[0002] In modern industrial production, metal processing technology continues to develop towards refinement and high efficiency and energy conservation, especially for the processing of highly conductive conductor materials such as copper. Its surface quality and dimensional accuracy directly affect the performance and cost of the final product. Traditional copper strip processing technology often faces problems such as low efficiency, high energy consumption, difficult precision control, and unstable surface quality during the processing process. In particular, the thickness consistency is difficult to accurately control.

[0003] Chinese patent publication number CN115007648A discloses a single-stand reversible rolling device for ultra-thin wide copper strips.

This makes it easy for the subsequent cutting roller to be unable to effectively cut the workpiece when the thickness of the workpiece is different, and the waste workpiece after cutting is not convenient to collect and clean.

The output end of the first rotary drive 3 is provided with a first rotating roller 33 and a second rotating roller 34 for supporting the rotation of the conveyor belt 2. The outer sleeve of the first rotating roller 33 is provided with a first transmission belt 35 connected to the second rotating roller 34, and the outer sleeve of the second rotating roller 34 is provided with a second transmission belt 36 connected to the first rotating rod 73. The second rotating rod 51 is provided on the second cutting roller 72 and fixed coaxially with the second cutting roller 72, and the other end of the second rotating rod 51 is connected to the hinged rod 62 by a bearing. The multi-stage extruded copper strip rolling device usually includes multiple rolling units, each unit consists of a pair or more pairs of rollers, and the gap and pressure of these rollers can be precisely controlled by a special adjustment system. During the rolling process, the copper strip passes through multiple rolling units, each of which extrude and rolls it to a certain degree, thereby gradually reducing its thickness and improving its surface quality. Multi-stage extrusion is achieved through multiple rolling units.

[0028] By starting the first rotary driver 3, the first rotary roller 33 can be rotated, and when the first rotary roller 33 rotates, the rotational force can be transmitted to the second rotary roller 34 through the first transmission belt 35, and the conveyor belt 2 can be driven, so that the workpiece on the conveyor belt 2 can be transported to between the first cutting roller 71 and the second cutting roller 72. When the displacement sensor 32 detects that the workpiece is located on the conveyor belt 2, the second rotary driver 53 is started by the controller 31, and then the second rotary driver 53 is started to drive the sliding block 61 and the limiting plate 65 to move horizontally in a straight line. When the limiting plate 65 and the sliding block 61 move, the hinged rod 62 rotatably arranged on the limiting plate 65 can drive the second connecting rod 64 to slide vertically along the limiting groove 63, and then the squeezing roller 4 and the second cutting roller 72 are synchronously raised or lowered to achieve synchronous adjustment, so that the extrusion and cutting of the copper strip are carried out synchronously, and copper strips of different thicknesses can be extruded and cut, thereby improving the applicability of the device.

[0029] See also Figure 3 and Figure 5 As shown, the adjustment mechanism 5 also includes a second rotation driver 53 and a threaded rod 54; the second rotation driver 53 is arranged on the body 1; the input end of the threaded rod 54 is connected to the output end of the second rotation driver 53 through a coupling, and two pairs of mounting plates 55 are provided on the body 1; a pair of limiting rods 56 are installed between the two mounting plates 55, and the limiting rods 56 are used to limit the sliding block 61 to make stable horizontal linear sliding.

[0030] When the squeeze roller 4 needs to be lowered vertically, the displacement sensor 32 transmits a signal to the controller 31, which in turn activates the second rotary actuator 53. When the second rotary actuator 53 is activated, it drives the threaded rod 54 in synchronous rotation. A sliding block 61 is mounted on the threaded rod 54. As the threaded rod 54 rotates, the sliding block 61 slides vertically along the threaded rod 54, thereby adjusting the squeeze roller 4 vertically.

[0031] See also Figure 3 and Figure 5 As shown, the drive connection mechanism 6 includes a sliding block 61 and a hinge rod 62; the sliding block 61 is slidably set on the body 1 and is threadedly connected to the threaded rod 54; the hinge rod 62 is rotatably set on the sliding block 61, and one end of the sliding block 61 extending out of the outside of the body 1 is installed with a limiting plate 65 rotatably installed between the hinge rod 62, and a circular hole for the limiting rod 56 to pass through is provided on the sliding block 61, and the sliding block 61 is clearance-matched with the limiting rod 56, and a travel groove 66 for the limiting plate 65 to slide horizontally and linearly is provided on the body 1, and the other end of the hinge rod 62 is located in the limiting groove 63 and slides.

[0032] When the threaded rod 54 rotates, it drives the externally threaded sliding block 61 to slide horizontally. This sliding movement of the sliding block 61 causes the limiting plate 65 to slide smoothly horizontally along the travel groove 66 and the limiting rod 56. The limiting plate 65 then drives the hinged rod 62, which extends outside the travel groove 66, to adjust the vertical position of the squeeze roller 4 and the second cutting roller 72 through the connection between the hinged rod 62 and the squeeze roller 4 and the second cutting roller 72.

