Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wire storage equipment, in particular to a coaxial cable physical foaming insulation wire storage device and its use method. BACKGROUND

[0002] The coaxial cable physical foaming insulation wire is an insulation structure with uniform and small closed pores formed in the polyethylene insulation material by physical methods (gas injection), which is the core component of the coaxial cable and is located between the inner conductor and the outer conductor. The inner conductor structure is a solid copper wire or aluminum wire, which provides a current-carrying channel. However, the insulation wire storage device is a key auxiliary equipment in the production process of the insulation core wire, and its core function is to temporarily store the insulation wire conductor or finished insulation wire. By dynamically adjusting the storage amount and release speed of the cable, the production cycle difference between the front and rear processes (such as extruders, take-up machines, and pay-off racks) is balanced. In the prior art, the core executive components of the wire storage device are the wire storage rack, the wire guide wheel, the tension disc, and the take-up gantry. The arrangement mode directly determines the wire storage path, the tension effect, and the guiding stability of the insulation wire. The currently used tension disc arrangement form is mainly parallel and opposite arrangement. In the parallel and opposite arrangement, two or more tension discs are arranged in parallel along the same axis, so that the insulation wire passes through the tension discs in a straight or approximately straight path. Due to the linear wire storage path formed by the parallel and opposite arrangement, the tension fluctuation caused by the sudden change of the speed of the front and rear processes will be directly transmitted to the insulation wire body, resulting in stretching and deformation of the insulation layer when the tension is too large, and the cable is loose and accumulated when the tension is too small, which affects the product quality and storage efficiency of the insulation wire.

[0020] A method for using a coaxial cable physical foamed insulation wire storage device, comprising the following steps:

[0021] S1, first, the height and angle of the blocking cone column at the top end of the support are adjusted by the stretching assembly, so that the outside of the blocking cone column maintains a suitable position with the tensioning disc and the twisting disc, and a passive limiting channel is formed around the outer periphery of the tensioning disc and the twisting disc as the blocking cone column is adjusted, then the inclination angle is dynamically adjusted according to the wire body feeding posture and specification characteristics, a lateral component along the tangent direction of the wheel surface is generated, the wire body is continuously guided to the center of the wheel surface, the wire body is guided to move along the outer periphery of the tensioning disc and the twisting disc, and the deviation tendency is fundamentally inhibited;

[0022] S2, secondly, the wire body is sequentially penetrated from left to right through the wire storage frame, the tensioning disc, the twisting disc, the double guide roller and the guide traction wheel, so as to enable the wire body to realize continuous winding and storage operation, and then the inclination angle between the twisting disc and the tensioning disc is adjusted by the inclination adjusting assembly, so that the twisting disc and the tensioning disc maintain a Z-shaped path in an inclined staggered manner, and the wire body forms an elastic broken line contact around the outer periphery of the twisting disc and the tensioning disc.

[0023] S3, the end of the line is inserted into the double guide roller, and then the outer part of the line is surrounded by the limiting assembly, and the line is adjusted with the dynamic contact force of the twisting disc during the surrounding of the limiting assembly, the contact force is increased when the tension is small, the tension is supplemented to avoid the cable relaxation, the contact force is reduced when the tension is large, the excess tension is released to prevent the insulation layer from stretching, and the end tension is always maintained in the optimal interval, the line body is prevented from slipping at the end of the twisting disc and the double guide roller, and the stable storage of the line body is ensured;

[0024] S4, finally, after the end of the line storage, the line is locked at the guide pulley by the limiting assembly, ensuring that the line remains stable at the guide pulley, and the line is pushed by the limiting assembly during the passive process, so that the line and the clamp assembly remain in contact, and then the clamp assembly temporarily limits the outer part of the line, further improving the stability of the line at the guide pulley.

