Description

Technical Field

[0001] This application relates to the field of workpiece grinding technology, and in particular to a grinding device for recycling abrasives. Background Technology

[0002] Abrasives play a crucial role in workpiece grinding, being one of the key factors determining grinding efficiency and surface finish. To save energy and costs, factories often reuse abrasives; specifically, after a stage of grinding is completed, the used abrasives are processed through recycling equipment, and the processed recycled abrasives are collected and reused in the grinding equipment when the time is right.

[0003] In traditional equipment, the grinding production line and the abrasive processing line are usually two separate departments. Old abrasives need to be manually collected and transferred, and then recycled abrasives need to be manually transferred back to the grinding production line when needed. This not only requires more space in the workshop to accommodate the equipment layout but also increases the difficulty of material handling. Summary of the Invention

[0004] The purpose of this application is to overcome the shortcomings of the existing technology and provide an abrasive recycling grinding device.

[0005] To achieve the above technical objectives, this application provides an abrasive recycling and reusing grinding equipment, comprising: a grinding mechanism capable of loading abrasive and grinding workpieces with the abrasive, wherein a discharge port is provided on the side of the grinding mechanism near the bottom of the grinding chamber; a vibration regeneration mechanism located on one side of the grinding mechanism and below the discharge port, for receiving old abrasive discharged from the discharge port and regenerating the old abrasive to obtain reusable recycled abrasive; a storage and transfer mechanism located downstream of the vibration regeneration mechanism for storing recycled abrasive and unused new abrasive, wherein the inlet of the storage and transfer mechanism is higher than that of the vibration regeneration mechanism; a horizontal feeding mechanism located downstream of the storage and transfer mechanism and above the grinding mechanism for conveying abrasive into the grinding chamber, wherein the horizontal feeding mechanism is higher than the outlet of the storage and transfer mechanism; and a first lifting mechanism. The first lifting mechanism, connected in series with the vibration regeneration mechanism and the storage and transfer mechanism, can receive the regenerated abrasive output from the vibration regeneration mechanism and lift it from a low position to the storage and transfer mechanism located at a high position. The second lifting mechanism, connected in series with the storage and transfer mechanism and the horizontal feeding mechanism, can receive the abrasive output from the storage and transfer mechanism and lift it from a low position to the horizontal feeding mechanism located at a high position. When the abrasive needs to be replaced, the discharge port of the grinding mechanism is opened, the old abrasive enters the vibration regeneration mechanism for regeneration, and the generated regenerated abrasive is lifted and transported by the first lifting mechanism to the storage and transfer mechanism. After the grinding mechanism empties the old abrasive, the storage and transfer mechanism can feed abrasive to the second lifting mechanism. The abrasive is lifted and transported by the second lifting mechanism to the horizontal feeding mechanism, which can feed abrasive into the grinding chamber.

[0006] Furthermore, the grinding mechanism includes: a barrel, the top of which is recessed to form a grinding chamber for loading abrasive, the output end of a horizontal feeding mechanism pointing towards the grinding chamber, and a discharge port located on one side of the barrel and connected to the grinding chamber; a cover plate, which is flip-open and located on one side of the discharge port to cover the discharge port; and a cover-opening drive to drive the cover plate closer to or further away from the discharge port. When the cover plate is close to the discharge port, it can block the discharge port and prevent the abrasive from leaking out of the barrel. When the cover plate is away from the discharge port, the discharge port is open, and the abrasive can leave the barrel through the discharge port.

[0007] Furthermore, the grinding mechanism also includes a grinding vibrator, which is used to drive the barrel to reciprocate. When grinding the workpiece, the discharge port is closed, and the barrel vibrates under the drive of the grinding vibrator. The abrasive in the barrel comes into contact with the workpiece under the action of vibration, thus grinding the workpiece. When changing the abrasive, the discharge port is opened, and the barrel vibrates under the drive of the grinding vibrator. The abrasive in the barrel is discharged through the discharge port under the action of vibration.

