Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, and more specifically, to a grinding device for anti-adhesion raw materials used in the production of environmentally friendly building wall coatings. Background Technology

[0002] The coatings industry belongs to the fine chemical industry and is an important part of the national economy. The coatings production process includes different stages such as grinding, dispersion, and filling, each with corresponding equipment. The quality of the coatings production equipment is crucial to the product quality and production efficiency.

[0003] When coatings are ground, the grinding rollers of the grinding equipment crush and grind the coatings to reduce the size of the coating particles. Since some coating particles are large in diameter and the grinding rollers rotate in a fixed direction, the coating particles may be crushed into a cake shape and adhere to the surface of the grinding rollers during grinding, resulting in waste of coatings and affecting the grinding effect of the grinding rollers.

[0004] Therefore, in order to solve the above problems, an anti-adhesion raw material grinding device for the production of environmentally friendly building wall coatings is proposed. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide an anti-adhesion raw material grinding device for the production of environmentally friendly building wall coatings. The technical problem to be solved by the present invention is that in the prior art, due to the large particle size of some coating particles and the rotation of the grinding roller along a fixed direction, the coating particles may be crushed into a cake shape and adhere to the surface of the grinding roller during grinding, resulting in waste of coatings and affecting the grinding effect of the grinding roller.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A grinding device for anti-adhesion raw materials used in the production of environmentally friendly building wall coatings includes:

[0008] The storage chamber, grinding chamber, and discharge chamber are fixedly connected from top to bottom. The grinding chamber is equipped with a grinding roller coaxially. A gap is formed between the periphery of the grinding roller and the inner wall of the grinding chamber. The gap is in communication with the storage chamber and the discharge chamber.

[0009] A reciprocating lifting unit is provided in the discharge hopper, which is used to drive the grinding roller to reciprocate and lift when the grinding roller rotates;

[0010] A cover plate connected to the top of the storage compartment has a connecting part coaxially passing through its end face. A transmission rod is connected to the lower end of the connecting part. The lower end of the transmission rod is coaxially fixed to the upper end face of the grinding roller. A motor is mounted on the top of the cover plate through a motor mount. The output shaft of the motor is fixedly connected to the upper end of the connecting part.

[0011] Furthermore, a discharge port is provided on the lower side of the discharge bin.

[0012] Furthermore, the reciprocating lifting unit includes a fixed frame fixed to the inner wall of the discharge hopper, a drive rod coaxially fixed to the lower end of the grinding roller, the lower end of the drive rod passing through the fixed frame and moving freely on the fixed frame, a fixed ring connected to the upper surface of the fixed frame, two fixed pins fixed to the upper end face of the fixed ring, a rotating ring fixedly sleeved around the periphery of the drive rod, an arc-shaped protrusion fixed to the lower end face of the rotating ring, and an elastic abutment unit provided between the fixed ring and the rotating ring, the elastic abutment unit being used to drive the rotating ring to move upward.

[0013] Furthermore, the elastic abutment unit includes a rotating part coaxially rotatably mounted on the fixed ring, and a tension spring is provided between the rotating part and the rotating ring. The two ends of the tension spring in the direction of elastic force are respectively fixed to the lower end face of the rotating ring and the upper end face of the rotating part.

[0014] Furthermore, a ball bearing is rotatably embedded at the top of the fixing pin, and the ball bearing rolls in contact with the lower end face of the rotating ring and the lower surface of the arc-shaped protrusion.

[0015] Furthermore, a limit nut is threaded onto the lower end of the drive rod.

[0016] Furthermore, the connecting part has a first storage cavity, a sliding hole, and a second storage cavity sequentially formed from top to bottom. The upper end of the transmission rod passes through the second storage cavity, the sliding hole, and the first storage cavity and slides freely. The diameter of the sliding hole matches the outer diameter of the transmission rod. Multiple rolling wheels are rotatably connected to the upper periphery of the transmission rod. The wall of the sliding hole has a rolling groove for the rolling wheels to engage. The rolling groove communicates with the first storage cavity and the second storage cavity. The transmission rod is hollow inside, and a first through groove is formed at the end that passes through the second storage cavity. A second through groove is formed on the lower periphery of the transmission rod. The first through groove and the second through groove communicate with the inner cavity of the transmission rod. The connecting part has an inlet that communicates with the first storage cavity. A rotary joint is rotatably fitted on the periphery of the connecting part. The inner cavity of the rotary joint communicates with the inlet.

[0017] Furthermore, multiple locking strips are fixedly connected to the periphery of the upper end of the transmission rod, and a slot is provided in the connecting part for the locking strips to engage.

[0018] Furthermore, a hollow cylinder is fixed to the inner top wall of the first storage cavity, and a connecting cylinder is fixed to the upper periphery of the hollow cylinder. A striking rod is horizontally inserted through the connecting cylinder, and a striking unit for driving the striking rod to reciprocate horizontally is provided inside the hollow cylinder.

