Description

Technical Field

[0001] The utility model relates to the technical field of packaging paperboard processing, in particular to a paperboard facing UV automatic coating and curing device. Background Art

[0002] As the main materials for product packaging, corrugated cardboard and packaging cardboard bear the important demands for appearance and protection during transportation and display of goods. After color printing, these cardboards usually need to undergo a series of surface treatment processes to improve their physical properties and aesthetics. Traditionally, in order to give cardboard moisture-proof and waterproof properties and protect the printed colors from fading, the commonly used method is lamination, that is, covering with a layer of plastic film. This treatment can significantly improve the durability of cardboard, especially in long-distance logistics such as sea transportation, effectively protecting products from moisture and other environmental factors.

[0003] In the prior art, UV varnish coating and curing treatment on the surface of cardboard is an effective alternative to the lamination process. UV varnish coating not only provides moisture-proof and waterproof functions similar to plastic film, but also has better environmental protection and degradability. In addition, the surface of the cardboard after UV coating will be smoother and brighter, and have better wear resistance and scratch resistance. Despite this, the existing UV varnish coating equipment has problems such as low efficiency, high equipment cost and high UV varnish consumption during operation. These problems limit the widespread application of UV coating technology, especially today when the requirements for high-speed production and automation are constantly increasing. There is an urgent need for a UV varnish coating equipment that is efficient, saves materials and reduces operating costs. Utility Model Content

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] See also Figure 1-9 A cardboard facing UV automatic coating and curing device includes an installation chassis 1 and a conveying mechanism 2, an oiling mechanism 3, and a radiation curing device 4 assembled in the installation chassis 1. The oiling mechanism 3 and the radiation curing device 4 are arranged above the conveying mechanism 2 and arranged sequentially along the transmission direction.

[0037] The oiling mechanism 3 includes a casing A31, an oiling roller 32, a homogenizing roller 33, and an oil collecting groove 34, an oil filter 35, an oil storage barrel 36, and an oil outlet pipe 37 which are connected in sequence. The oiling roller 32 and the homogenizing roller 33 are arranged side by side and rotatably installed on the casing A31. The assembly gap between the homogenizing roller 33 and the oiling roller 32 is adjustable. The oil outlet pipe 37 is installed on the casing A31 and arranged above the oiling roller 32 and the homogenizing roller 33. The oil outlet pipe 37 is provided with an oil outlet facing the oiling roller 32. Oil collecting grooves 34 are arranged on both sides of the conveying mechanism 2.

[0038] The radiation curing device 4 includes a housing B41 and multiple groups of ultraviolet light strips 42 and cooling fans 43 fixedly installed on the housing B41. The ultraviolet light strips 42 are evenly distributed above the conveying mechanism 2 and maintain multiple groups of vertical downward irradiation. The power adapter 421 matched with each ultraviolet light strip 42 is adjacently arranged with a cooling fan 43, and the directions of two adjacent groups of cooling fans 43 are kept in opposite directions.

[0039] The setting of the mounting chassis 1 can ensure that the conveying mechanism 2, the oiling mechanism 3, and the radiation curing device 4 are stably installed thereon. An assembly opening 11 connected to its inner cavity is opened on the side wall of the mounting chassis 1, which is convenient for installing various related equipment or components inside. A sealing cover plate 12 is installed on the assembly opening 11. The sealing cover plate 12 is installed by bolt fixing, which is convenient for disassembly and assembly.

[0040] Universal rollers 13 and telescopically adjustable feet 14 are also installed at the bottom corners of the installation chassis 1. When the feet 14 are in a retracted state, the universal rollers 13 are in direct contact with the ground, which facilitates the control of the transfer of the installation chassis 1. When the feet 14 are in an extended state, they are in direct contact with the ground, so that the installation chassis 1 can be stably installed in the production plant.

[0041] The top of the installation case 1 is designed to be open, so that the conveying mechanism 2 can be installed on the top. When the conveying mechanism 2 is in operation, it drives the cardboard to be coated with UV varnish from the upstream section to the downstream end, so that the cardboard can pass through the oiling mechanism 3 and the radiation curing device 4 in a stable order.

