Description

Technical Field

[0001] This invention belongs to the field of rubber roller outer diameter processing technology, specifically, it relates to a device for grinding the outer diameter of high-precision polarizing film rubber rollers. Background Technology

[0002] High-precision polarizer rollers are core industrial components specifically designed for polarizer production. Their core function is to ensure high-precision, defect-free processing of polarizers during precision processes such as coating, lamination, and calendering. After the polarizer rollers have undergone shearing, burrs or micro-cracks may remain on their sides. These defects need to be removed through grinding to prevent scratching the polarizer surface during subsequent coating or lamination processes.

[0003] For grinding the surface of high-precision polarizing film rollers, a step-by-step grinding process is typically used to gradually improve the grinding precision, rather than grinding to completion in one go. This process can progressively optimize the roller surface precision, surface quality, and material properties. However, existing roller grinding methods use multiple pieces of equipment with different grinding precision for separate grinding, which requires multiple transfers and installations of the rollers, making the operation cumbersome. Summary of the Invention

[0047] Please refer to Figures 1-6 The present application provides a technical scheme: a device for high-precision grinding of the outer circle of a polarizer roller 1, comprising a support 2, a support frame, a sliding frame 3, a grinding unit, a first driving assembly, a transmission unit and an adjusting structure.

[0048] Please refer to Figure 1 The support 2 serves as the basic support structure of the entire device and provides a mounting base for other components.

[0049] Please refer to Figure 3 The support frame is fixed on the support 2, and the support frame is used to support the two ends of the horizontally arranged roller 1, and the roller 1 can rotate relative to the support frame. It should be noted that during the grinding process of the outer circle surface of the roller 1, the roller 1 can be manually driven to rotate, or it can be driven by a driving structure connected to the center shaft of the roller 1, and the roller 1 is driven to rotate by the driving structure. The support frame is used to support the two ends of the horizontally arranged roller 1, and the roller 1 can rotate relative to the support frame. This provides the condition for the rotational movement of the roller 1, so that the roller 1 can rotate continuously during the grinding process, so that each part of the outer circle can be ground.

[0050] Please refer to Figure 3The sliding frame 3 is arranged on the support 2 along the length direction of the rubber roller 1, and is a mounting carrier of multiple grinding units. The sliding movement of the sliding frame 3 drives the grinding units to move along the length direction of the rubber roller 1, so as to realize grinding processing of different positions of the outer circle of the rubber roller 1. The moving mode of the sliding frame 3 can be that the sliding frame 3 is manually pushed to move, or the sliding frame 3 is pushed to move by a hydraulic push rod or the like.

[0051] Referring to Figure 3 , the grinding units are multiple, and the multiple grinding units are sequentially arranged along the length direction of the rubber roller 1 and movably arranged on the sliding frame 3. This arrangement mode enables the multiple grinding units to sequentially process the outer circle of the rubber roller 1 in sequence under the driving of the sliding frame 3. Each grinding unit has a first direction and a second direction opposite to the first direction when the sliding frame 3 slides on the support 2. In this embodiment, as shown in Figure 3 , the moving direction to the right is the first direction, and the moving direction to the left is the second direction.

[0052] Referring to Figure 3 , when the sliding frame 3 slides along the first direction, each grinding unit has a disengagement phase of disengaging from the outer circle of the rubber roller 1 and a contact phase of contacting the outer circle of the rubber roller 1 in sequence. In the disengagement phase, the grinding unit does not contact the outer circle of the rubber roller 1, so that the grinding unit does not produce grinding effect on the outer circle of the rubber roller 1. In the contact phase, the grinding unit contacts the outer circle of the rubber roller 1, so that the grinding unit produces grinding effect on the outer circle of the rubber roller 1. The grinding precision of the multiple grinding units on the outer circle of the rubber roller 1 increases in sequence in the contact phase, so as to realize step-by-step polishing of the outer circle of the rubber roller 1 from coarse to fine.

[0053] Specifically, when the sliding frame 3 slides along the first direction, each grinding unit is first in a state of disengaging from the outer circle of the rubber roller 1, at which time the grinding unit does not contact the rubber roller 1 and does not perform grinding work. As the sliding frame 3 continues to slide along the first direction, the multiple grinding units enter a state of contacting the outer circle of the rubber roller 1 in sequence, and the grinding precision of the multiple grinding units on the outer circle of the rubber roller 1 increases in sequence in the contact phase. This design enables the outer circle of the rubber roller 1 to gradually achieve higher precision requirements in the processing process. First, the grinding unit with lower precision performs preliminary grinding to remove most of the surface defects, thereby creating a good foundation for subsequent fine processing. Then, the grinding unit with higher precision performs fine finishing to improve the dimensional accuracy and shape accuracy, thereby realizing high-precision processing effect and meeting the requirements of the rubber roller 1 on the surface quality. In addition, compared with the processing mode of a single grinding unit, this processing mode in which multiple grinding units simultaneously participate in processing and sequentially contact the outer circle of the rubber roller 1 for grinding greatly improves the processing efficiency and shortens the processing cycle.

