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.

Japanese Utility Model Publication No. 60-19496 JP 2009-298002 A Japanese Patent No. 3605151

  The publicly-known means of installing a stamper frame in a refractory brick heating furnace and heating the seal stamp placed on the insulator with a gas burner from below is an advantage that can be widely used for various types of branded stampers. On the other hand, since the heating temperature of the seal at the tip is not constant and is easily influenced by the outside air temperature and heating time, it is difficult to obtain a uniform mark such as the color tone and density of the burn mark, It cannot be heated.

  And even if a cassette cylinder type gas stove that eliminates the need for gas piping work is used, this can be said in the same way. Deterioration and risk of gas and fire accidents are also invited.

  Furthermore, since the stamp of the tip is exposed to a high temperature of about 600 ° C. to about 800 ° C., the oxidation progresses quickly, the service life is short, and impurities such as oxides and wrinkles generated in the seal are It may adhere to the surface of an object when performing branding, particularly if the object is a food, which may cause unsanitary and other adverse effects.

  On the other hand, the publicly known means for heating the seal at the tip with an electric heater such as a rod-shaped ceramic heater, cartridge heater, or sheathed heater has the advantage of preventing oxidation due to the above gas, but there is an upper limit on the heating temperature of the seal. In addition, since it cannot be heated to a high temperature, the number of stamps that can be processed per hour cannot be increased, resulting in poor work efficiency.

  In addition, it is necessary to manufacture the brand name in a dedicated form according to the electric heater, and various brand name brands already owned by confectioners cannot be heated as they are. If an attempt is made to heat the various types of branded shochu using an electric heater, a great deal of cost will be required.
