[0002] Copper strip coil sleeves are auxiliary tools used in the copper strip production process. They are mainly used to wind copper strip on a coiler to facilitate storage, transportation, and subsequent processing. Currently, after the copper strip coil undergoes annealing, it is wound onto the sleeve. The sleeve may deform, making it difficult to remove. However, there is currently no suitable mechanism to separate the copper strip coil and the sleeve, and manual operation is usually used, which is difficult, time-consuming, and disrupts normal production.

The copper strip winding device also cannot solve the technical problems described above. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a copper strip coil sleeve removal device that is simple in structure, easy to operate, and capable of separating the copper strip coil and the sleeve.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The copper strip coil sleeve removal device includes a support, on which a hydraulic cylinder is provided. The hydraulic cylinder includes a piston rod, and a connecting plate is fixedly connected to the end of the piston rod.

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this invention, and to facilitate its implementation.

[0022] like Figures 1 to 5As shown, the copper strip coil sleeve removal device includes a support 1, on which a hydraulic cylinder 2 is mounted. The hydraulic cylinder 2 includes a piston rod 3, with a connecting plate 4 fixedly connected to the end of the piston rod 3. A connecting rod 5 is fixedly connected to the connecting plate 4, and a pull rod 6 is detachably connected to the end of the connecting rod 5. The hydraulic cylinder 2 transmits power through liquid pressure, resulting in a large output force. The incompressibility of hydraulic oil allows it to maintain a relatively stable output force during operation. By applying force through the hydraulic cylinder 2, the pull rod 6 is ensured to apply force smoothly, guaranteeing that the sleeve 12 is successfully removed from the copper strip coil 11.

[0023] like Figure 1 and Figure 4 As shown, a bolt 8 is threaded onto the end of the connecting rod 5, and an adjusting groove 7 is provided on the pull rod 6. The bolt 8 passes through the adjusting groove 7 and presses the pull rod 6. The connecting rod 5 and the pull rod 6 are arranged perpendicularly. The adjusting groove 7 is strip-shaped and allows the pull rod 6 to move at the end of the connecting rod 5. During adjustment, simply loosen the bolt 8, move the pull rod 6 relative to the bolt 8 to the appropriate position, and then tighten it again. The adjustment operation is simple and convenient. In use, if the height of the hydraulic cylinder 2 and the axis height of the sleeve 12 do not correspond due to differences in the amount of copper strip coil 11 wound on the sleeve 12, the relative position of each pull rod 6 and the bolt 8 can be adjusted to ensure that each pull rod 6 can contact the edge of the sleeve 12.

[0024] like Figure 1 and Figure 5 As shown, the copper strip coil sleeve removal device also includes a base 9, on which the copper strip coil 11 is mounted, and a support 1 is located on one side of the base 9. The base 9 is fixed to the ground to stably support the copper strip coil 11. The base 9 can be manufactured by directly using a commonly used copper strip coil 11 storage base 9 and welding a baffle 10 to one side, thereby reducing costs. The side of the base 9 without the baffle 10 serves as the opening end for placing and removing the copper strip coil 11.

[0025] like Figure 1 and Figure 3 As shown, the connecting rods 5 are evenly distributed circumferentially on the connecting disc 4. There are four connecting rods 5, which are equally spaced. Each connecting rod 5 is equipped with a pull rod 6. During the sleeve removal process, multiple force application points are formed, the applied force is more uniform, and the overall force direction is aligned, reducing the generation of radial force. This facilitates the smooth removal of the sleeve 12 from the copper strip roll 11 in the axial direction and prevents the copper strip roll 11 from being carried out simultaneously, thus simplifying the removal process of the sleeve 12.

[0026] like Figure 5As shown, a baffle 10 is provided on one side of the base 9, and the top of the baffle 10 has an arc-shaped structure. The baffle 10 can be directly welded onto the existing base 9. The arc-shaped part at the top of the baffle 10 is used to prevent axial movement during the removal of the sleeve. The top of the baffle 10 is lower than the bottom of the sleeve 12. During the removal of the copper strip coil 11 from the sleeve, the copper strip coil 11 is blocked by the baffle 10. The baffle 10 will apply a supporting force to the copper strip coil 11. This supporting force is opposite to the force applied by the pull rod 6 to the sleeve 12. Therefore, the copper strip coil 11 after the sleeve is removed will stay on the base 9 and will not be damaged secondaryly. It also maintains the overall winding state of the copper strip coil 11 basically unchanged, which is convenient for collection, reassembly and storage.

[0027] like Figure 5 As shown, the top of the base 9 has an arc-shaped structure. The copper strip coil 11 and the base 9 make arc-shaped contact, which prevents stress concentration and reduces damage to the copper strip coil 11. The arc-shaped contact also prevents the copper strip coil 11 from rolling, improving the safety of production operations.

[0028] like Figure 1 As shown, the connecting rod 5 extends from the inner cavity of the sleeve 12, the pull rod 6 abuts against the end of the sleeve 12 away from the hydraulic cylinder 2, and the baffle 10 abuts against the side of the copper strip roll 11 closest to the hydraulic cylinder 2. This structure describes the removal process of the sleeve 12. The direction of the force applied by the pull rod 6 to the sleeve 12 is opposite to the direction of the force applied by the baffle 10 to the copper strip roll 11. When the pull rod 6 moves from one side of the copper strip roll 11 to the other side, the sleeve 12 can be completely removed from the copper strip roll 11.

[0029] The working process is as follows: The copper strip roll 11 is placed on the base 9, and the bolts 8 are loosened to bring the four tie rods 6 closer together to reduce the unfolded volume so that they can be inserted into the cavity of the sleeve 12. The hydraulic cylinder 2 is activated and the connecting rod 5 and the tie rod 6 are extended from the cavity of the sleeve through the piston rod 3. The operator adjusts the relative position of the tie rod 6 and the bolt 8 to ensure that the end of each tie rod 6 can contact the end of the sleeve 12. The hydraulic cylinder 2 is activated and retracts to pull the connecting rod 5. Each tie rod 6 contacts the sleeve 12 and applies force to it. At the same time, the copper strip roll 11 is abutted by the baffle 10. The sleeve 12 is pulled by the tie rod 6 and thus removed from the copper strip roll 11. At the same time, the copper strip roll 11 and the base 9 are relatively stationary, avoiding the defect of the copper strip roll 11 moving with the sleeve 12 and causing further damage.

[0030] In actual use, the connecting rod 5 and piston rod 3 of the corresponding length can be replaced according to the length of the sleeve 12. The installation distance between the base 9 and the support 1 can also be increased so that the sleeve 12 can be placed between the base 9 and the support 1 after it is taken out. Furthermore, an anti-roll cage for the sleeve 12 can be set between the base 9 and the support 1 to avoid the safety risk caused by the sleeve rolling after it is taken out and is no longer under force.

[0031] The copper strip roll sleeve removal device uses a hydraulic cylinder 2 to drive a pull rod 6 to apply force to the sleeve 12, and under the blocking action of the base 9, it separates the copper strip roll 11 from the sleeve 12, replacing the traditional manual removal method and solving the problem of the sleeve 12 being deformed and difficult to remove. The device has a simple structure, is easy to operate, and can ensure the normal operation of production.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
