DETAILED DESCRIPTION

[0009] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0010] Reference Figures 1 to 4 An embodiment provided by the present application: an insulating cable production equipment, comprising a base 1 which plays a stable foundation supporting role for the whole insulating cable production equipment and provides a flat and reliable installation platform for each component, and a rotating ring 4 which can rotate smoothly and provides a solid installation carrier for components such as the fixed ring 8 and drives them to rotate coordinately. The rotating ring 4 is fixedly connected with a plurality of fixed rings 8 which internally install components such as telescopic rods 11, springs I 12 and clamping plates 13. These fixed rings 8 provide a closed and stable installation space for internal components, and drive each component to keep a synchronous movement state during rotation. The proximal end of each fixed ring 8 is fixedly connected with a fixed plate 9 which connects the fixed ring 8 and the connecting disc 10. The fixed plate 9 realizes the functions of fixing and supporting through rigid connection, and ensures that the fixed ring 8 and the connecting disc 10 always keep synchronous movement during rotation. The proximal end of each fixed plate 9 is fixedly connected with a connecting disc 10 which connects a plurality of fixed plates 9. The connecting disc 10 not only forms a whole structure with the dispersed fixed plates 9, but also provides a smooth sliding channel and stable support for the sliding rod 25, ensuring that the sliding rod 25 does not shake during movement. The inner part of the fixed ring 8 is fixedly connected with the telescopic rods 11 which play the role of accurate guiding and strict limiting for the movement of the clamping plates 13, so as to effectively limit the movement direction of the clamping plates 13 and prevent them from deviating when being stressed. The outer part of the telescopic rods 11 is sleeved with the springs 12 which can realize quick resetting through their own elastic potential when the device is closed and rotated, so that the clamping plates 13 can quickly return to the initial position, greatly facilitating the next use of the device. One end of the spring 12 is fixedly connected to the inner part of the fixed ring 8, and the other end of the plurality of springs 12 is fixedly connected to the far ends of the clamping plates 13 which are used in cooperation with the fixed clamping plates 16. These clamping plates 13 can firmly clamp and fix the cable material and can flexibly adapt to the fixing needs of cables of different lengths. The proximal ends of the plurality of telescopic rods 11 are fixedly connected with the clamping plates 13, and the proximal ends of the plurality of clamping plates 13 are fixedly connected with the two soft iron wires 14 which are tightly wound on the limiting discs 15 when the fixed ring 8 rotates. The soft iron wires 14 can smoothly pull the clamping plates 13 to move through the change of their own length, and always remain straight after the clamping plates 13 fix the cable, so as to ensure the stable transmission of clamping force. The proximal ends of the plurality of soft iron wires 14 are fixedly connected with the limiting discs 15 for winding the soft iron wires 14. The limiting discs 15 will rotate when the soft iron wires 14 are straightened, thereby driving the sliding rods 25 to synchronously rotate, and playing the role of accurate limiting and stable supporting for the sliding rods 25. The inner part of the fixed ring 8 is fixedly connected with the fixed clamping plates 16 which are fixed in the inner part thereof. The fixed clamping plates 16 cooperate with the clamping plates 13 to reliably limit and fix the cable material from both sides, so as to ensure that the cable does not displace during the processing. The left end of the rotating ring 4 is fixedly connected with the gear ring 5 which is engaged with the gear 7. The gear ring 5 can efficiently transmit the rotary power of the gear 7 to the rotating ring 4, so that the rotating ring 4 obtains continuous and stable rotary power. The top end of the base 1 is fixedly connected with the motor 6 which provides sufficient driving power for the operation of the gear 7. As the core power source for the operation of the device, the motor 6 can ensure that the gear 7 maintains a stable rotating speed. The driving end of the motor 6 is fixedly connected with the gear 7 which rotates at a constant speed under the driving of the motor 6. The gear 7 transmits power through the close engagement with the gear ring 5, so as to drive the gear ring 5 to synchronously rotate. The gear 7 and the gear ring 5 always maintain a stable engagement state. Referring to Figure 3 and Figure 5The outer part of the rotating ring 4 is rotationally connected with a limiting ring 3 which strictly limits the rotating range of the rotating ring 4, which can effectively prevent the radial deviation of the rotating ring 4 during rotation, and ensure the stability of the equipment operation. The bottom end of the rotating ring 4 is fixedly connected with a support block 2 which plays a stable supporting role for the rotating ring 4, which can assist in dispersing the stress during the rotating process of the rotating ring 4, and maintain the balance state of the rotating ring 4. The right end of the rotating ring 4 is provided with a sliding groove 20 which provides sufficient sliding space for the limiting column 21, and the sliding groove 20 allows the limiting column 21 to slide flexibly according to the actual needs, so as to adapt to different working scenes. The inner part of the sliding groove 20 is slidably connected with two limiting columns 21 which slide smoothly in the sliding groove 20, which plays a precise guiding and effective limiting role for the movement of the connecting plate 19, and ensures that the connecting plate 19 maintains a stable state during movement. The right end of the two limiting columns 21 is fixedly connected with the connecting plate 19 which connects the limiting column 21 and the limiting circular ring 18, and the connecting plate 19 can uniformly transmit the supporting force of the limiting column 21 to the limiting circular ring 18, so as to ensure that the position of the limiting circular ring 18 does not change during work. The proximal end of the two connecting plates 19 is fixedly connected with the limiting circular ring 18 which precisely guides the combined cable, which can effectively limit the movement direction of the cable, and at the same time plays a reliable limiting role for the cable, preventing the cable from being scattered during processing. The bottom end of the limiting circular ring 18 is fixedly connected with the support plate 17 which supports the limiting circular ring 18, which provides a solid installation basis for the limiting circular ring 18, and ensures that it maintains a stable position when bearing the force of the cable. The left end of the connecting plate 19 is fixedly connected with the connecting block 22 which connects the connecting plate 19 and the fixed circular ring 23, which can smoothly transmit the force of the connecting plate 19 to the fixed circular ring 23, and ensure that the fixed circular ring 23 always maintains a stable position state during equipment operation. The left end of the two connecting blocks 22 is fixedly connected with the fixed circular ring 23 which strictly limits the movement range of the top plate 31, which can effectively prevent the damage of parts caused by excessive movement of the top plate 31. Referring to Figure 6 and Figure 7 The top end of the base 1 is fixedly connected with the limiting long plate 24 which is internally provided with a limiting groove 30, which provides a preset path for the sliding of the sliding block 29, and at the same time plays a stable supporting role for the related parts, ensuring the rigidity of the overall structure. The inner part of the limiting long plate 24 is slidably connected with the sliding rod 25 which drives the sliding block 29 to rotate synchronously during rotation, which can drive the top plate 31 to move correspondingly during the movement process, and at the same time smoothly slide in the inner part of the connecting disc 10 and the limiting disc 15, realizing the precise transmission of movement. The outer part of the sliding rod 25 is movably connected to the inner part of the connecting disc 10, and the outer part is also movably connected to the inner part of the limiting disc 15, which ensures the stability of the sliding process through double limiting and supporting. The right end of the limiting long plate 24 is fixedly connected with a limiting sleeve 26 which plays a precise limiting role in the movement of the sliding rod 25, so as to ensure that the sliding rod 25 always moves in the preset direction and avoids deviation. The outside of the sliding rod 25 is slidingly connected to the inside of the limiting sleeve 26, and the outside of the fixed circular block 27 is also slidingly connected to the inside of the limiting sleeve 26, forming a multiple limiting structure. The outside of the sliding rod 25 is rotatably connected with the fixed circular block 27 which effectively limits the rotation of the sliding rod 25, and the fixed circular block 27 can assist the sliding rod 25 to maintain a stable state during movement and reduce shaking. The outside of the sliding rod 25 is slidingly connected with a spring 28 which realizes the reset function by its own elastic force, and the spring 28 can assist the sliding rod 25 to quickly reset after movement, ensuring that the sliding rod 25 can perform stable reciprocating motion. One end of the spring 28 is fixedly connected to the left end of the fixed circular block 27, and the other end of the spring 28 is fixedly connected to the left end of the inner wall of the limiting sleeve 26, forming a stable elastic reset structure. The outside of the sliding rod 25 is fixedly connected with a sliding block 29 which rotates synchronously with the sliding rod 25, and the sliding block 29 slides smoothly in the groove in the limiting groove 30, thereby driving the sliding rod 25 to move forward. The inside of the limiting long plate 24 is provided with a limiting groove 30 which provides a preset sliding path for the sliding block 29, and the limiting groove 30 controls the movement trajectory of the sliding rod 25 through the internal spiral and straight grooves, ensuring that the sliding rod 25 can be precisely reset. The right end of the sliding rod 25 is fixedly connected with a top plate 31 which moves under the driving of the sliding rod 25, and the top plate 31 can precisely top the nodes intersected when the cable is twisted, making the cable combination more stable and compact. The limiting groove 30 is designed in a spiral shape and connected in a straight line at the top, and through this special structure design, the sliding rod 25 can be accurately reset after one rotation, ensuring the cyclic working performance of the equipment.

