Description

Technical Field

[0001] This utility model relates to the field of TPU film storage technology, specifically a TPU film storage box. Background Technology

[0002] TPU film storage refers to the process of storing TPU film under specific environmental conditions after it has been produced in order to maintain its performance and quality until it is used for subsequent processing, sales or other purposes. In order to ensure the storage quality of TPU film and reduce the contact between TPU film and external environment, it is necessary to use appropriate storage boxes to isolate TPU film from external environment.

[0003] The existing utility model with authorization announcement number CN215904917U discloses an EVA plastic film storage box with good moisture-proof effect. The EVA plastic film storage box with good moisture-proof effect has a good moisture-proof effect by placing the storage box inside the protective shell. The moisture-proof effect of the device is further enhanced by setting a locking mechanism and a ventilation mechanism.

[0004] While the above technical solutions offer some moisture protection, they fail to consider that the ideal storage temperature for TPU films is generally between 15°C and 25°C. Within this temperature range, the physical and chemical properties of TPU films are relatively stable. However, the lack of intelligent temperature control means that excessively high temperatures can cause the TPU film to soften, become more viscous, and even stick together. Conversely, excessively low temperatures can cause the TPU film to become brittle, reducing its flexibility and tensile strength, thus affecting the quality of the TPU film during storage.

[0005] Therefore, those skilled in the art have provided a TPU film storage box to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide a TPU film storage box to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A TPU film storage box includes a protective box, the bottom surface of which is movably hinged with a sealing door, and the interior of which is equipped with an intelligent temperature control mechanism;

[0009] The intelligent temperature control mechanism includes four hollow shells. A heating plate is fixedly connected to the inner bottom wall of the protective box. Heat-conducting fins are fixedly connected to the upper surface of the heating plate and the inner top wall of the protective box. A semiconductor cooling chip and a heat dissipation fan are fixedly connected to the inner wall of each hollow shell. Heat dissipation fins are fixedly connected to the upper surface of each semiconductor cooling chip. A button controller is fixedly connected to the front of the sealed door. A temperature sensor is fixedly connected to the back of the sealed door. Three hollow support plates are fixedly connected to the inner walls of both sides of the protective box.

[0010] As a further embodiment of this utility model: the outer surface of each hollow shell is fixedly connected to the inner wall of the protective box, the bottom surface of each hollow shell is fixedly connected to the upper surface of one of the heat-conducting fins, the bottom surface of each semiconductor cooling chip is in contact with the upper surface of one of the heat-conducting fins, the heating plate, the four semiconductor cooling chips, the four cooling fans and the temperature sensor are all electrically connected to the button controller through wires, the two sides of the protective box are fixedly connected with fixing rods, and the two sides of the sealing door are fixedly connected with limit rods.

[0011] As a further improvement of this utility model: both sides of the protective box are provided with limiting plates, the inner wall of each limiting plate is rotatably connected to the outer surface of the fixing rod, and the interior of each limiting plate is engaged with the outer surface of the limiting rod.

[0012] As a further improvement of this utility model: the bottom surface of the protective box is fixedly connected to four pads, and the bottom surface of each pad is fixedly connected to an anti-slip pad.

[0013] As a further improvement of this utility model: two handle supports are fixedly connected to the front of the sealing door, and a pull rod is fixedly connected to the inner wall of each handle support.

[0014] As a further improvement of this utility model: each of the handle supports is provided with a grip inside, and the inner wall of each grip is rotatably connected to the outer surface of the pull rod.

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

[0016] This invention utilizes the coordinated components of a protective box, a sealed door, a perforated shell, a heating plate, heat-conducting fins, a semiconductor cooling chip, heat dissipation fins, a cooling fan, a temperature sensor, a button controller, and a perforated tray. The perforated tray can hold the rolled-up TPU film, and its opening facilitates airflow and heat conduction within the protective box. The temperature sensor monitors the temperature inside the protective box. When the temperature is below the temperature range set by the button controller, the button controller activates the heating plate to generate heat, transferring the heat to the interior space of the protective box through the heat-conducting fins below. Conversely, when the temperature is above the temperature range set by the button controller, the button... The controller can energize the semiconductor cooling chip, activate the bottom cooling system, and power the heat dissipation fan for exhaust. This allows the heat-conducting fins above to quickly remove excess heat from the protective box until the temperature reaches the midpoint of the temperature range set by the button controller. This effectively controls the ambient temperature of the rolled-up TPU film on the perforated tray inside the protective box, ensuring its storage quality. It avoids the problems caused by a lack of intelligent temperature control, where excessively high temperatures can soften the TPU film, increase its stickiness, and even cause it to stick together, while excessively low temperatures can make the TPU film brittle, reducing its flexibility and tensile strength, thus affecting the quality of the TPU film during storage.

