[0022] Working principle: the insulation cable production extrusion shaping device realizes the full-automatic production process through the processes of cable conductor pay-off, insulation layer melting and extrusion, outer surface smoothing and cooling and take-up, and the specific working steps are as follows: (I) pay-off stage: stable conveying of cable conductor; Power drive: start the first motor 206 in the pay-off mechanism 2, and the output end drives the first belt pulley 207 to rotate, and through the transmission action of the first belt 211, the second belt pulley 208, the third belt pulley 209 and the fourth belt pulley 210 are synchronously driven to rotate.

[0023] Synchronous conveying: the above-mentioned belt pulleys are fixedly connected with the first conveying roller 202, the second conveying roller 203 and the third conveying roller 204 respectively, thereby driving the three conveying rollers to rotate synchronously, at the same time, the first auxiliary roller 205 assists in supporting the cable conductor, so that the conductor keeps stable and has no deviation during the conveying process, thereby providing a stable base material conveying basis for the subsequent insulation layer extrusion shaping.

[0024] (II) molten material pushing stage: insulation raw material melting and directional conveying; Structure adaptation explanation: the feeding pipe 402 adopts an axial segmented design of "top feeding-middle melting-bottom discharging", the feeding port is arranged at one side of the top end of the feeding pipe 402, the passing port is arranged at the bottom of the feeding pipe 402 away from the feeding port, and the feeding port and the passing port are distributed in a staggered manner along the axis of the feeding pipe 402, thereby forming a one-way conveying channel, so that the raw material is prevented from directly entering the shaping bin 302 without being melted, the heating bin 403 covering the middle region of the feeding pipe 402 is arranged outside the feeding pipe 402, thereby ensuring that the raw material has enough heating length in the feeding pipe 402 to complete the melting; Raw material melting process: the insulation layer raw material (such as plastic particles) is put into the storage bin of the molten material pushing mechanism 4, the raw material falls into the inside of the feeding pipe 402 through the feeding port, at the same time, the electric heating wire 405 in the heating bin 403 is electrified to generate heat, the heat is uniformly conducted to the raw material in the pipe through the pipe wall of the feeding pipe 402, so that the raw material is gradually melted from solid to liquid insulation material with good fluidity, and the temperature control system of the heating bin 403 can monitor and maintain the melting temperature in real time, thereby ensuring that the insulation material melting state is stable; Power transmission and directional pushing: start the second motor 407, the output end drives the driving rod 408 to rotate, the second sprocket 409 on the driving rod 408 drives the first sprocket 406 to rotate through the chain 410; the first sprocket 406 is fixedly connected with the spiral pushing rod 404 in the feeding pipe 402, the spiral pushing rod 404 rotates in an axial direction of the feeding pipe 402, the spiral blade of the spiral pushing rod 404 is tightly fitted with the inner wall of the feeding pipe 402, and the continuous axial thrust is generated by the spiral lead angle, so that the liquid insulation material in the middle of the feeding pipe 402 is gradually pushed to the bottom passing port along the inner wall of the pipe, and the spiral blade can prevent the liquid insulation material from flowing back in the process, thereby ensuring that the conveying direction is stable; Precise delivery to the shaping bin: After the liquid insulation material flows out of the bottom of the feeding pipe 402 through the material outlet, it is delivered to the shaping bin 302 of the extrusion shaping mechanism 3 through the special connecting pipe 7. The connecting pipe 7 is sealingly connected with the material outlet and the feeding end of the shaping bin 302 to prevent leakage of the liquid insulation material, complete the closed-loop process of the insulation material from melting to delivery, and ensure that the pushing function of the spiral pushing rod 404 is accurately matched with the melting state of the raw material.

[0025] (Three) extrusion shaping and smoothing stage: insulation layer covering and surface optimization; Insulation layer extrusion: After the liquid insulation material enters the shaping bin 302, it meets the cable conductor delivered from the pay-off mechanism. Under the constraint of the cavity structure of the shaping bin 302, the insulation material tightly covers the outside of the conductor, and the rudiment of the insulated cable is initially formed.

[0026] Synchronous smoothing and inner wall cleaning: while the second motor 407 drives the driving rod 408 to rotate, the first gear disc 307 on the driving rod 408 meshes with the first gear ring 306 on the linkage sleeve 303 in the shaping bin 302 to drive the linkage sleeve 303 to rotate. The linkage plate 304 on the linkage sleeve 303 synchronously performs circular motion, and the scraper 305 on the linkage plate 304 abuts against the outer surface of the extruded insulated cable on one hand to smooth the insulation layer in a circle, ensuring the uniform thickness and smooth surface of the insulation layer, and abuts against the inner wall of the shaping bin 302 on the other hand to scrape off the residual liquid insulation material on the inner wall, avoiding the influence of the solidified residual material on the subsequent cable shaping quality.

[0027] (Four) cooling stage: rapid cooling and shaping; Power driving and spraying preparation: while the extruded insulated cable enters the take-up mechanism 5, the fourth motor 606 in the cooling mechanism 6 is started, the output end of the fourth motor 606 drives the fifth pulley 607 to rotate, the second belt 609 drives the two sixth pulleys 608 to rotate synchronously, the sixth pulleys 608 are fixedly connected with the first connecting rod 604 and the second connecting rod 605, respectively, and then drive the second gear disc 610 and the third gear disc 611 on the two connecting rods to rotate.

[0028] Circular spraying cooling: the second gear disc 610 and the third gear disc 611 are in meshing transmission with the second gear ring 603 on the linkage ring 614 in the water cooling bin 601, which drives the linkage ring 614 to rotate, and the linkage frame 612 on the linkage ring 614 rotates synchronously. The water spraying panel 613 on the inner side of the linkage frame 612 sprays water cooling liquid to the surface of the cable through the array of spray heads, realizing 360° non-dead-angle rapid cooling of the insulation layer, avoiding deformation and wrinkles of the insulation layer due to untimely cooling, and recycling the water cooling liquid through the through hole at the bottom of the water cooling bin 601 to return to the water storage tank 602, reducing water consumption.

[0029] (five) winding stage: finished cable storage; Power drive and synchronous conveying: start the third motor 507 in the winding mechanism 5, the output shaft drives the driving gear 508 to rotate, the driving gear 508 on both sides is respectively engaged with the first driven gear 504 on the fourth conveying roller 502, the second driven gear 505 on the fifth conveying roller 503, and drives the fourth conveying roller 502 and the fifth conveying roller 503 to rotate synchronously.

[0030] Finished winding: the insulated cable after cooling and shaping is stably conveyed to the external winding equipment under the clamping and conveying of the fourth conveying roller 502 and the fifth conveying roller 503 and the auxiliary support of the two second auxiliary rollers 506, and the winding and storage of the finished cable are completed, and the whole production process is closed loop.
