Description

Technical Field

[0001] This utility model relates to the field of electrophoretic paint preparation technology, and specifically to an electrophoretic paint preparation device. Background Technology

[0002] The preparation of electrophoretic paint (electrophoretic coating) is a complex and delicate process that requires strict control of raw materials and precise process steps. Its main goal is to prepare film-forming substances (resins), pigments, fillers, and various functional additives into a stable aqueous dispersion or emulsion.

[0003] Existing technologies, such as the utility model patent with publication number CN218307581 U, describe an acrylic resin positive electrophoretic paint preparation device, which relates to the field of electrophoretic paint preparation technology. Specifically, it includes a stirring tank with a heating plate installed on its inner wall. Inside the stirring tank, a rotating rod is coaxially arranged along its length. Both ends of the rotating rod are connected to the stirring tank via rotating bearings. A drive motor is coaxially mounted on the rotating rod and fixed to the top of the stirring tank by a bracket. Multiple equally spaced strip blocks are installed on the rotating rod, arranged along its length. In use, the strip protrusions push the support rod to extend and retract into the support tube as it passes the protrusions, simultaneously compressing a spring. This accumulates elastic potential energy, which in turn acts on the support rod, causing it to drive the stirring blades in a linear reciprocating motion along its length, thereby increasing the mixing rate during electrophoretic paint preparation.

[0004] However, the raw materials of the electrophoretic paint in this patent are prone to clumping before mixing, and the particle size of the paint is not uniform, which affects the mixing rate of the electrophoretic paint.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this invention is to provide an electrophoretic paint preparation device that can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted: an electrophoretic paint preparation device, comprising: a base, a tank fixedly installed on the base, and a grinding mechanism for grinding the raw materials in the tank;

[0009] Furthermore, the limiting track consists of an upper track, an inclined track, and a lower track.

[0010] Furthermore, the spacing between the lower grinding disc and the grinding block is less than or equal to the spacing between the upper track and the lower track.

[0011] Furthermore, the length of the upper track is greater than the sum of the lengths of the inclined track and the lower track.

[0012] Furthermore, both the inner wall of the lower grinding disc and the bottom of the grinding block are conical.

[0013] Furthermore, the lower grinding disc is uniformly provided with through holes.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0022] like Figures 1 to 3 As shown, this utility model discloses an electrophoretic paint preparation device, comprising: a base 1, a tank 2 fixedly installed on the base 1, a stirring mechanism 3 for stirring the solution, and a grinding mechanism 4 for grinding the raw materials in the tank 2; a top cover 21 is fixedly installed on the top of the tank 2, and a discharge port 22 is connected to the bottom of the tank 2. A valve is installed on the discharge port 22. The grinding mechanism 4 grinds the raw materials into fine particles for easy mixing, and the stirring mechanism 3 stirs the solution to make the raw materials in the solution evenly mixed.

[0023] The stirring mechanism 3 includes a motor 31, which is fixedly mounted on the top cover 21. The output shaft of the motor 31 is fixedly connected to the rotating shaft 32, and the rotating shaft 32 rotates and passes through the top cover 21. A stirring paddle 33 is fixedly mounted on the rotating shaft 32, and the lower end of the rotating shaft 32 is rotatably mounted on a support frame 34. The support frame 34 is fixedly mounted on the bottom of the inner wall of the tank 2. The output shaft of the motor 31 drives the rotating shaft 32 to rotate, and the rotating shaft 32 drives the stirring paddle 33 to rotate, so that the stirring paddle 33 stirs the solution and raw materials, and makes the electrophoretic paint evenly mixed.

