Description

[Detailed Description of the Invention] (Purpose) The present invention relates to a powder coating machine, and its purpose is to provide an improved coating pattern adjustment tool that is installed in the front part of the paint discharge port of the powder coating machine to adjust the direction of paint discharge. It is in.

(Prior Art) As shown in Fig. 1, in a powder coating machine, a coating pattern adjusting tool 3 is provided at the front of a paint discharge port 2 of a coating machine body 1.

The paint pattern adjustment tool 3 is provided to adjust the direction of paint discharged from the paint discharge port 2. This prevents the paint from traveling straight and directs the paint toward the object to be coated with a certain spread. I will move on.

The coating pattern adjustment tool 3 is fixed to an adjustment rod 4, and can be moved closer to or away from the object to be coated by adjusting the adjustment rod, and tools of various diameters can be used. Therefore, by performing these operations, it is possible to obtain the optimum coating pattern for the object to be coated.

Conventionally, as the coating pattern adjusting tool 3, a tool made of polyacetal resin and having a planar tip end as shown in a front view a and a side sectional view b in FIG. 2 has been used.

When painting is performed using the paint pattern adjuster 3 made of such a material and shape, the paint adheres and accumulates on the tip surface of the paint pattern adjuster 3, and when a certain amount is reached, it forms a block shape. It adheres to the object to be coated and causes poor appearance of the painted object.

The phenomenon of defects as described above tends to occur very frequently depending on static voltage, paint discharge amount, air volume pressure, weather conditions, physical properties of paint, etc., and has become a big problem in powder coating work. .

The present invention was created as a result of intensive studies to solve the problems in view of the current situation as described above.

(Structure) In other words, the present invention is a coating pattern adjustment tool for a powder coating machine, which is provided in the front part of the paint discharge port and has a cup-shaped tip with a sharp end surface for adjusting the paint discharge direction. The details are as described below based on the examples.

FIG. 3 is a side cross-sectional view (b) and a front view (a) showing an embodiment of the present invention. In this embodiment, the tip is hollowed out into a conical shape and has a tupular shape with a sharp end surface.

If the tip is shaped like a cup with a sharp end surface in this way, there is no paint adhesion surface on the tip surface, so the paint does not adhere to this area at all, and the paint forms blocks and adheres to the object being coated. The phenomenon no longer occurs. Furthermore, as shown in FIG. 3, a plurality of through holes 5 extending from the inner wall surface to the outer wall surface of the tip portion were provided at appropriate intervals, and the effect was further improved.

We also investigated various materials for forming the paint pattern adjustment tool, and the results showed that the use of Teflon resin was most effective.

(Effects) In conventional powder coating work, the paint deposited on the tip of the paint pattern adjustment tool becomes blocks and adheres to the object to be coated, resulting in poor appearance, which requires a large amount of man-hours to correct. Of course,
In order to prevent this defect from occurring, it has been necessary for the operator to shake off the paint deposited on the tip of the paint pattern adjusting tool by shaking the paint sprayer from time to time.

This type of work that shakes off paint by applying vibrations to the painting machine causes extra man-hours for the worker, can lead to damage to the painting machine, and is a major hindrance in efforts to fully automate painting work. Ta.

However, when painting was carried out using the painting pattern adjusting tool of the present invention, all of the above-mentioned problems were solved, and a very large effect was brought about on the painting work.
