Description

Technical Field

[0001] The invention relates to the field of insulation layer coating, in particular to equipment capable of coating the insulation layer of a cable. Background Art

[0002] The cable insulation layer is a layer of non-conductive material wrapped around the cable conductor. Its main function is to isolate the conductor from the external environment and prevent current leakage and short circuit.

[0003] The cable insulation layer is mainly coated on the outside of the cable through a cable insulation coating machine, and the cable insulation coating machine mainly includes an extruder body, a wire-releasing device, a traction device, a cooling system, a wire-reeling device, and a control system. A head and a mold are arranged on the extruder body. When the metal wire core passes through the mold, the extruder heats and melts the raw materials used for the insulation layer such as polyvinyl chloride and extrude them through the mold on the outside of the metal wire core to achieve coating.

[0004] However, when the existing cable insulation coating machine coats the insulating material on the outside of the metal wire core, the insulating material is in a molten state.

[0023] Furthermore, the upper and lower slide plates 7 are fixedly connected to a support 8 on one side close to each other, and the arc-shaped cleaning cotton 9 is installed on the support 8 on each side by bolts. The outer side of the slide bar 4 is provided with a tension spring 10, and the two ends of the tension spring 10 are respectively slidably connected to the slide plate 7 and the slide bar 4. A limit block 47 is slidably connected in the slide rail 2, and the upper end of the limit block 47 is connected to a push rod motor 48, and the output end of the push rod motor 48 is connected to the lower end of the bonding treatment box 3, as shown in FIG. Figure 5 As shown, the arc-shaped cleaning cotton 9 is installed on the support 8 by bolts, which is convenient for replacing the arc-shaped cleaning cotton 9 after long-term use. The setting of the tension spring 10 can make the slides 7 on the upper and lower sides move away from each other without the action of external force, keeping the upper and lower parts of the arc-shaped cleaning cotton 9 separated. The limit block 47 is slidably connected in the slide rail 2 and connected to the bonding processing box 3 through the push rod motor 48, which can not only stabilize the sliding of the bonding processing box 3, but also facilitate the synchronous use of each push rod motor 48 to adjust the height of the bonding processing box 3, so that it can be convenient to keep coaxial with the metal wire core passing through the head mold 6.

[0024] Further, the driving assembly 1 includes an inclined block 11, a mounting seat 12, a telescopic member 13, a slide frame 14, and a push plate 15.

Figure 6As shown, by extending and retracting the telescopic member 13, the slide frame 14 can drive the push plate 15 to move, and the push plate 15 can contact with the inclined block 11, and push the upper and lower slide plates 7 to approach each other, so that the upper and lower arc-shaped cleaning cottons 9 can approach each other and fit the metal wire core passing therebetween, so that the metal wire core is wiped clean before passing through the head mold 6 and being coated with the insulating material, thereby ensuring the tightness of the subsequent molten insulating material and the metal wire core coating, thereby improving the stability of the insulating layer and the metal wire core in the finished cable, thereby increasing the service life.

[0025] Furthermore, the support platform 1 is connected with a guide rod 16, the slide frame 14 is slidably sleeved on the outer side of the guide rod 16, and a connecting frame 17 is connected to the side of the processing box 3. A rotating plate 18 is rotatably connected between the slide frame 14 and the connecting frame 17. Figure 5 As shown, when the telescopic member 13 is extended to drive the arc-shaped cleaning cotton 9 on the upper and lower sides closer to each other, it can also drive the rotating plate 18 to rotate, and push the connecting frame 17 and the bonding processing box 3 connected thereto with one side of the support table 1 to move to a position corresponding to the coaxial position of the head mold 6, so as to facilitate the coordinated use between the arc-shaped cleaning cotton 9 and the bonding processing box 3.

[0026] Further, a base 19 is connected to the lower inner wall of the treatment box 3, and a ring 20 is connected to the base 19. The rotating ring 21 is rotatably mounted on the outer side of the ring 20. A spring 28 is also connected between the slider 26 and the inner wall of the slideway groove 25. One end of the slider 26 extends through the slideway groove 25 to the center of the rotating ring 21, and a pressure strip 27 is connected to the extended end. Figure 4 As shown, the rotating ring 21 can be stably rotated in the fitting processing box 3 by rotating with the circular ring 20. At the same time, the setting of the spring 28 can ensure that the sliders 26 sliding in the slide grooves 25 arranged in an array on the same rotating ring 21 can be away from each other without the action of external force, and drive the pressure strips 27 arranged in an array on the same rotating ring 21 to be in positions away from each other.

