The printer is an output device that visually prints data processed by the information processing device on paper. Printers usually print information while transporting a print medium. In particular, in an electrophotographic printer, an electrostatic latent image is formed by scanning light on a photosensitive medium charged at a predetermined potential, and after developing with a toner of a certain color, an image is formed by transferring it to a printing medium. At this time, in order to fix the toner transferred to the printing medium on the printing medium, it is common that a fixing unit is provided in the printing path of the printer.

The fusing unit is generally located in a transport path of the print medium, and fuses the toner image transferred to the surface of the print medium by applying pressure and heat to the print medium to which the toner has been transferred. At this time, in order to pressurize and heat the printing medium, the toner is between a fixing roller which is generally controlled to have a surface temperature of a certain level or higher, and a pressing roller that rotates opposite the fixing roller to form a fixing nip in cooperation with the fixing roller. The transferred print medium is passed.

In order to heat the fixing roller, a heater, for example, a halogen heater, may be configured inside the fixing roller. Alternatively, a coil causing an electromagnetic induction phenomenon may be disposed on one side of the outer periphery of the fixing roller so that the fixing roller generates heat by an induction heating method. In addition, a heater may be configured in a hybrid form in which a coil is disposed on an outer circumferential side of the fixing roller while the heater is configured inside the fixing roller.

However, since the fixing belt or fixing tube constituting the fixing roller in such a fixing unit is continuously physically deformed while forming a pressing roller and a fixing nip, it is difficult to permanently use and easily damaged. Therefore, there is a need to increase the durability of the fixing roller.

In addition, the color and gloss of the toner image fused to the printing medium vary depending on the temperature of the fixing belt or the fixing tube, and a fixing unit capable of increasing the clarity of the toner color and enhancing the gloss is required.

Hereinafter, exemplary embodiments will be described in detail with reference to the accompanying drawings.

1 is a view showing the configuration of a fixing unit of a printer according to an embodiment, and FIG. 2 is a view showing the structure of a laminate of a fixing unit of a printer according to an embodiment.

3 is a view showing the configuration of a fixing unit of a printer according to another embodiment, and FIG. 4 is a view showing the structure of a stacked body of a fixing unit of a printer according to another embodiment.

Referring to FIG. 1, in a photo transfer printer, press and heat the print medium M to which the toner T has been transferred so that the toner T transferred to the print medium M is fused to the print medium M. The fixing unit 100 may be configured.

At this time, the fixing unit 100 may include a fixing roller 10 and a pressing roller 20.

The fixing roller 10 and the pressing roller 20 may be formed in a long cylindrical shape extending vertically to the conveying direction of the printing medium M, respectively, on the conveying path of the printing medium M as a whole.

In the state where the fixing roller 10 and the pressing roller 20 are engaged with each other, at least one of the fixing roller 10 and the pressing roller 20 rotates so that the printing medium M can move in the transport direction.

And the fixing roller 10 and the pressing roller 20 are in close contact with each other, and the toner T is formed on the printing paper M by forming a fixing nip while the fixing roller 10 is partially elastically deformed in the contacted portion. Can be compressed.

Looking at each configuration in more detail, the fixing roller 10 includes a laminate 11 in direct contact with the printing medium M and the toner T. The stacked body 11 may be formed in a hollow tube shape. At this time, in order to form the fixing nip in close contact with the pressure-sensitive roller 10, the laminate 11 may be provided with a fixing pad 13 inside the laminate 11. The fixing pad 13 applies a force in the outer radial direction from the inside of the laminate 11 so that the pressure roller 20 and the laminate 11 are in close contact.

However, in the embodiment shown in FIG. 1, the fixing pad 13 is not necessarily provided, and a core (not shown) made of a metal tube or the like contacting the inner peripheral surface of the laminate 11 is provided instead of the fixing pad 13 It may be.

However, when the fixing pad is provided without a core in the stacked body 11 as in the embodiment illustrated in FIG. 1, the heat generated by the heater 15 to be described later directly reaches the stacked body 11 to thereby stack the stacked body 11 ) Can shorten the time required for the outer peripheral surface to reach an appropriate fixing temperature.