[0025] In the above technical solution, the technical effects and advantages provided by the present application are as follows:

[0026] 1, the present application through the cooperation of the tension disc and the twisting disc in the tilt adjustment frame, between the storage rack and the guide pulley, keep the up and down staggered state, so that the line body in and out of the tension disc and the twisting disc will not overlap in the same plane, then the tension disc and the twisting disc keep the inclined state under the action of the adjusting seat, so that the tension disc and the twisting disc form a Z-shaped path for the line body, the line body forms an elastic broken line contact on the outer periphery of the tension disc and the twisting disc, when the line body passes through, the path itself has a certain elastic allowance, when the speed of the previous and next processes fluctuates instantaneously, the Z-shaped path can buffer the tension change through slight deformation, rather than directly transmitting the tension to the line body, the line body will be subjected to two opposite lateral forces in the Z-shaped path, which offset each other, avoiding the torsional stress of the line body during storage, ensuring that the line body always maintains a straight posture during storage and release;

[0027] 2, the present application through the three-dimensional space distribution of the tension disc, the double guide roller and the twisting disc, the line body weight is dispersed through multiple points, the tension disc, the double guide roller and the twisting disc form two core support points through the inclined staggered tension disc, the line body is always in tension in the Z-shaped path, the weight is decomposed into tension along the axis of the line body and pressure along the surface of the tension disc and the twisting disc, avoiding the sagging of the middle section, ensuring the stability of long distance storage;

[0028] 3. The present invention, through the setting of the tensioning disc, the tensioning disc and the stop cone, makes the wheel surfaces of the tensioning disc and the tensioning disc form a natural lateral constraint angle. During the Z-shaped folding process, the insulated wire will adhere to the inclined wheel surfaces of the tensioning disc and the tensioning disc due to its own tension. The lateral component force generated by the wheel surface on the wire will automatically guide the wire to the center of the wheel surface, forming a self-centering effect, so that the movement trajectory of the wire forms a continuous and smooth zigzag line, avoiding energy loss caused by abrupt changes in trajectory, and improving the operating efficiency of the wire storage equipment.

[0029] 4. This invention uses a tilting component to adjust the angles of the tensioning disc and the twisting disc, creating a flexible tension transmission channel through the Z-shaped cable storage path. This provides a synergistic buffer against tension changes in the preceding and following processes. When a speed difference between the preceding and following processes causes tension fluctuations, the angle adjustment device can adjust the tilt angles of the tensioning disc and the twisting disc in conjunction, changing the angle of the cable path between the two discs. When the tension increases, the tilt angle is appropriately reduced to widen the angle, reducing the contact friction between the cable and the disc and alleviating some of the tension peaks. When the tension decreases, the tilt angle is increased to narrow the angle, increasing friction to compensate for the tension and prevent cable slack. This achieves graded resolution of tension fluctuations and ensures the stability of the cable storage.

[0030] 5. The present invention can form a passive limiting channel for the outer periphery of the tensioning disc and the tightening disc through the structure of the retaining cone column itself. The width and shape of the channel are adapted to the movement trajectory of the line in the inclined state of the tensioning disc and the tightening disc, so that the wheel surface of the tensioning disc and the tightening disc provides a wide fit support, so that the main force of the line is distributed in the wheel surface contact area, preventing local stress concentration and ensuring the stability of the overall line storage process.

[0031] 6. This invention achieves dynamic adaptation between the limiting component and the tightening disc, allowing the tightening disc to maintain a stable posture in accordance with the cable transmission rhythm. The contacting part of the limiting component slides synchronously with the cable movement, providing only the necessary tension fine-tuning force without interfering with the normal cable transmission. The two work together to ensure that the cable forms a stable linear transmission posture before entering the guide wheel, significantly improving the consistency of the end trajectory. In case of a sudden failure during cable storage that requires an emergency stop, the limiting component quickly switches to the locking state, rigidly locking the cable. At the same time, the end tightening disc maintains its current tilt angle, using the wheel surface friction to help fix the cable position, preventing the cable from rebounding or shifting due to inertia at the moment of locking. This ensures a neater arrangement during subsequent cable winding, more accurate measurement data during inspection, reduces rework rate in subsequent processes, and indirectly improves overall production efficiency.

