Description

Technical Field

[0001] This invention relates to the field of rubber roller polishing technology, specifically a textile rubber roller polishing device. Background Technology

[0002] As a crucial drafting element in textile machinery, the surface condition of textile rollers directly affects yarn quality, production efficiency, and equipment operational stability. During textile production, the surface of the rollers gradually develops problems such as aging, wear, and uneven roughness due to long-term high-speed friction, fiber entanglement, and chemical corrosion, thus affecting fiber holding and drafting effects. Therefore, regular polishing of the rollers is a vital process for ensuring stable yarn quality and continuous production. The main purpose of this process is to repair surface defects, restore geometric accuracy, optimize surface friction performance, and delay elastic aging, thereby extending the service life of the rollers and improving yarn quality.

[0003] Currently, the polishing of textile rubber rollers typically relies on specialized polishing devices. These devices generally work by bringing the roller to be treated into contact with a high-speed rotating polishing belt, achieving surface cutting and finishing through relative motion. However, existing polishing devices generally suffer from insufficient contact control precision. Specifically, in actual polishing processes, the contact area between the roller and the polishing belt is often fixed, lacking an effective adjustment mechanism. Because different polishing stages (such as rough grinding, fine grinding, and polishing) have different requirements for surface removal and microstructure, the required contact area should also vary to adapt to the control needs of grinding force distribution and heat accumulation. Current equipment struggles to flexibly adjust contact parameters to meet these differentiated needs, resulting in unsatisfactory polishing effects, uneven polishing, localized overheating, and surface damage, ultimately affecting the subsequent performance of the rubber roller. Therefore, there is an urgent need to improve the structure and control methods of existing textile rubber roller polishing devices to enhance their adaptability to complex working conditions and improve polishing quality. Summary of the Invention

[0004] This invention provides a textile rubber roller polishing device, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A textile rubber roller polishing device includes a base, a movable support is slidably mounted on one side of the base, a sanding belt is sleeved on the movable support, and a clamping mechanism and a supporting mechanism.

[0007] A clamping mechanism is provided on the side of the base away from the movable support, for clamping and driving the rubber roller to rotate, the axis of the rubber roller being parallel to the moving trajectory of the movable support;

[0008] The support mechanism includes a guide column slidably connected to the movable bracket. A U-shaped bracket is fixedly connected to one end of the guide column near the rubber roller. A central support roller is rotatably mounted on the U-shaped bracket. The central support roller is used to support the inner side of the sanding belt. Swing arms are rotatably mounted on both sides of the U-shaped bracket. The two swing arms are symmetrically arranged relative to the U-shaped bracket and can rotate synchronously in opposite directions. A side support roller is rotatably mounted at the end of each swing arm. The central support roller and the side support roller alternately abut against the inner side of the sanding belt to change the contact area between the sanding belt and the rubber roller.

[0009] As a preferred embodiment of the present invention, the U-shaped bracket is provided with bearing seats on both sides, and a rotating shaft is rotatably mounted on each bearing seat. One end of the rotating shaft is fixedly connected to the end of the corresponding swing arm, and the other end of the rotating shaft is fixedly connected to a synchronous gear. Two synchronous gears located at the same end of the U-shaped bracket mesh with each other.

[0010] As a preferred embodiment of the present invention, one of the synchronous gears is provided with an angle scale at its end, and the U-shaped bracket is provided with a pointer that cooperates with the angle scale at its end. When the swing arm is tilted toward the rubber roller, the angle scale value indicated by the pointer corresponds to the included angle between the two swing arms.

[0011] As a preferred embodiment of the present invention, the swing arm is provided with an extension rod in the middle, and a fixing plate is provided at the end of the extension rod. A return spring is provided between the two fixing plates located at the same end of the U-shaped bracket.

[0012] As a preferred embodiment of the present invention, the movable support is provided with a drive roller for driving the sanding belt to rotate on the side near the base, the side of the base is provided with a transverse drive assembly for driving the movable support to move, and the movable support is provided with a tension adjustment assembly for tensioning the sanding belt on the side away from the base.

[0013] As a preferred embodiment of the present invention, the tension adjustment assembly includes a sliding sleeve fixed to the side of the movable bracket away from the base, a sliding column slidably connected to the side of the sliding sleeve away from the movable bracket, and one end of the sliding column extending out of the sliding sleeve and fixedly connected to a fixing block, the tension roller being rotatably mounted on the fixing block, the tension roller abutting against the inner side of the sanding belt, a limiting ring for limiting the relative sliding stroke of the sliding column and the sliding sleeve being provided in the middle of the sliding column, and a tension spring being provided inside the sliding sleeve to drive the sliding column to move away from the sliding sleeve.

