Description

Technical Field

[0001] This invention belongs to the field of wire and cable production technology, and specifically discloses a sheath drying and forming device for wire and cable production. Background Technology

[0002] During the extrusion process, the extruded material covers the surface of the wire core under the action of the extruder head. In order to achieve the cooling and molding of the insulation sheath of the wire and cable, the insulation sheath covering the surface of the wire core needs to enter the cooling water tank for cooling treatment. After the wire and cable leave the cooling water tank, the insulation sheath of the cable will have the cooling liquid of the cooling water tank on it. At this time, the cooling liquid on the insulation sheath needs to be dried. In traditional wire and cable insulation sheath drying equipment, workers need to use traction equipment to separate the insulation sheath from the cooling water tank during the drying process. Then, an air jet structure is used to separate water droplets from the insulation sheath. After the water droplets are separated, the insulation sheath is wiped by a wiping structure. During this process, the wiping structure can absorb the remaining water on the insulation sheath. However, existing insulating sleeve drying and molding devices do not have a good water flow guiding structure. When the wiping sponge in the wiping structure absorbs a lot of water, the staff needs to drain the water from the wiping sponge. This means that the wiping structure cannot continuously dry the insulating sleeve, which causes great inconvenience during the drying process.

[0003] To address this issue, we propose a sheath drying and forming device for wire and cable production, which solves the problem that the wiping structure in the insulation sheath drying and forming device cannot continuously dry the insulation sheath. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a sheath drying and forming device for wire and cable production, so as to solve the problem that the wiping structure in the insulation sheath drying and forming device cannot continuously dry the insulation sheath.

[0005] To achieve the above objectives, the present invention provides a drying and forming device for sheathing of wires and cables, comprising a connecting housing and a wiping sponge rotating on the connecting housing. The wiping sponge has an overlapping notch, and a cable is overlapped on the wiping sponge at the overlapping notch. A transmission rod is rotatably connected to the connecting housing, and a threaded joint is fixedly connected to the upper end of the transmission rod. The wiping sponge is fitted onto the threaded joint. A water seepage plate is fixedly connected to the bottom of the wiping sponge, and a guide plate abuts against the bottom surface of the water seepage plate. A rotating disk is fixedly connected to the bottom surface of the guide plate, and water guide pipes are fixedly connected to the bottom surface of the rotating disk at equal intervals. The guide plate has a through hole, a guide notch, and a water guide section. The rotating disk has a water guide hole, which communicates with the inner cavity of the water guide pipe. The drain end of the water guide pipe is inserted into the inner cavity of the connecting housing.

[0006] In the above technical solution, an annular shell is further fixedly connected to the connecting housing, the inner cavity of the annular shell is connected to the inner cavity of the connecting housing, and the annular shell is rotatably connected to the rotating disk.

[0007] In the above technical solution, the threaded joint is further provided with a pressure plate, which abuts against the wiping sponge. The lower part of the transmission rod is fixedly connected with a blade, which is distributed in the inner cavity of the connecting housing.

[0008] In the above technical solution, a drainage structure is further fixedly connected to the lower part of the connecting shell, the inner cavity of the drainage structure is connected to the inner cavity of the connecting shell, and the discharge end of the drainage structure is inclined downward.

[0009] In the above technical solution, a connecting bracket and a transmission motor are fixedly connected to the connecting housing. The output end of the transmission motor passes through the connecting housing and is fixedly connected to the transmission rod. The transmission rod and the threaded joint are coaxially distributed.

[0010] In the above technical solution, the flow guide notch is distributed on the flow guide plate near the outer edge, the water guide part is distributed on the flow guide plate near the inner edge, and the inner cavity of the through hole is connected to the flow guide notch and the inner cavity of the water guide part.

[0011] In the above technical solution, the portion of the guide plate near the through hole, the guide notch, and the water guide part is lower than other parts of the guide plate, the portion of the rotating plate near the water guide hole is lower than other parts of the rotating plate, and a convex ring is fixedly connected to the outer edge of the rotating plate.

[0012] In the above technical solution, both the guide plate and the rotating plate are provided with mounting holes, and the guide plate and the rotating plate are fixed to the threaded joint through the mounting holes, with the guide plate embedded in the rotating plate.

[0013] In the above technical solution, the bottom surface of the seepage plate is a planar structure, the bottom surface of the seepage plate is fixed to the guide plate, and the diameter of the seepage plate is smaller than the diameter of the rotating plate.

[0014] In the above technical solution, a connecting pipe is further fixedly connected to the annular shell at an incline, and an air jet structure is fixedly connected to the upper end of the connecting pipe. The air jet structure includes a through ring fixedly connected to the connecting pipe. A connecting chamfer is provided on the inner wall of the through ring away from the connecting shell. A first liquid suction hole is provided on the side of the through ring away from the connecting shell, and a second liquid suction hole is provided on the connecting chamfer.

