Description

Technical Field

[0001] This invention relates to the field of cold foil technology, and in particular to a cold foil and an apparatus for producing labels using the cold foil. Background Technology

[0002] Cold foil is a common printing material, often used in hot stamping processes in the printing industry. Cold foil does not require heating during the hot stamping process; the transfer of the metal foil layer is usually achieved through adhesives or pressure.

[0003] Common cold foil includes a coating layer, an aluminized layer, a transfer layer, and a PET substrate layer. In the cold foil printing process, printing is usually done first on a transparent label film. Then, UV cold foil adhesive is printed on the printed layer of the transparent label film. Next, the coating layer of the cold foil is bonded to the adhesive layer on the transparent label film. The transparent label film and the cold foil are then pressed together and the UV cold foil is cured. After the UV cold foil has cured, it tightly bonds the coating layer, the aluminized layer, and the transfer layer to the transparent label film. Finally, the PET substrate layer is removed from the laminated and cured label, leaving the transparent label film as a protective film for the label's design.

[0004] PET substrate becomes waste after the cold foil stamping process, resulting in low utilization efficiency of the cold foil. Summary of the Invention

[0005] The main objective of this invention is to provide a cold foil and an apparatus for producing labels using the cold foil, aiming to improve the problem of low utilization efficiency of cold foil.

[0006] To achieve the above objectives, the cold foil proposed in this invention comprises a coating layer, a metal plating layer, a transfer layer, and a PET substrate layer stacked sequentially.

[0007] A silicone oil layer is provided on the side of the PET substrate layer away from the transfer layer, and the silicone oil layer is used to bond to the transfer layer with adhesive.

[0008] The present invention also proposes a label production device using the aforementioned cold foil. The label production device includes a first unwinding mechanism, a printing mechanism, a UV cold foil printing mechanism, a second unwinding mechanism, a first laminating mechanism, a UV curing mechanism, a separating mechanism, an adhesive coating mechanism, and a second laminating mechanism arranged sequentially.

[0009] The first unwinding mechanism is used to unwind the transparent label film, the printing mechanism is used to print a pattern layer on the transparent label film, the UV cold foil printing mechanism is used to print a UV cold foil layer on the pattern layer, the second unwinding mechanism is used to unwind the cold foil, the first laminating mechanism is used to laminate the cold foil onto the transparent label film and make the coating adhere to the UV cold foil layer, and the UV curing mechanism is used to cure the UV cold foil.

[0010] The separation mechanism is used to separate the PET substrate layer from the transfer layer, the adhesive coating mechanism is used to apply adhesive to the silicone oil layer, and the second composite mechanism is used to composite the side of the silicone oil layer with adhesive onto the transfer layer.

[0011] In one embodiment, the label production equipment further includes a first reversing rack located between the separation mechanism and the coating mechanism. The first reversing rack is also used to flip the combined layer consisting of the silicone oil layer and the PET substrate layer.

[0012] In one embodiment, the printing mechanism includes a printing unit, which includes a printing group and a UV curing group, which are arranged sequentially.

[0013] In one embodiment, there are multiple printing units, which are arranged sequentially.

[0014] In one embodiment, the first composite mechanism includes a first upper pressure roller and a first lower pressure roller, which are used to press the cold foil onto the transparent label film.

[0015] In one embodiment, the label production equipment further includes a die-cutting mechanism, with the second laminating mechanism and the die-cutting mechanism arranged sequentially. The die-cutting mechanism is used to cut the transparent label film after the second lamination.

[0016] In one embodiment, a second reversing frame is provided between the second laminating mechanism and the die-cutting mechanism, the second reversing frame being used to flip the transparent label film after the second lamination.

[0017] In one embodiment, the label production equipment further includes a winding mechanism for winding up the transparent label film cut by the die-cutting mechanism.

[0018] In one embodiment, the label production equipment further includes a waste removal mechanism for winding up the waste transparent label film cut by the die-cutting mechanism.

