Description
Technical Field
[0001] This utility model relates to the field of shaping equipment technology, and more specifically, to a low-temperature rapid shaping equipment for PET laser film imprinting. Background Technology
[0002] In the PET laser film imprinting process, the setting stage plays a crucial role in product quality and production efficiency. To achieve good imprinting results, the laser film typically needs to be at a temperature above room temperature during imprinting. Current technology uses natural cooling for the subsequent setting process, relying primarily on natural air convection and the laser film's own thermal radiation. However, air, as a heat transfer medium, has a relatively low thermal conductivity. This results in extremely slow heat transfer from the laser film to the surrounding environment. In large-scale production, production efficiency is closely linked to the production cycle. Excessive cooling time significantly extends the entire production cycle, limiting efficiency. Therefore, we propose an improvement: a low-temperature rapid setting device for PET laser film imprinting. This device actively sets the laser film at low temperatures to improve production efficiency. Utility Model Content
[0003] The main purpose of this invention is to provide a low-temperature rapid setting device for PET laser film imprinting, which can effectively solve the problem of low cooling efficiency of existing laser films after imprinting.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A low-temperature rapid setting device for PET laser film imprinting includes a support platform. An inlet and an outlet are respectively provided on both sides of the support platform. Tension components for supporting the film material are installed on one side of the inlet and outlet, and a cooling component for reducing the temperature of the film material is installed on one side of the support platform. A mounting frame is installed on the other side of the support platform. Two auxiliary pressure rollers are rotatably mounted inside the mounting frame. The cooling component is located near the outlet, and the mounting frame is located near the inlet.
[0006] Preferably, the tension assembly includes two first supports, which are fixedly installed on both sides of the support platform. Each first support has a sliding groove inside, and a sliding seat is movably arranged inside each sliding groove. A tension roller is rotatably installed between adjacent sliding seats on both sides.
[0007] Preferably, a pressure spring is fixedly installed inside each of the sliding grooves, and one end of each pressure spring is fixedly connected to the adjacent sliding seat.
[0008] Preferably, the cooling assembly includes a second support, inside which are two sets of sealed bearings. Each set of sealed bearings is sealed to a connecting shaft. A cooling roller is provided between the two connecting shafts, and a film passes through between the two cooling rollers.
[0009] Preferably, each of the cooling rollers has a heat exchange cavity inside, and the two ends of the cooling rollers have a liquid inlet channel and a return channel, respectively.
[0010] Preferably, a partition cover is fixedly installed inside the heat exchange cavity by a connecting column, and a flow guiding channel is provided on the inner side of the partition cover. The partition cover is located between the liquid inlet channel and the return channel.
[0011] Preferably, the support platform has an installation groove on its lower side, and a water storage tank is fixedly installed inside the installation groove. The water inlet of the water storage tank is connected to a return pipe, and the water outlet of the water storage tank is connected to a branch pipe through a circulation pump. Infusion pipes are installed at both ends of the branch pipe, and a cooling fan is installed on the upper side of the water storage tank.
[0012] Preferably, the second support is provided with connecting pipes on both sides, one end of the connecting pipes on both sides is rotatably connected to the connecting shaft, and the other end of the connecting pipes on both sides is connected to the infusion pipe and the return pipe, respectively.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] (1) By setting an auxiliary pressure roller, the laser film can pass through the auxiliary pressure roller and be subjected to auxiliary pressing treatment. Through auxiliary pressing, the different layers in the laser film can be more tightly bonded. Especially for some laser film products with multi-layer structure or that need to be combined with other materials, the auxiliary pressure roller can ensure that the bonding between the layers is stronger and improve the overall quality and stability of the product.
[0015] (2) The tension component can support the laser film during the transmission process, which helps to prevent wrinkles, twists and other phenomena from occurring during the cooling and shaping process of the laser film, and ensures the performance and appearance quality of the laser film in subsequent processing and use.