[0014] As a preferred embodiment of the present invention, a transverse guide screw is threadedly connected to the side of the movable bracket away from the base. The end of the transverse guide screw near the rubber roller is rotatably connected to the U-shaped bracket, and the end of the transverse guide screw away from the rubber roller is rotatably connected to a fixed plate. A rotary drive device for driving the transverse guide screw to rotate is provided in the middle of the fixed plate. The end of the fixed plate is fixedly connected to the end of the guide column. A fixed roller is provided on the side of the fixed plate away from the rubber roller, and the fixed roller abuts against the inner side of the sanding belt.

[0015] As a preferred embodiment of the present invention, the side of the movable bracket is provided with a top rod inclined toward the rubber roller, and the end of the top rod is provided with a top head. When the swing arm is inclined away from the rubber roller and the U-shaped bracket moves away from the rubber roller, the top head abuts against the swing arm and pushes the swing arm to flip toward the rubber roller.

[0016] As a preferred embodiment of the present invention, the clamping mechanism includes fixed brackets disposed at both ends of the base, with clamping heads disposed at the ends of the fixed brackets, and the rubber roller disposed between the two clamping heads.

[0017] The present invention has the following advantages:

[0018] 1. This device achieves flexible adjustment of the contact area between the abrasive belt and the rubber roller through a support mechanism consisting of a central support roller and side support rollers that can swing synchronously in opposite directions. When the two side support rollers abut against the inner side of the abrasive belt, the abrasive belt is supported to form a larger arc-shaped support surface, which can produce an adaptive indentation when in contact with the rubber roller, forming a larger envelope contact surface. This state is suitable for the rough grinding stage, which can significantly improve material removal efficiency, quickly correct large protrusions and shape errors on the surface of the rubber roller, and lay the foundation for subsequent finishing.

[0019] 2. When switching to the working state where the middle support roller abuts against the inner side of the sanding belt, the sanding belt is rigidly supported, and the contact form with the rubber roller changes to line contact. This state is suitable for the fine grinding stage, which can perform high-precision finishing of the surface roughness and roundness of the rubber roller, avoiding uneven grinding or overheating damage caused by excessive contact area, thereby effectively improving the surface quality and dimensional accuracy of the rubber roller.

[0020] 3. This device, through the coordinated design of the swing arm, synchronous gears, angle dial, and return spring, not only achieves stable switching between two grinding states but also monitors changes in the swing arm angle in real time, thereby indirectly controlling the grinding pressure. Operators can precisely adjust the contact pressure according to process requirements, ensuring the controllability and consistency of the grinding process.

[0021] 4. This device can complete both rough grinding and fine grinding processes in a single setup, avoiding positioning errors caused by repeated setups, simplifying the operation process, and significantly improving processing efficiency. Furthermore, the coordinated design of the push rod and swing arm enables automatic reset of the working state, further enhancing the automation level and ease of operation of the equipment.

[0035] The technical solutions of 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.

[0036] In one embodiment, see Figure 1 , Figure 2 , Figure 3 and Figure 4 A textile rubber roller polishing device includes a base 1, which preferably adopts a U-shaped structure design to ensure sufficient structural strength to stably support the functional components while effectively reducing the overall weight of the equipment. The base 1 is positioned along the front-to-back direction. A movable support 2 is slidably mounted on the right side of the base 1. The movable support 2 can reciprocate along the front-to-back direction of the base 1. The main structure of the movable support 2 can be composed of a base plate positioned along the front-to-back direction, L-shaped support rods fixed to the front and rear sides of the base plate, and crossbars connected to the top of the support rods, forming a stable frame structure. An annular abrasive belt 4 is sleeved on the outside of the movable support 2. The movement of the movable support 2 can drive the abrasive belt 4 to move synchronously back and forth, thereby achieving polishing processing of the rubber roller 6 at different axial positions.

