Abstract

The PE composite pipe production equipment is used for producing a composite pipe which is formed by extrusion molding by using a steel wire as an intermediate layer and plastic as an inner layer and an outer layer. The structure of the device comprises an extruder 1, a machine head 2, a winding machine 3, an oven 4, a composite machine head 5, an extruder 6 and a tractor 7. The winding machine 3 is wound in the same direction by a single or multiple rotary discs 8. The plastic outlet 12 of the compound head 5 is arranged in a throttle-pressurized form. The steel wire 9 coated with the hot melt adhesive 14 is coated, and when the steel wire 9 coated with the hot melt adhesive 14 passes through the oven 4 and the laminating head 5, the hot melt adhesive 14 is melted and bonded with the inner layer plastic pipe 11 and the outer layer plastic pipe 13. The advantages are simple production process, saving raw material, high pressure resistance of pipe, etc.

Description

PE composite pipe production equipment

(1) technical field

It is the intermediate layer with the steel wire that the utility model relates to a kind of production, and ectonexine is plastics, the production equipment of the composite pipe by extrusion molding.

(2) background technology

The PE multiple tube is to be composited by PUR between inside and outside two layers of plastic material, has advantages such as pressure resistance, in the facilities such as the transporting water that is widely used, combustion gas and extraordinary fluid.The steel wire winding method that existing P E composite pipe production equipment adopts is two-way winding, and it is netted to form steel wire.This method is complex process, waste steel wire not only, and twines the rich steel wire that forms and be subjected to easy deformation behind the longitudinal pressure, shortcomings such as voltage endurance capability difference.Secondly, steel wire and inside and outside plastics bonding, thermosol is smeared in existing technology employing between inside and outside plastics way, there is complex process in this method, wastes thermosol, smears deficiencies such as inhomogeneous.In addition, in the coating of outer layer plastic, adopt general and internal layer rely on melt viscosity and the way moulding, exist inside and outside two layers of plastic bonding power poor, easily shortcoming such as separation.

(3) summary of the invention

The purpose of this utility model is to overcome the shortcoming in the above-mentioned technology, proposes a kind of PE composite pipe production equipment, make production technology simpler, economize in raw materials, withstand voltage advantage such as strong.

The utility model is realized by following technical scheme: this PE composite pipe production equipment is made of extruder 1, head 2, wrapping machine 3, baking oven 4, composite machine head 5, extruder 6 and hauling machine 7.Wrapping machine 3 is twined in the same way by single or multiple rotating disks 8.Since the steel wire 9 that twined be monofilament or multifibres in the same way, so only need a wrapping machine 3.One or more steel wires are set on the rotating disk 8 of wrapping machine 3 roll into a ball 10.Like this, technology is simple.Because the steel wire 9 of institute on the inner layer plastic tube that is wrapped in 11 almost is perpendicular to the axial of inner layer plastic tube 11, thus very little in the elastic deformation of pressurized lower edge steel wire 9 directions, increased vertical compressive resistance of inner layer plastic tube 11.

Carry out in the extruding coating process of composite at composite machine head 5 and extruder 6, because throttling supercharging form is arranged in the plastics outlet 12 of composite machine head 5, make the outer layer plastic tube 13 that is coated when contacting, have very big pressure with inner layer plastic tube 11, make inner layer plastic tube 11 and outer layer plastic tube 13 closelyr bonding like this, bonding effect is better.

Smeared PUR 14 on the steel wire 9 that is twined, when the steel wire 9 process baking ovens 4 of having smeared PUR 14 and composite machine head 5, PUR 14 fusings are bonded together with inner layer plastic tube 11, outer layer plastic tube 13, have realized saving the effect of PUR 14.

(5) specific embodiment, accompanying drawings

This PE composite pipe production equipment is made of extruder 1, head 2, wrapping machine 3, baking oven 4, composite machine head 5, extruder 6 and hauling machine 7.Wrapping machine 3 is twined in the same way by single or multiple rotating disks 8.

Plastics outlet 12 axis directions that are arranged on perpendicular to inner layer plastic tube 11 with composite machine head 5.

Smeared PUR 14 on the steel wire 9 that is twined, when the steel wire 9 process baking ovens 4 of having smeared PUR 14 and composite machine head 5, PUR 14 fusings are bonded together with inner layer plastic tube 11, outer layer plastic tube 13.

Claims

A kind of PE composite pipe production equipment, it is made of extruder (1), head (2), wrapping machine (3), baking oven (4), composite machine head (5), extruder (6) and hauling machine (7).It is characterized in that wrapping machine (3) is twined in the same way by single or multiple rotating disks (8).
