This material is widely used in the packaging of products such as cigarette boxes, wine boxes, and cosmetic boxes. It not only enhances the market appeal of the products, but also provides strong support for brand protection due to its anti-counterfeiting characteristics.
[0003] The production process of holographic laser packaging materials includes several key steps, including UV coating, molding, UV curing, vacuum aluminum plating, lamination, etc. Among them, UV molding is a crucial link, which forms the desired holographic effect by pasting a flat nickel plate on the surface of the plate roller and molding the base film coated with the UV layer.
[0004] However, in the existing production technology, the nickel plate pasting operation in the UV molding process usually relies on manual work. Due to the nickel plate seams and the errors of the operators, the problem of inaccurate layout positioning often occurs, resulting in a reduced product qualification rate. Moreover, the problem of thick plate seams is also a common cause of rework, which not only affects production efficiency, but also increases production costs. In addition, repeated plate pasting processes will also lead to waste of nickel plate materials, increasing production costs.

[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0031] The molding system and control method with intelligent plate mounting and monitoring functions provided by the present invention are mainly used for molded anti-counterfeiting of printed products. Through the molding components, plate mounting components and plate monitoring components, the precise positioning and pasting of the plate can be ensured to avoid human errors. The working state of the molding plate roller can be monitored in real time, the use of the plate can be optimized, and the material waste caused by uneven thickness or plate wear can be reduced. In addition, the automated operation reduces manual intervention, shortens the production cycle, and improves production efficiency. The molding system and control method with intelligent plate mounting and monitoring functions provided by the present invention provide an innovative solution for the printing industry by integrating automation technology and intelligent monitoring systems. This solution not only improves production efficiency, but also conforms to the concepts of energy saving and environmental protection, leading the printing industry to develop in a more efficient and intelligent direction.
[0032] See also Figure 1 and Figure 2The present invention provides a molding system with intelligent plate mounting and monitoring functions, comprising: a molding component 1, a plate mounting component 2 and a plate material monitoring component 3. The molding component 1 comprises a molding plate roller 11 for molding preset images and texts on printed products. The plate mounting component 2 is arranged on one side or above the molding component 1, and the molded nickel plate 5 is pasted on the molding roller to form the molded plate roller 11. The plate material monitoring component 3 is arranged on the molding component 1 to detect the thickness of the printed product before and after molding and the depth of the photolithographic lines of the molded nickel plate 5. During the molding process, the molded nickel plate 5 is firstly accurately pasted on the molding roller to form the molded plate roller 11 by using the plate mounting component 2, and then the molded transfer of the image and text can be performed. During the molding process, the plate material monitoring component 3 plays its role, detecting the printed product before and after molding, and detecting the depth of the photolithographic lines of the molded nickel plate 5. This series of monitoring not only ensures the printing quality of the molding process, but also can evaluate the state of the molded nickel plate 5, such as wear or plate blockage. Through these monitoring data, the operator can make a decision to replace or clean the printing material in time, thereby ensuring the continuity of the printing process and the consistency of the printed product. The intelligent molding device of the present invention significantly improves the production efficiency and the quality of the molded product through automated and intelligent design.
[0033] The plate mounting assembly 2 includes a hot melt adhesive traction module 21, a cutting module 22, a plate mounting module 23 and an alignment module 24. The hot melt adhesive traction module 21 feeds the hot melt adhesive into the plate mounting module 23. The cutting module 22 cuts off the hot melt adhesive when the hot melt adhesive output by the hot melt adhesive traction module 21 reaches a set length. The alignment module 24 is arranged on the lower side of the molded nickel plate 5 to align the molded nickel plate 5 with the mold roller, and feeds the molded nickel plate 5 into the plate mounting module 23 to fit with the hot melt adhesive, and the plate mounting and the hot melt adhesive are attached to the mold roller to form the mold plate roller 11.