On the other hand, the heater 15 transmits the radiated heat to the laminate 11 as a heating means for generating heat by an external power source, such as a halogen heater. Accordingly, the laminate 11 is heated to a predetermined temperature or more to apply heat to the printing medium M and the toner T to help fusion and drying of the toner T.

And the pressing roller 20 is provided with a pressing member 21 which is formed in a substantially cylindrical shape to form a fixing nip in engagement with the fixing roller 10 and is in close contact with the fixing roller 10 side.

The pressing member 21 rotates while the outer circumferential surfaces thereof are in close contact with the bottom surface of the printing medium M, thereby applying pressure to the printing medium M and the toner T passing through the fixing nip while moving the printing medium M. Can be applied.

The pressing member 21 may have elasticity, and a release agent may be coated on the surface so that the printing medium M is not attached to the pressing member 21.

The central shaft 23 of the pressing member 21 may be provided as a rotating shaft for rotating the pressing member 21, the elastic member 25 is coupled to the central shaft 23, thereby fixing the pressing member 21 to the fixing roller It may be configured to be provided with an elastic force toward (10).

In the embodiment in which the fixing unit is configured as described above, the laminate 11 of the fixing roller 10 may be configured as shown in FIG. 2. That is, the stacked body 11 may be formed in a tube shape in which different layers are sequentially stacked from inside to outside in the radial direction.

First, a base layer 11a may be formed on the innermost side of the laminate 11. The base layer 11a may be provided as a tubular film layer using a heat-resistant resin, and may be formed of, for example, a polyimide tube (PIT). Since the base layer 11a forms a base for forming the remaining layers constituting the laminate 11, it requires flexibility and durability, and is composed of a heat-resistant resin because it directly receives heat from the heater 15. It is appropriate. The base layer 11a is a tubular film layer composed of a heat-resistant resin, and may be formed to a thickness of approximately 0.01 to 0.015 mm.

Subsequently, a conductive layer 11b made of metal may be formed on the outer circumferential surface of the base layer 11a. The conductive layer 11b may be made of a metal having high thermal conductivity, and thus absorb heat emitted from the heater 15 and transfer it to the elastic layer 11d, which will be described later. The conductive layer 11b may be formed of, for example, a thin film layer of metal such as nickel. At this time, the nickel thin film layer may be formed to have a thickness of about 0.04 mm.

At this time, the conductive layer 11b may be formed in such a way that the base layer 11a is resin-plated to coat the metal coating layer. And the metal layer can be made by performing electroplating on the resin-plated metal film until the conductive layer 11b forms a certain thickness. As illustrated, nickel may be coated on a polyimide tube by a plating method to form a conductive layer 11b.

The conductive layer 11b is formed of a metal thin film layer having high thermal conductivity, and thus serves to quickly and evenly transfer heat generated from the heater 15 to the laminate 11.

And an elastic layer 11d may be formed on the conductive layer 11b. At this time, an adhesive may be applied between the conductive layer 11b and the elastic layer 11d so that the elastic layer 11d made of an elastic material such as silicone rubber can be attached to the conductive layer 11b of the metal. Accordingly, the adhesive layer 11c may be formed to a thickness of approximately 0.007 to 0.008 mm.

Meanwhile, the elastic layer 11d may be formed of a mixture of an elastic material such as silicone rubber and a heat-radiating filler having high thermal conductivity. At this time, the heat dissipation filler may be, for example, platinum, nickel, cobalt, graphite, or the like. They are not only high in heat resistance, corrosion resistance, and abrasion resistance in common, but also have excellent thermal conductivity. Therefore, in an environment of high heat and high pressure, damage to the elastic layer 11d is minimized, and heat of the conductive layer 11b is easily conducted to the release layer 11f, which will be described later, through the elastic layer 11d.

Here, when the silicone rubber is manufactured by a platinum catalyst curing method, a trace amount of a platinum component may be included in the silicone rubber, and the mixture forming the elastic layer 11d may include a heat dissipation filler of more than this trace amount of platinum. For example, an elastic material such as silicone rubber and a heat-radiating filler may be mixed in a weight ratio of 100 and 1.2, respectively.