[0032] 7. The present invention uses the tilting movement of the abutment rod to drive the guide column to move closer to one side of the line body along the outer perimeter of the column, thereby achieving secondary limiting of the line body on both sides of the auxiliary abutment frame. Finally, the first abutment frame and the auxiliary abutment frame work together to stably limit the line body within the optimal clamping range, strengthening the constraint stability of the auxiliary abutment frame on the outer perimeter of the line body and ensuring that the line body always maintains a stable posture under working conditions such as emergency stop.

[0064] A method for using a wire storage device for physically foamed insulated coaxial cable includes the following steps;

[0065] S1. First, the tensioning component 4 is used to adjust the height and angle of the stop cone 24 at the top of the bracket 21, so that the outside of the stop cone 24 is in a suitable position with the tensioning plate 22 and the torque plate 23. As the stop cone 24 is adjusted, a passive limiting channel is formed around the outer periphery of the tensioning plate 22 and the torque plate 23. Then, the tilt angle is dynamically adjusted according to the infeed posture and specifications of the line 12, generating a lateral component force along the tangent direction of the wheel surface, continuously guiding the line 12 to the center of the wheel surface, ensuring that the line 12 moves along the outer periphery of the tensioning plate 22 and the torque plate 23, and suppressing the tendency of deviation from the source.

[0066] S2. Next, the wire body 12 is passed through the wire storage frame 1, tensioning disc 22, twisting disc 23, double guide roller 26 and guide pull wheel 11 from left to right to enable the wire body 12 to continuously perform winding and storing operations. Then, the tilting assembly 3 is used to adjust the tilt angle between the twisting disc 23 and the tensioning disc 22 so that the twisting disc 23 and the tensioning disc 22 maintain a tilted and intersecting Z-shaped path, so that the wire body 12 forms an elastic zigzag contact on the outer periphery of the twisting disc 23 and the tensioning disc 22.

[0067] S3. Secondly, after the end of the line 12 is inserted into the double guide roller 26, the outside of the line 12 is immediately surrounded by the limiting component 5. During the period when the line 12 is surrounded by the limiting component 5, the contact force between the line 12 and the tightening disc 23 is dynamically adjusted. When the tension is too small, the contact force is increased to supplement the tension and prevent the cable from loosening. When the tension is too large, the contact force is decreased to release the excess tension and prevent the insulation layer from stretching. The two work together to keep the end tension in the optimal range, reduce the slippage of the line 12 at the end tightening disc 23 and the double guide roller 26, and ensure the stable cable storage operation of the line 12.

[0068] S4. Finally, after the end of the cable storage in the cable body 12 is completed, the limiting component 5 locks the cable body 12 at the guide wheel 11 to ensure that the cable body 12 remains sufficiently stable at the guide wheel 11. During the process of the cable body 12 being passively pushed and locked by the limiting component 5, the cable body 12 is kept in contact with the clamping component 6. Then the clamping component 6 temporarily restricts the outside of the cable body 12, further improving the stability of the cable body 12 at the guide wheel 11.

[0069] Working principle:

[0070] When using:

[0071] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, when the cable 12 is storing cable over a long distance, the first electric telescopic rod 37 drives the rack 36 to move horizontally along the guide groove 35. The rack 36 then meshes with the gear 33, thereby driving the limiting shaft 34 and the adjusting seat 31 to rotate along the top of the tilting frame 32. During the rotation of the adjusting seat 31, the bracket 21 is driven to adjust its angle along the top of the tilting frame 32. The angle change of the bracket 21 drives the tensioning disc 22 at its top to adjust its angle synchronously. At the same time, the other bracket 21, driven by the corresponding adjusting seat 31, drives the torque disc 23 to adjust its angle synchronously, realizing the synchronous linkage adjustment of the angles of the tensioning disc 22 and the torque disc 23. After the angle adjustment is completed, the tensioning disc 22 and the torque disc 23 are stably positioned in an alternating state between the cable storage frame 1 and the guide wheel 11 under the limiting action of the tilting frame 32, allowing the cable 12 to enter and exit. The two reels will not overlap on the same plane, structurally eliminating the risk of the wire 12 tangling. Subsequently, the tail end of the wire 12 passes through the wire storage frame 1, tensioning plate 22, twisting plate 23 and double guide roller 26 in sequence, and finally enters the guide pull wheel 11. During this process, the stop cone column 24 forms a suitable wire passage with the tensioning plate 22 and the twisting plate 23, ensuring that the wire 12 always maintains a stable fit with the outer periphery of the two reels. Thanks to the inclined setting of the tensioning plate 22 and the twisting plate 23, the wire inlet direction and the wire outlet direction of the wire 12 form a natural spatial angle, so that the wire 12 is tensioned and conveyed between the two reels in a Z-shaped structure. This Z-shaped path allows the wire 12 to be subjected to two lateral forces in opposite directions. The two forces cancel each other out, which can effectively avoid the torsional stress generated by the wire 12 during the wire storage process, and ensure that the cable always maintains a straight posture throughout the storage and release process.

[0072] refer to Figure 3 and Figure 4 As shown, when it is necessary to adjust the height of the retaining cone 24 and ensure that its inclined surface is synchronously adapted to the tensioning disc 22 and the tightening disc 23 after adjustment, the outer threaded ring 46 can be rotated to form a helical fit with the inner threaded ring 45. Then, the outer threaded ring 46 moves from bottom to top along the inside of the inner threaded ring 45, synchronously driving the connecting piece extrusion groove 47 to move upward. As the connecting piece extrusion groove 47 moves upward, the contact force between its inner side and the outer side of the three elastic arc pads 44 gradually weakens. The three elastic arc pads 44 contract under their own elastic force, forming a gap with the outer periphery of the locking post 42, thereby releasing the limiting constraint of the locking post 42 in the conical ring 43.

[0073] Then, pulling the stop cone 24 will cause the locking pin 42 to adjust up and down along the inside of the conical ring 43. At the same time, the stop cone 24 can be rotated synchronously, so that the inclined rhomboid surface of the stop cone 24 maintains a suitable slope with the tensioning plate 22 and the tightening plate 23. After the adjustment is in place, the rhomboid surface of the stop cone 24 can apply a gentle limiting force to the upper line 12, effectively preventing the line 12 from detaching from the wheel surface of the tensioning plate 22 and the tightening plate 23. Moreover, the inclination angle of the rhomboid surface and the inclination angle of the two plates form a mechanical fit, and the limiting force can be transmitted along the tangential direction of the movement direction of the line 12, without generating compressive stress perpendicular to the surface of the insulation layer, thereby preventing hard contact from damaging the insulation layer.

[0074] refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, when the production line 12 moves through the double guide rollers 26 to the guide wheel 11, the first contact frame 52 and the second contact frame 54 can switch to achieve two different contact constraint states. The specific actions and synergistic effects are as follows:

[0075] Firstly, in both normal guiding and abnormal anti-torsion constraint states: the second electric telescopic rod 51 drives the insertion cone 56 to move synchronously, thereby displacing the locking cone 55 and driving the first contact frame 52 to move horizontally along the top of the support frame 25, ultimately forming contact with the outer periphery of the line 12. Relying on its W-shaped structure, after the first contact frame 52 contacts the line 12, it forms multiple continuous arc-shaped support points, constructing a segmented guiding channel adapted to the transmission trajectory of the line 12. This achieves multi-node limiting of the line 12, standardizing its transmission path from both sides and effectively suppressing lateral deviation. Simultaneously, the undulating surface of the corrugated auxiliary contact frame 53 flexibly conforms to the outer periphery of the line 12, providing lateral contact force while increasing contact friction through the undulating structure, further... To improve guiding stability, when an abnormality occurs at the front end of the cable 12 affecting normal cable storage, the second electric telescopic rod 51 continues to drive the first contact frame 52 to move closer to the corrugated auxiliary contact frame 53, so that the cable 12 is slightly clamped between the first contact frame 52 and the corrugated auxiliary contact frame 53. At this time, the multi-node lateral limiting of the W-shaped first contact frame 52 can restrict the circumferential rotation space of the cable 12. Combined with the friction between the undulating surface of the corrugated auxiliary contact frame 53 and the cable 12, a circumferential constraint force is formed, which effectively suppresses the torsional tendency during transmission. The clamping structure formed by the symmetrical distribution of the two firmly confines the cable 12 between the two sides. Through multi-node interlocking, the lateral constraint is strengthened and the anti-slip performance is improved, which greatly enhances the safety and reliability of the cable storage process.