[0034] The hot melt adhesive traction module 21 includes a hot melt adhesive unwinding roller 211, a box 212, a telescopic screw rod 213 for adjusting the position of the box 212, an upper guide roller 214 and a lower guide roller 215 arranged in the box 212, wherein the upper guide roller 214 and the lower guide roller 215 are arranged on the unwinding side of the hot melt adhesive unwinding roller 211, and convey the hot melt adhesive to the plate mounting component 2 by rolling, contacting and pressing. The box 212 is connected to the movable end of the telescopic screw rod 213. During operation, the hot melt adhesive unwinding roller 211 first unwinds the hot melt adhesive sheet, and the upper guide roller 214 and the lower guide roller 215 clamp the hot melt adhesive sheet, and the hot melt adhesive is pulled to the plate mounting component 2 by their rolling, contacting and pressing action. When the hot melt adhesive sheet reaches the set length, the hot melt adhesive unwinding roller 211 stops unwinding, the upper guide roller 214 and the lower guide roller 215 clamp the hot melt adhesive sheet, and the cutting module 22 immediately cuts off the hot melt adhesive. Subsequently, the telescopic screw 213 drives the box 212 to retract backwards to complete the cutting and separation of the hot melt adhesive sheet. This automatic operation not only improves production efficiency, but also ensures the quality and consistency of the embossing plate roller 11 by accurately controlling the length of the hot melt adhesive.
[0035] The cutting module 22 includes a meter wheel 221 for obtaining the hot melt adhesive delivery length, a photoelectric switch 222 for detecting the hot melt adhesive, a glue cutter 223 and a guide wheel 224. The meter wheel 221 contacts the lower guide roller 215 to detect the rotation angle of the lower guide roller 215 to obtain the length of the hot melt adhesive sheet delivered. The photoelectric switch 222 is arranged at the glue cutter 223, and the glue cutter 223 is arranged opposite to the guide wheel 224. When the photoelectric switch 222 detects the hot melt adhesive sheet, the meter wheel 221 immediately starts counting and accurately measures the length of the hot melt adhesive. When the length recorded by the meter wheel 221 reaches the preset value (i.e., the circumference of the molding roller), the hot melt adhesive unwinding roller 211 stops unwinding. At this time, the hot melt adhesive is clamped by the upper guide roller 214 and the lower guide roller 215, and the glue cutter 223 immediately cuts off the hot melt adhesive to complete the cutting. Moreover, the guide wheel 224 can ensure the stability of the glue cutting knife 223 during the cutting process. After the cutting is completed, the glue cutting knife 223 is reset and waits for the next cutting action.
[0036] The plate mounting module 23 includes a preheating roller 231 for softening the hot melt adhesive and a release rubber roller 232. There is a gap between the preheating roller 231 and the release rubber roller 232 for the hot melt adhesive and the molded nickel plate 5 to pass through. The hot melt adhesive passes through the gap and is heated by the preheating roller 231 to soften it and have good viscosity. Through the synergistic effect of the preheating roller 231 and the release rubber roller 232, the hot melt adhesive sheet and the molded nickel plate 5 are not only tightly but also evenly attached, providing an ideal foundation for the subsequent formation of the molded plate roller 11. The surface of the release rubber roller 232 has a release layer, which avoids unnecessary adhesion of the hot melt adhesive during the transfer process, ensuring the smoothness of the attachment process and the quality of the molded plate roller 11.
[0037] Please also read Figure 3 There are two alignment modules 24, which are located at the edges of both ends of the molded nickel plate 5. A first detection cursor 241 is set on the molded nickel plate 5, a second detection cursor 242 is set on the release rubber roller 232, and a third detection cursor 243 is set on the molded roller. The two alignment modules 24 can move and adjust the position of the molded nickel plate 5 separately or simultaneously, so that the first detection cursor 241, the second detection cursor 242 and the third detection cursor 243 are aligned, and the molded nickel plate 5 will not be skewed (such as Figure 2 As shown on the right, before the molded nickel plate 5 is sent to the board mounting station, if Figure 2 In the state on the right side, the alignment module 24 on the left side can be moved forward slowly, or the alignment module 24 on the left side can be moved backward slowly at the same time, and the electric eye is used to detect whether the three cursors are in the same straight line. When the three cursors are in the same straight line, the calibration device stops moving and directly sends the molded nickel plate 5 between the preheating roller 231 and the release rubber roller 232 to make it stick with hot melt adhesive and fit with the molding roller.
