Description

Technical Field

[0001] The invention relates to the technical field of copper strip slitting, in particular to a novel copper strip slitting machine. Background Art

[0002] The width of the copper strip is relatively large when it leaves the factory. In actual use, the originally wider copper strip needs to be cut into narrower copper strips for subsequent production operations. The existing copper strip slitting machines are all output by the unwinder, and then enter the disc shear for slitting after passing through the centering device, and then flow to the tension machine at the back to adjust the tension of the copper strip, and then flow to the winder at the back, and each group of copper strips is wound up by the winder with a separation frame; in actual use, since the copper strip needs to be cut into narrow copper strips of different widths, the disc needs to be adjusted. The shear's blade disc and blade shaft can be quickly adjusted, but the existing equipment, its centering device is directly connected to the disc shear, and the equipment is directly arranged behind the disc shear, which makes the replacement and adjustment of the disc shear blade disc time-consuming and laborious; and the existing copper strip slitting machine often has the phenomenon of unsynchronized copper strip speeds at the front and rear ends, which leads to poor feeding or discharging of the copper strip, causing the copper strip to stack or be stretched. For this reason, it is urgently needed to develop a corresponding copper strip slitting machine to make the copper strip move smoothly and reliably, and ensure that the disc shear blade disc can be replaced quickly and conveniently to ensure the production progress of the production line.

[0045] The pre-separation rack separates the adjacent copper strips of 80 strips to produce width intervals;

[0046] The unwinder 10, the clamping machine 20, the first looper 30, the centering guide mechanism 40, the disc shear 50, the edge material coiler 60, the second looper 70, the pre-separation frame 80, the tension machine 90, and the winder 100 are arranged in a straight line in sequence.

[0047] During specific implementation: the unwinder 10 is correspondingly provided with a loading trolley 110 , and the winder 100 is correspondingly provided with a unloading trolley 120 .

[0048] The first flip guide conveyor platform 32 and the second flip guide conveyor platform 72 are opened or closed by pivotally connected hydraulic cylinders, respectively. The feeding surfaces of the first flip guide conveyor platform 32 and the second flip guide conveyor platform 72 are feeding plates, and the surfaces of the feeding plates are paved with non-metallic plates to reduce the surface friction of the copper strip. The surfaces of the feeding plates are arranged with a number of inner pits, and ultrasonic or photoelectric switches are arranged in the inner pits, which are used to detect whether the speed of the copper strip passing through the surface matches the unwinder 10, the winder 100, and the disc shear 50, and at the same time, provide buffer adjustment in the case of mismatch;

[0049] A staircase 1 is provided at the position of one of the side panels of the first looper platform 30 and the second looper platform 70, which facilitates the operator to observe the conveying condition of the copper belt, so as to timely discover possible copper belt conveying speed mismatch defects.

[0050] During specific implementation, one side of the base 51 in the width direction protrudes outward from the guide roller 41 area of ​​the centering guide mechanism 40. When the cutting width needs to be switched, the upper mounting seat 52 moves along the bottom transverse track 53, so that the lower knife shaft mounting frame and the upper knife shaft mounting frame 54 are both arranged on the outer periphery in the width direction of the guide roller 41, and the operator can quickly replace the knife shaft and knife disc through the external space.

[0051] In a specific embodiment, the upper portion of the upper knife shaft mounting frame 54 is driven to rise and fall by a lifting servo mechanism 55 fixed to the top of the upper mounting seat, thereby adjusting the cutting depth of the cutter to match the trimming operation of copper strips of different thicknesses.

[0052] In a specific embodiment, the centering guide mechanism 40 includes a guide roller 41 and a plurality of centering guide wheels 42 located on both sides in the width direction. The centering guide wheel 42 is driven by a hand wheel 43 to adjust the position in the width direction, so that the centering guide wheel 42 is fine-tuned according to the width of the copper strip to ensure the centering guidance of the copper strip.

[0053] In a specific embodiment, a transition guide mechanism 130 is arranged between the circular shear 50 and the edge material curling machine 60. The transition guide mechanism 130 includes a flippable first guide roller frame 131. The first guide roller frame 131 is driven to open or close by a first hydraulic cylinder 132. When the first guide roller frame 131 is in the open state, the copper strip enters the edge material curling machine 60 along the end of the circular shear 50 through the roller of the first guide roller frame 131. The transition guide mechanism 130 is also correspondingly provided with a waste edge guide roller group 133. The waste edge guide roller group 133 guides the waste edges on both sides into the waste edge winding mechanism 62. When the first guide roller frame 131 is closed, the cutter disc can be replaced through the rear position of the circular shear 50.

[0054] During specific implementation, a first plate head shear 140 is further provided at the rear of the clamping and conveying machine 20 , and the first plate head shear 140 is used to cut off the head and tail parts of the copper strip to ensure reliable edge cutting and winding of the copper strip.

[0055] During specific implementation, the material receiving mechanism 21 at the front end of the clamping machine 20 is specifically a downward folding conveyor belt 23. The rear end of the frame of the downward folding conveyor belt 23 is connected to the lower frame of the clamping machine 20 through a first pivot shaft, and the middle lower end of the frame of the downward folding conveyor belt 23 is connected to the second hydraulic cylinder 24. The second hydraulic cylinder 24 drives the front end of the downward folding conveyor belt 23 to rotate to a suitable height position, thereby matching the copper strip conveyed from the uncoiler 10, so that the copper strip enters the guide roller mechanism 22 of the clamping machine 20 along the downward folding conveyor belt 23.

[0056] During specific implementation, a second plate head shear 150 is also provided behind the tension machine 90. The second plate head shear 150 performs timely shearing operations according to the conditions of the head and tail parts of the copper strip after passing through the tension machine to ensure the quality of the copper strip. A guide roller group 160 is also arranged at the rear end of the second plate head shear 150 to ensure that the copper strip can reliably enter the winder 100 for winding operations.

[0057] During specific implementation, a first guide roller group 2 is provided at the rear of the first plate head shear 140 corresponding to the working plane position of the first looper 30, a second guide roller group 3 is provided at the front of the centering guide mechanism 40 corresponding to the working plane position of the first looper 30, a third guide roller group 4 is provided at the edge material coiler 60 corresponding to the working plane position of the second looper 70, and a plurality of guide roller groups 5 are provided at the front end of the pre-separation frame 80 corresponding to the end of the second looper 70. The guide roller groups 5 guide the stripped copper strip into the pre-separation frame 70 at intervals in the width direction to complete the separation.

[0058] Its working principle is as follows: before the copper strip is slit, it is buffered or speed-regulated by the first looper, so that the conveying speed of the copper strip matches the speed of the disc shear; when the copper strip is not reeled after slit, it is buffered or speed-regulated by the second looper, so that the conveying speed of the copper strip after slit matches the reeling speed of the reel, which ensures that the copper strip moves smoothly and reliably; when the trimming width needs to be switched, the upper mounting seat moves along the bottom transverse track, so that the lower knife shaft mounting frame and the upper knife shaft mounting frame are both arranged on the outer periphery in the width direction of the guide roller, and the operator can quickly replace the knife shaft and knife disc through the external space; in addition, the waste edges on both sides obtained by slitting are also reeled up for secondary utilization.
