Coating-film-thickness-automatically-adjustable curtain coating machine

Abstract

The invention discloses a coating-film-thickness-automatically-adjustable curtain coating machine. The curtain coating machine comprises a machine frame, wherein conveying mechanisms are arranged on the machine frame and are respectively arranged at the left and right ends of the machine frame, a receiving groove is formed between the conveying mechanisms, a curtain coating groove is formed above the receiving groove, a discharging opening of the curtain coating groove points at the receiving groove, the receiving groove is connected with a coating material liquid container through a pump, the curtain coating groove is provided with a height adjusting device and a detecting device which is used for detecting the thickness of a machined part, and the detecting device is arranged between a machined part charging opening and the height adjusting device. According to the curtain coating machine, by adopting the technical scheme, regardless of whether paint of different brands is applicable to one kind of sheet materials or paint of the same brand is applicable to a variety of sheet materials, required coating film thicknesses can be machined in the same machine, so that the applicable range is enlarged, and the operating steps are reduced. The curtain coating machine is simple in structure and convenient in operation, and machining parameters can be flexibly set according to the needs of machining, so as to adjust the coating film thickness, so that the usable range is enlarged, and the popularization is facilitated.

Description

technical field [0001] The invention belongs to the field of plate painting processing equipment, and relates to a curtain drenching machine, in particular to an automatic adjustable coating film thickness drenching curtain machine. Background technique [0002] Nowadays, in the processing of boards such as floors, it is necessary to process the surface coating to enhance the decorative effect of the surface. Traditional paint coating methods include manual brushing, spraying, roller coating, etc. These methods have disadvantages such as low efficacy, uneven coating distribution, uneven thickness, and large loss of raw materials, which affect the coating quality. [0003] The currently used curtain drenching machine for paint coating uses a conveying mechanism to pass the plate to be coated under the head of the drenching machine. The coating is evenly coated on the surface of the plate to be coated to realize coating coating. Compared with the previous method, this drench...

AI Technical Summary

Problems solved by technology

However, the conveying device and the head of the curtain drenching machine of this kind of machinery are integral frame structures, that is, the head of the drenching machine and the conveying device share an integral support support. In actual use, the distance between the nozzle of the drenching machine and the conveying device It is certain, but the paint is viscous, and the viscosity of different brands of paint is not the same, so the thickness of the coating film formed by different brands of paint on the board is not the same in the same spraying time. When painting, boards of different thicknesses have different requirements for coating film thickness. This kind of curtain machine cannot meet the production and application under the above conditions.
