[0037] It should be noted that by starting the motor 2 44, the upper shaft 46 is driven to rotate clockwise, thereby causing the upper half-tooth gear 47 to rotate clockwise, and the half-tooth gear 47 is meshed with the tooth plate 43, which will drive the partition 42 to move leftward. When the half-tooth gear 47 rotates half a circle, it will not mesh with the tooth plate 43. During the rotation of the shaft 46, the upper rotating wheel 45 will be driven to rotate clockwise, thereby driving the lower rotating wheel 45 to rotate clockwise, thereby causing the lower half-tooth gear 47 to rotate clockwise, thereby The partition 42 is driven to move to the right, and the rotating shaft 46 is continuously rotated, so that the fixed frame 41 moves back and forth left and right, and then drives the ventilation box 38 to move back and forth left and right, so that the limit block 401 set at the rear moves along the limit groove 49. The limit groove 49 and the limit block 401 are both T-shaped blocks, which ensures that the ventilation box 38 will not fall, and the hot air will not always be directed to the same position of the PET protective film coating 2, so that the drying effect can be more uniform, achieving a better drying effect.

[0042] The working principle of the utility model is as follows: by starting the motor 32, the connecting shaft 301 will be driven to rotate clockwise, and then the plurality of fan blades 33 will be driven to rotate clockwise. The fan blades 33 are arranged in an inclined plate shape, so that the external wind can be driven into the connecting box 31 through the ventilation slots on the connecting box 31. At this time, the heating tube 34 is energized so that the heating tube 34 emits a certain amount of heat. Driven by the fan blades 33, the heat will be driven into the ventilation pipe 36, and the hot air will enter the two ventilation boxes 38 through the heat-resistant telescopic tube 37.

The upper and lower parts are heated at the same time, so that the drying effect is better. By starting the motor 44 , driving the upper rotating shaft 46 to rotate clockwise, thereby causing the upper half-toothed gear 47 to rotate clockwise, and the half-toothed gear 47 is meshed with the toothed plate 43, which will drive the partition 42 to move to the left. When the half-toothed gear 47 rotates half a circle, it will not mesh with the toothed plate 43. During the rotation of the rotating shaft 46, it will drive the upper rotating wheel 45 to rotate clockwise, thereby driving the lower rotating wheel 45 to rotate clockwise, thereby causing the lower half-toothed gear 47 to rotate clockwise, thereby driving the partition 42 to move to the right, and the rotating shaft 46 is continuously rotated. The movement causes the fixing frame 41 to move back and forth left and right, thereby driving the ventilation box 38 to move back and forth left and right, so that the limit block 401 set at the rear moves along the limit groove 49. The limit groove 49 and the limit block 401 are both T-shaped blocks, which ensures that the ventilation box 38 will not fall. At the same time, the heat-resistant telescopic tube 37 will be repeatedly stretched and compressed, so that the hot air can always be blown out, and the hot air will not always be directed to the same position of the PET protective film coating 2, so that the drying effect can be more uniform, achieving a better drying effect.
