A main shaft 7 is provided at the output end of the driving motor 1. The main shaft 7 extends into the grinding cylinder 4 and is rotatably connected to the grinding cylinder 4. A plurality of grinding members 8 are provided on one side of the main shaft 7 located in the grinding cylinder 4. A filter member 33 is provided on one side of the main shaft 7 located in the grinding member 8. A grinding medium is placed in the grinding cylinder 4.

The driving motor 1 drives the filter member 33 to rotate and filter the ground material through the main shaft 7. A first scraper plate 10 is fixedly connected between the plurality of grinding members 8. The first scraper plate 10 is slidably connected to the inner wall of the grinding cylinder 4. The length is consistent with the length of the grinding area where the grinding piece 8 is located. The first scraper plate 10 is used to scrape off the grinding material attached to the inner wall of the grinding cylinder 4. A fixed rod 13 is fixedly connected to the upper side of the inner wall of the grinding cylinder 4. One side of the fixed rod 13 is rotatably connected to the first removal plate 11. A reset device is provided on one side of the first removal plate 11. The reset device is used to reset the first removal plate 11 to scrape the first scraper plate 10. The first removal plate 11 is used to scrape off the grinding material attached to the first scraper plate 10.

The discharge device includes a discharge trough 21 slidably connected to one side of the discharge port 6. A reciprocating device is provided on one side of the grinding table 9. The reciprocating device is used to move back and forth with the discharge trough 21.

[0032] Specifically, when the grinder wet-grinds pigments and ceramic grinds, the liquid is mixed with the grinding raw materials to form a mixed grind, the mixed grind and grinding media such as zirconia beads are added into the grinding cylinder 4, the driving device of the grinder is started to rotate the main shaft 7 and the grinding member 8, so that the zirconia beads and the mixed grind move relative to each other in the grinding cylinder 4, so that the mixed grind is effectively dispersed and ground to form a viscous liquid grind, and then the ground viscous liquid grind is discharged from the grinding cylinder 4 for collection and use; when the mixed grind is ground into a viscous liquid grind, the mixed grind will adhere to the inner wall of the grinding cylinder 4, resulting in the grinding medium being unable to fully grind the grind adhered to the inner wall, resulting in insufficient grinding of the ground viscous liquid grind, resulting in the problem that the particles of the ground viscous liquid grind are uneven in size and cannot be used.

[0033] In the present embodiment, when wet grinding pigments and ceramic grinding materials, liquid is mixed with grinding raw materials to form mixed grinding materials, grinding media such as zirconium oxide beads and the mixed grinding materials in the feeding bin 2 are fed into the grinding cylinder 4, and the driving motor 1 is started to make the main shaft 7 rotate with the grinding member 8. The grinding member 8 rotates with the zirconium oxide beads to make relative movement with the mixed grinding materials in the grinding cylinder 4, so that the mixed grinding materials are effectively dispersed and ground to form viscous liquid grinding materials, and the grinding member 8 rotates with the first scraper plate 10 to scrape off the viscous liquid grinding materials adhering to the inner wall of the grinding cylinder 4 to prevent the viscous liquid grinding materials in the grinding cylinder 4 from adhering to the inner wall of the grinding cylinder 4 and causing insufficient grinding. A protrusion is provided on the upper side of the first removal plate 11 in the grinding cylinder 4 so that the first removal plate 11 will protrude from the inner wall of the grinding cylinder 4. When the viscous liquid grinding materials adhering to the inner wall of the grinding cylinder 4 are scraped off by the first scraper plate 10, the first scraper plate 10 will resist The protruding part of the first removal plate 11 causes the first removal plate 11 to rotate through the fixed rod 13. When the first removal plate 11 and the first scraper plate 10 are pressed against and slid, the viscous liquid grinding material adhered to the first scraper plate 10 will be scraped off. The resetting device will make the first removal plate 11 close to the scraping surface of the first scraper plate 10, so that the first scraper plate 10 can continue to scrape off the viscous liquid grinding material adhered to the inner wall of the grinding cylinder 4. After the first removal plate 11 scrapes off the viscous liquid grinding material adhered to the first scraper plate 10, the resetting device resets the first removal plate 11 to the grinding cylinder 4, and then the viscous liquid grinding material adhered to the first scraper plate 10 can be scraped off again so that the viscous liquid grinding material can be fully ground. The fully ground viscous liquid grinding material is discharged to the discharge trough 21 through the discharge port 6, and the viscous liquid grinding material on the discharge trough 21 is quickly collected and utilized by the reciprocating device with the discharge trough 21 to reciprocate.

