Description

Technical Field

[0001] This invention relates to the field of cold foil transfer technology, and more particularly to a cold foil transfer device and a cold foil transfer method. Background Technology

[0002] Cold foil transfer equipment uses ultraviolet light to irradiate UV adhesive, allowing the object to be transferred to cure onto the transfer carrier through the UV adhesive. Before curing, UV adhesive is typically applied to the transfer carrier to achieve cold foil transfer curing. Compared to curing methods that require heat, such as hot melt adhesives, cold foil transfer equipment does not require heating, has less impact on product performance, and the process is safer and more convenient.

[0003] During cold foil stamping, the transfer carrier and the object to be transferred need to be in full contact and adhere to each other to effectively cure the object onto the transfer carrier. Current cold foil stamping equipment typically achieves this adhesion by applying pressure from above or both sides. This method results in poor adhesion and unsatisfactory curing results. Summary of the Invention

[0004] The purpose of this invention is to provide a cold foil transfer device and a cold foil transfer method, which achieves good adhesion between the transfer carrier and the transfer object and ideal cold foil curing effect.

[0005] This invention discloses a cold foil transfer printing device, including a frame, a conveyor track, a feeding mechanism, an ultraviolet (UV) light irradiation mechanism, and an upper lifting mechanism. The conveyor track is mounted on the frame, and the feeding mechanism is located on one side of the frame. The UV light irradiation mechanism is mounted on the frame and is used to solidify the transfer object onto the transfer carrier. The upper lifting mechanism is installed below the conveyor track and corresponds to the UV light irradiation mechanism. The upper lifting mechanism is used to rise from below the conveyor track and lift the transfer carrier during UV irradiation, so that the transfer carrier adheres to the transfer object.

[0006] Optionally, the ultraviolet light irradiation mechanism includes a pre-curing light irradiation mechanism, and an upper mechanism is provided corresponding to the pre-curing light irradiation mechanism; the pre-curing light irradiation mechanism is used to pre-cur the transfer object.

[0007] Optionally, the ultraviolet light irradiation mechanism also includes a re-curing light irradiation mechanism; in the transport direction of the transport track, the re-curing light irradiation mechanism is located after the initial curing light irradiation mechanism; the re-curing light irradiation mechanism is used to finally cure the transfer object.

[0008] Optionally, the upper lifting mechanism includes a mounting frame, an upper lifting drive, and an upper lifting component; the upper lifting drive is mounted on the mounting frame, the upper lifting component is positioned above the mounting frame, and the upper lifting drive is connected to the upper lifting component; the upper lifting drive drives the upper lifting component to rise or fall; the upper lifting component is used to rise from below the conveyor belt frame of the cold foil transfer equipment and lift the cold foil transfer carrier.

[0009] Optionally, the lifting mechanism further includes a first drive assembly; the mounting frame is mounted on the drive mechanism; when the lifting drive unit drives the lifting component to lift, the drive mechanism drives the mounting frame to move, thereby changing the lifting position of the lifting component.

[0010] Optionally, the first drive assembly includes a first drive member, a slide rail, and a mounting base; the mounting base is slidably mounted on the slide rail, the first drive member is connected to the mounting base, and the mounting frame is mounted on the mounting base; the first drive member drives the mounting frame to reciprocate, so as to complete the change and reset of the lifting position when the upper lifting member is lifted.

[0011] Optionally, both the initial curing illumination mechanism and the re-curing illumination mechanism include a first mounting shell, an ultraviolet lamp, and a shield; a mounting cavity is formed inside the first mounting shell, and the mounting cavity has a light outlet for ultraviolet light to be emitted; the ultraviolet lamp is installed in the mounting cavity; the shield is rotatably installed in the mounting cavity; by rotating, the shield can block or open the light outlet to adjust the irradiation range of the ultraviolet light.

[0012] Optionally, the shielding cover includes two first shielding sub-shiels; the two first shielding sub-shiels are arranged opposite each other; by rotating, the two first shielding sub-shiels can be aligned with each other to block the light outlet or separated from each other to open the light outlet.

[0013] Optionally, the portion of the transfer carrier at the entrance of the ultraviolet irradiation mechanism is tilted downwards at an angle of 40–70° relative to the horizontal plane.

[0014] The present invention also discloses a cold foil transfer method, applied to the cold foil transfer equipment as described above, including the following steps;

[0015] The object to be transferred is fed onto the feeding mechanism and passes through the ultraviolet light irradiation mechanism on the transport track; the transfer carrier is fed onto the transport track and passes through the ultraviolet light irradiation mechanism.

