Description
Technical field
The utility model relates to the drive unit of print media in the digit inkjet printer, especially relates to a kind of print media drive unit that is used for the lightweight numerial code spray drawing.
Background technology
Existing digit inkjet printer is divided into two kinds of patterns, promptly heavy digit inkjet printer and lightweight digit inkjet printer.The former mostly adopts the large-scale precision rubber rollers to drive print media, and the latter then adopts pinch roller that print media is pressed on the friction driving roller, utilizes frictional force to make friction driving roller drive medium motion.The utility model relates to the latter.Fig. 1 is the structural representation of print media drive unit in the lightweight digit inkjet printer of prior art.Among the figure, blank web-like print media is by penetrating and place on the unwinding rack with its inner diameter of steel flue to the let off roll of coupling, during air brushing, pinch roller 1 compresses print media 2 to friction driving roller 3, during friction driving roller 3 rotations, drive print media 2 and forwards move, print media 2 is pulled out from unwinding rack 4.Be connected by rolling bearing 6 between unwinding rack 4 and the frame 5.The drive unit of this print media has following deficiency: 1, when single pinch roller hold down gag makes print media compacted, on friction driving roller, form the line contact, and frictional force and driving force are all less; 2, unwinding device itself does not possess power, when print media is drawn out, friction driving roller is still needed and is overcome the inertia of web-like print media, especially when the weight of print media is big, be difficult for usually being pulled, in the case, often need artificially print media to be put in advance, make its some medium hang on the rear of air brushing machine, operate very inconvenient, and when forgetting when print media put in advance, may have influence on the driven of print media, have a strong impact on the air brushing quality; 3, print media is installed on the unwinding rack by let off roll, must at first let off roll be penetrated in the medium inner core during operation, is placed on the unwinding rack again, comparatively bothers in the operation, and when medium is heavier, requires great effort very much.
Summary of the invention
The purpose of this utility model is in order to improve print media driving force deficiency in the above-mentioned prior art, easily to influence the air brushing quality, and print media installs the defective of inconvenience, effort, and a kind of new print media drive unit is provided.
The technical scheme in the invention for solving the above technical problem is: a kind of medium drive device that is used for light-duty digit inkjet printer, it is characterized in that adopting the double pressing roller type compactor, described compactor is made up of former and later two pinch rollers, forward and backward pinch roller connects by connecting plate, and is installed on the pressing plate by connecting pin.
Double pressing roller type compactor described in the utility model, its connecting pin make to form between connecting plate and the pressing plate and flexibly connect, and connecting pin roughly is positioned at the center of connecting plate.
Double pressing roller type compactor of the present utility model, make with flexible material on its forward and backward pinch roller surface.
A kind of medium drive device that is used for light-duty digit inkjet printer of the present utility model also can comprise a print media unwinding device and the auxiliary volume device that draws of print media.
Print media unwinding device described in the utility model is made up of two let off roll that are arranged in parallel, and it is connected in the frame bottom by rolling bearing, and is free to rotate separately; The spacing between two let off roll and the barrel dliameter of print media are complementary.
The auxiliary volume device that draws of print media described in the utility model, it comprises drive motors, driven roller and the pressure roller that matches with driven roller, the driven roller skin-friction coefficient is bigger, pressure roller is installed in the chute, pressure roller is pressed on the driven roller when sliding, drive motors drives the driven roller rotation, the web-like print media is pulled out from unwinding device, and carry to the air brushing district; Transporting velocity equal or when being slightly larger than air brushing print media in the pace in air brushing district.
In the print media unwinding device described in the utility model, two let off roll that are arranged in parallel are to prevent auxiliary rollover of drawing print media when rolling up device work, can two let off roll be arranged to have the drop of appropriateness according to drawing the volume direction.
Have the following advantages according to print media drive unit of the present utility model: media drive power is big; Print media drives reliable during air brushing; Print media is easy for installation, light.