[0037] To clamp and drive the rubber roller 6, a clamping mechanism 5 is provided on the left side of the upper surface of the base 1. The clamping mechanism 5 includes a fixed bracket 7 fixed to the front and rear sides of the left end of the base 1. The fixed bracket 7 has a C-shaped structure, and clamping heads 8 are mounted on its upper part and are arranged opposite to each other and can extend and retract in the front-rear direction. The two ends of the rubber roller 6 are respectively clamped and fixed by the two clamping heads 8, thereby achieving reliable clamping. The clamping head 8 integrates a drive unit, which can drive the rubber roller 6 to rotate around its own axis. After clamping, the axis of the rubber roller 6 is also arranged in the front-rear direction and parallel to the movement trajectory of the moving bracket 2, ensuring that the sanding belt 4 can effectively contact the entire working surface of the rubber roller 6.

[0038] The support mechanism 3 includes guide columns 11 disposed on the front and rear sides of the upper end of the movable bracket 2. The guide columns 11 are arranged in a left-right orientation. A U-shaped bracket 13 arranged in a front-back orientation is fixedly connected to the left end of the guide column 11. A central support roller 24 arranged in a front-back orientation is rotatably connected to the left end of the U-shaped bracket 13. Swing arms 25 are rotatably connected to both the upper and lower sides of the U-shaped bracket 13. A side support roller 26 is rotatably connected to the end of the swing arm 25 away from the U-shaped bracket 13. Both the side support roller 26 and the central support roller 24 are disposed inside the sanding belt 4. Through the structural arrangement, the two swing arms 25 are symmetrically arranged with respect to the U-shaped bracket 13 and the two swing arms 25 rotate synchronously in opposite directions. That is to say, the two side support rollers 26 are In the actual working process, the side support rollers 26 and the middle support roller 24 alternately abut against the sanding belt 4. When the two side support rollers 26 abut against the sanding belt 4 at the same time, the sanding belt 4 between the two side support rollers 26 contacts the rubber roller 6. The sanding belt 4 bends adaptively, so that part of the sanding belt 4 can adhere to the surface of the rubber roller 6, increasing the contact area. When the middle support roller 24 abuts against the inner wall of the sanding belt 4, the contact area when the sanding belt 4 contacts the rubber roller 6 is approximately a line or only a small part of the contact area caused by the deformation of the sanding belt 4 itself, which greatly reduces the contact area. In order to ensure this working effect, the axis of the middle support roller 24 and the axis of the rubber roller 6 are at the same horizontal height.

[0039] In one instance of this embodiment, please refer to Figures 7-11Bearing seats 34 are provided at both the front and rear ends of the U-shaped bracket 13, meaning that a total of four bearing seats 34 are provided at the front and rear ends of the upper and lower surfaces of the U-shaped bracket 13. The bearing seats 34 are rotatably connected to rotating shafts 31 arranged in a front-rear orientation. The end of the rotating shaft 31 near the center of the U-shaped bracket 13 is fixedly connected to the end of the swing arm 25, and the end of the rotating shaft 31 away from the center of the U-shaped bracket 13 is fixedly connected to a synchronous gear 30. By placing the synchronous gear 30 on the outside of the swing arm 25, interference with the rotation of the swing arm 25 is avoided. Furthermore, the two synchronous gears 30 located at the same end of the U-shaped bracket 13 are meshed, meaning that the two synchronous gears 30 on the front side of the U-shaped bracket 13 mesh with each other, and the two synchronous gears 30 at the rear end of the U-shaped bracket 13 are also meshed. Through the meshing of the synchronous gears 30, the two swing arms 25 rotate synchronously in opposite directions, thereby realizing the synchronous reverse movement of the two side support rollers 26 on the upper and lower sides of the U-shaped bracket 13.

[0040] To facilitate precise control and perception of the grinding pressure by the operator, an angle scale 33 is provided at the end of one of the synchronous gears 30 located at the upper front side. Correspondingly, a pointer 32 cooperating with the angle scale 33 is fixedly provided at the front end of the U-shaped bracket 13. When the swing arm 25 swings, the value on the angle scale 33 can be read through the pointer 32, which directly corresponds to the included angle between the two swing arms 25. Combined with the return spring 29 connected between the two swing arms 25, the change in this included angle can indirectly reflect the extension length of the return spring 29, thereby calculating the pressure of the sanding belt 4 acting on the surface of the rubber roller 6. This makes the grinding pressure real-time visible and adjustable, and the operator can precisely control the grinding pressure by moving the bracket 2 laterally or the U-shaped bracket 13 left and right.

