Description

Technical Field

[0001] This invention relates to the field of cable processing technology, and specifically to a cable processing apparatus and processing method. Background Technology

[0002] Cables are crucial carriers of electrical energy or signals, widely used in power, communications, transportation, and other fields. During cable production, the extruded plastic layer is at a high temperature and requires rapid cooling and shaping in a cooling tank to ensure structural stability and performance standards. Currently, the industry commonly uses water immersion for cable cooling; the cable enters a tank filled with cooling water directly after exiting the extruder, achieving cooling through heat exchange.

[0003] Existing cooling tanks have certain drawbacks in practical applications. For example, when cables are first extruded, the surface plastic layer is not fully cured and is relatively soft. During the process of entering the cooling tank, it needs to pass through the guide structure at the tank entrance, such as the threading hole and guide roller. Since the inlet guide components of traditional cooling tanks are mostly made of rigid materials and lack buffer protection between them and the cable, when the cable deviates slightly due to fluctuations in production speed or changes in tension, its surface is very prone to friction and collision with the edge of the guide components, resulting in scratches, dents, or even damage to the plastic layer. In addition, some cooling tanks use seals such as sponges or rubber rings at the inlet to prevent cooling water from overflowing, but the compression and friction of the seals further exacerbate the risk of damage to the cable surface.

[0004] Scratches on the cable surface not only affect the product's appearance quality but may also weaken the protective performance of the insulation layer, leading to safety hazards such as leakage and short circuits during subsequent use, and reducing the product qualification rate. Furthermore, scratched cables require repair or disposal, increasing production costs and labor time. Summary of the Invention

[0005] The purpose of this invention is to provide a cable processing device and processing method to solve the problem in the prior art that when the cable enters the cooling tank from the base equipment, the cable surface is not solidified and it is easy to cause damage to the cable surface if it scrapes against the entrance of the cooling tank.

An electronic level gauge is provided in the water tank.

[0010] A further technical solution is that the outer wall of the first rod is provided with a first sliding section, a second sliding section and a third sliding section in a stepped manner, with the diameters of the first sliding section, the second sliding section and the third sliding section decreasing sequentially.

A fourth iron ring is fixedly disposed on the third sliding section at a position away from the second sliding section.

[0011] A further technical solution is that the mounting block is provided with a large air hole and a small air hole that are connected to the bottom of the second elastic hole, and a one-way valve is provided on the large air hole that allows one-way passage from the second elastic hole to the outside of the mounting block.

[0012] A further technical solution is that a heat dissipation box is set on the lower side of the water tank, and air inlets and outlets that connect to the inside of the heat dissipation box are set on opposite sides of the heat dissipation box. A fan is installed at the air inlet. A heat dissipation coil is set between the air inlet and the air outlet of the heat dissipation box. Both ends of the heat dissipation coil are connected to the water tank. A third water pump is set inside the water tank, and the pumping end of the third water pump is connected to one end of the heat dissipation coil.

[0013] A further technical solution is that the outer wall of the heat sink is surrounded by an air inlet with a mounting ring, the fan is installed inside the mounting ring, the outer wall of the mounting ring is provided with a through hole, a humidifying nozzle is installed in the through hole, the humidifying nozzle is connected to an external water supply device, and temperature sensors are installed in both the water tank and the water trough.

The bottom of the first water receiving trough and the second water receiving trough are both connected to the first chamber. The bottom of the third water receiving trough is connected to the second chamber.

[0015] A further technical solution is that an air vent is installed at the outlet end of the water tank, and an air hole is provided inside the air vent that runs through both ends. One end of the air hole is aligned with the outlet end of the water tank, and a high-speed fan is installed on both sides of the air hole.

[0016] The second technical solution adopted in this invention is:

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting a pre-cooling section, it can be directly connected to a position close to the extruder. When the cable comes out of the extruder, it will first pass through the cooling hole. Cooling water will flow out from the water outlets on both sides of the cooling hole and spray onto the cable, so that the outer insulation layer of the cable will be quickly cured. In this way, when the cable enters the water tank through the first notch, the cable insulation layer will not be damaged due to friction with the first notch; 2. The lower hole wall of the cooling hole is inclined, which allows the water in the cooling hole to flow to the first water receiving tank by means of the inclined hole wall.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0030] Figures 1 to 9 The image shows an embodiment of the present invention.

