[0030] like Figure 1-7As shown, a crystal label printer is characterized in that: it includes 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 vehicle assembly 3 that moves on the printer body 1 and sprays a pattern layer on the release paper, the printing vehicle assembly 3 includes a first nozzle 31 for spraying a self-adhesive glue layer on the release paper in sequence, a second nozzle 32 for spraying a white ink layer, a third nozzle 33 for spraying a color ink layer, and a fourth nozzle 34 for spraying a solidified varnish layer and a hot stamping varnish layer, and two coating assemblies 4 are provided at the output end of the printing area 2 on the printer body 1, which are respectively arranged to emboss a gold film on the hot stamping varnish layer and to cover a positioning film on the release paper pattern after embossing the gold film.

[0031] A control method for the crystal label printer, characterized in that:

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

[0033] S2, printing pattern layer: the 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 vehicle assembly 3 spray a self-adhesive glue layer, a white ink layer, a color ink pattern layer, and spray a curing varnish layer and a hot stamping varnish layer on the release paper respectively;

[0034] S3, embossing the gold film layer: the pattern layer of the release paper is attached to the gold film paper and sent to the front laminating assembly 4 for embossing, and the gold film paper is separated and recovered after embossing the gold film;

[0035] S4, laminating the positioning film: one side of the hot stamping pattern layer of the release paper and the positioning film are sent to the laminating component 4 on the rear side for embossing, and the positioning film is laminated on the release paper.

[0036] Specifically, during the printing process, when the release paper passes through the printing area 2 of the printer body 1, the printing vehicle assembly 3 moves and sprays a self-adhesive glue layer, a white ink layer, a color ink layer, a curing varnish layer and a hot stamping varnish layer on the release paper in sequence through the first nozzle 31, the second nozzle 32, the third nozzle 33 and the fourth nozzle 34. Among them, the white ink layer and the color ink layer constitute a color printing pattern. Then, when the release paper with the sprayed pattern passes through the front side coating assembly 4, the gold film of the gold film paper is pressed on the hot stamping varnish layer to achieve the hot stamping effect of the transfer pattern; finally, the hot stamping pattern is covered with a fitting positioning film through the rear side coating assembly 4.

[0037] When transferring the crystal label pattern to the product, tear off the release paper, then stick the positioning film together with the hot stamping pattern on the transfer product, and tear off the positioning film after pressing the hot stamping pattern layer to make the hot stamping pattern adhere to the transfer product. The transfer is convenient, there is no need to perform hot stamping on the pattern layer, and the hot stamping part of the pattern will not deviate.

[0038] like Figure 3 As shown, the curable varnish layer is a UV curable varnish layer, and a UV curing lamp 35 is provided on the printing vehicle assembly 3. The UV curable varnish layer is rapidly cured by the irradiation of the UV curing lamp 35.

[0039] like Figure 3-6 As shown, the laminating assembly 4 includes a driving shaft 41 disposed on the printer body 1, and a driven shaft 42 that cooperates with the driving shaft 41 for stamping. When stamping the gold film, the gold film paper is brought into contact with the hot stamping varnish on the pattern layer of the release paper, and the gold film paper and the release paper are driven by the driving shaft 41 to enter between the driving shaft 41 and the driven shaft 42, and the gold film is stamped on the hot stamping varnish layer under the stamping cooperation of the driving shaft 41 and the driven shaft 42 to achieve the hot stamping effect of the transfer pattern. Similarly, when covering and laminating the positioning film, the positioning film is covered on the release paper after the pattern is stamped, and the positioning film is stamped and laminated on the side of the pattern layer of the release paper through the cooperation of the driving shaft 41 and the driven shaft 42.

[0040] like Figure 3-7 As shown, the printer body 1 is provided with a pressure regulating assembly 5 for regulating the pressure between the driven shaft 42 and the driving shaft 41. The pressure regulating assembly 5 regulates the pressure between the driven shaft 42 and the driving shaft 41, so that the gold film is better transferred from the gold film paper to the hot stamping varnish of the release paper; similarly, the pressure regulating assembly 5 makes the pattern layer of the release paper better fit on the positioning film.