[0054] It should be noted that in the contact stage of the grinding unit, the stroke of the grinding unit should make the last grinding unit complete the grinding of the outer circle of the rubber roller 1. That is, the leftmost grinding unit moves along the length direction of the rubber roller 1 by a distance that enables the outer circle of the rubber roller 1 to be completely ground. In other words, the leftmost grinding unit can move from the leftmost end of the rubber roller 1 to the rightmost end of the rubber roller 1.

[0055] When the sliding frame 3 slides along the second direction, the grinding unit enters the reset stage to make the sliding frame 3 return to the initial position and thus prepare for the grinding of the next rubber roller 1. It should be noted that when the grinding unit enters the reset stage, there are two usage modes: one, the grinding unit does not contact the outer circle of the rubber roller 1 during the reset stage and does not produce grinding action on the outer circle of the rubber roller 1, in which case the sliding frame 3 can be continuously driven to move for one cycle (i.e., the disengagement stage, the contact stage, and the reset stage) and then the rubber roller 1 can be replaced. Two, the grinding unit contacts the outer circle of the rubber roller 1 during the reset stage and produces grinding action on the outer circle of the rubber roller 1, in which case the sliding frame 3 can be continuously driven to move for half a cycle (i.e., the disengagement stage and the contact stage) and then the rubber roller 1 can be replaced, and then the sliding frame 3 is driven to move for the remaining half cycle, i.e., the reset stage. In this way, even if the grinding unit has the possibility of contacting the outer circle of the rubber roller 1, since the rubber roller 1 has been disassembled, it will not affect the rubber roller 1 that has been ground. After the reset stage is completed, a new rubber roller 1 to be ground is installed.

[0056] The first driving assembly is provided on the sliding frame 3, and the first driving assembly provides a power source for the grinding unit and is a component for driving the grinding unit to operate. The first driving assembly transmits power to each grinding unit through the transmission unit, so that the grinding unit can perform grinding operation on the outer circle of the rubber roller 1.

[0057] The transmission unit is the same number as the grinding unit, and each transmission unit is provided one-to-one between the first driving assembly and each grinding unit, and is respectively used to transmit power of the first driving assembly to each grinding unit to respectively realize the operation of each grinding unit. Each transmission unit respectively transmits power of the first driving assembly to each grinding unit to respectively realize the operation of each grinding unit. This one-to-one transmission mode can enable each grinding unit to independently obtain the power provided by the first driving assembly, and the first driving assembly can simultaneously realize the operation of multiple grinding units, thereby reducing the driving source for driving the grinding unit to operate, saving energy and reducing equipment cost.

[0058] The adjusting structure is used to adjust the position of the grinding units to realize the contact between the grinding units and the outer circle of the rubber roller 1. Through the adjusting structure, the plurality of grinding units are sequentially moved to the end position of the rubber roller 1, i.e. the leftmost position in the embodiment. That is, when the grinding units are transitioned from the disengagement phase to the contact phase, the grinding units are sequentially moved to the outer circle of the rubber roller 1 and respectively contacted with the outer circle of the rubber roller 1. In the contact phase, the transmission unit can transmit the power of the first driving assembly to the grinding units to drive the grinding units to operate, so that the grinding units are powered to perform grinding processing in the correct position. The position adjustment capability of the grinding units can control the contact position and grinding timing of each grinding unit with the outer circle of the rubber roller 1, and the grinding of the rubber roller 1 can be started from the end of the outer circle of the rubber roller 1, thereby realizing relatively complete grinding of the outer circle of the rubber roller 1. In addition, the grinding units only operate when they are in contact with the rubber roller 1, so that the grinding units do not operate when they are not in contact with the outer circle of the rubber roller 1, i.e. not grinding, thereby saving energy.

[0059] The specific use process is as follows:

[0060] Step one: place the rubber roller 1 to be ground horizontally on the support frame, so that the two ends of the rubber roller 1 are accurately supported on the support frame, and ensure that the rubber roller 1 can rotate freely relative to the support frame. The rubber roller 1 can be manually rotated, or the center shaft of the rubber roller 1 can be drivingly connected with the driving structure to drive the rubber roller 1 to rotate by the driving structure.

[0061] Step two: place the sliding frame 3 in the initial position, so that the plurality of grinding units are in a disengaged state from the outer circle of the rubber roller 1, i.e. the grinding units are not in contact with the outer circle of the rubber roller 1 and do not produce grinding effect on the outer circle of the rubber roller 1.

