[0001] This utility model relates to the technical field of paint production and processing, and in particular to a grinding and dispersing device for paint production. Background Technology

[0002] Paint is composed of resin, solvent, pigment, additives, etc. In the current paint production process, the raw materials need to be ground and dispersed. Fineness and uniformity are important factors affecting the quality of paint, and they have a great impact on film quality, gloss, durability and storage stability of paint.

[0003] In existing preparation processes, grinding and dispersion steps are mostly carried out separately. After the raw materials are ground and taken out, they are dispersed by dispersion equipment to make the powder uniform. This processing method leads to low production efficiency and insufficient practicality. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a grinding and dispersing equipment for paint production that can effectively improve the production and processing efficiency of grinding and dispersing paint coatings and has higher practicality.

[0005] Technical solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a grinding and dispersing device for paint production, comprising a shell and a grinding and dispersing mechanism. The bottom of the shell has an arc-shaped structure, and four sets of support legs are fixedly connected to both sides of the front end of the shell. A grinding cylinder is fixedly connected between the left and right ends inside the shell. A feeding pipe is fixedly connected to the top of the grinding cylinder, and the feeding pipe is fixedly installed on the top of the shell. A feeding hopper is fixedly connected to the input end of the feeding pipe. Screen holes are evenly opened at the bottom of the grinding cylinder. A discharge pipe is fixedly connected to the right side of the bottom end of the shell, and a discharge valve is provided on the discharge pipe. The grinding and dispersing mechanism includes a motor and a grinding roller. The motor is fixedly connected to the grinding cylinder. Installed on the right end of the outer casing, the grinding roller is eccentrically and symmetrically fixedly connected to the right and left ends of the drive shaft and driven shaft, respectively. The grinding roller is rotatably installed in the grinding cylinder through the drive shaft and driven shaft. The drive shaft and driven shaft are coaxial with the grinding cylinder. The outer wall of the grinding roller abuts against the inner wall of the grinding cylinder, and the right end of the drive shaft is fixedly connected to the motor output end. A stirring rod is rotatably installed on the lower side inside the outer casing. The left end of the stirring rod passes through the outer casing. A large synchronous pulley is fixedly connected to the left side of the driven shaft, and a small synchronous pulley is fixedly connected to the left end of the stirring rod. A synchronous belt is driven onto the large and small synchronous pulleys. Multiple sets of stirring blades are fixedly connected at equal intervals on the outer wall of the stirring rod.

[0007] Preferably, the feeding hopper is tightly covered with an end cap, and a cap handle is fixedly connected to the top of the end cap.

[0008] Preferably, an observation window is fixedly installed on the front of the outer casing.

[0009] Preferably, a protective cover is installed on the left end of the housing by means of screw connection, and the protective cover covers the large synchronous pulley and the synchronous belt.

[0010] Preferably, a reinforcing rod is fixedly connected between the inner side of each of the four sets of support legs and the bottom end of the outer shell.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, the paint and coating raw materials are added to the grinding cylinder through the feeding hopper and feeding pipe. By starting the motor, the motor can drive the grinding roller to rotate inside the grinding cylinder against the inner wall of the grinding cylinder with the driving shaft as the axis. Through the rotation of the grinding roller, the raw materials are ground in cooperation with the grinding cylinder. The grinding particles are screened through the sieve holes at the bottom of the grinding cylinder. The particles that meet the size requirements fall to the bottom of the outer shell through the sieve holes, while those that do not meet the size requirements continue to be ground in the grinding cylinder. The ground powder falls to the bottom of the outer shell. The driven shaft drives the stirring rod to rotate through the transmission of the large synchronous pulley, the small synchronous pulley and the synchronous belt. The stirring rod stirs the powder through the stirring blades, so that the ground powder is dispersed, avoiding accumulation and making the powder uniformly mixed. In this way, the raw materials can be dispersed directly after grinding, combining grinding and dispersion, effectively improving the production and processing efficiency of paint and coating grinding and dispersion, and making it more practical.

