Description

Technical Field

[0001] This application relates to the field of workpiece grinding technology, and in particular to an abrasive regeneration processing mechanism and grinding equipment. Background Technology

[0002] Abrasives, as recyclable materials, play a crucial role in workpiece grinding, and their recycling helps save costs. After the first stage of grinding, the abrasive needs to undergo regeneration to ensure it meets subsequent usage specifications.

[0003] Abrasive regeneration is a complex process, and conventional abrasive regeneration equipment is large and cumbersome to operate. The regeneration process includes multiple steps such as cleaning, drying, and sieving. Cleaning removes impurities and dust from the abrasive surface; drying ensures the abrasive is dry to prevent moisture from affecting its performance; and sieving sorts the abrasive according to its particle size for later use. However, this process is time-consuming, labor-intensive, and costly. Summary of the Invention

[0004] The purpose of this application is to overcome the shortcomings of the existing technology and provide an abrasive regeneration processing mechanism and grinding equipment.

[0005] To achieve the above technical objectives, this application provides an abrasive regeneration processing mechanism, comprising: a trough for receiving used abrasives; a sieve plate suspended in the trough for filtering out impurities and substandard abrasives; and a vibrator for driving the trough to reciprocate. During abrasive regeneration, the used abrasives enter the trough and fall onto the sieve plate. Driven by the vibrator, the trough vibrates, and the used abrasives continuously collide and grind with the sieve plate. Impurities mixed in the used abrasives, as well as substandard abrasives with particle sizes that do not meet specifications, pass through the sieve plate.

[0006] Furthermore, the feed trough is equipped with a waste outlet, so that impurities and substandard abrasives can be discharged through the waste outlet after passing through the screen plate and falling to the bottom of the feed trough.

[0007] Furthermore, the bottom of the trough is inclined and extended, and the waste outlet is located on the downslope. After impurities and substandard abrasives fall into the bottom of the trough, they can slide along the slope toward the waste outlet.

[0008] Furthermore, the material trough is equipped with two sets of screen plates, which are arranged in layers along the extension direction of the material trough, with the set of screen plates near the qualified material outlet in a lower position.

[0009] Furthermore, the screen plate is detachably installed in the trough.

[0010] Furthermore, a receiving chute is provided at the qualified material outlet of the trough, and qualified abrasive moves along the screen plate toward the receiving chute and finally enters the receiving chute.

[0011] Furthermore, the further away from the sieve plate, the smaller the diameter of the receiving chute, in order to gather qualified abrasive and guide it towards the downstream mechanism.

[0012] Furthermore, the receiving chute is inclined downwards in a direction away from the screen plate, so that qualified abrasive entering the receiving chute can actively slide towards the downstream mechanism.

[0013] Furthermore, the abrasive regeneration processing mechanism also includes a spraying mechanism, which is used to spray water onto the feed trough. The water spraying can both wash the abrasive and prevent the abrasive from accumulating in the feed trough.

[0014] This application also provides a grinding device, including the above-mentioned abrasive regeneration processing mechanism, and a grinding mechanism, which is capable of loading abrasive and grinding workpieces with the abrasive; the regeneration processing mechanism is located downstream of the grinding mechanism, for receiving used abrasive from the grinding mechanism, and is capable of regenerating the used abrasive.

[0015] This application provides an abrasive regeneration processing mechanism, including a feed trough, a sieve plate, and a vibrator. The sieve plate is suspended inside the feed trough, and the vibrator drives the feed trough to vibrate reciprocally. During abrasive regeneration, old abrasive enters the feed trough and falls onto the sieve plate. Driven by the vibrator, the feed trough vibrates, and the old abrasive continuously collides and grinds with the sieve plate, promoting the regeneration of the old abrasive. Qualified abrasive can vibrate and feed along the sieve plate towards the qualified material outlet, while impurities mixed in the old abrasive and unqualified abrasive with particle sizes that do not meet specifications pass through the sieve plate and fall to the bottom of the feed trough. The abrasive regeneration processing mechanism provided by this application can achieve rapid screening of qualified and unqualified materials, with high processing efficiency. The abrasive can also be actively discharged through vibration feeding. The multi-functionality is integrated into one unit, making the overall size of the regeneration mechanism small and its applicability good. The abrasive regeneration effect is good, and the abrasive quality is guaranteed. The high regeneration efficiency is conducive to improving production efficiency. Attached Figure Description

[0017] Figure 2 This is a schematic diagram of a grinding device provided in this application. Detailed Implementation

[0018] 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.

