Technique and equipment for producing reinforcing band

Abstract

The invention relates to a process and a device for manufacturing a reinforcing band. The process comprises the following steps: (1) fiber spindles or steel wires are regularly arranged to be fiber bundles or steel wire bundles by a payoff rack; (2) each fiber bundle or steel wire bundle passes through a tension controller, the tensions and the positions of the fiber bundles or steel wire bundles in row are adjusted and controlled, the tension of the fiber bundles or steel wire bundles is retained under the action of a fiber bundle or steel wire bundle hauling machine, and the fiber bundles and the steel wire bundle are arranged equidistantly; (3) the equidistantly arranged fiber bundles or steel wire bundles are dried by a dryer; (4) an extruder covers a layer of uniform plastic among the equidistantly arranged fiber bundles or steel wire bundles and on the periphery of the equidistantly arranged fiber bundles or steel wire bundles through a plastic extruding mould to form a thin long-strip-shaped plastic covered band; (5) the plastic covered band is cooled for molding through a formation guiding device and a first cooling water tank; (6) the plastic covered band is further cooled and dried for molding by an air cooler; (7) the cooled and dried plastic covered band carries out tension control, so the reinforcing band is obtained; and (8) the reinforcing band is stored, cut and coiled by a band storage coiling device. The process is simple and practical; and the device has simple structure, good controlling performance and stable and reliable operation.

Description

technical field [0001] The invention relates to a production process and equipment for reinforced thermoplastic pipes (referred to as RTP pipes, RTP-Reinforced Thermoplastic Pipes) used in the fields of gas, chemical industry, petroleum, natural gas, mines, buried electric pipes, etc., and belongs to the reinforced tape Innovative technology of production process and equipment. Background technique [0002] The existing disadvantages of making reinforcement tapes wound on thermoplastic pipes are that the production is complicated, the cost is high, and the thickness and width of the reinforcement tapes are generally not controlled, so that the manufactured reinforcement tapes have some defects in the entire length direction. The thickness and width are large in some places, and the thickness and width are small in some places. When these reinforcing tapes are wound on thermoplastic pipes, it will directly affect the production quality of the pipes. Contents of the inventio...
