Description

The two-sided head string of a kind of offset press device for ink

Technical field

The utility model relates to a kind of string device for ink of offset press, the two-sided head string of a kind of offset press of saying so more specifically device for ink.

Background technology

At present, the general black formula of string of floating that adopts of following wavers on the offset press, promptly descend wavers to rely on two springs up to withstand between first inking roller and second inking roller from the below, power source is from first inking roller, when machine runs to the regular hour, the elasticity of spring can weaken, pressure between first inking roller and the following wavers can reduce thereupon, following wavers is because of being short of power, phenomenons such as the difficulty that can rotate, pass China ink and the moving even China ink of string so just can't for effectively second inking roller, badly influence print quality.

The utility model content

The technical problems to be solved in the utility model provides a kind of two-sided string device for ink, can effectively solve down the dynamical problem of wavers, makes it keep enough and uniform China ink amount, guarantees the needs of production, has improved print quality.

For addressing the above problem, the technical scheme that the utility model adopted is:

The two-sided head string of a kind of offset press device for ink, comprise wavers down, the plate cylinder gear, described wavers down is installed on the wavers axle, it is characterized in that: an end of described wavers axle is equipped with down the black gear of string, escapement, carry out transmission by idler gear between described black gear of string down and the plate cylinder gear, the other end of described wavers axle is equipped with down the wavers gear, gear when one side of following wavers gear is engaged with control, when gear is installed in eccentric control during described control on the axle, be provided with rocking arm with the corresponding position of escapement on the described offset press frame, through-drive was connected when described rocking arm was controlled with off-centre with escapement respectively.

As further improvement in the technical proposal:

A side of axle was provided with chute when described rocking arm was controlled near off-centre, in this chute slide block was installed, and through-drive was connected when described slide block was controlled with off-centre.

Described rocking arm is equipped with bearing near a side of escapement, is provided with groove with the corresponding position of bearing on the described escapement, and described bearing is positioned at groove.

Adopt technique scheme, its powerdriven track is followed successively by plate cylinder gear, idler gear, goes here and there black gear, wavers, axle, slide block, rocking arm when gear, eccentric control when wavers gear, control down down down; rocking arm drives escapement and swings; driving down, wavers swings when rotating; make its inking amount even; the power source of following wavers is from gear drive; as long as machine turns; following wavers just can rotate; keep enough forever and China ink amount uniformly; supply the demand of production, improved print quality.

Come the technical solution of the utility model is further described below in conjunction with drawings and Examples:
