[0027] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0028] Example 1: Please refer to Figures 1-6 This utility model provides a technical solution: a vertical powder coating mill based on the adjustment of grinding fineness, including a casing 1 and a support leg 2 at its bottom, a discharge pipe 3 at the bottom of the casing 1, and a grinding adjustment component 5 for adjusting the grinding fineness outside the casing 1.

[0029] The grinding adjustment assembly 5 includes a first grinding disc 51 movably disposed in the housing 1. The position of the first grinding disc 51 can be flexibly adjusted to meet the powder coating requirements of different grinding fineness, thereby improving grinding efficiency and adaptability.

[0030] The casing 1 is equipped with a storage frame 41 for storing powder coating. The bottom of the storage frame 41 is connected to a first telescopic pipe 42, which is connected to a first grinding disc 51. The design of the first telescopic pipe 42 ensures that even if the position of the first grinding disc 51 is adjusted during the feeding process, the powder coating can still be supplied smoothly and without interruption.

[0031] The outer casing 1 is also equipped with a secondary grinding and feeding assembly 7 to assist in the secondary grinding of powder coatings. The design of the secondary grinding and feeding assembly 7 effectively reduces the amount of incompletely ground powder coatings, improving the fineness and consistency of the final product.

[0032] The secondary grinding feeding assembly 7 includes a second support frame 74 disposed on the side of the housing 1, and the second support frame 74 is provided with a feeding pipe 72 for extracting the powder coating in the housing 1 and re-inserting it from the top of the housing 1.

[0033] Furthermore, the grinding adjustment assembly 5 also includes a first support frame 52 fixed to the top of the housing 1. A top plate 53 is fixed to the top of the first support frame 52, and a threaded rod 54 is threadedly connected to the top plate 53. The bottom end of the threaded rod 54 is externally connected to the first grinding disc 51. The distance between the first grinding disc 51 and the second grinding disc 61 can be easily adjusted to meet different grinding needs.

[0034] Furthermore, a handle 55 for rotating the threaded rod 54 is fixed to the top of the threaded rod 54. This improves operational efficiency and allows for rapid pitch adjustment.

[0035] Furthermore, a sliding groove is provided in the housing 1 for the first grinding disc 51 to slide, ensuring the smooth movement of the first grinding disc 51.

[0036] Furthermore, the housing 1 is equipped with a drive grinding assembly 6 that cooperates with the first grinding disc 51 to grind the powder coating. The drive grinding assembly 6 includes a second grinding disc 61 movably disposed in the housing 1, and a connecting plate 62 is fixed to the outside of the second grinding disc 61. The connecting plate 62 is slidably disposed in the housing 1. The design of the second grinding disc 61 and the connecting plate 62 enhances the stability and grinding efficiency of the powder coating.

[0037] Furthermore, a guide trough is provided in the housing 1 to allow the ground powder coating to enter the interior of the housing 1, and the guide trough is located below the second grinding disc 61. The design of the guide trough simplifies the powder coating collection process, improves production efficiency, and reduces material waste.

[0038] Furthermore, the drive grinding assembly 6 also includes a mounting base 63 located beside the housing 1. A drive motor 64 is housed in the mounting base 63. Pulleys 65 are mounted on the output shaft of the drive motor 64 and at the bottom of the second grinding disc 61. A synchronous belt 66 externally connects the two pulleys 65. The design of the pulleys 65 and the synchronous belt 66 ensures stable and efficient power transmission from the drive motor 64 to the second grinding disc 61, thereby improving grinding efficiency.

[0039] Example 2: Please refer to Figure 6 Furthermore, in conjunction with Embodiment 1, the secondary grinding feeding assembly 7 further includes an electric suction pump 71 disposed outside the feeding pipe 72. The feed pipe of the electric suction pump 71 is connected to the housing 1. A second telescopic pipe 73 is disposed on the side of the feeding pipe 72 away from the electric suction pump 71, and the second telescopic pipe 73 is connected to the first grinding disc 51. The design of the electric suction pump 71 and the second telescopic pipe 73 simplifies the secondary grinding process and ensures the efficiency of powder coating grinding.

[0040] In actual operation, firstly, the powder coating to be processed is added to the storage frame 41. Next, the distance between the first grinding disc 51 and the second grinding disc 61 is adjusted according to the particle size of the powder coating. This is achieved by rotating the handle 55, causing the threaded rod 54 to rotate within the top plate 53. Since the threaded rod 54 is threadedly connected to the top plate 53, the first grinding disc 51 will move within the housing 1 until the required distance is reached, at which point the rotation of the handle 55 is stopped.

[0041] During the movement of the first grinding disc 51, the second telescopic tube 73 and the first telescopic tube 42 will extend accordingly to ensure that they are always in communication with the first grinding disc 51, so as to guarantee subsequent material feeding. After adjustment, the first telescopic tube 42 is opened to allow the powder coating in the storage frame 41 to enter the first grinding disc 51 and the first support frame 52.

[0042] Subsequently, the drive motor 64 is started, causing the pulley 65 on its output shaft to rotate. Under the transmission action of the synchronous belt 66, the second grinding disc 61 begins to rotate, and the connecting plate 62 ensures the stable rotation of the second grinding disc 61. Under the combined action of the first grinding disc 51 and the second grinding disc 61, the powder coating is ground. The ground powder coating enters the interior of the housing 1 through the feed chute.

[0043] To avoid any unground portions in the powder coating, the electric feed pump 71 can be turned on, and the powder coating in the casing 1 can be re-feeded into the first grinding disc 51 and the second grinding disc 61 for secondary grinding through the feed pipe 72 and the second telescopic pipe 73. The ground powder coating can then be discharged from the discharge pipe 3.

[0044] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
