Abstract: A device for changing a wire netting in a filter device for synthetic resins comprising a die body fixed in contact with an extruding port of an extruding machine, the die body having a first hole for change drilled therein, a guide inlet communicating with the first hole for change and an extruding port, a pair of second holes for screening drilled in the die body respectively at both sides of the hole for change, a pair of guiding pipes respectively communicating with the pair of second holes for screening, a pair of exhaust guide ways respectively communicating with the pair of second holes, a pair of valve guide ways respectively having a larger diameter than those of the pair of exhaust guide ways and respectively communicating with the pair of exhaust guide ways and an exhaust port, one end of which is opened and the other end of which communicates with the center and connecting portion of the pair of valve guide ways, a valve for changing flow which has a guide opening through which the guide inlet com

Abstract: A foreign material removing device in a synthetic resin reclaiming machine including an extruder having a screw shaft, a filter cylinder connected to the extruder, a resin filter mounted within the filter cylinder so as to form a resin chamber therebetween, a scraper shaft positioned within the filter cylinder and including projected strips as scraper which protrude aslant to the axis of the scraper shaft such that the strips contact the inner surface of the filter and interconnect with the screw shaft, a body fixed to the filter cylinder which includes a first guide hole, one end thereof being connected to the inside of the filter cylinder, an ejecting port, and a second guide hole disposed in an orthogonal direction with respect to the axis of the scraper so as to connect the first guide hole to the foreign material ejecting port further including a plurality of resin passages communicating with the resin chamber, a plurality of dies fixed to the body which include connecting passages for ejecting resin and

Abstract: A device for dealing with chips and cut ends during the processing of plastics and synthetic resins, comprising a feeding chamber having a front chamber and a rear chamber, the front chamber having a circular portion and the rear chamber having a circularly shaped portion at the central part thereof, the upper portion of the feeding chamber having a feeding inlet. A cutting blade is fixed on the center line of the feeding chamber at the upper end of the circular portion of the front chamber, and a rotary shaft is mounted horizontally on the center line of the circular portion of the front chamber and the circularly shaped portion of the rear chamber. A plurality of wheel blades is fixedly separated on the rotary shaft, and a plurality of stopping materials is positioned respectively between the plurality of wheel blades, the lower portions of the plurality of stopping materials being fixed respectively at the lower portion of the rear chamber.
