[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 This utility model provides a technical solution: an abrasive replenishment device for the initial grinding of bearing steel balls, including a storage tank 1, a sealing cover plate 2 installed on the top of the storage tank 1, a replenishment pipe 3 installed in the middle of the upper part of the sealing cover plate 2, a solenoid valve 4 installed on the surface of the replenishment pipe 3, a controller 5 installed on the outer wall surface of the storage tank 1, a liquid level sensor 6 installed inside the storage tank 1, a fixing plate 7 connected to the bottom of the outer side of the storage tank 1, a discharge control mechanism 8 provided on the bottom side of the fixing plate 7, and an installation mechanism 9 provided at the bottom of the discharge control mechanism 8; The discharge control mechanism 8 includes a motor housing 801, which is mounted on one side of the fixed plate 7. A motor 802 is installed inside the motor housing 801. The output end of the motor 802 is connected to a drive wheel 803. A driven wheel 804 is meshed with one side of the drive wheel 803. A rotating shaft 805 is connected to the bottom of the driven wheel 804. A connecting bearing 806 is connected to the bottom of the rotating shaft 805. A rotating disk 807 is connected to the bottom of the connecting bearing 806. A discharge hole 808 is opened on the surface of the rotating disk 807. A mounting mechanism 9 is installed on the rotating disk 807. Through the arrangement of the discharge control mechanism 8, when abrasive needs to be replenished, the controller 5 receives a signal from the liquid level sensor 6 or an external command and starts the motor 802 inside the motor housing 801. The output end of the motor 802 drives the drive wheel 803 to rotate. The drive wheel 803 meshes with the driven wheel 804, causing the driven wheel 804 to drive the rotating shaft 805 to rotate. The rotating shaft 805 drives the rotating disk 807 to rotate synchronously through the connecting bearing 806. The connecting bearing 806 ensures that the rotating shaft 805 and the rotating disk 807 rotate smoothly and stably. Since the surface of the rotating disk 807 is provided with four sets of discharge holes 808 with different diameters, during the rotation, the discharge holes 808 with different diameters will be aligned with the discharge port at the bottom of the storage box 1 in sequence. The controller 5 can control the rotation angle of the motor 802 according to the particle size and amount of abrasive required for the initial grinding, so that the corresponding discharge holes 808 are precisely aligned with the discharge port. Under the action of gravity, the abrasive falls through the discharge holes 808 to the mounting mechanism 9, and is then transported to the grinding area by the mounting mechanism 9. By adjusting the forward and reverse rotation and speed of the motor 802, the rotation speed and start and stop of the rotating disk 807 can be controlled, thereby adjusting the discharge speed and flow rate of the abrasive. The four sets of discharge holes 808 with different diameters can adapt to the replenishment needs of abrasives with different particle sizes, realizing precise and controllable replenishment of abrasives.

[0017] Furthermore, two identical sets of liquid level sensors 6 are installed inside the storage tank 1, and are symmetrically distributed on both sides of the inner wall of the storage tank 1 with respect to the central axis of the storage tank 1. Through the installation of liquid level sensors 6, the two symmetrically distributed liquid level sensors 6 can more accurately monitor the remaining amount of abrasive in the storage tank 1, reduce misjudgments caused by the failure of a single sensor or monitoring blind spots, and ensure that the controller 5 can receive the signal of insufficient abrasive in a timely manner, thereby starting the replenishment process and ensuring the continuity of abrasive supply.

[0018] Furthermore, the diameter of the driving wheel 803 is smaller than that of the driven wheel 804, and the number of teeth of the driving wheel 803 is less than that of the driven wheel 804. Through the arrangement of the driving wheel 803 and the driven wheel 804, the driving wheel 803 has a small diameter and fewer teeth. When it meshes with the driven wheel 804, it can achieve speed reduction transmission, reduce the rotation speed of the rotating shaft 805 and the rotating disk 807, make the rotation of the rotating disk 807 more stable, and facilitate the controller 5 to accurately control the alignment time of the discharge holes 808 of different diameters with the discharge port, thereby improving the accuracy of abrasive discharge.

[0019] Furthermore, multiple sets of discharge holes 808 are formed on the surface of the rotating disk 807, and the diameter of each set of discharge holes 808 is different. The position of each set of discharge holes 808 corresponds to the position of the discharge port formed at the bottom of the storage box 1. By setting up the discharge holes 808, multiple sets of discharge holes 808 with different diameters can adapt to the replenishment needs of abrasives with different particle sizes. The fact that each set of discharge holes 808 corresponds to the position of the discharge port at the bottom of the storage box 1 ensures that the abrasive can fall accurately through the discharge holes. At the same time, the discharge amount and speed of the abrasive can be controlled by selecting different diameter discharge holes 808, which enhances the adaptability of the device to different grinding scenarios.

