is threaded through the top of the operating table 1 to connect the pipe below the suction port 902 to the dust collection box 901. One end of the centrifugal fan 903 is connected to the dust collection box 901 through a pipe, and a filter screen 904 is threadedly connected to the inner wall of the dust collection box 901 corresponding to the pipe of the centrifugal fan 903. The centrifugal fan 903 is connected to the dust collection box 901 through a pipe, and the dust collection box 901 is connected to the suction port 902 through a pipe. This tight and orderly pipe connection reduces the bends and obstructions in the airflow transmission process, which helps to more evenly adsorb flying lint and short fibers and improve the dust collection effect. The detachable structure of the dust collection box 901 and the suction port 902, as well as the door panel set by the hinge, allows the internal impurities to be collected and processed. The reasonable distribution of the dust collection components 9 allows them to accurately target the source of impurities, reduce the adhesion of impurities on the equipment, and reduce the potential impact on yarn quality.

[0035] In this embodiment, as Figure 1As shown, the rolling component 7 consists of a steel ring and a rubber pad covering the outer wall of the steel ring. The rolling component 7 is closely connected to the lower roller 202 in the front traction assembly 4, forming a relative movement. One end of the moving frame 8 is threadedly connected to a corresponding slot on the surface of the operating table 1 via a quick-release bolt. The steel ring inside the rolling component 7 has high strength and rigidity, providing stable support for the rolling process and ensuring that it can withstand greater pressure without deformation when moving relative to the lower roller 202. The outer rubber pad has good elasticity and friction, which can closely adhere to the yarn, making the yarn evenly stressed during the rolling process. This effectively improves the surface quality of the yarn, making it smoother and flatter, reducing defects and irregularities on the yarn surface, and further protecting the yarn. The rolling component 7 can be separated from the surface of the lower roller 202 via the moving frame 8, which greatly facilitates the thorough cleaning of the surfaces of both components and the initial feeding of materials.

[0036] The method of use and advantages of this utility model: This spinning machine, which facilitates internal dust collection, operates as follows:

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the opened fiber raw material is first conveyed by an external feeding device, then passed through the rear traction assembly 2, and then processed by the middle traction assembly 3. Next, it is introduced into the front traction assembly 4 via the collector 13. The distance between the upper roller 203 and the lower roller 202 is adjustable. Rotating the screw 208 causes the adjusting frame 204 to rise with the screw 208, widening the distance between the upper roller 203 and the lower roller 202. At this time, the first bevel gear 205 and the second bevel gear 206 at one end of the upper roller 203 rise simultaneously. Since the second bevel gear 206 is embedded and engaged with the shaped shaft 207, the second bevel gear 206 can slide along the surface of the shaped shaft 207 to adjust its position. After adjusting to the appropriate position, the shaped shaft 207 can drive the second bevel gear 206 through the embedded strip-shaped protrusion. The bevel gear 206 rotates, which in turn drives the first bevel gear 205 on the other side of the upper roller 203 to rotate, realizing the relative movement between the upper roller 203 and the lower roller 202, so that the fiber can be transferred between them. During the traction process, the height of the tension roller 5 is adjusted by the push rod assembly 6. The processing personnel can adjust it according to the characteristics of the fiber material. When the power output end of one side of the cylinder is pushed as the active drive end, the air spring hydraulic rod on the other side is driven as the driven part to achieve the same direction of movement. The processed fiber passes through the collector 13 and the yarn formed by the fiber conveyed by the front traction assembly 4 is drawn out in the gap between the crushing part 7 and the lower roller 202 at one end of the front traction assembly 4. During this process, the yarn is crushed by the crushing part 7. Further compaction and finishing are carried out. Simultaneously, because the servo motor speed of the front traction component 4 is higher than that of the rear traction component 2 and the middle traction component 3, the yarn is twisted during movement, causing the fibers to intertwine and bind more tightly. Finally, it is wound up by the horizontally rotating winding roller 1201. The surface of the winding roller 1201 is fitted with a drum for winding the fine yarn. During yarn processing, short fibers may detach. Multiple sets of distributed suction ports 902, under the airflow generated by the centrifugal fan 903, draw the short fibers into the suction box 901. The filter screen 904 effectively prevents short fibers from entering the centrifugal fan 903. The presence of the top cover 10 reduces the possibility of short fiber spillage. The top cover 10 is equipped with a hinged flap. During the initial traction... The screw 208 can be flipped during operation. A slot for the recessed sliding installation of the vacuum box 901 is provided on one side of the operating table 1. The vacuum box 901 can be removed for cleaning during maintenance. The sum of the widths of the two sets of flip plates at the top of the top cover 10 matches the width of the corresponding vacuum ports 902 below. The flip plates can be flipped to disassemble the corresponding vacuum ports 902 at the top of each vacuum assembly 9 one by one. By rotating the vacuum port 902, it can be detached from the top of the vacuum box 901 and pulled out from the slot at the top of the operating table 1. The vacuum box 901 is connected to a door panel via a hinge, allowing for thorough cleaning of the trapped fibers inside. It should be noted that for the first operation of this equipment, the opened fiber material must be manually passed through the rear traction assembly 2 and the middle traction assembly 3 in sequence.The feed is introduced into the front traction assembly 4 via the collector 13 between the upper roller 203 and the lower roller 202. Simultaneously, the distance between the upper roller 203 and the lower roller 202, as well as the height of the tension roller 5, are adjusted as needed before starting the equipment.
