Description

Technical Field

[0001] The invention relates to the field of textile equipment, in particular to a traction roller grinding device and a sizing machine. Background Art

[0002] The traction roller on the sizing machine is an important part of the sizing machine head. The roller body of the traction roller is covered with rubber. After the yarn passes through the traction roller, it is wound into a weaving shaft. Since the roller body span of the traction roller is large, usually the length of the traction roller is more than 3 meters. Under the action of its own weight and winding tension, it will produce flexible deformation. In order to ensure the fit between the traction roller and the pressure roller that matches it, the outer contour of the rubber roller is high in the middle and low at both ends (similar to an olive shape). According to the specific length of the traction roller, the diameter in the middle of the traction roller is 0.4 to 1.0 mm larger than the diameter at both ends.

[0003] During production and use, the rubber of the traction roller will wear out, resulting in the phenomenon of partial looseness of the yarn and the need to grind the roller. However, due to the shape limitation of the traction roller, most of them use the hand-held abrasive belt grinding method, which is prone to danger, and the grinding amount is completely determined by the feel, and the accuracy cannot be guaranteed.

[0027] In the related art, the traction roller on the sizing machine is an important part on the locomotive of the sizing machine. The roller body of the traction roller is covered with rubber. After the yarn passes through the traction roller, it is wound into a weaving shaft. Since the roller body span of the traction roller is large, usually, the length of the traction roller is more than 3 meters. Under the action of its own weight and winding tension, it will produce flexible deformation. In order to ensure the fit between the traction roller and the pressure roller matched with it, the outer contour of the rubber roller is a shape with a high middle and low ends (similar to an olive shape). According to the specific length of the traction roller, the middle diameter of the traction roller is 0.4 to 1.0 mm larger than the diameter at both ends.

[0028] During production and use, the rubber of the traction roller will wear out, resulting in the phenomenon of partial looseness of the yarn and the need to grind the roller. However, due to the shape limitation of the traction roller, most of them use the hand-held abrasive belt grinding method, which is prone to danger, and the grinding amount is completely determined by the feel, and the accuracy cannot be guaranteed.

[0029] like Figures 1 to 5As shown, in order to solve the above technical problems, an embodiment of the present application provides a traction roller grinding device including a first driving member, a guide member, an adjusting member, a sliding member 10, a grinding member and a second driving member, wherein the first driving member is detachably connected to the traction roller 1, and the first driving member is used to drive the traction roller 1 to rotate; the guide member is connected to the adjusting member, and the adjusting member can adjust the distance between the guide member and the axis of the traction roller 1, and the guide member has a guiding end face, and the guiding end face is located at the end of the guide member away from the traction roller 1, and the extension direction of the generatrix close to the guiding end face on the target contour of the traction roller 1 is parallel to the extension direction of the guiding end face; the sliding member 10 abuts against the guiding end face; the grinding member is connected to the sliding member 10, and the grinding member has a grinding end face, and the grinding end face is used to abut against the outer surface of the traction roller 1; the second driving member is connected to the sliding member 10, and the second driving member can drive the sliding member 10 to move along the guiding end face.

[0030] In these embodiments, the invention provides a device for grinding the traction roller 1 of a sizing machine, aiming to solve the problems of low efficiency, poor precision and safety in the existing grinding method with a hand-held abrasive belt 11. Among them, the first driving member is responsible for driving the traction roller 1 to rotate, so that during the grinding process, the traction roller 1 can rotate at a certain speed, so that the entire surface and the grinding end face below can be evenly ground.

[0031] Guide and adjustment: By using the guide and adjustment together, the traction roller 1 of different sizes and shapes can be adjusted to a suitable position to ensure accuracy and consistency during the grinding process. The adjustment is specially designed to adapt to the characteristics of the traction roller 1, which is high in the middle and low at both ends, to ensure that the grinding end surface always works according to the target profile of the traction roller 1, so as to finally form the target profile on the surface of the traction roller 1. Among them, the adjustment can control the feed amount of each grinding.