[0008] Furthermore, the vibration regeneration mechanism includes: a trough for receiving old abrasive discharged from the grinding mechanism; a sieve plate suspended inside the trough for filtering out impurities and substandard abrasive; a regeneration vibrator for driving the trough to vibrate reciprocally; and a flushing assembly located above the trough for spraying an aqueous solution into the trough to flush the old abrasive and prevent it from accumulating inside. The trough has a waste outlet at its bottom and a regenerated material outlet on the side of the trough away from the discharge port, directly above the receiving end of the first lifting mechanism. When replacing the abrasive, the discharge port opens, allowing the old abrasive to fall into the trough and onto the sieve plate under its own weight. Driven by the regeneration vibrator, the trough vibrates, and the old abrasive continuously collides and grinds against the sieve plate. Impurities mixed in the old abrasive, as well as substandard abrasive with non-compliant particle sizes, pass through the sieve plate and fall to the bottom of the trough, ultimately being discharged through the waste outlet. Qualified abrasive vibrates and feeds towards the regenerated material outlet on the sieve plate, eventually being discharged into the first lifting mechanism.

[0009] Furthermore, a first receiving chute is provided between the discharge port and the trough, the first receiving chute extending downward toward the trough, so that the old abrasive discharged through the discharge port can slide along the first receiving chute toward the trough; and / or, a second receiving chute is provided between the recycled material outlet and the first lifting mechanism, the second receiving chute extending downward toward the first lifting mechanism, so that the recycled abrasive discharged through the recycled material outlet can slide along the second receiving chute toward the first lifting mechanism.

[0010] Furthermore, the storage and transfer mechanism includes a material frame for loading abrasives; the top of the material frame has a feed inlet, and the discharge end of the first lifting mechanism is directly opposite the feed inlet, allowing the abrasives to be fed into the material frame through the feed inlet; the bottom of the material frame has a discharge outlet, which is directly opposite the receiving end of the second lifting mechanism, allowing the abrasives to leave the material frame and enter the second lifting mechanism through the discharge outlet; a valve is provided on the discharge outlet, and when the valve is open, the abrasives in the material frame can pass through the discharge outlet, and when the valve is closed, the abrasives in the material frame cannot pass through the discharge outlet.

[0011] Furthermore, a quantitative feeding mechanism is provided at the discharge port of the material frame, which is used to control the discharge amount of the storage and transfer mechanism.

[0012] Further, the first lifting mechanism and / or the second lifting mechanism include: a conveying support frame, which includes a transverse bottom mounting plate, a transverse top mounting plate, and an inclined extension plate. The transverse bottom mounting plate is located below the storage and transfer mechanism and faces the discharge port. The transverse top mounting plate is located diagonally above the transverse bottom mounting plate and points towards the horizontal feeding mechanism. The inclined extension plate is used to connect the transverse bottom mounting plate and the transverse top mounting plate. Multiple sets of pulleys are rotatably mounted on the conveying support frame, and the multiple sets of pulleys are spaced apart on the transverse bottom mounting plate, the transverse top mounting plate, and the inclined extension plate. A conveyor belt is wound around the multiple sets of pulleys. After the abrasive leaves the storage and transfer mechanism through the discharge port, it falls onto the conveyor belt and is then lifted and conveyed by the conveyor belt towards the horizontal feeding mechanism.

[0013] Furthermore, the surface of the conveyor belt that contacts the abrasive is provided with a mesh receiving structure, so that the abrasive can enter the mesh receiving structure after falling into the conveyor belt, thereby preventing the abrasive from falling off during the conveyor belt's uphill process; and / or, along the extension direction of the conveyor belt, multiple receiving plates are spaced apart on the surface of the conveyor belt that contacts the abrasive, and the receiving plates are set at an angle on the conveyor belt, so that when the conveyor belt climbs the slope, the receiving plates can block the abrasive and prevent the abrasive from falling off.

[0014] Furthermore, the horizontal feeding mechanism uses a conveyor belt.