[0019] The technical solution of this invention involves setting a silicone oil layer on a PET substrate layer. After cold foil stamping, adhesive is applied to the silicone oil layer. The silicone oil layer does not easily adhere to the adhesive. The silicone oil layer and the PET substrate layer together form a release film. When the silicone oil layer is bonded to the transfer layer, the adhesive on the silicone oil layer is transferred to the transfer layer. The silicone oil layer and the PET substrate layer can protect the adhesive on the transfer layer, ensuring the adhesion effect of the adhesive on the transfer layer. This achieves secondary utilization of the PET substrate, improves the utilization rate of the cold foil, and overall improves the problem of low utilization efficiency of the cold foil.

[0032] Common cold foil includes a coating layer, an aluminized layer, a transfer layer, and a PET substrate layer. In the cold foil printing process, printing is typically done first on a transparent label film. Then, UV cold foil adhesive is printed onto the printed layer of the transparent label film. Next, the coating layer of the cold foil is bonded to the adhesive layer on the transparent label film. The transparent label film and the cold foil are then pressed together and the UV cold foil is cured. After the UV cold foil has cured, it tightly bonds the coating, aluminized layer, and transfer layer to the transparent label film. Finally, the PET substrate layer is removed from the cured label, leaving the transparent label film as a protective film for the label's design. However, after cold foil printing, the PET substrate layer becomes waste, resulting in low utilization efficiency of the cold foil.

[0033] This invention proposes a cold foil stamping method.

[0034] Please see Figure 1 In one embodiment of the present invention, the cold foil includes a coating layer 11, a metal plating layer 12, a transfer layer 13 and a PET substrate layer 14 stacked in sequence; a silicone oil layer 15 is provided on the side of the PET substrate layer 14 away from the transfer layer 13, and the silicone oil layer 15 is used to be bonded to the transfer layer 13 by adhesive.

[0035] In an embodiment of the present invention, a silicone oil layer 15 is provided on the PET substrate layer 14. After cold foil stamping is completed, adhesive is applied to the silicone oil layer 15 to form an adhesive layer. The silicone oil layer 15 does not easily adhere to the adhesive. The combined layer formed by the silicone oil layer 15 and the PET substrate layer 14 achieves the effect of a release film. When the silicone oil layer 15 is bonded to the transfer layer 13, the adhesive layer on the silicone oil layer 15 is transferred to the transfer layer 13. The silicone oil layer 15 and the PET substrate layer 14 can protect the adhesive layer on the transfer layer 13, ensuring the bonding effect of the adhesive layer on the transfer layer 13. This realizes the secondary use of the PET substrate, improves the utilization rate of the cold foil, and improves the overall problem of low utilization efficiency of the cold foil.

[0036] The common metal plating layer 12 can be a copper plating layer or an aluminum plating layer. The metal plating layer 12 has a metallic luster. After cold foil stamping is completed, the metal plating layer 12 can improve the contrast effect of the printed pattern. The metal plating layer 12 is preferably an aluminum plating layer. The silicone oil layer 15 can also be other protective layers that play an anti-adhesion role.

[0037] PET substrate refers to polyethylene terephthalate, which is a thermoplastic polyester plastic.

[0038] Please see Figure 1 and Figure 2 The present invention also proposes a label production device that uses cold foil to produce labels. The label production device includes a first unwinding mechanism 201, a printing mechanism 202, a UV cold foil printing mechanism 203, a second unwinding mechanism 204, a first laminating mechanism 205, a UV curing mechanism 206, a separating mechanism, an adhesive coating mechanism 208, and a second laminating mechanism 209 arranged in sequence.

[0039] The first unwinding mechanism 201 is used to unwind the transparent label film, the printing mechanism 202 is used to print the pattern layer on the transparent label film, the UV cold foil printing mechanism 203 is used to print the UV cold foil layer on the pattern layer, the second unwinding mechanism 204 is used to unwind the cold foil, the first laminating mechanism 205 is used to laminate the cold foil onto the transparent label film and make the coating 11 press against the UV cold foil layer so that the coating 11 and the UV cold foil layer are tightly bonded, and the UV curing mechanism 206 is used to cure the UV cold foil.

