Abstract
The utility model relates to a contact-type duplicator fixation device with downward heating and negative pressure, which is characterized in that the device mainly comprises a negative pressure room (1), a permeable plate (8), and a heating plate (3), the negative pressure room is provided with two permeable plates, the horizontal setting of which is on the same level with the in and out printing papers, and the horizontal setting has a plurality of air holes (2), and the heating plate (3) of the same width with the printing papers is provided between the two permeable plates, and the pumping fan (9) is provided inside the negative pressure room. The utility model is applicable to the fixation components of the duplicator, and this utility model has simpler structure and better duplicating effects, in particular that the jam and wrinkle phenomenon of the printing papers can hardly happen on this device.
Description
Technical field
The utility model belongs to a kind of parts of duplicating machine, and concrete is a kind of fixing device of duplicating machine.
Background technology
Duplicating machine is a kind of use office equipment very widely.Its fixing device is one of them very important parts.The fixing member of duplicating machine commonly used has warm-up mill cartridge type, heating screen type, photographic fixing press belt type or the like now, and they respectively have certain practicality and advantage, but all come with some shortcomings, and as the easy wrinkle of copy paper, power consumption is big etc.Therefore, need to propose more advantages of simple of a kind of structure, be difficult for paper folding, the duplicating machine fixing device of photographic fixing better effects if.
The utility model content
The purpose of this utility model is at the problems referred to above, proposes a kind of negative pressure of heating down contact duplicating machine fuser, and it adopts negative pressure chamber, and the structure of air permeable plate and heating plate makes copy paper be difficult for wrinkle, the photographic fixing better effects if, and simple in structure.
The purpose of this utility model is achieved through the following technical solutions: a kind of negative pressure of heating down contact duplicating machine fuser, it is characterized in that: mainly form by negative pressure chamber, air permeable plate, heating plate, be provided with two air permeable plates above the described negative pressure chamber, this air permeable plate horizontal setting, with the turnover copy paper on a surface level, be provided with a plurality of pores above, be provided with between described two air permeable plates one with copy paper with wide heating plate, in described negative pressure chamber, be provided with extraction fan; Described heating plate is presented the convex face.
The utility model is owing to adopted the structure of negative pressure chamber and air permeable plate, in copy paper duplicating process, can be under the effect of negative pressure after coming out from light-sensitive roller, entirely, not pressurized wheels extruding, and very closely the state of contact hot plate is down through this fuser, and the heating plate that is provided with in the middle of air permeable plate is outstanding slightly arcwall face, makes the effect of duplicating photographic fixing improve greatly.Therefore, the utility model compared with prior art has simple in structurely, and copy paper is not easy wrinkle, the advantage of photographic fixing better effects if.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is described further: embodiment: with reference to accompanying drawing, a kind of duplicating machine fixing device, mainly form by negative pressure chamber 1, air permeable plate 8, heating plate 3, be provided with two air permeable plates above the described negative pressure chamber, this air permeable plate horizontal setting, with the turnover copy paper 4 on a surface level, be provided with a plurality of pores 2 above, be provided with between described two air permeable plates one with copy paper with wide heating plate 3, the curved convex surface of this heating plate is provided with extraction fan 9 in described negative pressure chamber.
The utility model is installed in photosensitive drums 5 and transfer roll 6 back, paper output wheel 7 fronts.Can be according to the size design of supporting duplicating machine different specifications.
Claims (2)
