[0005]针对现有技术的不足，本发明提供了一种球磨轮带在线修复装置及方法，解决了现有轮带在线修复装置中发热磨损、进给间隙导致切削精度低，以及缺乏表面前置清理引发二次划伤的技术问题
[0023] 1. This invention improves the structural stability and service life during cutting operations by setting up a pressure-bearing mechanism and an assembly mechanism. The pressure-bearing roller installed at the top of the pressure block forms a rolling contact with the bottom of the tire, converting the sliding friction of the support part into rolling friction, thus avoiding the problem of heat and wear under high load. At the same time, the radial support force provided by the pressure-bearing roller can offset the reaction force generated by the cutting tool. Combined with the lateral limiting of the contact wheel, it restricts the retraction and vibration of the equipment during the cutting process, ensuring the surface smoothness of the tire.

Abstract
Description
Technical Field
[0001] This invention relates to the field of machining technology, specifically to an online repair device and method for ball mill belts. Background Technology
[0002] As the main supporting component of large ball mill equipment, the ball mill belt is fitted on the outside of the cylinder and cooperates with the support roller. It is responsible for bearing the huge load during the operation of the equipment. Under long-term heavy load conditions and dusty environment, wear defects such as fatigue spalling, grooving or non-roundness appear on the surface of the belt. These defects will cause vibration during equipment operation, thereby accelerating the damage of related transmission components.
[0003] Currently, online repair technology is commonly used, which fixes the repair device to the side of the tire for on-site cutting to avoid downtime losses caused by disassembly and replacement. However, existing online repair devices still have mechanical defects in practical engineering applications. First, due to the extremely large mass of the tire and the need to maintain rotation during cutting, the cutting tool generates a huge radial reaction force. Existing devices use rigid support blocks to directly press against the tire for back support. Under extremely high normal pressure, a large amount of frictional heat is rapidly generated through pure sliding friction, leading to severe wear of the support components or even mechanical jamming, which cannot guarantee the stability of the cutting operation.
[0004] Existing cutting feed mechanisms mostly rely on conventional lead screw and nut pairs to directly push and pull the tool holder. Due to the inherent mechanical clearance of the threaded fit, the tool generates high-frequency vibration under heavy-load cutting conditions, and it is difficult for operators to achieve accurate micro-depth adjustment, resulting in the surface roughness after repair being difficult to meet the standards. In addition, the repair work environment contains a lot of dust and oil, and existing technologies generally lack a pre-cleaning mechanism for the surface to be processed. During the cutting process, uncleaned hard particles and newly generated iron filings are drawn into the compression zone where the tool and tire contact, causing secondary scratches on the newly cut flat metal surface and reducing the overall repair quality. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention provides an online repair device and method for ball mill belts, which solves the technical problems of heat-induced wear, low cutting accuracy due to feed clearance, and secondary scratches caused by the lack of pre-cleaning of the surface in existing online belt repair devices.

[0011] Preferably, the fine-tuning feed mechanism includes a first mounting block, which is fixedly connected to the top end of the bearing block. A second stud is threadedly connected to the outside of the first mounting block. A connecting column is rotatably connected to the outside of the second stud. A rotating column is rotatably connected to the outside of the connecting column. A rotating plate is rotatably connected to the outside of the rotating column. A bearing plate is rotatably connected to the top end of the rotating plate. A telescopic column is fixedly connected to the bottom end of the bearing plate. A spring is sleeved on the outside of the telescopic column. A second mounting block is fixedly connected to the top end of the bearing plate. A blade is threadedly connected to the top end of the second mounting block.
[0012] Preferably, the synchronous reciprocating debris removal mechanism includes a driven column, which is fixedly connected to the outside of the rotating shaft. Two collision blocks are fixedly connected to the outside of the driven column. A connecting plate is fixedly connected to the top of the second crossbar. A sliding rod is slidably connected inside the connecting plate. Two contact blocks are fixedly connected to the outside of the sliding rod. A sliding plate is fixedly connected to the outside of the sliding rod. A cleaning column is rotatably connected to the top of the sliding plate.
