Technical Field
[0001] This utility model belongs to the field of dispersion and mixing in paint production, and specifically relates to a dispersion and mixing device for paint production. Background Technology
[0002] In paint production, dispersion and mixing are crucial processes that directly affect the uniformity and quality stability of the paint. Traditional mixing devices often employ a single-power-driven structure, leaving room for improvement in the efficiency and uniformity of dispersion and mixing of paint raw materials. With the increasing demands for product performance in the coatings industry, there is an urgent need for equipment capable of multi-dimensional mixing and enhancing the mixing effect of raw materials. The paint production dispersion and mixing device provided by this invention utilizes a dual-motor driven structure with different rotating blocks and mixing rods, combined with a buffer column and rubber scraper design, aiming to optimize the dispersion effect during the mixing process and improve the technological level and product quality of paint production.
[0003] Existing technologies have specifically developed some dispersion and stirring devices for paint production. For example, Chinese patent publication number "CN217248552U" discloses "A dispersion and stirring device for paint production." This device uses a support base to make the rotation of the stirring tank more stable. A first motor drives the stirring tank to rotate, thereby improving the dispersion effect of the paint. A solenoid valve controls the opening and closing of the discharge pipe. A sealing plate and sealing ring prevent accidental paint leakage during the stirring process. An electric push rod drives the support frame to move up and down, thereby controlling the stirring blades to stir up and down in the stirring tank, improving the dispersion effect of the paint. A second motor drives the rotating shaft to rotate in the opposite direction to the stirring tank. The rotating shaft drives the stirring blades to rotate in the stirring tank, thereby stirring the paint.
[0004] Although the electric push rod drives the support frame to move up and down, thereby controlling the stirring blades to stir the paint inside the mixing tank and improving the dispersion effect, and the second motor drives the rotating shaft to rotate in the opposite direction to the mixing tank, thus stirring the paint, the stirring rod cannot effectively scrape off the paint residue on the inner wall of the mixing tank during the stirring process. This results in the paint adhering to the inner wall of the mixing tank for a long time, making it difficult for workers to clean the inside of the mixing tank later. Utility Model Content
[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a paint production dispersion and stirring device to solve the problem of dispersion and stirring in paint production.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A paint production dispersion and mixing device includes a base plate, a support seat fixedly installed on the upper end of the base plate, a protective block fixedly installed inside the support seat on the upper end of the base plate, a second motor fixedly installed inside the protective block, a mixing tank fixedly installed at the end of the support seat away from the base plate, a cover plate fixedly installed on the upper end of the mixing tank, a telescopic cylinder fixedly installed on the upper end of the base plate away from the support seat, a lifting plate fixedly installed on the output shaft of the telescopic cylinder, a first motor fixedly installed on the upper end of the lifting plate away from the output shaft of the telescopic cylinder, a transmission rod fixedly installed on the output shaft of the first motor, rotating blocks fixedly installed at the ends of the transmission rods away from the first motor and the output shafts of the second motor, three mixing rods integrally formed on the outer rings of the two rotating blocks, buffer columns slidably installed inside the ends of the three mixing rods away from the outer rings of the rotating blocks, and rubber scrapers fixedly installed at the ends of the buffer columns away from the mixing rods.
[0008] As a preferred technical solution, a motor slot is provided inside the protective block, and the second motor is fixedly installed inside the protective block through the motor slot. The output shaft of the second motor passes through the bottom of the mixing tank and is fixedly connected to the rotating block.
[0009] As a preferred technical solution, a circular groove is provided at the center of the cover plate, and sealing rings are fixedly installed on both sides of the circular groove. The transmission rod is fixedly connected to the rotating block through the circular groove provided inside the cover plate.
[0010] As a preferred technical solution, each of the multiple stirring rods has a buffer groove inside the end away from the outer ring of the rotating block, and a buffer spring is fixedly installed inside the buffer groove. The end of the buffer spring away from the buffer groove is fixedly installed on the end of the buffer column away from the rubber scraper.
[0011] As a preferred technical solution, the multiple buffer columns are slidably installed inside the multiple stirring rods through buffer grooves, and a sealing isolation pad is provided at one end of the multiple stirring rods near the rubber scraper.
[0012] As a preferred technical solution, the upper and lower ends of the multiple stirring rods are integrally formed with multiple dispersing columns, and the rubber scraper is attached to the inner ring of the stirring tank.
