Description

[Technical Field]

[0001] This utility model relates to the field of printing, and in particular to a hot stamping UV transfer sticker printing device with replaceable substrate. [Background Technology]

[0002] Existing digital UV transfer labels have a wide range of applications, offering convenient small-batch customization, strong three-dimensional effect, and the ability to create cut-out labels without edge-tracing. They are widely used in packaging, decoration, and various cultural and creative sticker scenarios. There are two main methods for achieving digital hot stamping with this type of roll-to-roll digital printing equipment:

[0003] 1. Using a pre-coated self-adhesive release film on the substrate requires removing the adhesive from the areas not covered by the pattern layer after printing the ink layer design. This is necessary before hot stamping and subsequent processes of applying waste gold film and positioning film. This method is cumbersome, leaves adhesive residue, and hinders the rapid printing of high-quality hot stamping transfer designs. The industry standard for this method is "AB film adhesive removal hot stamping." Its advantage lies in the fact that the base adhesive is applied using a coating process, resulting in a high-performance adhesive that balances initial tack and long-term durability at various temperatures.

[0004] II. Direct-to-consumer adhesive application using inkjet printheads involves printing the adhesive layer, white ink layer, colored ink layer, and hot stamping varnish layer separately on the release paper. A hot stamping film is then applied, and after waste removal, a positioning film is applied. This process, commonly known in the industry as "direct-to-consumer adhesive application," has the advantage of being completed in a single operation with perfect detail. The disadvantage is that due to the ink limitations of inkjet printheads, the adhesives that can be printed exhibit insufficient initial tack at low temperatures. [Utility Model Content]

[0005] This invention combines the above two processes. First, it employs a "direct-spray hot stamping process" on the same machine for efficient and high-precision hot stamping. Then, it replaces the substrate with a release film pre-coated with self-adhesive. This overcomes the shortcomings of existing technologies, ensuring both the fineness of the hot stamping image and the excellent performance of the adhesive underneath. When the final application is applied to an item, the self-adhesive on the A film without the image is carried away by the positioning film, leaving no adhesive residue on the item. The machine completes all processes in one operation. Therefore, this invention provides a hot stamping UV-curable transfer printing device and its control method with replaceable substrates. This method is also known as "AB film hot stamping technology."

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

A pressure spring is disposed in the slide groove between the slider and the pressure block. A connecting rod is disposed on both sides of the machine base near the pattern transfer driven shaft, the positioning film coating driven shaft, or the gold film coating driven shaft.

[0017] The beneficial effects of this utility model are:

[0018] This invention uses a printing carriage assembly to sequentially print a self-adhesive layer, a white ink layer, a colored ink layer, and a hot stamping varnish layer on a first release paper. Then, a gold film coating assembly is used for hot stamping waste removal, achieving direct-jet printing of hot stamping patterns. Finally, a pattern transfer and positioning film coating assembly is used to transfer the hot stamping pattern and positioning film together to a second release paper. The entire process is continuously implemented on the equipment. This utility model integrates pattern printing, hot stamping, waste gold film removal, positioning film lamination, and A-film adhesive transfer processes, enabling high-quality hot stamping UV transfer stickers to be completed in one step. Furthermore, the pattern transfer and positioning film lamination assembly adopts a three-axis, two-layer lamination structure. First, the hot stamping pattern on the first release paper is transferred to the positioning film. Then, the positioning film and the hot stamping pattern are laminated onto the adhesive surface of the second release paper. This ensures excellent adhesion between the highly viscous adhesive on the second release paper and the relatively weak direct-jet adhesive, providing superior adhesive properties for later applications. Simultaneously, similar to ordinary AB film crystal labels, excess adhesive is carried away by the positioning film during customer transfer. The positioning film's own low-viscosity adhesive prevents damage to the hot stamping pattern, better protecting it and ensuring a more complete transfer to the product. This guarantees that the final UV hot stamping transfer sticker pattern can be perfectly transferred to various substrates. [Image Description]

[0026] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0027] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, descriptions involving "preferred," "second-best," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "preferred" or "second-best" may explicitly or implicitly include at least one of those features.

[0028] like Figure 1-6 As shown, a UV transfer sticker printing device with replaceable substrate includes an organic platform 1, a first release paper, a second release paper, and a positioning film. The transfer surface of the second release paper is pre-coated with self-adhesive. The platform 1 is sequentially equipped with a printing carriage assembly 2 that inkjet prints a self-adhesive layer, a white ink layer, a colored ink layer, and a hot stamping varnish layer on the printing surface of the first release paper; a gold film coating assembly 3 that presses gold film onto the hot stamping varnish layer of the release paper to form a hot stamping pattern layer; and a pattern transfer and positioning film coating assembly 4 that transfers the hot stamping pattern layer from the first release paper to the positioning film and covers the positioning film and the hot stamping pattern layer onto the transfer surface of the second release paper. Wherein, as... Figure 7 As shown, the printing carriage assembly 2 is equipped with a self-adhesive nozzle 24, a white ink nozzle 23, at least one color ink nozzle 22, at least one hot stamping varnish nozzle 21, and UV curing lamps 25 disposed on both sides of the printing carriage assembly 2; the machine base 1 is provided with a first release paper feeding shaft 11 at the input end of the printing carriage assembly 2 for outputting the first release paper; the machine base 1 is provided with a finished product receiving shaft 12 at the output end of the pattern transfer and positioning film coating assembly 4 for winding up the composite of the second release paper and the positioning film after coating.