[0033] See also Figure 5 and Figure 6 As shown, the drive connection mechanism 6 also includes a limiting groove 63 and a second connecting rod 64; the limiting groove 63 is opened on the body 1 and cooperates with the groove of the hinge rod 62; the second connecting rod 64 is rotatably set on the hinge rod 62, and the limiting groove 63 has a pair, and the limiting groove 63 and the third rotating rod 52 are matched with each other. The two ends of the third rotating rod 52 extend out of the outside of the body 1 and are rotatably connected to the second connecting rod 64. A connecting plate is provided on the body 1, and a guide positioning rod 67 is provided on the connecting plate to limit the vertical sliding of the second connecting rod 64.

[0034] When the hinged rod 62 drives the second rotating rod 51 to move downward, the second rotating rod 51 slides in the limiting groove 63, which makes the sliding block 61 and the limiting plate 65 slide in the horizontal direction. At the same time, the hinged rod 62 is driven to drive the second rotating rod 51 to slide and adjust in the vertical direction in the limiting groove 63 through the guidance of the limiting groove 63, thereby ensuring the stability of the sliding movement. The hinged rod 62 is set in the middle of the second connecting rod 64, and the sliding of the second connecting rod 64 in the vertical direction is limited by the guide positioning rod 67, which makes the hinged rod 62 drive the second connecting rod 64 to move upward more smoothly. Stable and synchronous movement: When the hinged rod 62 tilts to the left or right, the second connecting rod 64, pivotally connected to the hinged rod 62, drives the third rotating rod 52, coaxially fixed to the squeeze roller 4, to rise or fall synchronously along the limiting groove 63. This allows the squeeze roller 4 and the second cutting roller 72 to move closer to or further away from the conveyor belt 2 and above the first cutting roller 71. The friction between the squeeze roller 4 and the second cutting roller 72 and the workpiece on the conveyor belt 2 causes them to rotate in contact with the workpiece, driven by the conveyor belt 2, thereby squeezing and cutting the workpiece. This design allows the sliding block 61 and the limiting plate 65 to move synchronously upward or downward via the hinged rod 62 and the second connecting rod 64, eliminating the need to adjust their spacing from the conveyor belt 2. This ensures that the squeeze roller 4 and the second cutting roller 72 are always at the same level, facilitating the squeezing and cutting of workpieces of varying thicknesses and simplifying the operation.

[0035] See also Figure 6 and Figure 7As shown, the cutting mechanism 7 includes a first cutting roller 71 and a second cutting roller 72; the first cutting roller 71 is rotatably set on the body 1 and close to one side of the conveyor belt 2; the second cutting roller 72 is rotatably set on the hinge rod 62, and a first rotating rod 73 is provided on the body 1 and is coaxially fixed with the first cutting roller 71, and a plurality of cutting grooves 74 are provided on the first cutting roller 71, and a cutting blade 75 in contact with the cutting groove 74 is provided on the second cutting roller 72.

[0036] When the distance between the second cutting roller 72 and the first cutting roller 71 needs to be adjusted, the adjustment mechanism 5 causes the articulated rod 62 to tilt at a certain angle. This tilting action drives the second rotating rod 51, to which one side of the articulated rod 62 is pivotally connected, to descend vertically. Because the second rotating rod 51 is coaxially fixed with the second cutting roller 72, the downward movement of the second rotating rod 51 is directly converted into the vertical sliding of the second cutting roller 72, causing it to move closer to the first cutting roller 71. During the movement of the sliding block 61 and the limiting plate 65, the linkage between the articulated rod 62 and the second rotating rod 51 allows precise sliding adjustment of the second cutting roller 72 relative to the first cutting roller 71, thereby adapting to the cutting requirements of workpieces of varying thicknesses and ensuring cutting accuracy and efficiency.

[0037] See also Figure 6 and Figure 7 As shown, the collecting mechanism 8 includes a scraper 81 and a guide block 82; the scraper 81 is arranged in the body 1 and is located below the second cutting roller 72; the guide block 82 is arranged on the body 1 and close to one side of the scraper 81, and the body 1 is provided with a mounting plate 55 for mounting the scraper 81; the guide block 82 is an arc shape that better fits the rolling and falling of waste, and a plurality of guide grooves 83 for waste to enter are provided on the guide block 82, and a pull-out box 84 extending from the outside of the guide block 82 and used to collect waste is slidably provided on the guide block 82.

[0038] After the workpieces are squeezed by the squeezing roller 4 on the conveyor belt 2, they enter between the second cutting roller 72 and the first cutting roller 71. The second cutting roller 72 cuts the workpiece located above the first cutting roller 71. The waste generated during the cutting process accumulates in the cutting groove 74. As the first cutting roller 71 rotates driven by the second transmission belt 36, the scraper 81 continuously contacts the cutting groove 74, scraping away the waste. The scraped waste falls onto the guide block 82 and slides along the guide trough 83 into the drawer box 84. When the waste in the drawer box 84 accumulates to a certain level, the user simply pulls the drawer box 84 to dump the waste, reducing the fatigue of manual cleaning later.

[0039] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
