[0026] Further, the limiting assembly 3 comprises a long plate 16, a sliding plate 17, a limiting plate 18 and a spring 19. The machine table 1 is provided with a pair of long plates 16 perpendicular to the transmission direction of the copper strip 43. The long plates 16 are provided with openings through which the copper strip 43 passes. A plurality of sliding plates 17 are slidingly connected between the long plates 16. The long plates 16 are provided with sliding grooves along the length direction. The two ends of the sliding plate 17 are slidingly connected with the sliding grooves, respectively. The limiting plate 18 is arranged below the sliding plate 17. The length direction of the limiting plate 18 is the same as the transmission direction of the copper strip 43. The limiting plate 18 is arranged on the two sides of the copper strip 43. A plurality of springs 19 are arranged between the top of the limiting plate 18 and the bottom of the sliding plate 17.

[0027] The limiting assembly 3 meets the limiting needs of the copper strip 43 with different widths and different discharge positions through a plurality of limiting plates 18 with adjustable positions, thereby improving the versatility. The fixing operation and unlocking operation of the limiting plate 18 are convenient, thereby reducing the workload of the staff adjusting the limiting plate 18. The staff adjusts the position of the limiting plate 18 according to the placement position of the copper strip 43 on the unwinding assembly 2, so that each copper strip 43 has two limiting plates 18 on the two sides when passing through the limiting assembly 3, thereby obtaining a better limiting effect.

The spring 19 is used to enhance the pressing force of the limiting plate 18, thereby improving the friction between the anti-skid layer 21 and the top of the machine table 1. When the limiting plate 18 needs to be moved, the staff only needs to hold the handle 20 and lift the limiting plate 18, so that the anti-skid layer 21 and the top of the machine table 1 are separated from each other. The sliding plate 17 and the limiting plate 18 can be freely moved. The operation is convenient. When the limiting plate 18 is moved to the predetermined position, the staff releases the handle 20. The anti-skid layer 21 is pressed on the top of the machine table 1 under the action of the gravity of the limiting plate 18 and the elastic force of the spring 19. The limiting plate 18 is prevented from deflecting by the cooperation of the guide rod 22 and the guide hole 23, thereby avoiding the improper arrangement of the limiting plate 18 on the two sides of the copper strip 43.
[0028] Further, the unwinding assembly 2 comprises a side plate 24, a rotating head 25, a rotating rod 26 and an unwinding disc 27. The machine table 1 is provided with a pair of front and rear symmetrical side plates 24. The rotating head 25 is rotatably connected to the side plate 24. The rotating rod 26 is detachably connected between the two rotating heads 25. The unwinding disc 27 is detachably connected to the rotating rod 26. The copper strip coil is mounted on the unwinding disc 27. The side plate 24 is provided with a locking assembly for controlling the rotating state of the rotating head 25. The locking assembly stops the rotating head 25 when the delivery assembly 4 stops and releases the rotating head 25 when the delivery assembly 4 starts.
[0029] The rotating rod 26 can be mounted on and detached from the rotating head 25. The unwinding disc 27 can be mounted on and detached from the rotating rod 26. The worker can conveniently mount a proper number of unwinding discs 27 on the rotating rod 26 according to the need. The locking assembly is used to control the discharging of the unwinding assembly 2, so as to avoid the copper strip 43 from being discharged too long due to the rotational inertia, causing the copper strip 43 to be slackened and affecting the processing of the copper strip 43.
[0030] Specifically, the inward end of the rotating head 25 is provided with a groove corresponding to the shape of the end of the rotating rod 26. The end of the rotating rod 26 is put into the groove. The groove and the end of the rotating rod 26 are provided with thread holes corresponding to each other. The rotating head 25 and the rotating rod 26 are detachably connected by screwing a connecting screw into the thread holes. The center of the unwinding disc 27 is provided with a mounting opening for the rotating rod 26 to pass through. The outer edge of the mounting opening is threadedly connected with a fixing screw. The detachable connection between the rotating rod 26 and the unwinding disc 27 is achieved by screwing the fixing screw against the outer wall of the rotating rod 26.
