Abstract
For a heat sink for cable plastic extrusion machine, comprise discharging opening, described discharging opening outer wall is connected with cooling groove, and cooling groove inwall has some feed tubes, and cooling trench bottom is provided with some supporting plates, and described supporting plate arranges to low order from height in nearly discharge outlet; After the utility model solves the plastics extruding cable sheath, cable temperature is too high and cause the problem of scalding employee, and the utility model is simple and practical, has great market popularization value.
Description
Technical field
The utility model relates to cable production equipment, especially a kind of heat sink for cable plastic extrusion machine.
Background technology
Cable (electric cable; Power cable) cable of at least two stranded similar ropes is normally often organized by several or several groups of wires, often organize mutually insulated between wire, and be often twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.
Extrusion molding is also called extrusion molding in plastic processing, utilizes hydraulic press pressure to claim to extrude in extruding of mould itself in the processing of nonrubber extruder.Refer to that material is by the effect between extruder barrel and screw rod, limit by thermoplastification, while by screw rod pushed forward, continues through head and makes a kind of processing method of various cross section articles or semi-products.
Material enters barrel from hopper, under screw rod turning effort, is fed forward to feeding section, is fed forward is compacted simultaneously at this bulk solids by material tube inner wall and the effect of screw surface fricting shearing; In compression section, spiral groove depth shoals, further compacting, and simultaneously in barrel external heat and screw rod and the effect of material tube inner wall fricting shearing, material temperature raises beginning melting, and compression section is terminated; Homogenizing zone makes material even, and constant temperature, quantitative, level pressure melt extrusion, to head aftershaping, obtain goods through sizing.
Due to after extruding the plastics of cable sheath, cable temperature is too high, easily the problems such as employee's scald occurs.
Summary of the invention
The utility model, in order to solve the technical problem of above-mentioned existence, provides a kind of heat sink for cable plastic extrusion machine.
The technical solution of the utility model is achieved in that
For a heat sink for cable plastic extrusion machine, comprise discharging opening, described discharging opening outer wall is connected with cooling groove, and cooling groove inwall has some feed tubes, and cooling trench bottom is provided with some supporting plates, and described supporting plate arranges to low order from height in nearly discharge outlet.
Cooling liquid is had in described cooling groove.
The supporting plate of the nearly discharge outlet of described cooling groove is on the horizontal line of cooling groove.
Cooling liquid in described cooling groove is running water.
Described cooling groove inside discharging opening supporting plate is farthest immersed in cooling liquid completely.
There is half round cut on described supporting plate top.
After the utility model solves the plastics extruding cable sheath, cable temperature is too high and cause the problem of scalding employee, and the utility model is simple and practical, has great market popularization value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1-discharging opening; 2-lowers the temperature groove; 3-feed tube; 4-supporting plate; 5-cable.
Detailed description of the invention
As shown in Figure 1, the utility model comprises discharging opening, and described discharging opening outer wall is connected with cooling groove, and cooling groove inwall has some feed tubes, and cooling trench bottom is provided with some supporting plates, and described supporting plate arranges to low order from height in nearly discharge outlet; Cooling liquid is had in described cooling groove; The supporting plate of the nearly discharge outlet of described cooling groove is on the horizontal line of cooling groove; Cooling liquid in described cooling groove is running water; Described cooling groove inside discharging opening supporting plate is farthest immersed in cooling liquid completely; There is half round cut on described supporting plate top.
Operation principle of the present utility model is: cable is after discharge outlet is extruded, the plastic cement temperature of cable surface is very high, can not intake at once, its inside can be made to expand with heat and contract with cold cause metal wire to rupture or plastic cement epidermis uneven, therefore cable is held up completely higher than the horizontal line of cooling groove at the supporting plate of nearly discharge outlet, and feed tube is set above cable, feed tube liquid outlet is just to cable, reach initial stage cooling-down effect, then cable is put into cooling liquid top layer gradually along supporting plate, and in the end cable immerses in cooling liquid completely, cable cooling rate is accelerated while not affecting the physical property of cable.
