Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a thermal transfer printing coating curing mechanism. Background Art

[0002] The thermal transfer film printer is a printing machine that prints single-color or multi-color patterns onto various types of base films. The printing process is as follows: the rolled transfer film base film is unrolled by the unwinding mechanism and then sent to the embossing device via the conveyor roller to be embossed and printed with the pattern. Finally, the unrolled transfer film base film is reeled up by the reeling mechanism to complete the entire printing process. During the printing and moving process of the base film, most of the coatings are cured by ultraviolet light. However, the light of the ultraviolet lamp is relatively dispersed during the irradiation process and will scatter throughout the curing device, resulting in uneven light intensity and range on the coating on the base film. During the irradiation process, the light cannot be concentrated and fully and evenly irradiated on the entire coating, affecting the curing effect of the coating and reducing production quality.

[0023] See also Figure 1-5 , the utility model provides a technical solution:

[0024] Embodiment 1:

[0025] A thermal transfer printing coating curing mechanism comprises a frame 1 and a curing box 2. The curing box 2 is arranged on the frame 1 and between the printing machine and the winding device, and is used for curing the printed base film. A plurality of lamp holders 5 are arranged equidistantly on the upper part of the inner cavity of the curing box 2. Ultraviolet curing lamps 6 are arranged on the plurality of lamp holders 5. By equidistantly arranging the plurality of ultraviolet curing lamps 6, full-range irradiation in the inner cavity of the curing box 2 is achieved. The lamp holders 5 are installed on a lifting mechanism, and the lifting mechanism is used for adjusting the irradiation height of the ultraviolet curing lamps 6.

[0026] Adjustment mechanisms 10 are symmetrically arranged on both sides of the ultraviolet curing lamp 6 , and the adjustment mechanisms 10 are used to adjust the irradiation range of the ultraviolet curing lamp 6 to improve the curing effect.

[0027] The lifting mechanism includes a lifting plate 4 and a first electric push rod 7. Lamp holders 5 are fixedly installed on both sides of the bottom of the lifting plate 4, and the top center of the lifting plate 4 is fixedly connected to the output end of the first electric push rod 7. The first electric push rod 7 is fixedly installed on the top plate 3 arranged on the upper part of the curing box 2.

[0028] The lifting mechanism further includes a first slide bar 8 and a first slide groove 9 . The first slide bar 8 is fixedly mounted at the four corners of the top surface of the lifting plate 4 , and the first slide bar 8 is slidably connected to the first slide groove 9 opened inside the top plate 3 .

[0029] In this embodiment, a lifting mechanism is provided to adjust the irradiation height of the ultraviolet curing lamp 6 and the distance between the ultraviolet curing lamp and the base film to ensure accurate irradiation intensity and improve the curing effect. The first electric push rod 7 is driven to lift and lower the ultraviolet curing lamp 6 at the bottom through the lifting plate 4 to ensure that the ultraviolet curing lamp 6 is located at a suitable irradiation position on the upper part of the base film, and the irradiation intensity of the light is adjusted to improve the uniformity of irradiation and curing.

[0030] Embodiment 2:

[0031] Based on the first embodiment, the adjustment mechanism 10 mentioned in the first embodiment is described as follows:

[0032] The adjusting mechanism 10 includes a light blocking plate 101, a second sliding bar 102, a slider 103 and a second electric push rod 104. The light blocking plate 101 is symmetrically arranged on the other two sides of the lifting plate 4, and the top of the light blocking plate 101 is rotatably connected to the other two sides of the lifting plate 4. The second sliding bar 102 is fixedly installed at the center of the outer side of the light blocking plate 101, and the second sliding bar 102 is slidably connected to the second sliding groove 13 inside one end of the slider 103. The other end of the slider 103 is rotatably connected to the second rotating seat 12 arranged at the output end of the second electric push rod 104, and the base of the second electric push rod 104 is rotatably connected to the first rotating seat 11 arranged on the top plate 3.

[0033] In this embodiment, by symmetrically arranging adjustment mechanisms 10 on both sides of the lifting plate 4, the irradiation range of the ultraviolet curing lamp 6 can be adjusted and controlled, thereby improving the curing efficiency, reducing energy waste, ensuring that the curing area of ​​the base film can be evenly and fully irradiated and cured, and improving the curing effect. The second electric push rod 104 is used to drive its output shaft to reciprocate. When the output shaft of the second electric push rod 104 is pushed outward, the slider 103 is pushed downward on the second slide bar 102 and drives the light blocking plate 101 to rotate inward, thereby narrowing and concentrating the irradiation range on both sides of the ultraviolet curing lamp 6. On the contrary, when the output shaft of the second electric push rod 104 contracts inward, the light blocking plate 101 expands outward to expand the irradiation range. By using the required adjustment control, it is ensured that the light source is concentrated on the base film, thereby improving the flexibility of the device and the curing effect and efficiency of the printed coating.

[0034] Inlet and outlet ports 14 are provided on both sides of the curing box 2 . The inlet and outlet ports 14 are used for conveying the base film, and guide rollers 15 are provided outside the inlet and outlet ports 14 .

[0035] Studs 18 are provided at the four corners of the top surface of the curing box 2. The studs 18 pass through the through slots 19 inside the top plate 3 and are threadedly connected with the nuts 20. By providing the studs 18 and the through slots 19, it is convenient to disassemble and assemble the top plate 3 and maintain the internal structure of the curing box 2.

[0036] A ventilation fan 16 is disposed on the upper portion of the curing box 2 , and a dustproof net 17 is disposed on the outer side of the ventilation fan 16 . Ventilation and heat dissipation inside the curing box 2 are achieved by arranging the ventilation fan 16 and the dustproof net 17 .

[0037] Working principle: First, the rolled transfer film base film is unrolled by the unwinding mechanism and then sent to the printing device for printing via the conveying roller. After printing, the coating is cured by the curing box 2. Finally, the unrolled transfer film base film is reeled by the reeling device. When the base film passes through the inner cavity of the curing box 2 through the guide roller 15 and the inlet and outlet 14, the height and irradiation range of the ultraviolet curing lamp 6 are first adjusted according to the width of the base film, and the height of the ultraviolet curing lamp 6 is adjusted by driving the first electric push rod 7. The height of the ultraviolet curing lamp 6 at the bottom of the lifting plate 4 is driven by the first electric push rod 7. The second electric push rod 104 is used to adjust and control the irradiation range of both sides of the ultraviolet curing lamp 6. The light shielding plates 101 on both sides of the lifting plate 4 are set to control and adjust the irradiation range of both sides of the entire light source, so as to ensure that the light source is concentrated on the base film passing through the inner cavity of the curing box 2, and the irradiation light intensity of the coating on the base film, the irradiation distance and coverage of the light source, and the curing time of the irradiation in the inner cavity of the curing box 2 are accurately controlled, thereby improving the curing effect and efficiency and ensuring the production quality.
