DETAILED DESCRIPTION
[0019] The following description is only a preferred embodiment of the present invention and does not limit the protection scope of the present invention.
[0020] Example 1
[0021] A lithium battery separator rapid baking and shaping device, such as Figure 1-Figure 3As shown, it includes a baking box 1, a coiling roller 2, a diaphragm 201, a hot air blower 3, an air inlet pipe 4, an air outlet frame 5, a guide roller 6 and a limit plate 19. The outside of the baking box 1 is connected to the coiling roller 2, and the diaphragm 201 is connected between the two coiling rollers 2. The hot air blower 3 is installed on the right side of the baking box 1. The hot air blower 3 is connected to the air inlet pipe 4, and the air inlet pipe 4 runs through the baking box 1. The air inlet pipe 4 is connected to the air outlet frame 5, which can spray hot air onto the diaphragm 201. The inside of the baking box 1 is connected to the guide roller 6, and the diaphragm 201 is in contact with the guide roller 6. The limit plate 19 is connected between the three guide rollers 6 to limit the diaphragm 201. It also includes an arc plate 7 and a heating tube 8. The inner wall of the baking box 1 is connected to the arc plate 7 to support the heating tube 8. The heating tube 8 is installed on the arc plate 7 to heat the diaphragm 201.
[0022] like Figure 3 and Figure 4 As shown, it also includes a revolving door 9, a connecting block 10, a mounting frame 12, a telescopic rod 13, a wedge block 14, a toggle plate 15 and a sealing strip 16. The right side of the baking oven 1 is rotatably connected to the revolving door 9, and the connecting block 10 is connected to the revolving door 9. The connecting block 10 is provided with a fixing groove 11. The left side of the baking oven 1 is installed with a mounting frame 12 to support the telescopic rod 13. The telescopic rod 13 is installed in the mounting frame 12. The telescopic end of the telescopic rod 13 is connected to a wedge block 14. The wedge block 14 is engaged with the fixing groove 11 to fix the connecting block 10. The telescopic end of the telescopic rod 13 is connected to a toggle plate 15. Pulling the toggle plate 15 drives the telescopic end of the telescopic rod 13 to move. The revolving door 9 is connected with a sealing strip 16 to play a sealing role.
[0023] like Figure 1 and Figure 3 As shown, it also includes a first magnet 17 and a second magnet 18. The first magnet 17 is connected to the outside of the oven 1, and the second magnet 18 is connected to the outside of the revolving door 9. The second magnet 18 is magnetically attracted to the first magnet 17, so as to fix the revolving door 9 on the oven 1.
[0024] When the device needs to be used, when the diaphragm 201 needs to be quickly baked, the operator first toggles the toggle rod to move it to the left, and the movement of the toggle rod drives the telescopic end of the telescopic rod 13 to retract, and the retraction of the telescopic end of the telescopic rod 13 drives the wedge block 14 to move to the left, and the wedge block 14 is disengaged from the fixed groove 11, and then the connecting block 10 is pulled to drive the revolving door 9 to rotate ninety degrees counterclockwise, and at the same time the second magnet 18 is disengaged from the first magnet 17, and the operator releases the toggle plate 15 again, so that the telescopic end of the telescopic rod 13 drives the wedge block 14 to move to the right, and then the diaphragm 201 is stretched from the left coiling roller 2 and wound onto the three guide rollers 6, and finally wound onto the right coiling roller 2. After the diaphragm 201 is wound, the operator pulls the connecting block 10 again to drive the revolving door 9 to rotate ninety degrees clockwise. When the revolving door 9 rotates to a certain position, the connecting block 10 and the wedge block 1 4 contacts and squeezes it, so that the wedge block 14 is squeezed to move to the left, and the movement of the wedge block 14 drives the telescopic end of the telescopic rod 13 to move to the left. When the revolving door 9 is completely fitted with the baking oven 1, the connecting block 10 is out of contact with the wedge block 14, so that the telescopic end of the telescopic rod 13 drives the wedge block 14 to move to the right again, so that the wedge block 14 moves to the right into the fixing groove 11, which is convenient for fixing the connecting block 10. At the same time, the second magnet 18 contacts and attracts the first magnet 17, which is convenient for fixing the revolving door 9 on the baking oven 1. The operator turns on the hot air blower 3 again, and the hot air blower 3 generates hot air, so that the hot air is blown into the air outlet frame 5 through the air inlet pipe 4, and the hot air is blown onto the diaphragm 201 from the air outlet frame 5, which is convenient for drying the diaphragm 201. The heating tube 8 is turned on again, and the heating tube 8 generates heat to bake the diaphragm 201, which is convenient for quickly baking the diaphragm 201.
[0025] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