[0015] This application provides an abrasive recycling and regeneration grinding device, including a grinding mechanism, a vibration regeneration mechanism, a storage and transfer mechanism, a horizontal feeding mechanism, a first lifting mechanism, and a second lifting mechanism. The vibration regeneration mechanism is used to receive the old abrasive discharged from the grinding mechanism and can regenerate the old abrasive. The storage and transfer mechanism is located downstream of the vibration regeneration mechanism and is used to store regenerated abrasive and unused new abrasive. The horizontal feeding mechanism is located downstream of the storage and transfer mechanism and above the grinding mechanism, and is used to convey abrasive to the grinding mechanism. To meet the needs of different mechanisms, the grinding mechanism, the vibration regeneration mechanism, and the storage and transfer mechanism are arranged at different heights. The first lifting mechanism is connected in series with the vibration regeneration machine. The first and second lifting mechanisms are connected in series with the storage and transfer mechanism, which can receive the regenerated abrasive output from the vibration regeneration mechanism and lift it from a low position to a high position in the storage and transfer mechanism. The second lifting mechanism can receive the abrasive output from the storage and transfer mechanism and lift it from a low position to a high position in the horizontal feeding mechanism. The abrasive recycling grinding equipment provided by this application can quickly and reliably collect old abrasive and regenerate it, and can also collect the regenerated abrasive that has completed the regeneration process at the same time, and provide a fast and reliable abrasive supply as needed. The whole set of equipment has a ring layout, which has a small footprint, high conveying efficiency, and strong applicability. Attached Figure Description

[0019] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0020] This application provides an abrasive recycling grinding device, comprising: a grinding mechanism 100, capable of loading abrasive and grinding workpieces with the abrasive, the grinding mechanism 100 having a discharge port on one side near the bottom of the grinding chamber; a vibration regeneration mechanism 200, located on one side of the grinding mechanism 100 and below the discharge port, for receiving old abrasive discharged from the discharge port and regenerating the old abrasive to obtain reusable recycled abrasive; a storage and transfer mechanism 300, located downstream of the vibration regeneration mechanism 200, for storing recycled abrasive and unused new abrasive, the inlet of the storage and transfer mechanism 300 being higher than the vibration regeneration mechanism 200; a horizontal feeding mechanism 400, located downstream of the storage and transfer mechanism 300 and above the grinding mechanism 100, for conveying abrasive into the grinding chamber, the horizontal feeding mechanism 400 being higher than the outlet of the storage and transfer mechanism 300; and a first lifting mechanism 510, connected in series with the vibration regeneration mechanism 200 and the... The storage and transfer mechanism 300 can receive the regenerated abrasive output from the vibration regeneration mechanism 200 and lift the regenerated abrasive from a low position into the storage and transfer mechanism 300 located at a high position. The second lifting mechanism 520 is connected in series with the storage and transfer mechanism 300 and the horizontal feeding mechanism 400. It can receive the abrasive output from the storage and transfer mechanism 300 and lift the abrasive from a low position into the horizontal feeding mechanism 400 located at a high position. When the abrasive needs to be replaced, the discharge port of the grinding mechanism 100 is opened, the old abrasive enters the vibration regeneration mechanism 200 for regeneration, and the generated regenerated abrasive is lifted and conveyed by the first lifting mechanism 510 into the storage and transfer mechanism 300. After the grinding mechanism 100 empties the old abrasive, the storage and transfer mechanism 300 can feed the abrasive to the second lifting mechanism 520. The abrasive is lifted and conveyed by the second lifting mechanism 520 into the horizontal feeding mechanism 400, and the horizontal feeding mechanism 400 feeds the abrasive into the grinding chamber.

[0021] For details, please refer to Figures 1 to 3 In the illustrated embodiment, the grinding chamber is an open cavity within the grinding mechanism 100 used to load abrasive and place workpieces. To accommodate workpiece placement and abrasive movement, the grinding chamber has a large volume. Simultaneously, the grinding chamber needs to be suspended relative to the ground to facilitate vibration; therefore, the grinding mechanism 100 has a considerable height. Positioning the discharge port near the bottom of the chamber also facilitates the outflow of abrasive from within the grinding chamber.

[0022] Continue to refer to Figure 1 and Figure 2To facilitate the collection of abrasive discharged from the grinding chamber, the vibration regeneration mechanism 200 has a relatively small height. Located below the discharge port, the abrasive discharged through the discharge port can actively fall into the vibration regeneration mechanism 200 under its own weight. Since the storage and transfer mechanism 300 needs to hold at least as much material as the grinding mechanism 100, its material frame 310 also has a large volume. For convenient feeding, the top of the material frame 310 is open, serving as the feed inlet for the storage and transfer mechanism 300.

