Description

Technical Field

[0001] This application relates to the field of coating production technology, and in particular to a powder coating grinding device. Background Technology

[0002] Powder coatings are solid powdered synthetic resin coatings composed of solid resin, pigments, fillers, and additives. Powder coatings do not contain organic solvents and do not produce organic solvent volatilization during production and application, which can reduce pollution to the atmospheric environment and reduce the harm to the health of operators. At the same time, powder coatings are widely used because they have high application rate, strong adhesion, are not easy to fall off, and have excellent anti-corrosion and decorative properties.

[0003] The production process of powder coatings generally includes steps such as premixing, feeding, melt extrusion, cooling and pressing, and crushing and grinding. The final crushing and grinding requires the paint flakes to be crushed by a crusher, and then the fragments are sucked into the grinding chamber of the grinder by the airflow of the blower for grinding. After grinding, the material is discharged after being screened by a screening structure.

[0004] Because the grinding process of powder coatings generates a lot of dust and needs to be carried out in a closed environment, the sealing between the grinding chamber and the cover plate of the grinder is very important. Existing technologies mostly use compression sealing, but when there is a certain pressure or suction in the grinding chamber, compression sealing will also have certain limitations. Moreover, after a certain period of compression sealing, it will make it difficult to open the cover plate, affecting the performance. Therefore, it is necessary to design a powder coating grinding device with good sealing performance and easy opening. Utility Model Content

[0005] This application provides a powder coating grinding device that has good sealing performance and is easy to open.

[0006] The powder coating grinding device provided in this application adopts the following technical solution:

[0007] A powder coating grinding device includes a frame and a grinding chamber mounted on the frame. A top cover is movably connected to the grinding chamber. An annular portion with the same size as the top cover is provided at the upper end of the grinding chamber. A locking portion is provided on the side of the grinding chamber. The locking portion includes a first arc-shaped portion and a second arc-shaped portion that are movably connected. The inner sides of the first and second arc-shaped portions are provided with inclined surfaces. The inner sides of the first and second arc-shaped portions can respectively connect with the annular portion and the top cover. Locking buckles are provided at the ends of the first and second arc-shaped portions.

[0008] Preferably, the frame is provided with a fixed cylinder, and the first arc-shaped part and the second arc-shaped part are rotatably connected to the fixed cylinder. The side of the fixed cylinder is provided with a limiting rod, and the limiting rod can be connected to the outer side of the first arc-shaped part or the second arc-shaped part.

[0009] Preferably, the grinding chamber has a feed inlet and a discharge outlet on its side, the top cover has a drive mechanism and a grinding blade is connected to the drive mechanism, the connection between the annular part and the top cover has an inclined surface, and the connection between the annular part and the top cover has a sealing ring, and there are multiple sealing rings arranged concentrically.

[0010] Preferably, the lower inner side of the top cover is provided with a slope, and the upper inner side of the annular portion is provided with a corresponding inclined protrusion.

[0011] Preferably, the top cover is provided with a handle and the handle is arranged in the radial direction of the top cover.

[0012] Preferably, the locking buckle is provided at the end of the first arc-shaped portion or the second arc-shaped portion. The locking buckle includes a first buckle ring, a rotating handle is connected to the first buckle ring, and a second buckle ring is rotatably connected to one end of the rotating handle. The end of the second arc-shaped portion or the first arc-shaped portion is provided with a groove or protrusion that is connected to the second buckle ring.

[0013] Preferably, the rotating handle has an arc-shaped structure, and the rotating handle can be set to fit against the outer side of the first arc-shaped part or the second arc-shaped part.

[0014] Preferably, a rubber liner is provided inside the inclined surface of both the first arc-shaped portion and the second arc-shaped portion.

[0015] Preferably, both the annular portion and the outer ends of the top cover are provided with rounded corners.

[0016] Preferably, the top cover has a transparent observation window.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] 1. This application provides an annular portion corresponding to the size of the top cover at the upper end of the grinding chamber, and a locking portion on the side of the grinding chamber. The annular portion and the top cover can be aligned and positioned by the first arc-shaped portion and the second arc-shaped portion. At the same time, since the inner sides of the first arc-shaped portion and the second arc-shaped portion are provided with inclined surfaces, the annular portion and the top cover can be pressed and fixed by the inclined surfaces, resulting in good overall sealing. The locking buckles provided at the ends of the first arc-shaped portion and the second arc-shaped portion facilitate closing and opening, making it convenient to use.

[0019] 2. By providing a fixed cylinder on the frame, it is convenient to connect the first arc-shaped part and the second arc-shaped part. At the same time, a limit rod is provided on the side of the fixed cylinder to limit the opening angle of the first arc-shaped part and the second arc-shaped part, thereby avoiding the opening angle of the first arc-shaped part and the second arc-shaped part and facilitating connection.

[0020] 3.

[0021] 4. By setting a first buckle, a rotating handle, and a second buckle, it is convenient to connect and fix the first arc-shaped part and the second arc-shaped part, ensuring a tight connection between the ring part and the cover. At the same time, the rotating handle has an arc-shaped structure and can fit the first arc-shaped part or the second arc-shaped part, making it convenient to fix and easy to use.
