[0029] Reference Figure 1-7As shown, an automated bead grinding machine includes a frame 1, a grinding mechanism 2, a feeding mechanism 3, and a control box 4. The grinding mechanism 2 and the feeding mechanism 3 are fixed to the frame 1. The grinding mechanism 2 includes a lifting assembly 21, a lower shaft seat 22, an upper shaft seat 23, a moving grinding disc 24, a fixed grinding disc 25, a grinding motor 26, a liquid injection port 27, and a discharge hopper 28. The lifting assembly 21 is fixed to the frame 1, the lower shaft seat 22 is fixed to the bottom of the lifting assembly 21, and the upper shaft seat 23 is fixedly connected to the slider of the lifting assembly 21. The moving grinding disc 24 is mounted on the lower shaft seat 22, and the fixed grinding disc 25 is fixed to the upper shaft seat 23. The moving grinding disc 24 and the fixed grinding disc 25 are respectively provided with a plurality of corresponding concentric grinding grooves 29. The grinding motor 26 is fixed to the frame 1, and the moving grinding disc 24 and the grinding motor 26 are connected to each other. The fixed grinding disc 25 has a liquid injection port 27 at its center, which communicates with the outside. The moving grinding disc 24 is located inside the discharge hopper 28. The feeding mechanism 3 includes a propulsion component 31, a feeding plate 32, a feeding hopper 33, and a baffle component 34. The propulsion component 31 is mounted on the frame 1 on the side of the moving grinding disc 24. The feeding plate 32 is inclined on the slider of the propulsion component 31, so that the front end of the feeding plate 32 is located above or away from the moving grinding disc 24. The feeding plate 32 has several dividing plates 35 inside, forming dividing grooves 36 that correspond one-to-one with the circular grinding grooves 29. The feeding hopper 33 is located at the upstream end of the feeding plate 32 and connected to the dividing grooves 36. The baffle component 34 is located at the downstream end of the dividing grooves 36. The lifting component 21, the grinding motor 26, the propulsion component 31, and the baffle component 34 are electrically connected to the control box 4.

[0030] The feeding mechanism 3 automatically feeds the grinding mechanism 2 by adding the grinding balls to be processed into the feeding hopper 33. The material is pre-distributed into the distribution trough 36 by the distribution plate 35 on the feeding plate 32. When no feeding is required, the material is blocked by the front-end baffle component 34 and stored in the feeding plate 32. The feeding plate 32 is a trough-shaped mechanism and can be equipped with a top cover to prevent the material from popping out. When feeding is required, the push component 31 is activated to push the feeding plate 32 as a whole into the grinding mechanism 2, so that the front end of the feeding plate 32 is above the moving grinding disc 24. Then the baffle component 34 is activated to add the material into the circular grinding trough 29. After the feeding amount is reached, the baffle component 34 is closed and the push component 31 is reset. Then, the lifting assembly 21 operates, lowering the fixed grinding disc 25 to cover the moving grinding disc 24. The pressing force is set as needed, and the grinding motor 26 is started. The moving grinding disc 24 and the grinding motor 26 are linked by gears, belts, or other means. Coolant is added between the two grinding discs through the injection port 27, and the material is ground between the moving grinding disc 24 and the fixed grinding disc 25. After grinding is complete, sufficient grinding can be determined by water quality, time, or other methods. The lifting assembly 21 is then activated, raising the fixed grinding disc 25. At this point, it can be visually observed whether grinding is complete and whether to continue grinding. Once completed, the grinding motor 26 rapidly rotates to throw out the grinding balls on the moving grinding disc 24, completing the material discharge.

[0031] Furthermore, the lifting assembly 21 includes a lifting frame 211, a mounting plate 212, a slide rail 213, a lifting slider 214, a lead screw 215, a lifting motor 216, and a motor frame 217. The lifting frame 211 is fixed to the frame 1, the mounting plate 212 is vertically fixed to the lifting frame 211, the slide rail 213 is vertically mounted on the mounting plate 212, the lifting slider 214 is connected to the slide rail 213, the lead screw 215 is threadedly connected to the lifting slider 214, and the motor frame 217 is fixed to the mounting plate 21. 2. At the upper or lower end, the lifting motor 216 is fixed on the lifting frame 211, and the lifting motor 216 is linked with the lead screw 215; the pushing assembly 31 is provided with a pushing plate 311, a sliding rod 312, a pushing slider 313 and a pushing cylinder 314. The sliding rod 312 is arranged parallel to both sides of the pushing plate 311. The pushing slider 313 is connected to the sliding rods 312 on both sides. The rear end of the feeding plate 32 is connected to the pushing slider 313. The pushing cylinder 314 is fixed to the rear end of the pushing plate 311 and connected to the pushing slider 313.

[0032] The fixed grinding disc 25 is raised and lowered by the lifting component 21 to achieve precise coordination with the moving grinding disc 24. The screw 215 structure can prevent the problem of falling. The propulsion component 31 can achieve rapid adjustment between two points and a line, improving efficiency.

