Description

Technical Field

[0001] The utility model relates to a feeding device, in particular to a storage component and a feeding device. Background Art

[0002] Crosslinked polyethylene (XLPE) is a raw material used for preparing the insulating layer of cables, and has advantages such as good heat resistance and good corrosion resistance.

[0003] In the case where the temperature difference in four seasons is relatively large, such as in the coldest months of winter, the relevant crosslinked polyethylene raw materials are prone to have a temperature difference. Since the relevant crosslinked polyethylene raw materials will absorb a large amount of heat when entering the extruder to ensure the plasticization of the raw materials, and due to the easy existence of temperature differences in the relevant crosslinked polyethylene raw materials, it is easy to change the plasticization position of the raw materials in the extruder, resulting in unstable discharge amount during extrusion, and ultimately leading to large fluctuations in the thickness of the insulating layer of the cable.

[0031] Specifically, during operation, the hot air generated by the relevant hot air supply assembly 4 enters the air duct 15 through a plurality of air inlets 13. A part of the hot air flows through the entire air duct 15, flows through the top of the relevant cross-linked polyethylene raw material and finally discharges from the air return outlet 14, which is convenient for heating the outside of the relevant cross-linked polyethylene raw material. Another part of the hot air sequentially flows through the inner cavity 34 and a plurality of ventilation openings 35, then flows through the inside of the relevant cross-linked polyethylene raw material and finally discharges from the air return outlet 14, which is convenient for heating the inside of the relevant cross-linked polyethylene raw material; In summary, the storage component of the present application is convenient for heating both the outside and the inside of the relevant cross-linked polyethylene raw material, thereby facilitating the reduction of the temperature difference of the relevant cross-linked polyethylene raw material, and further not easily changing the plasticization position of the raw material in the extruder 5, ensuring a stable discharge amount during extrusion, and finally ensuring that the thickness fluctuation of the insulating layer of the cable is small.
