Description
Technical Field
[0001] This utility model relates to the field of putty production, and more specifically, it relates to a particle grading and screening device for putty production. Background Technology
[0002] Putty powder is commonly used in construction and interior decoration. Applying putty to walls or floors facilitates decoration and painting, greatly contributing to the long-term use of buildings. During putty powder production, various raw materials are often mixed. However, due to prolonged storage or environmental factors, powdered materials can clump together into granules, and these granules can also become larger, affecting production. Therefore, screening devices are needed to separate the raw materials. Existing screening processes often use sieves to separate particle sizes, but this only addresses particle size and cannot change the size of unsuitable particles. Therefore, other devices are needed to recycle the screened particles. Furthermore, after screening, it's inconvenient to obtain materials of different particle sizes, thus affecting the overall usability of the screening device. Utility Model Content

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a particle grading and screening device for putty production, which has the following beneficial effects: 1. This utility model, by setting a screening structure, allows for the selection of filling blocks that meet the screening requirements when screening raw materials. The filling blocks are installed in the placement holes opened on the screening holes through the cooperation of the matching blocks and notches, thereby facilitating the change of the diameter of the screening holes on the screening plate, and thus facilitating the adjustment of the screening plate as needed, thereby facilitating the use of the entire screening plate.
[0012] 2. This utility model uses cutting blocks on a screening plate. The cutting blocks are installed on the screening plate by engaging the mounting posts with the mounting holes. When the raw material falls onto the screening plate, the raw material particles come into contact with the cutting blocks. The raw material is affected by the speed and gravity of entering the main body box and is cut by the sharp part of the cutting blocks, thereby reducing the volume of the raw material particles. This makes it easier for the raw material to pass through multiple screening structures and become particles of the required diameter, thus facilitating the use of the raw material particles.

The screening plate screens the particles of the raw materials by size, and the raw materials that can pass through the screening holes fall onto the guide plate. Through the inclination of the guide plate and the cooperation of the discharge port, the raw materials slide down through the discharge port and enter the first collection box. This achieves screening of raw materials with different particle diameters and facilitates the acquisition of the screened raw materials, making the entire screening device easy to use.

[0021] More specifically, the screening structure enables the screening of raw material particles, and the collection structure facilitates the collection of the screened raw materials.
[0022] Please see Figures 1-5As one implementation of the entire device: a baffle 9 is detachably installed on the main body box 1, and a first connecting block 10 is fixedly installed at both ends of the baffle 9. A first connecting groove 11 is opened on the main body box 1, and the first connecting block 10 and the first connecting groove 11 cooperate with each other. An installation block 12 and a support block 13 are fixedly installed inside the main body box 1. Multiple installation blocks 12 are provided. A second connecting block 14 is provided on the side end of the screening plate 4. A second connecting groove 15 is opened on the installation block 12. The support block 13 cooperates with the guide plate 5. The second connecting block 14 and the second connecting groove 15 cooperate with each other. A placement hole 16 is opened on the screening plate 4, and multiple placement holes 16 are provided. A filling block 17 is installed in the placement hole 16, and a screening hole 18 is opened on the filling block 17. A notch is opened on the side end of the screening plate 4 located at the placement hole 16. 19. Multiple slots 19 are provided. A mating block 20 is fixedly provided on the side end of the filling block 17. The mating block 20 and the slot 19 are mutually mated. A cutting block 21 is detachably provided on the screening plate 4. Multiple cutting blocks 21 are provided. An installation column 22 is fixedly provided on the screening plate 4. An installation hole 23 is fixedly provided at the lower end of the cutting block 21. The installation column 22 and the installation hole 23 are mutually mated. The installation column 22 and the installation hole 23 are engaged and connected. A second collection box 24 is provided inside the main body box 1. Multiple support plates 7 and first collection boxes 8 are provided. The support plate 7 is provided on the main body box 1 and located at the lower end of the discharge port 6. The first collection box 8 is detachably provided on the support plate 7. The first collection box 8 and the discharge port 6 are mutually mated. Limiting blocks 25 are provided at both ends of the support plate 7. The limiting blocks 25 are fixedly connected to the support plate 7. Specifically, when screening raw materials, a filler block 17 matching the screening hole 18 is selected according to the screening requirements. The filler block 17 is installed in the placement hole 16 on the screening hole 18 through the cooperation of the mating block 20 and the notch 19. This facilitates changing the diameter of the screening hole 18 on the screening plate 4, allowing for adjustment of the screening plate 4 as needed. When raw materials fall onto the screening plate 4, the raw material particles come into contact with the cutting block 21. Affected by the speed and gravity of the material entering the main body box 1, the raw material is cut by the sharp part of the cutting block 21. This reduces the volume of raw material particles, making it easier for the raw material to pass through multiple screening structures and become particles of the required diameter. When screening the raw material, the raw material is poured into the main body box 1 from the feed hood 3. The particle size of the raw material is screened by the screening plate 4. The raw material that can pass through the screening hole 18 falls onto the guide plate 5. Through the inclination of the guide plate 5 and the cooperation of the discharge port 6, the raw material slides down through the discharge port 6 and enters the first collection box 8, thereby realizing the screening of raw materials of different particle diameters and facilitating the acquisition of the screened raw materials.
[0023] In summary, when using it as a whole: When screening raw materials, according to the screening requirements, a filler block 17 that meets the requirements of the screening hole 18 is selected. The filler block 17 is installed in the placement hole 16 opened on the screening hole 18 by the cooperation of the mating block 20 and the notch 19, so as to facilitate changing the diameter of the screening hole 18 on the screening plate 4, and thus facilitate adjusting the screening plate 4 as needed.
[0024] When the raw material falls onto the screening plate 4, the raw material particles come into contact with the cutting block 21. The raw material is affected by the speed and gravity of entering the main body box 1 and is cut by the sharp part of the cutting block 21, thereby reducing the volume of the raw material particles. This makes it easier for the raw material to pass through multiple screening structures and become particles of the required diameter.
[0025] When screening raw materials, the raw materials are poured into the main body box 1 from the feed hood 3. The particle size of the raw materials is screened by the screening plate 4. The raw materials that can pass through the screening holes 18 fall onto the guide plate 5. Through the inclination of the guide plate 5 and the cooperation of the discharge port 6, the raw materials slide down and enter the first collection box 8 through the discharge port 6. This achieves screening of raw materials with different particle diameters and facilitates the acquisition of the screened raw materials.
