Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cables, in particular the technical field of cable extruder feeders. BACKGROUND

[0002] The insulation layer of the cable core and the sheath of the cable are extruded by an extruder. During production, the material enters the barrel for melting through the feeder. Therefore, the feeder is a conveying part for transmitting the material to the barrel of the extruder. The insulation material and the sheath material are generally granular materials. During production, storage and transportation, the granular materials are inevitably contaminated with dust or metal powder. Once these substances enter the insulation layer or the sheath, the performance of the product will be affected, and certain safety hazards will be caused.

[0003] The existing patent CN208324136U discloses a cable extruder feeder. The feeder removes the impurities on the filter screen by a brush and then removes the impurities on the brush by negative pressure. The whole impurity removal process is relatively complex. In addition, since the filter screen needs to ensure that the granular material can pass through, part of the impurities will still adhere to the granular material and pass through the filter screen. Therefore, the impurity removal effect is poor. SUMMARY

[0004] The purpose of the present application is to solve the problems in the prior art and provide a cable extruder feeder with dust removal function. The feeder can simplify the dust removal process and improve the dust removal effect.

One end of the rotating shaft is connected to a motor fixed outside the distribution box. A plurality of partition plates are fixed on the rotating shaft and located inside the distribution box. The partition plates divide the inside of the distribution box into a plurality of fan-shaped storage areas with the same shape and size. A first connecting pipe is fixed to the top of the distribution box. A feeder barrel is fixed to the top of the first connecting pipe. The first connecting pipe is connected to the feeder barrel and the distribution box. A second connecting pipe is fixed to the bottom of the distribution box. The second connecting pipe is vertically arranged. The bottom of the second connecting pipe is connected to the top of the storage box. The second connecting pipe is connected to the storage box.
