Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a solid powder molding machine.

[Conventional technology]

Conventionally, a solid powder molding machine provided with an inverted conical hopper is known.

[Problems to be solved by the device]

However, the conventional solid powder molding machine has a problem that it is extremely difficult to mold solid powder having a uniform density.

Moreover, when a solid powder cosmetic having a high oil content is produced by such a conventional solid powder molding machine, the uneven cosmetic density causes uneven cosmetic surface or oil oozing out. There was a problem.

That is, there is a problem in that a conventional solid powder molding machine cannot easily produce a high-quality oily solid powder cosmetic.

In order to solve such a conventional problem, the present invention aims to provide a solid powder molding machine capable of molding a solid powder having a uniform density.

[Means for Solving the Problems]

In order to solve the above problems, the solid powder molding machine of the present invention is provided with a hopper having a flat bottom surface and a drop outlet in an eccentric position on the bottom surface. Provided with a stirring means for pushing out the granules, and following the drop take-out port of the hopper, a conducting pipe with a downwardly downward opening is provided below the hopper, and the dropping port of the conducting pipe is at the lower edge of the dropping port of the conducting pipe. A shutter that slidably contacts and moves horizontally in a plane is provided, and the placing means of the container to be filled which can store the powder and granules from the dropping port of the conduit tube and the lower surface of the shutter are freely press-contactable.

The conducting tube may be provided with a vibrator that vibrates the conducting tube.

[Action]

Since the bottom surface of the hopper is flat, the powder particles discharged from the hopper are not subjected to the load of the powder particles remaining in the hopper.

Since the granular material is pushed out to the drop-out port by the stirring means, the discharge amount from the drop-out port becomes almost constant.

A shutter that moves horizontally in a plane is provided at the drop port of the conduit, and the mounting means of the container to be filled and the lower surface of the shutter are provided so that they can be pressed into contact with each other. By placing the placing means under pressure on the lower surface, the powder or granules can be solidified in the container to be filled.

If a vibrator that vibrates the conduit is provided,
The flow velocity of the powder or granules passing through the conduit becomes constant.

Embodiments of the present invention will be described below.

As shown in the cross-sectional views in FIGS. 1 and 2, until the powder particles to be molded into a solid powder are extruded into the pressing step,
The hopper 1 for temporary storage is formed by flattening the bottom surface and opening the upper portion, forming an opening at an eccentric position on the bottom surface, and forming a tubular drop take-out opening 2 with a low upper and lower opening in the opening. Droop.

On the upper surface of the drop-out port 2, a net body (not shown) for selecting the particle size of the powder particles to be dropped is provided. The size of the mesh is 5
40 mesh.

Inside the hopper 1, a stirring means 3 for pushing out the granular material in the direction of the drop take-out port is provided. That is, in this embodiment, a rotary rod 3a having a center point of rotation set immediately above the center point of the bottom of the hopper is provided, and a large number of stirring blades 3b reaching from the rotary rod 3a to the bottom of the hopper are provided around the center of rotation of the hopper 1. Until,
It is suspended at equal intervals, and several stirring blades in it are slidably contactable with the upper surface of the mesh body so that it can be cut.

As the stirring means 3, a brush (brush) may be provided instead of the stirring blade 3a.

Below the hopper 1, a conducting tube 4 through which powder particles fall is provided vertically. The conduit 4 has an intake port 5 facing the drop-out port, opens upward and continues to the drop-out port 2, and a drop port 6 opens downward.

The conducting tube 4 may be connected to the drop outlet 2 by a flexible rubber tube or the like.

A vibrator 7 that vibrates the conduit is provided in the conduit.

A shutter 8 is provided at the lower end of the conducting tube 4 and is slidable on its edge and horizontally movable in a plane. If the peripheral edge portion of the front end of the shutter 8 in the sliding direction is cut obliquely toward the end, the edge of the powder or granular material may be easily cut.

A press plate 9 is provided on the upper surface of the shutter so as to surround the conduit tube 4 and abut on it.

The combination of the hopper 1 provided with the agitating means 3, the conducting tube 4 provided with the vibrator 7, the shutter 8 and the press plate 9 can move up and down freely in the combined set state, and the conducting tube Immediately below the container is the means for placing the container for filling
Provide 10.

The container 10 for placing a container to be filled is a table-shaped bottom die 10a that is sufficiently wider than the cross-section of the conducting tube, and a vertically movable part that slides on the peripheral wall of the bottom die 10a and a part thereof projects from the upper surface of the bottom die 10a. It is formed by including a ring mold 10b. The bottom die 10a has its pedestal 11
A push-up machine 12 is provided below. The top dead center of the ring die 10b is slightly above the bottom dead center of the lower surface of the vertically moving shutter 8 so that it can be pressure-contacted.

The above solid powder molding machine may be used as follows, as shown in FIGS.

As shown in FIG. 3, the hopper 1 and the conducting tube 4 are filled with a powder or granular material. On the other hand, the ring mold 10b is projected from the upper surface of the bottom mold 10a, and a container to be filled 13 having substantially the same volume as that of the recess is placed in a recess formed between the bottom mold 10a and the ring mold 10b without a gap. .

As shown in FIG. 4, the hopper 1 and the set formed by the conducting tube 4, the shutter 8, the press plate 9 and the like are pushed down,
The shutter 8 is opened in the direction of the arrow, and while the rotating rod 3a is being rotated, the powder or granular material is pushed into the container 13 to be filled from the conduit tube 4 to fill the container 13 to be filled with the powder or granular material. At this time, the conducting tube 4 is vibrated by the vibrator 7 to make the falling speed of the powdery particles constant.

Next, as shown in FIG. 5, the lower end of the conduit tube 4 is closed by the shutter 8, the shutter 8 is pushed down together with the press plate 9, the bottom die 10a is pushed up by the push-up machine 12, and the bottom die 10a and the ring die 10b are separated. The powder and granules are solidified in the container 13 to be filled in between.

Then, the shutter 8 is instantly put in and taken out, and the shutter 8
And the powder in the container 13 to be filled are prevented from adhering. Next, as shown in FIG. 6, the shutter 8 and the planned filling container mounting means 10 are separated.

If necessary, it is advisable to perform final mold clamping again in the next step.

In this embodiment, since the press plate 9 surrounding the conduit tube 4 is provided in contact with the upper surface of the shutter 8, the container to be filled 13
The pressing pressure can be made uniform.

Since the net for selecting the particle size of the falling powder particles is provided on the upper surface of the drop take-out port 2, the texture of the solid powder obtained is made more uniform.

In particular, it can be preferably used for solidifying a powder or granular material having a high oil content.

[Effect of device]

Since the present invention has the above-mentioned structure, it is possible to mold a solid powder having almost uniform density.
