Description

Technical Field

[0001] This utility model relates to the field of coating processing equipment technology, specifically to a powder coating dispersion device. Background Technology

[0002] Powder coating is a new type of solvent-free, 100% solid powder coating, mainly composed of solid resin, pigments, fillers, and additives. It is divided into two main categories: thermoplastic and thermosetting. Thermoplastic powder coatings soften and flow when heated, and solidify into a film upon cooling; while thermosetting powder coatings undergo a chemical reaction when heated, forming an infusible and insoluble coating. Powder coatings are prone to clumping during prolonged storage or transportation. Before spraying, it is essential to ensure that any clumped powder is thoroughly dispersed to guarantee proper powder fluidization and spraying. This also helps prevent problems such as color differences, poor surface leveling, and uneven gloss caused by uneven dispersion of the coating components.

[0003] Chinese invention patent CN117797712A discloses a powder coating mixing device and method. Specifically, it describes a process where, during use, a drive motor is powered on. The powder coating is loaded into a bottom chamber. After loading, a push plate is used to move a movable material rack, supported by casters, to move the bottom chamber directly below the top chamber. Before the bottom chamber is pushed under the top chamber, a hydraulic rod lowers a fixing plate to a certain height, allowing the bottom chamber to move under the top chamber. Once the bottom chamber is correctly positioned, the hydraulic rod is retracted, and the fixing plate raises the bottom chamber, securing it to the top chamber. The bottom and top chambers can then be rotated. A controller starts the drive motor, which, via a shaft and mounting plate, rotates the top chamber. The simultaneous rotation of the top and bottom chambers allows the powder coating to mix within them.

[0004] However, in the above technical solution, the powder coating is mixed and stirred only by rotating the bottom box and the top box. The stirring efficiency is low and it is not possible to fully disperse some clumps of powder coating. This results in uneven distribution of the components in the coating. After being sprayed onto the surface of the workpiece, it may form a problematic coating with uneven thickness, poor surface leveling, uneven gloss, etc., which reduces the protective performance of the coating. Utility Model Content

[0005] Therefore, to address the problem that existing mixing devices cannot fully disperse clumps of powder coatings, resulting in difficulties in spraying the coating, and even if the coating can be sprayed onto the workpiece surface, the uneven distribution of the components in the coating may lead to uneven thickness, poor surface leveling, and uneven gloss after curing, thus reducing the protective performance of the coating, one objective of this utility model is to provide a powder coating dispersion device, the specific technical solution of which is as follows:

[0006] A powder coating dispersion device includes a disperser body, a pulverizing device, and a stirring device. The disperser body is provided with a feed hopper, which divides the disperser body into an upper cavity and a lower cavity. The pulverizing device is disposed in the lower cavity and abuts against the discharge port of the feed hopper. The pulverizing device includes a first rotating mechanism and a second rotating mechanism, the first rotating mechanism abutting against the second rotating mechanism, and the first rotating mechanism and the second rotating mechanism rotating in opposite directions. The stirring device is disposed below the pulverizing device.

[0007] Furthermore, the first rotating mechanism includes a first drive motor, a first rotating rod, and a plurality of first crushing blades. The first drive motor is fixedly connected to the outer wall of the disperser body, and the output end of the first drive motor is fixedly connected to the first rotating rod. Each first crushing blade is evenly and equidistantly arranged on the first rotating rod. The end of the first rotating rod away from the first drive motor is rotatably connected to the inner wall of the disperser body, and each first crushing blade rotates in a clockwise direction.

[0008] Furthermore, each of the first crushing blades has a number of first crushing blades evenly and equidistantly arranged on its outer edge, and each first crushing blade is arranged in a clockwise direction on its corresponding first crushing blade.

[0009] Furthermore, the second rotating mechanism includes a second drive motor, a second rotating rod, and a plurality of second crushing blades. The second drive motor is fixedly connected to the outer wall of the disperser body, and the output end of the second drive motor is fixedly connected to the second rotating rod. Each second crushing blade is evenly and equidistantly arranged on the second rotating rod. The end of the second rotating rod away from the second drive motor is rotatably connected to the inner wall of the disperser body, and each second crushing blade rotates counterclockwise.

[0010] Furthermore, each of the second crushing blades has a number of second crushing blades evenly and equidistantly arranged on its outer edge, and each second crushing blade is arranged in a counterclockwise direction on its corresponding second crushing blade.

[0011] Furthermore, the width of the feed hopper at the end furthest from the crushing device gradually decreases towards the end of the feed hopper closer to the crushing device.

[0012] Furthermore, the disperser body is provided with an auxiliary crushing structure, which includes a rocker arm, a rotating shaft and an impact plate. One end of the rotating shaft is fixedly connected to the rocker arm, and the end of the rotating shaft away from the rocker arm passes through the disperser body and is rotatably connected to the inner sidewall of the disperser body.

[0013] Furthermore, the rotating shaft is inclined downwards towards the crushing device.

[0014] Furthermore, the impact plate is provided with a number of impact blocks, each impact block being evenly distributed in a spherical shape.