[0038] Specifically, the first detection cursor 241, the second detection cursor 242 and the third detection cursor 243 are all cross marks, which can be printed or laser engraved on the molded nickel plate 5, the release rubber roller 232 and the molded roller, which can greatly improve the accuracy of detection. Among them, scales 244 are set at both ends of the alignment module 24. By inputting the length of the cross mark and the edge of the alignment module 24, the upper and lower distances of the molded nickel plate 5 from the edge of the alignment module 24 can be automatically adjusted to assist in adjusting the position of the molded nickel plate 5, and the cross mark can be accurately positioned (such as Figure 2 When the precise alignment is completed, the hot melt adhesive sheet and the molded nickel plate 5 arrive at the preheating roller 231 and the release rubber roller 232 at the same time, so that the two are attached.
[0039] Please continue reading Figure 1 and Figure 2The embossing assembly 1 includes a print unwinding roller 12, a coating roller 13, a embossing plate roller 11 and a print winding roller 14 which are arranged in sequence. A plurality of guide rollers 15 are arranged between the print unwinding roller 12 and the embossing plate roller 11, and between the embossing plate roller 11 and the print winding roller 14. An oil tank 16 and an anilox roller 17 in contact with the coating roller 13 are arranged on one side of the coating roller 13. A UV lamp 18 is arranged below the embossing plate roller 11. During the printing process, the print unwinding roller 12 and the print winding roller 14 are used to unwind and rewind the print, and the anilox roller 17 and the coating roller 13 apply ink to the embossing plate roller 11. The embossing plate roller 11 embosses the print to form a pattern or texture, and then the embossed print is cured by the UV lamp 18 to complete the entire embossing printing process. Moreover, the guide roller 15 is used to ensure the smooth transmission of the print during the embossing process, reduce tension fluctuations and material damage. Since the structure of the molded component 1 has been widely used in the prior art, it will not be elaborated here in detail.
[0040] Among them, the molding assembly 1 also includes a lifting member (the lifting member is not shown in the figure), and the molding plate roller 11 is arranged at the lifting end of the lifting member. The lifting member controls the molding plate roller to rise to the plate mounting assembly 2, and descends to the molding station after completing the plate mounting. Through the lifting member, the molding plate roller 11 can quickly rise to the plate mounting assembly 2 to perform the plate mounting operation, and can quickly descend to the molding station after completion, reducing the time for the molding plate roller 11 to transfer between different stations, thereby improving the overall production efficiency, and the automated lifting reduces the labor intensity of the operator, while reducing the risk of production accidents caused by improper manual operation.
[0041] The plate material monitoring component 3 includes a marking head 31, a first detection electric eye 32, a second detection electric eye 33, a third detection electric eye 34, a fourth detection electric eye 35, a first thickness measuring probe 36 and a second thickness measuring probe 37. The marking head 31 is arranged at the discharge end of the printed product unwinding roller 12 to set a mark on the printed product. When the first detection electric eye 32 detects the mark, the speed of the printed product unwinding roller 12 is reduced. When the second detection electric eye 33 detects the mark, the first thickness measuring probe 36 is triggered to detect the thickness of the printed product. The third detection electric eye 34, the fourth detection electric eye 35 The second thickness measuring probe 37 is arranged on the output side of the embossing plate roller 11. When the third detection electric eye 34 detects the mark, the speed of the printed product unwinding roller 12 is reduced. When the fourth detection electric eye 35 detects the mark, the second thickness measuring probe 37 is triggered to detect the thickness after embossing. Through the plate material monitoring component 3, the thickness of the printed product can be monitored in real time before and after embossing, problems can be discovered and adjusted in time, and material waste caused by uneven thickness can be reduced. In addition, through automated detection, the downtime in production is reduced, and the detection accuracy and production efficiency are improved compared with manual inspection.