[0032] Sliding member 10: The sliding member 10 moves along the guide member and maintains contact with the guide member, which helps to control the movement trajectory of the grinding member (such as a grinding wheel), thereby improving the grinding quality and controlling the grinding accuracy.

[0033] Grinding piece: The grinding end surface of the grinding piece directly acts on the traction roller 1 to perform the actual grinding or trimming operation. Optionally, the grinding end surface of the grinding piece is replaceable so that different abrasives can be replaced as needed to repair different degrees of wear and adjust the grinding efficiency.

[0034] For example, when the grinding amount of the traction roller 1 to be ground is large, the grinding end surface can be set to coarse grinding for rapid grinding, and then the grinding end surface can be replaced with fine grinding for fine grinding. Obviously, the whole grinding process takes less time and is more efficient.

[0035] Second driving member: The second driving member provides power for the sliding member 10 , so that the sliding member 10 can move smoothly on the guide member, thereby driving the grinding member to perform grinding operations uniformly along the length direction of the traction roller 1 .

[0036] Therefore, by controlling the second driving member to drive the sliding member 10 to move along the guide end face of the guide member, so as to control the moving path of the grinding end face and the generatrix matching of the target contour of the traction roller 1, and by controlling the spacing between the axis of the guide member and the traction roller 1 through the adjusting member, the feed amount of a single grinding can be controlled. Among them, the first driving member drives the traction roller 1 to rotate, so as to realize the relative rotation of the traction roller 1 and the grinding end face to produce a grinding action, and the grinding of the entire outer surface of the traction roller 1 is completed by using the radial movement and axial feed of the grinding end face on the traction roller 1. Obviously, this traction roller grinding device can replace traditional manual operations through mechanized means, which not only improves work efficiency, but also significantly improves grinding accuracy, while reducing potential risks caused by human factors. In addition, such a system is also easier to maintain and manage, which has a positive effect on extending the service life of the equipment.

[0037] In some embodiments, the adjusting member includes a supporting portion and an adjusting portion 13, the number of the adjusting portions 13 is multiple, the supporting portion is connected to the guide member through the adjusting portion 13, the multiple adjusting portions 13 are arranged at intervals along the axial direction of the traction roller 1, and the guide end face has multiple guide sections in the axial direction of the traction roller, and the adjusting portion 13 can adjust the distance between the corresponding guide section and the axis of the traction roller 1.

[0038] In some embodiments, the design of the adjustment member is further refined to adapt to the special shape requirements of the traction roller 1. Specifically, the adjustment member is composed of a support portion and a plurality of adjustment portions 13. Such a design enables the grinding device to more flexibly adjust the relative position between the guide end surface and the traction roller 1, ensuring that the correct geometric relationship can be maintained during the grinding process, especially for the non-linear surface of the traction roller 1, such as the middle diameter is larger than the two ends. Among them, the support portion serves as the basic structure of the entire adjustment assembly, and the support portion provides an installation point for the adjustment portion 13, and is usually fixed in a relatively stable position, such as a frame or other solid support.

[0039] The number of the adjusting parts 13 can be two or more, distributed along the axial direction of the traction roller 1. Each adjusting part 13 is responsible for fine-tuning the position of the guide member in the corresponding area relative to the traction roller 1. By independently controlling each adjusting part 13, the guide end surface on the guide member can accurately match the contour change of the traction roller 1. For example, in the center part of the traction roller 1, the adjusting part 13 may need to push the guide member further away from the axis of the traction roller 1; and near the two ends, the spacing is reduced accordingly, so that it can be ensured that the grinding end surface always fits closely to the outer surface of the traction roller 1 for work.

[0040] A plurality of guide segments are preset on the guide end surface, and these segments are arranged according to a certain rule (usually along the length direction of the traction roller 1). Each guide segment corresponds to one or a group of adjustment parts 13, allowing the spacing of different parts to be adjusted separately. Such a design helps to achieve more accurate positioning, especially when processing workpieces with complex curvature changes.

[0041] For example, the generatrix of the traction roller 1 is in an arc shape, and the above-mentioned arrangement enables the guide end surface to form an arc shape that matches the generatrix.

[0042] In summary, the adjustment mechanism achieves good tracking of the overall shape of the traction roller 1 by operating multiple independently controllable points, thereby ensuring high precision and consistency throughout the grinding process. In addition, this segmented adjustment method also provides great flexibility for dealing with traction rollers 1 of different types, sizes, and even different degrees of wear.

[0043] It should be noted that, in order to ensure the continuity of the guide end surface, the guide end is provided in an integrated manner, and is merely a portion artificially divided on the guide end surface.

[0044] Exemplarily, the adjusting portion 13 includes an adjusting bolt, and the guide member is connected to the supporting portion via the adjusting bolt. The adjusting bolt is rotated to adjust the gap between the guide member and the supporting portion. Accordingly, the distance between the guide end face and the axis of the traction roller 1 can be adjusted.

[0045] In some embodiments, the second driving member includes a screw rod 9, a slider 8, a mounting seat 6, a first driving part and a second driving part 14. The mounting seat 6 is connected to the support part. The mounting seat 6 has a slide groove, which extends along the first preset direction. The first preset direction is perpendicular to the axis of the traction roller 1. The slider 8 is slidably installed in the slide groove. The first driving part is connected to the slider 8. The first driving part is used to drive the slider 8 to move along the first preset direction. The screw rod 9 is connected to the slider 8 through the second driving part 14. The screw rod 9 extends along the axis of the traction roller 1. The second driving part 14 is used to rotate the screw rod 9. The sliding member 10 has a threaded hole. The hole wall of the threaded hole is threadedly connected to the screw rod 9, and there is surface contact between the sliding member 10 and the guide end face.

[0046] In these embodiments, the second driving member is designed to achieve accurate movement of the sliding member 10 along the guide end surface. Such a design can ensure high-precision control during the grinding process while maintaining the stability and operability of the system.

[0047] Specifically, the screw rod 9 is a long rod with spiral patterns, and the screw rod 9 is extended along the axis of the traction roller 1. When the screw rod 9 rotates, the sliding member 10 can be driven to move axially along the screw rod 9 by interacting with the threaded hole on the sliding member 10.

[0048] The slider 8 is assembled in the slide groove in the mounting seat 6 and can slide freely therein. The direction of the slide groove is perpendicular to the axis of the traction roller 1 (i.e., the first preset direction), which provides a stable base for the slider 10, so that it can be fine-tuned in the direction perpendicular to the axis of the traction roller 1, thereby adjusting the gap between the guide end surface and the axis of the traction roller 1.

[0049] The mounting seat 6 is fixedly connected to the supporting part, and a slide groove is provided on the mounting seat 6 to accommodate and guide the movement of the slider 8. The mounting seat 6 plays the role of supporting the entire drive assembly and ensures that the relative positions between the assemblies remain unchanged.

[0050] The first driving part is used to drive the slide block 8 to move in the first preset direction in the slide groove. This lateral movement can help adjust the position of the grinding device relative to the side of the traction roller 1 to better meet the grinding requirements of parts with different diameters.

[0051] The second driving unit 14 is responsible for driving the screw 9 to rotate. The rotational motion of the screw 9 is converted into the linear motion of the sliding member 10 along the axis direction of the traction roller 1, thereby achieving full coverage grinding in the length direction of the traction roller 1. Exemplarily, the second driving unit 14 includes a driving motor, and the main shaft of the driving motor is coaxially connected to the screw 9.

[0052] The sliding member 10 has a threaded hole, which cooperates with the external thread of the screw rod 9 to form a spiral transmission pair. As the screw rod 9 rotates, the sliding member 10 will move forward or backward along the screw rod 9. In addition, the sliding member 10 is also designed to maintain a surface contact state with the guide end surface of the guide member to ensure good positioning and stability during the grinding process.