[0015] Furthermore, the stirring device includes a third drive motor, a stirring plate, and a connecting shaft. The third drive motor is fixedly connected to the outer side wall of the disperser body, and the output end of the third drive motor is fixedly connected to the connecting shaft. The end of the connecting shaft away from the third drive motor passes through the side wall of the disperser body. The stirring plate is disposed on the connecting shaft and fixedly connected to the connecting shaft. A plurality of stirring blocks are disposed on the stirring plate.

[0016] Compared with existing technologies, the beneficial effects of this utility model are as follows: The powder coating dispersion equipment of this utility model provides the space and support required for powder coating dispersion, pulverization, and mixing by setting up a main body for the disperser; by setting up a feed hopper, it guides the material into the pulverizing device in the lower cavity, which also serves as a separator and support; by setting up a pulverizing device, it pulverizes and mixes the blocky or large-particle powder coating falling from the feed hopper, making it meet the required spraying requirements; by setting up a first rotating mechanism and a second rotating mechanism, with their rotation directions opposite, it can more effectively pulverize the powder coating entering the lower cavity, especially for clump-like coatings, improving pulverization efficiency and uniformity; by setting up a mixing device, it fully mixes and disperses the pulverized material, ensuring uniform material distribution and improving the dispersion effect. The powder coating dispersion equipment of this utility model can efficiently disperse clump-like powder coatings, ensuring normal fluidization and spraying operations while also allowing the components in the coating to be fully dispersed, helping to avoid problems such as poor surface leveling and uneven gloss in the coating.

[0030] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0031] like Figures 1-3 As shown, a powder coating dispersion device according to one embodiment of the present invention includes a disperser body 1, a crushing device 2, and a stirring device 3. The disperser body 1 is provided with a feed hopper 11, which divides the disperser body 1 into an upper cavity 12 and a lower cavity 13. The crushing device 2 is disposed in the lower cavity 13 and abuts against the discharge port of the feed hopper 11. The crushing device 2 includes a first rotating mechanism 21 and a second rotating mechanism 22, which abut against each other. The first rotating mechanism 21 and the second rotating mechanism 22 rotate in opposite directions. The stirring device 3 is disposed below the crushing device 2. The disperser body 1 provides the space and support required for the dispersion, crushing, and mixing of powder coatings. The feed hopper 11 guides the material into the crushing device 2 in the lower cavity 13, while also serving as a separator and support. The crushing device 2 crushes the blocky or granular powder coatings falling from the feed hopper 11 to achieve the required particle size. The first rotating mechanism 21 and the second rotating mechanism 22, with opposite rotation directions, can more effectively crush the powder coatings entering the lower cavity 13, especially for clump-like coatings, improving crushing efficiency and uniformity. The stirring device 3 thoroughly stirs and disperses the crushed coatings, ensuring uniform distribution and improving the dispersion effect.

[0032] As a preferred embodiment of this utility model, it may also have the following additional technical features: the stirring device 3 includes a third drive motor 31, a stirring plate 32, and a connecting shaft 33. The third drive motor 31 is fixedly connected to the outer wall of the disperser body 1, and the output end of the third drive motor 31 is fixedly connected to the connecting shaft 33. The end of the connecting shaft 33 away from the third drive motor 31 passes through the side wall of the disperser body 1. The stirring plate 32 is disposed on the connecting shaft 33 and fixedly connected to the connecting shaft 33. Driven by the third drive motor 31, the stirring plate 32 can rotate at high speed, strongly stirring and dispersing the powder coating, thereby improving the dispersion efficiency. The stirring plate 32 is provided with a plurality of stirring blocks 321. The stirring blocks 321 can increase the contact area between the stirring plate 32 and the powder coating, thereby improving the stirring efficiency. In this embodiment, each stirring block 321 is evenly distributed in a spherical shape. In addition, in other embodiments, the shape, number, and specific arrangement of each stirring block 321 can be designed differently according to different needs.

[0033] Please see Figures 4-6 As a preferred embodiment of this utility model, it may also have the following additional technical features: the first rotating mechanism 21 includes a first drive motor 211, a first rotating rod 212 and a plurality of first crushing blades 213. The first drive motor 211 is fixedly connected to the outer wall of the disperser body 1, and the output end of the first drive motor 211 is fixedly connected to the first rotating rod 212. Each first crushing blade 213 is evenly and equidistantly arranged on the first rotating rod 212, ensuring that the first blade can evenly crush the coating when rotating, avoiding local over-crushing or under-crushing. The end of the first rotating rod 212 away from the first drive motor 211 is rotatably connected to the inner wall of the disperser body 1. Each first crushing blade 213 rotates in a clockwise direction, which helps to guide the coating to the second rotating mechanism 22 to achieve a more comprehensive crushing effect.

