Description

[Detailed description of the invention] [Industrial application field] The present invention is a simple resin heat fusion method suitable for processing cut parts of exterior materials used when installing heat insulation and cold insulation materials for equipment, for example. Regarding machines.

[Prior Art] Equipment used for processing resin, such as rolling rolls, which sandwich a resin layer between two rolls and use heat and pressure to roll and deform the resin has been used as industrial machinery for a long time. There is.

However, no roll-like device has been found that is so-called "handy" and can be handled relatively easily and that can heat-fuse the resin layer.

BACKGROUND ART Equipment, piping, etc. installed indoors or outdoors are often covered with various materials to keep them warm, cool, or maintain their appearance, and the outermost layer is protected by a so-called exterior material.

The exterior materials used here are polyolefin-based, polyvinyl chloride-based resin plates, aluminum,
It is composed of metal plates such as steel and stainless steel.

Recently, exterior materials in which the surface of a metal plate is coated with a resin layer have been widely used due to its durability.

This product has a metal intermediate layer and a thermoplastic resin coating on both sides. For example, it is a laminate made of three layers such as polyvinyl chloride/aluminum/polyvinyl chloride, polyethylene/aluminum/polyethylene, etc. be.

When using such an exterior material to exteriorize the surface of a device, the exterior material is cut and processed according to the size of the target device. When the exterior material is cut, the cut surface will naturally expose the metal surface of the exterior material, for example, in the case of exterior materials that use metal, the surface should be sealed with a resin sealant to prevent corrosion of the exposed metal parts. This is common.

However, this sealing process requires a skilled technique, and depending on the sealant used, it is not always satisfactory in terms of deterioration and adhesion of the sealant itself. Corrosion may be a problem.

Therefore, there has been a need for a resin heat fusion machine that can be easily used during such construction.

[Problems to be Solved by the Invention] The inventors of the present invention completed the present invention as a result of their studies as described above, especially regarding a device for simply fusion-coating the cut portion of an exterior material.

[Means for Solving the Problems] That is, the present invention consists of two heating rolls that are parallel to each other in the axial direction and have a portion of their outer surfaces close to each other, and each of the rolls is independent of the other. The present invention relates to a simple resin heat fusion machine that is rotatable and has a handle that fixes the two rolls on one side in the axial direction.

Next, the present invention will be explained in detail based on the drawings.

FIG. 1 is an external view showing one embodiment of the present invention in use, and in the figure, 1 is two heating rolls, which are configured to be parallel in their axial directions.
The roll can be heated (can be heated up to at least 200° C.) with an embedded heater or the like, and its material is made of metal, rubber, or heat-resistant synthetic resin such as fluororesin. The gap between the rolls must be large enough to sandwich the resin laminate 3, which will be described later. These two rolls are fixed on one side in the axial direction by a handle 2.
The book rolls are a mechanism that can be rotated independently.

[Example] Embodiments of the present invention are shown below.

As mentioned above, the exterior material made of metal plates laminated with thermoplastic resin is made of, for example, polyvinyl chloride/aluminum/polyvinyl chloride laminates, and the thickness of these is usually 0.1 for the resin layer (one side).
~1 mm, and the thickness of the metal layer is 0.01-0.5 mm. The piping parts of equipment are coated with heat insulating material, etc., and a sheathing material is applied to the outer surface of the piping.In order to cover the exposed metal parts of the cut parts ((1) in Figure 2), the heating method of the present invention is used. As shown in Figure 1, the fuser is held between two rolls, and the melting temperature of the resin (140
Rotate the roll while heating to ~180℃) to coat (Figure 2, (2)).

In addition, a resin of the same quality as the thermoplastic resin constituting the laminate is made into a band shape, and the cut portion is covered with this resin (Figure 2 (3)) and heated with the roll of the present invention to a temperature higher than the melting point of the resin in the covered portion. Then, fuse this to the relevant part (cut part) (Figure 2 (4)).

[Effects of the invention] The present invention allows construction of resin coating etc. using a simple method.

[Brief explanation of the drawing]

Figure 1 is an external view of the present invention, in which 1 is a roll;
Reference numeral 2 indicates a handle for fixing the roll, 3 indicates an exterior material, 4 indicates a covering portion, and 5 indicates a coated finished portion. FIG. 2 shows a state in which the cut portion 1 of the exterior material is directly heated and covered, and FIG. 3 shows a state in which the cut portion 1 of the exterior material is covered with a band-shaped resin layer. FIG. 4 is a diagram illustrating a state in which a belt-shaped resin portion is heated and melted and coated. In FIG. 2, 6 indicates a metal portion, 7 indicates a band-shaped sheet for coating, and 8 indicates a resin layer.
