Description

Heat knife device on the tape-cutting machine

Technical field

The utility model relates to field of mechanical technique, is specifically related to the heat knife device on a kind of tape-cutting machine that is used for plastic optical fibre band cutting.

Background technology

In the conventional art, be used to cut the tape-cutting machine of plastic optical fibre band, its principle generally is by the current flow heats metal, by warmed-up metal heat is conducted to cutting knife again, and cutting knife is also heated, and cuts plastic tape by the cutting knife that generates heat.As Fig. 1 is the heat knife device of a tape-cutting machine commonly used, comprise major parts such as controller 1, tool rest 2, cutting knife 5, heating piece 6, heat insulation 7, cutting knife 5 is fixed on the centre of heating piece 6 and heat insulation 7, cutting knife 5, heating piece 6 and heat insulation 7 is done as a whole and fixed block 3 is fixed on the tool rest 2 together then, cutting knife 5 belows alignment edge bearing 4, edge bearing 4 plays backing plate; Heating piece 6 inside are equipped with heat-generating pipe 8 and temperature detector 9, and heat-generating pipe 8 is connected sense line 10 with temperature detector 9, and sense line 10 connects controller 1.The piece 6 that at first will generate heat under the effect of electric current heats, because heating piece 6 closely contacts with cutting knife 5, with cutting knife 5 heating, the cutting knife 5 of heat is used to cut plastic tape to heating piece 6 by hot conduction, and heat insulation 7 is used for heat insulation and insulation.Yet, there are several formidable shortcomings in this traditional heat knife device, first, owing to need to give earlier the heating piece 6 heating, give cutting knife 5 heating by the heat conduction again, its efficiency of heating surface is lower, utilization rate of electrical is low, all do not have effective way to solve, the speed of heating is also slow always, needs long heat time heating time; Second, because cutting knife 5 needs as far as possible closely to contact to improve the efficiency of heating surface with heating piece 6, and heating piece 6 generally all adopts square structure, so rectangular flat structure of cutting knife 5 general also employings and square cooperation, and thicker its shape of thickness is difficult to random variation as required, is difficult for cutting out shape miscellaneous; The 3rd, also need use parts such as heating piece 6, heat-generating pipe 8, temperature detector 9 in its structure, improved its cost, the structure of whole device is also more complicated; The 4th, under the normal power, temperature does not reach temperature required, and power is but burnt heat-generating pipe after increasing easily.

The utility model content

The technical problems to be solved in the utility model provides a kind of power saving, heats the heat knife device on the tape-cutting machine fast, that cutting knife can adopt multiple shape.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: the heat knife device on a kind of tape-cutting machine, comprise controller, tool rest, fixed block, edge bearing and cutting knife, cutting knife is fixed on the fixed block, fixed block is installed on the tool rest, it is characterized in that: described cutting knife directly passes through wire connection controller, electric current is directly given the heating of cutting knife mouth by lead, the cutting knife front and rear surfaces connects heat insulation, heat insulation is used for rising to cutting knife heat insulation, the effect of insulation, cutting knife is fixed on the side fixed block together with heat insulation, cutting knife, heat insulation and side fixed block as an overall fixed on tool rest, the tough alignment edge bearing of the cutter of cutting knife.

Further, described cutting knife two ends are provided with wire guide, and lead connects controller by wire guide, and electric current acts directly on the cutting knife mouth, do not have to conduct by the third party.

Further, described cutting knife thinner thickness, knife back portion is provided with some U type grooves, and U type groove is separated into the bar blocks that some tops separate, the bottom links to each other with the knife back of cutting knife.This structure both can reduce useless heating as much as possible, improved the speed of heating and the utilization rate of electric current, can save the material of making cutting knife again.

In addition, because electric current is directly given the heating of cutting knife mouth, cutting knife is thin, easy-formation, be not subjected to the restriction of his thing, therefore can make various shapes as required, as circular arc, waveform, zigzag or the like, the otch that cuts out to plastic tape also has various abundant shapes.

The utility model is by being directly connected to controller with cutting knife, electric current is directly heated to cutting knife, parts such as heating piece, heat-generating pipe, temperature detector had both been saved, reduced production cost, the efficient of more feasible heating and the utilization rate of electric energy are greatly enhanced, shortened heat time heating time greatly, therefore than more power saving of conventional art; The shape of cutting knife also no longer is restricted in addition, can make various shapes as required, thereby enriches the shape of otch.
