A crushing and mixing device includes a mixing vessel in which a plurality of blades installed on a rotary shaft which is rotated by a motor as a driving source and freely rotatably supported, to mix and crush materials. A spiral vane is equipped to supply the materials which are introduced to a rotary shaft corresponding to an inlet from materials, to the mixing vessel; at least two blades are installed on the rotary shaft at an inclined angle; an outlet disposed at a side of a wall of the mixing vessel; the materials are mixed and crushed in the mixing vessel, and an entrained moisture therein is dewatered by the heat generated by actions of shearing, friction and compression; and a molten binder is impregnated in the dehydrated materials.

A friction welding apparatus for joining thermoplastic materials, such as a reinforcing plate to the inner surfaces of oppositely disposed legs of a generally U-shaped workpiece, includes flexible force applying means for applying a force in a direction normal to the direction of relative motion between the parts but in the plane of the mating surfaces for urging the legs of the U-channel into intimate contact with the edges of the reinforcing plate. During a weld time interval the parts undergo relative linear reciprocating motion while being urged in intimate contact by the flexible force applying means which causes the mating surfaces to soften under the influence of friction. After the weld interval, the parts are returned to their original position and are held in forced contact for a time sufficient for the mating surfaces to solidify. Upon solidification the force ceases and the welded parts are removed from the apparatus.

An apparatus for forming depressions in thermoplastic film. The apparatus uses rotating dies to first frictionally heat and soften the film, and to then urge the film into bores in a mold, thereby forming the depressions. The plastic films thus produced are useful in the production of packaging.

A press includes a fixed platen, a vertically movable platen and a double toggle actuating mechanism for raising and lowering the movable platen. A piston cylinder breaks one of the toggle mechanisms, which in turn breaks the second toggle mechanism to raise the platen. A balance mechanism is operatively connected to the movable platen and assists in raising the movable platen and supporting the same in its raised position. A cut piston cylinder is connected to one of the toggle mechanisms.

A plasticizing machine including therein a rotatable plasticizing spinner. The plasticizing spinner includes a working portion which comprises an elongated cylindrical member having a plurality of axially spaced, annular ridges thereon. The working portion is surrounded by a substantially cylindrical housing to define a passage therebetween having a plurality of axially spaced gaps of small radial extent whereby plastic material passing through the gaps is folded and mixed.

A crushing and mixing device and a mixing and melting method attained by the crushing and mixing device having a mixing vessel 3 in which a plurality of blades 10a to 10f are installed on a rotary shaft 5 which is rotated by a motor 8 as a driving source and freely rotatably supported, to mix and crush materials; wherein a spiral vane 12 is equipped to supply the materials which are introduced to a rotary shaft 5 corresponding to an inlet for materials, to the mixing vessel 3; at least two blades of the plurality of blades 10a to 10f are installed on the rotary shaft at an inclined angle which reduces each other's opposing space in the rotating direction; an outlet 17 is disposed at a side of a wall of the mixing vessel to take out the materials when the mixed and crushed material reaches a predetermined state; the materials are mixed and crushed in the mixing vessel 3, and an entrained moisture therein is dewaterd by the heat generated by actions of shearing, friction and compression; and a molten binder is impregnated in the dehydrated materials. This device and method provide methods for utilizing or reusing materials which are problematic for conventional methods in terms of cost and productivity, the materials such as chipped woody waste materials or woody waste materials like pruned branches and leaves of trees, and plant materials and plant-waste materials like stems and leaves of wheat, and are suitable for applications to enhance utilization of wasted materials by improving the filling ratio thereof and to promote reuse of the wasted materials.
摘要:
A plasticizing method uses an apparatus (10) including a barrel (12) having a bore (14) therethrough. An auger (24) and a rotor (30) are positioned in the bore, each extending from opposed ends (16, 18) of the barrel (12) and having ends (26, 34) that are substantially flush. The auger (24) conveys particulate plastic material along the bore (14), the plastic being frictionally melted before passing the auger discharge end (26). The rotor (30) is provided to uniformly heat the melted plastic. Auger (24) and rotor (30) each are associated with independent means for rotating (28, 32) and means for controlling the speed of rotation (50, 52). The speed of rotation of the auger (24) controls the flow rate of plastic through the bore, and the speed of rotation of the rotor (30) controls the temperature of the melted plastic.