[0015] Compared with the prior art, the present invention has the following beneficial effects: When the drive motor in the sheath drying and forming device drives the wiping sponge on the threaded joint to rotate through the drive rod, the wiping sponge can quickly transport the cable to the cable. At the same time, the wiping sponge can also wipe the water off the cable, thus achieving the drying treatment of the cable after cooling.

[0016] 2. After the wiping sponge in the sheath drying and forming device absorbs a large amount of water, the water will enter the interior of the rotating disk under the action of gravity. During this process, the guide plate can guide the water flowing out of the wiping sponge, so that the water flowing out of the wiping sponge can be quickly discharged through the water pipe.

[0017] 3. When the drive motor in the sheath drying and molding device drives the wiping sponge on the threaded joint to rotate through the drive rod, the water inside the rotating disk will be discharged through the through holes at different positions on the rotating disk, which can realize that the water on the rotating disk can quickly enter the interior of the connecting shell through the water guide pipe.

[0018] 4. When the drive motor in the sheath drying and forming device drives the wiping sponge on the threaded joint to rotate through the drive rod, the paddle will drive the air inside the connecting shell to be discharged through the drainage structure. During this process, the air discharged from the connecting shell will drive the water inside the connecting shell to be squeezed out through the drainage structure. The top of the connecting shell is in a negative pressure state, and the inside of the water guide pipe is also in a negative pressure state, thereby realizing the rapid discharge of water on the rotating plate.

[0019] 5. When the upper part of the connecting shell in the sheath drying and forming device is under negative pressure, the inside of the connecting pipe and the through ring is also under negative pressure. Since the cable passes through the inside of the through ring, when the surface of the cable contains water, the through ring can absorb the water on the surface of the cable through the first and second suction holes, which can avoid absorbing too much water on the wiping sponge.

[0022] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0024] In practical use, the existing insulating sleeve drying and forming device does not have a good water flow guiding structure. When the wiping sponge in the wiping structure absorbs a lot of water, the staff needs to drain the water from the wiping sponge. This causes the wiping structure to be unable to continuously dry the insulating sleeve, resulting in great inconvenience during the drying process. Therefore, the following structure is proposed to solve the above problems.

[0025] Example 1: Please refer to Figure 1-8 As shown, the present invention provides a technical solution: This invention relates to a drying and molding device for sheathing in the production of wires and cables, comprising a connecting housing 5 and a wiping sponge 6 rotating on the connecting housing 5. The wiping sponge 6 has an overlap notch 69, on which a cable 2 overlaps. A transmission rod 72 is rotatably connected to the connecting housing 5, and a threaded joint 7 is fixedly connected to the upper end of the transmission rod 72. The wiping sponge 6 is sleeved on the threaded joint 7. A water seepage plate 610 is fixedly connected to the bottom of the wiping sponge 6. A guide plate 63 abuts against the bottom surface of the water seepage plate 610. A rotating plate 64 is fixedly connected to the bottom surface of the guide plate 63. Water guide pipes 62 are fixedly connected to the bottom surface of the rotating plate 64 at equal intervals. The guide plate 63 has a through hole 66, a guide notch 67, and a water guide part 68. The rotating plate 64 has a water guide hole 65, which communicates with the inner cavity of the water guide pipe 62. The drain end of the water guide pipe 62 is inserted into the inner cavity of the connecting housing 5. It should be noted that there are two sets of through holes 66. One set is located on the guide plate 63 near the threaded joint 7, and the other set is located on the guide plate 63 near the edge. The water guide hole 65 is located on the rotating plate 64, directly below the through hole 66. The overlapping notch 69 is an annular notch structure opened on the wiping sponge 6. The depth of the overlapping notch 69 is half the diameter of the cable 2. When the cable 2 abuts against the overlapping notch 69, the wiping sponge 6 can absorb the water on the cable 2 through the overlapping notch 69. In actual use, cable 2 is attached to the wiping sponge 6. When the transmission rod 72 drives the wiping sponge 6 to rotate through the threaded joint 7, the wiping sponge 6 can drive one end of cable 2. At the same time, the wiping sponge 6 can absorb the water on cable 2, thereby enabling cable 2 to be quickly transmitted under the drive of the wiping sponge 6. When the water absorbed by the wiping sponge 6 reaches saturation, the water will seep into the seepage plate 610 under the action of gravity. Then the seepage plate 610 will transmit the water to the rotating plate 64. During this process, the guide plate 63 can guide the water falling from the seepage plate 610, so that the water can quickly enter the interior of the guide pipe 62 through the water guide hole 65, and then enter the interior of the connecting shell 5 through the guide pipe 62. It should be noted that the seepage plate 610 can be a steel wire woven disc structure. In this document, its function is to drive the wiping sponge 6 to be placed on the guide plate 63, and at the same time realize the water on the wiping sponge 6 to be transferred to the rotating plate 64 through the seepage plate 610.

