DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model provides a technical solution: a diaphragm drying device for lithium battery processing, comprising a chassis 1, an inner cavity 20 is opened inside the chassis 1, a diaphragm 11 passes through the inner cavity 20, and the inner cavity 20 is rotatably connected to an inner roller 10 through a rotating shaft;

[0025] A drying component 2, wherein the drying component 2 is located inside the inner cavity 20, and can tighten the diaphragm 11 while drying the diaphragm 11, thereby improving the utilization rate of the drying component 2;

[0026] The adjusting component 3 can adjust the drying component 2 so that it can better dry the diaphragm 11, which is beneficial to improving the quality of the diaphragm 11.

[0027] The drying component 2 includes a socket 28, which is opened on the outer surface of the chassis 1, and an air supply pipe 27 is fixedly connected to the socket 28. A heating roller 21 is connected to the inner surface of the inner cavity 20. An air supply port 29 is opened at the end of the heating roller 21, and the air supply port 29 is aligned with the air supply pipe 27. A through groove 26 is provided on the outer surface of the heating roller 21, and hot air is transported to the inside of the heating roller 21 through the air supply pipe 27. The heating roller 21 is inside the inner cavity 20 as a whole and rotates on the traction line of the diaphragm 11. The hot air is ejected through the through groove 26 to dry the diaphragm 11. The diaphragm 11 is blocked by the inner roller 10 and the heating roller 21 and is in a taut state, so as to avoid a decrease in the drying effect due to wrinkles during drying, thereby ensuring the quality of the diaphragm 11.

[0028] The heating roller 21 includes a directional disk 23, the air supply port 29 is opened through the end of the directional disk 23, and the directional disk 23 is rotatably connected to the inner cavity 20 through a bearing, and the end of the directional disk 23 away from the air supply port 29 is fixedly connected with a baffle 1 24, the heating roller 21 also includes an adjusting disk 22, and the adjusting disk 22 is connected to the adjusting component 3. The number of baffles 1 24 is four groups, and two adjacent positions of the baffles 25 are slidably connected, and the end of the baffle 2 25 away from the directional disk 23 is fixedly connected to the adjusting disk 22, and the baffles 1 24 and the baffles 2 25 are staggered with each other, and the hot air is discharged through the staggered area and the through groove 26 to dry the diaphragm 11. Because of the setting of the inner roller 10, the hot air will flow inside the channel formed by the diaphragm 11, further ensuring the drying effect.

[0029] The outer surfaces of the baffle plate 1 24 and the baffle plate 2 25 are both designed with an arc-shaped structure, and the two are matched with each other, and the surfaces have arcs, which can better contact with the diaphragm 11.

[0030] The outer surfaces of the baffle plate 1 24 and the baffle plate 25 are both provided with through grooves 26, and the hot air is sent out from the overlapping area of ​​the baffle plate 1 24 and the baffle plate 2 25 through the through grooves 26 to dry the diaphragm 11;

[0031] The adjusting component 3 includes a mounting groove 31, and the mounting groove 31 is provided on the outer surface of the chassis 1. An electric telescopic rod 30 is fixedly connected inside the mounting groove 31. The electric telescopic rod 30 is rotatably connected to the adjusting disk 22. The electric telescopic rod 30 pushes the adjusting disk 22, and the adjusting disk 22 drives the baffle plate 25 to move along the baffle plate 1 24, thereby changing the overall length of the heating roller 21, so as to heat and dry the diaphragms 11 of different widths. While shortening the overall length of the heating roller 21 to be equal to the diaphragm 11, the gap between the baffle plate 1 24 and the baffle plate 2 25 will also be reduced, thereby reducing the overflow of the hot air when drying the diaphragm 11.
