Abstract
Air knife for battery diaphragm flow casting molding, comprise 2-5 level pipe, described pipe is arranged in rear one-level pipe by previous stage pipe and the mode of the concyclic heart is arranged, wherein, the sidewall of every grade of pipe is equipped with air outlet, and the opposite direction of the direction of previous stage pipe air outlet and rear one-level pipe air outlet, in described pipe, one end of first order pipe is provided with air inlet, other end sealing, and the two ends of all the other pipes all seal, the both sides of the air outlet of afterbody pipe are respectively equipped with cutter and bottom knife, and described cutter and bottom knife form air nozzle.The utility model adopts multistage pipe to transmit air, goes out wind resistance little, and wind speed is average, and wind shape is even, can make diaphragm in cooling procedure, obtain the sheet material of even thickness, finally improves diaphragm quality.
Description
Technical field
The utility model relates to the air knife for battery diaphragm flow casting molding.
Background technology
Battery diaphragm is one of interior layer assembly crucial in lithium battery, and the quality of membrane properties determines the characteristic of battery, therefore, obtains excellent barrier film most important.
At present, the production technology of battery diaphragm is divided dry method and the large class of wet method two.Dry production process roughly can be divided into curtain coating section, heat treatment section, stretching pore-forming section.Wherein, flow casting molding is the first step that obtains good barrier film, and air knife is to guarantee that melt extrudes on condensation rollers evenly coolingly from die head, forms one of critical component of flat crystal structure arranged in a uniform.
Yet existing air knife can not well guarantee to obtain in cooling procedure the sheet material of even thickness, thereby make diaphragm structure produce difference, affect final diaphragm quality.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of sheet material that can well guarantee to obtain even thickness in cooling procedure is provided, and finally improves the air knife for battery diaphragm flow casting molding of diaphragm quality.
The utility model solves the technical scheme that its technical problem adopts: for the air knife of battery diaphragm flow casting molding, comprise 2-5 level pipe, described pipe is arranged in rear one-level pipe by previous stage pipe and the mode of the concyclic heart is arranged, wherein, the sidewall of every grade of pipe is equipped with air outlet, and the opposite direction of the direction of previous stage pipe air outlet and rear one-level pipe air outlet, in described pipe, one end of first order pipe is provided with air inlet, other end sealing, and the two ends of all the other pipes all seal, the both sides of the air outlet of afterbody pipe are respectively equipped with cutter and bottom knife, described cutter and bottom knife form air nozzle.
Further, the air outlet of every grade of pipe is narrow slit structure, the length of this narrow slit and pipe equal in length, the width of this narrow slit is the preferred 1.8mm of 0.8-4.0mm().
Further, the air outlet of afterbody pipe is narrow slit structure, the length of this narrow slit and pipe equal in length, the width of this narrow slit is the preferred 1.8mm of 0.8-4.0mm(); The air outlet of all the other pipes is row hole structure.
Further, the shape in hole can be circle, triangle or rectangle etc.
The course of work: the air coming from air blast is in pipeline enters the first order pipe of air knife, by the air outlet in first order pipe, enter second level pipe, then enter step by step rear one-level pipe, through the air outlet of afterbody pipe, enter the air nozzle that cutter and bottom knife form again and blow out, make sheet material evenly cooling.
Research shows, adopts multistage pipe to transmit air, goes out wind resistance little, and wind speed is average, and wind shape is even, can make diaphragm in cooling procedure, obtain the sheet material of even thickness, finally improves diaphragm quality.