[0016] The upper lifting mechanism rises from below the transfer track and lifts the transfer carrier so that the transfer carrier fits into the transfer object, completing the cold foil transfer curing.

[0017] The cold foil transfer equipment of this invention achieves cold foil transfer by setting up an ultraviolet light irradiation mechanism and an upward lifting mechanism. The key point is that when the ultraviolet light irradiation mechanism irradiates ultraviolet light, the upward lifting mechanism rises from below the transmission track and lifts the transfer carrier. While irradiating with ultraviolet light, it applies additional upward pressure to the transfer carrier, so that the transfer object and the transfer carrier are subjected to both compression and upward lifting forces while curing, achieving simultaneous upward compression and curing. At the same time, the upward lifting mechanism lifts the transfer carrier, further increasing the tension of the transfer carrier, so that the transfer carrier and the transfer object can fit more closely together, improving the cold foil curing effect. This is different from ordinary roller pressing methods or methods that separate ultraviolet light irradiation and roller pressing. Attached Figure Description

Detailed Implementation

[0031] It should be understood that the terminology, specific structural and functional details used herein are merely for describing particular embodiments and are representative. However, the invention can be implemented in many alternative forms and should not be construed as being limited to the embodiments set forth herein.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and optional embodiments.

[0033] like Figure 1 and Figure 2 As shown in the figure, as an embodiment of the present invention, a cold foil transfer device is disclosed, including a frame, a conveyor track 1, a feeding mechanism 2, an ultraviolet light irradiation mechanism 3, and an upper lifting mechanism 4; the conveyor track 1 is installed on the frame, and the feeding mechanism 2 is disposed on one side of the frame; the ultraviolet light irradiation mechanism 3 is installed on the frame and is used to solidify the transfer object 6 onto the transfer carrier 5; the upper lifting mechanism 4 is installed below the conveyor track 1 and corresponds to the ultraviolet light irradiation mechanism 3; the upper lifting mechanism 4 is used to rise from below the conveyor track 1 and lift the transfer carrier 5 during ultraviolet light irradiation so that the transfer carrier 5 adheres to the transfer object 6.

[0034] The cold foil stamping transfer equipment of this invention achieves cold foil stamping transfer by setting up an ultraviolet light irradiation mechanism 3 and an upward lifting mechanism 4. The key point is that when the ultraviolet light irradiation mechanism 3 irradiates the transfer carrier 5, the upward lifting mechanism 4 rises from below the transport track 1 and lifts the transfer carrier 5. While irradiating with ultraviolet light, it applies further upward pressure to the transfer carrier 5, allowing the transfer object 6 and the transfer carrier 5 to experience both compression and upward lifting forces simultaneously during curing, achieving synchronous upward compression and curing. At the same time, the upward lifting mechanism 4 lifts the transfer carrier 5, further increasing the tension of the transfer carrier 5, allowing the transfer carrier 5 and the transfer object 6 to adhere more closely, improving the cold foil stamping curing effect. This differs from ordinary roller pressing methods or methods that separate ultraviolet light irradiation and roller pressing. Specifically, the transfer object 6 can be a photopolymer, etc.

[0035] Optionally, the ultraviolet light irradiation mechanism 3 includes a pre-curing light irradiation mechanism 31, and an upper lifting mechanism 4 correspondingly arranged to the pre-curing light irradiation mechanism 31; the pre-curing light irradiation mechanism 31 is used for preliminary curing of the transfer object 6. In this scheme, during the curing process, the transfer object 6 is first pre-cured by the pre-curing light irradiation mechanism 31 to improve the effect and efficiency of cold foil transfer curing. Specifically, the upper lifting mechanism 4 is arranged corresponding to the pre-curing light irradiation mechanism 31. During preliminary curing, the upper lifting mechanism 4 rises from below the transfer track 1 and lifts the transfer carrier 5, so that the transfer object 6 and the transfer carrier 5 have both squeezing and lifting forces while curing, so that the transfer carrier 5 and the transfer object 6 achieve synchronous upper squeezing and curing at the preliminary curing position, and the upper lifting mechanism 4 lifts the transfer carrier 5 to increase the tension of the transfer carrier 5.

[0036] Optionally, the ultraviolet light irradiation mechanism 3 also includes a re-curing light irradiation mechanism 32; in the transmission direction of the transmission track 1, the re-curing light irradiation mechanism 32 is positioned after the initial curing light irradiation mechanism 31; the re-curing light irradiation mechanism 32 is used for the final curing of the transfer object 6. In this scheme, after initial curing, the transfer object 6 is finally cured by the re-curing light irradiation mechanism 32, achieving ideal cold foil transfer curing through two curing processes. Importantly, because the transfer carrier 5 and the transfer object 6 are tightly adhered by the upper lifting mechanism 4 during the initial curing, the initial cold foil transfer curing effect in the initial curing process is better, laying a solid "foundation." The initial curing and re-curing work together, so when the final curing is performed by the re-curing light irradiation mechanism 32, the desired ideal effect can be easily achieved.