[0041] At the middle of the swing arm 25, there is also a forward-backward extending rod 27, which is rotatably connected to the swing arm 25. A fixing plate 28 is provided at the end of the extending rod 27, and a return spring 29 is connected between the fixing plates 28 located on the upper and lower swing arms 25. The two ends of the return spring 29 are fixedly connected to the two fixing plates 28 respectively. This return spring 29 provides preload for the swing of the swing arm 25 and also ensures that the swing arm 25 maintains a stable tendency in its two extreme positions: the two side support rollers 26 abutting against the sanding belt 4, or the middle support roller 24 abutting against the sanding belt 4. When the swing arm 25 passes the middle vertical position, the tension of the return spring 29 will cause it to swing quickly to and stabilize at the other extreme position.

[0042] In one instance of this embodiment, please refer to Figure 4 and Figure 5A drive roller 10, arranged in a front-to-back direction, is located below the movable support 2 and abuts against the inner wall of the sanding belt 4. The drive roller 10 integrates a power unit that actively drives the sanding belt 4 to rotate. By setting the rotation directions of the sanding belt 4 and the rubber roller 6 to opposite directions, or by making them have different linear velocities, relative motion can be generated between the sanding belt 4 and the rubber roller 6, thereby achieving sanding. A transverse drive assembly 9 is also provided on the right side of the base 1. This assembly preferably includes a lead screw arranged in a front-to-back direction, which is threadedly connected to the bottom of the movable support 2. The rotation of the lead screw drives the movable support 2 to move back and forth. To improve the smoothness of movement, guide rails can be provided on both sides of the lead screw, and the movable support 2 slides against the base 1 through the guide rails.

[0043] In one instance of this embodiment, please refer to Figure 5 and Figure 6 A tension adjustment assembly 14 is also provided at the upper end of the movable support 2 to maintain the appropriate tension of the sanding belt 4 during operation. The tension adjustment assembly 14 includes sliding sleeves 19 fixed to the front and rear sides of the upper end of the movable support 2. The sliding sleeves 19 are vertically hollow structures, with vertically oriented sliding columns 20 sliding through them. The upper end of the sliding column 20 extends out of the sliding sleeve 19 and is fixedly connected to a fixing block 22. A tension roller 23 is rotatably mounted between the two fixing blocks 22, and the tension roller 23 abuts against the inner wall of the sanding belt 4. A tension spring 18 is provided inside the sliding sleeve 19, which always applies a force that pushes the sliding column 20 upward, thereby providing tension to the sanding belt 4. A limiting ring 21 is also provided on the sliding column 20 to limit the extreme position of the upward sliding of the sliding column 20.

[0044] In one instance of this embodiment, please refer to Figure 4 and Figure 5 The transverse lead screw 12 is threaded to the middle of its upper end. The transverse lead screw 12 is oriented left-right. Its left end is rotatably connected to the middle of the right side of the U-shaped bracket 13. The right end of the transverse lead screw 12 is rotatably connected to a fixing plate 16 oriented front-back. A rotary drive device 17, using a servo motor, is located in the middle of the fixing plate 16. The rotary drive device 17 drives the transverse lead screw 12 to rotate, thus causing the U-shaped bracket 13 to move left-right. The front and rear ends of the fixing plate 16 are fixedly connected to guide posts 11. A fixing roller 15 is located on the right side of the fixing plate 16. The fixing roller 15 abuts against the inner wall of the sanding belt 4, and its function is to keep the sanding belt 4 open and stable in position as the U-shaped bracket 13 moves left-right.

[0045] In one instance of this embodiment, please refer to Figure 5 , Figure 9 and Figure 10The upper surface of the movable support 2 is also provided with top rods 35 on both the front and rear sides. The top rods 35 are inclined to the upper left and the end of them is equipped with a top head 36. The top rods 35 are used to contact the right-inclined swing arm 25 when the U-shaped support 13 moves to the right limit position and push it to flip to the left, so that the device automatically switches from the operation of the middle support roller 24 in the fine grinding state to the operation of the side support roller 26 in the coarse grinding state, which facilitates the processing cycle of the next rubber roller 6.

[0046] The working process of this device mainly includes initial preparation, rough grinding, state switching, fine grinding, and state reset.

[0047] 1. In the initial preparation stage, the operator first installs the rubber roller 6 to be processed between the two clamping heads 8 of the clamping mechanism 5 and tightens it. Then, the two swing arms 25 are adjusted to the initial state of tilting to the left. At this time, the two side support rollers 26 abut against the sanding belt 4 from the inside, supporting the sanding belt 4 to form a larger arc-shaped contact surface. The drive roller 10 and the drive unit in the clamping mechanism 5 are started to make the sanding belt 4 and the rubber roller 6 rotate in the predetermined direction.

