Detailed description of the invention
See Fig. 1-2, the implementation case comprises splicing roller 10, the splicing coordinated with splicing roller 10 takes turns 11, locating paper sheets side mark 8, front lay 9, the tape with holes 6 of defeated paper, drive the reciprocating rotating wheel 5 of tape 6 with holes, drive the conjugate cam 1 of reciprocating rotating wheel 5, tape 6 with holes is positioned on defeated paper direction, front lay 9 has one by the air chamber 7 of negative-pressure adsorption paper, air chamber 7 is provided with the negative-pressure air valve with conjugate cam 1 synchronous opening/closing, reciprocating rotating wheel 5 drives the defeated paper of tape 6 with holes, negative-pressure air valve is opened just, after tape 6 with holes defeated paper to splicing roller 10, reciprocating rotating wheel 5 revolution, negative-pressure air valve is closed just, conjugate cam 1 is provided with conjugate cam frame 2, and conjugate cam frame 2 is conjugate cam enclosed frame, and reciprocating rotating wheel 5 is provided with fork 3, and fork 3 is connected with connecting rod 4, connecting rod 4 is connected by the connecting rod rest that waves with conjugation cam holder 2.For the ease of opening and ensure the accuracy of unlatching, the spool of negative-pressure air valve is coaxial with conjugate cam 1.
See Fig. 2, in concrete use, the transmitting ratio of conjugate cam 1 and the ratio i=1 of defeated paper, when reciprocating rotating orbit period 2 π (namely exporting paper backswing once) paper arrives front lay 9, negative pressure chamber is 0, reciprocal backswing wheel 5 remains static, through front lay 9, after fixed 8 of side mark, in front lay 9 bottom air chamber 7, negative pressure is opened and is held paper, send before beginning, when passing through splicing roller 10-12mm, print platform is sent to by splicing roller 10, certain safe and reliable distance must be passed through, after paper is controlled by print platform completely, splicing wheel 11 can be lifted, like this within 2 π times, complete a vacuum override type transfer, in paper handshaking, the linear velocity of tape 6 with holes is equal with the linear velocity of splicing roller 10.
Wherein, the splicing coordinated with splicing roller 10 11 speed of taking turns are V
splicing is taken turns, conjugate cam 1 does 2 π cycle constant speed revolutions, and constant angular velocity is ω, and conjugate cam 1 corner is
the angular velocity omega of fork 3
inamely through the cireular frequency identical (coaxial) of reciprocating rotating wheel
ω
imaxim is ω
max, the defeated linear velocity of tape with holes is V
max=R ω
max, R reciprocating rotating wheel radius, meets V
max=V
splicing is taken turns.Thus ensure that constant velocity hands over paper, improve transfer precision, thus ensure that vacuum surmounts paper feeding mechanism stability, accuracy and reliability.