[0019] This application provides an abrasive regeneration processing mechanism 10, including: a material trough 11 for receiving used abrasives; a sieve plate 12 suspended in the material trough 11 for filtering out impurities and unqualified abrasives; and a vibrator 13 for driving the material trough 11 to reciprocate. During abrasive regeneration, the used abrasives enter the material trough 11 and fall onto the sieve plate 12. Driven by the vibrator 13, the material trough 11 vibrates, and the used abrasives continuously collide and grind with the sieve plate 12. Impurities mixed in the used abrasives and unqualified abrasives with particle sizes that do not meet specifications pass through the sieve plate 12.

[0020] For details, please refer to Figure 1 In the illustrated embodiment, the main body of the material trough 11 is square and has a certain length; the top of the material trough 11 is open so that old abrasive can be fed into the material trough 11 from top to bottom; the right and front ends of the material trough 11 are open and serve as the outlet for qualified material.

[0021] Continue to refer to Figure 1 The abrasive regeneration processing mechanism 10 also includes a base 16. A feed trough 11 is mounted on the base 16 via an elastic shock absorber, and the feed trough 11 is supported above the ground via the base 16. A vibrator 13 is located below the feed trough 11, and the vibrator 13 is inclined downward toward the qualified material outlet. When regenerating abrasive, the vibrator 13 is activated, which drives the feed trough 11 to vibrate back and forth along the inclined direction. In this way, the abrasive can be vibrated and fed toward the qualified material outlet.

[0022] Continue to refer to Figure 1 A sieve plate 12 is suspended in the feed trough 11. The sieve plate 12 has sieve holes. After the old abrasive is put into the feed trough 11, it will fall onto the sieve plate 12.

[0023] In one specific embodiment, during abrasive regeneration, the old abrasive falls onto the sieve plate 12, and the feed trough 11 vibrates reciprocally, causing the abrasive to continuously rise and fall. During the vibration process, the abrasive continuously impacts and grinds against each other and against the sieve plate 12, thereby removing impurities such as abrasive chips and chemical reagents adhering to the abrasive surface, thus regenerating the abrasive. Impurities mixed in the abrasive, as well as substandard abrasive that has become smaller or even deformed due to prolonged use, will pass through the sieve holes, through the sieve plate 12, and fall to the bottom of the feed trough 11. Meanwhile, qualified abrasive will vibrate and be fed forward along the feed trough 11. The length design of the feed trough 11 and the sieve plate 12 can extend the vibration path and increase the number of vibrations, thereby ensuring the regeneration effect of the abrasive. Finally, the qualified abrasive is discharged from the feed trough 11 through the qualified material outlet.

[0024] The abrasive regeneration processing mechanism 10 provided in this application collects old abrasive through a trough 11, and uses the combined action of a sieve plate 12 and a vibrator 13 to promote the regeneration of old abrasive, realizing rapid screening of qualified and unqualified materials and improving processing efficiency; at the same time, through the vibration feeding method, qualified materials also have the function of active discharge during the regeneration process, which is convenient and practical; the multi-functionality is integrated into one, making the overall size of the regeneration mechanism small and the applicability good; the abrasive regeneration effect is good, the abrasive quality is guaranteed; the regeneration efficiency is high, which is conducive to improving production efficiency.

[0025] The abrasive regeneration processing device provided in this application integrates collection, regeneration, screening, and discharge functions into one unit, offering advantages such as small size, good effect, and high efficiency, thus providing a new solution for abrasive regeneration processing.

[0026] As described above, during the abrasive regeneration process, impurities and substandard abrasives pass through the sieve plate 12 and fall to the bottom of the feed trough 11. Since the sieve plate 12 is suspended in the feed trough 11, there is a certain storage space below the sieve plate 12, which can accommodate a certain amount of impurities and substandard abrasives.

[0027] In one embodiment, staff or relevant mechanical equipment can periodically or as needed clean the impurities and substandard abrasives accumulated in the storage space.

[0028] In another embodiment, the feed trough 11 is provided with a waste outlet 14. Impurities and substandard abrasives pass through the sieve plate 12, fall into the bottom of the feed trough 11, and can be discharged through the waste outlet 14.

[0029] For details, please refer to Figure 1 In the illustrated embodiment, the waste outlet 14 is located on one side of the feed trough 11 and close to the qualified material outlet of the feed trough 11. Thus, during the regeneration of abrasive, the feed trough 11 vibrates, and the qualified abrasive on the screen plate 12 vibrates and feeds towards the qualified material outlet, while the impurities and unqualified materials under the screen plate 12 vibrate and feed towards the waste outlet 14.

