Description

Technical Field

[0001] This utility model relates to the technical field of grinding tools for water-based paint raw materials, and in particular to a grinding device for water-based paint raw materials with a uniform mixing and discharging structure. Background Technology

[0002] Water-based paint raw materials contain a variety of components, such as resins, pigments, and additives. These components differ in physical and chemical properties, such as pigment particle size and density, and resin viscosity. If they are not mixed evenly during processing, it will lead to unstable product quality. For example, uneven pigment distribution may result in inconsistent color of the water-based paint after application, or problems with the coating's hiding power, gloss, and other properties.

[0003] Existing mixing components mostly use containers and stirring plates to mix materials. However, due to the presence of stirring gaps between the container and the stirring plate, some small particles in these gaps will re-agglomerate during mixing. These agglomerated particles will affect the normal operation of the feed hopper. The feed hopper is easily blocked by these agglomerated particles. Once blocked, the material cannot enter the feed hopper stably for grinding. This not only interrupts the production process but also requires additional manpower and time to clean the feed hopper, seriously affecting production efficiency. Therefore, this application designs a water-based paint raw material grinding device with a uniform mixing and discharge structure to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water-based paint raw material grinding device with a uniform mixing and discharge structure.

[0006] Preferably, the side end of the crushing box is provided with a support frame, the support frame is mounted with a first motor box, two twisting crushing rollers are arranged laterally in the crushing box, the side end of each twisting crushing roller is provided with a gear for meshing transmission, and one of the twisting crushing rollers is coaxially fixed to the output shaft extending from the first motor box.

[0007] Preferably, a rotary motor is installed in the mixing drum, and a connecting rod is coaxially fixed to the connecting shaft of the rotary motor, with a mixing plate provided on the connecting rod.

[0008] Preferably, the screening and conveying assembly consists of an electric conveyor belt installed at an incline below the mixing drum and a limiting impact plate on the side of the electric conveyor belt. The limiting impact plate is installed at an incline below the mixing drum, and the bottom end of the limiting impact plate abuts against the electric conveyor belt.

[0009] Preferably, the grinding assembly consists of a grinding block and a mating grinding block, with a grinding gap between the grinding block and the mating grinding block. The upper middle part of the grinding block is provided with a feed hopper leading to the grinding gap, and the lower end of the grinding block is provided with a second motor for driving the grinding block to rotate.

[0010] Preferably, a discharge guide rail is provided on the limiting baffle wall at the side end of the grinding block, and a collection box is provided at the end of the discharge guide rail.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, the material can be crushed by the combination of the crushing box and the mixing drum, and the material is mixed and stirred by the mixing plate in the mixing drum, realizing the function of uniform material mixing and discharge. Then, the limiting impact plate and the screening discharge of the electric conveyor belt facilitate the removal of particles that have been re-formed in the mixing device, thereby realizing the function of screening before grinding, thus reducing the impact of easy blockage of the feed hopper. The impact of the limiting impact plate on the discharged material breaks up the large particle structure that has been formed, so that the material can enter the feed hopper stably for grinding. Finally, it solves the problem that some small particle structures are re-formed during the mixing of existing mixing components, which reduces the grinding efficiency of the grinding device.

[0019] Example: See Figure 1-4 This utility model discloses a water-based paint raw material grinding device with a uniform mixing and discharge structure, comprising a grinding box 1, a grinding assembly inside the grinding box 1, a screening and conveying assembly 6 inclined at the upper end of the grinding assembly, a mixing and stirring drum 5 installed at the upper end of the grinding box 1, and a crushing box 2 installed at the upper end of the mixing and stirring drum 5. The arrangement of the grinding box 1 and the crushing box 2 allows for better crushing and mixing of the water-based paint raw materials, with the grinding box 1 performing the grinding and mixing process. A support frame is provided on the side of the crushing box 2, and a first motor housing 4 is installed on the support frame. Two twisting crushing rollers 3 are arranged laterally at intervals in the crushing box 2. Each twisting crushing roller 3 has a meshing gear on its side end. One twisting crushing roller 3 is coaxially fixed to the output shaft extending from the first motor housing 4. The twisting crushing rollers 3 enable the twisting and crushing of large, compacted water-based paint raw materials. A rotary motor is installed in the mixing drum 5. A connecting rod is coaxially fixed to the connecting shaft of the rotary motor. A mixing plate 9 is installed on the connecting rod. The mixing plate 9 can disperse the water-based paint raw materials crushed by the crushing box 2, so that the added water-based paint raw materials can be mixed. The rotary motor is model Y80M1-2. The screening and conveying assembly 6 consists of an electric conveyor belt installed at an incline below the mixing drum 5 and a limiting impact plate 10 on the side of the electric conveyor belt. The limiting impact plate 10 is installed at an incline below the mixing drum 5, and the bottom end of the limiting impact plate 10 abuts against the electric conveyor belt. Through the setting of the limiting impact plate 10 and the electric conveyor belt, the particles of water-based paint raw materials can be further screened. After the large water-based paint raw material particles are transported, they collide with the limiting impact plate 10 to reduce the size of the water-based paint raw material particles, thereby being transported by the electric conveyor belt.

[0020] In this utility model, the grinding assembly consists of a grinding block 8 and a mating grinding block 11. A grinding gap exists between the grinding block 8 and the mating grinding block 11. The upper middle part of the grinding block 8 is provided with a feed hopper 7 leading to the grinding gap. The lower end of the mating grinding block 11 is provided with a second motor 12 for driving the mating grinding block 11 to rotate. Through the arrangement of the grinding block 8 and the mating grinding block 11, the introduced water-based paint raw material particles can be moved and ground from the bottom of the feed hopper 7 to the side of the bottom surface of the grinding block 8. A discharge guide rail 13 is provided on the limiting baffle wall at the side end of the grinding block 8. A collection box 14 is provided at the end of the discharge guide rail 13. Through the arrangement of the discharge guide rail 13 and the collection box 14, the ground water-based paint raw material can be collected better.

[0021] Working Principle: In the use of this utility model, firstly, a motor is installed in the motor box and transmission assembly. Then, the motor is connected to the power supply through wires, and an electric control valve for material discharge control is installed at the bottom of the mixing drum 5. Subsequently, different water-based paint raw materials are poured into the crushing box 2. The large lumps in the water-based paint raw materials are crushed by the rotation of the twisting crushing roller 3. Then, the crushed material enters the mixing drum 5 for mixing. Then, the electric control valve is opened to send the mixed material to the electric conveyor belt. The setting of the limiting impact plate 10 and the electric conveyor belt can further screen the particles of the water-based paint raw materials. After the large water-based paint raw material particles are transported, they collide with the limiting impact plate 10 to reduce the size of the water-based paint raw material particles. Then, through the transmission of the electric conveyor belt, the material is finally sent to the grinding assembly. The setting of the grinding block 8 and the matching grinding block 11 can move the poured water-based paint raw material particles from the bottom of the feed hopper 7 to the side of the bottom surface of the grinding block 8 for grinding. Then, it is sent to the collection box 14 for collection. The use of the device ends here.