[0031] Further, the locking assembly comprises a telescopic rod A 28, a connecting table 29 and a stop piece 30. The side plate 24 is provided with the telescopic rod A 28 pointing to the rotating head 25. The movable rod of the telescopic rod A 28 is provided with the connecting table 29. The side of the connecting table 29 facing the rotating head 25 is provided with the stop piece 30. When the delivery assembly 4 stops, the stop piece 30 is abutted on the rotating head 25 under the action of the telescopic rod A 28. When the delivery assembly 4 starts, the stop piece 30 moves away from the rotating head 25 under the action of the telescopic rod A 28.
[0032] When the delivery assembly 4 stops transmitting the copper strip 43 to the cutting assembly 5, the telescopic rod A 28 presses the stop piece 30 on the rotating head 25, which timely stops the rotation of the unwinding disc 27 indirectly connected to the rotating head 25 through the rotating rod 26, thereby stopping the excessive discharging of the copper strip 43. When the delivery assembly 4 resumes transmitting the copper strip 43 to the cutting assembly 5, the telescopic rod A 28 removes the stop piece 30 from the rotating head 25. The rotating head 25, the rotating rod 26 and the unwinding disc 27 restore the rotating ability. The unwinding disc 27 rotates with the discharging of the copper strip 43.
[0033] Furthermore, the delivery component 4 includes a fixed frame A31, a drive roller 32, a driven roller 33, a motor 34, a lifting frame 35, a screw 36, and a throttle 37. The machine base 1 is provided with a U-shaped fixed frame A31, and the lifting frame 35 is slidably connected to the fixed frame A31. The two ends of the lifting frame 35 slide along the vertical part of the fixed frame A31. The top of the lifting frame 35 is rotatably connected to the screw 36 in the vertical direction. The top of the fixed frame A31 is provided with a threaded through hole that is threadedly connected to the screw 36. The top of the screw 36 is provided with a throttle 37. The driven roller 33 is rotatably connected to the lifting frame 35. The machine base 1 is rotatably connected to the drive roller 32 under the driven roller 33. The machine base 1 is provided with a motor 34 whose drive rod is coaxially connected to the rotating shaft of the drive roller 32. The driven roller 33 presses the copper strip 43 onto the drive roller 32. The drive roller 32 rotates under the action of the motor 34. The rotating drive roller 32 drives the copper strip 43 forward.
[0034] The operator adjusts the height of the driven roller 33 by rotating the handle 37. When the handle 37 is rotated, the screw 36 connected to the handle 37 is driven. The rotating screw 36 drives the lifting frame 35 to move up and down, thereby changing the height of the driven roller 33 on the lifting frame 35. This allows the driven roller 33 to be at the appropriate height to press the copper strip 43 onto the driving roller 32. The motor 34 provides the power to drive the driving roller 32 to rotate. The rotating driving roller 32 drives the copper strip 43 forward toward the cutting assembly 5 through friction. When the motor 34 stops, the copper strip 43 stops moving forward.
[0035] Furthermore, the cutting assembly 5 includes a fixed frame B38, a telescopic rod B39, a cutting blade 40, and a cutting groove 41. The machine base 1 is provided with a U-shaped fixed frame B38. The top of the fixed frame B38 is provided with a telescopic rod B39 in a vertical direction. The movable rod of the telescopic rod B39 passes downward through the fixed frame B38. The lower end of the movable rod of the telescopic rod B39 is provided with a cutting blade 40. The length direction of the cutting blade 40 is perpendicular to the transmission direction of the copper strip 43. The top of the machine base 1 is provided with a cutting groove 41 below the cutting blade 40. The shape of the groove opening of the cutting groove 41 corresponds to the shape of the cutting blade 40.
[0036] The cutting blade 40 is used to cut the portion of the copper strip 43 located below it. The lowering state of the cutting blade 40 is controlled by the telescopic rod B39, and the cutting groove 41 provides space for the cutting blade 40 to fall. When the portion of the copper strip 43 located behind the cutting groove 41 reaches the predetermined length, the operator manipulates the telescopic rod B39 to lower the cutting blade 40.
[0037] Furthermore, along the transmission direction of the copper strip 43, the machine base 1 is provided with a downwardly inclined feeding plate 42 after the cutting groove 41.
[0038] Workers can place a collection container on the feeding plate 42. The copper strip 43 cut by the cutting component 5 slides down the feeding plate 42 into the container, making it easy to discharge.
[0039] The working principle and use process of the utility model:
