The invention discloses a plastic particle supplying device of a plastic extruding machine. The plastic particle supplying device comprises a material feeding barrel, a negative-pressure feeding mechanism and a dehumidification device, wherein the dehumidification device is positioned below the material feeding barrel and above a material inlet of the plastic extruding machine, and comprises a plastic particle circulating body and a hot air device, the hot air device is installed on one vertical side surface of the plastic particle circulating body, and the side surface, provided with the hot air device, of the plastic particle circulating body and the opposite side surface are ventilated. According to the technical scheme, firstly, a material falling hole of the material feeding barrel is sealed, the negative-pressure feeding mechanism feeds the materials to the material feeding barrel, then the material falling hole of the material feeding barrel is opened, and plastic particles fall into the plastic particle circulating body through the material falling hole; the hot air device is used for pouring hot air to the plastic particles in the plastic particle circulating body, and the plastic particles are dehumidified. The dehumidified plastic particles enter the plastic extruding machine so as to produce a cable, thus not only can the quality of the cable be improved, the production of defective products can be avoided, but also the service life of the plastic extruding machine can be prolonged.
Description
technical field [0001] The present invention relates to cable manufacturing equipment, in particular to a plastic granule feeding device for an extruder for cable processing. Background technique [0002] Extruder is one of the cable processing equipment. According to the flow direction of the head and the angle between the centerline of the screw, the extruder can divide the head into a right-angle head and an oblique head. The shell of the machine head is generally fixed on the fuselage with bolts. The mold inside the machine head contains a core seat, which is then fixed to the inlet port of the machine head with a nut. The core seat is also equipped with a The mold core, and the center of the mold core and the mold core seat have holes, which are used to pass the core wire. According to the different types of pressurization, the extrusion process can be divided into continuous extrusion and intermittent extrusion. The equipment used in the former is a screw extruder, ...