[0029] A control method for a UV transfer printing apparatus using the aforementioned replaceable substrate includes:

[0030] S1. Preset printing carriage 2 prints self-adhesive patterns, white ink patterns, colored ink patterns and hot stamping patterns;

[0031] S2. After the first release paper enters the printing area of ​​the printing carriage assembly 2, the printing carriage assembly 2 sequentially inkjet prints a self-adhesive layer, a white ink layer, a colored ink layer, and a hot stamping varnish layer on the printing surface of the first release paper.

[0032] S3. After the first release paper enters the gold film coating component 3, the printing surface of the first release paper adheres to the gold film and is fed into the gold film coating component 3 to form a hot stamping pattern according to the printed hot stamping varnish.

[0033] S4. After the first release paper enters the pattern transfer and positioning film coating assembly 4, the printed surface of the first release paper is bonded to the positioning film and sent into the pattern transfer and positioning film coating assembly 4 to transfer the hot stamping pattern on the first release paper to the positioning film.

[0034] S5. The positioning film and the second release paper transfer surface are bonded together and fed into the pattern transfer and positioning film coating assembly 4 for a second time, so that the positioning film and hot stamping pattern are bonded to the second release paper transfer surface.

[0035] During the printing process, the printing carriage assembly 2 sequentially prints a self-adhesive layer, a white ink layer, a colored ink layer, and a hot stamping varnish layer on the first release paper to form a printed pattern. Then, the gold film coating assembly 3 applies hot stamping to the hot stamping varnish layer to form a hot stamping pattern. The direct injection printing method solves the problem of removing self-adhesive from the areas of the release paper not covered by the pattern layer. Subsequently, the pattern transfer and positioning film coating assembly 4 transfers the hot stamping pattern on the first release paper to the positioning film. Then, the pattern transfer and positioning film coating assembly 4 is used a second time to attach the positioning film and the hot stamping pattern to the transfer surface of the second release paper. The self-adhesive on the second release paper transfer surface has strong adhesion. After bonding with the printed self-adhesive, it enhances the adhesion of the UV transfer sticker. The adhesive outside the image adheres tightly to the positioning film. During customer transfer, excess adhesive is carried away by the positioning film, while the positioning film itself has lower adhesive strength, preventing damage to the hot stamping pattern. This better protects the hot stamping pattern and ensures its complete transfer to the product. This design integrates pattern printing, hot stamping, waste removal, and positioning film lamination into a single process, improving the production efficiency of hot stamping UV transfer stickers.

[0036] like Figure 4 As shown, the pattern transfer and positioning film coating assembly 4 includes a pattern transfer drive shaft 41, a pattern transfer driven shaft 42 that cooperates with the pattern transfer drive shaft 41 to transfer the hot stamping pattern layer on the first release paper to the positioning film, and a positioning film coating driven shaft 43 that cooperates with the pattern transfer drive shaft 41 to cover the positioning film and the hot stamping pattern layer onto the transfer surface of the second release paper. Figure 1-3As shown, a positioning film feeding shaft 8 is provided on the machine base 1 near the input end of the pattern transfer drive shaft 41 and the pattern transfer driven shaft 42; a first release paper receiving shaft 15 is provided on the machine base 1 near the output end of the pattern transfer drive shaft 41 and the pattern transfer driven shaft 42; a second release paper feeding shaft 9 is provided on the machine base 1 near the input end of the pattern transfer drive shaft 41 and the positioning film coating driven shaft 43, and a protective film is provided on the transfer surface of the second release paper; a protective film separation shaft 10 and a protective film receiving shaft 16 are provided on the machine base 1 near the input end of the pattern transfer drive shaft 41 and the positioning film coating driven shaft 43. When changing the substrate, the hot stamping pattern on the first release paper is attached to the positioning film output from the positioning film feeding shaft 8 and fed between the pattern transfer drive shaft 41 and the pattern transfer driven shaft 42 of the pattern transfer and positioning film coating assembly 4 to transfer the hot stamping pattern on the first release paper to the positioning film. The first release paper after the hot stamping pattern is transferred is then wound up by the first release paper take-up shaft 15. Subsequently, the positioning film and the hot stamping pattern are attached to the second release paper transfer surface output from the second release paper feeding shaft 9 and fed between the pattern transfer drive shaft 41 and the positioning film coating driven shaft 43 of the pattern transfer and positioning film coating assembly 4 to cover the second release paper transfer surface with the positioning film and the hot stamping pattern, thereby realizing the function of transferring the hot stamping pattern of the first release paper to the second release paper transfer surface. At the same time, the output second release paper separates the protective film on the second release paper transfer surface by the protective film separation shaft 10 and is wound up by the protective film take-up shaft 16.

