Description

Technical Field

[0001] The present invention relates to the technical field of cable processing, and in particular to a cable threading device and process for wire and cable processing. Background Art

[0002] In cable production, to protect and insulate the inner core, an insulating layer is wrapped around the core using a cable threading device. The insulating layer material is first added to the extruder's hopper. Inside the extruder, the rotating screw and heated barrel gradually plasticize the material into a molten state. The plasticized insulating layer passes through a mold within the die head and is formed into the desired insulation dimensions. The formed insulation layer then cools and solidifies. During the cooling process, the insulating layer material transforms from a molten state to a solid state, forming a solid insulation layer that is then evenly coated around the cable (conductor or core).

[0003] In the aforementioned prior art, fans or water sprays are usually used to cool the insulation layer. However, fans have a poor cooling effect, while water sprays can easily cause the incompletely formed insulation layer to absorb moisture, resulting in a decrease in insulation performance.

DETAILED DESCRIPTION

[0036] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0037] See also Figures 1 to 9The present invention provides a cable threading device for wire and cable processing, comprising a base 1, an insulating layer 2, a wire core 3 and a cooling assembly, wherein the cooling assembly comprises four cooling support plates 4, a plurality of cooling balls 5, four annular cooling pipes 6 and four cooling units, wherein the cooling unit comprises a pump body 7, a cooling trough 8, a plurality of cooling baffles 9, a plurality of heat absorbing plates 10, a plurality of heat dissipation mechanisms and two first fans 11, wherein the heat absorbing plate 10 has a flow hole 12, and the heat dissipation mechanism comprises a heat absorbing column 13 and a plurality of heat sinks 14, wherein the cooling assembly further comprises an air-cooling unit, an annular rotating unit and an insulating layer 2 supporting unit, wherein the air-cooling unit comprises an air-cooling support frame 15 and a plurality of second fans 16, wherein the annular rotating unit comprises a rotating support frame 17, four A rotary drive mechanism, a gear ring 18, an annular support plate 19, multiple cooling lifting components 20 and multiple pressure sensors 21, the rotary drive mechanism includes a rotary drive component 22 and a gear 23, the insulating layer 2 abutting unit includes a abutting support frame 24 and four abutting units, the abutting unit includes a fixed plate 25, abutting support plate 26, multiple abutting balls 27, multiple telescopic rods 28, a slider 29, a slide groove 30, a first electromagnet 31, a second electromagnet 32 ​​and a linkage mechanism, the linkage mechanism includes a card block 33, two springs 34, a third electromagnet 35, a fourth electromagnet 36, an infrared transmitter 37 and an infrared receiver 38, the abutting support plate 26 has a groove 39, and the cooling support plate 4 has a card slot 40.

[0038] The insulating layer 2 is sleeved on the outside of the wire core 3, and the insulating layer 2 is located above the base 1. The four cooling support plates 4 are sequentially distributed around the outside of the insulating layer 2. The multiple cooling balls 5 are sequentially matched with the internal gaps of the corresponding cooling support plates 4. The four annular cooling pipes 6 are respectively arranged inside the corresponding cooling support plates 4, and the four cooling units are respectively arranged on one side of the corresponding cooling support plates 4. First, the insulating layer 2 is output from the extruder and placed above the base 1; then the cooling support plate 4 moves so that the cooling balls 5 are in close contact with the insulating layer 2; at the same time, the cooling unit cools the cooling water; the cooling water flows inside the cooling support plate 4 through the annular cooling channel, cooling the cooling balls 5; at this time, the cooling balls 5 are in contact with the insulating layer 2, achieving the effect of cooling and shaping; finally, the insulating layer 2 is continuously transported and sleeved on the outside of the wire core 3.

[0039] Secondly, the heat absorbing plate 10 has a circulation hole 12, the pump body 7 and the cooling groove 8 are both arranged on one side of the cooling support plate 4, the water inlet end of the pump body 7 is connected to one end of the annular cooling pipe 6, the water outlet end of the pump body 7 is connected to one side of the cooling groove 8, and the other side of the cooling groove 8 is connected to the other end of the annular cooling pipe 6, a plurality of the cooling baffles 9 are distributed in sequence inside the cooling groove 8, a plurality of the heat absorbing plates 10 are distributed in sequence between two adjacent cooling baffles 9, a plurality of the heat dissipation mechanisms are arranged on the cooling groove 8 in sequence, and the two first fans 11 are fixedly connected to the cooling groove 8 and are located above the cooling groove 8. When cooling, the pump body 7 starts to draw cooling water from one end of the annular cooling pipe 6, and then flows into the cooling groove 8. The multiple cooling baffles 9 form a circulation channel for cooling water inside the cooling groove 8. The cooling water flows along the circulation channel and contacts the multiple heat-absorbing plates 10 and the heat dissipation mechanism at the same time, quickly absorbing the heat of the cooling water, and the first fan 11 is also started to further dissipate heat from the cooling water. Finally, the cooling water is discharged from the cooling groove 8 and re-enters the annular cooling pipe 6 to cool the cooling ball 5. In addition, the cooling ball 5 and the cooling support plate 4 are made of heat-conducting material, which facilitates heat transfer and helps to improve the cooling effect of the insulating layer 2; at the same time, the circulation hole 12 provided on the heat-absorbing plate 10 can increase the contact area with the cooling water and increase the cooling water flow rate to avoid slow flow of the cooling water due to the setting of the heat-absorbing plate 10.

