[0010] The crystal label printer described above is characterized in that: a connecting rod is provided between the two pressure blocks and passes through the pressure blocks; a support block is provided on the pressure block at the extension position of the connecting rod; and multiple guide surfaces are provided on the connecting rod, which are arranged around the outer side and cooperate with the support blocks to drive the pressure blocks to move.

[0011] The crystal label printer described above is characterized in that: both ends of the connecting rod are respectively provided with round wrenches for driving the connecting rod to rotate and switch the guide surface.

[0012] The crystal label printer described above is characterized in that: a pressure nozzle is provided between the pressure block and the pressure spring, and a bolt is provided on the pressure block with its lower end connected to the pressure nozzle for adjusting the pressure of the pressure spring.

[0013] The crystal label printer described above is characterized in that: a release paper feeding shaft is provided at the input end of the printing area on the printer body, and a film-tearing shaft for separating the release paper protective film is provided between the release paper feeding shaft and the input end of the printing area; a release paper receiving shaft is provided at the output end of the laminating assembly on the rear side of the printer body; a gold film feeding shaft and a gold film receiving shaft are respectively provided at the input and output ends of the laminating assembly on the front side of the printer body; and a positioning film feeding shaft is provided at the input end of the laminating assembly on the rear side of the printer body.

[0014] A control method for the above-mentioned crystal label printer, characterized in that: it includes...

[0015] S1. Prepare the pattern: Prepare the pattern in advance;

[0016] S2, Printing Pattern Layer: Release paper is fed into the printing area, and the first, second, third and fourth nozzles of the printing carriage assembly spray a self-adhesive layer, a white ink layer, a colored ink pattern layer, a cured varnish layer and a hot stamping varnish layer onto the release paper, respectively.

[0028] The technical solutions in the embodiments of the present invention will now be clearly and completely described in conjunction with the accompanying drawings.

[0029] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. Furthermore, descriptions involving "preferred," "second-best," etc., in this invention 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, a feature defined as "preferred" or "second-best" may explicitly or implicitly include at least one of those features.

[0030] As shown in Figures 1-7, a crystal label printer is characterized by comprising a printer body 1 and release paper. The printer body 1 is provided with a printing area 2 for the release paper to pass through, and a printing carriage assembly 3 that moves on the printer body 1 and sprays a pattern layer onto the release paper. The printing carriage assembly 3 includes a first nozzle 31 for sequentially spraying a self-adhesive layer onto the release paper, a second nozzle 32 for spraying a white ink layer, a third nozzle 33 for spraying a colored ink layer, and a fourth nozzle 34 for spraying a cured varnish layer and a hot stamping varnish layer. The printer body 1 is provided with two laminating assemblies 4 at the output end of the printing area 2, which are respectively used for pressing gold film onto the hot stamping varnish layer and for covering the release paper pattern with a positioning film after pressing gold film.

[0031] A control method for the above-mentioned crystal label printer, characterized in that: it includes...

[0032] S1. Prepare the pattern: Prepare the pattern in advance;

[0033] S2, Printing Pattern Layer: Release paper is fed into the printing area, and the first nozzle 31, the second nozzle 32, the third nozzle 33 and the fourth nozzle 34 of the printing carriage assembly 3 respectively spray a self-adhesive layer, a white ink layer, a colored ink pattern layer, and a sprayed curing varnish layer and a hot stamping varnish layer on the release paper.

[0034] S3, Imprinting the gold film layer: The pattern layer side of the release paper is bonded to the gold film paper and fed into the front coating component 4 for imprinting, and the gold film paper is separated and recycled after imprinting the gold film.

[0035] S4. Applying the positioning film: The hot stamping pattern layer of the release paper is pressed against the positioning film by the laminating assembly 4 on the back side, thus applying the positioning film onto the release paper.

[0036] Specifically, during the printing process, as the release paper passes through the printing area 2 of the printer body 1, the printing carriage assembly 3 moves and sequentially sprays a self-adhesive layer, a white ink layer, a colored ink layer, a curing varnish layer, and a hot stamping varnish layer onto the release paper via the first nozzle 31, the second nozzle 32, the third nozzle 33, and the fourth nozzle 34. The white ink layer and the colored ink layer together form a colored printed pattern. Subsequently, as the release paper with the pattern passes through the front laminating assembly 4, the gold film of the gold foil paper is imprinted onto the hot stamping varnish layer, achieving a hot stamping effect for the transferred pattern. Finally, the rear laminating assembly 4 covers the hot stamping pattern with a bonding and positioning film.

[0037] When transferring the crystal label pattern onto the product, peel off the release paper, then attach the positioning film along with the hot stamping pattern to the transferred product. After pressing the hot stamping pattern layer firmly, peel off the positioning film to adhere the hot stamping pattern to the transferred product. The transfer is convenient, does not require hot stamping of the pattern layer, and the hot stamping part of the pattern will not deviate.

[0038] As shown in Figure 3, the cured varnish layer is a UV-cured varnish layer. The printing carriage component 3 is equipped with a UV curing lamp 35, which irradiates the UV-cured varnish layer to cure it quickly.

