Description

Technical Field

[0001] This invention relates to the field of abrasive processing technology, specifically to a grinding wheel abrasive particle size classification and batching equipment. Background Technology

[0002] As an important tool widely used in machining, the quality and performance of grinding wheels directly affect the machining accuracy, surface quality and production efficiency of workpieces. The particle size distribution of abrasive is one of the core factors that determine the grinding performance of grinding wheels. The uniformity, purity and proportion of abrasive particle size directly affect the grinding efficiency, durability and surface quality of grinding wheels.

[0003] Currently, existing abrasive wheel classification equipment has the following main shortcomings in practical applications. First, the cleaning process during magnetic separation for iron removal is incomplete. Abrasive raw materials inevitably contain ferromagnetic impurities, which can cause scratches and other defects on the workpiece surface during grinding wheel manufacturing and use. Existing equipment generally uses magnetic separation rollers to remove iron from the abrasive, but the cleaning process after the magnetic separation rollers adsorb impurities has significant flaws. Most equipment only has a simple scraper on one side of the magnetic separation roller for scraping, and even after scraping, fine iron filings or dust remain on the surface of the magnetic separation roller. If the cleaning is not thorough... If the magnetic separation roller is covered by an excessively thick layer of ferromagnetic impurities, whether in a timely or incomplete manner, the impurities will be far from the effective range of the magnetic field, resulting in a significant decrease in magnetic force and a sharp decline in subsequent magnetic separation efficiency. In addition, the problem of screen hole clogging has been a long-standing issue. Although existing technologies include placing bouncing balls inside the screen frame and using vibration to drive the bouncing balls to impact the screen plate, traditional bouncing balls are often loosely placed, with random and uncontrollable trajectories and dispersed impact force. As the material layer thickens, the cleaning effect is greatly reduced. Therefore, it is necessary to avoid the above situations in order to improve the efficiency and quality of abrasive grading and batching. Summary of the Invention

[0004] The purpose of this invention is to provide a grinding wheel abrasive particle size classification and batching equipment.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A grinding wheel abrasive particle size classification and batching device includes a frame and further includes:

[0007] A grading bin, mounted on the frame, is used to classify the abrasive particles by size.

[0008] A feeding unit is located at the inlet end of the grading bin and is used to supply abrasive to the grading bin.

[0009] The grading chamber is equipped with a grading sieve plate and a clamping plate; the grading chamber is also equipped with a discharge hopper corresponding to different particle size areas of the grading sieve plate.

[0010] The feeding unit includes a feeding bin, a feeding hopper, a magnetic separator roller, and a cleaning mechanism; the feeding hopper is located above the feeding bin;

[0011] The magnetic separator is rotatably disposed inside the feed bin and is used to adsorb ferromagnetic impurities in the abrasive.

[0012] The cleaning mechanism is used to clean the impurities adsorbed on the surface of the magnetic separator roller.

[0013] Furthermore, the cleaning mechanism includes an irregularly shaped cleaning plate; the irregularly shaped cleaning plate is fixedly connected inside the feeding hopper; the irregularly shaped cleaning plate includes a plate body, a scraper integrally disposed on one side of the plate body, a receiving plate on the other side of the scraper, and a cleaning brush disposed inside the plate body; the scraper surface is provided with a discharge hole.

[0014] Furthermore, both the scraper and the cleaning brush are in contact with the surface of the magnetic separator roller; the scraper is located below the magnetic separator roller; the receiving plate is located above the magnetic separator roller; the end of the receiving plate near the magnetic separator roller has an arc-shaped structure; the arc-shaped structure is used to receive the abrasive falling into the feed bin; the feed bin is located below the magnetic separator roller and has a cleaning bin and a collection box; a movable screw is rotatably installed inside the cleaning bin; the collection box is located below the cleaning bin; a movable block is threaded onto the movable screw; a cleaning push plate is fixedly connected to the movable block; the cleaning push plate is located inside the collection box.