[0013] As a preferred technical solution, a sealing cover is hinged to one side of the upper end of the cover plate, and a handle is integrally formed on one side of the upper end of the sealing cover. A discharge pipe is integrally formed at the bottom of the outer ring of the mixing tank away from the telescopic cylinder, and a control valve is fixedly installed on the upper outer ring of the discharge pipe.
[0014] In summary, the present invention has the following main advantages:
[0015] First, as the stirring rod rotates, the rubber scraper moves accordingly, scraping off the paint adhering to the barrel wall, allowing this part of the paint to re-participate in the mixing process, avoiding paint residue and waste, while also ensuring the inner wall of the mixing barrel is clean, preventing residual paint from hardening and affecting subsequent use;
[0016] Secondly, as the stirring rod rotates, the paint undergoes complex fluid motion within the mixing tank, with raw materials from different areas mixing together. A buffer column is slidably installed inside the end of the stirring rod furthest from the outer ring of the rotating block. A buffer groove and a buffer spring are provided between the buffer column and the stirring rod. When the stirring rod encounters resistance during mixing, such as incompletely dispersed particles in the paint or contact with the tank wall, the buffer column slides within the buffer groove, and the buffer spring compresses, providing cushioning and shock absorption to prevent damage to the stirring rod due to excessive force, while ensuring the stability of the mixing process.

A lifting plate 1 is fixedly installed on the output shaft of the telescopic cylinder 6. A first motor 2 is fixedly installed on the upper end of the side of plate 1 away from the output shaft of telescopic cylinder 6. A transmission rod 4 is fixedly installed on the output shaft of the first motor 2. A rotating block 14 is fixedly installed on the end of the transmission rod 4 away from the first motor 2 and the end of the second motor 18 output shaft. Three stirring rods 13 are integrally formed on the outer ring of the two rotating blocks 14. A buffer column 22 is slidably installed inside the end of the three stirring rods 13 away from the outer ring of the rotating block 14. A rubber scraper 15 is fixedly installed on the end of the buffer column 22 away from the stirring rod 13.
[0026] refer to Figure 3 The protective block 10 has a motor slot 20 inside. The second motor 18 is fixedly installed inside the protective block 10 through the motor slot 20. The output shaft of the second motor 18 passes through the bottom of the mixing tank 8 and is fixedly connected to the rotating block 14, effectively protecting the second motor 18 inside the protective block 10.
[0027] refer to Figure 4 , Figures 5 to 6A circular groove 16 is formed at the center of the cover plate 3. Sealing rings 17 are fixedly installed on both sides of the circular groove 16. The transmission rod 4 is fixedly connected to the rotating block 14 through the circular groove 16 inside the cover plate 3. A buffer groove 21 is formed inside the end of the multiple stirring rods 13 away from the outer ring of the rotating block 14. A buffer spring 23 is fixedly installed inside the buffer groove 21. The end of the buffer spring 23 away from the buffer groove 21 is fixedly installed on the end of the buffer column 22 away from the rubber scraper 15. Multiple dispersing columns 12 are integrally formed at both the upper and lower ends of the multiple stirring rods 13. The rubber scraper 15 is attached to the stirring rod. In the inner ring of the mixing drum 8, as the stirring rod 13 rotates, the rubber scraper 15 moves accordingly, scraping off the paint adhering to the drum wall. This allows the paint to re-participate in the mixing process, preventing paint residue and waste, and ensuring the cleanliness of the inner wall of the mixing drum 8 to prevent residual paint from hardening and affecting subsequent use. As the stirring rod 13 rotates, the paint forms a complex fluid motion within the mixing drum 8, with raw materials from different areas mixing together. A buffer column 22 is slidably installed inside the end of the stirring rod 13 away from the outer ring of the rotating block 14. A buffer groove 21 and a buffer spring 23 are provided between the buffer column 22 and the stirring rod 13. When the stirring rod 13 encounters resistance during the mixing process, such as the presence of incompletely dispersed particles in the paint or contact between the stirring rod 13 and the drum wall, the buffer column 22 can slide within the buffer groove 21, and the buffer spring 23 is compressed, providing a buffering and shock-absorbing effect to prevent damage to the stirring rod 13 due to excessive force, while ensuring the stability of the mixing process.
