Abstract
The utility model relates to the ink ribbon conveying and recovering device of a printer, comprising a shaft body. One end of the shaft body is provided with an ink ribbon blanking adapter, a pressure spring, etc.; the other end of the shaft body is provided with a friction plate, a large felt pad, a fixed plate, etc.; the middle of the shaft body is provided with an ink ribbon shaft sleeve; the fixed plate is provided with a screw hole and is tightly fixed on the shaft body by a fastening screw; the end of the shaft body is provided with an antiskid component which can prevent reverse rotation. In this way, the ink ribbon component does not move in the work, and the working effect of the integration is improved; meanwhile, the design object that the shaft body is not reversely rotated is reached.
Description
Technical field
The utility model relates to a kind of office equipment, and especially the colour band of printer sends and retracting device.
Background technology
98221194 utility model patents disclose a kind of thermal transfer printer colour band R-T unit, this device is equipped with unilateral bearing between belt wheel and axle, utilize unidirectional transmission and the function that oppositely dallies, realization colour band and paper synchronization implementation are not printed and are sent and reclaim, and improve print quality with this.Referring to Fig. 1, when motor just changeed, the driven by motor unilateral bearing rotated with bigger power, and unilateral bearing drives axis body 13 again and rotates, because of fixed head 12 usefulness trip bolts 8 are fastened on the axis body 13, so fixed head 12 rotates together with axis body 13.The frictional force that fixed head 12 utilizes big felt pad 7 to produce drives friction plate 6 and rotates, and rotates thereby order about colour band axle sleeve 5, reaches the purpose that reclaims or provide carbon ribbon.When motor reverses, because the effect of unilateral bearing makes axis body 13 dally.Reclaim for regulating or provide the power of carbon ribbon, thereby the size of utilizing the size of regulating shaft end pressure to influence the frictional force that big felt pad 7 produces realizes.Regulate colour band plug 1; make compression spring 2 produce different pressure; pressure is delivered on the friction plate 6 by chip shield 3, little felt pad 4, colour band axle sleeve 5; thereby change the pressure between friction plate 6 and the big felt pad 7; the frictional force size of generation is changed; thereby change the power that the axis of ribbon wheel assembly reclaimed and provided carbon ribbon, accomplish the end in view.
But also inevitably there is following deficiency in the device of said structure:
1. about the location of fixed head 12, normally auger shell hole on axis body 13 is a unthreaded hole in the fixed head 12, and is fastening with trip bolt 8.This location structure, must control position and the gauge of fixed head 12 and the position of unthreaded hole of screw on the axis body 13 when making part processing, often machining accuracy can not reach designing requirement, make assembly to install in the method that adds screw distance on employing in the man-hour lengthening axis body 13 for this reason, must make the axis of ribbon wheel assembly axially produce the space like this, be moved in the course of the work, influence the complete machine effect.
2. about the counter-rotating of axis body, during owing to the unilateral bearing counter-rotating certain frictional force is arranged, this frictional force also can drive axis of ribbon wheel assembly backward rotation, and this is unallowed in the course of the work.
Summary of the invention
The utility model designs for overcoming above-mentioned defective, it is to realize like this, it comprises axis body, one end of axis body is provided with colour band plug, compression spring etc., the other end is provided with friction plate, big felt pad and fixed head etc., the centre is the colour band axle sleeve, and screw is set on the fixed head, by trip bolt fixed head is fastened on the axis body.
Prevent counter-rotational anti-skidding assembly in the setting of the end of axis body.Anti-skidding assembly comprises a pair of retardance abrasive disc, in the middle of the retardance abrasive disc compression spring is set, one end of retardance abrasive disc is the location split washer, and the other end is retardance felt pad and retardance brake pad, and the retardance brake pad will block brake pad by trip bolt and be fastened on the axis body; On the retardance brake pad screw is set; Compression spring is installed between the retardance abrasive disc by the abrasive disc reference column, and the damping axle sleeve is set on the abrasive disc reference column.
Adopt the utility model,, thereby guarantee this fixed head to be fixed on the axis body on any one position, can not be moved at work, improve whole work effect because tapping on fixed head utilizes trip bolt that fixed head is fastened on the axis body; On the other hand, owing to be provided with anti-skidding assembly, when motor just changes, the driven by motor unilateral bearing rotates with bigger power, unilateral bearing is driving the axis body rotation, and axis body overcomes the retardance brake pad and blocks the frictional force positive movement that the felt pad produces, and makes colour band assembly operate as normal.When motor reverses, because the effect of unilateral bearing, it is less that unilateral bearing offers the power of axis body, regulate the position of retardance brake pad on axis body this moment, change the length of compression spring, make the pressure change of compression spring, thereby change the retardance brake pad and block the frictional force that the felt pad produces, make this frictional force offset the frictional force that unilateral bearing produces, reach the purpose of design that axis body can not reverse.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1.
The specific embodiment
Referring to accompanying drawing; it comprises the axis body 13 that is arranged on the support column 11; one end of axis body 13 is provided with colour band plug 1, compression spring 2, chip shield 3 and little felt pad 4; the other end is provided with friction plate 6, big felt pad 7 and fixed head 12 etc.; the centre is colour band axle sleeve 5 and shell fragment 14; on the fixed head 12 screw is set, fixed head 12 is fastened on the axis body 13 by trip bolt 8.Because tapping on fixed head 12, utilize trip bolt 8 that fixed head 12 is fastened on the axis body 13, thereby guarantee this fixed head 12 to be fixed on the axis body 13 on any one position, can not be moved at work, improve whole work effect
Prevent counter-rotational anti-skidding assembly in the setting of the end of axis body 13.Anti-skidding assembly comprises a pair of retardance abrasive disc 16,21, the retardance abrasive disc connects by abrasive disc reference column 17, compression spring 2 is set in the middle of it, one end of retardance abrasive disc is location split washer 10, the other end is retardance felt pad 20 and retardance brake pad 19, on the retardance brake pad 19 screw is set, will blocks brake pad 19 by trip bolt 15 and be fastened on the axis body 13; Damping axle sleeve 18 is set on the abrasive disc reference column 17.
When motor just changeed, the driven by motor unilateral bearing rotated with bigger power, and unilateral bearing is driving axis body 13 rotations, and axis body 13 overcomes retardance brake pad 19 and the frictional force positive movement that retardance felt pad 20 produces, and makes colour band assembly operate as normal.When motor reverses, because the effect of unilateral bearing, it is less that unilateral bearing offers the power of axis body 13, regulate the position of retardance brake pad 19 on axis body 13 this moment, change the length of compression spring 2, make the pressure change of compression spring 2, thereby change retardance brake pad 19 and block the frictional force that felt pad 20 produces, make this frictional force offset the frictional force that unilateral bearing produces, reach the purpose of design that axis body 13 can not reverse.