[0015] Furthermore, an anti-clogging component is provided inside the grading chamber; the anti-clogging component is located between the grading screen plate and the clamping plate, and is used to apply vibration to the grading screen plate; the anti-clogging component includes a connecting column and a jumping plate; the connecting column is fixedly installed inside the grading chamber; one end of the jumping plate is rotatably installed on the connecting column; a jumping ball is integrally connected to the jumping plate.

[0016] Furthermore, a side plate is fixedly connected to the side wall of the feeding hopper; a telescopic spring is fixedly connected to the side plate; an anti-blocking plate is fixedly connected to the end of the telescopic spring away from the side plate; the anti-blocking plate and the receiving plate are located below the feeding hopper.

[0017] Furthermore, the side wall of the feed hopper is rotatably equipped with pulleys; there are two sets of pulleys, and the two sets of pulleys are respectively connected to the shaft ends of the magnetic separator and the moving lead screw; a connecting belt is sleeved on the pulley.

[0018] Furthermore, discharge chutes are provided on both sides of the feeding hopper; the discharge chutes are connected to the discharge ends on both sides of the collection box.

[0019] Furthermore, the grading sieve plates are inclined from top to bottom, and the aperture of the multiple grading sieve plates decreases sequentially from top to bottom.

[0020] Furthermore, a flexible connecting pipe is fixedly connected to the bottom of the feeding hopper; the end of the flexible connecting pipe away from the feeding hopper is fixedly connected to the grading hopper.

[0021] Furthermore, the frame is equipped with a motor assembly for driving the overall vibration of the grading bin.

[0022] The beneficial effects of this invention are:

[0023] (1) By sequentially setting the scraper and cleaning brush along the rotation direction of the magnetic separator roller, the scraper first scrapes off the large metal impurities adsorbed on the surface of the magnetic separator roller, and the cleaning brush then performs fine cleaning on the roller surface, thus realizing two-stage gradient cleaning of the magnetic separator roller. Compared with the single scraping method in the prior art, the present invention effectively avoids the problem of residual fine iron filings and dust on the surface of the magnetic separator roller, ensuring that the magnetic separator roller always maintains the best magnetic adsorption capacity during continuous operation, and significantly improving the stability and continuity of the abrasive iron removal effect.

[0024] (2) The present invention sets a receiving plate on the irregular cleaning plate and designs the end of the receiving plate near the magnetic separator roller as an arc structure, so that the abrasive falls into the feed bin and is first received and buffered at the arc structure. The arc structure effectively avoids the problem that the abrasive slides down the surface of the magnetic separator roller quickly without being fully magnetically separated, prolongs the contact time between the abrasive and the magnetic separator roller, and ensures that the ferromagnetic impurities are fully adsorbed before entering the next process, which greatly improves the capture efficiency of the magnetic separator roller for impurities in the abrasive.

[0025] (3) The present invention provides an anti-blocking plate connected by a telescopic spring on the side wall of the feed hopper. When the falling abrasive impacts the anti-blocking plate, it can move back and forth through the elastic deformation of the telescopic spring, thereby creating periodic disturbance and guidance for the material. This structure can automatically adjust the guidance force according to the material flow rate. When the material flow rate is large, the impact force is large, the displacement amplitude of the anti-blocking plate is large, and the guidance effect is enhanced. When the material flow rate is small, it automatically resets, realizing adaptive anti-blocking of the feed channel and effectively avoiding the accumulation and bridging of abrasive between the receiving plate and the anti-blocking plate.

