[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see ​In this embodiment of the invention, the multi-purpose stirring, milling, and dispersing machine for producing fluorescent powder includes a support frame 1. A screening mechanism 2 and a milling mechanism 3 are mounted on the support frame 1. The screening mechanism 2 includes a mounting plate 201, a filter screen 202, and a vibrating motor 203. The filter screen 202 is mounted in the middle of the mounting plate 201, and the vibrating motor 203 is fixedly mounted on the right end of the mounting plate 201. The screening mechanism 2 also includes a guide plate 204, a discharge hopper 205, and a conveying slope 206. A [missing information - likely a device or structure] is provided below the filter screen 202. A guide plate 204 is provided, a feeding hopper 205 is fixedly installed in the middle of the guide plate 204, a conveying slope 206 is fixedly installed at the lower end of the feeding hopper 205, the conveying slope 206 is located above the grinding chamber 304, a guide pipe 207 is fixedly installed at the left end of the mounting plate 201, a receiving platform 208 is provided below the guide pipe 207, a spring body 209 is fixedly installed at the lower end of the mounting plate 201, a support plate 210 is installed at the lower end of the spring body 209, and the support plate 210 is fixedly installed on the support frame 1.

[0034] The screening mechanism 2 adopts a vibrating bulk material structure and a material screening structure. Before use, different specifications of filter screens 202 can be selected according to the usage requirements. It is also necessary to connect the vibrating motor 203 to the power supply and the control terminal in advance. When starting, the fluorescent particles are first poured onto the filter screen 202. The vibrating motor 203 is started to drive the filter screen 202 to vibrate at high frequency. Under the action of vibration, most of the fluorescent particles of the same size will enter the grinding chamber 304 along the guide plate 204, the hopper 205 and the conveying slope 206. However, some of the larger fluorescent particles will be blocked on the filter screen 202 and enter the guide pipe 207 along the filter screen 202. To collect these fluorescent particles, a recycling bag needs to be placed on the receiving platform 208 in advance. The screening mechanism 2 can effectively filter the larger fluorescent particles, which prepares for the subsequent sand grinding mechanism 3 and prevents the larger fluorescent particles from entering the sand grinding mechanism 3 and clogging the grinding chamber 304. This ensures the stability and reliability of the operation and can also effectively remove the impurities present in the fluorescent particles.

[0035] The sanding mechanism 3 includes a mounting frame 303, a sanding chamber 304, a grinding disc 305, grinding grooves 306, protrusions 307, a first grinding disc 308, and a second grinding disc 309. The mounting frame 303 is fixedly installed at the lower end of the supporting frame 1. The sanding chamber 304 is fixedly installed on the mounting frame 303. The grinding disc 305 is located inside the sanding chamber 304. Protrusions 307 are fixedly installed on the outer wall of the grinding disc 305, and grinding grooves 306 are located on the outer side of the grinding disc 305. Multiple sets of grinding grooves 306 are distributed on the inner wall of the sanding chamber 304. The first grinding disc 308 is fixedly installed at the lower end of the grinding disc 305, and the second grinding disc 309 is fixedly installed at the lower end of the first grinding disc 308. The sanding mechanism 3 also includes a first transmission rod 310, an aluminum alloy bracket 312, and a hydraulic cylinder 313. The upper end of the grinding disc 305 is fixedly installed with... The system includes a first transmission rod 310, an aluminum alloy bracket 312 at its upper end, a hydraulic cylinder 313 fixedly mounted at the upper end of the aluminum alloy bracket 312, a support column 301 fixedly mounted at the right end of the support frame 1, a top plate 302 fixedly mounted at the upper end of the support column 301, the hydraulic cylinder 313 fixedly mounted on the top plate 302, a transmission disc 311 fixedly mounted on the first transmission rod 310, a transmission belt 317 on the outer side of the transmission disc 311, a drive disc 318 mounted at the right end of the transmission belt 317, a second transmission rod 316 fixedly mounted in the middle of the drive disc 318, a drive rod 315 inserted into the interior of the second transmission rod 316, a drive motor 314 fixedly mounted at the lower end of the support column 301, the transmission end of the drive motor 314 connected to the drive rod 315, and a connecting bearing between the aluminum alloy bracket 312 and the first transmission rod 310.

