Description

Technical Field

[0001] This invention relates to the field of textile accessory processing technology, specifically to a yarn tube polishing device and its working method. Background Technology

[0002] Yarn tubes are core components in textile production, primarily used for winding and storing yarn. Their surface smoothness and flatness directly affect the quality of yarn winding, effectively preventing problems such as yarn fuzzing, breakage, and winding disorder. After injection molding or long-term use, yarn tubes are prone to developing burrs, unevenness, and oxide layers on their surface. Therefore, they must undergo a polishing and finishing process to meet the standards of high-speed textile production. Currently, in large-scale textile production, yarn tube polishing largely relies on traditional polishing equipment or manual methods, which have significant limitations in adaptability and operation, making them difficult to meet the demands of modern mass production.

[0003] Existing traditional yarn tube polishing equipment has many shortcomings in actual use. First, the clamping structure of conventional polishing equipment is mostly a rigid fixed structure, which can only be adapted to a single specification of yarn tube. It cannot adaptively adjust the clamping size according to yarn tubes with different inner diameters, resulting in poor versatility. Moreover, rigid clamping is prone to squeezing and damaging the inner wall of the yarn tube, resulting in a high scrap rate. Second, the pressure of traditional abrasive belt polishing structure is fixed, and it is impossible to finely adjust the polishing pressure according to the material and thickness of the yarn tube. Excessive polishing pressure can easily wear through the surface of the yarn tube, while insufficient pressure will result in incomplete polishing. At the same time, the poor adhesion of the abrasive belt during operation makes it easy to have polishing dead corners and uneven polishing.

[0004] In addition, existing grinding equipment has a single function, relying solely on the operation of a single belt to perform grinding operations, resulting in low grinding efficiency and difficulty in meeting the needs of batch processing. At the same time, the grinding process generates a large amount of dust and debris, and traditional equipment lacks a proper dust collection structure. The dust not only pollutes the working environment but also easily accumulates on the surface of the equipment's transmission components, accelerating equipment wear and shortening its service life. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a yarn tube polishing device and its working method, which solves the technical problems of poor adaptability, unadjustable polishing pressure, uneven polishing, presence of polishing dead corners, low processing efficiency, and easy contamination of the equipment by polishing dust in existing yarn tube polishing devices.

Spring plates are fixedly installed on both sides of the interior of the first cavity, and the ends of the spring plates extend into the interior of the rotating frame on the corresponding side. Pressure rollers are fixedly installed on the inner wall side of each rotating frame, and the inner ends of the pressure rollers abut against the outer surface of the spring plates on the corresponding side.

[0007] Preferably, a lifting cylinder is fixedly installed on the other side of the top of the linear motion module drive end slide, and the drive end of the lifting cylinder is fixedly installed on the bottom side of the bending arm.

[0008] Preferably, a geared motor is fixedly installed at the end of the fixed seat away from the movable seat, a main shaft is fixedly installed at the drive end of the geared motor, keyways are provided on both sides of the inner wall of the rotating drum, and splines are fixedly installed at both ends of the main shaft, with the outer ends of the splines movably disposed inside the keyways on the corresponding sides.

[0009] Preferably, a first chuck is fixedly installed on the outer diameter of the middle part of the spindle, and a second chuck is fixedly installed on the end of the movable seat near the fixed seat. Several hemispherical protrusions are fixedly installed on the inner ends of the first chuck and the second chuck, and the two sets of hemispherical protrusions are staggered. The four corners of the inner ends of the fixed seat and the movable seat are connected by a return spring.

