[0026] like Figure 1-7 As shown, this utility model provides an automatic copper sheet winding and cutting machine, including a cutting component vertically arranged on a base, and an unwinding component and a winding component rotatably arranged on both sides of the cutting component. The unwinding component has an unwinding reel 8 detachably arranged inside and is equipped with a variety of unwinding reels 8 with different outer diameters. The winding component includes a winding reel 4 and a winding motor 1 that drives the winding reel 4 to rotate. The winding reel 4 is provided with a copper sheet clamping structure. The winding motor 1 is connected to a winding length counter. The unwinding reel 8 and the winding reel 4 are arranged opposite each other.

[0027] A pad is provided at the bottom of the base to ensure that the upper part of the base is in a horizontal state. When cutting copper sheets, first remove the unwinding reel 8 from the unwinding assembly, select an unwinding reel 8 that matches the inner diameter of the copper coil to be cut, place the two unwinding reels 8 at the two ends of the copper coil respectively, and then place the unwinding reel 8 together with the copper coil on the unwinding assembly, ensuring that the unwinding reel 8 and the winding reel 4 are in a straight line. Pull the end of the copper coil to pass through the cutting assembly, and use the clamping structure on the winding reel 4 to clamp the copper sheet at the moving end of the copper coil. Input the length of copper sheet to be cut at the controller input terminal of the winding assembly, and then the winding motor 1 in the winding assembly drives the winding reel 4 to rotate, winding the copper sheet onto the winding reel 4. After the counter reaches the set length, the winding motor 1 stops driving the winding reel 4 to rotate, and the operator cuts the copper sheet through the cutting assembly. Finally, release the clamping structure and remove the wound copper coil from the unwinding reel 8.

[0028] In a preferred embodiment of this utility model, the counter is an encoder connected to the winding motor 1, and the winding reel 4 is marked with a circumference scale. To control the thickness of each batch of copper foil and improve the winding quality, the circumference of the winding reel 4 is input to the controller input terminal of the winding assembly, and then the required length of copper foil to be cut is input. The controller in the winding assembly determines the required number of rotations of the winding reel 4, and then automatically controls the winding motor 1 to rotate the corresponding number of rotations, ensuring the cutting accuracy. The winding motor 1 can adjust the winding speed, has three speeds: fast, medium, and slow, and is equipped with an emergency stop button, which can be manually shut down in case of malfunction.

[0029] like Figure 6 As shown. The clamping structure includes a receiving groove at the edge of the winding disc 4 and an adjusting groove located at the edge of the winding disc 4. A clamping bolt is threaded into the adjusting groove, and the end of the clamping bolt is located inside the receiving groove. After inserting the end of the copper sheet to be wound into the adjusting groove, by inserting a wrench into the adjusting groove and rotating the clamping bolt, the end of the clamping bolt is pressed into the adjusting groove, thereby fixing the end of the copper sheet and ensuring the tightness of the copper sheet winding.

[0030] like Figure 1 and Figure 3As shown, to achieve the rotation of the winding reel 4 driven by the winding motor 1, the winding assembly includes a mounting frame 2 vertically fixed on the base. A mounting cylinder is horizontally rotatably connected to the mounting frame 2. The output shaft of the winding motor 1 is drively connected to the mounting cylinder. The movable end of the mounting cylinder is coaxially fixedly connected to the loading frame 3 via a flange structure. The winding reel 4 is fixedly connected to the loading frame 3. The output end of the winding motor 1 is coaxially fixedly connected to the mounting cylinder. The end of the mounting cylinder is provided with a flange and is fixedly connected to the loading frame 3 via the flange. By driving the mounting cylinder to rotate through the winding motor 1, the mounting cylinder drives the winding reel 4 mounted on the loading frame 3 to rotate, thereby realizing the automatic winding of the copper sheet.

