The outside of electrothermal tube.
Preferably, radiating groove is parallel or vertical with the blade of blade.
Preferably, the outer surface of blade is additionally provided with heat emission hole, and multiple heat emission holes are set respectively along electrothermal tube direction.
Preferably, blade is equipped with a plurality of cooling duct, and a plurality of cooling duct is set around the electrothermal tube, and is cooled down
The both ends of passage are connected with pipeline, pipeline and circulating pump assembly connection, and cooling duct, pipeline and circulating pump form circulating cooling system
System, the interior cooling agent with flowing of circulating cooling system.
It is furthermore preferred that being additionally provided with temperature sensor and controller, temperature sensor is connected with controller, circulatory system control
Device control running.
It is operated it is further preferred that electrothermal tube is electrically connected with the controller and is controlled by controller.
Preferably, the one side of the blade is provided with position-limit foot.
The beneficial effects of the utility model：
Electrothermal tube is installed, electrothermal tube during work is to blade and knife in a kind of heat dissipation hot knife blade of the utility model
Sword provides heat, and temperature is become higher to materials such as cutting hides, braid over braid and adhesive tapes after blade is heated, and the utility model blade
Cleaved surface be equipped with radiating groove（Alternatively referred to as heat dissipation seam, thermovent）And/or heat emission hole, radiating groove are located at the outer of electrothermal tube
Side, due to electrothermal tube heating power, temperature rise, but temperature reaches a certain level, and electrothermal tube is easily burnt, the utility model
Radiating groove expands the heat dissipation area of blade, and radiating groove is located at the outside of electrothermal tube, i.e., the wall thickness on the outside of electrothermal tube compared with
It is thin, it is easier to disperse heat transfer, accelerating radiating rate prevents electrothermal tube high temperature from burning out to extend the service life of electrothermal tube.