[0010] Preferably, each of the fixed frames has a second cavity inside. A short shaft is movably installed on the bottom wall of each of the second cavities. A driven bevel gear is fixedly installed at the top of each short shaft. An internal hexagonal adjusting nut is movably installed on one side of each fixed frame. The inner end of each internal hexagonal adjusting nut extends into the interior of the second cavity and is fixedly installed with a driving bevel gear. The inner ends of the driven bevel gear and the driving bevel gear are meshed and connected. The bottom end of each short shaft extends into the interior of the corresponding first cavity and is fixedly installed with a threaded rod. A support platform is movably installed in the middle of each of the first cavities, and both sides of the support platform abut against the inner surface of the spring sheet. The middle part of each support platform is threadedly connected to the outer diameter of the threaded rod.

[0011] Preferably, a side fixing platform is fixedly installed on one side of the top of the processing table, an inner cylinder is fixedly installed on one side of the top of the side fixing platform, an outer cylinder is movably installed on the outer end of the inner cylinder, and a telescopic cylinder is fixedly installed inside the inner cylinder, with the driving end of the telescopic cylinder fixedly connected to the inside of the outer cylinder via a connecting rod.

[0012] Preferably, a plurality of first scissor bars are uniformly and movably installed on the outer diameter of the inner cylinder, and a plurality of second scissor bars are uniformly and movably installed on the outer diameter of the outer cylinder. The ends of the first and second scissor bars on the corresponding sides are movably installed on both sides of the outer support plate. A plurality of abutment arms are uniformly and movably installed on the outer surface of the outer support plate through a coil spring, and a damping ball is movably installed at the end of each abutment arm.

[0013] Preferably, a dust extraction box is fixedly installed on the front side of the top of the processing table, an air pump is fixedly installed on one side of the dust extraction box, and a control panel is fixedly installed on the top of the processing table near the dust extraction box.

[0014] A method for polishing yarn tubes includes the following steps:

[0015] Step 1: Start the telescopic cylinder to drive the outer cylinder to move. In conjunction with the first and second scissor rods, the outer support plate is extended and retracted to adjust the size. The inner wall of the yarn tube is flexibly damped and clamped by the coil spring and the damping ball at the end of the contact arm. It can adapt to yarn tubes of different specifications and limit the movement at low speed, laying the foundation for uniform polishing.

[0016] Step 2: Drive the bending arm down through the lifting cylinder so that the sanding belt fits against the surface of the yarn tube. The yarn tube lifts the sanding belt, causing the rotating frame to rotate. The pressure roller squeezes the spring plate to form constant pressure support. At the same time, the internal hexagonal adjusting nut can be rotated to adjust the position of the support platform through the bevel gear and threaded rod, and the sanding pressure can be precisely adjusted.

[0017] Step 3: Start the geared motor, which drives the grinding belt to rotate at high speed via the spindle and spline. The first chuck, the second chuck, and the return spring work together to achieve high-frequency vibration of the grinding belt. Then, the linear motion module completes axial all-round grinding. At the same time, the air pump is started to collect the grinding dust in conjunction with the dust collection box.

[0018] This invention provides a yarn tube polishing device and its working method. It has the following beneficial effects:

[0019] 1. This invention uses a telescopic cylinder, scissor bar, outer support plate, coil spring, contact arm and damping ball structure to adaptively adjust the clamping size according to different yarn tube inner diameters; it adopts a soft clamping method to fit the inner wall of the yarn tube without damaging the workpiece surface, and at the same time, it uses the damping ball to buffer and decelerate, so that the yarn tube moves at a low speed, ensuring circumferential and uniform grinding.

[0020] 2. This invention utilizes a linkage structure of spring sheet, pressure roller, and rotating frame. When the yarn tube lifts the abrasive belt, it can automatically adapt to deformation and apply pressure. By sliding the pressure roller to change the lever arm, it compensates for changes in the elasticity of the spring sheet, thus maintaining a stable abrasive belt pressure on the yarn tube. At the same time, the bending fulcrum of the spring sheet can be adjusted by adjusting the internal hexagonal adjusting nut, bevel gear, threaded rod, and support platform to precisely adjust the abrasive pressure and adapt to the abrasive needs of yarn tubes of different materials and specifications.