[0031] Example 1:

[0032] A cable processing device includes a water tank 1 and a water trough 2 installed on the upper side of the water tank 1. The inlet end of the water trough 2 is provided with a first notch 3. The inlet end of the water trough 2 is provided with a first water receiving trough 4 below the first notch 3. The bottom of the first water receiving trough 4 is connected to the water tank 1. A first water pump 5 is provided in the water tank 1. The outlet end of the first water pump 5 is connected to the bottom of the water trough 2. A pre-cooling part 6 is installed at the opening of the first water receiving trough 4 away from the first notch 3. A cooling hole 7 penetrating both ends is provided in the pre-cooling part 6. The cooling hole 7 is aligned with the first notch 3. Water outlet holes 8 are provided on the hole walls on both sides of the cooling hole 7. A second water pump 9 is installed in the water tank 1. The outlet end of the second water pump 9 is connected to the water outlet hole 8. The lower hole wall of the cooling hole 7 slopes upward from one end near the first water receiving trough 4 to the other end. By setting up the pre-cooling section 6, it can be directly connected near the extruder. After the cable comes out of the extruder, it will first pass through the cooling hole 7. The cooling hole 7 can be set larger to avoid the cable contacting the hole wall. Cooling water will flow out from the water outlet holes 8 on both sides of the cooling hole 7 and spray it onto the cable, so that the outer insulation layer of the cable can be cured quickly. In this way, when the cable enters the water tank 2 through the first notch 3, the cable insulation layer will not be damaged due to friction with the first notch 3. The lower hole wall of the cooling hole 7 is inclined so that the water in the cooling hole 7 can flow to the first water receiving tank 4 by means of the inclined hole wall.

[0033] A water-blocking block 10 is installed at the inlet end of the water tank 2 at the first notch 3. Clamping pieces 11 are spaced apart on the front side of the water-blocking block 10. The upper ends of the clamping pieces 11 are connected to the upper ends of the water-blocking block 10 via connecting blocks 12. The clamping pieces 11 are placed inside the water tank 2, and the water-blocking block 10 is placed outside the water tank 2. A second notch 13 aligned with the first notch 3 is provided on the clamping pieces 11. An installation groove 14 is provided on the lower side of the water-blocking block 10, and a third notch 15 communicating with the installation groove 14 is provided on the front side of the water-blocking block 10. The widths of both the second notch 13 and the third notch 15 are greater than the width of the first notch 3. A first rod 16 and a second rod 17 are horizontally arranged in a mounting groove 14 within a notch 3. One end of the first rod 16 is mounted on the groove wall of the mounting groove 14 on the side opposite to the third notch 15. The other end of the first rod 16 is provided with a first elastic hole 18. One end of the second rod 17 is slidably placed in the first elastic hole 18 and is connected to the bottom of the first elastic hole 18 through a first spring 19. A sealing plate 20 is installed on the end of the first rod 16 facing the first notch 3. The width of the sealing plate 20 is smaller than that of the third notch 15 and larger than that of the first notch 3. When the cable enters the water tank 2 through the first notch 3 for cooling, it needs to be completely submerged in the water in the tank 2 to improve the cooling effect. Therefore, the water level in the tank 2 must be higher than the lower part of the first notch 3 by a certain height, which is generally more than twice the diameter of the cable. However, such a water level in the tank 2 will cause a large amount of water to flow out of the first notch 3. This requires increasing the power of the first water pump 5 to replenish the water in the water tank 1 into the tank 2. This will consume a lot of electrical energy if the water pump is used for a long time. Based on this, this application uses a water-blocking block 10 to block part of the first notch 3 at the position of the first notch 3 to reduce the outflow velocity of the water from the first notch 3. The water-blocking block 10 is fixed to the tank wall of the water tank 2 with the help of a clamp 11. The clamp 11 can be provided with threaded holes that pass through both sides, and locking nuts are installed in the threaded holes to prevent the water-blocking block 10 from moving during use. Furthermore, this detachable structure facilitates the placement of the traction rope into the first notch 3 during cable and traction rope installation. After the traction rope and cable are connected, the water-blocking block 10 is then installed at the position of the first notch 3. In use, the water-blocking block 10, through the cooperation of the first rod 16 and the second rod 17, uses the elasticity of the first spring 19 to cause the sealing plate 20 to adhere to the outer wall of the water tank 2, blocking part of the first notch 3. A gap is left between the lower side of the sealing plate 20 and the lower side of the first notch 3 for the cable to pass through. Because the diameter of each cable is different, the size of the gap will also be adjusted accordingly. To accommodate these adjustments, the first water pump 5 is a power-adjustable type, which allows control over the flow rate of water delivered by the first water pump 5 to the water tank 2.When the water level in the water tank 2 rises, the water pressure also increases, and the thrust exerted by the water pressure on the sealing plate 20 also increases. This pushes the sealing plate 20 to separate from the outer wall of the water tank 2 by compressing the first spring 19. This increases the flow of water discharged from the first notch 3 in the water tank 2, thus preventing the water level in the water tank 2 from rising too quickly and overflowing. The first spring 19 is selected from a type with low elasticity, which can generate sufficient thrust even under low water pressure. The specific elasticity varies depending on the specific type and size of the water tank 2. Generally, multiple sealing plates 20, along with their corresponding first rod 16, second rod 17, and first spring 19, are installed from top to bottom. The use of multiple sealing plates 20 enables gradient drainage, thereby improving drainage efficiency and preventing the water level in the water tank 2 from dropping too quickly.

