Technical Field

The invention relates to a printing device, in particular to a feeder comprising two groups of paper transfer suction nozzles.

Background

The invention content is as follows:

the technical problem to be solved is as follows:

the invention aims to overcome the defects that the paper conveying capacity of the existing paper transfer suction nozzle is poor and the speed of separating paper from two groups of paper nozzles is not matched. The invention aims to provide a feeder comprising two groups of paper transfer suction nozzle devices, which multiplies the paper conveying capacity of the paper transfer suction nozzles, fully adapts to the paper separation speed of two groups of paper nozzles and can accurately and stably transfer paper to a paper feeding roller. So as to further increase the working speed of the feeder for sheet-fed paper.

The technical scheme is as follows:

in order to solve the technical problems, the invention provides a feeder comprising two groups of paper transfer suction nozzles, which comprises a paper loosening blowing nozzle, an A-group paper nozzle, a B-group paper nozzle, an A-group paper transfer suction nozzle, a B-group paper transfer suction nozzle and a paper transfer suction nozzle moving and separating device.

The paper-releasing blowing nozzle, the A-component paper nozzle and the B-component paper nozzle are respectively provided with a blowing hole on the front side edge, the paper-releasing blowing nozzle is arranged on the left sides of the A-component paper nozzle and the B-component paper nozzle, the A-component paper nozzle and the B-component paper nozzle are arranged on the same plane, the A-component paper transfer suction nozzle and the B-component paper transfer suction nozzle are arranged on the right sides of the A-component paper nozzle and the B-component paper nozzle, the A-component paper nozzle and the B-component paper nozzle have the same action and 180-degree phase difference, and the A-component paper transfer suction nozzle and the B-component paper nozzle have the same action and 180-degree phase difference.

The moving and yielding device of the paper transfer suction nozzle comprises a spring 6, a swing rod 7, a yielding connecting rod 8, a sliding rail 9, a paper transfer suction nozzle sliding block 10, a sliding rail connecting rod 11, a connecting rod 12, a crank 13, a swing rod sliding block 14, a yielding cam 15 and a roller 16.

One end of the spring 6 is connected with the swing rod 7, the spring 6 enables the roller 16 on the swing rod 7 to be always in contact with the free cam 15, the swing rod 7 is connected with the free connecting rod 8 through the swing rod sliding block 14, two ends of the free connecting rod 8 are respectively connected with one end of the two sliding rails 9, the other ends of the two sliding rails 9 are respectively connected with two ends of the sliding rail connecting rod 11, two ends of the crank 13 are respectively connected with one end of the two connecting rods 12, the other end of one connecting rod 12 is connected with the paper transfer suction nozzle 31 of the group A, the other end of the other connecting rod 12 is connected with the paper transfer suction nozzle of the group B32, the paper transfer suction nozzle of the group A is fixedly connected with the sliding block 10, the paper transfer suction nozzle of the group B is fixedly connected with the other sliding block 10, the paper transfer suction nozzle of the group A is slidably connected with the sliding rails 9 through the sliding.

2 the working principle:

(1) the paper loosening blowing nozzle blows a plurality of pieces of paper on the paper stack to be loosened;

(2) the group A paper nozzles suck the first paper on the paper stack to move upwards to the top dead center position to be ready to be connected with the group A paper transfer nozzles; the component B paper nozzles fall down simultaneously and are inserted below the first paper to suck the second paper and blow air to completely separate the first paper from the paper stack;

(3) the group A paper delivery suction nozzles move forward to send out the paper (first paper) towards the direction of the paper feeding roller; simultaneously stopping blowing the component B paper nozzles;

(4) the group B paper nozzles (still sucking the second paper) move upwards to the top dead center to be ready to be connected with the group B paper transfer suction nozzles, and the group A paper nozzles fall down simultaneously and are inserted below the second paper to suck the third paper and blow air to completely separate the second paper from the paper stack;

(5) the group B paper delivery nozzles move forward to send out the paper (the second paper) to the direction of the paper feed roller; simultaneously stopping blowing the component A paper nozzles; so as to circulate

It is known that the two-component nozzle device of the prior art requires a time T for each separation of a sheet_{Is divided into}: comprises the time of the upward movement of a paper separating nozzle and the paper transferring time T of the paper separating nozzle and the paper transferring nozzle_{Crossing 1}The time of backward movement of the paper separating nozzle is the sum of the three (the time of the other half stroke is not counted because the time of the backward movement of the paper separating nozzle is exactly coincident with the falling time of the paper separating nozzle, the paper suction time and the air blowing time of the front air blowing opening of the paper separating nozzle, the same applies below)