[0053] Through the above structure, the second driving member not only realizes the controllable movement of the sliding member 10 in two dimensions, including the first preset direction perpendicular to the axis of the traction roller 1, but also the direction parallel to the axis of the traction roller 1, that is, the sliding member 10 can move in the radial and axial directions of the traction roller 1, but also improves the accuracy and efficiency of the grinding work through the precise mechanical linkage mechanism. This method ensures the consistency of the grinding quality even when processing the traction roller 1 with a complex shape.

[0054] In some embodiments, the number of mounting seats 6 is a pair, and the pair of mounting seats 6 are respectively located at two ends of the screw rod 9, and the two ends of the screw rod 9 are rotatably connected to the sliders 8 assembled in the corresponding mounting seats 6.

[0055] In these embodiments, in order to improve the stability and symmetry of the system, the mounting seats 6 are designed as a pair and are respectively located at both ends of the screw rod 9. Such a structure can provide better support and more uniform force distribution, thereby ensuring the stability and accuracy of the sliding member 10 during movement.

[0056] Specifically, two mounting seats 6 are respectively arranged at the two ends of the screw rod 9. This layout not only enhances the rigidity of the entire drive assembly, but also ensures that the screw rod 9 can be well supported over the entire length.

[0057] Each mounting seat 6 is provided with a slide groove inside, and the slide grooves extend along a first preset direction (a direction perpendicular to the axis of the traction roller 1). The slide groove is used to accommodate the slider 8 and allow the slider 8 to slide freely therein, so as to facilitate lateral position adjustment.

[0058] A slide block 8 is mounted in the slide groove in each mounting seat 6. These slide blocks 8 can slide along the slide groove, and they are each connected to the first driving part, and their positions can be adjusted by the operation of the first driving part. The design of the slide block 8 enables the stability of the grinding device to be maintained even when an irregular surface is encountered during the grinding process.

[0059] Both ends of the screw rod 9 are connected to the slider 8 through bearings or other suitable rotational connection methods. This means that when the second driving part 14 rotates the screw rod 9, the screw rod 9 can rotate freely in the slider 8, while driving the sliding member 10 in the threaded hole to move axially along the screw rod 9. This design ensures the smooth operation of the screw rod 9 and reduces the wear caused by friction.

[0060] As mentioned above, the sliding member 10 has a threaded hole that matches the screw 9. As the screw 9 rotates, the sliding member 10 can move forward or backward on the screw 9 to achieve movement along the axis of the traction roller 1. At the same time, the sliding member 10 maintains surface contact with the guide end surface of the guide member to maintain the correct grinding angle and pressure.

[0061] Obviously, by designing the mounting seat 6 as a pair and placing it at both ends of the screw rod 9, the system not only improves the stability of the overall structure, but also optimizes the consistency and accuracy of the grinding operation. Such a design is particularly suitable for application scenarios that require high-precision control, such as the grinding of the sizing machine traction roller 1.

[0062] In some embodiments, the first driving unit includes a telescopic spring 7, one end of the telescopic spring 7 is connected to the mounting seat 6, and the other end is connected to the slider 8. The telescopic spring 7 is configured to apply a driving force to the slider 8 to move one end of the slide groove close to the traction roller 1.

[0063] In these embodiments, the first driving part includes a telescopic spring 7 to provide a simple and effective mechanism, so that the slider 8 can move along the slide groove and maintain a certain pressure to ensure good contact between the slider 10 and the traction roller 1.

[0064] Specifically, the first driving part is an element with elastic properties, which can be compressed or stretched and can return to its original length after the external force is removed. In this application scenario, one end of the telescopic spring 7 is fixedly connected to the mounting seat 6, and the other end is connected to the slider 8.

[0065] The function of the telescopic spring 7 is to apply a force to the slider 8 in the direction of the traction roller 1 (i.e., the end of the slideway close to the traction roller 1). This means that when there is no other external force, the telescopic spring 7 will try to push the slider 8 toward the traction roller 1, thereby ensuring that the grinding part (such as a grinding wheel) can fit closely on the surface of the traction roller 1 to work. This design helps to compensate for changes in the surface profile of the traction roller 1, ensuring good contact and uniform pressure distribution throughout the grinding process.

