Abstract
A color band switching mechanism suitable for a wire printer is characterized by comprising a swing rod, a torsion spring, a support, a color band and a color band support; the shaft of the swing rod is provided with the torsion spring, and the swing rod and the torsion spring are arranged on the support; the color band is disposed on the color band support; a color band core is equally divided into two printing ink colors on the band; the color band support and the color band rotate around pins on the two ends of the color band support; the two ends of the swing rod are respectively provided with a swing arm; the swing arm on one end of the swing rod is linked with the color band support and the color band; when the swing arm on one end of the swing rod stays in an initial position under the effect of the torsion spring, one color is printed out by one color band with one printing ink color around the color band support; and the swing arm on the other end of the swing rod is stroke by a printing carriage so as to lift the color band support and the color band. In this way, the color band core moves upward onto the color band with the other printing ink color and to be pointed to a printing head, so that the other color is printed out. Through rotation and return of the swing rod, the color band is lifted and falls down, thereby realizing switching of colors of the color band.
Description
Technical field
The utility model relates to a kind of colour band switching mechanism that is applicable to impact printer.
Background technology
Because the variation of user's instructions for use, when needs are printed the word of two kinds of different colours, adopt the mode of Ribbon Change more pretty troublesome, simple to operate in order to pursue, a tractor serves several purposes promptly requires the attainable colour band switching mechanism of exploitation printer self.
Traditional colour band switching mechanism mainly is that a rail plate, gear drive and whole the moving of step motor control colour band are arranged, when needs are printed another kind of color, with colour band along the rail plate printhead that moved to another kind of ink colors regional alignment.The advantage of this mode is to realize the multi-color printing function, but total is complicated, and part is more, and cost is higher.
Summary of the invention
The purpose of the utility model provides a kind of colour band switching mechanism that is applicable to impact printer, through simple frame mode, overcomes the some shortcomings part of conventional printer, more perfectly realizes the needed double-colored printing function in market.Simple in structure, with low cost, installation, easy to maintenance.
The utility model is achieved in that
Be applicable to the colour band switching mechanism of impact printer; Comprise fork, torsion spring and support, colour band and colour band support; On the axle of fork a torsion spring is housed, fork and torsion spring are contained on the support, and colour band is contained on the colour band support; It is two kinds of ink colors that the colour band core is divided equally on bandwidth, and colour band support and colour band are around the pin rotation at colour band support two ends; One end swing arm interlock colour band support and colour band of fork, when an end swing arm of fork kept initial position under the effect of torsion spring, a kind of colour band of ink colors was printed a kind of color around the colour band support; The swing arm of word car bump fork one end makes the other end swing arm of fork lift colour band support and colour band, and the colour band core is moved upwards up to the colour band align printhead of another kind of ink colors thereupon, can carry out another kind of color and print.Rotation through fork and resetting makes colour band lift and falls, thus the color that realizes colour band switch, simple in structure, with low cost.
The restriction fork spacing square hole that automatically resets is arranged on the colour band support.When colour band support and fork disengaging, fork returns to initial position under the effect of torsion spring, and colour band support and colour band also return to initial position under the effect of gravity.Thereby realize the switching of colour band color.
The two ends swing arm of fork, two swing arms are mutually certain angle, and are middle continuous with axle, and two swing arms are monoblock types or split type with axle.
The beneficial effect of the utility model is: its structure is very simple, and is with low cost.According to the utility model structure, can realize the colour band handoff functionality, installation, easy to maintenance.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiments the utility model is done further detailed description.
Front view when Fig. 1 is the fork initial position.
Lateral plan when Fig. 2 is the fork initial position.
Lateral plan when Fig. 3 works for fork.
Fig. 4 is the 3D topology view of colour band switching mechanism.
The specific embodiment
Referring to Fig. 1,2,3,4, this switching mechanism mainly is made up of following parts: 1 fork, 2 torsion springs, 3 supports, 4 colour bands, 5 word cars, 6 colour band supports.
Fig. 1, Fig. 2 are the front and the lateral plan of fork initial position.Torsion spring is contained on the axle of fork, and fork and torsion spring are contained on the support, under the effect of torsion spring; The swing arm of fork one end leans against on the support, separates with the colour band support, and colour band support and colour band be limited to become level; This is an initial position, the color above the printable colour band core of colour band.
Lateral plan when Fig. 3, Fig. 4 work for fork and 3D topology view.Colour band is contained on the colour band support, can rotate together with the colour band support, and spacing square hole is arranged on the colour band support; There is a convexity word car side, when the word car moves, and an end of protruding bump fork; Till the swing arm that makes fork rotate to the other end was limited in the square hole, colour band and colour band support were lifted by swing arm together, and the colour band core moves to following color alignment printhead thereupon; Colour band can be printed another kind of color, thereby has realized the switching of colour band color.
This structure has been utilized existing part support and word car, has only increased by three part forks, torsion spring and colour band support, promptly can be to realize double-colored printing function.
As stated, the utility model has adopted simple structure, has realized the function that needs, and on double-colored printing function, has leading advantage, the diversified needs of printing that satisfy more.
Claims (3)
1. be applicable to the colour band switching mechanism of impact printer; It is characterized in that comprising fork, torsion spring and support, colour band and colour band support; On the axle of fork a torsion spring is housed, fork and torsion spring are contained on the support, and colour band is contained on the colour band support; It is two kinds of ink colors that the colour band core is divided equally on bandwidth, and colour band support and colour band are around the pin rotation at colour band support two ends; The two ends of fork respectively are provided with a swing arm, an end swing arm interlock colour band support and a colour band of fork, and when an end swing arm of fork kept initial position under the effect of torsion spring, a kind of colour band of ink colors was printed a kind of color around the colour band support; The one end swing arm of word car bump fork makes the other end swing arm of fork lift colour band support and colour band.
