Description

Technical Field

[0001] This utility model relates to the technical field of light-shielding tape production equipment, and more precisely to a light-shielding tape core fixing device. Background Technology

[0002] Light-shielding tape is a widely used component in the manufacturing process of displays. For example, it can be adhered to the edges of the display screen to reduce light leakage at the edges when the backlight is on, while also providing some degree of stability to the screen edges. Light-shielding tape is used in large quantities during display production and is typically produced and transported in rolls.

[0003] When light-shielding tape is rolled into rolls, a core is required. The tape is then wound around the core before storage and transport. The core needs to remain stable during processing, slitting, or winding, thus requiring a fixing device to secure it. However, since cores come in various diameters, such as 3 inches, 6 inches, and 8 inches, different fixing devices are needed for different diameter cores to achieve stable fixation, resulting in high production costs, cumbersome operation, and low efficiency.

[0004] In the existing technology, the take-up shaft diameter of the winding machine is fixed at 3 inches. Therefore, when producing roll products, a 3-inch core is first used for winding, and after inspection, a 6-inch or 8-inch core is used for rewinding. Moreover, the rewinding process requires manual operation, which makes the winding operation of light-blocking tape cumbersome, inefficient, and prone to operational errors.

[0005] In summary, there is a need in this field for a fixing device that can be adapted to tube cores of different diameters, so as to complete the winding operation of light-shielding tape conveniently and efficiently. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a light-shielding tape core fixing device, which uses an elastic sheet and a tension structure set on the central rod to support and fix the core sleeved on the outside of the central rod, thereby adapting to cores of different sizes.

[0007] To achieve the above objectives, this utility model provides a light-shielding tape core fixing device, including a central rod, an adjusting component, and several elastic plates. The central rod has a rotating shaft at each end, and rows of receiving grooves are evenly distributed on the side wall of the central rod. Each row of receiving grooves includes several evenly arranged receiving grooves. The elastic plates are respectively installed in the receiving grooves. The adjusting component is connected to the central rod and the rotating shaft, and passes through the central rod to be drivenly connected to one end of each elastic plate. By operating the adjusting component to change the height of the elastic plate protruding from the receiving groove, the elastic plate abuts against the inner wall of the core surrounding the central rod, thereby supporting and fixing the core.

[0008] Preferably, one end of the elastic sheet is fixedly connected to the bottom edge of the receiving groove, and the other end is drivenly connected to the adjustment component.

[0009] Preferably, the adjustment assembly includes an adjustment ring, several pull ropes, and an adjustment bolt. The adjustment ring is slidably sleeved on a rotating shaft. One end of each pull rope is fixedly connected to the adjustment ring, and the other end slidably passes through the central rod and through a row of receiving slots. The end of each elastic piece in the receiving slot is fixedly connected to the pull rope, and the elastic piece furthest from the adjustment ring is fixedly connected to the end of the pull rope. The adjustment bolt is rotatably connected to the end of the central rod. The adjustment bolt is parallel to the rotating shaft and threadedly connected to the adjustment ring. Rotating the adjustment bolt causes the adjustment ring to move along the axial direction of the rotating shaft.

[0010] Preferably, the end of the adjusting bolt has a bolt head.

[0011] Preferably, the adjustment assembly includes a plurality of guide rods, the guide rods being fixedly connected to the ends of the central rod, and the guide rods being parallel to the rotating shaft, and the guide rods being slidably passing through the adjustment ring.

[0012] Preferably, the adjustment assembly includes two guide rods symmetrically arranged with respect to the axis of rotation.

[0013] Preferably, the end of the guide rod away from the center rod has a limiting head.

[0014] Preferably, each row of the receiving slots includes 3 or 4 receiving slots.

[0015] Compared with the prior art, the advantages of the light-shielding tape core fixing device disclosed in this utility model are as follows: the light-shielding tape core fixing device can adapt to cores of different sizes and supports a stable fixation without the need for winding and rewinding operations, simplifying the winding operation and improving winding efficiency; the elastic sheet of the light-shielding tape core fixing device expands synchronously to ensure the coaxiality of the central rod and the core, achieving uniform support for the core and effectively avoiding uneven tension or wrinkles of the light-shielding tape during winding due to eccentric rotation of the core; the light-shielding tape core fixing device can control the elastic sheet to retract and reset after winding, making it easy to remove the core after wrapping with light-shielding tape.

