Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an intermittent jet nozzle device for fluid.

In particular, the present invention relates to an intermittent fluid jet nozzle device suitable for cleaning, scraping, etc. of molded parts by utilizing the instantaneous force of fluid jetted from a jet nozzle.

[Prior Art] As a conventional technology for fluid injection or suction nozzles, there is a technology disclosed in pages 1 to 6 of the catalog "Wonder Gun" by the manufacturer Osawa & Kompany as an air gun.

[Problems to be Solved by the Invention] However, the above-mentioned conventional technology only allows air to be injected or sucked, but does not consider the point of ejecting fluid instantaneously to derive and utilize strong instantaneous force. .

Further, in the conventional technique, when fluid is intermittently injected, another fluid device must be used, and no consideration is given to intermittently injecting fluid from the injecting nozzle itself.

The object of the present invention is to solve the problems of the prior art.

To provide an intermittent fluid jetting nozzle device which can obtain a powerful jetting fluid from a jetting nozzle and can intermittently jet the fluid by the jetting nozzle device itself without intervening other fluid equipment.

[Means for Solving the Problems] The object is to support a rotating body having a plurality of blades on the outer periphery inside a sealed housing, and to support a rotary body having a plurality of blades on the outer periphery, and to A fluid passing hole is formed in at least one location that penetrates in the axial direction of the rotating body, and the movement locus of the fluid passing hole moves in the front and rear of the rotating body in the axial direction of the housing as the rotating body rotates. A main flow nozzle and an injection nozzle are provided in alignment with each other, and a pilot nozzle for blowing fluid into the blades of the rotating body is provided in a direction intersecting the main flow nozzle in the housing, and a fluid is supplied to the main flow nozzle and the pilot nozzle. This is achieved by connecting to the source.

[Operation Code] In this system, a rotating body is rotated by blowing fluid from a pilot nozzle toward the blades of the rotating body.

During that time, fluid continues to be injected from one main stream nozzle toward the injection nozzle, but at the position of the main stream nozzle and the injection nozzle,
Unless the fluid passage holes provided in the rotating body match, the fluid is blocked by the rotating body and no fluid is ejected from the injection nozzle.

When the rotating body is rotated by the fluid blown from the pilot nozzle and the fluid passage hole matches the position of the one-stream nozzle and the injection nozzle, the fluid injected from the one-stream nozzle is injected from the injection nozzle through the fluid passage hole.

Therefore, the fluid is injected only when the fluid passage holes provided in the rotating body match with the main stream nozzle and the injection nozzle, so it is possible to obtain a powerful injection fluid, which can be used to spray molded parts. It becomes possible to perform cleaning, deburring, etc.

In addition, in the present invention, fluid is blown into the blades of the rotating body through the pilot nozzle, the rotating body is rotated in one direction, and the fluid passing hole provided therein is moved, and the fluid passing hole is periodically connected to the main stream nozzle and the injection nozzle. Since the fluid is communicated with each other, the fluid can be intermittently jetted by the jet nozzle device itself without using any other fluid equipment.

The injection nozzle device of the above embodiment is operated as follows.
act.

That is, fluid 1, such as air, is supplied from the fluid supply source 10 to the main nozzle 7 and the pilot nozzle 9 through the main pipe 11 and the branch pipe 12 branched from this.

When fluid is supplied to the pilot nozzle 9, the fluid is blown from one direction through the pilot nozzle 9 to the blades 5 of the rotating body 3 supported in the housing 1.
The rotating body 3 is constantly driven to rotate in the directions indicated by arrows in FIGS. 1, 2, and 3.

As shown in FIG.
The fluid is injected from the injection nozzle 8 through the fluid passage hole 6, and this fluid is ejected only while the fluid passage hole 6 overlaps the main flow nozzle 7 and the injection nozzle 8. Therefore, as a result of the fluid being jetted instantaneously, the fluid can be jetted instantaneously with a larger force compared to a type that jets fluid constantly, and the force of the jetting fluid 13 can be used to clean the molded parts. It becomes possible to carry out arranging, etc.

As the rotating body 3 rotates, when the fluid passage hole 6 passes a position where the main nozzle 7 and the injection nozzle 8 overlap, the third
As shown in the figure, the main flow nozzle 7 and the injection nozzle 8 are blocked by the rotating body 3, and the injection of fluid is interrupted.

Furthermore, as the rotating body 3 rotates, the fluid passage hole 6 periodically moves to a position that matches the main flow nozzle 7 and the injection nozzle 8, so that fluid is intermittently injected from the injection nozzle 8 only by this injection nozzle device. can be done.

Note that when a flow rate control valve is provided in the first branch pipe 12, the flow rate of the fluid sent to the pilot nozzle 9 is controlled by this flow rate control valve, thereby controlling the rotational speed of the first rotary body 3 and adjusting the fluid injection interval. It becomes possible to adjust.

Furthermore, by changing the length of the fluid passage hole 6, the time for one injection can be adjusted.