[0040] The separation mechanism is used to separate the PET substrate layer 14 from the transfer layer 13, the adhesive coating mechanism 208 is used to coat the silicone oil layer 15 with adhesive, and the second composite mechanism 209 is used to composite the silicone oil layer 15 onto the transfer layer 13.

[0041] In an embodiment of the present invention, a first unwinding mechanism 201 continuously unwinds a transparent label film, and then a printing mechanism 202 prints a label pattern on the transparent label film. Next, UV cold foil is printed on the patterned side of the transparent label film. A second unwinding mechanism 204 continuously unwinds a cold foil, and a first composite mechanism 205 composites and bonds the unwound cold foil to the transparent label film. The UV cold foil adhesive bonds the coating 11 of the transparent label film and the cold foil. The UV cold foil adhesive is then cured by a UV curing mechanism 206, thus achieving cold foil printing on the transparent label film. After separating the PET substrate layer 14 from the transfer layer 13, adhesive is applied to the silicone oil layer 15, and the silicone oil layer 15 is composited onto the transfer layer 13. This transfers the adhesive from the silicone oil layer 15 to the transfer layer 13. The silicone oil layer 15 and the PET substrate layer 14 cooperate to form a release film, ensuring the adhesion of the adhesive on the transfer layer 13.

[0042] The transparent label film can be made of BOPP (biaxially oriented polypropylene film), PVC (polyvinyl chloride), PET (polyterephthalate), PVC shrink film, or PETG (polyethylene terephthalate) shrink film. The pattern printed on the transparent label film can be observed through it. In this embodiment, the transparent label film is preferably a transparent PETG shrink film. PETG shrink film has the characteristics of high transparency, high gloss, excellent printing color, and excellent printing performance. PETG shrink film has good transparency of the pattern, making it easy to view the printed pattern through the transparent label film after cold foil stamping. The transparent label film protects the pattern, reduces direct contact between the pattern and the outside, extends the shelf life of the pattern, and allows the label to maintain a good display effect for a longer period of time, enabling the label to be used for an extended period.

[0043] Please see Figure 1 and Figure 2 The printing mechanism 202 includes a printing unit 2021, which in turn includes a printing assembly 20211 and a UV curing assembly 20212, arranged sequentially. First, the printing assembly 20211 prints a pattern on the transparent label film. The UV curing assembly 20212 then cures the printed pattern on the transparent label film. After curing, the pattern is fixed, reducing deformation and ensuring the stability of the pattern on the transparent label film.

[0044] Multiple printing units 2021 are provided, and the multiple printing units 2021 are arranged sequentially. Through the multiple printing units 2021, corresponding patterns can be printed on the transparent label film in sequence according to the requirements; preferably, the multiple printing units 2021 can print patterns in layers on the transparent label film in sequence, which improves the scalability of the pattern printing on the transparent label film, and the multiple printing units 2021 ensure the printing effect of the pattern on the transparent label film.

[0045] The UV cold foil printing mechanism 203 can print UV cold foil on the transparent label film. In this embodiment of the invention, UV is an abbreviation for ultraviolet light. UV curing uses ultraviolet light to cure the adhesive and ink. The UV cold foil cures faster after being exposed to ultraviolet light. The UV curing mechanism 206 can specifically cure the UV cold foil. Before the UV cold foil is cured by the UV curing mechanism 206, it is difficult for the UV cold foil to cure naturally, which helps to ensure the bonding effect of the UV cold foil and ensures that the UV cold foil bonds the transparent label film and the coating 11 together. After the UV cold foil is cured by the UV curing mechanism 206, the UV cold foil can firmly bond the transparent label film and the coating 11 together, reducing the separation between the transparent label film and the coating 11.

