DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as: setting, installing, connecting, and connecting should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] Example 1

[0023] A degreasing device for lithium battery diaphragm casting, such as Figure 1-Figure 6 As shown, it includes a base plate 1, a casting roller 2, a connecting frame 3, a rotating ring 4, a scraping frame 5, a connecting ring 6, a first gear 7, a first connecting plate 8, a first motor 9 and a second gear 10. The casting roller 2 is connected to the upper part of the base plate 1, and the connecting frame 3 is connected to the rear side of the base plate 1. The connecting frame 3 is rotatably connected with the rotating ring 4, and the size of the rotating ring 4 is consistent with the size of the contact surface on the connecting frame 3. A scraping frame 5 is connected between the two rotating rings 4, and a scraping blade is provided on the scraping frame 5 to scrape the oil stains on the casting roller 2. The outer side of the rotating ring 4 on the right side is connected to the connecting ring 6, and the connecting ring 6 is connected to the first gear 7. The first connecting plate 8 is connected to the right side of the connecting frame 3 to support the first motor 9. The first motor 9 is installed inside the first connecting plate 8, and the second gear 10 is connected to the output shaft of the first motor 9, and the second gear 10 is meshed with the first gear 7.

[0024] like Figure 5 and Figure 6 As shown, it also includes a second connecting plate 11, a connecting rod 12, a collecting frame 13 and an oil outlet pipe 14. The second connecting plates 11 are symmetrically connected to the outside of the connecting frame 3. The number of the second connecting plates 11 is not less than two. The second connecting plates 11 are connected to the inside of the second connecting plates 11. A collecting frame 13 is connected between the two connecting rods 12 to collect the scraped oil. The oil outlet pipe 14 is connected to the left side of the collecting frame 13.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, it also includes a mounting ring 15, a second motor 16 and a cleaning roller 17. The mounting ring 15 is connected to the connecting frame 3, and the second motor 16 is installed on the left side of the mounting ring 15. The output shaft of the second motor 16 passes through the mounting ring 15 and is connected to the cleaning roller 17 to clean the residual oil in the scraper frame 5.

[0026] When it is necessary to use the device, during the diaphragm casting process, the user places the diaphragm to be cast on the casting roller 2 to facilitate the casting of the diaphragm. Since the diaphragm will be covered with an oil film after casting, the surface of the casting roller 2 will be sticky with oil after long-term use. When the oil on the surface of the casting roller 2 needs to be cleaned, the user starts the first motor 9, and the output shaft of the first motor 9 drives the second gear 10 to rotate. The second gear 10 rotates and contacts the first gear 7 and drives it to rotate. The rotation of the first gear 7 drives the connecting ring 6 to rotate, and the rotation of the connecting ring 6 drives the rotating ring 4 to rotate. The rotating ring 4 drives the scraping frame 5 to rotate, and the scraping frame 5 drives another rotating ring 4 to rotate along the connecting frame 3. During the rotation of the scraping frame 5, the scraping blade on the scraping frame 5 contacts the casting roller 2 and scrapes off the oil on its surface. The scraping frame 5 removes the oil. After scraping, the scraping frame 5 continues to rotate. When the scraping frame 5 rotates to an appropriate angle, the scraping frame 5 pours the oil into the collecting frame 13 to facilitate the collection of the oil. When the oil in the collecting frame 13 is collected to a certain amount, the user puts it in the placement frame under the oil outlet pipe 14, and then the oil flows into the placement frame through the oil outlet pipe 14, which is convenient for collecting the scraped oil. In the process of the scraping frame 5 pouring the oil, there is still oil remaining on the scraping frame 5. When the remaining oil needs to be cleaned, the user starts the second motor 16, and the output shaft of the second motor 16 drives the cleaning roller 17 to rotate. The cleaning roller 17 rotates to contact the inside of the scraping frame 5 and cleans it. Repeat the above operation. When the oil on the casting roller 2 is scraped clean, the first motor 9 and the second motor 16 are turned off to facilitate degreasing the surface of the casting roller 2.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
