Description
Technical Field
[0001] The utility model belongs to the technical field of paint color mixing, and in particular relates to a color mixing device for paint production. Background Art
[0002] Paint has the advantages of high coating effect, good protective and decorative properties, and its excellent processing performance has been more and more widely used. With the rapid development of the polymer processing industry, powder coatings have also achieved sustained and rapid development in recent years, and have been increasingly valued by consumers. In the production process of paint, the paint needs to be toned, that is, the pigment, filler, auxiliary agent, etc. are mixed and stirred, and organic solvents or water are added to prepare a viscous liquid.
[0003] At present, during the process of mixing and tinting paint, the stirring shaft often inevitably introduces external air into the paint. Due to the high density of the paint, the introduced air cannot be discharged smoothly, so a large number of dense bubbles will be formed in the paint. These bubbles will not only affect the uniformity and stability of the paint, but may also have adverse effects on the subsequent performance of the paint, such as adhesion, drying time, etc., and will also reduce the aesthetics of the paint.
[0004] In addition, the continuous movement of the stirring shaft causes the paint to form an eddy current. The unidirectional inertial motion of this eddy current causes the paint to form an uneven flow pattern in the stirring container. This makes it difficult for the pigments, fillers and other additives in the paint to be fully mixed, resulting in a decrease in the stirring effect. Secondly, the unidirectional inertial motion of the eddy current can also cause the paint to rise and accumulate. This accumulation not only reduces the contact area between the paint and the stirring shaft, reducing the stirring efficiency, but may also cause the paint to form dead corners in the container, making it impossible for the paint in these areas to be fully stirred.
[0005] Therefore, it is very necessary to invent a kind of coating production toning device. Utility Model Content
[0006] In order to solve the above technical problems, the utility model provides a color mixing device for paint production, comprising a paint color mixing machine housing, a turbulent defoamer, a color mixing stirring shaft, a stirring motor and a defoaming motor, wherein the turbulent defoamer is symmetrically installed inside the paint color mixing machine housing, a color mixing stirring shaft is arranged between two of the turbulent defoamers, the color mixing stirring shaft is rotatably installed inside the paint color mixing machine housing, and is fixedly connected to the output end of the defoaming motor fixedly installed outside the paint color mixing machine housing, the defoaming motor is located between the two defoaming motors, the defoaming motor is fixedly installed on the paint color mixing machine housing, and the output end is fixedly connected to the turbulent defoamer;
[0007] The spoiler defoamer includes a vibration sleeve, a spoiler elbow plate, a spoiler baffle, a driving shaft, an anti-vibration bearing, a vibration head and a heating wire assembly. The vibration sleeve is flexibly installed on the upper side of the interior of the paint color mixing machine housing, and a spoiler elbow plate is fixedly installed on the outside of the vibration sleeve, and at least three spoiler baffles are fixedly installed on the spoiler elbow plate; the vibration sleeve is installed with a driving shaft through the anti-vibration bearing, and the upper end of the driving shaft rotates through the paint color mixing machine housing and is fixedly connected to the output end of the stirring motor fixedly installed on the outside of it; the vibration head is fixedly installed on the driving shaft, and a heating wire assembly is installed on the outer sleeve above the driving shaft.
[0008] Preferably, the color mixing and stirring shaft is located between the vibration sleeves, and the spacing between the color mixing and stirring shaft and the vibration sleeve allows the spoiler elbow plate and the spoiler baffle plate to move, and the spoiler baffle plate is a rectangular plate body.
[0009] Preferably, anti-vibration bearings are installed at the lower end and the middle end of the driving shaft respectively, the vibration head is located between the two anti-vibration bearings, and the vibration head contacts the inner wall of the vibration sleeve.

[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] The toning stirring shaft of the utility model is cleverly located between two turbulent defoamers. In the process of stirring the paint, the turbulent defoamers on both sides play a vital role. They can accurately interfere with the paint following the stirring shaft, thereby causing a turbulent effect. This turbulence can significantly prevent the uneven flow pattern of the paint caused by unidirectional inertia, thereby greatly improving the stirring effect. At the same time, the presence of the turbulent defoamer effectively avoids the rising and accumulation of the paint, ensures that the paint can be evenly distributed in the container, and eliminates the generation of stirring dead corners. In addition, the turbulent defoamer not only has the function of optimizing the stirring effect, but also can generate high-frequency vibrations during or after the stirring process. This vibration is highly targeted and can force the bubbles inside the paint to be quickly discharged, significantly reducing the number of dense bubble groups in the paint.

[0024] Embodiment 1:
[0025] Specifically, the color mixing and stirring shaft 3 is located between the vibration sleeve 21. The distance between the color mixing and stirring shaft 3 and the vibration sleeve 21 allows the spoiler elbow plate 22 and the spoiler baffle 23 to move. The spoiler baffle 23 is a rectangular plate.

[0026] Specifically, anti-vibration bearings 25 are installed at the lower end and the middle end of the driving shaft 24 respectively. The vibration head 26 contacts the inner wall of the vibration sleeve 21 to ensure its stability and reliability during operation. The vibration head 26 is located between the two anti-vibration bearings 25, and its position design allows the vibration effect to be transmitted to the paint to the maximum extent.
[0027] Specifically, the heating wire assembly 27 is located above the vibration head 26 and the anti-vibration bearing 25, and the heating wire assembly 27 is installed at the upper position inside the vibration sleeve 21. Heating the paint by the heating wire assembly 27 can not only accelerate the stirring and defoaming process of the paint, but also help eliminate the volatile components in the paint, thereby further improving the quality of the paint.
[0028] Specifically, the paint color mixing machine housing 1 is composed of a shell, a base plate and a discharge pipe mouth.

The color mixing stirring shaft 3 is driven by the stirring motor 4 to rotate inside the paint color mixing machine housing 1, and the rotation of the color mixing stirring shaft 3 drives the paint to be mixed and stirred. At the same time, the defoaming motor 5 drives the driving shaft 24 in the turbulent defoamer 2 to rotate, thereby driving the vibration head 26 to generate high-frequency vibration in the vibration sleeve 21. During the stirring process of the color mixing stirring shaft 3, the turbulent defoamers 2 on both sides interfere with the following paint through the turbulent toggle plate 22 and the turbulent baffle 23, forming a turbulent effect. This turbulent flow can prevent the uneven flow pattern of the paint caused by unidirectional inertia, thereby improving the stirring effect. At the same time, the presence of the turbulent defoamer can also avoid the rise and accumulation of the paint, prevent the generation of a stirring dead angle in the container, and ensure that the paint can be evenly mixed.
