Description

Technical Field

[0001] This utility model mainly relates to the field of laser film UV curing coating processing technology, specifically a multi-angle irradiation device for laser film UV curing coating. Background Technology

[0002] In the production of laser films, the irradiation treatment of the UV-cured coating is a key step that determines product quality.

[0003] Currently, most common UV curing irradiation devices for laser films on the market use a single-angle or fixed-angle irradiation method. That is, the radiation lamp is usually fixedly installed above or to the side of the laser film conveying path to irradiate and cure the laser film coating at a fixed angle. Due to the complex texture and uneven structure of the laser film surface, single-angle or fixed-angle irradiation can easily lead to uneven curing of the coating surface. Some areas are not fully cured due to insufficient light, while other areas suffer from coating aging and performance degradation due to excessive irradiation. Moreover, the fixed irradiation angle is difficult to adapt to the production needs of laser films with different specifications and design requirements. The equipment has poor flexibility and requires frequent replacement or adjustment of the entire irradiation component, resulting in low production efficiency and increased production costs. Utility Model Content

[0004] The purpose of this invention is to solve the problems of uneven curing of the coating on the complex texture and uneven structure of the laser film surface due to the use of a single or fixed angle irradiation method in existing devices, resulting in insufficient curing or excessive irradiation aging. At the same time, it improves the shortcomings of existing devices, such as difficulty in adapting to the production of laser films with different specifications and design requirements, poor equipment flexibility, and the need for frequent replacement and adjustment of irradiation components, which leads to low production efficiency and high cost. The proposed invention is a multi-angle irradiation device for UV curing coating of laser films.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-angle irradiation device for UV-cured laser film coatings, including:

[0007] A support box, on which an operation box is provided, and inside the support box is a conveyor capable of conveying laser film;

[0008] The support frame has a first support box at its lower end. The two ends of the first support box are hinged to second support boxes. The two second support boxes are inclined and symmetrically arranged. Radiation lamps are installed in the first support box and the two second support boxes. An adjustment mechanism is provided between the first support box and the support frame to adjust the rotation angle of the two second support boxes.

[0009] As a further description of the above technical solution, the adjustment mechanism includes a bidirectional lead screw rotatably installed in the support frame. The upper end of the first support box is provided with a connecting block fixedly connected to the support frame. The bidirectional lead screw passes through the connecting block and is rotatably connected to the connecting block. Moving blocks are threaded on both ends of the bidirectional lead screw. Fixed rods are provided on both second support boxes. A transmission rod is provided between the fixed rod and the moving block, and both ends of the transmission rod are hinged to the fixed rod and the moving block, respectively.

[0010] As a further description of the above technical solution, one end of the bidirectional lead screw passes through the support frame, and a first motor is fixedly installed on the operation box. The output end of the first motor passes through the operation box and is fixedly connected to a limit rod. A rectangular slide groove is opened in the limit rod, and a rectangular rod is slidably installed in the rectangular slide groove. The lower end of the rectangular rod and the end of the bidirectional lead screw that passes through the support frame are both fixedly connected to bevel gears, and the two bevel gears mesh with each other.

[0011] As a further description of the above technical solution, two conductive grooves are formed on the inner walls of both sides of the first support box and the two second support boxes. Two metal pins are provided at both ends of the radiant lamp tube. The metal pins slide against the conductive grooves. A second threaded rod is provided at the lower end of the metal pins of the two conductive grooves. The second threaded rod passes through the two conductive grooves and is threadedly connected to the first support box and the two second support boxes. One end of the second threaded rod passes through the outer surface of the first support box or the two second support boxes and is fixedly connected to a knob.

[0012] As a further description of the above technical solution, the support frame is provided with a threaded tube and two sleeve rods. A second motor is fixedly installed on the operation box. The output end of the second motor passes through the operation box and is fixedly connected to a first threaded rod. The first threaded rod is threadedly installed inside the threaded tube. Both ends of the inner wall of the operation box are provided with sliding rods. The lower end of the sliding rod is provided with a stop block. The sliding rod and the stop block are slidably installed inside the sleeve rod.

