A drying apparatus under reduced pressure for a plastic molding material. The apparatus comprises a drying hopper provided with an airtight material charge valve capable of containing gas therein at its upper portion and a material discharge valve at its lower portion, and connected to a vacuum pump via vacuum piping, a heating means of thermal conduction type provided in the drying hopper, and a plastic material adherence preventing means in which a gas charge port connected to a gas tank storing gas via a gas changeover valve is provided between the material discharge valve and the drying hopper and stored gas is fed into the drying hopper by opening the gas changeover valve after predetermined time, thereby preventing adherence of plastic molding material.

When the rocking side wall is to be opened, the rocking side wall is rotated about a shaft body and a cutout surface comes into contact with a side surface on the upper side of a connection plate When the rocking side wall is further opened with the cutout surface in contact with the side surface on the upper side of the connection plate, the rocking side wall is rotated about the shaft body in operative association with the connection plate. In the middle of the opening motion of the rocking side wall, a rocking axis of the rocking side wall moves from the shaft body to the shaft body. When the rocking side wall is rotated about the shaft body placed closer to the outside than the shaft body, the rocking side wall is opened while being further away from rough crush blades and the crush blades, and this widen the opening between the rocking side walls.

Powder-particle material in compression molding is transferred using air suction power and filled thinly, evenly and rapidly in a female mold. An adsorption padwhich is held so as to be freely movable in the vertical direction is provided at a movable cylinder, which can move in the horizontal direction in a space between a metal supply hopperand a female moldand rotate 180&#xb0;, and powder particle material is laid in a scraped manner at the adsorption pad, adsorbed by actuating a vacuum pump, transferred to the female moldin this state, turned around and caused to fall into the mold by terminating adsorption.

A screw type material feeding apparatus in which a screw rotary driving axis with a spiral material supply blade is rotatably contained in a material feeding tube. The apparatus comprises a material divider with plural vanes provided at the distal end of the rotary driving axis, the plural vanes radially project from the screw rotary driving axis.

A powder body metering apparatus for metering a powder body such as a synthetic resin raw material is structured such that a powder body outlet of a metering container of another metering apparatus is connected to a second opening (), whereby a powder body transport system is constructed, the powder body within the metering container of the other metering apparatus can be transported to a predetermined place via a metering container (), by finishing a discharge of the powder body within the metering container (), thereafter keeping a switch valve () in a closed state, filling the powder body in the metering container of the other metering apparatus and thereafter generating a gas stream toward a first opening () from the second opening (), thus the metering container () being utilized as a part of a transport pipe.

Powder and granular material metering device

In a powder body metering apparatus for metering a powder body such as a synthetic resin raw material or the like, a powder body discharge port () is formed in a lower portion of a metering container () of a metering apparatus () and is freely opened and closed by a case () provided with a porous body (), the powder body metered by the metering container () is discharged from the powder body discharge port () of a lower tube () by horizontally oscillating the case () so as to open the powder body discharge port (), whereby it is possible to easily meter and confirm a weight or the like of the powder body metered by the metering container ().

A weight measuring apparatus housing therein a load cell for measuring the weight of material stored in a material storage tank in which the tank has a material feeding opening. The tank includes a shoulder frame fixed to only the tank and a support arm penetrating through the tank so as not to contact the tank and firmly supported at its both ends at the outward of the tank, and a load cell provided so as to be directly supported between the shoulder frame and the support arm.

Apparatus for measuring weight of powdered and granular materials

A method of mixing pulverulent materials and a device for practicing the method. In this method, the pulverulent material constituting a main material is continuously fed to a conveyor duct connected to a molding machine in fixed quantities while air is being fed to under pressure or drawn from the duct and simultaneously the pulverulent material constituting compounding ingredient material is fed to the duct at a specified value so that a mixing ration is maintained at a specified value. And in the method, a mixing ratio is changeable by variably controlling the amount of supply of compounding ingredient to the main material while feeding air into the duct or drawing air from the duct. In addition, the device is constructed of a pneumatic closed loop duct type and comprises a closed looplike duct, a pulverized reclaimed material feed unit, a virgin material feed unit, and a control means for regulate a mixed ratio.
