[0032] Common cold stamping foils include coating, aluminized layer, transfer layer and PET substrate layer. In the process of cold stamping printing, it is often printed on the transparent label film first, and then UV cold stamping glue is printed on the printing layer of the transparent label film, and then the coating of the cold stamping foil is attached to the glue layer on the transparent label film, and then the transparent label film and the cold stamping foil are pressed and laminated, and the laminated UV cold stamping glue is cured. After the UV cold stamping glue is cured, the UV cold stamping glue tightly bonds the coating, aluminized layer and transfer layer to the transparent label film, and finally the PET substrate layer is removed from the laminated and cured label, so that the transparent label film is used as a protective film for the label pattern; after the cold stamping foil is completed, the PET substrate layer becomes waste, and the utilization efficiency of the cold stamping foil is low.

[0033] The invention provides a cold stamping foil.

[0034] See also Figure 1 In one embodiment of the present invention, the cold stamping 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 a 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 glue.

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

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

[0038] See also Figure 1 and Figure 2 The present invention also provides a device for producing labels, using cold foil to produce labels, the device for producing labels comprises a first unwinding mechanism 201, a printing mechanism 202, a printing UV cold foil glue mechanism 203, a second unwinding mechanism 204, a first compounding mechanism 205, a UV curing mechanism 206, a separation mechanism, a gluing mechanism 208 and a second compounding mechanism 209 which are arranged in sequence;

[0039] The first unwinding mechanism 201 is used for unwinding the transparent label film, the printing mechanism 202 is used for printing the pattern layer on the transparent label film, the printing UV cold stamping glue mechanism 203 is used for printing the UV cold stamping glue layer on the pattern layer, the second unwinding mechanism 204 is used for unwinding the cold stamping foil, the first compounding mechanism 205 is used for compounding the cold stamping foil on the transparent label film, and making the coating 11 against the UV cold stamping glue layer, so that the coating 11 and the UV cold stamping glue layer are closely attached, and the UV curing mechanism 206 is used for curing the UV cold stamping glue;

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

[0041] In the embodiment of the present invention, the transparent label film is continuously unwound by the first unwinding mechanism 201, and then the label pattern is printed on the transparent label film by means of the printing mechanism 202, and then the UV cold stamping glue is printed on the side of the transparent label film with the pattern; the second unwinding mechanism 204 continuously unwinds the cold stamping foil, and the unwound cold stamping foil is compositely bonded to the transparent label film by the first composite mechanism 205, and the UV cold stamping glue can bond the transparent label film and the coating 11 of the cold stamping foil, and then the UV cold stamping glue is cured by means of the UV curing mechanism 206, so that the cold stamping printing on the transparent label film is realized; after the PET substrate layer 14 is separated from the transfer layer 13, the silicone oil layer 15 is coated with glue and composited with the silicone oil layer 15 on the transfer layer 13, so that the glue on the silicone oil layer 15 can be transferred to the transfer layer 13, and the silicone oil layer 15 cooperates with the PET substrate layer 14 to form a release film, thereby ensuring the bonding effect of the glue on the transfer layer 13.

[0042] The material of the transparent label film can be BOPP (biaxially oriented polypropylene film), PVC (polyvinyl chloride), PET (polyethylene terephthalate plastic), PVC shrink film and PETG (polyethylene terephthalate) shrink film. The pattern printed on the transparent label film can be observed through the transparent label film. In this embodiment, the transparent label film is preferably a transparent PETG shrink film. The PETG shrink film has the characteristics of high transparency, high gloss, excellent printing color, high transparency and excellent printing performance. The PETG shrink film has a good penetration effect on the pattern. After the cold stamping is completed, the printed pattern can be conveniently viewed through the transparent label film. The transparent label film can protect the pattern, reduce the direct contact between the pattern and the external connection, and extend the shelf life of the pattern, so that the label maintains a good display effect for a long time, and the label can be used for a long time.

[0043] See also Figure 1 and Figure 2 The printing mechanism 202 includes a printing unit 2021, and the printing unit 2021 includes a printing group 20211 and a UV curing group 20212. The printing group 20211 and the UV curing group 20212 are arranged in sequence. First, the pattern is printed on the transparent label film by the printing group 20211, and the UV curing group 20212 can cure the pattern printed on the transparent label film. After the pattern is cured, the pattern is fixed, the deformation of the pattern is reduced, and the stability of the pattern on the transparent label film is guaranteed.

[0044] There are multiple printing units 2021, and the multiple printing units 2021 are arranged in sequence. Through the multiple printing units 2021, corresponding patterns can be printed on the transparent label film in sequence according to needs; preferably, the multiple printing units 2021 can print patterns in layers on the transparent label film in sequence, which improves the scalability of 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 printing UV cold-iron glue mechanism 203 can print UV cold-iron glue on the transparent label film. UV in the embodiment of the present invention is the abbreviation of ultraviolet rays. UV curing is to use ultraviolet rays to cure glue and ink. UV cold-iron glue is cured faster after being irradiated by ultraviolet rays. The UV curing mechanism 206 can realize the curing of UV cold-iron glue in a targeted manner. Before the UV curing mechanism 206 cures the UV cold-iron glue, the UV cold-iron glue is difficult to cure naturally, which is conducive to ensuring the bonding effect of the UV cold-iron glue and can ensure that the UV cold-iron glue bonds the transparent label film to the coating 11. After the UV curing mechanism 206 cures the UV cold-iron glue, the UV cold-iron glue can firmly bond the transparent label film to the coating 11, reducing the separation between the transparent label film and the coating 11.

