Description

Technical Field

[0001] The present invention relates to the field of molding technology, and particularly relates to a device and a manufacturing method for a mold roll. Background Art

[0002] Current optical anti-counterfeiting products, such as optical thin films for banknotes, credit cards, and passports, anti-counterfeiting labels for commodities, packaging, etc. Generally, the UV imprinting (or molding) process is used to copy the micro-structure from the surface of the imprinting plate roll to the plastic film.

[0003] In the related art, the imprinting plate roll generally uses a nickel plate with a micro-structure wrapped around the roll blank for imprinting production. During the production of the imprinting plate roll, the nickel plate needs to be wrapped around the roll blank and welded and fixed. However, due to the need for welding and fixing, a part for welding needs to be reserved in advance, so there will be problems such as a large perimeter error of the nickel plate sleeve and a large weld width, which affect the imprinting work of the imprinting plate roll. Summary of the Invention

[0004] In view of this, the present invention provides a device and a manufacturing method for a mold roll to solve the problems that the perimeter error of the nickel plate sleeve is large, the weld width is large, and it affects the imprinting work of the imprinting plate roll.

[0006] A master plate, on the end face of the master plate facing the to-be-processed plate roll, a micro-structure pattern is provided;

[0007] A shielding structure, covering the end face of the master plate facing the to-be-processed plate roll. A printing port is opened on the shielding structure. The printing port matches the micro-structure pattern. The printing port is adapted to receive the micro-structure pattern in the printing port. There is a glue solution in the printing port. The glue solution covers the micro-structure pattern. The glue solution and the printing port are configured as a printing station. The to-be-processed plate roll is adapted to move at the printing station to print the micro-structure pattern on the surface of the to-be-processed plate roll through the glue solution.

[0008] In an optional embodiment, it further includes:

[0009] A cutting assembly, the cutting assembly is arranged at the upper end of the shielding structure. The cutting assembly is adapted to cut the shielding structure so that the shielding structure has the printing port.

[0010] In an optional embodiment, it further includes:

[0011] The glue curing assembly is arranged at the bottom of the master plate. The glue curing assembly includes a curing light source, and the output end of the curing light source faces the master plate. The master plate is a transparent master plate. The shielding structure is adapted to shield the light of the curing light source so that the light of the curing light source acts on the surface of the to-be-processed plate cylinder through the printing station.

[0012] In an optional embodiment, the cutting assembly includes a detection unit, a cutting member and a controller. The detection unit and the cutting member are respectively signal-connected to the controller. The controller is adapted to obtain the signal of the detection unit to control the cutting member to cut the shielding structure.

[0013] In an optional embodiment, it further includes:

[0014] A driving assembly, which is connected to the to-be-processed plate cylinder to drive the to-be-processed plate cylinder to move at the printing station.

[0015] In an optional embodiment, the shielding structure is any one of a film and aluminum foil.

[0016] In an optional embodiment, the glue is UV glue.

[0017] In an optional embodiment, the curing light source is a UV lamp. The light of the UV lamp can act on the surface of the to-be-processed plate cylinder through the printing station to solidify the glue on the surface of the to-be-processed plate cylinder and fix the microstructure pattern.

[0018] In a second aspect, the present invention further provides a method for manufacturing a profiled plate cylinder, which is carried out based on the profiled plate cylinder manufacturing device described in any one of the above solutions, and includes the following steps:

[0019] Fix the master plate;

[0020] Take a shielding structure and cover the shielding structure on the master plate;

[0021] Cut out a printing port on the shielding structure. The printing port houses the microstructure pattern on the master plate inside the printing port. Then, lay glue inside the printing port so that the glue covers the microstructure pattern, and the printing port and the glue constitute a printing station;

[0022] The to-be-processed plate cylinder moves inside the printing station, so that the microstructure pattern is printed on the surface of the to-be-processed plate cylinder through the glue.

[0023] In an alternative embodiment, before cutting the printing port, the cutting assembly needs to first obtain information on whether there is an occlusion structure on the master plate and obtain the position information of the micro-structure pattern on the master plate. After obtaining the information on the occlusion structure and the position information of the micro-structure pattern on the master plate, the cutting assembly cuts the printing port on the occlusion structure and makes the printing port accommodate the micro-structure pattern within the printing port.

