Description

Technical Field

[0001] This utility model relates to the field of copper strip processing technology, specifically a copper strip correction device for a copper strip unwinding machine. Background Technology

[0002] Copper strip is a key raw material in industries such as electronics, power, and machinery, used for products like transformer windings, connectors, and heat sinks. Its production process typically includes rolling, annealing, and coating. Finished products are stored and transported in rolls. Uncoilers (also known as uncoilers) are crucial equipment for unwinding copper strip rolls and feeding them into subsequent processing equipment (such as slitting machines and stamping machines). The copper strip alignment device at the top of the uncoiler is mainly used to ensure alignment during copper strip winding, thereby avoiding winding skewing. However, during copper strip winding, it is inconvenient to quickly remove burrs generated after processing at the top of the copper strip.

[0003] To address the aforementioned deficiencies, existing technology (Chinese Patent No. CN220684213U, published on March 29, 2024) provides a copper strip correction device for a copper strip unwinding machine. An upper and lower grinding roller, installed between the feeding roller and the correction roller inside the unwinding machine, can be driven by a bottom electric push rod to clamp both ends of the copper strip and engage the upper and lower gears on one side of the upper and lower grinding rollers. Thus, when the upper grinding roller is driven to rotate by the drive motor, it can also drive the lower grinding roller to rotate synchronously, thereby removing burrs from the upper and lower end faces of the copper strip during transport. Simultaneously, a double-headed cylinder installed on one side of the inner support frame can also drive the grinding discs inside the connecting plates at both ends to move inward to both ends of the copper strip, thereby removing burrs from both sides of the copper strip. The removal of burrs from all four sides of the copper strip can collectively improve the uniform removal effect of burrs on the copper strip, ensuring that no burrs are left behind.

[0004] In the process of using the above solution, although corresponding grinding rollers and grinding discs are set to grind the burrs of the copper strip while correcting its deviation, the metal shavings after grinding will fall on the copper strip and the surface of the worktable, which is not convenient to clean in time, thus affecting the processing efficiency of subsequent processing steps. Summary of the Invention

[0005] The purpose of this utility model is to provide a copper strip correction device for a copper strip unwinding machine, so as to solve the problem mentioned in the background art that, although the existing copper strip correction devices for copper strip unwinding machines are equipped with corresponding grinding rollers and grinding discs to grind burrs on the copper strip while correcting its deviation, the metal shavings after grinding will fall on the copper strip and the surface of the worktable, which is not convenient to clean in time, thus affecting the processing efficiency of subsequent processing steps.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a copper strip correction device for a copper strip unwinding machine, comprising a worktable, mounting seats symmetrically installed on the top right side of the worktable, unwinding rollers rotatably connected between the mounting seats, a copper strip body being unwound on the unwinding rollers, the copper strip body passing through a fixed frame after being unwound, the fixed frame being installed in the middle of the top surface of the worktable, grinding rollers symmetrically rotatably connected to the inner side of the fixed frame, a copper strip body being conveyed between the grinding rollers, and a calibration plate symmetrically slidably connected to the top inner side of the fixed frame;

[0007] The left side of the fixed frame is symmetrically connected to the upper and lower sides with a dust suction pipe. The dust suction pipe is connected to the shaft of the grinding roller through a swing assembly. The dust suction pipe cleans the burrs on the copper strip body in time after grinding by swinging.

[0008] Furthermore, a reverse lead screw is rotatably connected through the top inner side of the fixing frame, and a calibration plate is symmetrically threaded onto the reverse lead screw. The top of the calibration plate slides in contact with the top inner side of the fixing frame.

[0009] The calibration plate is configured with a "U" shaped structure, and the inner walls of the left and right sides of the calibration plate are in contact with the outer side of the grinding roller. The calibration plate forms a spacing adjustment structure through a reverse lead screw.

