Abstract
Description
Technical Field
[0001] This utility model relates to the field of UV curing technology, specifically a UV curing device for processing sheet materials. Background Technology
[0002] A UV curing machine is a device that uses a UV light source to cure UV coatings. Ultraviolet light irradiation causes a chemical reaction in the photoinitiator of a specially formulated resin, initiating a polymerization reaction that transforms the coating from a liquid to a solid state within seconds. After applying UV coating to a wood panel, UV irradiation triggers a chemical reaction in the photoinitiator within the coating, causing it to cure rapidly and form a dense protective film. This film not only increases the hardness of the wood panel but also improves its waterproof, stain-resistant, and wear-resistant properties.
[0003] In summary, to enhance the durability, scratch resistance, appearance, and environmental safety of wood panels, many manufacturers choose to add a UV coating to their surfaces. This not only extends the lifespan of the wood panels but also improves their aesthetics and practicality.
[0004] Existing UV curing devices for sheet processing are not convenient for limiting and rolling different specifications of sheets during the UV curing process, and are not convenient for simultaneously performing UV curing processing on both sides of different specifications of sheets. Therefore, this utility model provides a UV curing device for sheet processing. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a UV curing device for sheet material processing, which solves the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a UV curing device for sheet processing, comprising an operating table, conveying rollers rotatably connected between the front and rear sides of the inner wall of the operating table, a sheet conveyor belt drivingly connected between the two conveying rollers, a conveyor motor fixedly connected to the front side wall of the operating table, a UV curing chamber fixedly connected to the top of the operating table, sheet inlets and outlets opened on the front and rear sides of the UV curing chamber, a fixing plate fixedly connected above the sheet inlets and outlets on the front and rear sides of the UV curing chamber, and an electric push rod fixedly connected to the top of the fixing plate. A first roller fixing frame is fixedly connected to the bottom of the device. A first plate limiting roller is rotatably connected to the inner wall of the first roller fixing frame via a bearing. Servo motors are fixedly connected to both sides of the top of the operating table. One-way screws are fixedly connected to the output ends of the two servo motors. A limiting lifting and moving frame is threaded onto the surface of the one-way screw. An ultraviolet lamp is fixedly connected to the inner side wall of the limiting lifting and moving frame. A return spring is fixedly connected to the inner top wall of the UV curing chamber. A second roller fixing frame is fixedly connected to the bottom of the return spring. A second plate limiting roller is rotatably connected to the inner wall bearing of the second roller fixing frame.
[0007] Preferably, the surface of the sheet conveyor belt is provided with a plurality of silicone anti-slip particles.
[0008] Preferably, there are two electric push rods, and the two electric push rods are externally connected to a synchronous starter.
[0009] Preferably, the number of servo motors is two, and the two servo motors are externally connected to a linkage controller.
[0010] Preferably, the inner wall of the operating table is provided with limit slide grooves on both sides, and the limit lifting and moving frame is movably connected to the limit slide grooves.
[0011] Preferably, both the surface of the first plate limiting roller and the second plate limiting roller are fixedly connected with silicone anti-slip pads, and the bottom of the silicone anti-slip pads is rotatably connected to the plate body.
[0012] Compared with the prior art, this utility model provides a UV curing device for sheet processing, which has the following beneficial effects:
[0013] This UV curing device for sheet processing is designed with a coordinated setup of an operating table, conveyor rollers, a sheet conveyor belt, a conveyor motor, a UV curing chamber, and sheet inlets / outlets. During operation, the sheets are placed in the middle of the conveyor belt and sequentially transported through the inlets / outlets, serving as the material feeder for the UV curing process. The device also includes a fixed plate, electric push rods, a first roller shaft fixing frame, a first sheet limiting roller shaft, a return spring, a second roller shaft fixing frame, a second sheet limiting roller shaft, and silicone anti-slip pads. During operation, two electric push rods, driven by a synchronous starter, simultaneously move the first roller shaft fixing frame and the first sheet limiting roller shaft downwards until the silicone anti-slip pads adhere to the top of the sheets of different specifications for rolling and limiting. The sheets of different specifications are then conveyed to the surface of the second sheet limiting roller shaft. Beneath the silicone anti-slip pad, the return spring is compressed, allowing both sides of different sized boards to undergo UV curing simultaneously. This serves as a limiting rolling mechanism for different sized boards during UV curing, facilitating simultaneous UV curing of both sides and improving efficiency. The system utilizes a combination of servo motors, a one-way screw, a limiting lifting frame, and a UV lamp. During operation, two servo motors connected to an external power supply drive the one-way screw to rotate left and right via a linkage controller. This causes the limiting lifting frame to move the UV lamp threadedly on the one-way screw surface up and down to a suitable height for irradiation and curing. This allows for adjustment of the UV curing height as needed. