Description

Technical Field

[0001] The present invention belongs to the technical field of cable processing equipment, and specifically relates to a cable threading device for cable wires. Background Art

[0002] A cable is a cable in the form of a rope formed by stranding several or several groups of wires. The wires in each group are insulated from each other and are often twisted around a central wire, and the whole is covered with a highly insulating covering layer. During the cable processing, after the cable is wound, a rubber protective sleeve with a protective function is usually wrapped outside it, and during the processing, an extruder is usually used to produce and process it in a wrapping form.

[0003] A patent with the publication number of CN117672639B discloses a cable threading device for cable processing. In this cable threading device for cable processing, when the cable wire passes through the center of the base hole, the annular threading block and the centering module in sequence, and the molten rubber is extruded into the annular flow channel by a rubber extruder, so that the annular flow channel is filled with the molten rubber fluid. As the cable wire continues to move, and by using the fact that the annular flow channel is generally circular, the rubber fluid can be evenly wrapped on the outer surface of the cable wire, thus facilitating the cable threading work.

[0004] In the above-mentioned prior art, when wrapping the insulating layer on the cable, it is necessary to wrap the molten rubber fluid outside the cable and pull out the cable. During this process, when a roll of cable processing is completed, it is necessary to replace the cable for processing, and it is necessary to place the end of the cable in the middle of the rubber extruder again. Since the temperature of the molten rubber is relatively high, it will cause the temperature inside the rubber extruder to be relatively high. When replacing the cable, generally, a worker wears gloves to pick up the cable and then places the cable in the middle of the rubber extruder, which has certain potential safety hazards.

[0018] 1. For a cable threading device of the present invention, by driving the second slider to drive the beveled-edge ring to slide along the bevel of the beveled-edge block, the beveled-edge block is driven to slide into the second ring at the same time. The beveled-edge block squeezes the first rectangular bar inward, driving the first cylindrical block to squeeze the cable inward at the same time to clamp the cable. Since a damper is installed between the first slider and the slide rail, when the second slider drives the beveled-edge ring to slide along the beveled-edge block, the first slider remains stationary. When the beveled-edge block completely slides into the second ring, the second slider is continuously driven to slide towards the side close to the second cylinder. At this time, the first slider is driven to slide towards the side close to the second cylinder through the conical cylinder.

Subsequently, the third circular ring is driven to rotate, and the fourth rectangular strip is driven to slide into the third cylinder simultaneously through the cylindrical strip. The fourth rectangular strip drives the second arc-shaped strip to slide towards the middle simultaneously through the first arc-shaped strip, clamping the end of the cable. Then, the second arc-shaped strip is driven to slide away from the second cylinder on one side of the first arc-shaped strip, and the arc-shaped rotating wheels rotate along one side of the first arc-shaped strip, causing several arc-shaped rotating wheels to rotate simultaneously. When the arc-shaped rotating wheels rotate, they drive the cable clamped in the middle to move away from the second cylinder. When the second arc-shaped strip completely slides into the first arc-shaped strip, it drives the cable through the middle of the circular tube and cools it. Subsequently, the cooled cable is manually pulled out, reducing potential safety hazards. At the same time, the end of the cable can extend out of one end of the first arc-shaped strip, facilitating subsequent pulling of the cable. Brief Description of the Drawings

Detailed implementation mode

[0030] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation modes. Embodiment 1

[0031] As Figures 1-3 shown, a cable threading device according to an embodiment of the present invention includes a workbench 1. A first rectangular plate 11 is fixedly connected to the upper end of the workbench 1. A second cylinder 2 is arranged on the upper end of the first rectangular plate 11. The lower end of the second cylinder 2 is fixedly connected to the first rectangular plate 11 through a fixed block 24. Clamping components are respectively arranged at both ends of the second cylinder 2. The clamping components include semicircular plates 22 which are respectively slidably connected to both sides of one end of the second cylinder 2. Circular holes 221 are respectively arranged in the middle parts of the semicircular plates 22. A first L-shaped pipe 21 is fixedly connected to the upper end of the second cylinder 2. A spiral heater 211 is fixedly connected to one end of the first L-shaped pipe 21 away from the second cylinder 2. A cable feeding component is arranged on one side of the second cylinder 2. The cable feeding component includes a slide rail 13 fixedly connected to the upper end of the first rectangular plate 11. A first cylinder 14 is slidably arranged on the upper end of the slide rail 13. A plurality of rectangular holes 141 are arranged on the outer side of the first cylinder 14. First rectangular strips 142 are respectively rotatably connected in the rectangular holes 141. First cylindrical blocks 1421 are fixedly connected to the ends of the first rectangular strips 142.