Meanwhile, the elastic layer 11d may be formed to have a thickness of a predetermined level or more so that the laminate 11 can be elastically deformed to a level suitable for forming a sufficient fixing nip. The elastic layer 11d has a significant thickness compared to other layers, and for example, may be formed to a thickness of 0.25 to 0.3 mm.

An elastic material such as silicone rubber constituting the elastic layer 11d is not only high in thermal conductivity, but also has a considerable thickness of the elastic layer 11d as described above, so that the actual printing medium M and toner T It takes some time to reach an appropriate temperature state until the release layer 11f in close contact with. Therefore, the thermal conductivity and heat dissipation performance of the elastic layer 11d can be greatly improved by mixing the heat dissipation filler with the elastic material forming the elastic layer 11d. Accordingly, not only the time required to reach the release layer 11f at an appropriate fixing temperature is greatly shortened, but also the time wasted in sufficiently lowering the temperature of the overheated laminate 11 can be reduced.

Then, a release layer 11f is formed on the laminate 11. The release layer 11f is a layer that serves to prevent the toner T from sticking to the outer periphery of the laminate 11, and then forms an adhesive layer 11e by applying an adhesive to the above-described elastic layer 11d to form a release layer 11e. (11f) can be formed. At this time, the release layer 11f may be formed of, for example, a fluorine resin layer, and its thickness may be approximately 0.03 mm. Fluorine resins such as polytetrafluoroethylene (PTFE), polychlorotrifluoroethylene (PCTFE), and polyvinylideneporide (PVDF) have no adhesive or adhesive properties, thereby forming a release layer 11f. Can be used.

The laminate 11 having such a structure quickly and evenly absorbs heat generated from the heater 15, and then quickly absorbs heat absorbed by the heat dissipation filler of the elastic layer 11d to the release layer 11f. By smoothly conducting, the temperature control of the fixing unit is smoothed, and accordingly, the fixing performance of the toner is improved, resulting in an improvement in color clarity and gloss.

Furthermore, it has the effect of extending the life of the fixing roller by improving the durability, wear resistance and corrosion resistance of the highly deformed elastic layer 11d.

Meanwhile, according to another embodiment, as shown in FIGS. 3 and 4, the fixing unit 100 ′ has a fixing roller 10 ′ and a pressing roller 20 ′ as in the embodiment described based on FIGS. 1 and 2. Can be provided, and the overall configuration and functionality are generally similar.

However, in the fixing unit 100 'of the embodiment shown in FIGS. 3 and 4, the induction coil 15' disposed outside the stack 11 'instead of the heater 15 provided in the stack 11' This can be included.

The induction coil 15 'is a means for generating heat by eddy current itself in the laminate 11' using an electromagnetic induction phenomenon. In this case, the heating layer 11b 'is formed in the laminate 11'. Can be formed.

Specifically, when the current flowing through the induction coil 15 'formed on the outer side of the laminate 11' constituting the fixing roller 10 'changes, a magnetic field is generated, and the laminate disposed in the magnetic field ( 11 ') The nonmagnetic metal inside may generate heat by flowing an overcurrent.

To this end, the heating layer 11b 'may be formed of, for example, a non-magnetic metal including at least one metal selected from gold, silver, copper, aluminum, or alloys containing them.

Specifically, the laminate 11 'has a structure in which the base layer 11a', the heating layer 11b ', the elastic layer 11d', and the release layer 11f 'are sequentially stacked. Some adhesive layers 11c ', 11e') dl may be formed.

At this time, the elastic layer 11d 'may be formed of a mixture of an elastic material and a heat dissipation filler, and in this case, the heat dissipation filler may be made of at least one of platinum, nickel, cobalt, and graphite, or a mixture thereof.

In the embodiment in which the heating layer 11b 'is provided as described above, the conductive layer is not formed, but this is not necessarily the case. For example, when the fixing unit is a hybrid type including both a heater and an induction coil, a conductive layer and a heating layer may be provided together.

Therefore, in other embodiments, the heat generated in the heating layer 11b 'can be evenly transferred to the release layer 11f' evenly through the heat dissipation filler mixed in the elastic layer 11d '. The fixing performance for the film is improved, and a sharp and glossy image can be formed.

You will understand. Therefore, it should be understood that the above-described embodiments are illustrative in all respects and not restrictive.