[0076] refer to Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, secondly, the full-circumference limiting and emergency stop buffer protection state: the second electric telescopic rod 51 drives the insertion cone 56 to move, causing the locking cone 55 to move synchronously, thereby driving the second contact frame 54 to move horizontally along the top of the support frame 25, forming contact with the outer circumference of the line body 12. Relying on its own circular structure, the second contact frame 54 forms a full-circumference fit after contacting the line body 12, providing uniform lateral constraint force from all circumferential angles, constructing a semi-enclosed limiting structure, ensuring that the line body 12 is subjected to balanced circumferential force, without local high-voltage areas. When an abnormality occurs at the front end of the line body 12 and emergency interruption of line storage is required, the second contact frame 54... The silicone contact surface of the frame 54 quickly locks the circumferential position of the line 12, preventing it from shifting or twisting due to inertia. At the same time, the circular structure distributes the locking force evenly around the outer periphery of the line 12, eliminating local stress concentration. During this process, the corrugated auxiliary frame 53 absorbs the axial impact stress at the moment of locking through elastic deformation, buffering the rebound tendency of the line 12. Together with the second abutment frame 54, it forms a double protection of "circumferential fixation and axial buffering", ensuring a smooth and damage-free emergency stop process. This synergistic cooperation not only enhances the stability of emergency stop locking, but also avoids secondary damage that may be caused by rigid locking.

[0077] refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, when it is necessary to quickly replace the first contact frame 52 and the second contact frame 54 (the connection structure of the two with the second electric telescopic rod 51 is the same), the replacement operation procedure is as follows: First, push the push frame ring 57 to move horizontally along the outer periphery of the insert cone cylinder 56, and the arc frame 59 moves synchronously along the outer periphery of the insert cone cylinder 56 with the push frame ring 57; during the displacement, the inner side of the arc frame 59 slides away from the outside of the shifting column roller ball 501, so that the shifting column roller ball 501 loses the contact constraint of the arc frame 59 and can move freely along the shifting column roller groove 502 and the inner side of the working ring recess 503. Then, pull the contact frame to be disassembled (taking the first contact frame 52 as an example), which drives the locking cone 55 fixed to it to move synchronously along the inside of the insert cone cylinder 56. During the displacement of the locking cone 55, The synchronous movement of the working ring recess 503 causes the inner side of the working ring recess 503 to abut against the bottom of the shifting roller ball 501, thereby pushing the shifting roller ball 501 to reset along the inside of the working ring recess 503 into the shifting roller groove 502. The bottom of the shifting roller ball 501 and the top of the working ring recess 503 maintain a smooth sliding fit, continuously pulling the contact frame. The locking cone 55 drives the working ring recess 503 to continue moving, so that the shifting roller ball 501 completely disengages from the limiting area of ​​the working ring recess 503. The locking cone 55 can then be completely pulled out from the inside of the insert cone cylinder 56, completing the disassembly of the contact frame to be disassembled. Conversely, the target contact frame is installed according to the same principle to achieve rapid switching and replacement of the first contact frame 52 and the second contact frame 54.

