First transmission gear, the change gear can be engaged with the first transmission gear, and the change gear is in the first elastic component and second
First transmission gear is kept away under the action of elastic component, first transmission gear is connect with transmission shaft driven.
As an improvement of the above technical solution, the left end of the transmission shaft is connected with the second transmission gear, and described second passes
Moving gear is engaged with the first transmission gear.
As a further improvement of the above technical scheme, first elastic component and the second elastic component are spring and cover
On the switching shaft.
It is further improved, the switching push plate is provided with the sliding sleeve being sleeved on the switching shaft, second elastic component
It is connected on the sliding sleeve.
It is further improved, the tooth of the change gear and the first transmission gear, which is provided with, is caught in chamfering, described to be caught in chamfering
The change gear is set and side that the first transmission gear is in contact.
The beneficial effects of the utility model are: change gear is in the first elastic component and the second elastic component under non-paper feed state
Under the action of be kept away from the first transmission gear, even if paper feed motor starts, power will not be transferred to paper feeding mechanism, printer
Not paper feed；When needing paper feed, word vehicle is moved to left side and paper feed switching sliding block is pushed to be moved to the left, and switching push plate follows paper feed to switch
Sliding block is moved to the left, and switching push plate is moved to left by the second resilient element urges change gear and engaged with the first transmission gear, paper feed
The power of motor is transferred to paper feeding mechanism by change gear, the first transmission gear and transmission shaft, carries out paper feed, is cut using word vehicle
Swap-in paper-like state ensure that printing and the linkage of paper feed, compact-sized, simple, advantageously reduce the manufacture and maintenance of printer
Cost.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model not paper feed state；
The structural schematic diagram of Fig. 2, Fig. 3 the utility model paper feed state.
Specific embodiment
Referring to Fig.1~Fig. 3, a kind of paper feed switching device of printer include that fixed bracket 1 and paper feed motor are driven
The change gear 2 of connection and transmission shaft 3 for connecting paper feeding mechanism 8, the fixed bracket 1 are provided with switching shaft 11, institute
Change gear 2 is stated to be slidably connected on the switching shaft 11 and can move freely along switching shaft 11, it is also sliding on the switching shaft 11
Dynamic to be connected with switching push plate 4, the switching push plate 4, which is provided with, switches sliding block 41, the change gear 2 by the paper feed that word vehicle pushes
Left side and fixed bracket 1 between be provided with the first elastic component 5, be arranged between the right side and switching push plate 4 of the change gear 2
There is the second elastic component 6；The first transmission gear 7 is also connected on the fixed bracket 1, the change gear 2 can be with the first transmission
Gear 7 engages, and the change gear 2 is kept away from first transmission under the action of the first elastic component 5 and the second elastic component 6
Gear 7, first transmission gear 7 are sequentially connected with transmission shaft 3.The left end of actually transmission shaft 3 is connected with the second driving cog
Wheel 31, second transmission gear 31 is engaged with the first transmission gear 7, and the right end of transmission shaft 3 passes through gear drive and upper paper machine
Structure 8 connects.Preferably, first elastic component 5 and the second elastic component 6 are spring and are sleeved on the switching shaft 11.
Preferably, the switching push plate 4 is provided with the sliding sleeve being sleeved on the switching shaft 11, and second elastic component 6 is connected to institute
It states on sliding sleeve.Using the above structure, when not upper paper-like state, i.e. ink-jet printer are in shutdown, print or lead ink-condition, at this time into
Paper switching device is in original state, the state as shown in Figure 1, change gear 2 in the first elastic component 5 and the second elastic component 6
Effect is lower to be in equilbrium position, and change gear 2 is not engaged with the first transmission gear 7 at this time, and therefore, paper feeding mechanism is not under this state
Work.Paper process in switching: pushing paper feed switching sliding block 41 toward moving left when word vehicle moves to left end, at this time there are two types of may, such as
Shown in Fig. 3, the first is that paper feed switching sliding block 41 is moved to the left by switching push plate 4, the second elastic component 6 promotion change gear 2,
When change gear 2 is just engaged with the first transmission gear 7, into upper paper-like state, paper feeding mechanism drives work by paper feed motor, real
Now upper paper function；As shown in Fig. 2, second is that change gear 2 collides with the first transmission gear 7, the second elastic component 6 at this time
Elastic force be greater than the first elastic component 5, when chart drive motor driving change gear 2 rotate when, in the effect of the elastic force of the second elastic component 6
Under change gear 2 can be made to engage with the first transmission gear 7, that is, enter upper paper-like state, to realize upper paper function.When upper paper is completed
Afterwards, word vehicle moves to right, and switching push plate 4 moves to right under the action of the second elastic component 6, and paper feed switching device restPoses.It utilizes
Word vehicle is switched into paper-like state, ensure that printing and the linkage of paper feed, compact-sized, simple, advantageously reduces the system of printer
It makes and maintenance cost.
In the present embodiment, it is preferred that the tooth of the change gear 2 and the first transmission gear 7, which is provided with, is caught in chamfering, institute
The side for being caught in that the change gear 2 is arranged in chamfering and the first transmission gear 7 is in contact is stated, above structure is convenient for change gear
2 and first transmission gear 7 be caught in engagement, reduce collision, improve service life.
The above, the only better embodiment of the utility model, but the utility model is not limited to above-mentioned reality
Example is applied, as long as its technical effect for reaching the utility model with any same or similar means, should all fall into the utility model
Within protection scope.
