This invention uses a cooling device to cool the coating, increasing its hardness and brittleness, and then uses impact crushing to improve the grinding effect and efficiency.

[0004] However, existing powder coating grinding equipment is usually composed of multiple large components, such as grinding chambers, motors, and reducers. The overall size is large and heavy. For example, some large Raymond mills can weigh several tons. With the addition of supporting equipment such as fans and dust collectors, the entire system occupies a large area and is difficult to move, lacking flexibility. Utility Model Content

[0005] The purpose of this invention is to provide a powder coating grinding device to solve the problem mentioned in the background art that the existing grinding devices are too large and cannot be easily moved, thus losing their flexibility.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a powder coating grinding device, including a base and a vertical rod fixedly connected to one side of the top surface of the base. A grinding disc is fixedly connected to the top surface of the base, and a grinding port is opened inside the grinding disc.

[0020] 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. Example

[0021] like Figures 1 to 4 As shown, a powder coating grinding device according to the first aspect of this utility model includes a base 1 and a vertical rod 2 fixedly connected to one side of the top surface of the base 1. A grinding disc 3 is fixedly connected to the top surface of the base 1. A grinding port 4 is opened inside the grinding disc 3. A grinding structure 5 is rotatably connected inside the vertical rod 2, which can extend into the grinding port 4 and be manually rotated as needed to form a grinding effect. A collection structure 6 is slidably connected inside the base 1.

[0022] The technical effects achieved by the above embodiments are as follows: When grinding is required, the coating material to be ground is placed inside the grinding port 4. Then, by rotating the control disk 502, the control disk 502 drives the bottom rotating shaft 501 to rotate. When the rotating shaft 501 rotates, the rotating block 503 drives the bottom grinding roller 505 to slide and rub against the inner wall of the grinding port 4 through the connecting shaft 504, so that the powder coating material inside the grinding port 4 can be ground. Then, when the required degree is reached, simply pull out the baffle plate 601 so that the ground powder passes through the through port 604 into the storage box 603. Finally, pull out the storage box 603 and pour out the ground powder. This device avoids the bulky size of most devices, which makes operation inconvenient. This device uses a simple structure and manual rotation to achieve the required grinding effect, making the device easy to operate and use, while improving flexibility. Example

[0023] like Figure 1 and Figure 2 As shown, a powder coating grinding device includes all the contents of Embodiment 1. In addition, the grinding structure 5 includes a rotating shaft 501 and a control disk 502. The rotating shaft 501 is rotatably connected to one side inside the upright 2, and the bottom end of the rotating shaft 501 extends through the inside of the upright 2 to the outside. The control disk 502 is fixedly connected to the top surface of the rotating shaft 501. The grinding structure 5 also includes a rotating block 503, a connecting shaft 504, and a grinding roller 505. The rotating block 503 is fixedly connected to the bottom end of the rotating shaft 501. The connecting shaft 504 is fixedly connected to one side inside the rotating block 503. The grinding roller 505 is fixedly connected to the bottom end of the connecting shaft 504, and the grinding roller 505 extends into the interior of the grinding port 4. The grinding structure 5 also includes a grinding surface 506, which is disposed on the surface of the grinding roller 505. Both the grinding roller 505 and the connecting shaft 504 are inclined.

[0024] The technical effect achieved by the above embodiment is as follows: When using this utility model, the powder coating to be ground is first placed inside the grinding port 4. At this time, the powder coating will enter the interior by taking advantage of the inclined design of the inner wall of the grinding port 4. Then, by rotating the control disk 502, the control disk 502 drives the bottom rotating shaft 501 to rotate. When the rotating shaft 501 rotates, the rotating block 503 drives the bottom grinding roller 505 to slide and rub against the inner wall of the grinding port 4 by the connecting shaft 504. The inclined design allows the grinding roller 505 to come into close contact with the inner wall of the grinding port 4, so that the powder coating inside the grinding port 4 can form a grinding effect. Then, the rotation continues, so that the grinding surface 506 continuously rubs against the inner wall of the grinding port 4 to achieve the desired powder level. Example

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, a powder coating grinding device includes all the contents of Embodiment 2. In addition, the collecting structure 6 includes a baffle plate 601 and a fixing groove 602. The baffle plate 601 is slidably connected to one side of the surface of the base 1 and is located at the bottom of the grinding disc 3. The fixing groove 602 is opened on one side of the top surface of the baffle plate 601. The collecting structure 6 also includes a storage box 603 and a passage 604. The storage box 603 is slidably connected to one side of the surface of the base 1 and is located at the bottom of the baffle plate 601. The passage 604 is opened on one side of the top surface of the storage box 603.

[0026] The technical effect achieved by the above embodiment is as follows: However, after grinding is completed, the baffle plate 601 can be pulled out by opening the fixed groove 602, so that the ground powder can pass through the through port 604 to the inside of the storage box 603. Finally, the storage box 603 is pulled out horizontally and the ground powder is poured out from the inside. Example

[0027] like Figure 1 and Figure 3 As shown, a powder coating grinding device includes all the contents of Example 3. In addition, the inner wall of the grinding port 4 is provided with a texture opposite to that of the grinding surface 506.

[0028] The technical effect achieved by the above embodiment is that the opposite design of the inner wall of the grinding port 4 and the grinding surface 506 enables the grinding roller 505 to better grind and crush the powder coating when it rotates and rubs inside the grinding port 4, thereby achieving the grinding effect.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