[0032] Specifically, after the cable stranding is completed, a rubber protective sleeve with a protective function is usually wrapped outside. In the prior art, when wrapping the cable, the end of the cable is first pulled out, passed through the middle of the wrapping device, and then the melted rubber fluid is discharged into the wrapping device to contact the cable. Subsequently, the cable is pulled out so that the rubber fluid is wrapped outside the cable. Since the temperature of the rubber fluid is relatively high, the temperature in the middle of the wrapping device will be relatively high. After processing a roll of cable, it is necessary to replace the cable for processing. Generally, the cable needs to be manually pulled out and passed through the outside of the wrapping device. Since the device temperature is relatively high, workers generally wear gloves to pick up the cable and pass it through the device, which poses a certain safety hazard. When using the present invention, the end of the cable is passed through the middle of the first cylinder 14, and then the first rectangular strip 142 is driven to rotate into the first cylinder 14 simultaneously in the rectangular hole 141. The first rectangular strip 142 drives the first cylindrical block 1421 to contact the outside of the cable. A rubber layer is provided on the outside of the first cylindrical block 1421 to prevent excessive extrusion of the cable. After clamping the cable, the first cylinder 14 is then driven to move the cable in the middle towards the second cylinder 2 until the first cylinder 14 is inserted into the middle of the second cylinder 2. Then, the first rectangular strip 142 is driven to drive the first cylindrical block 1421 away from the outside of the cable. Subsequently, the first cylinder 14 is slid out from the middle of the second cylinder 2, and the cable is left in the middle of the second cylinder 2, eliminating the need to manually pull the cable through the middle of the second cylinder 2 and avoiding potential safety hazards.

[0033] As Figure 2 shown, a conical cylinder 144 is fixedly connected to one end of the first cylinder 14 away from the second cylinder 2. A first slider 1441 is fixedly connected to the lower end of the conical cylinder 144, and the first slider 1441 can slide on the slide rail 13.

[0034] Specifically, when processing the cable, the cable is passed into the first cylinder 14 through the conical cylinder 144. The diameter of the end of the conical cylinder 144 away from the first cylinder 14 is larger, facilitating the cable to enter the middle of the first cylinder 14 with a smaller diameter.

[0035] As Figure 4 shown, a second ring 146 is fixedly connected to the outside of one end of the first cylinder 14 through a first rectangular block 145. Hypotenuse blocks 1461 respectively penetrate through the second ring 146 in a sliding manner. The hypotenuse blocks 1461 are respectively in contact with the corresponding first rectangular strips 142. A hypotenuse ring 147 is slidably connected to the outside of the second ring 146. One hypotenuse side of several hypotenuse blocks 1461 can slide along one hypotenuse side of the hypotenuse ring 147. A second slider 1471 is fixedly connected to the lower end of the hypotenuse ring 147, and the second slider 1471 can slide on the upper end of the slide rail 13.

[0036] Specifically, after passing the cable through the middle of the first cylinder 14, then drive the second slider 1471 to drive the bevel ring 147 to slide towards the second cylinder 2 side. The bevel ring 147 slides along the bevel of the bevel block 1461, driving the bevel block 1461 to slide into the second ring 146 simultaneously. The bevel block 1461 squeezes the first rectangular strip 142 inward, causing the first rectangular strip 142 to drive the first cylindrical block 1421 to squeeze the cable inward to clamp the cable. Then drive the first cylinder 14 to move the cable in the middle to the middle of the second cylinder 2 for wrapping.

[0037] As Figure 2 shown, a damper is installed between the first slider 1441 and the slide rail 13.

[0038] Specifically, when driving the second slider 1471 to drive the bevel ring 147 to slide outside the second ring 146, causing the bevel ring 147 to drive the bevel block 1461 to squeeze the first rectangular strip 142 and the cable, since a damper is installed between the first slider 1441 and the slide rail 13, the friction between the first slider 1441 and the slide rail 13 increases. When the second slider 1471 drives the bevel ring 147 to slide along the bevel block 1461, the first slider 1441 remains stationary. When the bevel block 1461 completely slides into the second ring 146, continue to drive the second slider 1471 to slide towards the second cylinder 2 side. At this time, drive the first slider 1441 to slide towards the second cylinder 2 side through the conical cylinder 144, and then the cable can be sent to the middle of the second cylinder 2.

[0039] As Figure 2 shown, a first ring 143 is fixedly connected to one end of the first cylinder 14 close to the second cylinder 2.

[0040] Specifically, after processing the cable for a period of time, a part of the rubber fluid will remain in the middle of the second cylinder 2. The remaining rubber fluid has a different temperature from the just heated rubber fluid. The temperature of the remaining rubber fluid becomes lower, resulting in poor fluidity and inability to wrap the cable well. When using the present invention, when driving the first cylinder 14 to slide into the second cylinder 2, the first cylinder 14 drives the first ring 143 to slide towards the middle of the second cylinder 2. The first ring 143 can slide along the inner wall of the middle of the second cylinder 2, and the remaining rubber fluid inside the second cylinder 2 can be scraped off, and new rubber fluid can be re-injected for wrapping.