[0020] 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.

[0021] like Figures 1 to 3As shown, this application discloses a light-shielding tape core fixing device, comprising a central rod 1, an adjusting assembly, and several elastic plates 3. The central rod 1 has rotating shafts 11 at both ends. Four rows of receiving grooves are evenly distributed on the side wall of the central rod 1. Each row of receiving grooves includes several evenly arranged receiving grooves 10. The elastic plates 3 are respectively installed in the receiving grooves 10. The adjusting assembly is connected to the central rod 1 and the rotating shafts 11, and the adjusting assembly passes through the central rod 1 and is connected to one end of each elastic plate 3 via a transmission connection. By operating the adjusting assembly, the height of the elastic plate 3 protruding from the receiving groove 10 is changed, causing the elastic plate 3 to abut against the inner wall of the core 4 surrounding the central rod 1, thereby supporting and fixing the core 4. Utilizing the characteristics of the elastic plate 3, the light-shielding tape core fixing device can adapt to cores of different sizes and provides stable fixing without the need for rewinding, simplifying the winding operation and improving winding efficiency.

[0022] Specifically, each row of receiving slots includes 3 to 4 receiving slots 10 to reduce the force required for adjustment while providing sufficient support.

[0023] One end of the elastic sheet 3 is fixedly connected to the bottom edge of the receiving groove 10, and the other end is connected to the adjustment component for transmission. The elastic sheet 3 protrudes outward from the receiving groove 10.

[0024] The rotating shaft 11 is used to connect with the machine body, so that the machine body drives the central rod 1 to rotate through the rotating shaft 11, which in turn drives the core 4 to rotate.

[0025] The adjustment assembly includes an adjustment ring 21, several pull ropes 22, and an adjustment bolt 231. The adjustment ring 21 is slidably sleeved on a rotating shaft 11. One end of the pull rope 22 is fixedly connected to the adjustment ring 21, and the other end slidably passes through the central rod 1 and through a row of receiving slots. The end of the elastic piece 3 in the receiving slot is fixedly connected to the pull rope 22, and the elastic piece 3 furthest from the adjustment ring 21 is fixedly connected to the end of the pull rope 22. The adjustment bolt 231 is rotatably connected to the end of the central rod 1. The adjustment bolt 231 is parallel to the rotating shaft 11 and is threadedly connected to the adjustment ring 21. When the adjustment bolt 231 is rotated, it drives the adjustment ring 21 to move along the axial direction of the rotating shaft 11. Depending on the direction of rotation, the adjustment ring 21 is driven to move away from or closer to the central rod 1. When the adjusting ring 21 moves away from the center rod 1, it pulls the traction rope 22, causing the elastic plate 3 to bulge upwards. The different bulge heights are used to adapt to different sizes of tube cores 4. When the adjusting ring 21 moves closer to the center rod 1, the traction rope 22 is no longer under tension, the elastic plate 3 returns to its original position and contracts, releasing the fixation of the tube core 4.

[0026] As can be seen, the elastic sheet 3 can expand synchronously to ensure the coaxiality of the central rod 1 and the tube core 4, thereby achieving uniform support for the tube core 4 and effectively preventing uneven tension or wrinkles of the light-shielding tape during winding due to eccentric rotation of the tube core 4. The light-shielding tape tube core fixing device can control the elastic sheet 4 to shrink and reset after winding, making it easy to pick up the tube core 4 after it is wrapped with light-shielding tape.

[0027] Specifically, the adjustment assembly also includes several guide rods 232. The guide rods 232 are fixedly connected to the ends of the central rod 1 and are parallel to the rotating shaft 11. The guide rods 232 slidably pass through the adjustment ring 21 to guide the movement of the adjustment ring 21, preventing it from tilting during sliding and avoiding uneven tension on the four tension ropes due to tilt, which would cause inconsistent arching heights of the four rows of elastic plates. Preferably, the adjustment assembly includes two guide rods 232 symmetrically arranged relative to the rotating shaft. The ends of the guide rods 232 away from the central rod 1 have limiting heads to prevent the adjustment ring 21 from detaching.

[0028] The end of the adjusting bolt 231 has a bolt head 2311, which allows the operator to easily perform adjustments. Alternatively, the operator can use corresponding equipment to connect with the bolt head 2311 for operation.

[0029] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
