Abstract
The utility model discloses an improved generation laser copys printer heating plate, including the ceramic substrate, the ceramic substrate coats and is stamped the heating resistor silk, and the both ends of heating resistor silk are provided with the silver conductor of being connected with the printer power cord, and insulating glass layer has been laid on heating resistor silk surface, insulating glass layer and thermistor contact, thermistor is provided with thermal -insulated structure with the part of insulating glass layer contact the utility model discloses can improve the not enough of prior art, further improvement heating photographic fixing temperature.
Description
Technical field
The utility model relates to a kind of laser printing duplicating machine accessory, especially a kind of modified laser photography printer heating plate.
Background technology
Laser photography printer be by heating plate to attachment ink powder on paper after development by after high temperature melt, firmly permanent attachment is on paper to make image.Chinese utility model patent CN201417364Y discloses a kind of ceramic heating piece for laser printer, and cost is low, easy to use.But, in actual use, if the heating plate of genuine has changed other heating plate after damaging, then easily there is the problem that heating-up temperature reduces, caused it for the fixing poor effect of the label paper of heavy thickness.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of modified laser photography printer heating plate, can solve the deficiencies in the prior art, further improve heat fixer temperature.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows.
Modified laser photography printer heating plate, comprise ceramic substrate, ceramic substrate is coated with resistive heater, the two ends of resistive heater are provided with the silver conductor be connected with printer power supply line, resistive heater surface is equipped with insulating glass layer, insulating glass layer contacts with thermistor, and the part that described thermistor contacts with insulating glass layer is provided with heat insulation structural.
As preferably, described heat insulation structural comprises conductor sheet, and conductor sheet is arranged in insulating glass layer, and is covered in above resistive heater.
As preferably, the width of described conductor sheet is 1mm ~ 2mm.
As preferably, described heat insulation structural comprises the bend be arranged on resistive heater, and bend is arranged on the position being coated with thermistor, and bend makes resistive heater walk around from the both sides of thermistor.
The beneficial effect adopting technique scheme to bring is: the utility model can make the heating plate temperature of thermosensitive resistance measurement on the low side, because laser photography printer is all temperature automatically controlled, this just can make equipment improve the heating-up temperature of himself, thus the problem of the fixing deleterious avoiding machine to produce after changing non-original factory heating plate.
