Abstract
The invention provides a PP-R stabi composite pipe and a split handpiece structure for manufacturing the same, and relates to a pipe and equipment for manufacturing the pipe. The PP-R stabi composite pipe comprises an inner pipe, an inner adhesive layer, an aluminum layer, an outer adhesive layer and outer-layer plastic orderly from the inside to the outside. The inner pipe and the aluminum layer, and the aluminum layer and the outer-layer plastic are all bonded together by coating glue. The outer-layer plastic extruded by the split handpiece structure has even wall thickness, and the outer adhesive layer extruded through vacuum film covering technology can be better bonded with the aluminum layer, so that the manufactured PP-R stabi composite pipe has more stable performance, can be widely applied to a central air-conditioning system, cold and hot water systems and a radiator heating system, and can completely replace the conventional steel pipe and galvanized steel pipe.
Description
Technical field:
The present invention relates to a kind of tubing and the structure of making tubing, particularly a kind of PP-R stable state is covered aluminum pipe and is made the split type handpiece structure equipment of usefulness.
Background technology:
At present; Along with country's " to mould Dai Gang " policy making, PP-R class tubing is more used, but we can find that the PP-R linear expansion coefficient is bigger in the process of using; Distortion is bigger in the open piping system, and do not possess resistance oxygen, anti-ultraviolet function.So introducing Germany technology production PP-R stable state, numerous domestic enterprise covers aluminum pipe; This kind tubing has five-layer structure; But what adopt is that the composite structure head is extruded outer glue and plastic layer, and tubing glue layer that this kind head is produced and outer plastic layer wall unevenness are even.And do not adopt the vacuum film coating technique to extrude outer glue in process of production, cause glue layer well not combine, finally influence pipe performance with aluminium lamination.
Summary of the invention:
Technical problem to be solved by this invention is that the weak point to prior art provides a kind of novel structure to make the more stable PP-R stable state of performance to cover aluminum pipe.
The technical problem that the present invention solves can realize through following technical scheme:
A kind of PP-R stable state is covered aluminum pipe, it is characterized in that: comprise interior pipe, inner glue layer, aluminium lamination, outer glue-line and outer layer plastic from inside to outside successively.Between pipe and the aluminium lamination, all bond together between aluminium lamination and the outer layer plastic in said through the glue coating.
A kind of split type handpiece structure that is used to make PP-R stable state overlay film pipe; It is characterized in that: mainly comprise vacuum structure of film and outer layer plastic extrusion device in the said split type handpiece structure, be installed on the production line of whole piece PP-R stable state overlay film pipe coating glue with extrude in the outer layer plastic operation.
Said vacuum structure of film is made up of the cover of bleeding, bleed cover gland, stripper rubber, glue core, coating head body and gluing mouth mould, and bleeding is set on outside the interior pipe tubing that coats aluminium lamination, is used for the outer air of sealed tube; Have the valve adjusting vacuum that is used to deflate on the outer layer plastic of the said cover of bleeding, seal with stripper rubber at said bleed cover and the interface setting of the tubing cover gland of bleeding; Said front end of bleeding cover is provided with the glue core, and the glue core is with the coating head body outward and is connected as a single entity with mounting flange; Leave the slit between said glue core and the gluing mouth mould and form the gluing mouth, the gel feed of gluing mouth and coating head body lower ending opening is connected, and is used for applying uniformly glue, and gluing mouth mould is fixed on the production line with a fixing orchid.
After evenly having applied glue; Glue and aluminum pipe closely bind; Tubing enters into heat-preservation cylinder along production line, and said heat-preservation cylinder is arranged on the centre of vacuum structure of film and outer layer plastic extrusion device, and with mounting flange with extrude the outer layer plastic device and link together.
Cover outside in said outer layer plastic extrusion device, comprising plug, outside cover core, outside cover mouthful mould and outside cover handpiece body, saidly outer cover plug and be enclosed within the temperature that tubing is used to keep tubing outward, the front end that outside said, covers plug be shaped on step with outside cover core and be connected; The said outer typing that outer ring that core is enclosed within tubing is used for tubing of covering is covered said outside outside the supporting installation of core front end and is covered a mouthful mould, covers core outward and covers outward between mouthful mould and leave the space, and front end formation extrusion is used for the extrusion plastic outer layer plastic; Saidly outer cover plug and the outer end of covering mouthful mould is outward fixed with covering handpiece body outward, outside said, cover on the outer wall of handpiece body perforate and cover import outside forming, end connection extruder, an end and extrusion are connected.The PP-R stable state that the pipeline that comes out from extrusion is finished product is covered aluminum pipe.
The invention has the beneficial effects as follows that the outer layer plastic wall thickness of extruding through the split-type structural head is even; And outer glue extrude with the vacuum film coating technique after can and aluminium lamination better stick together; It is more stable that the PP-R stable state of making is covered the aluminum pipe performance; Can be widely used in central air conditioner system, cold and hot water supply system, the radiator heating system, can replace traditional steel pipe and coating steel pipe fully.
