Spraying device facilitating adjustment of powder supply amount for cast iron pipeline

Abstract

The invention provides a spraying device facilitating adjustment of powder supply amount for a cast iron pipeline, and relates to the technical field of processing of cast iron pipelines. The spraying device comprises a rolling assembly and a powder spraying assembly, wherein the powder spraying assembly comprises a frame and a rolling unit arranged on the frame, the rolling unit comprises a mounting block and a rotating shaft which are arranged at the front end and the rear end, sliding grooves are formed in the two sides of the interior of the mounting block, sliding blocks are movably arranged in the two sets of sliding grooves through driving portions, the rotating shaft is rotationally arranged between the sliding blocks at the front end and the rear end, and a first motor is arranged on the sliding block at the rear end. According to the spraying device, the cast iron pipeline is placed through the rotating shaft, powder in a weighing hopper is sprayed to the pipeline through a powder pump, before the powder is sprayed to the pipeline, the powder in the hopper is fed into the weighing hopper through a feeding portion in a feeding pipe, when a gravity sensor senses the required weight, the feeding pipe stops feeding, the weighed powder is sprayed to the pipeline through the powder pump, so that the powder spraying amount is conveniently controlled, and waste is avoided.

Description

technical field [0001] The invention relates to the technical field of cast iron pipeline processing, in particular to a spray coating device for cast iron pipelines which is convenient for adjusting the powder supply amount. Background technique [0002] Cast iron pipes are cast iron pipes. Cast iron pipes are used for water supply, drainage and gas transmission pipelines. It includes cast iron straight pipes and pipe fittings. The labor intensity is small. According to different casting methods, they are divided into continuous cast iron pipes and centrifugal cast iron pipes. Cast iron pipes are further divided into sand molds and metal molds. According to different materials, they are divided into gray cast iron pipes and ductile iron pipes. According to different interface forms, they are divided into flexible interface, flange interface, self-anchoring interface, rigid interface, etc. Among them, The flexible cast iron pipe is sealed with a rubber ring; the cast iron pi...
