Description

Technical Field

[0001] This utility model relates to the field of UV curing equipment technology, specifically a dual-head alternating UV curing unit. Background Technology

[0002] UV curing equipment is a device that uses ultraviolet light to rapidly cure UV coatings, inks, and other materials. It consists of a UV light source, a reflector, and a conveying system. It is widely used in industries such as printing, electronics, and building materials. It features fast curing speed, low energy consumption, and environmental friendliness. It can improve production efficiency and reduce volatile emissions. By using UV lamps of different power and wavelength, it can be adapted to a variety of materials, making it a highly efficient surface treatment device in modern industry.

[0003] UV curing equipment is widely used, but it still has some problems: 1) Traditional single-lamp UV curing machines accumulate heat due to continuous operation, requiring frequent shutdowns for cooling, which leads to production line efficiency loss; 2) Although dual-station equipment can operate alternately, it requires an independent cooling system, which doubles the cost and occupies a large space. Therefore, in view of the above situation, it is urgent to develop a dual-head alternating UV curing unit to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a dual-head alternating UV curing unit to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-head alternating UV curing unit, comprising a cabinet, a base, a curing mechanism, and a driving mechanism; the base is fixedly disposed at the center of the upper surface of the cabinet, the curing mechanism is installed on the base, the driving mechanism is installed inside the base, and the curing mechanism and the driving mechanism are connected in a driving connection.

[0006] The curing mechanism includes a mounting base and alternating lamp groups. The mounting base is fixed on the base, and several sets of alternating lamp groups are radially distributed around the center of the mounting base and are rotatably connected to the mounting base. The alternating lamp groups include a shaft seat, a flip seat, an inner shaft, a lamp holder, and a UV lamp. The shaft seat is horizontally inserted through the side wall of the mounting base and is fixedly connected to the mounting base. The inner shaft is inserted inside the shaft seat and is rotatably connected to the shaft seat. The flip seat is fixed at the end of the inner shaft located outside the mounting base. The lamp holder and the UV lamp are a set, and there are two sets in total. The two sets of UV lamps are mounted opposite each other on the upper and lower surfaces of the flip seat through the lamp holder.

[0007] Specifically, through the radially distributed alternating lamp groups and their double lamp holder flipping structure in the curing mechanism, combined with the drive mechanism driving the inner shaft to rotate the flipping seat, the automatic alternating operation of two sets of UV lamps at the same workstation is realized. Relying on the unified cooling system integrated with the cabinet and base, the UV lamps in the non-working state are continuously cooled, which effectively solves the problem of UV lamps needing to be stopped for cooling due to overheating in continuous production lines, significantly extends the service life of UV lamps and ensures uninterrupted operation of the production process.

[0008] Preferably, the upper surface edge of the cabinet has several processing positions arranged radially around the center, and each processing position corresponds to and is vertically aligned with an alternating light group.

[0009] Specifically, by setting processing positions that correspond one-to-one with and are vertically aligned with the radial alternating light groups on the upper surface edge of the cabinet, the dual UV lamp structure of each alternating light group can precisely cover the dedicated work station.

[0010] Preferably, the lamp holder also includes a bevel gear a, a heat insulation pad, a water-cooling jacket, and a heat dissipation liner. The bevel gear a is installed at one end of the inner shaft located in the mounting base. The heat insulation pad is embedded between the lamp holder and the flip base. The heat dissipation liner and the water-cooling jacket are fitted onto the UV lamp. The heat dissipation liner is embedded in the water-cooling jacket and fits tightly with it. The interior of both the water-cooling jacket and the heat dissipation liner has mutually compatible internal flow channels.