[0020] Furthermore, the installation mechanism 9 includes a flexible hose 901, which is installed at the bottom of the rotating disk 807, corresponding to the position of the discharge port 808. The top two sides of the flexible hose 901 are connected to locking blocks 902. A locking groove 903 is formed at the bottom of the rotating disk 807. A positioning hole 904 is formed inside the locking block 902. A spring 905 is connected to the inner end of the positioning hole 904. The other end of the spring 905 is connected to a limiting plate 906. A fixing block 907 is connected to the outer side of the limiting plate 906. A fixing hole 908 is formed on the inner side of the locking groove 903. The bottom of the flexible hose 901... The unit is connected to a spray head 909. Through the installation mechanism 9, when installing the hose 901, the locking blocks 902 on both sides of the top of the hose 901 are aligned with the slots 903 at the bottom of the rotating disk 807 and pushed in. As the locking blocks 902 enter the slots 903, the fixing block 907 is squeezed by the inner wall of the slots 903, pushing the limiting plate 906 to compress the spring 905 and retract inwards. When the locking blocks 902 are fully embedded in the slots 903, the fixing block 907 is ejected under the elastic force of the spring 905, passes through the positioning hole 904, and engages with the fixing hole 90 on the inner side of the slot 903. 8. Achieve rapid fixation of the hose 901 to the rotating disk 807, and ensure precise alignment of the hose 901 with the discharge port 808. Because the hose 901 has the characteristic of being able to extend and shorten, its length can be flexibly adjusted according to the distance between the grinder and the installation mechanism 9 during abrasive conveying: when the grinder is far away, extend the hose 901 so that the spray head 909 at its bottom is precisely aligned with the initial grinding area; when the grinder is close, shorten the hose 901 to prevent the hose from sagging and causing bending or blockage of the abrasive conveying path. After the abrasive falls from the discharge port 808, it passes through the extendable... The hose 901 stably delivers the abrasive to the spray head 909, which then sprays it evenly onto the bearing steel ball initial grinding area. If the hose 901 needs to be replaced or maintained, a large pulling force is used to pull down the top of the hose 901, causing the fixing block 907 to squeeze the spring 905 out of the fixing hole 908 and retract into the positioning hole 904. The locking block 902 can then be pulled out of the locking groove 903, completing the disassembly. This design ensures the stability of the hose installation and the sealing of the abrasive delivery, while also improving the adaptability of the device to different working conditions through the telescopic function. It is convenient to operate and highly practical.

[0021] Furthermore, the hose 901 is installed at the bottom of the rotating disk 807 via the locking block 902 and the locking groove 903. The outer wall size of the locking block 902 matches the inner wall size of the locking groove 903. Through the setting of the locking block 902 and the locking groove 903, the structure of the outer and inner wall sizes of the two can achieve precise positioning of the hose 901 and the rotating disk 807, avoid the hose 901 from shifting or shaking after installation, ensure that the hose 901 and the discharge hole 808 always remain aligned, and at the same time provide a stable installation base for the hose to prevent material leakage caused by the hose shaking during the abrasive conveying process.

[0022] Furthermore, the limiting plate 906, together with the fixing block 907, forms a telescopic structure. The position of the fixing block 907 corresponds to the position of the fixing hole 908, and their dimensions match. Through the arrangement of the spring 905, the limiting plate 906, the fixing block 907, and the fixing hole 908, the telescopic structure allows the fixing block 907 to automatically pop out and lock into the fixing hole 908 when the locking block 902 is inserted into the locking groove 903, thereby achieving rapid fixing of the hose 901. Moreover, the fixing block 907 and the fixing hole 908 match in size and position, which can firmly lock the locking block 902 and prevent the hose from falling off, thus balancing the stability of installation and the convenience of operation.

[0023] Working Principle: After the device is started, two sets of symmetrically distributed liquid level sensors 6 inside the storage tank 1 monitor the abrasive balance in real time and transmit the data to the controller 5. When the abrasive balance is lower than the set value, the controller 5 opens the solenoid valve 4 on the surface of the feeding pipe 3, and the external abrasive enters the storage tank 1 through the feeding pipe 3 until the liquid level sensor 6 detects that the abrasive balance has reached the preset amount. Then, the controller 5 closes the solenoid valve 4, completing the automatic feeding. When the bearing steel balls need to be replenished with abrasive during initial grinding, the controller 5 receives an external command or a signal from the liquid level sensor 6 and starts the motor 802 in the discharge control mechanism 8. The motor 802 drives the drive wheel 803 to rotate. Through meshing transmission with the driven wheel 804, the rotating shaft 805 drives the rotating disk 807 to rotate via the connecting bearing 806. The controller 5 controls the rotation angle of the motor 802 according to the required abrasive particle size and quantity, so that the discharge hole 808 on the surface of the rotating disk 807 with the corresponding diameter is precisely aligned with the discharge port at the bottom of the storage tank 1. The abrasive passes through the discharge hole 808 under the action of gravity. The hose 901 is fixed to the bottom of the rotating disk 807 by the precise cooperation of the locking block 902 and the locking groove 903. The synergistic action of the spring 905, the fixing block 907 and the fixing hole 908 ensures that the hose 901 is installed firmly. After the abrasive enters the hose 901, the length of the hose 901 can be adjusted by stretching or shortening it according to the distance between the grinder and the device to avoid bending and blockage of the conveying path. Finally, it is evenly sprayed to the initial grinding area through the spray head 909. If the hose 901 needs to be replaced, a large pulling force is used to pull down the top of the hose 901, so that the fixing block 907 squeezes the spring 905 out of the fixing hole 908 and retracts into the positioning hole 904. The locking block 902 can then be pulled out to complete the disassembly. The operation is convenient. The entire device realizes automatic abrasive replenishment, precise quantitative delivery and flexible adaptation to different grinding scenarios through the coordinated operation of various mechanisms, providing stable abrasive support for the initial grinding of bearing steel balls. This completes the use process of an abrasive replenishment device for the initial grinding of bearing steel balls.
