Description

Technical Field

[0001] The invention relates to the technical field of cables, in particular to a high-strength silicone rubber soft cable. Background Art

[0002] Silicone rubber cable is a cable made of silicone rubber as insulation material. It has special high and low temperature resistance and can be used in a wide temperature range. The cable has excellent flexibility, electrical insulation, environmental stress cracking resistance, weather resistance and UV resistance. It can be used outdoors, in humid environments, at high temperatures, at low temperatures and other harsh conditions. In addition, the cable has good UV and ozone resistance and will not age due to long-term exposure to strong UV and ozone.

There are four insulating cores in total, and three of the four insulating cores are composed of a single bundle of twisted conductors extruded with a single insulating layer, and another of the four insulating cores is composed of multiple bundles of twisted conductors extruded with insulating layers twisted into a cable and then wrapped with a tape layer. The four insulating cores are wrapped with a tape layer. The cable has the characteristics of wear resistance, softness, flame retardancy, high and low temperature resistance, acid and alkali resistance, oil and water resistance, tear resistance, and good and stable signal transmission function, and has broad market prospects and practicality.

[0004] In the prior art including the above-mentioned patents, the production steps of silicone rubber cables and ordinary cables are slightly different. Ordinary cables are mostly made by melting the insulation layer raw materials through an extruder and covering the insulation layer on the conductor, and then solidifying the insulation layer through cooling. In the production process of silicone rubber cables, the insulation layer needs to be vulcanized at high temperature after the insulation layer is attached to further improve the performance of the insulation layer. The conductor is wound on a reel during storage and transportation, and the conductor has a certain curvature. Moreover, in the process of moving the conductor from the extruder to the vulcanization tube, the insulation layer of the conductor is relatively soft and cannot provide sufficient support for the conductor, causing the conductor to move relative to the extruder, resulting in the conductor not being in the center of the extruder channel, resulting in uneven thickness of the insulation layer attached to the conductor, affecting the quality of the conductor.

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-8 As shown, a high-strength silicone rubber flexible cable includes an extruder 2 and a vulcanizing tube 3, and also includes a connecting shell 1 connecting the extruder 2 and the vulcanizing tube 3, the connecting shell 1 is provided with first guide grooves 12 symmetrically distributed up and down, and a plurality of clamping units 11 are movably provided on the two first guide grooves 12, and the corresponding clamping units 11 on the two first guide grooves 12 form a group, and the clamping unit 11 includes a mounting shell 111, a blocking piece 112 symmetrically and movably mounted on the mounting shell 111 and used to block the insulating layer material, and a supporting mechanism 113 located between the two blocking pieces 112, the supporting mechanism 113 includes a movable belt 114 fixedly mounted on the mounting shell 111 at both ends and a push rod 115 symmetrically and slidably mounted on the mounting shell 111 and used to support the movable belt 114, and the two push rods 115 move relative to the mounting shell 111 to enable the movable belt 114 to clamp the wire or extrude the insulating layer material to shape the insulating layer.

[0030] Specifically, the first guide groove 12 includes two parallel horizontal portions 123 and a vertical portion 125 and an inclined portion 124 connecting the two horizontal portions 123. A guide block 122 adapted to the horizontal portion 123 and the vertical portion 125 of the first guide groove 12 is provided on the mounting shell 111. A notch adapted to the inclined portion 124 is provided on the guide block 122. A conveyor belt 121 adapted to the first guide groove 12 is movably provided in the connecting shell 1. The guide block 122 is rotatably installed on the conveyor belt 121. A spring is provided between the blocking piece 112 and the mounting shell 111. The blocking piece 112 is provided with a groove adapted to the wire.

