TECHNICAL FIELD

[0001] The present application relates to the technical field of cable coating, in particular to a wire core intelligent coating device and method for wire and cable processing. BACKGROUND

[0002] An electric wire is composed of one or several soft conductive wires, and the outside is wrapped with a soft protective layer. A cable is composed of one or several insulated conductive wires, and the outside is wrapped with a tough outer layer made of metal or rubber. Both the electric wire and the cable are generally composed of a core wire, an insulation sheath and a protective outer sheath. In the processing of the electric wire and the cable, a coating device is needed to coat an insulation layer and a protective layer on the surface of the metal conductive wire. The manufacture of the electric wire and the cable belongs to the subdivision field of "electric wire, cable, optical cable and electrical equipment manufacturing" in the electrical machinery and equipment manufacturing industry, and the core link (such as power distribution, power transmission and power consumption) of the smart grid industry highly depends on high-performance cable products. The wire core coating device, as a key equipment for cable production, directly serves the manufacture of power cables and belongs to the upstream supporting link of the smart grid industry chain.

[0003] Referring to the patent application with the publication number CN120261063A, a cable processing device for facilitating cable core coating and forming is disclosed, which includes a processing table, the top of the processing table is fixedly connected with a processing top box, the left side of the processing top box is provided with an inlet box, the top of the inlet box is communicated with an inlet pipe, the cable wire passes through the inlet box and the processing top box for coating treatment, the cooperation of the pressure wheel and the stop rod applies uniform pressure to the cable coating layer, effectively eliminates the air bubbles generated in the coating process, and the rotation of the rotating roller can drive the cable to rotate, so that the cable can be uniformly affected by the pressure defoaming mechanism in the coating process, thereby effectively eliminating the air bubbles around the cable, significantly improving the mechanical strength of the coating layer, avoiding the cracks, damages or breakage problems caused by air bubbles, and prolonging the service life of the cable.

[0004] In the traditional insulation layer cooling link in the processing of the electric wire and the cable, a straight cylinder type cooling tank is generally used, and the uniform cooling mode is easy to cause thermal stress concentration of the molten insulation layer due to sudden temperature difference, thereby causing problems such as crystallization defects or uneven radial shrinkage. In the prior art, the static water cooling system cannot dynamically adjust the cooling intensity according to the real-time temperature distribution of the insulation layer, and the mechanical stirring device has defects such as single water flow speed and large energy loss. In addition, the surface temperature detection of the cable wire mostly uses fixed interval contact type sensors, which is difficult to adapt to the dynamic changes of the insulation layer thickness on the high-speed production line, resulting in insufficient quality control precision.

[0005] Therefore, it is necessary to provide a wire core intelligent coating device and method for wire and cable processing to solve the above technical problems. SUMMARY

[0017] Compared with the prior art, the present application has the following advantages: 1. The tapered transition section can realize gradient distribution of cooling water pressure, so that the cable insulation layer experiences a cooling process from weak to strong, and this gradual cooling mechanism effectively avoids the thermal stress concentration problem caused by sudden temperature difference in the traditional straight cylinder type cooling tank, and especially for the rapid shrinkage phenomenon of the molten insulation layer when entering water at high temperature, through the synergistic regulation of water flow speed and cooling intensity, the insulation layer forms uniform radial shrinkage force distribution in the cooling process.

[0019] 3. The water flows through the flow channel, creating a relative eddy current. When the second magnetic plate leaves its effective range, the 3N elastic force released by the first spring causes the guide plate to return to its working angle within 0.5 seconds via the traction rope, forming a periodic opening and closing pulse.

When the blocking rod is removed, the metal plate will descend under the action of the third spring and contact the insulation layer on the surface of the cable. This avoids the error caused by unevenness in the initial position. Attached Figure Description

The cooling mechanism comprises two fixed discs 5 fixedly connected to both ends inside the cooling tank 2, and an annular air bag 4 arranged between the two fixed discs 5, and an adjusting assembly arranged between the two ends of the annular air bag 4, for adjusting the radius of the annular air bag 4, and an agitating assembly arranged inside the annular air bag 4. The fixed frame 3 is fixedly connected to one end of the cooling tank 2 away from the plastic extruder 1, and one side of the fixed frame 3 is rotatably connected with a first outer gear ring 300, the outer side of the first outer gear ring 300 is meshingly connected with a first gear 302, the first gear 302 is rotatably connected with the fixed frame 3, the inner wall of the first outer gear ring 300 is fixedly connected with a magnet ring 301, the inner side of the magnet ring 301 is fixedly connected with a plurality of mounting frames 6, and the outer side of the mounting frame 6 is provided with a detection assembly for detecting the flatness of the outer insulation layer of the cable.