[0041] As Figure 5 shown, two opposite semi-circular plates 22 are respectively fixedly connected by U-shaped strips 23. The lower ends of the U-shaped strips 23 are respectively fixedly connected with second rectangular plates 231. The opposite sides of the two second rectangular plates 231 are respectively fixedly connected with second rectangular strips 232. Both sides of the fixed block 24 are respectively fixedly connected with third rectangular strips 233. The second rectangular strips 232 can respectively slide inside the two ends of the third rectangular strips 233.

[0042] Specifically, after the cable is fed into the middle of the second cylinder 2, the second rectangular strips 232 on both sides are driven to slide into the third rectangular strip 233 at the same time. The second rectangular strips 232 drive the U-shaped strips 23 on both sides to slide towards the middle. The U-shaped strips 23 drive the semi-circular plates 22 on both sides to approach the middle simultaneously until the cable in the middle is clamped. The circular holes 221 provided in the middle of the two semi-circular plates 22 on the side away from the first cylinder 14 are larger than the circular holes 221 provided in the middle of the two semi-circular plates 22 on the side close to the first cylinder 14, which is convenient for the rubber fluid to be extruded after wrapping around the cable.

[0043] As Figures 6-7 shown, a cooling assembly is provided on the side of the second cylinder 2 away from the first cylinder 14. The cooling assembly includes a rectangular frame 3 fixedly connected to the upper end of the workbench 1. Third rectangular plates 31 are respectively fixedly connected to the lower ends of both sides of the rectangular frame 3. A second L-shaped pipe 32 penetrates through the upper end of the rectangular frame 3. A water tank 33 is fixedly connected to one end of the second L-shaped pipe 32 away from the rectangular frame 3. A circular ring pipe 321 is fixedly connected to one end of the second L-shaped pipe 32 close to the rectangular frame 3. The circular ring pipe 321 is located in the middle of the rectangular frame 3. A plurality of spray nozzles 322 are fixedly connected to the periphery of the middle of the circular ring pipe 321.

[0044] Specifically, when the cable is wrapped with rubber fluid, since the rubber fluid has a high temperature and is prone to deformation, it needs to be cooled and shaped. When using the present invention, the wrapped cable is passed through the middle of the circular ring pipe 321. Subsequently, the water pump installed inside the water tank 33 is started, and the water inside the water tank 33 is discharged into the circular ring pipe 321 through the second L-shaped pipe 32 and then sprayed out by the spray nozzles 322 to cool the cable in the middle. The sprayed water flows into the lower end of the rectangular frame 3 after contacting the outer side of the cable.

[0045] As Figure 8 shown, a cable pulling assembly is provided on the side of the rectangular frame 3 away from the second cylinder 2. The cable pulling assembly includes a third cylinder 4 fixedly connected to the workbench 1 through a second support bar 44. A third circular ring 43 is rotatably connected to the outer side of the third cylinder 4. A fourth rectangular strip 41 slidably penetrates through the edge of the third cylinder 4. Cylindrical strips 411 are respectively fixedly connected to one side of the fourth rectangular strip 41. Arc-shaped holes 431 are respectively provided at the edge of the third circular ring 43. The cylindrical strips 411 can respectively slide in the corresponding arc-shaped holes 431. A plurality of first arc-shaped strips 42 are provided in the middle of the third cylinder 4. The first arc-shaped strips 42 are respectively fixedly connected to the corresponding fourth rectangular strips 41. Second arc-shaped strips 421 are respectively slidably connected to the opposite sides of the plurality of first arc-shaped strips 42.

[0046] Specifically, when pulling out the completed cable for cooling, since the rubber fluid temperature on the outer side of the cable is relatively high, there are certain safety hazards in manually pulling it out. When using the present invention, drive the second arc-shaped strip 421 to slide towards the second cylinder 2, so that the second arc-shaped strip 421 passes through the circular ring tube 321 until it slides to the end of the cable. Then drive the third circular ring 43 to rotate to drive the cylindrical strip 411 to slide in the arc-shaped hole 431. The cylindrical strip 411 drives the fourth rectangular strip 41 to slide into the third cylinder 4 simultaneously. The fourth rectangular strip 41 drives the second arc-shaped strip 421 to slide towards the middle simultaneously through the first arc-shaped strip 42, so that the second arc-shaped strip 421 clamps the end of the cable. Then drive the second arc-shaped strip 421 to slide away from the second cylinder 2 on one side of the first arc-shaped strip 42, drive the cable to pass through the middle of the circular ring tube 321 and cool it, and then manually pull out the cooled cable to reduce safety hazards.

