Description

Technical Field

[0001] This utility model relates to the field of grinding disc technology, specifically a grinding disc structure with self-cleaning function. Background Technology

[0002] Grinding discs are mainly used in the semiconductor industry for the production of silicon wafers for ultra-large-scale integrated circuits. They can also be used for grinding and polishing the flat surfaces of sheet or block objects of other materials. Silicon carbide ceramic grinding discs, due to their high hardness, low wear, and thermal expansion coefficient that is basically the same as that of silicon wafers, can meet the requirements of high-speed grinding and polishing, and can effectively ensure the flatness and parallelism of silicon wafers. In the forestry industry, pulping discs are key components in the thermal grinding process of medium-density fiberboard production. In the paper industry, they are the "heart" of the pulping machine, playing a crucial role in the processing of pulp fibers. Each specification of grinding disc has several to dozens of tooth profiles, such as conical grinding discs and disc grinding discs. The design must fully consider factors such as specific surface load and rheological effects to adapt to the requirements of different pulps, paper types, processes, and indicators.

[0003] Existing grinding discs grind workpieces by squeezing and friction. During operation, debris accumulates on the surface of the grinding disc. If not cleaned in time, it will affect the grinding quality of the workpiece. The existing treatment method requires using blades or other objects to scrape off the impurities and clean the grinding disc. However, the grinding disc is relatively wide, making the cleaning of the grinding disc time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to provide a self-cleaning grinding disc structure to solve the problem mentioned in the background art that the existing processing method requires the use of blades or other objects to scrape off impurities and clean the grinding disc, but the grinding disc is wide, which makes cleaning the grinding disc time-consuming and labor-intensive.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning grinding disc structure, including a processing support platform, on which two electric push rods are fixedly connected. The output ends of the electric push rods are fixedly connected to limit pawls. A grinding disc body is mounted on the upper surface of the processing support platform. Positioning pillars are fixedly connected to both ends of the grinding disc body. A support baffle is fixedly connected to the rear surface of the processing support platform. A first motor is fixedly connected to the rear surface of the support baffle. A transmission screw is installed between the support baffle and the processing support platform. An installation slide plate is mounted on the outer surface of the transmission screw. Two cleaning connecting blocks are fixedly connected to the upper outer surface of the installation slide plate. A guide rod is fixedly connected to the surface of the installation slide plate. A cleaning slide plate is mounted on the outer surface of the guide rod. A reciprocating adjustment mechanism is provided above the cleaning slide plate. A second motor drives a transmission gear to rotate, facilitating the transmission gear to mesh with a first and second gear block, respectively, to drive the cleaning slide plate to slide.

[0006] Preferably, the limiting claw is concave and the positioning support is cylindrical, and the positioning support and the limiting claw are engaged.

[0007] By adopting the above technical solution, the concave structure can closely fit the outer surface of the cylindrical positioning support, forming a stable engagement interface, restricting the horizontal displacement of the grinding disc body, ensuring that the grinding disc position is fixed during the grinding process, and avoiding a decrease in grinding accuracy due to shaking.

[0008] Preferably, the support baffle is L-shaped and is rotatably connected to the transmission screw. One end of the shaft of the transmission screw is fixedly connected to the output end of the first motor. The transmission screw is threadedly connected to the mounting plate and is slidably connected to the support baffle.

[0009] Using the above technical solution, the L-shaped structure provides dual support. One end is fixed on the processing support table, and the other end supports the transmission screw, forming a stable mechanical fulcrum and preventing the screw from deviating or shaking when rotating.

[0010] Preferably, the cleaning connecting block has a nozzle on its lower surface, and the nozzle of the cleaning connecting block is designed to be inclined. The mounting plate has a water inlet on its rear surface. One end of the cleaning connecting block is connected to the water inlet of the mounting plate. The guide rod and the cleaning plate are slidably connected.

[0011] Using the above technical solution, the tilted nozzle can spray the cleaning fluid onto the grinding disc surface at a certain angle, enhancing the liquid impact force and effectively flushing away the attached debris; the tilt angle can optimize the cleaning coverage and avoid liquid splashing or cleaning blind spots caused by vertical spraying.

[0012] Preferably, the reciprocating adjustment mechanism includes a second motor, which is fixedly connected to the front surface of the mounting plate. A transmission gear is fixedly connected to the output end of the second motor. A limit frame is fixedly connected to the upper surface of the cleaning plate. A first toothed block is fixedly connected to the upper surface of the cleaning plate, and a second toothed block is fixedly connected to the inner wall of the limit frame.

