Description

Technical Field

[0001] This utility model relates to the field of printing presses, specifically to a rapid drying device for multi-color composite offset printing inks. Background Technology

[0002] In the current printing industry, in order to ensure the vibrancy of colors, multi-color composite offset printing inks are usually used for color printing. After printing, the paper usually needs to be air-dried naturally to dry the ink and ensure that the ink layer is not damaged by contact with external objects. In order to accelerate the drying speed of the ink, various drying devices are usually installed behind the printing area to dry it, such as infrared drying and ultraviolet drying.

[0003] Existing multicolor composite offset printing ink rapid drying equipment includes a UV flatbed printer consisting of a worktable, an X-axis moving block, and a sprayer. The UV flatbed printer has ultraviolet drying lamps installed on both sides of the sprayer to accelerate the drying speed of the ink.

[0004] The drying principle of UV ink involves adding photoinitiators or photosensitizers to the UV ink. These components, after absorbing the high-intensity ultraviolet light emitted by the UV lamp, generate active free radicals or cations. These active substances trigger the rapid polymerization of monomers and oligomers in the ink, forming a solid ink film. However, during prolonged use, the UV drying lamp generates a large amount of high-temperature heat. If this heat cannot be dissipated in time, it will affect the ink drying speed and increase the possibility of short circuits in the UV drying lamp. Utility Model Content

[0005] The technical problem this invention aims to solve is that the ultraviolet drying lamps used in existing multicolor composite offset printing ink rapid drying devices cannot guarantee their heat dissipation efficiency, and common fan cooling and natural cooling methods are difficult to quickly control the temperature of the ultraviolet drying lamps.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a multi-color composite offset printing ink rapid drying device, comprising a UV flatbed printer consisting of a worktable capable of Y-axis movement, an X-axis moving block for printing, and a sprayer located below the X-axis moving block. Ultraviolet drying lamps are provided on both sides of the sprayer on the X-axis moving block, and the ultraviolet drying lamps pass through the X-axis moving block.

[0007] Above the ultraviolet drying lamp is a graphene heat sink that passes through the X-axis moving block, and above the graphene heat sink are several auxiliary heat sinks. A serpentine heat dissipation pipe is provided between the partitions of the auxiliary heat sinks, and above the X-axis moving block is a pressure pump that provides circulating coolant to the serpentine heat dissipation pipe and a coolant storage tank. The graphene heat sink is connected to the cavity sidewall of the X-axis moving block by high-temperature resistant and waterproof adhesive.

[0008] As an improvement, the outer wall end of the X-axis moving block is provided with a grid window to accelerate heat dissipation.

[0009] As an improvement, the ultraviolet drying lamp is connected to the cavity sidewall of the X-axis moving block via a bolt structure.

[0010] As an improvement, the UV flatbed printer used is a Shenghuangke UV flatbed printer.

[0011] As an improvement, the ultraviolet drying lamp storage slots on both sides of the X-axis moving block are through slots, and the open end of the through slot is provided with a placement plate with a bolt structure.

[0012] As an improvement, the auxiliary heat sink is connected to the serpentine heat dissipation pipe via a U-shaped clamp.

[0013] The advantages of this invention compared to the prior art are as follows: This device rapidly transfers the heat generated by the ultraviolet drying lamp to the auxiliary heat sink above the graphene heat sink through the graphene heat sink. While the auxiliary heat sink accelerates the heat dissipation area, the serpentine heat dissipation pipes between the auxiliary heat sinks will accelerate the heat transfer, and the heat will be carried away by the coolant in the coolant storage tank, thereby ensuring the rapid cooling of the ultraviolet drying lamp.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] As per the instruction manual Figure 1 ,2 As shown in Figures 3 and 4, the multi-color composite offset ink printing machines commonly used at present typically employ a UV flatbed printer 1 consisting of a worktable 11 capable of Y-axis movement, an X-axis moving block 12 for printing, and a sprayer 13 located below the X-axis moving block 12. The UV flatbed printer 1 uses Shenghuangke UV flatbed printers, which can effectively ensure the speed of ink drying while ensuring the speed of image printing. The drying method of the UV flatbed printer 1 is ultraviolet drying, that is, ultraviolet drying lamps 14 are provided on both sides of the sprayer 13 of the X-axis moving block 12, and the ultraviolet drying lamps 14 pass through the X-axis moving block 12. While ensuring the drying speed, it is ensured that the ultraviolet drying lamps 14 will not affect the quality of spraying. The ultraviolet drying lamps 14 are fixed to the side wall inside the central cavity of the X-axis moving block 12 by screws. The center of the X-axis moving block 12 is the sprayer 13 module, and there are two through slots on both sides of the X-axis moving block 12 to store the ultraviolet drying lamps 14.

[0021] To facilitate control of the heat dissipation rate of the ultraviolet drying lamp 14, a graphene heat sink 2 passing through the X-axis moving block 12 is provided above the ultraviolet drying lamp 14, and several auxiliary heat sinks 21 are provided above the graphene heat sink 2. The graphene heat sink 2 is connected to the cavity sidewall of the X-axis moving block 12 by high-temperature resistant and waterproof adhesive. The graphene heat sink 2 is in close contact with the top wall of the ultraviolet drying lamp 14 to ensure the speed of heat conduction, and the auxiliary heat sinks 21 increase the heat dissipation area, thereby increasing the heat dissipation rate.

[0022] To accelerate the heat dissipation rate between the gaps of the auxiliary heat sink 21, a serpentine heat dissipation pipe 3 is provided between the partitions of the auxiliary heat sink 21. A pressurizing pump 4 and a coolant storage tank 5 are provided above the X-axis moving block 12 to provide circulating coolant to the serpentine heat dissipation pipe 3. The top surface of the through slots on both sides of the X-axis moving block 12 has a placement plate for placing the coolant storage tank 5. The coolant storage tank 5 and the pressurizing pump 4 are fixed to the placement plate with screws. The water-cooled heat dissipation pipe composed of the three accelerates the heat loss rate between the auxiliary heat sink 21, so that the heat dissipation of the ultraviolet drying lamp 14 can be controlled in a timely and effective manner. The auxiliary heat sink 21 is connected to the serpentine heat dissipation pipe 3 by a U-shaped clamp to ensure the heat dissipation rate of the serpentine heat dissipation pipe 3.

[0023] To facilitate the rapid dissipation of moisture on the outer wall of the serpentine heat dissipation pipe 3, a grid window 121 for accelerating heat dissipation is provided at the outer wall end of the X-axis moving block 12. While accelerating heat dissipation, it also discharges moisture from the through groove of the X-axis moving block 12, ensuring that the circuit of the ultraviolet drying lamp 14 does not become damp.

[0024] In a specific implementation of this invention, the image to be printed is input into the UV flatbed printer 1, then paper is laid on the worktable 11, and the UV flatbed printer 1 is started. During the printing process, the ink is continuously irradiated by the ultraviolet drying lamp 14. The photoinitiator or photosensitizer in the ink reacts with the ultraviolet light emitted by the ultraviolet drying lamp 14, thereby ensuring that the image can dry quickly. When the ultraviolet drying lamp 14 is started, the coolant pressurization pump 4 is started simultaneously to continuously control the temperature emitted by the ultraviolet drying lamp 14, thereby ensuring that the ultraviolet drying lamp 14 will not short-circuit due to excessive temperature.

[0025] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