[0078] refer to Figure 5 , Figure 9 and Figure 10As shown, when the yarn 12 is clamped and pressed against by the first abutting frame 52 and the auxiliary abutting frame 53, firstly, the first abutting frame 52 pushes the yarn 12 closer to the auxiliary abutting frame 53, and the outer periphery of the yarn 12 then forms contact with the extrusion arc plate 67. Under the action of this contact force, the extrusion arc plate 67 drives the centering shaft 65 to move synchronously to the guide groove 35. At this time, the return spring 62 between the auxiliary abutting frame 53 and the slide 61 is compressed, and its own elastic force is applied in the opposite direction to the slide 61, so that the extrusion arc plate 67 always maintains stable contact with the outer periphery of the yarn 12. Then, the displacement of the slide 61 synchronously drives the two centering shafts 65 to move, and the outer periphery of the centering shaft 65 forms contact with the inner side of the two abutting rods 66, thereby driving the two abutting rods 66 to move synchronously. Meanwhile, under the limiting action of the guide post 64, the movement path of the two abutment rods 66 is precisely constrained, and they tilt and displace along the side of the slide block 61 and the column 63. Subsequently, the included angle between the two abutment rods 66 changes, and they always maintain contact with the outer periphery of the line body 12 during the displacement process. As the abutment rods 66 tilt and move, they drive the guide post 64 to move closer to the line body 12 along the outer periphery of the column 63, thereby achieving secondary limiting of the line body 12 on both sides of the auxiliary abutment frame 53. Finally, the first abutment frame 52 and the auxiliary abutment frame 53 work together to stably limit the line body 12 within the optimal clamping range, strengthen the constraint stability of the outer periphery of the line body 12 on both sides of the auxiliary abutment frame 53, and ensure that the line body 12 always maintains a stable posture under working conditions such as emergency stop.

8. The method of using the wire storage device for physically foamed insulated coaxial cable according to claim 7, characterized in that, Includes the following steps; S1. First, the height and angle of the stop cone (24) at the top of the bracket (21) are adjusted by the tensioning component (4), so that the outside of the stop cone (24) is in a suitable position with the tensioning plate (22) and the torque plate (23). As the stop cone (24) is adjusted, a passive limiting channel is formed around the outer periphery of the tensioning plate (22) and the torque plate (23). Then, the tilt angle is dynamically adjusted according to the infeed posture and specifications of the line (12), generating a lateral component force along the tangent direction of the wheel surface, continuously guiding the line (12) to the center of the wheel surface, ensuring that the line (12) moves along the outer periphery of the tensioning plate (22) and the torque plate (23), and suppressing the tendency of deviation from the source. S2. Next, the wire body (12) is passed through the wire storage frame (1), tensioning disc (22), twisting disc (23), double guide roller (26) and guide pull wheel (11) from left to right to enable the wire body (12) to continuously wind and store the wire. Then, the tilting assembly (3) is used to adjust the tilt angle between the twisting disc (23) and the tensioning disc (22) so that the twisting disc (23) and the tensioning disc (22) maintain a tilted and intersecting Z-shaped path, so that the wire body (12) forms an elastic zigzag contact on the outer periphery of the twisting disc (23) and the tensioning disc (22). S3. Secondly, after the end of the line (12) is inserted into the double guide roller (26), the outside of the line (12) is surrounded by the limiting component (5). During the period when the line (12) is surrounded by the limiting component (5), the dynamic contact force between the line (12) and the tightening disc (23) is adjusted. When the tension is too small, the contact force is increased to supplement the tension and prevent the cable from loosening. When the tension is too large, the contact force is reduced to release the excess tension and prevent the insulation layer from stretching. The two work together to keep the end tension in the optimal range, reduce the slippage of the line (12) at the end tightening disc (23) and the double guide roller (26), and ensure the stable wire storage operation of the line (12). S4. Finally, after the end of the cable storage in the cable body (12) is completed, the limiting component (5) locks the cable body (12) at the guide wheel (11) to ensure that the cable body (12) remains sufficiently stable at the guide wheel (11). During the process of the cable body (12) being pushed and locked by the limiting component (5) in a passive state, the cable body (12) and the clamping component (6) remain in contact. Then the clamping component (6) temporarily restricts the outside of the cable body (12) to further improve the stability of the cable body (12) at the guide wheel (11).