[0066] Since the telescopic spring 7 is elastic, it can automatically adjust the position of the slider 8 according to the guide end surface (i.e., the actual shape of the surface of the traction roller 1). When encountering an area where the distance between the guide end surface and the axis of the traction roller 1 is large, the telescopic spring 7 will be further compressed; while in a place where the distance between the guide end surface and the axis of the traction roller 1 is small, the stored energy will be partially released. In this way, adaptive adjustment of the grinding force at different positions is achieved, avoiding the need for frequent manual adjustment.

[0067] Obviously, by introducing the telescopic spring 7 as the core component of the first driving part, the grinding device not only simplifies the mechanical structure, but also enhances the responsiveness and reliability of the system. In particular, for workpieces with a certain curvature change that need to be processed, such a design can effectively improve the consistency and quality of the grinding effect.

[0068] Exemplarily, a mounting plate is provided at the open end of the slide slot, and both ends of the telescopic spring 7 are respectively connected to the mounting plate and one end of the slider 8 close to the mounting plate, and the telescopic spring 7 is in a compressed state.

[0069] In some embodiments, the supporting portion is a square shaft 4, the mounting seat 6 has a square hole and a first locking threaded hole, the square shaft 4 is inserted into the square hole, the first locking threaded hole is connected to the square hole, and the hole wall of the first locking threaded hole is threadedly connected with a first locking bolt; wherein, the axis of the square shaft 4 and the axis of the traction roller 1 are located in the same plane, and the axis of the square shaft 4 and the axis of the traction roller 1 are arranged in parallel.

[0070] In these embodiments, the support portion (square shaft 4) serves as the base of the entire adjustment assembly. The square shaft 4 provides a stable support, and its shape (square cross section) helps prevent rotation, thereby maintaining a fixed position.

[0071] The mounting seat 6 has a square hole for passing the square shaft 4. Since the square hole and the square shaft 4 are both square cross-sections, this can prevent the square shaft 4 from rotating relative to the mounting seat 6, thereby ensuring the stability of the position.

[0072] The first locking threaded hole is connected to the square hole, allowing the first locking bolt to pass through and be screwed in. When the first locking bolt is tightened, it will press the square shaft 4, generating enough friction to fix the position of the square shaft 4 to prevent it from moving or loosening during use.

[0073] By screwing into the first locking threaded hole, the first locking bolt can firmly lock the square shaft 4 in the mounting seat 6. This locking mechanism is not only simple and easy to use, but also very reliable, and can be easily released when adjustment is required, and then re-locked to a new position.

[0074] The axis of the square shaft 4 is in the same plane as the axis of the traction roller 1, which means that the two are arranged in parallel on the same horizontal plane. Such a layout ensures that the adjustment member and all subsequent components (including guide members, sliding members 10, etc.) can be adjusted and moved in the correct direction to accurately match the contour of the traction roller 1. The parallel relationship between the two axes is essential to maintain uniformity and consistency during the grinding process. By ensuring that all movements occur in a direction parallel to the axis of the traction roller 1, unnecessary deviation or tilting can be effectively avoided, thereby improving the grinding quality. This design combines a stable mechanical locking mechanism with flexible adjustment capabilities, allowing the grinding device to perform well when handling traction rollers 1 of different sizes and shapes.

[0075] At the same time, the design of the square shaft 4 increases the rigidity of the system, reduces the displacement that may be caused by vibration or other external forces, and further improves the accuracy and reliability of the grinding operation.

[0076] It should be noted that the above arrangement enables the mounting seat 6 to move along the axis of the square shaft 4, and thus the screw rod 9 with a matching length can be replaced according to the different lengths of the traction rollers 1.

[0077] In some embodiments, the traction roller grinding device further includes a supporting member and a locking member, the supporting member is rotatably connected to the square shaft 4 , the locking member is connected to the square shaft 4 , and the locking member is used to lock the position of the square shaft 4 .