[0024] The grinding mechanism 4 includes: a transmission belt 41 that drives a transmission shaft 42 to rotate; the inner walls of the transmission belt 41 are sleeved on the rotating shaft 32 and the transmission shaft 42; the lower end of the transmission shaft 42 is rotatably mounted on the top cover 21; and the rotating shaft 32 is parallel to the transmission shaft 42. The rotation of the rotating shaft 32 drives the transmission belt 41 to run, and the transmission belt 41 drives the transmission shaft 42 to rotate; a gear 43 is fixedly mounted on the transmission shaft 42, and the gear 43 meshes with an internal gear ring 44, while the internal gear ring 44 is rotatably mounted on... A fixing ring 45 is fixedly installed on the top cover 21 and the internal gear ring 44. The fixing ring 45 is aligned with the central axis of the internal gear ring 44. The gear 43 is driven to rotate through the transmission shaft 42, which in turn drives the internal gear ring 44 to rotate, and the internal gear ring 44 drives the fixing ring 45 to rotate. A limiting track 46 is provided on the outer wall of the fixing ring 45. A limiting rod 47 is slidably installed in the limiting track 46. The limiting rod 47 is fixedly connected to the feeding hopper 48. The lower end of the feeding hopper 48 is connected to the lower grinding disc 49. Two feeding hoppers 48 are provided. The feeding speed is increased, and the two feeding hoppers 48 limit each other to prevent the feeding hoppers 48 from rotating, which would cause the limiting rod 47 to disengage from the limiting track 46, thus improving the stability of the device; the lower grinding disc 49 is slidably mounted on the rotating shaft 32, and the lower grinding disc 49 is evenly provided with through holes, through which the raw material is filtered, so that the raw material to be ground can enter the solution through the through holes. The lower grinding disc 49 and the grinding block 410 grind the raw material, and the grinding block 410 is fixedly mounted on the rotating shaft 32; The rotation of the fixed ring 45 causes the inner wall of the limiting track 46 to push the limiting rod 47, which in turn causes the limiting rod 47 to move the feeding hopper 48 in the vertical direction. The feeding hopper 48 then moves the lower grinding disc 49. When the lower grinding disc 49 rises, it cooperates with the grinding block 410 to grind the raw material into uniformly sized particles, thus improving the quality of the finished product. When the lower grinding disc 49 falls, it is partially below the liquid surface, allowing the raw material to be submerged in the solution. This allows the ground raw material to pass through the through hole, improving the efficiency of the raw material passing through the through hole.

[0025] It should be added that the inner wall of the lower grinding disc 49 and the bottom of the grinding block 410 are both conical, so that the grinding block 410 and the inner wall of the lower grinding disc 49 can cooperate with each other to grind the raw material into uniformly sized particles. Furthermore, the ground raw material will slide down the inner wall of the lower grinding disc 49, making it more likely for the raw material to pass through the through hole.

[0026] Furthermore, the limiting track 46 is composed of an upper track, an inclined track, and a lower track, and the distance between the lower grinding disc 49 and the grinding block 410 is less than or equal to the distance between the upper track and the lower track. When the limiting rod 47 slides on the upper track, the lower grinding disc 49 and the grinding block 410 can cooperate to grind the raw material. When the limiting rod 47 slides on the lower track, the bottom of the lower grinding disc 49 moves below the liquid surface.

[0027] It should be noted that the length of the upper track is greater than the sum of the lengths of the inclined track and the lower track. When the internal gear ring 44 drives the fixed ring 45 to rotate, the movement time of the limit rod 47 in the upper track is greater than the movement time of the limit rod 47 in the inclined track and the lower track, so that the grinding time of the raw material is longer, ensuring the grinding effect.

[0028] Working principle:

[0029] While grinding the electrophoretic paint raw material, the solution containing the ground electrophoretic paint raw material is stirred. During the grinding process, the lower grinding disc 49 moves back and forth along the rotating shaft 32. When the lower grinding disc 49 rises to the top, it cooperates with the grinding block 410 to grind the raw material into uniformly sized particles, improving the quality of the finished product. When the lower grinding disc 49 descends to its lowest point, part of it is below the liquid surface, facilitating the raw material to fall into the lower grinding disc 49 through the feed hopper 48 and be submerged in the solution. This allows the ground raw material to pass through the through hole, improving the efficiency of the material passing through the through hole. In addition, the unground raw material is wetted after being submerged in the solution, making it easier to grind again, improving the grinding efficiency. Furthermore, the grinding process is automated, improving the practicality of the device.

[0030] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.
