When preparing these powders, large pieces of raw materials need to be broken into small pieces by a crusher, and then the small pieces of raw materials are ground into powder by a grinding device.

[0003] Chinese patent CN217962824U discloses a bidirectional grinding device for the preparation of water-based coatings. The driven gear rotates and drives another driven gear to rotate and engage with the direction-changing gear. The direction-changing gear rotates and engages with the gear ring to drive the grinding pot to rotate. Due to the setting of the direction-changing gear, the grinding stone and the grinding pot rotate in opposite directions, so that the raw material is subjected to extrusion forces in two directions during grinding, thereby accelerating the grinding efficiency.

[0004] The above-mentioned device crushes the raw materials by means of the provided grinding stone and grinding kettle, and cleans the powder on the surface of the grinding stone and grinding kettle by means of a cleaning brush. However, in actual use, since the grinding stone and grinding kettle are relatively close to each other, it is difficult to clean the grinding position on the grinding stone and grinding kettle by means of the above-mentioned structure. In summary, there is still room for improvement in the above-mentioned device.

DETAILED DESCRIPTION

[0033] like Figures 1-10 As shown, a water-based paint raw material grinder includes a grinding block 5 for grinding and a grinding table 6 mounted on the outside of the grinding block 5, and a grinding groove 14 for accommodating raw materials is formed between the grinding block 5 and the grinding table 6. Of course, the space of the grinding groove 14 gradually decreases from top to bottom, which is conducive to gradually crushing the raw materials.

[0034] Further, combined with Figure 1-Figure 5 As shown, there are two grinding tables 6 in this scheme and the grinding tables 6 are semi-cylindrical as a whole. When the two grinding tables 6 are fitted together, they can form a complete cylindrical structure and can be mounted on the outside of the grinding block 5, so that the grinding block 5 is located at the center of the two grinding tables 6. In actual use, the raw material of the water-based paint is put onto the top of the grinding block 5 (the top of the grinding block 5 is a conical surface). When the raw material falls into the grinding groove 14, the raw material can be ground through the cooperation between the grinding block 5 and the grinding table 6.

[0035] Combine Figure 3-Figure 8 As shown, a cleaning assembly is provided between the two grinding tables 6, and the cleaning assembly is detachably connected to the pushing assembly between the two grinding tables 6. During actual use, when the two grinding tables 6 move away from each other, the pushing assembly can drive the cleaning assembly to move toward the direction close to the grinding block 5, thereby facilitating the cleaning of residual raw materials on the surface of the grinding block 5.

[0036] Combine Figure 6-Figure 8As shown, the cleaning assembly includes a base plate 10 and bristles 1002 fixed on both sides of the base plate 10. The bristles 1002 can be made of plastic or nylon. A slot 1001 is opened on the outer side of the base plate 10. The cross section of the slot 1001 is T-shaped.

[0037] The pushing assembly includes a slide bar 2 disposed on the outside of the base plate 10. The end of the slide bar 2 close to the base plate 10 is integrally formed with an insert block 202 that matches the slot 1001. Figure 6 As shown, notches for the card block 16 to slide are provided on both sides of the insert block 202, and a spring is fixedly provided between the inner end surface of the notch and the card block 16. Furthermore, a first inclined surface 1601 is provided on the top of the card block 16 and on the side close to the substrate 10. When the slide bar 2 approaches the substrate 10, the insert block 202 can be inserted into the slot 1001. The first inclined surface 1601 allows the card block 16 to enter the slot 1001. When the card block 16 pops out and engages with the slot 1001, the slide bar 2 and the substrate 10 are engaged.

