[0023] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0024] Reference Figure 1-4 As shown, a grinding ball polishing device comprises a processing box 1, a barrel 2 rotatably arranged on the inner wall of the top end of the processing box 1, and a hopper 3 connected and fixed to the top end of the processing box 1, the hopper 3 is connected with the barrel 2 correspondingly, the bottom end of the processing box 1 is connected and fixed with a water outlet pipe 5, a filter plate 4 is fixed between the inner walls at the front and rear sides of the processing box 1, the filter plate 4 is located between the water outlet pipe 5 and the barrel 2, an annular filter screen is fixedly embedded at the bottom end of the barrel 2, and the barrel 2 is built with a grinding roller for grinding grinding balls and a driving structure for driving the barrel 2 and the grinding roller to rotate in opposite directions;

[0025] When in use, the grinding balls to be processed are manually put into the barrel 2 through the hopper 3 in advance, so that the grinding balls are located between the grinding roller and the inner wall of the barrel 2 in the barrel 2, and then the barrel 2 and the grinding roller are driven by the driving structure to rotate in the opposite direction, and the cooling liquid is injected into the barrel 2 from the hopper 3 at the same time, so that the grinding balls can be ground in the process of the reverse rotation of the two, and the impurities generated by grinding can enter the filter plate 4 through the annular filter screen under the flushing of the cooling liquid, so that the filter plate 4 filters and separates the cooling liquid and the impurities, and the impurities are retained on the upper surface of the filter plate 4 for subsequent processing, while the cooling liquid falls to the area below the filter plate 4 and is discharged outward from the outlet pipe 5;

[0026] In addition, after searching the existing patent announcement number CN216030125U, a chrome alloy grinding ball surface automatic grinding device was found. From the patent, it can be seen that the processing box 1, the barrel 2, the hopper 3, the filter plate 4 and the water outlet pipe 5 are technical features that are well known in the prior art and are familiar to the public. This scheme only briefly introduces the use principle, wherein an annular filter is fixedly embedded at the bottom end of the barrel 2, and a grinding roller for grinding the grinding balls and a driving structure for driving the barrel 2 and the grinding roller to rotate in opposite directions are built in. The detailed content and specific internal structure can be referred to the above documents, and this scheme will not make too many descriptions.

[0027] Further, refer to Figure 2 and Figure 3 As shown, it is worth noting that one side of the filter plate 4 is against the inner wall of one side of the processing box 1, an impurity collecting component is arranged between the other side of the filter plate 4 and the inner wall of the other side of the processing box 1, and an impurity cleaning component is arranged on the top surface of the filter plate 4;

[0028] The impurity cleaning component includes a screw rod 8 transversely arranged between the filter plate 4 and the barrel 2, a scraper 9 threadedly connected to the rod body of the screw rod 8, and a motor 10 installed on a side wall of the processing box 1. The bottom end of the scraper 9 contacts the top surface of the filter plate 4, and one end of the screw rod 8 rotates to pass through the processing box 1 and is fixedly connected to the output shaft of the motor 10.

[0029] The impurity collecting component includes a collecting frame 6 with a rectangular frame at one end and a filter screen 7 installed in the bottom opening of the collecting frame 6. The collecting frame 6 passes through the processing box 1 on one side away from the filter plate 4 and is symmetrically fixed with two connecting rods 19. A handle 20 is fixed on the connecting rod 19, and both ends of the connecting rod 19 are detachably connected to the outer wall of the processing box 1 by bolts.

[0030] By setting the impurity collecting component and the impurity cleaning component, after the grinding ball has completed grinding, the motor 10 can be manually turned on to rotate the screw 8, and the scraper 9 can slide toward the side of the collecting frame 6 by the threaded structure during the rotation of the screw 8, so that the scraper 9 scrapes the impurities on the surface of the filter plate 4 and pushes the impurities into the collecting frame 6, so that the impurities are intercepted by the filter net 7, so that the impurities are collected in the collecting frame 6. Subsequently, the manual work only needs to loosen the bolts at both ends of the connecting rod 19 and pull the handle 20 to pull the collecting frame 6 out from the inside of the processing box 1, so as to facilitate the processing of impurities in the collecting frame 6.