[0062] Step three: start the first driving assembly, and the first driving assembly starts to operate to provide power for the operation of the subsequent grinding units.

[0063] Step four: drive the sliding frame 3 to start sliding in the first direction (e.g. the right moving direction), and in the initial sliding stage, the plurality of grinding units are still in the disengaged state from the outer circle of the rubber roller 1 and do not perform grinding operation.

[0064] Continue to slide the sliding frame 3, and the plurality of grinding units are sequentially brought into contact with the outer circle of the rubber roller 1. When the plurality of grinding units are sequentially moved to the end position of the rubber roller 1 (e.g. the leftmost position) and are transitioned from the disengagement phase to the contact phase, the adjusting structure moves the grinding units to the outer circle of the rubber roller 1 and respectively contacts with the outer circle of the rubber roller 1.

[0065] In the contact stage, the grinding accuracy of the outer circle of the rubber roller 1 is increased in turn by the plurality of grinding units. The grinding unit with lower accuracy contacts the outer circle of the rubber roller 1 first to perform preliminary grinding, removing most of the excess and surface defects. As the sliding frame 3 continues to slide, the grinding unit with higher accuracy contacts the outer circle of the rubber roller 1 in turn to perform fine finishing, improving the dimensional accuracy and shape accuracy. The transmission unit accurately transmits the power of the first driving assembly to each grinding unit in the contact stage, so that the grinding unit obtains power for grinding at the correct position.

[0066] Step five: If the grinding unit does not contact the outer circle of the rubber roller 1 at all during the reset stage, drive the sliding frame 3 to slide in the second direction (e.g. leftward) to make the grinding unit enter the reset stage. During this process, the grinding unit does not perform grinding action on the outer circle of the rubber roller 1. After the sliding frame 3 returns to the initial position, stop driving the sliding frame 3, and then replace the rubber roller 1.

[0067] If the grinding unit will contact the outer circle of the rubber roller 1 during the reset stage, first drive the sliding frame 3 to slide in the first direction for half a cycle (i.e. disengagement stage and contact stage), complete part of the grinding, stop driving the sliding frame 3, and replace the rubber roller 1. At this time, since the grinding unit has completed part of the grinding and the rubber roller 1 has been removed, even if the sliding frame 3 is driven to slide in the second direction for the remaining half cycle (reset stage), even if the grinding unit can contact the outer circle of the rubber roller 1, it will not affect the rubber roller 1 that has been removed. After the reset stage is completed, install a new rubber roller 1 to be ground.

[0068] Step six: Place the new polarizing plate rubber roller 1 to be ground horizontally on the support frame, so that the two ends of the rubber roller 1 are accurately supported on the support frame, and the rubber roller 1 can rotate freely relative to the support frame. It can still be rotated manually or driven by a driving structure.

[0069] Step seven: Repeat steps two to five to grind the outer circle of the new rubber roller 1 until all the rubber rollers 1 are processed.

[0070] Step eight: After processing is completed, turn off the first driving assembly and clean the device to remove debris and impurities generated during grinding, keeping the device clean.

[0071] Referring to Figure 2 and 5 In this embodiment: the grinding unit is the core part of the entire device to realize the grinding function, including the adjusting wheel 4 and two fixed wheels 5. Both fixed wheels 5 are rotationally connected to the sliding frame 3. The main function of the fixed wheel 5 is to provide stable support and transmission path for the sand belt 6, so that the sand belt 6 can maintain a relatively stable position and shape during operation.

[0072] The sand belt 6 is arranged between the adjusting wheel 4 and the two fixed wheels 5, and the adjusting wheel 4 and the two fixed wheels 5 form a triangular structure through the sand belt 6 and are connected in transmission through the sand belt 6. The triangular structure enables the sand belt 6 to form a relatively stable grinding area. The adjusting wheel 4 has a rotating shaft 7, which is a key component for the rotation of the adjusting wheel 4 and enables the adjusting wheel 4 to rotate flexibly within a certain range.

[0073] The sliding frame 3 is located above the rubber roller 1 and provides a track for the grinding unit to move and support the grinding unit, so that the grinding unit can be adjusted in position along with the sliding frame 3 to grind the outer circle of the rubber roller 1 more completely. The first sliding block 8 is slidably connected to the sliding frame 3 in the vertical direction, and can freely slide on the vertical track of the sliding frame 3. The first sliding block 8 drives the adjusting wheel 4 to move up and down, thereby adjusting the fit between the grinding surface of the sand belt 6 and the outer circle of the rubber roller 1.

