Detailed Implementation

[0027] like Figures 1 to 7 As shown, this utility model discloses a particle screening machine for preparing reclaimed rubber from waste tires. It includes a base 1, a vibrating motor 2, and a screening box 3. The vibrating motor 2 is mounted on the base 1. The screening box 3 is connected to the base 1 by a spring 4. A screen 5 is installed inside the screening box 3 to divide the box into several screening zones. A feed inlet 6 is located at the top of the screening box 3, and a discharge pipe 7 is provided. The number of discharge pipes 7 corresponds to the number of screening zones. The end of the screen 5 near the discharge pipe 7 is inclined downwards. Through this configuration, rubber powder can be screened, allowing it to enter different screening zones according to particle size, thus achieving powder sorting. Smaller particles are used for subsequent reclaimed rubber preparation, while larger particles are returned to the previous crushing and cutting process. Furthermore, the downward inclination of the screen 5 near the discharge pipe 7 facilitates the collection of rubber powder as it falls into the discharge pipe 7 from the screening zones.

[0028] As one implementation, the discharge pipe 7 is equipped with a closing mechanism to control its opening and closing. The closing mechanism includes a sealing plate 8 and a drive motor 9. The sealing plate 8 is rotatably connected to the screening box 3, and the drive motor 9 is connected to the sealing plate 8 and drives it to rotate. With this configuration, after screening is complete, the closing mechanism can be opened to allow the adhesive powder to enter the discharge pipe 7, while during screening, the opening and closing mechanism is closed to ensure the screening effect.

[0029] As one implementation method, the screen 5 and the screening box 3 are detachably connected. This design facilitates the replacement and cleaning of the screen 5, and allows for the use of screens with different mesh sizes depending on the reclaimed rubber preparation process.

[0030] Specifically, the screening box 3 is provided with a sliding groove 10, and the screen 5 is disposed in the sliding groove 10 and slidably connected to the sliding groove 10. The sliding groove 10 facilitates the disassembly and assembly of the screen 5, and also facilitates the positioning of the screen 5 in the screening box 3, making installation more convenient.

[0031] In this embodiment, the screen 5 is provided with a fixing block 11, and a locking block 12 is movably connected to the fixing block 11. The screening box 3 is provided with a locking groove 13, and the locking block 12 is locked in the locking groove 13. This arrangement facilitates the fixing of the screen 5, improves the connection and fixing effect between the screen 5 and the screening box 3, and the locking block 12 is movable, making it easier to release the fixing. The fixing block 11 is provided with a sliding groove 14, and the locking block 12 is located in the sliding groove 14 and slidably connected to the sliding groove 14. A compression spring 15 is provided in the sliding groove 14, and the compression spring 15 drives the locking block 12 to lock in the locking groove 13. This arrangement improves the fixing effect; the locking block 12 is locked in the locking groove 13 under the action of the compression spring 15, and it also prevents the locking block 12 from falling out of the locking groove 13 during vibration of the screening box 3, thus improving the reliability of the screening machine.

[0032] One end of the locking block 12 is provided with a guide part 16. The guide part 16 makes the installation of the screen 5 more convenient. Simply push the screen 5 into the screening box 3, and the locking block 12 will be locked into the slot 13, thereby fixing the screen 5.

[0033] As one implementation, the locking block 12 is provided with an extension piece 17, and the fixing block 11 is provided with a fixing piece 18. With the above arrangement, it is convenient to apply pressure to the extension piece 17 and the fixing piece 18, so that the extension piece 17 can move and drive the locking block 12 to move, thereby releasing the locking block 12 and facilitating the removal of the screen 5.

[0034] Specifically, both the fixing plate 18 and the extension plate 17 are provided with anti-slip textures 19. The anti-slip textures 19 make it easy for the user to apply force to the fixing plate 18 and the extension plate 17. The user can directly grasp the fixing edge and the extension plate 17 and press them together, so that the locking block 12 moves out of the fixing groove, and then the screen 5 can be pulled out laterally, making the removal of the screen 5 convenient and efficient.

[0035] As one implementation method, a gasket 20 is provided between the inner wall of the screening box 3 and the frame of the screen 5. The gasket 20 can fill the gap between the screening box 3 and the screen 5, and can prevent the screen 5 from touching the screening box 3 and making abnormal noise when the screening machine is working. The gasket 20 is generally made of rubber.

[0036] This invention enables the screening of rubber powder by setting a screen 5 inside the screening box 3. The rubber powder enters different screening zones according to particle size, thus achieving the sorting of rubber powder. The rubber powder with smaller particle size is used for subsequent reclaimed rubber preparation, while the rubber powder with larger particle size is returned to the previous process for crushing and cutting. Furthermore, the end of the screen 5 near the discharge pipe 7 is set downward to facilitate the rubber powder in the screening zone to fall into the discharge pipe 7, which is convenient for the collection of rubber powder.

[0037] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
