Paint spraying device for steel bar for truss and application method thereof

Abstract

The invention discloses a paint spraying device for a steel bar for a truss and an application method thereof. The paint spraying device comprises a base. The paint spraying device sprays paint in a protective cover, and smelly gas in the protective cover is sent into a box body through an induced draft fan and a gas guide tube. After the peculiar smell of the smelly gas is removed through an activated carbon layer in the box body, the gas is exhausted through a gas exhaust tube. Thus, by the operation of removing the peculiar smell in the paint spraying process, harmful substances generated in the paint spraying process are effectively adsorbed and collected. Therefore, the health of staff and the good working environment are ensured, and the physical and mental health of staff is helped.The paint spraying device works through an air blower and an air heater, so that hot air is blown out from an air outlet of an air knife so as to dry the paint-sprayed steel bar, therefore the steelbar does not need a drying process and can be used immediately, and thus the efficiency is greatly improved. Moreover, the steel bar does not need to be moved and rotated, and therefore the influenceon a paint surface in the movement and rotation process is effectively avoided.

Description

technical field [0001] The invention relates to the field of painting, in particular to a steel bar painting device for trusses and an application method thereof. Background technique [0002] Truss: A structure consisting of members connected to each other by hinges at both ends. The truss is composed of straight rods and generally has a plane or space structure of triangular units. The truss members mainly bear axial tension or pressure, so that the strength of the material can be fully utilized. When the span is large, it can save materials compared with solid web beams, reduce self-weight and Increase stiffness. Trusses are widely used in the construction field. In order to delay the corrosion rate of steel bars in trusses, it is necessary to spray paint on the steel bars for trusses during the production of trusses. The current steel bars for trusses are painted manually, and the speed of steel bar painting is relatively slow. , the painting quality of steel bars is n...

Problems solved by technology

Trusses are widely used in the construction field. In order to delay the corrosion rate of steel bars in trusses, it is necessary to spray paint on the steel bars for trusses during the production of trusses. The current spraying of steel bars for trusses is done manually, and the speed of steel bar painting is relatively slow. , the painting quality of steel bars is not uniform, and the labor cost is relatively high, so a steel bar painting device for trusses is needed to solve these problems
