Description

Technical Field

[0001] The invention relates to the technical field of paper-wrapped copper stranded wire production, in particular to a paper-wrapped copper stranded wire end paper-wrapped cutting device. Background Art

[0002] Copper stranded wire is a copper wire made of multiple copper wires twisted together. It is widely used in power equipment. With the rapid development of transformer production, the lead wire process of the transformer body has developed synchronously. The workload of the paper-wrapped copper stranded wire end paper removal process is relatively prominent, and the removal process is labor-intensive. Especially if the paper-wrapped copper stranded wire is tightly wound and the inner layer is coated with glue, the paper-wrapped copper stranded wire end paper removal and stripping process is particularly difficult.

[0003] In the prior art, the removal of the wrapping paper at the end of the paper-wrapped copper stranded wire is mostly done manually. Manual removal first requires determining the excess wrapping paper at the end of the paper-wrapped copper stranded wire, and then using a cutting tool to remove the excess part of the paper-wrapped copper stranded wire. The manual incision is not only uneven, but also cannot guarantee that the excess wrapping paper is completely removed around the paper-wrapped copper stranded wire, thereby reducing the overall quality of the paper-wrapped copper stranded wire. In addition, the manual cutting process has high labor intensity and low work efficiency. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Replace the inner support tube according to the inner wall radius of the excess wrapping paper at the end of the paper-wrapped copper stranded wire. Twist the inner support tube so that the inner support tube is threadedly connected to the circumferential surface of the cylindrical mounting seat. After feeding the paper-wrapped copper stranded wire into the sleeve positioning plate, the excess wrapping paper at the end of the paper-wrapped copper stranded wire is sleeved on the circumferential surface of the inner support tube, and the paper-wrapped copper stranded wire is pushed inward until it cannot be pushed. The reason why the paper-wrapped copper stranded wire cannot be pushed is that the side end of the inner support tube is against the internal copper stranded wire, and the accommodation gap of the inner support tube is set to be able to abut the end of the internal copper stranded wire, and the cutting blade is kept in the accommodation gap. Horizontally and vertically, the position where the cutting blade cuts downward is exactly the position of the excess paper wrapping the paper wrapped copper stranded wire. Then, hold the handle to drive the rotating rod to rotate, and the rotation of the rotating rod drives the bidirectional screw to rotate. The rotation of the bidirectional screw drives the two first threaded plates to move in a direction close to each other, thereby driving the four arc-shaped clamping plates on both sides to clamp and limit the paper wrapped copper stranded wire, ensuring that the paper wrapped copper stranded wire can remain stable during the cutting process. The anti-slip pad in the arc-shaped clamping plate is used to increase the friction between the arc-shaped clamping plate and the paper wrapped copper stranded wire, making it more stable.

[0016] 2. Start the driving motor to drive the first rotating shaft to rotate, the rotation of the first rotating shaft drives the driving gear to rotate, the rotation of the driving gear drives the first gear ring to rotate, the rotation of the first gear ring drives the extension plate fixedly connected to the first gear ring to perform circular motion, the circular motion of the extension plate drives the cutting blade to cut, and while the extension plate performs circular motion, it drives the first driven gear connected to the third groove to mesh with the second gear ring, the first driven gear meshes with the second gear ring when performing circular motion, the second gear ring drives the first driven gear to rotate, the rotation of the first driven gear drives the second driven gear to rotate, the rotation of the second driven gear drives the driving screw to rotate, the rotation of the driving screw drives the second threaded plate to move, the second threaded plate moves and pushes the second trapezoidal extrusion block to move through two connecting rods, the second trapezoidal extrusion block laterally extrudes the first trapezoidal extrusion block along the inclined surface of the first trapezoidal extrusion block, the first trapezoidal extrusion block The trapezoidal extrusion block is squeezed to move downward, and the downward movement of the first trapezoidal extrusion block drives the adjusting block to move downward. The downward movement of the adjusting block drives the cutting blade to move downward. The first driven gear continuously follows the first gear ring to perform circular motion during the rotation of the first gear ring, thereby continuously driving the second driven gear and the driving screw to rotate. The rotation of the driving screw will push the second trapezoidal extrusion block to squeeze the first trapezoidal extrusion block little by little, so that the first trapezoidal extrusion block gradually moves downward. The downward movement of the first trapezoidal extrusion block will slowly drive the cutting blade to move downward, so that it can gradually approach the center of the paper-wrapped copper stranded wire during the rotation and cutting process, so that it can complete the cutting of the excess wrapped wire of the paper-wrapped copper stranded wire. At the same time, because the inner support tube is against the end of the copper stranded wire core to open a certain accommodating gap, the cutting blade can reach the inner wall of the excess wrapped paper of the paper-wrapped copper stranded wire in time, and there is no need to worry about the rigid release from the inner support tube, which effectively protects the service life of the cutting blade.

[0017] In the present invention, the device automates the entire process of cutting the excess wrapping paper of the paper-wrapped copper stranded wire through the mutual cooperation between various groups of mechanisms, thereby saving the time of manually searching for the excess wrapping paper at the end of the paper-wrapped copper stranded wire. At the same time, the cutting mechanism is used to drive the cutting blade to perform circular cutting, so that the cut surface can be kept smooth, which effectively improves the overall quality of the paper-wrapped copper stranded wire, while reducing the labor intensity of the staff and increasing work efficiency.

The reason why the paper-wrapped copper stranded wire cannot be pushed is that the side end of the inner support tube 12 abuts against the internal copper stranded wire, and the accommodation gap of the inner support tube 12 is set to abut against the end of the internal copper stranded wire, and the cutting blade 28 is in contact with the accommodation gap. The gap is kept horizontal and vertical, and the position where the cutting blade 28 cuts downward is just the position of the excess paper of the paper-wrapped copper stranded wire.

The first trapezoidal extrusion block 30 is squeezed and moves downward, and the downward movement of the first trapezoidal extrusion block 30 drives the adjustment block 25 to move downward, and the downward movement of the adjustment block 25 drives the cutting blade 28 to move downward. The first driven gear 21 continuously follows the first gear ring 13 to perform circular motion during the rotation of the first gear ring 13, thereby continuously driving the second driven gear 22 and the driving screw 23 to rotate. The rotation of the driving screw 23 will push the second trapezoidal extrusion block 31 to squeeze the first trapezoidal extrusion block 30 little by little, so that The first trapezoidal extrusion block 30 gradually moves downward, and the downward movement of the first trapezoidal extrusion block 30 will slowly drive the cutting blade 28 to move downward, so that it can gradually approach the center of the paper-wrapped copper stranded wire during the rotational cutting process, so that it can complete the cutting of the excess wrapped wire of the paper-wrapped copper stranded wire. At the same time, due to the accommodation gap provided at the end of the inner support tube 12 against the copper stranded wire core, the cutting blade 28 can reach the inner wall of the excess wrapped paper of the paper-wrapped copper stranded wire in time, and there is no need to worry about the rigid release of the inner support tube 12, which effectively protects the service life of the cutting blade 28. ;
