[0020] Please see Figure 1-5 A paint mixing and grinding machine includes a grinding shell 1, a mixing shell 2 fixed on the top of the grinding shell 1, a feeding port provided above the mixing shell 2, a return shell 3 connected to the lower left of the surface of the grinding shell 1, and the upper left of the return shell 3 connected to the upper surface of the mixing shell 2.

[0021] The feeding port is used to add materials, the inside of the grinding shell 1 is used to grind the raw materials, the inside of the stirring shell 2 is used to stir and mix the raw materials, and the return shell 3 is used to transport the raw materials.

[0022] A first motor 4 is fixed to the top of the mixing shell 2. The output shaft of the first motor 4 passes through the mixing shell 2 and is fixed to a stirring rod 5. The bottom of the stirring rod 5 is connected to a feeding pipe 6. The surface of the feeding pipe 6 is connected to a first solenoid valve 7 and a second solenoid valve 8. The surface of the second solenoid valve 8 is connected to a discharge pipe 9. The discharge pipe 9 passes through the grinding shell 1. Two first grinding rollers 10 are rotatably connected to the inner wall of the grinding shell 1. A sieve plate 11 is set below the first grinding rollers 10. The sieve plate 11 is fixedly connected to the inner wall of the grinding shell 1. A guide plate 15 is set below the sieve plate 11. The guide plate 15 is fixedly connected to the inner wall of the grinding shell 1. A second motor 16 is fixed to the top of the return shell 3. The output shaft of the second motor 16 passes through the return shell 3 and is fixed to an auger 17. The bottom end of the auger 17 is rotatably connected to the bottom of the inner wall of the return shell 3. A fine grinding structure is set on one side of the grinding shell 1. A drive structure is installed on the surface of the grinding shell 1.

[0023] When the first motor 4 starts, it drives the stirring rod 5 to rotate, allowing the raw materials to be initially mixed and the components to be distributed relatively evenly to form a stable mixture. Then, the first solenoid valve 7 is opened, while the second solenoid valve 8 is closed, allowing the mixed material to fall between the two first grinding rollers 10. The drive structure drives the two first grinding rollers 10 to rotate in opposite directions, allowing the first grinding rollers 10 to initially grind the material. After that, the material falls onto the surface of the sieve plate 11, where the fine grinding structure further grinds the raw material to meet the required grinding requirements. The ground material then falls through the sieve plate 11 onto the surface of the guide plate 15. Afterwards, the raw material will enter the lower part of the return shell 3 through the surface of the guide plate 15. The second motor 16 starts and drives the auger 17 to rotate, so that the material can be transported back to the upper part of the return shell 3 by the auger 17, and re-enter the interior of the mixing shell 2 through the connection between the return shell 3 and the mixing shell 2. At this time, diluent or other auxiliary materials can be added to the interior of the mixing shell 2. Then, the material is stirred and mixed for a longer time by the first motor 4 and the stirring rod 5 so that the coating can reach the required standard. During this period, the first solenoid valve 7 is in the closed state. Afterwards, the second solenoid valve 8 can be opened so that the thoroughly mixed coating can be discharged from the mixing shell 2 through the discharge pipe 9, thus completing the coating stirring operation.

[0024] Furthermore, the surface grinding structure of the grinding shell 1 includes a cylinder 12, which is fixedly connected to the surface of the grinding shell 1. One end of the cylinder 12 passes through the grinding shell 1 and is fixed with a U-shaped plate 13. A second grinding roller 14 is rotatably connected to the inner wall of the U-shaped plate 13.

[0025] By controlling the cylinder 12 to move back and forth, the U-shaped plate 13 can be moved back and forth above the screen plate 11, which allows the second grinding roller 14 to come into contact with the material on the surface of the screen plate 11, so that the second grinding roller 14 can further grind the material, thereby improving the grinding accuracy of the material.

[0026] Furthermore, the surface driving structure of the grinding shell 1 includes a support 18, which is fixedly connected to the surface of the grinding shell 1. A third motor 19 is fixedly fixed to the top of the support 18. A rotating shaft is fixedly fixed to the surface of the first grinding roller 10. The rotating shaft passes through the grinding shell 1. A gear 20 is fixedly fixed to the surface of the rotating shaft. The two gears 20 mesh. The output shaft of the third motor 19 is fixedly connected to the rotating shaft on one side.

[0027] When the third motor 19 is working, it can drive one side of the rotating shaft to rotate. Through the meshing of the two gears 20, the other side of the rotating shaft can also rotate, so that the two first grinding rollers 10 can rotate synchronously in opposite directions, and the first grinding rollers 10 can grind the material normally.

[0028] Furthermore, a side plate 22 is provided above the first grinding roller 10. The side plate 22 is fixedly connected to the inner wall of the grinding shell 1. Both the side plate 22 and the guide plate 15 are designed with an angled inclined structure.

[0029] The inclined side plate 22 can guide the material discharged from the first solenoid valve 7, so that the material can fall between the first grinding rollers 10 on both sides, while the inclined guide plate 15 can guide the material into the return shell 3 by gravity.

[0030] Furthermore, a triangular plate 24 is fixed to the top of the guide plate 15, and a vibration motor 25 is fixed to the bottom of the guide plate 15.

[0031] The design of the triangular plate 24 allows materials falling onto its surface to automatically move towards the surface of the guide plate 15 along the shape of the triangular plate 24. When the vibration motor 25 is started, it can drive the guide plate 15 and the triangular plate 24 to vibrate. The vibration will allow the materials to move more quickly towards the inlet below the return shell 3 along the surface of the guide plate 15, so that the materials can be conveyed on the surface of the guide plate 15.

[0032] Furthermore, a door 21 is hinged to the surface of the grinding shell 1, and two guide rods 23 slide through the surface of the grinding shell 1, with one end of the guide rod 23 fixedly connected to the surface of the U-shaped plate 13.

[0033] After the box door 21 can be opened, the operator will be able to directly clean the surface of the screen plate 11. When the U-shaped plate 13 moves, the guide rod 23 will slide on the surface of the grinding shell 1, so that the U-shaped plate 13 can be guided.

[0034] Working principle: First, the raw materials are added into the mixing shell 2 through the feeding port. The first motor 4 drives the stirring rod 5 to rotate, so that the raw materials can be initially mixed. Then, the first solenoid valve 7 is opened, so that the mixed material can fall between the first grinding rollers 10 on both sides. The first grinding rollers 10 can perform preliminary grinding on the material. Then the material will fall onto the surface of the screen plate 11. The fine grinding structure can further grind the raw materials so that the raw materials can meet the required grinding requirements. The ground material can enter the return shell 3 below through the screen plate 11 and the guide plate 15. The second motor 16 is started, which drives the auger 17 to rotate, so that the material can be transported back into the mixing shell 2 by the auger 17. At this time, diluent or other auxiliary materials can be added into the mixing shell 2. Then, the first motor 4 and the stirring rod 5 will mix the material for a longer time so that the coating can meet the required standards. Then, the second solenoid valve 8 is opened, so that the thoroughly mixed coating is discharged from the mixing shell 2 through the discharge pipe 9, thus completing the coating mixing operation.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
