Abstract

The color template roller includes central support shaft, and color template rings. The central support shaft is provided with axial guide structure, and the color template rings around the central support shaft may be guided by the guide structure to slide along the shaft and locked with the locking screws. Furthermore, the central support shaft may be provided with axial color template ring regulating mechanism and the color template rings may be provided with radial color template ring regulating mechanism, so as to regulate color template rings axially and radially. Compared with available integral color template, the present invention fines the regulation of color template surface for precise over printing.

Description

A kind of look masterplate cylinder

Technical field

The present invention relates to a kind of look masterplate cylinder.

Background technology

Used look masterplate cylinder is divided into two kinds on the money press at present: a kind of is the outstanding masterplate of direct engraving on barrel, and another kind is that two kinds of look masterplate cylinders are overall structure at the whole look masterplate of barrel outsourcing lastblock (claiming " tabular look masterplate " again).When carrying out the chromatography printing and need adjust to the position of version, must whole traveling roller for first kind of look masterplate cylinder, then must whole mobile look masterplate for second kind of look masterplate cylinder.Because the forme on the relief printing plate cylinder must be corresponding mutually with the look masterplate, therefore, the mode of this adjustment look masterplate position, glue, gravure printing operation have been passed through for those, and produced the paper of irregular distortion, be difficult to obtain gratifying chromatography effect, particularly each zonule on the paper all had the banknote printing of cover alignment request, its printing quality is difficult to guarantee especially.

Summary of the invention

Deficiency at prior art exists the purpose of this invention is to provide a kind of new look masterplate cylinder, and the position of the look masterplate on this cylinder can be along the two-way adjustment of cylinder circumferential and axial, thereby satisfies the requirement of accurate overprinting.

For achieving the above object, look masterplate cylinder of the present invention comprises central support shaft, color mould ring, central support shaft is provided with axially directed structure, several color mould rings are sleeved on the central support shaft, and color mould ring can be in the lower edge central support shaft slip of described guide frame guiding and by the lock-screw tightening.

Further, described guide frame is gathering sill or feather key.

Further, described color mould ring is an overall structure, and look masterplate direct engraving on its outer surface.

Further, described color mould ring comprises look masterplate, slip ring seat, and the look masterplate is rotatable to be sleeved on the slip ring seat.

Further, described look masterplate is fixed on the slip ring seat by fixed platen.

Further, described look masterplate is made of masterplate and bracing ring.

Further, also be provided with color mould ring axial adjustment structure on the described central support shaft, this axial adjustment structure is made of retainer ring and adjustment screw, retainer ring slidably is sleeved on the described central support shaft and by holding screw and fixes, be provided with several adjustment screw on each retainer ring, the masterplate circle of the same colour of retainer ring clamping in twos is by the axial location of the adjustment of the adjustment screw on it color mould ring.

Further, be provided with circumferential micro-adjusting mechanism between described look masterplate and the described slip ring seat, this mechanism is made of a pair of pitch wheel, one of them gear is concentric fixing with described slip ring seat, this gear also can directly be made on the slip ring seat, and another gear is installed on the described look masterplate.

To have whole look masterplate now is substituted by several color mould rings, and each color mould ring is all made axially, circumferentially after all adjustable structure, refinement the adjustable extent of look masterplate face, each color mould ring all can together be adjusted according to the local deformation situation of paper accordingly with the forme on the relief printing plate cylinder, thereby satisfied all requirements of the accurate alignment of needs of each zonule of paper, overcome the defective of prior art.

The specific embodiment

Among Fig. 1, embodiment illustrated in fig. 21, look masterplate cylinder is made of central support shaft 1 and 5 color mould rings 2, central support shaft 1 is provided with feather key 3, color mould ring 2 is sleeved on the central support shaft 1, and can slide in the guiding lower edge of feather key 3 central support shaft, color mould ring 2 is provided with holding screw 5, can be fixed on central support shaft 1 axial arbitrary position by holding screw 5 color mould rings 2.Color mould ring 2 is made of look masterplate, two fixed platen 23, slip ring seat 24, and wherein masterplate 21 and the bracing ring 22 made by rubber-plastics material of look masterplate constitutes, and two fixed platen 23 are clamped to bracing ring 22 on the slip ring seat 24 by screw 25.Unclamp screw 25, the look masterplate can rotate around slip ring seat 24.Central support shaft 1 two ends have the taper spindle nose, and an end has key 4, and look masterplate cylinder is assemblied on the printing machine by central support shaft 1 and key 4.

Masterplate 21 also can be made by hard material (as metal material), in order to guarantee the ink transfer quality between masterplate 21 and the relief printing plate cylinder (not shown), only need guarantee to have between the two enough difference of hardness and get final product with the relief printing plate cylinder by softer material manufacturing.

Fig. 3, Figure 4 shows that the 2nd kind of embodiment of the present invention, in this embodiment, central support shaft 1 is provided with the color mould ring axial regulating mechanism that is made of retainer ring 28 and adjustment screw 29, retainer ring 28 is fixed on the central support shaft by holding screw 30, adjustment screw 29 ends on it lean on slip ring seat 24, after unclamping holding screw 5, can finely tune the axial location of slip ring seat 24 by adjustment screw 29.The look masterplate is made of masterplate 21 and bracing ring 22 thereof equally, be provided with circumferential micro-adjusting mechanism between look masterplate and the slip ring seat 24, this micro-adjusting mechanism is made of a pair of pitch wheel, and wherein pinion 26 is installed on the bracing ring 22, and gear 27 is directly made on slip ring seat 24.Unclamp screw 25, finely tune by can the check colors circumferential position of masterplate of swing pinion 26.

Fig. 5 is a look masterplate cylinder confined state schematic diagram of the present invention, and two look masterplate cylinder C are pressed on the relief printing plate cylinder D, and the structure of relief printing plate cylinder D and look masterplate cylinder C are complementary.After the forme on the relief printing plate cylinder D is suitably adjusted according to the paper distortion situation, unclamp holding screw 5 and screw 25 on the color mould ring 2, the corresponding adjustment done in the position of the masterplate of checking colors, so that it is accurately aimed at forme.

The above-mentioned look masterplate that separates can satisfy the printing that each zonule on the paper is all had the banknote of cover alignment request, particularly to passing through glue, gravure printing, produces the paper of irregular distortion, has more accurate alignment.