[0034] The rear side of the water-blocking block 10 is provided with a mounting hole 21 that communicates with the mounting groove 14. A mounting block 22 is installed in the mounting hole 21. A second elastic hole 23 is provided on the side of the mounting block 22 facing the third notch 15. The end of the first rod 16 away from the second rod 17 is slidably placed in the second elastic hole 23 and is connected to the bottom of the second elastic hole 23 through a second spring 24. An annular electromagnet 25 is provided around the second elastic hole 23 on the mounting block 22, and a first iron ring plate 26 is provided around the outer wall of the first rod 16 outside the second elastic hole 23. An electronic level gauge 27 is provided in the water tank 2. By providing the electronic level gauge 27, the water level in the water tank 2 can be monitored in real time. Since the water level in the tank 2 is generally not very deep, the thrust generated on the sealing plate 20 is limited. When the power regulation function of the first water pump 5 malfunctions and the water level in the tank 2 rises sharply, relying solely on water pressure to push the sealing plate 20 to separate it from the outer wall of the tank 2 for drainage is insufficient to quickly discharge a large volume of water. Therefore, when the electronic level gauge 27 detects a rapid increase in water level, energizing the annular electromagnet 25 generates a magnetic attraction force on the first iron ring 26, causing the first rod 16 to move a distance toward the bottom of the second elastic hole 23 and compressing the second spring 24. This allows the sealing plate 20 to instantly separate from the outer wall of the tank 2, achieving rapid drainage. Furthermore, with the help of the sealing plate 20, the water flow impacting the sealing plate 20 during drainage will flow downwards, preventing the water from flowing outwards in an arc and splashing out of the first water receiving tank 4. The first iron ring piece 26 can be made of two half-rings spliced ​​together, which makes it easy to install the first iron ring piece 26 onto the first rod body 16. The splice of the two half-rings can be made by plugging or gluing.

[0035] The outer wall of the first rod 16 is provided with a stepped first sliding section 28, a second sliding section 29, and a third sliding section 30, with the diameters of the first sliding section 28, the second sliding section 29, and the third sliding section 30 decreasing sequentially. A first iron ring plate 26 is slidably disposed on the first sliding section 28. A first magnet 31 is disposed on the first sliding section 28 at a position away from the second sliding section 29. A second iron ring plate 34 is slidably disposed on the second sliding section 29. A second magnet 32 ​​is disposed on the second sliding section 29 at a position close to the first sliding section 28. A third iron ring plate 35 is installed on the third sliding section 30. A third magnet 33 is disposed on the third sliding section 30 at a position close to the second sliding section 29. A fourth iron ring plate 36 is fixedly disposed on the third sliding section 30 at a position away from the second sliding section 29. The first iron ring 26, the second iron ring 34, the third iron ring 35, and the fourth iron ring 36 are positioned via the first sliding section 28, the second sliding section 29, and the third sliding section 30. When the annular electromagnet 25 is energized, it sequentially attracts the first iron ring 26, the second iron ring 34, the third iron ring 35, and the fourth iron ring 36. This causes the first rod 16 to compress the second spring 24 by a significant distance, thereby increasing the gap between the sealing plate 20 and the outer wall of the water tank 2 sufficiently. When the annular electromagnet 25 is de-energized, the first rod 16, pushed by the second spring 24, will return the first iron ring 26, the second iron ring 34, and the third iron ring 35 to their original positions on the first sliding section 28, the second sliding section 29, and the third sliding section 30. By using the first magnet 31, the second magnet 32, and the third magnet 33, the positions of the first iron ring 26, the second iron ring 34, and the third iron ring 35 can be effectively fixed.

[0036] The mounting block 22 is provided with a large air hole 37 and a small air hole 38 that communicate with the bottom of the second elastic hole 23. A one-way valve 39 is provided on the large air hole 37, which allows one-way flow from the second elastic hole 23 to the outside of the mounting block 22. By providing the large air hole 37 and the small air hole 38, when the first rod 16 compresses the second spring 24, the air in the second elastic hole 23 is quickly expelled, allowing the first rod 16 to move quickly within the second elastic hole 23. When the annular electromagnet 25 is de-energized, and the first rod 16 moves away from the bottom of the second elastic hole 23 under the push of the second spring 24, the one-way valve 39 allows air to enter only through the small air hole 38. This reduces the moving speed of the first rod 16, thus preventing the first iron ring plate 26, the second iron ring plate 34, and the third iron ring plate 35 from failing to return to their correct positions due to excessively rapid reset of the first rod 16. Guide surfaces are provided at the connection points of the first sliding segment 28 and the second sliding segment 29, and at the connection points of the second sliding segment 29 and the third sliding segment 30, to allow the first sliding segment 28 and the second sliding segment 29 to pass through the circular holes in the centers of the first iron ring plate 26 and the second iron ring plate 34 during reset. The one-way valve 39 can be a simple silicone duckbill valve, which can be glued to the outer end of the large air hole 37.

