Coating equipment and technological method for guardrail stand column

Abstract

The invention discloses coating equipment for a guardrail stand column. The coating equipment for the guardrail stand column comprises a transverse spraying system and a transverse heating curing system, the spraying system comprises a powder room, an outer spraying movement device is installed at the top of the powder room, two sets of inner spraying movement devices which are oppositely arranged are arranged on the two sides of the powder room, and two sets of clamping rotation devices which are oppositely arranged are arranged in the powder room. The invention also discloses a coating technological method for the guardrail stand column. The method comprises the steps that a feeding trolley lifts the guardrail stand column and conveys the guardrail stand column into the powder room, after the stand column is positioned in the powder room, clamping jaws stretch into the interior to support the two ends and rotate, an inner spray gun and an outer spray gun move linearly to conduct rotary spraying on the inner surface and the outer surface of the stand column, and automatic conveying and transverse heating curing are conducted after spraying. According to the coating equipment and the coating technological method for the guardrail stand column, powder can be quickly cured, and the adhesive force of a coating can be improved; the powder coating can be more uniform, and the thickness range of the coating is reduced; and internal spraying and external spraying can be achieved at the same time, the equipment occupied area is small, the equipment integration degree is high, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a coating equipment and a process method, in particular to a guardrail post coating equipment and a process method, belonging to the technical field of powder coating. Background technique [0002] At present, most of the coating equipment for the guardrail column adopts the form of the vertical suspension of the workpiece on the spraying chain. The internal spraying and external spraying of the column are sprayed twice. The distance of the vertical coating is different from the spraying gun, resulting in the film thickness of the coating. The extreme difference is large, the length of the spraying chain and the length of the powder room are increased by two sprayings, the floor area is large, and the equipment cost is high. [0003] The curing method adopted after spraying is generally hot air circulation or infrared radiation heating; the process of heating and curing by hot air circulation is slow and the coating is easily p...

[0002] At present, most of the coating equipment for the guardrail column adopts the form of the vertical suspension of the workpiece on the spraying chain. The internal spraying and external spraying of the column are sprayed twice. The distance of the vertical coating is different from the spraying gun, resulting in the film thickness of the coating. The extreme difference is large, the length of the spraying chain and the length of the powder room are increased by two sprayings, the floor area is large, and the equipment cost is high

[0003] The curing method adopted after spraying is generally hot air circulation or infrared radiation heating; the process of heating and curing by hot air circulation is slow and the coating is easily polluted by dust and exhaust gas, which affects the adhesion of the coating; the far-infrared heating method can make the powder Rapid curing but poor oven temperature uniformity, affecting the overall coating adhesion

[0004] The market lacks a guardrail column coating equipment and process that can quickly solidify the powder and improve the coating adhesion