[0046] See also Figure 1 and Figure 2 The equipment for producing labels further includes a first reverse rack 207, which is located between the separation mechanism and the glue coating mechanism 208. The first reverse rack 207 is also used to flip the combined layer composed of the silicone oil layer 15 and the PET substrate layer 14. Before the combined layer composed of the silicone oil layer 15 and the PET substrate layer 14 passes through the first reverse rack 207, the silicone oil layer 15 is located on the side of the first reverse rack 207 away from the transfer layer; when the combined layer composed of the silicone oil layer 15 and the PET substrate layer 14 passes through the first reverse rack 207, the combined layer composed of the silicone oil layer 15 and the PET substrate layer 14 is flipped by means of the first reverse rack 207, so that the silicone oil layer 15 is located on the side of the PET substrate layer 14 close to the transfer layer 13, and when the combined layer composed of the silicone oil layer 15 and the PET substrate layer 14 is composited on 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 pressing roller 2051 and a first lower pressing roller 2052. The first upper pressing roller 2051 and the first lower pressing roller 2052 are both rotatably arranged. The first upper pressing roller 2051 and the first lower pressing roller 2052 are used to press the cold foil on the transparent label film. The transparent label film and the cold foil are both located between the first upper pressing roller 2051 and the first lower pressing roller 2052. The first upper pressing roller 2051 and the second lower pressing roller 2092 continuously rotate with the transportation of the transparent label film, and can continuously press the transparent label film and the cold foil together, thereby reducing the gap between the transparent label film and the coating 11, and not easily causing damage to the transparent label film, thereby ensuring the bonding effect of the UV cold foil glue on the transparent label film and the coating 11.

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

[0049] The glue applied by the glue coating mechanism 208 may be a pressure-sensitive adhesive or a hot-melt pressure-sensitive adhesive.

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

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

[0052] A drying mechanism 214 is provided between the glue coating mechanism 208 and the second composite mechanism 209 . With the aid 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 arranged above the transparent label film, so that the extrusion die head directly squeezes the hot melt pressure sensitive adhesive or the pressure sensitive adhesive onto the transfer layer 13, thereby directly coating the transfer layer with glue.

[0054] Pressure-sensitive adhesive is an important independent branch in the field of adhesives. Due to its dry and permanent adhesive properties, it can be repeatedly bonded, which is convenient for ensuring the bonding effect of labels.

[0055] Hot melt pressure sensitive adhesive refers to a type of adhesive that is sensitive to pressure and can be bonded to the adherend with just a little pressure from the finger, without the need for solvents or other auxiliary means. Hot melt pressure sensitive adhesive is a new type of pressure sensitive adhesive that is reusable, allowing the transfer layer to be bonded multiple times.

[0056] The second composite mechanism 209 includes a second upper pressing roller 2091 and a second lower pressing roller 2092. The second upper pressing roller 2091 is located on the upper side of the second lower pressing roller 2092. The silicone oil layer 15 and the PET substrate layer 14 are both located between the extrusion die and the second upper pressing roller 2091. The silicone oil layer 15 is located on the side of the PET substrate layer 14 close 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 label after cold stamping are all located between the second upper pressing roller 2091 and the second lower pressing roller 2092. The second upper pressing roller 2091 and the second lower pressing 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 equipment for producing labels also includes a die-cutting mechanism 210. The second compounding mechanism 209 and the die-cutting mechanism 210 are sequentially arranged. The die-cutting mechanism 210 is used to cut the transparent label film after the second compounding. The die-cutting mechanism 210 includes a cutter. The cutter can be a flat cutter, or the cutter can be bent and connected end to end so that the cutter is annular. By improving the shape of the cutter of the die-cutting mechanism 210, the shape of the cross section of the cutter can be improved to change the shape of the label cut by the cutter.

[0058] The second composite mechanism 209 composites the silicone oil layer 15 on the transfer layer 13 to form a label; the label includes a label layer and a PET substrate layer as a backing paper, the cutter is used to cut label stickers of a specific shape from the label layer, so that the label layer forms a label layer and a waste layer, the number of label layers depends on the structure of the cutter and the number of cutting times of the cutter, the label layer and the waste layer are both bonded to the PET substrate layer, and by separating the waste layer from the PET substrate layer, the cut label layer can be retained on the PET substrate layer, and when the label layer needs to be bonded, the label layer to be bonded can be directly removed from the PET substrate layer, and the label layer to be bonded can be bonded to the area to be bonded.

[0059] The equipment for producing labels also includes a second reverse rack 211, which is located between the second composite mechanism 209 and the die-cutting mechanism 210. The second reverse rack 211 is used to flip the transparent label film after the second composite. With the help of the second reverse rack 211, the transparent label film after the second composite mechanism 209 can be flipped so that the transparent label film is located on the upper side of the printed pattern on the transparent label film. When the transparent label film is die-cut, the pattern can be observed through the transparent label film from the upper side, which is convenient for observing the die-cutting effect, and the die-cutting system can be adjusted according to the actual effect of the die-cutting to reduce the damage to the pattern during the die-cutting, thereby ensuring the integrity of the pattern.

[0060] The equipment for producing labels also includes a winding mechanism 212, which is used to wind up the PET substrate layer composited with the label layer. The winding mechanism 212 winds up the PET substrate layer bonded with the label layer, thereby realizing the winding of the labels after production. After the labels are rolled up together, it is convenient to centrally store or transport the labels.

[0061] The equipment for producing labels also includes a waste discharge mechanism 213, which includes a winding drum. The winding drum can roll up the waste layer separated from the PET substrate layer, thereby realizing the centralized collection of the waste layer cut by the die-cutting mechanism 210, facilitating the centralized processing of the waste layer, reducing the scattering of the waste layer, and ensuring the cleanliness of the production area.