[0021] 3. This invention uses a geared motor to drive the sanding belt to circulate at high speed via spline transmission. At the same time, the first and second chucks rely on the staggered hemispherical protrusion tooth structure and the return spring to drive the sanding belt to vibrate back and forth. The high-speed sanding belt movement superimposed with the reciprocating vibration greatly improves the sanding efficiency and produces a uniform sanding texture without any sanding dead corners. Combined with a linear motion module to realize the translation of the sanding belt, it can complete the continuous sanding of the yarn tube in all directions along the axial direction.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example:

[0033] Please see the appendix Figure 1 -Appendix Figure 8 This invention provides a yarn tube polishing device, such as... Figure 1 As shown, the equipment includes a processing table 1, which serves as the supporting base for the entire equipment and provides a stable support foundation for the installation and operation of all parts of the equipment. This ensures the overall stability of the grinding mechanism, clamping mechanism, and dust removal mechanism during operation. A linear motion module 2 is fixedly installed on the top rear side of the processing table 1. The linear motion module 2 is the horizontal displacement drive mechanism of the equipment, which can drive the upper grinding structure to achieve horizontal translational movement. This helps to complete the grinding operation of the yarn tube along the entire axial direction and achieve all-round uniform grinding of the outer surface of the yarn tube.

[0034] A vertical slide rail 3 is fixedly installed on one side of the top of the linear motion module 2 drive end slide table. The vertical slide rail 3 provides guidance and limit for the vertical movement of the bending arm 4, ensuring the accuracy of the vertical lifting and lowering movement of the bending arm 4, avoiding deviation and jamming during the lifting and lowering process, and stabilizing the grinding feed stroke. One side of the vertical slide rail 3 is movably installed on the lower part of the bending arm 4. As the core load-bearing connecting component of the grinding mechanism, the bending arm 4 plays the role of transfer transmission and support fixation. It can follow the vertical guide structure to complete the lifting and lowering action, and at the same time bear the grinding components at the end, realizing the overall lifting and lowering feed operation of the grinding mechanism.

[0035] A fixed seat 6 is fixedly installed at the end of the bending arm 4. The fixed seat 6 is a fixed-side bearing base used to install and fix the drive component. A movable seat 7 is provided on one side of the fixed seat 6. The movable seat 7 is an adjustable bearing base that can move back and forth slightly relative to the fixed seat 6. This, in conjunction with the vibration structure, realizes the high-frequency reciprocating vibration of the sanding belt 22, improving the uniformity and efficiency of sanding the yarn tube surface. A rotating drum 9 is movably installed inside the movable seat 7. The rotating drum 9 serves as a power transmission adapter and can rotate synchronously with the main shaft 12, while also bearing the drive wheel 10. The rotating drum 9 completes its rotational motion, achieving a stable transmission of grinding power. A drive wheel 10 is fixedly installed at the end of the drum 9 furthest from the fixed base 6. The drive wheel 10 is the active drive component for the sanding belt, receiving power from the drum 9 and rotating at high speed. Together with the driven wheel 21, it drives the sanding belt 22 to circulate, providing core power for the grinding operation. Inclined connecting arms 18 are fixedly installed on both sides of the bottom of the movable base 7. The inclined arrangement of the connecting arms 18 stably connects the movable base 7 to the bottom fixed frame 19, ensuring grinding support on both sides. The symmetry of the structure distributes the stress during operation, improving the overall stability of the structure. Each end of the connecting arm 18 is fixedly equipped with a mounting bracket 19. The mounting bracket 19 serves as the mounting carrier for the bottom adjustment and buffer structure, accommodating core components such as the spring plate 23, pressure roller 24, and bevel gear adjustment assembly. A rotating bracket 20 is movably mounted at the bottom of each mounting bracket 19. The rotating bracket 20 is a rotatable and adjustable support component that can adaptively rotate as the sanding belt is pressed, driving the driven wheel 21 to finely adjust its position to fit the curved outer surface of the yarn tube. One end of each wheel is movably mounted with a driven wheel 21. The driven wheel 21 is a driven support and guide component of the abrasive belt 22. It cooperates with the drive wheel 10 to form a triangular support structure, which tensions and supports the abrasive belt 22. At the same time, it rotates synchronously with the abrasive belt 22. The outer diameters of the drive wheel 10 and the two driven wheels 21 are connected by the abrasive belt 22. The abrasive belt 22 is a grinding execution component that directly contacts the yarn tube. Through high-speed circulation and high-frequency vibration, it grinds and polishes the outer surface of the yarn tube to remove surface burrs and defects and optimize the surface flatness of the yarn tube.