[0027] In specific implementation, after the cable is covered with an insulation layer through the mold 101, the cable passes through the cooling tank 2 and the fixed frame 3 in sequence, the cable is cooled by the cooling mechanism inside the cooling tank 2, the cable passes through the agitating assembly inside the annular air bag 4, the cooling water cable is fully contacted through the agitating assembly, when the cable cooling is completed, the cable passes through the fixed frame 3, the first outer gear ring 300 is rotated, the plurality of detection pieces inside the magnet ring 301 detect the flatness of the surface of the cooled cable, and the cable insulation layer is fully cooled after passing through the cooling tank 2 through the agitating assembly.

[0028] In this embodiment, the adjusting assembly comprises a plurality of racks 501, the plurality of racks 501 are slidably connected with the fixed disc 5, and the plurality of racks 501 are arranged in a ring around the center of the fixed disc 5, one end of the plurality of racks 501 is fixedly connected with one end of the annular air bag 4, the outer side of the plurality of racks 501 is meshingly connected with a third gear 502, the outer side of the third gear 502 is fixedly connected with a transmission rod 504, the transmission rod 504 penetrates through the fixed disc 5 and is rotatably connected with the fixed disc 5, one end of the transmission rod 504 is fixedly connected with a fourth gear 503, the other side of the fixed disc 5 is rotatably connected with a second inner and outer gear ring 505, and the second inner and outer gear ring 505 is meshingly connected with the plurality of fourth gears 503.

The tapered structure can form Bernoulli effect, so that the water flow speed in the narrow section is increased by 1.5-2 times, and the cooling efficiency is enhanced. In the case of normal water flow, the cooling efficiency of the cooling water is adjusted to gradually cool the cable and avoid sudden drop. The tapered design produces double effects through Bernoulli effect: on the one hand, the water flow speed at the narrow inlet can be increased by 1.5-2 times, and the impact cooling effect on the cable is enhanced; on the other hand, the tapered transition section can realize gradient distribution of the cooling water pressure, so that the cable insulation layer experiences a cooling process from weak to strong. This progressive cooling mechanism effectively avoids the thermal stress concentration problem caused by sudden temperature difference in the traditional straight cylinder type cooling tank. Especially for the rapid shrinkage of the molten insulation layer when entering water at high temperature, the water flow speed and the cooling intensity are cooperatively controlled to form uniform radial shrinkage force distribution of the insulation layer in the cooling process.

[0030] In the embodiment two, the stirring assembly comprises a cooling cylinder 401. A plurality of flow grooves 4010 are formed in the outer side of the cooling cylinder 401.

[0031] The transmission member comprises a first inner and outer gear ring 403. The first inner and outer gear ring 403 is rotatably connected to one end inside the cooling tank 2. A plurality of first fixed rods 404 are fixedly connected to the outer side of the first inner and outer gear ring 403.

The output shaft of the first motor is fixedly connected with the third gear ring 408.

[0032] In actual implementation, when it is necessary to adjust the temperature between the stepwise cooling areas in the cooling water to realize the radial temperature gradient control of the cable, in the scheme, the cable passes through the cooling cylinder 401, when it is necessary to adjust the cooling of the outside of the cable, the first motor is started, the output shaft of the first motor drives the third ring gear 408 to rotate, the third ring gear 408 drives the meshed first inner and outer gear 403 to rotate, the first inner and outer gear 403 drives the stirring blade 402 to rotate through the first fixed rod 404, the stirring blade 402 rotates spirally outside the cooling cylinder 401, drives the water to flow spirally, at the same time, the first inner and outer gear 403 drives the second outer gear 406 to rotate through the second gear 405, the second outer gear 406 drives the second fixed rod 407 to rotate, the second fixed rod 407 drives the cooling cylinder 401 to rotate, so that the cooling cylinder 401 and the stirring blade 402 rotate in opposite directions, and cooperate with the annular air bag 4 outside the stirring blade 402, through the change of the radius of the annular air bag 4, the relative motion generates a shear field, so that the cooling water forms a three-dimensional vortex, and the radius of the annular air bag 4 is dynamically adjusted through the micro motor control rack group, so that the water flow velocity distribution can be accurately adjusted, when it is necessary to enhance the cooling strength, the annular air bag is contracted to form a high-pressure area, and the water flow is accelerated through the narrow channel; when it is necessary to moderate the cooling, the air bag is expanded to reduce the flow rate, and the dynamic adjustment mechanism enables the cooling water to form a temperature gradient from the surface to the inside in the radial direction according to the real-time temperature distribution of the cable insulation layer, thereby avoiding the problem of stress concentration in the insulation layer caused by traditional uniform cooling.

