[0037] The inner wall of the discharge bin 2 is fixedly connected with a fixed frame 12, and the lower end of the grinding roller 10 is coaxially fixed with a driving rod 11, and the lower end of the driving rod 11 is penetrated by the fixed frame 12 and moves freely on the fixed frame 12. The upper surface of the fixed frame 12 is connected with a fixed ring 13, and the upper end surface of the fixed ring 13 is fixedly connected with two fixing pins 22. The periphery of the driving rod 11 is fixedly sleeved with a rotating ring 15, and the rotating ring 15 is located above the fixed ring 13. The lower end surface of the rotating ring 15 is fixedly connected with an arc-shaped protrusion 20, and the two ends of the arc-shaped protrusion 20 in the arc length direction are smoothly transitioned with the end surface of the rotating ring 15. The fixed ring 13 is coaxially rotating. A rotating part 14 is embedded in the fixed ring 13, and the rotating part 14 rotates freely in the fixed ring 13. A through hole is coaxially opened in the rotating part 14 for the driving rod 11 to pass freely. A tension spring 19 is arranged between the rotating part 14 and the rotating ring 15. The two ends of the tension spring 19 in the elastic force direction are respectively fixed to the lower end surface of the rotating ring 15 and the upper end surface of the rotating part 14.

[0039] The interior of the connecting portion 16 is provided with a first material storage cavity 25, a sliding hole, and a second material storage cavity 28 in sequence from top to bottom. The upper end of the transmission rod 9 penetrates into the second material storage cavity 28, the sliding hole and the first material storage cavity 25 and slides freely. The aperture of the sliding hole matches the outer diameter of the transmission rod 9. A plurality of rolling wheels 30 are rotatably connected to the periphery of the upper end of the transmission rod 9. A rolling groove 29 for the rolling wheel 30 to engage is provided on the hole wall of the sliding hole. The rolling groove 29 is communicated with the first material storage cavity 25 and the second material storage cavity 28. The interior of the transmission rod 9 is hollow and a first through groove 27 is provided at one end thereof that penetrates into the second material storage cavity 28. A second through groove 17 is provided at the periphery of the lower end of the transmission rod 9. The first through groove 27 and the second through groove 17 are communicated with the inner cavity of the transmission rod 9. A feeding port that is communicated with the first material storage cavity 25 is provided at the periphery of the connecting portion 16. A rotary joint 5 is rotatably mounted on the periphery of the connecting portion 16. The inner cavity of the rotary joint 5 is communicated with the feeding port. The head 5 is connected to an external paint delivery pump through a pipeline. The paint delivery pump delivers the paint liquid to the inner cavity of the rotary joint 5, and then flows into the first storage cavity 25 of the connecting part 16 from the feed port, and the paint enters the rolling groove 29. When the transmission rod 9 reciprocates up and down, the rolling wheel 30 will crush and grind the paint in the rolling groove 29. During the crushing process, the paint liquid and the crushed paint particles will flow from the rolling groove 29 into the second storage cavity 28, and then enter the inside of the transmission rod 9 from the first through groove 27 of the transmission rod 9, and then flow into the storage bin 4 from the second through groove 17, and then enter the gap between the grinding roller 10 and the inner wall of the grinding bin 3. In addition, a plurality of clips 26 are fixedly connected to the periphery of the upper end of the transmission rod 9, and a clip groove for the clips 26 to engage is opened in the connecting part 16. The clips 26 slide in the clip groove, so that when the connecting part 16 rotates, the transmission rod 9 can be synchronously driven to rotate;

[0040] The inner top wall of the first material storage chamber 25 is fixedly connected with a hollow cylinder 23, the upper peripheral edge of the hollow cylinder 23 is fixedly connected with a connecting cylinder 32, a knocking rod 35 is horizontally penetrated on the connecting cylinder 32, a sliding rod 24 is penetrated at the bottom of the hollow cylinder 23, one end of the sliding rod 24 penetrated into the hollow cylinder 23 is fixedly connected with a first piston 31, the first piston 31 slides freely in the hollow cylinder 23, a second piston 34 is engaged in the connecting cylinder 32, the second piston 34 slides freely horizontally in the connecting cylinder 32, and the knocking rod 35 penetrates into the connecting cylinder 32 One end is fixedly connected to the end face of the second piston 34, and a return spring 33 is vertically installed in the hollow cylinder 23. The two ends of the return spring 33 in the elastic direction respectively press against the first piston 31 and the top wall inside the hollow cylinder 23. In the initial state, the return spring 33 generates a downward elastic pressing force on the first piston 31, so that the first piston 31 drives the sliding rod 24 to move downward, so that the air in the connecting cylinder 32 enters the hollow cylinder 23, and then drives the knocking rod 35 to move in the direction of retracting into the connecting cylinder 32.

[0041] The working principle of the present invention is as follows: when the motor 6 is started, its output shaft rotates and drives the connecting part 16 to rotate, the paint delivery pump delivers the paint liquid to the inner cavity of the rotary joint 5, and then flows into the first storage cavity 25 of the connecting part 16 from the feed port, and the paint enters the rolling groove 29. When the connecting part 16 rotates, it will synchronously drive the transmission rod 9, the grinding roller 10 and the driving rod 11 to rotate, so that the driving rod 11 drives the rotating ring 15 to rotate, and then drives the ball 21 to alternately rotate on the lower end surface of the rotating ring 15 and the arc convex surface. The surface of the block 20 rolls. Specifically, when the ball 21 rolls from the end surface of the rotating ring 15 to the lower surface of the arc-shaped protrusion 20, the ball 21 drives the rotating ring 15 to move upward, so that the grinding roller 10 can be driven to move upward. When the ball 21 rolls from the lower surface of the arc-shaped protrusion 20 to the lower end surface of the rotating ring 15, the pulling force of the tension spring 19 on the rotating ring 15 makes the rotating ring 15 drive the driving rod 11 to move downward, and then the grinding roller 10 moves downward. This is repeated, so that the grinding roller 10 moves up and down reciprocatingly.

[0042] After the paint enters the rolling groove 29, the grinding roller 10 drives the transmission rod 9 to reciprocate up and down, so that the rolling wheel 30 rolls and crushes the paint in the rolling groove 29. During the crushing process, the paint liquid and the crushed paint particles will flow from the rolling groove 29 into the second storage cavity 28, and then enter the inside of the transmission rod 9 from the first through groove 27 of the transmission rod 9, and then flow into the storage bin 4 from the second through groove 17, and then enter the gap between the grinding roller 10 and the inner wall of the grinding bin 3, so that the grinding roller 10 grinds the paint entering the gap;

[0043] When the transmission rod 9 moves upward, the transmission rod 9 will generate an upward resisting force on the sliding rod 24, so that the sliding rod 24 drives the first piston 31 to move upward, thereby squeezing the air in the hollow cylinder 23 into the connecting cylinder 32, thereby driving the second piston 34 to move in the connecting cylinder 32 toward the outside of the connecting cylinder 32, and making the knocking rod 35 quickly pass through the connecting cylinder 32, so that the knocking rod 35 knocks on the inner wall of the connecting part 16, so that a vibration force is generated in the connecting part 16, thereby generating a certain degree of vibration on the paint particles in the rolling groove 29, so that the paint particles can fall down more smoothly and enter the second storage chamber 28. The paint ground by the grinding roller 10 enters the discharge bin 2, and then flows out from the discharge port 1 and is collected by the staff.