[0078] In these embodiments, the support is rotatably connected to the square shaft 4, which means that the square shaft 4 can rotate in the support. This design allows the square shaft 4 to be angularly adjusted when necessary so that the traction roller 1 is located in the symmetry plane of the guide end surface.

[0079] The locking member is directly connected to the square shaft 4 and is used to lock the square shaft 4 after it is rotated and adjusted to the desired position. This ensures that the square shaft 4 remains stationary during the grinding process, thereby ensuring the consistency and accuracy of the grinding operation. The locking member may take a variety of forms, such as a locking nut, a clamping device, etc. By tightening or activating the locking member, the friction between the square shaft 4 and the support member can be increased, so that it is firmly fixed in the current position.

[0080] Combined with the above structure, the whole system works as follows: First, the square shaft 4 is passed through the square hole of the mounting seat 6 and initially fixed by the first locking bolt. At this time, the position of the square shaft 4 can be fine-tuned according to actual needs.

[0081] If the angle or position of the square shaft 4 needs to be adjusted, the first locking bolt can be loosened, and then the adjustment is performed by rotating or translating the square shaft 4. Due to the presence of the support member, the square shaft 4 can rotate and translate freely within a certain range.

[0082] When the square shaft 4 is adjusted to the correct position, a locking member (such as a locking nut) is used to fix the square shaft 4. At the same time, the first locking bolt is tightened again, and the double locking mechanism ensures that the square shaft 4 will not be displaced due to external force.

[0083] Once the square shaft 4 is firmly locked, the grinding operation can begin. The grinding piece will move along the surface of the traction roller 1, while the sliding piece 10 and the guide piece ensure that the grinding process is carried out according to the contour of the traction roller 1 according to the control of the preset path and the adjustment piece.

[0084] Obviously, such a design not only provides flexible adjustment capabilities, but also ensures the stability of the system through multiple locking mechanisms. This is particularly useful for processing traction rollers 1 with complex shapes, and can improve the grinding efficiency and quality.

[0085] In some embodiments, the support member includes a bracket 3 and a rotating seat 5, the bracket 3 has a rotating hole, the rotating seat 5 can be rotatably assembled in the rotating hole, and the rotating seat 5 is connected to the square shaft 4; The locking member includes a second locking bolt, the bracket 3 has a second locking threaded hole, the second locking threaded hole is communicated with the rotating hole, and the second locking bolt is threadedly connected to the second locking threaded hole.

[0086] In these embodiments, the support 3 is used as the basis of the entire supporting structure, and the support 3 is fixed on a frame or other stable bases. It has a rotation hole for installing a rotating seat 5.

[0087] The rotating seat 5 is rotatably mounted in the rotating hole of the bracket 3. The rotating seat 5 is connected to the square shaft 4 so that the square shaft 4 can rotate freely around the central axis of the rotating hole. This design allows the square shaft 4 and its components (such as guides, adjustment parts, etc.) to be adjusted in angle as needed.

[0088] The second locking bolt is screwed in through the second locking threaded hole, which is connected to the rotating hole. When the second locking bolt is tightened, it will press the rotating seat 5, increase the friction between the rotating seat 5 and the bracket 3, thereby locking the position of the rotating seat 5 and preventing it from continuing to rotate. The second locking threaded hole is set on the bracket 3 and is connected to the rotating hole. This provides a fixed installation position for the second locking bolt and ensures the locking effect.

[0089] For ease of understanding, first, the rotating seat 5 is installed in the rotating hole of the bracket 3, and then the square shaft 4 is fixed to the rotating seat 5. At this time, the square shaft 4 can rotate freely in the rotating hole together with the rotating seat 5.

[0090] According to the specific shape and grinding requirements of the traction roller 1, the operator can adjust the angle of the square shaft 4 by manually rotating the rotating seat 5. Since the rotating seat 5 can rotate freely in the rotating hole, the multi-angle fine adjustment of the square shaft 4 can be achieved.