[0046] Please see Figure 1 and Figure 2 The label production equipment further includes a first reversing frame 207, which is located between the separation mechanism and the coating mechanism 208. The first reversing frame 207 is also used to flip the composite layer composed of the silicone oil layer 15 and the PET substrate layer 14. Before passing through the first reversing frame 207, the silicone oil layer 15 is located on the side of the first reversing frame 207 away from the transfer layer. When the composite layer composed of the silicone oil layer 15 and the PET substrate layer 14 passes through the first reversing frame 207, the first reversing frame 207 flips the composite layer composed of the silicone oil layer 15 and the PET substrate layer 14, so that the silicone oil layer 15 is located on the side of the PET substrate layer 14 closer to the transfer layer 13. When the composite layer composed of the silicone oil layer 15 and the PET substrate layer 14 is laminated onto the transfer layer 13, it is convenient to directly bond the silicone oil layer 15 to the transfer layer 13.

[0047] The first composite mechanism 205 includes a first upper pressure roller 2051 and a first lower pressure roller 2052, both of which are rotatably mounted. The first upper pressure roller 2051 and the first lower pressure roller 2052 are used to press the cold foil onto the transparent label film. Both the transparent label film and the cold foil are located between the first upper pressure roller 2051 and the first lower pressure roller 2052. The first upper pressure roller 2051 and the second lower pressure roller 2052 continuously rotate as the transparent label film is conveyed, continuously pressing the transparent label film and the cold foil together. This reduces the gap between the transparent label film and the coating 11, and minimizes damage to the transparent label film, ensuring the adhesion effect of the UV cold foil adhesive between the transparent label film and the coating 11.

[0048] The first upper pressure roller 2051 and the first lower pressure roller 2052 can be replaced by an upper pressure plate and a lower pressure plate arranged in parallel, with the upper pressure plate and the lower pressure plate arranged close to or far from each other. When the upper pressure plate and the lower pressure plate are controlled to be close to each other, the transparent label film and the cold foil between the upper pressure plate and the lower pressure plate can be pressed together; when the upper pressure plate and the lower pressure plate are controlled to be far from each other, the transparent label film and the cold foil can be easily conveyed.

[0049] The adhesive applied by the adhesive applicator 208 can be a pressure-sensitive adhesive or a hot-melt pressure-sensitive adhesive.

[0050] Please see Figure 1 and Figure 2 When the adhesive applied by the adhesive coating mechanism 208 is a hot melt pressure-sensitive adhesive, the adhesive coating mechanism 208 includes an extrusion die, the feed port of the extrusion die is connected to an adhesive tank for storing adhesive, and the discharge port of the extrusion die is close to the silicone oil layer 15. With the help of the extrusion die, the adhesive can be squeezed onto the silicone oil layer 15.

[0051] Reference Figure 1 and Figure 4 When the adhesive applied by the coating mechanism 208 is a pressure-sensitive adhesive, the coating mechanism includes an adhesive coating unit 2081 and a support roller 2082. The support roller 2082 is rotatably arranged, with the PET substrate layer abutting against the support roller 2082. The silicone oil layer 15 is located on the side of the PET substrate layer 14 away from the support roller, and both the PET substrate layer and the silicone oil layer are located between the support roller 2082 and the adhesive coating unit 2081. Specifically, the adhesive coating unit 2081 is preferably a coating roller, with one side of the roller surface abutting against the pressure-sensitive adhesive and the other side of the roller surface abutting against the silicone oil layer. The coating roller rotates and can apply the pressure-sensitive adhesive onto the silicone oil layer.

[0052] A drying mechanism 214 is provided between the coating mechanism 208 and the second composite mechanism 209. With the help of the drying mechanism 214, the pressure-sensitive adhesive on the silicone oil layer 15 can be dried and cured.

[0053] The glue outlet of the glue coating mechanism 208 can also be set above the transparent label film, so that the extrusion die can directly squeeze the hot melt pressure-sensitive adhesive or pressure-sensitive adhesive onto the transfer layer 13, thereby directly coating the transfer layer with adhesive.

