Description

Technical Field

[0001] This application relates to the field of grinding wheel production and processing, and in particular to an abrasive leveling mechanism and grinding wheel production equipment. Background Technology

[0002] A grinding wheel is a common grinding device, typically containing an embedded mesh fabric. This mesh fabric enhances the structural strength of the grinding wheel and prevents breakage during high-speed operation. The grinding wheel body mainly consists of abrasive particles and mesh fabric. The abrasive particles usually contain materials such as white corundum, phenolic resin, and cryolite; the mesh fabric is generally made of fiberglass. During the manufacturing process, the abrasive particles and mesh fabric are alternately laid in a mold, and then pressure is applied to press the multi-layered structure into a single unit. After thermosetting, the grinding wheel is obtained.

[0003] After the abrasive is filled into the mold, it needs to be leveled because the abrasive accumulates in some areas. The conventional leveling method is to use a horizontal scraper that rotates relative to the mold to level the abrasive. That is, the scraper gradually descends to push the abrasive that is higher than the preset height to the empty space.

[0004] However, this leveling method is not only inefficient, but also has limited leveling effect. The abrasive may take a long time to move to the gap when pushed by the scraper, or it may not even flow to the gap at all. For example, when the abrasive pile is in the middle, the abrasive is far from the inner edge of the mold. It is difficult to move the excessively high abrasive to the inner edge of the mold by the pusher alone, or it may take a lot of time.

[0005] To address the aforementioned issues, some manufacturers choose to place materials in different areas within the mold to form multiple material piles, and then reduce the initial height of the scraper for leveling. Placing materials in different areas within the mold allows the abrasive to be more dispersed initially, facilitating subsequent leveling; while reducing the initial height of the scraper allows it to move more of the extra-tall abrasive material initially. For example, by setting the initial height of the scraper's bottom to equal a preset height, the scraper can move all the extra-tall abrasive material from the start, thus achieving rapid leveling.

[0006] However, adding multiple piles of abrasive increases the complexity of the feeding process, and pushing too much abrasive at once with the scraper may disturb the mesh fabric beneath it. Furthermore, while the above methods improve the leveling speed, they cannot completely guarantee that excessively high abrasive levels will quickly fill the corners. Secondly, traditional leveling methods only remove the abrasive from the upper layer of the pile, while the abrasive in the lower layer may exhibit gaps in some areas due to bridging, compromising the uniformity of the abrasive and affecting the quality of the grinding wheel. Summary of the Invention

[0007] To address the issues of poor abrasive leveling efficiency and effect, this application provides an abrasive leveling mechanism and grinding wheel production equipment.

[0008] In a first aspect, this application provides an abrasive leveling mechanism, comprising: A mold used to hold alternating layers of abrasive and mesh fabric; A leveling assembly includes a leveling execution unit and a leveling drive unit; the leveling execution unit includes a scraper, a conveying roller, and a conveying drive module; the bottom surface of the scraper is horizontally arranged and the scraper is connected to the leveling drive unit, the leveling drive unit is used to drive the scraper to rotate; the conveying roller is horizontally rotatably mounted on the scraper; the conveying drive module is connected to the conveying roller and is used to drive the conveying roller to rotate.

[0009] By adopting the above technical solution, the mold can accommodate alternating layers of abrasive and mesh cloth. The scraping drive unit drives the scraper to rotate, which can scrape the abrasive in the mold to make the abrasive distribution more uniform. The conveying drive module drives the conveying roller to rotate, thereby realizing the horizontal conveying of abrasive. Working together with the scraper, it helps to convey and level the abrasive horizontally. In addition, the conveying roller can generate a certain stirring effect on the abrasive when conveying it, thereby avoiding bridging and ensuring the uniformity of abrasive distribution.

[0010] Optionally, the conveying roller is located in front of the rotation path of the scraper, and the bottom height of the conveying roller is higher than or equal to the bottom height of the scraper.

[0011] By adopting the above technical solution, the conveying roller is located in front of the scraper rotation path and its bottom height is higher than or equal to the bottom height of the scraper. This allows the conveying roller to contact the abrasive before the scraper, realizing the horizontal conveying of the abrasive and reducing the height of the material pile. The scraper can then follow closely behind to flatten the horizontally distributed abrasive. At this time, the height of the material pile has already decreased, which can reduce the probability of the mesh cloth below being disturbed during the scraper flattening process. In addition, for some corner abrasive, the scraper can make it accumulate in front of the scraper, ensuring that this abrasive can be smoothly conveyed by the conveying roller.