[0074] The rotating shaft 7 of the adjusting wheel 4 is rotatably connected to the first sliding block 8, so that the adjusting wheel 4 can move along with the first sliding block 8 while maintaining its rotation function. The transmission rod 9 is fixed to the first sliding block 8 in the vertical direction, and the function of the transmission rod 9 is to transmit external power or adjustment force to the first sliding block 8, thereby driving the first sliding block 8 to slide up and down. When the first sliding block 8 slides downward along with the transmission rod 9, the adjusting wheel 4 moves downward, which enables the grinding surface of the sand belt 6 to closely fit the outer circle of the rubber roller 1, so that the grinding process can be effectively carried out. At the same time, with the downward movement of the adjusting wheel 4, the sand belt 6 changes from a relaxed state to a tensioned state, and the tensioned sand belt 6 can provide more stable grinding force, further improving the accuracy and quality of grinding. In addition, the sand belt 6 remains relaxed in the non-working state, which can reduce material fatigue caused by continuous tensioning, and long-term tensioning can cause the elastic loss of the sand belt 6 substrate, accelerating the shedding or breaking of abrasive particles, while intermittent tensioning can reduce this risk.

[0075] It should be noted that the adjusting wheel 4 and the two fixed wheels 5 form a triangular structure through the sand belt 6, and the adjusting wheel 4 can tension the sand belt 6 when it moves downward. Therefore, the positional relationship between the adjusting wheel 4 and the fixed wheels 5 needs to be described, one of the fixed wheels 5 is directly above the other fixed wheel 5, the adjusting wheel 4 is located between the two fixed wheels 5 close to the rubber roller 1. However, the positional relationship between the adjusting wheel 4 and the fixed wheels 5 is not limited to the above, as long as the sand belt 6 can be tensioned when the adjusting wheel 4 moves downward. The above is only a specific embodiment that can be implemented.

[0076] Referring to Figure 3The adjusting structure is an adjusting rod 10, which is located above the transmission rod 9. The main function of the adjusting rod 10 is to provide adjustment and guidance for the movement of the transmission rod 9, so as to control the position of the adjusting wheel 4, and then adjust the fit of the abrasive belt 6 and the outer circle of the rubber roller 1. The adjusting rod 10 is arranged along the length direction of the rubber roller 1.

[0077] Referring to Figure 6 The lower side of the adjusting rod 10 is provided with a horizontal first face 11 and a second face 12. The first face 11 is higher than the second face 12. The height difference is designed to form different adjustment positions. The first face 11 and the second face 12 are provided with a first inclined face 13, which is arranged to be inclined upward near the side of the first face 11. The design of the first inclined face 13 can not only cause the displacement of the transmission rod 9, but also gradually change the position of the transmission rod 9 through the slope of the first inclined face 13, so as to realize the slow and stable movement of the adjusting wheel 4, effectively avoid the sudden change of the position, and avoid the sudden change of the tension of the abrasive belt 6, which affects the grinding quality.

[0078] Referring to Figure 4 The transmission rod 9 is provided with a first elastic member 14. The first elastic member 14 provides an initial thrust for the transmission rod 9, pushes the transmission rod 9 to the first face 11, and makes the adjusting wheel 4 be in an initial and relatively high position. At this time, the abrasive belt 6 is in a relatively relaxed state. When it is necessary to tighten the abrasive belt 6 and make it fit with the outer circle of the rubber roller 1, the transmission rod 9 moves along with the sliding frame 3 along the length direction of the rubber roller 1 by moving the sliding frame 3. The transmission rod 9 will move from the first face 11 to the second face 12, and in the process, the transmission rod 9 will slide along the first inclined face 13. Due to the slope of the first inclined face 13, the transmission rod 9 will gradually press the first sliding block 8 downward in the sliding process, and then make the adjusting wheel 4 move downward. The downward movement of the adjusting wheel 4 makes the abrasive belt 6 gradually tighten, and closely fit with the outer circle of the rubber roller 1, so as to realize the grinding processing. When the transmission rod 9 slides along the second face 12, the abrasive belt 6 is always in a tension state and keeps in contact with the outer circle of the rubber roller 1, that is, the above-mentioned contact stage. Thus, the complete grinding of the outer circle of the rubber roller 1 can be realized by moving the sliding frame 3. The design of the mutual cooperation of the adjusting rod 10, the first elastic member 14 and the transmission rod 9 can realize the synchronous control of the tightening degree of the abrasive belt 6 and the fit degree of the grinding surface, and improve the grinding processing efficiency of the high-precision polaroid rubber roller 1 outer circle while considering the durability of the abrasive belt 6.

[0079] Specifically, the first elastic member 14 is a spring which is sleeved outside the transmission rod 9. One end of the spring is fixedly connected with the sliding frame 3, and the other end is fixedly connected with the transmission rod 9.

