Description

Technical Field

[0001] The utility model relates to the technical field of covering film air-drying devices, in particular to an air-drying cabinet for accelerating the solidification of glue of a covering film on the surface of a film. Background Art

[0002] During the processing of film-type insulating materials, a layer of coating needs to be evenly covered on both the front and back surfaces of the film and then air-dried and cured.

[0003] In the current prior art, a special glue is required to stick a covering film on a film. The glue becomes liquid and sticky only at high temperatures. Therefore, after the covering film is attached to the surface of the film, in order to accelerate its cooling and solidification, it is generally rolled up and placed on a transfer piece, and then placed in an air-drying cabinet for air drying. However, the air inlet of the existing air-drying cabinet is generally arranged on the side or bottom of the cabinet. Although it can also achieve the effect of air drying, since the air outlet is arranged on the bottom or side, the outside wind can only pass through the cabinet unilaterally after entering, and does not directly blow on the film covering the surface of the film in the cabinet. As a result, the air drying effect is often not ideal. However, if a cold air nozzle is directly arranged, the local temperature will be too low, which will easily damage the film covering the surface of the film. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an air-drying cabinet for accelerating the solidification of glue on a film surface covering film, which solves the problem in the prior art that the air-drying cabinet cannot blow cold air evenly when air-drying the film surface covering film.

[0005] According to the technical solution of the utility model, an air-drying cabinet for accelerating the solidification of glue covering the surface of a thin film comprises a cabinet body, an air-drying chamber is arranged in the cabinet body, and the air-drying chamber comprises an air inlet section located on one side of the upper end of the cabinet body and an air-drying section located below the air inlet section; an installation chamber is also arranged in the cabinet body, and an inclined filter screen is installed between the installation chamber and the air inlet section, a cooling mechanism is installed in the installation chamber, and an air inlet channel communicating with the installation chamber is fixedly connected to the cabinet body; an air outlet channel communicating with the inside and outside of the air-drying section is also arranged on the cabinet body.

[0006] The technical principle of the utility model is: the staff first puts the transfer piece equipped with the film surface covering film into the air-drying section in the air-drying chamber, and then closes the rotating door to ensure that the rotating door is closed, and then starts the cooling mechanism to allow the cold air to come out through the cooling mechanism. Since the cooling mechanism is inclined, the cold air will hit the side wall of the air-drying section in the air-drying chamber, so that the cold air passes through the side wall in the air-drying section in the air-drying chamber and hits the transfer piece equipped with the film surface covering film, and at the same time forms a backflow vortex, so as to evenly blow the film surface covering film, and will not cause local cooling to damage the covering film. In this way, the problem that the cold air cannot be blown evenly when the film surface covering film is air-dried in the air-drying cabinet in the prior art is solved.

[0007] Compared with the prior art, the utility model has the following beneficial effects: by designing the cooling mechanism at an angle in the air inlet section in the air-drying chamber, the cold air hits the side wall of the air-drying section in the air-drying chamber and then blows evenly on the film covering the surface of the film, forming a reflux vortex, thereby solving the problem in the prior art that the cold air cannot be blown evenly when the film covering the surface of the film is air-dried in the air-drying cabinet.

DETAILED DESCRIPTION

[0011] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0012] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0013] like Figure 1-2As shown, an embodiment of the utility model proposes an air-drying cabinet for accelerating the solidification of glue covering the surface of a thin film, which includes a cabinet body 1, and an air-drying chamber 2 is arranged in the cabinet body 1, and the air-drying chamber 2 includes an air inlet section located on one side of the upper end of the cabinet body 1 and an air-drying section located below the air inlet section; an installation chamber 3 is also arranged in the cabinet body 1, and an inclined filter screen 4 is installed between the installation chamber 3 and the air inlet section, a cooling mechanism 5 is installed in the installation chamber 3, and an air inlet channel 9 connected to the installation chamber 3 is fixedly connected to the cabinet body 1; an air outlet channel 10 connected to the inside and outside of the air-drying section is also arranged on the cabinet body 1.

[0014] Specific operation process: the staff first puts the transfer piece with the film surface covering film into the air-drying section in the air-drying chamber 2, then closes the rotating door 7, and after ensuring that the rotating door is closed, starts the cooling mechanism 5, so that the cold air passes through the cooling mechanism 5 and comes out. Since the cooling mechanism 5 is designed to be inclined, the cold air will hit the side wall of the air-drying section in the air-drying chamber 2, so that the cold air passes through the side wall of the air-drying section in the air-drying chamber 2 and hits the transfer piece with the film surface covering film, and at the same time forms a reflux vortex. The reflux vortex is as follows: Figure 1 As shown by the arrow, the film covering the surface of the film is evenly blown, and local cooling will not be caused to damage the covering film. The cooling mechanism 5 is tilted in the air inlet section of the air drying chamber 2, so that the cold air hits the side wall of the air drying section in the air drying chamber 2 and then blows evenly on the film covering the surface of the film to form a reflux vortex, thereby solving the problem in the prior art that the cold air cannot be blown evenly when the film covering the surface of the film is air-dried in the air drying cabinet.

[0015] According to one embodiment of the utility model, Figure 1 As shown, a drying cabinet for accelerating the solidification of glue covering the surface of a film, the cooling mechanism 5 includes a fan 501 and a drive motor 502, the drive motor 502 is fixedly connected to the air inlet channel 9 in the cabinet 1, and a rotating shaft is fixedly connected in the middle of the fan 501, and the fan 501 is rotatably connected to the drive motor 502 via the rotating shaft. In this solution, the drive motor 502 drives the rotating shaft to rotate, and the rotating shaft further drives the fan 501 on its outer ring to rotate, thereby realizing the suction of air from the air inlet channel 9, accelerating it to rush into the cabinet 1, and generating airflow.

[0016] According to one embodiment of the utility model, Figure 1-2As shown, a drying cabinet for accelerating the solidification of glue covering the surface of a film, the cooling mechanism 5 also includes a fixed shaft 503, and the fixed shaft 503 is fixedly installed between the fan 501 and the filter 4, and a heat exchange coil 504 is arranged on the outside of the fixed shaft 503 to rotate and surround the fixed shaft 503. In this solution, the fixed shaft 503 is used to fix the heat exchange coil 504 on its outside to ensure that the airflow will pass through the heat exchange coil 504, and the heat exchange coil 504 is located between the fan 501 and the filter 4, so that the gas entering the cabinet 1 will absorb heat.