[0023] Some of the old abrasives are damaged and unusable due to long-term use. The vibration regeneration mechanism 200 will remove these unusable abrasives during the regeneration process. This results in the amount of regenerated abrasives output by the vibration regeneration mechanism 200 being less than the material requirement of the grinding mechanism 100.

[0024] Therefore, in addition to receiving recycled abrasive, the storage and transfer mechanism 300 can also receive unused new abrasive. The new abrasive can be manually transported and put into the storage and transfer mechanism 300, or other mechanical transport equipment similar to the first lifting mechanism 510 and the second lifting mechanism 520 can be set up to put the new abrasive into the storage and transfer mechanism 300.

[0025] Continue to refer to Figure 3 To facilitate the output of abrasive from the storage and transfer mechanism 300, the discharge port of the storage and transfer mechanism 300 is located at the bottom of its material frame 310. In this way, when the discharge port is open, the abrasive can actively fall off the material frame 310.

[0026] Continue to refer to Figure 3 To facilitate material feeding and workpiece placement, the top of the grinding mechanism 100's cylinder 110 is open, and the horizontal feeding mechanism 400 is located above the cylinder 110 and extends towards the center of the cylinder 110. The horizontal feeding mechanism 400 is positioned high, and after receiving the abrasive, it can transport the abrasive to the grinding chamber.

[0027] In summary, in order to meet the needs of different mechanisms, the grinding mechanism 100, the vibration regeneration mechanism 200, and the storage and transfer mechanism 300 are arranged at different heights.

[0028] To facilitate the flow of abrasive between different mechanisms, a first lifting mechanism 510 and a second lifting mechanism 520 are provided to lift the abrasive. Unlike the linear transport of the horizontal feeding mechanism 400, the first lifting mechanism 510 and the second lifting mechanism 520 can lift the abrasive from a low position to a high position after receiving it, so that the abrasive can be fed into the downstream mechanism.

[0029] The first lifting mechanism 510 and the second lifting mechanism 520 can be any mechanism capable of overcoming height differences to transport abrasive materials, such as a bucket elevator or a pneumatic conveying tank.

[0030] The abrasive recycling and grinding equipment provided in this application can quickly and reliably collect old abrasives and regenerate them, while simultaneously collecting regenerated abrasives that have undergone regeneration and providing a fast and reliable abrasive supply as needed. The entire equipment has a ring-shaped layout, small footprint, high conveying efficiency, and strong applicability.

[0031] In one specific embodiment, the grinding mechanism 100 includes: a material cylinder 110, the top of which is recessed to form a grinding cavity for loading abrasive, the output end of a horizontal feeding mechanism 400 pointing towards the grinding cavity, and a discharge port located on one side of the material cylinder 110 and communicating with the grinding cavity; a cover plate 120, which is flip-mounted on one side of the discharge port for covering the discharge port; and a cover-flipping drive member 130 for driving the cover plate 120 closer to or further away from the discharge port. When the cover plate 120 is close to the discharge port, it can block the discharge port and prevent the abrasive in the material cylinder 110 from leaking out; when the cover plate 120 is away from the discharge port, the discharge port is open, and the abrasive can leave the material cylinder 110 through the discharge port.

[0032] The flip-top drive unit 130 can be a linear drive structure such as a cylinder or electric cylinder that is rotatably connected to the cover plate 120, which can reduce the stroke difference and achieve flipping by its own rotation; or it can be a rotary drive structure such as a rotary cylinder or motor that is connected to the rotating shaft where the cover plate 120 is located, which can drive the rotating shaft to rotate and drive the cover plate 120 on the rotating shaft to flip accordingly.

[0033] By setting a flip-up cover plate 120, the controllable and automated opening and closing of the discharge port is achieved.

[0034] Furthermore, the grinding mechanism 100 also includes a grinding vibrator 140, which is used to drive the grinding cylinder 110 to reciprocate. When grinding the workpiece, the discharge port is closed, and the grinding cylinder 110 vibrates under the drive of the grinding vibrator 140. The abrasive in the grinding cylinder 110 comes into contact with the workpiece under the action of vibration and grinds the workpiece. When changing the abrasive, the discharge port is opened, and the grinding cylinder 110 vibrates under the drive of the grinding vibrator 140. The abrasive in the grinding cylinder 110 is discharged through the discharge port under the action of vibration.

