Description

Technical Field

[0001] The invention belongs to the technical field of cable processing equipment, in particular to a cable threading equipment. Background Art

[0002] Cable is a rope-like cable made of several or several groups of wires twisted together. Each group of wires is insulated from each other and often twisted around a center. The entire outer layer is covered with a highly insulating covering. In the cable processing process, after the cable is wound, it is usually wrapped with a protective rubber sheath. In the processing process, an extruder is usually used to produce and process it in the form of wrapping.

[0003] A patent with publication number CN117672639B discloses a cable threading device for cable processing. The cable threading device for cable processing passes the cable through the base hole, the annular threading block and the center of the centering module in sequence, and squeezes the molten rubber into the annular flow channel through a rubber extruder, so that the annular flow channel is filled with molten rubber fluid, and continues to move with the cable. The annular flow channel is circular as a whole, so that the rubber fluid can be evenly wrapped on the outer surface of the cable, thereby facilitating the cable threading worker.

[0004] In the above-mentioned prior art, when wrapping the insulation layer of the cable, it is necessary to wrap the hot-melt rubber fluid on the outside of the cable and pull out the cable. During the process, when a roll of cable is processed, it is necessary to replace the cable for processing, and the cable end needs to be placed in the middle of the rubber extruder again. Since the temperature of the hot-melt rubber is high, the temperature inside the rubber extruder will be high. When replacing the cable, the cable is generally picked up by a person wearing gloves, and then the cable is placed in the middle of the rubber extruder, which poses certain safety hazards.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0022] like Figure 1-Figure 3As shown, a cable threading device described in 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, and clamping components are respectively provided at both ends of the second cylinder 2, the clamping components include semicircular plates 22 respectively slidably connected on both sides of one end of the second cylinder 2, and circular holes 221 are respectively provided in the middle of the semicircular plates 22, a first L-shaped tube 21 is fixedly connected to the upper end of the second cylinder 2, and a spiral heating machine 211 is fixedly connected to the end of the first L-shaped tube 21 away from the second cylinder 2, and a cable feeding assembly is provided on one side of the second cylinder 2, and the cable feeding assembly includes a slide rail 13 fixedly connected to the upper end of the first rectangular plate 11, and a first cylinder 14 is slidably arranged on the upper end of the slide rail 13, and a plurality of rectangular holes 141 are arranged on the outer side of the first cylinder 14, and first rectangular bars 142 are respectively rotatably connected in the rectangular holes 141, and first cylindrical blocks 1421 are fixedly connected to the ends of the first rectangular bars 142.

[0023] Specifically, after the cable is twisted, it is usually necessary to wrap it with a rubber protective sheath with a protective function. When wrapping the cable in the prior art, the end of the cable is first pulled out and passed through the middle of the wrapping device, and then the melted rubber fluid is discharged into the wrapping device to contact the cable, and then the cable is pulled out so that the rubber fluid is wrapped around the outside of 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, the cable needs to be replaced for processing. Generally, the cable needs to be manually pulled out and passed through the outside of the wrapping device. Since the temperature of the device is relatively high, workers generally wear gloves to take the cable and pass it through the device, which poses certain safety hazards. When using the present invention, the cable end is passed through the first cylinder 14, and then drive the first rectangular bar 142 to rotate towards the inside of the first cylinder 14 in the rectangular hole 141 at the same time, the first rectangular bar 142 drives the first cylindrical block 1421 to contact the outside of the cable, and a rubber layer is provided on the outside of the first cylindrical block 1421 to prevent excessive squeezing of the cable. After clamping the cable, the first cylinder 14 is then driven to drive the middle part of the cable to move toward the side close to the second cylinder 2 until the first cylinder 14 is inserted into the middle of the second cylinder 2, and then drive the first rectangular bar 142 to drive the first cylindrical block 1421 away from the outside of the cable, and then drive the first cylinder 14 to slide out from the middle of the second cylinder 2, leaving the cable in the middle of the second cylinder 2, without manually pulling the cable through the middle of the second cylinder 2, to avoid safety hazards.

