Description

  The present invention receives the granular material that is discharged from the discharge chute of the feeder that conveys the granular material by a fixed amount and discharges it from the discharge chute, for example, on a receptacle such as a trough or a tray. The present invention relates to a density diffusion apparatus for powder particles for uniformly spreading mass.

  The granular material dropped and discharged from the discharge chute of the quantitative feeder of the granular material may be received by the trough of the vibration feeder as the next process. In this case, the granular material flows like a waterfall from the primary opening edge part of the upper surface opening of the discharge chute and falls onto the trough. The density becomes higher, and then spreads to the surrounding area. This phenomenon becomes more prominent as the diameter of the discharge chute becomes smaller.

  In the state where the density of the above-mentioned granular material is biased, the post-processing is very troublesome and the elaborateness is impaired, and in the previous stage, the meaning of conveying the granular material precisely and quantitatively is diminished. It becomes a thing.

  Therefore, the present applicant has disclosed a technique shown as Patent Document 1. However, it is difficult to obtain the density diffusion of the granular material which can be said to be sufficient even with this apparatus, resulting in variations, and lacking in precision and stability.

JP 2013-139321 A

  The problem to be solved by the present invention is that the conventional powder density diffusion device does not provide sufficiently satisfactory sophistication, resulting in variation and lack of stability.

In order to solve the above-described problems, the granular material density diffusing device according to the present invention includes a granular material receptacle disposed below a discharge chute of a granular material feeder that conveys a fixed amount, and A powder particle density diffusion device comprising a powder particle density diffusion member formed between the discharge chute and a curved surface whose diameter is gradually reduced with the upper surface to which the powder particles to be discharged and dropped are directed toward the tip. The density diffusing member is an umbrella-shaped member, and is provided with a fan-shaped plate material formed of a corrugated plate below the front side of the umbrella-shaped member , and the fan-shaped plate material is expanded in the trough of the vibration feeder. In the density diffusion device of the granular material arranged so that the width of the opened leading edge matches the width of the trough, the above-mentioned fan-shaped plate member has rubber support legs below the both ends of the opened leading edge, and The rear end is hung by hanging a fan-shaped plate receiving frame with a hanger. It is characterized in that are tilted towards.

Moreover, the density diffusion apparatus of the granular material according to the present invention is characterized in that the position of the umbrella-shaped member is fixed in a state where the rear side is lowered and the front side is raised .

Furthermore, the powder particle density diffusing apparatus according to the present invention is characterized in that the above-mentioned umbrella-shaped member is fixed to the receiving frame with a hook inside the apex .

  And, under the above-described discharge chute, it is provided with a conical member for restricting directionality by preventing scattering of powder particles falling onto the upper surface of the umbrella-shaped member, The conical member has a shape in which the diameter gradually decreases from the upper opening to the lower opening, and the above-mentioned conical member is rotatable in the horizontal direction around the base end of the mounting member. It is a feature.

  The granular material density diffusion apparatus according to the present invention is configured as described above. Therefore, the granular material dropped and discharged from the discharge chute contacts the front upper surface of the umbrella-shaped member and diffused to some extent, but the granular material diffused by the umbrella-shaped member is further scattered on the fan-shaped plate material. As a result, the diffusion of the fan-shaped plate material will spread more widely, and this diffusion work will be stable without variation and the entire trough upper surface can be used efficiently without waste.

  Moreover, since the conical member is provided below the discharge chute so that the position of the conical member can be adjusted, it is possible to freely adjust and adopt the drop discharge directionality of the granular material.

  Furthermore, since the umbrella-shaped member that first receives the fall and discharge of the granular material has the same shape in the 360-degree direction, it is troublesome to examine and check the direction more closely at the time of installation than the conventional conical member. It becomes possible to arrange without.
