Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery separator casting sheet processing, and specifically relates to an oil removal device for lithium battery separator casting sheets. Background Art

[0002] A lithium battery separator is a thin film located between the positive and negative electrodes, used to isolate the positive and negative electrodes, prevent short circuits, and prevent direct contact between ions in the electrolyte. During the production and processing of lithium battery separator casting sheets, an oil film will adhere to the surface of the lithium battery separator casting sheets. In order to improve the quality of lithium battery separator casting sheets, it is necessary to remove the oil from their surfaces. Therefore, an oil removal device for lithium battery separator casting sheets is required. However, the current oil removal devices for lithium battery separator casting sheets still have the following deficiencies:

[0003] For example, the patent document with the application number 202220197294.1 discloses an oil removal device for lithium battery separator casting sheets. In this oil removal device for lithium battery separator casting sheets, multiple oil holes suck the white oil adsorbed by the shaft sleeve under negative pressure. The white oil passes through the oil holes, the hollow cavity, and the first pipeline and is recycled to the oil collection cavity, thereby realizing the collection of the white oil on the surface of the lithium battery separator casting sheet and achieving the oil removal of the surface of the lithium battery separator casting sheet by the shaft sleeve, avoiding manual oil removal of the surface of the lithium battery separator casting sheet. However, a large amount of residue will be left when the oil on its surface is treated by suction, thus affecting the overall oil removal efficiency.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and an oil removal device for lithium battery separator casting sheets is proposed. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following further describes the embodiments of the present utility model in detail in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0023] As Figures 1 to 4As shown in the figure, an oil removal device for lithium battery separator casting sheets includes an operating table 1 and an oil scraping assembly 3. A unwinding roller 2 is installed at the rear side of the upper surface of the operating table 1. The oil scraping assembly 3 is arranged on the upper surface of the operating table 1, and the oil scraping assembly 3 includes an oil receiving tank 301, a fixed oil scraping plate 302, a support plate 303, a support top plate 304, an electric push rod 305, a movable oil scraping plate 306 and a limit sliding groove 307. The oil receiving tank 301 is opened at the rear side of the upper surface of the operating table 1, and a fixed oil scraping plate 302 is installed inside the oil receiving tank 301. A support plate 303 is arranged at the rear end of the upper surface of the operating table 1, and two groups of support plates 303 are symmetrically arranged. A support top plate 304 is installed on the top of the support plate 303. An electric push rod 305 is arranged on the upper surface of the support top plate 304, and a movable oil scraping plate 306 is installed at the bottom of the electric push rod 305.

[0024] The specific operation is as follows. When in use, the diaphragm casting sheet roll is pulled out from the unwinding roller 2 and passes through above the fixed oil scraping plate 302. The electric push rod 305 is started, so that the electric push rod 305 drives the movable oil scraping plate 306 to move downward. The two ends of the movable oil scraping plate 306 are slidably connected to the inside of the limit sliding groove 307, which plays a role in limiting the movement of the movable oil scraping plate 306. The movable oil scraping plate 306 descends until its lower surface fits with the lower surface of the fixed oil scraping plate 302 and the surface of the casting sheet. During the winding process, the oil on the surface of the casting sheet is scraped off by the fixed oil scraping plate 302 and the movable oil scraping plate 306 and falls into the oil receiving tank 301.

[0025] Please refer to Figure 1 and Figure 3 On the inner surface of the support plate 303, a limit sliding groove 307 is opened, and the inside of the limit sliding groove 307 is slidably connected to the upper ends of both sides of the movable oil scraping plate 306. In the middle section of the upper surface of the operating table 1, an oil dripping groove 4 is opened, and a lower oil groove 5 is opened on the rear surface inside the oil dripping groove 4. The rear end of the lower oil groove 5 penetrates through the front surface of the oil receiving tank 301, and an oil discharge valve 6 is arranged at the lower end of the outer surface on the right side of the oil receiving tank 301. At the upper end of the rear surface of the operating table 1, a fixing plate 9 is installed, and a servo motor 10 is arranged on the front surface of the fixing plate 9. And the output end of the servo motor 10 is connected to a winding roller 11 through a coupling. Auxiliary rollers 12 are arranged at the front end on the upper side of the oil receiving tank 301 and at the rear end on the upper side of the waste water tank 801, and a drain valve 13 is arranged on the right surface of the waste water tank 801;

[0026] The specific operation is as follows. When in use, the servo motor 10 is started, so that the servo motor 10 drives the winding roller 11 to automatically wind the oil-removed casting sheet. During the winding process, the oil-scraped part of the casting sheet drips into the oil dripping groove 4 when passing through the oil dripping groove 4 and flows into the oil receiving tank 301 through the lower oil groove 5 for unified recovery. After the oil removal is completed, the oil discharge valve 6 is opened to discharge the oil, and the drain valve 13 can discharge the waste water generated during the cleaning process through the drain valve 13.

