Description

[Detailed description of the device]

[0001]

[Field of Industrial Application] The present invention relates to a ceramic body glazing nozzle used for glazeing a surface of a ceramic body such as a molded porcelain or porcelain porcelain in a factory for manufacturing porcelain porcelain, porcelain porcelain, etc. is there.

[0002]

2. Description of the Related Art A glazing nozzle for porcelain body conventionally used for glazing a large porcelain body has a tip inside the outer tube 11 whose tip is bent as shown in FIG. Insert the bent glaze tube 12 and insert the outer tube 11
The air supply pipe 13 was welded to the lower part of the. The operator holds this glazed ceramic body nozzle by hand and
The glaze was applied while adjusting the opening of the to control the amount of glaze discharged.

However, in such a conventional ceramic body glazing nozzle, the base of the glaze tube 12 is supported by the outer tube 11, but the tip of the glaze tube 12 is not fixed to the outer tube 1. Therefore, the core of the glaze tube 12 is likely to be displaced, and the amount of air discharged may become non-uniform, resulting in uneven glaze. Further, such a conventional ceramic body glazing nozzle is not suitable for mechanical glazing by a robot or the like because the tip portion is bent for manual work.
Moreover, there is a problem that the structure is complicated and the ejection state of each one changes due to a slight error in manufacturing, and the same one cannot be mass-produced.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems and provides a ceramic body glazing nozzle suitable for mechanically performing uniform and stable glazing on the surface of the ceramic body. It was completed for the purpose.

[0005]

SUMMARY OF THE INVENTION The present invention, which has been made to solve the above-mentioned problems, has a glazed tube penetrating the center of an outer tube having an air supply port at its base, and the tip of the glaze tube is placed at the tip of the outer tube. In addition to facing the outer tube, a pressure equalizing plate with a number of air circulation holes around the tip of the outer tube is attached to support the glaze tube, and a pressure equalizing chamber is formed between the pressure equalizing plate and the air supply port. It is characterized by having done.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the embodiments shown in the drawings. In FIG. 1, 1 is an outer tube made of a straight metal having an inner diameter of, for example, about 10 mm, and 2 is an air supply port provided at the base of the outer tube 1. Reference numeral 3 denotes a metal glaze tube having an inner diameter of, for example, about 7 mm which penetrates through the center of the outer tube 1, and a tip 4 thereof faces a slightly tapered tip of the outer tube 1. The rear end of the glaze tube 3 is projected rearward of the outer tube 1 so that the glaze can be supplied.

In the present invention, a pressure equalizing plate 5 is attached to the inner side of the tip of the outer tube 1 to mechanically support the tip of the glaze tube 3. As shown in FIG. 2, the pressure equalizing plate 5 has a cylindrical shape with a thickness of, for example, about 15 mm, and the glaze tube 3 penetrates through its center hole. Further, the pressure equalizing plate 5 is one in which a large number of air circulation holes 6 are evenly provided around the center hole, and in the embodiment, the diameters of the air circulation holes 6 are 2 mm and the number thereof is 12. As a result of mounting such a pressure equalizing plate 5 near the tip of the outer pipe 1, the compressed air supplied from the air supply port 2 to the inside of the outer pipe 1 has a pressure equalizing plate 5 inside the outer pipe 1 and an air supply port. After entering the pressure equalizing chamber 7 formed between the pressure equalizing plate 2 and the pressure equalizing plate 2, the air is discharged from the tip of the outer tube 1 through the air circulation hole 6 of the pressure equalizing plate 5.

[0008]

The porcelain body glazing nozzle of the present invention thus constructed is used by being attached to an automatic glazing robot or the like. While the compressed air is supplied from the air supply port 2, the glaze is supplied from the glaze pipe 3. Supply. Air supply port 2 to outer tube 1
The air that has entered the inside of the equalizing chamber 7 is once discharged through the air circulation holes 6 of the equalizing plate 5, and the glaze that has flowed out from the tip of the glaze tube 3 is evenly carried by this air flow. It is sprayed and glazed on the surface of the ceramic body.

As described above, since the glazing nozzle of the present invention supports the vicinity of the tip of the glaze tube 3 with the pressure equalizing plate 5, the misalignment of the glaze tube 3 does not occur, and the air is equalized. Since it is evenly discharged through the air circulation holes 6 of the plate 5, it is possible to obtain a uniform and stable spray state. In addition, the glazed ceramic element nozzle of the present invention has a simple structure and can be mass-produced with the same quality.
The whole shape is straight, so it is suitable for being attached to a robot.

[0010]

As described above, according to the present invention, a pressure equalizing plate is attached to the inside of the outer tube near the tip to support the glaze pipe, and a pressure equalizing chamber is provided between the pressure equalizing plate and the air supply port. By forming the glaze, the glaze can be sprayed uniformly and stably, and it is suitable for mechanically glazeing the surface of the ceramic body. Therefore, the present invention has an extremely great practical value as a ceramic body glazing nozzle that solves the conventional problems.
