Description

Technical Field

[0001] The invention belongs to the technical field of cable manufacturing, and in particular relates to a manufacturing process for an ultra-flexible flame-retardant, low-smoke, environmentally friendly cable. Background Art

[0002] Ultra-flexible flame-retardant, low-smoke, environmentally friendly cables are made by replacing the traditional flexible cables with green insulation materials. By using insulation materials that do not produce harmful substances when burned and flame retardants and do not contain halogens, the cables do not emit toxic gases during daily operation, achieving a green and environmentally friendly effect.

[0003] Therefore, when manufacturing cables, the insulation layer needs to be protected. By wrapping a waterproof layer around the outside of the insulation layer, the insulation layer and conductor can be moisture-proofed to extend the service life of the cable.

[0004] However, in the prior art, when wrapping the waterproof tape, a unidirectional spiral winding is usually performed along the axis of the conductor, which easily causes the waterproof tape to loosen and detach, resulting in a poor wrapping effect. In addition, due to the high flexibility of the cable, the cable is prone to eccentric swing during the wrapping process, making it impossible for the waterproof tape to remain taut at all times during the wrapping process, resulting in a poor wrapping effect.

[0032] In step S4, a wrapping device is used to wrap the waterproof tape 321 around the conductor 9;

[0033] The wrapping device includes a base 1, a circular wrapping chamber 11 is provided on the outer wall of the base 1, a front annular groove 12 and a rear annular groove 13 are provided on the inner wall of the wrapping chamber 11 in the axial direction, the front annular groove 12 and the rear annular groove 13 are connected, a guide block 5 is rotatably inserted on the inner wall of the transition between the front annular groove 12 and the rear annular groove 13, a magnet 51 is bonded on the end wall of the guide block 5, and the magnet 51 can be adsorbed on the inner side wall of the front annular groove 12 and the rear annular groove 13, a gear ring 2 is rotatably inserted on the end wall of the base 1, an axial bracket 21 extending into the wrapping chamber 11 is welded on the inner ring wall of the gear ring 2, a radial bracket 22 is slidably inserted on the outer wall of the axial bracket 21, and the radial bracket 22 A sliding column 221 is welded on the bottom outer wall, and the sliding column 221 is adapted to the front ring groove 12 and the rear ring groove 13. In the initial state, the sliding column 221 is slidably inserted in the front ring groove 12, and the sliding column 221 is adapted to the guide block 5. A floating block 3 is slidably inserted on the outer wall of the radial bracket 22, and a feeding wheel 32 is rotatably inserted on the outer wall of the floating block 3. A tensioning mechanism is provided on the radial bracket 22, a motor 6 is welded on the outer wall of the base 1, and a gear 61 is welded on the main shaft of the motor 6. The gear 61 is meshed with the ring gear 2, and guide frames 24 are welded on the outer walls of both ends of the axial bracket 21, and a number of universal wheels 241 are rotatably inserted on the inner wall of the guide frame 24.

[0034] The guide frame 24 is coaxially distributed with the gear ring 2. The guide frame 24 can support the winding part of the conductor 9, thereby reducing the eccentricity tendency of the conductor 9, and further improving the winding effect to a certain extent. The wound conductor 9 is rolled by the universal wheel 241, and can achieve a full circle effect to a certain extent.

[0035] The initial state is Figure 2 As shown, the magnet 51 is attracted to the inner wall of the rear annular groove 13 , so that the guide block 5 is rotated into the front annular groove 12 .