[0030] This configuration allows for the rapid discharge of materials from the trough 11, improving the efficiency of waste treatment and ensuring that the abrasive regeneration processing mechanism 10 can operate continuously and efficiently.

[0031] Optionally, the bottom of the trough 11 is inclined and extended, and the waste outlet 14 is located at the downslope. After impurities and unqualified abrasives fall into the bottom of the trough 11, they can slide along the slope toward the waste outlet 14.

[0032] Specifically, the bottom of the material trough 11 is inclined downward toward the waste outlet 14. After impurities and unqualified abrasives fall into the bottom of the trough, they can actively and quickly slide along the slope toward the waste outlet 14 under their own weight.

[0033] This design ensures that material does not accumulate at the bottom of the feed trough 11 and remains unobstructed, thus preventing material accumulation from affecting the vibration and regeneration of the abrasive particles by the screen plate 12. The inclined bottom design and the optimal location of the waste outlet 14 enable rapid discharge of impurities and substandard abrasive particles, improving the flowability of the feed trough.

[0034] Optionally, the feed trough 11 is provided with two sets of screen plates 12. Along the extension direction of the feed trough 11, the two sets of screen plates 12 are arranged in layers, with the set of screen plates 12 near the qualified material outlet being in a lower position.

[0035] For details, please refer to Figure 1 In the illustrated embodiment, a set of sieve plates 12 positioned on the left and rear is at a higher position, while another set of sieve plates 12 adjacent to it is at a lower position. Old abrasive is fed into the feed trough 11 from the upper left, initially falling onto the higher set of sieve plates 12. As the abrasive vibrates and feeds to the right towards the qualified material outlet, it is vibrated up by the higher sieve plate and falls onto the lower sieve plate. By arranging the two sets of sieve plates 12 in a tiered manner, the height difference increases the impact force of the falling abrasive, further promoting abrasive regeneration and optimizing the regeneration effect.

[0036] Continue to refer to Figure 1 The two sets of sieve plates 12 have an overlapping portion at one end, which effectively prevents qualified abrasive from falling below the sieve plate 12 due to the gap between the two sets of sieve plates 12. The overlapping portion also enhances the structural stability of the sieve plate 12, making it less susceptible to damage under vibration and abrasive impact.

[0037] Optionally, the sieve plate 12 is detachably disposed in the feed trough 11.

[0038] For example, Figure 1 In the illustrated embodiment, support bars are provided on the walls of the trough 11 on both sides in the width direction. These support bars are used to place the screen plate 12. When installing the screen plate 12, it is placed on the support bars, which support the screen plate 12 above the bottom of the trough 11. Multiple inverted L-shaped fixing bars 17a are provided on both sides of the screen plate 12, and multiple clamping handles 17b are provided on the top of both sides of the trough 11. After the screen plate 12 is placed into the trough 11, the inverted L-shaped fixing bars 17a and clamping handles 17b correspond one-to-one. By forcefully rotating the clamping handles 17b downwards, the clamping handles 17b can press against the inverted L-shaped fixing bars 17a, thereby cooperating with the support bars to secure the screen plate 12 in the trough 11. When it is necessary to replace the screen plate 12, force is applied in the opposite direction, and the clamping handles 17b are rotated upwards. The clamping handles 17b can loosen the inverted L-shaped fixing bars 17a, releasing the fixing force on the screen plate 12, allowing for easy removal of the screen plate 12.

[0039] In other embodiments, the sieve plate 12 and the material trough 11 can be detachably connected by means of snap-fit, plug-in, screw-fit, etc.

[0040] The screen plate 12 is detachably installed in the feed trough 11, and the screen plate 12 with different mesh sizes can be replaced according to the type and specifications of the abrasive to facilitate the screening of abrasives of different particle sizes; the screen plate 12 can also be cleaned regularly or as needed to prevent the screen plate 12 from being damaged or blocked during the recycling process.

[0041] Optionally, a receiving chute 15 is provided at the qualified material outlet of the material trough 11. Qualified abrasive moves along the screen plate 12 toward the receiving chute 15 and finally enters the receiving chute 15.

[0042] The receiving chute 15 is used to receive qualified abrasive that has been recycled. In one embodiment, the receiving chute 15 has a certain volume and can store a certain amount of qualified abrasive. The qualified abrasive in the receiving chute 15 is then removed by workers or mechanical equipment at regular intervals or as needed for transfer and reuse.

