Description

Technical Field

[0001] This utility model relates to the field of color mixing machine technology, and in particular to a multi-point feeding mechanism for a color mixing machine. Background Technology

[0002] With the improvement of industrial production and people's living standards, the demand for precise color matching is increasing. In many industries such as construction, automobiles, electronics, furniture, and printing, the accuracy and consistency of color are crucial to product quality and aesthetics. For example, the color of architectural coatings needs to be highly matched with the design scheme to create the expected visual effect; the uniformity and accuracy of automotive paint color not only affect the appearance but also relate to the brand image of the car. Therefore, as a key piece of equipment for achieving precise color matching, improving the performance of color mixing machines is of great significance.

[0003] Powder coatings are a type of solid coating with numerous beneficial effects, including being solvent-free, pollution-free, recyclable, and environmentally friendly, making them widely used. In existing technologies, traditional powder coatings require a color mixing machine for preparation. These machines are equipped with multiple mixing tubes, and the material is dispensed by controlling valves. However, traditional color mixing machines mostly rely on direct valve dispensing, lacking proper mixing during the dispensing process. Furthermore, powder coatings may clump due to moisture or pressure during storage, and direct dispensing can easily lead to dispensing difficulties. Therefore, this invention proposes a multi-point dispensing mechanism for a color mixing machine to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multi-point feeding mechanism for a color mixing machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-point feeding mechanism for a color mixing machine includes a rotating disk rotatably connected to the inner wall of the color mixing machine body. Multiple material pipes are fixedly connected to the upper end of the rotating disk, and these material pipes are circumferentially spaced at equal intervals. Each of the multiple material pipes is equipped with a stirring mechanism for stirring the materials. Each stirring mechanism includes a stirring rod rotatably connected to the bottom of the material pipe, and multiple sets of stirring blades are fixedly connected to the side wall of the stirring rod. The color mixing machine body is internally equipped with a driving mechanism for driving the stirring mechanism, and also with a rotating mechanism for rotating the rotating disk.

[0007] Preferably, the driving mechanism includes an internal gear ring fixedly connected to the inner wall of the color mixing machine body, and gears are fixedly sleeved on the upper ends of the plurality of stirring rods, and the plurality of gears mesh with the internal gear ring.

[0008] Preferably, each of the material pipes is equipped with a solenoid valve at its lower end, and the solenoid valves pass through the rotating disc and are fixedly connected to it.

[0009] Preferably, the rotating mechanism includes a motor fixedly connected to the upper end of the color mixing machine body, a rotating rod fixedly connected to the end of the output shaft of the motor, and the lower end of the rotating rod fixedly connected to the center of the rotating disk.

[0010] Preferably, a fixing ring is fixedly sleeved on the side wall of the color mixing machine body, and four electric push rods are provided on the fixing ring in a circumferentially evenly spaced manner, with the telescopic ends of the four electric push rods fixedly connected to the lower end of the fixing ring.

[0011] Preferably, the lower ends of the four electric push rods are all fixedly connected to a base, and the bases are all fitted with anti-slip rubber sleeves.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By setting up a stirring mechanism, a driving mechanism, and a rotating mechanism, during material feeding, the material bucket is placed under the main body of the color mixing machine. The output shaft of the drive motor rotates, driving the rotating rod and rotating disk to rotate, causing the material tube to rotate. During the rotation, the solenoid valve is opened to complete the feeding. During the feeding process, multiple stirring mechanisms rotate, and multiple gears rotate around the rotating rod as the axis. Under the action of the internal gear ring, the gears meshing with it rotate, thereby driving multiple stirring rods and stirring blades to rotate, realizing the stirring of the material, avoiding material agglomeration, and affecting the feeding. At the same time, it makes the powder coating in a more smooth state, and can pass through the solenoid valve more smoothly during the feeding process, reducing feeding difficulties caused by excessive frictional resistance.