[0034] As a preferred embodiment of this utility model, it may also have the following additional technical features: Each first crushing blade 213 has a plurality of first crushing edges 2131 evenly and equidistantly arranged along its outer edge, increasing the contact area between each first crushing blade 213 and the coating material. This ensures that each first crushing blade 213 can apply force evenly to the coating material during rotation, allowing for more effective cutting and crushing of the coating material with each rotation. The first crushing edges 2131 are arranged in a clockwise direction on their respective first crushing blades 213, which helps to generate a certain shearing force during blade rotation, making the coating material easier to cut and crush. This, combined with the second rotating mechanism 22, achieves a more comprehensive crushing effect. Simultaneously, the curved first crushing edges 2131 also generate a certain stirring effect during crushing, aiding in the initial dispersion of the coating material. Furthermore, in other embodiments, the number, shape, and arrangement of each first crushing edge 2131 can be configured differently according to different needs.

[0035] As a preferred embodiment of this utility model, it may also have the following additional technical features: the second rotating mechanism 22 includes a second drive motor 221, a second rotating rod 222 and a plurality of second crushing blades 223. The second drive motor 221 is fixedly connected to the outer wall of the disperser body 1, and the output end of the second drive motor 221 is fixedly connected to the second rotating rod 222. Each second crushing blade 223 is evenly and equidistantly arranged on the second rotating rod 222, ensuring that the first blade can evenly crush the coating when rotating, avoiding local over-crushing or under-crushing. The end of the second rotating rod 222 away from the second drive motor 221 is rotatably connected to the inner wall of the disperser body 1. Each second crushing blade 223 rotates counterclockwise, which helps to guide the coating toward the second rotating mechanism 22 to achieve a more comprehensive crushing effect.

[0036] As a preferred embodiment of this utility model, it may also have the following additional technical features: Each second crushing blade 223 has a plurality of second crushing edges 2231 evenly and equidistantly arranged along its outer edge, increasing the contact area between each second crushing blade 223 and the coating material. This ensures that each second crushing blade 223 can apply force evenly to the coating material during rotation, allowing for more effective cutting and crushing of the coating material with each rotation. The second crushing edges 2231 are arranged in a counter-clockwise direction on their respective second crushing blades 223, which helps to generate a certain shearing force during blade rotation, making the coating material easier to cut and crush. This, combined with the second rotating mechanism 22, achieves a more comprehensive crushing effect. Simultaneously, the curved second crushing edges 2231 also generate a certain stirring effect during crushing, aiding in the initial dispersion of the coating material. Furthermore, in other embodiments, the number, shape, and arrangement of each second crushing edge 2231 can be configured differently according to different needs.

[0037] As a preferred embodiment of this utility model, it may also have the following additional technical features: the width of the end of the feed hopper 11 away from the crushing device 2 gradually decreases towards the end of the feed hopper 11 closer to the crushing device 2. This allows the powder coating to flow more smoothly in the feed hopper 11 and gradually gather towards the crushing device 2. The wide end facilitates the reception and containment of a large amount of powder coating, while the narrow end can better control the flow rate and speed of the powder coating, ensuring that the powder coating can enter the crushing device 2 stably and orderly.

[0038] Please see Figure 7As a preferred embodiment of this utility model, it may also have the following additional technical features: An auxiliary crushing structure 4 is provided on the main body 1 of the disperser. The auxiliary crushing structure 4 includes a rocker arm 41, a rotating shaft 42, and an impact plate 43. One end of the rotating shaft 42 is fixedly connected to the rocker arm 41, and the end of the rotating shaft 42 away from the rocker arm 41 passes through the main body 1 of the disperser and is rotatably connected to the inner wall of the main body 1. By rotating the rocker arm 41, the rotating shaft 42 drives the impact plate 43 to rotate and swing within the main body 1 of the disperser. During the rotation and swing, the impact plate 43 impacts the powder coating, further refining the powder coating particles and improving the crushing effect, thus assisting in the crushing of clump-like powder coatings. In this embodiment, the rotating shaft 42 is inclined downwards towards the crushing device 2. The angle of inclination helps to reduce the accumulation and blockage of powder coating near the rotating shaft 42, maintaining the smooth flow of the powder coating. Several impact blocks 431 are provided on the impact plate 43, and each impact block 431 is evenly distributed in a spherical shape. When the impact plate 43 rotates or oscillates, the impact blocks 431 contact the powder coating at multiple points and in all directions, generating impact force. This increases the impact frequency, allowing the powder coating to be more fully dispersed and refined upon impact, improving pulverization efficiency and thus more effectively breaking down the powder coating. The spherical impact blocks 431 reduce the accumulation and retention of powder coating on the impact plate 43, allowing the powder coating to flow and disperse more smoothly. Furthermore, in other embodiments, the user can manually adjust the movement frequency and amplitude of the impact plate 43 as needed.

[0039] The powder coating dispersion device in this embodiment has a reasonable structural design and is easy to use. This structure can also be used for other devices with similar usage requirements. In this embodiment, the powder coating dispersion device can efficiently disperse clumps of powder coating, ensuring normal fluidization and spraying of the powder coating, while also allowing the components in the coating to be fully dispersed, which helps to avoid problems such as poor surface leveling and uneven gloss in the coating.