[0037] Optionally, such as Figure 3 and Figure 4As shown, the upper lifting mechanism 4 includes a mounting frame 41, an upper lifting drive 42, and an upper lifting member 43. The upper lifting drive 42 is mounted on the mounting frame 41, and the upper lifting member 43 is positioned above the mounting frame 41, with the upper lifting drive 42 connected to the upper lifting member 43. The upper lifting drive 42 drives the upper lifting member 43 to rise or fall. The upper lifting member 43 is used to rise from below the conveyor belt frame of the cold foil transfer equipment and lift the cold foil transfer carrier 5. In this solution, the upper lifting mechanism 4, by setting the upper lifting drive 42 and the upper lifting member 43, allows the upper lifting member 43 to rise from below the transport track 1 and lift the cold foil transfer carrier 5 under the drive of the upper lifting drive 42, providing further upward pressure to the transfer carrier 5. This combines the squeezing and upward force on the transfer object 6 and the transfer carrier 5, making the transfer carrier 5 fit more tightly with the transfer object 6, ensuring sufficient adhesion between the transfer object 6 and the transfer carrier 5, and improving the cold foil curing effect.

[0038] Specifically, the upper lifting drive component 42 can be a cylinder. Optionally, the upper lifting mechanism 4 also includes a lifting column 44, which is vertically and flexibly inserted into the mounting frame 41, with one end of the lifting column 44 connected to the upper lifting component 43. By providing the lifting column 44 and connecting it to the upper lifting component 43, the stability of the upper lifting component 43 during lifting is improved. Optionally, there are two lifting columns 44, and the two lifting columns 44 are located on both sides of the upper lifting drive component 42, which can further improve the stability of the upper lifting component 43 during lifting.

[0039] Optionally, an outer sleeve 45 is installed on the mounting frame 41, extending axially through the frame. The lifting column 44 is vertically inserted into the outer sleeve 45, improving the installation stability of the lifting column 44. Specifically, the inner wall surface of the axial through hole of the outer sleeve 45 can be made smooth, and lubricant can also be injected between the axial through hole of the outer sleeve 45 and the lifting column 44 to improve the smoothness of the lifting column 44's movement.

[0040] Optionally, the upper ejector 43 includes a connecting seat 431 and a top pressure roller 432. The connecting seat 431 is connected to the upper ejector drive 42, and the top pressure roller 432 is mounted on the connecting seat 431 for easy production assembly. The upper ejector drive 42 is connected to the connecting seat 431, and the connection is convenient and secure. The top pressure roller 432 presses the transfer carrier 5, resulting in a good pressing effect and minimizing damage to the transfer carrier 5. Specifically, the top pressure roller 432 is rotatably mounted on the connecting seat 431 and can rotate relative to the transfer carrier 5, facilitating the transfer and movement of the transfer carrier 5 and also facilitating the movement of the upper ejector mechanism 4.

[0041] Optionally, the upper lifting mechanism 4 further includes a first driving component 46; the mounting frame 41 is mounted on the first driving component 46; when the upper lifting drive component 42 drives the upper lifting component 43 to lift, the first driving component 46 drives the mounting frame 41 to move, thereby changing the lifting position of the upper lifting component 43. In this solution, by setting the first driving component 46, when the upper lifting drive component 42 drives the upper lifting component 43 to lift the transfer carrier 5, the first driving component 46 drives the mounting frame 41 to move, thereby changing the lifting position of the upper lifting component 43. This can expand the pressing area of ​​the upper lifting component 43, improving the curing effect and efficiency. Specifically, the first driving component 46 can drive the mounting frame 41 to reciprocate.

[0042] Optionally, the first drive assembly 46 includes a first drive member 461, a slide rail 462, and a first mounting base 463. The first mounting base 463 is slidably mounted on the slide rail 462, the first drive member 461 is connected to the first mounting base 463, and the mounting frame 41 is mounted on the first mounting base 463. The first mounting base 463, mounted on the slide rail 462, provides stable sliding; the mounting frame 41, mounted on the first mounting base 463, facilitates assembly. The first drive member 461 drives the mounting frame 41 to reciprocate, thereby changing and resetting the lifting position of the upper lifting member 43 when it is lifted. Specifically, the first drive member 461 can be a cylinder, etc.