[0036] Each fixed frame 19 has a first cavity 25 at its bottom. The first cavity 25 is a cavity for receiving the internal buffer adjustment structure. Spring plates 23 are fixedly installed on both sides of the first cavity 25, and the ends of the spring plates 23 extend into the interior of the corresponding rotating frame 20. The spring plates 23 are adaptive elastic buffer components with a multi-layered structure. They can generate elastic deformation with the rotation of the rotating frame 20, providing stable reverse elastic force so that the abrasive belt 22 always adheres to the surface of the yarn tube. At the same time, adaptive compensation of the abrasive pressure is achieved. Pressure rollers 24 are fixedly installed on the inner wall of the rotating frame 20, and the inner ends of the pressure rollers 24 abut against the outer surface of the corresponding spring plates 23. The pressure rollers 24 are elastic force adjustment transmission components. They can move synchronously with the rotation of the rotating frame 20 and slide on the surface of the spring plates 23 to change the force arm of the spring plates 23, compensate for the elastic force change, and ensure that the abrasive pressure is constant and uniform.

[0037] In this embodiment, a lifting cylinder 5 is fixedly installed on the other side of the top of the linear motion module 2 drive end slide, and the drive end of the lifting cylinder 5 is fixedly installed on the bottom side of the bending arm 4. The lifting cylinder 5 is the vertical feed drive component of the grinding mechanism, which can accurately drive the bending arm 4 to complete the lifting action along the vertical slide rail 3.

[0038] Furthermore, a geared motor 11 is fixedly installed at the end of the fixed seat 6 away from the movable seat 7. The geared motor 11 is the core power source of the equipment, which can output stable rotational power and adapt to the speed requirements of grinding operations. It avoids the grinding quality from being too fast or too slow and ensures the smooth operation of the sanding belt. A main shaft 12 is fixedly installed at the drive end of the geared motor 11. The main shaft 12 is the core shaft of the power transmission and can receive the power of the geared motor 11 to rotate synchronously. It also integrates the transmission and vibration drive structure, and synchronously drives the rotating drum 9 and the first chuck 15 to operate, realizing dual operation functions. Keyways 14 are opened on both sides of the inner wall of the rotating drum 9. Splines 13 are fixedly installed at both ends of the main shaft 12, and the outer ends of the splines 13 are movably set inside the corresponding keyways 14. The keyways 14 and splines 13 cooperate to form a limiting transmission structure, which restricts the relative rotation of the rotating drum 9 and the main shaft 12, ensures the synchronization of power transmission, avoids transmission slippage, and improves power transmission efficiency.