[0035] It can be added that the barrel 110 can be equipped with only one grinding vibrator 140 for unidirectional vibration, or multiple grinding vibrators 140 can be installed. If multiple grinding vibrators 140 are arranged in the same direction, the unidirectional vibration effect can be enhanced. If multiple grinding vibrators 140 are arranged in opposite directions, the abrasive in the barrel 110 can move along a complex path, thereby meeting more diverse grinding needs.

[0036] In one embodiment, the vibration regeneration mechanism 200 includes: a feed trough 210 for receiving used abrasive material discharged from the grinding mechanism 100; a sieve plate 220 suspended within the feed trough 210 for filtering out impurities and substandard abrasive material; a regeneration vibrator 230 for driving the feed trough 210 to reciprocate; and a flushing assembly disposed above the feed trough 210 for spraying an aqueous solution into the feed trough 210 to flush the used abrasive material and prevent it from accumulating within the feed trough 210; wherein, a waste outlet is provided at the bottom of the feed trough 210; and a recycled material outlet is provided on the side of the feed trough 210 away from the discharge port. Located directly above the receiving end of the first lifting mechanism 510; when replacing the abrasive, the discharge port opens, and the old abrasive can fall into the trough 210 and onto the screen plate 220 under its own weight. Driven by the regeneration vibrator 230, the trough 210 vibrates, and the old abrasive collides and grinds continuously with the screen plate 220; impurities mixed in the old abrasive and unqualified abrasive with particle sizes that do not meet the specifications pass through the screen plate 220 and fall into the bottom of the trough 210, and are finally discharged through the waste outlet; qualified abrasive vibrates and feeds towards the regenerated material outlet on the screen plate 220, and is finally discharged into the first lifting mechanism 510.

[0037] The rinsing component can be any structure capable of spraying water onto the abrasive, such as a water pipe or a nozzle. Depending on the regeneration requirements, the liquid sprayed by the rinsing component can be clean water or a chemical reagent solution with cleaning properties.

[0038] Specifically, the regeneration vibrator 230 drives the feed trough 210 to vibrate reciprocally. After the old abrasive enters the feed trough 210, it bounces and falls repeatedly under the vibration. During this process, the abrasive particles collide and grind against each other and against the sieve plate 220, thus removing impurities and chemical reagents adhering to the surface of the abrasive. Simultaneously, the flushing component continuously sprays solution into the feed trough 210. The solution impacts the old abrasive, further cleaning it. The downward-flowing water also helps impurities and small-diameter defective abrasive particles fall through the sieve holes of the sieve plate 220, preventing clogging. The feed trough 210 has a certain length, allowing the abrasive to vibrate and regenerate within it while simultaneously being fed towards the regenerated material outlet. During this vibratory feeding process, the abrasive undergoes long-distance vibration regeneration and flushing, ensuring effective regeneration. Ultimately, qualified recycled abrasive is discharged through the recycled material outlet, while impurities and unqualified abrasive are fed along the bottom of the material trough 210 via vibration and are finally discharged through the waste material outlet.

[0039] Optionally, a first receiving groove is provided between the discharge port and the trough 210. The first receiving groove extends downward toward the trough 210, and the old abrasive discharged through the discharge port can slide along the first receiving groove toward the trough 210.

[0040] Optionally, a second receiving chute is provided between the recycled material outlet and the first lifting mechanism 510. The second receiving chute extends downward toward the first lifting mechanism 510, and the recycled abrasive discharged through the recycled material outlet can slide along the second receiving chute toward the first lifting mechanism 510.

[0041] The first and second receiving chutes are both designed as slides with side rails on both sides, which can effectively receive the abrasive and guide it to move towards the downstream mechanism located at a lower position.

[0042] In one embodiment, the storage and transfer mechanism 300 includes a material frame 310 for loading abrasives; the top of the material frame 310 is provided with a feed inlet, and the discharge end of the first lifting mechanism 510 is directly opposite the feed inlet, allowing the abrasives to be fed into the material frame 310 through the feed inlet; the bottom of the material frame 310 is provided with a discharge outlet, which is directly opposite the receiving end of the second lifting mechanism 520, allowing the abrasives to leave the material frame 310 and enter the second lifting mechanism 520 through the discharge outlet; a valve 320 is provided on the discharge outlet, allowing the abrasives in the material frame 310 to pass through the discharge outlet when the valve 320 is open, and preventing the abrasives in the material frame 310 from passing through the discharge outlet when the valve 320 is closed.

