Description

Technical Field

[0001] This application relates to the field of cable conductor cleaning technology, and more particularly to a conductor surface cleaning device for cable manufacturing. Background Technology

[0002] Cables are carriers of electrical energy or signals, consisting of a metal conductor (such as copper or aluminum) as the core transmission medium, surrounded by insulation materials and a sheath. During manufacturing, contaminants such as residual grease from processing, wire drawing lubricants, metal oxides (such as Cu2O and Al2O3), and environmental dust on the conductor surface lead to three major problems: First, the oxide layer increases conductor resistance (measured >8%), causing transmission loss and localized overheating; second, oil contamination reduces the adhesion of the insulation layer, creating micropores (<0.1mm) during extrusion molding, inducing the risk of partial discharge breakdown; third, micron-sized metal debris (50-200μm) embeds into the insulation interface, causing electrochemical corrosion over long-term operation. Therefore, conductor cleaning is a key process for ensuring the conductivity, insulation integrity, and long-term reliability of cables, directly determining product lifespan.

[0003] Based on the above, the prior art patent document with publication number CN219648165U discloses a conductor cleaning device for cable manufacturing. In this device, the conductor of the cable being transported can be continuously cleaned by using two sets of wiping cotton in contact. The cleaning liquid inside the wiping cotton mounting cover slowly penetrates into the wiping cotton, which can enhance the cleaning effect of the wiping cotton on the cable conductor. This has certain positive significance. However, it also has certain drawbacks. For example, the wiping method using wiping cotton can only remove impurities with poor adhesion and easy to wipe off from the conductor surface. Some oxide layers and stubborn attached impurities cannot be cleaned.

[0004] Therefore, there is an urgent need to provide a device that can clean cable conductors in all directions. Summary of the Invention

[0019] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.

[0020] like Figure 1-14 As shown, a conductor surface cleaning device for cable manufacturing includes: A cylindrical wire-passing area is provided for the cable conductor 5 to pass through. The cable conductor 5 is always located in the wire-passing area during the cleaning process. The size of the wire-passing area should be larger than the diameter of the cable conductor 5. The wire-passing area has a certain length in the running direction of the cable conductor 5.

[0021] The operation of cable conductor 5 can be achieved through a winding reel.

[0022] Air distribution ring 2 is installed on the frame and located on the radial periphery of the line passing area. Air distribution ring 2 is mainly used to connect the air source. The gas in the air source enters the air distribution ring 2 through the pipe. The air distribution ring 2 evenly distributes the airflow into a ring and makes the airflow flow along a specific path.

[0023] A connecting arm can be installed on the air distribution ring 2, and the end of the connecting arm away from the air distribution ring 2 is connected to the frame.

[0024] A rotating ring 1 is rotatably mounted on an air distribution ring 2. Multiple air-blowing pipes 4 are spaced circumferentially on the rotating ring 1, with the outlets of the air-blowing pipes 4 pointing towards the axis of the rotating ring 1. The rotating ring 1 can rotate relative to the air distribution ring 2, causing the air-blowing pipes 4 to rotate relative to the cable conductor 5. This creates a spiral airflow on the outer peripheral surface of the cable conductor 5, effectively cleaning debris from its surface. The spiral airflow impacts the debris on the surface of the cable conductor 5 from different angles, increasing the removal rate. Furthermore, the impurities blown off by the spiral airflow move in one direction with the airflow, facilitating collection and preventing debris from flying around and causing secondary pollution.

[0025] The scraper 3 is rotatably mounted on the frame; the scraper 3 is equipped with a scraper 31; after being impacted by the spiral airflow in the air pipe 4, the cable conductor 5 is pre-cleaned; however, the impact of the airflow cannot blow away some stubborn debris, and the cable conductor 5 may also develop an oxide layer due to improper storage. The presence of the oxide layer will also affect the normal use of the cable conductor 5 in the future. Therefore, the scraper 3 is specially set up to treat the scratches, grooves or oxide layers in the cable conductor 5.

[0026] The scraper 31 is wrapped around the cable conductor 5. Through the continuous rotation of the scraper frame 3, the scraper 31 continuously scrapes and polishes the cable conductor 5 to remove the oxide layer on the cable conductor 5.

[0027] The scraping component 31 can be steel wool with a certain degree of flexibility, preferably with a strip structure.

[0028] The axes of the cable passage area, rotating ring 1, and scraper 3 coincide; radially: rotating ring 1 and air distribution ring 2 are located on the periphery of the cable passage area, that is, the cable conductor 5 runs in the central area of ​​rotating ring 1 and air distribution ring 2.

[0029] The air blowing pipe 4 is specifically set on the side of the rotating ring 1 facing away from the scraper 3. There are multiple air blowing pipes 4, which are arranged circumferentially. The air outlet 110 of the air blowing pipe 4 gradually moves towards the wire passing area and gradually comes into contact with the cable conductor 5.