[0027] Please refer to Figure 4, a support frame 7 is installed on the upper surface of the front end of the operating table 1, and a cleaning assembly 8 for cleaning the cast sheet is arranged on the surface of the operating table 1. The cleaning assembly 8 includes a waste water tank 801, a water pump 802, a water delivery pipe 803, and a tee connection pipe 804. The waste water tank 801 is opened on the upper surface of the operating table 1. The water pump 802 is installed at the front end of the left side of the operating table 1, and the front end of the water pump 802 is connected with the water delivery pipe 803. The water outlet end of the water delivery pipe 803 is provided with the tee connection pipe 804, and the upper end of the tee connection pipe 804 penetrates through the upper surface of the support frame 7 and extends to the lower part of the support frame 7. The cleaning assembly 8 further includes a water collecting pipe 805, a water spray head 806, and a water absorption roller 807. The water outlet of the upper end of the tee connection pipe 804 is installed with the water collecting pipe 805. The lower end of the tee connection pipe 804 penetrates through the left surface of the operating table 1 and extends into the interior of the waste water tank 801. The upper surface of the lower end of the tee connection pipe 804 and the lower surface of the water collecting pipe 805 are both installed with the water spray head 806. The water absorption roller 807 is arranged on the front side of the upper surface of the operating table 1;

[0028] The specific operation is as follows. When in use, the cast sheet passes through below the water collecting pipe 805. The water pump 802 is started, so that the water pumped by the water pump 802 is conveyed into the tee connection pipe 804 through the water delivery pipe 803, and then conveyed into the water collecting pipe 805 through the upper side of the tee connection pipe 804. Then, the water is sprayed on the surface of the cast sheet through the lower end of the tee connection pipe 804 and the water collecting pipe 805 through the water spray head 806 to wash it. After washing, the cast sheet passes through the inner side of the water absorption roller 807, and the water is quickly sucked dry during the winding process.

[0029] In summary, as Figures 1 to 4As shown, when the oil removal device for lithium battery separator casting sheet is in use, first, the separator casting sheet roll is pulled out from the unwinding roller 2 and passes above the fixed oil scraping plate 302. Subsequently, the servo motor 10 is started, so that the servo motor 10 drives the winding roller 11 to automatically wind the degreased casting sheet. Then, the electric push rod 305 is started, so that the electric push rod 305 drives the movable oil scraping plate 306 to move downward. Since both ends of the movable oil scraping plate 306 are slidably connected to the inner side of the limit chute 307, it plays a role in limiting the movement of the movable oil scraping plate 306. The movable oil scraping plate 306 descends until its lower surface, the lower surface of the fixed oil scraping plate 302 and the surface of the casting sheet are in contact. During the winding process, the oil on the surface of the casting sheet is scraped off by the fixed oil scraping plate 302 and the movable oil scraping plate 306 and falls into the oil receiving tank 301. During the winding process, the oil-scraped part of the casting sheet drips into the drip oil tank 4 when passing through the drip oil tank 4, and flows into the oil receiving tank 301 through the lower oil tank 5 for unified recovery. After the oil removal is completed, the drain valve 6 can be opened to drain the oil. The casting sheet passes under the water collecting pipe 805. The water pump 802 is started, so that the water pumped by the water pump 802 is conveyed into the three-way connecting pipe 804 through the water delivery pipe 803, and then conveyed to the water collecting pipe 805 through the upper side of the three-way connecting pipe 804. Then, water is sprayed on the surface of the casting sheet through the lower end of the three-way connecting pipe 804 and the water collecting pipe 805 through the spray head 806 for rinsing. After rinsing, the casting sheet passes through the inside of the water absorption roller 807, and the water is quickly sucked dry during the winding process. After the operation is completed, the drain valve 13 can be opened to discharge the wastewater generated during the cleaning process through the drain valve 13.