[0038] Further, combined with Figure 1-Figure 7 As shown, bosses 201 are fixedly provided on both sides of the slide bar 2, so that the slide bar 2 and the bosses 201 are in the shape of a "cross" as a whole. Limiting grooves 9 are provided on both bosses 201, and the two limiting grooves 9 are arranged in an "eight" shape. A bracket is fixedly installed on the outer side of the grinding table 6, and a limiting column 8 is fixedly provided on one end of the bracket close to the support table 102. The limiting column 8 is inserted into the limiting groove 9 and can slide relative to the limiting groove 9;

[0039] Combine Figure 1-Figure 2 As shown, a cylinder 1 is sleeved on the outer side of the grinding table 6, and the above-mentioned slide rod 2 passes through the cylinder 1 and slides with the cylinder 1, so that the slide rod 2 can move relative to the cylinder 1 along its diameter direction. Of course, in actual use, the slide rod 2 can also be elastically connected to the cylinder 1 through a first spring.

[0040] Through this structure, when the two grinding tables 6 are separated, the cooperation between the limiting column 8 and the limiting groove 9 can drive the slide rod 2 to gradually approach the grinding block 5, so that the bristles 1002 on the base plate 10 can contact the outer surface of the grinding block 5. When the grinding block 5 rotates relative to the grinding table 6, the bristles 1002 are used to clean the raw materials remaining on the outer surface of the grinding block 5. Afterwards, when the two grinding tables 6 approach each other, the pressure of the limiting column 8 on the side wall of the limiting groove 9 can drive the slide rod 2 and the base plate 10 at one end of the slide rod 2 to gradually move away from the grinding block 5.

[0041] Combine Figure 5 、 Figure 8 As shown, the bottom end of the base plate 10 is fixed with an inserting plate 11, which is in a horizontal state. Figure 5As shown, the outer peripheral wall of the grinding table 6 is provided with an avoidance groove 601 for accommodating structures such as the base plate 10 and the inserting plate 11. When the two grinding tables 6 are attached to each other, the base plate 10 and the inserting plate 11 can be completely accommodated in the avoidance groove 601, thereby preventing the base plate 10 or the inserting plate 11 from interfering with the grinding table 6.

[0042] The bottom end face of the grinding block 5 is provided with a rotating shaft 26, Figure 5-Figure 7 As shown, a blind hole 501 is provided at the bottom end surface of the grinding block 5 to cooperate with the rotating shaft 26. The rotating shaft 26 can be rotatably matched with the grinding block 5 through a bearing, so that the rotating shaft 26 can be connected to the grinding block 5 through a clamping assembly, and the grinding table 6 can synchronously drive the rotating shaft 26 to rotate through the clamping assembly;

[0043] Furthermore, the outer side of the rotating shaft 26 is fixedly sleeved with an annular plate 15, and the outer peripheral wall of the annular plate 15 is provided with a strip groove 1501 that matches the inserting plate 11. Figure 8 As shown;

[0044] A support block 7 is provided at the bottom end of the rotating shaft 26. In actual use, a friction unit can be arranged between the rotating shaft 26 and the support block 7 to increase the interaction force between the rotating shaft 26 and the support block 7;

[0045] In the initial state, the rotating shaft 26 is not connected to the grinding block 5 by the clamping assembly, and the strip groove 1501 on the annular plate 15 is in the same straight line with the insert plate 11. When the base plate 10 is gradually driven close to the grinding block 5 by the slide bar 2, the insert plate 11 can be inserted into the strip groove 1501, and the action force between the rotating shaft 26 and the support block 7 can keep the rotating shaft 26 and the annular plate 15 stable, and thus keep the base plate 10 stable, so that during the rotation of the grinding block 5, the bristles 1002 on the base plate 10 can clean the outer surface of the grinding block 5, and when the rotating shaft 26 is connected to the grinding block 5 by the clamping assembly, the insert plate 11 can be inserted into the strip groove 1501. When the blocks 5 are connected, the grinding block 5 can synchronously drive the substrate 10 to rotate. The projection of the slot 1001 on the horizontal plane is arc-shaped as a whole. The center of the slot 1001 coincides with the axis of the grinding block 5. Through this structure, when the grinding block 5 drives the substrate 10 to rotate through the annular plate 15, the insert block 202 and the clamping block 16 can be moved out of the slot 1001 without interfering with the slot 1001. Through this structure, the substrate 10 can cooperate with the grinding block 5 and rotate synchronously with the grinding block 5. During this process, the inner wall of the grinding table 6 can be cleaned by the bristles 1002 on the outer side of the substrate 10.

