Description

Technical Field

[0001] The invention relates to the technical field of copper strip edge trimming, in particular to a copper strip continuous edge trimming 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 trimmed to form a copper strip of corresponding width that can adapt to the factory production. The existing copper strip trimming production line directly discards the trimming waste during the trimming operation, that is, the waste obtained by trimming falls directly from both sides of the trimming machine to the bottom, resulting in the waste edges cannot be reused. Since the cost of copper is relatively high, the inability to reuse the waste edges will increase production costs; and in the existing trimming production line, the trimming machine is directly fixed behind the incoming roller. When the trimming width of the trimming machine needs to be changed, due to the narrow space, the workers are time-consuming and laborious in replacing the knife shaft and knife disc of the trimming machine, which will delay the progress of the copper strip trimming production; for this reason, it is urgently necessary to develop a continuous trimming machine that can quickly replace the knife shaft and knife disc, and ensure that the copper waste edges can be recycled and reused. Summary of the invention

[0003] In view of the above problems, the present invention provides a continuous edge trimming machine for copper strips, which can quickly replace the knife shaft and the knife disc, and ensure that the copper waste edges can be recycled and reused.

[0041] In a specific embodiment, the uncoiler 10 is further provided with a front auxiliary support 80 and a loading trolley 90. The front auxiliary support 80 is located at the front of the uncoiler 10 and is used to support the main shaft head of the uncoiler 10 to prevent the main shaft of the uncoiler 10 from sagging due to force, thereby enhancing the carrying capacity of the uncoiler 10. The loading trolley 90 has lifting and horizontal movement functions and is used to lift the strip coil from the material preparation table and deliver the strip coil to the reel of the uncoiler 10.

[0048] A foldable first guide roller frame 120 is provided at the front end of the scrap edge machine 50. The first guide roller frame 120 is driven to open or close by a first hydraulic cylinder 121. When the first guide roller frame 120 is in the open state, the copper belt passes through the roller of the first guide roller frame 120 along the end of the edge trimmer 40 and enters the width direction guide roller group 51 of the scrap edge machine 50. When the first guide roller frame 120 is in the closed state, the operator can enter the area between the scrap edge machine 50 and the edge trimmer 40, thereby completing the maintenance work of the scrap edge machine 50 or the edge trimmer 40, and completing the replacement of the knife shaft and knife disc of the edge trimmer 40.

[0049] The bottom of the scrap edge machine 50 is also provided with a forward and backward moving mechanism 55. The scrap edge machine 50 can adjust its forward and backward position according to the position space when the first guide roller frame 120 is in the closed state, so as to facilitate the maintenance of the trimming machine 40, the scrap edge machine 50 and the tension machine 60.

[0050] A first plate head shear 130 is also provided behind the clamping and conveying machine 20. The first plate head shear 130 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.

[0051] A foldable second guide roller frame 140 is provided at the front end of the centering guide mechanism 30. The second guide roller frame 140 is driven to open or close by a second hydraulic cylinder 141. When the second guide roller frame 140 is open, the copper strip passes through the roller of the second guide roller frame 140 along the first plate head shear 130 and enters the centering guide mechanism 30 for centering operation. When the second guide roller frame 140 is closed, the operator can enter the area between the first plate head shear 130 and the centering guide mechanism 30 to complete the maintenance operation of the equipment in the corresponding area.

[0052] The material receiving mechanism 21 at the front end of the clamping and conveying machine 20 includes a first lower folding conveyor belt 150 and a second upper folding conveyor belt 160. The rear end of the frame of the first lower folding conveyor belt 150 is connected to the lower frame of the clamping and conveying machine 20 through a first pivot shaft. The middle lower end of the frame of the first lower folding conveyor belt 150 is connected to a third hydraulic cylinder 151. The third hydraulic cylinder 151 drives the front end of the first lower folding conveyor belt 150 to rotate to a suitable height position. The rear end of the frame of the second upper folding conveyor belt 160 is connected to the upper frame of the clamping and conveying machine 20 through a second pivot shaft. The middle upper part of the frame of the second upper folding conveyor belt 160 is connected to a fourth hydraulic cylinder 161. The fourth hydraulic cylinder 161 drives the front end of the second upper folding conveyor belt 160 to rotate to a suitable height position. The front ends of the first lower folding conveyor belt 150 and the second upper folding conveyor belt 160 match each other to guide the copper belt along the first lower folding conveyor belt 150 into the guide roller group of the clamping and conveying machine 20.

[0053] A second plate head shear 170 is also provided behind the tension machine 60. The second plate head shear 170 performs timely shearing operations according to the head and tail conditions of the copper strip after passing through the tension machine 60 to ensure the quality of the copper strip.

[0054] A guide roller group 180 is also arranged at the rear end of the second plate head shear 170 to ensure that the copper strip can reliably enter the winding machine for winding operation.

[0055] The working process is as follows: after the copper strip is unwound by the uncoiler, it enters the adapted feeding port formed by the first lower folding conveyor belt and the second upper folding conveyor belt. Then, the copper strip enters the guide pressure roller of the clamping machine along the surface of the first lower folding conveyor belt and is guided and conveyed. After that, it passes through the first plate head shear, and after the head and tail parts are cut off, the copper strip is sent to the centering guide mechanism through the second guide roller frame, and then enters the trimming machine for trimming. After trimming, the waste edge and the copper strip flow into the first guide roller frame together. Then, the waste edge is sent to the waste edge winding mechanism on the corresponding side through the waste edge guide roller group for winding. The copper strip is guided along the width direction of the roller group. Moving backward, the copper strip passes through the tension machine, the second plate head shear, the guide roller group in sequence, and then is reeled by the winder, and finally the copper strip coil is unloaded by the unloading trolley; the scrap edges cut off on both sides of the copper strip are reeled by the scrap edge reeling mechanism of the scrap edge machine, and the reeling speed of the scrap edge reeling mechanism is equal to the feeding speed of the copper strip, which ensures that the scrap edges can be reused according to demand; when it is necessary to switch the cutting width, the upper mounting seat moves along the bottom horizontal track, so that the lower knife shaft mounting frame and the upper knife shaft mounting frame are both arranged on the outer periphery of the guide roller in the width direction, and the operator can quickly replace the knife shaft and knife disc through the external space.
