Description

Technical Field

[0001] This application relates to the technical field of casting roll degreasing components, and in particular to a casting roll degreasing device for lithium battery separator production. Background Technology

[0002] With the rapid development of the new energy vehicle market, the demand for lithium-ion batteries has increased dramatically. To improve the performance and safety of lithium batteries, the quality requirements for lithium battery separators are becoming increasingly stringent. Casting is a crucial step in the production process of lithium battery separators. In the wet-process separator casting process, plastic film casting equipment extrudes molten plastic material through a narrow die slit and onto the surface of the casting roller for cooling and shaping. The shaped base film contains a large amount of paraffin oil and other oil solvents. After the base film comes into contact with the release roller, these oil solvents are transferred, leaving a large amount of paraffin oil and other oil solvents adsorbed on the casting roller. The casting roller is a key piece of equipment in the casting process, mainly used to manufacture films, sheets, and other thin materials. Casting is a process in which molten polymer is extruded through a narrow die and rapidly cooled and solidified on a cooling roller.

[0003] The existing publication number is CN217346589U, entitled "An Oil Removal Adsorption Device and a Casting Roll Oil Removal Equipment." The oil removal adsorption device includes a housing and an oil scraping element; the housing has an inner cavity for creating a negative pressure environment; the oil scraping element has at least one working surface, the side of which is used to contact the surface of the workpiece to be degreased; an oil suction hole penetrating the oil scraping element and communicating with the inner cavity is provided on the working surface, and the working surface is recessed. The oil removal adsorption device of this application has a good adsorption and degreasing effect on the oil on the surface of the workpiece to be degreased, and compared with existing oil removal devices, it can effectively improve the oil removal effect on the surface of the workpiece to be degreased.

[0004] Regarding the aforementioned technologies, the inventors have discovered that the above-mentioned casting roll degreasing utilizes an oil scraping element and an oil removal adsorption device to remove oil stains from the casting roll. However, during the above-mentioned casting roll degreasing, the oil stains are removed by the oil scraping element and the oil removal adsorption device, but the oil stains adhere to the oil scraping element and the oil removal adsorption device, which requires manual cleaning later, increasing the steps and making the casting roll degreasing and cleaning inconvenient. Utility Model Content

[0005] In order to overcome the problem that existing casting roll degreasing methods use scraping elements and oil adsorption devices to remove oil stains from casting rolls, but the oil stains are removed by the scraping elements and oil adsorption devices during the above-mentioned casting roll degreasing process, the oil stains adhere to the scraping elements and oil adsorption devices, resulting in the need for manual cleaning later, which increases the steps and makes casting roll degreasing and cleaning inconvenient, this application provides a casting roll degreasing device for lithium battery separator production.

[0006] The oil removal device for casting rollers used in lithium battery separator production provided in this application adopts the following technical solution:

[0007] A degreasing device for casting rollers used in lithium battery separator production includes a cleaning component, a clamping component, and a filter component. The cleaning component includes a liquid storage cylinder with an opening at the top and a cleaning liquid inside. A rotating frame is vertically rotatably connected inside the liquid storage cylinder, and the bottom end of the rotating frame vertically penetrates the bottom surface of the liquid storage cylinder. A rotating motor is vertically fixed on the bottom surface of the liquid storage cylinder, and the output end of the rotating motor is fixed to the bottom end surface of the rotating frame. Brush strips and scraper strips are symmetrically and vertically fixed on the vertical end surface inside the rotating frame. A drain pipe is vertically connected and fixed on the bottom surface of the liquid storage cylinder, and a filter component is vertically assembled at the bottom end of the drain pipe. A guide frame is vertically fixed on one side of the top of the outer circumference of the liquid storage cylinder, and a clamping component is vertically slidably assembled on the guide frame.

[0008] By adopting the above technical solution, the top of the casting roller requiring degreasing is vertically inserted into the clamping device during use. Then, the clamping device holds the casting roller and slides it vertically down on the guide frame, driving the clamped casting roller into the interior of the liquid storage tank. The rotating motor on the bottom surface of the liquid storage tank is started to drive the rotating frame to rotate in the liquid storage tank. The brush strips and scraper strips on the inner wall of the rotating frame are in close contact with the outer wall of the casting roller, scraping and washing away the oil stains on the outer wall of the casting roller. The oil stains remain in the cleaning liquid. After cleaning, the casting roller is moved on the guide frame by the clamping device, and the cleaned casting roller is pulled out of the liquid storage tank. In order to ensure that the oil stains in the cleaning liquid are removed, the cleaning liquid is discharged from the drain pipe. The cleaning liquid is filtered through the filter to remove the oil stains in the cleaning liquid, avoiding the pollution of the environment by the oil stains in the discharged cleaning liquid. This ensures that the oil stains remain in the cleaning liquid, and no manual cleaning is required later, reducing the steps and increasing the convenience of degreasing and cleaning the casting roller.