[0024] like Figure 2 As shown, a conical cylinder 144 is fixedly connected to one end of the first cylinder 14 away from the second cylinder 2 , and a first sliding block 1441 is fixedly connected to the lower end of the conical cylinder 144 . The first sliding block 1441 can slide on the slide rail 13 .

[0025] Specifically, when processing the cable, the cable is passed through the conical cylinder 144 into the first cylinder 14 . The conical cylinder 144 has a larger diameter at one end away from the first cylinder 14 , which facilitates the cable to enter the middle part of the first cylinder 14 with a smaller diameter.

[0026] like Figure 4 As shown, a second circular ring 146 is fixedly connected to the outer side of one end of the first cylinder 14 through a first rectangular block 145, and bevel blocks 1461 are respectively slidably penetrated around the second circular ring 146, and the bevel blocks 1461 are respectively in contact with the corresponding first rectangular strips 142, and a bevel circular ring 147 is slidably connected to the outer side of the second circular ring 146, and one side of the beveled edge of several beveled edge blocks 1461 can slide along one side of the beveled edge of the beveled edge ring 147, and a second slider 1471 is fixedly connected to the lower end of the bevel circular ring 147, and the second slider 1471 can slide on the upper end of the slide rail 13.

[0027] Specifically, after the cable is passed through and placed into the middle of the first cylinder 14, the second slider 1471 is then driven to drive the beveled ring 147 to slide toward the side close to the second cylinder 2, and the beveled ring 147 slides along the bevel of the beveled block 1461, driving the beveled block 1461 to slide toward the inside of the second ring 146 at the same time, and the beveled block 1461 squeezes the first rectangular bar 142 inward, so that the first rectangular bar 142 drives the first cylindrical block 1421 to squeeze the cable inward at the same time to clamp the cable, and then the first cylinder 14 is driven to drive the cable in the middle to move to the middle of the second cylinder 2 for wrapping.

[0028] like Figure 2 As shown, a damper is installed between the first sliding block 1441 and the sliding rail 13.

[0029] Specifically, when the second slider 1471 is driven to drive the hypotenuse ring 147 to slide on the outside of the second ring 146, so that the hypotenuse ring 147 drives the hypotenuse block 1461 to squeeze the first rectangular bar 142 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, and when the second slider 1471 drives the hypotenuse ring 147 to slide along the hypotenuse block 1461, the first slider 1441 remains stationary. When the hypotenuse block 1461 completely slides into the inside of the second ring 146, it continues to drive the second slider 1471 to slide toward the side close to the second cylinder 2. At this time, the first slider 1441 is driven to slide toward the side close to the second cylinder 2 through the conical cylinder 144, and then the cable can be delivered to the middle of the second cylinder 2.

[0030] like Figure 2 As shown, a first ring 143 is fixedly connected to one end of the first cylinder 14 close to the second cylinder 2 .

[0031] Specifically, after the cable is processed for a period of time, a portion of rubber fluid will remain in the middle of the second cylinder 2. The temperature of the residual rubber fluid is different from that of the rubber fluid that has just been heated. The temperature of the residual rubber fluid becomes lower, resulting in poor fluidity and failure to wrap the cable well. When using the present invention, when driving the first cylinder 14 to slide inside the second cylinder 2, the first cylinder 14 drives the first ring 143 to slide toward 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, so that the residual rubber fluid inside the second cylinder 2 can be scraped off, and new rubber fluid can be re-injected for wrapping.

[0032] like Figure 5 As shown, the two relatively semicircular plates 22 are fixedly connected by U-shaped bars 23 respectively, the lower ends of the U-shaped bars 23 are fixedly connected to second rectangular plates 231 respectively, the opposite sides of the two second rectangular plates 231 are fixedly connected to second rectangular bars 232 respectively, the two sides of the fixed block 24 are fixedly connected to third rectangular bars 233 respectively, and the second rectangular bars 232 can slide inside the two ends of the third rectangular bars 233 respectively.

