DETAILED DESCRIPTION

[0018] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0019] An automatic winding machine for copper foil, such as Figure 1-Figure 5As shown, it includes a workbench 1, a fixed plate 2, a fixed tripod 3, a large rotating wheel 4, a small rotating wheel 5, an adjusting plate 6, a connecting block 7, a fixing rod 8, a first sliding block 811, a first sliding rod 812, a first spring 813, a T-plate 9, a rubber disc 25, a second spring 10, a first rotating motor 11, a belt 111, a second rotating motor 12, a first transmission rod 13, a driving bevel gear 14, a driven bevel gear 15, a second transmission rod 16, a cam 17, a fixing block 23 and a hexagonal bolt 24. The upper left part of the workbench 1 is fixedly connected to the fixing plate 2, the right part of the fixing plate 2 is rotatably connected to the fixing tripod 3, the right part of the fixing tripod 3 is fixedly connected to the large rotating wheel 4, the center part of the large rotating wheel 4 is rotatably connected to the small rotating wheel 5, and the large rotating wheel 4 is evenly distributed with four sliding grooves in an annular shape. The groove is provided with an adjusting plate 6 in a sliding manner, and an anti-skid layer is provided on the outer side of the adjusting plate 6. The anti-skid layer can enhance the force between the adjusting plate 6 and the coil shaft 26 to prevent slipping. The left part of the adjusting plate 6 is rotatably connected to one end of the connecting block 7, and the other end of the connecting block 7 is rotatably connected to the small rotating wheel 5. At least one side wall of the connecting block 7 is fixedly connected to a fixing block 23, and the internal thread of the fixing block 23 is connected to a hexagonal bolt 24, and the hexagonal bolt 24 is in contact with the large rotating wheel 4. When the large rotating wheel 4 rotates, the hexagonal bolt 24 can resist the large rotating wheel 4, thereby fixing the connecting block 7, and then fixing the adjusting plate 6 to prevent the adjusting plate 6 from sliding when the large rotating wheel 4 rotates. The left part of the center of the small rotating wheel 5 is fixedly connected to a fixing rod 8, and the left part of the fixing rod 8 is slidably connected to the fixing rod 8. There is a first slider 811, the right part of the first slider 811 is square, and the left part is round. A first spring 813 is arranged between the first slider 811 and the fixed rod 8, and the two ends of the first spring 813 are respectively fixedly connected to the first slider 811 and the fixed rod 8. A first slide bar 812 is fixedly connected to the circular side wall of the first slider 811. A T-shaped plate 9 is slidably connected to the left part of the fixed tripod 3. An arc-shaped slide groove 911 is arranged on the side wall of the T-shaped plate 9. The first slide bar 812 slides in the arc-shaped slide groove 911. A rubber disc 25 is rotatably connected to the left part of the T-shaped plate 9. The rubber disc 25 can effectively absorb the vibration and impact brought by the cam 17, reduce the wear between the cam 17 and the T-shaped plate 9, and extend the service life of the equipment. A second Spring 10, two ends of the second spring 10 are fixedly connected to the fixed tripod 3 by T-shaped plates 9, a first rotating motor 11 is fixedly installed on the upper left part of the workbench 1, the first rotating motor 11 and the large rotating wheel 4 are both installed with pulleys, and a belt 111 is connected between the two pulleys, a second rotating motor 12 is fixedly installed on the inner wall of the right part of the workbench 1, the driving shaft of the second rotating motor 12 faces inward, the driving shaft of the second rotating motor 12 is fixedly connected to the first transmission rod 13, the left part of the first transmission rod 13 is fixedly connected to the driving bevel gear 14, the left part of the workbench 1 is rotatably connected to the second transmission rod 16, the bottom of the second transmission rod 16 is fixedly connected to the driven bevel gear 15, the driving bevel gear 14 and the driven bevel gear 15 are meshed with each other, and the top of the second transmission rod 16 is fixedly connected to the cam 17,The cam 17 contacts with the rubber disc 25, and the coil shaft 26 is put on the adjustment plate 6. Then the second rotating motor 12 is started. The driving shaft of the second rotating motor 12 drives the first transmission rod 13 to rotate, and then drives the driving bevel gear 14 to rotate. The driving bevel gear 14 drives the driven bevel gear 15 to rotate through meshing transmission, and then drives the second transmission rod 16 and the cam 17 to rotate. The rotation of the cam 17 pushes the T-shaped plate 9 to slide rightward in the fixed tripod 3. The T-shaped plate 9 squeezes the second spring 10. At the same time, the first sliding bar 812 slides in the arc-shaped sliding groove 911, and then drives the first slider 811 to rotate while sliding in the fixed rod 8. The rotation of the first slider 811 causes the fixed rod 8 to rotate, and the rotation of the fixed rod 8 drives the small rotating wheel 5 to rotate. The small rotating wheel 5 rotates Then the connection block 7 is driven to rotate, and the adjustment plate 6 slides in the slide groove of the large rotating wheel 4, and the adjustment plate 6 is tightened, reducing the gap between the adjustment plate 6 and the coil shaft 26, so that there is enough friction between the adjustment plate 6 and the coil shaft 26, ensuring the performance of the coil. Since the first slider 811 slides in the fixed rod 8, the first slider 811 squeezes the first spring 813. If the extrusion roller 22 does not contact the coil shaft 26 and the adjustment plate 6 is already tightened, the second rotating motor 12 continues to rotate, and the fixed rod 8 will no longer rotate, and the first slider 811 will no longer rotate. The first slider 811 only slides in the fixed rod 8 and squeezes the first spring 813 at the same time. Then the hexagonal bolt 24 is screwed on to fix the connection block 7, and then the adjustment plate 6 is fixed.

[0020] like Figure 1 and Figure 5As shown, it also includes a rotating block 18, a second slider 19, a second slide bar 20, a third spring 21 and an extrusion roller 22. The rotating block 18 is fixedly connected to the first transmission rod 13. The rotating block 18 is provided with a square incision, and the second slider 19 is slidably connected in the incision. The second slider 19 is fixedly connected to the second slide bar 20 at the lower part, and the lower part of the second slide bar 20 is slidably connected to the rotating block 18. A third spring 21 is provided between the second slider 19 and the rotating block 18. The third spring 21 is wound around the second slide bar 20. Both ends of the third spring 21 are fixedly connected to the rotating block 18 and the second slider 19, respectively. The left part of the second slider 19 is rotatably connected to the extrusion roller 22. When the second rotating motor 12 rotates, the driving shaft of the second rotating motor 12 drives the first transmission rod 13 to rotate. When the first transmission rod 13 rotates, it will also drive the rotating block 18 to rotate toward the adjustment plate 6, so that the extrusion roller 22 is close to the adjustment plate 6. When the extrusion roller 22 and the coil shaft 26 contact each other, the second rotating motor 12 is paused, and then the first rotating motor 11 is started. The first rotating motor 11 drives the belt 111 to rotate, and then drives the large rotating wheel 4 to rotate. The rotation of the large rotating wheel 4 drives the adjustment plate 6 and the small rotating wheel 5 to rotate, and then drives the coil shaft 26 to rotate, and then the copper foil 27 is wound on the coil shaft 26. The extrusion roller 22 is tightly attached to the outside of the coil shaft 26 under the action of the third spring 21, and then the extrusion roller 22 can flatten the copper foil 27 to keep the copper foil 27 flat and uniform, thereby ensuring product quality.
