Description

Technical Field

[0001] The invention relates to the technical field of paint production, and in particular to a raw material stirring device and a stirring process for paint coating production. Background Art

[0002] Paint is a mixture of raw materials such as pigments, resins, solvents and additives, which is used to coat the surface of objects to play a protective, decorative and specific functional role, such as waterproofing, anti-corrosion, heat insulation, etc. There are many types of paint, including solvent-based paint, water-based paint, powder coating, etc. Paints with different formulas have different physical properties and uses. In the production process of paint, the mixing uniformity of raw materials directly affects the quality of the final product. These raw materials have different properties, such as viscosity, density, and particle size. It is difficult to achieve the ideal mixing effect by manual or simple equipment alone, so special mixing equipment is required. The mixing equipment can effectively solve the problems of pigment deposition and uneven resin dispersion by fully stirring and homogenizing the raw materials, while improving the stability and fluidity of the coating, ensuring the performance of the coating during construction.

[0003] In the prior art, a Chinese patent document with publication number CN117983097A discloses a raw material stirring device and stirring process for producing paints and coatings. When the materials are stirred and mixed, a driving member drives the barrel cover to rise, so that a negative pressure environment can be formed inside the outer barrel body. In the process of the material flowing from the upper side of the inner barrel body to between the inner barrel body and the outer barrel body, since the distance between the bubbles and the materials is very small at this time, the negative pressure environment can make the bubbles move up and rupture more smoothly in the process, thereby making the bubble elimination more efficient. As the bubbles rupture one after another, the negative pressure environment in the outer barrel body disappears. At this time, the driving member drives the barrel cover to move downward, which can open the exhaust hole, causing the gas in the outer barrel body to be discharged from the exhaust hole. Then, the driving member drives the barrel cover to rise again, and the sealing cover will re-block the exhaust hole. , which can form a negative pressure environment in the outer barrel again, so that the stirring device has the characteristics of stable and efficient defoaming, and can reduce the damage to the environment, human health, and coating quality. However, consistent with the traditional method, the traditional stirring device usually relies on manual or extensive mechanical feeding, resulting in large errors in raw material metering, which makes it difficult to meet the high requirements of paint and coating production on the accuracy of raw material ratios. When the raw materials fall, there is a lack of buffer structure and dynamic reset function, which often causes the feed pipe to be blocked or the device to be damaged due to excessive impact force, affecting the stable operation of the equipment. In addition, traditional stirring devices mostly use a single scraper or a simple stirring paddle, which cannot clean up the materials accumulated at the bottom or attached to the inner wall, resulting in uneven mixing and even a large amount of residual material, causing waste. Therefore, the present application discloses a raw material stirring device and a stirring process for paint and coating production. Summary of the invention

[0027] like Figures 1 to 9 As shown, a raw material stirring device for paint coating production includes a processing cylinder 1, a plurality of supporting legs 2 are arranged at the bottom of the processing cylinder 1, a mixing tank 3 is arranged at the top of the processing cylinder 1, and a discharge port 34 is arranged on one side of the processing cylinder 1; a stirring component, the stirring component is arranged inside the mixing tank 3, and the stirring component is used to stir the raw materials; a quantitative feeding component, the quantitative feeding component is arranged above the processing cylinder 1, and the quantitative feeding component includes a feeding module and a quantitative conveying module, the feeding module is used to convey the production raw materials to the inside of the quantitative conveying module, and the quantitative conveying module is used to quantitatively separate the materials fed by the feeding module and convey them to the inside of the mixing tank 3; In the production process, the raw materials first enter the quantitative conveying module through the feeding module. The feeding module is responsible for conveying the production raw materials to the inside of the quantitative conveying module. The quantitative conveying module separates the raw materials delivered by the feeding module and conveys the materials to the mixing tank 3 at the top of the processing cylinder 1 according to the set amount. After the mixing tank 3 receives the raw materials fed by the quantitative conveying module, the stirring component starts to run and fully stirs the raw materials. The rotating design of the stirring component ensures the uniform mixing of the raw materials to prevent stratification or particle agglomeration. After stirring, the uniformly mixed materials are discharged through the discharge port 34 on the side of the processing cylinder 1 to complete the entire production process. In this process, the cooperation of the quantitative feeding component and the stirring component ensures that the proportion of each batch of raw materials is accurate and uniformly mixed, and high-quality paint and coating production is achieved. The stirring component is arranged inside the mixing tank 3, which can fully stir the production raw materials entering the mixing tank 3, ensure that all kinds of raw materials are evenly mixed, improve the production quality of paint and coating, and avoid product performance fluctuations due to uneven distribution of raw materials. It integrates the functions of feeding, conveying, quantitative separation and stirring, reduces the conversion links between equipment, reduces the complexity of manual operation, and improves production efficiency at the same time to meet the needs of large-scale industrial production.