[0033] In the embodiment, the guide plate 4011 is arranged at the flow channel 4010, the middle part of the guide plate 4011 is fixedly connected with a connecting rod, the connecting rod is rotatably connected with the cooling cylinder 401, and the connecting rod and the cooling cylinder 401 are fixedly connected with a torsional spring. The inner wall of the cooling cylinder 401 is fixedly connected with a limiting frame 4013, the limiting frame 4013 is slidably connected with a first magnetic plate 4014 outside, the first magnetic plate 4014 is fixedly connected with a traction rope 4015 at one end of the guide plate 4011, the traction rope 4015 passes through the limiting frame 4013, the first spring 4016 is fixedly connected between the limiting frame 4013 and the first magnetic plate 4014, a plurality of second magnetic plates 4021 are fixedly connected outside the stirring blade 402, the second magnetic plates 4021 are spirally distributed along the stirring blade 402, the second magnetic plates 4021 and the first magnetic plate 4014 repel each other magnetically, when the second magnetic plates 4021 approach the first magnetic plate 4014, the first magnetic plate 4014 is pushed to move towards the guide plate 4011, so that the torsional spring on the connecting rod resets to drive the traction rope 4015 to rotate and be attached to the cooling cylinder 401.

[0034] In the above scheme, when the cooling cylinder 401 and the stirring blade 402 rotate relative to each other, a plurality of flow channels 4010 are formed on the outer side of the cooling cylinder 401, and a guide plate 4011 is arranged at the flow channel 4010. When the cooling cylinder 401 rotates, the guide plate 4011 is blocked by the first magnetic plate 4014 and the traction rope 4015 on the guide plate 4011, and the water flow is forced to flow into the cooling cylinder 401 through the flow channel 4010, so that the water flow forms a relative vortex, thereby improving the cooling effect of the water on the cable. When the stirring blade 402 rotates, a plurality of second magnetic plates 4021 are fixedly connected to the stirring blade 402. When the second magnetic plate 4021 approaches the guide plate 4011, the second magnetic plate 4021 and the first magnetic plate 4014 repel each other magnetically, so that the first magnetic plate 4014 presses the first spring 4016 on the limiting frame 4013. At this time, the first magnetic plate 4014 and the traction rope 4015 on the guide plate 4011 are relaxed. At this time, the torsional spring drives the connecting rod to rotate, the connecting rod drives the guide plate 4011 to reset, the guide plate 4011 is consistent with the surface of the cooling cylinder 401, and the stirring blade 402 can rotate smoothly outside the cooling cylinder 401. When the second magnetic plate 4021 rotates, the first spring 4016 pushes the first magnetic plate 4014 to move, the first magnetic plate 4014 pulls the guide plate 4011 through the traction rope 4015, and the cooling water is blocked by the guide plate 4011 and flows into the flow channel 4010 to form a relative vortex. When the second magnetic plate is out of the effective range, the 3N elastic force released by the first spring 4016 makes the guide plate restore the working angle within 0.5 seconds through the traction rope 4015 to form a periodic opening and closing pulse. This magnetic-mechanical-liquid coupling mechanism can realize a water flow impact frequency of 2-4 times per second to control the cable surface temperature gradient and effectively avoid crystallization defects caused by rapid cooling of the molten insulation layer. It is worth noting that during the rotation of the cooling cylinder 401, the first magnetic plate 4014 fixed on the cylinder wall continuously pulls the guide plate 4011 through the traction rope 4015, so that the guide plate 4011 is deflected at an angle of 15°-30° to block the water flow, forcing the cooling water to vertically enter the cylinder body through the flow channel to form a spiral vortex at an angle of 45° with the cable axis. The vortex structure can increase the contact area between the cooling water and the cable, and the high-temperature water film is quickly stripped off by the centrifugal force.
