Description

Technical Field

[0001] This utility model relates to the field of mica tape reel loading and unloading technology, and in particular to a loading and unloading device for cable production mica tape reels. Background Technology

[0002] A cable is a bundle of wires consisting of one or more mutually insulated conductive metal cores tightly twisted or arranged in parallel, and wrapped in a uniform insulating protective material and outer sheath. Its core function is to efficiently and safely transmit electrical energy or signals. Cables are widely used in many fields such as high-voltage power transmission, building power distribution, communication networks, and internal equipment connections. Through their reliable insulation and protective structure, they ensure a stable power supply and smooth information transmission, acting like the veins of modern society, supporting all aspects from daily life to industrial production.

[0003] During cable manufacturing, existing equipment typically has an eccentric shaft along the output direction of the cable. A locking block on the shaft limits the position of the mica tape reel. Rotating the eccentric shaft causes the mica tape on the reel to wrap around the periphery of the cable, thus forming a uniform, continuous, and tight mica tape wrapping insulation layer, providing the cable with key electrical insulation performance and excellent fire resistance.

[0004] However, in actual use, due to the limited length of mica tape in the mica tape reel, the reel needs to be replaced after the mica tape is wound. The mica tape reel is usually set on an eccentric shaft and limited by a locking block, making the replacement process cumbersome and reducing work efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the limiting block on the eccentric shaft affects the replacement efficiency of the mica tape reel when loading and unloading the mica tape reel in the existing technology, and to propose a loading and unloading device for mica tape reels in cable production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a loading and unloading device for mica reels in cable production, including a mounting plate, a rotating ring rotatably connected to the mounting plate, a turntable fixedly connected to the side of the rotating ring, and a reel loading and unloading assembly. The reel loading and unloading assembly includes two eccentric bushings fixed to the side of the turntable. Two U-shaped clamping plates are symmetrically slidably connected inside the eccentric bushings. Hinges are hinged to the sides of the U-shaped clamping plates. A connecting block is provided between adjacent hinges. A sliding rod is fixedly connected to the connecting block. A drive assembly is fixedly connected to the mounting plate.

[0008] Preferably, a connecting frame is fixedly connected between the two slide rods, and two pull lugs are symmetrically fixedly connected on the connecting frame.

[0009] Preferably, a first baffle is fixedly connected to the periphery of the slide rod, a second baffle is fixedly connected to the inner side of the eccentric bushing, and a spring is fixedly connected between the first baffle and the second baffle.

[0010] Preferably, the drive assembly includes a motor, which is fixedly connected to a mounting plate. A rotating shaft is rotatably connected through the mounting plate. A gear is fixedly connected to the circumferential side of the rotating shaft. The output end of the motor is fixedly connected to the rotating shaft. A gear ring is fixedly connected to the circumferential side of the rotating shaft. The gear and the gear ring mesh with each other.

[0011] Preferably, a disc sleeve is slidably connected to the eccentric bushing, and the disc sleeve abuts against a corresponding U-shaped clamping plate.

[0012] Preferably, the eccentric bushing has a sliding groove on its peripheral side, and the connecting frame slides into the sliding groove.

[0013] Preferably, a top block is fixedly connected to the end of the U-shaped card plate, and the top block is made of rubber.

[0014] Preferably, the eccentric bushing is located at an eccentric position on the turntable.

[0015] The present invention provides a loading and unloading device for mica tape reels in cable production. The advantages of this device are as follows: When in use, the device moves a connecting frame, which in turn moves two sliding rods synchronously. The sliding rods then move a connecting block. Since the connecting block and the U-shaped clamping plate are connected by a hinge, the U-shaped clamping plate extending from the eccentric bushing can be retracted, thereby quickly releasing the restriction on the tape reel and improving the efficiency of loading and unloading mica tape reels.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1

[0025] Reference Figure 1-5 This utility model is a loading and unloading device for mica reels in cable production, including a mounting plate 1, a rotating ring 2 rotatably connected to the mounting plate 1, a turntable 3 fixedly connected to the side of the rotating ring 2, and a reel loading and unloading assembly. The reel loading and unloading assembly includes two eccentric bushings 4, which are fixed to the side of the turntable 3. Two U-shaped clamping plates 5 are symmetrically slidably connected inside the eccentric bushings 4. Hinges 6 are hinged to the side of the U-shaped clamping plates 5. A connecting block 7 is provided between adjacent hinges 6. A sliding rod 8 is fixedly connected to the connecting block 7. A driving assembly is fixedly connected to the mounting plate 1.