[0035] Specifically, when the first scraper plate 10 is used to scrape off the viscous liquid grinding material adhered to the inner wall of the grinding cylinder 4, the first scraper plate 10 will hit the protruding part of the first removal plate 11, causing the first removal plate 11 to rotate through the fixed rod 13, and causing the torsion spring 14 to deform and generate elastic force. After the first removal plate 11 scrapes off the viscous liquid grinding material adhered to the first scraper plate 10, the torsion spring 14 restores its deformation to cause the first removal plate 11 to rotate back into the grinding cylinder 4, thereby scraping off the viscous liquid grinding material adhered to the first scraper plate 10 again so that the viscous liquid grinding material can be fully ground.

[0037] Specifically, the initial position of the reciprocating plate 12 is at the rightmost end of the first removal plate 11, and the initial position of the first removal plate 11 is in a retracted state in the grinding cylinder 4. When the first removal plate 11 is rotated by the fixing rod 13, the reciprocating plate 12 will slide on the first removal plate 11 and stretch the first spring 15, sliding the reciprocating plate 12 from the rightmost end of the first removal plate 11 to the left side. When the first removal plate 11 returns to the initial state, the reciprocating plate 12 returns to the initial position at the rightmost end of the first removal plate 11 to scrape off the viscous liquid grinding material adhering to the first removal plate 11.

[0038] like Figure 1 As shown, both sides of the grinding table 9 are provided with shock-absorbing feet 3, and the shock-absorbing feet 3 are all-carbon steel fixed feet, and the shock-absorbing feet 3 are used to isolate and absorb vibrations of the grinding machine.

[0039] Specifically, by using the full carbon steel shock-absorbing foot 3 as the fixed foot of the grinding table 9, the vibration between the grinding table 9 and the ground during grinding by the grinder can be reduced, thereby better protecting the grinder, increasing the service life of the grinder, and reducing the noise generated during grinding.

[0040] like Figure 3 As shown, a protective layer 5 is provided on the outside of the grinding cylinder 4 . The protective layer 5 is made of polyurethane and is used to keep the grinding cylinder 4 warm and soundproof.

[0042] like Figure 7 As shown, a fixing plate 16 is provided on one side of the discharge port 6 , one side of the fixing plate 16 is fixedly connected to the discharge chute 21 , and a material receiving box 19 is placed on one side of the fixing plate 16 .

[0044] like Figure 7 As shown, a conveyor belt 22 is provided in the discharge trough 21 , and a plurality of second scraper plates 23 are fixedly connected to one side of the conveyor belt 22 .

[0045] Specifically, when the viscous liquid ground material is collected by the material receiving box 19, the conveyor belt 22 is started so that the conveyor belt 22 drives the second scraper plate 23 to continuously scrape the viscous liquid ground material on the discharge trough 21 into the material receiving box 19 for collection and use.

[0046] like Figure 8 As shown, a connecting frame 20 is fixedly connected to one side of the fixed plate 16, a second removal plate 24 is slidably connected in the connecting frame 20, a third spring 27 is fixed in the connecting frame 20, the second removal plate 24 is slidably connected to the third spring 27, the third spring 27 is located on one side of the second removal plate 24 and is slidably connected to a fixed column 28, one end of the fixed column 28 is fixedly connected to the connecting frame 20, and the other end of the fixed column 28 is fixedly connected to the second removal plate 24.

