Technical Field

[0001] The utility model relates to the technical field of LED curing, in particular to a high-uniformity LED curing device. Background Art

[0002] UV printing is a printing method that uses LED ultraviolet lamps to cure inks and is widely used in packaging, labeling, commercial printing and graphic arts.

[0003] During the UV printing process, the paper to be cured is generally placed on a curing platen and then irradiated with an LED ultraviolet lamp to achieve the ink curing effect.

[0004] At present, since the thickness of each batch of paper to be cured will be different, and the effective irradiation and curing distance between the LED ultraviolet lamp and the paper to be cured is optimal at 50 mm, most of the existing LED curing devices for UV printing are unable to adjust the height dimensional accuracy of the LED ultraviolet lamp for papers of different thicknesses to be cured. Moreover, the existing LED curing devices for UV printing generally use a single LED ultraviolet lamp for irradiation, which cannot evenly distribute the ultraviolet irradiation light, thereby reducing the curing uniformity of the LED curing devices for UV printing for the paper to be cured as a whole.

[0005] The above problems are widespread and urgently need to be improved. Utility Model Content

[0006] The purpose of the utility model is to solve the above-mentioned shortcomings in the prior art and to propose a high-uniformity LED curing device.

[0012] Furthermore, there are four light diffusing plates, which are tilted at the lower corners of the curing irradiation box. The angle between the light diffusing plates and the horizontal plane is forty-five degrees. The light diffusing plates are made of high molecular weight polycarbonate and the lower end surface is not lower than the lower end surface of the LED ultraviolet lamp.

[0013] Furthermore, the heat sink has a thickness of five to six millimeters and is made of red copper, and the lower end of the heat sink is embedded in the curing irradiation box.

[0014] Furthermore, there are nine heat sinks arranged longitudinally, and there are five heat dissipation holes arranged transversely and penetrating each heat sink longitudinally.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-5 A high uniformity LED curing device comprises a curing table 1, on which a transmission bolt 11 and an adjusting cylinder 2 are provided, on which a pressure plate 12 is provided, on which an adjusting cylinder 2 is provided, and on which a lifting plate 21 is provided, on which a size scale plate 13 is provided on the curing table 1, on which a curing irradiation box 4 and a mounting strip 3 are provided on the lifting plate 21, on which a through opening 41 is provided on the curing irradiation box 4, in which a heat sink 5 is provided in the through opening 41, and on which heat sink 5 is provided with heat dissipation holes 51, on which an LED ultraviolet lamp 7 and a light expansion plate 6 are provided on the curing irradiation box 4, and on which a laser head 31 is provided on the mounting strip 3. The ultraviolet irradiation curing technologies recorded in this patent are all prior art, wherein the LED ultraviolet lamp 7 is an irradiation curing lamp for ultraviolet irradiation curing, and is prior art.

[0026] The laser heads 31 described in this patent are all prior art. The laser heads 31 can emit laser beams horizontally. The laser power will not burn the size scale plate 13, and the laser head 31 irradiates the size scale plate 13. The size scale plate 13 has scale values, so as to realize precise size adjustment display of the LED ultraviolet lamp 7 when it is raised and lowered.

[0027] In detail, a bearing 10 is embedded in the curing platen 1, and the mounting hole of the bearing 10 is fixedly sleeved with a transmission bolt 11. The transmission bolt 11 is threadedly connected to the pressure plate 12. The bearing 10 is a ball bearing, and the bearing 10 enables the transmission bolt 11 to rotate and prevents it from detaching from the curing platen 1.

[0028] Furthermore, the curing irradiation box 4 is a square structure as a whole, and the cross-section of the through-hole 41 is a square opening and longitudinally penetrates the curing irradiation box 4, which not only greatly reduces the weight of the curing irradiation box 4 and improves the lightweight of the curing irradiation box 4, but also further improves the effective heat dissipation of the heat sink 5.