[0013] Preferably, the support plate is slidably connected inside the first mounting block, one end of the spring is fixedly connected inside the first mounting block, and the other end of the spring is fixedly connected to the bottom end of the support plate.
[0014] Preferably, the connecting block and the bearing block are both slidably connected to the outside of the screw, and the driven shaft is rotatably connected to the inside of the second crossbar.
[0015] Preferably, the collision block is in contact with the contact block, and the two contact blocks are symmetrically distributed on the outside of the sliding rod.
[0016] A second aspect of the present invention provides a method for using an online repair device for ball mill belts, the method comprising the following steps:
[0017] The device is supported by a first crossbar and a second crossbar. During assembly, the connecting rod is placed inside the first crossbar. The position of the upright block, the connecting rod and the first crossbar is fixed by rotating the first stud. The position of the first fixing block and the first crossbar is fixed by rotating the first stud, and then the position of the first fixing rod and the mounting plate is fixed.
[0018] When using the device, place it at the bottom of the tire. When the tire rotates, it will drive the abutment wheel to rotate inside the fixed plate. The rotation of the abutment wheel completes the positioning and support of the tire. Start the motor, and the motor will drive the rotating shaft to rotate, which in turn drives the driven shaft to rotate via the belt, which in turn drives the screw to rotate. The rotation of the screw causes the sliding block to drive the bearing block to slide horizontally. At the same time, the blade set at the top of the bearing block abuts against the bottom of the tire. As the tire rotates, the protruding area of the tire contacts the blade for cutting. The uneven parts are removed through contact cutting, thereby restoring the tire to a complete circle and a flat surface. In addition, the horizontal sliding of the bearing block causes the blade to move along the width of the tire to achieve full-width repair of the tire.
[0019] The cutting depth can be adjusted by fine-tuning the feed mechanism. Specifically, when deep machining is required, rotating the second stud causes the connecting stud to move slightly inward towards the interior of the first mounting block. This causes the rotating stud to rotate the rotating plate slightly around the outer edge of the bearing plate, thus pushing the bearing plate to extend slightly. This, in turn, causes the second mounting block to move the cutting tool slightly towards the tire working surface, thereby increasing the cutting depth. When shallow cutting is required, rotating the second stud in the opposite direction causes the connecting stud to rotate slightly, which in turn causes the bearing plate to move slightly downward. This, in turn, causes the cutting tool to move slightly in the opposite direction towards the tire working surface, thereby decreasing the cutting depth. During the slight up-and-down movement of the bearing plate, a spring can provide elastic buffering and reset, ensuring that the cutting tool maintains a relatively stable contact pressure.
[0020] The pressure block serves as a mounting base to support the pressure rollers, allowing the pressure rollers to roll and abut against the surface of the tire to form a support surface. The abutting rollers mainly guide and limit the tire from both sides, while the pressure rollers provide support to the tire after machining. This allows the assembly mechanism and the pressure mechanism to cooperate with each other to support the tire.
[0021] During the use of the device, when the motor drives the rotating shaft to rotate, it will simultaneously drive the driven column to rotate, which in turn causes the collision block to rotate. When the collision block rotates to a specified angle, it contacts the contact block. During the contact between the collision block and the contact block, the contact block can be driven to slide horizontally. When the collision block no longer contacts the contact block, another collision block contacts the corresponding contact block, which in turn drives the contact block to slide in the opposite direction. Through the reciprocating sliding of the contact block, the sliding rod can be driven to slide simultaneously, which in turn drives the sliding plate to slide, thereby driving the cleaning column to slide synchronously. By cleaning the contact area of the tire with the cleaning column, the dust, impurities and oil stains accumulated on the surface of the tire during use can be wiped away, preventing dust and impurities from embedding into the tool during cutting and causing surface scratches between the tool and the tire working surface.
