Description

Paper device on offset press

Technical field

A kind of offset press is the utility model is related to, paper device on more particularly to a kind of offset press.

Background technology

Offset press is that a kind of adhered to indirect printing principle, ink and water by ink rubber roll balance system is rolled in print The cylindrical printing plate face of plate cylinder, engaged by blanket cylinder with plate cylinder and clip the rolling of stationery stock, by required printing plate Picture and text are transferred to the machine printed on the stocks such as business card, drop, postcard, various cards.Paper card as stock Piece is stacked on layboy, and paper is put on paper feeding platform by paper advance mechanism and is transported to area to be printed, is involved in and is printed by roller.

Paper device refers to the Chinese patent of Application No. 201420721682.0 on existing offset press, and it discloses one Paper advance mechanism of the kind for offset press, including fuselage, layboy, paper feeding platform, in addition to for adsorbing the suction of paper on layboy Adsorption device, hydraulic cylinder, positioning photoelectric sensor and servo for detecting paper position for controlling adsorbent equipment to lift Motor, including the adsorbent equipment of sucker are fixedly connected with hydraulic cylinder, position photoelectric sensor and servomotor coupling, servomotor Conveyer is connected with, conveyer is fixedly connected with hydraulic cylinder.The paper of ranked and stacked pile is placed on layboy, servo electricity Machine transports the top of paper according to signal driving hydraulic cylinder, and adsorbent equipment is delivered to paper by hydraulic cylinder by the elongation of itself Surface, then vavuum pump pumping, sucker form negative pressure, first paper adsorption of contact are got up, and then servomotor is transported Make so that sliding component slides in slide rail, is slid onto target location and is adsorbed with the adsorbent equipment of paper and is being in paper feeding platform just During top, then sucker does not re-form negative pressure, and paper is just transported on paper feeding platform, and paper feeding platform is transported it into inside offset press Offset printing is carried out, then servomotor is again started up, and hydraulic cylinder and adsorbent equipment are conveyed once again to the surface of layboy, followed Ring is reciprocal.

But because the speed of general batch printing is per hour up to ten thousand, when sucker quickly inhales the paper of topmost one It is attached, lift and caused low pressure, may cause under the paper that has been adsorbed due to the electrostatic between paper and by paper Face one, which is opened, to be driven, and is produced and is floated, offsets pile or even slid from pile.

Utility model content

When the purpose of this utility model is to provide one kind and prevents that the top paper is adsorbed, below the offset printing that is driven of paper Paper device on machine.

Above-mentioned technical purpose of the present utility model technical scheme is that：

Paper device on a kind of offset press, including fuselage, layboy, paper feeding platform, adsorbent equipment, for controlling adsorbent equipment liter The servomotor that hydraulic cylinder, slide rail and the driving hydraulic cylinder of drop slide on slide rail, layboy and paper feeding platform are fixed in machine With, above layboy and paper feeding platform, at least two limited posts, spacing intercolumniation are connected with layboy respectively for slide rail both ends The heap paper space placed formed with paper supply heap, limited post are arranged with some pressure rings for pushing down paper edge outside.

By using such scheme, between pile is placed on into limited post, and the pressure ring outside limited post is set in by pile Edge push down, adsorbent equipment absorption paper after, adsorbent equipment by cylinder drive rise while, by the bullet of paper itself Property, paper edge is adsorbed pulling out under device pressure ring, and next paper continues to be pushed down by pressure ring, ensures the paper being adsorbed One is not driven below, that is, ensure that the neat of pile, and then ensure that being smoothed out for paper feeding；Meanwhile limited post also rises Spacing effect has been arrived, the surrounding of pile is clamped, prevents pile from tilting.

Preferably, one pressure ring of setting and pressure ring and limited post slide connection on each limited post, the lower surface of pressure ring is begun The edge with pile upper surface abuts eventually.

By using such scheme, whenever paper is adsorbed after device siphons away, pressure ring is influenceed by self gravitation and along spacing Post slides downwards, continues to push down the edge of next paper, ensures the smooth of pile；And pressure is directly arranged on limited post Ring, it is easy to set, beneficial to implementation.

Preferably, layboy cross section is rectangular, limited post has four and is located at the surrounding of layboy respectively.

By using such scheme, pile is placed on layboy, makes one of four limited post difference positions and pile Side abuts against, and ensures that paper is pushed down four edges by four pressure rings, and so as to which paper abuts stabilization, any side is all without caused floating Phenomena such as dynamic.

Preferably, limited post is threadedly coupled with layboy.

By using such scheme, it is threaded to and is detachably fixed connection, when pile is placed on layboy, first The limited post of side is unloaded, pile is directly placed into heap paper space from this side, then reinstalls limited post, is easy to put Pile is put, it is convenient and swift.

Preferably, limited post upper end is bent outwardly to form guide part.

By using such scheme, guide part is oriented to placing pile, and adsorbent equipment first is moved on into paper feeding along slide rail Platform side, pile is put into above limited post, pile slides along guide part, is gradually directed in heap paper space, places pile It can not align heap paper space and be stuck in limited post upper end.

Preferably, guide part upper end is connected with magnetite, magnetite is engaged with pressure ring.

By using such scheme, when placing paper, pressure ring is slid onto guide part upper end, magnetite absorption pressure ring is so as to solid Level pressure ring, such pressure ring do not interfere with pile and are put into heap paper space, are easy to place pile, after the completion of heap paper, by pressure ring again It is slid onto on limited post downwards, continues to push down pile edge.

Preferably, pressure ring side is into spherical shape.

By using such scheme, pile is pushed down using the side of spherical shape, reduces the contact area of pressure ring and heap paper, After absorption picks up paper, paper edge is globally slid, be easy to take out paper under pressure ring.

In summary, the utility model has the advantages that：Pile edge is pushed down by pressure ring, prevents a piece of paper The paper below when being pulled away is opened to be driven；By being arranged pressure ring, pressure ring is allowed to be slid on limited post, whenever paper is adsorbed device After siphoning away, continue to push down the edge of next paper, ensure the smooth of pile；By setting guide part and magnetite, magnetite is located at Guide part upper end and the pressure ring of adsorbing metal, it is easy to be placed on layboy from guide part by pile.