[0012] Optionally, the bottom height of the conveying roller is lower than the bottom height of the scraper; the conveying roller is also used to stir the abrasive.

[0013] By adopting the above technical solution, the conveying roller can achieve horizontal conveying, stirring and leveling of abrasive by its own rotation in conjunction with the circumferential rotation of the scraper, ensuring the uniformity and rapid leveling of the abrasive; the bottom height of the conveying roller is lower than the bottom height of the scraper, which can prevent the abrasive from being pushed away by the scraper before interacting with the conveying roller.

[0014] Optionally, the conveying roller has a forward rotation state and a reverse rotation state.

[0015] By adopting the above technical solution, the abrasive leveling mechanism can utilize the forward and reverse rotation of the conveying rollers to adjust the conveying direction and leveling effect of the abrasive according to actual needs, thereby increasing the flexibility of the abrasive leveling operation.

[0016] Optionally, the abrasive leveling mechanism further includes a mesh pressing assembly, which includes a mesh pressing execution unit and a mesh pressing drive unit; the mesh pressing execution unit is used to press down the mesh cloth inside the mold; the mesh pressing drive unit is connected to the mesh pressing execution unit.

[0017] By adopting the above technical solution and adding a mesh pressing component, the mesh pressing execution unit can press down the mesh cloth in the mold to avoid disturbing the mesh cloth when the abrasive is added or the abrasive is initially leveled; the mesh pressing drive unit provides power for the operation of the mesh pressing execution unit, so that the mesh pressing execution unit presses down on the mesh cloth or moves away from the mesh cloth, ensuring that the mesh cloth is laid flat, which helps to improve the quality of the alternating layering of abrasive and mesh cloth.

[0018] Optionally, the pressing unit includes an inner pressing ring, an outer pressing ring, and a connecting rod; the inner pressing ring and the outer pressing ring are coaxially arranged and connected by the connecting rod; the connecting rod is connected to the pressing drive unit.

[0019] By adopting the above technical solution, the abrasive leveling mechanism can use the mesh pressing assembly to press down the mesh cloth in the mold. The inner and outer pressure rings of the mesh pressing execution unit are coaxially set and connected by a connecting rod, which can stably apply pressure to the mesh cloth, ensure the flatness of the mesh cloth, and make the mesh cloth and abrasive better match, which is beneficial to the subsequent production and forming of grinding wheels.

[0020] Optionally, the top surface of the inner pressure ring has a conical structure with a higher inner surface and a lower outer surface; the top surface of the outer pressure ring has a conical structure with a lower inner surface and a higher outer surface.

[0021] By adopting the above technical solution, the top surface of the inner pressure ring has a conical structure with a high inner surface and a low outer surface, and the top surface of the outer pressure ring has a conical structure with a low inner surface and a high outer surface. This allows the abrasive material falling on the top of the inner and outer pressure rings to slide down naturally, avoiding abrasive material retention that could lead to abrasive material loss in subsequent grinding wheels.

[0022] Optionally, the pressing wire drive unit is used to drive the pressing wire execution unit to move up and down to the top or bottom of the leveling execution unit; Both the inner pressure ring and the outer pressure ring are provided with notches for the leveling execution unit to pass through; The scraper is also used to push the abrasive on the inner pressure ring and the outer pressure ring toward the notch.

[0023] By adopting the above technical solution, the pressing drive unit drives the pressing execution unit to rise and fall above or below the leveling execution unit, and the inner and outer pressing rings are provided with notches for the leveling execution unit to pass through, so that the pressing and leveling operations do not interfere with each other, improving operational flexibility and efficiency; the scraper can be used to push the abrasive on the inner and outer pressing rings toward the notches, which can reduce the residue of abrasive on the pressing execution unit, ensuring the abrasive laying effect and the cleanliness of the mechanism.

[0024] Secondly, this application also provides a grinding wheel production equipment, including: a conveyor line, an abrasive feeding assembly, a mesh cloth placement assembly, an extrusion molding assembly, and the aforementioned abrasive leveling mechanism; The conveyor line is used to transport molds.