[0043] Among them, valve 320 can be any valve structure that can control the opening of the discharge port, such as plate valve, gate valve, check valve, etc. It can be an automatic valve or a manually controlled driven valve.

[0044] Specifically, when the grinding mechanism 100 needs to be replaced with abrasive after completing the first stage of grinding, valve 320 is still closed. After the old abrasive in the grinding mechanism 100 has been discharged, if no additional cleaning or maintenance of the grinding mechanism 100 is required, the discharge port of the grinding mechanism 100 can be closed, valve 320 opened, and the second lifting mechanism 520 started. In this way, the abrasive in the material frame 310 can fall into the second lifting mechanism 520 and then be conveyed towards the grinding mechanism 100 by the second lifting mechanism 520. After the grinding mechanism 100 has finished filling, valve 320 is closed, and the material frame 310 can continue to store regenerated abrasive and new abrasive as a storage bin.

[0045] In other words, the abrasive recycling and grinding equipment provided in this application allows for the simultaneous regeneration of old abrasives and the feeding of materials into the grinding mechanism 100.

[0046] Optionally, a quantitative feeding mechanism is provided at the discharge port of the material frame 310, which is used to control the discharge amount of the storage and transfer mechanism 300.

[0047] In one embodiment, the quantitative feeding mechanism is a quantitative valve.

[0048] Specifically, when the metering valve is opened, the abrasive can flow into the second lifting mechanism 520 through the discharge port. When the abrasive flows out for a preset time or the outflow amount of the abrasive reaches a preset value, the metering valve is closed.

[0049] In another embodiment, the quantitative feeding mechanism is a vibrating feeder.

[0050] Specifically, the abrasive in the material frame 310 can flow into the vibrating feeder; when the vibrating feeder is started, it can vibrate and feed the abrasive, thereby driving the abrasive to flow to the second lifting mechanism 520; after the vibration is preset for a preset time or the abrasive is fed a preset amount, the vibrating feeder is turned off.

[0051] In another embodiment, the quantitative feeding mechanism is a screw feeder.

[0052] Specifically, the spiral feeder includes a cylinder and spiral blades. The spiral blades are rotatably disposed in the cylinder, which is connected to the material frame 310 and the second lifting mechanism 520. The abrasive in the material frame 310 can enter the cylinder. When the spiral feeder is started, the spiral blades rotate, which can promote the spiral feeding of the abrasive in the cylinder to the second lifting mechanism 520. After the spiral blades rotate for a preset time or feed a preset amount of abrasive, the spiral feeder is turned off and the spiral blades stop rotating.

[0053] This application does not limit the specific configuration of the quantitative feeding mechanism.

[0054] The quantitative feeding mechanism can control the output of the storage and transfer mechanism 300, and thus control the amount of material fed to the grinding mechanism 100 by the second lifting mechanism 520 and the horizontal feeding mechanism 400. This is beneficial for the quantitative output of abrasive and can also improve the feeding accuracy of abrasive.

[0055] In one specific embodiment, the first lifting mechanism 510 and / or the second lifting mechanism 520 include: a conveying support frame, which includes a transverse bottom mounting plate 511, a transverse top mounting plate 512, and an inclined extension plate 513. The transverse bottom mounting plate 511 is located below the storage transfer mechanism 300 and faces the discharge port. The transverse top mounting plate 512 is located diagonally above the transverse bottom mounting plate 511 and points towards the horizontal feeding mechanism 400. The inclined extension plate 513 is used to connect the transverse bottom mounting plate 511 and... A transverse top mounting plate 512; multiple sets of pulleys 514, any one of which is rotatably mounted on the conveyor support frame, and the multiple sets of pulleys 514 are spaced apart on the transverse bottom mounting plate 511, the transverse top mounting plate 512 and the inclined extension plate 513; a conveyor belt 515, which is wound around the multiple sets of pulleys 514; after the abrasive leaves the storage and transfer mechanism 300 through the discharge port, it will fall onto the conveyor belt 515, and then be lifted and conveyed by the conveyor belt 515 to move toward the horizontal feeding mechanism 400.