[0029] Furthermore, the laser head 31 is horizontally installed at the left end of the mounting bar 3. An emission port 311 is provided on the laser head 31. The emission port 311 is horizontally aligned with the LED ultraviolet lamp 7 to ensure the effect of adjusting the optimal fifty-millimeter spacing between the LED ultraviolet lamp 7 and the paper to be cured later.

[0030] In more detail, there are four light expansion plates 6 which are respectively arranged obliquely at the lower corners of the curing irradiation box 4 . Combined with the inclination angle, the ultraviolet light emitted by the LED ultraviolet lamp 7 can be effectively expanded.

[0031] The angle between the light diffusing plate 6 and the horizontal plane is forty-five degrees. The light diffusing plate 6 is made of high molecular weight polycarbonate and the lower end surface is not lower than the lower end surface of the LED ultraviolet lamp 7, ensuring the contact effect between the lower end surface of the LED ultraviolet lamp 7 and the upper end surface of the paper to be cured by adjusting the cylinder 2 in the later stage.

[0032] The surface of the high molecular weight polycarbonate material is flat and smooth, with excellent light conductivity, impact resistance and high temperature resistance, low cost and light weight.

[0033] In general, the heat sink 5 is five to six millimeters thick and is made of red copper. The lower end of the heat sink 5 is embedded in the curing irradiation box 4. The red copper material has excellent thermal conductivity, and combined with the curing irradiation box 4 made of aluminum alloy, it can achieve rapid heat conduction.

[0034] Finally, there are nine heat sinks 5 arranged vertically, and five heat dissipation holes 51 arranged horizontally and vertically penetrate each heat sink 5, so as to achieve effective heat conduction and rapid dissipation of the heat generated by the LED ultraviolet lamp 7.

[0035] Working method: Place the paper to be cured by ultraviolet irradiation on the curing table 1. Take the pressure plate 12 on the right as an example. Hold the pressure plate 12 with one hand and turn the transmission bolt 11 counterclockwise with the other hand. The pressure plate 12 is driven to move downward through the threaded transmission and stably press the paper to be cured. Similarly, the pressure plate 12 on the left can also stably press the paper to be cured. Then start the adjusting cylinder 2 and the laser head 31. The emission port 311 of the laser head 31 will emit laser laterally toward the size scale plate 13. The started adjusting cylinder 2 will drive the curing irradiation box 4 and the mounting strip 3 to move downward as a whole through the lifting plate 21, thereby driving the laser emitted by the emission port 311 to move downward along the left end face of the size scale plate 13. The lower end face of the LED ultraviolet lamp 7 in the irradiation box 4 to be cured is aligned with the paper to be cured. After the upper end surface of the clamped paper to be cured is in contact, the adjusting cylinder 2 is stopped and the scale value of the size scale plate 13 currently irradiated by the laser is recorded. Then the adjusting cylinder 2 is started to drive the LED ultraviolet lamp 7 and the laser head 31 to move upward stably as a whole. When the difference between the current scale value of the size scale plate 13 irradiated by the laser head 31 and the previous scale value is fifty millimeters, the adjusting cylinder 2 is stopped and the LED ultraviolet lamp 7 is started. At this time, the distance between the LED ultraviolet lamp 7 and the paper to be cured currently to be irradiated and cured is fifty millimeters, which is the optimal curing distance. At the same time, the nine horizontally arranged LED ultraviolet lamps 7 simultaneously perform ultraviolet irradiation and curing on the paper to be cured below, and combine with the light expansion plate 6 to perform the ultraviolet lamp light expansion effect, which improves the overall curing uniformity of the LED curing device for UV printing for the paper to be cured.

[0036] In addition, when performing ultraviolet curing irradiation, the LED ultraviolet lamp 7 will generate heat, which will be transferred to each heat sink 5 through the curing irradiation box 4. Combined with the heat dissipation holes 51, effective heat conduction and rapid dissipation of the heat can be achieved, thereby increasing the service life of the LED ultraviolet lamp 7.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