[0037] Example 2:

[0038] Based on Embodiment 1, a heat dissipation box 40 is provided on the lower side of the water tank 1. Air inlets and outlets 41, communicating with the interior of the heat dissipation box 40, are respectively provided on opposite sides of the heat dissipation box 40. A fan 42 is installed at the air inlet. A heat dissipation coil 43 is provided between the air inlet and outlet 41 of the heat dissipation box 40. Both ends of the heat dissipation coil 43 are connected to the water tank 1. A third water pump 44 is provided inside the water tank 1, and the pumping end of the third water pump 44 is connected to one end of the heat dissipation coil 43. After long-term circulation with the water in the water tank 2, the water in the water tank 1 will gradually heat up. This application, by using the heat dissipation coil 43, the third water pump 44, and the fan 42 in combination, can effectively reduce the water temperature in the water tank 1. The large contact area of ​​the heat dissipation coil 43, in contact with the high-speed flowing air, reduces the temperature of the water flowing through the heat dissipation coil 43.

[0039] A mounting ring 45 surrounds the air inlet on the outer wall of the heat sink 40. The fan 42 is mounted inside the mounting ring 45. A through-hole 46 is provided on the outer wall of the mounting ring 45, and a humidifying nozzle 47 is installed inside the through-hole 46. The humidifying nozzle 47 is connected to an external water supply device. Temperature sensors 48 are installed in both the water tank 2 and the water container 1. By using the humidifying nozzle 47, water mist is added to the high-speed airflow from the fan 42. This water mist, upon contact with the heat sink 43, quickly evaporates, rapidly reducing the temperature of the heat sink 43 and thus improving heat dissipation efficiency. The temperature sensors 48 effectively monitor the water temperature in the water container 1 and the water tank 2, allowing for adjustments to the power of the fan 42 and the spray efficiency of the humidifying nozzle 47 based on the water temperature.

[0040] The water tank 2 is divided into two partitions: a first partition 49 and a second partition 50. The first partition 49 and the second partition 50 have a fourth notch 51 and a fifth notch 52, respectively. A third partition 53 is positioned between the first partition 49 and the second partition 50. A second water receiving trough 54 is formed between the first partition 49 and the third partition 53. A third water receiving trough 55 is formed between the second partition 50 and the third partition 53. The upper end of the third partition 53 is flush with the lower side of the fourth notch 51. The water tank 1 has a fourth partition 56 at the position corresponding to the third partition 53, dividing the water tank 1 into a first chamber and a second chamber. The bottoms of the first water receiving trough 4 and the second water receiving trough 54 are connected to the first chamber, and the bottom of the third water receiving trough 55 is connected to the second chamber. This divides the water tank 2 into two cooling zones with different water temperatures. The first and second chambers supply water to the two cooling zones respectively. Corresponding heat dissipation coils 43 are also installed below the first and second chambers for water temperature control. The same method can be used to divide the water into more temperature zones, thus achieving stepped cooling. Water-blocking blocks 10 can be installed at both the fourth gap 51 and the fifth gap 52.

[0041] Example 3:

[0042] Based on the aforementioned embodiment, an air duct 57 is installed at the outlet end of the water tank 2. An air vent 58, penetrating both ends, is provided within the air duct 57. One end of the air vent 58 is aligned with the outlet end of the water tank 2, and high-speed fans 59 are installed on both opposite sides of the air vent 58. After the cable has cooled down in the water tank 2, it passes through the air vent 58, where a high-speed airflow quickly dries the water stains on the cable surface. This prevents water stains from affecting subsequent processes such as coding or other procedures.

[0043] Example 4:

[0044] A cable processing method, using a cable processing apparatus as described in the foregoing embodiments, includes the following steps: Step S1, drawing a metal conductor to a preset diameter using a wire drawing machine and annealing it to eliminate internal stress; Step S2, uniformly coating the conductor surface with insulating material using an extruder to obtain a cable; Step S3, passing the cable sequentially through a pre-cooling section 6 and a water tank 2 for cooling; Step S4, testing the cable insulation performance using a high-voltage tester, and winding it into a coil after it passes the test.