[0026] Example 2: Please refer to Figure 2-8 As shown, based on Embodiment 1, the present invention provides a technical solution. Unlike Embodiment 1, the wiping sponge 6 in this embodiment can quickly drain water into the interior of the connecting housing 5, thereby enabling the wiping sponge 6 to continuously absorb water from the cable 2.

[0027] An annular shell 4 is fixedly connected to the connecting housing 5. The inner cavity of the annular shell 4 is connected to the inner cavity of the connecting housing 5. The annular shell 4 and the rotating disk 64 are rotatably connected. When the rotating disk 64 rotates on the annular shell 4, the wiping sponge 6 can rotate stably on the threaded joint 7, thereby enabling the wiping sponge 6 to transmit power to the cable 2.

[0028] A pressure plate 71 is threadedly connected to the threaded connector 7, and the pressure plate 71 abuts against the wiping sponge 6. A blade 73 is fixedly connected to the lower part of the transmission rod 72, and the blade 73 is distributed in the inner cavity of the connecting housing 5. The pressure plate 71 and the threaded joint 7 are connected by threads, which makes it easy for the staff to remove the pressure plate 71 from the threaded joint 7. Since the blade 73 is fixedly connected to the transmission rod 72, when the transmission rod 72 rotates on the connecting housing 5, the transmission rod 72 can drive the blade 73 to rotate inside the connecting housing 5.

[0029] A drainage structure 51 is fixedly connected to the lower part of the connecting housing 5. The inner cavity of the drainage structure 51 is connected to the inner cavity of the connecting housing 5, and the discharge end of the drainage structure 51 is inclined downward. The drainage structure 51 can discharge the water inside the housing 5 to the outside. The operator can connect the discharge end of the drainage structure 51 to the external equipment, which can realize the diversion of the water discharged by the drainage structure 51 to the external equipment.

[0030] A connecting bracket 52 and a drive motor 8 are fixedly connected to the connecting housing 5. The output end of the drive motor 8 passes through the connecting housing 5 and is fixedly connected to the drive rod 72. The drive rod 72 and the threaded joint 7 are coaxially distributed. The output end of the drive motor 8 can drive the drive rod 72 to rotate on the connecting housing 5, which can stably drive the blade 73 to rotate on the connecting housing 5, thereby enabling the blade 73 to drive the air inside the connecting housing 5 to be discharged through the drainage structure 51.

[0031] The flow guide opening 67 is distributed on the flow guide plate 63 near the outer edge, and the water guide part 68 is distributed on the flow guide plate 63 near the inner edge. The inner cavity of the through hole 66 is connected to the inner cavity of the flow guide opening 67 and the water guide part 68. The guide opening 67 and the water guide part 68 can transfer the water inside the rotating disk 64 to the through hole 66. At the same time, the guide disk 63 can transfer the water through the seepage disk 610 to the guide opening 67 and the water guide part 68, thereby realizing the rapid discharge of water inside the wiping sponge 6 and the rapid absorption of water on the cable 2 by the wiping sponge 6.

[0032] The portion of the guide plate 63 near the through hole 66, the guide notch 67 and the water guide part 68 is lower than the other parts of the guide plate 63. The portion of the rotating plate 64 near the water guide hole 65 is lower than the other parts of the rotating plate 64. A convex ring 611 is fixedly connected to the outer edge of the rotating plate 64. When the water discharged from the seepage plate 610 falls onto the guide plate 63, the guide plate 63 can transport the water discharged from the wiping sponge 6 to the guide opening 67 and the water guide part 68, thereby realizing the rapid discharge of water inside the wiping sponge 6. Since the rotating plate 64 is fixedly connected with the convex ring 611, the convex ring 611 can block the water inside the rotating plate 64, thereby realizing the rapid transportation of water inside the rotating plate 64 to the water guide pipe 62.

[0033] Both the guide plate 63 and the rotating plate 64 are provided with mounting holes 61. The guide plate 63 and the rotating plate 64 are fixed to the threaded joint 7 through the mounting holes 61, and the guide plate 63 is embedded in the rotating plate 64. When the guide plate 63 and the rotating plate 64 are fixed on the threaded joint 7 through the mounting hole 61, the transmission rod 72 can drive the guide plate 63 and the rotating plate 64 to rotate through the threaded joint 7. Since the guide plate 63 can play the role of guiding the flow, when the rotating plate 64 and the guide plate 63 rotate synchronously, excess water will rotate on the guide plate 63 and the rotating plate 64, which can realize the simultaneous drainage of multiple through holes 66, improve the drainage efficiency, and thus realize the rapid transfer of water inside the rotating plate 64 to the water pipe 62 through the water guide hole 65.