[0033] Furthermore, the push plate 311 is tilted and fixed to one side of the grinding mechanism 2, and the material distribution groove 36 corresponds one-to-one with the circular grinding groove 29.

[0034] The push plate 311 is tilted so that when the push assembly 31 moves forward, the front end of the feed plate 32 is fed onto the moving grinding disc 24, and then the moving grinding disc 24 is withdrawn after resetting. Since the discharge hopper 28 is higher than the moving grinding disc 24, the feed plate 32 also needs to be higher than the discharge hopper 28.

[0035] Furthermore, one end of the push plate 311 is rotatably connected to the frame 1, and the other end of the push plate 311 is provided with a lifting cylinder 315. The lifting cylinder 315 is rotatably connected to the frame 1, and the telescopic rod of the lifting cylinder 315 is connected to the push plate 311.

[0036] By cooperating with the push assembly 31 and the lifting cylinder 315, the push assembly 31 can be used to push the material horizontally, and then the lifting cylinder 315 can be used to raise or lower one end of the push plate 311, so that the front end of the feed plate 32 is closer to the moving grinding disc 24, thus avoiding the grinding balls from bouncing up due to a large height difference.

[0037] Since the discharge hopper 28 is higher than the moving grinding disc 24, and the feed plate 32 needs to be higher than the discharge hopper 28, it is necessary to adopt an inclined or lifting setting.

[0038] Furthermore, the telescopic rod of the lifting cylinder 315 is connected to the push plate 311 by a rotating shaft, or the push plate 311 is provided with a movable hole 316, and the front end of the telescopic rod is provided with a push rod 317, which is inserted into the movable hole 316.

[0039] To ensure that the two ends can move relative to each other when the lifting cylinder 315 is activated, thus preventing deformation of the telescopic rod.

[0040] Furthermore, the material blocking assembly 34 is provided with a material blocking cylinder 341 and a material blocking plate 342. The material blocking cylinder 341 is located on both sides of the downstream end of the feed plate 32. The material blocking plate 342 is located above the feed plate 32 and is connected to the telescopic rod of the material blocking cylinder 341. The front end of the material blocking plate 342 is provided with a corresponding material blocking finger plate 343 corresponding to the material distribution groove 36. The material blocking finger plate 343 is inserted into the material distribution groove 36.

[0041] The material blocking assembly 34 raises the material blocking plate 342 through the material blocking cylinder 341, so that the material blocking finger plate 343 disengages from the material distribution trough 36, and the material can slide down from the material distribution trough 36.

[0042] Furthermore, an extension plate 344 is provided between the baffle plate 342 and the baffle finger plate 343, and the length of the extension plate 344 changes sequentially from the outer ring to the inner ring of the circular grinding groove 29.

[0043] The length can be gradually shortened. In this case, the feeding mechanism 3 is controlled to pre-store the beads to be added upstream of the baffle assembly 34, and the number of beads in each distribution groove 36 matches the number of grinding grooves 29. When the baffle plate 342 is opened, the corresponding number of beads in the distribution groove 36 are added to each grinding groove 29. Alternatively, the length can be gradually increased. In this case, the feeding mechanism 3 is controlled to pre-store the beads to be added upstream of the baffle assembly 34, and the baffle plate 342 is opened. The beads are blocked at the discharge hole 345, so that the number of beads downstream of the baffle plate 342 is inconsistent, resulting in a larger number of beads in the outer ring. Ultimately, both methods can achieve the maximum number of beads stored in the outermost distribution groove 36, which matches the outermost grinding groove 29 to the maximum extent, and place as many beads as possible on the grinding groove 29.

[0044] The length of the extension plate 344 needs to be set according to the circumference of each circular grinding groove 29 on the moving grinding disc 24, and the length of the feed plate 32 needs to be matched to avoid overflow due to too many balls and low processing efficiency due to too few balls.

[0045] Furthermore, the downstream end of the baffle plate 342 is provided with a discharge hole 345, and the end of the dividing plate 35 is provided with a blocking plate 346.

[0046] The baffle plate 346 blocks the material from falling from the feed hole 345 onto the moving grinding disc 24, reducing or eliminating its forward rolling force and preventing it from rolling out of the grinding groove 29.

[0047] Furthermore, a feeding assembly 37 is provided between the feeding hopper 33 and the feeding plate 32. The feeding assembly 37 is provided with a feeding cylinder 371, a chute 372 and a feeding plate 373. The chute 372 is provided on both sides of the feeding plate 32, and the feeding plate 373 is provided in the chute 372 on both sides. The feeding plate 373 is provided with a feeding slot hole 374 in the middle that spans the material distribution slot 36. The feeding cylinder 371 is fixed on the feeding plate 32, and the telescopic rod of the feeding cylinder 371 is connected to the feeding plate 373.

[0048] The material moves back and forth through the feed plate 373 of the feed assembly 37, preventing the material from accumulating and being squeezed at the outlet of the feed hopper 33, and allowing it to be neatly arranged in the feed slot 374 and accurately distributed into the distribution slot 36.

