DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Reference Figure 1-Figure 4As shown, an automatic roll-changing and edge-winding machine for waste lithium battery diaphragms comprises: a fixed bottom plate 1, a fixed side plate 2 is fixedly connected to the top of the fixed bottom plate 1, a plurality of rotating rods 5 are rotatably provided on the fixed side plate 2, a winding roller 6 is fixedly sleeved on each rotating rod 5, and a limiting plate 7 is fixedly connected to the front and rear sides of each winding roller 6, and the limiting plate 7 is used to limit the position of the waste, and a transmission structure is provided on the fixed side plate 2 to bypass the waste from each winding roller 6 and finally fix the waste on the last winding roller 6; a roll-changing structure comprises a mounting plate 3 fixedly connected to the side wall of the fixed side plate 2, and a sliding plate 3 is provided on the mounting plate 3 A fixed rod 9 corresponding to each winding roller 6 is dynamically provided, each fixed rod 9 penetrates the mounting plate 3 and extends to the bottom of the mounting plate 3, a push block 15 is fixedly connected to the top of each mounting plate 3, a fixed block 8 is fixedly connected to the bottom of each fixed rod 9, a fixed spring 10 is provided on each fixed block 8, and a cutting structure is provided on the side wall of each push block 15. As the winding progresses, the amount of waste on the winding roller 6 increases, and the thickness of the waste winding increases accordingly. The bottom end of the waste contacts the push block 15, thereby pushing the push block 15 to move downward, driving the fixed rod 9 and the fixed block 8 to move accordingly. The fixed spring 10 is stretched, and as the pushing block 15 moves, the cutting structure will cut off the waste material and automatically change the roll; the cutting structure includes a cutting knife 16 slidably connected to the side wall of the pushing block 15, and each cutting knife 16 is fixedly connected to a moving block 17 on the side wall, and each pushing block 15 is provided with a moving groove 18 corresponding to the moving block 17 on the side wall, and each cutting knife 16 is fixedly connected to a connecting plate 20 at the bottom end, and a plurality of fixed blocks 11 are fixedly connected to the top of the mounting plate 3, and the position of each fixed block 11 corresponds to the connecting plate 20, and the bottom end of each moving block 17 is fixedly connected to The connecting spring 19, one end of each connecting spring 19 away from the moving block 17 is fixedly connected to the inner wall of the moving groove 18, and the top of the cutting knife 16 is arranged below the top of the pushing block 15. As the pushing block 15 moves, the cutting knife 16 moves accordingly, causing the connecting plate 20 to move downward together, and finally the connecting plate 20 contacts the fixed block 11 on the mounting plate 3, and the continued movement of the pushing block 15 allows the fixed block 11 to hold the connecting plate 20, so that the connecting plate 20 and the cutting knife 16 move upward relative to the pushing block 15, allowing the cutting knife 16 to move to the top of the pushing block 15 to cut off the waste.

[0021] A pressing block 13 is slidably connected between each two corresponding limiting plates 7, and a sliding block is fixedly connected to the side wall of each pressing block 13. A sliding groove 12 corresponding to the sliding block is opened on the side wall of each limiting plate 7, and each sliding groove 12 extends to the part of the limiting plate 7 located on the inner side of the winding roller 6. A pressing spring 14 is fixedly connected to the bottom end of each sliding block, and one end of each pressing spring 14 away from the sliding block is fixedly connected to the inner wall of the corresponding sliding groove 12. The elastic coefficient of the pressing spring 14 at each winding roller 6 is different, and the elastic coefficient of the pressing spring 14 closer to the end is larger. The larger the pressure block 13 is, the greater the force exerted by the pressing block 13 on the waste, the greater the friction between the pressing block 13 and the waste, and the pressing block 13 is pulled outward. Therefore, when the winding roller 6 is winding, the outer winding roller 6 can pull the waste to reel in, so that the pressing spring 14 contracts, and the waste passes through between each pressing block 13, and the waste is pulled onto the outermost pressing block 13, and the pressing block 13 is released. The elastic force of the pressing spring 14 causes the pressing block 13 to press the waste, and the friction between the pressing block 13 and the waste fixes the waste. As the winding roller 6 is wound, the friction pulls the waste to be reeled onto the winding roller 6.

