[0008] (a) Technical problems to be solved
[0009] To address the shortcomings of existing technologies, this utility model provides a rapid ink drying device for carton printing machines, solving the technical problem of ink drying during printing.
[0010] (II) Technical Solution
[0011] To achieve the above objectives, this utility model provides the following technical solution:
[0012] A rapid ink drying device for a carton printing machine, comprising:
[0013] The printing press has a corrugated paper printing mechanism in the middle, and production lines on both sides to process the ink to be printed. A drying mechanism is located above one side of the production lines to dry the printed corrugated paper.
[0014] The drying mechanism includes an outer frame and side blocks. The outer frame is a horizontal plate structure at the top, and side blocks are set around the outer perimeter of the outer frame. An organic pump is located in the middle of the outer frame, and an irradiation unit is connected to the pump via a support frame. The irradiation unit uses ultraviolet (UV) light to irradiate the ink, causing the photosensitizer to react and thus cure rapidly. A purification channel is set above the irradiation unit, forming multiple vertical upward channel structures. Combined with the channels in the irradiation unit, it achieves upward air intake at various positions. The hot air flow carries away the solvent in the ink, accelerating drying and uniformly drying the corrugated paper ink below. It can also prevent the gases generated by the irradiation unit from being used to cure the ink, as the cured ink may contain volatile organic compounds (VOCs), which can affect the environment and human health.
[0015] Preferably, a filter block is provided at the upper end of the outer frame, wherein the filter block is filled with activated carbon. Activated carbon adsorption is an economical and effective option. Activated carbon can effectively capture organic matter in waste gas and maintain its adsorption performance by periodically replacing or regenerating it. This method is suitable for intermittent emission sources, but attention should be paid to the saturation of activated carbon and the frequency of replacement.
[0016] Preferably, the irradiation unit includes an outer frame, which is a square frame structure. An inner support rod is provided in the middle of the outer frame, and several sets of ultraviolet lamps are provided in the middle of the inner support rod. The ultraviolet lamps are evenly distributed to irradiate and dry the corrugated paper placed below.
[0017] Preferably, a gap is provided between the inner support rod and the ultraviolet lamp, which, together with the suction of the pump, absorbs harmful substances in the air and introduces them into the filter block for purification before being discharged to the outside through the pipeline.
[0018] Preferably, a baffle is provided on the outer side of the side block. The baffle is a square structure plate, and three sets of lower rollers are provided below the baffle. The lower rollers are roller structures that can rotate and feed the corrugated paper above the production line to a certain extent.
[0019] Preferably, a first stop and a second stop are provided in the middle of the baffle, and several sets of hollow grooves are evenly provided in the middle of the baffle. The first stop is an L-shaped folded plate installed on the outside of the hollow groove.
[0020] Preferably, the second stop is an L-shaped folding plate installed on the outside of the first stop, and each set of the first stop, the second stop, and the hollow groove is combined into a module.
[0021] Preferably, the size and area of the first baffle are larger than that of the hollow trough, and the area of the second baffle is covered by the first baffle to prevent UV light from leaking out. This structure can achieve the exchange of external gas to maintain ventilation with the outside, and can better facilitate air circulation. Furthermore, the mutual shielding of the second baffle, the first baffle, and the hollow trough can prevent the leakage of ultraviolet light and protect the on-site environment.
[0022] (III) Beneficial Effects
[0023] 1. The printing ink is processed through an assembly line. A drying mechanism is set up on one side of the assembly line to dry the printed corrugated paper. The purification channel realizes multiple vertical upward channel structures, combined with the channels in the irradiation unit, to realize upward air suction channels at each position. The hot air flow carries away the solvent in the ink, accelerates drying, and evenly dries the ink on the corrugated paper below. It can also remove the gas generated by the irradiation unit. The cured ink may contain volatile organic compounds (VOCs), which may have an impact on the environment and human health.
[0024] 2. Several sets of ultraviolet lamps are installed in the middle of the inner support rod. The ultraviolet lamps are evenly distributed to irradiate and dry the corrugated paper placed below. In addition, there is a gap between the inner support rod and the ultraviolet lamps. Combined with the suction of the pump, harmful substances in the air are absorbed and introduced into the filter block for purification before being discharged to the outside through the pipeline.
[0025] 3. The lower roller is a roller structure that can rotate and feed the corrugated paper above the production line to a certain extent. The baffle has a first block and a second block in the middle. The first block is an L-shaped folded plate installed on the outside of the hollow trough. The second block is an L-shaped folded plate installed on the outside of the first block. Each set of the first block, the second block and the hollow trough are combined into a module. The size and area of the first block are larger than the hollow trough. The area of the second block is covered by the first block to prevent UV light leakage. This structure can realize the exchange of external gas to maintain ventilation with the outside, which can better facilitate air circulation. Furthermore, the mutual shielding of the second block, the first block and the hollow trough can prevent the leakage of ultraviolet light and protect the on-site environment.