[0080] Referring to Figure 1 and 5In the embodiment, the lower side of the adjusting rod 10 has a second inclined surface 15 and a third surface 16, the third surface 16 is in the same horizontal line with the first surface 11, the second inclined surface 15 is opposite to the first inclined surface 13 in the inclination direction, the first surface 11, the first inclined surface 13, the second surface 12, the third inclined surface and the third surface 16 form a track for the continuous movement of the transmission rod 9, and the transmission rod 9 can drive the sand belt 6 to relax, tighten and loosen when moving in the track.

[0081] In the initial preparation stage of the grinding process, the transmission rod 9 is in the first surface 11 under the pushing action of the first elastic member 14, at this time the sand belt 6 is in a relatively relaxed initial state, which provides a stable starting point for subsequent adjustment and processing operations. When the transmission rod 9 moves from the first surface 11 to the second surface 12, it will pass through the first inclined surface 13. The first inclined surface 13 is upwardly inclined near the first surface 11, when the transmission rod 9 slides down along the first inclined surface 13, the vertical component force will press the transmission rod 9 downward. The downward movement of the transmission rod 9 drives the first sliding block 8 and the adjusting wheel 4 to move downward, the downward movement of the adjusting wheel 4 increases the circumference of the triangular shape formed by the adjusting wheel 4 and the two fixed wheels 5, so that the sand belt 6 is subjected to greater tension, and the sand belt 6 gradually changes from a relaxed state to a tight state and closely fits on the outer circle of the rubber roller 1. The tightened sand belt 6 can provide stable and sufficient grinding force.

[0082] When the transmission rod 9 moves from the second surface 12 to the third surface 16 along the second inclined surface 15, the transmission rod 9 will be pushed upward by the first elastic member 14 due to the inclination of the second inclined surface 15. The upward movement of the transmission rod 9 drives the first sliding block 8 connected thereto to move upward, and the first sliding block 8 further drives the adjusting wheel 4 to move upward. With the upward movement of the adjusting wheel 4, the tension on the sand belt 6 gradually decreases, and the sand belt 6 gradually loosens. This loosening state is necessary in some cases, for example, when replacing the sand belt 6, checking the surface of the rubber roller 1 or performing some operations that do not require the sand belt 6 to be closely fitted, the loosened sand belt 6 can avoid unnecessary wear on the surface of the rubber roller 1, and also facilitates the relevant operations of the operator.

[0083] Referring to Figure 1 and 5 In the embodiment, a convex-shaped groove 17 is formed on the second surface 12, the narrow side of the convex-shaped groove 17 is close to the transmission rod 9, the convex-shaped groove 17 extends along the length direction of the adjusting rod 10, and the two ends of the convex-shaped groove 17 extend out of the first inclined surface 13 and the second inclined surface 15 respectively.

[0084] The middle position of the transmission rod 9 away from the adjusting wheel 4 has an abutting ball 18, the diameter of the abutting ball 18 is larger than the diameter of the transmission rod 9, the abutting ball 18 is located directly below the convex-shaped groove 17, the diameter of the abutting ball 18 is larger than the size of the narrow side of the convex-shaped groove 17 and smaller than the size of the wide side of the convex-shaped groove 17, and the diameter of the transmission rod 9 is smaller than the size of the narrow side of the convex-shaped groove 17.

[0085] The abutting ball 18 abuts on the narrow side of the convex-shaped groove 17, the abutting ball 18 can move along the length direction of the convex-shaped groove 17, but cannot enter the convex-shaped groove 17 from the narrow side of the convex-shaped groove 17, when the abutting ball 18 abuts on the first face 11 or the third face 16, it can enter the convex-shaped groove 17 from the end of the convex-shaped groove 17, and the transmission rod 9 can be clamped into the narrow side of the convex-shaped groove 17.

[0086] The connecting position of the first face 11 and the first inclined face 13 is rotationally connected with a cover plate 19 for closing the end of the convex-shaped groove 17, and the cover plate 19 is provided with a second elastic element 20 for pushing the cover plate 19 against the first inclined face 13. Specifically, the second elastic element 20 is a torsion spring. The cover plate 19 is rotationally connected with the connecting position of the first face 11 and the first inclined face 13 through a shaft body, the torsion spring is installed on the shaft body, one torsion arm of the torsion spring is fixedly connected with the adjusting rod 10, and the other torsion arm abuts against the side of the cover plate 19 away from the convex-shaped groove 17.