[0037] like Figure 5 As shown, the gold film coating assembly 3 includes a gold film coating drive shaft 31 and a gold film coating driven shaft 32 that cooperates with the gold film coating drive shaft 31 to imprint gold film and the first release paper. Figure 1-3 As shown, a gold film feeding shaft 13 is provided on the machine base 1 near the input ends of the gold film coating drive shaft 31 and the gold film coating driven shaft 32. A gold film separating shaft 7 and a gold film taking-up shaft 14 are provided on the machine base 1 near the output ends of the gold film coating drive shaft 31 and the gold film coating driven shaft 32. During gold film hot stamping, the printing surface of the first release paper adheres to the gold film output from the gold film feeding shaft 13 and is fed into the gold film coating assembly 3 between the gold film coating drive shaft 31 and the gold film coating driven shaft 32, pressing the gold film onto the hot stamping varnish layer of the first release paper to form a hot stamping pattern layer. At the same time, the waste gold film after hot stamping is wound up by the gold film taking-up shaft 14.

[0038] like Figure 4-6As shown, pressure adjustment components 5 are respectively provided between the pattern transfer drive shaft 41 and the pattern transfer driven shaft 42, and between the pattern transfer drive shaft 41 and the positioning film coating driven shaft 43; pressure adjustment components 5 are also provided between the gold film coating drive shaft 31 and the gold film coating driven shaft 32. The above pressure adjustment components 5 have the same structure. The pressure between the driven shaft and the drive shaft can be adjusted by the pressure adjustment components 5, so that the gold film can be better hot stamped on the hot stamping varnish, so that the hot stamping pattern on the first release paper can be better transferred to the positioning film, and so that the positioning film and the hot stamping pattern can be better covered on the adhesive layer of the second release paper.

[0039] like Figure 5-6 As shown, the pressure regulating component 5 includes a slide groove 51 disposed on both sides of the machine base 1. A slider 52 is disposed in the slide groove 51. The two ends of the pattern transfer driven shaft 42, the positioning film coating driven shaft 43, or the gold film coating driven shaft 32 are respectively disposed in the two sliders 52. A pressure block 53 is disposed in the slide groove 51, with one end connected to the slider 52 and movable relative to it to drive the slider 52 to move. A pressure spring 54 is disposed in the slide groove 51 between the slider 52 and the pressure block 53. A connecting rod 55 is disposed on both sides of the machine base 1 near the pattern transfer driven shaft 42, the positioning film coating driven shaft 43, or the gold film coating driven shaft 32. An eccentric rod 56 is disposed on the outer side of both ends of the connecting rod 55. The eccentric rod 56 is disposed through the pressure block 53 so that the pressure block 53 is driven to move when the eccentric rod 56 is rotated. In use, rotating one side of the eccentric rod 56 causes the eccentric rods 56 on both sides to rotate synchronously via the connecting rod 55. At this time, the eccentric rods 56 on both sides drive the pressure blocks 53 on both sides to move, which in turn drives the slider 52 to move in the slide groove 51, thereby driving the driven shaft to move up and down.

[0040] like Figure 5-6 As shown, a pressure nozzle 57 is provided between the pressure block 53 and the pressure spring 54. A bolt 58, with its lower end connected to the pressure nozzle 57, is provided on the pressure block 53 for adjusting the pressure of the pressure spring 54. By rotating the bolt 58, the pressure nozzle 57 is moved, adjusting the pressure of the pressure spring 54 on the pressure block 53, thereby further adjusting the pressure between the driven shaft and the driving shaft. The inner sides of the slide groove 51 are provided with steps 59, and the slider 52 has protrusions 510 on both sides that mate with the steps 59, used to limit the maximum stroke between the driven shaft and the driving shaft.

[0041] like Figure 4-6 As shown, a heating tube 61 is provided inside the positioning film coating driven shaft 43, and heating insulation plates 62 are provided on both sides of the slider 52 to fix the heating tube 61 on the slider 52, thereby improving the gold foil hot stamping effect; a heating tube 61 is provided inside the gold foil coating driven shaft 32, and heating insulation plates 62 are provided on both sides of the slider 52 to fix the heating tube 61 on the slider 52, thereby improving the coating effect of the positioning film and the second release paper.
