Variable-diameter mixing machine for coating processing

Abstract

The invention discloses a variable-diameter mixing machine for coating processing. The machine comprises a mixing tank, a horizontal conveying tank and a circulating tank, wherein a speed reducer is connected to the lower end of an output shaft of a first motor; two groups of stirring components are arranged on a stirring rod; each stirring component comprises a fixed sleeve, a movable sleeve, a support rod, an elastic stirring fin and a balancing weight; the bottom part of a lower hopper is communicated with the horizontal conveying tank; the circulating tank is communicated to the upper side of the right end of the horizontal conveying tank; a plastic hose is communicated to one end of a circulating pump, and winds on an adjusting mechanism; the adjusting mechanism is formed by an upper guide wheel, a lower guide wheel, a pipe trough and an installation plate. According to the variable-diameter mixing machine for coating processing provided by the invention, the arranged stirring components are used for mixing raw materials in a stirring barrel, the stirring speed of a stirring shaft is adjusted through the speed reducer during a stirring process, and the degrees of outwards stretching the elastic stirring fins through the balancing weights are different according to different rotary speeds, so that the stirring radius is changed, stirring are carried out at different positions, and the stirring effect is improved.

Description

technical field [0001] The present invention relates to a wide range, in particular to a mixer for processing variable-diameter paints. Background technique [0002] Powder coating is a completely different form from general coatings, it exists in the state of fine powder. Because no solvent is used, it is called powder coating. Powder coating is a new type of solvent-free, 100% solid powder coating, which has the characteristics of no solvent, no pollution, saving energy and resources, reducing labor intensity and high mechanical strength of the coating film. [0003] It comes in two broad categories: thermoplastic powder coatings and thermoset powder coatings. [0004] Thermoplastic powder coatings are composed of thermoplastic resins, pigments, fillers, plasticizers and stabilizers. Thermoplastic powder coatings include: polyethylene, polypropylene, polyester, polyvinyl chloride, chlorinated polyether, polyamide, cellulose, and polyester. [0005] Thermosetting powder...

AI Technical Summary

Problems solved by technology

[0006] The raw materials need to be mixed during the processing of powder coatings. Due to the large amount of raw materials added, it takes a long time to stir and mix. Ordinary stirring is to form a swirling flow inside the blades to stir and mix the raw materials. However, due to the periodicity of rotation, the internal liquid , especially in the vertical direction, it is difficult to mix the raw materials evenly, and a large amount of them accumulates in the upper part, which affects the coating processing and production
