Description

Technical Field

[0001] The invention relates to a mercury lamp light box, in particular to a heat dissipation and energy-saving UV mercury lamp light box. Background Art

[0002] In recent years, UV light-curing inks have been used more and more in both the screen printing industry and the offset printing industry. Compared with traditional solvent-based inks, UV-curing inks have the advantages of good gloss and strong three-dimensional effect. Especially in terms of ink drying, UV light-curing inks are cured under the irradiation of UV light sources, avoiding the shortcomings of traditional solvent-based inks such as long drying cycles and large floor space occupied by drying devices. At present, the main light sources for CTP printing ink curing are UV mercury lamps or halogen lamps. During operation, mercury lamps generate a lot of heat, which will have adverse effects on printed products, such as bubbling and cracking. Therefore, when using mercury lamps, certain heat dissipation devices are required. In addition, temperature has a great influence on the working state of mercury lamps. If the temperature is too high, the lamp tube will be heated and bulged. If the temperature is too low, the power of the lamp tube cannot be increased, and the intensity of the ultraviolet rays emitted is not enough to dry the ink.

[0003] When a traditional mercury lamp light box is working, the heat dissipation of the mercury lamp light box is very slow, the heat dissipation effect is not very good, and the temperature is still very high when working. The energy utilization rate of the mercury lamp when working is very low.

[0004] The public document with the publication number of "CN 204516301U" discloses a "heat-insulated lamp box with mercury light source", which uses some heat-insulating devices to prevent the heat generated by the mercury lamp from affecting the printed matter, which is a certain improvement over the traditional process. However, the above-mentioned defects still exist. Summary of the invention

[0026] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0027] like Figures 1 to 6 As shown, a heat-dissipating and energy-saving UV mercury lamp light box, a heat-dissipating and energy-saving UV mercury lamp light box, comprises a shell 1 and a lamp holder 2, the shell 1 is a rectangular parallelepiped structure, one end of the shell 1 is a closed end, and the other end of the shell 1 is an open end, a plurality of first ventilation holes 11 are arranged on the side of the shell 1, a fan for generating negative pressure is arranged on the open end, and the positions of the first ventilation holes 11 correspond to the lamp holder 2 for dissipating heat to the lamp holder 2; the lamp holder 2 is arranged inside the shell 1, a mercury lamp 21 is arranged inside the lamp holder 2, focusing glasses 22 for reflecting ultraviolet rays are respectively arranged on the top and sides of the lamp holder 2, and heat-insulating glass through which ultraviolet rays can pass is arranged on the bottom of the lamp holder 2.

[0028] When the mercury lamp is working, the negative pressure generated by the fan causes the air inside the housing 1 to flow through the first ventilation hole 11 to dissipate heat, and the speed of heat dissipation is controlled by controlling the negative pressure generated by the fan to meet the working state of the mercury lamp 21 in different environments; at the same time, the ultraviolet rays emitted by the mercury lamp 21 at 360° can be focused by the focusing glass 22 and act on the printed matter, which improves work efficiency and saves energy, while the heat-insulating glass can reduce the loss of heat energy, while maintaining a stable temperature without hindering the penetration of ultraviolet rays. The focusing glass 22 is a curved surface structure, and the heat-insulating glass is also a curved surface structure. The focusing glass 22 and the heat-insulating glass together form a hollow cylindrical structure. When working, the heat-insulating glass is located at the bottom, and when the printed matter passes under the heat-insulating glass, the ultraviolet rays emitted by the mercury lamp dry the printed matter. The heat-insulating glass can also be made into a flat structure.

[0029] In order to further improve the heat dissipation effect, a ventilation duct 12 is provided between the lamp holder 2 and the top of the outer shell 1, and a plurality of second ventilation holes 13 are respectively provided on the top and the side of the outer shell 1. The second ventilation holes 13 are connected to the ventilation duct 12. The first ventilation holes 11 are mainly for dissipating heat inside the lamp holder 2, and the second ventilation holes 13 are for dissipating heat to the outer shell 1, and of course, indirectly dissipating heat to the lamp holder 2.

[0030] A lampshade 23 is provided in the lamp holder 2, and the shape of the lampshade 23 corresponds to the shape of the heat-insulating glass. Specifically, the lampshade 23 is a curved surface structure, and the ends of the lampshade 23 are hingedly connected to the two ends of the mercury lamp 21. One end of the lampshade 23 is rotatably connected to the lamp holder 2, and the other end of the lampshade 23 is transmission-connected to a driving mechanism for rotating the lampshade 23, and the driving mechanism is a motor. Preferably, the driving mechanism is a cylinder.

