Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment technology for UV curing ovens, and in particular to a multi-layer filter structure for UV curing ovens. Background Technology

[0002] Currently, a UV curing oven is a specialized piece of equipment that uses ultraviolet (UV) radiation as an energy source to rapidly chemically polymerize UV-curable materials (such as UV coatings, UV inks, and UV adhesives) coated on the surface of a workpiece, thereby achieving material curing and molding. It is widely used in printing, electronics, plastics, building materials, medical devices and other fields, such as curing coatings on circuit boards, curing printed patterns on plastic parts, and UV adhesive bonding and curing of glass curtain walls.

[0003] Existing UV curing ovens mostly use a single-layer fixed filter structure, which has limited filtering effect and makes it difficult to adjust the filtering intensity according to actual needs. Moreover, after prolonged use, dust and impurities easily accumulate on the surface of the filter components, affecting light transmittance and filtering effect. Cleaning the filter components requires disassembling the entire filter structure, which is cumbersome and time-consuming, seriously affecting the working efficiency of the UV curing oven. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a multi-layer filter structure for UV curing ovens.

[0005] This utility model is achieved using the following technical solution: a multi-layer filter structure for a UV curing oven, comprising a support frame, a light-transmitting opening in the middle of the support frame, a multi-layer filter assembly capable of filtering light on one side of the light-transmitting opening, and a cleaning assembly capable of cleaning the multi-layer filter assembly when needed on one side of the multi-layer filter assembly. The multi-layer filter assembly includes two mounting strips fixedly installed on one side of the light-transmitting opening, multiple sliding grooves on the opposite surfaces of the two mounting strips, and multiple light-transmitting plates between the two mounting strips, with both ends of each light-transmitting plate extending into the interior of the adjacent sliding groove.

[0006] Through the above technical solution, the mounting strip provides the mounting base for the sliding groove, which can limit and guide the light-transmitting plate, making it easy to adjust the number and position of the light-transmitting plate according to the light filtering requirements. Multiple light-transmitting plates work together to achieve multi-layer light filtering, improving the flexibility and diversity of the light filtering effect.

[0007] As a further improvement to the above solution, multiple light-transmitting plates are stacked vertically.

[0008] Through the above technical solution, the vertically stacked light-transmitting panels can uniformly cover the light-transmitting opening, ensuring that light can be uniformly filtered through multiple layers of light-transmitting panels when passing through the light-transmitting opening, avoiding uneven local light filtering, and also facilitating the subsequent cleaning components to thoroughly clean each light-transmitting panel.

[0009] As a further improvement to the above solution, the cleaning component includes a mounting plate disposed on one side of the two mounting strips. The mounting plate has multiple through-holes on one side, and a cleaning plate is slidably attached to both sides of the inner wall of each cleaning hole.

[0010] Through the above technical solution, the mounting plate provides a mounting carrier for the cleaning port and the cleaning plate. The position of the cleaning port corresponds to the light-transmitting plate. The cleaning plate can slide inside the cleaning port. The light-transmitting plate is cleaned by friction between the cleaning plate and the surface of the light-transmitting plate. The cleaning operation can be completed without disassembly, which improves convenience.

[0011] As a further improvement to the above solution, a card plate is fixedly installed on the opposite side of the same end of the two mounting strips. A connecting plate is fixedly installed on both ends of the mounting plate. A slot is opened on the opposite side of the two connecting plates. Each slot is adapted to the card plate. Each card plate is located inside the adjacent slot.

[0012] Through the above technical solution, the cooperation between the card plate and the card slot can realize the quick connection and disassembly of the mounting plate and the mounting strip. When it is necessary to maintain the cleaning component or replace the cleaning plate, the mounting plate can be removed simply by detaching the card slot of the connecting plate from the card plate. The operation is simple and quick.

[0013] As a further improvement to the above solution, the mounting plate has limiting grooves at both ends near the light-transmitting plate. Each of the two limiting grooves has a limiting plate inside. Each of the two limiting plates has two limiting rods fixedly installed on one side. One end of each of the two limiting rods passes through the mounting plate and extends to its outside. Both ends of each cleaning plate pass through the inner wall of the cleaning port and extend to the adjacent limiting groove and are fixedly installed with the adjacent limiting plate.

[0014] Through the above technical solution, the limiting groove plays a limiting role for the limiting plate, preventing the limiting plate from shifting during use. The limiting rod can restrict the movement of the limiting plate within the limiting groove. When the limiting plate moves, it will drive the cleaning plate to slide within the cleaning port, realizing the simultaneous disassembly and installation of multiple cleaning plates.