[0011] Specifically, by adding bevel gear a, heat insulation pad, water-cooling jacket, and heat dissipation liner to the alternating lamp assembly, the equipment performance is further optimized. Bevel gear a, installed at one end of the inner shaft within the mounting base, can cooperate with the drive mechanism to achieve precise transmission of the inner shaft, ensuring stable alternating operation of the two UV lamps driven by the tilting base. The heat insulation pad, embedded between the lamp holder and the tilting base, effectively prevents the heat generated by the UV lamps during operation from being transferred to the tilting base and other components, avoiding high temperatures affecting the equipment's lifespan and operational stability. The heat dissipation liner and water-cooling jacket, fitted onto the UV lamps, form a highly efficient heat dissipation system through the tightly fitted structure of the heat dissipation liner embedded within the water-cooling jacket, combined with their mutually compatible internal flow channels. This significantly improves the heat dissipation efficiency of the UV lamps. Combined with the alternating operation design of the dual lamp assemblies, and with the stable support of the cabinet and base, this ensures that each processing station continuously receives high-quality UV curing treatment, further extends the lifespan of the UV lamps, reduces equipment maintenance frequency, and improves overall production efficiency.

[0012] Preferably, a single bearing seat has two diversion valves installed on its side, and the ends of the diversion valves have two ports a for inlet and outlet of coolant. The outer wall of the water jacket has two ports b for inlet and outlet of coolant, and ports a and b are connected by a hose.

[0013] Specifically, the two diversion valves installed on the side of a single shaft seat have two ports a at their ends connected to two ports b on the outer wall of the water-cooling jacket via hoses, forming a precise coolant circulation path. This design allows the coolant in the same cooling system to be orderly distributed to the water-cooling jackets of each set of alternating lamps through the diversion valves. Combined with the internal flow channels that are compatible with the water-cooling jacket and the heat dissipation lining, the heat dissipation efficiency of the UV lamps is greatly improved. At the same time, the bevel gear a ensures that the inner shaft drives the flip-up seat to rotate stably to realize the two sets of UV lamps.

[0014] Preferably, the inner shaft is hollow inside, the middle section of the flip seat is hollow, and the edge of the flip seat is fitted with a side cover.

[0015] Specifically, the hollow interior of the inner shaft can be used to run power supply lines, preventing the lines from being exposed to high temperatures or mechanical movements. At the same time, the hollowed-out middle section of the flip seat reduces the structural weight and heat conduction. Combined with the side cover to seal and protect the edges of the flip seat, it can prevent dust and other impurities from entering and affecting the internal components.

[0016] Preferably, the drive mechanism includes a servo motor, a bevel gear b, and a mounting bracket. The servo motor is fixed in the base via the mounting bracket, the bevel gear b is driven by the servo motor, and several bevel gears a mesh with the bevel gear b.

[0017] Specifically, the drive mechanism securely mounts the servo motor in the base via a mounting bracket. The bevel gear b connected to the servo motor meshes with several bevel gears a to form a precise transmission system. This design utilizes the characteristics of bevel gear meshing transmission to efficiently transmit the power of the servo motor to each inner shaft, causing the flipping base to rotate synchronously, ensuring that the two sets of UV lamps mounted on the lamp holders in the alternating lamp group can achieve precise alternating operation.

[0018] Preferably, the upper surface of the mounting base is fitted with a top cover for sealing.

[0019] Compared with the prior art, this utility model provides a dual-head alternating UV curing unit, which has the following beneficial effects:

[0020] By having each processing station on the cabinet correspond to an alternating set of UV lamps, and using a servo motor in the drive mechanism to drive a bevel gear meshing transmission, the rotating seat drives the upper and lower sets of UV lamps to work alternately. This avoids the heat accumulation problem caused by continuous operation of a single lamp set, eliminating the need for frequent shutdowns for cooling and ensuring production line efficiency. Furthermore, by sharing the same cooling system, and utilizing the efficient heat dissipation pathway formed by the diversion valve, water cooling jacket, and heat dissipation lining, the independent cooling system of dual-station equipment is eliminated, reducing costs and space occupation. At the same time, the hollow inner shaft and the hollow design of the rotating seat optimize the wiring layout and heat dissipation, thus improving the overall economy, space utilization, and operational stability of the equipment.

[0035] Example:

[0036] Please see Figures 1-10 This utility model provides a technical solution: a dual-head alternating UV curing unit, including a cabinet 10, a base 20, a curing mechanism 30 and a driving mechanism 40; the base 20 is fixed at the center of the upper surface of the cabinet 10, the curing mechanism 30 is installed on the base 20, the driving mechanism 40 is installed inside the base 20, and the curing mechanism 30 and the driving mechanism 40 are drivenly connected.