[0042] When the oiling mechanism 3 is running, the UV varnish stored in the oil storage barrel 36 is pumped to the oil outlet pipe 37, and the UV varnish is applied to the oiling roller 32 through the oil outlet opened on the oil outlet pipe 37. The oiling roller 32 usually adopts a rubber roller, which has a certain elasticity to ensure that the UV varnish thereon can be evenly applied to the upper surface of the cardboard, and the homogenizing roller 33 adopts a metal roller with a smooth surface. During the operation of the oiling roller 32 and the homogenizing roller 33, the UV varnish can be squeezed and evenly distributed to the oiling roller 32 with the help of the homogenizing roller 33. By adjusting the gap between the oiling roller 32 and the homogenizing roller 33, the thickness of the UV varnish can be achieved. During the operation of the equipment, the oiling roller 32 contacts the upper surface of the cardboard driven by the conveying mechanism 2, and then the UV varnish is evenly applied to the upper surface of the cardboard.

[0043] During the oiling process, excess UV varnish can fall into the oil collecting grooves 34 on both sides of the conveying mechanism 2, and then enter the oil filter 35 in sequence under the action of gravity and finally be collected in the oil storage barrel 36. The oil filter 35 adopts commonly used equipment on the market, which can filter the impurities (mostly cardboard scraps) carried by the UV varnish, so as to realize the recycling of excess UV varnish.

[0044] The cardboard treated by the oiling mechanism 3 is conveyed to the radiation curing device 4 by the conveying mechanism 2. An assembly frame plate 411 is fixedly connected to the inner cavity of the casing B41. An installation opening B412 is opened on the top of the casing. A cover B413 is installed at the installation opening B412 to facilitate disassembly and maintenance of the ultraviolet light strip 42 and the cooling fan 43 inside.

[0045] The ultraviolet light strip 42, the power adapter 421, and the cooling fan 43 are all fixedly mounted on the assembly frame plate 411. The ultraviolet light strip 42 adopts LED lamps, which can quickly cure UV varnish. Since the ultraviolet light strip 42 composed of the LED irradiation lamp group does not generate much heat during the irradiation process, the power adapter 421 matched with the ultraviolet light strip 42 has a low heat dissipation requirement. As a specific implementation scheme, the ultraviolet light strip 42 is arranged in two rows, and the power adapters 421 of each ultraviolet light strip 42 included in the two rows are each provided with a cooling fan 43 that blows air upward, and a cooling fan 43 that blows air downward is independently arranged between the two rows of ultraviolet light strips 42, so as to form a circulating airflow in the casing B41, so as to circulate and cool the ultraviolet light strip 42 and the matching power adapter 421. The casing B41 is a closed box without heat dissipation holes to prevent mosquitoes from entering and attaching.

[0046] In order to ensure that the conveying mechanism 2 can be stably installed on the mounting chassis 1, to ensure its stable operation to transport the cardboard to be coated with UV varnish, and to ensure that the oil collecting tank 34 is stably assembled on both sides of the conveying mechanism 2 to collect excess UV varnish, the following technical solution is provided.

[0047] The conveying mechanism 2 includes a transmission roller 21, a transmission belt 22, a No. 1 driving motor 23, and a limiting wheel 24. The transmission rollers 21 are rotatably installed at both ends of the top of the installation chassis 1. The transmission belt 22 is wound around two groups of transmission rollers 21 in a taut posture. The No. 1 driving motor 23 maintains a power connection with one group of transmission rollers 21. The limiting wheel 24 is rotatably installed inside the installation chassis 1, and the limiting wheel 24 maintains contact with both sides of the transmission belt 22. The oil collection groove 34 is arranged below the upper belt surface of the transmission belt 22.

[0048] The transmission roller 21 and the transmission belt 22 cooperate to form a belt transmission device. The No. 1 driving motor 23 is fixedly installed inside the installation chassis 1, and a No. 1 driving bevel gear 231 is fixedly connected to its output shaft. The end of one group of transmission rollers 21 is fixedly connected to a No. 1 transmission bevel gear 211 that is meshed with the No. 1 driving bevel gear 231. When the No. 1 driving motor 23 drives the transmission roller 21 to operate, the transmission belt 22 that is connected end to end can be stably transmitted in a specific direction, thereby stably transmitting the cardboard placed on the transmission belt 22.