[0025] By adopting the above technical solution, the conveyor line can transport the mold, allowing the mold to pass through multiple stations such as the abrasive feeding component, the abrasive leveling mechanism, the mesh cloth placement component, and the extrusion molding component, to complete the alternating layering, leveling, and extrusion molding processes of abrasive and mesh cloth. The mold of the abrasive leveling mechanism can accommodate abrasive and mesh cloth, the leveling component can level the abrasive, the conveying roller can convey or stir the abrasive and can also rotate in both directions, and the mesh pressing component can press down on the mesh cloth. All components work together to ensure the smooth progress of the grinding wheel production process and the product quality.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. This application is equipped with a scraper and a conveying roller. The rotation of the scraper can scrape the abrasive in the mold to make the abrasive distribution more uniform. The conveying drive module drives the conveying roller to rotate, which can realize the horizontal conveying of the abrasive. Working together with the scraper, it helps to convey and flatten the abrasive horizontally. The conveying roller can produce a certain stirring effect on the abrasive when conveying it, thereby avoiding bridging and ensuring the uniformity of abrasive distribution. 2. When the conveying roller is located in front of the scraper's rotation path and its bottom height is higher than or equal to the scraper's bottom height, the conveying roller can contact the abrasive before the scraper, achieving horizontal conveying of the abrasive. The scraper can then follow closely behind to level the horizontally distributed abrasive. During the leveling process, the mesh cloth below is not easily disturbed. In addition, for some corner abrasive, the scraper can cause it to accumulate in front of the scraper, ensuring that this abrasive can be smoothly conveyed by the conveying roller. When the bottom height of the conveying roller is lower than the bottom height of the scraper, the conveying roller can be lowered even further to obtain better abrasive conveying and mixing effects, thereby improving the quality of the grinding wheel. 3. This application is equipped with a mesh pressing component. The mesh pressing execution unit of the mesh pressing component can press down the mesh cloth in the mold to avoid disturbing the mesh cloth when the abrasive is added or during the initial stage of abrasive leveling. The mesh pressing component and the leveling component work together to effectively improve the leveling quality. Attached Figure Description

Detailed Implementation

[0029] The following is in conjunction with the appendix Figures 1 to 5 This application will be described in further detail.

[0030] Example 1

[0031] like Figures 1 to 3 As shown in the figure, this application discloses an abrasive leveling mechanism, including a mold 1, a scraping component 2, and a pressing component 3.

[0032] Specifically, mold 1 has a cylindrical receiving cavity with an opening at the top, and the interior of the cavity is used to accommodate alternately layered abrasive and mesh fabric. Taking a grinding wheel with a single-layer mesh fabric structure as an example, a layer of mesh fabric is sandwiched between two layers of abrasive. During grinding wheel preparation, the first layer of abrasive, the mesh fabric, and the second layer of abrasive need to be laid sequentially. After laying, the multi-layer structure is pressed together as a whole, and the grinding wheel is obtained after processes such as heating and curing. The abrasive is usually added to mold 1 in powder form, and the abrasive needs to be spread evenly before the mesh fabric can be placed on top of the abrasive layer.

[0033] The leveling assembly 2 includes a first mounting bracket 21, a lifting drive component 22, a leveling drive unit 23, and a leveling execution unit 24. The leveling drive unit 23 includes a second mounting bracket 231, a third mounting bracket 232, a first motor 233, and a rotating shaft 234. The lifting drive component 22 is mounted on the first mounting bracket 21 and connected to the second mounting bracket 231. The lifting drive component 22 is used to drive the second mounting bracket 231 to rise and fall. The lifting drive component 22 can be a vertically arranged cylinder.

[0034] The first motor 233 is mounted on the second mounting bracket 231, and the third mounting bracket 232 is located below the second mounting bracket 231. The first motor 233 is connected to the third mounting bracket 232 via a vertically arranged rotating shaft 234. The first motor 233 is used to drive the third mounting bracket 232 to rotate.

[0035] The leveling execution unit 24 is mounted on the third mounting frame 232. When the third mounting frame 232 rotates, the leveling execution unit 24 can level the abrasive inside the mold 1. The leveling execution unit 24 includes a scraper 241, a conveying roller 242, and a conveying drive module 243. The scraper 241 is rectangular, vertically arranged, and connected to the third mounting frame 232. When the scraper 241 rotates with the third mounting frame 232, it can level the abrasive. The bottom of the scraper 241 remains horizontal to better level the abrasive.

