Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0031] In order to meet the needs of various printed materials and ensure printing quality, a device that can control the up and down position of the printing roller needs to be designed.

[0032] like Figure 1 , Figure 2 As shown, this utility model discloses an adjustable laser transfer printing roller device, including a support frame 1. A front hot press roller device 2, a main transfer roller 3, and a rear hot press roller device 4 are sequentially arranged on the support frame 1. The support frame 1 includes a base plate 11, a transfer support plate 12, and a laser film support plate 13. The front hot press roller device 2, the main transfer roller 3, and the rear hot press roller device 4 are respectively fixed on the transfer support plate 12. The transfer film device 5 and the UV lamp 6 are fixed on the laser film support plate 13. The transfer film device 5 is arranged above the main transfer roller 3, and the UV lamp 6 is arranged between the main transfer roller 3 and the transfer film device 5.

[0033] The printed material is fed into the front hot press roller device 2 from one end, and then passes through the front hot press roller device 2 in sequence. First, it undergoes initial hot press transfer. Then, it passes through the main transfer roller 3 and the UV lamp 6 above the main transfer roller 3 for UV ink curing. Then, it moves to the rear hot press roller device 4 for secondary hot press and ink replenishment transfer. The ink on the laser film is fully transferred to the printed material. At the same time, heating can be performed to accelerate drying.

[0034] like Figures 2-4 As shown, in order to control the positions of the front hot press roller device 2 and the rear hot press roller device 4 and to facilitate the adjustment of the thickness and pressure during printing, the front hot press roller device 2 of this utility model includes a front hot press roller 21 and a front hot press roller control device 22, and the rear hot press roller device 4 includes a rear hot press roller 41 and a rear hot press roller control device 42.

[0035] like Figures 3-4 As shown, the transfer film device 5 includes two laser film rollers 51 and multiple laser transfer turning rollers 52. Each laser film roller 51 is equipped with a film drive motor 511 at its end. A laser film 53 is wound and connected between the two laser film rollers 51. The film drive motors 511 of the two laser film rollers 51 are in the same direction. One laser film roller 51 is responsible for unwinding and releasing the unprinted laser film 53, while the other laser film roller 51 is responsible for winding up and rewinding the remaining laser film 53 after printing.

[0036] In order to better adjust the tension of the laser film 53 and transfer it onto the printed material with a more suitable tension, a tension adjustment roller 54 is also provided in the transfer film device 5. The tension adjustment roller 54 is used to adjust the tension of the laser film 53.

[0037] Six laser transfer turning rollers 52 are arranged in the middle and symmetrically in two groups on the laser film support plate 13. The tension adjusting roller 54 is located between the two groups of laser transfer turning rollers 52. Several other laser transfer turning rollers 52 are respectively set at the turning position to change the position of the laser film 53.

[0038] The tension adjusting rod 54 has adjusting rods 55 at both ends, and sliding blocks 56 that can move up and down are provided on the adjusting rods 55. The two ends of the tension adjusting rod 54 are fixed to the sliding blocks 56. The sliding blocks 56 are also provided with locking and limiting devices, which can be screws or snap-fit ​​structures, so that the position of the adjusting rods 55 can be fixed after the tension of the laser film 53 is adjusted.

[0039] By setting an adjustable tension adjustment roller 54, the tension of the laser film 53 can be adjusted so that the ink on the laser film adheres to the printed matter with appropriate tension, thereby improving the final printing effect.

[0040] likeFigures 2-3 As shown, the laser film 53 is sequentially wound onto the front hot press roller 21, the main transfer roller 3, and the rear hot press roller 41. The front hot press roller control device 22 and the rear hot press roller control device 42 adjust the degree of adhesion between the laser film 53 and the main transfer roller 3 by controlling the front hot press roller 21 and the rear hot press roller 41, respectively.

[0041] Specifically, such as Figure 4 As shown, the front hot press roller 21 is provided with front movable connecting bearings 211 at both ends. The front hot press roller control device 22 includes a front L-shaped movable rod 221, a front transfer bearing 222 and a front drive device 23. The front drive device 23 controls the distance between the front hot press roller 21 and the main transfer roller 3 by controlling the rotation angle of the front L-shaped movable rod 221.

[0042] The front drive unit 23 includes a roller drive cylinder 231 and a front linear lead screw 232, with the piston rod of the front linear lead screw 232 hinged to the lower rod 2212. Since the front heating pressure roller 21 is the most important component responsible for the entire printing process, its position needs precise control. The servo cylinder 232 provides stable power output, while the force pushing the front servo lead screw 231 is uniform and gentle, preventing the front heating pressure roller 21 from exerting excessive impact on the laser film 53.

[0043] The rear hot press roller 41 is provided with rear movable connecting bearings 411 at both ends. The rear hot press roller control device 42 includes a rear L-shaped movable rod 421, a rear adapter bearing 422 and a rear drive device 43, which is a cylinder.

[0044] like Figure 5 As shown, the front L-shaped movable rod 221 includes an upper rod 2211 and a lower rod 2212, with an angle of 60-120 degrees between the upper rod 2211 and the lower rod 2212. Both the upper rod 2211 and the lower rod 2212 are fixed on the outer ring of the front transition bearing 222. The movable connecting bearing 211 is hinged to the upper end of the upper rod 2211, and the front drive device 23 is hinged to the lower end of the lower rod 2212.

[0045] By setting adjustable front and rear heating rollers, the printing gap between the front heating roller and the main suction steel roller can be precisely adjusted according to the thickness and material of the printed matter. This makes it suitable for printing materials of various thicknesses and meets the printing processing needs of various materials. At the same time, the adjustable pressure of the front heating roller ensures that the printed pattern on the laser film makes full contact with the printed matter under pressure, avoiding problems such as ink overflow and pattern mess due to excessive pressure, or insufficient ink transfer and ink residue due to insufficient pressure.

[0046] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0047] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