[0024] Please see Figure 1-6 A TPU film storage box includes a protective box 1, a sealing door 2 hinged to the bottom of the protective box 1, an intelligent temperature control mechanism 3 inside the protective box 1, the intelligent temperature control mechanism 3 including four hollow shells 301, an electric heating plate 302 fixedly connected to the inner bottom wall of the protective box 1, the outer surface of each hollow shell 301 fixedly connected to the inner wall of the protective box 1, fixing rods 4 fixedly connected to both sides of the protective box 1, and limit rods 5 fixedly connected to both sides of the sealing door 2. By setting the fixing rods 4, a rotation base surface can be provided for other limit structures, thereby increasing the flexibility of the use of the limit structure. By setting the limit rods 5, the limit structure can be limited.

[0025] The upper surface of the heating plate 302 and the inner top wall of the protective box 1 are both fixedly connected with heat-conducting fins 303. The inner wall of each hollow shell 301 is fixedly connected with a semiconductor cooling chip 304 and a cooling fan 306. The bottom surface of each hollow shell 301 is fixedly connected to the upper surface of one of the heat-conducting fins 303. The bottom surface of each semiconductor cooling chip 304 is in contact with the upper surface of one of the heat-conducting fins 303. Limiting plates 6 are provided on both sides of the protective box 1. The inner wall of each limiting plate 6 is rotatably connected to the outer surface of the fixing rod 4. The inside of each limiting plate 6 is engaged with the outer surface of the limiting rod 5. By setting the limiting plate 6, it can rotate around the outer surface of the fixing rod 4 and engage with the outer surface of the limiting rod 5, thereby temporarily locking the sealing door 2 relative to the protective box 1.

[0026] Each semiconductor cooling chip 304 has a heat dissipation fin 305 fixedly connected to its upper surface. A button controller 308 is fixedly connected to the front of the sealing door 2. Four pads 10 are fixedly connected to the bottom of the protective box 1. Each pad 10 has an anti-slip pad 11 fixedly connected to its bottom surface. By setting the pads 10, the protective box 1 can be raised, thereby leaving space under the protective box 1 for easy handling of the entire storage box. By setting the anti-slip pads 11, the anti-slip properties of the bottom surface of the pads 10 can be increased.

[0027] A temperature sensor 307 is fixedly connected to the back of the sealed door 2. The heating plate 302, four semiconductor cooling chips 304, four cooling fans 306 and the temperature sensor 307 are all electrically connected to the button controller 308 through wires. Two handle supports 7 are fixedly connected to the front of the sealed door 2. A pull rod 8 is fixedly connected to the inner wall of each handle support 7. By setting the pull rod 8, a rotation base surface can be provided for the hand grip structure inside the handle support 7, thereby increasing the flexibility of the hand grip structure. By setting the handle support 7 and the pull rod 8, the sealed door 2 can be pulled together with the above-mentioned hand grip structure, thereby facilitating the opening and closing of the sealed door 2 relative to the protective box 1.

[0028] Three hollowed-out support plates 309 are fixedly connected to the inner walls of both sides of the protective box 1. Each handle support 7 has a handle 9 inside. The inner wall of each handle 9 is rotatably connected to the outer surface of the pull rod 8. By setting the handle 9, it can rotate around the outer surface of the pull rod 8 inside the handle support 7, so that it can be easily pulled by hand after being gripped, thus facilitating the opening and closing of the sealed door 2 relative to the protective box 1.

[0029] The working principle of this utility model is as follows: During use, the rolled-up TPU film is evenly placed on the perforated tray 309 with gaps. The sealing door 2 and the protective box 1 are closed, and the limiting plate 6 is rotated around the fixing rod 4 and then engaged with the limiting rod 5. The desired temperature range can be controlled by operating the button controller 308. When the temperature sensor 307 detects that the temperature inside the protective box 1 is lower than the temperature range set by the button controller 308, the button controller 308 controls the heating plate 302 to be energized and heat up, transferring the heat to the interior space of the protective box 1 through the lower heat-conducting fins 303, until the temperature sensor 307 detects that the temperature inside the protective box 1 reaches the midpoint of the temperature range set by the button controller 308. When this temperature is higher than the temperature range set by the button controller 308, the button controller... The device 308 controls the semiconductor cooling chip 304 to be energized, and the bottom cooling and heat dissipation fan 306 to be energized for exhaust. In turn, the heat-conducting fins 303 above quickly remove excess heat from the protective box 1 until the temperature sensor 307 detects that the temperature inside the protective box 1 has reached the middle value of the temperature range set by the button controller 308. This effectively controls the ambient temperature of the rolled-up TPU film carried on the hollow tray 309 inside the protective box 1 and ensures its storage quality. The design of the entire TPU film storage box effectively solves the problem that due to the lack of an intelligent temperature control structure, excessively high temperatures will cause the TPU film to soften, increase its stickiness, and even stick together. Excessively low temperatures will cause the TPU film to become brittle, reducing its flexibility and tensile strength, thus affecting the quality of the TPU film during storage.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