[0036] like Figures 2 to 4 As shown, the conveying roller 242 is horizontally rotatable on the scraper 241, and the bottom height of the conveying roller 242 is equal to or slightly higher than the bottom height of the scraper 241. The conveying drive module 243 is connected to the conveying roller 242 and is used to drive the conveying roller 242 to rotate. The conveying roller 242 can realize the horizontal conveying of abrasive by rotating, which helps to quickly distribute the abrasive in the material pile to various areas, and helps to improve the leveling efficiency and effect. In addition, the conveying roller 242 can also play a stirring role in the horizontal conveying of materials, which helps to reduce bridging and improve the uniformity of abrasive. The conveying drive module 243 includes a second motor 2431, a protective box 2432, and two bevel gears 2433. One bevel gear 2433 is sleeved on the conveying roller 242, and the other bevel gear 2433 is connected to the second motor 2431 for transmission. The rotation of the conveying roller 242 can be realized by the second motor 2431 driving the bevel gear 2433 to rotate. The protective box 2432 is mounted on the scraper 241 or the third mounting bracket 232. The second motor 2431 and the two bevel gears 2433 are both located inside the protective box 2432 to prevent abrasive materials from affecting the meshing of the two bevel gears 2433. The protective box 2432 is provided with a through hole for the conveyor roller 242 to pass through.

[0037] Furthermore, the second motor 2431 can drive the conveying roller 242 to rotate forward and reverse, thereby changing the conveying direction of the conveying roller 242 for the abrasive.

[0038] Furthermore, the conveying roller 242 is located in front of the rotation path of the scraper 241, so that when the third mounting bracket 232 rotates, the conveying roller 242 can contact the abrasive first, thereby causing the abrasive to disperse quickly; the scraper 241 then contacts the abrasive, thereby flattening the dispersed abrasive. In addition, for abrasive located at corners (e.g., around the side walls of the receiving cavity), the conveying efficiency of the conveying roller 242 is relatively low, while the scraper 241 can push the abrasive that is too high at the corners to move. This part of the abrasive accumulates in front of the moving path of the scraper 241, making it easier to be conveyed away by the conveying roller 242.

[0039] like Figures 2 to 4 As shown, the mesh pressing assembly 3 includes a mesh pressing execution unit 31 and a mesh pressing drive unit 32. The mesh pressing execution unit 31 includes an inner pressure ring 311, an outer pressure ring 312, and a connecting rod 313. The inner pressure ring 311 and the outer pressure ring 312 are coaxially arranged and connected by the connecting rod 313. The mesh pressing drive unit 32 can also be a vertically arranged cylinder. The mesh pressing drive unit 32 is connected to the second mounting bracket 231 and the connecting rod 313 respectively. The mesh pressing drive unit 32 is used to drive the mesh pressing execution unit 31 to rise and fall, thereby pressing down the mesh cloth in the receiving cavity through the inner pressure ring 311 and the outer pressure ring 312 to prevent wrinkles from appearing in the mesh cloth when abrasive is put into the receiving cavity.

[0040] Before abrasive is applied to the mesh fabric, the mesh pressing unit 31 is positioned below the leveling unit 24 to press the mesh fabric firmly. When leveling the applied abrasive, the mesh pressing unit 31 rises above the leveling unit 24 under the drive of the mesh pressing drive unit 32, allowing the leveling unit 24 to perform subsequent leveling operations. Both the inner pressure ring 311 and the outer pressure ring 312 have notches 314 for the leveling unit 24 and the third mounting bracket 232 to pass through. These notches 314 prevent interference between the mesh pressing unit 31 and the leveling unit 24 and the third mounting bracket 232 during lifting and lowering.