[0047] Specifically, when the second scraper plate 23 scrapes the viscous liquid grinds on the discharge trough 21 into the receiving box 19, the viscous liquid grinds on the conveyor belt 22 are scraped into the receiving box 19 through the second removal plate 24. When the second scraper plate 23 hits the second removal plate 24, the second removal plate 24 will slide into the connecting frame 20 and compress the fixed column 28 through the third spring 27, so that the second removal plate 24 can scrape the viscous liquid grinds on the second scraper plate 23. Embodiment 2

[0050] Specifically, when viscous liquid grounds are collected in the material receiving box 19, the fixed table 18 is reciprocated to make the fixed table 18 reciprocate on the fixed plate 16 through the connecting rods 25 on both sides, and the second springs 26 on both sides are alternately compressed to make the fixed table 18 reciprocate to shake the viscous liquid grounds in the material receiving box 19 flat, thereby preventing the viscous liquid grounds in the material receiving box 19 from accumulating and overflowing from the material receiving box 19 to affect the collection process of the viscous liquid grounds.

[0051] like Fig. 9 As shown, a first motor 17 is fixedly connected to one side of the fixed plate 16, a rotating disk 29 is fixedly connected to the output end of the first motor 17, a connecting column 30 is fixedly connected to one side of the rotating disk 29, a rotating plate 31 is rotatably connected to one side of the connecting column 30, a connecting block 32 is fixedly connected to one side of the fixed platform 18, and the rotating plate 31 is rotatably connected to the connecting block 32.

[0052] Specifically, by starting the first motor 17 to rotate the rotating disk 29 and the connecting column 30, the connecting column 30 rotates through the rotating plate 31 and the connecting block 32 to make the fixed table 18 reciprocate, so that the viscous liquid ground material in the material receiving box 19 can be leveled and the viscous liquid ground material can be better collected.

[0053] Working principle: When wet grinding pigments and ceramic grindings, the liquid is mixed with the grinding raw materials to form a mixed grinding material, and the grinding media such as zirconium oxide beads and the mixed grinding material in the feeding bin 2 are sent to the grinding cylinder 4, and the driving motor 1 is started to make the main shaft 7 rotate with the grinding member 8. The grinding member 8 rotates and drives the zirconium oxide beads to move relative to the mixed grinding material in the grinding cylinder 4, so that the mixed grinding material is effectively dispersed and ground to form a viscous liquid grinding material. The grinding member 8 rotates with the first scraper plate 10 to scrape off the viscous liquid grinding material adhering to the inner wall of the grinding cylinder 4 to prevent the viscous liquid grinding material in the grinding cylinder 4 from adhering to the inner wall of the grinding cylinder 4 and causing insufficient grinding. A protrusion is provided on the upper side of the first removal plate 11 in the grinding cylinder 4 so that the first removal plate 11 will protrude from the inner wall of the grinding cylinder 4. When the viscous liquid grinding material adhering to the inner wall of the grinding cylinder 4 is scraped off by the first scraper plate 10, the first scraper plate 10 will The protruding part of the first material removal plate 11 is pressed against the first material removal plate 11 to make the first material removal plate 11 rotate through the fixing rod 13. When the first material removal plate 11 and the first scraper plate 10 are pressed against and slid, the viscous liquid grinding material adhered to the first scraper plate 10 will be scraped off. The resetting device will make the first material removal plate 11 close to the scraping surface of the first scraper plate 10, so that the first scraper plate 10 can continue to scrape the viscous liquid grinding material adhered to the inner wall of the grinding cylinder 4. After the first material removal plate 11 scrapes the viscous liquid grinding material adhered to the first scraper plate 10, the resetting device resets the first material removal plate 11 into the grinding cylinder 4, and the viscous liquid grinding material adhered to the first scraper plate 10 can be scraped off again so that the viscous liquid grinding material can be fully ground. The fully ground viscous liquid grinding material is discharged from the discharge port 6 to the discharge trough 21, and the reciprocating device drives the discharge trough 21 to reciprocate, so that the viscous liquid grinding material on the discharge trough 21 is quickly collected and utilized.