[0037] The curing mechanism 30 includes a mounting base 310 and alternating lamp groups 320. The mounting base 310 is fixed on the base 20. Several sets of alternating lamp groups 320 are radially distributed around the center of the mounting base 310 and are rotatably connected to the mounting base 310. The alternating lamp group 320 includes a bearing 321, a flipping base 322, an inner shaft 323, a lamp holder 326, and a UV lamp 329. The bearing 321 is horizontally inserted through the side wall of the mounting base 310 and is fixedly connected to the mounting base 310. The inner shaft 323 is inserted inside the bearing 321 and is rotatably connected to the bearing 321. The flipping base 322 is fixed at the end of the inner shaft 323 located outside the mounting base 310. The lamp holder 326 and the UV lamp 329 are a group, and there are two groups in total. The two groups of UV lamps 329 are mounted opposite each other on the upper and lower surfaces of the flipping base 322 through the lamp holder 326.

[0038] Specifically, through the radially distributed alternating lamp groups 320 and their double lamp holder flipping structure in the curing mechanism 30, combined with the drive mechanism 40 driving the inner shaft 323 to rotate the flipping seat 322, the automatic alternating operation of two sets of UV lamps 329 at the same workstation is realized. Relying on the unified cooling system integrated by the cabinet 10 and the base 20, the UV lamps 329 in the non-working state are continuously cooled, which effectively solves the problem of UV lamps 329 needing to stop for cooling due to overheating in continuous production lines, significantly extends the service life of UV lamps 329 and ensures uninterrupted operation of the production process.

[0039] Preferably, a number of processing positions 110 are installed on the upper surface edge of the cabinet 10 in a radial pattern around the center. The processing positions 110 correspond one-to-one with the alternating light groups 320 and are vertically aligned.

[0040] Specifically, by setting processing positions 110 on the upper surface edge of the cabinet 10 that correspond one-to-one with and are vertically aligned with the radial alternating light groups 320, the dual UV lamp 329 structure of each alternating light group 320 can precisely cover the dedicated work station.

[0041] Preferably, the lamp holder 326 further includes a bevel gear a324, a heat insulation pad 325, a water-cooling jacket 327, and a heat dissipation liner 328. The bevel gear a324 is installed at one end of the inner shaft 323 located in the mounting base 310. The heat insulation pad 325 is embedded between the lamp holder 326 and the flip base 322. The heat dissipation liner 328 and the water-cooling jacket 327 are fitted onto the UV lamp 329. The heat dissipation liner 328 is embedded in the water-cooling jacket 327 and fits tightly with the heat dissipation liner 328. The interior of the water-cooling jacket 327 and the heat dissipation liner 328 are both provided with mutually compatible internal flow channels 3271.

[0042] Specifically, by adding a bevel gear a324, a heat insulation pad 325, a water-cooling jacket 327, and a heat dissipation liner 328 to the alternating lamp assembly 320, the equipment performance is further optimized. The bevel gear a324 is installed at one end of the inner shaft 323 within the mounting base 310, and can cooperate with the drive mechanism 40 to achieve precise transmission of the inner shaft 323, ensuring that the flipping base 322 drives the two sets of UV lamps 329 to operate stably and alternately. The heat insulation pad 325 is embedded between the lamp holder 326 and the flipping base 322, effectively preventing the heat generated by the UV lamps 329 during operation from being transferred to the flipping base 322 and other components, avoiding high temperatures affecting the equipment's lifespan and operational stability. The heat dissipation liner 328 and the water-cooling jacket 327, fitted onto the UV lamps 329, form a highly efficient heat dissipation system through the tightly fitted structure of the heat dissipation liner 328 embedded within the water-cooling jacket 327, combined with their mutually compatible internal flow channels 3271, significantly improving the UV lamp's cooling performance. The heat dissipation efficiency of lamp 329, combined with the alternating operation design of dual lamp groups, and the stable support of cabinet 10 and base 20, can ensure that each processing station 110 continuously receives high-quality UV curing treatment, further extend the service life of UV lamp 329, reduce equipment maintenance frequency, and improve overall production efficiency.