[0015] As a further improvement to the above solution, both ends of the mounting plate are fixedly installed with limiting plates having movable grooves. Limiting blocks are slidably arranged inside the two limiting plates. Two limiting rods are fixedly installed on one side of each of the two limiting blocks. One end of each limiting rod passes through the limiting plate and extends to its outer side where a limiting piece is fixedly installed. A spring is sleeved on each limiting rod. The two ends of each spring abut against the limiting block and the inner wall of the movable groove, respectively. A limiting groove is opened on the side of each limiting rod near the adjacent limiting block. One side of each limiting block extends into the limiting groove of the adjacent limiting rod.

[0016] Through the above technical solution, the moving groove of the limiting plate provides moving space for the limiting block. The spring can push the limiting block into the limiting groove of the limiting rod through its own elastic force, thereby fixing the position of the limiting rod and thus fixing the position of the cleaning plate, preventing the cleaning plate from sliding at will during cleaning. When the limiting piece is pulled, the limiting piece will drive the limiting rod and the limiting block to move, causing the limiting block to disengage from the limiting groove and releasing the fixing of the limiting rod, so as to carry out the cleaning operation.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a multi-layer filter assembly design with multiple adjustable light-transmitting plates. The number of filter layers and the intensity of the filter can be adjusted according to actual needs to meet the curing requirements of different workpieces and improve the flexibility of the filter effect. The cleaning assembly can clean the light-transmitting plates without disassembling the multi-layer filter assembly. Furthermore, multiple cleaning plates can be cleaned through the limiting rod and limiting plate, improving cleaning efficiency and ensuring the light transmittance and filter effect of the light-transmitting plates.

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] Please combine Figures 1-5 This embodiment provides a multi-layer filter structure for a UV curing oven, including a support frame 1. The support frame 1 has a light-transmitting opening in the middle, and a multi-layer filter assembly capable of filtering light is provided on one side of the light-transmitting opening. A cleaning assembly capable of cleaning the multi-layer filter assembly is provided on one side of the multi-layer filter assembly when needed.

[0022] The multi-layer filter assembly includes two mounting strips 201 fixedly installed on one side of the light-transmitting opening. Multiple sliding grooves 202 are provided on the opposite surfaces of the two mounting strips 201. Multiple light-transmitting plates 203 are provided between the two mounting strips 201. Both ends of each light-transmitting plate 203 extend into the interior of the adjacent sliding groove 202. The multiple light-transmitting plates 203 are stacked vertically.

[0023] The mounting strip 201 provides a mounting base for the sliding groove 202, which can limit and guide the light-transmitting plate 203, making it easy to adjust the number and position of the light-transmitting plate 203 according to the light filtering requirements. Multiple light-transmitting plates 203 work together to achieve multi-layer light filtering, improving the flexibility and diversity of the light filtering effect.

[0024] The cleaning component includes a mounting plate 301 disposed on one side of two mounting strips 201. The mounting plate 301 has multiple through-holes 302 on one side, and a cleaning plate 303 is slidably attached to both sides of the inner wall of each cleaning hole 302.

[0025] Mounting plate 301 provides a mounting carrier for cleaning port 302 and cleaning plate 303. The position of cleaning port 302 corresponds to that of light-transmitting plate 203. Cleaning plate 303 can slide inside cleaning port 302. The light-transmitting plate 203 is cleaned by friction between cleaning plate 303 and the surface of light-transmitting plate 203. The cleaning operation can be completed without disassembly, improving convenience.

[0026] Two mounting strips 201 are fixedly mounted with a card plate 4 on opposite sides of the same end. Both ends of the mounting plate 301 are fixedly mounted with a connecting plate 5. The opposite sides of the two connecting plates 5 are provided with slots. Each slot is adapted to the card plate 4. Each card plate 4 is located inside the adjacent slot.

[0027] The cooperation between the card plate 4 and the card slot enables quick connection and disassembly of the mounting plate 301 and the mounting strip 201. When it is necessary to maintain the cleaning component or replace the cleaning plate 303, the mounting plate 301 can be removed simply by detaching the card slot of the connecting plate 5 from the card plate 4. The operation is simple and quick.

[0028] Limiting grooves are provided at both ends of the mounting plate 301 near the light-transmitting plate 203. Limiting plates 6 are provided inside the two limiting grooves. Two limiting rods 7 are fixedly installed on one side of the two limiting plates 6. One end of the two limiting rods 7 passes through the mounting plate 301 and extends to its outside. Both ends of each cleaning plate 303 pass through the inner wall of the cleaning port 302 and extend to the adjacent limiting groove and are fixedly installed with the adjacent limiting plate 6.

[0029] The limiting groove limits the limiting plate 6 to prevent it from shifting during use. The limiting rod 7 restricts the movement of the limiting plate 6 within the limiting groove. When the limiting plate 6 moves, it will cause the cleaning plate 303 to slide within the cleaning port 302, enabling the simultaneous disassembly and installation of multiple cleaning plates 303.