[0022] This invention provides an online repair device and method for ball mill belts. It has the following beneficial effects:
[0023] 1. This invention improves the structural stability and service life during cutting operations by setting up a pressure-bearing mechanism and an assembly mechanism. The pressure-bearing roller installed at the top of the pressure block forms a rolling contact with the bottom of the tire, converting the sliding friction of the support part into rolling friction, thus avoiding the problem of heat and wear under high load. At the same time, the radial support force provided by the pressure-bearing roller can offset the reaction force generated by the cutting tool. Combined with the lateral limiting of the contact wheel, it restricts the retraction and vibration of the equipment during the cutting process, ensuring the surface smoothness of the tire.
[0024] 2. This invention utilizes a fine-tuning feed mechanism to achieve accurate control of the cutting depth and eliminate transmission backlash. When the operator rotates the second stud, the axial displacement of the second stud causes the rotating plate to deflect slightly through the rotating column, thereby converting the horizontal movement into a small amount of vertical feed of the bearing plate, which facilitates accurate adjustment of the cutting depth. In addition, the spring sleeved at the bottom of the bearing plate provides a continuous elastic preload, eliminates the mechanical fit clearance inside the mechanism, and plays a buffering role during the cutting process, maintaining the stability of the cutting tool contact pressure.
[0025] 3. This invention improves the cutting environment of the tool and optimizes the transmission structure of the whole machine by introducing the spindle power of the transverse feed drive mechanism, which drives the two collision blocks to rotate and alternately squeeze the symmetrically distributed contact blocks, converting the rotational motion into the reciprocating linear sliding of the cleaning column along the sliding rod. Through pure mechanical linkage, the tool movement and the tire surface cleaning are synchronized without the need for an external power source, eliminating the risk of chips and dust impurities getting stuck in the tool and preventing secondary scratches on the tire working surface.

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0034] Please see the appendix Figure 1 - Appendix Figure 6 This invention provides an online repair device for ball mill belts, including a first crossbar 1, which is the basic support component of the device. An assembly mechanism 2 is provided on the outside of the first crossbar 1, which is the positioning support mechanism of the device and is used to realize the installation and spacing adaptation of the device next to the belt. The assembly mechanism 2 includes a vertical block 21, which is the end support component and forms the connecting base between the assembly mechanism 2 and the first crossbar 1. The vertical block 21 is located on the outside of the first crossbar 1 and can slide along the axial direction of the first crossbar 1, so as to facilitate the adjustment of the support installation position according to the width of the belt. A first stud 22 is abutted on the outside of the vertical block 21. The first stud 22 can be screwed in to abut against the outer wall of the first crossbar 1 to lock the sliding position of the vertical block 21 and prevent the device from shifting or deviating during operation.
[0035] The first stud 22 is externally threaded with a connecting rod 23. The connecting rod 23 is a transverse connecting piece that can connect the two upright blocks 21 into a whole, thereby improving the overall rigidity and vibration resistance of the device structure. The first horizontal bar 1 is externally provided with a first fixing block 24. The first fixing block 24 is located outside the first horizontal bar 1 and provides a vertical mounting base for the first fixing rod 25 and the mounting plate 26. The top of the first fixing block 24 is fixedly connected to the first fixing rod 25. The first fixing rod 25 is vertically arranged and used to support the mounting plate 26 and the fixing plate 27, so that the abutment wheel 28 can be adapted to the side height position of the tire.
[0036] The first fixed rod 25 is externally fixedly connected to a mounting plate 26. The mounting plate 26 is a central connecting part to ensure the stability of the installation of the fixed plate 27. The top of the mounting plate 26 is fixedly connected to a fixed plate 27. The fixed plate 27 is a plate-shaped structure that provides space for the rotation support of the abutment wheel 28. The abutment wheel 28 is rotatably connected inside the fixed plate 27. The abutment wheel 28 can roll against the side end face of the tire and play a lateral limiting and guiding role on the tire during the use of the device, so as to maintain the smooth operation of the device.
