[0032] A control method applied to the above water sticker printing device, characterized in that it comprises

[0033] S1, preparing a pattern: preparing a pattern in advance;

[0034] S2, printing the pattern layer: the transfer paper is sent into the printing area, and the first nozzle, the second nozzle, the third nozzle and the fourth nozzle of the printing car assembly are used to spray the hot-melting resin layer, the white ink layer, the color ink pattern layer, and the curing varnish layer and the gold foil varnish layer on the water-soluble coating layer side of the transfer paper in sequence;

[0035] S3, pressing the gold film layer: the pattern layer side of the transfer paper is laminated with the gold film paper and sent into the gold film laminating assembly for pressing, and the gold film paper is separated and recycled after pressing the gold film;

[0036] S4, laminating the positioning film: the gold foil pattern layer side of the transfer paper is laminated with the positioning film and sent into the positioning film laminating assembly for pressing, and the positioning film is laminated on the transfer paper.

[0037] Specifically, during the printing process, when the transfer paper passes through the printing area 2 of the printer main body 1, the printing car assembly 3 moves and sprays the hot melt resin layer, the white ink layer, the color ink layer, and the curing varnish layer and the gold foil varnish layer on the water-soluble coating side of the transfer paper in turn. Among them, the white ink layer and the color ink layer form a color printing pattern. Subsequently, the transfer paper after spraying the pattern layer passes through the gold film laminating assembly 4 to press the gold film of the gold film paper on the gold foil varnish layer, realizing the gold foil effect of the transfer pattern; finally, the positioning film laminating assembly 5 is used to press and cover the positioning film on the gold foil pattern.

[0038] When the water sticker pattern is transferred to the product, the positioning film is torn off, then the back of the transfer paper is dipped in water, and after waiting for a period of time when the transfer pattern is clearly visible, the transfer paper is pasted on the transfer product, after the bubbles are squeezed out, the transfer paper is naturally air-dried, and finally the transfer pattern is adhered to the transfer product after the transfer paper is torn off. The water transfer pattern has a gold foil effect, is light and thin, and can keep the product surface smooth, does not need to manufacture a printing screen, and the pattern does not need to be fixed and can be personalized and printed.

[0039] As shown in Figures 3-6 The gold film laminating assembly 4 is provided with a gold film heating assembly 14 for heating the gold film laminating assembly 4. In the present case, the structure of the positioning film laminating assembly 5 is the same as that of the gold film laminating assembly 4, and the structure of the positioning film heating assembly 6 is the same as that of the gold film heating assembly 14. During the printing process, in the case of low ambient temperature, the positioning film laminating assembly 5 is heated by the gold film heating assembly 14, so that the gold film is better pressed on the gold foil varnish layer when the transfer paper and the gold film paper pass through the heated positioning film laminating assembly 5; similarly, the positioning film laminating assembly 5 is heated by the positioning film heating assembly 6, so that the positioning film is better adhered to the transfer paper when the heated positioning film laminating assembly 5 presses and covers the positioning film, avoiding the problem of mutual displacement between the positioning film and the transfer paper due to not being tightly adhered.

[0040] As shown in Figures 4-6As shown, the gold film laminating assembly 4 includes a gold film laminating driving shaft 41 arranged on the printer body 1, and a gold film laminating driven shaft 42 cooperating with the gold film laminating driving shaft 41 for stamping. The positioning film laminating assembly 5 includes a positioning film laminating driving shaft 51 arranged on the printer body 1, and a positioning film laminating driven shaft 52 cooperating with the positioning film laminating driving shaft 51 for stamping. Therefore, when stamping the gold film, the gold film paper is contacted with the gold stamping varnish on the pattern layer of the transfer paper, and the gold film paper and the transfer paper are driven into the gold film laminating driving shaft 41 and the gold film laminating driven shaft 42 under the driving of the gold film laminating driving shaft 41, so that the gold film is stamped on the gold stamping varnish layer to achieve the gold stamping effect of the transfer pattern. Similarly, when covering the positioning film, the positioning film is covered on the transfer paper after the pattern is gold stamped, and the positioning film is tightly attached to the side of the pattern layer of the transfer paper through the cooperation of the positioning film laminating driving shaft 51 and the positioning film laminating driven shaft 52.

The gold film heating assembly 14 includes a gold film heating tube 141 arranged in the gold film laminating driven shaft 42, and a gold film temperature detection probe 142 arranged near the gold film laminating driven wheel bearing 43. The printer body 1 is provided with a positioning film laminating driven wheel bearing 53, and the two ends of the positioning film laminating driven shaft 52 are arranged in the positioning film laminating driven wheel bearing 53. The positioning film heating assembly 6 includes a positioning film heating tube 61 arranged in the positioning film laminating driven shaft 52, a positioning film temperature detection probe 62 arranged near the positioning film laminating driven shaft 52, and a heating control component 63 connected with the positioning film heating tube 61 and the positioning film temperature detection probe 62 for controlling the heating of the gold film heating tube 141 and the positioning film heating tube 61. Therefore, when the ambient temperature is too low and heating is needed, the gold film heating tube 141 and the positioning film heating tube 61 are controlled to work by the heating control component 63, so as to heat the gold film laminating driven shaft 42 and the positioning film laminating driven shaft 52 respectively, so that the gold film is better stamped on the gold stamping varnish layer to achieve the gold stamping effect, and the positioning film is more tightly attached to the transfer paper. The heating control component 63 controls the heating of the gold film heating plate 141 and the positioning film heating tube 61 according to the feedback temperature of the gold film temperature detection probe 142 and the positioning film temperature detection probe 62.

During printing, when the transfer paper passes through the tension rod 71, the tension rod 71 is pulled to move to make the tension rod 71 approach the proximity switch, so that the gold film paper collecting motor 121 works to make the gold film paper collecting shaft 12 rotate to recover the gold film waste paper, so that the gold film paper is in a fully open state. Among them, the groove 72 and the pulley 74 are used to limit the movement space of the tension rod 71; the guide rack 73 and the tension rod gear 74 cooperate to make the tension rod 71 in a rotating state during movement, avoiding the tension rod 71 from wrinkling the gold film paper during movement to affect the gold stamping effect; the spring 77 cooperates with the sliding block 76 to limit the maximum movement position of the tension rod 71.