[0013] As a further description of the above technical solution, the operation box is equipped with a control display, which is electrically connected to the conveyor, the first motor, the second motor and the conductive trough.

[0014] As a further description of the above technical solution, a glass plate is provided on one side of the operation box.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In this invention, the two hinged second support boxes are rotated by an adjustment mechanism, so that the first support box and the radiant lamp tubes in the symmetrically tilted second support boxes form a multi-angle irradiation structure. This allows for multi-directional irradiation of complex textures and uneven structures on the surface of the laser film, significantly improving the uniformity of the UV-cured coating and avoiding performance degradation caused by insufficient curing or excessive irradiation in certain areas. At the same time, the flexible and adjustable irradiation angle eliminates the need for frequent replacement or adjustment of the entire irradiation assembly, enabling it to adapt to the production needs of laser films with different specifications and design requirements, improving equipment versatility and production efficiency, and reducing production costs.

[0024] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0025] Please refer to the appendix carefully. Figures 1-4As shown, this utility model provides a technical solution: a multi-angle irradiation device for UV curing laser film coating, including a support box 10, an operation box 11 on the support box 10, a conveyor 14 for conveying laser film inside the support box 10, a support frame 20 on the conveyor 14, a first support box 30 at the lower end of the support frame 20, and a second support box 31 hinged to both ends of the first support box 30. The two second support boxes 31 are inclined and symmetrically arranged. Radiation lamps 32 are provided inside the first support box 30 and the two second support boxes 31. An adjustable second support box 31 is provided between the first support box 30 and the support frame 20. The rotation angle adjustment mechanism drives the two hinged second support boxes 31 to rotate, so that the first support box 30 and the radiation lamp tubes 32 in the symmetrically inclined second support boxes 31 form a multi-angle irradiation structure. This can irradiate the complex texture and uneven structure of the laser film surface on the conveyor 14 in multiple directions, ensuring that the light from the radiation lamp tubes 32 acts evenly on the coating surface, improving the stability of curing quality, and reducing local curing defects caused by fixed angles. At the same time, the irradiation angle can be flexibly adjusted according to the specifications or process requirements of the laser film without replacing the entire irradiation assembly, improving the versatility of the equipment and production efficiency.

[0026] In one embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the adjustment mechanism includes a bidirectional lead screw 21 rotatably mounted within the support frame 20. The upper end of the first support box 30 is provided with a connecting block 301 fixedly connected to the support frame 20. The bidirectional lead screw 21 passes through the connecting block 301 and is rotatably connected to it. Moving blocks 22 are threaded onto the threads at both ends of the bidirectional lead screw 21. Each of the two second support boxes 31 is provided with a fixed rod 311. A transmission rod 23 is provided between the fixed rod 311 and the moving block 22, and both ends of the transmission rod 23 are hinged to the fixed rod 311 and the moving block 22, respectively.

[0027] The threads at both ends of the bidirectional lead screw 21 are arranged in opposite directions. When the bidirectional lead screw 21 rotates, the moving blocks 22 that are engaged with the threads at both ends move linearly along the axis of the lead screw. Since the threads are turned in opposite directions, the two moving blocks 22 will move closer to each other or move further away from each other in sync. When the moving blocks 22 move towards each other, the transmission rod 23 pushes the second support box 31 to rotate outward around the hinge point (the connection point with the first support box 30), increasing the irradiation angle. When the moving blocks 22 move away from each other, the transmission rod 23 pulls the second support box 31 to rotate inward, decreasing the irradiation angle.

[0028] In one embodiment of this utility model, such as Figure 2As shown, one end of the bidirectional lead screw 21 passes through the support frame 20. A first motor 26 is fixedly installed on the operation box 11. The output end of the first motor 26 passes through the operation box 11 and is fixedly connected to a limit rod 25. A rectangular slide groove 251 is provided in the limit rod 25. A rectangular rod 241 is slidably installed in the rectangular slide groove 251. The lower end of the rectangular rod 241 and the end of the bidirectional lead screw 21 that passes through the support frame 20 are both fixedly connected to bevel gears 24. The two bevel gears 24 mesh with each other.