[0043] Optionally, such as Figures 5 to 7 As shown, both the initial curing illumination mechanism 31 and the re-curing illumination mechanism 32 include a first mounting shell 311, an ultraviolet lamp 312, and a shield 313. A mounting cavity 3111 is formed inside the first mounting shell 311, and the mounting cavity 3111 has a light outlet 3112 for ultraviolet light to be emitted. The ultraviolet lamp 312 is installed in the mounting cavity 3111. The shield 313 is rotatably installed in the mounting cavity 3111. By rotating, the shield 313 can block or open the light outlet 3112 to adjust the irradiation range of the ultraviolet light. In this design, the initial curing light irradiation mechanism 31 and the re-curing light irradiation mechanism 32 are equipped with a shield 313, which is rotatably installed in the mounting cavity 3111. By rotating, the shield 313 can block or open the light outlet 3112, thereby realizing the adjustment of the ultraviolet light irradiation range and the opening and closing of the ultraviolet lamp. The opening and closing and the irradiation range control are convenient.

[0044] Optionally, such as Figures 7 to 9As shown, the shielding cover 313 includes two first shielding sub-covers 3131; the two first shielding sub-covers 3131 are arranged opposite to each other; by rotation, the two first shielding sub-covers 3131 can either engage with each other to shield the light outlet 3112 or disengage to open the light outlet 3112. In this solution, the two first shielding sub-covers 3131 are provided. By engaging or disengaging the two first shielding sub-covers 3131, the light outlet 3112 can be shielded or opened quickly and efficiently. Furthermore, when the two first shielding sub-covers 3131 are disengaged, the emitted light is the stronger ultraviolet light from the central region of the ultraviolet lamp 312. Compared to opening from one side, the ultraviolet light is utilized more fully, resulting in a better irradiation effect. Specifically, the light outlet 3112 of the mounting cavity 3111 can be located at the bottom. In this case, the transfer curing position is below the initial curing light irradiation mechanism 31 and the re-curing light irradiation mechanism 32. The UV adhesive on the transfer carrier 5 is cured by irradiation with ultraviolet light 312, thus completing the transfer. Specifically, the two first shielding sub-masks 3131 can be arc-shaped.

[0045] Optionally, such as Figure 7 and Figure 8 As shown, the initial curing illumination mechanism 31 and the re-curing illumination mechanism 32 also include a second driving component 314. The second driving component 314 is connected to the two first blocking sub-covers 3131 for transmission, so as to drive the two first blocking sub-covers 3131 to engage with each other to block the light outlet 3112 or to separate and open the light outlet 3112. In this solution, the two first blocking sub-covers 3131 are driven to engage and disengage by the second driving component 314, which is convenient to use. Specifically, the second driving component 314 can be manual or electric. The second driving component 314 can drive the two first blocking sub-covers 3131 to move simultaneously, resulting in high motion consistency and high operating efficiency.

[0046] Optionally, such as Figure 9 and Figure 10As shown, the second drive assembly 314 includes a second drive member 3141 and two sets of linkage assemblies 3142. Each linkage assembly 3142 includes a first link 31421 and a second link 31422. The first link 31421 is fixedly connected to the second drive member 3141, and the second link 31422 is movably connected to the first link 31421. The first shielding sub-cover 3131 is fixedly connected to the second link 31422. The second drive member 3141 simultaneously drives the two first shielding sub-covers 3131 to engage and block the light outlet 3112 or to disengage and open the light outlet 3112 via the two sets of linkage assemblies 3142. In this design, the simultaneous movement of the two first shielding sub-covers is achieved through an electric mechanism. Specifically, the second driving component 3141 drives the first connecting rod 31421, the first connecting rod 31421 drives the second connecting rod 31422, and the second connecting rod 31422 drives the first blocking sub-cover 3131 to rotate, so that the two first blocking sub-covers 3131 can either engage with each other to block the light outlet 3112 or separate with each other to open the light outlet 3112. This driving method is convenient, precise, efficient, and provides high motion consistency and operational efficiency. Specifically, as... Figure 10 As shown, the second driving component 3141 is a cylinder. Two first connecting rods 31421 are vertically arranged and connected to the transmission component of the cylinder, and the two second connecting rods 31422 are arranged in a figure-eight shape.

[0047] Optionally, such as Figure 10 As shown, a pin 31421a is provided on the first connecting rod 31421, and a movable hole 31422a is provided on the second connecting rod, in which the pin 31421a is movably inserted. In this design, the pin 31421a is movably inserted into the movable hole 31422a to prevent the first connecting rod 31421 and the second connecting rod 31422 from jamming. Specifically, the movable hole 31422a is an elongated hole.