[0033] Specifically, after the cable is fed into the middle of the second cylinder 2, the second rectangular bars 232 on both sides are driven to slide toward the inside of 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 toward the middle, and the U-shaped bars 23 drive the semicircular plates 22 on both sides to approach the middle at the same time until the cable in the middle is clamped. The circular holes 221 provided in the middle of the two semicircular 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 semicircular plates 22 on the side close to the first cylinder 14, so that the rubber fluid is wrapped around the outside of the cable and then extruded.

[0034] like Figure 6-Figure 7 As shown, a cooling assembly is provided on the side of the second cylinder 2 away from the first cylinder 14, and the cooling assembly includes a rectangular frame 3 fixed to the upper end of the workbench 1, and third rectangular plates 31 are fixed to the lower ends of both sides of the rectangular frame 3 respectively. A second L-shaped tube 32 passes through the upper end of the rectangular frame 3, and a water tank 33 is fixed to the end of the second L-shaped tube 32 away from the rectangular frame 3. A circular tube 321 is fixed to the end of the second L-shaped tube 32 close to the rectangular frame 3. The circular tube 321 is located in the middle of the rectangular frame 3, and a plurality of nozzles 322 are fixed around the middle of the circular tube 321.

[0035] Specifically, after the outer side of the cable is wrapped with rubber fluid, the rubber fluid has a high temperature and is easy to deform, so it needs to be cooled and shaped. When using the present invention, the wrapped cable is passed through the middle of the annular tube 321, and then the water pump installed inside the water tank 33 is started to discharge the water inside the water tank 33 from the second L-shaped tube 32 to the annular tube 321, and then sprayed out by the nozzle 322 to cool the middle part of the cable. The sprayed water contacts the outside of the cable and flows into the lower end of the rectangular frame 3.

[0036] like Figure 8As shown, a cable pulling assembly is provided on the side of the rectangular frame 3 away from the second cylinder 2, and the cable pulling assembly includes a third cylinder 4 fixedly connected to the workbench 1 through a second support bar 44, a third ring 43 is rotatably connected to the outer side of the third cylinder 4, a fourth rectangular bar 41 is slidably penetrated through the edge of the third cylinder 4, a cylindrical bar 411 is fixedly connected to one side of the fourth rectangular bar 41, arc holes 431 are respectively provided on the edges of the third ring 43, and the cylindrical bars 411 can slide in the corresponding arc holes 431, and a plurality of first arc bars 42 are provided in the middle part of the third cylinder 4, the first arc bars 42 are respectively fixedly connected to the corresponding fourth rectangular bars 41, and the opposite sides of the plurality of first arc bars 42 are respectively slidably connected to second arc bars 421.

[0037] Specifically, when the wrapped cable is pulled out for cooling, due to the high temperature of the rubber fluid on the outside of the cable, manual pulling out has certain safety hazards. When using the present invention, the second arc strip 421 is driven to slide toward the side close to the second cylinder 2, so that the second arc strip 421 passes through the annular tube 321 until it slides to the end of the cable, and then the third ring 43 is driven to rotate to drive the cylindrical strip 411 to slide in the arc hole 431, and the cylindrical strip 411 drives the fourth rectangular strip 41 to slide toward the inside of the third cylinder 4 at the same time. The fourth rectangular strip 41 drives the second arc strip 421 to slide toward the middle at the same time through the first arc strip 42, so that the second arc strip 421 clamps the cable end, and then the second arc strip 421 is driven to slide on the side of the first arc strip 42 toward the side away from the second cylinder 2, driving the cable to pass through the middle of the annular tube 321 and cool down, and then the cooled cable is manually pulled out to reduce safety hazards.

[0038] like Figure 8 As shown, the middle parts of the plurality of second arc-shaped bars 421 are rotatably connected to a plurality of arc-shaped rotating wheels 422 .

