[0001] This utility model relates to the field of grinding equipment technology, specifically to a grinding equipment for preparing breathable powder coatings. Background Technology

[0002] Powder coatings are solid powdered synthetic resin coatings composed of solid resins, pigments, fillers, and additives. Unlike ordinary solvent-based and water-based coatings, their dispersion medium is not solvents and water, but air. They are characterized by no solvent pollution, 100% film formation, and low energy consumption. Powder coatings are divided into two main categories: thermoplastic and thermosetting.

[0003] According to the patent publication number CN 212681166 U, a grinding device for preparing powder coatings with super strong adhesion is disclosed. This device adopts a dual grinding mechanism, which can grind different coating powders at the same time. It has high grinding quality, reduces working costs, facilitates material feeding and unloading, and has high processing efficiency, which further makes grinding technology more practical and is conducive to the promotion and application of grinding technology. However, when the device screens materials through a screen, the screen is fixed, which affects the screening effect of the screen.

[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 1-4 As shown, this utility model provides a technical solution: a grinding device for preparing breathable powder coatings, including a machine body 1, a grinding tank 2 opened on the side of the machine body 1, a door 4 set on the side of the machine body 1, a motor 5 fixedly installed on the side of the machine body 1 via a base, a partition 6 fixedly installed inside the machine body 1, and a connecting assembly 3 set inside the machine body 1. The connecting assembly 3 includes a grinding mechanism 31 set on the side of the machine body 1. A disassembly and assembly mechanism 32 is set inside the machine body 1. A discharge port is opened at the bottom of the inner wall of the grinding tank 2. A collection box is set inside the machine body 1. The grinding mechanism 31 includes a first rotating shaft 311 rotatably connected to the inside of the machine body 1 via a bearing. A grinding roller 312 is fixedly connected to the outer wall of the first rotating shaft 311. A drive wheel 313 is fixedly connected to the outer end of the machine body 1. A transmission belt 314 is rotatably connected to the drive wheel 313. A mounting bracket 315 is fixedly connected to the side wall of the machine body 1. A second rotating shaft 316 is rotatably connected to the inside of the mounting bracket 315 through a bearing. A pressing rod 317 is fixedly connected to the inner end of the second rotating shaft 316 through a rotating rod. A ball bearing is provided at the end of the pressing rod 317. A driven wheel 318 is fixedly connected to the outer wall of the second rotating shaft 316. A mounting column 319 is movably connected inside the machine body 1. An inclined pressing ring 3110 is fixedly installed at the outer end of the mounting column 319 through a mounting seat. A connecting column 3111 is movably connected inside the machine body 1. A limit block 3112 is fixedly connected to the outer end of the connecting column 3111. A first spring 3113 is fixedly connected to the inner side of the limit block 3112.

[0029] In this embodiment, the end of the first rotating shaft 311 away from the driving wheel 313 is fixedly connected to the output end of the motor 5, and the transmission belt 314 is rotatably connected to the driven wheel 318. Through the cooperation of the first rotating shaft 311, grinding roller 312, driving wheel 313, transmission belt 314, mounting bracket 315, second rotating shaft 316, pressing rod 317, driven wheel 318, mounting column 319, inclined pressing ring 3110, connecting column 3111, limiting block 3112, and first spring 3113, the ground powder coating can be vibrated and screened, which can prevent the screen fixedly installed inside the screening frame 323 from clogging, and at the same time improve the screening effect, thereby improving the quality of the coating powder.

[0030] Furthermore, the end of the first spring 3113 away from the limiting block 3112 is fixedly connected to the outer wall of the body 1, and the inner end of the connecting column 3111 is fixedly connected to the mounting frame 321.

[0031] In use, the permeable powder coating material is first placed manually into the grinding tank 2. Then, the motor 5 drives the first rotating shaft 311 to rotate, which in turn rotates the grinding roller 312 fixedly connected to the outer wall of the first rotating shaft 311, thus grinding the material. The ground material then falls into the screening frame 323 through the discharge port and is then screened by the screen fixedly installed inside the screening frame 323. When the first rotating shaft 311 rotates, the second rotating shaft 316 rotates synchronously under the action of the driving wheel 313, the transmission belt 314, and the driven wheel 318. This allows the ball bearings at one end of the pressure rod 317 to slide relative to the inclined pressure ring 3110. Subsequently, under the action of the mounting column 319, the mounting frame 321 can slide relative to the machine body 1. At the same time, under the action of the connecting column 3111, the limiting block 3112, and the first spring 3113, the mounting frame 321 can reciprocate within the machine body 1, thereby causing the screening frame 323 to move synchronously. This allows the screen to vibrate and screen the material, resulting in better screening and improved quality of the coating powder. Furthermore, this device can perform grinding and processing operations on different types of powder coatings, thus increasing the applicability of the device.

[0032] Example 2

[0033] Based on Example 1, a preferred embodiment of the grinding equipment for preparing breathable powder coatings provided by this utility model is as follows: Figures 1 to 4 As shown: The disassembly and assembly mechanism 32 includes an assembly frame 321 fixedly installed inside the mounting column 319. An assembly groove 322 is provided inside the assembly frame 321. A screening frame 323 is inserted into the mounting groove 322. A screening mesh is fixedly installed inside the screening frame 323. A slot 324 is provided on the upper part of the screening frame 323. A movable groove 325 is provided inside the assembly frame 321. A movable block 326 is slidably connected to the inner wall of the movable groove 325. An inclined pressing block 327 is fixedly connected to the lower part of the movable block 326. A connecting rod 328 is fixedly connected to the upper part of the movable block 326. A second spring 329 is fixedly connected to the inner wall of the movable groove 325. A pull rod is fixedly connected to the top of the connecting rod 328 through the connecting block.

[0034] In this embodiment, one end of the second spring 329 is fixedly connected to the movable block 326, and the inclined pressing block 327 is movably inserted through the movable groove 325. The inclined pressing block 327 is engaged with the slot 324. Through the cooperation of the mounting frame 321, mounting groove 322, screening frame 323, slot 324, movable groove 325, movable block 326, inclined pressing block 327, connecting rod 328, and second spring 329, it is convenient for manual disassembly of the screening frame 323, thereby facilitating manual cleaning of the screen fixedly installed inside the screening frame 323, preventing screen blockage and affecting subsequent use.

[0035] Furthermore, the top of the connecting rod 328 extends through the movable slot 325.

[0036] When the screening frame 323 needs to be disassembled, simply hold the lever and pull the connecting rod 328 upwards. This will cause the movable block 326, which is fixedly connected to the bottom of the connecting rod 328, to move the inclined pressing block 327 upwards, thereby separating the inclined pressing block 327 from the slot 324. Then, the screening frame 323 can be pulled out, making it easier for manual cleaning of the screen fixedly installed inside the screening frame 323. This prevents the screen from becoming clogged and affecting subsequent use.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
