Description

Technical Field

[0001] This utility model relates to the field of printing cooling technology, and more specifically, to a laser film printing cooling and shaping device. Background Technology

[0002] During the laser film printing process, the printed laser film needs to undergo a cooling and setting process to ensure the stability of the film pattern and avoid shrinkage, deformation, or blurring of the pattern due to excessive temperature.

[0003] Patent CN204820651U discloses a rapid cooling and shaping device for printed materials, including a frame, a fan, and several shaping isolation plates. The fan is positioned below the surface of the frame and connected to the frame surface via a flared air outlet. The shaping isolation plates are arranged vertically at intervals on the frame surface, each having an arc-shaped shaping surface. The fan directs air from the bottom of the frame into the intervals between the shaping isolation plates. This invention allows for rapid air cooling of printed materials, and during the cooling process, the shaping isolation plates restore the shape, resulting in flat printed materials that are easier to process later.

[0004] Existing technologies employ a single blowing structure, which presents the following problems: uneven airflow distribution on the film surface, resulting in a large temperature difference between the film edge and the center area, and limited heat exchange efficiency between the cold air and the film surface. Especially for thicker laser films or those with thicker ink layers, surface airflow alone is insufficient to quickly remove internal heat, leading to prolonged cooling time and making it unsuitable for the high-speed operation of modern printing production lines. Utility Model Content

[0005] The main objective of this invention is to provide a laser film printing cooling and setting device, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A laser film printing cooling and shaping device includes a frame, a conveyor drive device is provided on the frame, a conveyor belt is provided on the conveyor drive device, a plurality of cooling bags are equidistantly arranged on the outer surface of the conveyor belt, a liquid cooling mechanism for cooling the cooling bags is provided below the conveyor belt, the frame is located on one side of the printing device, and an air cooling mechanism is provided at the end of the frame near the printing device.

[0008] Preferably, the air-cooling mechanism includes a heat dissipation fan and a cooling fan, which are fixedly installed on one side of the frame.

[0009] Preferably, the first suction hood, the blower pipe, and the second suction hood are arranged sequentially from near to far on one side of the printing device, with one end of the blower pipe and the second suction hood being inclined relative to each other.

[0010] Preferably, the liquid cooling mechanism includes a plurality of semiconductor cooling chips, both ends of which are fixedly mounted on a mounting plate, and the mounting plate is fixedly mounted on a frame.

[0011] Preferably, a rotating shaft is rotatably provided on one side of the semiconductor cooling chip, and a plurality of cams are provided on the rotating shaft.

[0012] Preferably, the semiconductor cooling chip is slidably connected to the surface of the cooling bag, and the cam is slidably connected to the surface of the cooling bag.

[0013] Preferably, a motor is fixedly mounted on one end of the mounting plate, and the motor is fixedly connected to one end of one of the rotating shafts.

[0014] Preferably, a transmission wheel is fixedly fitted at one end of each of the rotating shafts, and a transmission belt is fitted on the transmission wheel.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The upper surface of the laser film is cooled by air cooling mechanism and the lower surface of the laser film is cooled by liquid cooling bag. The dual cooling methods work together to greatly accelerate the cooling and shaping speed of the laser film and avoid film quality problems caused by slow cooling.

[0017] (2) By setting up a liquid cooling mechanism, the cooling bag can be cooled when it rotates to one side, ensuring that the cooling bag always maintains good cooling performance, providing a stable guarantee for the continuous and effective cooling of the laser film surface, and improving the overall stability of the device.

[0018] (3) The conveyor belt and cooling bag are continuously moved by the conveyor drive device, which can be used in conjunction with the printing device to achieve continuous cooling and shaping of the laser film without interrupting the production process. It can be well adapted to the needs of continuous industrial production and has strong applicability. Attached Figure Description

[0025] 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.

[0026] like Figure 1 As shown in the figure, this utility model embodiment proposes a laser film printing cooling and shaping device, including a frame 1, a conveyor drive device 11 is provided on the frame 1, a conveyor belt 12 is provided on the conveyor drive device 11, a plurality of cooling bags 3 are equidistantly arranged on the outer surface of the conveyor belt 12, a liquid cooling mechanism 2 for cooling the cooling bags 3 is provided below the conveyor belt 12, the frame 1 is located on one side of the printing device 4, and an air cooling mechanism 5 is provided at the end of the frame 1 near the printing device 4.