[0028] like Figure 2 , Figure 6 , Figure 8 As shown, the stirring assembly includes a rotating block 4 rotatably installed at the lower part of the mixing tank 3, a rotating motor is arranged on the bottom end surface of the processing cylinder 1, the output end of the rotating motor passes through the processing cylinder 1 to the inside of the mixing tank 3, and the output end of the rotating motor is fixedly connected to the rotating block 4, and the outer surface of the rotating block 4 is respectively provided with a first scraper 5, a connecting rod 6 and a third scraper 8, the first scraper 5 is arranged in an inclined shape, and the bottom surface of the first scraper 5 is in contact with the bottom surface of the mixing tank 3, the connecting rod 6 is arranged in an angled shape, and the other end of the connecting rod 6 is fixedly installed with a second scraper 7, one side of the second scraper 7 is arranged in an inclined shape and is in contact with the inner wall of the mixing tank 3, and the third scraper 8 is arranged in a curved surface shape, which is used for auxiliary stirring of the inside of the mixing tank 3 and pushing out the material; During the production process, the rotating motor is started, and its output end drives the rotating block 4 installed at the lower part of the mixing tank 3 to rotate. The rotation of the rotating block 4 causes the first scraper 5, the connecting rod 6, the second scraper 7 and the third scraper 8 installed on its outer surface to start working in sequence. The first scraper 5 is designed to be inclined and contacts the bottom surface of the mixing tank 3. As the rotating block 4 rotates, it sweeps across the bottom, removes the accumulated materials and flips them upwards, so that the bottom materials participate in the mixing; the connecting rod 6 transmits the stirring force to the second scraper 7 through its angled design, and the second scraper 7 and the inner wall of the mixing tank 3 are connected. During the rotation, the scrapers clean the materials attached to the inner wall and push them to the center of the mixing tank 3. Due to the curved structure of the third scraper 8, disturbances are generated when the materials flow inside the mixing tank 3, which helps to mix the materials evenly. At the same time, its pushing function transports the mixed materials toward the discharge port 34 of the processing cylinder 1. During the whole mixing process, the scrapers work together to complete the comprehensive mixing and efficient output of the materials through bottom cleaning, inner wall scraping, internal disturbance and pushing, ensuring that the materials in the mixing tank 3 are evenly distributed and discharged smoothly in a short time.

