Transfer.Laser transfer membrane can enter from the first transfer roller side above coining platform, rap around to receipts from the second transfer roller side
Winding apparatus is wrapped on Scroll.Actuating mechanism can be roller platen or stamping station, for example, can be by being set to first
Roller platen on the right side of transfer roller is imprinted or the transfer roller of direction of feed also serves as roller platen, need to also be on coining platform
Row ultra-violet curing, these are it will be apparent to those skilled in the art that I will not elaborate moulding process.Transfer roller and roller platen can
To be driven by driving motor.
When stamp transfer, firstly, the laser transfer membrane of laser pattern is had on placing on laser transfer membrane unwinding device,
And make the laser pattern of laser transfer membrane facing towards printed matter；Then, by printed matter input mechanism, make stamp transfer machine and each
Kind printing machine connects, in this way, the printed matter for being printed on UV-light photocuring ink of printing machine output, it will be by printed matter input mechanism
It is conveyed to the eindruckwerk of stamp transfer device, eindruckwerk is by the laser pattern face of laser transfer membrane and the ultraviolet light of printed matter
Light consolidates ink or gloss oil face pressure is closed, and is stamped in laser pattern on UV-light photocuring ink or gloss oil；Then, it presses together
Laser transfer membrane and printed matter are conveyed to mechanism for stripping by conveying mechanism, in conveying mechanism transmission process, above conveying mechanism
Ultraviolet gloss oil curing mechanism ultraviolet gloss oil solidification is carried out to the laser transfer membrane and printed matter that press together；Ultraviolet gloss oil is solid
After change, mechanism for stripping removes laser transfer membrane and printed matter, in this way, just stamp transfer arrives the laser pattern on laser transfer membrane
On printed matter, laser transfer membrane after removing is recycled by laser transfer membrane recycling wrap-up, the printed matter after removing by
Printed product output mechanism is conveyed to printed product intermediate carrier structure or die-cutting apparatus；Cross cutting rim charge is carried out after cross cutting to remove back
It receives and cross cutting product is collected.The process of transfer is techniques known, is no longer explained further here.
What the automatic change of lap of unwinding device was realized in.Firstly, being by three unreeling shafts in normal operation
Any one be in operating position, for example, be located at the rightmost side or near coining platform side.It is put for example, working as first
When spool 212 is in operating position, other two unreeling shafts are in stand-by state, the first unreeling shaft 212, the second unreeling shaft 213
Between the first linking roller 215 it is standby, is wound with linking band on the outside of the first linking roller, linking band can be single layer
Ring-type has opening, is also possible to multilayer Weak link.Transfer film front end on second unreeling shaft 213 is bonded in linking band
On latter half.At the end of the transfer membrane use on the first unreeling shaft 212 (for example transfer membrane end is measured by sensor
End of identification or when measuring transfer layer tension by tension sensor and being more than predetermined value, different transfer membrane needs targetedly
Setting, this is that those skilled in the art are easy to accomplish, and I will not elaborate), for driving the driving mechanism control of switching shaft 211
Switching shaft processed rotates predetermined angular counterclockwise so that linking roller 215 move upwards, the first half of splicing tape thereon with
Transfer membrane is pressed against each other and is bonded, so that the front half section for completing splicing tape on linking roller is mutually be bonded with a upper transfer membrane, after
Half section mutually be bonded with second transfer membrane, realizes the connection of front and back transfer membrane.The transfer membrane to bond together is located in linking roller
It stretches next, it is unfolded outward in driving linking roller 215 (for example, being as shown in Figure 3 undeployed configuration, after expansion side
Linking roller 215 is substantially vertical or near vertical with the axis of switching roller) its second position is reached, due to viscous on linking roller 215
Weak link (connection breaking) between any two sections of tape splicing, only a little pulling force can be broken, so, driving linking roller expansion
In the process, splicing tape Nian Jie with transfer membrane realization is detached from roller is connected.If the radium-shine transfer on the first unreeling shaft
The end virtual pressure of film is on the roller of transfer membrane, then without being cut, because it is located above the second unreeling shaft, so remaining transfer
Film, which is attached on the transfer membrane of the second unreeling shaft to continue to, to be terminated and is wrapped in recycling roll, suspends several weeks during switching
Still transfer film does not stop the coining of phase.If transfer membrane is fixed on its roller, need to unreeling shaft 212 be connected between axis 215
Setting laser cutting or gas cutting equipment are detached to make to have been used up the transfer film on unreeling shaft, but such situation is less.
Next, further rotating switching shaft, three unreeling shafts is driven to rotate counterclockwise, so that the second unreeling shaft arrives
Up to operating position, the first unreeling shaft returns to the reel change position of upper left, and the shell of radium-shine transfer is arranged at reel change position to be beaten
The cover board opened, staff, which raises cover board, can be carried out reel change, and in change of lap, the front end portion of transfer membrane is pulled out one
Section is bonded in the second half section of the splicing tape on the linking roller between the first unreeling shaft and third party's spool, and will in change of lap
The linking roller of expansion (or rotate close to 90 degree) is being recovered to parallel with switching shaft, returns to its first position.It is connected the exhibition of roller
Opening can be by being connected to the support rod 218 being connected between roller root 216 and side connecting rod 217 in side connecting rod 217
On movement realize, be provided with sliding slot in side connecting rod 217,218 one end of support rod be located in sliding slot the other end be connected
Roller is fixed, and when needing to be unfolded, drives side connecting rod 217 to close to linking roller side by driving motor or other driving equipments
Mobile (moving up in Fig. 3), when withdrawal, are on the contrary.It should be noted that needing to suspend the print in several periods in reel change
Brush, the transfer film when newly roll up restart printing when transfer station is completely covered again, and in reel change, and adjustable turn
Print roller makes the distance between itself and transfer platform are appropriate to increase, to allow more smooth change of lap and splicing tape is avoided to be stuck between transfer roll
In gap.
The construction of laser transfer membrane recyclable device can be identical as the construction of unwinding device, and only removal process does not need that
Sample is complicated, because without the concern for the linking of two transfer films.For example, laser transfer membrane wrap-up include the second switching shaft,
First Scroll, the second Scroll, for the second switching shaft between the first Scroll and the second Scroll, two Scrolls are in pair
Claim setting, be arranged in parallel with the second switching shaft, the rotation of the second switching shaft can drive two unreeling shaft synchronous rotaries, and first receives
Spool and the second Scroll work alternatively, and the Scroll surface in stand-by state is equipped with the outward-facing bonding of bonding in advance
Cutter device is arranged between the first Scroll and the second Scroll in band.By taking the arrangement in subsequent embodiment as an example, original state
Under, the Scroll in work is in left side, another is located at right side and rotates clockwise switching shaft when needing replacing Scroll
It is Nian Jie with transfer membrane from lower part around coming up so that the Scroll on right side rotates clockwise, then, pass through gas using cutter device
Cut, machine cuts or laser cutting cut transfer membrane along new Scroll edge, realize the replacement of Scroll.In addition, can
Two parts after transfer film stripping are recycled respectively respectively so that two wrap-ups are arranged.
Since the key continuously unreeled is that unwinding device, each Scroll can wind more transfer membranes, so i.e.
Just common wrap-up is used, as long as unreeling continuously, as long as Scroll is allowed to carry out more multiple-turns wound, so that it may lasting to receive
Volume, but difference is unreeled, the specification of every migration volume film is all standard, and being finished must replace.