[0048] 2. In the rough grinding stage, the rotary drive device 17 is activated, driving the U-shaped support 13 to move to the left via the transverse lead screw 12. This causes the area of ​​the sanding belt 4, supported by the side support roller 26, to contact the surface of the rubber roller 6 and apply a certain pressure. Because the sanding belt 4 has a large flexible contact surface in this state, it can better conform to the surface of the rubber roller 6, thereby efficiently removing large protrusions and shape errors on the surface of the rubber roller 6, completing the initial shaping and rough grinding of the rubber roller 6. During this process, the angle change of the swing arm 25 can be monitored in real time via the angle scale 33 and the pointer 32, indirectly controlling the grinding pressure.

[0049] 3. During the state switching stage, after rough grinding is completed and the surface shape of the rubber roller 6 is basically regular, the U-shaped bracket 13 is moved to the right by the transverse lead screw 12, causing the sanding belt 4 to disengage from the rubber roller 6. This allows the tension spring 18 to push the tension roller 23 to further tighten the sanding belt 4 upwards. Then, the limiting ring 21 on the tension adjustment assembly 14 is adjusted to restrict the sliding column 20 from continuing to slide upwards, and the sliding column 20 stops sliding relative to each other. Subsequently, the U-shaped bracket 13 is moved to the left again. When the side support roller 26 contacts and presses against the inner wall of the sanding belt 4 again, the tension force inside the sanding belt 4 increases because the tension roller 23 is locked. This forces the two side support rollers 26 to overcome the tension of the return spring 29 and separate from each other. When the swing arm 25 passes the vertical state (i.e., the 'dead point' position), the tension of the return spring 29 will cause it to swing quickly and stabilize at the extreme position tilted to the right. At this point, the sanding belt 4 has switched to a state where it is supported from the inside by the central support roller 24. If the swing arm 25 cannot be adjusted to a rightward tilt state by the pressure of the sanding belt 4 itself, the swing arm 25 can be manually rotated to the right after the swing arm 25 moves to its limit, that is, after the middle support roller 24 has abutted against the sanding belt 4, thereby realizing the angle adjustment of the swing arm 25.

[0050] 4. In the fine grinding stage, the limiting ring 21 is opened, allowing the sliding column 20 to move freely up and down. The U-shaped bracket 13 is then precisely moved to the left by the transverse lead screw 12, so that the area of ​​the sanding belt 4 supported by the central support roller 24 comes into contact with the rubber roller 6. At this time, due to the rigid support of the central support roller 24, the contact between the sanding belt 4 and the rubber roller 6 is approximately a line, which can finely adjust the surface roughness and roundness of the rubber roller 6, completing the fine grinding process.

[0051] 5. State Reset Stage: After grinding one rubber roller 6, the finished rubber roller 6 is removed. The U-shaped bracket 13 is moved to the right to its limit position by the transverse lead screw 12. During this process, the rightward tilting swing arm 25 will contact the top head 36 at the end of the top rod 35 fixed on the moving bracket 2. As the U-shaped bracket 13 continues to move to the right, the top head 36 pushes the swing arm 25 to flip to the left, so that after passing the vertical state, it automatically returns to the initial leftward tilting state under the action of the reset spring 29, preparing for the next processing.

[0052] This invention provides a textile rubber roller polishing device. By setting up a support mechanism 3 consisting of a central support roller 24 and side support rollers 26 that can swing synchronously in opposite directions, the contact area between the abrasive belt 4 and the rubber roller 6 is flexibly adjusted. When the two side support rollers 26 abut against the inner side of the abrasive belt 4, the abrasive belt 4 can generate an adaptive indentation upon contact with the rubber roller 6, forming a larger envelope contact surface, suitable for the rough polishing stage. This significantly improves material removal efficiency and quickly corrects shape errors of the rubber roller 6. When switching to the central support roller 24 abutting against the inner side of the abrasive belt 4, the abrasive belt 4 is rigidly supported, and the contact form with the rubber roller 6 changes to line contact, suitable for the fine polishing stage. This allows for high-precision finishing of the surface roughness and roundness of the rubber roller 6. Therefore, this device can complete both rough and fine polishing processes on the same rubber roller 6 in a single setup by simply switching polishing modes. This not only improves processing efficiency and avoids positioning errors caused by repeated setups, but also significantly improves the overall polishing quality and surface consistency of the rubber roller 6 by precisely controlling the contact shape and pressure.

[0053] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