[0046] Combine Figure 11As shown, the clamping assembly includes a cross bar 22 provided at the rotating shaft 26 and elastically connected to the rotating shaft 26, and a limiting hole 5011 is opened on the inner wall of the blind hole 501 to cooperate with the cross bar 22. The number of the limiting holes 5011 is set to be multiple and distributed in a ring array;

[0047] Combine Figure 5-Figure 11 As shown, a connecting rod 13 is provided at the axis of the rotating shaft 26, and the connecting rod 13 passes through the rotating shaft 26 and can slide up and down relative to the rotating shaft 26. Specifically, a through hole for installing the connecting rod 13 is opened at the axis of the rotating shaft 26. Figure 11 As shown, an annular groove is provided on the inner wall of the through hole and located at the cross bar 22, and a pressure ring 25 is fixedly sleeved on the connecting rod 13. The pressure ring 25 is located in the annular groove, and the upper and lower end surfaces of the pressure ring 25 and the edges are both set as tapered surfaces 2501;

[0048] Furthermore, a transverse groove for mounting the cross bar 22 is provided on the rotating shaft 26. Specifically, the transverse groove is communicated with the annular groove. A fixing block 23 is fixedly provided in the transverse groove, and the cross bar 22 passes through the fixing block 23 and slides with it. In addition, a stopper 24 is fixedly sleeved outside the cross bar 22, and a limit spring is provided between the stopper 24 and the fixing block 23. Of course, the limit spring can be sleeved on the outside of the cross bar 22. Through this structure, when the connecting rod 13 moves downward, the conical surface 2501 on the pressure ring 25 can squeeze the cross bar 22, so that the cross bar 22 overcomes the pressure of the limit spring and moves toward the direction of the limit hole 5011. When one end of the cross bar 22 is inserted into the limit hole 5011, the rotating shaft 26 is connected to the grinding table 6.

[0049] Combine Figure 10As shown, in order to drive the connecting rod 13 to move, the present invention fixes an electromagnet 27 at the center of the support block 7, and the bottom end of the connecting rod 13 is integrally formed with a flange portion 1301, and the flange portion 1301 is made of iron. Specifically, a circular hole is provided on the bottom end face of the rotating shaft 26, and the flange portion 1301 slides in the circular hole, and a tension spring is fixedly provided between the top wall of the circular hole and the flange portion 1301. In the initial state, the electromagnet 27 is not energized, and the pressure ring 25 is staggered with the cross bar 22. In this state, the rotating shaft 26 is not connected to the grinding block 5, so that the bristles 1002 on the base plate 10 can clean the outer surface of the grinding block 5. However, when the staff starts the electromagnet 27 to energize it, the electromagnet 27 is used to press the flange portion. The suction force of 1301 can drive the connecting rod 13 to move downward, so that the pressure ring 25 squeezes the cross bar 22, so that one end of the cross bar 22 can be inserted into the limiting hole 5011, so that the grinding block 5 can synchronously drive the substrate 10 to rotate, and then clean the inner wall of the grinding table 6 through the bristles 1002 on the outer surface of the substrate 10. Of course, when the two grinding tables 6 are away from each other to the extreme position, the substrate 10 can be pushed to the inside of the grinding table 6, so as to avoid the interference of the substrate 10 with the grinding table 6 when the grinding block 5 rotates. During use, when the sliding rod 2 pushes the substrate 10 to be located inside the grinding table 6, the two grinding tables 6 can be driven close to each other until they are fitted together, so that the substrate 10 is limited between the grinding block 5 and the grinding table 6, which is conducive to the stable cleaning of the inner wall of the grinding table 6.

