Description
Technical field
The utility model belongs to cable processing technique field, specially a kind of inner sheath extrusion moulding apparatus for cable.
Background technique
Wire and cable is to transmit electric power, transmitting information and realize that major class electrician's wire rod of electromagnetic energy conversion produces
Product.The primary structure of wire and cable includes conductor, insulation and sheath；Wherein specific sheath is again according to the building ring of wire and cable
Border requires, and is divided into the different sheaths such as inner sheath, armouring and oversheath.
Wire and cable production is the product produced using the manufacturing method coated layer by layer, is covered by the portion of internal layer
Point, it will be difficult to it checks and exchanges；Therefore it is required that must complete to process according to the structural order of product in technique, and pass through optimization
Process equipment and structure are further ensured that the quality of material；And in this link of sheath, common processing sequence is from inside to outside
For " inner sheath-armouring-oversheath ".
The plastic sheath of cable is carried out using continuously extruded mode.Extrusion equipment is single screw extrusion machine.It squeezed out
Journey is the same as insulating exruded；And in the process of cable cover(ing), there is the case where charging direction is fixed and is arranged at one end, to lead
Core model uneven heating is caused, there is situations such as size unevenness caused by overheating and crackle in cable sheath side after molding, and
It is also that current cable processes a big blank field for the pre-heating drying before cable cover(ing) extrusion molding.
Utility model content
The purpose of this utility model be in view of the above problems, provide a kind of inner sheath extrusion moulding apparatus for cable, it
Stomata generation can be effectively prevented to pre-heating drying is carried out before sheath extrusion molding；And pass through the dry link that uniformly cools down with feeding
It works in coordination, when efficiently utilizing thermal energy and avoiding extrusion molding the case where the uneven heating of unilateral side.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of inner sheath extrusion molding for cable
Device, it includes inner sheath extrusion molding die body, and the inner sheath extrusion molding die body rear and front end is respectively arranged with incoming line and line outlet；
The inner sheath extrusion molding die body front is provided with inner sheath extrusion molding hot-air drying device, the inner sheath extrusion molding hot-air drying device
Rear is provided with inner restrictive coating feed pipe；In the inner sheath feed pipe and inner sheath extrusion molding hot-air drying device are provided centrally with
Sheath core model；Passing through in the inner sheath core model has cable；Inner sheath core model front end is provided with inner sheath extrusion die；
Air outlet is provided in the inner sheath extrusion molding hot-air drying device, and the corresponding position of inner sheath core model is provided with inner sheath
Preheating and drying mouth.
Further, the air outlet and inner sheath preheating and drying mouth direction are tilted towards incoming line side.
Further, the tilt angle of the air outlet and inner sheath preheating and drying mouth is 45 °.
Further, heat-conducting layer is provided between the inner sheath extrusion molding hot-air drying device and inner restrictive coating feed pipe.
Further, inner restrictive coating feed pipe front is bent, and the inlet and outlet of inner sheath feed pipe are not directly opposite.
The utility model has the beneficial effects that the utility model is by inner sheath extrusion molding hot-air drying device and inner restrictive coating feeding
Pipe is sticked together by the way that heat-conducting layer is arranged, can use material it is uniformly distributed in feed pipe while, effectively utilize its heat and produce
Heat wind；The hot wind generated simultaneously can be moulded the hot wind that steam is had after drying to inner restrictive coating due to the angle of air outlet
The opposite direction in shape area is blown away, the generation of stomata when avoiding extrusion molding.
The utility model can dry cable core, prevent the effect due to moisture (or moisture of wrapped bed course) from making to go out in sheath
The possibility of existing stomata.By preheating and drying can also prevent squeeze out in plastics because quenching remain in pressure effect.In extrusion molding material
In the process, preheating can eliminate cold line and enter high temperature head, and the greatly different temperature difference formed when contacting at die orifice with plastic cement avoids plastics
The fluctuation of temperature and the fluctuation for leading to extrusion pressure, so that steady extruding amount, guarantees to squeeze out quality.
