Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flexible fireproof cable production, in particular to a production line for flexible fireproof cable. BACKGROUND

[0002] Flexible fireproof cable is widely used in power engineering. The production line for fireproof cable generally includes the following processes: preparing copper conductor, preparing cable core, filling fireproof material around the periphery of the cable core, wrapping mica tape on the outer surface of the fireproof filling layer, wrapping fine copper wire braid layer on the outer surface of the mica tape wrapping layer, and wrapping sheath layer on the outer surface of the fine copper wire braid layer. For example, a preparation method of high-flexibility fireproof cable is disclosed in Chinese authorized patent CN105761839B.

[0003] The fireproof material wrapped around the cable core is usually fireproof clay, which can play a role in flame retardation. After wrapping the fireproof clay on the outer surface of the cable, the fireproof clay needs to be wrapped by an insulation layer. The wrapping method usually adopts mica tape winding, which can not only enhance the insulation performance of the cable itself, but also stabilize the fireproof clay to prevent it from falling off and deforming.

[0004] In the normal process, the fireproof clay is in a soft state after wrapping. If the mica tape is wrapped too tightly around the outer wall of the fireproof clay, the fireproof clay is excessively squeezed, and the density of the fireproof clay accumulated on the outer surface of the cable core is high, which leads to poor heat dissipation performance of the flexible fireproof cable. Moreover, when the cable core is wrapped with an equal amount of fireproof clay, the thickness of the fireproof clay layer is insufficient, and the cable core is easily exposed when damaged by external factors, causing safety accidents. If the mica tape is wrapped too loosely, the amount of mica tape used increases, and gaps are easily generated between the inner part of the mica tape and the outer layer of the fireproof clay. During the subsequent processing of the cable, the mica tape is prone to misalignment and loosening, affecting the quality of the flexible cable. SUMMARY

[0035] The rotating seat 21 drives the two sides of the installation shaft 3 to rotate in the process of rotation, the installation shaft 3 drives the telescopic push rod 6 to rotate at the same time, the telescopic push rod 6 can adjust the arc-shaped plate 61 to make the arc-shaped plate 61 can be adjusted to the appropriate position, the telescopic end of the telescopic push rod 6 drives the arc-shaped plate 61 provided at the end to move along the outer wall of the cable core 9, the arc-shaped plate 61 supports and limits the cable core 9, so that the cable core 9 can pass through the hole more stably and accurately, in the process of rotation of the arc-shaped plate 61, the arc-shaped plate 61 can rotate along the outer wall of the cable core 9, can extrude the outer wall of the cable core 9, so that the fire clay attached to the outer wall of the cable core 9 is more uniform, and the mica tape 51 wrapped outside the fire clay can be pressed, the gas inside the mica tape 51 is extruded, so that the mica tape 51 and the fire clay layer are better attached, and the phenomenon that the mica tape 51 is loose is avoided.

When the mica tape 51 is over-loose when winding the cable core 9, the two half gears 33 are driven to rotate under the action of the torsion springs 35, the two adjusting rods 32 are driven to rotate by the two half gears 33, and the mica tape 51 is in the appropriate tension range through the setting of the torsion springs 35, which is convenient and fast.

[0040] The adjusting ring 4 can limit the rotation angle of the synchronous shaft 52, and ensure that the synchronous shaft 52 is more stable during rotation. The end of the adjusting rod 32 connected to the inner wall of the adjusting ring 4 moves synchronously, the half gears 33 arranged at the other ends of the adjusting rods 32 rotate simultaneously, one end of the torsion springs 35 arranged on both sides of the half gears 33 rotates to store force, and the initial state of the torsion springs 35 is the force storage state. When the mica tape 51 is over-loose when winding the cable core 9, the two half gears 33 are driven to rotate under the action of the torsion springs 35, the two adjusting rods 32 are driven to rotate by the two half gears 33, and the mica tape 51 is in the appropriate tension range through the setting of the torsion springs 35, which is convenient and fast.

[0041] The adjusting groove 36 is arranged at the end of the mounting shaft 3 away from the rotating seat 21, the synchronous shaft 52 is connected in the adjusting groove 36, the winding roller 5 is movably sleeved on the outer wall of the synchronous shaft 52, and the synchronous shaft 52 is connected with the blocking piece 57.

[0042] The blocking piece 57 can limit the winding roller 5, so that the winding roller 5 does not shake during work.

[0043] The rotating ball sleeve 53 is fixedly sleeved on the outer wall of the synchronous shaft 52 close to the adjusting groove 36, the rotating ball sleeve 53 is arranged in the middle of the adjusting groove 36, the support shaft 54 is fixedly connected to both ends of the rotating ball sleeve 53, and the support shaft 54 rotates and penetrates the inner wall of the adjusting groove 36.

[0044] The winding roller 5 drives the synchronous shaft 52 to rotate, the synchronous shaft 52 rotates around the supporting shaft 54 as the axis, and the rotating ball sleeve 53 plays a supporting role. In the rotating process of the synchronous shaft 52, the adjusting ring 4 slides along the outer wall of the synchronous shaft 52 towards the winding roller 5, and the elastic limiting sleeve 41 is arranged to increase the stability of the synchronous shaft 52 in the rotating process. The adjusting ring 4 can limit the rotation angle of the synchronous shaft 52, and the synchronous shaft 52 is more stable in the rotating process.

[0045] Specifically, the diameter of the one end of the adjusting ring 4 away from the rotating seat 21 is smaller than the diameter of the one end of the adjusting ring 4 close to the rotating seat 21, and the supporting shaft 54 is in contact with the inner wall of the adjusting ring 4.

