Coating stirring device

Abstract

The invention provides a coating stirring device, and relates to the technical field of coatings. The coating stirring device comprises a barrel body and a stirring mechanism, wherein an opening-closing cover body is arranged on the top end of the barrel body; an extruding plate for draining liquid in the barrel body is arranged at the cover body; the stirring mechanism is arranged in the barrel body and comprises a driving main shaft, and one end of the driving main shaft penetrates through the bottom part of the barrel body and is connected to a driving element; the driving main shaft is provided with a first storing chamber for accommodating a foldable stirring element; the stirring element comprises telescopic stirring brackets, and telescoping parts for fixedly connecting the stirringbrackets to the driving main shaft in a stretching and closing manner; one end of each stirring bracket is fixedly connected to the end part of the first storing chamber, and the other end of each stirring bracket is movably connected to the corresponding telescoping part. According to the coating stirring device, the stirring element of the stirring mechanism can be stored in the first storing chamber in a folding manner, so that the blockage in feeding is avoided; the extruding plate speeds up discharging, and discharging residues are avoided; the stirring uniformity is ensured through theplurality of stirring brackets; and meanwhile, stable shearing force is formed, so that the materials can be uniformly mixed.

Description

technical field [0001] The invention relates to the technical field of paint, in particular to a paint stirring device. Background technique [0002] Coating refers to a general term for a class of materials that can form a tough protective film when applied to the surface of an object. Generally, it can be divided into solvent-based coatings and water-based coatings. The mixing of materials is a crucial step in the preparation process of coatings. The viscosity of coatings is usually relatively high, which causes certain difficulties to the uniformity of mixing materials. [0003] Paint mixer is a high-efficiency equipment for paint mixing and toning. It can crush, disperse, emulsify, and mix paint. The high-speed operation of the stirring device makes various raw materials mix, and at the same time grinds the raw materials to refine the raw materials. Carry out high-speed strong shearing, impacting, crushing and dispersing of materials to achieve the functions of rapid m...

Problems solved by technology

[0004] The mixing device in the prior art has great limitations in the process of use, and the uniformity of the coating cannot be achieved during the mixing process of materials with high viscosity, high density and poor fluidity; the pressure on the coating at different depths in the cylinder is not Etc., the deeper the paint, the greater the pressure, so the pressure on the stirring paddle is uneven, there is a circulation loop in the stirring of the paint, the homogenization effect is poor, and the paint remains on the inner wall of the cylinder when the paint is output. Miscellaneous foreign matter affects the quality of the paint

[0005] When the existing mixer is stirring the paint, there will be a circular liquid rotation circuit with the stirring shaft as the center, so that some particles with a large mass will stick to the side wall of the liquid tank, while light materials will be rotated away from the liquid tank. The area near the axis causes uneven mixing of raw materials or even stratification

[0006] The traditional paint mixer has poor stirring efficiency, takes a long time to fully mix the paint, and it is laborious to discharge the paint after stirring

When the traditional mixer is discharged, it is manually scooped or directly flows out from the discharge port at the lower end. For the coating with high viscosity and poor fluidity, the slurry will be discharged slowly during the discharge, which is a waste of time. , at the same time there will be paint residue on the mixer, resulting in a waste of resources

The stirring structure is always in the unfolded state, which will cause certain obstacles when feeding, hindering the feeding