[0014] Through the clamping and fixing of the material by the clamping plate 13, the soft iron wire 14 is straightened, thereby driving the rotation of the limiting disc 15, through the rotation of the limiting disc 15 to drive the rotation of the sliding rod 25, through the rotation of the sliding rod 25 to drive the rotation of the sliding block 29, through the sliding of the sliding block 29 in the groove inside the limiting groove 30 to move the sliding rod 25 forward, through the groove inside the limiting long plate 24, the sliding rod 25 is reset by the limiting of the fixed circular block 27 and the elastic force of the spring two 28, through the movement of the sliding rod 25 to drive the movement of the top plate 31, through the movement of the top plate 31 to top the nodes intersected when the cable is twisted, so that the cable combination is more stable and compact.

[0015] The movement of the top plate 31 is limited under the action of the fixed circular ring 23, the combined cable is guided and limited by the limiting circular ring 18, the sliding rod 25 slides inside the connecting disc 10 and the limiting disc 15, the limiting disc 15 and the connecting disc 10 limit and support the sliding rod 25 to move more stably, prevent the situation of falling off and warping, and after the cable processing is completed, through the limiting of the telescopic rod 11 and the elasticity of the spring one 12, when the device is closed, the spring one 12 is reset by the elastic force, so that the clamping plate 13 is reset, which is convenient for the next use of the device.