[0026] (4) The present invention provides an integrated anti-clogging component consisting of a connecting column, a jumping plate and a jumping ball under the grading screen plate. One end of the jumping plate is rotatably mounted on the connecting column and the jumping ball is integrally connected to the end of the jumping plate. When the grading bin vibrates, the jumping plate generates a stable reciprocating swing relative to the connecting column, which drives the jumping ball to make a concentrated and continuous impact on the bottom of the grading screen plate. Compared with the traditional loosely placed jumping ball, the integrated structure of the present invention makes the movement trajectory of the jumping ball more stable and controllable and the impact force more concentrated. It effectively solves the problem that the cleaning effect of the traditional jumping ball becomes worse and the screen holes become more and more clogged when the material layer becomes thicker, which greatly improves the reliability and durability of anti-clogging.

[0039] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1-10 As shown, this application provides a grinding wheel abrasive particle size classification and batching equipment, including a frame 3, and further including:

[0041] The grading chamber 1 is set on the frame 3 and is used to classify the abrasive by particle size.

[0042] Feeding unit 2 is located at the inlet end of the grading chamber 1 and is used to supply abrasive to the grading chamber 1;

[0043] The grading chamber 1 is provided with a grading sieve plate 11 and a clamping plate 12; the grading chamber 1 is also provided with a discharge chamber 13 corresponding to different particle size areas of the grading sieve plate 11.

[0044] The feeding unit 2 includes a feeding bin 21, a feeding hopper 211, a magnetic separator 22, and a cleaning mechanism; the feeding hopper 211 is disposed above the feeding bin 21.

[0045] The magnetic separator 22 is rotatably disposed in the feed bin 21 and is used to adsorb ferromagnetic impurities in the abrasive.

[0046] The cleaning mechanism is used to clean impurities adsorbed on the surface of the magnetic separator 22;

[0047] The cleaning mechanism includes an irregularly shaped cleaning plate 25; the irregularly shaped cleaning plate 25 is fixedly connected inside the feeding hopper 21; the irregularly shaped cleaning plate 25 includes a plate body, a scraper 253 integrally disposed on one side of the plate body, a receiving plate 251 on the other side of the scraper 253, and a cleaning brush 252 disposed inside the plate body; the scraper 253 has a discharge hole 254 on its surface.

[0048] Both the scraper 253 and the cleaning brush 252 are in contact with the surface of the magnetic separator 22; the scraper 253 is located below the magnetic separator 22; the receiving plate 251 is located above the magnetic separator 22; the end of the receiving plate 251 near the magnetic separator 22 is an arc-shaped structure; the arc-shaped structure is used to receive the abrasive falling into the feed bin 21; the feed bin 21 is located below the magnetic separator 22 and has a cleaning bin 26 and a collection box 23; a movable screw 261 is rotatably installed inside the cleaning bin 26; the collection box 23 is located below the cleaning bin 26; a movable block 262 is threadedly connected to the movable screw 261; a cleaning push plate 263 is fixedly connected to the movable block 262; the cleaning push plate 263 is located inside the collection box 23.

[0049] During operation, the grading bin 1 stands on the frame 3, and the feeding bin 21 in the feeding unit 2 is positioned above the grading bin 1. During batching, abrasive material is poured from the feeding hopper 211 into the feeding bin 21. After entering the feeding bin 21, the abrasive material comes into contact with the magnetic separation roller 22 inside the feeding bin 21. Simultaneously, an external motor drives the magnetic separation roller 22 to rotate counterclockwise. After falling from the feeding hopper 211 into the feeding bin 21, the abrasive material first passes through the magnetic separation roller 22. Ferromagnetic impurities in the abrasive material are adsorbed onto the surface of the magnetic separation roller 22. As the magnetic separation roller 22 rotates counterclockwise, the roller surface adsorbed with impurities rotates to... The irregular cleaning plate 25 is positioned such that the scraper 253 is upstream of the cleaning brush 252. That is, the roller surface with adsorbed impurities will first pass through the scraper 253. The scraper 253 forcibly scrapes away large or tightly attached metal impurities from the surface of the magnetic separator 22. The scraped-off impurities will fall into the collection box 23 below for centralized collection and processing. Subsequently, the magnetic separator 22 will continue to rotate to the cleaning brush 252. The cleaning brush 252 cleans the roller surface that still has fine iron filings or dust after scraping, ensuring that the surface of the magnetic separator 22 remains clean to restore the best magnetic adsorption capacity.