[0039] As shown in Figures 3-6, the laminating assembly 4 includes a drive shaft 41 mounted on the printer body 1 and a driven shaft 42 that cooperates with the drive shaft 41 for pressing. During the gold foil imprinting process, the gold foil paper comes into contact with the hot stamping varnish on the release paper's pattern layer. Driven by the drive shaft 41, the gold foil paper and release paper are moved together between the drive shaft 41 and the driven shaft 42. The combined pressing action of the drive shaft 41 and the driven shaft 42 imprints the gold foil onto the hot stamping varnish layer, achieving a transfer pattern hot stamping effect. Similarly, when applying the positioning film, the positioning film is placed over the hot stamped release paper, and the drive shaft 41 and the driven shaft 42 work together to press and adhere the positioning film to the side of the release paper's pattern layer.

[0040] As shown in Figure 3-7, the printer body 1 is equipped with a pressure adjustment component 5 for adjusting the pressure between the driven shaft 42 and the drive shaft 41. By adjusting the pressure between the driven shaft 42 and the drive shaft 41 through the pressure adjustment component 5, the gold film can be better transferred from the gold film paper to the hot stamping varnish on the release paper; similarly, the pressure adjustment component 5 can make the release paper pattern layer better adhere to the positioning film.

[0041] As shown in Figures 4-7, the pressure regulating component 5 includes a slide groove 51 disposed on both sides of the printer body 1. A slider 52 is disposed in the slide groove 51. The two ends of the driven shaft 42 are respectively disposed in the sliders 52 on both sides. A pressure block 53 is disposed in the slide groove 51, with one end connected to the slider 52 and movable relative to it, for driving the slider 52 to move so that the driven shaft 42 moves away from or closer to the drive shaft 41. A pressure spring 54 is disposed in the slide groove 51 between the slider 52 and the pressure block 53. The pressure spring 54 applies pressure to the slider 52, thereby applying pressure to the driven shaft 42, thereby increasing the pressure between the driven shaft 42 and the drive shaft 41. A connecting rod 55 is disposed between the two pressure blocks 53 and passes through the pressure block 53. A support block 56 is disposed on the pressure block 53 at the extension position of the connecting rod 55. The connecting rod 55 is provided with multiple eccentrically disposed guide surfaces 57 arranged around the outer side and respectively cooperating with the support block 56 to drive the pressure block 53 to move. In use, rotating the connecting rod 55 drives the guide surface 57 to rotate. Under the action of the guide surface 57 and the support block 56, the pressure block 53 moves upward, thereby driving the slider 52 connected to the lower side to compress the pressure spring 54 and move upward, thereby driving the driven shaft 42 to move upward, creating a gap between the driven shaft 42 and the driving shaft 41. This facilitates the insertion of the gold film paper and release paper, or the positioning film and release paper. Similarly, after the gold film paper and release paper, or the positioning film and release paper, by rotating the connecting rod 55 in the opposite direction, under the action of the guide surface 57 and the support block 5, the pressure block 53, slider 52, and driven shaft 42 move downward, so that the driven shaft 42 is pressed tightly against the driving shaft 41.

[0042] As shown in Figures 5-6, a pressure nozzle 59 is provided between the pressure block 53 and the pressure spring 54. The pressure block 53 is provided with a bolt 510 whose lower end is connected to the pressure nozzle 59 for adjusting the pressure of the pressure spring 54. By rotating the bolt 510, the pressure nozzle 59 is moved, thereby adjusting the pressure of the pressure spring 54 on the pressure block 53, and thus adjusting the pressure between the driven shaft 42 and the driving shaft 41.

[0043] As shown in Figure 4-7, each end of the connecting rod 55 is provided with a round wrench 58 for rotating the connecting rod 55 to switch the guide surface 57. Rotating the round wrench 58 facilitates the rotation of the connecting rod 55.

[0044] As shown in Figures 1-2, the printer body 1 has a release paper feeding shaft 6 at the input end of the printing area 2, and a film-tearing shaft 7 for separating the release paper protective film between the release paper feeding shaft 6 and the input end of the printing area 2. The printer body 1 has a release paper receiving shaft 8 at the output end of the laminating assembly 4 located at the rear. The printer body 1 has a gold film feeding shaft 9 and a gold film receiving shaft 10 at the input and output ends of the laminating assembly 4 located at the front. The printer body 1 has a positioning film feeding shaft 11 at the input end of the laminating assembly 4 located at the rear. During the printing process, the release paper roll, the gold film paper roll, and the positioning film roll are respectively set on the release paper feeding shaft 6, the gold film paper feeding shaft 9, and the positioning film feeding shaft 11. After the release paper is fed from the release paper feeding shaft 6, the protective film of the release paper is torn off by the film tearing shaft 7 and then enters the printing area 2. After the pattern is printed, the release paper and the gold film paper are fed into the front laminating assembly 4 together. After the gold film paper is pressed and laminated, the gold film paper waste is recycled by the gold film paper take-up shaft 10. At the same time, the release paper after the gold film is pressed and laminated is fed into the rear laminating assembly 4 together with the positioning film. After the positioning film is pressed and laminated with the release paper, it is wound up on the release paper take-up shaft 8.

[0045] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct or indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