[0010] Furthermore, a drive gear set is rotatably connected to the front side of the fixed frame. The shaft of the drive gear set is connected to the shaft of the grinding roller. The outer side of one of the gears in the drive gear set is connected to the output end of the motor. The motor is installed on the outside of the front side of the fixed frame.

[0011] Furthermore, the swing assembly includes a lever, which is fixedly mounted on the shaft of the vacuum tube, and a torsion spring is installed between the shaft of the vacuum tube and the fixed frame.

[0012] Furthermore, the lever on the suction pipe intermittently presses against the protrusion, which is installed at an equal angle on the outer side of the shaft of the grinding roller.

[0013] Furthermore, the suction pipe forms a reciprocating oscillating suction structure through a torsion spring, a lever, and a protrusion. The suction pipe is connected to a suction pump through a connecting pipe, and the suction pump is connected to a dust collection box through a connecting pipe. The suction pump and the dust collection box are respectively installed on the rear side and top of the fixed frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The copper strip correction device of this copper strip uncoiling machine can keep the copper strip on the center line during use by means of a calibration plate, so as to avoid deviation and affect subsequent processing. It can also grind and deburr the four sides of the copper strip at the same time, and collect the debris during grinding, so as to avoid the tedious operation of manually cleaning the debris left on the copper strip and the worktable surface, thus improving the processing efficiency.

[0016] Furthermore, after the unwinding roller on the mounting base releases the wound copper strip body, the copper strip body passes between the grinding rollers in the fixed frame. The top of the grinding rollers is symmetrically equipped with calibration plates to limit the two sides of the copper strip body and prevent deviation during the conveying process. The grinding rollers and calibration plates can remove burrs on all four sides of the copper strip body. At the same time, while removing burrs, the dust suction pipe can clean up the grinding debris in time, thereby avoiding contamination of the workbench 1.

[0017] Furthermore, after the motor starts, it drives the drive gear set to rotate, which in turn drives the grinding roller to rotate synchronously. This conveys the copper strip body while removing burrs from its surface. Rotating the reverse screw on the fixed frame causes the calibration plates to move relative to each other. This adjusts the distance between the calibration plates according to the width of the copper strip body, thereby correcting the deviation of the copper strip body and preventing it from skewing during conveying, which would affect the subsequent processing quality. At the same time, the calibration plates deburr the front and back sides of the copper strip body.

[0018] 3. Furthermore, when the grinding roller rotates, it drives the protrusion to rotate synchronously. After the protrusion rotates, it will intermittently press and contact the lever, thereby pushing the lever to rotate. After the lever rotates, it will drive the dust suction pipe to rotate synchronously, thereby reversing the torsion spring. When the protrusion and the lever are misaligned, the torsion spring will drive the dust suction pipe to rotate back to its original position, thereby causing the dust suction pipe to swing and suck up dust, effectively collecting the grinding debris in a timely manner and preventing it from scattering on the copper strip body and worktable 1. The dust pump provides suction power to the dust suction pipe, and the collected waste debris is concentrated in the dust collection box. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: Please refer to Figures 1-2 The present invention provides the following technical solution: a copper strip correction device for a copper strip unwinding machine, comprising a workbench 1, mounting bases 2 symmetrically mounted on the top right side of the workbench 1, unwinding rollers 3 rotatably connected between the mounting bases 2, a copper strip body 4 unwound on the unwinding rollers 3, the copper strip body 4 passing through a fixing frame 5 after unwinding, the fixing frame 5 being installed in the middle of the top surface of the workbench 1, grinding rollers 8 symmetrically rotatably connected to the inner side of the fixing frame 5, the copper strip body 4 being conveyed between the grinding rollers 8, a calibration plate 10 symmetrically slidably connected to the top inner side of the fixing frame 5, and a dust suction pipe 11 symmetrically rotatably connected to the upper and lower sides of the left side of the fixing frame 5, the dust suction pipe 11 being connected to the shaft of the grinding roller 8 through a swing assembly, the dust suction pipe 11 cleaning the burrs of the copper strip body 4 after grinding by swinging.