[0031] However, from a practical point of view, the screw rod 8 is located between the annular filter screen and the filter plate 4, and the impurities generated by grinding are very likely to adhere to the screw rod 8. Over time, the amount of impurities attached to the surface of the screw rod 8 increases, which easily leads to a large friction between the screw rod 8 and the scraper 9, making it difficult for the screw rod 8 to drive the scraper 9 to move;

[0032] For this purpose, refer to Figure 3 and Figure 4 As shown, it is worth noting that a protection component is provided on the rod body of the screw rod 8;

[0033] The protection assembly includes a protection tube 11 sleeved on the rod body of the screw rod 8, the protection tube 11 is located on the side of the scraper 9 away from the motor 10, the side of the scraper 9 is provided with an embedding groove 12 adapted to the protection tube 11, one end of the protection tube 11 is embedded in the inner side of the embedding groove 12, and a circular mounting groove is provided on the other side wall of the processing box 1, and a ring-shaped embedding block 13 is detachably provided in the circular mounting groove, and the other end of the protection tube 11 is fixedly embedded in the inner side of the embedding block 13;

[0034] By setting the protection assembly, when the grinding balls are grinding in the barrel 2, the protection tube 11 in the protection mechanism can effectively cover the shaft of the screw 8, thereby preventing impurities generated by grinding from directly adhering to the screw 8 and affecting the transmission effect of the screw 8 on the scraper 9;

[0035] The protection tube 11 is on the body of the screw rod 8, and the embedded block 13 fixed at one end of the protection tube 11 is embedded in the circular installation groove, and the other end of the protection tube 11 is embedded in the embedded groove 12, so that the embedded block 13 and the embedded groove 12 can effectively assist in supporting the protection tube 11 and ensure the stability of the protection tube 11 on the body of the screw rod 8;

[0036] Subsequently, it is only necessary to pull the insert 13 to withdraw the protective tube 11 from the inside of the processing box 1, which can reduce the resistance of the protective tube 11 to the movement of the scraper 9, so that when the motor 10 is turned on, the scraper 9 can easily slide along the shaft of the screw rod 8, and the protective tube 11 can be disassembled, making it convenient to clean the impurities on the wall of the protective tube 11 outside the processing box 1, thereby increasing the collection rate of impurities.

[0037] Further, refer to Figure 3 As shown, it is worth noting that two handles 14 are symmetrically fixed on the side of the insert 13 facing away from the motor 10;

[0038] The handle 14 is provided to facilitate manual pushing and pulling of the insert 13 and the protection tube 11 as a whole.

[0039] Further, refer to Figure 3 As shown, it is worth noting that the inner walls of the front and rear sides of the processing box 1 are provided with contraction grooves 16, and the contraction grooves 16 are provided with pipe support components;

[0040] The pipe support assembly includes a drag block 15 which is slidably arranged on the side of the protection tube 11 in a semi-ring shape, a push-pull screw rod 18 is transversely arranged in the center of the contraction groove 16, and a guide rod 17 is transversely arranged on one side of the contraction groove 16. One end of the push-pull screw rod 18 is rotatably connected to the drag block 15, and the other end of the push-pull screw rod 18 is threadedly passed through the processing box 1. One end of the guide rod 17 is fixedly connected to the drag block 15, and the other end of the guide rod 17 slides out of the processing box 1.

[0041] By setting the tube support assembly, when the protective tube 11 is inserted into the circular installation groove, the push-pull screws 18 on the two drag blocks 15 are manually pre-twisted respectively, so that the two drag blocks 15 slide into the processing box 1 under the push of the corresponding push-pull screws 18 and form a cylindrical tubular structure. Therefore, in the process of gradually sleeve the screw rod 8, the protective tube 11 can enter the inner side of the cylindrical tubular structure formed by the two drag blocks 15 in advance, and then the cylindrical tubular structure can effectively support the protective tube 11, ensure the stability of the protective tube 11 during the sleeve process, and prevent the protective tube 11 from tilting and contacting the rod body of the screw rod 8 during the insertion process, causing wear to the rod body of the screw rod 8;

[0042] On the contrary, the knob is subsequently turned in the reverse direction to push and pull the screw 18 to shrink the drag block 15 into the inside of the shrinkage groove 16 , so that the shrinkage groove 16 can be used to hide the drag block 15 to prevent the drag block 15 from affecting the sliding of the scraper 9 above the filter plate 4 .

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