[0031] In the above technical scheme, when working, the wire is sent to the extruder 2, the extruder 2 melts the silicone rubber raw material and attaches it to the wire to form an insulating layer of the wire, and the wire moves with the insulating layer, passes through the connecting shell 1 and enters the vulcanizing tube 3, and the vulcanizing tube 3 vulcanizes the insulating layer of the wire to improve the performance of the insulating layer. At this time, the conveyor belt 121 carries the clamping unit 11 through the guide block 122 and moves along the inclined portion 124 of the guide groove to the horizontal portion 123 away from the wire. The conveyor belt 121 continues to move, and the clamping unit 11 enters the vertical portion 125 and moves along the vertical portion 125. The clamping unit 11 moves closer to the wire, and a pair of clamping units 11 in the upper and lower first guide grooves 12 gradually move closer, and the barrier sheet 112 is embedded in the insulating layer of the wire and stuck on the wire. The two mounting shells 111 are close together, and the mounting shell 111 and the barrier sheet 112 are combined to form a sealed cavity. At this time, the push The rod 115 moves and pushes the movable belt 114 to deform. The two pairs of push rods 115 gradually lean against the wire, clamp the wire, provide support for the wire, keep the wire in the middle of the channel of the extruder 2, so that the insulation layer extruded by the extruder 2 can be evenly distributed around the wire, and the conveyor belt 121 continues to move. The clamping unit 11 moves synchronously with the wire along the horizontal portion 123 of the first guide groove 12 close to the wire, and gradually moves to the connection between the inclined portion 124 of the horizontal portion 123. At this time, the push rod 115 moves away from the wire and gradually loosens the wire. The push rod 115 pulls the movable belt 114 to move, so that the movable belt 114 gradually returns to a semicircular shape, squeezes the insulation layer on the wire, shapes the insulation layer of the wire, and makes the insulation layer on the wire tend to be a perfect circle. The next pair of clamping units 11 clamps the wire to keep it in the middle of the channel of the extruder 2.

[0032] As a further embodiment of the present invention, a plurality of sealing strips 118 are provided on the movable belt 114 , and the sealing strips 118 are slidably mounted on the mounting shell 111 .

[0033] Specifically, a spring is provided between the sealing strip 118 and the mounting shell 111 , and the plurality of sealing strips 118 are divided into two groups to seal the gap between the movable belt 114 and the mounting shell 111 .

[0034] Furthermore, in the process of the push rod 115 pushing the movable belt 114 to move, the movable belt 114 drives the sealing strip 118 to move, and the multiple sealing strips 118 cooperate to seal the gap between the movable belt 114 and the mounting shell 111 to prevent the insulating layer on the wire from entering the gap between the movable belt 114 and the mounting shell 111 when being squeezed, and the sealing strip 118 restricts the movable belt 114 from both sides of the movable belt 114 to prevent the movable belt 114 from being damaged due to unbalanced force on both sides when squeezing the insulating layer.

[0035] As another embodiment further provided by the present invention, a shaping mechanism 13 for shaping the insulating layer is disposed in the mounting shell 111 , and the supporting mechanism 113 and the shaping mechanism 13 are sequentially distributed along the moving direction of the wire.

[0036] Specifically, in the process of the two clamping units 11 approaching each other, the push rod 115 moves and gradually presses against the conductor, the movable belt 114 squeezes the insulation layer, and part of the remaining insulation layer can be moved by the support mechanism 113 to the shaping mechanism 13, so as to avoid the excess insulation layer material from being continuously squeezed between the two movable belts 114 on a pair of clamping units 11, thereby extending the service life of the movable belt 114; when the next pair of clamping units 11 takes over the clamping work, the push rod 115 moves to make the movable belt 114 return to a semicircular shape, and at this time the shaping mechanism 13 squeezes the insulation layer of the conductor, so that the squeezed remaining insulation layer returns to between the movable belts 114, and the movable belt 114 shapes the insulation layer of the clamped part, and after the shaping is completed, the pair of clamping units 11 gradually separate, and the insulation layer parts clamped by the shaping mechanism 13 and the support mechanism 113 enter the vulcanizing tube 3 in turn, and the narrow mouth of the vulcanizing tube 3 can squeeze the two parts of the insulation layer in turn, and shape the insulation layer again, so that the materials of the two parts of the insulation layer are evenly distributed.