[0036] The grinding mechanism 3 adopts a multi-segment grinding structure and an adjustable grinding structure. The multi-segment grinding structure consists of a mounting frame 303, a grinding chamber 304, a grinding disc 305, a grinding groove 306, a protrusion 307, a first grinding disc 308, and a second grinding disc 309. The adjustable grinding structure consists of a support column 301, a top plate 302, a first transmission rod 310, an aluminum alloy bracket 312, and a hydraulic cylinder 313. Before use, the hydraulic cylinder 313 and the drive motor 314 need to be powered on and connected to the control terminal. The storage box needs to be placed under the grinding chamber 304 in advance. When in use, the grinding disc 305 can be adjusted through the adjustable grinding structure. 5. The positions of the first and second grinding discs 308 and 309 within the abrasive chamber 304 allow for adjustment of the particle size of the phosphor powder at the grinding point. If larger phosphor powder particles are required, the hydraulic cylinder 313 is activated to move the aluminum alloy support 312 from top to bottom, thereby moving the structures connected to the aluminum alloy support 312 (first transmission rod 310, transmission disc 311, grinding disc 305, first grinding disc 308, second grinding disc 309, second transmission rod 316, transmission belt 317, and drive disc 318), thereby adjusting the displacement of the grinding disc 305, the first grinding disc 308, and the second grinding disc 309. The size of the gap between the grinding chamber 304 and the wall of the grinding chamber; During grinding: the drive motor 314 drives the drive rod 315 to rotate. The drive rod 315 is inserted into the second transmission rod 316, which in turn drives the second transmission rod 316 and the drive disc 318 to rotate. At the same time, the drive disc 318 drives the transmission disc 311, the first transmission rod 310, and the lower crushing disc 305, the first crushing disc 308, and the second crushing disc 309 to rotate at high speed through the transmission belt 317. In this process, the crushing disc 305 squeezes the fluorescent particles. Under the crushing action of the crushing groove 306 and the protrusion 307, the fluorescent particles will be quickly broken, thus initially breaking the fluorescent particles. The light particles, followed by the fluorescent particles, reach the first grinding disc 308 and are crushed into powder there. The second grinding disc 309 further crushes the fluorescent powder. The final fluorescent powder is discharged from the grinding chamber 304 and collected by the storage box below. The grinding mechanism 3 grinds the fluorescent particles multiple times, which can quickly break the fluorescent particles and obtain fluorescent powder, achieving the effect of efficiently obtaining fine fluorescent powder. The adjustable grinding structure can adjust the size of the gap between the crushing disc 305, the first grinding disc 308, the second grinding disc 309 and the wall of the grinding chamber 304, so that fluorescent powder of different sizes can be obtained, achieving the control effect.

[0037] The working principle of this utility model is as follows: First, the fluorescent particle raw material is graded by the screening mechanism 2. The vibration motor 203 of the screening mechanism 2 (installed on the right end of the mounting plate 201) drives the filter screen 202 to vibrate at high frequency. Fluorescent particles that meet the volume requirements fall through the filter screen 202 into the guide plate 204, and are then transported to the grinding chamber 304 via the discharge hopper 205 and the conveying slope 206. Oversized particles and impurities slide down the guide pipe 207 on the left end of the mounting plate 201 into the recycling bag of the receiving platform 208, completing the screening. Subsequently, the grinding mechanism 3 is started: the hydraulic cylinder 313 adjusts the vertical position of the first transmission rod 310 through the aluminum alloy bracket 312, thereby linking the gap between the crushing turntable 305, the first grinding turntable 308, the second grinding turntable 309 and the inner wall of the grinding chamber 304. The drive motor 314 drives the second transmission rod 316 and the drive disc 318 to rotate via the drive rod 315. The transmission disc 311 is linked by the transmission belt 317, which drives the granulation turntable 305 to rotate at high speed. The fluorescent particles are initially crushed between the protrusions 307 of the granulation turntable 305 and the granulation grooves 306 on the inner wall of the grinding chamber 304. They are then crushed into powder by the first grinding turntable 308 and further refined by the second grinding turntable 309. The final product is discharged from the bottom of the grinding chamber 304. Throughout the process, the elastic support system formed by the spring body 209 and the support plate 210 ensures the stable vibration of the screening mechanism 2. The conveying slope 206 and the guide pipe 207 form a directional flow path. The support column 301 and the top plate 302 provide rigid support for the hydraulic cylinder 313. The multi-stage transmission structure realizes efficient power transmission.

[0038] 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.
