Description

Technical Field

[0001] This utility model belongs to the technical field of anilox roller processing equipment, and in particular relates to a grinding wheel surface structure for improving the surface quality of ceramic anilox rollers. Background Technology

[0002] Ceramic anilox rollers are widely used in industrial fields such as printing and coating. Their surface quality directly affects the accuracy and effect of printing and coating. Currently, the post-treatment of ceramic anilox rollers after the ceramic layer is sprayed usually adopts processes such as fine abrasive wheel grinding and subsequent polishing.

[0003] Existing technologies have many drawbacks. When grinding with fine abrasive wheels, the small size of the abrasive grains results in a large number of grains participating in the grinding process per unit time, leading to low grinding force and low processing efficiency. At the same time, the friction between the fine abrasive wheel and the ceramic surface is intense during grinding, causing the wheel to wear quickly and easily become clogged by grinding debris. This necessitates frequent wheel dressing, which not only increases processing costs but also prolongs the processing cycle. While using coarse abrasive wheels can improve grinding efficiency to some extent, the larger abrasive grains exert greater force on the surface of the ceramic anilox roller during grinding, increasing the depth of subsurface damage. This reduces the corrosion and wear resistance of the anilox roller, thus affecting its service life.

[0004] To address these issues, we provide a grinding wheel surface structure that improves the surface quality of ceramic anilox rollers. Utility Model Content

[0005] The purpose of this invention is to provide a grinding wheel surface structure that improves the surface quality of ceramic anilox rollers. By combining the grinding wheel body and the triple helical grooves, the invention solves the problems of low processing efficiency, rapid grinding wheel wear, frequent clogging, and poor grinding quality in the existing ceramic anilox roller grinding process.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a grinding wheel surface structure for improving the surface quality of ceramic anilox rollers. It includes a grinding wheel body with a triple helical groove on its surface. Mounting grooves are located at both the front and rear ends of the grinding wheel body. A heat-conducting plate is installed within the inner cavity of each mounting groove. A positioning seat is fixedly connected to the surface of the heat-conducting plate, and a positioning hole is provided within the inner cavity of the positioning seat. The helical tilt angle is adjusted according to the feed speed, allowing the grinding wheel surface structure to adapt to different processing requirements. When high processing efficiency is required, the helical tilt angle can be appropriately increased to improve cooling efficiency. When surface flatness is required... For applications requiring higher precision, a smaller helical tilt angle can be selected to ensure the quality of the ground surface. This flexibility allows the grinding wheel to better complement subsequent fine grinding and polishing processes, meeting the surface quality requirements of ceramic anilox rollers in different production scenarios. Compared to traditional grinding wheel surface processing techniques, the laser engraving method offers advantages such as simple operation, high processing precision, and short production cycle. It eliminates the need for complex molds and processing equipment, enabling rapid processing of triple helical grooves on the grinding wheel surface, reducing production costs, improving production efficiency, and facilitating its widespread application in actual production.

[0008] The present invention is further configured such that the depth of the triple helical groove is 0.005-0.01mm. The depth of the triple helical groove is set to 0.005-0.01mm. This depth range is optimized to ensure that the groove has enough space to accommodate grinding debris, improve the chip-holding capacity of the grinding wheel, and prevent chip accumulation from clogging the grinding wheel. At the same time, the groove is not too deep, which would weaken the structural strength of the grinding wheel and ensure the stability of the grinding wheel during high-speed rotation and grinding. The appropriate depth also ensures that air and grinding fluid can enter the grinding area smoothly, which can achieve good heat dissipation and cooling effect, maintain a low temperature in the grinding contact area, reduce thermal stress cracks, and ensure the surface quality of the ceramic anilox roller and the normal service life of the grinding wheel.

[0009] The present invention is further configured such that each of the four corners of the heat-conducting plate is threaded with a positioning pin, and the surface of the heat-conducting plate is provided with mounting holes for use with the positioning pins. The positioning pins are threadedly connected to the four corners of the heat-conducting plate and cooperate with the corresponding mounting holes and threaded holes on the grinding wheel body. This enables precise positioning and stable connection between the heat-conducting plate and the grinding wheel body. The positioning pins can effectively prevent the heat-conducting plate from shifting or loosening when the grinding wheel rotates at high speed, ensuring that the heat-conducting plate continuously and stably plays its heat-conducting role, quickly conducting away the heat generated during the grinding process, further reducing the temperature of the grinding wheel, and avoiding the degradation of grinding wheel performance and damage to the surface of the ceramic anilox roller caused by local overheating. The heat dissipation holes increase the contact area between the grinding wheel and the air, accelerating the air circulation inside the grinding wheel.

