Description

Technical Field

[0001] The utility model belongs to the technical field of calendered copper foil processing, and particularly relates to a sleeve conversion disc for calendered copper foil. Background Technique

[0002] At present, the Chinese utility model with the publication number of CN218503017U discloses a sleeve conversion disc for calendered copper foil, which relates to the technical field of calendered copper foil processing equipment and includes a disc body. One side disc surface of the disc body is detachably connected to the end surface of a large-diameter sleeve, and an insertion part for inserting a clamping top cone of a small-diameter sleeve is arranged on the other side disc surface. The inner surface of the insertion part has an annular conical section coaxially arranged with the disc body, and the annular conical section is used for abutting against the clamping top cone of the small-diameter sleeve. The disc body in this utility model enables the large-diameter sleeve to also be used on the processing equipment of the small-diameter sleeve, without the need to use a rewinding device to transfer the calendered copper foil from the large-diameter sleeve to the small-diameter sleeve. This not only avoids the risk of defects in the calendered copper foil caused during the rewinding process, but also the conversion disc can be sequentially installed at both ends of the large-diameter sleeve, which is more convenient to install compared to the rewinding process and can improve the processing efficiency.

[0003] Although the conversion disc of the above patent can convert the calendered copper foil sleeve, it is only limited to the calendered copper foil sleeve of a single barrel diameter model and cannot fix calendered copper foil sleeves of multiple different models according to actual production needs. Therefore, its practicability is low. At the same time, the conversion disc needs to be installed at both ends of the large-diameter sleeve at one time to convert and fix the calendered copper foil sleeve, which is relatively troublesome to operate in practice. Moreover, it is not convenient to effectively limit the calendered copper foil sleeve, resulting in the sleeve being prone to offset during the stretching process of the calendered copper foil. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a sleeve conversion disc for calendered copper foil, which has the advantages of being convenient for converting and fixing calendered copper foil sleeves of multiple different barrel diameter models, and at the same time can limit the sleeve during the stretching process of the calendered copper foil.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A sleeve conversion disc for calendered copper foil includes a conversion disc. A double-sided bevel gear is slidably connected inside the conversion disc. One side at the bottom of the double-sided bevel gear meshes with a first bevel gear rotatably connected to the conversion disc. Four single-threaded screws are symmetrically and rotatably connected inside the conversion disc. One end of each of the four single-threaded screws, which is far away from each other, is fixedly connected to a second bevel gear meshing with the top of the double-sided bevel gear. A first thread sleeve is threadedly sleeved on the surface of the single-threaded screw. An inner support rod is fixedly connected to the top of the first thread sleeve. A limit chute for slidably connecting with a limit disc is opened at the top of the conversion disc.

[0006] With the above technical solution, by sleeving the calendered copper foil sleeve on the surface of the inner support rod, and then controlling the inner support rods to open outwards, so as to contact the inner ring of the calendered copper foil sleeve, various types of calendered copper foil sleeves can be fixed on a single type of uncoiler. The practicability of the conversion disk is improved, and at the same time, it is also convenient to install the calendered copper foil sleeve, improving the processing efficiency; the two limiting disks can be close to each other to clamp both sides of the calendered copper foil sleeve, so that the calendered copper foil sleeve cannot slide left and right on the surface of the inner support rod. Furthermore, the position deviation of the copper foil after being stretched from the sleeve is prevented, which is convenient for subsequent processing of the calendered copper foil and improves the practicability.

[0007] The present utility model is further configured as: a double-threaded screw rod is rotatably connected inside the inner support rod, both ends of the surface of the double-threaded screw rod are threadedly sleeved with second threaded sleeves, limiting disks are slidably sleeved at both ends of the surface of the inner support rod close to the two second threaded sleeves, a guiding chute is opened on the surface of the inner support rod, and connecting blocks that are slidably connected with the guiding chute are fixedly connected between the second threaded sleeves and the limiting disks.

[0008] With the above technical solution, the position deviation of the copper foil after being stretched from the sleeve is prevented, which is convenient for subsequent processing of the calendered copper foil and improves the practicability.

