Abstract

The invention discloses a spray gun device for drawing oil painting. The spray gun device comprises a gun body, a paint box, a sprayer, a rotary disk, a rotary shaft, a first bracket, a rotary platform, positioning teeth, a rotary column, a second bracket, a third bracket, a pressing plate and a torsional spring, wherein a conveying passage is arranged in the gun body; a spraying end is arranged at the head of the gun body; the gun body is connected with a control handle, and the control handle compresses the air in the gun body to spray the pigment, conveyed into the conveying passage, of thepaint box out of the spraying end; a plurality of spraying holes are formed in the sprayer; the sprayer is arranged on the rotary disk; the diameters of the spraying holes are different; the rotary disk is coaxially connected with the rotary shaft; the rotary shaft is rotatably arranged on the first bracket; the rotary platform is connected with the rotary shaft; a positioning groove embedded inthe positioning teeth is formed in the rotary platform; the positioning teeth are connected with the rotary column; the rotary column is rotatably arranged on the second bracket; the torsional springis arranged on the rotary column in a sleeving manner; and the pressing plate is arranged on the positioning teeth. The spray gun device can flexibly and conveniently switch the sprayer with differentspraying hole sizes to meet different drawing demands.

Description

technical field [0001] The invention relates to the technical field of painting equipment, in particular to a spray gun device for oil painting. Background technique [0002] Oil painting is a kind of painting made on canvas, linen, cardboard or wooden board with quick-drying vegetable oil (linseed oil, poppy oil, walnut oil, etc.) and pigments. At present, painters generally use brushes to paint manually. [0003] For the painting needs of small painting size, manual painting by the artist can meet the requirements. However, when the painting size is large, the manual painting method is time-consuming and labor-intensive, and the labor intensity of the painter is high. The spray gun device for painting came into being. However, in the spray gun device, the spray hole size of the spray head is fixed, and the spray painting range is certain. If the spray hole size is large, fine painting cannot be carried out. If the spray hole size is small, then The painting efficiency ca...

Problems solved by technology

[0003] For the painting needs of small painting size, the painter can meet the requirements by manual painting. However, when the painting size is large, the manual painting method is time-consuming and labor-intensive, and the labor intensity of the painter is high.

The spray gun device for painting came into being. However, in the spray gun device, the spray hole size of the spray head is fixed, and the spray painting range is certain. If the spray hole size is large, fine painting cannot be carried out. If the spray hole size is small, then The painting efficiency cannot be guaranteed, so the nozzle needs to be replaced frequently to meet different painting needs, and the replacement process of the nozzle is very troublesome