[0049] The limiting wheels 24 are arranged at both ends of the mounting chassis 1, and limiting wheels 24 are arranged on both sides of each end. Each limiting wheel 24 is kept in contact with the side edge of the line layer belt surface of the transmission belt 22, which can effectively limit the axial invalid displacement of the transmission belt 22, so as to prevent the transmission belt 22 from running off and affecting the stability of the cardboard conveying, and also avoid the interference between the limiting wheels 24 and the conveyed cardboard. Annular limiting strips 212 can also be designed at both ends of the transmission roller 21, and the transmission belt 22 is arranged between two sets of annular limiting strips 212 to accurately limit it.

[0050] The oil collecting tank 34 is arranged below the upper transmission belt 22 , and can effectively collect excess UV varnish and transport it to the oil filter 35 .

[0051] In order to ensure that the oiling roller 32 and the homogenizing roller 33 can be stably installed in the housing A31, and to ensure that the gap between the homogenizing roller 33 and the oiling roller 32 can be adjusted while the homogenizing roller 33 rotates freely, the following technical solution is provided.

[0052] A mounting opening A311 is provided on the top of the casing A31, and a cover A312 is hingedly connected to the mounting opening A311. Mounting supports 313 are provided on both sides of the casing A31, and a sliding seat 314 is slidably mounted on the mounting supports 313. The oiling roller 32 is rotatably mounted on the mounting supports 313, and the homogenizing roller 33 is rotatably mounted on the sliding seat 314.

[0053] The oiling mechanism 3 also includes a gap adjustment component, which includes an adjusting motor 381, an adjusting screw 382, ​​and a transmission shaft 383. The adjusting motor 381 is fixedly mounted on one set of mounting supports 313 and maintains a power connection with the transmission shaft 383. The transmission shaft 383 is rotatably mounted between the two sets of mounting supports 313 and remains parallel to the homogenizing roller 33 and the oiling roller 32. The two sets of mounting supports 313 are rotatably mounted with adjusting screws 382 that are screwed to the corresponding side sliding seats 314. The two sets of adjusting screws 382 maintain a power connection with the transmission shaft 383.

[0054] In order to avoid spatial interference between the homogenizing roller 33 and the mounting support 313 , a clearance hole is opened on the side wall of the mounting support 313 to ensure that the homogenizing roller 33 is not interfered by the mounting support 313 , and the oil outlet pipe 37 is also fixedly mounted on the mounting support 313 .

[0055] The adjusting motor 381 is fixedly installed in the casing A31, and a No. 2 driving bevel gear 3811 is fixedly connected to its output shaft, a No. 2 driving bevel gear 3831 which is meshed with the No. 2 driving bevel gear 3811 is fixedly connected to the transmission shaft 383, and a No. 3 driving bevel gear 3832 which is symmetrically arranged is also fixedly connected to both ends of the transmission shaft 383, and the ends of the two sets of adjusting screws 382 are fixedly connected to a No. 3 driving bevel gear 3821 which is meshed with the No. 3 driving bevel gear 3832 on the corresponding side, and the thread spiral directions of the two sets of adjusting screws 382 are arranged in opposite directions.

[0056] When the adjustment motor 381 is running, the power can be transmitted sequentially to the two sets of adjustment screws 382 through the No. 2 driving bevel gear 3811, the No. 2 transmission bevel gear 3831, the transmission shaft 383, the No. 3 driving bevel gear 3832, and the No. 3 transmission bevel gear 3821. Since the two sets of No. 3 driving bevel gears 3832 are arranged symmetrically, the two sets of adjustment screws 382 run in opposite directions. By setting the threads of the two sets of adjustment screws 382 in opposite directions, the two sets of sliding seats 314 can be driven to maintain synchronous and stable operation at the same time, thereby driving the equalizing roller 33 mounted thereon to run stably, so as to accurately adjust the gap between the equalizing roller 33 and the oiling roller 32.

