Technical Field

[0001] The utility model relates to the technical field of longitudinal wrapping of water-blocking tapes, in particular to a longitudinal wrapping device of water-blocking tapes. Background Art

[0002] The water-blocking function of the water-blocking tape is mainly due to the highly absorbent material (called water-blocking agent) that swells when it comes into contact with water. When the water-blocking agent encounters water, it can expand rapidly to form a large volume of colloid, thereby preventing water from continuing to penetrate and diffuse.

[0003] In the process of producing water-blocking cables, a longitudinal wrapping device is required. The longitudinal wrapping device can wrap the water-blocking tape longitudinally on the outer surface of the cable. Since the side of the water-blocking tape in contact with the cable has an adhesive, when the water-blocking tape is unwound, the side with the adhesive faces upward and is exposed to the air, causing impurities such as hair and fiber to be easily adhered to the adhesive on the water-blocking tape and wrapped around the cable, affecting the quality of the cable.

DETAILED DESCRIPTION

[0018] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0019] like Figure 1-5As shown, a water-blocking tape longitudinal wrapping device includes a reeling device and a wrapping device, the reeling device includes a bottom plate 1, a vertical plate 2 is arranged on the bottom plate 1, a rotating shaft 3 is arranged on the vertical plate 2, a motor 4 for driving the rotating shaft 3 to rotate is arranged on one side of the vertical plate 2, a positioning plate 5 and a movable plate 6 are arranged on the rotating shaft 3, a water-blocking tape 7 is installed on the rotating shaft 3 and is between the positioning plate 5 and the movable plate 6, a first nut 8 for pressing the movable plate 6 is threadedly connected on the rotating shaft 3, a mounting groove 9 is arranged on the vertical plate 2, a fixed shaft 10 is rotatably connected to the mounting groove 9, and the wrapping device includes a fixing frame 11 arranged on one side of the bottom plate 1, and a guide groove 12 is arranged on the fixing frame 11 , one end of the water-blocking tape 7 passes around the fixed shaft 10 and enters the guide groove 12, and also includes a cover plate 13, the lower end and both ends of the cover plate 13 are opened, one end of the cover plate 13 is rotatably connected to the fixed shaft 10, and the other end of the cover plate 13 is provided with a support frame 14, and the support frame 14 is placed on the upper surface of the guide groove 12, and a second nut 15 for fixing the cover plate 13 is threadedly connected to the fixed shaft 10, and a notch is opened on the upper surface of the cover plate 13 at one end close to the second nut 15, and a rotatable top plate 16 is arranged in the notch of the cover plate 13, and a guide ring 17 is arranged inside the cover plate 13 and below the notch, and the guide ring 17 is rotatably connected to the cover plate 13.

[0020] The positioning plate 5 is fixedly connected to the rotating shaft 3. When the rolled water-blocking tape 7 is installed, one end of the water-blocking tape 7 is abutted against the positioning plate 5, and then the movable plate 6 is put on the rotating shaft 3. Then, the first nut 8 on the rotating shaft 3 is rotated, and the movable plate 6 is continuously squeezed by the rotation of the first nut 8, so that the water-blocking tape 7 is fixed between the fixed plate and the movable plate 6. When in use, the unwinding speed of the water-blocking tape 7 needs to be controlled according to the moving speed of the cable. Specifically, the rotation of the rotating shaft 3 is controlled by the motor 4 to control the unwinding speed of the water-blocking tape 7.

[0021] The cable is located above the water-blocking tape 7 and passes through the guide groove 12. After the movable end of the water-blocking tape 7 passes around the fixed shaft 10, it is first manually wrapped and bonded to the outer surface of the cable. During the subsequent movement of the cable, the motor 4 rotates to enable the water-blocking tape 7 to follow the movement of the cable. After the water-blocking tape 7 passes through the guide groove 12, it will gradually and automatically wrap around the outer surface of the cable, thereby achieving the coating of the cable.

