Description

Technical Field

[0001] This invention relates to the field of rubber roller polishing technology, and in particular to a follow-up polishing device for repairing the outer circle of a rubber roller. Background Technology

[0002] Rubber rollers are core functional roller components in industrial production. They typically use high-strength metal as a rigid core shaft, with an outer layer of natural or synthetic rubber, and are produced as cylindrical components with different hardnesses and surface structures through vulcanization. They are widely used in printing, papermaking, textiles, rubber and plastics processing, metallurgy, packaging and other industrial fields, undertaking key processes such as material conveying, calendering, coating, bonding, traction and embossing. The geometric accuracy, roundness, surface roughness and coaxiality of their outer cylindrical surface determine the stability of the production process, the processing accuracy of the product and the quality of the finished product. However, long-term operation can lead to performance degradation due to wear, corrosion and deformation. Therefore, it is necessary to restore their surface accuracy and working performance through outer cylindrical repair and grinding. They are key wear parts that ensure the efficient and stable operation of industrial production lines.

[0003] Currently, during the grinding process of rubber rollers, the rigid and continuous contact between the grinding wheel and the rubber roller generates a continuous lateral resistance force on the soft rubber roller body, which can easily cause damage such as local deformation of the roller body, roller detachment, or even burns and blistering. This cannot meet the repair requirements of high-precision rubber rollers. Furthermore, the sticky rubber debris generated during grinding not only splashes everywhere, polluting the working environment and adhering to the inside of the equipment, affecting operational stability, but also easily clogs the grinding wheel pores, causing the grinding wheel to become dull and grinding efficiency to drop sharply. There is a general lack of integrated debris collection and grinding wheel self-cleaning mechanisms, requiring frequent machine shutdowns for manual cleaning, which significantly reduces the overall efficiency of rubber roller repair, increases manual maintenance costs, and causes poor process continuity due to work interruptions, making it difficult to adapt to the core requirements of modern industrial production lines for high-precision, low-damage, and continuous repair.

[0004] To address the aforementioned technical deficiencies, a solution is proposed that uses a dual fixation mechanism of conical grooves and clamping claws to center and hold the rubber roller. Combined with intermittent contact grinding of the triangular arc-shaped abrasive blocks of the grinding wheel, this avoids deformation damage to the rubber roller, achieving low-damage follow-up grinding. Simultaneously, a negative pressure collection and self-cleaning mechanism is integrated to collect grinding debris in a directional manner and blow it back onto the grinding wheel with a clean airflow, achieving fully automatic sand cleaning and heat dissipation. This forms an integrated process of grinding, chip removal, and sand cleaning, ensuring stable grinding quality and improving work efficiency and grinding wheel lifespan. Summary of the Invention

[0005] The purpose of this invention is to provide a follow-up grinding device for repairing the outer circle of a rubber roller, in order to solve the aforementioned technical defects.

[0006] The objective of this invention can be achieved through the following technical solution: a follow-up grinding device for repairing the outer circle of a rubber roller, comprising a support platform, wherein the support platform is provided with two sets of rotating clamping components for centering and clamping the rubber roller, and a grinding component for repairing and grinding the outer circle of the rubber roller and having a self-cleaning mechanism.

[0007] The rotary clamping assembly includes two sets of clamping discs, each with a tapered groove on its opposite side, and clamping claws located on both sides of the clamping discs that move relative to each other as the clamping discs move.

[0008] The grinding assembly includes a collection shell and an electric push rod for horizontal movement of the collection shell. A rotating cylinder is rotatably installed inside the collection shell, and a grinding wheel is fixedly installed on the outer wall of the rotating cylinder. A triangular arc-shaped sand block is provided on the annular outer wall of the grinding wheel.

