Description

Technical Field

[0001] This utility model belongs to the technical field of rubber roller grinding equipment, specifically a rubber roller grinding and polishing device resistant to strong acids. Background Technology

[0002] In many industrial fields such as chemical, electroplating, and pharmaceutical, the processes of material conveying, coating, and rolling in strong acid environments often rely on strong acid resistant rubber rollers. These rubber rollers are in contact with strong acid media for a long time, and their surfaces are easily corroded and worn, resulting in problems such as surface pits, hardened layer accumulation, and impurity adhesion.

[0003] Traditional methods of processing rubber rollers are often rudimentary, relying heavily on manual hand-held tools for polishing. This approach is not only inefficient and unsuitable for large-scale industrial production, but also highly dependent on the operator's experience, resulting in inconsistent quality. Furthermore, the lack of professional protection and precise process control makes the rubber rollers highly susceptible to secondary damage during polishing, further shortening their lifespan.

[0004] With the acceleration of industrial automation, the requirements for the surface quality of acid-resistant rubber rollers are becoming increasingly stringent. On the one hand, even minor defects on the surface of the rubber roller can lead to uneven material transmission, affecting the consistency and quality of products. For example, in the field of high-precision printing, unevenness on the surface of the rubber roller can directly cause blurry printed patterns and color deviations. On the other hand, the corrosive effect of the strong acid environment on the equipment causes frequent failures of conventional grinding equipment, resulting in high maintenance costs and long downtime, which seriously restricts production efficiency.

[0005] Existing general-purpose rubber roller polishing devices do not fully consider the special characteristics of strong acid conditions. They are made of ordinary metals or plastics, which are prone to rusting and deformation in strong acid environments, and cannot provide durable and reliable protection for internal precision mechanical structures. At the same time, the polishing power, adjustment mechanism and buffer protection design of these devices are simple and crude, making it difficult to achieve efficient, precise and non-destructive polishing of acid-resistant rubber rollers. They cannot meet the complex, ever-changing and high-standard production needs of modern industry. Therefore, it is urgent to develop a polishing device specifically for acid-resistant rubber rollers. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a strong acid resistant rubber roller polishing device. This device solves the technical problem that some existing general-purpose rubber roller polishing devices do not fully consider the special characteristics of strong acid conditions. Their materials are ordinary metals or plastics, which are prone to rusting and deformation in strong acid environments, and cannot provide durable and reliable protection for internal precision mechanical structures.

[0007] The present invention provides a polishing device for a strong acid-resistant rubber roller, comprising a polishing box. The polishing box is slidably connected to a mounting frame, which is driven by a power device. Two sets of mounting plates are slidably connected to the polishing box. A buffer assembly that cooperates with the mounting plates is provided on the polishing box. A polishing wheel is rotatably connected between the two sets of mounting plates, and the polishing wheel is connected by a drive device. Two sets of adjusting plates are slidably connected to the mounting frame. Each set of adjusting plates is provided with a bearing. A rubber roller is provided between the two sets of bearings. An adjusting assembly is provided on the mounting frame to adjust the distance between the two sets of adjusting plates.

[0008] Preferably, the power device includes a lead screw and a guide rod. The lead screw is rotatably connected to one side wall of the grinding box, and the guide rod is fixedly connected to the other side wall of the grinding box. The mounting bracket is threadedly connected to the lead screw and slidably connected to the guide rod. A first motor is fixedly connected to the grinding box, and the lead screw is driven by the first motor.

[0009] Preferably, the buffer assembly includes a damping rod and a shock-absorbing spring, and the damping rod and shock-absorbing spring are provided between the grinding box and the mounting plate.

[0010] Preferably, the driving device includes a second electric motor fixedly connected to one of the mounting plates, and the grinding wheel is driven by the second electric motor.

[0011] Preferably, the adjustment assembly includes a bidirectional screw, the mounting bracket is rotatably connected to the bidirectional screw, both sets of adjustment plates are threadedly connected to the bidirectional screw, and one end of the bidirectional screw is provided with an adjustment handle.

