Description

Technical Field

[0001] The utility model belongs to the technical field of coating production, in particular to a foam eliminating device for coating production. Background Art

[0002] Paint, traditionally known as varnish in China, is a viscous liquid coated on the surface of an object to be protected or decorated and can form a firmly attached continuous film with the coated object. It is usually based on resin, oil, or emulsion, with or without pigments, fillers, and corresponding additives, and is prepared with organic solvents or water. In the process of processing paint, since the paint is in a flowing state, the bubble-prone substances contained in the paint and the stirring of the mechanical structure will cause bubbles in the paint. If not handled, when the paint is barreled, a large number of bubbles in the barrel will affect the determination of the barreling amount, and a large number of bubbles retained in the barrel will also affect the subsequent use of the paint.

[0003] In contrast, a Chinese patent with authorization announcement number CN218980554U discloses a water-based paint defoaming device, including a supporting mechanism and a defoaming mechanism, wherein the defoaming mechanism is fixedly connected to the top of the supporting mechanism, the defoaming mechanism includes a cutting unit and a boosting unit, the cutting unit is movably connected to the bottom of the defoaming mechanism, the boosting unit is fixedly connected to the surface of the defoaming mechanism, the supporting mechanism is composed of a shell, supporting legs, a defoaming bin, a feed connecting pipe and a discharge pipe, the shell is fixedly connected to the surface of the supporting mechanism, and preferably, the cutting unit is composed of a connecting shell, a lifting rod, a connecting frame, a bubble cutting net and a stepping motor.

[0004] The above patent adopts the setting of pressurizing and defoaming the whole coating, and the coating is processed more at the same time, and the coating volume is large, so the speed of eliminating bubbles inside the coating is slow. Therefore, a new device needs to be designed. Utility Model Content