[0049] Furthermore, a material frame 5 is provided between the grinding mechanism 2 and the feeding mechanism 3; a rubber layer is provided on the inner side of the discharge hopper 28.

[0050] The material frame 5 is used to collect materials that fall into the distribution trough 36. The rubber layer can prevent the grinding balls from colliding with the discharge hopper 28 and causing damage, thus playing a cushioning role.

[0051] During processing, the feeding mechanism 3 is moved away from the grinding mechanism 2, the moving grinding disc 24 and the fixed grinding disc 25 are separated, the material blocking component 34 is closed, and the material is added into the feeding hopper 33; when the equipment is turned on, the feeding component 37 is started, the feeding cylinder 371 drives the feeding plate 373 to move back and forth, and the material falls from the feeding slot hole 374 into the distribution slot 36. After a single feeding is completed in the distribution slot 36, no more feeding can be carried out. The feeding slot hole 374 is misaligned with the feeding port of the feeding hopper 33, and the material can no longer enter the distribution slot 36. When the push assembly 31 is activated, the front end of the feed plate 32 is moved above the moving grinding disc 24, and the distribution groove 36 corresponds one-to-one with the circular grinding groove 29. The lifting cylinder 315 is activated, and the front end of the feed plate 32 is further lowered to a suitable height to avoid problems such as material bouncing due to excessive height. Then, the baffle assembly 34 is opened, and all the material in the feed plate 32 is added into the circular grinding groove 29 of the moving grinding disc 24. Due to the inclined setting of the feed plate 32, if the rolling speed is too fast, it will roll out of the circular grinding groove 29, especially the material at the upper end of the feed plate 32. During the feeding process, the moving grinding disc 24 rotates synchronously, so that the material is spread evenly in the circular grinding groove 29, and all the beads in the distribution groove 36 are added into the circular grinding groove 29. After the feeding is completed, the forward and reverse rotation can be alternated to make the material evenly distributed, which is beneficial to subsequent grinding. After feeding is completed, the lifting mechanism resets, the front end of the feed plate 32 is raised, the push component 31 is retracted, the lifting component 21 is activated, the fixed grinding disc 25 descends and covers the moving grinding disc 24, the coolant is added from the injection port 27 between the two grinding discs, and the grinding motor 26 is turned on; after grinding is completed, the grinding motor 26 is turned off, the coolant is turned off, the fixed grinding disc 25 is raised, and the grinding ball is instantly accelerated by the grinding motor 26 and thrown from the moving grinding disc 24 into the discharge hopper 28.

[0052] In another processing method, the feeding mechanism 3 is away from the grinding mechanism 2, the moving grinding disc 24 and the fixed grinding disc 25 are separated, the material blocking component 34 is closed, and the material is added into the feeding hopper 33; the equipment is turned on, the feeding component 37 is started, the feeding cylinder 371 drives the feeding plate 373 to move back and forth, and the material falls from the feeding slot hole 374 into the distribution slot 36. After a single feeding is completed in the distribution slot 36, the feeding slot hole 374 and the feeding port of the feeding hopper 33 can be misaligned or not misaligned. When the propulsion component 31 is activated, the front end of the feed plate 32 is moved above the moving grinding disc 24, and the material distribution groove 36 corresponds one-to-one with the circular grinding groove 29. The lifting cylinder 315 is activated, further lowering the front end of the feed plate 32 to a suitable height—just enough to pass through one bead, slightly higher than one bead, or higher than one bead but less than two beads—to prevent material from bouncing due to excessive height. Then, the material blocking component 34 is opened, and all the material in the feed plate 32 is added to the circular grinding groove of the moving grinding disc 24. Inside the grinding groove 29, due to the inclined setting of the feed plate 32, if the rolling speed is too fast, the material will roll out of the grinding groove 29, especially the material at the upper end of the feed plate 32. After the baffle plate 342 is opened, the moving grinding disc 24 does not rotate. When all the beads at the front end of the distribution groove 36 reach the position of the discharge hole 345, the grinding disc 24 is started again, so that the material is spread evenly in the grinding groove 29. When the amount of beads reaches the baffle plate 342, it is closed to prevent the beads from entering. After the feeding is completed, the forward and reverse rotation can be alternated to make the material evenly distributed, which is beneficial to subsequent grinding. After feeding is completed, the lifting mechanism resets, the front end of the feed plate 32 is raised, the push component 31 is retracted, the lifting component 21 is activated, the fixed grinding disc 25 descends and covers the moving grinding disc 24, the coolant is added from the injection port 27 between the two grinding discs, and the grinding motor 26 is turned on; after grinding is completed, the grinding motor 26 is turned off, the coolant is turned off, the fixed grinding disc 25 is raised, and the grinding ball is instantly accelerated by the grinding motor 26 and thrown from the moving grinding disc 24 into the discharge hopper 28.

[0053] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