[0012] Preferably, the core layer of the grinding wheel is a hard matrix made of high-purity diamond particles sintered together, the middle layer is a mixture of nano-rubber particles and metal fibers, and the outer layer is coated with a strong acid-resistant ceramic coating.

[0013] Beneficial effects:

[0014] I. Precise and Efficient Grinding: This device is equipped with a mounting frame driven by a power unit and a grinding wheel rotatably connected to the mounting plate. The lead screw and guide rod in the power unit work together to enable the mounting frame to slide precisely and smoothly in the grinding box, ensuring that the relative position between the grinding wheel and the rubber roller is accurately controllable. Driven by the lead screw by the first motor, the cutting depth and grinding trajectory of the grinding wheel can be flexibly adjusted according to the size and wear condition of the rubber roller, realizing automated and high-precision grinding. Compared with traditional manual grinding, the efficiency is increased by several times or even dozens of times.

[0015] The bidirectional screw adjustment assembly is used to adjust the distance between the two sets of adjustment plates, thereby adapting to rubber rollers of different diameters. It is easy to operate; simply turn the adjustment handle to quickly fix the rubber roller in the appropriate position, ensuring that the rubber roller is always in a centrally symmetrical state during the grinding process. This avoids uneven surface quality caused by eccentric grinding and further improves grinding accuracy.

[0016] II. Powerful Grinding and Roller Protection: The grinding wheel adopts a unique three-layer structure design. The core layer is a hard matrix made of high-purity diamond particles sintered together, giving the grinding wheel super cutting power and the ability to quickly break through the hardened layer and corrosion on the surface of the rubber roller. The middle layer is a mixture of nano-rubber particles and metal fibers, which acts as a buffer and shock absorber, effectively absorbing high-frequency vibrations during the grinding process and preventing vibrations from being transmitted to the rubber roller and causing additional damage. The outer layer is wrapped with a strong acid-resistant ceramic coating, which not only resists strong acid corrosion, but also extends the service life of the grinding wheel itself, ensuring stable grinding over a long period of time and reducing the cost and time consumption caused by frequent grinding wheel replacements.

[0017] III. Stable Operation and Protection: The buffer assembly between the grinding chamber and the mounting plate includes damping rods and shock-absorbing springs. During the grinding process, when encountering uneven surfaces on the rubber rollers or sudden changes in material hardness, the buffer assembly can absorb the impact force in a timely manner, preventing damage to the mounting plate and grinding wheels from rigid impacts. This ensures the stability and reliability of the device, reduces equipment failure rate, decreases maintenance frequency, and improves production continuity. The grinding chamber provides a closed working environment for the entire grinding process, effectively blocking the diffusion of harmful substances such as strong acid mist and dust, protecting the internal precision mechanical structure from corrosion, extending the overall lifespan of the equipment, and reducing pollution to the surrounding working environment, thus meeting the requirements of modern industrial safety production and environmental protection.

[0024] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figure 1-5 The detailed description of the embodiments will clearly demonstrate this. All structural details mentioned in the following embodiments are based on the accompanying drawings.

[0025] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0026] Example 1: A strong acid resistant rubber roller polishing device includes a polishing box 1. The polishing box 1 is slidably connected to a mounting frame 2, which is driven by a power device. The polishing box 1 is slidably connected to two sets of mounting plates 3. The polishing box 1 is provided with a buffer assembly that cooperates with the mounting plates 3. A polishing wheel 4 is rotatably connected between the two sets of mounting plates 3, and the polishing wheel 4 is connected by a drive device. The mounting frame 2 is slidably connected to two sets of adjusting plates 5. Each set of adjusting plates 5 is provided with a bearing 6, and a rubber roller 7 is provided between the two sets of bearings 6. The mounting frame 2 is provided with an adjusting assembly to adjust the distance between the two sets of adjusting plates 5.