[0028] During use, after the unwinding roller 3 on the mounting base 2 releases the wound copper strip body 4, the copper strip body 4 passes between the grinding rollers 8 in the fixing frame 5. The top of the grinding rollers 8 is symmetrically equipped with calibration plates 10, which can limit the two sides of the copper strip body 4 to prevent deviation during the conveying process. The grinding rollers 8 and calibration plates 10 can remove the burrs on all four sides of the copper strip body 4. At the same time, while removing burrs, the dust suction pipe 11 can clean up the grinding debris in time, thereby avoiding contamination of the workbench 1. Example

[0029] Based on Embodiment 1, a structure for grinding and deburring all four sides of the copper strip body 4 is also disclosed. Please refer to [reference needed]. Figures 1-3As shown, its specific structure is as follows: A reverse lead screw 9 is rotatably connected through the top inner side of the fixed frame 5. A calibration plate 10 is symmetrically threaded onto the reverse lead screw 9. The top of the calibration plate 10 slides against the top inner side of the fixed frame 5. The calibration plate 10 is set as a "U" shaped structure. The inner walls of the left and right sides of the calibration plate 10 are in contact with the outer side of the grinding roller 8. The calibration plate 10 forms a spacing adjustment structure through the reverse lead screw 9. A drive gear set 7 is rotatably connected to the front side of the fixed frame 5. The shaft of the drive gear set 7 is connected to the shaft of the grinding roller 8. The outer side of one of the gears in the drive gear set 7 is connected to the output end of the motor 6. The motor 6 is installed on the outer front side of the fixed frame 5.

[0030] During use, after the motor 6 starts, it drives the drive gear set 7 to rotate. After the drive gear set 7 rotates, it drives the grinding roller 8 to rotate synchronously. This conveys the copper strip body 4 while removing burrs from its surface. After rotating the reverse screw 9 on the fixed frame 5, it drives the calibration plate 10 to move relative to each other. Then, the distance between the calibration plates 10 is adjusted according to the width of the copper strip body 4, thereby correcting the deviation of the copper strip body 4 and preventing it from being skewed during the conveying process, which would affect the subsequent processing quality. At the same time, the calibration plate 10 will deburr the front and back sides of the copper strip body 4. Example

[0031] Based on Embodiment 2, a structure for oscillating and vacuuming grinding debris is also disclosed. Please refer to [link / reference]. Figures 4-6 As shown, its specific structure is as follows: The swing assembly includes a lever 13, which is fixedly installed on the shaft of the suction pipe 11. A torsion spring 12 is installed between the shaft of the suction pipe 11 and the fixed frame 5. The lever 13 on the suction pipe 11 intermittently presses against the protrusion 14. The protrusion 14 is installed at equal angles on the outside of the shaft of the grinding roller 8. The suction pipe 11 forms a reciprocating swing suction structure through the torsion spring 12, the lever 13 and the protrusion 14. The suction pipe 11 is connected to the suction pump 15 through a connecting pipe. The suction pump 15 is connected to the dust collection box 16 through a connecting pipe. The suction pump 15 and the dust collection box 16 are respectively installed on the rear side and the top of the fixed frame 5.

[0032] During use, the grinding roller 8 rotates, which drives the protrusion 14 to rotate synchronously. After the protrusion 14 rotates, it intermittently presses against the lever 13, thereby pushing the lever 13 to rotate. After the lever 13 rotates, it drives the suction pipe 11 to rotate synchronously, which in turn reverses the torsion spring 12. When the protrusion 14 and the lever 13 are misaligned, the torsion spring 12 will drive the suction pipe 11 to rotate back to its original position, so that the suction pipe 11 swings to suck up dust, which can collect the grinding debris in a timely and effective manner, and prevent it from scattering on the copper strip body 4 and the worktable 1. The dust pump 15 provides suction to the suction pipe 11, and the collected waste is concentrated in the dust collection box 16.
