[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 As shown, a drying device for photovoltaic film production includes an outer cylinder 1 and a drying component 2. The drying component 2 is installed on the top of the outer cylinder 1, and a geared motor 3 is installed on one side of the outer cylinder 1. A fixed shaft 4 is fixedly connected to the output end of the geared motor 3, and a spiral disk 5 is fixedly connected to the outside of the fixed shaft 4. One end of the fixed shaft 4 is rotatably connected to the inner wall of the outer cylinder 1 through a bearing seat. An exhaust pipe is connected to the top of the outer cylinder 1. A feeding trough 6 is connected to the top of the outer cylinder 1. An anti-blocking component 7 is installed inside the feeding trough 6, and a protective component 8 is installed on one side of the feeding trough 6.

[0022] The drying assembly 2 includes a hot air blower 21 located at the top of the outer cylinder 1. The air outlet of the hot air blower 21 penetrates the inner wall of the outer cylinder 1 and is connected to a connecting pipe 22. Multiple air outlets 23 are provided on the outside of the connecting pipe 22.

[0023] The bottom of the outer cylinder 1 is connected to a discharge pipe 9, and a valve 10 is installed on the outside of the discharge pipe 9.

[0024] The photovoltaic film raw material is fed into the feeding trough 6, and the anti-blocking component 7 is activated to stir the raw material to prevent it from clogging in the feeding trough 6. After the raw material enters the outer cylinder 1 through the feeding trough 6, the reduction motor 3 is activated to drive the fixed shaft 4 to rotate the spiral disk 5, thereby moving the raw material along the spiral disk 5 and tumbling during the movement. At this time, the hot air blower 21 is activated. The heat generated by the electric heating wire inside the blower exchanges heat with the passing cold air, thereby raising the temperature of the air outlet. The hot air enters the connecting pipe 22 and is evenly blown into the outer cylinder 1 from multiple sets of air outlets 23 to dry the photovoltaic film raw material, improving the drying efficiency of the raw material. The moisture in the outer cylinder 1 is discharged from the exhaust pipe, and the dried material is discharged through the discharge pipe 9.

[0025] The anti-blocking component 7 includes a motor 71 disposed on one side of the feed trough 6. The output end of the motor 71 is fixedly connected to a connecting shaft 72. There are two connecting shafts 72. One end of the other connecting shaft 72 is rotatably connected to the inner wall of the feed trough 6 through a bearing seat. A mixing plate 73 is fixedly connected to the outer side of both connecting shafts 72.

[0026] The anti-blocking assembly 7 also includes a driving wheel 74 and a driven wheel 75, which are respectively fixed to one end of the two connecting shafts 72. The outer side of the driving wheel 74 is engaged with the outer side of the driven wheel 75.

[0027] After the material enters the feed trough 6, the motor 71 is started, causing one of the connecting shafts 72 to drive the mixing plate 73 and the drive wheel 74 to rotate. Since the outer side of the drive wheel 74 is meshed with the outer side of the driven wheel 75, the driven wheel 75 rotates synchronously with the drive wheel 74, and the other connecting shaft 72 drives the mixing plate 73 to rotate. The cooperation of the two sets of connecting shafts 72 facilitates the dispersion of the raw materials in the feed trough 6 and avoids the material from clogging inside.

[0028] The protective assembly 8 includes a protective shell 81 fixed to one side of the feed trough 6. The protective shell 81 is located outside the drive wheel 74 and the driven wheel 75. The top of the protective shell 81 is connected to a diversion pipe 82, and the outside of the diversion pipe 82 is connected to a number of oil outlets 83.

[0029] The protective assembly 8 also includes an oil receiving tray 84 located at the bottom of the inner cavity of the protective housing 81, and a filter screen 85 is attached to the inner wall of the oil receiving tray 84.

[0030] Lubricating oil is poured into the distributor pipe 82 and dripped from several oil outlets 83 onto the driving wheel 74 and driven wheel 75, thereby reducing wear between gears. The protective shell 81 prevents dust and impurities from adhering to the two gears, while the oil dripping from the gears is collected through the oil receiving pan 84 to avoid oil waste. The collected oil can be filtered through the filter screen 85 for easy reuse.

[0031] Working principle: The photovoltaic film raw material is put into the feeding trough 6. The anti-blocking component 7 is activated to stir the raw material to prevent it from clogging in the feeding trough 6. After the raw material enters the outer cylinder 1 through the feeding trough 6, the reduction motor 3 is activated to drive the fixed shaft 4 to rotate the spiral disk 5, thereby moving the raw material along the spiral disk 5 and tumbling during the movement. At this time, the hot air fan 21 is activated to allow hot air to enter the connecting pipe 22 and be evenly blown into the outer cylinder 1 from multiple sets of air outlets 23 to dry the photovoltaic film raw material, which improves the drying efficiency of the raw material. The moisture in the outer cylinder 1 is discharged from the exhaust pipe, and the dried material is discharged through the discharge pipe 9.