[0009] The top of the support platform is slidably connected to two sets of movable frames via slide rails, and a rotating seat that is slidably connected to the clamping claw is rotatably mounted on the movable frame. A guide rod that is slidably connected to the rotating seat is fixedly connected to the clamping plate. A spring is fixedly connected between the clamping plate and the rotating seat. A connecting rod is hinged between the clamping claw and the clamping plate. A motor that drives the corresponding rotating seat to rotate is installed on the movable frame via bolts.

[0010] Preferably, the triangular arc-shaped sand blocks are integrally formed with the grinding wheel, and there are two sets of them distributed at equal intervals on the arc-shaped outer wall of the grinding wheel. An inclined guide surface is provided at the end face edge of the grinding wheel.

[0011] Preferably, a second motor is bolted to the bottom of the support platform, and a gear is fixedly mounted on the output shaft of the second motor. Both sets of moving frames are fixedly mounted with staggered toothed plates, and the two sets of toothed plates mesh with the gears.

[0012] Preferably, a movable bracket is slidably connected to the top of the support platform via a slide rail, the electric push rod is fixedly installed on the movable bracket, a support rod slidably connected to the movable bracket is fixedly connected to the collecting shell, a lead screw threadedly connected to the movable bracket is rotatably installed on the top of the support platform, and a motor for driving the lead screw to rotate is installed on the support platform via bolts.

[0013] Preferably, a motor for driving the rotating cylinder is bolted to the collection shell, and a blower is rotatably connected inside the rotating cylinder, with an air outlet slit extending through the bottom of the blower. The rotating cylinder has a mesh cylinder structure.

[0014] Preferably, the bottom of the collection shell is fixedly connected to a suction pipe, and the free end of the suction pipe is fixedly connected to a filter box by bolts.

[0015] Preferably, the blower is provided on the blower pipe, and a filter screen and filter cotton are installed inside the filter box and between the air inlet of the suction pipe and the air inlet of the blower pipe, with the filter screen located above the filter cotton.

[0016] The beneficial effects of this invention are as follows:

[0017] (1) This invention uses a dual fixing method of conical groove centering contact and linkage clamping claw to achieve self-centering of the rubber roller shaft during the clamping stage, eliminating common problems such as clamping eccentricity and axial movement, and providing a stable reference for grinding. At the same time, the triangular arc-shaped abrasive blocks on the outer wall of the grinding wheel form intermittent contact with the outer circle of the rubber roller when the grinding wheel rotates. On the one hand, this avoids the lateral resistance caused by the continuous rigid contact between the traditional grinding wheel and the rubber roller, and avoids damage such as deformation and roll detachment of the rubber roller. On the other hand, it adopts a progressive grinding depth method to provide stable grinding contact force and simultaneously maintain the smoothness of the outer circle of the roller after grinding, so as to achieve low damage and high precision outer circle repair of soft rubber roller. Combined with the horizontal feed of the electric push rod, the horizontal movement of the moving bracket, and the rotation of the rubber roller, the grinding wheel can achieve full-area coverage follow-up grinding repair of the outer circle of the rubber roller.

[0018] (2) The present invention also adopts a combination of negative pressure collection and active blowing. Rubber debris in the grinding area is extracted by directional negative pressure airflow and filtered and intercepted by the filter box to achieve centralized collection of debris, solving the problem of rubber grinding debris splashing everywhere and polluting the working environment. At the same time, the filtered clean airflow is directed to the inside of the rotating cylinder and blows the surface of the triangular arc-shaped sand block from the inside out to achieve efficient self-cleaning of the grinding wheel surface, effectively removing rubber impurities embedded in the grinding wheel pores, and performing efficient heat dissipation treatment on the grinding wheel to prevent debris from melting and adhering, eliminating problems such as grinding wheel passivation and reduced grinding efficiency, forming a continuous and efficient grinding operation cycle, extending the service life of the grinding wheel, ensuring the stability of grinding quality, eliminating the need for additional machine shutdown for cleaning, and improving the work efficiency of rubber roller repair.