[0010] The present invention is further provided that the surface of the grinding wheel body is provided with heat dissipation holes, which are circumferentially distributed on the surface of the grinding wheel body. During the grinding process, air can carry away the heat inside the grinding wheel through the heat dissipation holes, forming a good heat dissipation channel. This works in conjunction with the heat dissipation effect of the three helical grooves to further reduce the overall temperature of the grinding wheel.

[0011] The present invention is further configured such that a threaded hole is provided on the surface of the grinding wheel body, the threaded hole being adapted to the positioning pin, and the threaded hole on the surface of the grinding wheel body being adapted to the positioning pin, so as to be able to fit tightly with the positioning pin on the heat-conducting plate and ensure the positioning accuracy during the installation of the heat-conducting plate.

[0012] The present invention is further provided that a circular hole is provided at the center of the grinding wheel body, the circular hole being adapted to the positioning hole. The circular hole facilitates the precise installation and positioning of the grinding wheel on the grinding equipment. By cooperating with the positioning components on the equipment, it can ensure that the grinding wheel maintains good concentricity during rotation, reduce vibration and wear caused by eccentricity, and improve the stability and accuracy of grinding.

[0013] The present invention has the following beneficial effects.

[0014] 1. This utility model increases the contact area between the grinding wheel surface and the air through the design of the triple spiral groove. During the grinding process, the air can enter the grinding contact area more smoothly, which plays a good role in heat dissipation and effectively reduces the temperature of the grinding contact area. At the same time, the presence of the groove allows the grinding fluid to reach the grinding area more quickly, further enhancing the cooling effect, reducing the generation of thermal stress cracks caused by high temperature, and improving the surface quality and service life of the ceramic anilox roller.

[0015] 2. This utility model provides a discharge channel for grinding chips through the three helical grooves. Compared with the traditional smooth grinding wheel surface, it can significantly improve the chip holding and removal capacity of the grinding wheel surface. The chips can be discharged in time along the helical grooves, avoiding accumulation on the grinding wheel surface, thereby effectively preventing the grinding wheel surface from clogging, reducing the number of grinding wheel dressing times, extending the service life of the grinding wheel, and improving processing efficiency.

[0023] The technical solutions of the present invention will be described below with reference to the accompanying drawings of the embodiments of the present invention. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Example 1

[0025] Please see Figure 1-5 This utility model is a grinding wheel surface structure for improving the surface quality of ceramic anilox rollers. It includes a grinding wheel body 1, a triple helical groove 2 on the surface of the grinding wheel body 1, a mounting groove 3 at both the front and rear ends of the grinding wheel body 1, a heat-conducting plate 4 in the inner cavity of the mounting groove 3, a positioning seat 5 fixedly connected to the surface of the heat-conducting plate 4, and a positioning hole 6 in the inner cavity of the positioning seat 5.

[0026] Specifically, the spiral tilt angle is adjusted according to the feed speed to adapt the surface structure of the grinding wheel to different processing requirements. When high processing efficiency is required, the spiral tilt angle can be appropriately increased to improve cooling efficiency. When high surface flatness is required, a smaller spiral tilt angle can be selected to ensure the grinding surface quality. This flexibility allows the grinding wheel to better cooperate with subsequent fine grinding and polishing processes, meeting the surface quality requirements of ceramic anilox rollers in different production scenarios. The processing method of direct engraving with a laser engraving machine has the advantages of simple operation, high processing accuracy, and short production cycle compared with traditional grinding wheel surface processing technology. It does not require complex molds and processing equipment, and can quickly realize the processing of triple spiral grooves on the grinding wheel surface, reducing production costs, improving production efficiency, and facilitating its promotion and application in actual production.

[0027] Example 2

[0028] Please see Figure 1-5Based on Example 1, the depth of the triple helical groove 2 is 0.005-0.01mm, and the four corners of the heat-conducting plate 4 are threaded with positioning pins 7. The surface of the heat-conducting plate 4 is provided with mounting holes 8 that cooperate with the positioning pins 7. The surface of the grinding wheel body 1 is provided with heat dissipation holes 9, which are distributed circumferentially on the surface of the grinding wheel body 1. The surface of the grinding wheel body 1 is provided with threaded holes 10, which are adapted to the positioning pins 7. The center of the grinding wheel body 1 is provided with a circular hole 11, which is adapted to the positioning hole 6.