[0027] As an optional embodiment of Example 1, the power device includes a lead screw 8 and a guide rod 9. The lead screw 8 is rotatably connected to one side wall of the grinding box 1, and the guide rod 9 is fixedly connected to the other side wall of the grinding box 1. The mounting bracket 2 is threadedly connected to the lead screw 8 and slidably connected to the guide rod 9. A first motor 10 is fixedly connected to the grinding box 1, and the lead screw 8 is driven by the first motor 10.

[0028] As an optional embodiment of Example 1, the buffer assembly includes a damping rod 11 and a shock-absorbing spring 12, and the damping rod 11 and the shock-absorbing spring 12 are provided between the grinding box 1 and the mounting plate 3.

[0029] As an optional embodiment of Example 1, the driving device includes a second motor 13 fixedly connected to one of the mounting plates 3, and the grinding wheel 4 is driven by the second motor 13.

[0030] As an optional embodiment of Example 1, the adjustment assembly includes a bidirectional screw 14, the mounting bracket 2 is rotatably connected to the bidirectional screw 14, both sets of adjustment plates 5 are threadedly connected to the bidirectional screw 14, and one end of the bidirectional screw 14 is provided with an adjustment handle 15.

[0031] As an optional embodiment of Example 1, the core layer of the grinding wheel 4 is a hard matrix made of high-purity diamond particles sintered together, the middle layer is a mixture of nano-rubber particles and metal fibers, and the outer layer is wrapped with a strong acid resistant ceramic coating.

[0032] When using it, first prepare all the parts. The grinding box 1 is made of a special alloy material that is resistant to strong acids to ensure that it has good corrosion resistance in a strong acid environment. The lead screw 8 is rotatably connected to one side wall of the grinding box 1 through the bearing seat to ensure that the lead screw 8 can rotate flexibly. At the same time, the guide rod 9 is firmly fixed to the other side wall of the grinding box 1 to ensure that the guide rod 9 and the lead screw 8 are parallel to each other, so as to provide guidance for the smooth movement of the mounting frame 2.

[0033] Connect the mounting bracket 2 to the lead screw 8 with a thread so that it can slide precisely along the direction of the guide rod 9 when the lead screw 8 rotates. Then, fix the first motor 10 on the grinding box 1 and connect the output shaft of the first motor 10 to the lead screw 8 through a coupling to ensure that the power can be transmitted stably and drive the mounting bracket 2 to move.

[0034] Two sets of mounting plates 3 are installed inside the grinding box 1, so that the mounting plates 3 can slide smoothly on the guide rails on the inner wall of the grinding box 1. A damping rod 11 and a shock-absorbing spring 12 are installed between the grinding box 1 and the mounting plate 3. One end of the damping rod 11 is fixed on the grinding box 1, and the other end is connected to the mounting plate 3. The shock-absorbing spring 12 is sleeved on the outside of the damping rod 11, and its two ends abut against the grinding box 1 and the mounting plate 3 respectively, forming a buffer assembly to effectively buffer the impact force during the grinding process.

[0035] The second motor 13 is fixedly mounted on one of the mounting plates 3, and its output shaft is connected to the grinding wheel 4 via a coupling to ensure that the grinding wheel 4 can rotate at high speed and smoothly under the drive of the second motor 13. According to design requirements, the grinding wheel 4 adopts a special structure with a core layer of a hard matrix made of high-purity diamond particles sintered together, a middle layer of a mixture of nano-rubber particles and metal fibers, and an outer layer of a strong acid-resistant ceramic coating, ensuring both grinding performance and strong acid resistance.

[0036] Two sets of adjusting plates 5 are installed on the mounting frame 2 via a guide rail structure, allowing them to slide relative to each other on the mounting frame 2. The bidirectional screw 14 is rotatably connected to the mounting frame 2, ensuring that the two threads of the bidirectional screw 14 rotate in opposite directions. The two sets of adjusting plates 5 are threadedly connected to the two threads of the bidirectional screw 14 respectively. An adjusting handle 15 is installed at one end of the bidirectional screw 14 for easy manual adjustment by the operator. Bearings 6 are installed on both sets of adjusting plates 5. The bearings 6 are made of acid-resistant material and are used to support the rubber roller 7, ensuring that the rubber roller 7 can rotate flexibly.

