Traditional brass strip cutting equipment has significant shortcomings in the copper strip feeding process: on the one hand, the feeding process relies on manual assistance, which is cumbersome and has low safety; on the other hand, existing equipment can only fix a single specification of copper strip winding cylinder, and when production needs change, equipment needs to be frequently replaced or the mechanical structure adjusted, which seriously restricts production flexibility and increases production costs.

[0003] To address the aforementioned issues, this invention proposes an innovative brass strip cutting device. By optimizing the collaborative design of the feeding mechanism and the cutting system, it achieves rapid adaptation and automated feeding of the copper strip winding cylinder, while simultaneously improving cutting accuracy and production efficiency.

[0021] Specifically, the feeding structure 1 includes a frame 3, a drive motor 31, a rotating cylinder 32, a moving part 33, and a tensioning part 34. The frame 3 is fixedly connected to the machine base. The drive motor 31 is a motor with a built-in reducer, which is fixedly connected to the frame 3, and its output end is fixedly connected to the rotating cylinder 32. The outer diameter of the rotating cylinder 32 is smaller than the inner diameter of the smallest specification copper strip winding tube, and a moving hole 35 is opened in its center. The moving hole 35 is a blind hole. The moving part 33 is inserted into the moving hole 35 and can move relative to it along the axial direction of the moving hole 35. The moving part 33 is a columnar structure, and the moving hole 35 is provided with... A spring-loaded spring 36 is provided, which presses against the bottom surface of the root groove of the moving hole 35 and the end of the moving member 33. The spring-loaded spring 36 is a spring. A contraction hole 37 is provided on the wall of the moving hole 35. Multiple contraction holes 37 are provided along the circumference of the moving hole 35. The tensioning member 34 is inserted into the contraction hole 37 and is connected to the moving member 33 through the connecting rod 38. As the moving member 33 moves, the tensioning member 34 can extend out of the contraction hole 37 and press against the inner wall of the copper strip winding cylinder. The outer diameter of the rotating cylinder 32 is not greater than the inner diameter of the smallest specification copper strip winding cylinder.

[0022] Specifically, the tensioning member 34 includes a fixed part 41, a cover part 42, and an elastic member 43. The connecting rod 38 is hinged to the fixed part 41, and the other end of the connecting rod 38 is hinged to the moving member 33. The cover part 42 is fitted onto the fixed part 41, and the two can move towards or away from each other along a single straight line. This single straight line is preferably the radial direction of the rotating cylinder 32. There is a movable gap between the fixed part 41 and the cover part 42. The elastic member 43 is located in the movable gap and presses against the cover part 42 and the fixed part 41 respectively. The elastic member 43 is preferably a compression spring.

[0023] Furthermore, the top of the fixing part 41 is provided with an elastic groove 51 on the side away from the frame 3. A stop table 52 is inserted into the elastic groove 51. The stop table 52 is covered with a rubber layer, and its top edge away from the frame 3 is provided with an arc chamfer 53. An elastic element 54 is provided in the elastic groove 51.

Through motor drive, the movable frame 6 can realize reciprocating motion in the direction pointing to the frame 3.

[0026] The specific implementation process of this utility model is as follows: In the initial state, the tensioning block body retracts into the contraction hole 37. First, the copper strip winding tube is sleeved on the rotating cylinder 32. After the end face of the copper strip winding tube is squeezed and the stop table 52 is contracted, it is sleeved onto the rotating cylinder 32. The moving device drives the moving frame 6 to move towards the frame 3. The push block 61 pushes the moving part 33 to move against the elastic force of the rebound part 36. The moving part 33 drives the tensioning part 34 to extend out of the contraction hole 37 through the transmission of the connecting rod 38 and presses against the inner wall of the copper strip winding tube. During this process, the fixing part 41 and the cover part 42 will move towards each other to adapt to different inner diameter sizes of the copper strip winding tube, thereby achieving the fixation of the copper strip winding tube. After the fixation is completed, the drive motor 31 is started, the copper strip is unwound, and under the drive of the conveying module of the cutting device, it enters the cutting module for successive cutting of the copper strip.
