Description

Wire reinforced composite pipe production line and winding machine

Technical Field

The utility model relates to a compound pipeline production facility specifically relates to a compound tubular product production line of silk material reinforcing. Furthermore, the utility model discloses still relate to a coiler.

Background

In the production of steel wire reinforced composite plastic pipes, steel wires are usually wound around a plastic core tube to form a reinforcing layer in the form of a mesh skeleton. And uniformly winding the steel wires on the wire disc on the surface of the core pipe by using a winding machine to form a reinforcing layer as the core pipe continuously advances along the axial direction. Further, an adhesive is applied to the outer surface of the reinforcing layer by means of a subsequent extruder or the like, so as to bond the plastic to form the outer tube.

The winding quality of the steel wire on the core tube has important influence on the quality of the formed composite pipe. For example, if the steel wires are not uniformly distributed on the core tube, the density of the steel wire material at each position of the composite tube is different, which causes the problems of weak pressure bearing capacity of partial area of the pipeline, easy tearing of the pipeline, oil leakage and the like in the using process. Therefore, the stable and uniform implementation of the steel wire winding step has important significance for guaranteeing the quality of the steel wire reinforced composite plastic pipe. Wherein, make the steel wire that is twined keep appropriate tension at the winding in-process to twine on the core pipe with appropriate winding angle, just can avoid the steel wire interval to change when follow-up passing through the mould, ensure the compressive property of fashioned composite pipe.

For this reason, on one hand, the existing winding machine generates an acting force which hinders the wire unwinding of the wire reel at the wire unwinding shaft where the wire reel is installed, so that the steel wire needs to overcome a certain resistance and have a moderate tension when being released from the wire reel; on the other hand, stable winding can be performed at a predetermined winding angle by providing a wire ring, a wire guide head, or the like on the extending path of the wire from the wire reel to the outer peripheral surface of the core tube to change the extending direction. Because the radial position of the wire disc relative to the axis of the core tube is on the circumference with larger radial size than the outer circumferential surface of the core tube, the radial size of each wire guide ring is gradually reduced along the direction from the main rotary disc with the winding angle to the outlet tube end, so that the extension path of the steel wire is prevented from being complicated. The wire guide rings are mainly used for guiding the steel wires to gradually gather towards the outer peripheral surface of the core pipe without generating obvious influence on the tension of the steel wires. Thus, before starting the operation, the position of the wire loop is fixed and is usually not adjusted.

The core tube formed by core tube forming equipment such as a core tube extruder and a core tube extrusion die penetrates through the winding machine along the horizontal direction and moves in the axial direction, and as a main rotary disc of the winding machine rotates around the core tube, steel wires on the core tube are gradually released and wound on the periphery of the core tube to form a reinforcing layer on the periphery of the core tube. In the present invention, for the sake of clarity, the structure of each component is mainly based on the axis of the core tube, and for example, the outer radius of the first wire ring refers to the radius of the circumference around the core tube axis, which is formed by the outer contour of the first wire ring, and the axial direction refers to the direction parallel to the straight line where the core tube axis is located.

Referring to fig. 1 to 5, a filament guiding device for use in a filament reinforced composite pipe production line according to a preferred embodiment of the present invention is provided on a winding machine, and is capable of guiding a filament 20, such as a steel wire, to be wound around an outer circumferential surface of a core tube 30 formed by a core tube forming apparatus. Specifically, the guide wire device comprises a first guide wire ring 1 and a second guide wire ring 2 which are coaxially arranged at a distance from each other, and the inner circle radius of the second guide wire ring 2 is smaller than or equal to the outer circle radius of the first guide wire ring 1. The wire material 20 released from the wire reel of the winding machine is sequentially attached to extend through the inner circumferential surface of the second wire ring 2 and the outer circumferential surface of the first wire ring 1, i.e., first passes through the lower side of the second wire ring 2, then passes through the upper side of the first wire ring 1, and is attached to the ring bodies of the first wire ring 1 and the second wire ring 2, and is released to be wound in a tensioned state to the outer periphery of the core tube 30.

It can be understood that, in the production process, in order to avoid the problems of low production efficiency and the like caused by frequent disc replacement, the winding machine is generally provided with a plurality of groups of wire discs on a main rotary disc, wherein a part of the wire material 20 led out from the wire discs is drawn to the outer surface of a core tube 30 to be wound as a wire disc for use; the remaining wire reels are used as spare wire reels and are continuously wound when the wire material 20 on the currently used wire reel is used up. The extension path strength of the wire material 20 of the present invention mainly means the extension path of the wire material 20 to be wound on the core tube 30 from the wire reel to the outer peripheral surface of the core tube 30 when the wire reel is used. As for the wires drawn from the standby wire reel, since they are not necessarily in a tensioned state, and the position of the wire head can be retained at the position of the wire reel or drawn to a position close to the core tube as required, these wires may temporarily not pass through the first wire ring 1 and the second wire ring 2 or not be attached to the wire ring body.