[0034] The bottom surface of the seepage plate 610 is a planar structure. The bottom surface of the seepage plate 610 is fixed to the guide plate 63. The diameter of the seepage plate 610 is smaller than the diameter of the rotating plate 64. By setting the diameter of the seepage plate 610 to be smaller than the diameter of the rotating plate 64, the water discharged from the seepage plate 610 can be collected by the rotating plate 64. Since the bottom surface of the seepage plate 610 and the guide plate 63 are fixed, the water discharged from the seepage plate 610 can be guided by the guide plate 63, so that the guide plate 63 can quickly transfer the water to the rotating plate 64, and then the water can be guided to the interior of the connecting shell 5 through the water guide pipe 62.

[0035] Example 3: Please refer to Figure 1 , 6 As shown, based on Embodiment 1, the present invention provides a technical solution. Unlike Embodiment 1, the through-ring 12 in this embodiment can extract water from the cable 2, thereby preventing excessive water from the cable 2 from being absorbed by the wiping sponge 6 and improving the water absorption effect of the wiping sponge 6 on the cable 2.

[0036] A connecting pipe 3 is fixedly connected to the annular shell 4 at an incline. An air jet structure 1 is fixedly connected to the upper end of the connecting pipe 3. The air jet structure 1 includes a through ring 12 fixedly connected to the connecting pipe 3. A connecting chamfer 13 is provided on the inner wall of the through ring 12 away from the connecting shell 5. A first liquid suction hole 11 is provided on the side of the through ring 12 away from the connecting shell 5. A second liquid suction hole 14 is provided on the connecting chamfer 13. In actual use, the output end of the drive motor 8 can drive the blade 73 to rotate inside the connecting housing 5 through the transmission rod 72. At this time, the air disturbed by the blade 73 can drive the water inside the connecting housing 5 to be squeezed out from the inside of the drainage structure 51. The upper part of the connecting housing 5 is in a negative pressure state. At this time, the water inside the water guide pipe 62 and the connecting pipe 3 can quickly enter the inside of the connecting housing 5, thereby improving the water absorption effect of the connecting housing 5. It should be noted that the distance between the first suction hole 11 and the second suction hole 14 and the cable 2 is set according to the actual use and is not within the protection scope of this document. When the inside of the connecting tube 3 is under negative pressure, the water on the cable 2 will be transferred to the inside of the through ring 12 through the first suction hole 11 and the second suction hole 14. Then the water inside the through ring 12 will be discharged into the inside of the connecting housing 5 through the connecting tube 3, thereby realizing the rapid collection of water on the cable 2 by the through ring 12 and avoiding the collection of too much water by the wiping sponge 6. Working principle: In actual use, the user first passes the cable 2 through the inside of the through-ring 12 and overlaps the cable 2 on the wiping sponge 6 in the overlap notch 69. When the output shaft of the drive motor 8 drives the wiping sponge 6 on the threaded joint 7 to rotate through the drive rod 72, the wiping sponge 6 can support and transmit the cable 2, and can also absorb the water on the cable 2. In order to ensure that the water on the cable 2 is evenly absorbed by the wiping sponge 6, the operator needs to set the device on both sides of the cable 2, and the cable 2 passes between the two devices. When the wiping sponge 6 absorbs the water on the cable 2, the water discharged from the seepage plate 610 is guided by the guide plate 63, so that the guide plate 63 quickly transfers the water to the rotating plate 64, and then the water is guided to the inside of the connecting housing 5 through the water pipe 62. The output end of the drive motor 8 can drive the blade 73 to rotate inside the connecting housing 5 through the drive rod 72. At this time, the air disturbed by the blade 73 can drive the water inside the connecting housing 5 to be squeezed out from the inside of the drainage structure 51. At the same time, the upper part of the connecting housing 5 is in a negative pressure state, and the water inside the water pipe 62 and the connecting pipe 3 can quickly enter the inside of the connecting housing 5. When the inside of the connecting pipe 3 is in a negative pressure state, the water on the cable 2 will be transferred to the inside of the through ring 12 through the first suction hole 11 and the second suction hole 14. Then the water inside the through ring 12 will be discharged into the inside of the connecting housing 5 through the connecting pipe 3, thereby realizing the rapid collection of water on the cable 2 by the through ring 12 and avoiding the collection of too much water by the wiping sponge 6.

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