[0039] Furthermore, a first chuck 15 is fixedly installed on the outer diameter of the middle part of the spindle 12. The first chuck 15 is a vibration-driven active component that rotates synchronously with the spindle 12. It cooperates with the second chuck 16 through an end protrusion structure to continuously generate a reciprocating pushing force. The second chuck 16 is fixedly installed on the end of the movable seat 7 near the fixed seat 6. The second chuck 16 is a vibration-driven driven component that corresponds to and cooperates with the first chuck 15 to receive the pushing force, driving the movable seat 7 to move back and forth, thereby achieving the vibration grinding effect of the abrasive belt 22. The first chuck 15 and the second chuck 16... Several hemispherical protrusions 17 are fixedly installed on the inner end, and the two sets of hemispherical protrusions 17 are staggered. The staggered hemispherical protrusions 17 form a tooth linkage structure. During rotation, they continuously and alternately fit and separate to achieve continuous and stable reciprocating pushing action, ensuring uniform and stable vibration frequency. The four corners of the inner ends of the fixed seat 6 and the movable seat 7 are connected by a return spring 8. The return spring 8 is a vibration return component. After the protrusion pushes and causes displacement, it can quickly pull the movable seat 7 to return to its original position. With the help of the chuck structure, high-frequency and continuous left and right reciprocating vibration is achieved, improving the uniformity of grinding.

[0040] Furthermore, each of the fixed frames 19 has a second cavity 26 inside. A short shaft 27 is movably mounted on the bottom wall of each second cavity 26. The short shaft 27 is a power transfer vertical shaft, receiving the rotational power of the bevel gear set and driving the bottom threaded rod 31 to rotate synchronously, achieving vertical power transfer. A driven bevel gear 28 is fixedly mounted on the top of each short shaft 27. The driven bevel gear 28 is a driven transmission gear that meshes with the driving bevel gear 30, receiving rotational power and driving the short shaft 27 to rotate, completing the power transfer. An internal hexagonal adjusting nut 29 is movably mounted on one side of each fixed frame 19. The internal hexagonal adjusting nut 29 is a manual adjustment control component, which can be manually rotated to provide a manual adjustment entry for pressure adjustment, adapting to the grinding pressure requirements of different yarn tubes. The inner end of the internal hexagonal adjusting nut 29 extends into the second cavity 26 and is fixedly mounted with a driving bevel gear 30. The driving bevel gear 30 is a driving transmission gear that rotates synchronously with the adjusting nut, engaging in a meshing action. The driven bevel gear 28 is driven to rotate, realizing the transmission of adjustable power. The inner ends of the driven bevel gear 28 and the driving bevel gear 30 are meshed and connected. The bottom end of the short shaft 27 extends into the interior of the corresponding first cavity 25 and is fixedly installed with a threaded rod 31. The threaded rod 31 is a lifting and adjusting transmission component, which rotates synchronously with the short shaft 27. Through the threaded transmission, it drives the support platform 32 to rise and fall smoothly, realizing the adjustment of the fulcrum position. The support platform 32 is movably installed in the middle of the first cavity 25, and both sides of the support platform 32 abut against the inner surface of the spring plate 23. The support platform 32 is a force fulcrum adjustment component of the spring plate 23. By raising and lowering, the bending force fulcrum of the spring plate 23 is changed, thereby adjusting the magnitude of the elastic force generated by the deformation of the spring plate 23. The middle part of the support platform 32 is threaded to the outer diameter of the threaded rod 31. The threaded connection structure has a self-locking characteristic. After adjustment, the position of the support platform 32 can be fixed to prevent the fulcrum from shifting during operation and to ensure the stability and adjustability of the grinding pressure.

[0041] Furthermore, a side fixing platform 33 is fixedly installed on one side of the top of the processing table 1. The side fixing platform 33 is a dedicated mounting base for the yarn tube clamping mechanism, which stably supports the inner cylinder 34, the outer cylinder 35 and the clamping components, ensuring the stability of the yarn tube clamping and positioning. The inner cylinder 34 is fixedly installed on one side of the top of the side fixing platform 33. The outer cylinder 35 is movably installed on the outer end of the inner cylinder 34. The outer cylinder 35 is a telescopic and adjustable movable base, which can perform left and right telescopic displacement relative to the inner cylinder 34, driving the scissor structure to move and realize adaptive adjustment of the clamping outer diameter. A telescopic cylinder 36 is fixedly installed inside the inner cylinder 34, and the driving end of the telescopic cylinder 36 is fixedly connected to the inside of the outer cylinder 35 through a connecting rod. The telescopic cylinder 36 is a driving component for clamping adjustment, which drives the outer cylinder 35 to move through telescopic movement.

