Abstract
Description
Technical Field
[0001] This utility model relates to the field of photocuring technology, and in particular to a small LED pre-curing device. Background Technology
[0002] In the printing industry, UV printing is a printing method that uses UV-curing inks to harden under the irradiation of ultraviolet lamps. However, the high-pressure mercury lamps used in traditional UV printing generate a large amount of heat while emitting ultraviolet light, shortening the lifespan of the equipment and causing shrinkage of the printed materials. Therefore, an LED-based drying and curing method has been developed. LEDs, as the light source, significantly reduce heat generation and energy consumption compared to traditional UV lamps, resulting in a longer product lifespan. However, to improve ink drying and curing efficiency, current LED curing lamps typically require multiple LEDs and surrounding cooling devices. This increases the complexity and size of the product structure, severely limiting its application scenarios and preventing its use on some smaller digital printing equipment. Utility Model Content
[0003] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to design a small LED pre-curing device, in which the water cooling channel is set vertically against the LED light board. This not only improves the drying and curing efficiency, but also simplifies the product structure and enables miniaturization, thereby increasing the application scenarios of the product.
[0004] To achieve the above objectives, this utility model provides a small LED pre-curing device, including a housing and a light source assembly and a cooling assembly connected sequentially from front to back in front of the housing. The cooling assembly includes a water-cooled plate, a left sealing block and a right sealing block respectively disposed on the left and right sides of the water-cooled plate. The water-cooled plate is fixedly connected to the housing. The water-cooled plate has interconnected water inlet channels and water outlet channels from front to back. The light source assembly is disposed close to the water-cooled plate, and the water inlet channel is located between the water outlet channel and the light source assembly.
[0005] Furthermore, the light source assembly includes: a plurality of LED beads and an LED bead holder, the LED bead holder being fixed to the front end face of the water-cooled plate, and the plurality of LED beads being horizontally arranged and fixed to the front end of the LED bead holder and facing forward.
[0006] Furthermore, the inner wall of the housing is provided with a cable routing groove, the water-cooled plate is provided with several cable routing channels, a power supply chamber is formed between the water-cooled plate and the rear wall of the housing, and the several cable routing channels pass through the water-cooled plate in the front-to-back direction.
[0007] Furthermore, the left sealing block is provided with a water inlet, a water outlet, and a power supply hole in sequence from front to back. The water inlet is connected to the water inlet channel, the water outlet is connected to the water outlet channel, and the power supply hole is connected to the power supply chamber.
[0008] Furthermore, the LED pre-curing device also includes a focusing cover, which is semi-cylindrical in shape and is fixedly connected to the LED bead holder and covers each of the LED beads.
[0009] Furthermore, the LED pre-curing device also includes a sealing plate, the left and right ends of which are fixedly connected to left and right sealing plates respectively, and the sealing plate is provided with a slot located directly in front of each of the LED beads.
[0010] The beneficial effects of adopting the above technical solution are:
[0011] The product has an interconnected water inlet channel and a water outlet channel. The water inlet channel is located close to the light source component, while the water outlet channel is located away from the light source component. This design allows the light source component to only contact the water inlet channel through which cold water is supplied. This design not only enables the product to cool down quickly and effectively improves the drying and curing efficiency, but also makes the product structure simple and miniaturized, suitable for different application scenarios.

[0016] like Figure 1-3As shown, this utility model provides a small LED pre-curing device, including a housing 1, and a light source assembly 2 and a cooling assembly 3 connected sequentially from front to back in front of the housing 1. The cooling assembly 3 includes a water-cooled plate 31, and left sealing blocks 32 and right sealing blocks 33 respectively located on the left and right sides of the water-cooled plate 31. The water-cooled plate 31 is fixedly connected to the housing 1. The water-cooled plate 31 has a water inlet channel 311 and a water outlet channel 312 connected sequentially from front to back. The light source assembly 2 is set close to the water-cooled plate 31, and the water inlet channel 311 is located between the water outlet channel 312 and the light source assembly 2. An external water supply system is connected to the water inlet channel 311 close to the light source assembly 2. The heated light source assembly 2 gradually begins to cool down under the action of the cold water. After absorbing heat, the cold water flows to the water outlet channel 312 away from the light source and flows out through the water outlet hole 323. This design structure can quickly cool the product and effectively improve the drying and curing efficiency of the product.
[0017] The light source assembly 2 includes several LED beads 21 and an LED bead holder 22. The LED bead holder 22 is fixed to the front end face of the water-cooled plate 31, and the LED beads 21 are horizontally arranged at the front end of the LED bead holder 22 and facing forward. The LED beads 21 emit light forward to cure the ink on the product, and the heat generated by the LED beads 21 and the LED bead holder 22 is transferred to the water-cooled plate 31, thereby effectively dissipating heat.
[0018] The inner wall of the casing 1 is provided with a cable tray 4, and the water-cooled plate 31 is provided with several cable routing channels 313. The water-cooled plate 31 and the rear wall of the casing 1 form a power supply chamber A. The several cable routing channels 313 run through the water-cooled plate 31 in the front-to-back direction. The several cable routing channels 313 are hidden inside the water-cooled plate 31. The cable tray 4 on the inner wall of the casing 1 can reasonably organize and store external wires, avoid the wires from getting tangled in the power supply chamber A and causing wear and tear on the wires, and also make the product more aesthetically pleasing and conducive to the miniaturization of the product.
[0019] The left sealing block 32 is provided with a water inlet 322, a water outlet 323, and a power supply hole 321 from front to back. The water inlet 322 is connected to the water inlet channel 311, the water outlet 323 is connected to the water outlet channel 312, and the power supply hole 321 is connected to the power supply chamber 43. Placing the water inlet 322, water outlet 323, and power supply hole 321 on the same end allows users to monitor both the power supply and water supply status of the product simultaneously. Furthermore, having the water supply and power supply devices on the same side optimizes the use of factory floor space and further improves productivity.
[0020] Preferably, the LED pre-curing device further includes a focusing cover 5, which is semi-cylindrical in shape. The focusing cover 5 is fixedly connected to the LED bead holder 22 and covers each LED bead 21. The semi-cylindrical focusing cover concentrates the diffused light source emitted by the LED beads, increasing the light intensity of the LED bead irradiation area and effectively improving the drying and curing efficiency of the LED lamp.
[0021] Preferably, the LED pre-curing device further includes a sealing plate 6, with its left and right ends fixedly connected to the left sealing block 32 and the right sealing block 33, respectively. The sealing plate 6 has a slot located directly in front of each LED bead 21. Since the LED beads generate a lot of heat during prolonged illumination, causing their temperature to be very high, direct contact with the beads could result in burns. The slotted sealing plate 6 covers the LED beads, ensuring that high-intensity light can be emitted through the slot while effectively solving the problem of burns caused by direct contact with the LED beads.
[0022] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