[0091] Once the square shaft 4 is adjusted to a suitable position, the second locking bolt can be passed through the second locking threaded hole and tightened. The tightened second locking bolt will apply pressure to the rotating seat 5, so that the rotating seat 5 is tightly pressed against the bracket 3, thereby preventing it from continuing to rotate. In this way, the position of the rotating seat 5 and the square shaft 4 is locked.

[0092] After the square shaft 4 is firmly locked, the grinding operation can begin. The sliding member 10 and the grinding member will move along the length direction of the traction roller 1 under the action of the screw 9, while maintaining close contact with the surface of the traction roller 1 to ensure uniform and accurate grinding.

[0093] Obviously, the locking mechanism of the second locking bolt can effectively prevent the square shaft 4 from being displaced unnecessarily during the grinding process, thereby ensuring the grinding accuracy. In addition, the structure provided by this embodiment is easy to disassemble and assemble, and is convenient for daily maintenance and inspection.

[0094] In some embodiments, the guide member is a guide rail 12 , and one end of the guide rail 12 away from the traction roller 1 has a guiding end surface.

[0095] In these embodiments, the guide member is designed as a guide rail 12, and one end thereof away from the traction roller 1 has a guide end surface. Such a design helps to ensure that the sliding member 10 moves along a predetermined path and maintains correct contact with the surface of the traction roller 1.

[0096] Specifically, the guide rail 12 is a linear motion component used to guide the movement of the sliding member 10. It is usually made of hard materials, such as steel or aluminum alloy, to ensure wear resistance and stability in long-term use. The design of the guide rail 12 must be able to withstand the force generated during the grinding process, and it needs to have sufficient rigidity to ensure that the sliding member 10 will not deviate when moving. In addition, the guide rail 12 is set in a plate shape so that it has the ability to move elastic deformation, that is, it can achieve the function of adjusting the extension direction of the guide end surface.

[0097] The guide end surface is located at the end of the guide rail 12 away from the traction roller 1. The shape and position of the guide end surface are designed to ensure that the sliding member 10 always maintains the correct posture and direction during the movement. The specific shape of the guide end surface can be a plane, a curved surface or other specific geometric shapes, which depends on the profile of the traction roller 1 and the required grinding accuracy.

[0098] For example, for an olive-shaped traction roller 1 that is high in the middle and low at both ends, the guide end surface may be designed with a corresponding arc so that the sliding member 10 can follow the contour of the traction roller 1 for grinding.

[0099] For ease of understanding, the working principle is provided as follows: The guide rail 12 is connected to the support part through an adjusting piece, and the position of the guide rail 12 is adjusted so that its guiding end surface matches the contour of the traction roller 1 .

[0100] Use a locking member (such as a second locking bolt) to lock the position of the square shaft 4 and other related components to ensure that the entire device is stable and immobile.

[0101] The slide 10 is in contact with the guide end surface of the guide rail 12 , which can provide a stable reference surface when the slide 10 moves along the screw 9 .

[0102] The grinding member (such as a grinding wheel) on the sliding member 10 contacts the surface of the traction roller 1 through the grinding end surface to perform the grinding operation.

[0103] When the first driving member drives the traction roller 1 to rotate, the second driving member (screw 9 and driving motor) moves the sliding member 10 along the length direction of the traction roller 1. During the movement, the sliding member 10 relies on the guide end surface of the guide rail 12 to maintain a correct posture, ensuring that the grinding member always fits the surface of the traction roller 1 to achieve a uniform grinding effect.

[0104] Obviously, the guide rail 12 provides an accurate linear motion path, so that the slide 10 can move smoothly along the preset track. The design of the guide end surface helps to maintain the correct contact between the slide 10 and the surface of the traction roller 1, thereby improving the consistency and quality of the grinding.