[0018] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0019] Example

[0020] Please see Figures 1-5 This utility model discloses a grinding and dispersing device for paint production, comprising a housing 1, a motor 9, and a grinding roller 10. The bottom of the housing 1 has an arc-shaped structure. Four sets of support legs 2 are fixedly connected to both sides of the front end of the housing 1. A grinding cylinder 3 is fixedly connected between the left and right ends inside the housing 1. A feeding pipe 4 is fixedly connected to the top of the grinding cylinder 3. The feeding pipe 4 is fixedly installed on the top of the housing 1. A feeding hopper 5 is fixedly connected to the input end of the feeding pipe 4. Screen holes 6 are evenly opened at the bottom of the grinding cylinder 3. A discharge pipe 7 is fixedly connected to the right side of the bottom end of the housing 1. A discharge valve 8 is installed on the discharge pipe 7. The motor 9 is fixedly installed on the outer casing. At the right end of the shell 1, the right and left ends of the grinding roller 10 are respectively eccentrically and symmetrically fixedly connected to a drive shaft 11 and a driven shaft 12. The grinding roller 10 is rotatably mounted in the grinding cylinder 3 via the drive shaft 11 and the driven shaft 12. The drive shaft 11 and the driven shaft 12 are coaxial with the grinding cylinder 3. The outer wall of the grinding roller 10 abuts against the inner wall of the grinding cylinder 3, and the right end of the drive shaft 11 is fixedly connected to the output end of the motor 9. A stirring rod 13 is rotatably mounted inside the lower side of the shell 1. The left end of the stirring rod 13 passes through the shell 1. A large synchronous pulley 14 is fixedly connected to the left side of the driven shaft 12, and a small synchronous pulley 1 is fixedly connected to the left end of the stirring rod 13. 5. A synchronous belt 16 is installed on the transmission sleeve of the large synchronous pulley 14 and the small synchronous pulley 15. Multiple sets of stirring blades 17 are fixedly connected at equal intervals on the outer wall of the stirring rod 13. In use, the paint raw materials are added into the grinding cylinder 3 through the feeding hopper 5 and the feeding pipe 4. By starting the motor 9, the motor 9 can drive the grinding roller 10 to rotate inside the grinding cylinder 3 around the driving shaft 11, against the inner wall of the grinding cylinder 3. Through the rotation of the grinding roller 10, the raw materials are ground in cooperation with the grinding cylinder 3. The ground particles are screened through the sieve holes 6 at the bottom of the grinding cylinder 3. The particles that meet the size requirements are then screened. The powder falls through the sieve holes 6 to the bottom of the inner shell 1. Any powder that does not meet the requirements continues to be ground in the grinding cylinder 3. The ground powder falls to the bottom of the outer shell 1. The driven shaft 12 drives the stirring rod 13 to rotate through the transmission of the large synchronous pulley 14, the small synchronous pulley 15 and the synchronous belt 16. The stirring rod 13 stirs the powder through the stirring blades 17, dispersing the ground powder and preventing it from piling up into lumps. This ensures that the powder is mixed evenly, allowing the raw materials to be dispersed directly after grinding. This combines grinding and dispersion, effectively improving the production efficiency of paint and coating grinding and dispersion, and making it more practical.

[0021] The feeding hopper 5 is tightly covered with an end cap 18, and a cover handle 19 is fixedly connected to the top of the end cap 18. By setting the end cap 18 and the cover handle 19, after the raw material is added, the end cap 18 can be placed on the feeding hopper 5 to prevent the raw material from running out during the grinding process.

[0022] An observation window 20 is fixedly installed on the front of the outer shell 1; by setting the observation window 20, the grinding and dispersion of the raw materials inside the outer shell 1 can be easily observed, so that the discharge valve 8 can be opened in time to discharge the raw materials.

[0023] A protective cover 21 is installed on the left end of the outer casing 1 by means of screw connection, and the protective cover 21 covers the large synchronous pulley 14 and the synchronous belt 16; by setting the protective cover 21, the operation of the large synchronous pulley 14 and the synchronous belt 16 can be protected, thereby improving the safety of use.

[0024] Each of the four sets of support legs 2 has a reinforcing rod 22 fixedly connected to the bottom of the outer shell 1; by setting the reinforcing rod 22, the connection between the support leg 2 and the outer shell 1 can be made more firm and stable.

[0025] This utility model discloses a grinding and dispersing device for paint production. Its working principle is as follows: During use, paint raw materials are added to the grinding cylinder 3 through the feeding hopper 5 and feeding pipe 4. The end cap 18 is then placed on the feeding hopper 5. The motor 9 is started, and the motor 9 drives the grinding roller 10 to rotate around the drive shaft 11 inside the grinding cylinder 3, against the inner wall of the grinding cylinder 3. Through the rotation of the grinding roller 10 and its cooperation with the grinding cylinder 3, the raw materials are ground. The ground particles are sieved through the sieve holes 6 at the bottom of the grinding cylinder 3. Particles that meet the size requirements fall through the sieve holes 6 to the bottom of the outer casing 1, while those that do not meet the size requirements... The grinding continues in the grinding cylinder 3. The ground powder falls to the bottom of the outer shell 1. The driven shaft 12 drives the stirring rod 13 to rotate through the transmission of the large synchronous pulley 14, the small synchronous pulley 15 and the synchronous belt 16. The stirring rod 13 stirs the powder through the stirring blades 17, so that the ground powder is dispersed. The diameter of the large synchronous pulley 14 is larger than that of the small synchronous pulley 15, so that the stirring blades 17 can stir the powder more quickly, avoiding the accumulation of lumps and making the powder evenly mixed. The grinding and dispersion of the raw materials can be observed through the observation window 20. After processing, the powder is discharged through the discharge pipe 7 by opening the discharge valve 8.

[0026] The grinding and dispersing equipment for paint production of this utility model has common mechanical installation, connection and setting methods, and can be implemented as long as it can achieve its beneficial effect. The discharge valve 8 and motor 9 of the grinding and dispersing equipment for paint production of this utility model are purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
