[0034] Two lifting brackets 5 are respectively connected to the two ends of each de-oiling pressure roller 3, wherein two of the lifting brackets 5 are arranged vertically and the other two of the lifting brackets 5 are arranged obliquely. Each of the lifting brackets 5 is installed on the frame 6, and the lifting bracket 5 can drive the de-oiling pressure roller 3 to move radially along the casting roller 1, so as to adjust the tightness of the de-oiling pressure roller 3 pressing the casting roller 1.

[0035] Recombination Figure 3 and 4 As shown, each lifting bracket 5 is arranged on one side of the de-oiling pressure roller 3, and the lifting bracket 5 includes a fixed frame 9, a cylinder 10, a slider 11 and a driving mechanism. The cylinder 10 is installed on the fixed frame 9, and the cylinder 10 can be extended and retracted along the radial direction of the casting roller 1. The output end of the cylinder 10 is connected to the slider 11. The slider 11 is slidably connected to the fixed frame 9. Here, the inner side of the fixed frame 9 is provided with a slide rail 16 extending along the radial direction of the casting roller 1, and the outer side of the slider 11 is slidably connected to the slide rail 16. The cylinder 10 can drive the slider 11 to slide along the radial direction of the casting roller 1, so that the de-oiling pressure roller 3 is close to or away from the casting roller 1.

[0036] The driving mechanism is mounted on the slider 11 and connected to one end of the de-oiling pressure roller 3. The driving mechanism specifically comprises a motor 12 and a gear set, wherein the motor 12 is connected to the gear set, and the gear set is connected to one end of the de-oiling pressure roller 3.

[0037] More specifically, the gear set includes a driving gear 13 and a driven gear 14 meshing with each other, the motor 12 is mounted on the fixing frame 9 and connected to the driving gear 13, a baffle 15 is provided on one side of the fixing frame 9, the motor 12 is mounted on the back of the baffle 15, and the output shaft of the motor 12 passes through the baffle 15 and is connected to the driving gear 13.

[0038] In order to facilitate the installation of the lifting bracket 5 on the frame 6, the lifting bracket 5 further includes a base 17, and the base 17 is a rectangle or a right triangle. Figure 1 As shown, the lifting brackets 5 at both ends of the two oil removal rollers 3 are installed on the rectangular base 8 on the frame 6. In order to realize the installation of the vertically arranged lifting brackets 5, the base 17 is rectangular, and the base 17 is supported on the upper surface of the base 8 and fixedly connected to the base 8. Figure 5 As shown, in order to realize the installation of the inclined lifting bracket 5, when the base 17 is a right-angled triangle, one of its right-angled sides is vertically arranged and fits and is fixedly connected to the side of the base 8, and a plurality of oblong mounting holes 18 are arranged on the hypotenuse of the base 17. A plurality of bolt holes are arranged at the bottom of the fixing frame 9, and each of the bolt holes is aligned with a mounting hole 18 and is locked by bolts.

[0039] The air blowing pipe 4 is installed on the frame 6 and is close to one side of the oil removal pressure roller 3 of the contact roller 2. The air blowing pipe 4 can blow air axially along the oil removal pressure roller 3. When the casting roller 1 rotates, the oil removal pressure roller 3 close to the contact roller 2 will first contact the accumulated oil on the surface of the casting roller 1 and scrape off the accumulated oil. The air blowing pipe 4 blows the scraped accumulated oil to the other side of the oil removal pressure roller 3.

[0040] In addition, in order to receive the accumulated oil being blown off, the deoiling device for the casting roll 1 of the lithium battery diaphragm casting sheet further includes an oil receiving pan 7, which is mounted on the frame 6 and is located below the casting roll 1. The oil receiving pan 7 is approximately rectangular, so that the accumulated oil falling from the surface of the casting roll 1 can all fall into the oil receiving pan 7.

[0041] When the casting roller 1 oil removal device of the lithium battery diaphragm casting sheet is working, when the sheet reaches the right side of the casting roller 1, it begins to gradually separate from the casting roller 1. When the sheet separates from the casting roller 1, a large amount of white oil accumulates on the surface of the casting roller 1. The casting roller 1 first contacts the first oil removal pressure roller 3 close to the contact roller 2. The first oil removal pressure roller 3 scrapes off the accumulated oil on the surface of the casting roller 1, and the air pipe 4 blows the scraped accumulated oil to the other side of the first oil removal pressure roller 3 and drops it to the oil receiving pan 7; then the casting roller 1 contacts the second oil removal pressure roller 3, and the second oil removal pressure roller 3 continues to scrape off the remaining small amount of accumulated oil on the surface of the casting roller 1. In this way, all the accumulated oil on the surface of the casting roller 1 is removed, which can effectively reduce the frequency of manual wiping. And the cylinder 10 can be used to adjust the tightness of the oil removal pressure roller 3 on the casting roller 1 to improve the scraping efficiency. When the casting roller 1 needs to be cleaned after long-term use, the cylinder 10 drives the oil removal pressure roller 3 away from the casting roller 1 so that the surface of the casting roller 1 is completely cleaned.