[0037] Please see the appendix Figure 1 - Appendix Figure 4 A transverse feed mechanism 3 is provided on the outside of the first crossbar 1. The transverse feed mechanism 3 is a mechanism that realizes the horizontal movement of the blade 510. It can drive the blade 510 to slide along the width direction of the tire to complete the repair operation of the entire width range of the tire. The transverse feed mechanism 3 includes a motor 31, which provides a power source for the transverse feed mechanism 3, ensuring uniform feed speed and improving cutting repair efficiency. The motor 31 is fixedly connected to the outside of the second crossbar 7. The second crossbar 7 and the first crossbar 1 together form the main supporting body of the device. Fixing the motor 31 to the second crossbar 7 can make the device structure layout compact and reduce transmission vibration during operation.
[0038] A rotating shaft 32 is fixedly connected to the output end of the motor 31. The rotating shaft 32 rotates synchronously with the output end of the motor 31, which can transmit the rotational power output by the motor 31 to the belt 33. The belt 33 is rotatably connected to the outside of the rotating shaft 32. The belt 33 can buffer the impact load during start-up, shutdown and cutting processes, and at the same time realize the power transmission between the rotating shaft 32 and the driven shaft 34. The driven shaft 34 is rotatably connected inside the belt 33. The driven shaft 34 rotates synchronously under the drive of the belt 33, and the power is transmitted to the driven shaft 34 to complete the speed matching of the transmission path. The driven shaft 34 is rotatably connected inside the second crossbar 7. The second crossbar 7 can provide rotational support for the driven shaft 34, limit the radial movement of the driven shaft 34, and ensure the stability of subsequent transmission.
[0039] A screw 35 is fixedly connected to the external side of the driven shaft 34. The screw 35 rotates synchronously with the driven shaft 34, converting rotary motion into reciprocating linear motion of the sliding block 36. The sliding block 36 is fixedly connected to the external side of the screw 35. Driven by the screw 35, the sliding block 36 moves horizontally, thereby driving the connecting block 37 to move synchronously. The connecting block 37 is fixedly connected to the external side of the sliding block 36. As an intermediate transition component, the connecting block 37 can distribute the transmission load and smoothly transmit the driving force of the sliding block 36 to the driven shaft 34. The bearing block 38 enhances the strength of the connection. The bearing block 38 is fixedly connected to the outside of the connecting block 37. The bearing block 38 provides a mounting carrier for the fine-tuning feed mechanism 5 and completes horizontal feed synchronously with the sliding block 36 and the connecting block 37. The connecting block 37 and the bearing block 38 are both slidably connected to the outside of the screw 35. The screw 35 also provides sliding guide constraints for the connecting block 37 and the bearing block 38 to ensure smooth reciprocating movement along the predetermined axial trajectory, driving the blade 510 to achieve cutting and repair of the tire across the full width range.
[0040] Please see the appendix Figure 1 - Appendix Figure 4 The first crossbar 1 is provided with a pressure-bearing mechanism 4 on its outside. The pressure-bearing mechanism 4 can provide support for the bottom of the tire and cooperate with the end assembly mechanism 2 to ensure the running stability of the tire during the cutting process. The pressure-bearing mechanism 4 includes a second fixing block 41, which is the bottom mounting base of the pressure-bearing mechanism 4. The second fixing block 41 is fixedly connected to the outside of the second crossbar 7. Relying on the rigid bearing capacity of the second crossbar 7, the second fixing block 41 can be prevented from shifting and deforming after being loaded, thus ensuring the stability of the pressure-bearing support position.
