The specific embodiment
Explain the present invention below in conjunction with accompanying drawing and specific embodiment:
See also Fig. 1, the forme of flexible printing machine of the present invention comprises a substrate 1 and two strip metals extension limit 2,3.Wherein:
Substrate 1 is made by resin material, and one side is carved with picture and text; The length of the plate cylinder of the width of this substrate 1 and adagio printing machine is adaptive, and the girth of the outer surface of the plate cylinder on the length of substrate 1 and the adagio printing machine is adaptive;
Two strip metals are hung limit 2,3 are a bending plate with stationary plane and installed surface, they are connected to two of substrate 1, this two strip metal is hung limit 2,3 length is identical with the width of substrate 1, two strip metals are hung limit 2,3 stationary plane respectively by adhesive on two edge surface that the figure of substrate 1 tattoos the face, first metal that is positioned at 1 one of substrates hangs the stationary plane on limit 2 and the angle α of installed surface is an acute angle, preferably get 50 °～55 °, second metal that is positioned at substrate 1 other end hangs the stationary plane on limit 3 and the angle β of installed surface is the obtuse angle, preferably gets 130 °～140 °;
Offer a locating slot 22,32 on the free end of the length central authorities of the installed surface on first metal extension limit 2 and second metal extension limit 3;
Offer some locating holes 21,31 respectively on the installed surface on first metal extension limit 2 and second metal extension limit 3.
Locating hole 21,31 and locating slot 22 that two strip metals are hung on the limit 2,3 are being made a plate and are being lockd up the effect that can both play the location in the process.During plate-making, with the pin location back plate-making on locating hole 21,31 and the locating slot 21 insertion plate-making frocks; When locing up, with the alignment pin on locating hole 21,31 and the locating slot 22 insertion plate cylinders, the accurately position of positioning block on plate cylinder.
The forme of flexible printing machine of the present invention just can be installed on the plate cylinder with reference to the link plate mode of the forme of offset press when mounted.
See also Fig. 3 a, Fig. 3 b, Fig. 3 c and Fig. 4 and Fig. 5 again, the installation method of the forme of flexible printing machine of the present invention is used for above-mentioned forme of the present invention is installed in plate cylinder, and this installation method may further comprise the steps:
Step 1, on the outer peripheral face of the plate cylinder 4 of adagio printing machine, offer a mounting groove 41, the width of the installed surface on the two strip metals extension limit 2,3 of the degree of depth of this mounting groove 41 and forme is adaptive, and the angle of the two side of this mounting groove 41 and the tangent line of notch is α, is 50 °～55 °;
Step 5, the installed surface that will be arranged in second metal extension limit 3 of forme other end is embedded in the mounting groove 41 of plate cylinder 4, and the locating slot 32 that second metal is hung on the limit 3 is inserted on the alignment pin 42.
Because plate cylinder 4 can produce centrifugal force when rotating, and the angle of the tangential direction of the two side of the mounting groove 41 that method of the present invention is offered on plate cylinder 4 and notch is less than 90 °, therefore can avoid forme to deviate from, thereby guarantee the forme installation firmly from plate cylinder 4.
The installation method of the forme of flexible printing machine of the present invention can be dismantled plate cylinder and just can realize locing up, thereby the plate change time can be saved greatly, and the precision of locing up can lean on locating slot and the locating hole offered on the metal extension limit to guarantee, irrelevant with human factor (as justifier's experience), can also not re-use expensive double faced adhesive tape and come the sticking flexible forme, therefore can reduce production costs greatly.