[0048] Optionally, such as Figure 5 and Figure 6 As shown, the initial curing light-emitting mechanism 31 and the re-curing light-emitting mechanism 32 also include an outer main shell 315. The outer main shell 315 has a removable first mounting cavity with an open end, into which a first mounting shell 311 is removably inserted. In this design, the first mounting shell 311 can be easily removed from the outer main shell 315, facilitating replacement of the UV lamp 312 or maintenance. Specifically, the outer main shell 315 and the first mounting shell 311 are removably installed via a slide rail or similar structure.

[0049] Optionally, such as Figure 6As shown, the initial curing illumination mechanism 31 also includes a transparent quartz glass plate 316, which is correspondingly arranged with the light outlet 3112; the transparent quartz glass plate 316 is used to enhance the light intensity of the ultraviolet lamp 312. In this solution, by setting the transparent quartz glass plate 316, the light intensity of the ultraviolet lamp 312 can be enhanced, thereby improving the speed and effect of transfer curing.

[0050] Optionally, such as Figure 5 and Figure 6 As shown, the initial curing light-irradiation mechanism 31 also includes a first mounting base 463, on which a transparent quartz glass plate 316 is mounted. In this design, the transparent quartz glass plate 316 is mounted on the first mounting base 463, which is convenient to install and securely fixed. Specifically, the first mounting base 463 can be installed on both sides of the conveyor belt frame of the cold foil transfer equipment.

[0051] Optionally, the portion of the transfer carrier 5 at the inlet of the ultraviolet light irradiation mechanism 3 is inclined downwards at an angle of 40–70° relative to the horizontal plane. In this embodiment, the portion of the transfer carrier 5 at the inlet of the ultraviolet light irradiation mechanism 3 is inclined downwards, specifically at the inlet of the pre-curing light irradiation mechanism 31, at an angle of 40–70° relative to the horizontal plane. This facilitates the lifting by the upper lifting mechanism 4, resulting in greater compression, lifting force, and tension after lifting, and a tighter fit between the transfer carrier 5 and the transfer object 6. Specifically, the angle of inclination downwards relative to the horizontal plane is 60°.

[0052] Furthermore, such as Figure 1 , Figure 2 and Figure 11 As shown, adjusting seats 11 are provided on both sides of the transmission track 1, and adjusting roller shafts 12 are installed on the adjusting seats 11. The adjusting roller shafts 12 are installed on the adjusting seats 11 in an adjustable manner. The transfer carrier 5 is installed in a roll shape below the transmission track 1, so that the portion of the transfer carrier 5 at the entrance of the ultraviolet light irradiation mechanism 3 is tilted downwards. The adjusting roller shafts 12 support the transfer carrier 5 from below. The adjusting seats 11 have vertically extending elongated openings, and the two ends of the adjusting roller shafts 12 are installed in the elongated openings. Screws can be inserted from the top of the elongated openings and threaded to the two ends of the adjusting roller shafts, thereby realizing the vertical adjustment of the adjusting roller shafts 12. Of course, the vertical adjustment of the adjusting roller shafts 12 can also be achieved by other means.

[0053] The present invention also discloses a cold foil transfer method, applied to the cold foil transfer equipment as described above, including the following steps;

[0054] The transfer object 6 is fed onto the feeding mechanism 2 and passes through the ultraviolet irradiation mechanism 3 on the transport track 1; the transfer carrier 5 is fed onto the transport track 1 and passes through the ultraviolet irradiation mechanism 3.

[0055] The upper lifting mechanism 4 rises from below the transfer track 1 and lifts the transfer carrier 5 so that the transfer carrier 5 fits into the transfer object 6, completing the cold hot stamping transfer curing.

[0056] Furthermore, the cold foil stamping transfer method also includes the following steps: when the initial curing light-curing mechanism 31 is curing, the first driving component 461 drives the mounting frame 41 to reciprocate, so as to complete the change and reset of the lifting position when the upper lifting component 43 is lifted.

[0057] It should be noted that the limitations on each step involved in this solution are not considered as limiting the order of steps, provided that they do not affect the implementation of the specific solution. The steps listed first can be executed first, later, or even simultaneously. As long as this solution can be implemented, it should be considered to fall within the protection scope of this invention.

[0058] The above description, in conjunction with specific optional embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.

During the curing process of the ultraviolet light irradiation mechanism, the first driving component drives the mounting frame to reciprocate, so as to change and reset the lifting position when the upper component is lifted.
