Embodiment 1

[0037] Figure 1 to Figure 3 As shown, a fixing device provided in this embodiment includes: a heat insulating device 1, which is covered on the heat roller 2 and the pressure roller 3, and forms a heat insulating space inside to keep the heat generated by the heat roller 2, Both ends of the heat insulation device 1 along the length direction are provided with sealing parts, and the sealing parts are used to block heat loss from the two ends of the heat insulation device 1 . The inside of the heat roller 2 in this embodiment is a hollow structure, and a heat source, such as a halogen lamp, is installed in the hollow structure. The heat generated by the heat source penetrates the surface of the heat roller 2 and radiates into the printing space of the fixing device to realize the heating and fixing function. During the medium printing process of some fixing devices, in order to ensure that the printing environment temperature can reach the preset value, the heating temperature ...

Embodiment 2

[0048] This embodiment provides an image forming device including the fixing device described in Embodiment 1, which has the characteristics of low energy consumption, and because the heat energy discharged from the fixing device is reduced, thereby reducing the influence of heat on the structure that cooperates with the fixing device The degree can effectively increase the service life of this part of the structure, and in the design and selection, the structure of the joint can use materials with lower heat resistance requirements, thereby reducing the cost of the entire image forming device.

Abstract

The invention provides a photographic fixing device and an image forming device. The photographic fixing device includes a heat insulating device which is disposed on a heat roller and a pressure roller and internally has the heat insulating space therein to maintain heat generated by the heat roller, wherein the heat insulating device is provided with blocking portions at both ends in the lengthdirection, and the blocking portions are used for blocking the heat from being lost from both ends of the heat insulating device. The photographic fixing device is advantaged in that the heat insulating device can maintain the excess heat released by the heat roller in the printing process in the space formed through the heat insulating device, the retained heat remains in the insulated space of the heat insulating device and can be used for maintaining the temperature of the printing environment, so the heat supply of the heat roller to the printing environment is reduced, and thereby photographic fixing energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of image forming, in particular to a fixing device and an image forming device. Background technique [0002] The fuser unit is a key part of the laser printer, through the generation of high temperature, the toner is melted and finally fixed on the paper. [0003] The fixing unit in the prior art is provided with a heat roller and a pressure roller, and a halogen lamp is arranged in the heat roller, and the halogen lamp is turned on to heat the heat roller. Heat and pressurize to fix the toner etc. on the printing medium. [0004] However, there are two disadvantages of heating toner at high temperature: one is that the generated high temperature is dissipated to the inside of the machine, causing the internal temperature of the machine to rise, and the heat resistance level of the parts needs to be improved. Even if a fan is used for heat dissipation, it is easy to cause damage during continuous printing ...