[0037] As another embodiment further provided by the present invention, the shaping mechanism 13 includes a plurality of clamping blocks 131 movably mounted on the mounting shell 111 , and a plurality of clamping blocks 131 in a group of clamping units 11 form a shaping cylinder.

[0038] Specifically, when the next pair of clamping units 11 takes over the clamping work, the push rod 115 moves to make the movable belt 114 return to a semicircle. At this time, the multiple clamping blocks 131 in the shaping mechanism 13 move, and the multiple clamping blocks 131 move along the radial direction of the wire, and extrude the insulation layer of the wire at multiple angles at the same time. The multiple clamping blocks 131 in a pair of clamping units 11 are brought together to form a shaping cylinder, which squeezes the insulation layer on the wire into a cylindrical shape, and returns the extruded excess insulation layer to the movable belts 114, and the movable belts 114 shape the insulation layer of the clamped part.

[0039] As another embodiment further provided by the present invention, a driving half ring 132 for driving the plurality of clamping blocks 131 to move is movably provided on the mounting shell 111 , and the two driving half rings 132 form a driving ring and rotate at a fixed position.

[0040] Specifically, the clamping block 131 is provided with a tenon block 133 extending into the mounting shell 111, the mounting shell 111 is provided with a slide groove adapted to the tenon block 133, the driving ring composed of two driving half rings 132 is provided with a first plane thread, and the tenon block 133 is provided with a guide groove adapted to the first plane thread.

[0041] Furthermore, in the process of the two clamping units 11 being pressed against each other and moving along the horizontal portion 123 of the first guide groove 12 close to the conductor, the driving ring rotates, and the first planar thread on the driving ring moves along the slide groove on the tenon block 133, pushing the tenon block 133 and the clamping block 131 closer to the conductor, and multiple clamping blocks 131 are tightly attached together to form a shaping cylinder, which squeezes the insulating layer on the conductor into a cylindrical shape. After the shaping work is completed, the driving ring rotates in the opposite direction, and the two driving half rings 132 retract into their respective corresponding mounting shells 111, and the clamping block 131 moves away from the conductor to wait for the next work.

[0042] As another embodiment further provided by the present invention, a first slider 128 for driving the driving half ring 132 to move is disposed on the mounting shell 111 , and a second guide groove 126 adapted to the first slider 128 is disposed inside the connecting shell 1 .

[0043] Specifically, a spring is provided between the driving half ring 132 and the mounting shell 111 , a slope is provided at the end of the second guide groove 126 , a spring is provided between the first slider 128 and the mounting shell 111 , and a first cable 134 is provided between the first slider 128 and the driving half ring 132 .

[0044] Furthermore, when the mounting shell 111 moves to the position where the first slider 128 is opposite to the second guide groove 126, the first slider 128 moves under the action of the spring and extends into the second guide groove 126. At this time, the first slider 128 pulls the driving half ring 132 to rotate through the first cable 134, and the two driving half rings 132 rotate to move the clamping block 131, while the spring between the driving half ring 132 and the mounting shell 111 accumulates elastic potential energy; the mounting shell 111 continues to move, the first slider 128 moves to the end of the second guide groove 126, and moves to the outside of the second guide groove 126 along the slope of the second guide groove 126, and the first slider 128 retracts into the mounting shell 111. At this time, the spring between the driving half ring 132 and the mounting shell 111 releases the accumulated elastic potential energy, driving the driving half ring 132 to move in the opposite direction, and driving the clamping block 131 to move.

[0045] As another embodiment further provided by the present invention, a second slider 129 for driving the push rod 115 to move is disposed on the mounting shell 111 , and a third guide groove 127 adapted to the second slider 129 is disposed on the connecting shell 1 .

