Steel tube surface multi-pattern line spraying device

Abstract

The invention discloses a steel tube surface multi-pattern line spraying device which includes a spraying machine. A processing cavity is arranged in the spraying machine in a left-and-right through manner, a circular rotating cavity is arranged in the circumferential wall of the processing cavity in a communicating manner, a rotary disc is rotatably arranged in the rotating cavity, a gear ring isfixedly arranged on the outer circumferential surface of the rotary disc, an active spur gear is arranged on the upper end of the gear ring in a meshed manner, a clamping and conveying device is arranged in the rotary disc, and clamping concave wheels which are symmetrical up and down are arranged in the clamping and conveying device. According to the steel tube surface multi-pattern line spraying device, a steel tube is clamped by the clamping concave wheels on the upper and lower sides, so that the stability of line spraying is ensured; the steel tube is driven by rotation of the clamping concave wheels to be conveyed rightwards, meanwhile, the rotating cavity is selected to be rotated, the clamping concave wheels do continuous or intermittent rotation, and therefore straight lines, spiral lines and circular lines can be sprayed on the surface of the steel tube; and in addition, the rotating speed of the clamping concave wheels is controlled to control the distance between the spiral lines or the circular lines.

Description

technical field [0001] The invention relates to the technical field of surface spraying, in particular to a multi-pattern spraying line device for the surface of steel pipes. Background technique [0002] When producing steel pipes, it is necessary to spray lines on the outer surface of the steel pipes. The traditional steel pipe surface spraying line device is clamped and fixed at both ends of the steel pipes, and the mobile sprayer is used to draw the lines, which takes up a lot of space. At the same time, the clamping of the steel pipes It is relatively inconvenient, the work efficiency is low, and only a single straight line or circular line can be drawn, and the scope of use is small, so that the types of steel pipes that can be produced are less. The present invention illustrates a device capable of solving the above-mentioned problems. Contents of the invention [0003] technical problem: [0004] The traditional steel pipe surface spraying device occupies a large...