[0087] When the transmission rod 9 moves from the first face 11 and moves towards the second face 12, at this time, the cover plate 19 is in a state of closing the end of the convex-shaped groove 17. The cover plate 19 closely fits the end of the convex-shaped groove 17, which is very important. On the one hand, it effectively prevents dust, impurities and the like from the outside from entering the inside of the convex-shaped groove 17, because in the actual working environment, various tiny particles will inevitably float, if these impurities enter the convex-shaped groove 17, they may be stuck between the abutting ball 18 and the convex-shaped groove 17, affecting the smooth movement of the abutting ball 18, and further causing the movement of the transmission rod 9 to be blocked, so that the entire sand belt 6 tension adjusting system fails. On the other hand, the cover plate 19 and the convex-shaped groove 17 provide a clear movement track for the abutting ball 18, which can accurately move upwards to the second face 12 along the established path under the guidance of the cover plate 19.

[0088] When the abutting ball 18 moves up to the second surface 12, the abutting ball 18 is designed to be closely fitted to the narrow side of the convex-shaped groove 17 and not to fall into the convex-shaped groove 17 due to its size (the diameter is larger than the size of the narrow side of the convex-shaped groove 17 and smaller than the size of the wide side of the convex-shaped groove 17, and the diameter of the transmission rod 9 is smaller than the size of the narrow side of the convex-shaped groove 17). Meanwhile, the position and structure of the second surface 12 determine the position of the adjusting wheel 4 at this point. The adjusting wheel 4 moves downward and exerts tension on the abrasive belt 6 through the linkage of the transmission rod 9 and the abutting ball 18, so that the abrasive belt 6 is closely fitted to the outer circle of the rubber roller 1, thereby providing stable and appropriate grinding force for subsequent grinding.

[0089] When the abutting ball 18 moves on the second surface 12 and then falls into the third surface 16 and moves back from the third surface 16, the abutting ball 18 enters the convex-shaped groove 17 from the end of the convex-shaped groove 17 away from the cover plate 19, and the transmission rod 9 is stably clamped in the narrow side of the convex-shaped groove 17. This clamping state ensures the stability of the transmission rod 9 during the return movement, reducing the possibility of the transmission rod 9 shaking or deviating from the track. At this time, the upward movement of the abutting ball 18 causes the abrasive belt 6 to be in a non-tensioned and non-fitted state, i.e., the grinding unit does not affect the rubber roller 1 during the reset stage.

[0090] Referring to Figure 4 When the transmission rod 9 needs to enter or exit the convex-shaped groove 17 from the end of the convex-shaped groove 17 during the return movement of the transmission rod 9 to the cover plate 19, the transmission rod 9 will overcome the elastic force of the second elastic member 20 by its own moving force. The second elastic member 20 normally pushes the cover plate 19 tightly against the first inclined surface 13 by its elastic force, maintaining the closed state of the end of the convex-shaped groove 17. However, when the transmission rod 9 needs to enter or exit the convex-shaped groove 17, the pressure exerted by the transmission rod 9 on the cover plate 19 is greater than the elastic force of the second elastic member 20, and the cover plate 19 is pushed away, providing a passage for the transmission rod 9. After the transmission rod 9 passes smoothly, the second elastic member 20 quickly exerts its elastic force to push the cover plate 19 back to its original position, continuing to play its guiding role. In summary, the cover plate 19 and the convex-shaped groove 17 enable the abutting ball 18 to move in a circular manner along the first surface 11 (cover plate 19), the first inclined surface 13, the second surface 12, the second inclined surface 15, the third surface 16, the convex-shaped groove 17 (when moving back, the abutting ball 18 enters the interior of the convex-shaped groove 17), and the first surface 11.

[0091] By the convex-shaped groove 17 and the abutting ball 18, the transmission rod 9 is in the back movement (i.e. the reset stage), the abutting ball 18 is located in the convex-shaped groove 17 (when the abutting ball 18 is located in the convex-shaped groove 17, the transmission rod 9 will move up a distance under the action of the first elastic member 14 so that the abrasive belt 6 is relaxed and not in contact with the rubber roller 1), the grinding unit will not interfere with the rubber roller 1 in the reset stage, and the replacement of the rubber roller 1 can be performed after the grinding unit is reset, which is simple to operate.

[0092] Referring to Figure 2 In the embodiment, the first driving assembly includes a first driving member 21 and a transmission shaft 22, the first driving member 21 is installed on the sliding frame 3, the output end of the first driving member 21 is in transmission connection with the transmission shaft 22, and the transmission shaft 22 is arranged along the length direction of the rubber roller 1.

[0093] The transmission unit includes a first transmission wheel 23 coaxially arranged on the transmission shaft 22, the sliding frame 3 is rotationally connected with a second transmission wheel 24, the second transmission wheel 24 is coaxially fixedly connected with a first gear 25, and the rotating shaft 7 is coaxially fixedly connected with a second gear 26, when the abutting ball 18 abuts against the second surface 12, the first gear 25 is in meshing connection with the second gear 26.