[0046] Specifically, a driving disk 117 for driving the two push rods 115 to move is provided on the mounting shell 111, a second planar thread is provided on the driving disk 117, a sliding groove adapted to the second planar thread is provided on the push rod 115, a torsion spring is provided between the driving disk 117 and the mounting shell 111, a second cable 135 is provided between the second slider 129 and the driving disk 117, a spring is provided between the second slider 129 and the mounting shell 111, a slope is provided at the end of the third guide groove 127, a square connecting rod 116 is provided on one of the push rods 115, and a through hole adapted to the connecting rod 116 is provided on the other push rod 115, and the two push rods 115 are restricted by the connecting rod 116 to always remain parallel.

[0047] Furthermore, in the process of the two clamping units 11 being pressed against each other and moving along the horizontal portion 123 of the first guide groove 12 close to the wire, the mounting shell 111 moves with the second slider 129 thereon to a position opposite to the third guide groove 127. The second slider 129 extends into the third guide groove 127 under the action of the spring. The second slider 129 drives the driving disk 117 to rotate through the second cable 135. The second planar thread on the driving disk 117 moves along the slide groove on the push rod 115, thereby pushing the two push rods 115 closer together. The push rod 115 pushes the movable belt 114 to deform, squeezes the insulating layer on the wire and clamps it on the wire. The two supporting mechanisms 113 on a pair of clamping units 11 cooperate to limit the wire and provide support force for the wire, so that the wire is in the middle of the channel of the extruder 2.

[0048] As another embodiment further provided by the present invention, the width of the first sliding block 128 and the width of the second sliding block 129 are both greater than the width of the first guide groove 12, and the second guide groove 126 and the third guide groove 127 are alternately distributed.

[0049] Specifically, the wider first slider 128 and the second slider 129 can prevent them from falling into the first guide groove 12 when passing through the first guide groove 12, and the staggered distribution of the second guide groove 126 and the third guide groove 127 can allow the clamping unit 11 to drive the first slider 128 and the second slider 129 to move at the appropriate position.

[0050] As another embodiment further provided by the present invention, a sealing strip 118 on one side of the movable belt 114 is provided with a protruding piece 119 extending to the clamping block 131 .

[0051] Specifically, during operation, the conductor is sent to the extruder 2, which melts the silicone rubber raw material and attaches it to the conductor to form an insulating layer of the conductor. The conductor moves with the insulating layer, passes through the connecting shell 1 and enters the vulcanizing tube 3, and the vulcanizing tube 3 vulcanizes the insulating layer of the conductor to improve the performance of the insulating layer. At this time, the conveyor belt 121 carries the clamping unit 11 through the guide block 122 and moves along the inclined portion 124 of the guide groove toward the horizontal portion 123 away from the conductor. The conveyor belt 121 continues to move, and the clamping unit 11 enters the vertical portion 125 and moves along the vertical portion 125. The clamping unit 11 moves closer to the conductor, and a pair of clamping units 11 in the upper and lower first guide grooves 12 gradually move closer. The barrier sheet 112 is embedded in the insulating layer of the conductor and stuck on the conductor, and the two mounting shells 111 are brought together, and the mounting shells 111 and the barrier sheet 112 are combined to form a sealed cavity.

