[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A continuous production lithium-ion battery separator extrusion molding device includes a cutting component 1, a cooling component 2, a base 3, a winding machine 4, an extrusion molding machine 5, and a support leg 6.

[0029] Specifically, such as Figure 4 As shown, the cooling assembly 2 includes a cooling rack 201, which is fixedly connected to the top of the base 3. A second electric telescopic rod 202 is fixedly connected to the top of the cooling rack 201, and a connecting block 203 is fixedly connected to the bottom of the second electric telescopic rod 202. An adjusting plate 204 is fixedly connected to the bottom of the connecting block 203.

[0030] Specifically, such as Figure 4 As shown, the cooling rack 201 has fixed plates 205 on both sides inside, and the base 3 has a cooler 206 fixedly connected to the bottom.

[0031] Specifically, such as Figure 4 As shown, a dustproof plate 207 is fixedly connected to the top of the adjusting plate 204, and sliders 208 are fixedly connected to both sides of the adjusting plate 204. Rotating parts 209 are fixedly connected to the opposite side of the adjusting plate 204 and the fixed plate 205.

[0032] In this embodiment: the cooling rack 201 connects to the second electric telescopic rod 202, which in turn connects to and adjusts the connecting block 203. The connecting block 203 supports the adjusting plate 204. The adjusting plate 204, in conjunction with the fixing plate 205 and the rotating component 209, clamps and limits the lithium-ion battery separator. The rotating component 209 is an existing rotating component with a built-in crossbar, so that the lithium-ion battery separator will not be unable to be pulled during the winding process. The cooling device 206 is an existing air conditioning device that releases cold air to quickly cool the lithium-ion battery separator. The dustproof plate 207 can provide ventilation for the cooling device 206. The slider 208 can limit the movement of the adjusting plate 204.

[0033] Specifically, such as Figure 5 As shown, a fixed frame 7 is fixedly connected to the top of the base 3, a rotating column 8 is rotatably connected inside the fixed frame 7, and a motor 9 is fixedly connected to the right side of the rotating column 8.

[0034] Specifically, such as Figure 5 As shown, a third electric telescopic rod 10 is fixedly connected to the bottom of the base 3, and an adjustment frame 11 is fixedly connected to the top of the third electric telescopic rod 10. A pressure column 12 is rotatably connected inside the adjustment frame 11.

[0035] In this embodiment: the fixed frame 7 can achieve the effect of rotating the rotating column 8; the motor 9 can drive the rotating column 8 to rotate; the third electric telescopic rod 10 can achieve the effect of connecting and adjusting the adjusting frame 11; the adjusting frame 11 can achieve the effect of rotating the pressing column 12; the pressing column 12 and the rotating column 8 are both provided with anti-slip coatings, so as to limit the lithium-ion battery separator when cutting the lithium-ion battery separator.

[0036] Specifically, such as Figure 3 As shown, the top of the connecting plate 107 is provided with a slot 13, and the inner wall of the slot 13 is engaged with the bottom of the plate 106.

[0037] Specifically, such as Figure 4 As shown, the cooling rack 201 has grooves 14 on both sides, and the inner wall of the grooves 14 is slidably connected to the surface of the slider 208.

[0038] In this embodiment: the slot 13 can be used to fix the card plate 106, and the slide 14 can be used to limit the sliding connection of the slider 208.

[0039] Working principle: First, the material for making lithium-ion battery separators is extruded from the extruder and guided into the extrusion molding machine 5. The extrusion molding machine 5 then extrudes and shapes the lithium-ion battery separator, which is discharged through the front outlet. The shaped lithium-ion battery separator is then guided between the opposing sides of two rotating parts 209, passes between the rotating column 8 and the pressing column 12, and then passes between the rotating rod 104 and the cutter 105, connecting to the winding machine 4. The third electric telescopic rod 10 can then be opened, causing the adjusting frame 11 to adjust the pressing column 12, thus clamping the lithium-ion battery separator between the pressing column 12 and the rotating column 8. Then, the second electric telescopic rod 202 is opened, causing the connecting block 203 and the adjusting plate 204 to adjust downwards, thus clamping the lithium-ion battery separator with the rotating part 209. Hold the limit switch, then open the cooler 206, which releases cooling gas to cool the lithium-ion battery separator. Then, open the winding machine 4 and the motor 9, so that the winding machine 4 can wind up the lithium-ion battery separator. The motor 9 drives the rotating column 8 and the pressing column 12 to transport the lithium-ion battery separator. During the transport process, the tension of the lithium-ion battery separator can be adjusted by opening the first electric telescopic rod 101 to raise and lower the rotating rod 104, so that the lithium-ion battery separator is always kept taut, thus avoiding wrinkles in the lithium-ion battery separator during the winding process. Finally, after collecting a certain amount of lithium-ion battery separator, the motor 9 and the winding machine 4 can be stopped. Then, the lithium-ion battery separator can be adjusted downward by rotating the rod 104, so that the lithium-ion battery separator can be cut by the cutter 105.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