[0030] Both ends of the mounting plate 301 are fixedly installed with limiting plates 8 having movable grooves. Limiting blocks 9 are slidably arranged inside the two limiting plates 8. Two limiting rods 10 are fixedly installed on one side of each limiting block 9. One end of each limiting rod 10 passes through the limiting plate 8 and extends to its outer side where a limiting piece 11 is fixedly installed. A spring 12 is sleeved on each limiting rod 10. The two ends of each spring 12 abut against the limiting block 9 and the inner wall of the movable groove, respectively. Each limiting rod 7 has a limiting groove on the side near the adjacent limiting block 9. One side of each limiting block 9 extends into the limiting groove of the adjacent limiting rod 7.

[0031] The movable groove of the limiting plate 8 provides moving space for the limiting block 9. The spring 12 can push the limiting block 9 into the limiting groove of the limiting rod 7 through its own elastic force, thereby fixing the position of the limiting rod 7 and fixing the position of the cleaning plate 303 to prevent the cleaning plate 303 from sliding freely in the cleaning state. When the limiting piece 11 is pulled, the limiting piece 11 will drive the limiting rod 10 and the limiting block 9 to move, so that the limiting block 9 can be disengaged from the limiting groove and the fixing of the limiting rod 7 can be released so as to carry out the cleaning operation.

[0032] The implementation principle of a multi-layer filter structure for a UV curing oven in this application embodiment is as follows: according to the filter requirements of the workpiece processed in the UV curing oven, the number of light-transmitting plates 203 to be used is first determined, and the two ends of the corresponding number of light-transmitting plates 203 are inserted into the sliding grooves 202 of the mounting strip 201. The light-transmitting plates 203 are pushed to move along the sliding grooves 202 until the light-transmitting plates 203 cover the light-transmitting opening of the support frame 1, thus completing the filter setting.

[0033] When the surface of the light-transmitting plate 203 needs to be cleaned due to dust accumulation, the mounting plate 301 is fixed by engaging with the mounting strip 201 through the slot of the connecting plate 5, ensuring that the cleaning port 302 is aligned with the light-transmitting plate 203. The light-transmitting plate 203 in the sliding groove 202 is pushed towards the cleaning component, so that the light-transmitting plate 203 slowly slides into the cleaning port 302 of the mounting plate 301.

[0034] During this process, the two sides of the light-transmitting plate 203 will gradually come into contact with the cleaning plates 303 on both sides of the inner wall of the cleaning port 302. As the light-transmitting plate 203 continues to slide inside the cleaning port 302, the cleaning plates 303 will wipe the dust and impurities on the surface of the light-transmitting plate 203 to achieve a cleaning effect.

[0035] After the light-transmitting plate 203 has completely slid past the cleaning port 302, it is pushed in the opposite direction to return to the initial position covering the light-transmitting port along the sliding groove 202, thus completing a single cleaning operation.

[0036] If multiple cleanings are required, repeat the action of "sliding the light-transmitting plate 203 into and out of the cleaning port 302" until the surface of the light-transmitting plate 203 is clean.

[0037] When the cleaning plate 303 needs to be replaced due to wear and tear from long-term use and a decrease in cleaning effect, it can be easily disassembled and replaced by using the following parts: first, pull the limiting piece 11 on the outside of the limiting plate 8 outward. The limiting piece 11 drives the limiting rod 10 to slide outward along the moving groove of the limiting plate 8. The limiting rod 10 simultaneously drives the limiting block 9 to move. The limiting block 9 compresses the spring 12 to retract it until the limiting block 9 disengages from the limiting groove of the limiting rod 7, thus releasing the fixation of the limiting rod 7.

[0038] Next, pull the connecting plate 5 to remove the two connecting plates 5 from the clip plate 4, so that the mounting plate 301 can move.

[0039] Then, push the limiting rod 7 on the outside of the mounting plate 301. The limiting rod 7 drives the limiting plate 6 in the limiting groove to slide. The limiting plate 6 simultaneously drives the cleaning plate 303, which is fixedly connected to it, to slide along the inner wall of the cleaning port 302 until the cleaning plate 303 slides out of the cleaning port 302 completely, and then the old cleaning plate 303 can be removed.

[0040] Align the new cleaning plate 303 with the sliding path on the inner wall of the cleaning port 302, push the limiting rod 7 so that the limiting plate 6 drives the new cleaning plate 303 into the cleaning port 302 until the cleaning plate 303 is completely in contact with the inner wall of the cleaning port 302; release the limiting piece 11, and the spring 12 pushes the limiting block 9 to reset through its elastic force, and re-locks it into the limiting groove of the limiting rod 7, fixing the position of the limiting rod 7 and the limiting plate 6, thereby fixing the new cleaning plate 303 and completing the replacement.

[0041] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
