Therefore, the physical properties of the non-reinforced area 200a and the reinforced area 200b are different, so the amount of deformation generated when the reinforced area 200b is rotated by the driving wheel 101 is the same as that of the unreinforced area 200a when it is driven by the pressure roller 100. The amount of deformation produced is different between the two, so that the heating film 200 is easily wrinkled and twisted at the boundary line 200c due to the different deformation amounts on the left and right sides, and the life of the heating film 200 is shortened.
[0005] In addition, it is not easy to combine the heating film 200 with the reinforcing element 210. For example, if an adhesive is used for bonding, based on the above factors, the adhesive will gradually lose its adhesion and the film may fall off. , which will lead to slippage between the reinforcing element 210 and the heating film 200

Embodiment Construction
[0042] In order to overcome the shortcomings of the heat-conducting film in the prior art, the method used in the present invention is to locally increase the friction between the heat-conducting film and the pressure roller, so as to increase the driving force of the heat-conducting film without damaging the heat-conducting film. Effect.
[0043] see image 3 , is the perspective view of the appearance of the pigment fixing device of the printing equipment of the present invention; please also refer to Figure 4 , is the front view of the pigment fixing device of the printing equipment of the present invention. Among them, the pressurizing device 1 is divided into two contact parts 12 and a push part 10, the contact part 12 is located at both ends of the push part 10, that is, the outer part of the pressurization device 1, and the pressurization device 1 is obvious here It is a roller structure, so it can also be called a pressure roller 1, and is controlled by a motor M (o...

The invention relates to a pigment fixing device of a printing apparatus, which is provided with a pressurized device, comprising two touch parts and a pushing part. The pushing part is arranged between the two pushing parts and used for pushing a printing part, wherein, the pressurized device applies pressure to a heat conduction film and the two touch parts are used for driving the heat conduction film and the pressurized device to turn together.
Description
technical field [0001] The invention relates to printing equipment, in particular to a pigment fixing device for printing equipment. Background technique [0002] see figure 1 , is a side sectional view of the pigment fixing device of the existing printing equipment. Wherein the heating film 200 is set outside a heater seat 201, and in the heater seat 201 there is a heater 202, and a pressure roller 100 is driven by a motor M, and the heating film 200 and the heater are separated. 202 face to face, and exert a certain pressure on the heating film 200 . And a printing piece P is covered with pigment D, when the printing piece P carries the pigment D and passes through the pressure zone A between the pressure roller 100 and the heating film 200, the heat is conducted to the pigment D through the heating film 200 and squeezed out. Press into a flat shape like Pigment D'. Among them, the most important thing about the printing quality is that there must be no sliding between...