[0041] The top of the second fixing block 41 is fixedly connected to the second fixing rod 42. The second fixing rod 42 is arranged vertically to raise the installation height of the fixing column 43 and the pressure block 44, so that the pressure-bearing working surface can be adapted to the support position of the bottom of the tire. The second fixing rod 42 is fixedly connected to the fixing column 43. The fixing column 43 is the bearing component of the pressure block 44, which can disperse the support pressure transmitted by the pressure block 44 and improve the vibration resistance of the structure. The top of the fixing column 43 is fixedly connected to the pressure block 44. The pressure block 44 is the mounting bearing component of the pressure roller 45 and bears the vertical support load transmitted by the tire.
[0042] The top of the pressure block 44 is rotatably connected to a pressure roller 45. The pressure roller 45 can roll against the bottom of the tire to form a support surface, providing radial support for the tire during cutting operations. At the same time, it reduces friction loss with the tire through rolling contact. It works in conjunction with the lateral limit of the assembly mechanism 2 to ensure the smooth operation of the tire processing.
[0043] Please see the appendix Figure 1 - Appendix Figure 5The first crossbar 1 is provided with a fine-tuning feed mechanism 5. The fine-tuning feed mechanism 5 is used to achieve fine adjustment of the cutting depth and can adapt to the repair needs of different wear levels of the tire. The fine-tuning feed mechanism 5 includes a first mounting block 51, which is the mounting base of the fine-tuning feed mechanism 5 and provides the mounting foundation and motion constraint space for the internal structure. The first mounting block 51 is fixedly connected to the top of the bearing block 38. Relying on the horizontal sliding of the bearing block 38, the fine-tuning feed mechanism 5 can be driven to move along the width direction of the tire to ensure the synchronization of the repair operation in the full width range. The first mounting block 51 is connected to a second stud 52 by an external thread. The second stud 52 achieves fine feed by means of the small pitch of the external thread. It is an operating component for the operator to manually adjust the cutting depth and can convert the rotational action into the moving power of the bearing plate 56.
[0044] The second stud 52 is rotatably connected to a connecting post 53. The connecting post 53 rotates slightly axially with the rotation of the second stud 52, transmitting the power of the second stud 52 to the rotating plate 55, thus achieving a transfer of power direction. The connecting post 53 is rotatably connected to a rotating post 54, which can translate synchronously with the connecting post 53 and adapt to the deflection motion of the rotating plate 55, preventing jamming during transmission and ensuring smooth adjustment. The rotating post 54 is rotatably connected to a rotating plate 55, which rotates slightly about the outer edge of the bearing plate 56, allowing the connecting post 52 to rotate slightly. The horizontal movement of the connecting column 53 is converted into a small vertical displacement, realizing the micro-adjustment of the feed amount. The top of the rotating plate 55 is rotatably connected to the bearing plate 56, which is the vertical bearing component of the second mounting block 59. It can generate a small vertical displacement under the rotation of the rotating plate 55, thereby driving the blade 510 to complete the depth adjustment action. The bearing plate 56 is slidably connected inside the first mounting block 51. The first mounting block 51 provides vertical sliding guide constraint for the bearing plate 56, restricting the radial offset of the bearing plate 56 and ensuring that the movement direction of the blade 510 is perpendicular to the tire working surface.
[0045] A telescopic column 57 is fixedly connected to the bottom end of the bearing plate 56. The telescopic column 57 provides auxiliary guidance for the vertical movement of the bearing plate 56, prevents the bearing plate 56 from tilting during the lifting and lowering process, and ensures the stability and accuracy of the feed adjustment. A spring 58 is sleeved on the outside of the telescopic column 57. The spring 58 can provide a continuous elastic pre-tightening force for the bearing plate 56, eliminate the misalignment during the depth adjustment process. One end of the spring 58 is fixedly connected to the inside of the first mounting block 51. Fixing the bottom end of the spring 58 to the inner wall of the first mounting block 51 can provide a stable support base for the elastic force and ensure reliable buffer reset effect.
