Technical Field

[0001] The utility model relates to the technical field of mixing devices, in particular to a mixing device for pigment production. Background Art

[0002] When pigments are produced, their powders need to be mixed to form powders of different colors. Horizontal mixers are mostly used for mixing and stirring. They are mainly composed of a U-shaped container and spiral stirring blades. The forward and reverse rotating spirals are installed on the same horizontal axis to form a low-power and high-efficiency mixing environment, which can form more vortices in the flow of materials, speed up the mixing speed, and improve the mixing uniformity.

[0003] However, the installation shaft of the existing horizontal mixer for the spiral ribbon stirring blades directly passes through the interior of the mixing box. The integrated structure of the shaft makes it impossible to disassemble it, so that the spiral ribbon stirring blades cannot be easily disassembled and assembled, making it inconvenient to clean the inner wall of the mixing box during subsequent cleaning of the device, reducing the convenience of its maintenance. Utility Model Content

[0004] The purpose of the utility model is to provide a mixing device for pigment production, so as to solve the problem that the one-piece structure of the main shaft proposed in the above-mentioned background technology makes it impossible to disassemble, so that the spiral stirring blades cannot be easily disassembled and assembled, and thus it is not convenient to clean the inner wall of the mixing box during subsequent cleaning of the device.

[0005] To achieve the above object, the utility model provides the following technical solution: a mixing device for pigment production, comprising:

[0014] Compared with the prior art, the beneficial effect of the utility model is that the utility model makes the traditional one-piece main shaft present a split structure distribution through the setting of the detachable stirring component, so that the main shaft can be disassembled, and then the inner wall of the mixing box can be cleaned conveniently, which greatly improves the convenience of cleaning. At the same time, the extrusion structure setting of the sealing component effectively ensures its sealing effect and avoids the dispersion of dust during mixing.

[0015] (1) The utility model provides a stirring assembly so that the traditional one-piece main shaft is designed in sections, so that the main shaft inside the mixing box can be disassembled. When cleaning the inner wall of the mixing box, the main shaft and the spiral stirring blades inside the mixing box can be removed, thereby improving the convenience of cleaning the inner wall of the mixing box.

[0016] (2) The utility model can squeeze and seal the feeding port by setting a sealing component. Compared with the traditional switch type door body, the sealing effect is better and the dispersion of dust can be effectively avoided. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the support shaft 31 away from the rotating shaft 33 is connected to the output shaft of the servo motor 4. By starting the servo motor 4, the support shaft 31 and the rotating shaft 33 can be driven to rotate, thereby causing the spiral stirring blade 34 to rotate, thereby completing the stirring and mixing of the pigment powder. The segmented connection between the support shaft 31 and the flat key 32 is convenient for disassembly of the rotating shaft 33 and the spiral stirring blade 34, thereby facilitating the cleaning of the inner wall of the mixing box 2.