[0036] The above content is further elaborated: during operation, the conductor 9 is passed through the guide frame 24, and the free end of the waterproof tape 321 is manually wound around the outer wall of the conductor 9 located between the two guide frames 24. Then, the motor 6 is started and the conductor 9 is wound from the side where the gear 61 is located through the winding device not shown in the figure. The motor 6 drives the ring gear 2 to rotate through the gear 61, so that the ring gear 2 drives the axial bracket 21, the radial bracket 22 and the floating block 3 to rotate. As the ring gear 2 rotates, the radial bracket 22 drives the slide post 221 to slide along the front annular groove 12. At the same time, the floating block 3 drives the loading wheel 32 to rotate around the conductor 9, so as to achieve the effect of winding the waterproof tape 321 around the conductor 9 in one direction. After winding one circle, the slide post 221 moves along the front annular groove 12 to the position of the guide block 5. Figure 2As shown, under the action of the guide block 5, the slide post 221 will slide along the guide block 5 into the rear annular groove 13, and at the same time, the slide post 221 pushes away the magnet 51, so that it is adsorbed on the inner wall of the front annular groove 12, and the guide block 5 rotates into the rear annular groove 13. After the slide post 221 enters the rear annular groove 13, it drives the radial bracket 22 to move along the axial bracket 21, and then the radial bracket 22 drives the feeding wheel 32 to move along the axial direction of the conductor 9, so that the waterproof belt 321 is cross-wound, so that the waterproof belt 321 is rewound around the already wound part of the conductor 9 again. When the slide post 221 rotates one circle and returns to the position of the guide block 5 again, the slide post 221 will enter the front annular groove 12 along the guide block 5, and at the same time, the guide block 5 switches its position again, and so on and so forth, so as to achieve the effect of cross-winding the waterproof belt 321 on the conductor 9, so that the waterproof belt 321 is wound more tightly to avoid looseness.

[0037] Specifically, the tensioning mechanism includes a floating frame 4, a radial bracket 22 is located on the outer wall above the floating block 3 and is slidably sleeved with the floating frame 4, a tensioning wheel 23 is rotatably inserted on the top outer wall of the radial bracket 22, a lever 43 extending toward the tensioning wheel 23 is welded on the outer wall of the floating frame 4, a clamping block 44 is welded on the outer wall of the lever 43, the clamping block 44 is adapted to the tensioning wheel 23, a waterproof belt 321 is wrapped around the outer wall of the feeding wheel 32, the free end of the waterproof belt 321 passes through between the tensioning wheel 23 and the feeding wheel 32, between the tensioning wheel 23 and the clamping block 44 in turn, and then passes through from the bottom of the lever 43 and is wrapped around the conductor 9, and a waterproof belt 321 is welded on the outer wall of the side of the floating block 3 away from the feeding wheel 32 A threaded sleeve 33 is connected, and a wedge block 27 is movably connected to the threaded sleeve 33 through threaded cooperation. A coil spring 71 is welded between the outer wall of the wedge block 27 and the inner wall of the threaded sleeve 33. A wedge block 1 323 is welded on the outer wall of the rotating shaft of the feeding wheel 32. The wedge block 1 323 is rotatably inserted in the threaded sleeve 33. The wedge block 1 323 is adapted to the wedge block 27. A bevel rack 41 is welded on the outer wall of the floating frame 4. An incomplete ratchet 322 is welded on the outer wall of the main shaft of the feeding wheel 32. A spring 2 42 is welded between the outer wall of the floating frame 4 and the outer wall of the floating block 3. The incomplete ratchet 322 is unidirectionally meshed with the bevel rack 41. A spring 1 31 is welded between the outer wall of the floating block 3 and the outer wall of the radial bracket 22.

[0038] By means of the provided spring 1 31 , the feeding wheel 32 and the tensioning wheel 23 are always kept in contact with each other, so that the tensioning wheel 23 can squeeze the waterproof belt 321 wound on the feeding wheel 32 to prevent it from loosening.

[0039] In the initial state, the wedge block 2 7 abuts against the wedge block 1 323, and the coil spring 71 is in a natural state.

