Abstract
The utility model provides a heating system of a winding machine for plastic-steel winding pipes. The heating system comprises two heating copper tubes for providing hot air by an industrial air heater, wherein the two heating copper tubes are respectively arranged in a belt straightening area between a forming cage and a belt feeding mechanism and a circular-arc area in the forming cage; a plurality of hot air outlets are uniformly formed on inner side surfaces, towards a belt lapped part, of the two heating copper tubes. The heating system disclosed by the utility model has the advantages that the lapped part of the belt is firstly heated up by hot air uniformly blown out by the heating copper tubes during a process that the belt passes through the belt feeding mechanism to enter the forming cage; after the belt enters the forming cage, the belt is wound to be tubular under combined action of a pressing mechanism and the forming cage, and then the belt lapped part is heated up by the circular-arc heating copper tubes inside the forming cage; after the belt which is heated up at two sides is bonded and pressed by a binding agent extruded from a binding agent extruder, pipes are uniformly heated up and bonding strength at the lapped part is high, so that the winding pipes have good quality.
Description
Technical field
The utility model relates to a kind of plastic-steel spirally-wound pipe moulding cage, particularly a kind of plastic-steel spirally-wound pipe wrapping machine heating system.
Background technology
Polyethylene plastic-steel winding pipe is a kind of Novel non-pressure drainage pipe, it is that to take high density polyethylene (HDPE) (HDPE) or medium density polyethylene (MDPE) plastics and structural carbon steel cold-rolled strip (for example Q195) be raw material, after being processed into composite strip by continuous extrusion way, then through a kind of structural walls drainage pipeline be wound around, Plastic Welding processes.Have that corrosion-resistant, quality is light, simple installation, through-current capacity is large, the life-span is long advantages such as (50 years), the tubing of alternative high energy consumption material (cement, cast iron, pottery etc.) making, genus environment-friendly product.
In the manufacturing process of polyethylene plastic-steel winding pipe, structural carbon steel cold-rolled steel tep reel is arranged on the back shaft of uncoiler, and draws several steel bands from uncoiler.The steel band of drawing is through the flat rubber belting machine, and the steel band after smooth becomes vertical direction by horizontal direction and enters in extruding dies and carry out compound extruded with the vinyon of melting.The unshaped section bar of compound extruded forms continuous band after shaping platform Vacuum shaping and water cooling, the band of moulding continuously enters in wrapping machine, under the synergy of the constraint of moulding cage and laminating mechanism, band is wound in continuous circular tube shaped, is wound around and carries out the whole tubing of bonding formation in lap-joint with adhesive simultaneously.Be wound at band the polyethylene plastic-steel winding pipe that cuts into certain-length in the pipe process by cutting off operation.
When band is wound in continuous circular tube shaped in the moulding cage, need to be to the band preheating, to improve into the adhesive strength between band after pipe, general way is to adopt the hot-air mouth of industrial air heater directly lap-joint's blowing hot-air of band to be heated at present, the shortcoming of this kind of method is: heat inhomogeneous, also can't reach pre-heat effect preferably, affect the quality of connection of band lap-joint.
The utility model content
The technical problems to be solved in the utility model be to provide a kind of can be evenly to the plastic-steel spirally-wound pipe wrapping machine heating system of band lap-joint homogeneous heating.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of plastic-steel spirally-wound pipe wrapping machine heating system, be arranged in the wrapping machine mainly formed by moulding cage, tape-feed, laminating mechanism, binding agent extruder,
It is characterized in that: described heating system comprises two heating copper tube that hot blast is provided by industrial air heater; Two heating copper tube are installed on respectively band flat region and the interior circular arc zone of moulding cage between moulding cage and tape-feed, described heating copper tube adopts respectively the structure with this zone band profiling in band flat region and circular arc zone, and evenly have some hot-blast outlets at the inner surface towards band lap-joint, and leave suitable gap between the lap-joint surface of the medial surface of this heating copper tube and band.
The utility model has the advantage of:
Band enters in the process of moulding cage through tape-feed, and at first its lap-joint is positioned at this regional heating copper tube and evenly blows out Hot-blast Heating; After band enters the moulding cage, under the acting in conjunction of laminating mechanism and moulding cage, straight strip coil is coiled into to tubulose, again by circular arc heating copper tube in the moulding cage to band lap-joint homogeneous heating again, after the binding agent from extruding the binding agent extruder carries out bonding, pressing, form complete tubing through the band of both sides heating.Adopt the band that in the utility model, heating system is heated, homogeneous heating, lap-joint's adhesion strength is high, makes winding pipe have good quality.
The accompanying drawing explanation
Fig. 1 is plastic-steel spirally-wound pipe wrapping machine structural representation of the present utility model.
Fig. 2 is the heating copper tube structural representation that is positioned at moulding cage circular arc zone in the utility model.
The specific embodiment
As shown in Figure 1, 2, wrapping machine mainly comprises moulding cage 1, laminating mechanism 2, binding agent extruder 3, tape-feed 4 and heating system.
Moulding cage 1 by a pair of adradialia and between the array format roll form, the array format roll forms a bottom tool annular jaggy, indentation, there is the band feed side.
Tape-feed 4 is positioned at the band feed side dead ahead of moulding cage 1, and it is comprised of three groups of rubber concora crush rollers and grooved roller.
Binding agent extruder 3 is arranged on the top of tape-feed 4, and the extruder head of extruder is positioned at moulding cage 1, over against the lap-joint of band.
Laminating mechanism 2 is arranged in moulding cage 1, its press bonding roller coordinates straight band is wound in to tubulose with the format roll of moulding cage 1, simultaneously, also for two adhesive surfaces of the band lap-joint to having applied binding agent, carry out roll extrusion, to strengthen the adhesive strength between the band adhesive surface.
Heating system comprises two heating copper tube 5,6 that hot blast is provided by industrial air heater; Two heating copper tube 5,6 are installed on respectively band flat region and the interior circular arc zone of moulding cage 1 between moulding cage 1 and tape-feed 4.
Heating copper tube 5,6 adopts respectively the structure with this zone band profiling in band flat region and circular arc zone, heating copper tube 5 is flat construction, and heating copper tube 6 is arc.
Heating copper tube 5,6 evenly has some hot-blast outlets 7 at the inner surface towards band lap-joint, for hot blast can be blown out smoothly, between the medial surface of heating copper tube 5,6 and the lap-joint surface of band, leaves suitable gap.
