[0019] The specific settings and functions of this embodiment are described below. The stabilizing platform 1 serves as the equipment base, providing stable support for the whole. The support frame 11 is vertically fixed to the upper end of the stabilizing platform 1, bearing the first crushing mechanism 12 and providing installation space for the screening mechanism 3. The two are connected by high-strength welding or bolts to ensure the stability of equipment operation. Primary crushing: The first crushing mechanism 12 is integrated on the upper end of the support frame plate 11. It performs preliminary crushing of the powder coating through a high-speed rotating component. The crushed material is then transported to the screening mechanism 3 through the lower hose. Secondary crushing: The second crushing mechanism 2 is fixed on the upper end of the stabilizing platform 1 and consists of a fixed frame 21, a power system 22, a grinding box 23, a grinding disc 24, a grinding seat 25, a discharge seat 27, and a feed hopper 26. The power system 22 is installed on the upper end of the fixed frame 21, and its transmission end passes through the grinding box 23 and is connected to the grinding disc 24, which facilitates driving the grinding disc 24 to rotate at high speed in the center of the grinding seat 25 to achieve fine grinding. The lower end of the grinding box 23 is fixed to the discharge seat 27, and the feed hopper 26 connects the external raw materials to the feed end of the grinding box 23 to form a complete crushing path.
[0020] Example 2: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the screening mechanism 3 includes a support base 31, a placement support plate 32 fixedly installed on the upper end of the grinding box 23, an elastic component 321 fixedly installed on the upper end of the placement support plate 32, a screening box 33 fixedly installed on the upper end of the movable end of the elastic component 321, a folded tube 34 fixedly installed at the lower opening of the screening box 33, a discharge box 38 fixedly installed at one end opening of the screening box 33, a vibration motor 36 fixedly installed at the other end of the screening box 33, an inclined screen 310 fixedly installed inside the screening box 33, and a pump body 37 fixedly installed on the upper end of the support base 31. A shaped tube 35 is fixedly installed at the upper discharge port of the pump body 37, a connecting pipe 39 is fixedly installed at the feed end of the pump body 37, one end of the support base 31 is fixed to one end of the support frame plate 11, the lower end of the support plate 32 is fixed to the upper end of the stable platform 1, the lower end of the folded tube 34 is fixed to the upper end of the feed hopper 26, the feed end of the connecting pipe 39 is fixed to the discharge end of the lower end of the discharge box 38, the discharge port of the shaped tube 35 is located directly above the first crushing mechanism 12, a flexible hose is installed at the lower end of the first crushing mechanism 12, and the lower end of the flexible hose is fixed to the upper opening of the screening box 33.
[0021] The overall effect of the embodiment is as follows: Dynamic screening module: The screening mechanism 3 is embedded in the support frame plate 11, with the vibration motor 36 as the power source. The screening box 33 is suspended on the placement support plate 32 through the elastic component 321. The internal inclined screen 310 vibrates at high frequency under the drive of the vibration motor 36 to achieve precise screening. Qualified materials enter the grinding box 23 for secondary crushing through the folded tube 34. Unqualified coarse powder is transported to the special-shaped tube 35 by the pump body 37 through the discharge box 38 and the connecting pipe 39, and then sent back to the first crushing mechanism 12 for recycling. The circulating transmission module consists of a closed-loop transmission system composed of a folded pipe 34, a special-shaped pipe 35, a connecting pipe 39, and a flexible hose. Each pipeline is connected by a quick-connect flange or a sealing buckle. Combined with the pressure delivery of the pump body 37, it ensures the leak-free and efficient flow of powder coatings between the crushing and screening stages. The elastic component 321 can effectively absorb the impact force generated by the vibration motor 36 and reduce the risk of equipment resonance; the support base 31 can provide a support point for the pump body 37 and improve the stable operation of the pump body 37.
[0022] The usage and working principle of this device: Before starting the equipment, the powder coating raw material is first sent to the top of the first crushing mechanism 12 via an external conveying device, ready to enter the crushing process. When the powder coating enters the first crushing stage of the dual-stage crushing module, the high-speed rotating parts (such as crushing blades) in the first crushing mechanism 12 rotate at high speed under the drive of the motor to initially crush the input powder coating. Through the impact and shearing action of the high-speed rotating parts, the larger particles of raw material are crushed into smaller particles. The material after initial crushing is conveyed to the screening box 33 of the dynamic screening module through the hose at the lower end of the first crushing mechanism 12. Then, the material enters the screening box 33, the dynamic screening mechanism 3 starts to function, the vibration motor 36 is powered on and starts to generate high-frequency vibration, this vibration drives the screen 310 to vibrate together through the screening box 33. Under the action of vibration, the screen 310, which is inclined inside the screening box 33, causes the material entering the screening box 33 to move continuously on the screen 310. Fine powder coating particles that meet the particle size requirements pass through the screen 310 and fall into the bottom of the screening box 33. Then, they are conveyed to the feed hopper 26 of the second crushing mechanism 2 through the folding pipe 34 and enter the secondary crushing stage. Larger particles and coarse powder that do not pass through the screen 310 slide along the inclined screen 310 towards the discharge box 38, and finally enter the pump body 37 through the discharge box 38 and the connecting pipe 39. Afterwards, once the pump body 37 is started, the coarse powder is conveyed back to the top of the first crushing mechanism 12 through the shaped tube 35, so that it re-enters the first-stage crushing process, thereby realizing the recycling and crushing of unqualified materials. Finally, the material entering the secondary crushing stage enters the grinding box 23 through the feed hopper 26. At this time, the second crushing mechanism 2 of the dual-stage crushing module starts to work. The power system 22 on the fixed frame 21 is powered on, and its transmission end drives the grinding disc 24 to rotate at high speed in the center of the grinding seat 25. A grinding space is formed between the grinding disc 24 and the grinding seat 25. The powder coating is subjected to compression, grinding, friction and other effects between the two, and is further crushed into finer and more uniform particles. After grinding, the powder coating is discharged from the equipment through the discharge seat 27 connected to the lower end of the grinding box 23, completing the entire crushing and screening process.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