[0024] Beneficial effects:

[0025] 1. For a device for manufacturing a corrugated plate roller provided by the present invention, by adopting the scheme of printing the micro-structure pattern on the master plate with glue and bonding it to the surface of the to-be-processed plate roller, the problem of a relatively large weld width of the nickel plate is avoided. At the same time, a printing port for accommodating the micro-structure pattern is provided on the occlusion structure, and the perimeter of the printing port is the length required for the to-be-processed plate roller to imprint and cure the micro-structure for one week. Thus, the to-be-processed plate roller can be made into a seamless imprinting plate roller, achieving the purpose of adjusting the outer perimeter of the plate roller with micro-structures, ensuring the integrity of the imprinting surface of the imprinting plate roller, and also ensuring the imprinting work of the pressing plate roller.

[0027] 3. For a device for manufacturing a corrugated plate roller provided by the present invention, the light of the curing light source is blocked by the occlusion structure, so that the light of the curing light source can only act on the printing station, avoiding the glue on the occlusion structure from solidifying and connecting into one body along with the glue in the printing station. At the same time, it also avoids adding a step of cutting the redundant part, which is beneficial to ensuring the integrity of the imprinting surface of the imprinting plate roller and improving the manufacturing efficiency.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0034] The following combines Figure 1 and Figure 2 to describe the embodiments of the present invention.

[0035] According to an embodiment of the present invention, on the one hand, a device for manufacturing a profiled plate roller is provided, including a master plate 1 and a masking structure 3.

[0036] Specifically, the end face of the master plate 1 facing the plate roller 4 to be processed is provided with a microstructural pattern. The masking structure 3 covers the end face of the master plate 1 facing the plate roller 4 to be processed. A printing port 5 is formed on the masking structure 3. The printing port 5 matches the microstructural pattern. The printing port 5 is adapted to accommodate the microstructural pattern therein. An adhesive solution 2 is provided in the printing port 5. The adhesive solution 2 covers the microstructural pattern. The adhesive solution 2 and the printing port 5 are configured as a printing station. The plate roller 4 to be processed is adapted to move at the printing station to print the microstructural pattern on the surface of the plate roller 4 to be processed through the adhesive solution 2.

[0037] In this embodiment, the master plate 1 is placed on a workbench. The plate roller 4 to be processed is arranged above the master plate 1. The upper end face of the master plate 1 is provided with a microstructural pattern. The masking structure 3 covers the upper end face of the master plate 1. A printing port 5 is formed on the masking structure 3. The printing port 5 is located at the microstructural pattern. The printing port 5 can accommodate the microstructural pattern therein, and the perimeter of the printing port 5 is the length required for the plate roller 4 to be processed to imprint and cure the microstructures for one week. An adhesive solution 2 is laid in the printing port 5 so that the adhesive solution 2 covers the upper end of the microstructural pattern. The printing port 5 and the adhesive solution 2 covering the microstructural pattern together constitute a printing station. The plate roller 4 to be processed can be moved above one side of the printing station and vertically lowered to abut against the masking structure 3. The plate roller 4 to be processed can rotate and move from one side of the printing station to the other side. The adhesive solution 2 in the printing station will adhere to the surface of the plate roller 4 to be processed, so that the microstructural pattern on the master plate 1 is printed on the surface of the plate roller 4 to be processed through the adhesive solution 2.

[0038] It should be noted that by adopting the solution of printing the microstructure pattern on the master plate 1 with the glue solution 2 and bonding it to the surface of the plate cylinder 4 to be processed, the problem of a relatively large weld width of the nickel plate can be avoided. At the same time, a printing port 5 for accommodating the microstructure pattern is provided on the shielding structure 3. The perimeter of the printing port 5 is the length required for the plate cylinder 4 to be processed to imprint and cure the microstructure for one week. Thus, the plate cylinder 4 to be processed can be made into a seamless imprinting plate cylinder, achieving the purpose of adjusting the outer perimeter of the plate cylinder with microstructures, ensuring the integrity of the imprinting surface of the imprinting plate cylinder, and also ensuring the imprinting work of the pressing plate cylinder.

[0039] In some embodiments, it further includes: a cutting assembly. The cutting assembly is arranged at the upper end of the shielding structure 3, and the cutting assembly is suitable for cutting the shielding structure 3 to make the shielding structure 3 have the printing port 5.

[0040] In this embodiment, the cutting assembly is arranged at the upper end of the shielding structure 3. The cutting assembly can detect whether the shielding structure 3 exists on the master plate 1, and at the same time can also obtain the position of the microstructure pattern. After the cutting assembly detects that the shielding structure 3 covers the master plate 1 and obtains the position of the microstructure pattern, and inputs the length of the microstructure that the plate cylinder 4 to be processed needs to imprint and cure into the cutting assembly, the cutting assembly then moves above the position to be cut and cuts the shielding structure 3 to make the shielding structure 3 have the printing port 5.

