The invention discloses a plastic particle feeding device for a cable processing extruding machine. The plastic particle feeding device comprises a dehumidification box, a plastic particle buffer bench, a conveying plate, a driving chain, a hopper and a hot-air heater. Two opposite sides of the dehumidification box are respectively provided with a material inlet and a material outlet. The material outlet is located above the material inlet. The driving chain and the conveying plate are inclinedly arranged in the dehumidification box. The conveying plate is connected to the material outlet and the material inlet. The driving chain is provided with a scraper plate. The top of the scraper plate contacts with the conveying plate. In work, the scraper plate of the driving chain cooperates with the conveying plate so that plastic particles are conveyed to the top of the conveying plate, and the plastic particles fall into the hopper and then fall into a material inlet of an extruding machine. The hot-air heater comprises an air-out part, and the air-out part is located in the dehumidification box and obliquely above the driving chain. In plastic particle upward motion along the conveying plate, the air-out part of the hot-air heater is used for dehumidification of plastic particles so that cable production quality is improved, faulty products are avoided and an extruding machine service life is 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, ...
