[0021] See also Figure 1 The present application discloses a drying apparatus 100 for a film 40, comprising a drying oven 10, a rotating shaft heater 20, and conveyor rollers 30. The rotating shaft heater 20 comprises a heating rod 21 and heat-conducting fins 22 disposed on the periphery of the heating rod 21. The heating rod 21 is rotatably mounted within the drying oven 10. A plurality of conveyor rollers 30 are disposed within the drying oven 10 and surround the rotating shaft heater 20, ensuring that the conveyor path of the film 40 is close to and around the periphery of the rotating shaft heater 20.

[0022] The drying equipment 100 of the present application solves the technical problems of low drying efficiency and high energy consumption in conventional film 40 drying equipment 100 by combining an innovatively designed rotary heater 20 with a transmission roller 30. Specifically, the rotary heater 20 is disposed within the drying oven 10, and its heating rod 21 is provided with heat-conducting fins 22 on the periphery, effectively expanding the heating area and improving heat transfer efficiency. At the same time, multiple transmission rollers 30 surround the periphery of the rotary heater 20, so that the transmission path of the film 40 is closely attached to and surrounds the rotary heater 20, thereby ensuring that the film 40 can receive heat evenly and efficiently during transmission, achieving a fast and uniform drying effect. This design not only improves drying efficiency, but also significantly reduces energy consumption, meeting the urgent demand for high efficiency and energy saving in modern industrial production.

[0023] Specifically, see Figure 1 、 Figure 2 and Figure 3Rotary heaters 20 are located in the upper left and lower right portions of the drying oven 10, symmetrically about the center of the drying oven 10. For ease of explanation, the rotary heater 20 in the upper left corner of the drying oven 10 is used as an example. Three transport rollers 30 surround the rotary heater 20: one located in the lower left corner and two located above it. The adhesive film 40 first passes over the lower left transport roller 30, then passes over the two upper transport rollers 30, and then is transported downward to the lower right corner to the rotary heater 20. This forms a downward-facing "U"-shaped first path 50 around the outer perimeter of the rotary heater 20. The upward-facing "U"-shaped second path 60 surrounding the rotary heater 20 on the lower right side of the drying oven 10 follows the same principle and will not be further described. The first and second paths 50, 60, are rotationally symmetrical about the center of the drying oven 10. The first path 50 is used to dry moisture from the downward surface of the adhesive film 40, while the second path 60 is used to dry moisture from the upward surface of the adhesive film 40. In other embodiments, a triangular path surrounding method may also be adopted.

[0024] See also Figure 1 and Figure 2 The drying box 10 is provided with an air inlet 11 and an air outlet 12. The air inlet 11 is provided with an air purification module 111. The air purification module 111 is used to purify and remove moisture from the air introduced into the box. The air outlet 12 is provided with a filter 121. The filter 121 is used to prevent external dust from entering the box. Specifically, the air inlet 11 is provided on the lower left and upper right sides of the drying box 10. The air inlet 11 is provided with an air purification module 111. The air outlet 12 is provided on the upper left and lower right sides of the drying box 10. The air outlet 12 is provided with a filter 121 to prevent external air from entering the box when the drying box 10 is not working.

[0025] The air guide fan 131 is installed in the drying box 10 and is used to guide the airflow from the air inlet 11 to the rotary shaft heater 20, and the rotary shaft heater 20 rotates clockwise. Specifically, the drying box 10 is provided with a mounting plate 13, an air guide plate 14 and a flow guide plate 15. For the sake of convenience, the mounting plate 13, the flow guide plate 15 and the air guide plate 14 at the lower left side of the drying box 10 are used for explanation. The mounting plate 13 is set at the lower left corner of the rotary shaft heater 20 on the upper left side of the drying box 10, and a slot for installing the air guide fan 131 is set on the mounting plate 13. The air guide plate 14 is located on the left side of the connection path between the first path 50 and the second path 60, and the air guide plate 14 is parallel to the connection path. The flow guide plate 15 is inclined relative to the air guide plate 14, and the two ends of the air guide plate 15 are respectively connected to the mounting plate 13 and the air guide plate 14. The two air guide plates 14 are respectively located on both sides of the connection path between the first path 50 and the second path 60. The air guide plate 14 , the inner surface of the bottom of the drying box 10 and the lower surface of the adhesive film 40 form a channel for air flow.

[0026] The following is an explanation of the working process of the drying device 100. For the sake of convenience, the following explanation is based on the drying of the lower side of the film 40. The same applies to the upper side. Figure 2 Starting from the dashed arrow on the lower left side of the drying oven 10, when the drying oven 10 is in operation, the film 40 enters from the left side of the drying oven 10 (in the direction of the solid arrow near the film 40 in the figure), is transported along the conveyor roller 30, and exits the right side of the drying oven 10. At this time, the rotary heater 20 on the upper left side of the drying oven 10 heats up and rotates clockwise, and the air guide 131 is turned on. Outside air passes through the air purification module 111 on the lower left side of the drying oven 10, purified and dried, and then enters the oven. The air then reaches the air guide 131, which directs the airflow to the left of the rotary heater 20. The rotary heater 20 dries and dehumidifies the film 40 that has just entered. Driven by the rotary heater 20 and the air guide 131, a clockwise airflow is formed within the downwardly opening "U"-shaped first path 50, drying the lower surface of the film 40. After the air flows out of the first path 50 , it continues to flow to the second path 60 under the action of the guide plates 15 and 14 , continues to dry the lower surface of the film 40 , and is finally discharged from the air outlet 12 on the lower right side of the drying box 10 .

[0027] The drying equipment 100 also includes a moisture detector 70, which is used to detect the moisture content on the surface of the film 40 in the embodiment of the present application. The moisture detector 70 is an infrared moisture detector 70. Of course, other methods can also be used to test the moisture on the film 40, which will not be described in detail in this application. The moisture detector 70 can be installed outside the drying box 10, or it can be installed outside the drying box 10. In the embodiment of the present application, two upper and lower moisture detectors 70 are provided at the feed port and the discharge port of the drying box 10. The rotating shaft heater 20 can increase the heating power according to the value detected by the detector to ensure that the dry film 40 can be obtained.