[0013] Using the above technical solution, the second motor provides the power source and drives the transmission gear to rotate. Through the meshing relationship between the gear and the tooth block, the rotational motion is converted into the linear reciprocating motion of the sweeping slide, thereby realizing the automatic sweeping function and reducing manual intervention.

[0014] Preferably, the transmission gear has a missing tooth design, and the width of the opening of the limiting frame is greater than the width of the transmission gear.

[0015] Using the above technical solution, the missing tooth structure causes the gear to have periodic engagement and disengagement actions when rotating. When the toothed part of the gear engages with the tooth block, it drives the cleaning slide plate to move. When the missing tooth part rotates to the position of the tooth block, the gear disengages from the tooth block, and the cleaning slide plate stops or moves in the opposite direction due to inertia or the limiting structure, thereby realizing the automatic switching of reciprocating motion without the need for a complex reversing mechanism, simplifying the mechanical structure.

[0016] Preferably, the first tooth block and the second tooth block are arranged opposite to each other, and both the first tooth block and the second tooth block are meshed with the transmission gear.

[0017] By adopting the above technical solution, the transmission gear can mesh with the tooth blocks on both sides in sequence when rotating clockwise or counterclockwise. When the gear rotates clockwise, it first meshes with the first tooth block, pushing the cleaning slide plate to the right. When the gear rotates to the part with missing teeth, the cleaning slide plate stops. The gear continues to rotate until it meshes with the second tooth block, pushing the slide plate to the left, thus achieving uninterrupted reciprocating motion.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the self-cleaning grinding disc structure: 1. The concave limiting claw driven by the electric push rod engages with the cylindrical positioning support, which can quickly complete the positioning and fixing of the grinding disc body without the need for additional tools, thus shortening the clamping time. The engaging structure forms a stable mechanical limit, effectively resisting the lateral force during the grinding process and preventing the grinding disc from shaking and affecting the processing accuracy. At the same time, the smooth cylindrical surface design reduces disassembly resistance and improves the efficiency of grinding disc replacement. 2. The first motor drives the transmission screw to move the mounting slide plate laterally, so that the inclined nozzle of the cleaning connecting block can spray cleaning liquid along the width of the grinding disc. The inclined angle optimizes the rinsing effect and covers the entire surface without dead corners. The cleaning slide plate supported by the guide rod is driven by the second motor to drive the transmission gear, which alternately meshes with the first and second tooth blocks to achieve reciprocating sliding, automatically cleaning the debris on the surface of the grinding disc without the need for manual cleaning section by section, solving the problem of time-consuming and labor-intensive traditional cleaning. 3. In the reciprocating adjustment mechanism, the toothed transmission gear and the opposing toothed block cooperate to automatically change the direction of the cleaning slide by the periodic action of the gear's rotational engagement and disengagement. There is no need for complex electrical control or reversing components. The opening width of the limit frame is greater than the width of the gear to ensure full engagement and avoid motion interference, so that the cleaning action is smooth and continuous. Combined with the stability of the screw drive, the entire cleaning system can operate reliably for a long time, improving the automation level and cleaning efficiency of the equipment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a self-cleaning grinding disc structure, including a processing support table 1, electric push rods 2, limiting claws 3, positioning pillars 4, grinding disc body 5, supporting baffle 6, first motor 7, transmission screw 8, mounting plate 9, cleaning connecting block 10, guide rod 11, cleaning plate 12, second motor 13, transmission gear 14, limiting frame 15, first tooth block 16, and second tooth block 17. The processing support table 1 has two electric push rods 2 fixedly connected to its side surface, and the output ends of the electric push rods 2 are fixedly connected to... The limiting claw 3 is located on the upper surface of the processing support table 1, where the grinding disc body 5 is mounted. The limiting claw 3 has a concave design, and the positioning support column 4 has a cylindrical design. The positioning support column 4 and the limiting claw 3 are engaged. When the electric push rod 2 is powered on, it drives the limiting claw 3 to move vertically. Because the limiting claw 3 has a concave design, it can engage with the cylindrical positioning support column 4 at both ends of the grinding disc body 5. After engagement, the limiting claw 3 restricts the lateral displacement of the positioning support column 4, causing the grinding disc body 5 to rise relative to the processing support table 1, ensuring stable position during the cleaning process.