[0040] The above tensioning mechanism is further explained as follows: when working, the feeding wheel 32 revolves with the gear ring 2, and at the same time rotates under the pull of the waterproof belt 321 wrapped around the conductor 9. When the feeding wheel 32 rotates, it drives the incomplete ratchet 322 to rotate, so that the incomplete ratchet 322 can move the inclined rack 41 upward, so that the floating frame 4 drives the clamping block 44 to approach the tensioning wheel 23 and clamp the waterproof belt 321, so that the waterproof belt 321 is tightened. When the incomplete ratchet 322 is separated from the inclined rack 41, under the action of the spring 42 The floating frame 4 drives the clamping block 44 to move downward to loosen the waterproof belt 321, and this reciprocating process is used to achieve the effect of intermittently tightening the waterproof belt 321 to prevent the waterproof belt 321 from loosening and causing the winding to be loose. In addition, the feeding wheel 32 rotates to release the waterproof belt 321 and drives the wedge block 1 323 to rotate, so that the wedge block 1 323 drives the wedge block 2 7 to compress the coil spring 71 to rotate, and under the action of the threaded cooperation, the wedge block 2 7 gradually moves away from the wedge block 1 323 during the rotation process, until the wedge block 2 7 moves away from the wedge block 1 323, when the conductor 9 is in contact with the feeding wheel 32 When the waterproof belt 321 between the wheels 32 is not kept tight due to the eccentric swing of the conductor 9, the waterproof belt 321 is in a loose state and does not pull the feeding wheel 32 to rotate. At this time, the compressed coil spring 71 is released, and the coil spring 71 drives the wedge block 2 7 to rotate in the opposite direction. The wedge block 2 7 rotates in the opposite direction and approaches the wedge block 1 323 along the threaded sleeve 33. When the wedge block 2 7 abuts against the wedge block 1 323, the wedge block 2 7 drives the feeding wheel 32 to rotate in the opposite direction, so that the feeding wheel 32 can reel in the loose waterproof belt 321, and then the conductor 9 and the upper The waterproof belt 321 between the material wheels 32 resumes the tensioned state again, achieving the effect of improving the winding tightness of the waterproof belt 321. At the same time, the feeding wheel 32 rotates in the opposite direction with the incomplete ratchet 322, so that the incomplete ratchet 322 engages with the bevel rack 41. At this time, the floating frame 4 drives the lever 43 to move downward, so that the lever 43 can pull the waterproof belt 321 down and tension it, further improving the anti-loosening effect. After the engagement stroke of the incomplete ratchet 322 and the bevel rack 41 is completed, under the action of the spring 2 42, the bevel rack 41 drives the floating frame 4 to move up and reset.

[0041] Supplementary explanation: When wedge block 2 7 moves to a disengaged state with wedge block 1 323, under the action of coil spring 71, wedge block 2 7 will reverse and abut against wedge block 1 323 again. However, since the waterproof belt 321 pulls the loading wheel 32 to rotate, wedge block 1 323 will again drive wedge block 2 7 to rotate to a disengaged state, and so on. The coil spring 71 always remains in a compressed state until the waterproof belt 321 relaxes and no longer pulls the loading wheel 32 to rotate, and then the elastic force is released.

[0042] The working principle and use process of the present invention are as follows: during operation, the conductor 9 is passed through the guide frame 24, and the free end of the waterproof tape 321 is manually wound around the outer wall of the conductor 9 located between the two guide frames 24. Then, the motor 6 is started and the conductor 9 is wound from the side where the gear 61 is located through the winding device not shown in the figure. The motor 6 drives the gear ring 2 to rotate through the gear 61, so that the gear ring 2 drives the axial support 21, the radial support 22 and the floating block 3 to rotate, and the floating block 3 drives the loading wheel 32 to rotate around the conductor 9, so as to achieve the effect of winding the waterproof tape 321 around the conductor 9 in one direction. Under the action of the guide block 5, the slide column 221 can switch the trajectory along the front annular groove 12 or the rear annular groove 13 every time it rotates one circle, so that the radial support 22 drives the loading wheel 32 to reciprocate along the axial direction of the conductor 9, and then the waterproof tape 321 is wound around the wound part of the conductor 9 again, and so on and so forth, so as to achieve the effect of cross-winding the waterproof tape 321 around the conductor 9, so that the waterproof tape 321 The winding is tighter to avoid looseness. At the same time, under the action of the tensioning mechanism, the incomplete ratchet 322 can intermittently move the bevel rack 41 upward, so that the floating frame 4 drives the clamping block 44 to approach the tensioning wheel 23 and clamp the waterproof belt 321, so as to achieve the effect of intermittently tightening the waterproof belt 321, and avoid the situation that the waterproof belt 321 is loose and causes the winding to be loose. When the waterproof belt 321 is loose, the compressed coil spring 71 is released, so that the wedge block 27 drives the feeding wheel 32 to reverse The loading wheel 32 rotates in the opposite direction, so that the loading wheel 32 can reel in the loosened waterproof tape 321, and then the waterproof tape 321 between the conductor 9 and the loading wheel 32 resumes the tensioned state again, thereby achieving the effect of improving the winding tightness of the waterproof tape 321. At the same time, the loading wheel 32 rotates in the opposite direction with the incomplete ratchet 322, so that the incomplete ratchet 322 engages with the bevel rack 41. At this time, the floating frame 4 drives the lever 43 to move downward, so that the lever 43 can pull the waterproof tape 321 down and tension it, further improving the anti-loosening effect.
