PROBLEM TO BE SOLVED: To provide a strand delivery apparatus for a strand cutter which does not hamper the rotation of the upper delivery roller in cutting a strand and prevents an uncontrolled movement of the strand. SOLUTION: The strand delivery apparatus 20 cuts a strand inserted from the stationary blade 12 with the stationary blade 12 and the rotary blade 11 installed on the rotating body 10, the stationary blade and the rotary blade facing each other. The top delivery roller 22 rotatably pivoted on the support member 24 and the bottom delivery roller 23 nip and deliver the strand. The jump-up preventive member 30 to prevent the strand from jumping up is installed over the strand before the stationary blade 12 placed in the advance direction of the strand delivered by the rollers 22 and 23. The base end 33 of the arm 31 of the jump-up preventive member 30 is pivoted on the support member 24 coaxially with the rotating shaft 22a of the top delivery roller 22. The arm 31 has the hold-down part 32 to hold down the jump-up of the strand at the tip of it. COPYRIGHT: (C)2007,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a granulating apparatus for forming compost of live stock excreta, foul dropping or the like into granular forms. SOLUTION: A cylindrical basket 9 for receiving the compost 31 to be processed is supported freely rotatively around a vertical fixed shaft 2 and rotated at slow speed by a motor. A roller 16 is vertically supported freely rotatively at a tip of an arm body 13 extended from the fixed shaft 2 to the radial direction in the inside of the cylindrical basket 9. The roller 16 holds a small gap with the inner peripheral surface of the cylindrical basket 9. A guide member 19 for smoothly guiding the compost 31 charged into the cylindrical basket 9 to the push-out roller 16 is further provided. COPYRIGHT: (C)2007,JPO&INPIT
摘要:
A device for the preparation of, preferably thermoplastic, plastics material for recycling purposes has a container ( 1 ) in which at least one rotating mixing and/or comminuting tool ( 14 ) is arranged. The material thus treated is fed through an outlet opening ( 17 ) which is arranged at the bottom of the container ( 1 ) and to which the feed opening ( 18 ) of a housing ( 19 ) is fluidly connected. In this housing are arranged at least two screws ( 21, 22 ) which are jointly charged with material. The diameter (D) of the container ( 1 ) and the diameter (d) of each of the screws ( 21, 22 ) are in the relationship D=10 3 {square root over (d 2 K)}, where D is the inner diameter of the circular cylindrical container ( 1 ) or the inner diameter of a hypothetical circular cylindrical container converted to the same capacity and having the same effective height, d is the screw diameter, and K is a constant greater than or equal to 50.

PROBLEM TO BE SOLVED: To provide a cutter holder and a pelletizer capable of preventing the pellets from remaining in hollow places during the pelletizing operation. SOLUTION: In the cutter holder, in the disk part 11a there is formed the through hole 21 that penetrates from the attaching face 11c side of the side to which the cutter blade 12 is fitted to the shaft side face 11d of the side in which the shaft insert part 11b is installed, and in the shaft insert part 11b there is installed the feed blade 20 which sends a fluid to the direction of the through hole 21 by the rotation of the cutter holder 11 around the cutter shaft 10.

PROBLEM TO BE SOLVED: To provide a method for continuously manufacturing an expandable plastic granular material. SOLUTION: The expandable plastic granular material G can be continuously manufactured by using a method in which a plastic dissolved article F is impregnated by using an expanding agent B and the impregnated dissolved article is made into the granular material. This method is practiced by using an installation comprising at least one pressure forming and feeding apparatus 10 for the dissolved article, especially a volume measuring pump feeding apparatus, a metering apparatus 9 for the expanding agent, a contacting/homogenizing apparatus 2 for impregnating the dissolved article, at least one cooling instrument 3 for the impregnated dissolved article, an underwater granulating machine 6, and an installation controlling part 1.

PROBLEM TO BE SOLVED: To increase output of pellets per hour and to achieve a mass production of pellets having higher quality when they are manufactured by using material having small fluidity. SOLUTION: An extrusion mechanism is provided for mixing a prescribed softened material and extruding it into irregular shapes. A pulverization mechanism is provided for pulverizing the irregular-shaped material extruded from the extrusion mechanism. A shaping mechanism is provided for shaping the material pulverized in the pulverization mechanism into pellets. The irregular-shaped material extruded by the extrusion mechanism is pulverized and then supplied to the shaping mechanism so that the pellets of uniform quality are manufactured. Thereby, high-quality pellets are provided by mass production so as to obtain moldings and aggregates having uniform qualities using the pellets as material. It is easier to make moldings by postforming, and it is possible to further increase output of the pellets per hour. COPYRIGHT: (C)2006,JPO&NCIPI
