The utility model has advantages that the price is low, a very convenient and practical objective condition is provided for the regeneration of a broken laser printer, according to different fusing points of powdered ink and printing mediums of the printer, a heating temperature-controlled value of the thin film heater wire can be adjusted by changing the width of the position of a temperature sensor corresponding to the thin film heater wire, therefore, fuser temperature can be increased or reduced, and the range of application of the ceramic heating element can be extended.
Description
Technical field
The utility model relates to a kind of ceramic heating piece for laser printer.
Background technology
Ceramic heating piece for laser printer (Heating Element is hereinafter to be referred as H/E) is the heater members by the heating of high temperature sintering sheet resistance on the high-frequency ceramic substrate.His purposes in laser printer is with through adhering on paper ink powder after developing by after the high temperature melt, the firm permanent fixation method that adheres to a kind of advanced person on paper.His advantage is quick heating, power consumptive province, not only temperature precise control, reliable and stable but also serviceable life is very long.The H/E that the laser printer of external a lot of models uses makes of silicon nitride (or aluminium nitride), and the H/E cost of this material is very high.In addition, because the temperature sensor in the printer of different models all has different fixing positions, be placed on and nuzzle on the certain position of potsherd below the ceramic heating flake, and in the central processing unit in the printer of different model (CPU), when dispatching from the factory, just be provided with fixed (as 190 ℃) for the fixing temperature of printer.This causes very big difficulty with regard to giving the maintenance job of changing H/E, needs to be equipped with the H/E of a lot of models (different temperature control value).
Summary of the invention
The purpose of this utility model is to provide a kind of ceramic heating piece for laser printer, to solve very high, the inconsistent problem of temperature control value of cost that existing H/E exists.
The technical solution of the utility model is: sintered film heater wire on ceramic substrate, two ends at this film heater wire are provided with extraction electrode, be provided with dielectric passivation outside this conductive film, it is characterized in that: described ceramic substrate is an alundum (Al, and described overlayer is a glass glaze.
On described film heater wire, be provided with and be used to change widening line and subtracting narrow line of temperature.
The utility model has the advantages that:
1, price is very cheap, for the regeneration of the laser printer that damages provides very convenient and practical objective condition, helps environmental friendly regenerated development and popularization.
2, use is durable reliable, though the coefficient of heat conductivity of silicon nitride (or aluminium nitride) material and physical strength are all than alundum (Al height in theory, as long as on the circuit of heating resistor line, do suitable improvement and reinforcement, all be not less than the H/E that expensive silicon nitride material (or aluminium nitride) is made its serviceable life.Its price but has only 1/tens of silicon nitride, 1/10th of aluminium nitride.
3, ink powder fusing point that uses according to printer and print media is different, the heating temperature control value of the width adjustment film heater wire of the corresponding temperature sensing station by changing the film heater wire, can reach the effect that improves or reduce fixing temperature, expand the scope of application.
4, the film heater wire of Yin Zhiing (being the noble metal slurry with ruthenium generally) and the adhesion property of glass glaze slurry are fine, have saved the surface treatment process of the preceding necessary pickling of silicon nitride material (or aluminium nitride) substrate printing, have eliminated the operation of contaminated environment.
5, make easily, substrate material very easily obtains; Glaze is smooth, bright.
6, temperature rise is very fast, and the temperature precise control is stable.
Description of drawings
Fig. 1 is a split structural representation of the present utility model;
Fig. 2 is a planimetric map of the present utility model.
Embodiment
Referring to Fig. 1 and Fig. 2, a kind of ceramic heating piece for laser printer of the utility model, sintered film heater wire 5 on ceramic substrate 6, be provided with extraction electrode 2 at the two ends of this film heater wire 5, outside this film heater wire 5, be provided with dielectric passivation 1, it is characterized in that: described ceramic substrate 6 is 96% alundum (Al substrate, and described overlayer 1 is the glass glaze film.
On described film heater wire 5, be provided with and be used to change widening line 3 and subtracting narrow line 4 of temperature.
This widens line 3:
1, at first, when as film heater wire 5 thickness of heater evenly, when the width degree also equates, the resistance value of each section equates that also the thermal value during by same current equates that also the each several part temperature is uniform.When film heater wire 5 thickness evenly, when the width degree is unequal, the ground resistance per square of live width is little, the narrow ground resistance per square of line is big, because after voltage is added to same lead, electric current on the lead equates, the wide ground resistance per square of lines is little, and the power of unit length is just little, the narrow ground resistance per square of lines is big, the just big (power=electric current * voltage of the power of unit length; Owing to electric current equates that the resistance on the unit length does not wait, the pressure drop of generation does not wait yet on the lead, and the big voltage of resistance is just high), so the narrow just wide local height of local temperature of lines than lines.
2, because the temperature sensor in the printer of different models all has different relatively-stationary positions, promptly be placed on and nuzzle on the certain position of ceramic substrate 1 below the ceramic heating flake, and in the central processing unit in the printer of different model (CPU), fixing temperature for printer just has been provided with fixed when dispatching from the factory (as 190 ℃), when the film heater wire 5 that the utility model will be close to the position of temperature sensor is widened (widening line 3), the temperature of experiencing when sensor is 190 ℃, and other local temperature all are higher than 190 ℃.Otherwise, we when being close to the widening line 3 and narrow down of temperature sensor (subtracting narrow line 4), to be 190 ℃ be that all the other local temperature just are lower than 190 ℃ to the temperature of experiencing of sensor.
3, under the fixed situation of printer temperature and sensing station, the width of the film heater wire 5 by changing adjacent sensing station should become the height of the fixing temperature of integral printer.
Widen line 3 and subtract the width of narrow line 4 and temperature value that length can be controlled as required calculates or determines through overtesting.
Claims (2)
1, a kind of ceramic heating piece for laser printer, sintered film heater wire on ceramic substrate, two ends at this film heater wire are provided with extraction electrode, outside this film heater wire, be provided with dielectric passivation, it is characterized in that: described ceramic substrate is an alundum (Al, and described overlayer is a glass glaze.