[0041] It should be noted that by setting the cutting assembly, the shielding structure 3 can be cut better, reducing errors and improving the cutting accuracy, ensuring that the plate cylinder 4 to be processed can be made into a seamless imprinting plate cylinder.

[0042] In some embodiments, it further includes: a glue solution curing assembly. The glue solution curing assembly is arranged at the bottom of the master plate 1. The glue solution curing assembly includes a curing light source 6. The output end of the curing light source 6 faces the master plate 1. The master plate 1 is a transparent master plate 1. The shielding structure 3 is suitable for shielding the light of the curing light source 6 so that the light of the curing light source 6 acts on the surface of the plate cylinder 4 to be processed through the printing station.

[0043] In this embodiment, as Figure 2As shown, the workbench and the master plate 1 are a transparent workbench and a transparent master plate 1 respectively. The glue curing component is arranged at the bottom of the workbench. The glue curing component includes a curing light source 6. The curing light source 6 faces the master plate 1. The light of the curing light source 6 can pass through the workbench and the master plate 1 to cure the glue 2. During the process of the to-be-processed plate cylinder 4 moving from one side to the other side along one side of the printing station, a part of the glue 2 in the printing station will be extruded and move onto the shielding structures 3 on both sides of the printing station. The shielding structures 3 can block the light of the curing light source 6. The light of the curing light source 6 cannot penetrate the shielding structures 3 and can only act on the printing station. Therefore, the glue 2 adhered to the surface of the to-be-processed plate cylinder 4 solidifies under the action of the light of the curing light source 6, while the glue 2 on the shielding structures 3 does not solidify because the shielding structures 3 block the light of the curing light source 6.

[0044] It should be noted that by blocking the light of the curing light source 6 with the shielding structures 3, the light of the curing light source 6 can only act on the printing station, avoiding the glue 2 on the shielding structures 3 from solidifying and connecting together with the glue 2 in the printing station. At the same time, it also reduces the step of cutting the redundant part, which is beneficial to ensuring the integrity of the imprinting surface of the impression plate cylinder and improving the production efficiency.

[0045] In some embodiments, the shielding structure 3 is any one of a film and an aluminum foil.

[0046] Preferably, in this embodiment, the shielding structure 3 is a film. In other embodiments, the shielding structure 3 can be an aluminum foil or the like.

[0047] In some embodiments, the cutting component includes a detection unit, a cutting piece, and a controller. The detection unit and the cutting piece are respectively connected to the controller in a signal connection. The controller is adapted to obtain the signal of the detection unit to control the cutting piece to cut the shielding structure 3.

[0048] In this embodiment, the cutting assembly includes a cutting housing (not shown) and a driving structure (not shown). The driving structure is in signal connection with a controller (not shown). A detection unit (not shown) is arranged on the outer wall of the cutting housing and faces the master plate 1. A cutting member (not shown) is arranged at one end of the cutting housing facing the master plate 1. The controller is arranged inside the cutting housing. The detection unit can detect the position information of the micro-structure pattern on the master plate 1 and the information on whether there is an occlusion structure 3 on the master plate 1. The detection unit can transmit the information to the controller. If the controller receives the information that there is an occlusion structure 3 on the master plate 1, it controls the driving structure to drive the cutting housing to move above the occlusion structure 3, and according to the obtained position information of the micro-structure pattern, move above the micro-structure pattern. By pre-inputting the set size of the printing port 5 in the controller, when the cutting member moves above the micro-structure pattern along with the cutting housing, the controller controls the driving structure to drive the cutting member to move along the edge of the printing port 5 according to the set size of the printing port 5 and starts the cutting member to cut the occlusion structure 3. The size of the printing port 5 after cutting is the set size.

[0049] Preferably, in this embodiment, the cutting assembly is a femtosecond laser cutting machine to ensure that when cutting the occlusion structure 3, the master plate 1 will not be damaged.

[0050] In some embodiments, it further includes: a driving assembly. The driving assembly is connected to the to-be-processed plate cylinder 4 to drive the to-be-processed plate cylinder 4 to move at the printing station.

