The switching driving rack A720 is further provided with a rack sliding groove A723, the rack sliding groove A723 is clamped with a rack guide rail A710 and can be assembled in a sliding mode, the rack guide rail A710 is fixed on the inner side of a feeding protection plate A170 close to the rack guide rail A710, one end of the switching driving rack A720 is assembled with one end of a rack pressure spring A520, the other end of the rack pressure spring A520 is fixed on a rack spring stress plate A171, the rack spring stress plate A171 is fixed on the inner side of the feeding protection plate A170 fixed with the rack guide rail A710, and the rack pressure spring A520 is used for switching and driving the rack A720 to generate elastic force for preventing the rack A from moving.
The top of the switching drive plate a410 is higher than the switching power block a225 at the initial state.
Fig. 4-10 illustrate the initial state of the feeder module with the ejector plate a310 positioned closest to the end of the feed motor. When the printing stock needs to be pushed to the feeding hole B111, the feeding motor is started, so that the pushing cover of the pushing rod A320 box is driven to move to push the printing stock entering the pushing channel A131 to the position above the feeding hole B111, the printing stock enters the feeding module B, the pushing rod moves to the maximum displacement at the moment, in the process, when the switching drive plate A410 penetrates through the switching power block A225, the switching drive plate A410 is positioned in the direction capable of rotating towards the pushing rod, so that the switching power block A225 extrudes the switching drive plate A410, and the switching drive plate A410 overcomes the elastic force of the switching pressure spring to rotate until the switching drive plate A410 penetrates through the switching power block A225.
Then the material pushing rod starts to move reversely, so as to drive the switching drive plate a410 to move towards the switching power block a225, at this time, because the switching drive plate a410 is higher than the bottom of the switching power block a225, the switching drive plate a410 can drive the switching power block a225 to overcome the elastic force of the switching spring to drive the second switching plate to gradually withdraw from the feeding channel a111, and the switching between the first switching plate a210 and the second switching plate a220 is realized. And after the first switch plate a210 and the second switch plate a220 are switched, the switch power block a225 can also move a certain distance to the feeding motor, at this time, the second material pushing latch a323 is engaged with the first switch power tooth a540 for transmission, so as to drive the first switch power tooth a540 to rotate circumferentially, the first switch power tooth a540 drives the second switch power tooth a550 to rotate circumferentially, the second switch power tooth a550 drives the switch driving rack a720 to move towards the material pushing cover a130 by overcoming the elastic force of the rack pressure spring a520, so that the first switch driving latch a721 drives the switch driving tooth a450 box to move towards the feeding motor, so as to drive the switch driving plate a410 to rotate towards the material pushing rod a320 by overcoming the elastic force of the switch pressure spring a440, at this time, the switch ball can effectively reduce the friction force between the switch driving plate a410 and the switch power block a225 until the switch driving plate a410 is lower than the switch power block a225, at this time, the switch driving plate a410 is not in contact with the switch power block a225, the switching drive plate A410 penetrates through the switching power block A225, and after penetrating through the switching power block A225, the switching drive plate A410 resets under the elastic force of the switching pressure spring A440, the second pushing latch A323 is separated from the first switching power tooth A540, and the first switching power tooth A540, the second switching power tooth A550 and the switching drive rack A720 reset under the elastic force of the rack pressure spring.
Preferably, the switching drive gear a450 is a one-way gear, and the locking direction is the direction for driving the switching drive plate a410 to rotate toward the lifter bar, and when the switching drive gear a450 is in the other direction, the switching drive gear a460 is not driven to rotate due to idle rotation. The pushing rod moves to the maximum displacement towards the feeding motor and then automatically switches the moving direction under the action of the reciprocating screw rod, then the second pushing latch A323 is meshed with the first switching power tooth A540 again to drive the switching driving rack A720 to move towards the feeding motor until being meshed with the switching driving tooth A450 for transmission, but the switching driving tooth A450 is idle and cannot drive the switching driving shaft A460 to rotate, so that the switching driving plate A410 is not influenced to pass through the switching power block A225.
In the embodiment, the feeding channel can be directly arranged right above the feeding hole B111, so that pushing is not needed, but the falling height of the printing stock is too large, and the printing stock is easy to jump, skew, damage and the like. The impact force on the printing stock can be reduced by rolling the printing stock to the feed inlet, so that the printing stock is protected.