[0047] As Figure 8 shown, several of the second arc-shaped strips 421 are respectively rotatably connected with several arc-shaped runners 422.

[0048] Specifically, when the second arc-shaped strip 421 clamps the cable and drives the second arc-shaped strip 421 to slide away from the second cylinder 2 on one side of the first arc-shaped strip 42, the arc-shaped runners 422 rotate along one side of the first arc-shaped strip 42, so that several arc-shaped runners 422 rotate simultaneously. The rotation of the arc-shaped runners 422 drives the cable clamped in the middle to move away from the second cylinder 2. When the second arc-shaped strip 421 completely slides into the first arc-shaped strip 42, the end of the cable can extend out of one end of the first arc-shaped strip 42, facilitating the subsequent pulling of the cable. Embodiment 2

[0049] As Figure 2 、 Figure 8 shown, compared with Embodiment 1, another implementation manner of the present invention is: transmission components are respectively arranged on both sides of the upper end of the workbench 1. The transmission components include two first support strips 151 fixedly connected to the upper end of the workbench 1, and two extrusion runners 15 are rotatably connected between the two first support strips 151.

[0050] Specifically, first place the end of the cable between the two extrusion runners 15 close to the first cylinder 14, then process and cool the cable by wrapping it. Then pull out the end of the cable and feed it between the two extrusion runners 15 close to the third cylinder 4 to convey the cable for continuous processing.

[0051] Working principle: During processing, first place the end of the cable between the two extrusion rollers 15 on the side close to the first cylinder 14. Then, pass the cable through the conical cylinder 144 into the interior of the first cylinder 14. After passing the cable through and placing it in the middle of the first cylinder 14, then drive the second slider 1471 to drive the bevel ring 147 to slide towards the second cylinder 2. The bevel ring 147 slides along the bevel of the bevel block 1461, driving the bevel block 1461 to slide into the second ring 146 at the same time. The bevel block 1461 squeezes the first rectangular bar 142 inward, causing the first rectangular bar 142 to drive the first cylindrical block 1421 to squeeze the cable inward at the same time to clamp the cable. Since a damper is installed between the first slider 1441 and the slide rail 13, the friction between the first slider 1441 and the slide rail 13 is increased. When the second slider 1471 drives the bevel ring 147 to slide along the bevel block 1461, the first slider 1441 remains stationary. When the bevel block 1461 completely slides into the second ring 146, continue to drive the second slider 1471 to slide towards the second cylinder 2. At this time, drive the first slider 1441 to slide towards the second cylinder 2 through the conical cylinder 144. Then, the cable can be sent to the middle of the second cylinder 2. The first cylinder 14 drives the cable into the middle of the second cylinder 2. Then, drive the first rectangular bar 142 to drive the first cylindrical block 1421 away from the outer side of the cable. Then, drive the first cylinder 14 to slide out of the middle of the second cylinder 2, leaving the cable in the middle of the second cylinder 2;

[0052] After sending the cable into the middle of the second cylinder 2, drive the second rectangular bars 232 on both sides to slide into the third rectangular bar 233 at the same time. The second rectangular bars 232 drive the U-shaped bars 23 on both sides to slide towards the middle. The U-shaped bars 23 drive the semi-circular plates 22 on both sides to approach the middle at the same time until the cable in the middle is clamped. The round holes 221 provided in the middle of the two semi-circular plates 22 on the side away from the first cylinder 14 are larger than the round holes 221 provided in the middle of the two semi-circular plates 22 on the side close to the first cylinder 14, which is convenient for the rubber fluid to be extruded after wrapping around the outer side of the cable;

[0053] Subsequently, drive the spiral heater 211 to heat the rubber. The rubber flows from the first L-shaped pipe 21 into the second cylinder 2, contacts the cable, and wraps around the outside of the cable. Subsequently, drive the second arc-shaped strip 421 to slide towards the second cylinder 2, so that the second arc-shaped strip 421 passes through the circular ring pipe 321 until it slides to the end of the cable. Subsequently, drive the third circular ring 43 to rotate, driving the cylindrical strip 411 to slide in the arc-shaped hole 431. The cylindrical strip 411 drives the fourth rectangular strip 41 to slide into the third cylinder 4 simultaneously. The fourth rectangular strip 41 drives the second arc-shaped strip 421 to slide towards the middle simultaneously through the first arc-shaped strip 42, so that the second arc-shaped strip 421 clamps the end of the cable. Subsequently, drive the second arc-shaped strip 421 to slide away from the second cylinder 2 on one side of the first arc-shaped strip 42, driving the cable to pass through the middle of the circular ring pipe 321. Subsequently, start the water pump installed inside the water tank 33, drain the water inside the water tank 33 into the circular ring pipe 321 through the second L-shaped pipe 32, and then spray it out from the nozzle 322 to cool the cable in the middle.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