[0043] In another embodiment, the receiving chute 15 is connected to a downstream mechanism (which may be a storage device, a transfer device, or a working device that requires the use of abrasives). Qualified abrasives enter the receiving chute 15 during the vibration feeding process and can easily enter the downstream mechanism along the receiving chute 15.

[0044] Optionally, the diameter of the receiving chute 15 is smaller the further away from the screen plate 12, so as to collect qualified abrasive and guide the qualified abrasive towards the downstream mechanism.

[0045] For details, please refer to Figure 1 In the illustrated embodiment, the diameter of the receiving chute 15 gradually decreases from left to right. The end of the receiving chute 15 connected to the qualified material outlet has a larger diameter so that the abrasive material vibrating down from various positions on the sieve plate 12 can enter the receiving chute 15. The further away from the qualified material outlet, the smaller the diameter of the receiving chute 15 becomes. This gradual reduction in diameter guides the qualified abrasive material to leave the receiving chute 15 from a preset position. When the receiving chute 15 directly connects to the downstream mechanism, the preset position can be the feed end of the downstream mechanism. Reducing the outlet diameter helps the qualified abrasive material to accurately enter the feed end of the downstream mechanism.

[0046] Optionally, the receiving chute 15 is inclined downward in a direction away from the screen plate 12 so that qualified abrasive entering the receiving chute 15 can actively slide to the downstream mechanism.

[0047] Specifically, the receiving chute 15 is inclined downward toward the downstream mechanism. In this way, after qualified abrasive enters the receiving chute 15, it can actively and quickly slide toward the downstream mechanism under its own weight, thereby accelerating the discharge speed of the abrasive regeneration processing mechanism 10 and preventing abrasive residue in the receiving chute 15, or even blocking the outlet of the receiving chute 15 and affecting the downstream material use.

[0048] Optionally, the abrasive regeneration processing mechanism 10 also includes a spraying mechanism for spraying water onto the feed trough 11. The spraying water can both wash the abrasive and prevent the abrasive from accumulating in the feed trough 11.

[0049] The spraying mechanism can be a regular nozzle or a water pipe. The water outlet is located directly above the material trough 11 and can spray water droplets or water mist onto the material trough 11 from top to bottom. By utilizing the flow of liquid and the vibration of the material trough 11, the abrasive is regenerated and washed, thereby optimizing the regeneration effect of the abrasive and cleaning the screen plate 12 to prevent the screen plate 12 from being blocked.

[0050] The spraying mechanism can also be a high-pressure water gun, which can spray a high-pressure water jet into the material tank 11; increasing water pressure and scouring force can also promote the rolling and rotation of abrasives, further improving regeneration efficiency.

[0051] This application also provides a grinding device, including the above-mentioned abrasive regeneration processing mechanism 10, and a grinding mechanism 20. The grinding mechanism 20 is capable of loading abrasive and grinding workpieces with the abrasive. The regeneration processing mechanism 10 is located downstream of the grinding mechanism 20 and is used to receive the old abrasive used by the grinding mechanism 20 and to regenerate the old abrasive.

[0052] Specifically, the grinding mechanism 20 includes: a barrel 21 for loading abrasive and providing space for grinding the workpiece, with a discharge port on one side of the barrel 21; a cover plate 22, which is flip-mounted on the side of the discharge port to block the discharge port; a cover-flipping drive 23 (which can be any drive structure such as a cylinder or electric cylinder that can drive the cover plate 22 to flip relative to the discharge port) for driving the cover plate 22 to move closer to or away from the discharge port; and a grinding vibrator 24 for driving the barrel 21 to reciprocate. When grinding the workpiece, the discharge port is closed, and under the drive of the grinding vibrator 24, the barrel 21 vibrates, and the abrasive in the barrel 21 acts on the workpiece under the vibration to achieve grinding of the workpiece.

[0053] For details, please refer to Figure 2 In the illustrated embodiment, the feed trough 11 is directly opposite the discharge port and located below it. When the grinding mechanism 20 changes the abrasive, the flip-top drive 23 drives the cover plate 22 to rise and move away from the discharge port, opening the discharge port. The old abrasive is continuously discharged through the discharge port under vibration. The old abrasive leaving the discharge port can fall into the feed trough 11 under its own weight and is finally regenerated by the abrasive regeneration processing mechanism 10. After the old abrasive is discharged, the flip-top drive 23 drives the cover plate 22 to fall down and move closer to the discharge port, closing the discharge port. The feed cylinder 21 can then receive new abrasive and prepare for the next stage of grinding.

[0054] 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. Therefore, the protection scope of this patent application should be determined by the appended claims.