[0041] In this embodiment, the process of placing abrasive on the mesh cloth placed in the receiving cavity and scraping the abrasive is as follows: the mesh pressing drive unit 32 drives the mesh pressing execution unit 31 to descend, so that the mesh pressing execution unit 31 enters the receiving cavity and presses the mesh cloth tightly; then, abrasive is placed into the receiving cavity; then, the first motor 233 drives the third mounting bracket 232 to rotate forward and backward within a certain angle range, so that the scraper 241 can initially scrape the abrasive without interfering with the mesh pressing assembly 3, helping the concentrated abrasive to initially disperse to the surroundings. After initial scraping, the mesh pressing drive unit 32 drives the mesh pressing execution unit 31 to rise, so that the tops of the inner pressure ring 311 and the outer pressure ring 312 abut against the bottom of the scraper 241. The first motor 233 drives the scraper 241 rotates within a certain angle range to push the abrasive material stuck on the top of the inner pressure ring 311 and the outer pressure ring 312 toward the notch 314 and let the abrasive material fall naturally; then, the scraping execution unit 24 returns to directly above the notch 314, and then the pressing mesh drive unit 32 drives the pressing mesh execution unit 31 to rise above the third mounting frame 232 and the scraping execution unit 24; then, the lifting drive 22 drives the scraping execution unit 24 to descend further, so that the bottom height of the scraper 241 is flush with the preset height of the abrasive layer; then the first motor 233 drives the scraper 241 to rotate, and the second motor 2431 drives the conveying roller 242 to rotate. The conveying roller 242 and the scraper 241 cooperate with each other to complete the horizontal conveying and scraping of the abrasive material.

[0042] like Figure 5 As shown, this embodiment also provides a grinding wheel production equipment, including a conveyor line 100, an abrasive feeding assembly 200, a mesh cloth placement assembly 300, an extrusion molding assembly 400, and an abrasive leveling mechanism.

[0043] The conveyor line 100 is used to transport the mold 1. The specific transport method is not strictly limited. For example, the mold 1 can be pushed to slide on the conveyor line 100 by setting the conveyor cylinder 101 so that the mold 1 can be transferred between various workstations.

[0044] The abrasive feeding assembly 200, the mesh cloth placement assembly 300, the extrusion molding assembly 400, and the abrasive leveling mechanism are all located around the conveyor line 100. The number of abrasive feeding assemblies 200, mesh cloth placement assemblies 300, and abrasive leveling mechanisms depends on the type of grinding wheel being produced. Taking a single mesh cloth structure grinding wheel as an example, it includes two abrasive layers and a mesh cloth between the two abrasive layers. Therefore, the corresponding grinding wheel production equipment includes one mesh cloth placement assembly 300, two abrasive feeding assemblies 200, and two abrasive leveling mechanisms. The specific arrangement order of the abrasive feeding assembly 200, abrasive leveling mechanism, mesh cloth placement assembly 300, and extrusion molding assembly 400 along the conveyor line 100 is prior art, and the specific structure of the abrasive feeding assembly 200, mesh cloth placement assembly 300, and extrusion molding assembly 400 is also prior art and will not be described in detail.

[0045] Example 2

[0046] The difference between this embodiment and Embodiment 1 is that: The bottom height of the conveying roller 242 is lower than the bottom height of the scraper 241. When the abrasive is leveled, the conveying roller 242 can be lowered so that the bottom height of the conveying roller 242 is lower than the preset height. The abrasive piled up in a concentrated manner is quickly dispersed by the rotation of the conveying roller 242 itself. Then, the conveying roller 242 is raised so that the bottom height of the conveying roller 242 is equal to the preset height. The abrasive is leveled by the rotation of the conveying roller 242 following the third mounting frame 232. The horizontal conveying, stirring and leveling of the abrasive are completed by the conveying roller 242.

[0047] In this embodiment, the scraper 241 is only used to fix the conveyor roller 242. By controlling the bottom height of the conveyor roller 242 to be lower than the bottom height of the scraper 241, when the bottom height of the conveyor roller 242 is lower than the preset height, the bottom height of the scraper 241 is still higher than or equal to the preset height, thus preventing the scraper 241 from scraping away the abrasive material that is lower than the preset height.

[0048] Of course, to improve the leveling effect and efficiency, an additional scraping plate (not shown in the figure) can be added to level the dispersed abrasive. The scraping plate can be moved by adding a robotic arm (not shown in the figure) or other moving devices, so that the scraping plate can play a leveling role.

[0049] like Figure 4 As shown, the top surface of the inner pressure ring 311 has a conical structure with a higher inner surface and a lower outer surface, and the top surface of the outer pressure ring 312 has a conical structure with a lower inner surface and a higher outer surface, so that the abrasive at the top of the inner pressure ring 311 and the outer pressure ring 312 can slide off naturally without the need for scraping by the scraper 241 or manual scraping.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
