Description

Technical Field

[0001] This utility model relates to the field of copper processing technology, and specifically discloses a winding pressure head adjustment device. Background Technology

[0002] In the production of copper strip, the copper strip needs to be slit according to the width required by the customer before packaging. The slitting process of copper strip is as follows: the cleaned copper strip roll is first unwound by an uncoiler, then the waste edges are removed by an edge trimmer and it enters a loop buffer. After buffering, the roll enters a slitting shear, where it is slit in the width direction to the target width and number of strips. It then enters a loop buffer again. After buffering, the slit roll is cut off by a cross-cutting shear, and then each copper strip is separated by a separator on a winding machine before being wound up on the winding machine, thus realizing the slitting of the entire roll of copper strip.

[0003] During the separation process by the separator, as the outer diameter of the copper strip on the winding machine gradually increases, the angle at which the copper strip passes through the separator becomes smaller and smaller. At this point, manual operation is required to continuously raise the separator and adjust the angle between the copper strip and the separator to ensure the winding effect after separation. However, manual adjustment has significant drawbacks: First, manual operation cannot guarantee that the separator height is exactly consistent each time, resulting in deviations in the winding effect during each adjustment cycle; second, manual adjustment cannot ensure that the angle between the copper strip and the separator, and the gap between them, remains constant, leading to deviations in the winding effect within a single adjustment cycle. Therefore, a winding pressure head adjustment device is needed to solve this problem. Utility Model Content

[0004] This invention proposes a winding pressure head adjustment device, which realizes intelligent and precise adjustment of the separator height through photoelectric and PLC closed-loop control system. At the same time, the floating limit mechanism effectively separates the roll material while avoiding surface damage, significantly improving winding quality and production efficiency.

[0005] This utility model is implemented as follows: a winding pressure head adjustment device includes a winding machine, a winding separator is movably disposed on the outer wall of the winding machine, a hydraulic system is disposed on the outer wall of the winding machine, the output end of the hydraulic system is movably connected to the winding separator, a photoelectric detection device is disposed on the inner wall of the winding separator for detecting the outer diameter edge position of the roll material, and a limit mechanism is disposed on the inner wall of the winding separator for limiting the position of the slit roll material;

[0006] The limiting mechanism includes two swing arms, each with a through groove on its outer wall. A slider is slidably connected to the inner wall of each groove. A limiting roller is rotatably connected between the two sliders via a coupling. Multiple evenly distributed baffles are fixedly connected to the outer wall of the limiting roller. A spring is fixedly connected between the inner wall of the groove and the slider.

[0007] As a preferred embodiment of the winding pressure head adjustment device of this utility model, the photoelectric detection device includes a photoelectric emission detection device installed on the outer wall of one of the swing arms, and a photoelectric reflection device installed on the outer wall of the other swing arm.

[0010] As a preferred embodiment of the winding pressure head adjustment device of this utility model, the hydraulic system includes a hydraulic cylinder for driving the winding separator to rise and fall.

[0011] In a preferred embodiment of the winding pressure head adjustment device of this utility model, the photoelectric detection device and the limiting roller are not at the same height.

[0012] The beneficial effects of this utility model are:

[0013] 1. By electrically connecting the photoelectric detection device and the PLC control system, a closed-loop feedback control system is constructed, which can monitor the change of the outer diameter of the roll material in real time and automatically and accurately adjust the height of the separator, completely replacing the traditional manual operation and greatly improving the stability, consistency and production efficiency of the winding quality.

[0014] 2. The floating limiting mechanism composed of spring slider mechanism is adopted, which enables the limiting roller to always fit the surface of the roll material and adapt to its irregular fluctuations. While effectively preventing the roll material from being disordered or deviating, it avoids the scratches caused by rigid contact to the surface of the strip material, and has both excellent limiting effect and protection function.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0021] Please see Figure 1-3 The winding pressure head adjustment device includes a winding machine 1, a winding separator 2 movably mounted on the outer wall of the winding machine 1, a hydraulic system 3 mounted on the outer wall of the winding machine 1, the output end of the hydraulic system 3 being movably connected to the winding separator 2, a photoelectric detection device mounted on the inner wall of the winding separator 2 for detecting the outer diameter edge position of the roll material, and a limit mechanism mounted on the inner wall of the winding separator 2 for limiting the position of the slit roll material.