[0051] In this embodiment, the to-be-processed plate cylinder 4 is connected to a driving assembly (not shown). The driving assembly includes a pressing structure. The pressing mechanism can drive the to-be-processed plate cylinder 4 to move up and down. The controlled end of the pressing mechanism is connected to the controlled end of a control device (not shown). The driving assembly also has a motor (not shown) for driving the to-be-processed plate cylinder 4 to rotate. When the to-be-processed plate cylinder 4 abuts against one side of the printing station through the pressing structure, the motor drives the to-be-processed plate cylinder 4 to rotate and makes the to-be-processed plate cylinder 4 move from one side of the printing station to the other side, so that the adhesive 2 in the printing station adheres to the surface of the to-be-processed plate cylinder 4.

[0052] In other embodiments, when the to-be-processed plate cylinder 4 abuts against one side of the printing station through the pressing structure, the workbench can drive the master plate 1 to move relatively. Under the relative acting force, when the master plate 1 moves, it will drive the to-be-processed plate cylinder 4 to rotate, so that the adhesive 2 in the printing station adheres to the surface of the to-be-processed plate cylinder 4.

[0053] Preferably, in this embodiment, the adhesive 2 is UV glue.

[0054] Preferably, in this embodiment, the curing light source 6 is a UV lamp. The light of the UV lamp can act on the surface of the to-be-processed plate cylinder 4 through the printing station to solidify the adhesive 2 on the surface of the to-be-processed plate cylinder 4 and fix the micro-structure pattern.

[0055] The specific embodiments of the present invention will be elaborated in detail below in combination with a method for manufacturing an embossing plate roller according to the second aspect of the present invention.

[0056] It should be noted that a method for manufacturing an embossing plate roller according to the second aspect of the present invention is only a preferred embodiment of the present invention. The embossing plate roller of the present invention can be manufactured either by a method for manufacturing an embossing plate roller according to the second aspect of the present invention or by other methods. For the convenience of elaboration, the following will be elaborated by a method for manufacturing an embossing plate roller according to the second aspect of the present invention.

[0057] A method for manufacturing an embossing plate roller is carried out based on the embossing plate roller manufacturing device described in the above embodiment. The method includes the following steps:

[0058] S1. Fix the master plate 1 on the workbench.

[0059] S2. Take the shielding structure 3 and cover the shielding structure 3 on the master plate 1.

[0060] S3. Cut a printing port 5 on the shielding structure 3. The printing port 5 houses the micro-structure pattern on the master plate 1 therein. Subsequently, lay a glue solution 2 in the printing port 5 so that the glue solution 2 covers the micro-structure pattern. The printing port 5 and the glue solution 2 constitute a printing station.

[0061] S4. The to-be-processed plate roller 4 moves in the printing station, so that the micro-structure pattern is printed on the surface of the to-be-processed plate roller 4 through the glue solution 2.

[0062] In some embodiments, before cutting the printing port 5, the cutting component needs to first obtain information on whether there is a shielding structure 3 on the master plate 1 and obtain the position information of the micro-structure pattern on the master plate 1. After obtaining the information that there is a shielding structure 3 on the master plate 1 and the position information of the micro-structure pattern, the cutting component cuts the printing port 5 on the shielding structure 3 and makes the printing port 5 house the micro-structure pattern therein.

[0063] In this embodiment, the controller can obtain information on whether there is a shielding structure 3 on the master plate 1 and the position information of the micro-structure pattern on the master plate 1 through the acquisition detection unit. If the controller receives the information that there is a shielding structure 3 on the master plate 1, it controls the cutting piece to move above the micro-structure pattern, inputs the set size of the printing port 5 into the controller, and the controller cuts the printing port 5 according to the set size. The printing port 5 houses the micro-structure pattern therein.

[0064] In this embodiment, when laying the glue solution 2 in the printing port 5, the glue solution 2 can be laid after the cutting of the printing port 5 is completed. In other alternative embodiments, the glue solution 2 can also be continuously laid into the printing port 5 by a glue application device when the to-be-processed plate roller 4 moves from one side of the printing station to the other side.

[0065] In this embodiment, when the to-be-processed plate cylinder 4 moves within the printing station, the light of the curing light source 6 at the bottom of the workbench can pass through the printing station and act on the surface of the to-be-processed plate cylinder 4, causing the adhesive liquid 2 on the surface of the to-be-processed plate cylinder 4 to cure. The shielding structure 3 can block the light of the curing light source 6. The light of the curing light source 6 cannot penetrate the shielding structure 3 and can only pass through the printing station. The adhesive liquid 2 on the shielding structure 3 will not solidify because the shielding structure 3 blocks the light of the curing light source 6.

[0066] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations fall within the scope defined by the appended claims.
