Description

Technical Field

[0001] The utility model relates to the technical field of power cable production, in particular to an external insulation wrapping device for power cables. Background Art

[0002] The basic structure of power cable consists of four parts: core (conductor), insulation layer, shielding layer and protective layer. The device that wraps the outer side of the power cable with an insulation layer actually wraps the tape around the outer side of the core. The tape winding process is also called the wrapping process.

[0003] When the power cable is being wrapped, the tape needs to be properly tensioned to be better wrapped around the cable. The rolled tape will be continuously used and consumed during the winding process, so the diameter of the tape roll is decreasing, causing the tension of the tape to continuously change. If the tension of the tape is not enough, the wrapping effect wrapped around the outside of the cable will become too tight or too loose. However, it is not convenient to stop the device and adjust it before working during the wrapping process, which affects the wrapping processing efficiency. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] Figure 1-Figure 5 This is an embodiment of the utility model: an external insulation wrapping device for a power cable, comprising a base 1, a support plate 2 is fixed on the base 1, a wire drum 3 is connected and installed on the support plate 2, a plurality of balls 301 are installed at both ends of the wire drum 3, the cable passes through the wire drum 3 and the balls 301 can reduce the friction between the cable and the wire drum 3, so that the cable can move in the wire drum 3, a turntable 4 is rotatably connected to the support plate 2, a circular groove is opened on the turntable 4 corresponding to the wire drum 3, the turntable 4 can be sleeved on the outside of the wire drum 3, a wrapping tape reel 5 for wrapping the cable is installed on the turntable 4, a quick assembly mounting structure 6 is provided between the wrapping tape reel 5 and the turntable 4, an adjusting mechanism 7 for adjusting the tension of the wrapping tape is installed on the turntable 4, and lifting structures 8 for preventing the cable from falling to the ground are installed on both sides of the adjusting mechanism 7, and a driving mechanism 9 for driving the turntable 4 to rotate for wrapping is installed on the support plate 2.

[0026] The adjusting mechanism 7 comprises two rollers 701 arranged at the lower side of the tape roll 5, the rollers 701 are rotatably connected to the turntable 4, and rollers 702 slidably connected to the turntable 4 are arranged between the rollers 701, a T-shaped slider 703 is fixed on the rollers 702, a slide groove for use with the slider 703 is provided on the turntable 4, a spring 704 is fixed in the slide groove, and the other end of the spring 704 is fixedly connected to the slider 703, and the tape roll 5 and the adjusting mechanism 7 are symmetrically arranged in two groups on the turntable 4. Before wrapping, the two groups of tape rolls 5 are pulled out for a certain length, and the tape first passes over the roller 1 701 below the tape roll 5, then passes through the right side of the roller 2 702, and then passes through the left side of the roller 1 701 at the lower left, and then sticks to the power cable, and then the turntable 4 is driven to rotate by the action of the driving mechanism 9, so that the tape roll 5 continuously releases the tape to wrap the cable. In the continuous working process, the tape on the tape roll 5 is continuously consumed, so that the tension of the tape will become loose. After the tension of the tape becomes loose, the slider 703 is driven to move to the right under the action of the spring 704, thereby moving the roller 2 702 to the right as well, so that the tension of the tape can be restored to a tight state. When the tension of the tape is too tight, the tape can pull the roller 2 702 to move to the left, so that the tension of the tape becomes a little loose. Therefore, during the wrapping process, the mechanism can always maintain a suitable tight state without manual adjustment.

[0027] In this embodiment, the driving mechanism 9 includes a gear 1 901 fixedly connected to the turntable 4, a gear 2 902 rotatably connected to the support plate 2 is provided below the gear 1 901, a rotating shaft is fixed to the gear 2 902, and a motor 903 for driving the rotating shaft to rotate is installed on the support plate 2. When wrapping, the motor 903 drives the gear 2 902 to rotate, and the gear 1 901 can be driven to rotate through the gear transmission, so that the turntable 4 rotates and the wrapping tape is wound around the outside of the cable to wrap.

[0028] In this embodiment, the lifting structure 8 includes a bracket 801 fixed on the base 1, and a supporting wheel 802 is rotatably connected to the bracket 801. During the wrapping process, the cable passes through the wire drum 3. In order to prevent the cable from being too loose and falling to the ground, the cable is placed on the tug and lifted.

[0029] Example 2

[0030] Based on Example 1, Figure 1-Figure 4As shown, the installation structure 6 includes a sleeve 601 rotatably connected to the tape roll 5, an L-shaped slot 602 is provided on the sleeve 601, a pin 603 is fixed on the turntable 4, and two limit rods 604 adapted to the slot 602 are fixed on the pin 603. When the tape roll 5 is used up and replaced, the sleeve 601 on the tape roll 5 is aligned with the pin 603 on the turntable 4, and then the tape roll 5 is rotated so that the limit rod 604 is stuck in the innermost side of the slot 602, so that the tape roll 5 can be quickly installed.

[0031] The specific implementation process of this embodiment is as follows: the cable passes through the wire drum 3, and the cable can be lifted by the support wheel 802 to prevent it from dragging on the ground. Before processing, the tape roll 5 is first installed on the turntable 4, and the sleeve 601 on the tape roll 5 is aligned with the pin 603 and rotated so that the limit rod 604 on the pin 603 can be rotated and stuck into the innermost side of the card slot 602, thereby completing the assembly of the tape roll 5, and then the tape passes over the roller 1 701 close to the tape roll 5, and then goes around to the right side of the roller 2 702, and then goes around from the right side of the roller 2 702 to the left side of the roller 1 701 below, and then the tape is glued to the cable, and then the motor 903 is started to drive the gear 2 902 to rotate. The gear 901 is driven to rotate through the gear transmission, thereby driving the turntable 4 to rotate, and the tape on the tape roll 5 is rotated to wrap around the outside of the cable, thereby performing the wrapping process. During the wrapping process, the tape is continuously reduced, so that the tension between the tape and the cable becomes loose. After the tension of the tape becomes loose, the slider 703 and the roller 2 702 are driven to move to the right under the action of the spring 704, so that the tension of the tape can be restored to a tight state. When the tension of the tape is too tight, the tape can pull the roller 2 702 to move to the left, so that the tension of the tape becomes a little loose. Therefore, during the wrapping process, the mechanism can always maintain a suitable tight state without manual adjustment.