[0029] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, the feeding module includes a fixed frame 9 fixedly mounted on the upper end of the processing cylinder 1, a feeding hopper 10 is fixedly mounted on the top of the fixed frame 9, a movable plate 11 is arranged in the middle of the fixed frame 9, a plurality of return springs 12 are arranged at the bottom of the movable plate 11, the other ends of the plurality of return springs 12 are fixedly connected to the fixed frame 9, a receiving and discharging hopper 13 for receiving the raw materials dropped from the feeding hopper 10 is arranged on the top of the movable plate 11, and the quantitative conveying module includes a driving motor 14 fixedly mounted on the lower end of the fixed frame 9, and a fixed material dividing plate 15 vertically slidably mounted on one side of the fixed frame 9. A raw material feed pipe 26 is also provided on one side of the fixed frame 9, the bottom of which penetrates the processing cylinder 1 to the interior of the mixing tank 3, a through hole is opened on one side of the fixed dividing plate 15 corresponding to the top of the raw material feed pipe 26, a rotating dividing plate 16 is also rotatably installed above the fixed dividing plate 15, the rotating dividing plate 16 is fixedly sleeved on the outer surface of the output end of the driving motor 14, and a plurality of quantitative channels 17 are provided on the rotating dividing plate 16, the bottom ends of the plurality of quantitative channels 17 are in contact with the top end surface of the fixed dividing plate 15, and the quantitative channels 17 are arranged as a telescopic sleeve structure; During operation, the raw material first enters the receiving and discharging hopper 13 from the feeding hopper 10. The receiving and discharging hopper 13 buffers the impact force of the raw material through the movable plate 11 fixed in the middle of the fixed frame 9. The movable plate 11 is slightly pressed down due to the support of the return spring 12 during feeding, and quickly rebounds to the initial position after the raw material passes through, ensuring a stable material receiving process. The received raw material enters the quantitative channel 17 of the quantitative conveying module from below the receiving and discharging hopper 13. After the driving motor 14 is started, it drives the rotating dividing plate 16 fixedly mounted at its output end to rotate, and the quantitative The channel 17 passes through the through-hole positions of the fixed material distribution plate 15 one by one, and accurately and quantitatively discharges the raw materials into the through-holes of the fixed material distribution plate 15. After passing through the through-holes of the fixed material distribution plate 15, the raw materials directly fall into the raw material feeding pipe 26, and are transported to the inside of the mixing tank 3 along the pipeline. The quantitative channel 17 is designed as a telescopic sleeve structure, which cooperates with the fixed material distribution plate 15 that can be vertically slidably arranged (the sliding structure adopts a screw structure, etc., which is the existing technology). If it is necessary to adjust its own volume according to the volume of the raw materials, the fixed material distribution plate 15 can be adjusted to rise and fall synchronously to drive the quantitative channel 17 to expand and contract; A rotating gear 18 is also fixedly installed on the top of the output end of the driving motor 14, and a plurality of positioning gears 19 meshing with the rotating gear 18 are rotatably installed in the middle of the top of the rotating dividing plate 16. A rotating sleeve 20 is also rotatably installed in the middle of the top of the rotating dividing plate 16, and the inner side of the rotating sleeve 20 is provided with teeth meshing with a plurality of rotating sleeves 20. A plurality of stirring scrapers 21 are provided on the outer surface of the rotating sleeve 20. A positioning block 22 is fixedly installed below the discharging hopper near the rotating dividing plate 16. The positioning block 22 is arranged in an arc shape, and an inclined positioning groove 23 is provided on one side of the positioning block 22 near the rotating dividing plate 16. A fixing rod 24 is fixedly installed on one side of the top surface of the rotating sleeve 20, and a positioning rod 25 adapted to the positioning groove 23 is fixedly installed on one side of the fixing rod 24. When the driving motor 14 is started, the output shaft drives the rotating gear 18 sleeved thereon to rotate. The rotating gear 18 drives the positioning gear 19 to rotate synchronously by meshing with the three positioning gears 19. The positioning gear 19 further drives the rotating sleeve 20 to rotate in the reverse direction through the meshing teeth on its outer side. The outer surface of the rotating sleeve 20 is equipped with a scraper. The scraper stirs the compound feed additive during the reverse rotation process and scrapes the stirred material into the quantitative channel 17 to ensure that the raw materials are evenly distributed and quantitatively transported. At the same time, the fixed rod 24 on one side of the top surface of the rotating sleeve 20 drives the positioning rod 25 to slide into the inclined positioning groove 23 on the positioning block 22. As the positioning rod 25 slides, the positioning block 22 is pulled by the inclination angle of the positioning slot 23 to move downward, driving the discharge hopper to be pressed down synchronously. When the positioning rod 25 slides to the end in the positioning slot 23, it disengages from the positioning slot 23. The discharge hopper is quickly reset under the action of the first return spring 12, and bounces slightly several times to ensure that the material accumulation problem is cleared and the material discharge is further guaranteed to be smooth. During the whole process, the decelerated rotation of the rotating sleeve 20 ensures the stability and accuracy of the scraper stirring and material discharge, and the dynamic adjustment mechanism of the positioning block 22 and the return spring 12 provides a reliable anti-blocking function for the discharge hopper, realizing an efficient and smooth material processing process.

The closing block 29 cooperates with the slide 30 through the rotating wheels on both sides of the guide rod 31, and completes precise linear motion under the drive of the cylinder 28. The side of the closing block 29 close to the processing cylinder 1 is designed to be arc-shaped, matching the shape of the discharging port 34. When the closing block 29 slides to the closed position, it fits tightly with the discharging port 34, completely closing the discharging channel to prevent material leakage. When it is necessary to open the discharging, the cylinder 28 drives the closing block 29 to telescope outwards and close it. The block 29 moves smoothly along the guide track provided by the guide rod 31 and the slide groove 30, gradually opens the discharge port 34, and the material smoothly enters the discharge bin 32 at the bottom of the discharge box 27. The vacuum barrier 33 inside the guide rod 31 prevents the external environment from affecting the guide structure. At the same time, the vacuum barrier 33 between the processing cylinder 1 and the mixing tank 3 ensures the quality stability of the material under a controlled environment. After the discharge is completed, the cylinder 28 drives the closing block 29 to return to its position. The closing block 29 is supported by the slide groove 30 and fits with the discharge port 34 again, closing the discharge channel to complete the entire discharge process.