[0050] Most importantly, the receiving plate 251 on the irregular cleaning plate 25 is close to the magnetic separator roller 22, and the end of the receiving plate 25 is an arc-shaped structure, forming an appropriate receiving gap between the two. After the abrasive falls into the feed bin 21 through the feed hopper 211, it first falls on the arc-shaped structure of the receiving plate 251. This arc-shaped structure plays a role in receiving and buffering the falling abrasive, preventing the abrasive from sliding down the surface of the magnetic separator roller 22 quickly without sufficient magnetic separation. Under the guidance of the arc-shaped structure, the abrasive will first stay near the surface of the magnetic separator roller 22, prolonging the contact time between the abrasive and the magnetic separator roller 22, ensuring that the ferromagnetic impurities in the abrasive are fully adsorbed by the magnetic separator roller 22. Subsequently, as the magnetic separator roller 22 rotates, the abrasive is conveyed downward along the surface of the magnetic separator roller 22 under the guidance of the arc-shaped structure and enters the subsequent process. Through the arc-shaped receiving structure on the receiving plate 251, the adsorption efficiency of the magnetic separator roller 22 for impurities in the abrasive is improved, avoiding the problem of insufficient magnetic separation caused by the abrasive falling too fast.

[0051] It should be noted that the impurities cleaned by the cleaning brush will fall to the discharge hole 254 by gravity, and then fall into the collection box 23 below through the discharge hole 254, where they will collect with the impurities scraped off by the scraper 253. This prevents impurities from accumulating in the cavity where the cleaning brush 252 is located. Once the impurities reach the discharge hole 254, they will leave the effective range of the magnetic field of the magnetic separator 22, preventing the impurities from being attracted by the magnetic separator 22 again. Even if they are attracted, they will be cleaned again by the cleaning brush 252 to ensure that the roller surface is clean and does not affect the removal of impurities from the abrasive.

[0052] like Figures 1-4 As shown, an anti-clogging component is provided inside the grading chamber 1; the anti-clogging component is disposed between the grading screen plate 11 and the clamping plate 12, and is used to apply vibration to the grading screen plate 11; the anti-clogging component includes a connecting column 14 and a jumping plate 141; the connecting column 14 is fixedly disposed inside the grading chamber 1; one end of the jumping plate 141 is rotatably disposed on the connecting column 14; a jumping ball 142 is integrally connected to the jumping plate 141;

[0053] The frame 3 is equipped with a motor assembly for driving the overall vibration of the grading bin 1;

[0054] During operation, in order to prevent the grading screen plate 11 from being clogged by abrasive after long-term operation, an anti-clogging component is installed in the grading chamber 1. The anti-clogging component includes a connecting column 14, a jumping plate 141 and a jumping ball 142, and multiple sets of jumping plates 141 and jumping balls 142 are provided to cover the entire grading screen plate 11. Specifically, a frame 3 is provided at the bottom of the grading chamber 1, and a vibration motor assembly is installed on the frame 3. The vibration motor can be a YZO series vibration motor, and the specific model can be selected according to the actual application.

[0055] During operation, the vibration motor assembly on the frame 3 starts, driving the entire grading chamber 1 to generate high-frequency vibration. Under the action of vibration, since one end of the jumping plate 141 is rotated and set on the connecting column 14, the jumping plate 141 will swing or pry relative to the connecting column 14, thereby driving the jumping ball 142 at the end to generate continuous jumping. Under the jumping of the jumping ball 142, it will repeatedly impact the bottom of the grading screen plate 11, shaking off or pushing out the abrasive particles stuck in the screen holes, thereby effectively preventing the screen holes from clogging. This integrated jumping ball 142 structure has a more stable and controllable movement trajectory and a more concentrated impact force compared to the traditional loosely placed jumping ball 142. Among them, the clamping plate 12 is a hollow plate with holes larger than the screen plate to avoid affecting the flow of abrasive.