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

[0032] Example 1: Please refer to Figure 1 - Figure 5 and Figure 7 As shown, the problem that the rigid and continuous contact between the grinding wheel and the rubber roller will generate a continuous lateral resistance force on the soft rubber roller body, which can easily cause local deformation of the roller body, roll detachment, or even burns and blistering, can be solved by the following solutions;

[0033] This embodiment of a follow-up grinding device for repairing the outer circle of a rubber roller includes a support platform 1. The support platform 1 is provided with two sets of rotating clamping assemblies for centering and clamping the rubber roller, and a grinding assembly for repairing and grinding the outer circle of the rubber roller with a self-cleaning mechanism. The rotating clamping assembly includes two sets of clamping disks 2, and each clamping disk 2 has a conical groove 21 on its opposite side, and clamping claws 22 located on both sides of the clamping disk 2 that move relative to each other as the clamping disk 2 moves. The device uses the dual fixation of the conical groove 21 for centering and the clamping claws 22 for auxiliary clamping to achieve self-centering of the rubber roller shaft during the clamping stage, eliminating common problems such as clamping eccentricity and axial movement, and providing a stable reference for grinding.

[0034] The grinding assembly includes a collection shell 3 and an electric push rod 31 for horizontal movement of the collection shell 3. A rotating cylinder 32 is rotatably installed inside the collection shell 3, and a grinding wheel 33 is fixedly installed on the outer wall of the rotating cylinder 32. A triangular arc-shaped sand block 34 is provided on the annular outer wall of the grinding wheel 33. The electric push rod 31 pushes the collection shell 3 to move, causing the triangular arc-shaped sand block 34 to contact the rubber roller, and the outer wall of the grinding wheel 33 cannot contact the rubber roller.

[0035] At this time, during the high-speed rotation of the grinding wheel 33, the triangular arc-shaped abrasive block 34 intermittently contacts the rubber roller through circumferential rotation, avoiding the continuous application of lateral resistance to the rubber roller, which could cause slight deformation of the roller body or the problem of roller detachment. At the same time, by taking advantage of the triangular characteristics of the triangular arc-shaped abrasive block 34, the grinding depth is gradually increased to provide a stable grinding contact force and simultaneously maintain the smoothness of the outer circle of the roller after grinding.

[0036] The triangular arc-shaped abrasive blocks 34 are integrally formed with the abrasive wheel 33, and there are two sets of them, which are equally distributed on the arc-shaped outer wall of the abrasive wheel 33. They are used to maintain the stability of the abrasive wheel 33 during rotation and avoid the problem of limited grinding accuracy caused by the abrasive wheel 33 swaying. An inclined guide surface is provided at the end face edge of the abrasive wheel 33. When the abrasive wheel 33 moves along the axis of the rubber roller for grinding, it can achieve a large-area contact between the rubber roller and the abrasive wheel 33. This avoids the problem of excessive heat concentration during grinding, which leads to inadequate heat dissipation and rapid melting and adhesion of debris and impurities.

[0037] The top of the support platform 1 is slidably connected to two sets of movable frames 23 via slide rails, and a rotating seat 24 that is slidably connected to the clamping claw 22 is rotatably mounted on the movable frame 23. A guide rod that is slidably connected to the rotating seat 24 is fixedly connected to the clamping plate 2. A spring 25 is fixedly connected between the clamping plate 2 and the rotating seat 24. A connecting rod 26 is hinged between the clamping claw 22 and the clamping plate 2.

[0038] The rubber roller is placed between two sets of clamping discs 2, and the two sets of moving frames 23 slide relative to each other, causing the conical groove 21 on the clamping disc 2 to abut against the roller shaft of the rubber roller. With the abutment of the conical groove 21 against the roller shaft of the rubber roller, the rubber roller is centered and clamped at a fixed height along the axis. During the clamping process, with the abutment of the clamping disc 2 against the rubber roller, the clamping disc 2 moves relative to the moving frame 23. The clamping disc 2, combined with the connecting rod 26, drives the clamping claws 22 on both sides to clamp the roller shaft of the rubber roller, thereby stabilizing and fixing the rubber roller by abutting against the roller shaft at both ends and assisting in secondary clamping.

[0039] The guide rod and connecting rod 26 are used to limit the stable horizontal movement of the clamping plate 2. The spring 25 is used to assist the clamping plate 2 and the linkage clamping claw 22 in resetting movement after the rubber roller is unloaded. The moving frame 23 is equipped with a motor that drives the corresponding rotating seat 24 to rotate by bolts. The rotating grinding wheel 33 moves horizontally, and the motor drives the rotating seat 24 to slowly rotate the rubber roller. The rotation direction of the rubber roller is the same as that of the grinding wheel 33, thereby performing a comprehensive outer circle repair and grinding treatment on the annular outer wall of the rubber roller.

[0040] The bottom of the support platform 1 is bolted with a motor 2, and a gear 11 is fixedly installed on the output shaft of the motor 2. Both sets of moving frames 23 are fixedly installed with staggered toothed plates 27, and the two sets of toothed plates 27 mesh with the gear 11. The motor 2 drives the gear 11 to rotate, and the gear 11 meshes with the two sets of toothed plates 27 to drive the two sets of moving frames 23 to slide synchronously relative to each other or away from each other.

[0041] A movable bracket 35 is slidably connected to the top of the support platform 1 via a slide rail. An electric push rod 31 is fixedly installed on the movable bracket 35. A support rod that is slidably connected to the movable bracket 35 is fixedly connected to the collection shell 3. A lead screw 12 that is threadedly connected to the movable bracket 35 is rotatably installed on the top of the support platform 1. A motor 3 that drives the lead screw 12 to rotate is installed on the support platform 1 via bolts. The motor 3 drives the lead screw 12 to rotate, and the lead screw 12 drives the movable bracket 35 to move horizontally carrying the rotating grinding wheel 33.

[0042] Example 2: Please refer to Figure 5 and Figure 6 As shown, the sticky rubber debris generated during grinding not only flies everywhere, polluting the working environment and adhering to the inside of the equipment, affecting operational stability, but also easily clogs the grinding wheel pores, causing grinding wheel dulling and a sharp drop in grinding efficiency. The following solutions can be used to address these issues.

[0043] In this embodiment, a motor 4 that drives the rotating cylinder 32 to rotate is installed on the collection shell 3 by bolts. The inside of the rotating cylinder 32 is rotatably connected to the air blower 36, and the bottom of the air blower 36 is provided with an air outlet slit 37. The rotating cylinder 32 has a mesh cylinder structure. During the grinding process, air is blown into the air blower 36 and then blown from the air outlet slit 37 to the lower inner wall of the rotating cylinder 32 and into the grinding wheel 33, thereby blowing out the impurities embedded on the surface of the grinding wheel 33 in the opposite direction.

[0044] It achieves efficient self-cleaning of the grinding wheel 33 surface, effectively removes rubber impurities embedded in the pores of the grinding wheel 33, and provides efficient heat dissipation treatment for the grinding wheel 33 to prevent debris from melting and adhering. It eliminates problems such as grinding wheel 33 passivation and reduced grinding efficiency, forming a continuous and efficient grinding operation cycle, extending the service life of the grinding wheel 33, ensuring the stability of grinding quality, eliminating the need for additional machine downtime for cleaning, and improving the efficiency of rubber roller repair.

[0045] The bottom of the collection shell 3 is fixedly connected to a suction pipe 38, and the free end of the suction pipe 38 is fixedly connected to a filter box 39 by bolts. The filter box 39 and the blower 36 are fixedly connected by a blower pipe 310, and the blower pipe 310 is fixedly connected to the collection shell 3. The rubber debris in the grinding area is extracted by the directional negative pressure airflow of the suction pipe 38 and filtered and intercepted by the filter box 39, so as to realize the centralized collection of debris and solve the problem of rubber grinding debris flying everywhere and polluting the working environment.

