The utility model content
Main purpose of the present utility model is to provide a kind of printer and paper winder thereof, and the paper winder complete function can facilitate the use operation of printer greatly.
To achieve these goals, the utility model proposes a kind of paper winder of printer, comprise motor, by the power train of this driven by motor and the paper tray that driven by this power train, but this motor is the motor of controlled forward or reverse, and this paper winder also comprises controlling the button of this motor forward/counter-rotating; This power train comprises the grating gear that is connected with this paper tray, and this paper winder comprises also whether the U-shaped photoelectric sensor that matches with this grating gear the paperboard state occurs to detect.
This power train also comprises the travelling gear that matches with this grating gear, the slipping device that matches with this travelling gear, the Timing Belt that coordinates with this slipping device and the reduction gearing that matches with this Timing Belt, and this reduction gearing is installed on the axle of this motor.
This slipping device comprises unidirectional torsion spring.
This grating gear comprises code-disc, and this U-shaped photoelectric sensor matches with this code-disc.
This button is third gear switch, three positions of this third gear switch respectively corresponding motor forward, stop and reversing.
To achieve these goals, the utility model also proposes a kind of printer, comprises above-mentioned paper winder.
Compared with prior art, printer of the present utility model and paper winder thereof, by button, grating gear and the U-shaped photoelectric sensor of controlling motor forward/counter-rotating is set, can realize the forward of paper roll/counter-rotating, and carry out the paperboard state-detection, complete function can facilitate the use operation of printer greatly.
Description of drawings
Fig. 1 is the front view of the paper winder embodiment of printer of the present utility model.
Fig. 2 is the enlarged drawing of D local in Fig. 1.
Wherein, description of reference numerals is as follows: 1 frame; 2 motors; 3 reduction gearing; 4 Timing Belts; 5 grating gear 51 code-discs; 6 paper trays; 7 U-shaped photoelectric sensors; The 8 unidirectional torsion springs of slipping device 81; 9 travelling gears.
The specific embodiment
In order to describe structure of the present utility model and characteristics places in detail, hereby lift following preferred embodiment and also coordinate description of drawings as follows.
Referring to Fig. 1 and Fig. 2, printer of the present utility model and paper winder embodiment thereof comprise: frame 1, motor 2, reduction gearing 3, Timing Belt 4, grating gear 5, paper tray 6, U-shaped photoelectric sensor 7, slipping device 8 and travelling gear 9.
The common power train that is connected between this motor 2 and paper tray 5 that forms of this reduction gearing 3, Timing Belt 4, grating gear 5, slipping device 8 and travelling gear 9.This motor 3 can drive this paper tray 5 by this power train and rotate.
This motor 2 is installed on this frame 1, but it is the motor of controlled forward/counter-rotating.This paper winder also comprises controlling the button (scheming not shown) of this motor forward/counter-rotating, and in the present embodiment, this button can be third gear switch, three positions of this third gear switch respectively corresponding motor forward, stop and reversing.
This reduction gearing 3 is installed on the axle of this motor 2.
This Timing Belt 4 matches with this reduction gearing 3.
This slipping device 8 is installed on this frame 1, matches with this Timing Belt 4.Which is provided with the power of pullling that unidirectional torsion spring 81 can provide to regulate Timing Belt 4.
This travelling gear 9 matches with this slipping device 8.
This grating gear 5 is installed on this paper tray 6, and it matches with this travelling gear 9.This grating gear 5 is provided with code-disc 51.
This U-shaped photoelectric sensor 7 is installed on this paper tray 6, and it matches to detect the rotation of this paper tray with the code-disc 51 of this grating gear 5.
The operation principle of printer of the present utility model and paper winder thereof roughly comprises: provide power by this motor 2, can drive these paper tray 5 rotations and reach automatic coil paper effect via this power train; When paper rolls tightly, can prevent effectively that by this slipping device 8 paper from pullling printhead; Can effectively detect printer by coordinating of the code-disc 51 of U-shaped photoelectric sensor 7 and grating gear 5 and whether be in the paperboard state, particularly: when printer is printed certain-length, power train drives paper tray 5 and rotates, the code-disc 51 of this grating gear 5 rotates simultaneously, and U-shaped photoelectric sensor 7 can detect voltage change; When coil paper was complete, code-disc 51 stopped operating, and coil paper is completed; When paperboard occured, paper tray 5 can not be rolled onto paper, and the code-disc 51 of this grating gear 5 just can not rotate, and the detection voltage that U-shaped photoelectric sensor 7 provides does not change, and after continuous three times, printer reports an error and quits work, and can avoid printer continuous operation damage printer; In addition, under the good situation of paper tray 5 fixed installation, can by action button make motor 2 drive paper trays 5 just/opposite spin.
Compared with prior art, printer of the present utility model and paper winder thereof, by button, grating gear 8 and the U-shaped photoelectric sensor 7 of controlling motor 2 forward/counter-rotatings is set, can realize the forward of paper roll/counter-rotating, and carry out the paperboard state-detection, complete function can facilitate the use operation of journal printer greatly.
Above, be only the preferred embodiment of the utility model, be intended to further illustrate the utility model, but not it is limited.All simple replacements of carrying out according to above-mentioned word and the disclosed content of accompanying drawing are all at the row of the rights protection scope of this patent.
