Abstract:
A resin extruding and cutting apparatus comprising a resin extruding nozzle adapted to extrude a resin material into strands, a cooling unit arranged in the vicinity of the resin extruding nozzle and supported by a base in an inclined state, the cooling unit serving to cool the extruded strands emerging from the resin extruding nozzle using cold water and having a bottom wall for feeding the strands to a downstream end of the cooling unit therealong, a cutting unit arranged in the vicinity of a downstream end of the cooling unit and adapted to cut the cooled strands, emerging from the cooling unit, into small pieces, the cutting unit including a body, a pair of drawing rollers rotatably mounted to the body, a fixed blade fixedly mounted to the body, and a rotating blade rotatably mounted to the body, a conveyor inclinedly arranged at a downstream end of the cutting unit, and a drier arranged at a downstream end of the conveyor to dry the cut small pieces, further comprising:a strand guide unit arranged between the cooling unit and the cutting unit and adapted to guide the strands discharged from the cooling unit between the drawing rollers of the cut unit, the strand guide unit providing a strand guide surface for guiding the stands discharged from the cooling unit to a nip defined between the drawing rollers of the cutting unit; a level adjusting assembly mounted to the cutting unit in such a fashion that a level thereof is adjustable with respect to the cutting unit, the level adjusting assembly hingably supporting the strand guide unit in such a fashion that the strand guide unit is hingable with respect to the cutting unit while being adjustable in level with respect to the cutting unit so that the strand guide surface of the strand guide unit extends from the downstream end of the cooling unit to the nip defined between the drawing rollers; and water guide means for guiding the cold water, used to cool the strands in the cooling unit, to the conveyor so that the guided cold water is used as a flow of water adapted to feed the cut small pieces along the conveyor, wherein the water guide means comprises: an opening formed at a desired portion of a guide plate in the strand guide unit; and a perforated drain plate mounted to the opening and opened to the cutting unit, the drain plate serving to drain the cold water, flowing from the cooling unit along the guide plate, into the cutting unit.
