A plate spraying device

Abstract

The invention relates to a plate painting device. The plate painting device comprises a frame. A containing mechanism is arranged on the frame, a sliding rail is arranged above the containing mechanism, a fixed limiting plate is fixedly connected to the sliding rail, and a sliding limiting plate is slidably connected to the sliding rail; and a spring is connected between the sliding limiting plateand the frame. A rotating mechanism is arranged above the containing mechanism. The rotating mechanism comprises a rotating disc and a rotating ring. The rotating ring is rotationally connected to the rotating disc. A driving rod is fixedly connected to the rotating ring. A spraying head is arranged on the driving rod. A driven rod is connected to the rotating disc. A tension spring is connectedbetween the driven rod and the driving rod. A bracket is fixedly connected to the rotating disc. A rolling wheel is rotationally connected to the bracket. A fixing plate is rotationally connected to the bracket. Front limiting columns which abut against the driving rod and rear limiting columns which abut against the driven rod are arranged on the fixing plate. A driving mechanism is arranged on the frame. A driving roll attached to the rolling wheel in a friction manner is connected to the driving mechanism. A push mechanism is arranged on the containing mechanism. By the adoption of the scheme, plates in irregular shapes can be painted.

Description

technical field [0001] The invention relates to the technical field of plate processing, in particular to a plate painting device. Background technique [0002] Spray painting refers to a method in which paint is dispersed into uniform and fine droplets by means of air pressure through a spray gun and applied to the surface of the object to be coated. Existing paint spraying devices mostly spray paint for square plates, that is, control the left and right reciprocating movements of the spray guns, thereby spraying paint on square plates. Since the width of the square plate is a fixed value, it is sufficient to preset the left and right reciprocating movement distance of the spray paint in advance to be equal to the width of the square plate. However, for plates with irregular shapes, irregular plates are not as standardized as square plates, so the width of irregular plates is not a fixed value. Setting the distance of the left and right reciprocating movement of the spray ...

AI Technical Summary

Problems solved by technology

However, for plates with irregular shapes, irregular plates are not as standardized as square plates, so the width of irregular plates is not a fixed value. Setting the distance of the left and right reciprocating movement of the spray gun to a fixed value will cause irregularities. The outside of the board will be sprayed with paint, which will cause excess paint to be wasted, or some parts of the irregular board will not be sprayed with paint, which will affect the painting quality of the irregular board
