Abstract

The invention relates to a production method for a vent wind cone, in particular to a production method for a flexible vent wind cone for a tunnel and a mine, which comprises the following steps: (1)installing equipment: a first extruder, a basement membrane mould, a second extruder and a towing mechanism are sequentially arranged in a production place, wherein two ends of the basement membrane are respectively positioned in the first extruder and the second extruder, and a warp lapping mechanism and a weft lapping mechanism are arranged at the basement membrane mould; (2) extruding the basement membrane: PVC material is extruded from the first extruder to form a basement membrane which is sleeved on the basement membrane mould; (3) lapping reticles: warp lines and weft lines are paved onthe basement membrane; and (4) compounding: the basement membrane with the recticles enters the second extruder through the towing mechanism, and the second extruder extrudes the PVC material which is compounded with the basement membrane to obtain the vent wind crane. The method is formed at one time, has no joint seam and saves labor force and production cost.

Description

(1) Technical field: [0001] The invention relates to a production method of a ventilation cylinder, in particular to a production method of a flexible ventilation cylinder used in tunnels and mines. (two) background technology: [0002] At present, there is an increasing demand for high-strength flexible ventilation ducts in tunnels and mines. The current method of producing high-strength flexible ventilation ducts is: first use high-strength chemical fiber to produce mesh cloth, then compound the mesh cloth with plastic to produce flexible materials, and then process the flexible materials through high-frequency welding. A cylinder is required, that is, a ventilation duct. The method has a long process flow and high production cost, especially the long production process of the mesh cloth and high cost. And the ventilation duct produced by this method has seams, which causes unavoidable waste in raw materials, and its ability to bear strength and pressure is limited. (3...