[0052] The conveyor belt 121 continues to move, driving the clamping unit 11 to move synchronously with the wire along the horizontal portion 123 of the first guide groove 12 close to the wire. The mounting shell 111 moves the second slider 129 thereon to a position facing the third guide groove 127. The second slider 129 extends into the third guide groove 127 under the action of the spring. The second slider 129 drives the driving disk 117 to rotate through the second cable 135. The second plane thread on the driving disk 117 moves along the slide groove on the push rod 115, thereby pushing the two push rods 115 closer together. The push rod 115 pushes the movable belt 114 to deform, squeezes the insulating layer on the wire and clamps it on the wire. The two supporting mechanisms 113 on the pair of clamping units 11 Cooperate to limit the wire and provide support force for the wire, so that the wire is in the middle of the channel of the extruder 2, so that the insulation layer extruded by the extruder 2 can be evenly distributed around the wire, and the movable belt 114 squeezes the insulation layer on the wire, and the excess insulation layer material is squeezed between the shaping mechanism 13, and the sealing strip 118 moves with the movable belt 114, and multiple sealing strips 118 cooperate to seal the gap between the movable belt 114 and the mounting shell 111 to prevent the insulation layer on the wire from entering the gap between the movable belt 114 and the mounting shell 111 when squeezed, and the sealing strip 118 limits the movable belt 114 from both sides of the movable belt 114 to prevent the movable belt 114 from being damaged due to unbalanced force on both sides when squeezing the insulation layer.

[0053] The conveyor belt 121 continues to move, and the pair of clamping units 11 gradually approaches the vulcanizing tube 3. At this time, the next pair of clamping units 11 takes over the clamping work, and the second slider 129 on the mounting shell 111 moves along the slope at the end of the third guide groove 127 to the outside of the third guide groove 127. The second cable 135 is relaxed, and the driving disk 117 rotates in the opposite direction under the action of the torsion spring, pushing the push rod 115 to move away from the wire, gradually loosening the wire, and the spring between the sealing strip 118 and the mounting shell 111 pushes the sealing strip 118 and the movable belt 114 to move, so that the movable belt 114 gradually returns to a semicircular shape and squeezes the insulating layer on the wire. At this time, the first slider 128 is opposite to the second guide groove 126. The first slider 128 moves under the action of the spring and extends to the second guide groove 126. At this time, the first slider 128 drives the half ring 132 to rotate through the first cable 134, and the driving ring composed of the two driving half rings 132 rotates, and the first plane thread on the driving ring moves along the slide groove on the tenon block 133, pushing the tenon block 133 and the clamping block 131 to move closer to the wire, and multiple clamping blocks 131 are tightly attached together to form a shaping cylinder, which squeezes the insulating layer on the wire into a cylindrical shape and squeezes the excess insulating layer material back to the bottom of the movable belt 114, and the clamping block 131 pushes the protrusion 119 on the sealing strip 118, so that the sealing strip 118 pushes the movable belt 114 to move, so that the shape of the movable belt 114 is more semicircular, and the movable belts 114 of the two clamping units 11 cooperate to shape the insulating layer of the wire, so that the insulating layer on the wire tends to be a perfect circle.

[0054] The conveyor belt 121 continues to move, the first slider 128 moves to the end of the second guide groove 126, and moves to the outside of the second guide groove 126 along the slope of the second guide groove 126, and the first slider 128 retracts into the mounting shell 111. At this time, the spring between the driving half ring 132 and the mounting shell 111 releases the stored elastic potential energy, driving the driving half ring 132 to move in the opposite direction, driving the clamping block 131 to move away from the wire, and the guide block 122 on the mounting shell 111 enters the inclined portion 124 of the first guide groove 12. The pair of clamping units 11 gradually separates, and the wire enters the vulcanizing tube 3. The insulating layer parts clamped by the shaping mechanism 13 and the supporting mechanism 113 enter the vulcanizing tube 3 in turn. The narrow mouth of the vulcanizing tube 3 can squeeze the two parts of the insulating layer in turn, and shape the insulating layer again, so that the materials of the two parts of the insulating layer are evenly distributed. Then the vulcanizing tube 3 vulcanizes the insulating layer on the wire to improve the performance of the insulating layer of the wire.

[0055] Furthermore, in the above embodiment, the corresponding sealing strips 118 on both sides of the movable belt 114 can be connected together to further improve the synchronization of the sealing strips 118 .

[0056] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