[0029] In detail, the first motor 26 can drive the limiting rod 25 to rotate. Under the limiting of the rectangular slide groove 251 and the rectangular rod 241, it can drive the bevel gear 24 connected to the rectangular rod 241 to rotate synchronously. Under the meshing action of the two bevel gears 24, it can drive the bidirectional lead screw 21 to rotate synchronously, and further adjust the rotation angle of the two second support boxes 31 to change the irradiation angle.

[0030] In one embodiment of this utility model, such as Figure 3 As shown, two conductive grooves 33 are formed on the inner walls of both sides of the first support box 30 and the two second support boxes 31. Two metal pins 321 are provided at both ends of the radiant lamp tube 32. The metal pins 321 slide against the conductive grooves 33. A second threaded rod 34 is provided at the lower end of the metal pins 321 in the two conductive grooves 33. The second threaded rod 34 passes through the two conductive grooves 33 and is threadedly connected to the first support box 30 and the two second support boxes 31. One end of the second threaded rod 34 passes through the outer surface of the first support box 30 or the two second support boxes 31 and is fixedly connected to a knob 35. By rotating the knob 35, the second threaded rod 34 rotates in the first support box 30 or the two second support boxes 31. When the second threaded rod 34 rotates away from the conductive grooves 33, the metal pins 321 can slide freely in the conductive grooves 33, which is convenient for lamp tube disassembly or replacement. When the second threaded rod 34 rotates closer to the conductive grooves 33, the metal pins 321 are pressed together to ensure electrical contact stability.

[0031] In one embodiment of this utility model, such as Figure 2 and Figure 4 As shown, the support frame 20 is provided with a threaded tube 202 and two sleeve rods 201. The second motor 28 is fixedly installed on the operation box 11. The output end of the second motor 28 passes through the operation box 11 and is fixedly connected to the first threaded rod 27. The first threaded rod 27 is threadedly installed in the threaded tube 202. Both ends of the inner wall of the operation box 11 are provided with slide rods 111. The lower end of the slide rod 111 is provided with a stop block 112. The slide rod 111 and the stop block 112 are slidably installed in the sleeve rod 201.

[0032] The second motor 28 drives the first threaded rod 27 to rotate, which in turn drives the threaded tube 202 to rise or fall vertically, thereby adjusting the height of the radiant lamp tube 32. At the same time, the two sleeve rods 201 are fixed on the support frame 20. The slide rod 111 and the stop block 112 on the inner wall of the operating box 11 are inserted into the sleeve rods 201 to form a sliding fit. This prevents the threaded tube 202 from rotating when the first threaded rod 27 drives the threaded tube 202 to rotate, thus ensuring that the lifting process is smooth and without shaking. The stop block 112 prevents the sleeve rods 201 from falling off the slide rod 111, thus ensuring structural safety.

[0033] The control box 11 is equipped with a control display 13, which is electrically connected to the conveyor 14, the first motor 26, the second motor 28 and the conductive trough 33.

[0034] The control display 13 on the control box 11 serves as the "central control unit" of the equipment. It achieves data interaction and command transmission with the conveyor 14, the first motor 26, the second motor 28, and the conductive trough 33 through electrical connection. Its main functions are: to monitor and precisely control the laser film conveying speed of the conveyor 14, the operating status of the first motor 26 and the second motor 28 in real time, and to control the current on / off and power output of the conductive trough 33, so as to ensure the stable operation of the radiation lamp tube 32, realize the intelligent and automated operation of the entire laser film UV curing irradiation process, and improve production efficiency and process control accuracy.

[0035] In one embodiment of this utility model, such as Figure 1 As shown, a glass plate 12 is provided on one side of the operation box 11. The laser film conveying process, the working status of the radiation lamp tube 32, and the angle adjustment of the second support box 31 can be directly observed through the transparent glass plate 12, which makes it convenient for operators to check whether the equipment is operating normally and whether the irradiation position is accurate in real time.

[0036] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