[0046] The other end of the spring 58 is fixedly connected to the bottom end of the support plate 56. The top end of the spring 58 acts on the bottom of the support plate 56, which can achieve elastic buffering and reset during the lifting and lowering of the support plate 56, so that the blade 510 maintains a stable contact pressure. The top end of the support plate 56 is fixedly connected to the second mounting block 59. The second mounting block 59 serves as the mounting part for the blade 510, which can provide a stable mounting position for the blade 510 and facilitate the disassembly, replacement and daily maintenance of the blade 510. The top end of the second mounting block 59 is threadedly connected to the blade 510. The blade 510 adjusts the cutting depth by slightly lifting and lowering the support plate 56, which can cut and remove uneven protrusions on the surface of the tire, so that the tire can be restored to a complete circle and a flat working surface.
[0047] Please see the appendix Figure 1 - Appendix Figure 6 The top of the fine-tuning feed mechanism 5 is equipped with a synchronous reciprocating chip removal mechanism 6. The synchronous reciprocating chip removal mechanism 6 can work in conjunction with the transverse feed mechanism 3 to complete the cleaning operation of the tire surface before the blade 510 cuts. The synchronous reciprocating chip removal mechanism 6 includes a driven column 61, which is the power input component of the synchronous reciprocating chip removal mechanism 6. It is used to receive the rotational power output by the rotating shaft 32, thereby driving the reciprocating synchronous reciprocating chip removal mechanism 6 to operate. The driven column 61 is fixedly connected to the outside of the rotating shaft 32. By fixing the outside of the rotating shaft 32, it can rotate synchronously with the rotating shaft 32 to realize the synchronization of the horizontal movement of the blade 510 and the cleaning action.
[0048] Two collision blocks 62 are fixedly connected to the external side of the driven column 61. The two collision blocks 62 rotate together with the driven column 61 and periodically and alternately contact and squeeze the contact block 63, providing driving force for the reciprocating sliding of the sliding rod 64. When the collision block 62 contacts the contact block 63, the rotational squeezing action of the collision block 62 can push the contact block 63 to produce axial displacement, converting the rotational motion into the linear sliding of the contact block 63. A connecting plate 65 is fixedly connected to the top of the second crossbar 7, which provides mounting support for the sliding rod 64. With the sliding guide reference, the stability of the reciprocating sliding process is ensured. The sliding rod 64 is slidably connected inside the connecting plate 65. The connecting plate 65 can limit the sliding direction of the sliding rod 64, so that the sliding rod 64 can move smoothly only in the axial direction and avoid deviation and jamming. The two contact blocks 63 are symmetrically distributed on the outside of the sliding rod 64. The symmetrical arrangement can make the force even and symmetrical when the two collision blocks 62 alternately touch and apply force, avoiding deviation and jamming of the sliding rod 64 due to force on one side, so that the cleaning column 67 can stably clean the working surface of the tire.
[0049] Two contact blocks 63 are fixedly connected to the outside of the sliding rod 64. The two contact blocks 63 can alternately bear the pushing force of the two sets of collision blocks 62, driving the sliding rod 64 to reciprocate and slide, ensuring that the cleaning action is continuous and uninterrupted. A sliding plate 66 is fixedly connected to the outside of the sliding rod 64. The sliding plate 66 can move axially synchronously with the sliding rod 64, transmitting the sliding force to the cleaning column 67, thereby completing the reciprocating cleaning action. The top of the sliding plate 66 is rotatably connected to the cleaning column 67. While the cleaning column 67 slides back and forth with the sliding plate 66, it rolls and contacts the tire to be processed area, wiping away the dust, impurities and oil stains accumulated on the surface, preventing impurities from embedding between the blade 510 and the tire working surface during cutting and causing surface scratches. The first crossbar 1 is fixedly connected to the second crossbar 7. The first crossbar 1 and the second crossbar 7 are arranged together to form the main supporting body of the device, providing a stable installation foundation for the device.