[0041] like Figure 4-7As shown, the pressure regulating assembly 5 includes a slide groove 51 arranged on both sides of the printer body 1, a slider 52 is arranged in the slide groove 51, and both ends of the driven shaft 42 are respectively arranged in the sliders 52 on both sides, and a pressure block 53 is arranged in the slide groove 51, one end of which is connected to the slider 52 and can move relative to each other to drive the slider 52 to move so that the driven shaft 42 is away from or close to the driving shaft 41, and a pressure spring 54 is arranged in the slide groove 51 between the slider 52 and the pressure block 53, and pressure is applied to the slider 52 through the pressure spring 54, thereby applying pressure to the driven shaft 42, thereby increasing the pressure between the driven shaft 42 and the driving shaft 41; a connecting rod 55 is arranged between the pressure blocks 53 on both sides, and a supporting block 56 is arranged on the pressure block 53 at the position where the connecting rod 55 extends, and a plurality of guide surfaces 57 are arranged eccentrically and around the outer side surface and respectively cooperate with the supporting block 56 to drive the pressure block 53 to move. When in use, the guide surface 57 is rotated by rotating the connecting rod 55, and the pressing block 53 moves upward under the cooperation of the guiding surface 57 and the supporting block 56, thereby driving the slider 52 connected at the lower side to compress the pressure spring 54 and move upward, thereby driving the driven shaft 42 to move upward, so that a gap is generated between the driven shaft 42 and the driving shaft 41, which is convenient for loading the gold film paper and the release paper, or for loading the positioning film and the release paper. Similarly, after the gold film paper and the release paper are loaded, or the positioning film and the release paper are loaded, the connecting rod 55 is rotated in the opposite direction, and the pressing block 53, the slider 52, and the driven shaft 42 move downward under the cooperation of the guiding surface 57 and the supporting block 5, so that the driven shaft 42 is pressed tightly against the driving shaft 41.

[0042] like Figure 5-6 As shown, a pressure nozzle 59 is provided between the pressure block 53 and the pressure spring 54, and a bolt 510 is provided on the pressure block 53, the lower end of which is connected to the pressure nozzle 59 and is used to adjust the pressure of the pressure spring 54. By rotating the bolt 510, the pressure nozzle 59 is driven to move, and the pressure of the pressure spring 54 on the pressure block 53 is adjusted, thereby adjusting the pressure between the driven shaft 42 and the driving shaft 41.

[0043] like Figure 4-7 As shown, round wrenches 58 are respectively provided at both ends of the connecting rod 55 for driving the connecting rod 55 to rotate the switching guide surface 57. By rotating the round wrench 58, the connecting rod 55 can be easily driven to rotate.

[0044] like Figure 1-2As shown, a release paper feed shaft 6 is provided at the input end of the printing area 2 on the printer body 1, and a film tearing shaft 7 for separating the release paper protective film is provided between the release paper feed shaft 6 and the input end of the printing area 2, and a release paper receiving shaft 8 is provided at the output end of the laminating component 4 on the rear side of the printer body 1; a gold film paper feed shaft 9 and a gold film paper receiving shaft 10 are respectively provided at the input and output ends of the laminating component 4 on the front side of the printer body 1; a positioning film feed shaft 11 is provided at the input end of the laminating component 4 on the rear side of the printer body 1. During the printing process, the release paper roll, the gold film paper roll and the positioning film roll are respectively arranged on the release paper unloading shaft 6, the gold film paper unloading shaft 9 and the positioning film unloading shaft 11. After the release paper is unloaded from the release paper unloading 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 is fed into the front coating component 4 together with the gold film paper. After the gold film paper is embossed and laminated, the waste gold film paper is recovered by the gold film paper receiving shaft 10. At the same time, the release paper after the gold film is embossed is fed into the rear coating component 4 together with the positioning film, and is wound up on the release paper receiving shaft 8 after the positioning film is embossed and laminated to the release paper.

[0045] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