[0056] like Figures 6-8 As shown, a side plate 24 is fixedly connected to the side wall of the feeding hopper 21; a telescopic spring 241 is fixedly connected to the side plate 24; an anti-blocking plate 242 is fixedly connected to the end of the telescopic spring 241 away from the side plate 24; the anti-blocking plate 242 and the receiving plate 251 are located below the feeding hopper 211.

[0057] During operation, as the abrasive falls from the feed hopper 211 into the feed bin 21, the falling abrasive continuously impacts the surface of the anti-clogging plate 242. When impacted by the abrasive, the anti-clogging plate 242 elastically retracts relative to the side plate 24 via the telescopic springs 241. Multiple sets of telescopic springs 241 are provided. During the displacement process, the anti-clogging plate 242 continuously changes the channel gap between itself and the receiving plate 251, creating a periodic disturbance and guiding effect on the falling abrasive. This effectively prevents the abrasive from accumulating or bridging between the receiving plate 251 and the anti-clogging plate 242, ensuring the smooth falling of the abrasive within the feed bin 21. Simultaneously, after the impact of the abrasive disappears, the telescopic springs 241 drive the anti-clogging plate 242 to reset, preparing for the next guiding action, thereby achieving a continuous and stable anti-clogging effect.

[0058] like Figure 5 As shown, a pulley 28 is rotatably mounted on the side wall of the feed hopper 21; two sets of pulleys 28 are provided, and the two sets of pulleys 28 are respectively connected to the shaft ends of the magnetic separator 22 and the moving lead screw 261; a connecting belt 281 is sleeved on the pulley 28;

[0059] The feeding hopper 21 has discharge chutes 27 on both sides; the discharge chutes 27 are connected to the discharge ends on both sides of the collection box 23;

[0060] During operation, the magnetic separator 22 and the moving screw 261 are linked by pulleys 28. Two sets of pulleys 28 are provided, which are connected to the shaft end of the magnetic separator 22 and the shaft end of the moving screw 261 respectively. When the external motor drives the magnetic separator 22 to rotate, one set of pulleys 28 at the shaft end of the magnetic separator 22 drives the other set of pulleys 28 at the shaft end of the moving screw 261 to rotate synchronously through the connecting belt 281, thereby driving the moving screw 261 to rotate. When the moving screw 261 rotates, it drives the moving block 262 to move back and forth in the cleaning chamber 26, thereby driving the cleaning push plate 263 to move back and forth in the collection box 23, pushing the metal impurities collected in the collection box 23 to the discharge slides 27 on both sides for discharge, avoiding the accumulation of metal impurities in the feed chamber 21. The moving screw 261 is a reciprocating bidirectional screw structure, which can realize the reciprocating movement of the moving block 262 and the cleaning push plate 263.

[0061] like Figure 3 As shown, the grading sieve plate 11 is inclined from top to bottom, and the aperture of the multiple layers of the grading sieve plate 11 decreases sequentially from top to bottom;

[0062] During operation, multiple sets of grading screen plates 11 are set up. Each set of grading screen plates 11 is equipped with a set of clamping plates 12. The bouncing ball 142 is located between the clamping plate 12 and the grading screen plate 11. After the abrasive falls onto the grading screen plate 11, it is screened sequentially according to the size of the aperture, and finally discharged from the discharge bin 13 corresponding to each area.

[0063] like Figure 2 As shown, a flexible connecting pipe 29 is fixedly connected to the bottom of the feeding hopper 21; the end of the flexible connecting pipe 29 away from the feeding hopper 21 is fixedly connected to the grading hopper 1.

[0064] During operation, the flexible connecting plate can be made of rubber connecting pipe, which can prevent the vibration source from being transmitted from the grading bin 1 to the feeding bin 21.

[0065] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