[0039] Specifically, after the second arc bar 421 clamps the cable, the second arc bar 421 is driven to slide on the side of the first arc bar 42 toward the side away from the second cylinder 2, and the arc wheel 422 rotates along the side of the first arc bar 42, so that several arc wheels 422 rotate at the same time. The rotation of the arc wheel 422 simultaneously drives the cable clamped in the middle to move toward the side away from the second cylinder 2. When the second arc bar 421 completely slides into the inside of the first arc bar 42, the end of the cable can extend out of one end of the first arc bar 42, which is convenient for subsequent pulling of the cable. Embodiment 2

[0040] like Figure 2 , Figure 8 As shown, compared with Example 1, another embodiment of the present invention is: transmission components are respectively provided on both sides of the upper end of the workbench 1, and the transmission components include two first support bars 151 fixedly connected to the upper end of the workbench 1, and two extrusion wheels 15 are rotatably connected between the two first support bars 151.

[0041] Specifically, the cable end is first placed between the two extrusion wheels 15 close to the first cylinder 14, and then the cable is wrapped and cooled. Then, the cable end is pulled out and sent between the two extrusion wheels 15 close to the third cylinder 4, and the cable is conveyed and continuously processed.

[0042] Working principle: During processing, first put the cable end between the two extrusion wheels 15 near the first cylinder 14, then pass the cable through the conical cylinder 144 into the first cylinder 14, and after the cable is passed through the middle of the first cylinder 14, drive the second slider 1471 to drive the hypotenuse ring 147 to slide toward the side close to the second cylinder 2, and the hypotenuse ring 147 slides along the hypotenuse of the hypotenuse block 1461, driving the hypotenuse block 1461 to slide toward the inside of the second ring 146 at the same time, and the hypotenuse block 1461 squeezes the first rectangular strip 142 inwardly, so that the first rectangular strip 142 drives the first cylindrical block 1421 to squeeze the cable inwardly at the same time to clamp the cable. Since a damper is installed between the first slider 1441 and the slide rail 13, the first slider The friction between the block 1441 and the slide rail 13 increases. When the second slider 1471 drives the hypotenuse ring 147 to slide along the hypotenuse block 1461, the first slider 1441 remains stationary. When the hypotenuse block 1461 completely slides into the second ring 146, it continues to drive the second slider 1471 to slide toward the side close to the second cylinder 2. At this time, the first slider 1441 is driven to slide toward the side close to the second cylinder 2 through the conical cylinder 144, and 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, and then drives the first rectangular bar 142 to drive the first cylindrical block 1421 away from the outside of the cable, and then drives the first cylinder 14 to slide out from the middle of the second cylinder 2, leaving the cable in the middle of the second cylinder 2. 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 toward the inside of the third rectangular strip 233 at the same time, and the second rectangular strips 232 drive the U-shaped strips 23 on both sides to slide toward the middle, and the U-shaped strips 23 drive the semicircular plates 22 on both sides to approach the middle at the same time until the cable in the middle is clamped, and the circular holes 221 in the middle of the two semicircular plates 22 on the side away from the first cylinder 14 are larger than the circular holes 221 in the middle of the two semicircular plates 22 on the side close to the first cylinder 14, so that the rubber fluid is wrapped around the outside of the cable and then extruded; Then, the spiral heater 211 is driven to heat the rubber, and the rubber flows into the second cylinder 2 from the first L-shaped tube 21, contacts the cable and is wrapped around the outside of the cable. Then, the second arc strip 421 is driven to slide toward the side close to the second cylinder 2, so that the second arc strip 421 passes through the annular tube 321 until it slides to the end of the cable. Then, the third ring 43 is driven to rotate to drive the cylindrical strip 411 to slide in the arc hole 431. The cylindrical strip 411 drives the fourth rectangular strip 41 to slide toward the inside of the third cylinder 4 at the same time. The four rectangular bars 41 drive the second arc bar 421 to slide toward the middle at the same time through the first arc bar 42, so that the second arc bar 421 clamps the end of the cable, and then drives the second arc bar 421 to slide on the side of the first arc bar 42 away from the second cylinder 2, driving the cable to pass through the middle of the annular tube 321, and then starts the water pump installed inside the water tank 33 to discharge the water inside the water tank 33 from the second L-shaped tube 32 to the annular tube 321, and then sprays it out from the nozzle 322 to cool the cable in the middle.
