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.

  Although the applicant investigated prior technical documents related to the present invention, the applicant could not find any documents that seem to be particularly similar to the present invention.

  The problem to be solved by the present invention is that when powder particles that have been transported by a feeder are dropped and discharged to a receiver, the density of the dropped and discharged particles becomes high in the portion immediately below the discharge chute. It was very difficult to diffuse evenly in the receptor.

In order to solve the above-mentioned problems, the powder density diffusion device according to the present invention is a vibration receiving material that is a powder particle receiver disposed below a discharge chute of a powder particle feeder that conveys a fixed amount. Between the trough of the feeder and the discharge chute, there is provided a density diffusion member of granular material formed with a curved surface whose diameter is gradually reduced toward the tip direction at least on the upper surface to which the granular material discharged and dropped is applied. It is a density diffusion device for a granular material, and the density diffusion member described above has a right cone shape or a right cone trapezoid shape, and the center line of the density diffusion member is aligned with the center line of the receiver. The density diffusion member described above has a lower bus line installed in parallel with the upper surface of the receiver, and the density diffusion member can be adjusted in the horizontal direction, the front-rear direction, and the vertical direction. The powder feeder is a mounting plate on the lower surface of the casing (11) on which the balance is placed in the density diffusion device for the powder and granular material installed on the balance so that the height position can be adjusted. (12) is provided, and the angle plate (13) is fixed to the lower surface of the housing (11) together with the attachment plate (12) on the lower surface of the mounting plate (12), and is suspended below the angle plate (13). A mounting member having a pair of density diffusion member support flanges (16) is attached to the front surface of the portion by screws from the rear, and a support shaft (7a) is integrally provided on the bottom surface of the density diffusion member. A mounting bar (15) is provided on the support shaft (7a) in a direction perpendicular to the central axis of the support shaft (7a), and left and right portions of the mounting bar (15) are connected to the support flange (16). Fits into the formed long hole or slit It is, up and down, back and forth, by selecting the positions of the left and right are characterized by being fastened with screws.

Moreover, the density diffusion apparatus of the granular material according to the present invention is characterized in that the above-described density diffusion member has a cover on the outer surface, and vibration or rotational force is applied to the above-described density diffusion member. It is characterized by.

Furthermore, in the powder particle density diffusing apparatus according to the present invention, the above-described density diffusing member has a right cone shape, and the lower generatrix is parallel to the trough receiving surface, so that the central axis of the density diffusing member is Is characterized by a slightly downward oblique direction toward the trough direction .

  The granular material density diffusion apparatus according to the present invention is configured as described above. For this reason, when the granular material is discharged and dropped on the upper surface of the density diffusion member of the granular material provided between the discharge chute and the receiver, the granular material hits the density diffusion member, and the density is evenly distributed to the receiver. It will diffuse as substantially uniform. For this reason, it becomes possible to carry out the conveyance by the vibration feeder, which is the next process, and so on.

It is a front view of the whole feeder provided with the density diffusion apparatus of the granular material which implemented this invention. It is a right view. It is a top view.

  This was realized by configuring as illustrated in the drawings and described in the examples.

  Next, an example of a preferred embodiment of the present invention will be described with reference to the drawings. In these drawings, reference numeral 1 denotes a quantitative feeder that conveys a certain amount of the granular material charged into the hopper 2. The feeder 1 is provided with a discharge chute 8 disposed downward in the final stage, and the target granular material is a trough 9 as a receiver of the vibration feeder 4 disposed downward from the discharge chute 8. Is discharged.

  In the figure, reference numeral 10 denotes a reduction gear motor for driving the quantitative feeder 1, and the quantitative feeder 1 is placed on the intermediate weight balance 3 so that the height position can be adjusted. Reference numeral 6 denotes a base of the apparatus. The intermediate weight balance 3 described above is supported via a plurality of support columns 5, 5,..., And the vibration feeder 4 is partially inserted between the support columns 5, 5,. It is installed in a form to put.

  A mounting plate 12 is provided on the lower surface of the housing 11 on which the intermediate weight balance 3 is placed. An angle plate 13 is mounted on the lower surface of the housing 11 together with the mounting plate 12 by a thumbscrew 14 on the lower surface of the mounting plate 12. It is fixed. The angle plate 13 has a mounting member provided with a pair of support flanges 16 for the density diffusion member 7 of granular material attached to the front surface of a portion hanging downward by a thumbscrew 14 from behind.

  The density diffusing member 7 in the present embodiment is formed in a right cone shape, and a support shaft 7a is integrally projected on the bottom surface thereof. At the end of the support shaft 7a, a mounting bar 15 is provided in a direction perpendicular to the central axis of the support shaft 7a. The left and right portions of the mounting bar 15 are formed on the support flanges 16 and 16, respectively. It is fitted in a long hole or slit, and it is attached by selecting the vertical, front / rear and left / right positions. This attachment position is fixed by tightening the thumbscrew 14 from the front side of the support flanges 16 and 16.

  The mounting position of the density diffusing member 7 is between the trough 9 and the discharge chute 8 when the center line along the conveying direction of the trough 9 is aligned directly below the discharge chute 8, and the central axis of the density diffusion member 7 is It matches with the above-mentioned center line of the trough 9. In addition, the bus bar on the lower side of the density diffusion member 7 having a right conical shape is parallel to the receiving surface of the trough 9. That is, the central axis of the density diffusing member 7 is a slightly downward oblique direction toward the trough 9.

  This position setting is because when the central axis of the density diffusing member 7 is parallel to the receiving surface of the trough 9, the density of the powder particles becomes conversely thin at the position immediately below the density diffusing member 7. By setting the position like this, a uniform spraying state can be obtained evenly.

  Moreover, when the above-described density diffusion member 7 has a right conical shape, the degree of diffusion of the granular material increases at a portion having a large diameter, and the degree of diffusion decreases as the diameter decreases. Furthermore, although depending on the characteristics of the target granular material, a rebound phenomenon occurs when it falls and collides with the density diffusion member 7. This rebound is also affected by the hardness of the material of the density diffusion member 7. Accordingly, the material, height position, left and right, and front and rear positional relationships of the density diffusing member 7 can be adjusted by the mounting structure.

  Furthermore, since adhesion to the density diffusion member 7 may occur depending on the characteristics of the granular material, in such a case, it is possible to attach a cover made of a material having low adhesion and corrosion properties to the surface. In addition, the density diffusing member 7 itself can be given a vibration, or can be rotated as necessary. Furthermore, the density diffusing member 7 itself can be formed of a mesh material, It is also possible to impart rotation.

  The density diffusion apparatus of the granular material according to the present embodiment is configured as described above.