[0031] In this embodiment, the installation and adjustment of the mercury lamp 21 are very convenient. Mercury lamp fixing devices are respectively provided at both ends of the mercury lamp 21, and the mercury lamp fixing device includes a mercury lamp fixing frame 211 and a lamp holder clamp 212, and the lamp holder clamp 212 is used to fix the mercury lamp 21, and the lamp holder clamp 212 and the mercury lamp fixing frame 211 are detachably connected. Specifically, the lamp holder clamp 211 is formed by folding a strip-shaped clip in half, and a hole for screws to pass through and fix is ​​provided at the folded portion, and the clip formed by folding in half is used to fix the mercury lamp 21, and the mercury lamp fixing frame 211 is "T"-shaped, and the lamp holder clamp 212 is fixedly connected to the mercury lamp fixing frame 211 by screws, and a "T"-shaped groove 26 corresponding to the mercury lamp fixing frame 211 is provided on the lamp holder 2, and the mercury lamp 21 is slidably fixed on the "T"-shaped groove 26 through the mercury lamp fixing device. When installing, removing or adjusting the mercury lamp 21, the mercury lamp fixing frame 211 can be slid in the "T"-shaped groove 26 to be adjusted to a position suitable for installing the mercury lamp 21, and then the lamp holder clamp 212 and the mercury lamp 21 can be installed and fixed in sequence.

[0032] For easy installation, a slide rail 14 is provided at the bottom of the housing 1, and a slide groove corresponding to the slide rail 14 is also provided at the bottom of the housing 1. The housing 1 is slidably connected to the slide rail 14 through the slide groove, and a working channel 15 for the passage of printed materials is provided between the housing 1 and the slide rail 14. When the mercury lamp 21 needs to be repaired or installed, the housing 1 can be pushed open by pushing the housing 1.

[0033] The housing 1 is also provided with a light shielding plate 24, which is perpendicular to the side of the housing 1 and is arranged above the working channel 15 to block the light emitted by the mercury lamp 21. When the mercury lamp 21 is working, the ultraviolet rays emitted are very strong and dazzling, and the setting of the light shielding plate 24 can prevent the ultraviolet rays from hurting the eyes.

[0034] In order to further improve the cooling effect, a water cooling device is provided at the bottom of the slide rail 14. The water cooling device includes a cooling shell 25. A water cooling pipe 251 is provided in the cooling shell 25. The water cooling pipe 251 is connected to the external water supply system. When the mercury lamp 21 is working, the water flowing in the water cooling pipe 251 can further dissipate the heat of the lamp holder 2, which has a better heat dissipation effect. Moreover, the stability of water cooling is relatively stable, and can generally be maintained at around 23°C, which is conducive to improving the drying effect of the mercury lamp 21. A plurality of air outlets 252 are provided at the top of the water cooling shell, and at least one air blowing hole 253 is provided at the end of the cooling shell 25. By blowing air from the air blowing hole 253, gas is ejected from the air outlet 252 during operation, disturbing the water molecules in the air and preventing them from being liquefied by cold on the water cooling shell 25.

[0035] In summary, the present invention has the following advantages:

[0036] 1. The focusing glass 22 is installed, which greatly improves the utilization rate of the ultraviolet rays emitted by the mercury lamp 21;

[0037] 2. The opening and closing of the lampshade 23 is controlled by the driving mechanism, which is convenient and quick and reduces mechanical fatigue;

[0038] 3. The ventilation duct 12 is designed with advanced technology, which makes the temperature lower than the mercury lamp box on the market;

[0039] 4. Easy to install and disassemble, easy to replace and inspect;

[0040] 5. The position of the mercury lamp 21 can be adjusted at will, and the mercury lamp 21 is more versatile;

[0041] 6. The new cooling method of upper air cooling and lower water cooling is adopted to reduce the overall temperature of the light box, making it easy to control a stable temperature, which is beneficial to improving the efficiency of the mercury lamp 21 drying and improving the effect.

[0042] 7. By designing the air holes 253 and the air outlet holes 252, water molecules in the air are disturbed to minimize liquefaction.

[0043] The above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Any modification or equivalent substitution that does not depart from the spirit and scope of the present invention shall be included in the scope of the technical solution of the present invention.
