Abstract
The utility model provides a vacuum cable sheathing device. The sheathing device comprises a sheathing machine head; sheath material and an extruding die are arranged in the sheathing machine head; one end of the sheathing machine is connected with a machine head evacuation tube; the machine head evacuation tube is connected with an evacuation machine through a connecting pipeline; and an evacuation tube assembly die is arranged at the other end of the machine head evacuation tube. A vacuum device additionally mounted in the sheathing procedure extracts the waste gases accumulated between a sheathing layer and a core wire during the sheathing process, thereby preventing the waste acid gas from corroding the core wire and combining the sheathing layer and the core wire tightly. Therefore, the cable has little possibility to be invaded by moisture; the internal structure of the cable has little possibility to be changed; and the performance index of the cable is ensured to be stable.
Description
Technical field
The utility model belongs to field of cables, relates in particular to a kind of vacuum cable jacket device.
Background technology
When the semi-finished product heart yearn that present traditional cable jacket technology is cable passes through the sheath machine extruder head with certain speed, be extruded into the head position by screw rod after the intensification of solid jacket material (PVC) through the sheath extruder thermal treatment zone, by forming the looped wrap layer on the semi-finished product heart yearn that directly is extruded in cable after the extrusion die moulding, the rapid cooling of the restrictive coating process recirculated water of molten condition is become solid-state by molten condition, thereby finishes the coating of cable jacket.Its shortcoming: 1, the sour gas of the plastics of molten condition (PVC) volatilization is accumulated in and can not get effective elimination between restrictive coating and the heart yearn, can produce long corrosiveness to the heart yearn outer conductor; 2, combine between restrictive coating and the heart yearn loose, cable lay the back in environment very easily at the gap of heart yearn and restrictive coating invasion moisture, cause the decline of cable index, influence useful life.
Summary of the invention
The utility model provides a kind of vacuum cable jacket device, solved corrosiveness that the background technology sour gas produces the heart yearn outer conductor and cable lay the back in environment very easily at the gap of heart yearn and restrictive coating invasion moisture, cause the decline of cable index, influence the shortcoming in useful life.
The technical solution of the utility model is achieved in that a kind of vacuum cable jacket device, comprise the sheath machine head, establish sheath material, extrusion die in the sheath machine head, sheath machine head one end links to each other with the head evacuation tube, and the head evacuation tube is connected with vacuator by connecting tube;
The head evacuation tube other end is established the evacuation tube Go-over mould.
The beneficial effects of the utility model are: the utility model is by installing vacuum plant additional in the sheath operation, take out the waste gas that is accumulated in the sheath process between restrictive coating and heart yearn, thereby avoided of the corrosion of spent acid gas to heart yearn, external sheath layer is combined with heart yearn closely, be difficult for being invaded by moisture, the cable internal structure is difficult for change, guarantees the stable of cable performance index.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Part explanation: 1, head evacuation tube, 2, connecting tube, 3, vacuator, 4, the sheath machine head, 5, the heart yearn semi-finished product, 6, the evacuation tube Go-over mould, 7, sheath material, 8, extrusion die, 9, the sheath product line.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described: a kind of vacuum cable jacket device, comprise sheath machine head 4, establish sheath material 7, extrusion die 8 in the sheath machine head 4, sheath machine head 4 one ends link to each other with head evacuation tube 1, head evacuation tube 1 is connected with vacuator 3 by connecting tube 2, and head evacuation tube 1 other end is established evacuation tube Go-over mould 6.
At the sheath machine head vacuum plant is installed, cable semi-finished product heart yearn 5 enters sheath machine head 4 by evacuation tube Go-over mould 6, head evacuation tube 1, between it, form negative pressure when contacting coating with the sheath material 7 of molten condition, take out waste gas, and make restrictive coating when cladding core wire, form negative pressure restrictive coating closely is coated on the heart yearn, be sheath product line 9 owing to finding time.
Claims (2)
1. vacuum cable jacket device, comprise sheath machine head (4), establish sheath material (7), extrusion die (8) in the sheath machine head (4), it is characterized in that sheath machine head (4) one ends link to each other with head evacuation tube (1), head evacuation tube (1) is connected with vacuator (3) by connecting tube (2).
