The purpose of the utility model can be realized by the following technical proposal:

the utility model provides a hot knife device, includes handle of a knife, heat insulating block and tool bit, and above-mentioned handle of a knife is shaft-like, and above-mentioned tool bit is platelike, and above-mentioned heat insulating block is located between handle of a knife and the tool bit and the both sides of heat insulating block link firmly with handle of a knife and tool bit respectively mutually, a serial communication port, the cutting part of tool bit front end for being used for cutting the work piece, the connecting portion that the tool bit rear end is connected for being used for with the heat insulating block, the tool bit middle part has the heating element who is used for heating the tool bit, has.

This cutters promotes tool bit temperature through heating element, because has the heat insulating block between tool bit and the handle of a knife, can avoid tool bit department high temperature conduction to handle of a knife department under the effect of heat insulating block.

In the heating process of the heating component to the cutter head, the cutting part after the temperature is raised can stably and smoothly cut the workpiece. Meanwhile, the energy loss caused by the transmission of overhigh temperature to the heat insulation block can be reduced under the action of the heat insulation structure.

In the above-described hot cutter device, the cutting portion has an inclined lead-in surface at an upper side thereof, a planar bottom surface at a lower side thereof, and a recessed escape portion at a lower portion thereof adjacent to the bottom surface.

The leading-in surface enables the smooth embedding of cutting portion by the cutting member in, and the setting of bottom surface can increase the stationarity in the cutting process. The avoiding part can be arranged to avoid the adhesion of the cut piece and the lower side of the cutter in the cutting process.

Of course, the cutting member close to the lead-in surface will slide out steadily along the lead-in surface.

In the above hot cutting device, the cutting head has positioning holes penetrating through both edges thereof, the electric heating rod is inserted in the positioning holes, the cutting part is a linear cutting edge, and the positioning holes and the cutting edge of the cutting part are arranged in parallel.

The electric heating rod can be stably positioned in the positioning hole.

In the above-described hot cutter device, end caps are connected to the cutter head at both sides of the cutting portion, and the above-described electric heating rod is positioned between the two end caps.

In the above hot cutter device, the end cap is connected to the cutter head by a fastener.

The end covers are connected to the two sides of the cutter head through fasteners, and the two end covers are respectively located at the two ends of the positioning hole, so that the electric heating rod located in the positioning hole can be stably positioned.

In the above hot cutter device, the heat insulation structure is a hollow through hole between the heating element and the connecting portion.

The structure not only can reduce the material consumption, but also can avoid the heat transition from being conducted to the heat insulation block.

In the above hot knife device, the heat insulation block is made of electrical wood.

Compared with the prior art, the hot cutter device has the advantages that the heat insulation structure is arranged on the cutter head, and the heat insulation block is arranged between the cutter head and the cutter handle, so that the temperature of the cutter handle is lower in the continuous heating use process of the hot cutter device, and the service life and the stability of the whole device are improved.

Meanwhile, the device adopts the electric heating rod for heating, and compared with ultrasonic heating, the device has the advantages of simple mechanism, lower cost and high practical value.