[0042] The specific operation examples of the plate monitoring component 3 during detection are as follows:
[0043] The initial test of the film thickness before molding is recorded as t1, and the film thickness after molding is recorded as T1. The thickness measurement is carried out every 20 minutes, and the recorded data sequence is t1, T1, t2, T2, t3, T3...
[0044] The depth (d) of the photolithographic lines of the molded nickel plate 5 can be calculated as follows: d = Tt; as the number of tests increases, the changes in the depth of the photolithographic lines of the molded nickel plate 5 d1, d2, d3, etc. can be obtained.
[0045] Monitoring data table:
[0046] time Film thickness t Film thickness after molding T Depth of photoetched lines on molded nickel plate d 1 t1 T1 d1 2 t2 T2 d2 3 t3 T3 d3 4 t4 T4 d4 5 t5 T5 d5 6 t6 T6 d6 … … … …
[0047] During the molding process, varnish may cause the molded nickel plate 5 to be blocked, that is, the photolithographic lines become shallower, and the change in the depth of the photolithographic lines of the molded nickel plate 5 is particularly obvious in the printed product, resulting in a weakened laser effect of the printed product. The above analysis method is used to monitor the depth of the photolithographic lines of the molded nickel plate 5 in real time, and record the data when the product has problems, which can be used as a standard reference. When the depth of the photolithographic lines is less than the set value, an alarm is triggered to prompt the staff to clean the molded nickel plate 5 or replace the molded nickel plate 5, realizing the automation, dataization and standardization of the production process, improving production efficiency, product quality and equipment life. Subsequent products of the same model can be executed according to this standard data to realize the data management of plate use and scrapping.
[0048] Please also read Figure 4 and Figure 5The molding system with intelligent plate mounting and monitoring functions also includes a cleaning component 4, which includes a cleaning roller 41 for wiping the surface of the molding roller, a scraper 42 for removing the hot melt adhesive and the molded nickel plate 5 from the molding roller, and a winding roller 43 for rolling up the removed hot melt cavity and the molded nickel plate 5. The cleaning roller 41 is arranged on the upper side of the molding roller, the scraper 42 is arranged on one side of the cleaning roller 41, and the winding roller 43 is arranged on the left side of the scraper 42. In this embodiment, the plate mounting module 23 further includes a lifting bracket (the lifting bracket is not shown in the figure), and the preheating roller 231 is arranged at the lifting end of the lifting bracket. When the embossing plate roller 11 is lifted for cleaning, the preheating roller 231 is lifted and heats the embossing plate roller 11 to soften the hot melt adhesive. After the hot melt adhesive softens, the embossing plate roller 11 and the preheating roller stop rotating, and the preheating roller 231 is reset. The plate gap of the embossing plate roller 11 is aligned with the scraper 42, and the scraper 42 presses down and rotates the embossing plate roller 11, so that the scraper 42 rolls up the hot melt adhesive and the embossed nickel plate 5 together and attaches them to the roll roller 43 on the left side to collect waste. After complete separation, the cleaning roller 41 (the surface of the cleaning roller 41 has a cleaning cloth made of non-woven fabric) contacts and wipes the surface of the embossing roller to completely remove the residue, and the surface of the embossing roller is restored to a clean state to prepare for the next plate mounting operation.

[0051] S200, when the embossing plate roller is embossing, the plate material monitoring component detects the thickness of the printed product before and after embossing and the depth of the photolithographic lines of the embossed nickel plate.

[0056] S104, the calibration module aligns the molded nickel plate with the release rubber roller and the molded roller, and makes the molded nickel plate 5 located at the lower side of the hot melt adhesive sheet, and is synchronously fed into between the preheating roller and the release rubber roller with the hot melt adhesive sheet;
[0057] S105, the preheating roller and the release rubber roller flow and press to soften the hot melt adhesive sheet and stick the embossed nickel plate on the embossing roller to form an embossing plate roller.