[0054] Pressure-sensitive adhesives are an important independent branch of the adhesives industry. Due to their dry tack and permanent tack, they can be repeatedly bonded, which helps to ensure the adhesion of labels.

[0055] Hot melt pressure-sensitive adhesive refers to a type of adhesive that is sensitive to pressure and can bond to the substrate with slight finger pressure without the need for solvents or other auxiliary means. Hot melt pressure-sensitive adhesive is a new type of pressure-sensitive adhesive with reusable properties, which allows the transfer layer to be bonded multiple times.

[0056] The second composite mechanism 209 includes a second upper pressure roller 2091 and a second lower pressure roller 2092. The second upper pressure roller 2091 is located above the second lower pressure roller 2092. The silicone oil layer 15 and the PET substrate layer 14 are both located between the extrusion die and the second upper pressure roller 2091. The silicone oil layer 15 is located on the side of the PET substrate layer 14 closer to the extrusion die. The extrusion die can directly apply hot melt pressure-sensitive adhesive or pressure-sensitive adhesive to the silicone oil layer. The silicone oil layer 15, the PET substrate layer 14, and the cold-stamped label are all located between the second upper pressure roller 2091 and the second lower pressure roller 2092. The second upper pressure roller 2091 and the second lower pressure roller 2092 cooperate to bond the silicone oil layer 15 to the transfer layer 13, so that the hot melt pressure-sensitive adhesive or pressure-sensitive adhesive is located between the silicone oil layer 15 and the transfer layer 13.

[0057] The label production equipment also includes a die-cutting mechanism 210. The second laminating mechanism 209 and the die-cutting mechanism 210 are arranged sequentially. The die-cutting mechanism 210 is used to cut the transparent label film after the second lamination. The die-cutting mechanism 210 includes a cutter, which can be a flat cutter or a curved cutter connected end to end to make the cutter ring-shaped. By improving the shape of the cutter of the die-cutting mechanism 210, the shape of the cutter's cross-section can be improved to change the shape of the label cut by the cutter.

[0058] The second composite mechanism 209, after laminating the silicone oil layer 15 onto the transfer layer 13, forms a label. The label includes a label layer and a PET substrate layer as a backing paper. The cutter is used to cut the label layer into label stickers of a specific shape, so that the label layer forms a label sticker layer and a waste layer. The number of label sticker layers depends on the structure of the cutter and the number of cuts. Both the label sticker layer and the waste layer are bonded to the PET substrate layer. By separating the waste layer from the PET substrate layer, the cut label sticker layer can be left on the PET substrate layer. When it is necessary to bond the label sticker layer, the label sticker layer to be bonded can be directly removed from the PET substrate layer and bonded to the area to be bonded.

[0059] The label production equipment also includes a second reversing frame 211, located between the second laminating mechanism 209 and the die-cutting mechanism 210. The second reversing frame 211 is used to flip the transparent label film after the second lamination. With the help of the second reversing frame 211, the transparent label film after the second laminating mechanism 209 can be flipped so that the transparent label film is above the printed pattern on the transparent label film. During die-cutting, the pattern can be observed through the transparent label film from above, facilitating observation of the die-cutting effect and allowing adjustments to the die-cutting system based on the actual die-cutting effect. This reduces damage to the pattern during die-cutting, thereby ensuring the integrity of the pattern.

[0060] The label production equipment also includes a winding mechanism 212, which is used to wind up the PET substrate layer with the label layer. By winding up the PET substrate layer with the label layer, the production of the labels is achieved. After the labels are wound together, it is convenient to store or transport the labels in a centralized manner.

[0061] The label production equipment also includes a waste discharge mechanism 213, which includes a winding drum. The winding drum can wind up the waste layer separated from the PET substrate layer, realizing the centralized collection of the waste layer cut by the die-cutting mechanism 210. This facilitates the centralized processing of the waste layer, reduces the scattering of the waste layer, and ensures the cleanliness of the production area.

[0062] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