[0050] The method of using the online repair device for ball mill belts described below can be referred to in correspondence with the online repair device for ball mill belts described above.
[0051] The method includes the following steps: The device uses a first crossbar 1 and a second crossbar 7 as its main supporting body. During assembly, the connecting rod 23 is placed inside the first crossbar 1. The positions of the upright block 21, the connecting rod 23, and the first crossbar 1 are fixed by rotating the first stud 22. The first fixing block 24 and the first crossbar 1 are then fixed by rotating the first stud 22, thereby fixing the positions of the first fixing rod 25 and the mounting plate 26. When in use, the device is placed at the bottom of the tire. When the tire rotates, it drives the abutment wheel 28 to rotate inside the fixing plate 27. The rotation of the abutment wheel 28 completes the positioning and support of the tire. The motor 31 is started, and the motor 31 drives the rotation wheel 25 to rotate. The rotating shaft 32 drives the driven shaft 34 to rotate via the belt 33, which in turn drives the screw 35 to rotate. The rotation of the screw 35 causes the sliding block 36 to drive the bearing block 38 to slide horizontally. At the same time, the blade 510, which is located at the top of the bearing block 38, abuts against the bottom of the tire. As the tire rotates, the protruding area of the tire contacts the blade 510 for cutting. The uneven parts are removed through contact cutting, thereby restoring the tire to a complete circle and a flat surface. In addition, the horizontal sliding of the bearing block 38 causes the blade 510 to move along the width of the tire, so as to achieve the repair of the entire width of the tire.
[0052] The cutting depth can be adjusted by fine-tuning the feed mechanism 5. Specifically, when deep machining is required, rotating the second stud 52 causes the connecting stud 53 to move slightly inward toward the first mounting block 51, so that the rotating stud 54 drives the rotating plate 55 to rotate slightly around the outside of the bearing plate 56 as the axis, thereby pushing the bearing plate 56 to extend slightly. This causes the second mounting block 59 to move the cutting tool 510 slightly toward the tire working surface, thus increasing the cutting depth. When shallow cutting is required, rotating the second stud 52 in the opposite direction causes the connecting stud 53 to rotate slightly, thereby moving the bearing plate 56 slightly downward. This causes the cutting tool 510 to move slightly in the opposite direction toward the tire working surface, thus decreasing the cutting depth. During the slight up-and-down movement of the bearing plate 56, the spring 58 can provide elastic buffering and reset, keeping the cutting tool 510 under relatively stable contact pressure.
[0053] The pressure block 44 serves as a mounting base to support the pressure roller 45, allowing the pressure roller 45 to roll and abut against the surface of the tire to form a support surface. The abutment wheel 28 mainly guides and limits the tire from both sides, while the pressure roller 45 provides support to the tire after machining. This allows the assembly mechanism 2 and the pressure mechanism 4 to cooperate with each other to support the tire.
[0054] During the use of the device, when the motor 31 drives the rotating shaft 32 to rotate, it will simultaneously drive the driven column 61 to rotate, thereby causing the collision block 62 to rotate. When the collision block 62 rotates to a specified angle, it contacts the contact block 63. During the contact between the collision block 62 and the contact block 63, the contact block 63 can be driven to slide horizontally. When the collision block 62 no longer contacts the contact block 63, another collision block 62 contacts the corresponding contact block 63, thereby driving the contact block 63 to slide in the opposite direction. Through the reciprocating sliding of the contact block 63, the sliding rod 64 can be driven to slide simultaneously, thereby driving the sliding plate 66 to slide, thereby driving the cleaning column 67 to slide synchronously. Through the contact cleaning column 67 to clean the tire area to be processed, the dust, impurities and oil stains accumulated on the surface of the tire during use can be wiped away, preventing dust and impurities from embedding into the cutting tool during cutting, which would cause surface scratches between the tire and the working surface.