[0031] like Figure 3 and Figure 7 As shown. The loading frame 3 includes a disc and a screw connected to the end of the disc. The disc is bolted to the flange at the movable end of the mounting cylinder. The screw is arranged at the edge of the disc and is set at equal angles around the axis of the disc. The winding disc 4 is bolted to the screw. The winding disc 4 located on the inner side directly abuts against the end wall of the disc and is locked with a nut. Then, another nut is screwed in, and another winding disc 4 is strung on the loading frame 3 and screwed in another nut. The other winding disc 4 is locked by clamping it with the two nuts. The position of the winding disc 4 can be adjusted by adjusting the position of the nuts.

[0032] like Figure 2 and Figure 5 As shown. The unwinding assembly includes a stand 6 fixedly mounted on the base. A support shaft 7 is horizontally rotatably connected to the top of the stand 6. A positioning head 10 is fitted onto the support shaft 7, and a threaded hole is provided on the support shaft 7. The positioning head 10 supports the shaft 7 by bolts. The unwinding reel 8 is detachably connected to the positioning head 10. To ensure the alignment of the unwinding reel 8 with the winding reel 4, a threaded hole is provided axially on the support shaft 7. By adjusting the position of the positioning head 10, the unwinding reel 8 is adjusted to be aligned with the winding reel 4.

[0033] like Figure 5 As shown. The positioning head 10 includes a sleeve, a fixed disc fixed on the sleeve, and a movable piece slidably fitted on the sleeve. Threaded holes are correspondingly provided between the positioning piece and the movable piece. A through hole corresponding to the threaded hole is provided on the unwinding reel 8. When replacing the unwinding reel 8, the bolt between the positioning piece and the movable piece is removed, allowing the positioning piece to slide out. Then, the unwinding reel 8 is replaced, and the movable piece is locked back onto the positioning piece using the bolt.

[0034] like Figure 2As shown. A rotating cylinder is horizontally rotatably arranged on the top of the support frame 6. One end of the support shaft 7 is located inside the rotating cylinder and is fixedly connected to the rotating cylinder by bolts. The winding assembly also includes a support rod 9 fixed on the base. The top end of the support rod 9 has an arc-shaped groove adapted to the support shaft 7, and the other end of the support rod 9 is connected to the support shaft 7. When installing the cut copper coil, first unscrew the bolt between the rotating cylinder and the support shaft 7, and pull the support shaft 7 out of the rotating cylinder. After removing the support shaft 7, depending on the position of the positioning head 10, if the spacing of the positioning head 10 cannot meet the installation requirements of the copper coil, remove the positioning head 10 from the support shaft 7. If no adjustment is required, determine whether the unwinding reel 8 is suitable. If it is necessary to replace the unwinding reel 8 with a different outer diameter, remove the movable piece and replace the unwinding reel 8. Then, tighten the movable piece with bolts, and finally install it on the support frame 6. The support rod 9 provides rotational support for the movable end of the support shaft 7.

[0035] like Figure 4 As shown. The cutting assembly includes a portal frame 51 vertically arranged on the base, with a cutting blade 53 rotatably arranged at one end of the top of the portal frame 51, and a guide platform 54 provided at the top of the portal frame. The guide platform 54 includes an arc-shaped surface at the top and an inclined surface and a horizontal surface connecting the two sides of the arc-shaped surface. The horizontal surface is located between the arc-shaped surface and the cutting blade 53.

[0036] The copper coil is unwound from the bottom and wound up from the bottom. The guide table 54 serves as a guiding structure, and its curved surface reduces friction. Additionally, a smooth chamfer is provided on the movable side of the horizontal surface. The horizontal surface ensures that the cutting shears 53 can smoothly cut the copper sheet. The end of the cutting shears 53 is rotatably connected to the portal frame 51 via a connecting shaft 52.

[0037] like Figure 4 As shown. The top of the portal frame 51 is provided with a limiting block 55 for supporting the movable end of the cutting scissors 53. When the cutting machine is not in use, the cutting scissors 53 is supported by the limiting block 55. The limiting block 55 is L-shaped, which can provide stable support for the cutting scissors 53 and achieve limiting.