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-2This utility model provides a technical solution: a UV curing device for sheet processing, including an operating table 1. The device is configured with the operating table 1, conveyor rollers 2, a sheet conveyor belt 3, a conveyor motor 4, a UV curing chamber 5, and sheet inlet / outlet 6. During use, the sheet is placed in the middle of the sheet conveyor belt 3 and conveyed sequentially through the sheet inlet / outlet 6, thus feeding the sheet during the UV curing process. Conveyor rollers 2 are rotatably connected between the front and rear sides of the inner wall of the operating table 1, and the sheet conveyor belt 3 is driven between the two conveyor rollers 2. A conveyor motor 4 is fixedly connected to the front side wall of the operating table 1, and a UV curing chamber 5 is fixedly connected to the top of the operating table 1. Sheet plates are provided on the front and rear sides of the UV curing chamber 5. The inlet / outlet 6 and the UV curing chamber 5 are both fixedly connected to the top of the inlet / outlet 6 on both sides of the panels. Through the coordinated arrangement of the fixed plates 7, electric push rods 8, first roller shaft fixing frame 9, first panel limiting roller shaft 10, return spring 15, second roller shaft fixing frame 16, second panel limiting roller shaft 17, and silicone anti-slip pads 18, in use, the two electric push rods 8 synchronously drive the first roller shaft fixing frame 9 and the first panel limiting roller shaft 10 downwards until the silicone anti-slip pads 18 adhere to the top of panels of different specifications for rolling and limiting. Then, panels of different specifications are conveyed to the surface of the second panel limiting roller shaft 17 below the silicone anti-slip pads 18. At this time, the return spring 15 is compressed, causing the panels of different specifications to be rotated in opposite directions. Both sides can be UV-cured simultaneously, thus serving as a limiting rolling and moving mechanism for boards of different specifications during the UV curing process. This facilitates simultaneous UV curing of both sides of boards of different specifications, improving the efficiency of UV curing. An electric push rod 8 is fixedly connected to the top of the fixed plate 7, and a first roller shaft fixing frame 9 is fixedly connected to the bottom of the electric push rod 8. The inner wall of the first roller shaft fixing frame 9 is rotatably connected to the first board limiting roller shaft 10 via bearings. Servo motors 11 are fixedly connected to both sides of the top of the operating table 1. Through the coordinated arrangement of the servo motors 11, one-way screws 12, limiting lifting and moving frame 13, and ultraviolet lamps 14, the two servo motors 11 are connected to an external power supply and linked for control during use. The controller synchronously drives the unidirectional screw 12 to rotate left and right, causing the limiting lifting and moving frame 13 to move up and down on the surface of the unidirectional screw 12 to a suitable height for irradiation and curing. This allows for adjustment of the UV curing height of the UV lamp 14 as needed. The output ends of the two servo motors 11 are fixedly connected to the unidirectional screw 12. The surface of the unidirectional screw 12 is threadedly connected to the limiting lifting and moving frame 13. The UV lamp 14 is fixedly connected to the inner wall of the limiting lifting and moving frame 13. A return spring 15 is fixedly connected to the inner top wall of the UV curing chamber 5. A second roller shaft fixing frame 16 is fixedly connected to the bottom of the return spring 15. The second plate limiting roller shaft 17 is rotatably connected to the bearing on the inner wall of the second roller shaft fixing frame 16.The surface of the sheet conveyor belt 3 is covered with several silicone anti-slip particles. There are two electric push rods 8, each connected to a synchronous starter. There are two servo motors 11, each connected to a linkage controller. Limit grooves are provided on both sides of the inner wall of the operating platform 1. A limit lifting and moving frame 13 is movably connected to the limit grooves. Silicone anti-slip pads 18 are fixedly connected to the surfaces of the first sheet limit roller 10 and the second sheet limit roller 17. The bottom of the silicone anti-slip pads 18 is rolledly connected to the sheet body.
[0019] In summary, this UV curing device for sheet processing, through the coordinated arrangement of the operating table 1, conveying roller 2, sheet conveying belt 3, conveying motor 4, UV curing chamber 5, and sheet inlet / outlet 6, allows the sheet to be placed in the middle of the sheet conveying belt 3 and conveyed sequentially through the sheet inlet / outlet 6, thus serving as the material feeder for the sheet during the UV curing process. Through the coordinated arrangement of the fixing plate 7, electric push rod 8, first roller shaft fixing frame 9, first sheet limiting roller shaft 10, return spring 15, second roller shaft fixing frame 16, second sheet limiting roller shaft 17, and silicone anti-slip pad 18, during operation, the two electric push rods 8 synchronously drive the first roller shaft fixing frame 9 and the first sheet limiting roller shaft 10 downwards until the silicone anti-slip pad 18 adheres to the top of the sheet of different specifications for rolling and limiting, thereby conveying the sheet of different specifications to the second sheet limiting roller. Below the silicone anti-slip pad 18 on the surface of shaft 17, the return spring 15 is compressed, allowing the front and back sides of different sized boards to be UV-cured simultaneously. This serves to limit the movement of different sized boards during the UV curing process, facilitating simultaneous UV curing of both sides of different sized boards and improving the efficiency of UV curing. Through the coordinated setup of servo motor 11, one-way screw 12, limit lifting frame 13, and ultraviolet lamp 14, the two servo motors 11 are connected to an external power supply and synchronously drive the one-way screw 12 to rotate left and right through the linkage controller. This causes the limit lifting frame 13 to move the ultraviolet lamp 14 up and down on the surface of the one-way screw 12 to a suitable height for irradiation and curing, thus allowing the height of the ultraviolet lamp 14 to be irradiated and cured as needed.