[0035] This application provides a rapid ink drying device for a carton printing machine, which solves the problems of high efficiency and pollution prevention in ink drying in the prior art. The device uses an assembly line to process the ink to be printed. A drying mechanism is set on one side above the assembly line to dry the printed corrugated paper. The device has upward air suction channels at each position, and the hot air flow carries away the solvent in the ink, thus accelerating the drying process.
[0036] Example 1
[0037] like Figure 1-2As shown, the technical solution in this application embodiment is to solve the above-mentioned problem of efficient ink drying, and the overall idea is as follows:
[0038] To address the problems existing in the prior art, this utility model provides a rapid ink drying device for a carton printing machine, including...
[0039] The printing machine 1 has a corrugated paper printing mechanism in the middle and production lines 2 on the left and right sides of the printing machine 1. The ink to be printed is processed by the production lines 2. A drying mechanism 3 is set on one side above the production lines 2 to dry the printed corrugated paper.
[0040] like Figure 3 As shown, the drying mechanism 3 includes an outer frame 31 and side blocks 32. The outer frame 31 is a horizontal plate mechanism at the top. Side blocks 32 are arranged around the outer perimeter of the outer frame 31. An organic pump 33 is arranged in the middle of the outer frame 31. An irradiation unit 36 is connected to the bottom of the organic pump 33 via a support frame 35. The irradiation unit 36 uses ultraviolet light (UV) to irradiate the photosensitizer in the ink, thereby rapidly curing it. A purification channel 37 is arranged above the irradiation unit 36. The purification channel 37 realizes multiple sets of vertical upward channel structures. Combined with the channels in the irradiation unit 36, it realizes upward air intake channels at various positions. The hot air flow carries away the solvent in the ink, accelerates drying, and evenly dries the corrugated paper ink below. It can also remove the gas generated by the irradiation unit 36. The cured ink may contain volatile organic compounds (VOCs), which may affect the environment and human health.
[0041] The upper end of the outer frame 31 is provided with a filter block 34, which is filled with activated carbon. Activated carbon adsorption is an economical and effective option. Activated carbon can effectively capture organic matter in waste gas and maintain its adsorption performance by periodically replacing or regenerating it. This method is suitable for intermittent emission sources, but attention should be paid to the saturation of activated carbon and the frequency of replacement.
[0042] like Figure 4 As shown, the irradiation unit 36 includes an outer frame 361, which is a square frame structure. An inner support rod 362 is provided in the middle of the outer frame 361. Several sets of ultraviolet lamps 363 are arranged in the middle of the inner support rod 362. The ultraviolet lamps 363 are evenly distributed to irradiate and dry the corrugated paper placed below. In addition, there is a gap between the inner support rod 362 and the ultraviolet lamps 363. Combined with the suction of the pump 33, harmful substances in the air are absorbed and introduced into the filter block 34 for purification before being discharged to the outside through the pipeline.
[0043] Example 2
[0044] Based on Example 1, this application embodiment addresses the issue that UV light sources may emit ultraviolet radiation harmful to the environment and human body. Modern UV curing equipment is typically equipped with protective shields and safety measures. However, it is necessary to consider the pollution caused by the removal of harmful gases, ensuring ventilation while minimizing UV light leakage.

Three sets of lower rollers 322 are provided below the baffle 321. The lower rollers 322 are roller structures that can rotate and feed the corrugated paper above the production line 2 to a certain extent. A first stop 323 and a second stop 324 are provided in the middle of the baffle 321. Figure 6 and 7 As shown, the baffle 321 has several sets of hollow slots 325 evenly arranged in the middle. The first baffle 323 is an L-shaped folded plate installed on the outside of the hollow slot 325. The second baffle 324 is an L-shaped folded plate installed on the outside of the first baffle 323. Each set of the first baffle 323, the second baffle 324 and the hollow slot 325 are combined into a module. The size and area of the first baffle 323 are larger than that of the hollow slot 325. The area of the second baffle 324 covers the first baffle 323 to prevent UV light leakage. This structure can realize the exchange of external gas to maintain ventilation with the outside, and can better facilitate air circulation. Furthermore, the mutual shielding of the second baffle 324, the first baffle 323 and the hollow slot 325 can prevent the leakage of ultraviolet light and protect the on-site environment.
[0046] Replace traditional mercury vapor lamps with more energy-efficient LED UV light sources. Ensure UV curing equipment is equipped with adequate protective measures to prevent UV light leakage. Choose low-VOC or VOC-free UV inks. Properly treat and recycle waste generated during the UV curing process. Install and use UV photocatalytic decomposition equipment to reduce ozone generation.
[0047] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