[0009] The present utility model is further configured as: a ball that is slidably connected with a double-sided bevel gear is rotatably connected inside the conversion disk.

[0010] With the above technical solution, the friction force of the double-sided bevel gear sliding inside the conversion disk is reduced, and the sliding stability is improved.

[0011] The present utility model is further configured as: an installation screw rod is fixedly connected to the bottom of the conversion disk, and a fastening bolt is threadedly sleeved on the surface of the installation screw rod.

[0012] With the above technical solution, it is convenient to install the conversion disk on the output shaft flange of the uncoiler by using the installation screw rod and the fastening bolt.

[0013] The present utility model is further configured as: buffer pads that are bonded to the conversion disk are arranged on both sides inside the limiting chute.

[0014] With the above technical solution, when the inner support rod slides inside the limiting chute and touches the conversion disk, the inner support rod is buffered, thereby reducing vibration and improving the installation stability of the calendered copper foil sleeve.

[0015] The present utility model is further configured as: an anti-slip sleeve is fixedly sleeved on the surface of the inner support rod.

[0016] With the above technical solution, the friction force on the surface of the inner support rod is increased, and the installation stability of the sleeve for calendered copper foil is improved.

[0017] The present utility model is further configured such that: at one end of the first bevel gear away from the inside of the conversion disk and at one end of the double-threaded screw rod away from the inside of the inner support rod, a turntable is fixedly connected.

[0018] Adopting the above technical solution, it is convenient to drive the double-threaded screw rod and the first bevel gear to rotate inside the inner support rod and the conversion disk respectively by twisting the turntable.

[0019] To sum up, the present utility model has the following beneficial effects:

[0020] 1. By sleeving the rolled copper foil sleeve on the surface of the inner support rod, and then controlling the inner support rods to open towards each other, so as to be in contact with the inner ring of the rolled copper foil sleeve, various different models of rolled copper foil sleeves can be fixed on a single model of uncoiler. This improves the practicality of the conversion disk, and at the same time is also convenient for installing the rolled copper foil sleeve, improving the processing efficiency;

[0021] 2. The two limit disks can approach each other to clamp both sides of the rolled copper foil sleeve, so that the rolled copper foil sleeve cannot slide left and right on the surface of the inner support rod. This prevents the copper foil from shifting in position after being stretched from the sleeve, thus facilitating the subsequent processing of the rolled copper foil and improving the practicality.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following further describes the present utility model in detail with reference to the accompanying drawings.

[0029] Example 1:

[0030] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 A sleeve conversion disk for calendered copper foil, comprising a conversion disk 1. A double-sided bevel gear 3 is slidably connected inside the conversion disk 1. One side of the bottom of the double-sided bevel gear 3 meshes with a first bevel gear 2 rotatably connected to the conversion disk 1. Four single-threaded screws 4 are symmetrically and rotatably connected inside the conversion disk 1. One end of each of the four single-threaded screws 4 away from each other is fixedly connected to a second bevel gear 5 meshing with the top of the double-sided bevel gear 3. The surface of the single-threaded screw 4 is threadedly sleeved with a first thread sleeve 6. The top of the first thread sleeve 6 is fixedly connected to an inner support rod 7. A limit chute 18 for slidably connecting with a limit disk 8 is provided at the top of the conversion disk 1. By sleeving the calendered copper foil sleeve on the surface of the inner support rod 7 and then controlling the inner support rods 7 to open outwards, they are in contact with the inner ring of the calendered copper foil sleeve, so that calendered copper foil sleeves of various different models can be fixed on a single model of uncoiler. The practicability of the conversion disk is improved, and at the same time, it is also convenient to install the calendered copper foil sleeve, improving the processing efficiency.

[0031] Reference Figure 4 A ball 14 rotatably connected inside the conversion disk 1 and slidably connected to the double-sided bevel gear 3 is provided to reduce the friction of the double-sided bevel gear 3 sliding inside the conversion disk 1 and improve the sliding stability.