[0105] In some embodiments, the grinding piece is a grinding belt, both ends of which are respectively connected to the sliding piece 10, the grinding belt forms a curved section 2, the guide piece and the traction roller 1 are both located between the two ends of the grinding belt, and the inner side of the curved section 2 abuts against the outer surface of the traction roller 1, and the inner side of the curved section 2 has a grinding end surface.

[0106] In these embodiments, the grinding member is in the form of a grinding belt, which is different from a conventional fixed grinding wheel or sandpaper. The design of the grinding belt can better adapt to the special shape of the traction roller 1 and provide a more uniform and continuous grinding effect.

[0107] Specifically, the grinding belt is a long strip grinding tool made of flexible material, and its surface is covered with abrasive particles (such as aluminum oxide, silicon carbide, etc.). The grinding belt can be a single-layer or multi-layer structure to meet different grinding needs. The two ends of the grinding belt are respectively connected to the sliding member 10 to form a closed loop or semi-closed loop structure. This design allows the grinding belt to move along the length direction of the traction roller 1 under the drive of the sliding member 10.

[0108] Since the grinding belt is flexible, it can bend naturally and fit the outer surface of the traction roller 1. The inner side of the curved section 2 is the grinding end surface, which directly contacts the traction roller 1 for grinding. The design of the curved section 2 can be adjusted according to the contour of the traction roller 1 to ensure that the grinding belt can closely fit the olive-shaped surface of the traction roller 1, which is high in the middle and low at both ends, so as to achieve uniform grinding.

[0109] The guide rail 12 not only guides the movement of the sliding member 10, but also supports and positions the grinding belt. The guide rail 12 can ensure that the grinding belt maintains the correct posture and pressure distribution during the movement. The guide rail 12 and the traction roller 1 are located between the two ends of the grinding belt, thus forming a stable grinding area, in which the curved section 2 of the grinding belt is close to the surface of the traction roller 1.

[0110] It should be noted that the two ends of the grinding belt are fixed to the sliding member 10 to ensure that the grinding belt is tensioned and has no slack. Adjust the guide rail 12 so that its guide end face matches the contour of the traction roller 1, and use the locking member to lock the position of all related components. Start the first drive member to rotate the traction roller 1. The second drive member (screw 9 and drive motor) starts to work, pushing the sliding member 10 to move along the axial direction of the traction roller 1. Driven by the sliding member 10, the grinding belt moves along the length direction of the traction roller 1, and at the same time, the inner side (grinding end face) of the curved section 2 is close to the outer surface of the traction roller 1 for grinding. As the sliding member 10 moves, the curved section 2 of the grinding belt constantly changes its position and always maintains good contact with the surface of the traction roller 1.

[0111] Due to the flexible nature of the grinding belt, it can adapt well to the profile changes of the traction roller 1, ensuring that the entire surface can be evenly ground. The slide 10 is guided by the guide rail 12 to ensure the correct posture and pressure distribution of the grinding belt, thereby improving the grinding quality and efficiency.

[0112] Furthermore, since the grinding belt can completely wrap the surface of the traction roller 1, a more uniform grinding effect can be achieved, reducing the problem of uneven local wear.

[0113] It should be noted that during the grinding process, one side of the sanding belt 11 is subjected to force, and the sanding belt 11 has a loose edge and a tight edge. The tight edge of the sanding belt 11 is always in a tensioned state. As the gap between the guide end face and the axis of the traction roller 1 changes, the length of the tight edge changes accordingly, realizing the change in the grinding amount, and finally achieving the target contour of the traction roller 1.

[0114] In some embodiments, the present application further provides a sizing machine, which includes a traction roller 1 driving member and a traction roller grinding device as described in any of the above embodiments, wherein the first driving member and the traction roller 1 driving member are the same component.

[0115] Since the above-mentioned traction roller grinding device has the above-mentioned technical effects, the sizing machine including the traction roller grinding device should have the same technical effects, which will not be described in detail here.

[0116] In addition, since the sizing machine and the above-mentioned traction roller grinding device are integrated, the traction roller 1 can be ground without disassembling it, which further improves the work efficiency.