[0094] The sliding frame 3 itself can be flexibly moved on a specific track or structure, the first driving member 21 is installed on the sliding frame 3, so that the first driving member 21 can adjust the position along with the movement of the sliding frame 3. The output end of the first driving member 21 is in transmission connection with the transmission shaft 22, so that the power generated by the first driving member 21 can be transmitted to the transmission shaft 22. The transmission shaft 22 is carefully arranged along the length direction of the rubber roller 1, and such an arrangement makes the transmission shaft 22 uniformly distribute the power to each transmission unit related to each grinding unit, thereby providing power support for the subsequent grinding unit.

[0095] The first transmission wheel 23 coaxially arranged on the transmission shaft 22 is a power receiving end of the transmission unit. When the first driving assembly starts to work, the transmission shaft 22 rotates, and the first transmission wheel 23 rotates synchronously with the transmission shaft 22, thereby introducing the power transmitted by the transmission shaft 22 into the transmission unit. The second transmission wheel 24 rotationally connected to the sliding frame 3 plays an important role in power transmission and direction conversion. It cooperates with the first transmission wheel 23 to transmit the power of the first transmission wheel 23 through belt transmission or chain transmission (the specific transmission mode can be determined according to the actual design). The second transmission wheel 24 is coaxially fixedly connected with the first gear 25, and such a coaxial fixed connection mode ensures the rotation synchronism of the second transmission wheel 24 and the first gear 25, that is, when the second transmission wheel 24 rotates, the first gear 25 rotates at the same angular velocity. The second gear 26 is coaxially fixedly connected to the rotating shaft 7, and the rotating shaft 7 is connected with the adjusting wheel 4 in the whole device, and the rotation state of the adjusting wheel 4 directly affects the use of the abrasive belt 6.

[0096] When the abutting ball 18 is abutted against the second surface 12, at this time the abrasive belt 6 is in a state of being tightly stretched, and a specific processing operation needs to be carried out. At this time, the first gear 25 is precisely engaged with the second gear 26, and when the first gear 25 rotates with the second transmission wheel 24, the power is accurately transmitted to the second gear 26 through the mutual engagement of the teeth of the gears. The second gear 26 drives the rotating shaft 7 to rotate, and the rotation of the rotating shaft 7 further drives the adjusting wheel 4 to move, and the rotation of the adjusting wheel 4 can make the abrasive belt 6 rotate to form grinding on the rubber roller 1.

[0097] Specifically, the first driving member 21 is a first motor, the first motor is installed on the sliding frame 3, the output shaft of the first motor is coaxially arranged with the transmission shaft 22, and the output shaft of the first motor and the transmission shaft 22 are connected through a shaft coupling.

[0098] Referring to Figure 1 In the embodiment, the support 2 is provided with a second driving assembly for driving the sliding frame 3 to move back and forth, the second driving assembly comprises a reciprocating screw rod 27 and a second driving member 28 for driving the reciprocating screw rod 27 to rotate, the reciprocating screw rod 27 is arranged along the length direction of the rubber roller 1, the reciprocating screw rod 27 is rotatably connected with the support 2, the second sliding block 29 is arranged on the reciprocating screw rod 27, and the second sliding block 29 is fixedly connected with the sliding frame 3. By rotating the reciprocating screw rod 27, the second sliding block 29 can move back and forth along the reciprocating screw rod 27.

[0099] The second driving assembly mainly comprises the reciprocating screw rod 27 and the second driving member 28 for driving the reciprocating screw rod 27 to rotate. The reciprocating screw rod 27 is arranged along the length direction of the rubber roller 1, and this layout is closely related to the overall structure and working requirement of the rubber roller 1. Because the working range of the rubber roller 1 during the polaroid outer circle grinding processing usually expands along the length direction of the rubber roller 1, the arrangement of the reciprocating screw rod 27 along this direction can ensure that the moving direction of the sliding frame 3 matches the processing requirement, thereby realizing effective operation on different positions of the rubber roller 1. The reciprocating screw rod 27 is rotatably connected with the support 2, and this connection mode ensures that the reciprocating screw rod 27 can flexibly rotate under the driving of the second driving member 28. Its working principle is similar to that of the common screw rod transmission mechanism. The reciprocating screw rod 27 has a special thread structure on the surface. This thread is not an ordinary continuous thread, but a thread groove that reciprocates within a certain length range. When the reciprocating screw rod 27 rotates, the components arranged thereon can move back and forth.

