[0002] In recent years, my country's coatings industry has developed rapidly. With the improvement of environmental protection regulations and the awakening of consumers' environmental awareness, the coatings market is trending towards healthier and safer products. The continuous promotion of low-carbon and environmentally friendly concepts throughout society has led to the emergence of polymer water-based coatings, which, due to their superior environmental performance, are increasingly replacing solvent-based coatings. Their growth rate has consistently exceeded the industry average. It is expected that with further improvements in environmental standards, polymer water-based coatings will become an inevitable trend in the future development of the coatings industry, and the rate of increase in their market share will accelerate. As a processing industry, grinding polymer water-based coatings is an essential and crucial step in their production.

[0003] Current polymer water-based coating raw material grinding equipment typically grinds raw materials by using a single grinding disc in conjunction with a grinding tank. However, it is not easy to pre-crush larger raw materials before grinding, which affects the grinding effect, reduces grinding efficiency, and diminishes the practicality of the equipment. Utility Model Content

Detailed Implementation

[0028] Please see Figure 1 This application provides a grinding device for polymer water-based coating raw materials, including a grinding structure 10 and a crushing structure 20.

[0029] Please see Figure 1 , Figure 2 and Figure 4 The grinding structure 10 includes a housing 110 and a grinding assembly 120, with the grinding assembly 120 disposed inside the housing 110.

[0030] In a specific configuration, the grinding assembly 120 includes a motor 121, a rotating shaft 122, a grinding disc 123, and a grinding tank 124. The motor 121 is mounted on one side of the housing 110. The rotating shaft 122 is fixedly connected to the output end of the motor 121 and rotatably connected to the housing 110. The grinding disc 123 is fixedly connected to the rotating shaft 122. The grinding tank 124 is fixedly connected to the inner wall of the housing 110, and the grinding disc 123 is disposed within the grinding tank 124. The arrangement of the motor 121, rotating shaft 122, grinding disc 123, and grinding tank 124 facilitates the grinding of polymer water-based coating raw materials.

[0031] In the specific configuration, feeding hoppers 130 are provided on both sides of the housing 110. The feeding hoppers 130 are connected to the crushing tank 230. The connection between the feeding hoppers 130 and the crushing tank 230 facilitates feeding.

[0032] In a specific configuration, a collection frame 140 is slidably connected to the bottom of the housing 110. By slidably connecting the collection frame 140 to the bottom of the housing 110, the ground raw materials can be easily collected.

[0033] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The crushing structure 20 includes a drive assembly 210, a crushing block 220, a crushing trough 230, and a feeding assembly 240. The drive assembly 210 is disposed inside the housing 110. The crushing block 220 is connected to the drive assembly 210. The housing 110 has a crushing trough 230. The crushing block 220 is slidably connected to the crushing trough 230. The feeding assembly 240 is disposed inside the housing 110 and fits against the crushing trough 230.

[0034] In its specific configuration, the drive assembly 210 includes a horizontal plate 211, two U-shaped support blocks 212, rollers 213, an inclined block 214, a lifting plate 215, a connecting block 216, a slide rod 217, a fixing block 218, and a spring 219. The horizontal plate 211 is fixedly connected to the outer ring of the rotating shaft 122. The two U-shaped support blocks 212 are positioned opposite each other on one side of the horizontal plate 211, and rollers 213 are rotatably connected inside each of the two U-shaped support blocks 212. The inclined block 214 is fixedly connected to the lifting plate 215, and the rollers 213 and the inclined block 214 are intermittently in contact. A connecting block 216 is fixedly connected to one side of the lifting plate 215. The crushing block 220 is connected to the connecting block 216. Block 216 is fixedly connected, slide rod 217 is fixedly connected to lifting plate 215, slide rod 217 is slidably connected to box 110, fixed block 218 is fixedly connected to one end of slide rod 217, and spring 219 is fixedly connected to fixed block 218 and box 110 at both ends respectively. In this way, through the setting of horizontal plate 211, two U-shaped support blocks 212, roller 213, inclined block 214, lifting plate 215, connecting block 216, slide rod 217, fixed block 218 and spring 219, it is convenient to grind the grinding component 120 while simultaneously crushing the larger raw materials in the crushing tank 230 with the crushing block 220, which facilitates the initial crushing.

[0035] In a specific configuration, the feeding assembly 240 includes two electric push rods 241 and a U-shaped slide plate 242. The two electric push rods 241 are installed on one side of the housing 110. The U-shaped slide plate 242 is fixedly connected to the movable ends of the two electric push rods 241 and is slidably connected to the housing 110. The U-shaped slide plate 242 is in contact with the crushing tank 230. The arrangement of the two electric push rods 241 and the U-shaped slide plate 242 facilitates the initial crushing of the raw materials into the grinding tank 124 for feeding.

[0036] In the specific configuration, the U-shaped slide plate 242 is provided with a through groove 250, and the lifting plate 215 is set in the through groove 250. By setting the lifting plate 215 in the through groove 250, it is possible to avoid the mutual interference between the movement of the lifting plate 215 and the U-shaped slide plate 242.

[0037] In the specific configuration, both the bottom of the crushing block 220 and the crushing tank 230 are provided with inclined surfaces. By providing inclined surfaces at the bottom of both the crushing block 220 and the crushing tank 230, the raw materials after preliminary crushing can easily fall into the grinding tank 124 through the inclined surfaces.

[0038] The working principle of the polymer water-based coating raw material grinding device is as follows: When using the polymer water-based coating raw material grinding device, the raw material enters the crushing tank 230 through the feed hoppers 130 on both sides. The motor 121 drives the rotating shaft 122 to rotate the grinding disc 123 for grinding. At the same time, the horizontal plate 211 on the outer ring of the rotating shaft 122 rotates, causing the rollers 213 on the U-shaped support block 212 to intermittently lift the inclined block 214. The inclined block 214 drives the lifting plate 215 to move upward and stretch the spring 219. When the rollers 213 disengage from the inclined block 214, the spring 219 resets and drives the slide rod 217 to drive the lifting plate 215 to rush downward. Through the connecting block 216, the crushed block 220 impacts the material. After the raw material in the crushing tank 230 is initially crushed, the electric push rod 241 pushes the U-shaped slide plate 242 to rise and open the feeding channel. The crushed raw material slides down the inclined surface at the bottom of the crushing tank 230 and falls into the grinding tank 124. The electric push rod 241 retracts and the U-shaped slide plate 242 closes the feeding channel. The feed hopper 130 continues to replenish the raw material. After the grinding disc 123 rotates in the grinding tank 124 to complete fine grinding, the drive component 210 continuously realizes the reciprocating impact of the crushed block 220 through the linkage of the roller 213, the inclined block 214 and the spring 219. Finally, the ground product is collected and recycled through the collection frame 140 slidably connected to the bottom of the box 110.

[0039] It should be noted that the specific model and specifications of motor 121 and electric push rod 241 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0040] The power supply and operating principle of the motor 121 and the electric push rod 241 are clear to those skilled in the art and will not be described in detail here.

[0041] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
