Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery diaphragm production, in particular to an automatic feeding device for lithium battery diaphragm production. Background Art

[0002] Lithium battery separator is a thin film used to separate the positive and negative electrodes. It can prevent the positive and negative electrodes from short-circuiting while allowing lithium ions to pass inside the battery. Raw material preparation: The main raw materials for lithium battery separators are polymers, such as polypropylene (PP) or polyethylene (PE). These polymers are usually supplied in the form of granules or sheets. Other auxiliary materials, such as conductive agents and additives, are also prepared and screened. Prepare the mixture: According to the specific formula and requirements, the main polymer and auxiliary materials are mixed in a certain proportion. This can be done by melt mixing or solution mixing.

[0003] When mixing existing lithium battery raw materials, the flexibility of the equipment used is poor, the raw materials are mixed unevenly, and the raw materials often contain some impurities that need to be filtered. After mixing, some agglomerated raw materials tend to sink to the bottom of the device during the filtration process, making it difficult to mix evenly, and clogging is prone to occur during the filtration process, affecting the supply of diaphragm raw materials.

[0032] The output shaft of the motor 2 is fixedly connected with a circular rod 501, which penetrates the feeding body 1 and is rotatably connected to the feeding body 1; a stirring rod 502 is penetrated on the surface of the circular rod 501 and is fixedly connected to the circular rod 501; a groove is provided on the left inner wall of the feeding body 1, and a vortex spring 503 is fixedly connected in the groove of the feeding body 1; the end of the vortex spring 503 away from the inner wall of the groove of the feeding body 1 is fixedly connected to a driven rod 504, and the end of the driven rod 504 away from the vortex spring 503 is rotatably connected to the inner wall of the feeding body 1; a connecting plate 505 is fixedly connected to the surface of the driven rod 504; and a ramp block 506 is fixedly connected to the surface of the connecting plate 505; A flip circular plate 507 penetrates the surface of the driven rod 504 and is fixedly connected to the driven rod 504. The starting motor 2 drives the circular rod 501 to rotate, and the circular rod 501 drives the stirring rod 502 to stir and mix the raw materials of the lithium battery diaphragm. The stirring rod 502 at the bottom abuts against the inclined block 506, so that the driven rod 504 rotates and drives the flip circular plate 507 to rotate to flip the raw materials at the bottom of the feeding body 1. Under the action of the volute spring 503, the driven rod 504 is reset to repeatedly abut the inclined block 506, thereby preventing the lithium battery diaphragm raw materials at the bottom of the feeding body 1 from agglomerating during the mixing process, making the mixing more uniform, which is conducive to the subsequent production of lithium battery diaphragms.

[0033] A motor 2 7 is fixedly connected to the bottom of the feeding body 1 , and four anti-skid support legs 8 are fixedly connected to the bottom of the feeding body 1 .

[0037] A feeding pipe 9 passes through the right inner wall of the feeding body 1 and is fixedly connected to the feeding body 1. A feeding pump 10 is fixed on the surface of the feeding pipe 9.

By starting the feeding pump 10, the raw materials automatically enter the feeding pipe 9, which is convenient for automatic feeding.

[0038] Working principle: When feeding the raw materials for lithium battery diaphragm, different raw materials are put into the interior of the feeding body 1 through the feeding port 3, and the motor 2 is turned on. The motor 2 drives the circular rod 501 to rotate, and the circular rod 501 drives the stirring rod 502 to stir and mix the raw materials for lithium battery diaphragm. The stirring rod 502 at the bottom hits the inclined block 506, so that the driven rod 504 rotates and drives the flip circular plate 507 to rotate to flip the raw materials at the bottom of the feeding body 1. Under the action of the volute spring 503, the driven rod 504 is reset to repeatedly hit the inclined block 506, thereby preventing the raw materials for lithium battery diaphragm at the bottom of the feeding body 1 from agglomerating during the mixing process, making the mixing more uniform and effective. To facilitate the subsequent production of lithium battery diaphragms, at the same time, motor 2 7 drives the rotating rod 601 to rotate, and the rotating rod 601 drives the driving block 602 to rotate, and the driving block 602 contacts the inclined sliding block 605, causing the inclined sliding block 605 to slide upward, driving the anti-blocking rod 604 to hit the bottom of the filter screen 4, and the inclined sliding block 605 is reset under the action of the reset spring 606, so that the driving block 602 continuously contacts the inclined sliding block 605, which helps the anti-blocking rod 604 to vibrate and hit the filter screen 4 to prevent the filter screen 4 from being blocked. Finally, the mixed lithium battery diaphragm raw materials enter the bottom inner wall of the feeding body 1, and the raw materials are automatically entered into the feeding pipe 9 by starting the feeding pump 10, which is convenient for automatic feeding.