[0027] Furthermore, the second driving component includes a slide rod seat 22, a slip ring 23, a spring 24, a bevel gear 30, a driving motor 31, and a top frame 35. The slide rod seat 22 is connected to the rotating ring 21 in an array. The slip ring 23 is slidably sleeved on the outer side of the slide rod seat 22. The spring 24 is sleeved on the outer side of the slide rod seat 22. The two ends of the spring 24 are respectively connected to the slip ring 23 and the rotating ring 21. A rotating plate 29 is rotatably connected between each slider 26 and the slip ring 23 on each side. The bevel gear 30 is sleeved on the outer side of the rotating ring 21. The driving motor 31 is symmetrically connected to the upper and lower inner walls of the fitting treatment box 3. The output end of the driving motor 31 is connected to the bevel gear 2 32 meshing with the bevel gear 30. The top frame 35 is connected to the output end of the driving motor 31. The top frame 35 and the slip rings 23 slidingly arranged on the sides of the rotating rings 21 close to each other slide in contact with each other. Figure 4 , 9 As shown in Figure 10, by starting the driving motor 31, the top frames 35 on both sides can be driven to rotate, thereby contacting the slip rings 23 on both sides on the slide rod seats 22 to reciprocate and approach each other and compress the spring 1 24, or move away from each other under the elastic force of the spring 1 24, so as to drive each rotating plate 29 to rotate, push each slider 26 and the pressure strip 27 connected thereto to approach or move away from each other, and compress the insulating material coated on the outside of the metal wire core, so that the insulating material can fit more closely with the metal wire core.

[0028] When the driving motor 31 is running, it will also drive the bevel gear 2 32 to rotate, and then drive the bevel gear 1 30 mounted on the rotating ring 21 which is meshed with it to rotate, and drive the rotating rings 21 on both sides to rotate, so that the pressure strip 27 can not only press the insulating material on the outside of the metal wire core, but also rotate, and evenly press the insulating material on the outside of the metal wire core, and avoid pressing only on the same side, so that the insulating material is evenly pressed and fits the outside of the metal wire core.

[0029] Furthermore, the output end of the driving motor 31 is connected to a square seat 33, and the square seat 33 is located on the side of the bevel gear 2 32 away from the driving motor 31, and both ends of the square seat 33 are connected to the telescopic member 2 34, and the top frame 35 is symmetrically arranged on both sides of the square seat 33 and connected to the telescopic member 2 34 on each side, and the outer side surface of the top frame 35 is rotatably mounted with multiple rollers 36 at equal intervals, such as Figure 4 , 9 As shown in 10, by setting the roller 36, when the rotating ring 21 is driven by rotation, it can form a rolling connection between the roller 36 and the top frame 35, while the top frame 35 can still smoothly push the slip rings 23 on both sides that rotate with the rotating ring 21, and the setting of the telescopic member 24 can adjust the distance between the top frames 35 on both sides to change the amplitude of pushing the slip rings 23 on both sides, and then adjust the range of movement of each pressure strip 27 to approach each other, so as to facilitate the compression and fitting of the surface insulation materials of cables with different diameters.

[0030] Further, the base 19 is connected to an annular seat 37, an annular tube 38 is sleeved on the outer side of the annular seat 37, and a nozzle 39 is connected to the annular tube 38 in a direction parallel to the axial direction, and a plurality of nozzles 40 are installed in an array on the nozzle 39, and a connecting rod 41 is connected to the ring 20, and a scraper 42 that slides in contact with the inner wall of the contact treatment box 3 is connected to the connecting rod 41, and the annular tube 38 is fixedly connected to the connecting rod 41, as shown in FIG. Figure 4 and 9As shown, when the rotating ring 21 is driven to rotate, it can also drive the annular tube 38, the spray pipe 39, and the nozzle 40 connected to the connecting rod 41 to rotate, so that the nozzle 40 can spray out cooling water to cool down the insulating material on the outside of the metal wire core before being squeezed by the pressure strip 27, so as to avoid excessive deformation of the insulating material when the pressure strip 27 presses it. At the same time, since the annular tube 38 is arranged at the front and rear ends of the bonding treatment box 3, the insulating material on the outside of the metal wire core after being squeezed by the pressure strip 27 can be cooled again, and the scraper 42 can also follow the rotating ring 21 to slide in the bonding treatment box 3 and fit with its inner wall, and scrape and collect the water droplets on the inner wall of the bonding treatment box 3 that may be generated by the nozzle 40 spraying cooling water.

[0031] Furthermore, a collecting bin 49 is connected to the bottom of the laminating treatment box 3, and a collecting port 43 and a slideway port 44 are provided between the collecting bin 49 and the laminating treatment box 3. Both sides of the slip ring 23 are connected to vertical plates 45, and the lower end of the vertical plate 45 slides through the slideway port 44 and extends into the collecting bin 49, and a stirring ring 46 is connected to the extended end. Figure 8 As shown, since the vertical plate 45 slides in the slide opening 44 that passes through the bonding treatment box 3 and the collecting bin 49, after the scraper 42 scrapes off the water droplets on the inner wall of the bonding treatment box 3, the water droplets can be collected into the collecting bin 49 through the collecting opening 43. At the same time, the sliding of the slip ring 23 can drive the vertical plate 45 and the stirring ring 46 connected to the lower end of the vertical plate 45 to stir back and forth in the collecting bin 49, so as to increase the cooling rate of the cooling water collected in the collecting bin 49.