[0050] Although the above structure can clean the grinding block 5 and the grinding table 6, when the two grinding tables 6 are attached to each other, the space between the grinding table 6 and the grinding block 5 (grinding groove 14) is relatively narrow. Therefore, to a certain extent, the cleaning effect of the bristles 1002 is affected. If the two grinding tables 6 are kept separated, when the grinding block 5 rotates at a high speed, the substrate 10 tends to move away from the grinding block 5 due to the centrifugal force. Therefore, when the substrate 10 moves to the gap between the two grinding tables 6, the substrate 10 will be thrown out, thereby interfering with the grinding tables 6.

[0051] Based on this problem, the present invention provides a lifting rod 12 below the annular plate 15. Specifically, a protrusion 20 is fixedly provided on the inner wall of the lifting rod 12, and a vertical rod is fixedly installed on the bottom surface of the annular plate 15. The vertical rod passes through the protrusion 20 and slides with it. A supporting spring is provided between the annular plate 15 and the protrusion 20. The supporting spring can be sleeved on the outside of the vertical rod. Through this structure, the lifting rod 12 and the annular plate 15 are elastically connected. Figure 9 As shown, the top of the lifting rod 12 is elastically connected to a clip 28, which passes through the annular plate 15 and extends into the strip groove 1501, and both sides of the top of the clip 28 are set as second inclined surfaces 19. Specifically, the lifting rod 12 is provided with a receiving groove that slides with the clip 28. Figure 9As can be seen, the cross-sections of the clip 28 and the receiving groove can be "cross" shaped, and a second spring is fixedly provided between the bottom surface of the receiving groove and the clip 28. Figure 5-Figure 6 As shown, a plurality of slots 1101 are provided on the bottom surface of the inserting plate 11. As the inserting plate 11 is inserted into the strip-shaped slot 1501, the inserting plate 11 can press the second inclined surface 19, thereby causing the clamping strip 28 to move downward. However, when the clamping strip 28 is aligned with the slot 1101, the substrate 10 will not be thrown out due to the cooperation between the clamping strip 28 and the slot 1101.

[0052] Furthermore, a collar 701 is sleeved on the outer side of the support block 7, a short rod is fixedly provided between the inner wall of the collar 701 and the support block 7, and a long rod is fixedly provided between the collar 701 and the inner wall of the cylinder 1. Figures 8-10 As shown, a top rod 1201 is fixedly provided at the bottom end of the lifting rod 12, and a layering strip 17 is fixedly provided on the top surface of the collar 701. Both ends of the layering strip 17 are provided with inclined extrusion surfaces 1701. There are two layering strips 17, and the two layering strips 17 are respectively located at the joints of the two grinding tables 6.

[0053] In the initial state, the push rod 1201 is located above the pressure strip 17. At this time, the lifting rod 12 can press the card strip 28. Therefore, when the two grinding tables 6 are separated from each other and the inserting plate 11 is inserted into the strip groove 1501, the cooperation between the card strip 28 and the card groove 1101 can keep the inserting plate 11 and the annular plate 15 stable. When the rotating shaft 26 is engaged with the grinding table 6, the grinding table 6 can rotate and synchronously drive the base plate 10 to rotate, thereby cleaning the inner wall of the grinding table 6. Specifically, when the substrate 10 moves to the inner side of the grinding table 6 and overlaps with the grinding table 6, the push rod 1201 can be moved down from the pressure strip 17, so that the lifting rod 12 bounces downward and drives the card strip 28 to move downward synchronously, so that the card strip 28 is separated from the card slot 1101. At this time, the grinding block 5 can throw out the substrate 10 when it rotates, so that the substrate 10 can be close to the grinding table 6, and then the inner wall of the grinding table 6 is cleaned by the bristles 1002 on the outside of the substrate 10. When the push rod 1201 When the two grinding tables 6 are about to move to the gap between the two grinding tables 6, the push rod 1201 can move above the pressure strip 17 through the extrusion surface 1701, thereby prompting the lifting rod 12 to drive the card strip 28 to move upward, so that one end of the card strip 28 is inserted into the card slot 1101, thereby preventing the substrate 10 from being thrown out by the grinding block 5. Through this structure, the inner wall of the grinding table 6 can be cleaned when the two grinding tables 6 are separated. When the cleaning is completed, the substrate 10 is stopped at one end of the slide bar 2 by the grinding block 5, and the two grinding tables 6 are driven to separate to the limit position, so that the inserting block 202 at the end of the slide bar 2 can be inserted into the slot 1001, and then the cooperation between the card block 16 and the slot 1001 makes it possible to pull the substrate 10 back into the avoidance groove 601 when the two grinding tables 6 are fitted. Since the force acting on the substrate 10 by the slide bar 2 is large, the pressure of the card slot 1101 on the card strip 28 is sufficient to prompt the card strip 28 to move downward, which is conducive to pulling the inserting plate 11 out of the strip groove 1501.