[0028] refer to Figures 1 to 2 A sealing cover 5 is hinged to one side of the upper end of the cover plate 3. A handle 7 is integrally formed on one side of the upper end of the sealing cover 5. A discharge pipe 26 is integrally formed at the bottom of the outer ring of the mixing tank 8 away from the telescopic cylinder 6. A control valve 25 is fixedly installed on the upper outer ring of the discharge pipe 26. Before using the mixing device, the sealing cover 5 hinged to the upper end of the cover plate 3 must be opened first. It is very convenient to open and operate by using the handle 7. After the discharge is completed, the control valve 25 is closed to prevent paint residue or leakage.
[0029] Operating principle and advantages: Before using this mixing device, the sealing cover 5 hinged at the top of the cover plate 3 must be opened. The operation is very convenient via the handle 7. Pour the paint material to be mixed into the mixing tank 8 through the top opening, then close the sealing cover 5 to ensure that the material does not splash or overflow during mixing, while maintaining a relatively sealed environment inside the mixing tank 8 to reduce the entry of external impurities and ensure paint quality. The device consists of a first motor 2 and a second motor 18. A telescopic cylinder 6 is fixed on the upper end of the base plate 9 away from the support base 11. Its output shaft drives the lifting plate 1 to move, and the first motor 2 installed on the lifting plate 1 rises and falls accordingly. When the first motor 2 is in the appropriate position, its output shaft is connected to the rotating block 14 inside the mixing tank 8 via the transmission rod 4. At this time, the output shaft of the second motor 18 in the protective block 10 inside the support base 11 on the bottom plate 9 passes through the bottom of the mixing tank 8 and is fixedly connected to another rotating block 14. After the motor is started, the first motor 2 and the second motor 18 drive their respective connected rotating blocks 14 to rotate, forming a dual-power mixing source to provide sufficient power for paint mixing. The outer ring of each of the two rotating blocks 14 is integrally formed with three stirring rods 13. Driven by the rotating blocks 14, these stirring rods 13 begin to rotate at high speed. The dispersion columns 12 integrally formed at the upper and lower ends of the stirring rods 13 increase the contact area with the paint raw materials. During the rotation, the paint is initially dispersed and stirred, breaking up large pieces of raw materials and accelerating the mixing process. As the stirring rods 13 rotate, the paint forms in the mixing tank 8. In complex fluid motion, raw materials from different regions mix and blend. A buffer column 22 is slidably installed inside the end of the stirring rod 13 furthest from the outer ring of the rotating block 14. A buffer groove 21 and a buffer spring 23 are provided between the buffer column 22 and the stirring rod 13. When the stirring rod 13 encounters resistance during stirring, such as incompletely dispersed particles in the paint or contact with the barrel wall, the buffer column 22 can slide within the buffer groove 21, and the buffer spring 23 is compressed, providing a buffering and shock-absorbing effect to prevent damage to the stirring rod 13 due to excessive force, while ensuring the stability of the stirring process. A rubber scraper 15 is fixedly installed at the end of the buffer column 22 furthest from the stirring rod 13, tightly fitting against the inner ring of the mixing barrel 8. As the stirring rod 13 rotates, the rubber scraper 15 moves accordingly, dispersing and reducing the impact of the friction. Paint adhering to the barrel wall is scraped off, allowing this portion of paint to be re-mixed, avoiding paint residue and waste. This also ensures the inner wall of the mixing barrel 8 is clean, preventing residual paint from hardening and affecting subsequent use. A motor slot 20 is provided inside the protective block 10, through which the second motor 18 is fixedly installed. This effectively isolates the motor from the paint material, preventing paint from entering the motor and damaging it, while also providing some protection and extending the motor's lifespan. Sealing rings 17 are fixedly installed on both sides of the circular groove 16 at the center of the cover plate 3. When the transmission rod 4 passes through the circular groove 16 and connects to the rotating block 14, the sealing rings 17 prevent paint leakage from the connection point, ensuring the sealing of the mixing barrel 8 and maintaining a good mixing environment.A sealing gasket 24 is installed at the end of the stirring rod 13 near the rubber scraper 15 to further prevent paint from entering the buffer tank 21 and protect the normal operation of components such as the buffer spring 23. After the paint is stirred, the control valve 25 on the discharge pipe 26 at the bottom of the outer ring of the stirring tank 8, away from the telescopic cylinder 6, is opened. Under the action of gravity, the evenly stirred paint flows out from the discharge pipe 26 and enters the subsequent packaging or storage stage. After the discharge is completed, the control valve 25 is closed to prevent paint residue or leakage.
