The specific embodiment
As shown in Figure 1,5, cylinder 1 two ends of the breadth adjustable digital printing cylinder in the present invention are bearing in axle sleeve 3 by bearing 2, and axle sleeve 3 is connected and fixed with wallboard 4.
As shown in Figure 2,3, the tooth mechanism of holding in the month of intermediate roll 1 of the present invention adopts 5 structures that combine with vacuum slot 6 of gritting one's teeth, wherein, the front end of cylinder 1 is installed the mechanism of gritting one's teeth, grit one's teeth and 5 coordinate the interlock top of form with bite-block by the mechanism of gritting one's teeth some, the cylinder afterbody arranges vacuum slot mechanism, some 6 absorption paper end pins of the vacuum slot along the cylinder axial distribution in vacuum slot mechanism.
The mechanism of gritting one's teeth: it comprises the bite-block axle be arranged in parallel and the axle of gritting one's teeth, and bite-block axle and the axle of gritting one's teeth be along the axial setting of cylinder, and the bite-block axle is along the some bite-blocks of its axial distribution, correspondingly on the axle of gritting one's teeth is equipped with one group and grits one's teeth; As shown in Figure 3,4, the end of the axle of gritting one's teeth arranges and opens tooth fork 51, and the spin 52 of opening on tooth fork 51 is close to all the time opening on tooth cam 53 of cylinder end under the effect of the axle torsion spring of gritting one's teeth.
Thereby the height by opening tooth cam 53 and the purpose of controlling 5 the folding of gritting one's teeth coordinating of fork spin 52 and reach the paper handing-over.It will be appreciated by those skilled in the art that the mechanism of gritting one's teeth here is exemplary, is not restrictive.
Vacuum cup mechanism: it comprises some vacuum slots 6, and vacuum slot 6 is arranged on the afterbody of cylinder 1, and along cylinder 1 axial distribution; The end gas port of vacuum slot 6 is communicated with the tracheae 7 on being arranged in cylinder 1, and tracheae 7 is connected with external gas source with can bleed.
Cylinder 1 is in when action, and sealing shroud 8 is fitted in outside axle sleeve 3 all the time, by external gas source by axle sleeve air flue, sealed air-space, tracheae to the vacuum slot generation negative pressure of bleeding; After the tail of paper slightly passes through interface point, held the end pin of paper by vacuum slot.
The axial and circumferential breadth of the cylinder in the present invention all adopts adjustable structure.
Afterbody vacuum slot absorption breadth adjustable structure: change the absorption breadth by the keying quantity that controls the afterbody vacuum slot and realize.As shown in Figure 6,7,
Each vacuum slot 6 all is inserted with keying control plate 101 with the junction of tracheae 7, opens and closes control plate 101 and has an open/close through hole 104, opens and closes control plate 101 and realizes that by the position of control open/close through hole vacuum slot 6 is communicated with or closes with tracheae 7.
Be communicated with stability for improving vacuum slot 6 with tracheae 7, open and close control plate 101 and also have a locating hole, each vacuum slot 6 one sides all arrange the locking ball 103 with spring 102, and locking ball 103 can embed and open and close in the locating hole 105 of controlling plate.When locking ball 103 embeds locating hole 105, open/close through hole 104 is by vacuum slot 6 and tracheae 7 conductings.
The circumferential breadth adjustable structure of cylinder: times footpath impression cylinder of take in the present embodiment is example, as shown in Fig. 2,12,
The cross-coincidence that breadth adjustment block 12 and cylinder body 11 can be adjusted both comb structures by the adjustment block rotating mechanism realizes that circumferential breadth changes.
The adjustment block rotating mechanism is specially: be provided with one section tooth piece 14 concentric with cylinder on breadth adjustment block 12, on wallboard 4, arranging can axially movable regulating shaft 15, regulating shaft 15 front ends arrange adjusting gear 16, and the dowel hole 17 of two axial distribution is installed on regulating shaft 15.Size according to the paper breadth, when circumferential breadth need to change, unclamp four set bolts 18 that are connected in kidney slot 19 of breadth adjustment block 12 and cylinder body 11, the taper pin of extracting in inboard dowel hole is put into outside dowel hole, promote to the inside that adjusting gear 16 makes it and tooth piece 14 engagement, by spanner, rotates and adjust gear 16 and make 14 rotations of tooth piece.Because tooth piece 14 is fixing with adapter sleeve 13 and breadth adjustment block 12, so breadth adjustment block 12 is and then rotated, the bolt 18 that is tightened again after adjustment, realize the increase of the circumferential breadth of cylinder or reduce.
It will be appreciated by those skilled in the art that in the present embodiment, the adjustment block rotating mechanism is only exemplary, is not restrictive.In addition, inevitable, cylinder, when adopting this kind of circumferential adjustable structure, is grited one's teeth and is arranged on cylinder body front end neutral place, and vacuum slot is arranged on the breadth adjustment block.
Operation principle:
When axially breadth is adjusted, only need pull the keying at vacuum slot place to control plate, open/close through hole is left to the vacuum slot place, can close this vacuum slot.
When circumferentially breadth is adjusted, the tooth piece driven on the breadth adjustment block by adjusting gear rotates, and then drives the breadth adjustment block to rotate, and makes the comb structure of breadth adjustment block move between the broach of cylinder body, changes both cross-coincidence degree; And then realize the change that cylinder is grited one's teeth with the vacuum slot creep distance.
