Description

Technical Field

[0001] This utility model relates to an embossing machine, specifically to a UV laminating machine. Background Technology

[0002] A UV laminator is a device that uses ultraviolet (UV) curing technology. It is mainly used for embossing on various material surfaces, such as paper, plastic, and leather, creating patterns or text with three-dimensional effects (such as embossing). The working principle involves applying pressure to the material using a mold while simultaneously irradiating it with a UV lamp, causing the UV ink or adhesive coating to cure instantly, thus quickly setting a clear and exquisite embossed effect. This machine is widely used in industries such as packaging printing and decorative materials. However, existing UV laminators still have many shortcomings in practical applications, mainly in the following aspects:

[0003] Many existing devices use a single or a small number of dispensing valves, resulting in uneven distribution of UV adhesive on the mold. This is especially problematic for complex patterns or high-precision applications, making it difficult to achieve accurate dispensing and affecting printing quality.

[0004] Traditional equipment lacks precise control over the clamping force and rolling speed during the pressing process, and cannot make dynamic adjustments according to different adhesive properties and mold requirements, resulting in uneven imprinting or mold damage.

[0005] Many devices have UV curing lamps that cannot cover the entire imprinting area, resulting in uneven distribution of ultraviolet light on the mold, which affects the polymerization reaction and curing effect of the UV adhesive. Utility Model Content

[0030] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0031] like Figures 1-3 As shown, a UV laminating machine of this utility model includes:

[0032] The host 1 is equipped with a horizontal moving module, and the movable end of the horizontal moving module is fixed with a conveyor table 4, and a mold is fixed on the conveyor table 4.

[0033] The glue application device 2 is located above the main unit 1 and is used to apply glue to the mold on the conveyor table 4.

[0034] Curing module 3 is located above one end of the main unit 1 and cures the mold on the conveyor table 4 through a curing device.

[0035] The horizontal moving module includes a drive motor and a transmission rod, with the drive motor connected to the transmission rod. The drive motor drives the transmission rod to rotate, thereby moving the movable block on the transmission rod. The conveyor table 4 is installed above the movable block.

[0036] The adhesive applicator 2 includes a linear drive guide rail 5, a mounting plate 6, a connecting rod 7, and multiple precision dispensing valves 8, all located above the main unit 1.

[0037] The mounting plate 6 is fixed to the movable end of the linear drive guide rail 5. A lifting cylinder 9 is fixed on the mounting plate 6 and is fixed to the output shaft of the lifting cylinder 9. The multiple precision dispensing valves 8 are evenly installed on the connecting rod 7 and correspond to the position of the conveyor table 4. The precision dispensing valves 8 are used to dispense glue onto the mold.

[0038] The curing module 3 includes a pressure roller assembly, a UV curing lamp assembly, and a cover plate 10.

[0039] The cover plate 10 is fixed above one end of the main unit 1, and the UV curing lamp assembly is disposed inside the cover plate 10. When the conveyor table 4 is placed inside the cover plate 10, the UV curing lamp assembly corresponds to the mold position. The pressure roller assembly is disposed at the front end of the cover plate 10 and corresponds to the mold position of the conveyor table 4.

[0040] In order to achieve the effect of pressing and curing, in this embodiment, the pressure roller assembly includes a pressing cylinder 11 and a pressing roller 12;

[0041] The pressing roller 12 is mounted on the output shaft of the pressing cylinder 11 via the connecting seat 13, and guide rods are provided on both sides above the connecting seat 13; the cover plate 10 is provided with guide seats corresponding to the guide rods, and the guide rods are guided by the guide seats.

[0042] To accelerate curing, in this embodiment, the UV curing lamp includes multiple UV curing lamp plates 14, and the UV curing lamp plates 14 correspond to the position of the mold.

[0043] For ease of control, in this embodiment, a human-machine interface panel 15 is provided on the cover plate 10, and the human-machine interface panel 15 is connected to the control drive motor, the linear drive guide rail 5, the precision dispensing valve 8, the pressing cylinder 11 and the UV curing lamp plate 14 for operation.

[0044] The prepared mold is installed in the groove on the conveyor table and secured. The conveyor table moves linearly via a water bottle moving module. When the mold passes under the glue applicator, the lifting cylinder of the glue applicator drives the connecting rod downward, bringing the precision dispensing valve close to the mold and dispensing glue evenly and at intervals in the direction of the mold's movement. The dispensing position and amount of glue need to be precisely controlled according to the pattern of the mold and product requirements to ensure the subsequent imprinting effect. The prepared board is placed on the mold coated with UV glue, and the board is gently pressed by hand to initially disperse the UV glue so that the glue can be more evenly distributed on the mold during the subsequent rolling process. The mold continues to move under the pressure roller, and the driving cylinder drives the pressure roller downward and squeezes the board, so that the UV glue is evenly coated on the mold. The pressure and rolling speed of the pressure roller need to be adjusted according to the properties of the glue and the requirements of the mold to ensure that the glue can fully fill the pattern or texture of the mold without damaging the board and the mold. The mold continues to move into the enclosure, where the UV curing lamp assembly emits ultraviolet light to irradiate the mold and board coated with UV glue. Under ultraviolet light, the adhesive undergoes a rapid polymerization reaction, quickly solidifying and transforming from a liquid to a solid state. It adheres firmly to the board, forming a shape identical to the mold pattern or texture. The duration and intensity of the light exposure need to be controlled based on the type and thickness of the UV adhesive to ensure complete curing. After the mold is removed from the main unit, it continues to move under the punching machine. The punching machine removes any excess UV adhesive that overflows from the mold edge, resulting in neat, smooth edges that meet the product's design requirements. The punching force and position need precise control to avoid damaging the product. The solidified UV adhesive is then removed from the mold through the board, completing the demolding process.