[0040] At the same time, the heat-absorbing column 13 is fixedly connected to the cooling trough 8 and is located on the inner bottom wall of the cooling trough 8. The other end of the heat-absorbing column 13 extends through the cooling trough 8, and a plurality of heat sinks 14 are sequentially distributed on the other end of the heat-absorbing column 13. When the cooling water flows, it continuously contacts the heat-absorbing column 13. The heat-absorbing column 13 absorbs the heat of the cooling water and then heats up, dissipating the heat to the heat sink 14. At this time, the first fan 11 is activated to blow air to the heat-absorbing column 13 and the heat sink 14 to cool them down. This circulation greatly improves the cooling speed and cooling effect of the cooling water.

[0041] In addition, the air cooling unit is arranged above the base 1, the annular rotation unit is arranged on one side of the air cooling, and the insulating layer 2 supporting unit is arranged on the side of the annular rotation unit away from the air cooling unit. The air cooling unit is mainly used to perform preliminary cooling on the insulating layer 2 when the insulating layer 2 is just output from the extruder, so that its appearance is stable and deformation is avoided when it contacts the cooling ball 5 later. The annular rotation unit is used to drive the cold zone support plate to rotate in an annular manner, thereby driving multiple cooling balls 5 to rotate in an annular manner around the insulating layer 2. At the same time, the cooling balls 5 are matched with the internal clearance of the cooling support plate 4, so that they can rotate freely in multiple directions to avoid friction damage to the insulating layer 2. In this way, the insulating layer 2 is cooled in all directions and shaped so that it can be subsequently installed on the outside of the wire core 3. The insulating layer 2 supporting unit is used to fix the position of the shaped insulating layer 2 to avoid shaking and deviation when docking with the wire core 3, so that it can be smoothly installed on the outside of the wire core 3.

[0042] Then, the air-cooling support frame 15 is fixedly connected to the base 1 and is mounted outside the insulating layer 2. A plurality of second fans 16 are sequentially distributed inside the air-cooling support frame 15. The air-cooling support frame 15 supports the second fans 16. When the second fans 16 are turned on, they initially cool the insulating layer 2 and initially shape it to prevent deformation caused by the cooling balls 5 due to its poor hardness.

[0043] Again, the rotating support frame 17 is arranged on one side of the air-cooled support frame 15 and is sleeved on the outside of the insulating layer 2. The four rotating drive mechanisms are arranged on the rotating support frame 17 in sequence. The annular support plate 19 is rotatably connected to the rotating support frame 17. The gear ring 18 is fixedly connected to the annular support plate 19 and is distributed on the outside of the annular support plate 19. Multiple cooling lifting components 20 are arranged on the inner wall of the annular support plate 19 in sequence. The output ends of multiple cooling lifting components 20 are fixedly connected to the corresponding cooling support plates 4. The pressure sensor 21 is arranged at the connection between the output end of the cooling lifting component 20 and the cooling support plate 4. The cooling lifting component 20 is a self-locking cylinder. When cooling is required: the output end of the cooling lifting component 20 extends to drive the cooling support plate 4 to move, and adjusts the position of the cooling ball 5 so that it contacts and fits with the outer wall of the insulating layer 2 for cooling operation. At the same time, the pressure sensor 21 detects the pressure value and sets the preset pressure value to avoid excessive contact pressure causing the insulating layer 2 to be deformed; then the rotating support frame 17 supports the rotating drive mechanism, and the rotating drive mechanism is started, driving the annular support plate 19 to rotate, thereby driving the cooling support plate 4 to rotate in a circle outside the insulating layer 2, and then making the cooling ball 5 move in a circle outside the insulating layer 2 for all-round cooling.

[0044] Furthermore, the rotary drive component 22 is disposed on one side of the rotary support frame 17. The output end of the rotary drive component 22 is fixedly connected to the gear 23, which meshes with the gear ring 18. The rotary drive component 22 is a motor. When the rotary drive component 22 is started, it drives the gear 23 to rotate, meshing with the gear ring 18, and driving the annular support plate 19 to rotate on the rotary support frame 17, thereby rotating the cooling support plate 4 and the cooling balls 5.