[0100] The rotation of the reciprocating screw rod 27 is linked to the movement of the sliding frame 3 and the abutting ball 18 on the adjusting rod 10, specifically, the sliding frame 3 is driven by the reciprocating screw rod 27 to make a reciprocating movement, and the abutting ball 18 moves along the first surface 11 (the cover plate 19), the first inclined surface 13, the second surface 12, the second inclined surface 15, the third surface 16, the U-shaped groove 17 (when returning, the abutting ball 18 goes deep into the U-shaped groove 17), and the first surface 11 in one cycle. In this process, the rubber roller 1 does not need to be operated, and the step-by-step grinding of the rubber roller 1 can be realized, and the process does not interfere with the rubber roller 1, and only needs to replace the rubber roller 1 after one cycle to perform the next rubber roller 1 grinding work, which is relatively convenient to operate.

[0101] The second driving member 28 is the power source of the entire second driving assembly, which can output stable rotary power to drive the reciprocating screw rod 27 to rotate at a set speed and direction. The reciprocating screw rod 27 is provided with a second sliding block 29, and the second sliding block 29 is fixedly connected with the sliding frame 3. This connection mode enables the movement of the second sliding block 29 to be directly transmitted to the sliding frame 3. When the second driving member 28 drives the reciprocating screw rod 27 to rotate, due to the special thread structure of the reciprocating screw rod 27, the second sliding block 29 will move linearly along the thread groove of the reciprocating screw rod 27. Specifically, when the reciprocating screw rod 27 rotates clockwise, the second sliding block 29 will move in one direction along the thread groove; when the reciprocating screw rod 27 rotates counterclockwise, the second sliding block 29 will move in the opposite direction along the thread groove. Through this reciprocating movement, the second sliding block 29 can drive the sliding frame 3 to move back and forth along the length direction of the rubber roller 1.

[0102] Referring to Figure 1 In the embodiment, the support frame includes a sleeve 30 and a three-jaw chuck 31. The sleeve 30 is slidably arranged on the support frame 2 along the length direction of the rubber roller 1. The support frame 2 is provided with an adjusting structure 32, such as a screw rod, for driving the sleeve 30 to move. The screw rod is rotationally connected to the support frame 2, coaxially arranged with the sleeve 30, and fixedly connected to one end of the sleeve 30. The other end of the screw rod extends away from the three-jaw chuck 31. The sleeve 30 and the three-jaw chuck 31 are coaxially arranged horizontally. The sleeve 30 and the three-jaw chuck 31 are separated by a mounting space for mounting the rubber roller 1. The three-jaw chuck 31 is rotationally connected to the support frame 2 along its own axis. The specific mounting method can refer to the mounting method of the three-jaw chuck 31 on existing machine tools, which will not be described in detail in the embodiment. During installation, one end of the center shaft of the rubber roller 1 is fixed to the three-jaw chuck 31, and the other end is sleeved into the sleeve 30. Then, the sleeve 30 is moved towards the rubber roller 1 by the adjusting structure 32, so that the end of the center shaft of the rubber roller 1 away from the three-jaw chuck 31 gradually goes deep into the sleeve 30, and finally abuts against the end of the sleeve 30 to realize the installation of the rubber roller 1. The rotation of the three-jaw chuck 31 can realize the rotation of the rubber roller 1.

[0103] With reference to Figure 1 Figure 1 In this embodiment, the three-jaw chuck 31 is in transmission connection with the reciprocating screw rod 27. Through the transmission connection between the three-jaw chuck 31 and the reciprocating screw rod 27, the second driving member 28 can drive the three-jaw chuck 31 to rotate synchronously when driving the reciprocating screw rod 27 to rotate, thereby driving the rubber roller 1 to rotate. The rotation of the rubber roller 1 is connected with the back-and-forth movement of the sliding frame 3, which improves the degree of automation, reduces the driving source for driving the rubber roller 1 to rotate, saves the cost, and reduces the energy consumption.

[0104] Specifically, the second driving member 28 is a second motor, which is installed on the support 2. A third transmission wheel 33 is coaxially and fixedly connected to an output shaft of the second motor. A driving shaft 34 is coaxially and fixedly connected to the three-jaw chuck 31. A fourth transmission wheel 35 and a fifth transmission wheel 36 are coaxially and fixedly connected to the driving shaft 34. The fourth transmission wheel 35 is in transmission connection with the third transmission wheel 33 through a belt or a chain. A sixth transmission wheel 37 is coaxially and fixedly connected to the reciprocating screw rod 27. The sixth transmission wheel 37 is in transmission connection with the fifth transmission wheel 36 through a belt or a chain. The second motor drives the third transmission wheel 33 to rotate, which drives the fourth transmission wheel 35 to rotate. The fourth transmission wheel 35 drives the three-jaw chuck 31 to rotate through the driving shaft 34. The driving shaft 34 drives the fifth transmission wheel 36 to rotate, which drives the sixth transmission wheel 37 to rotate. The rotation of the sixth transmission wheel 37 drives the reciprocating screw rod 27 to rotate.