[0022] Each pressing block 13 is arranged in an arc shape and matches the winding roller 6 , and the side wall of each pressing block 13 is frosted to facilitate the pressing block 13 to press the waste material onto the winding roller 6 .

[0023] The transmission structure includes a support plate 23 fixedly connected to the side wall of the fixed side plate 2 away from the mounting plate 3. The top of the support plate 23 is fixedly connected to a motor 4, and the position of the motor 4 corresponds to one of the rotating rods 5. Each rotating rod 5 penetrates the fixed side plate 2 and extends to the other side of the fixed side plate 2. The end of the rotating rod 5 corresponding to the motor 4 is fixedly connected to the output end of the motor 4. A rotating gear 21 is fixedly sleeved on each rotating rod 5. Multiple rotating gears 21 are connected to each other through a transmission tooth chain 22. After the motor 4 is started, its output end drives the corresponding rotating rod 5 to rotate. Under the action of the rotating gear 21 and the transmission tooth chain 22, the remaining multiple rotating rods 5 all rotate.

[0024] Each fixing spring 10 is respectively sleeved on the outer wall of the corresponding fixing rod 9, the bottom end of each fixing spring 10 is respectively fixedly connected to the corresponding fixing block 8, and the top end of each fixing spring 10 is fixedly connected to the bottom end of the mounting plate 3, so that the fixing spring 10 can play an effect.

[0025] A plurality of fixing bolts are arranged on the fixed base plate 1, the fixed side plate 2 and the mounting plate 3, and the fixed base plate 1, the fixed side plate 2 and the mounting plate 3 are fixedly connected by fixing bolts, so that the fixing of the fixed base plate 1, the fixed side plate 2 and the mounting plate 3 is more firmly secured; the fixing block 8 and the fixing rod 9 as well as the fixing rod 9 and the pushing block 15 are all fixedly connected by threads, so that the disassembly of the fixing block 8 and the pushing block 15 is more convenient.

[0026] When the present invention is used, the diaphragm waste is first passed through each pressing block 13, and the waste is pulled onto the outermost pressing block 13, and the pressing block 13 is released. The elastic force of the pressing spring 14 causes the pressing block 13 to press the waste, and the friction between the pressing block 13 and the waste fixes the waste, and then the motor 4 is started. After the motor 4 is started, its output end drives the corresponding rotating rod 5 to rotate, and under the action of the rotating gear 21 and the transmission gear chain 22, the remaining multiple rotating rods 5 all rotate, driving the winding roller 6 fixedly mounted on the rotating rod 5 to rotate together, and the waste is wound onto the winding roller 6; as the winding proceeds, the amount of waste on the winding roller 6 at the end increases, and the thickness of the waste winding increases with the increase in the thickness of the waste winding. As the amount of waste increases, the bottom end of the waste contacts the pushing block 15, thereby pushing the pushing block 15 to move downward, driving the fixing rod 9 and the fixing block 8 to move accordingly, causing the fixing spring 10 to stretch. As the pushing block 15 moves, the cutting knife 16 moves accordingly, causing the connecting plate 20 to move downward together, and finally the connecting plate 20 contacts the fixed block 11 on the mounting plate 3. The continued movement of the pushing block 15 allows the fixed block 11 to hold the connecting plate 20, causing the connecting plate 20 and the cutting knife 16 to move upward relative to the pushing block 15, allowing the cutting knife 16 to move to the top of the pushing block 15, cutting off the waste, and automatically changing the roll. The adjacent winding roller 6 performs the winding work of the waste.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