[0054] When the first scraper plate 10 is used to scrape off the viscous liquid grinding material adhered to the inner wall of the grinding cylinder 4, the first scraper plate 10 will hit the protruding part of the first removal plate 11, causing the first removal plate 11 to rotate through the fixing rod 13, and causing the torsion spring 14 to deform and generate elastic force. After the first removal plate 11 scrapes off the viscous liquid grinding material adhered to the first scraper plate 10, the torsion spring 14 recovers its deformation and causes the first removal plate 11 to rotate back into the grinding cylinder 4, so that the viscous liquid grinding material adhered to the first scraper plate 10 can be scraped off again so that the viscous liquid grinding material can be fully ground. Grinding; the initial position of the reciprocating plate 12 is at the rightmost end of the first removal plate 11, and the initial position of the first removal plate 11 is in a retracted state in the grinding cylinder 4. When the first removal plate 11 rotates through the fixing rod 13, the reciprocating plate 12 will slide on the first removal plate 11 and stretch the first spring 15, sliding the reciprocating plate 12 from the rightmost end of the first removal plate 11 to the left side. When the first removal plate 11 returns to the initial state, the reciprocating plate 12 returns to the initial position. The rightmost end of the first removal plate 11 scrapes off the viscous liquid grinding material adhered to the first removal plate 11;

[0055] By using the shock-absorbing feet 3 made of all carbon steel as the fixed feet of the grinding table 9, the vibration between the grinding table 9 and the ground can be reduced when the grinder is grinding, so as to better protect the grinder, increase the service life of the grinder, and reduce the noise generated during grinding; by arranging the protective layer 5 of polyurethane material on the outer wall of the grinding cylinder 4, the cooling effect inside the grinding cylinder 4 can be better insulated, and the noise generated during grinding of the grinding cylinder 4 can be isolated and eliminated; the viscous liquid grinding material after grinding is discharged from the discharge port 6 through the discharge trough 21 and flows into the collecting box 19 for collection for subsequent processing; after the viscous liquid grinding material is collected by the collecting box 19 When the second scraper plate 23 is driven, the conveyor belt 22 is started so that the conveyor belt 22 drives the second scraper plate 23 to continuously scrape the viscous liquid ground material on the discharge trough 21 into the receiving box 19 for collection and use; when the second scraper plate 23 scrapes the viscous liquid ground material on the discharge trough 21 into the receiving box 19, the viscous liquid ground material on the conveyor belt 22 is scraped into the receiving box 19 through the second removal plate 24, and when the second scraper plate 23 hits the second removal plate 24, the second removal plate 24 will slide into the connecting frame 20 and compress the fixed column 28 through the third spring 27, so that the second removal plate 24 can scrape the viscous liquid ground material on the second scraper plate 23;

[0056] When viscous liquid ground material is collected in the material receiving box 19, the fixed table 18 is reciprocated to make the fixed table 18 reciprocate on the fixed plate 16 through the connecting rods 25 on both sides, and the second springs 26 on both sides are alternately compressed to make the fixed table 18 reciprocate to shake the viscous liquid ground material in the material receiving box 19 flat, so as to prevent the viscous liquid ground material in the material receiving box 19 from accumulating and overflowing from the material receiving box 19 and affecting the collection process of the viscous liquid ground material; by starting the first motor 17 to rotate the rotating disk 29 and drive the connecting column 30 to rotate, the connecting column 30 rotates to make the fixed table 18 reciprocate through the rotating plate 31 and the connecting block 32, so that the viscous liquid ground material in the material receiving box 19 can be shaken flat and the viscous liquid ground material can be better collected.