[0054] Two telescopic units 3 are fixedly installed on the outside of the cylinder 1. The telescopic units 3 can be cylinders or hydraulic rods. The telescopic ends of the telescopic units 3 pass through the cylinder 1 and are fixedly connected to the grinding table 6. The telescopic ends of the telescopic units 3 can slide relative to the cylinder 1, thereby driving the grinding table 6 to move.

[0055] A connecting shaft (shown in the figure) is fixedly provided on the top of the grinding block 5. The connecting shaft passes through the cylinder 1 and is rotatably connected thereto, and the connecting shaft cannot move up and down relative to the cylinder 1. In actual application, a retaining ring can be fixedly sleeved on the outside of the connecting shaft so that the retaining ring is located on the top surface of the cylinder 1. A motor is installed on the cylinder 1, and the motor output shaft and the connecting shaft are connected by a transmission unit 4. The transmission unit 4 can be a chain or a belt. Of course, the motor and the connecting shaft can also be connected through a gear set to drive the grinding block 5 to rotate.

[0056] A feed pipe 101 is fixedly provided at the top of the cylinder 1 , and passes through the cylinder 1 and is located above the grinding block 5 , so that the raw material introduced through the feed pipe 101 can fall between the grinding block 5 and the grinding table 6 .

[0057] Reference Figure 3 As shown, support platforms 102 are fixedly provided on both sides of the inner wall of the cylinder 1 , and the grinding table 6 slides on the top of the support platforms 102 .

[0058] Combine Figure 7 As shown, in actual use, the inner wall of the base plate 10 can be parallel to the outer surface of the grinding block 5, and the outer wall of the base plate 10 can be parallel to the inner wall of the grinding table 6.

[0059] Combine Figure 8 As shown, in actual use, a support frame can be installed at the long rod, the support frame is located directly below the slide bar 2, and a detection unit 21 is installed on the side of the support frame close to the rotating shaft 26. The detection unit 21 can be an infrared sensor or an ultrasonic sensor, etc. The detection unit 21 is connected to the above-mentioned motor to control the operation of the motor. When the cleaning is completed, the detection unit 21 is started. When the detection unit 21 detects that the lifting rod 12 rotates to the slide bar 2, the detection unit 21 can stop the rotation of the grinding block 5, which is conducive to the docking of the plug 202 at one end of the slide bar 2 with the substrate 10.

[0060] Combine Figure 12 As shown, in order to increase the force between the rotating shaft 26 and the support block 7, a rubber pad can be bonded to the bottom end surface of the rotating shaft 26, or a plurality of positioning holes can be opened at the bottom end surface of the rotating shaft 26, and the top surface of the support block 7 is elastically connected to a pressure block 18 that matches the positioning hole through a third spring. The top of the pressure block 18 can be a spherical surface. When the outer wall of the grinding block 5 is cleaned by the bristles 1002, the rotating shaft 26 can be kept stable through this structure. When the rotating shaft 26 is engaged with the grinding block 5, as the grinding block 5 rotates, the positioning holes and the spherical surface on the pressure block 18 are squeezed, thereby prompting the pressure block 18 to shrink into the support block 7.
