[0025] 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.

[0026] Please see Figure 1-7 This utility model provides a technical solution: a grinding device, including a mounting platform 1, a grinding box 3 disposed on the upper end of the mounting platform 1, a feed hopper 4 disposed on the upper end of the grinding box 3 and communicating with the grinding box 3, and a discharge frame 5 disposed on the lower end of the grinding box 3 and communicating with the grinding box 3. A bracket 11 is fixed to the lower end of the mounting platform 1, and the device also includes:

[0027] The grinding device 2 is set at the top of the mounting platform 1 and passes through the inside of the grinding box 3, and is used to crush the insulation board raw material.

[0028] Filter screen 25 is installed inside the grinding box 3; it is used to filter the raw materials of the insulation board.

[0029] The cleaning device 6 is located on one side of the grinding box 3 and below the filter screen 25, and is used to clean the filter screen 25.

[0030] It should be noted that during operation, the raw materials for producing insulation boards are added from the feed hopper 4 into the grinding chamber 3. Then, the power unit on the grinding device 2 is started to crush the raw materials inside the grinding chamber 3. After crushing, powder of qualified particle size falls from the filter screen 25 and is discharged from the discharge frame 5. After the device has been used for a period of time, the filter screen 25 needs to be cleaned. At this time, the cleaning device 6 is pulled to clean the filter screen 25. Through the grinding device 2, a high-efficiency and uniform crushing effect can be achieved. By controlling the movement of the cleaning device 6 at the lower end of the filter screen 25, the powder clogging the filter screen 25 can be easily removed, avoiding frequent shutdowns for cleaning, greatly improving production efficiency, and avoiding direct contact between personnel and the high temperature or sharp parts inside the grinding chamber 3, thus improving production safety.

[0031] In one embodiment, the grinding device 2 includes a motor 21 fixed on the upper end of the mounting platform 1, a rotating shaft 22 disposed at the power output end of the motor 21 and passing through the inside of the grinding box 3, and a pulverizing component 24 disposed on the rotating shaft 22. A connecting component 23 is disposed on one side of the grinding box 3 and is connected to the rotating shaft 22.

[0032] This design is for reference. Figure 2-6 The motor 21 serves as the power source, driving the rotating shaft 22 to drive the connecting part 23 to move, thereby enabling the crushing part 24 to crush the insulation material raw material inside the grinding box 3. The crushing part 24 is set on the rotating shaft 22 and moves at high speed with the rotation of the rotating shaft 22, efficiently crushing the insulation board raw material, and ensuring that the crushed powder has a uniform particle size, which meets the requirements of subsequent processing and use.

[0033] In one embodiment, the connector 23 includes a drive gear 231 fixed on the rotating shaft 22, a connecting shaft 232 passing through the grinding box 3, and a driven gear 233 sleeved on the connecting shaft 232. The drive gear 231 and the driven gear 233 are meshed and connected. The grinding box 3 is provided with a protective box 32 for protecting the connector 23.

[0034] This design is for reference. Figure 4-6 The driving gear 231 is fixed on the rotating shaft 22 and rotates with the rotation of the rotating shaft 22. The driven gear 233 is sleeved on the connecting shaft 232 and meshes with the driving gear 231, rotating synchronously with the driving gear 231. This gear transmission method has the characteristics of high transmission efficiency, good stability and strong load-bearing capacity, which can ensure the stability and reliability of the grinding device 2 under long-term and high-load operation.

[0035] In one embodiment, the pulverizing component 24 includes a first pulverizing blade 241 fixed at intervals on the rotating shaft 22 and a second pulverizing blade 242 fixed at intervals on the connecting shaft 232. The first pulverizing blade 241 and the second pulverizing blade 242 are arranged alternately, and a partition 31 is provided at the position of the grinding box 3 corresponding to the positions of the first pulverizing blade 241 and the second pulverizing blade 242.

[0036] This design is for reference. Figure 4-6 The staggered arrangement of the first crushing blade 241 and the second crushing blade 242 allows the raw material to be cut and impacted multiple times in different directions when passing through the grinding box 3, thereby achieving more thorough and uniform crushing. This not only improves the crushing efficiency but also ensures that the powder particles are more uniform, meeting the high requirements of subsequent processing and use. The partition 31 can block the first crushing blade 241 and the second crushing blade 242, which not only improves the crushing efficiency of the equipment but also makes the overall structure of the equipment more compact and the layout more reasonable.

[0037] In one embodiment, the cleaning device 6 includes a movable rod 61 passing through the grinding box 3, a scraper 62 disposed on the side of the movable rod 61 located inside the grinding box 3, and a connecting plate 63 fixed on the other side of the movable rod 61. The scraper 62 is disposed in a shape corresponding to the filter screen 25. A handle 64 is fixed on the connecting plate 63. A movable groove 301 for the movable rod 61 to move is provided on the grinding box 3.

[0038] This design is for reference. Figure 3-4 ,as well as Figure 7 The scraper 62 is shaped to correspond to the filter screen 25 and can fit tightly to the surface of the filter screen 25. By moving the moving rod 61, the scraper 62 can easily scrape off the residue on the filter screen 25, avoiding clogging and dust accumulation, ensuring the smooth flow of the filter screen 25 and the grinding efficiency. The design of the connecting plate 63 and the handle 64 allows the operator to easily hold and move the moving rod 61, thereby quickly completing the cleaning work.

[0039] In one embodiment, a brush is fixed to the upper end of the scraper 62.

[0040] This design is for reference. Figure 7 The brush can reach deep into the tiny gaps and hard-to-reach areas of the filter screen 25, and through the brushing action, it can more effectively remove stubborn residues and fine particles attached to the filter screen 25, achieve deep cleaning, and ensure that the filter screen 25 is completely unobstructed.

[0041] Furthermore, if the embodiments involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relation to the specification. The significance or implied number of the indicated technical features is not specified. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
