Printing plate roller 93 is the device commonly used in the printing process, and its surface adhesion is the printing ink in the conventional use process only, in the embodiment of the utility model provides an it constantly supplements the rubber coating to printing plate roller 93 surface through rubber coating roller 94, also can adopt UV drying lamp 92 to be used for carrying out preliminary drying to the adhesive layer after the rubber coating and fix certainly.

Second embodiment of the glue spreading device 9, as shown in fig. 2, the glue spreading device 9 includes a glue spreading nozzle 91 disposed on the periphery of the paper transfer roller 10, and a UV drying lamp 92 disposed on the periphery of the paper transfer roller 10 for drying the substrate after glue spreading. The gluing nozzle 91 is connected with a device for storing gluing, the gluing nozzle 91 is controlled by a numerical control system, gluing patterns corresponding to gold stamping patterns can be accurately sprayed on a printing stock, and the UV drying lamp 92 is used for primarily drying and fixing the adhesive layer to prevent the adhesive layer from being in a flowing state.

In some embodiments, as shown in fig. 1, an angle sensor 12 is disposed on each of the gold stamping cylinder 3 and the imprinting cylinder 4, a photoelectric sensor 13 is disposed at a feeding port between the gold stamping cylinder 3 and the imprinting cylinder 4, and an axial driving mechanism 14 is disposed at an end position of the gold stamping cylinder 3 or the imprinting cylinder 4. The photoelectric sensor 13 is used for collecting the position of a gold stamping pattern on a gold stamping film and the position of a glue coating pattern on a printing stock, so that when the gold stamping roller 3 and the stamping roller 4 are pressed, the gold stamping pattern and the glue coating pattern are aligned in registration, if the information collected by the photoelectric sensor 13 proves that the gold stamping pattern and the glue coating pattern cannot be aligned in registration, the rotation angle of the gold stamping roller 3 or the stamping roller 4 needs to be adjusted by combining the information collected by the angle sensor 12, and the axial driving mechanism 14 is used for adjusting the axial position of the gold stamping roller 3 or the stamping roller 4, so that the printing stock is aligned with the gold stamping film in.

In some embodiments, as shown in fig. 3, the impression cylinder 4 is provided with a gripper 42 and a pad 43 which are mutually matched, the impression cylinder 4 is provided with a groove 41 for arranging the gripper 42, the pad 43 is arranged on a groove wall of the groove 41, and when the pad 43 is matched, the outer surface of the gripper 42 is lower than the outer peripheral surface of the impression cylinder 4 or is flush with the outer peripheral surface of the impression cylinder 4. The fixing device on the impression cylinder 4 can adopt a conventional gripper structure, but when the fixing device is specifically arranged, the outer surface of the gripper 42 is ensured not to exceed the outer peripheral surface of the impression cylinder 4, so that the pressing of the impression cylinder 4 and the gold stamping cylinder 3 is influenced, and of course, an air suction negative pressure adsorption structure can be adopted to adsorb a printing stock for pressing later.

The following description is given with reference to specific examples:

aiming at a single printing stock, firstly, a gripper on a paper transfer roller 10 works to grip the printing stock by a production line, the printing stock is accurately coated with glue on the surface of the printing stock by a gluing device 9 in the process of rotating on the paper transfer roller 10, after the glue is coated, the printing stock is transferred to an imprinting roller 4 by a reversing roller 11, the gripper on the imprinting roller 4 drives the printing stock to the tangent position of the imprinting roller 4 and a stamping roller 3, at the moment, a photoelectric sensor 13 collects the position of a stamping pattern on a stamping film and the position of a gluing pattern on the printing stock, if the positions of the printing stock and the gluing pattern do not correspond, the rotation angle of the stamping roller 3 or the imprinting roller 4 is controlled and adjusted by combining an angle sensor 12, meanwhile, an axial driving mechanism 14 adjusts the axial position of the imprinting roller 4, then the gripper is opened and put down to press the printing stock and the stamping film, and when the stamping film comes out from a discharge hole, the printing stock can be adhered to the gold stamping film under the action of the adhesive layer, the printing stock continues to move forward, the cooling device 5 can also cool the gold stamping film and the printing stock, the adhesive layer is gradually solidified and adhered to the printing stock in the process, finally, the gold stamping pattern is completely pressed and stamped on the printing stock, the printing stock falls on the conveyor belt 6 and is collected under the action of the stripping device 15, it needs to be noted that the tail end of the single printing stock does not extend to the position of the gripper, and the position of the gripper does not play a role in pressing and stamping with the gold stamping roller 3 at the moment, so the effective pressing and stamping circumference of the imprinting roller 4 is larger than the length of the single printing stock; when the next printing stock is pressed, the pressing roller 4 continues to rotate to hold the next printing stock, the gold stamping roller 3 also continues to rotate, the gold stamping film is prevented from going forward to cause waste, the gold stamping film is pulled back or suspended reversely under the traction of the feeding roller 1 to wait for the next printing stock, and then the photoelectric sensor 13 continues to work to judge the position of the gold stamping pattern on the gold stamping film and the position of the glue coating pattern on the printing stock.

For continuous printing stocks, the stamping roller 4 at the moment should not be provided with a fixing device for holding the printing stocks, because the paper is continuous, the position of the fixing device can influence the pressing effect of the stamping roller 4 and the stamping roller 3, and the adopted method can firstly manually pull a section of the printing stocks to a discharge hole between the stamping roller 4 and the stamping roller 3 and then start to operate.

The device can also be used for a C square gold stamping process, namely, only concave-convex patterns are arranged on a gold stamping film without a release layer and an aluminum coating, firstly, a printing stock is coated with glue by a gluing device 9, then, an imprinting roller 4 and a gold stamping roller 3 start to work for pressing and stamping the printing stock with the glue coating, the softened adhesive layer on the surface of the printing stock is pressed into the concave-convex patterns by the gold stamping film, then, the printing stock is peeled off, and thus, the adhesive layer on the printing stock can present a three-dimensional holographic effect under the bright condition.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