[0009] Optionally, the clamping component includes a sleeve frame, which is vertically slidably mounted on the guide frame, and a bracket is fixed on the vertical end face of the sleeve frame near the liquid storage cylinder, with a clamping cylinder vertically fixed at the end of the bracket.

[0010] By adopting the above technical solution, the top of the casting roller is inserted into the clamping cylinder, and the sleeve at the end of the support on the clamping cylinder slides vertically on the guide frame, vertically pulling the casting roller to move vertically in the liquid storage cylinder.

[0011] Optionally, a screw seat is symmetrically and horizontally fixed on the outer circumference of the clamp, and a clamping screw is assembled through the horizontal thread in the screw seat.

[0012] By adopting the above technical solution, the clamping screws on both sides of the rotating clamping cylinder are used to press and hold the ends of the casting roller to remain stable.

[0013] Optionally, a lifting motor is vertically fixed on the top surface of the guide frame, and a lifting screw is vertically fixed at the output end of the lifting motor. A screw hole strip is horizontally fixed on the other end surface of the sleeve frame, and the screw hole strip and the lifting screw are threadedly connected and assembled.

[0014] By adopting the above technical solution, when the vertically lifting casting roller moves vertically in the liquid storage tank, the lifting motor is started to drive the lifting screw to rotate, and the screw hole strip on one side of the drive sleeve is threaded through and assembled with the lifting screw, which facilitates the vertical sliding of the vertical drive sleeve on the guide frame, and the vertically lifting casting roller moves vertically in the liquid storage tank.

[0015] Optionally, a valve is connected and fixed to the drain pipe, and a screw cap is vertically connected and fixed to the bottom end of the drain pipe.

[0016] By adopting the above technical solution, the valve on the drain pipe is opened when draining the liquid, and the screw cap at the bottom of the drain pipe is threaded onto the filter cartridge to filter and clean the oil stains in the drained cleaning liquid.

[0017] Optionally, the filter element includes a filter cartridge with an opening at the top and a liquid drain pipe vertically connected and fixed on the bottom surface of the filter cartridge. The upper side of the inner wall of the filter cartridge has an internal thread that is compatible with the thread of the screw cap.

[0018] By adopting the above technical solution, the internal thread at the top of the filter cartridge is matched with the thread of the screw cap, connecting the assembled filter cartridge and the drain pipe to receive the cleaning liquid for filtration.

[0019] Optionally, a perforated ring is horizontally fixed on the upper side of the inner wall of the filter cartridge, and a screen is vertically inserted inside the filter cartridge. A plug ring is horizontally fixed at the top of the screen, and the plug ring is inserted into the perforated ring. Oil filter cotton is fixed on the inner wall of the screen.

[0020] By adopting the above technical solution, the screen cylinder is inserted into the interior of the filter cylinder, and the insertion ring at the top of the screen cylinder is inserted into the perforated ring to support the screen cylinder and keep it stable. The oil in the discharged cleaning fluid is filtered and removed by the oil filter cotton, thus avoiding the pollution of the environment by the oil in the discharged cleaning fluid.

[0021] Optionally, a transducer is fixed to the bottom of the outer circumference of the liquid storage cylinder through the inner wall, and an ultrasonic generator is fixed to the outer end of the transducer.

[0022] By adopting the above technical solution, in order to ensure the effectiveness of the cleaning fluid in the storage tank in cleaning the oil stains on the casting roller, an ultrasonic generator is started to generate a high-frequency electrical signal, and the electrical signal is converted into mechanical vibration through a transducer. The high-frequency electrical signal is converted into high-frequency mechanical vibration and transmitted to the liquid medium in the storage tank to clean the impurities on the surface of the casting roller.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] In use, the top of the casting roller requiring degreasing is vertically inserted into the clamping device. The clamping device then holds the casting roller and slides it vertically down the guide frame, causing the cast roller to be inserted into the inside of the liquid storage tank. The rotating motor on the bottom of the liquid storage tank is started, causing the rotating frame to rotate inside the liquid storage tank. The brush and scraper strips on the inner wall of the rotating frame are in close contact with the outer wall of the casting roller, scraping and washing away the oil stains on the outer wall of the casting roller. The oil stains remain in the cleaning liquid. After cleaning, the casting roller is moved up the guide frame by the clamping device, and the cleaned casting roller is pulled out of the liquid storage tank. In order to ensure that the oil stains in the cleaning liquid are removed, the cleaning liquid is discharged from the drain pipe. The cleaning liquid is filtered through the filter to remove the oil stains in the cleaning liquid, avoiding the pollution of the environment by the oil stains in the discharged cleaning liquid. This ensures that the oil stains remain in the cleaning liquid, eliminating the need for manual cleaning later, reducing steps and increasing the convenience of degreasing and cleaning the casting roller.