[0046] A blower is installed on the blower pipe 310. Inside the filter box 39, between the air intake pipe 38 and the air inlet of the blower pipe 310, a filter screen and filter cotton are installed, with the filter screen located above the filter cotton. The blower extracts gas from the opening area of ​​the collection shell 3 located below the grinding wheel 33 through part of the blower pipe 310, the filter box 39, and the air intake pipe 38, thereby guiding and extracting the grinding debris. The debris is then collected into the filter box 39 through multiple barriers of the filter screen and filter cotton. The filtered gas is blown into the blower 36 through part of the blower pipe 310 to achieve a reverse blowing effect.

[0047] Example 3: Please refer to Figure 1 - Figure 7 As shown, the present invention also proposes a method for using a follow-up grinding device for repairing the outer diameter of a rubber roller, comprising the following steps:

[0048] Step 1: The rubber roller is placed between two sets of clamping discs 2. The motor drives the gear 11 to rotate. The gear 11 meshes with two sets of toothed plates 27, which drives the two sets of moving frames 23 to slide relative to each other. This causes the conical groove 21 on the clamping disc 2 to abut against the roller shaft of the rubber roller. With the help of the conical groove 21 against the roller shaft of the rubber roller, the rubber roller is centered and clamped at a fixed height along the axis. During the clamping process, with the help of the contact between the clamping disc 2 and the rubber roller, the clamping disc 2 moves relative to the moving frame 23. The clamping disc 2, combined with the connecting rod 26, drives the clamping claws 22 on both sides to clamp the roller shaft of the rubber roller. Thus, the rubber roller is stabilized and fixed by the self-centering contact at both ends and the auxiliary secondary clamping.

[0049] Step Two: The motor-driven rotating cylinder 32 carries the grinding wheel 33 to rotate at high speed. The electric push rod 31 pushes the collecting shell 3 to move horizontally towards the rubber roller, carrying the grinding wheel 33, until the triangular arc-shaped sand blocks 34 on the surface of the grinding wheel 33 contact the outer surface of the rubber roller to perform repair and grinding treatment on the outer surface. When the surface of the grinding wheel 33 does not contact the rubber roller, the electric push rod 31 stops pushing the collecting shell 3 to move. The motor-driven lead screw 12 rotates, and the lead screw 12 drives the moving bracket 35 to move horizontally carrying the rotating grinding wheel 33. Combined with the motor-driven rotating seat 24 carrying the rubber roller to rotate slowly, the direction of rotation of the rubber roller is the same as the direction of rotation of the grinding wheel 33, thereby performing comprehensive outer circle repair and grinding treatment on the outer wall of the rubber roller. By intermittently contacting the rubber roller through the circumferential rotation of the triangular arc-shaped sand blocks 34, the continuous lateral resistance force on the rubber roller is avoided, which could cause slight deformation of the roller or the problem of roller detachment. At the same time, the grinding depth is gradually increased to provide stable grinding contact force and maintain the smoothness of the outer circle of the roller after grinding.

[0050] Step 3: During the grinding process, the blower extracts gas from the opening area of ​​the collection shell 3 located below the grinding wheel 33 through part of the air blowing pipe 310, the filter box 39, and the suction pipe 38. This guides and extracts the grinding debris, which is then collected in the filter box 39 by the filter screen and filter cotton. The filtered gas is blown into the air blowing tube 36 through part of the air blowing pipe 310, and then blown from the air outlet slit 37 to the inner wall below the rotating cylinder 32, entering the interior of the grinding wheel 33. This blows out the impurities embedded on the surface of the grinding wheel 33. Combined with the extraction of external gas, this process collects the impurities while maintaining continuous and efficient grinding of the outer circle of the rubber roller by the grinding wheel 33.

[0051] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