[0027] The transmission drive device drives the conveyor belt 12 to rotate, causing several cooling bags 3 to move synchronously. The air-cooling mechanism 5 cools the upper surface of the newly printed laser film. The cooling bag 3 contacts the bottom of the laser film and cools the lower surface of the laser film. Through air cooling and liquid cooling of the cooling bag 3, the laser film is quickly cooled and shaped. When the cooling bag 3 rotates to the side of the liquid cooling mechanism 2, the liquid cooling mechanism 2 cools the cooling bag 3 to ensure the subsequent cooling effect of the cooling bag 3.

[0028] like Figure 1 , Figure 2 , Figure 3As shown, the air-cooling mechanism 5 includes a heat dissipation fan 51 and a cooling fan 52. The heat dissipation fan 51 and the cooling fan 52 are fixedly installed on one side of the frame 1. One end of the heat dissipation fan 51 is connected to a first suction hood 53 and a second suction hood 55, and one end of the cooling fan 52 is connected to a blower pipe 54. The first suction hood 53, the blower pipe 54 and the second suction hood 55 are arranged sequentially from near to far on one side of the printing device 4. One end of the blower pipe 54 and the second suction hood 55 are arranged at an angle relative to each other.

[0029] The cooling fan 51 draws in the hot air from the surface of the laser film after printing through the first suction hood 53, reducing heat accumulation around the film surface. The cooling fan 52 blows cold air onto the surface of the laser film through the blowing pipe 54 to actively cool the film surface. Then, the second suction hood 55 sucks away the residual heat generated after the cold air exchanges heat with the film surface. The three-stage air cooling process of "suction-blowing-re-suction" is adopted. Combined with the inclined blowing pipe 54 and the second suction hood 55, the hot air on the surface of the film after printing is effectively removed, and the film surface temperature is reduced by direct heat exchange with cold air. This improves the targeting and efficiency of air cooling, while avoiding the problem of uneven cooling caused by single blowing or suction.

[0030] like Figure 1 , Figure 4 , Figure 5 As shown, the liquid cooling mechanism 2 includes several semiconductor cooling chips 21. Both ends of the semiconductor cooling chips 21 are fixedly mounted on the mounting plate 24, which is fixedly mounted on the frame 1. A rotating shaft 22 is rotatably mounted on one side of the semiconductor cooling chip 21. Several cams 23 are mounted on the rotating shaft 22. The semiconductor cooling chip 21 is slidably connected to the surface of the cooling bag 3, and the cams 23 are rollably connected to the surface of the cooling bag 3. A motor 25 is fixedly mounted on one end of the mounting plate 24. The motor 25 is fixedly connected to one end of one of the rotating shafts 22. A transmission wheel 26 is fixedly sleeved on one end of each rotating shaft 22, and a transmission belt 27 is sleeved on the transmission wheel 26.

[0031] When the semiconductor cooling chip 21 is energized, it generates a low temperature. Its cold surface slides in contact with the surface of the cooling bag 3, providing continuous cooling to the cooling bag 3. The motor 25 drives one of the rotating shafts 22 to rotate, which drives all the rotating shafts 22 to rotate synchronously through the transmission wheel 26 and the transmission belt 27. This causes the cam 23 on the rotating shaft 22 to roll with the rotating shaft 22 and contact the surface of the cooling bag 3. The rolling of the cam 23 will periodically squeeze the cooling bag 3, forcing the cooling medium inside the cooling bag 3, such as coolant or cooling gel, to flow. This avoids uneven local temperature caused by the cooling medium being stationary, improves the uniformity of the surface temperature of the cooling bag 3, provides a reliable cooling basis for subsequent contact with the laser film for cooling, and improves the stability and cooling efficiency of the liquid cooling system.

[0032] The working principle of this laser film printing cooling and setting device:

[0033] The conveyor drive device 11 drives the conveyor belt 12 to move synchronously, causing several cooling bags 3 to move. After the printed laser film is output from the printing device 4, the air cooling mechanism 5 cools the upper surface of the laser film. At the same time, the cooling bags 3 moving with the conveyor belt 12 contact the bottom of the laser film and cool the lower surface of the laser film. Through the dual effects of air cooling and liquid cooling of the cooling bags 3, the laser film is quickly cooled and shaped. When the cooling bags 3 rotate with the conveyor belt 12 to the side of the liquid cooling mechanism 2, the semiconductor cooling chip 21 is energized and cooled. Driven by the motor 25, the transmission wheel 26, and the transmission belt 27, the rotating shaft 22 drives the cam 23 to roll. The cam 23 squeezes the cooling bags 3 to make the internal cooling medium flow, and at the same time, the cooling bags 3 are in full contact with the semiconductor cooling chip 21 and are cooled evenly, ensuring that the cooling bags 3 keep low temperature and achieving continuous and efficient cooling and shaping of the printed laser film.

[0034] 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.