[0019] Furthermore, the striking unit includes a sliding rod passing through the bottom of the hollow cylinder. One end of the sliding rod, which enters the hollow cylinder, is fixedly connected to a first piston. The first piston slides freely within the hollow cylinder. A second piston is engaged within the connecting cylinder. The second piston slides freely horizontally within the connecting cylinder. One end of the striking rod, which enters the connecting cylinder, is fixedly connected to the end face of the second piston. A return spring is vertically installed inside the hollow cylinder. The two ends of the return spring, in the direction of its elastic force, respectively abut against the first piston and the top wall of the hollow cylinder.

[0020] The technical effects and advantages of this invention are as follows:

[0021] 1. By setting a reciprocating lifting unit to drive the grinding roller to move back and forth during grinding, the grinding roller can exert grinding force on the paint particles in multiple directions, thus preventing the paint particles from adhering to the surface of the grinding roller.

[0022] 2. By setting the grinding roller to reciprocate up and down, the grinding roller can initially crush the paint particles entering the grinding groove, thereby reducing the particle size of the paint particles and preventing paint particles from adhering to the surface of the grinding roller when grinding larger paint particles.

[0023] 3. By setting the grinding roller to move up and down reciprocally, the top of the transmission rod repeatedly abuts against the sliding rod, which in turn causes the sliding rod to drive the first piston to move inside the hollow cylinder. This causes the air inside the hollow cylinder to push the second piston to move, which in turn causes the second piston to drive the striking rod to move and strike the inner wall of the connecting part, thereby shaking off the paint particles adhering to the grinding groove.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] like Figures 1-10As shown, this embodiment discloses: a grinding device for anti-adhesion raw materials for the production of environmentally friendly building wall coatings, including a storage chamber 4, a grinding chamber 3 and a discharge chamber 2 fixedly connected from top to bottom. The storage chamber 4, grinding chamber 3 and discharge chamber 2 are integrally formed. The discharge chamber 2 has a discharge port 1 on its lower side. In addition, a grinding roller 10 is coaxially arranged in the grinding chamber 3. A gap is formed between the periphery of the grinding roller 10 and the inner wall of the grinding chamber 3. The gap is in communication with the storage chamber 4 and the discharge chamber 2. The top of the storage chamber 4 is open and connected to a cover plate 8. A motor base 7 is connected to the top of the cover plate 8. A motor 6 is vertically installed on the top of the motor base 7. The output shaft of the motor 6 is connected to a connecting part 16. A transmission rod 9 is connected to the lower end of the connecting part 16. The lower end of the transmission rod 9 is coaxially fixedly connected to the upper end of the grinding roller 10. When the output shaft of the motor 6 rotates, it will drive the transmission rod 9 to rotate, so that the transmission rod 9 drives the grinding roller 10 to rotate.

[0037] A fixed frame 12 is fixedly connected to the inner wall of the discharge hopper 2. A drive rod 11 is coaxially fixed to the lower end of the grinding roller 10. The lower end of the drive rod 11 passes through the fixed frame 12 and moves freely on the fixed frame 12. A fixed ring 13 is connected to the upper surface of the fixed frame 12. Two fixed pins 22 are fixed to the upper end face of the fixed ring 13. A rotating ring 15 is fixedly sleeved around the periphery of the drive rod 11. The rotating ring 15 is located above the fixed ring 13. An arc-shaped protrusion 20 is fixed to the lower end face of the rotating ring 15. The two ends of the arc-shaped protrusion 20 smoothly transition with the end face of the rotating ring 15 along the arc length direction. The fixed ring 13 rotates coaxially. A rotating part 14 is embedded in the ground and rotates freely within the fixed ring 13. The rotating part 14 has a through hole coaxially provided for the drive rod 11 to pass through freely. A tension spring 19 is provided between the rotating part 14 and the rotating ring 15. The two ends of the tension spring 19 in the direction of the elastic force are respectively fixed to the lower end face of the rotating ring 15 and the upper end face of the rotating part 14. A ball 21 is rotatably embedded in the top of the fixed pin 22. The ball 21 rolls and contacts the lower end face of the rotating ring 15 and the lower surface of the arc-shaped protrusion 20. A limit nut 18 is threaded onto the lower end of the drive rod 11. The limit nut 18 is used to limit the upward movement of the drive rod 11.

[0038] When the grinding roller 10 rotates, it will synchronously drive the rotating ring 15 to rotate. When the rotating ring 15 rotates, the balls 21 will roll alternately on the lower end face of the rotating ring 15 and the lower surface of the arc-shaped protrusion 20, thereby driving the drive rod 11 to move up and down reciprocally, thus driving the grinding roller 10 to move up and down reciprocally.