[0022] The limiting mechanism includes two swing arms 6. The outer walls of the two swing arms 6 are provided with sliding grooves 9. The inner walls of the two sliding grooves 9 are slidably connected to sliders 10. The two sliders 10 are rotatably connected to a limiting roller 7 via a coupling. The outer walls of the limiting roller 7 are fixedly connected to multiple evenly distributed baffles 8. The inner walls of the sliding grooves 9 and the sliders 10 are fixedly connected to springs 11.

[0023] In this embodiment: After the device is started, the slit copper strip is wound around the take-up separator 2 and abuts against the outer wall of the limiting roller 7. Multiple rolls are separated by baffles 8. As winding proceeds, the outer diameter of the roll gradually increases, and its edge position gradually approaches or blocks the light beam between the photoelectric emission detection device 4 and the photoelectric reflection device 5. The photoelectric detection device captures this position change in real time and transmits the signal to the external PLC control system. The PLC makes a judgment according to the preset program logic, and then sends a command to the hydraulic system 3 to drive the hydraulic cylinder to move, thereby precisely adjusting the overall height of the take-up separator 2 to maintain a constant optimal relative position with the increased outer diameter of the roll.

[0024] During this process, the limiting roller 7 remains firmly attached to the surface of the roll material under the tension of the spring 11, physically separating the multiple strips of roll material after slitting and preventing them from tangling or becoming disordered. The floating structure formed by the spring 11 and the slider 10 allows the limiting roller 7 to adapt to irregular fluctuations on the roll material surface, providing a stable and gentle limiting force and avoiding scratches on the strip surface. This invention, by combining a photoelectric detection device with a hydraulic follow-up system, achieves fully automatic and high-precision adjustment of the height of the winding separator 2, completely replacing the traditional manual operation that relies on worker experience, ensuring the stability and consistency of the winding process. At the same time, the floating limiting mechanism not only effectively prevents roll material deviation and mutual interference, but also avoids surface damage to the strip material that may be caused by rigid contact.

[0025] As a technical optimization of this utility model, the photoelectric detection device includes a photoelectric emission detection device 4 installed on the outer wall of one of the swing arms 6, and a photoelectric reflection device 5 installed on the outer wall of the other swing arm 6.

[0026] In this embodiment, the photoelectric detection device uses a high-sensitivity, long-distance, and anti-interference photoelectric through-beam sensor, which can accurately detect changes in the outer diameter of the roll material.

[0027] As a technical optimization of this utility model, the upper and lower end faces of the slide groove 9 are fixedly connected to the limit blocks 12, and the upper and lower end faces of the slider 10 are provided with limit grooves that are slidably connected to the limit blocks 12.

[0028] In this embodiment, the limiting block 12 and the limiting groove cooperate to limit the slider 10 and prevent the slider 10 from coming out.

[0029] As a technical optimization of this utility model, the photoelectric detection device is electrically connected to the external PLC control system.

[0030] In this embodiment, the PLC control system facilitates the processing of signals collected by the photoelectric detection device and controls the operation of the hydraulic system 3.

[0031] As a technical optimization of this utility model, the hydraulic system 3 includes a hydraulic cylinder for driving the winding separator 2 to rise and fall.

[0032] In this embodiment, the hydraulic cylinder facilitates the lifting and lowering of the winding separator 2.

[0033] As a technical optimization of this utility model, the photoelectric detection device and the limiting roller 7 are not at the same height.

[0034] In this embodiment, by setting the photoelectric detection device and the limiting roller 7 at different heights, interference of the limiting mechanism with the photoelectric detection device is prevented.

[0035] The working principle and usage process of this utility model are as follows: After the device is started, the slit copper strip is wound around the take-up separator 2 and abuts against the outer wall of the limiting roller 7. Multiple rolls are separated by baffles 8. As the winding proceeds, the outer diameter of the roll gradually increases, and its edge position gradually approaches or blocks the beam between the photoelectric emission detection device 4 and the photoelectric reflection device 5. The photoelectric detection device captures this position change in real time and transmits the signal to the external PLC control system. The PLC makes a judgment according to the preset program logic, and then sends a command to the hydraulic system 3 to drive the hydraulic cylinder to move, thereby accurately adjusting the overall height of the take-up separator 2 to maintain a constant optimal relative position with the increased outer diameter of the roll.

[0036] During this process, the limiting roller 7 remains in close contact with the surface of the roll material under the tension of the spring 11, physically separating the multiple strips of roll material after slitting to prevent them from tangling or becoming disordered. The floating structure composed of the spring 11 and the slider 10 allows the limiting roller 7 to adapt to irregular fluctuations on the surface of the roll material, providing a stable and gentle limiting force and avoiding scratches on the surface of the strip material.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