[0056] For details, please refer to Figure 2 and Figure 3 In the illustrated embodiment, the conveyor support frame is roughly zigzag-shaped, including two horizontally extending buffer sections (i.e., the horizontal bottom mounting plate 511 and the horizontal top mounting plate 512) and an inclined extending connecting section (i.e., the inclined extension plate 513), which is conducive to stable material receiving, smooth lifting and stable material discharge.

[0057] Continue to refer to Figure 2 and Figure 3 A set of transverse bottom mounting plates 511, transverse top mounting plates 512, and inclined extension plates 513 are integrally formed to constitute a support plate; the conveyor support frame is composed of two sets of support plates arranged side by side. Pulleys 514 are disposed between the two sets of support plates; any one of the pulleys 514 is rotatably mounted on the support plate via bearings; the conveyor belt 515 extends circumferentially along the conveyor support frame and is supported, tensioned, and driven by the pulleys 514.

[0058] The first lifting mechanism 510 and / or the second lifting mechanism 520 also include a lifting drive component. The lifting drive component can be a rotary cylinder, motor or other rotary drive component. The lifting drive component is used to drive at least one pulley 514 to rotate actively, and then realize the circulation of the conveyor belt 515 through the transmission of the conveyor belt 515 and other pulleys 514.

[0059] Optionally, to prevent the abrasive material entering the first lifting mechanism 510 or the second lifting mechanism 520 from falling off the conveyor belt 515, the conveyor belt 515 is provided with two sets of guard plates. The two sets of guard plates are spaced apart along the width direction of the conveyor belt 515, which can prevent the abrasive material from falling off the conveyor belt 515 from both sides.

[0060] Optionally, the surface of the conveyor belt 515 that contacts the abrasive is provided with a mesh receiving structure. After the abrasive falls into the conveyor belt 515, it can enter the mesh receiving structure, thereby preventing the abrasive from falling off during the incline of the conveyor belt 515.

[0061] Optionally, along the extension direction of the conveyor belt 515, a plurality of receiving plates are spaced apart on the surface of the conveyor belt 515 that is in contact with the abrasive. The receiving plates are arranged at an angle on the conveyor belt 515. When the conveyor belt 515 climbs an incline, the receiving plates can block the abrasive and prevent the abrasive from falling off.

[0062] It is easy to understand that when abrasive material is climbing an incline with the conveyor belt 515, it cannot climb the incline without sufficient support and may accumulate at corners or detach from the conveyor belt 515. Providing a mesh receiving structure to accommodate the abrasive material or a receiving plate to support it on the surface of the conveyor belt 515 can support the abrasive material as it climbs the incline. Simultaneously, since both the mesh receiving structure and the receiving plate are open structures, when the conveyor belt 515 moves to the end of the transverse top mounting plate 512 and changes direction, the abrasive material on the mesh receiving structure or the receiving plate can naturally detach from the conveyor belt 515 and fall into the horizontal feeding mechanism 400.

[0063] In one embodiment, the horizontal feeding mechanism 400 uses a conveyor belt.

[0064] For details, please refer to Figure 3 In the illustrated embodiment, the horizontal feeding mechanism 400 is suspended above the grinding mechanism 100 and extends along a straight line from the second lifting mechanism 520 to the open top of the grinding chamber. The input end of the horizontal feeding mechanism 400 is located directly below the discharge end of the second lifting mechanism 520, and the output end is located directly above the grinding chamber. After the abrasive moves along the conveyor belt 515 to the end of the transverse top mounting plate 512, as the conveyor belt 515 changes direction, the abrasive will actively fall onto the horizontal feeding mechanism 400. The conveyor belt of the horizontal feeding mechanism 400 flows towards the grinding chamber, which can drive the abrasive into the grinding chamber. If the abrasive output of the storage and transfer mechanism 300 is greater than the material demand of the grinding mechanism 100, the horizontal feeding mechanism 400 is stopped in advance. The horizontal feeding mechanism 400 can also temporarily store the excess abrasive, and start the conveying again for the next feeding.

[0065] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