[0016] (3) The laser film passes through the connecting shafts on both sides in an S-shape by means of the cooling rollers on both sides, and is attached to the surface of the cooling rollers at the bend of the laser film, so that the cooling rollers can cool the laser film. Through the cooling component, the laser film can be cooled down quickly after the printing is completed by low temperature pressing, thereby quickly fixing the microstructure and macro shape formed by the printing, realizing rapid molding and thus meeting the needs of large-scale production.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0025] like Figures 1 to 6As shown, a low-temperature rapid setting device for PET laser film embossing includes a support platform 1. An inlet 2 and an outlet 3 are respectively provided on both sides of the support platform 1. Tension components 4 for supporting the film material are installed on one side of the inlet 2 and outlet 3, and a cooling component 5 for reducing the temperature of the film material is installed on one side of the support platform 1. A mounting frame 6 is installed on the other side of the support platform 1. Two auxiliary pressure rollers 601 are rotatably mounted inside the mounting frame 6. The cooling component 5 is near the outlet 3, and the mounting frame 6 is near the inlet 2. During use, the inlet 2 is aligned with the outlet of the embossing equipment, allowing the embossed laser film to directly enter the device. The outlet 3 is aligned with subsequent processing equipment or a winding equipment, allowing the formed laser film to be directly discharged. The power for the movement of the laser film is driven by the subsequent processing equipment or the winding equipment. By winding the laser film, it passes through the cooling component 5 and the auxiliary pressure rollers 601.
[0026] The auxiliary pressure roller 601 allows the laser film to pass through and be pressed by the auxiliary pressure roller 601. The auxiliary pressing enables the different layers of the laser film to be more tightly bonded. Especially for laser film products with multi-layer structures or that need to be laminated with other materials, the auxiliary pressure roller 601 can ensure a stronger bond between the layers, thereby improving the overall quality and stability of the product.
[0027] In this embodiment, the tension assembly 4 includes two first supports 401, which are fixedly installed on both sides of the support platform 1. A sliding groove 402 is provided inside the first support 401, and a sliding seat 404 is movably arranged inside each sliding groove 402. A tension roller 405 is rotatably installed between adjacent sliding seats 404 on both sides.
[0028] Each sliding groove 402 is equipped with a pressure spring 403, and one end of each pressure spring 403 is fixedly connected to the adjacent sliding seat 404. The elastic strength of the pressure spring 403 can be replaced with pressure springs 403 of different elastic strengths as needed.
[0029] It should be noted that by adjusting the vertical installation position of the pressure spring 403 according to the height requirements of the equipment before and after this application, the tension roller 405 can support the laser film of the corresponding height. The pressure spring 403 can push the sliding seat 404 to move, thereby enabling the tension roller 405 to support the current laser film, ensuring that the surface of the laser film can be stressed and cooled evenly during subsequent forming. The tension component 4 can support the laser film during the transmission process, which helps to prevent wrinkles, twisting and other phenomena from occurring during the cooling and shaping process of the laser film, ensuring the performance and appearance quality of the laser film in subsequent processing and use.
[0030] In this embodiment, the cooling assembly 5 includes a second support 501, inside which are two sets of sealed bearings 5011. Each set of sealed bearings 5011 is sealed and connected to a connecting shaft 5034. A cooling roller 503 is arranged between the two connecting shafts 5034, and the film material passes through between the two cooling rollers 503. The cooling rollers 503 are arranged left and right, allowing the laser film to pass through the connecting shafts 5034 in an S-shape and adhere to the surface of the cooling roller 503 at the bend. This allows the cooling rollers 503 to cool the laser film, and the connecting shafts 5034 can cool both sides of the laser film separately. Through the cooling assembly 5, after the imprinting is completed, the laser film can be rapidly cooled by low-temperature pressing, thereby quickly fixing the microstructure and macroscopic shape formed by the imprinting, achieving rapid molding. It should be noted that the sealed bearings 5011 need to be inspected regularly and replaced when necessary, and the cooling rollers 503 can also be disassembled and cleaned to ensure the performance of liquid delivery.