[0037] Workflow

[0038] I. Preparation Stage: Operators should wear protective equipment, including acid-resistant gloves and goggles, to ensure their safety. Open the door of the grinding chamber 1 and move the acid-resistant rubber roller 7 to be ground and polished to the vicinity of the mounting frame 2. According to the diameter of the rubber roller 7, turn the adjusting handle 15 to drive the two sets of adjusting plates 5 to move relative to each other through the double-acting screw 14, so that the rubber roller 7 can be placed precisely between the bearings 6 on the two sets of adjusting plates 5, and ensure that the rubber roller 7 is in a horizontal state. Then gently rotate the rubber roller 7 to check whether its rotation is flexible. Close the door of the grinding chamber 1 to ensure that the door is well sealed to prevent the leakage of strong acid mist. The door of the grinding chamber 1 is not a necessary technical feature, and the door can be omitted, and the equipment can be placed in a closed working environment for grinding.

[0039] II. Grinding Stage: Start the first motor 10, which drives the lead screw 8 to rotate, thereby driving the mounting bracket 2 to slowly move along the guide rod 9 towards the grinding wheel 4, so that the grinding wheel 4 gradually approaches the rubber roller 7. At the same time, start the second motor 13, which drives the grinding wheel 4 to rotate at high speed. When the grinding wheel 4 contacts the surface of the rubber roller 7, the speed of the first motor 10 is adjusted by the control system (which can be connected to an external control panel or a preset program) according to the wear condition of the rubber roller 7, the hardness of the material, and the required grinding precision. This controls the relative feed speed between the grinding wheel 4 and the rubber roller 7. For example, when grinding the hardened layer on the surface of the rubber roller 7, the feed speed can be appropriately slowed down to 0.5-1 mm / s. When performing surface finishing, the feed speed can be increased to 1-2 mm / s.

[0040] During the grinding process, if the surface of the rubber roller 7 is uneven or the material hardness changes abruptly, the mounting plate 3 will be subjected to impact force. At this time, the damping rod 11 and the shock-absorbing spring 12 in the buffer assembly will immediately play their role. The damping rod 11 restricts the excessive displacement of the mounting plate 3, and the shock-absorbing spring 12 absorbs the impact force, preventing damage to the grinding wheel 4 and the mounting plate 3, and ensuring the smooth progress of the grinding process.

[0041] III. Polishing Stage: After the grinding process is completed and the predetermined surface roughness requirement is achieved, the first motor 10 is stopped, so that the grinding wheel 4 and the rubber roller 7 are relatively stationary. The grinding wheel 4 is replaced with a polishing wheel (if the grinding wheel 4 has a polishing function, the working mode can be switched directly). The polishing wheel is also made of acid-resistant material and has fine polishing texture on the surface.

[0042] Restart the first motor 10, adjust the moving speed of the mounting bracket 2 so that it drives the rubber roller 7 to contact the polishing wheel at a slower speed, and at the same time start the drive motor connected to the polishing wheel (similar to the setting of the second motor 13) to drive the polishing wheel to rotate at an appropriate speed, such as 300-500 rpm, to finely polish the surface of the rubber roller 7 so that the surface of the rubber roller 7 achieves a mirror effect.

[0043] IV. Final Stage: After polishing is completed, stop all motors in sequence, including the first motor 10, the second motor 13 and the polishing wheel drive motor. Open the door of the grinding box 1, take out the polished rubber roller 7, and check the surface quality of the rubber roller 7 to see if it has achieved the expected polishing effect, such as whether the surface roughness, gloss and other indicators meet the requirements.

[0044] Clean and maintain the device, removing debris, residual strong acid solution and other impurities from the grinding chamber 1, and checking the wear of each component, such as the wear of the grinding wheel 4 and bearing 6. Replace any components that need to be replaced in a timely manner to ensure that the device can operate normally next time.

[0045] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