[0042] Furthermore, several first scissor rods 37 are evenly and movably installed on the outer diameter of the inner cylinder 34, and several second scissor rods 38 are evenly installed on the outer diameter of the outer cylinder 35. The first scissor rods 37 are fixed-side support transmission rods, and the second scissor rods 38 are movable-side transmission rods. They move synchronously with the extension and retraction of the outer cylinder 35, and change the opening and closing angle in conjunction with the first scissor rods 37 to precisely adjust the outer support diameter. The ends of the corresponding first scissor rods 37 and second scissor rods 38 are movably installed on both sides of the outer support plate 39. The outer support plate 39 is the core plate for supporting and clamping the inner wall of the yarn tube. Through multiple sets of synchronous opening and closing... The outer support plate 39 is adapted to yarn tubes with different inner diameter specifications to achieve precise positioning and support. Several abutment arms 41 are evenly and movably installed on the outer surface of the outer support plate 39 through coil springs 40. The coil springs 40 are elastic buffer components that provide elastic support force for the abutment arms 41 to achieve a flexible clamping effect and avoid damage to the inner wall of the yarn tube by rigid clamping. Damping balls 42 are movably installed at the ends of the abutment arms 41. The damping balls 42 are flexible damping clamping components that can closely fit the inner wall of the yarn tube and generate damping resistance to slow down the rotation speed of the yarn tube with the sanding belt, achieve low-speed follow-up, and ensure comprehensive and dead-angle-free sanding.

[0043] Furthermore, a dust collection box 43 is fixedly installed on the front top of the processing table 1. The dust collection box 43 is a dust collection and gathering component that can cover the grinding operation area. A filter screen is installed inside to collect the dust and debris generated during the grinding process, achieving centralized dust collection. An air pump 44 is fixedly installed on one side of the dust collection box 43. The air pump 44 is the dust suction power source. When running, it generates negative pressure suction, which allows the dust and debris generated during grinding to quickly enter the dust collection box 43, achieving dust-free grinding operation. A control panel 45 is fixedly installed on the top of the processing table 1 near the dust collection box 43. The control panel 45 is the centralized control component of the equipment, which can uniformly control all operation actions of the equipment, such as lifting, moving, clamping, grinding, and dust collection.

[0044] A method for polishing yarn tubes includes the following steps:

[0045] Step 1: Start the telescopic cylinder 36 to drive the outer cylinder 35 to move. In conjunction with the first scissor bar 37 and the second scissor bar 38, drive the outer support plate 39 to extend and retract to adjust the size. Use the coil spring 40 and the damping ball 42 at the end of the contact arm 41 to flexibly dampen and clamp the inner wall of the yarn tube, adapt to different specifications of yarn tubes and limit the movement at low speed, laying the foundation for uniform polishing.

[0046] Step 2: The bending arm 4 is driven to move down by the lifting cylinder 5, so that the sanding belt 22 fits against the surface of the yarn tube; the yarn tube lifts the sanding belt 22, causing the rotating frame 20 to rotate, and the pressure roller 24 squeezes the spring plate 23 to form constant pressure support. At the same time, the internal hexagonal adjusting nut 29 can be rotated to adjust the position of the support platform 32 through the bevel gear and threaded rod 31, and the sanding pressure can be precisely adjusted.

[0047] Step 3: Start the geared motor 11, which drives the grinding belt 22 to rotate at high speed via the main shaft 12 and spline 13. The high-frequency vibration of the grinding belt is achieved with the help of the first chuck 15, the second chuck 16 and the return spring 8. The axial all-round grinding is then completed through the linear motion module 2. At the same time, the air pump 44 is started to collect the grinding dust with the dust collection box 43.

