Beam tube production line for mine

Abstract

The invention discloses a beam tube production line for mine, and belongs to the technical field of productive mines. The beam tube production line comprises a monotube extruder, a cooling water box and a beam tube wrapping machine, wherein a core model of the monotube extruder is a cone from a discharge end to a feed end; a first feeding cavity formed between the core model and a port model gradually reduces from the feed end to the discharge end; a vacuum water box on the front end of the water box is internally provided with a tubular molding, and the tube wall of the tubular molding is provided with a water-penetrating groove; the beam tube wrapping machine comprises a feed pipe and a wrapping mould, wherein the outer wall of an inner mould in the wrapping mould is provided with a feeding groove, and the feed pipe is communicated with the feeding groove; and a second feeding cavity formed between an outer mould and the inner mould begins to gradually increase form a feed pipe side to the other side. The beam tube production line increases discharge pressure of the first feeding cavity, and the production efficiency is promoted; the added vacuum water box prevents a single tube from transforming, and the cooling speed of the single tube is accelerated; and the second feeding cavity realizes uniform discharge, and avoids a phenomenon that the wall thickness in manufacture is not uniform and is easy to crease.

Description

technical field [0001] The invention belongs to the technical field of mine bundle tube manufacturing, and in particular relates to a mine bundle tube production line. Background technique [0002] In recent years, with the enhancement of mine safety awareness, the fire spontaneous combustion bundle tube monitoring system has gradually been widely used in the coal industry. Under the control of the control cabinet, the gas circuit is automatically switched through the control cabinet to detect the sample gas, and the possible risk of spontaneous combustion and explosion is analyzed through the gas change trend diagram and the principle of triangular explosion analysis, so as to realize the early warning of spontaneous combustion and explosion in underground fires and avoid accidents. This requires a large number of anti-combustion and anti-static polyethylene bundle pipes for coal mines, which will bring market opportunities to the production of bundle pipes. [0003] At pr...

AI Technical Summary

Problems solved by technology

In the process of forming a single tube, there are often problems such as uneven thickness, uneven wall thickness, and broken wires in the middle. When multiple single tubes are combined into a bundle tube, uneven coating will easily cause uneven thickness after the bundle tube is formed. , the outer layer of polyethylene cladding bulges, voids and other phenomena seriously restrict the production quality of mine bundle tubes, and only four meters of single tubes can be produced per minute, and the productivity is low
