Description

Technical Field

[0001] This utility model relates to the field of small lithium battery processing technology, specifically to a small lithium battery processing and drying device. Background Technology

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the positive / negative electrode material and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, the processing, storage, and use of lithium metal require very high environmental standards. With the development of science and technology, lithium batteries have become mainstream. Typically, the electrode plates of a lithium battery need to be dried during the production process.

[0003] In the prior art, patent document CN222048355U discloses a drying device for lithium battery processing. This utility model relates to the field of lithium battery drying technology. The drying device for lithium battery processing is slidably connected to a movable block by a movable groove, and the groove is slidably connected to a movable plate. This facilitates pulling the placement rack out of the drying chamber. The movable block limits the placement rack, preventing it from being completely pulled out of the slide rail. This also optimizes the stability of the placement rack's movement, making it convenient to quickly place or collect lithium batteries, and improving the loading and unloading efficiency of the drying device for lithium battery processing.

[0004] To address the limitations of existing drying devices during drying operations, which can lead to uneven heating of lithium batteries, current technology uses a motor to drive a threaded rod to rotate, which in turn moves a movable block to move the mounting frame. This allows the lithium batteries in various positions on the mounting frame to be heated evenly. However, this method still sometimes fails to provide continuous drying, thus reducing the practicality of the drying device. Utility Model Content

[0027] The present invention will be further described in detail below with reference to embodiments:

[0028] Example 1

[0029] like Figure 1-5As shown, this utility model provides a small lithium battery processing and drying device, including a drying unit 1 and a feeding unit 2 disposed on the outer surface of the drying unit 1 for feeding materials. The drying unit 1 includes a drying component and a transmission component disposed inside it. The feeding unit 2 includes an adjustment component disposed on the outer surface of the drying unit 1 and a pushing component disposed on the outer surface of the adjustment component. The drying component includes a drying chamber 11, a heating chamber 14 fixedly connected to the top of the drying chamber 11, a heating wire 110 detachably connected to the inside of the heating chamber 14, an air pump 17 detachably connected to the top of the heating chamber 14, the output end of the air pump 17 extending into the interior of the heating chamber 14, a connecting pipe 15 fixedly connected to the inner wall of the drying chamber 11, an air jet nozzle 16 disposed on the outer surface of the connecting pipe 15, and one end of the connecting pipe 15 communicating with the interior of the heating chamber 14 through a pipe. The transmission component includes a first transmission belt 12, a second transmission belt 13, a slow motor 18, and a turning roller 19. The connecting ends of the first transmission belt 12 and the second transmission belt 13 are both connected to the drying chamber 11. The inner wall of the drying chamber 11 is rotatably connected, and one side of the slow motor 18 is detachably connected to the outer surface of the drying chamber 11. The drive end of the slow motor 18 is fixedly connected to one end of the turning roller 19, and the other end of the turning roller 19 is rotatably connected to the inner wall of the drying chamber 11. When using a small lithium battery processing drying device, the electrode sheet to be dried is first placed on the outer surface of the transmission belt 12 for transmission. During the transmission process, the heating wire 110 inside the heating chamber 14 is activated, and then the air pump 17 blows air into the heating chamber 14 to heat the air. Finally, the heated air is delivered to the inside of the connecting pipe 15 and sprayed out by the jet nozzle 16 to assist in drying the electrode sheet. When the electrode sheet moves to one side of the transmission belt 12, it will enter the inside of the turning roller 19. By activating the slow motor 18, the turning roller 19 is driven to rotate slowly, so that the electrode sheet can be turned over and enter the transmission belt 23 for reverse transmission and secondary drying. Finally, it is discharged from one side of the transmission belt 23 into the receiving tray 22.

[0030] Example 2

[0031] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the adjustment component includes a support frame 21, one side of which is detachably connected to one side of the drying chamber 11. A receiving tray 22 is detachably connected to the top of the support frame 21. A drive motor 23 is detachably connected to one side of the receiving tray 22. A lead screw 24, which is rotatably connected to the outer surface of the receiving tray 22, is fixedly connected to the drive end of the drive motor 23. A limiting slide rod 26 is detachably connected to the inner side of the top of the lead screw 24. A movable table 25, which is threadedly connected to the outer surface of the lead screw 24, is slidably connected to the outer surface of the limiting slide rod 26. The pushing component includes a hydraulic cylinder 2. 7. The bottom surface of the hydraulic cylinder 27 is detachably connected to the upper surface of the moving table 25. The telescopic end of the hydraulic cylinder 27 is detachably connected to the push plate 29. The upper surface of the push plate 29 is detachably connected to the telescopic limit rod 28, which is detachably connected to the upper surface of the moving table 25. When the electrode sheet enters the outer surface of the receiving tray 22, the hydraulic cylinder 27 can be started, and the telescopic limit rod 28 can be used to drive the push plate 29 to descend, so that it fits against the outer surface of the receiving tray 22. Then, the drive motor 23 is started, which drives the lead screw 24 to rotate, thereby driving the moving table 25 to move under the limit of the limit slide rod 26, so as to transport the electrode sheet to the collection container.

[0032] The working principle of this small lithium battery processing and drying device will be explained in detail below.

[0033] like Figure 1-5 As shown, when using a small lithium battery processing drying device, the electrode sheets to be dried are first placed on the outer surface of the transmission belt 12 for transport. During the transport process, the heating wire 110 inside the heating chamber 14 is activated, and then air is blown into the heating chamber 14 by the air pump 17 to heat the air. Finally, the heated air is delivered to the inside of the connecting pipe 15 and sprayed out by the jet nozzle 16 to assist in drying the electrode sheets. When the electrode sheets move to one side of the transmission belt 12, they enter the inside of the turning roller 19. The turning roller is driven by activating the slow motor 18. Roller 19 rotates slowly, which flips the electrode sheet so that it enters the transmission belt 13 for reverse transmission and secondary drying. Finally, it is discharged from one side of the transmission belt 13 into the receiving tray 22. When the electrode sheet enters the outer surface of the receiving tray 22, the hydraulic cylinder 27 is activated, which, together with the telescopic limit rod 28, drives the pusher plate 29 to descend and make it fit against the outer surface of the receiving tray 22. Then, the drive motor 23 is activated, which drives the lead screw 24 to rotate, thereby driving the moving table 25 to move under the limit of the limit slide rod 26, thus conveying the electrode sheet into the collection container.

[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
