Abstract
The utility model provides a colour ribbon receiving and dispatching device for heat rotary printer, which comprises a shaft 21, a pulley 14 arranged on a shaft end on one side of a vehicle 21 and a shaft body 9 sheathed on the shaft 21. The utility model is characterized in that a single-way bearing 13 is arranged between the pulley 14 and the shaft 21. The utility model can be used as the sending shaft and the receiving shaft of a heat rotary printer. The utility model has the advantage that paper discharging without printing and receiving between the ink ribbon and the paper can be achieved; the ink ribbon can not have crepe in the process of printing; besides, the ink ribbon can be saved.
Description
The utility model relates to office equipment, a kind ofly more precisely is used for colour band on the thermal transfer printer and sends and the device that reclaims.
The printing that utilizes thermal transfer printer embodiment such as train ticket etc. to have the value warrant of continuous programming code has been common technology.When relieving, behaviour is personnel and need knows current draft bank, and this just requires printer paper delivery and time paper under the situation of not printing.The rotating that known printer is printed rubber roll by control realizes the transmission and the recovery of ticket paper, yet can't realize that really not printing of colour band sends and reclaim.When not printing paper delivery, colour band is with the paper synchronized transmission, and when paper was return, colour band then can't reclaim synchronously with paper, caused colour band accumulation on paper thus, crumpled, and printhead can't clearly be printed.
The purpose of this utility model is: design a kind of colour band R-T unit that is used for thermal transfer printer and send axle and reclaim axle with the colour band that substitutes existing known technology, 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 simultaneously.
Thermal transfer printer colour band R-T unit provided by the utility model comprises axle, is positioned at the belt wheel and the axis body that is sleeved on the axle of axle one side shaft end, it is characterized in that: between belt wheel and axle unilateral bearing is installed.Linkage structure between axle and the axis body can be selected the known kind of drive for use, and the utility model is considered the stationarity of transmission of power, and its preferred structure is: connecting firmly a fixed cover near belt wheel one side on the axle, and corresponding with it, on axis body, connecting firmly fixed head; One friction pad is arranged between fixed head and the fixed cover; The other end at axle is being equipped with spring successively, and zygote and axle head backstop have a friction pad between zygote and axle head backstop.
Consider the factors such as reliability of transmission of power, aforesaid two friction pad refin felt pans.
The version of zygote is a lot, and one of embodiment of the present utility model is in the zygote axial end relative with spring one group of recessed edge to be arranged, and cooperates with recessed edge, is provided with straight pin in the end of axis body.
The quantity of flange can be selected two, and make its at interval angle be less than or equal to 120 degree and get final product.
Smooth in order to guarantee that colour band remains in the process that sends and reclaim, do not crumple, need make colour band bear certain tensile force.Be positioned at the outside of fixed cover in the utility model, suit wave washer successively on axle for this reason, hold-down ring, felt pad and locating ring.
For making colour band steadily stressed in the conversion that sends and reclaim, the utility model locating ring is provided with an alignment pin, and is corresponding with it, and one section deep-slotted chip breaker is arranged on gripper shoe.
In the use, respectively as the transmission axle of thermal transfer printer with reclaim axle, make opposite the getting final product of unilateral bearing transmission direction on sending axle and reclaiming spool with the utility model.When colour band reclaims axle be initiatively the time, and colour band advances, this moment colour band to send axle be driven shaft, spur by colour band and rotate; Opposite when the colour band rollback, it is initiatively that colour band sends axle, and it is driven that colour band reclaims axle.
The utility model has the advantages that: realized that colour band and paper synchronization implementation do not print paper delivery and recovery, and colour band is smooth in print procedure, wrinkle resistant, printing effect is clear, saves colour band.
Introduce embodiment of the present utility model below in conjunction with Figure of description:
Figure of description 1 is a structural representation of the present utility model;
In the accompanying drawings 1---axle head backstop, 2---trip bolt, 3---friction pad, 4---zygote, 5---straight pin, 6---axle sleeve, 7---spring, 8---spring leaf, 9---axis body, 10---fixed head, 11---fixed cover, 12---bearing, 13---unilateral bearing, 14---belt wheel, 15----gripper shoe, 16---locating ring, 17---the felt pad, 18---hold-down ring, 19---wave washer, 20---friction pad, 21---axis body, 22---flange, 23---alignment pin.
As shown in the figure: axle 21 of the present utility model is fitted on the gripper shoe 15 of thermal transfer printer through bearing 12 effects.In the outside of bearing 12, on the axle 21 unilateral bearing 13 is installed, belt wheel 14 is fitted on the unilateral bearing 13.
Axis body 9 is sleeved on the axle 21.Be the resistance of reducing friction, between axis body 9 and axle 21, two axle sleeves 6 be installed.In the left side of axis body 9, outside by axis body 9, suit successively on axle 21: the fixed head 10 that connects firmly with axis body 9, the friction pad of being made by felt 20 is with the fixed cover 11 that axle 21 connects firmly, wave washer 19, hold-down ring 18, felt pad 17 and locating ring 16.One (or whole process) alignment pin 23 that connects firmly is thereon arranged on the locating ring 16, corresponding with alignment pin 23, one section deep-slotted chip breaker is arranged on gripper shoe 15.Be sleeved on axle on the right side of axis body 9 and be followed successively by spring 7 on 21, zygote 4, felt system friction pad 3 and with the axle head backstop 1 of internal thread rotation set on axle 21.There are 22, two flanges of two flanges 22,120 degree at interval at the left end face place of zygote 4.Between two flanges 22, have and hold the straight pin 5 that connects firmly on axis body 9 one by one.
Adjust axle head stop 1, the pressure that spring 7 is acted on the zygote 4 extremely sets value, and screws trip bolt 2 then with axle head backstop 1 location.At this moment, under the effect of spring force, zygote 4, friction pad 20 is pressed against with axle head backstop 1; The fixed head 10 of opposite side, friction pad 20, fixed cover 11 also is pressed against together.Power by belt wheel 4 through unilateral bearing 13 be delivered to the axle 21 on, subsequently respectively by fixed cover 11 through friction pad 20, fixed head 10 is delivered to axis body 9; Pass to zygote 4 by axle head backstop 1 through friction pad 3, cooperate with straight pin 5 by the flange on the zygote 4 22 again to be passed to axis body 9.Because friction pad made by felt, and be provided with transition gap between zygote 4 and the straight pin 5, make when axis body 9 drives colour bands like this or colour band has good buffering effect when spurring axis body 9, guaranteed the stationarity of ribbon motion.
Hold-down ring 18, felt pad 17 and locating ring 16 1 pressure are given in the wave washer 19 distortion backs that are positioned at the left side of fixed cover 11.Because locating ring 16 cooperates the location through alignment pin 23 with deep-slotted chip breaker on the gripper shoe 15, therefore, this pressure makes felt pad 17 and 16 generations of locating ring frictional force.By this frictional force effect, make colour band tensioning all the time in motion process.
