Guardrail surface plastic spraying process

Abstract

The invention relates to the field of guardrail manufacturing, in particular to a guardrail surface plastic spraying process. The process uses a guardrail plastic spraying device, the guardrail plastic spraying device comprises a main body, a conveying groove of an annular structure is formed in the main body, first sliding grooves of an annular structure are symmetrically formed in the inner wallof the conveying groove, and tooth grooves are formed in the first sliding grooves. A plurality of moving gears are symmetrically inserted into the tooth grooves, the moving gears are engaged with the tooth grooves, a plurality of first motors are symmetrically arranged in the first sliding grooves, the first motors and the moving gears are symmetrically arranged, and the output ends of the firstmotors penetrate through the first sliding grooves to be fixedly installed on the moving gears; and fixing rods are arranged at the ends, away from the moving gears, of the first motors, and one endsof the fixing rods are inserted into the first sliding grooves and fixedly installed on the first motors. All-dimensional uniform and stable plastic spraying can be conducted on a metal guardrail, the plastic spraying effect is improved, and the process is suitable for popularization.

Description

technical field [0001] The invention relates to the field of guardrail manufacturing, in particular to a guardrail surface spraying process. Background technique [0002] Guardrail is a facility that is mostly used in residences, highways, commercial areas or public places. It is mainly used to protect and protect human safety or equipment and facilities. It makes a common facility in modern society, which can be used according to the needs of use and the use of the site. Suitable for guardrails of different heights or lengths. [0003] Most of the existing guardrails are made of metal, and they are fixedly installed outdoors. They are exposed to the sun and rain for a long time, and are prone to rust, which affects the protective effect of the service life of the guardrail, and is prone to safety hazards. Therefore, in the production of guardrails During manufacturing, it is necessary to spray plastic on the outer surface of the guardrail to form a package on the outer sur...

Problems solved by technology

[0003] Most of the existing guardrails are made of metal, and they are fixedly installed outdoors. They are exposed to the sun and rain for a long time, and are prone to rust, which affects the protective effect of the service life of the guardrail and is prone to safety hazards. Therefore, in the production of guardrails When manufacturing, it is necessary to spray plastic on the outer surface of the guardrail to form a package on the outer surface of the guardrail to avoid direct exposure of the metal to the air and reduce the degree of corrosion of the metal. However, most of the existing plastic spraying equipment has poor plastic spraying effects. The uniformity of plastic spraying cannot be guaranteed, and at the same time, the spraying time is long and the efficiency is low, which cannot meet the needs of large-scale plastic spraying processing