[0032] Reference Figure 2 An installation screw 15 is fixedly connected to the bottom of the conversion disk 1. A fastening bolt 16 is threadedly sleeved on the surface of the installation screw 15, which is convenient to install the conversion disk onto the output shaft flange of the uncoiler by using the installation screw 15 and the fastening bolt 16.

[0033] Brief description of the use process: First, fixedly install the conversion disk 1 on the output shaft of the calendered copper foil uncoiler. Then, by rotating the first bevel gear 2 to mesh with the double-sided bevel gear 3, drive the double-sided bevel gear 3 to rotate inside the conversion disk 1. After the double-sided bevel gear 3 can mesh with the four second bevel gears 5, synchronously drive all the single-threaded screws 4 inside the conversion disk 1 to rotate. Then, through the threaded engagement between the single-threaded screw 4 and the first thread sleeve 6, the inner support rod 7 at the top of the first thread sleeve 6 can slide on the top of the conversion disk 1 under the limitation of the limit chute 18, so that the four inner support rods 7 can open outwards or fold inwards. After controlling the four inner support rods 7 to fold inwards, sleeve the calendered copper foil sleeve on the surface of the four inner support rods 7, and then control the four inner support rods 7 to open outwards, and then they are in contact with the inner ring of the calendered copper foil sleeve, so that it can limit and fix calendered copper foil sleeves of various different models.

[0034] Example 2:

[0035] Reference Figure 1 、 Figure 2 、 Figure 5 , a sleeve conversion disk for calendered copper foil. A double-threaded screw rod 9 is rotatably connected inside an inner support rod 7. Both ends of the surface of the double-threaded screw rod 9 are threadedly sleeved with second thread sleeves 10. Both ends of the surface of the inner support rod 7 near the two second thread sleeves 10 are slidably sleeved with limit disks 8. A guiding chute 11 is formed on the surface of the inner support rod 7. Connection blocks 12 that are slidably connected to the guiding chute 11 are fixedly connected between the second thread sleeves 10 and the limit disks 8; the two limit disks 8 can be close to each other to clamp both sides of the calendered copper foil sleeve, so that the calendered copper foil sleeve cannot slide left and right on the surface of the inner support rod 7. Furthermore, it prevents the copper foil from shifting in position after being stretched from the sleeve, thus facilitating subsequent processing of the calendered copper foil and improving practicality.

[0036] Reference Figure 1 、 Figure 2 , buffer pads 17 bonded to the conversion disk 1 are arranged on both sides inside the limit chute 18. When the inner support rod 7 slides inside the limit chute 18 and touches the conversion disk 1, it buffers the inner support rod 7, thereby reducing vibration and improving the installation stability of the calendered copper foil sleeve.

[0037] Reference Figure 1 、 Figure 2 , an anti-slip sleeve 19 is fixedly sleeved on the surface of the inner support rod 7, increasing the friction on the surface of the inner support rod 7 and improving the installation stability of the sleeve for calendered copper foil.

[0038] Reference Figure 1 、 Figure 4 、 Figure 5 , turntables 13 are fixedly connected to one end of the first bevel gear 2 away from the inside of the conversion disk 1 and one end of the double-threaded screw rod 9 away from the inside of the inner support rod 7, facilitating driving the double-threaded screw rod 9 and the first bevel gear 2 to rotate inside the inner support rod 7 and the conversion disk 1 respectively by twisting the turntables 13.

[0039] Brief description of the usage process: After the calendered copper foil sleeve is limited and fixed by the four inner support rods 7 spreading apart from each other. Then, the double-threaded screw rod 9 is rotated to engage with the second thread sleeve 10 in a threaded manner. Thus, the connection blocks 12 on the surface of the second thread sleeve 10 drive the limit disks 8 to slide on the surface of the inner support rod 7 under the limitation of the guiding chute 11, enabling the two limit disks 8 to clamp both sides of the calendered copper foil sleeve. Furthermore, the calendered copper foil sleeve cannot slide left and right on the surface of the inner support rod 7, preventing the copper foil from shifting in position during stretching.