[0031] It should be noted that the specific cooling effect on the laser film can be adjusted according to the winding speed of the external winding equipment to ensure the best cooling effect for the laser film.
[0032] In this embodiment, each cooling roller 503 has a heat exchange cavity 5031 inside, and the cooling roller 503 has a liquid inlet channel 5035 and a return channel 5033 at both ends.
[0033] The heat exchange cavity 5031 is fixedly provided with a partition cover 5032 by a connecting column 5036. A flow guide channel 5037 is provided on the inner side of the partition cover 5032. The partition cover 5032 is located between the liquid inlet channel 5035 and the return channel 5033.
[0034] Coolant is received through one side connecting pipe 5012 and then enters the inlet channel 5035. The liquid then exchanges heat with the external laser film through the outer heat exchange cavity 5031, achieving low-temperature cooling and shaping of the laser film. Subsequently, guided by the separator 5032 and the guide channel 5037, the heat-exchanged liquid is concentrated in the return channel 5033 and finally discharged from the other side connecting pipe 5012. Through the above structure, the cooling roller 503 can achieve continuous low-temperature heat exchange operation, thereby ensuring that all laser films passing through it receive low-temperature treatment. Furthermore, through the rotational cooperation of the sealed bearing 5011 and the connecting shaft 5034, the cooling roller 503 can passively rotate in conjunction with the winding of the laser film, thereby bringing other low-temperature surfaces of the cooling roller 503 into contact with the laser film, thus improving the low-temperature treatment effect.
[0035] In this embodiment, an installation groove 7 is provided on the lower side of the support platform 1. A water storage tank 502 is fixedly installed inside the installation groove 7. The inlet of the water storage tank 502 is connected to a return pipe 5025. The outlet of the water storage tank 502 is connected to a branch pipe 5022 through a circulation pump 5021. Infusion pipes 5023 are installed at both ends of the branch pipe 5022. A cooling fan 5024 is provided on the upper side of the water storage tank 502.
[0036] Among them, the second support 501 is provided with connecting pipes 5012 on both sides. One end of the connecting pipes 5012 on both sides is rotatably connected to the connecting shaft 5034, and the other end of the connecting pipes 5012 on both sides is connected to the infusion pipe 5023 and the return pipe 5025 respectively.
[0037] The connection between the inlet channel 5035 and the return channel 5033 enables the circulation pump 5021 to be started, allowing the low-temperature liquid inside the lower part of the water tank 502 to enter the branch pipe 5022 and finally connect to the inlet channel 5035 through the delivery pipe 5023. After heat exchange, the liquid is discharged to the upper part of the water tank 502 through the return pipe 5025. The cooling fan 5024 can lower the water temperature inside the water tank 502. The above structure can achieve a continuous supply of low-temperature liquid to meet the continuous cooling needs in conjunction with the cooling roller 503.
[0038] The working principle of a low-temperature rapid setting device for PET laser film imprinting:
[0039] In use, the circulating pump 5021 is first started to draw the low-temperature liquid from the lower part of the water tank 502 into the inlet channel 5035 through the branch pipe 5022, the delivery pipe 5023, and the connecting pipe 5012. Then, through the continuous delivery of coolant, the liquid can exchange heat with the external laser film through the heat exchange cavity 5031 on the outside, so as to achieve low-temperature cooling and shaping of the laser film. After the heat exchange is completed, the liquid passes through the guide channel 5037, the return channel 5033, the connecting pipe 5012 on the other side, and the return pipe 5025 in sequence, and finally flows back into the water tank 502 to achieve circulating cooling.
[0040] The movement of the laser film is achieved by the subsequent winding equipment, which allows the laser film to actively pass through the cooling rollers 503 on both sides, thus achieving continuous low-temperature shaping.
[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