[0057] In order to ensure that the oiling roller 32 and the homogenizing roller 33 can operate in coordination and to prevent the gap adjustment component from affecting the stable operation of the homogenizing roller 33 and the oiling roller 32 when adjusting the gap between the homogenizing roller 33 and the oiling roller 32, the following technical solution is provided.

[0058] The oiling mechanism 3 also includes a driving assembly, which includes a No. 2 driving motor 391, a mounting shaft 392, a bevel gear A393, a bevel gear a394, a bevel gear B395, and a bevel gear b396. The No. 2 driving motor 391 is fixedly mounted on one of the mounting supports 313 and maintains a power connection with the oiling roller 32. The same end of the oiling roller 32 and the homogenizing roller 33 is respectively fixedly connected with a bevel gear A393 and a bevel gear B395. The mounting shaft 392 is rotatably mounted on one of the mounting supports 313, and a bevel gear a394 that meshes with the bevel gear A393 is fixedly connected to the mounting shaft 392. A bevel gear b396 that meshes with the bevel gear B395 is rotatably mounted on one of the sliding seats 314. A spline shaft 397 that maintains a sliding connection with the bevel gear b396 is fixedly connected to the mounting shaft 392.

[0059] A fourth driving bevel gear 3911 is fixedly connected to the output shaft of the second driving motor 391, and a fourth transmission bevel gear 321 meshing with the fourth driving bevel gear 3911 is fixedly connected to the oiling roller 32, so that the oiling roller 32 can be driven to operate stably when the second driving motor 391 is working.

[0060] When the oiling roller 32 is in operation, the combination of bevel gear A393 and bevel gear a394 drives the mounting shaft 392 and the spline shaft 397 to operate stably. When the gap adjustment component drives the sliding seat 314 and the homogenizing roller 33 to operate in a straight line, the bevel gear b396 thereon slides along the spline shaft 397 and can always receive the power transmitted from the mounting shaft 392, and then drives the homogenizing roller 33 to operate stably through the combination of bevel gear b396 and bevel gear B395. The bevel gear a394 and bevel gear b396 are kept symmetrically arranged, thereby realizing the reverse operation of the oiling roller 32 and the homogenizing roller 33, and then evenly coating the UV varnish attached to the oiling roller 32.

[0061] As an optimization solution, in order to facilitate the highly synchronous adjustment of the mounting bracket 313 and the components assembled thereon, so that the oiling roller 32 can effectively fit the cardboard on the transmission belt 22 for uniform coating of UV varnish, a group of electric telescopic cylinders 3131 are fixedly connected to the two groups of mounting brackets 313, and the other end of the electric telescopic cylinder 3131 is fixed in the casing A31, and the mounting bracket 313 is assembled in the casing A31 in a relatively sliding manner. Controlling the synchronous operation of the two groups of electric telescopic cylinders 3131 can drive the mounting bracket 313 and the components assembled thereon to rise and fall synchronously, so as to adjust the gap between the oiling roller 32 and the transmission belt 22.

[0062] In order to ensure that the UV varnish stored in the oil storage barrel 36 can be stably supplied to the outlet pipe and facilitate accurate regulation of the oil output of the oil outlet, the following technical solution is provided.

[0064] The oil supply pipe 361 is made of a hose material. During the process of controlling the lifting and lowering of the mounting support 313, it can ensure that the oil supply pipe 361 always remains connected with the oil outlet pipe 37 that lifts and lowers synchronously. The pressure pump 362 can transport the UV varnish stored in the oil storage barrel 36 to the oil outlet pipe 37 through the oil supply pipe 361. The electronic flow meter 364 can accurately detect the flow of the UV varnish passing through, and then adjust the flow in coordination with the opening and closing posture of the electromagnetic switch valve 363.

[0065] In order to facilitate the automated control of the conveying mechanism 2, the oiling mechanism 3, and the radiation curing device 4 so as to improve the efficiency of processing the cardboard surface, the following technical solution is provided.