[0043] Preferably, a single bearing 321 has two diversion valves 3211 mounted on its side. The ends of the diversion valves 3211 are equipped with two ports a3212 for inlet and outlet of coolant. The outer wall of the water cooling jacket 327 is equipped with two ports b3272 for inlet and outlet of coolant. Ports a3212 and b3272 are connected by a hose.

[0044] Specifically, the two diversion valves 3211 mounted on the side of a single shaft seat 321 have two ports a3212 at their ends connected to two ports b3272 on the outer wall of the water cooling jacket 327 via hoses, forming a precise coolant circulation path. This design allows the coolant of the same cooling system to be orderly distributed to the water cooling jackets 327 of each group of alternating lamps 320 through the diversion valves 3211. Combined with the internal flow channels 3271 that are compatible between the water cooling jacket 327 and the heat dissipation liner 328, the heat dissipation efficiency of the UV lamps 329 is greatly improved. At the same time, the bevel gear a324 ensures that the inner shaft 323 drives the flip seat 322 to rotate stably to realize the two groups of UV lamps 329.

[0045] Preferably, the inner shaft 323 is hollow inside, the middle section of the flip seat 322 is hollow, and the edge of the flip seat 322 is fitted with a side cover 3221.

[0046] Specifically, the hollow interior of the inner shaft 323 can be used to run power supply lines, preventing the lines from being exposed to high temperatures or mechanical movements. Meanwhile, the hollowed-out middle section of the flip seat 322 reduces the structural weight and heat conduction. Combined with the side cover 3221 that seals and protects the edges of the flip seat 322, it can prevent dust and other impurities from entering and affecting the internal components.

[0047] Preferably, the drive mechanism 40 includes a servo motor 410, a bevel gear b420 and a mounting bracket 430. The servo motor 410 is fixed in the base 20 through the mounting bracket 430. The bevel gear b420 is driven by the servo motor 410, and a plurality of bevel gears a324 mesh with the bevel gear b420.

[0048] Specifically, the drive mechanism 40 securely mounts the servo motor 410 within the base 20 via the mounting bracket 430. The bevel gear b420 connected to the servo motor 410 meshes with several bevel gears a324 to form a precise transmission system. This design utilizes the characteristics of bevel gear meshing transmission to efficiently transmit the power of the servo motor 410 to each inner shaft 323, causing the flipping seat 322 to rotate synchronously, ensuring that the two sets of UV lamps 329 mounted through the lamp holder 326 in the alternating lamp group 320 can achieve precise alternating operation.

[0049] Preferably, a top cover 330 for sealing is mounted on the upper surface of the mounting base 310.

[0050] Working principle: The bevel gear b420 driven by the servo motor 410 meshes with the bevel gear a324 of several alternating lamp groups 320, providing rotational power to the inner shaft 323. When the inner shaft 323 rotates within the bearing seat 321, it drives the flipping seat 322 to flip, so that the upper and lower surfaces of the flipping seat 322 are alternately aligned with the corresponding processing positions 110 on the cabinet 10 through the two sets of UV lamps 329 mounted on the lamp holder 326, realizing single-station dual-lamp group alternating operation. During operation, the power supply line running through the hollow structure inside the inner shaft 323 provides stable power to the UV lamps 329. The hollow design of the flipping seat 322, together with the side cover 3221, protects the internal components. At the same time, the same cooling system is connected to the interface b3272 of the water cooling jacket 327 through the diversion valve 3211 and interface a3212 on the bearing seat 321. The coolant dissipates heat from the UV lamps 329 through the inner flow channel 3271 and the heat dissipation liner 328. The heat insulation pad 325 blocks heat transfer, ultimately realizing UV... The lamp 329 is cooled without stopping, ensuring continuous operation of the production line. It should be noted that the input and output ends of the diversion valve 3211 are connected to the liquid cooling system, which can be installed inside the cabinet 10. The alternating lamp group 320 adopts a 180-degree reciprocating flipping method, which uses a forward and reverse alternation method. Therefore, there is no need to use an electric slip ring structure, and the liquid cooling hose will not entangle.

[0051] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