[0048] Working principle:

[0049] First, the telescopic cylinder 36 drives the outer cylinder 35 to move left and right. As the outer cylinder 35 moves, it causes one end of each of the second scissor arms 38 to move accordingly. Combined with the action of the first scissor arm 37, this causes all the outer support plates 39 to move synchronously inward or outward, thus adapting to the inner diameter of the yarn tube. Then, the yarn tube to be polished is inserted. After insertion, the damping balls 42 at the ends of all the contact arms 41, under the action of the coil spring 40, will tightly adhere to the inner wall of the yarn tube, achieving soft clamping. Furthermore, during the high-speed movement of the subsequent polishing belt 22, the power of the polishing belt 22 is transmitted to the yarn tube itself. Using the damping balls 42, the movement speed of the yarn tube is slowed down, allowing for comprehensive polishing of the yarn tube. Then, the lifting cylinder 5 is activated, controlling the folding... The curved arm 4 descends, causing the fixed seat 6, movable seat 7, and abrasive belt 22 to descend as well. Once the bottom surface of the abrasive belt 22 contacts the yarn tube surface, the lifting cylinder 5 continues to control its descent, causing the yarn tube to bulge the bottom surface of the abrasive belt 22. During this bulging process, the driven wheels 21 on both sides move inward synchronously, and the bottom of the rotating frame 20 rotates inward accordingly. As the rotating frame 20 rotates, it bends the spring sheet 23 via the pressure roller 24. The elastic force generated by the bent spring sheet 23 acts in the opposite direction on the abrasive belt 22, causing the bottom surface of the abrasive belt 22 to press tightly against the yarn tube surface and apply pressure to the yarn tube, facilitating subsequent abrasive work. When the pressure roller 24 bends the spring sheet 23, it slides relative to the surface of the bent spring sheet 23, causing the bent spring sheet 23... The lever arm also changes accordingly, compensating for the constantly changing elastic force of the spring plate 23 as the degree of bending changes, thus keeping the force applied to the yarn tube by the bottom surface of the abrasive belt 22 stable. Furthermore, rotating the internal hexagonal adjusting nut 29 can drive the driving bevel gear 30 to rotate, which in turn drives the driven bevel gear 28 and the short shaft 27 to rotate, thereby driving the threaded rod 31 to rotate. When the threaded rod 31 rotates, it causes the support platform 32 to move up and down. When the position of the support platform 32 changes, the fulcrum of the spring plate 23 when bending also changes, thus changing the elastic force generated by the bending of the spring plate 23. This allows for easy adjustment of the pressure applied to the yarn tube by the abrasive belt 22 to adapt to different yarn tubes. Then, the reduction motor 11 is started, and the force is transferred through the reduction motor 1... 1. The main shaft 12 rotates, and the keyway 14 of the spline 13 limits its movement, driving the drum 9 and the drive wheel 10 to rotate. Combined with the action of the two driven wheels 21, this causes the abrasive belt 22 to move at high speed. Simultaneously, the rotation of the main shaft 12 also drives the first chuck 15 to rotate. Utilizing the toothed structure formed by the two sets of interlocking hemispherical protrusions 17 between the first chuck 15 and the second chuck 16, along with the action of the return spring 8, the movable seat 7 and the abrasive belt 22 vibrate rapidly left and right. Combined with the high-speed movement of the abrasive belt 22 itself, this provides rapid and efficient abrasive polishing of the yarn tube surface. Finally, the linear motion module 2 controls the movement of the drive end slide, causing the abrasive belt 22 to translate, completing the all-around abrasive polishing of the yarn tube. After polishing...Simply remove the yarn tube. During the polishing process, start the air pump 44. The dust and debris generated during polishing will be sucked into the dust collection box 43 to prevent dust from falling onto other equipment and causing wear.
