Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a nozzle for a hot air welding machine for bonding work, which is effective when bonding synthetic resin sheets.

[Prior art and its problems]

Currently, waterproof floors in kitchens, laboratories, etc. are constructed using the following two methods.

That is, one method is as shown in FIG. 4a,
Attach synthetic resin sheet flooring B to floor A, and attach L-shaped synthetic resin baseboards to the corners of wall C and the floor, and weld welded wire made of synthetic resin to the butt parts. Another method is to spread the flooring material all over the floor surface and adhere it, as shown in Figure b. In this method, a baseboard is placed on top of the baseboard, and the side edges of the baseboard and the flooring material are melted using a welding wire hodget heater to bond them together.

Both waterproofing construction methods require welded wire rods,
It was difficult to work with, and at the same time, marks from the welded parts remained, which caused problems with the finish.

This problem can be solved if the floor abutting part X of the baseboard 2 can be directly welded to the floor material 2, as shown in Figure c.
However, conventional jet heaters (hot air welding machines) are of a type that blows hot air forward from the tip, so if you try to weld with it, the hot air will be blown strongly against the wall, making it difficult to get a clean finish. Therefore, in the past, construction could only be done using the method described above.

Therefore, as a result of various experimental studies, the inventors of the present invention found that the fourth
We have developed equipment that enables waterproof flooring work as shown in Figure C, and we would like to offer it here.

[Means for solving problems]

This idea was made in order to solve the above problems.A guide shoe made of a slippery heat-resistant material such as Teflon or ceramic is provided on the lower surface of the tip of the main body, and the guide shoe is provided on the side of the tip of the main body. It is equipped with a spout that blows hot air diagonally downward to the bottom surface.

[Effect]

When the tip of the nozzle is inserted between the sheets to be bonded, the hot air is ejected to the side of the nozzle and diagonally downward, effectively heating only the area to be bonded. At the same time, other parts will not be damaged unnecessarily.

In addition, since the guide shoe 5 is made of a heat-resistant material with good sliding properties, it can be smoothly moved between sheets, and the nozzle can adhere to the sheets, especially the bottom sheet, and perform bonding work efficiently without damaging the sheets. I can do it.

〔Example〕

FIG. 1 shows an embodiment of this invention, in which 1 is a known jet heater, and 2 is an attachment type nozzle according to this invention which is fitted onto the tip of a hot air cylinder 3 of the jet heater 1 and tightened with a screw 4. It is the main body.

The nozzle body 2 has a spout 2a on the side of the tip,
Hot air H is ejected in a direction perpendicular to the axis of the nozzle body 2.

Further, a guide shoe 5 made of a heat-resistant material such as Teflon or ceramic that has good slippage and is difficult to adhere to flooring material is attached to the lower surface of the tip of the nozzle body 2. As shown in Figure 2, it is installed so that the hot air blows out diagonally downward.

Next, the usage will be explained as follows.

For the sake of explanation, we will use the waterproof adhesive work shown in Figure 4C as an example. After attaching the flooring material (R) to the floor surface (A) and the baseboard (2) to the wall surface (C), The tip of the nozzle body 2 is inserted under the floor contacting part X of the nozzle body 2, and the nozzle body 2 is moved in the direction of the arrow m while blowing out hot air H.

In this way, the upper surface of the floor material roll and the lower surface of the floor abutting part When the floor abutting part X is pressed with a pressure roller or a pressing roller, the floor abutting part X is neatly adhered to the floor material R.

The hot air H is blown onto the areas necessary for bonding, and the hot air is not blown directly in the direction of the wall C.
As with conventional jet heaters,
The wall side does not look unsightly like waves and has a beautiful finish.

In addition, the guide shoe allows the work to proceed smoothly, making it extremely useful as a waterproof gluing work tool.

Although the attachment type is shown here, it is of course possible to use a fixed type.

In addition, although the case of gluing baseboards has been explained here, it is also suitable for other uses, such as gluing tape, etc., and has excellent operability and good finish. It is an idea.