[0055] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended description and its equivalents.

10. A method of using an online repair device for ball mill belts, comprising using the online repair device for ball mill belts as described in any one of claims 1-9, characterized in that, The method includes the following steps: The device is constructed with a first crossbar (1) and a second crossbar (7) forming the main support body. When assembling the device, the connecting rod (23) is placed inside the first crossbar (1). The positions of the upright block (21), the connecting rod (23) and the first crossbar (1) are fixed by rotating the first stud (22). The positions of the first fixing block (24) and the first crossbar (1) are then fixed by rotating the first stud (22). Finally, the positions of the first fixing rod (25) and the mounting plate (26) are fixed. When using the device, place it at the bottom of the tire. When the tire rotates, it will drive the abutment wheel (28) to rotate inside the fixed plate (27). The rotation of the abutment wheel (28) completes the positioning and support of the tire. Start the motor (31). The motor (31) drives the rotating shaft (32) to rotate, which in turn drives the driven shaft (34) to rotate through the belt (33), which in turn drives the screw (35) to rotate. The rotation of the screw (35) causes the sliding block (36) to drive the bearing block (38) to move horizontally. While sliding in the direction, the blade (510) set at the top of the support block (38) abuts against the bottom end of the tire. As the tire rotates, the raised area of the tire contacts the blade (510) for cutting. The uneven part is removed by contact cutting, thereby restoring the tire to a complete circle and a flat surface. In addition, the horizontal sliding of the support block (38) causes the blade (510) to move along the width of the tire, so as to achieve the repair of the entire width of the tire. The cutting depth can be adjusted by fine-tuning the feed mechanism (5). Specifically, when deep machining is required, the second stud (52) is rotated to drive the connecting column (53) to move slightly inside the first mounting block (51), so that the rotating column (54) drives the rotating plate (55) to rotate slightly around the outside of the bearing plate (56) as the axis, thereby pushing the bearing plate (56) to extend slightly, and thus the second mounting block (59) drives the blade (510) to move slightly towards the tire working surface, thereby increasing the cutting depth. When shallow cutting is required, the second stud (52) is rotated in the opposite direction, so that the connecting column (53) drives the rotating plate (55) to rotate slightly, thereby causing the bearing plate (56) to move slightly downward, and thus causing the blade (510) to move slightly in the opposite direction to the tire working surface, thereby decreasing the cutting depth. During the slight up and down movement of the bearing plate (56), the spring (58) can provide elastic buffering and reset, so that the blade (510) maintains a relatively stable contact pressure. The pressure block (44) serves as the mounting base to support the pressure roller (45), allowing the pressure roller (45) to roll and abut against the surface of the tire and form a supporting surface. The abutting wheel (28) mainly guides and limits the tire from both sides, while the pressure roller (45) provides support to the tire after machining. This allows the assembly mechanism (2) and the pressure mechanism (4) to cooperate with each other to support the tire. During the use of the device, when the motor (31) drives the rotating shaft (32) to rotate, it will simultaneously drive the driven column (61) to rotate, thereby causing the collision block (62) to rotate. When the collision block (62) rotates to a specified angle, it contacts the contact block (63). During the contact between the collision block (62) and the contact block (63), the contact block (63) can be driven to slide horizontally. When the collision block (62) no longer contacts the contact block (63), another collision block (62) contacts the corresponding contact block (63), thereby driving the contact block (63) to slide in the opposite direction. Through the reciprocating sliding of the contact block (63), the sliding rod (64) can be driven to slide, thereby driving the sliding plate (66) to slide, thereby driving the cleaning column (67) to slide synchronously. Through the contact cleaning column (67) to clean the tire area to be processed, the dust, impurities and oil stains accumulated on the surface of the tire during use can be wiped away, preventing dust and impurities from embedding into the cutting tool during cutting, causing surface scratches between the tire and the working surface.
