る。[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a flow nozzle using a slit for applying a highly viscous coating material with a uniform film thickness. In particular, it is used as a nozzle for easily coating a wide area with an elongated nozzle having the same slit width.

This type of nozzle, called a flow nozzle, flows out the liquid as it is, and in the case of flow nozzles that use elongated slits in particular, the amount of coating material coming out from each position of the outflow slit directly affects the coating thickness. It will have an impact. Therefore, if a uniform coating thickness is required, it is necessary to provide an inlet upstream of the slit over the entire area or to vary the slit width in order to equalize the flow rate at each position of the slit. There is.

In the case of conventional flow nozzles, in order to obtain a uniform flow rate from the slit and form a uniform coating film, it requires a complicated structure or complicated processing such as changing the slit width, which is costly. I had a problem with that. Further, in the case of viscous fluids, particularly high viscosity coating materials, a simple structure of the flow path is required, and a simpler structure is required for removing blockages, cleaning, etc. The object of the present invention is to provide a slit-shaped flow nozzle that has a simpler configuration, simplifies the flow path, and provides a uniform flow rate to the outflow slit.

In order to achieve the above object, the present invention provides a flow nozzle in which an elongated slit is formed in the axial direction on one side of a cylindrical body, and a coating material inlet is provided at approximately the center on the opposite side of the slit. A rectifying rod having a diameter smaller than the inner diameter of the main body is fixed to the approximate center inside the main body by lids provided at both ends of the cylindrical main body, and the cross-sectional shape of the rectifying rod is chevron-shaped on the inlet side, It is approximately fan-shaped with the slit side as the circumferential surface,
And as the ridge line forming the boundary between the mountain-shaped slope and the circumferential surface goes from near the center to both ends,
It is formed so that the chamfered surface gradually becomes larger.

As shown in FIG. 1, the flow nozzle has a coating material inlet 2 formed in the center of a cylindrical main body 1, and an axial slit 3 formed on the opposite side of the inlet 2. The slit 3 is opened leaving both ends open,
Both ends of the main body 1 are fitted with screws 4 and closed with a lid 5. Inside the main body 1, one side of the round bar is formed into a chevron shape to form an inclined surface 7, and the other side is formed into a circumferential surface 1.
1, and a rectifying rod having a substantially fan-shaped cross section is provided parallel to the slit 3. The rectifying rod 8 is arranged approximately at the center of the main body 1 with a gap 13 formed between it and the inner surface of the main body 1, and stoppers 9 provided at both ends of the main body 1 allow the chevron-shaped inclined surface 7 to be connected to the inlet 2. It is fixed to the side. The pins 10 are for ensuring the fixed position, and these are finally fixed and sealed by the lid 5 which is screwed into the screw 4 of the main body 1. Therefore, these stoppers 9, pins 10, and lids 5 are limited to the configuration and shape of this embodiment as long as they fix both ends of the rectifying rod 8 to the above-mentioned positions and close both ends of the cylindrical body 1. There is no need to do so. Further, in the rectifying rod 8, the ridgeline portion 12 that forms the boundary between the chevron-shaped inclined surface 7 and the circumferential surface 11 has a chamfered surface 14 at its corners as it goes from near the center toward both ends. It is formed to gradually increase in size. As a result, the gap 13 with the inner surface of the main body 1 is gradually enlarged. Figures 2 and 3 show the difference in the flow path cross sections. Therefore, when a high-viscosity coating material is fed through the introduction port 2 provided at the center of the main body 1, the coating material passes through the gap between the straightening rod 8 and the inner peripheral surface of the main body 1 and flows out from the slit 3 at the bottom. do.
このとき中央部は導入口２に近いため、隙間を
小さくしてあり、逆に端部に行くにしたがつて、
導入口２より遠く流れの抵抗によつて流出量が減
少するため、隙間を大きくして流出量の低下を防
止している。しかも、整流棒８の導入口側は山形

位置に関係なく、ほぼ均一に保たれるため隙間１
３の変化が十分生かされ、スリツト全体が均一な
流出量に維持される。 At this time, the center part is close to the inlet 2, so the gap is made small, and conversely, as you go to the ends,
Since the outflow amount decreases due to flow resistance farther from the inlet 2, the gap is made larger to prevent the outflow amount from decreasing. Moreover, since the introduction port side of the rectifying rod 8 has a chevron-shaped inclined surface, the resistance up to the gap is kept almost uniform regardless of the axial position.
3 changes are fully utilized and the entire slit maintains a uniform flow rate.

Even with high viscosity coating materials, a uniform flow rate can be obtained and the film thickness after coating can be made uniform. Therefore, the finishing performance of the coating film is improved and the value of the coating is increased. Furthermore, since the nozzle itself has a simplified structure, it is easy to process and handle, and is less likely to become clogged. Even if it becomes clogged with foreign matter, solid matter, etc., it can be easily cleaned.