[0026] The operation process of this embodiment is as follows: When wrapping the cable mica tape reel, after the cable passes through the mounting plate 1, the drive assembly drives the rotating ring 2 and the turntable 3 to rotate. In the initial state, the tape reel cylinder 18 is sleeved on the surface of the eccentric bushing 4, and both ends are limited by the U-shaped clamping plate 5. After connecting the mica tape on the tape reel cylinder 18 to the cable, as the eccentric bushing 4 continues to rotate along the axis of the cable, the cable continues to be output outward, so that the mica tape can be evenly wrapped on the cable.

[0027] The U-shaped clamp 5 prevents the tape reel 18 from shifting during wrapping, but it can obstruct the removal of the tape reel 18 from the eccentric bushing 4 during loading and unloading of the mica tape reel. Therefore, as Figure 4 As shown, sliding the slide bar 8 to the left causes the connecting block 7 to move. Since the connecting block 7 and the U-shaped clamping plate 5 are connected by the hinge rod 6, as the connecting block 7 moves to the left, both U-shaped clamping plates 5 move toward the axis of the eccentric bushing 4. The U-shaped clamping plates 5 retract into the eccentric bushing 4, thus releasing the restriction on both ends of the tape reel 18. After the mica tape is wrapped in the tape reel 18, sliding the slide bar 8 to the left releases the restriction on the tape reel 18. Sliding the tape reel 18 to the right removes it from the eccentric bushing 4.

[0028] Example 2

[0029] During use, although the slide bar 8 can be moved to adjust the position of the U-shaped clamping plate 5 within the eccentric sleeve 4, the U-shaped clamping plate 5 may move and retract into the eccentric sleeve 4 during the wrapping process, thus losing its limiting effect on the drum 18. Therefore, please refer to [the relevant documentation / reference needed]. Figure 4-5 Based on the first specific embodiment, a connecting frame 9 is fixedly connected between the two sliding rods 8. Two pull ears 13 are symmetrically fixedly connected on the connecting frame 9. A first baffle 10 is fixedly connected to the side of the sliding rod 8. A second baffle 12 is fixedly connected inside the eccentric bushing 4. A spring 11 is fixedly connected between the first baffle 10 and the second baffle 12. A disc cylinder 18 is slidably connected to the eccentric bushing 4. The disc cylinder 18 abuts against the corresponding U-shaped clamping plate 5. A sliding groove 19 is opened on the side of the eccentric bushing 4. The connecting frame 9 and the sliding groove 19 are slidably engaged. A top block 20 is fixedly connected to the end of the U-shaped clamping plate 5. The top block 20 is made of rubber. The eccentric bushing 4 is located at the eccentric position of the turntable 3.

[0030] The operation process in this embodiment is as follows: during the wrapping process, as follows: Figure 4 As shown, the spring 11 always pushes the baffle and slide bar 8 to move to the left, keeping the two U-shaped baffles always outside the eccentric bushing 4. When it is necessary to release the limit on the tape drum 18, slide the slide bar 8, and the connecting block 7 moves to stretch the spring 11. After the new tape drum 18 is replaced, the spring 11 returns to its original position and limits the new tape drum 18. The connecting frame 9 is fixedly connected between the two slide bars 8, and the connecting frame 9 is provided with a pull lug 13. When in use, pulling the pull lug 13 can drive the two slide bars 8 to move synchronously and in the same direction, thereby further improving work efficiency.

[0031] Example 3

[0032] The eccentric bushing 4 needs to rotate at a constant speed to evenly wrap the mica tape around the cable. For this purpose, please refer to [link / reference needed]. Figure 1-2 Based on the first specific embodiment, the drive component includes a motor 14, which is fixedly connected to the mounting plate 1. A rotating shaft 15 is rotatably connected through the mounting plate 1. A gear 16 is fixedly connected to the circumference of the rotating shaft 15. The output end of the motor 14 is fixedly connected to the rotating shaft 15. A toothed ring 17 is fixedly connected to the circumference of the rotating ring 2. The gear 16 and the toothed ring 17 mesh with each other.

[0033] The operation process of this embodiment is as follows: the motor 14 drives the rotating shaft 15 to rotate, the rotating shaft 15 drives the gear 16 to rotate, and since the gear 16 and the gear ring 17 mesh with each other, the gear ring 17 rotates at a constant speed, thereby driving the rotating ring 2 fixed to the gear ring 17 to rotate at a constant speed, which enables the two eccentric bushings 4 to rotate at a constant speed, thereby improving the uniformity of wrapping the mica tape.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
