Automatic metal pipeline outer wall plastic coating machine

Abstract

The invention discloses an automatic metal pipeline outer wall plastic coating machine which comprises a fixing frame rail, an intelligent plastic spraying system and two rotary driving fixing frames;the two rotary driving fixing frames of the same structure are symmetrically arranged and installed on the fixing frame rail and can move along the fixing frame rail; when a to-be-sprayed pipeline isinstalled between the two rotary driving fixing frames, the two rotary driving fixing frames retreat to the tail ends of the two sides of the fixing frame rail, and after the to-be-sprayed pipeline is inserted into center holes of the rotary driving fixing frames on the two sides, the rotary driving fixing frames on the two sides advance to a machining position and clamp the to-be-sprayed pipeline; and the intelligent plastic spraying system is arranged on one side or two sides of the to-be-sprayed pipeline and used for coating the to-be-sprayed pipeline with plastic. The automatic metal pipeline outer wall plastic coating machine is high in intelligent degree, high in productivity, high in plastic spraying quality uniformity and good in plastic spraying effect, and is excellent large-diameter metal pipeline plastic spraying equipment.

Description

technical field [0001] The invention relates to the technical field of metal plastic spraying, in particular to an automatic plastic coating machine for the outer wall of a metal pipe. Background technique [0002] Metal plastic-coated or metal-sprayed pipe is a metal composite pipe that melts a layer of non-metallic material on the inner wall of the steel pipe. Water is easy to corrode, pollute, scale, and plastic pipes are not high in strength and poor in fire protection performance. In gas transportation and other fields, due to the excellent performance and low cost of metal plastic-coated pipes, it has become more and more widely used; the demand for large-diameter and super-standard metal-plastic-coated pipes has also increased year by year. The external diameter spraying is all manual spraying, and the operators are prone to occupational diseases due to close contact with volatile chemical materials. However, due to the increasing demand for similar products today, m...

[0002] Metal plastic-coated or metal-sprayed pipe is a metal composite pipe that melts a layer of non-metallic material on the inner wall of the steel pipe. Water is easy to corrode, pollute, scale, and plastic pipes are not high in strength and poor in fire protection performance. In gas transportation and other fields, due to the excellent performance and low cost of metal plastic-coated pipes, it has become more and more widely used; the demand for large-diameter and super-standard metal-plastic-coated pipes has also increased year by year. The external diameter spraying is all manual spraying, and the operators are prone to occupational diseases due to close contact with volatile chemical materials. However, due to the increasing demand for similar products today, manual spraying is also difficult to meet market demand.