[0014] 2. By setting up an electric push rod and a fixed ring, the extension or retraction end of the electric push rod is driven to move, thereby moving the color mixing machine body and realizing the lifting and lowering of the color mixing machine body. It can adjust the distance between the solenoid valve and the material barrel, avoiding excessive distance and the powder coating being affected by external wind force, which would cause the material feeding position to deviate, greatly improving the practicality of the device.

[0021] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0022] Reference Figures 1-5 A multi-point feeding mechanism for a color mixing machine includes a rotating disk 12 rotatably connected to the inner wall of the color mixing machine body. Multiple material pipes 11 are fixedly connected to the upper end of the rotating disk 12. The multiple material pipes 11 are circumferentially and evenly spaced. Each of the multiple material pipes 11 is equipped with a stirring mechanism for stirring materials. The stirring mechanism includes a stirring rod 10 rotatably connected to the bottom of the material pipe 11. Multiple sets of stirring blades 9 are fixedly connected to the side wall of the stirring rod 10. Electromagnetic valves 13 are installed at the lower end of each of the multiple material pipes 11. The multiple electromagnetic valves 13 pass through the rotating disk 12 and are fixedly connected to it. A controller is provided on the rear wall of the color mixing machine body 1. The controller can control the closing of the multiple electromagnetic valves 13. A feed inlet is provided at the upper end of the color mixing machine body 1, through which materials can enter the material pipes 11.

[0023] The main body 1 of the color mixing machine is equipped with a drive mechanism for driving the stirring mechanism. The drive mechanism includes an internal gear ring 7 fixedly connected to the inner wall of the main body 1 of the color mixing machine. The upper ends of multiple stirring rods 10 are all fixedly sleeved with gears 6, and multiple gears 6 mesh with the internal gear ring 7.

[0024] The main body 1 of the color mixing machine is equipped with a rotating mechanism for rotating the rotating disk 12. The rotating mechanism includes a motor 2 fixedly connected to the upper end of the main body 1 of the color mixing machine. The output shaft of the motor 2 is fixedly connected to a rotating rod 8. The lower end of the rotating rod 8 is fixedly connected to the center of the rotating disk 12. The rotating disk 12 is circular. By setting the rotating mechanism, the solenoid valve 13 and the material pipe 11 will rotate continuously during material feeding. The advantage of continuous rotation is that the position can be continuously adjusted to complete multi-point feeding and avoid material accumulation in one place, which would affect the subsequent mixing effect.

[0025] A fixing ring 4 is fixedly sleeved on the side wall of the color mixing machine body 1. Four electric push rods 3 are arranged circumferentially and evenly. The telescopic ends of the four electric push rods 3 are fixedly connected to the lower end of the fixing ring 4. The lower ends of the four electric push rods 3 are fixedly connected to the base 5. Anti-slip rubber sleeves are fitted on the multiple bases 5. The anti-slip rubber sleeves can improve the anti-slip effect of the color mixing machine body 1 and achieve a certain buffering and noise reduction effect during use.

[0026] In use, during material feeding, the material bucket is placed below the main body 1 of the color mixing machine. The output shaft of the drive motor 2 rotates, causing the rotating rod 8 and the rotating disk 12 to rotate, thus rotating the material tube 11. During rotation, the solenoid valve 13 is opened to complete the feeding. During feeding, multiple stirring mechanisms rotate, and multiple gears 6 rotate around the rotating rod 8. Under the action of the internal gear ring 7, the gears 6 meshing with it rotate, thereby driving multiple stirring rods 10 and stirring blades 9 to rotate, thus stirring the material and preventing the material from clumping and affecting feeding. At the same time, the powder coating is in a relatively smooth state, and it can pass through the solenoid valve 13 more smoothly during feeding, reducing feeding difficulties caused by excessive frictional resistance. The extension or retraction end of the drive electric push rod 3 extends or retracts, driving the fixed ring 4 to move, thereby driving the main body 1 of the color mixing machine to move, realizing the lifting and lowering of the main body 1 of the color mixing machine. It can adjust the distance between the solenoid valve 13 and the material bucket to avoid the distance being too large, which would cause the powder coating to be affected by external wind force and cause the feeding position to deviate.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