[0046] The adjusting ring 4 slides along the outer wall of the synchronous shaft 52 towards the winding roller 5, and the adjusting ring 4 can limit the rotation angle of the synchronous shaft 52, and the synchronous shaft 52 is more stable in the rotating process. The adjusting rod 32 drives the adjusting ring 4 to move away from the winding roller 5 when rotating, and the adjusting ring 4 can make the synchronous shaft 52 rotate along the supporting shaft 54 during movement, and the one end of the synchronous shaft 52 close to the winding roller 5 moves away from the cable core 9.

[0047] The inner wall of the adjusting ring 4 is fixedly connected with the elastic limiting sleeve 41, and the end of the supporting shaft 54 is slidingly connected in the elastic limiting sleeve 41.

[0050] When the tension of the mica tape 51 is too large and exceeds the adjusting range of the torsion spring 35, the winding roller 5 will rotate along the outer wall of the rotating ball sleeve 53 under the pulling of the mica tape 51 to adjust, further ensuring that the mica tape 51 will not be too tight during winding. The friction plate 55 arranged on the outer wall of the winding roller 5 plays a supporting role on the inner wall of the winding roller 5, so that the winding roller 5 can rotate synchronously with the synchronous shaft 52. The yielding spring 56 makes the friction plate 55 in a tightly contacted state with the inner wall of the winding roller 5, increasing the stability of the winding roller 5 in the rotating process. The arrangement of the baffle 57 can limit the winding roller 5, avoiding the phenomenon of shaking of the winding roller 5 during work.

[0051] Working principle: when the cable core 9 is wrapped, the cable core 9 will pass through the through hole in the middle of the rotating seat 21 and move to the inside of the through hole, and in the process of moving the cable core 9, the output end of the driving motor 11 drives the driving gear 12 to rotate, and the driving gear 12 drives the transmission gear 2 to rotate in the rotating process, and the transmission gear 2 drives the rotating seat 21 to rotate synchronously.

[0052] The rotating seat 21 drives the two sides of the mounting shaft 3 to rotate, and the mounting shaft 3 drives the telescopic push rod 6 to rotate at the same time, and the telescopic end of the telescopic push rod 6 drives the arc-shaped plate 61 provided at the end to move circumferentially along the outer wall of the cable core 9, and the arc-shaped plate 61 supports and limits the cable core 9, so that the cable core 9 can pass through the through hole more stably and accurately, and in the process of rotating the arc-shaped plate 61, the arc-shaped plate 61 can rotate along the outer wall of the cable core 9 and can extrude the outer wall of the cable core 9, so that the fireclay attached to the outer wall of the cable core 9 is more uniform, and the mica tape 51 wrapped by the fireclay can be pressed, so that the gas in the mica tape 51 is extruded, and the mica tape 51 and the fireclay layer are better attached, avoiding the phenomenon that the mica tape 51 is loose.

[0053] The mounting shaft 3 drives the synchronous shaft 52 to rotate synchronously in the process of rotating, and the synchronous shaft 52 drives the winding roller 5 sleeved on the outer wall to rotate when rotating, and the winding roller 5 can wind the mica tape 51 wound on the outer wall on the outer wall of the cable core 9, when the mica tape 51 is too tight, the mica tape 51 will pull the winding roller 5 to move towards the cable core 9, so that the mica tape 51 is in a moderate state in time, avoiding the breakage of the mica tape 51 due to excessive tension, and in this process, the winding roller 5 drives the synchronous shaft 52 to rotate, and the synchronous shaft 52 rotates around the support shaft 54, and the rotating ball sleeve 53 plays a supporting role, and in the process of rotating the synchronous shaft 52, the adjusting ring 4 will slide along the outer wall of the synchronous shaft 52 towards the winding roller 5, and the elastic limiting sleeve 41 can increase the stability of the synchronous shaft 52 in the process of rotating, and the adjusting ring 4 can limit the rotation angle of the synchronous shaft 52 to ensure that the synchronous shaft 52 rotates more stably, and the end of the adjusting rod 32 connected to the inner wall of the adjusting ring 4 moves synchronously when the adjusting ring 4 moves, and the half gear 33 at the other end of the adjusting rod 32 rotates at the same time, and one end of the torsion spring 35 provided on both sides of the half gear 33 rotates to store energy.

[0054] The torsion spring 35 is in the initial state of storing force, when the mica tape 51 appears loose phenomenon in winding the cable core 9, the torsion spring 35 drives the two half gears 33 to rotate, the two half gears 33 drive the two adjusting rods 32 to rotate, the adjusting rod 32 drives the adjusting ring 4 to move away from the winding roller 5 when rotating, the adjusting ring 4 can make the synchronous shaft 52 rotate along the support shaft 54 direction in the process of moving, the end of the synchronous shaft 52 close to the winding roller 5 moves away from the cable core 9, so as to achieve the action of tensioning the mica tape 51, through the setting of the torsion spring 35, the mica tape 51 can be in the appropriate tension range, convenient and fast.

[0055] When the tension of the mica tape 51 is too large, beyond the adjustment range of the torsion spring 35, the winding roller 5 will rotate along the outer wall of the rotating ball sleeve 53 under the pulling of the mica tape 51 to adjust, further ensure that the mica tape 51 will not appear too tight in the winding process, the friction plate 55 arranged on the outer wall of the winding roller 5 supports the inner wall of the winding roller 5, so that the winding roller 5 can rotate synchronously with the synchronous shaft 52, the displacement spring 56 makes the friction plate 55 and the inner wall of the winding roller 5 in the state of abutting tightly, increase the stability of the winding roller 5 in the rotating process, the setting of the baffle 57 can limit the position of the winding roller 5, avoid the phenomenon of shaking of the winding roller 5 in the working process.
