Description

Detailed Description of the Invention (11) Technical Field of the Invention The present invention relates to a powder removal machine for solid materials, specifically, a dust removal machine that automatically removes dust etc. adhering to the outer surface of solid materials such as special tablets or capsule tablets. The purpose of the present invention is to 1) relate to a dust removal machine for solid materials;

+21 Background of the technology In general, solid products such as tablets or capsules are press-formed using a tablet machine after pulverizing and mixing the raw materials, and then removed, polished, or polished using a powder remover (or polisher). It is done.

One example of such a powder removing machine is based on the original invention (Patent No. 1036290,
(Japanese Patent Publication No. 55-29743), in which an inlet is provided on the lower upper surface of an inclined cylinder, and an outlet is provided on the upper and lower surface, and a mesh cylinder with a guide coil on the inner wall is installed inside the cylinder. A structure is used in which a brush shaft with a rotary brush is rotatably housed in the center of the mesh cylinder, and a powder outlet is provided in the middle of the cylinder. It is effective in removing powder.

(3) Prior art and problems However, among various tablets, for example, those with a rectangular cross section, which are called soft tablets or irregularly shaped tablets,
The problem of insufficient dust removal effect is experienced.

(2) That is, during the powder removal process, soft tablets were scraped with a rotating brush and became thin, and irregularly shaped tablets were experienced to break at the angular portions.

Therefore, we attempted to solve the above problem by shortening the length of the cylindrical body of the powder remover and reducing the brush polishing process, but although it was effective for soft tablets, it was not so effective for irregularly shaped tablets. It has not been effective and the problem has not yet been resolved.

(4) Purpose of the Invention In view of the above-mentioned conventional problems, an object of the present invention is to provide a solid material dusting machine that can be used for tablets or capsules of different quality and shape.

(5) Structure and object of the invention According to the present invention, an inlet is provided on the upper surface of one end of the outer cylinder, an outlet is provided on the lower surface of the other end, and a mesh cloak is provided on the inner wall inside the nuclear outer cylinder. A porous tube made of, for example, stainless steel is rotatably installed inside the porous tube, and a brush shaft with a rotating brush is also rotatably installed in the center of the porous tube, and the porous tube and brush shaft are rotated at an arbitrary rotation speed. This is achieved by providing a powder removal machine for solids, which is equipped with variable speed rotary drive devices separately provided, and a powder outlet is provided on the lower surface of the outer cylinder.
Further, in such a dust removing machine, a guide coil may be provided along the inner wall of the porous cylinder.

(6) Examples of the invention Embodiments of the present invention will be described in detail below with reference to the drawings.

The figure is a cross-sectional view of the main part of the dust removing machine for explaining the embodiment of the present invention. Referring to the figure, an outer cylinder 1 (for example, about 30 cm long and about 15 cm in diameter) is provided with an inlet 25 and an outlet 26.
m) is equipped with a perforated cylinder 4 having a mesh mat 5 arranged on its inner wall, and a ring gear 18 for rotation is provided on the outer periphery of the perforated cylinder 4 at the end on the side of the inlet 25.

In addition, the brush shaft 6 on which the rotating brush 6a is arranged is attached to the front shaft bearing housing 7 and the rear shaft bearing housing 8, which have a built-in hair ring 9.
It is installed in the center of the porous cylinder 4. Note that the rotating brush 6a is formed so that its tip is in contact with the net mat 5.

In the shaft bearing case, II represents the drive shaft, I2 represents the socket, and I3 represents the V ring.

Further, on the lower surface of the outer cylinder I, a dust collection box 20 is provided with a powder outlet 27 having a damper 21 and an air intake adjustment band 22.
will be established.

On the other hand, a driven toothed wheel 10a is disposed on the drive shaft 11 of the brush shaft 6, and below the driven toothed wheel 10a, the intermediate shaft 14 is held via a mounting plate 23 by a bearing housing 15 containing a ball bearing I6. A pinion 17 that interlocks with the driven toothed wheel 10b and the ring gear 18 is attached to the intermediate shaft I4. The above drive device is gear cover 2.
Protected by 4.

The brush shaft 6 and the perforated cylinder 4 are rotated by applying power from variable speed motors (not shown) provided separately to the driven toothed wheels 10a and 10b using, for example, a belt. Note that the respective rotational speeds and relative rotational directions of the porous cylinder 4 and the brush shaft 6 are as follows.
It is selected as appropriate depending on the type of tablet, capsule, or other solid substance.

(5) (4) In the dust removal machine having the above-mentioned structure, the tablets, capsules, or other solid substances inputted from the input port 25 are
After falling into the rotating rotating brush Ba, it is pressed against the net cloak 5 by centrifugal force, and while rotating, it advances in the discharge direction due to the spiral movement of the rotating brush 6a and reaches the discharge port 2.
Discharge from 6. Incidentally, if the powder remover is tilted at this time, it is effective to transfer the solids in the discharge direction.

The dust removed by the rotating brush 6a during the above-mentioned rotation passes through the mesh of the mesh mat 5 and the holes of the perforated tube 4, and is moved to the inlet 25 and exhausted by a suction device (not shown) attached to the end of the exhaust hole 27. From outlet 26 to powder outlet 27
It builds up near the dust collection box 20 due to the airflow flowing in that direction. The collected dust is sucked out from the powder outlet 27 by a dust generator or the like (not shown).

(7) Effects of the Invention As explained in detail above (according to the present invention, since the rotational speed and direction of rotation of the flange and the porous tube can be independently selected, it is possible to adhere to solid objects such as irregularly shaped tablets and soft tablets). The outer cylinder 1 can automatically and continuously remove the dust that has been removed from the solid object (6) without damaging or deforming the object, and the powder adhering to the solid object can be quickly and reliably removed. The interior of the device can be used hygienically at all times, and since the structure is simple, it is easy to manufacture and can be manufactured at low cost.

4. Additional relations The present invention, in addition to rotating the brush shaft 6 as in nuclear power plants, also rotates the porous cylinder 4, and the rotation speed can be arbitrarily selected. Depending on the quality and shape of capsule tablets or other solid materials, for example, for soft solid materials or irregularly shaped tablets, the brush shaft 6 and porous cylinder 4 are rotated in the same direction at different speeds, and the difference in rotational speed is By making use of the smaller size, the force pressed against the inner wall of the porous cylinder 4 can be weakened, and the powder adhering to the solid material can be effectively wiped away without damage or change in shape.

Further, the transfer speed of the solids to the discharge port 26 can be adjusted not only by changing the inclination angle of the powder remover but also by changing the rotation speed of the brush shaft 6.

Furthermore, a guide coil 28 may be provided along the inner wall of the porous cylinder 4 in order to perform the transfer more smoothly. By appropriately selecting the thickness, number of turns, etc. of the guide coil in accordance with the type of object to be conveyed, the application range of the dust removal machine according to the present invention can be widened.

Further, the method of rotating the porous tube 4 is not limited to the interlocking of the ring gear 18 and pinion 17 shown in this embodiment, and other methods may also be used.
