Description

Technical Field

[0001] This utility model relates to the field of continuous extraction transmission technology for wet-process lithium battery separators, and more specifically to a continuous extraction transmission mechanism for wet-process lithium battery separators. Background Technology

[0002] The main function of the continuous extraction transmission mechanism for wet-process lithium battery separators is to drive the separator to operate continuously and stably during the extraction process, ensuring that the separator can pass through the extraction zone evenly, so that the extractant can fully contact the separator, thereby effectively removing impurities from the separator, while avoiding damage to the separator due to unstable transmission, thus ensuring the extraction effect and product quality.

[0003] During the operation of the device, the requirements for the diaphragm's transmission speed and tension may vary at different stages of the actual process. This makes it difficult to flexibly adjust the rotation speed of each roller according to specific process requirements, and it is impossible to accurately ensure the synchronization of operation between each link. This affects the diaphragm extraction effect and quality stability. Moreover, when maintenance or replacement of parts is required, the entire transmission mechanism often needs to be disassembled, which may even affect other normal components connected to it. This not only increases the difficulty and complexity of maintenance, but also consumes a lot of time and manpower. Utility Model Content

[0027] The working principle of this utility model:

[0028] First, place the device horizontally above the ground. Then, the staff will pass the diaphragm coated with the extract through the inlet 106 and wrap it around the guide wheel 205 and the outer wall of the ceramic disc 307 in an S-shaped path. After wrapping, the diaphragm will pass through the outlet 107 to collect the material.

[0029] Next, the device starts working. At this time, the output end of the feed drive 201 drives the buckle 202 and guide wheel 205 to rotate. The rotation of the guide wheel 205 drives the diaphragm coated with the extract liquid to start the transport activity. The electric heating tube 502 starts working, thereby providing heat to the inside of the device and effectively preventing the diaphragm from shrinking and wrinkling excessively during the drying process. The output end of the guide drive 301 drives the drive shaft 305 to rotate. The rotation of the drive shaft 305 drives the roller 306 and ceramic disc 307 to rotate. During the rotation of the ceramic disc 307, the torque sensor 302 records the drive rotation data and transmits it to the PLC controller 105, so that the staff can observe the activity. The setting of the auxiliary limit component 4 can effectively avoid the diaphragm from shifting during the transport process. The ceramic disc 307 and the limit groove 403 help to avoid the risk of slippage during the operation of the device.

[0030] After the device has finished working, the staff can open the front baffle 103 through the handle 104 and clean the inside of the device. When the device is not in use, the feeding component 2 and the intelligent roller splitting drive component 3 can be disassembled for easy maintenance and replacement in the future.
