Description

  The present invention is a brand-name brand that performs branding on the surface of various objects such as confectionery and bread, leather products such as bags and shoes, wooden products such as nameplates and confectionery boxes, and other burn marks. Relates to an effective heater.

  Speaking of the confectionery technology field as a representative example, a brand-name hand-operated brand-name stamped candy is used, and the heated seal on the tip of the candy is pressed against the surface of Japanese confectionery and its burnt marks. A certain mark made up of characters and figures.

  As a heat source for the seal at the tip, two types of gas burners and electric heaters (ceramic heater, nichrome heater, cartridge heater, etc.) are known. In this respect, Patent Document 1 discloses a gas burner, and Patent Document 2 discloses a cartridge heater. However, these both relate to an automatic mechanical printing apparatus, which relates to a so-called burning tool as a hand tool. It is not a thing.

  As a precaution, Patent Document 3 describes an electromagnetic induction heating device for a printed body, but this is not also intended for a branding as a hand tool, and further employs a lifting mechanism that moves in parallel links. Therefore, a clear branding cannot be reliably and stably applied unless the surface is a wooden board such as a menu tag or a nameplate with a flat surface.