[0029] Specifically: The depth of the triple helical groove 2 is set to 0.005-0.01mm. This depth range has been optimized to ensure that the groove has sufficient space to accommodate grinding debris, improving the chip-holding capacity of the grinding wheel and preventing chip accumulation that could clog it. At the same time, the groove is not too deep, which could weaken the structural strength of the grinding wheel and ensure its stability during high-speed rotation and grinding. The appropriate depth also ensures that air and grinding fluid can smoothly enter the grinding area, providing good heat dissipation and cooling, maintaining a low temperature in the grinding contact area, reducing thermal stress cracks, and ensuring the surface quality of the ceramic anilox roller and the normal service life of the grinding wheel. The four corners of the heat-conducting plate 4 are connected to locating pins 7 via threads, which mate with the corresponding mounting holes 8 and threaded holes 10 on the grinding wheel body 1. This ensures precise positioning and a stable connection between the heat-conducting plate 4 and the grinding wheel body 1. The locating pins 7 effectively prevent displacement or loosening of the heat-conducting plate 4 during high-speed rotation of the grinding wheel, ensuring the stability of the heat-conducting plate. 4. It continuously and stably plays a heat-conducting role, quickly transferring the heat generated during the grinding process, further reducing the grinding wheel temperature, and avoiding the degradation of grinding wheel performance and damage to the surface of the ceramic anilox roller caused by local overheating. The heat dissipation holes 9 increase the contact area between the grinding wheel and the air, accelerating the air circulation inside the grinding wheel. During the grinding process, the air can carry away the heat inside the grinding wheel through the heat dissipation holes 9, forming a good heat dissipation channel. This works in conjunction with the heat dissipation effect of the triple helical grooves 2 to further reduce the overall temperature of the grinding wheel. The grinding wheel body 1 has threaded holes 10 that are compatible with the positioning pins 7, which can fit tightly with the positioning pins 7 on the heat-conducting plate 4, ensuring the positioning accuracy of the heat-conducting plate 4 during installation. The round hole 11 facilitates the precise installation and positioning of the grinding wheel on the grinding equipment. By cooperating with the positioning components on the equipment, it can ensure that the grinding wheel maintains good concentricity during rotation, reducing vibration and wear caused by eccentricity, and improving the stability and accuracy of the grinding process.

[0030] The working principle of this utility model is as follows: When grinding ceramic anilox rollers, the grinding wheel body 1 is installed on the grinding equipment through the central hole 11. The hole 11 is matched with the positioning component on the equipment to ensure that the grinding wheel body 1 has good concentricity during installation, so that the grinding wheel remains stable during high-speed rotation, reducing vibration and wear caused by eccentricity, and providing a stable foundation for subsequent precision grinding.

[0031] When the equipment is started, the grinding wheel body 1 begins to rotate and contact the ceramic anilox roller for grinding. The triple helical grooves 2 on the surface of the grinding wheel body 1 play a key role. As the grinding wheel rotates, the triple helical grooves 2 continuously rub against the surface of the ceramic anilox roller, grinding away the ceramic material. The groove depth is 0.005-0.01mm, which can accommodate the grinding debris without affecting the strength of the grinding wheel. The grinding debris can be guided and discharged along the helical direction of the triple helical grooves 2, avoiding accumulation on the grinding wheel surface, preventing grinding wheel blockage, and ensuring continuous and efficient grinding. At the same time, the helical inclination angle of the triple helical grooves 2 can be adjusted according to the actual processing requirements. When pursuing higher processing efficiency, the helical inclination angle is increased, which can accelerate the speed of air and grinding fluid entering the grinding contact area and enhance the cooling effect. When the surface flatness of the ceramic anilox roller is required to be high, the helical inclination angle is decreased to ensure the grinding surface quality.

[0032] During the grinding process, the grinding wheel generates a large amount of heat due to friction. At this time, the heat-conducting plates 4 in the front and rear mounting grooves 3 of the grinding wheel body 1 and the heat dissipation holes 9 on the surface work together to dissipate heat. The heat-conducting plates 4 are tightly fitted with the threaded holes 10 and mounting holes 8 on the grinding wheel body 1 through the positioning pins 7 and are firmly installed in the mounting grooves 3, which can quickly conduct the heat from the surface of the grinding wheel away. The heat dissipation holes 9 distributed circumferentially on the surface of the grinding wheel body 1 increase the contact area between the grinding wheel and the air, accelerate the air circulation inside the grinding wheel, and carry away the heat inside the grinding wheel during the air flow. This complements the heat dissipation effect of the heat-conducting plates 4, further reducing the overall temperature of the grinding wheel, reducing the generation of thermal stress cracks, and ensuring the surface quality of the ceramic anilox roller and the service life of the grinding wheel.