[0022] A torsion spring 24 is arranged between the top plate 16 and the cover plate 13. Under the action of the torsion spring 24, the top plate 16 can be flipped to the outside of the cover plate 13. When the cable passes through the unwound water-blocking tape 7, the cover plate 13 and the top plate 16 can shield the top and both sides of the water-blocking tape 7, so as to prevent external impurities such as hair and fibers from falling onto the water-blocking tape 7. When the cable passes through the water-blocking tape 7, the cable needs to pass through the guide ring 17 first, and then through the guide groove 12. Through the guide ring 17 and the guide groove 12, when the cable is located in the area between the guide ring 17 and the guide groove 12, a closer distance can be maintained between the cable and the water-blocking tape 7, so as to prevent the water-blocking tape 7 from wrapping around the cable poorly due to the uncontrolled distance between the cable and the water-blocking tape 7.

[0023] When it is necessary to manually wrap the movable end of the water-blocking tape 7 around the cable, it is first necessary to loosen the second nut 15 so that the cover 13 on the fixed shaft 10 can be flipped freely, and then flip the cover 13 to a certain angle so that the cover 13 cannot block the area between the fixed shaft 10 and the guide groove 12. After the cover 13 is flipped, the second nut 15 on the fixed shaft 10 is tightened to fix the cover 13. During the flipping process of the cover 13, the base plate 1 will flip after contacting the cable, thereby preventing the cable from bending significantly, while also ensuring that the cover 13 can complete the flipping normally.

[0024] Furthermore, a sleeve 18 is provided on the fixed shaft 10, and the sleeve 18 is rotatably connected to the fixed shaft 10. The width of the sleeve 18 is greater than the width of the water-blocking tape 7, so that the water-blocking tape 7 can be fully unfolded on the sleeve 18. The sleeve 18 can reduce the friction between the fixed shaft 10 and the water-blocking tape 7, prevent the water-blocking tape 7 from being extended to a large extent due to the large friction, and avoid the water-blocking tape 7 from shrinking after being wrapped on the cable.

[0025] Furthermore, limit blocks 19 are provided at both ends of the sleeve 18, and the limit blocks 19 are fixedly connected to the sleeve 18. The limit blocks 19 can prevent the water blocking tape 7 from separating from the sleeve 18. At the same time, the limit blocks 19 and the sleeve 18 rotate synchronously. When the water blocking tape 7 contacts the limit blocks 19, the relative speeds therebetween are approximately the same, thereby reducing the friction during contact and avoiding friction damage to the water blocking tape 7.

[0026] Furthermore, a detachable compression block 20 is provided on the rotating shaft 3, and the compression block 20 is located between the movable plate 6 and the first nut 8. When the first nut 8 is tightened on the rotating shaft 3, the movable block can continuously squeeze the water-blocking tape 7 by continuously pressurizing the compression block 20, thereby avoiding the first nut 8 from loosening and affecting the rotation stability of the water-blocking tape 7.

[0027] Furthermore, an air cavity 21 is provided at the upper end of the cover plate 13, and an air outlet 22 is provided at the lower end surface of the air cavity 21. A through groove matching the air outlet 22 is opened on the upper surface of the cover plate 13, and a high-pressure air duct 23 is provided on the upper surface of the air cavity 21. High-pressure gas enters the air cavity 21 through the high-pressure air duct 23 and is blown to the guide groove 12 through each air outlet 22. When the water-blocking tape 7 passes through the guide groove 12, the high-pressure gas blown out by the air outlet 22 enables the water-blocking tape 7 to adhere to the inner surface of the guide groove 12, so that the water-blocking tape 7 can better follow the guidance of the guide groove 12 to move, thereby improving the coating quality of the water-blocking tape 7 and the cable, and after the high-pressure air encounters the water-blocking tape 7, the air pressure between the cover body and the water-blocking tape 7 is relatively high, which can also prevent impurities such as hair and fibers from entering between the cover plate 13 and the water-blocking tape 7.

[0028] The device can shield the top and both sides of the water blocking tape 7 by the set cover plate 13, thereby preventing impurities such as hair fibers from falling on the water blocking tape 7, and by blowing high-pressure gas to the water blocking tape 7 passing through the guide groove 12 area, the water blocking tape 7 can move stably along the guide groove 12, and can also further prevent impurities such as hair fibers from falling on the water blocking tape 7, thereby improving the coating quality of the water blocking tape 7 and the cable, and improving the quality of the product.