[0023] Both ends of the grinding disc body 5 are fixedly connected to positioning pillars 4. A support baffle 6 is fixedly connected to the rear surface of the processing support table 1. A first motor 7 is fixedly connected to the rear surface of the support baffle 6. The support baffle 6 is L-shaped and is rotatably connected to the transmission screw 8. One end of the shaft of the transmission screw 8 is fixedly connected to the output end of the first motor 7. The transmission screw 8 is threadedly connected to the mounting slide plate 9 and is slidably connected to the support baffle 6. A nozzle is provided on the lower surface of the cleaning connecting block 10, and the nozzle of the cleaning connecting block 10 is designed to be inclined. A water inlet is provided on the rear surface of the mounting slide plate 9. One end of the cleaning connecting block 10 is connected to the water inlet of the mounting plate 9. The guide rod 11 and the cleaning plate 12 are slidably connected. After the first motor 7 starts, it drives the transmission screw 8 to rotate. Since the transmission screw 8 and the mounting plate 9 are threadedly connected, the mounting plate 9 moves laterally along the axis of the transmission screw 8. The cleaning connecting block 10 above the mounting plate 9 moves synchronously with it. The inclined nozzle on the lower surface of the cleaning connecting block 10 sprays cleaning liquid onto the surface of the grinding disc body 5. The inclined angle design can enhance the flushing force and expand the coverage area. The cleaning liquid is introduced through the water inlet on the rear surface of the mounting plate 9 and delivered to the nozzle.

[0024] A transmission screw 8 is installed between the support baffle 6 and the processing support table 1. A mounting plate 9 is mounted on the outer surface of the transmission screw 8. Two cleaning connecting blocks 10 are fixedly connected to the upper outer surface of the mounting plate 9. A guide rod 11 is fixedly connected to the surface of the mounting plate 9. A cleaning plate 12 is mounted on the outer surface of the guide rod 11. The reciprocating adjustment mechanism includes a second motor 13, which is fixedly connected to the front surface of the mounting plate 9. A transmission gear 14 is fixedly connected to the output end of the second motor 13. A limit frame 15 is fixedly connected to the upper surface of the cleaning plate 12. A first toothed block 16 is fixedly connected to the upper surface of the cleaning plate 12. The inner wall of the 15 is fixedly connected to the second tooth block 17. The second motor 13 drives the transmission gear 14 to rotate. The transmission gear 14 is designed with missing teeth. It first meshes with the first tooth block 16 on the upper surface of the cleaning slide plate 12, pushing the cleaning slide plate 12 to slide along the guide rod 11. When the transmission gear 14 rotates to the point where the missing tooth part disengages from the first tooth block 16, the cleaning slide plate 12 stops. Then the transmission gear 14 continues to rotate and meshes with the second tooth block 17 on the inner wall of the limiting frame 15, pushing the cleaning slide plate 12 to slide in the opposite direction, realizing reciprocating motion. The cleaning slide plate 12 removes debris from the surface of the grinding disc body 5 through friction or scraping action, and achieves double cleaning with the cleaning fluid.

[0025] A reciprocating adjustment mechanism is provided above the cleaning slide plate 12. The mechanism drives the transmission gear 14 to rotate via the second motor 13, which facilitates the engagement of the transmission gear 14 with the first tooth block 16 and the second tooth block 17 to drive the cleaning slide plate 12 to slide. The transmission gear 14 has a missing tooth design. The width of the opening of the limiting frame 15 is greater than the width of the transmission gear 14. The first tooth block 16 and the second tooth block 17 are arranged opposite each other, and both the first tooth block 16 and the second tooth block 17 are engaged with the transmission gear 14. After the grinding work is completed, the first motor 7 is started first to move the mounting slide plate 9 and the cleaning connecting block 10 laterally. At the same time, the cleaning fluid supply is turned on to perform a preliminary rinse on the surface of the grinding disc. Then, the second motor 13 is started, and the cleaning slide plate 12 is driven to reciprocate through the engagement of the transmission gear 14 and the tooth block to remove stubborn debris. The electric push rod 2 can release the limiting claw 3 after cleaning, which facilitates the disassembly of the grinding disc body 5 for subsequent maintenance or replacement.

[0026] Working principle: When using the self-cleaning grinding disc structure, the electric push rod 2 drives the concave limiting claw 3 to engage with the cylindrical positioning pillars 4 at both ends of the grinding disc body 5 to fix the grinding disc. The first motor 7 drives the transmission screw 8 to rotate, causing the mounting slide plate 9 to move laterally. The inclined nozzle of the cleaning connecting block 10 on it sprays cleaning liquid to rinse the surface of the grinding disc. The second motor 13 drives the toothed transmission gear 14 to alternately mesh with the first tooth block 16 on the cleaning slide plate 12 and the second tooth block 17 on the inner wall of the limiting frame 15, so that the cleaning slide plate 12 slides back and forth along the guide rod 11 to remove debris and increase the overall practicality.

[0027] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