[0045] Furthermore, the supporting support frame 24 is arranged above the base 1, and the four supporting units are arranged on one side of the supporting support frame 24 in sequence; the fixed plate 25 is arranged on one side of the supporting support frame 24, and both ends of the multiple telescopic rods 28 are respectively fixedly connected to the fixed plate 25 and the supporting support plate 26, and the slide groove 30 is arranged on one side of the supporting support frame 24, the first electromagnet 31 is arranged at one end of the slider 29, and the second electromagnet 32 ​​is arranged inside the slide groove 30, one end of the slider 29 is slidably connected to the slide groove 30, and the other end of the slider 29 is fixedly connected to the supporting plate 26, and the linkage mechanism is arranged on the supporting support plate 26 and the cooling support plate 4, and the multiple supporting balls 27 are matched with the internal clearance of the supporting plate 26 in sequence. The supporting frame 24 supports the fixed plate 25, and the fixed plate 25 supports the telescopic rod 28, and the telescopic rod 28 can avoid shaking when the supporting plate 26 moves up and down; when supporting is needed: first, before the cooling support plate 4 moves, the supporting plate 26 is docked with the cooling support plate 4 through the linkage mechanism, and after the cooling support plate 4 moves down, the cooling ball 5 is located in a suitable position through the action of the pressure sensor 21. At the same time, due to the action of the linkage mechanism, the cooling support plate 4 drives the supporting plate 26 to move along when it moves, thereby making the supporting ball 27 on the supporting plate 26 and the cooling ball 5 located at the same horizontal line, avoiding excessive supporting pressure, and at the same time, the cooling lifting component 20 can also be used to drive the cooling ball 5 at one time. The movement of the supporting plate 4 and the abutting supporting plate 26 reduces the use of driving equipment, reduces the cost of use, and simplifies the structure; in addition, when the abutting supporting plate 26 slides up and down, the slider 29 slides in the slide groove 30, and when the abutting ball 27 is in the appropriate position, the first electromagnet 31 and the second electromagnet 32 ​​are energized to attract each other, and the position can be fixed at this time, and then the linkage mechanism is closed, so that the abutting supporting plate 26 and the cooling supporting plate 4 are disconnected, and then the abutting supporting plate 26 only needs to remain in position in subsequent use, and plays the role of limiting the connection between the insulating layer 2 and the wire core 3, and the cooling support plate 4 is disconnected from the abutting supporting plate 26, so it can rotate freely in a circle without affecting the abutting supporting plate 26.

[0046] Finally, the abutting support plate 26 has a groove 39, the cooling support plate 4 has a card slot 40, one end of the card block 33 is adapted to the card slot 40, and the other end of the card block 33 is slidingly connected to the groove 39. The two ends of the two springs 34 are respectively movably connected to the other end of the card block 33 and the inner wall of the groove 39. The third electromagnet 35 is fixedly connected to the other end of the card block 33 and is located between the two springs 34. The fourth electromagnet 36 is arranged on the inner wall of the groove 39. The infrared transmitter 37 is arranged on the inner wall of the card slot 40, and the infrared receiver 38 is arranged at one end of the card block 33. When the supporting support plate 26 and the cooling support plate 4 need to be linked, the cooling lifting component 20 is first started to drive the cooling support plate 4 to rise and fall and adjust its position. At the same time, the annular support plate 19 rotates until the infrared rays emitted by the infrared transmitter 37 are received by the infrared receiver 38, indicating that the card slot 40 and the card block 33 are aligned. At this time, the third electromagnet 35 and the fourth electromagnet 36 are powered off and no longer attract each other. Then, through the action of the spring 34, the card block 33 pops out and enters the card slot 40, completing the connection between the supporting support plate 26 and the cooling support plate 4.

[0047] When using the cable threading equipment for wire and cable processing of the present embodiment, the insulating layer 2 is first output from the extruder and placed on top of the base 1; then when cooling is required: the output end of the cooling lifting component 20 extends to drive the cooling support plate 4 to move, and adjust the position of the cooling ball 5 so that it contacts and fits with the outer wall of the insulating layer 2 for cooling operation, while the pressure sensor 21 detects the pressure value and sets the preset pressure value to avoid excessive contact pressure causing the insulating layer 2 to be deformed; when cooling begins, the pump body 7 starts to pump cooling water from the annular cooling pipe 6 One end is drawn out and then flows into the cooling trough 8. The multiple cooling baffles 9 form a circulation channel for cooling water inside the cooling trough 8. The cooling water flows along the circulation channel and contacts the multiple heat absorbing plates 10 and the heat dissipation mechanism at the same time, quickly absorbing the heat of the cooling water. The first fan 11 is also started to further dissipate the heat of the cooling water. Finally, the cooling water is discharged from the cooling trough 8 and re-enters the annular cooling pipe 6 to cool the cooling ball 5. At this time, the cooling ball 5 contacts the insulating layer 2 to achieve the effect of cooling and shaping. At the same time, the insulating layer 2 is continuously transported and sleeved on the outside of the wire core 3.

[0048] Through the above-mentioned structural setting, the cooling ball 5 is continuously cooled by the annular cooling pipe 6, and then the cooling ball 5 contacts the continuously moving and transported insulating layer 2, and takes away the heat of the insulating layer 2 through the principle of heat exchange, thereby significantly improving the cooling effect compared with air cooling, and eliminating the need to use spray water, thereby avoiding the risk of the insulating layer 2 absorbing moisture and causing damage or performance degradation.

[0050] S1: The insulating layer 2 is output from the extruder and placed on the base 1;