[0039] The connecting part 16 has a first storage cavity 25, a sliding hole, and a second storage cavity 28 arranged sequentially from top to bottom inside. The upper end of the transmission rod 9 passes through the second storage cavity 28, the sliding hole, and the first storage cavity 25 and slides freely. The diameter of the sliding hole matches the outer diameter of the transmission rod 9. Multiple rolling wheels 30 are rotatably connected to the upper periphery of the transmission rod 9. The wall of the sliding hole has a rolling groove 29 for the rolling wheels 30 to engage. The rolling groove 29 communicates with the first storage cavity 25 and the second storage cavity 28. The transmission rod 9 is hollow inside, and a first through groove 27 is opened at the end that passes through the second storage cavity 28. A second through groove 17 is opened at the lower periphery of the transmission rod 9. The first through groove 27 and the second through groove 17 communicate with the inner cavity of the transmission rod 9. The connecting part 16 has an inlet that communicates with the first storage cavity 25 on its periphery. A rotary joint 5 is rotatably fitted on the periphery of the connecting part 16. The inner cavity of the rotary joint 5 communicates with the inlet. The head 5 is connected to an external paint delivery pump through a pipeline. The paint delivery pump delivers liquid paint to the inner cavity of the rotary joint 5, and then flows into the first storage chamber 25 of the connecting part 16 from the feed port. The paint enters the crushing trough 29. When the transmission rod 9 moves up and down, it will crush the paint in the crushing trough 29 by the crushing wheel 30. During the crushing process, the liquid paint and the crushed paint particles will flow from the crushing trough 29 into the second storage chamber 28, and then into the inside of the transmission rod 9 from the first through groove 27, and then into the storage chamber 4 from the second through groove 17, and then into the gap between the grinding roller 10 and the inner wall of the grinding chamber 3. In addition, multiple locking strips 26 are fixed to the periphery of the upper end of the transmission rod 9. The connecting part 16 has a locking groove for locking strips 26 to engage. By sliding the locking strips 26 in the locking groove, the connecting part 16 can drive the transmission rod 9 to rotate synchronously when it rotates.

[0040] A hollow cylinder 23 is fixedly connected to the inner top wall of the first storage chamber 25. A connecting cylinder 32 is fixedly connected to the upper periphery of the hollow cylinder 23. A striking rod 35 is horizontally inserted through the connecting cylinder 32. A sliding rod 24 is inserted through the bottom of the hollow cylinder 23. A first piston 31 is fixedly connected to one end of the sliding rod 24 inside the hollow cylinder 23. The first piston 31 slides freely inside the hollow cylinder 23. A second piston 34 is engaged inside the connecting cylinder 32. The second piston 34 slides horizontally freely inside the connecting cylinder 32. The striking rod 35 is inserted into the connecting cylinder 32. One end of the inner part is fixed to the end face of the second piston 34. A return spring 33 is vertically installed inside the hollow cylinder 23. The two ends of the return spring 33 in the direction of the elastic force respectively abut against the first piston 31 and the inner top wall of the hollow cylinder 23. In the initial state, the return spring 33 generates a downward elastic abutting force on the first piston 31, which causes the first piston 31 to drive 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 striking rod 35 to move in the direction of retracting into the connecting cylinder 32.

[0041] The working principle of this invention is as follows: When the motor 6 starts, its output shaft rotates, driving 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 it flows into the first storage cavity 25 of the connecting part 16 from the feed port. The paint enters the grinding trough 29. When the connecting part 16 rotates, it synchronously drives the transmission rod 9, the grinding roller 10, and the drive rod 11 to rotate, so that the drive rod 11 drives the rotating ring 15 to rotate, thereby driving the balls 21 to alternately roll on the lower end face of the rotating ring 15 and the arc-shaped convex surface. The surface of block 20 rolls. Specifically, when the ball 21 rolls from the end face of the rotating ring 15 to the lower surface of the arc-shaped protrusion 20, the ball 21 will drive the rotating ring 15 to move upward, so that it can drive the grinding roller 10 to move upward. When the ball 21 rolls from the lower surface of the arc-shaped protrusion 20 to the lower end face of the rotating ring 15, the tension of the tension spring 19 on the rotating ring 15 will cause the rotating ring 15 to drive the drive rod 11 to move downward, which in turn causes the grinding roller 10 to move downward. This process is repeated, so that the grinding roller 10 moves up and down and back and forth.

[0042] After the paint enters the grinding trough 29, the grinding roller 10 drives the transmission rod 9 to move up and down reciprocally, which causes the grinding wheel 30 to crush the paint in the grinding trough 29. During the crushing process, the paint liquid and the crushed paint particles will flow from the grinding trough 29 into the second storage chamber 28, then into the transmission rod 9 through the first through groove 27, and then into the storage chamber 4 through the second through groove 17. Then, they will enter the gap between the grinding roller 10 and the inner wall of the grinding chamber 3, so that the grinding roller 10 grinds the paint that has entered the gap.

[0043] When the transmission rod 9 moves upward, it exerts an upward pushing force on the sliding rod 24, causing the sliding rod 24 to drive the first piston 31 upward. This forces the air in the hollow cylinder 23 into the connecting cylinder 32, which in turn drives the second piston 34 to move outward from the connecting cylinder 32. This causes the striking rod 35 to quickly pass through the connecting cylinder 32 and strike the inner wall of the connecting part 16, generating vibration in the connecting part 16. This vibration causes a certain degree of vibration in the coating particles in the grinding groove 29, allowing the coating particles to fall down more smoothly and enter the second storage chamber 28. The coating, after being ground by the grinding roller 10, enters the discharge bin 2 and then flows out from the discharge port 1 for collection by the staff.
