Welding machine, packing body manufacturing device and packing body manufacturing method

Abstract

The invention provides a welding machine of a welding mold with simple structure capable of ensuring necessary welding strength, a packing body manufacturing device having the welding machine and a packing body manufacturing method. The welding machine comprises a welding mold and an anvil block. An object to be welded is welded with weld lines comprising a single weld line and non-parallel weld lines, wherein the single weld line is extended in single form linearly in a small thin film, and the non-parallel weld lines comprise two weld lines extended in which the distance is widened gradually far way from the single weld line. The oscillation surface of the welding mold comprises a single surface and a peripheral surface, wherein the single surface is formed into a shape corresponding tothe single weld line, the peripheral surface comprises a part corresponding to the non-parallel weld line in which the part is wider than the peripheral surface, and the oscillation surface is formedwith a groove between the single surface (2a) and the peripheral surface. The seat surface of the anvil block comprises a non-parallel surface and a central surface, wherein the non-parallel surface is formed into a shape corresponding to the non-parallel weld line, and the central surface comprises a part corresponding to the single weld line in which the part is wider than the central surface.

Description

technical field [0001] The present invention relates to a fusion splicer, a packaging body manufacturing device, and a packaging body manufacturing method, and in particular to a fusion splicer suitable for attaching an unsealing sheet capable of easily and cleanly unsealing the package on a package packaged in a sausage shape. A packaging body manufacturing device and a packaging body manufacturing method of the welding machine. Background technique [0002] Packages in which processed foods such as sausage and cheese are sealed are generally manufactured by filling a cylindrical film with contents and tying both ends. In order to facilitate the opening of the film of such a sausage-shaped package, it is known to weld a part of the opening sheet formed of a small film to the packaging film. When the packaging body is grasped and peeled off by the peeling sheet, the welded portion or its boundary or its vicinity serves as a starting point and the packaging film is destroyed...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned various welding technical solutions are only proposed from the viewpoint of preventing the opening sheet from curling in the direction away from the packaging film, so it is sometimes impossible to open the seal smoothly when actually trying to open the seal.

In addition, the anvil and soldering die of the above-mentioned structure in which protrusions corresponding to weld lines are formed on the anvil have the advantage of being able to simply form a structure of a soldering die that is expensive due to integral molding to oscillate ultrasonic waves, However, there are cases where the opening sheet cannot be welded with such strength as to damage the packaging film.
