Description

[0002] The polyimide thin film is one of the earliest commercial products of polyimide, and is used for slot insulation of motors and cable wrapping materials. Due to its excellent mechanical properties, outstanding thermal stability and heat resistance, good corrosion resistance and insulation performance, the polyimide thin film has become one of the important raw materials in the electrical and electronic fields. At present, some of the existing ones are mostly large-scale equipment and are not easy to carry. The drying method of heating and blowing will cause local wrinkling, high-temperature damage and charring of the polyimide thin film, and there are also some disadvantages such as large heat loss, low energy utilization rate and lack of energy saving.

When the second spur gear 51 rotates to the toothless section of the second rack 52, it will stop driving the second rack 52 to continue moving towards one end. The movement of the second rack 52 towards one end will drive the third connecting rod 53 towards one end. The movement of the third connecting rod 53 towards one end will drive the stopper 55 towards one end. The movement of the stopper 55 towards one end will compress the spring 56. While the second rack 52 is moving towards one end, it will drive the second sliding block 57 towards one end. The movement of the second sliding block 57 towards one end will drive the hollow groove 58 away from the rubber block 510. At this time, the hot air inside the hollow groove 58 will enter the first sleeve 113 through the fourth sleeve 59 and the first connecting pipe 121. The hot air inside the first sleeve 113 will flow to the inside of the sliding plate 111. The hot air inside the sliding plate 111 will escape from the small holes 112 provided inside to dry both sides of the film 118 simultaneously. When the motor 41 stops rotating, at this time the spring 56 will drive the stopper 55 to move outwards and reset. The outward movement and reset of the stopper 55 will drive the third connecting rod 53 to move outwards and reset. The outward movement and reset of the third connecting rod 53 will drive the second rack 52 to move outwards and reset. Through the sliding cooperation between the set second sliding block 57 and the rubber block 510, the drying hot air switch for the film 118 can be automatically adjusted. When the motor 41 is started, the film 118 will be automatically dried. When the motor 41 is turned off, the drying of the film 118 will stop. In this way, the drying of the film 118 is convenient and fast.