[0030] By setting up a rotating feed ring and an air distribution ring 2, the debris on the cable conductor 5 will be blown off directly, and the air blowing pipe 4 can generate a spiral airflow, thereby more effectively removing the debris from the cable conductor 5; in addition, the scraping component 31 on the scraping frame 3 can scrape off the oxide layer on the cable conductor 5, thereby better cleaning the cable conductor 5 to meet the needs of further cleaning and use of the cable conductor 5.

[0031] In some further embodiments, the rotating ring 1 is provided with a guide plate 11, and the air distribution ring 2 is provided with a through hole 21. The guide plate 11 is configured to drive the rotating ring 1 to rotate relative to the air distribution ring 2 under the action of airflow in the through hole 21.

[0032] The guide plate 11 is set on the rotating ring 1. There are multiple guide plates 11, which are arranged circumferentially at intervals.

[0033] The through hole 21 is set on the air distribution ring 2. The airflow blows through the through hole 21 to the guide plate 11. As the airflow continuously blows out from the through hole 21, the airflow will continuously act on the guide plate 11. When acting on one of the guide plates 11, the guide plate 11 moves under the action of the airflow, thereby driving the rotating ring 1 to rotate relative to the air distribution ring 2. Since multiple guide plates 11 are arranged circumferentially, the rotating ring 1 will continuously rotate relative to the air distribution ring 2, thus satisfying the requirement that the airflow is continuously blown out from the air blowing pipe 4, and also allowing the air blowing pipe 4 to rotate, forming a spiral airflow.

[0034] In some further embodiments, the rotating ring 1 has a first annular cavity 10 inside, the first annular cavity 10 is opened in the inner ring wall of the rotating ring 1, and the first annular cavity 10 has an air outlet 110 facing away from the direction of the cable conductor 5, and the air outlet 110 is connected to the air blowing pipe 4.

[0035] The rotating ring 1 has a hollow interior, which is the first annular cavity 10. The opening of the first annular cavity 10 is in the inner wall of the rotating ring 1. The gas blown out from the air distribution ring 2 will enter the interior of the first annular cavity 10 through the opening of the first annular cavity 10, and at the same time flow into the air blowing pipe 4 from the air outlet 110.

[0036] The guide plate 11 is disposed on the inner sidewall of the first annular cavity 10. The guide plate 11 is located on the inner sidewall of the first annular cavity 10 and is arranged circumferentially at intervals. The guide plate 11 is transversely placed in the thickness direction of the first annular cavity 10. At the same time, the guide plate 11 is also radially inclined with the rotating ring 1 so that one sidewall of the guide plate 11 is the side facing the airflow. This allows the airflow entering from the inner ring opening in the first annular cavity 10 to blow onto the sidewall of the guide plate 11, further driving the rotating ring 1 to rotate, thus achieving air blowing while rotating.

[0037] The air distribution ring 2 has a second annular cavity 20 inside, and the through hole 21 is located on the outer ring wall of the air distribution ring 2 and connects the first annular cavity 10 and the second annular cavity 20.

[0038] The second annular cavity 20 is the one corresponding to the first annular cavity 10 in the air distribution ring 2. The through hole 21 provided on the outer wall of the second annular cavity 20 is used to connect the first annular cavity 10 and the second annular cavity 20 so that the airflow can flow relatively.

[0039] In practice, the two end faces of the rotating ring 1, near the inner ring, and the two end faces of the air distribution ring 2, near the outer ring, can rotate through the bearing 12. The bearing 12 should be a sealed bearing 12 to meet the sealing requirements.

[0040] In some further embodiments, the side of the guide plate 11 facing the through hole 21 is perpendicular to the axis of the through hole 21.

[0041] In order to maximize the efficiency of the airflow driving the rotating ring 1 to rotate relative to the air distribution ring 2, the side of the guide plate 11 facing the through hole 21 is specially set to be perpendicular to the axis of the through hole 21, so that the airflow flowing out of the through hole 21 can be directly blown onto the guide plate 11 to improve the driving effect on the rotating ring 1.

[0042] In some further embodiments, the inner wall of the air distribution ring 2 is provided with a connecting frame, and the portion of the connecting frame located in the wire passage area is provided with a through hole for the cable conductor 5; the connecting frame includes a collar 210 and three circumferentially arranged connecting rods 200, one end of the connecting rod 200 is connected to the inner ring of the air distribution ring 2, and the other end is connected to the collar 210, through which the cable conductor 5 passes.

[0043] The connecting frame is provided with a first connecting plate 201 on both sides along the running direction of the cable conductor 5. The two first connecting plates 201 are connected to a second connecting plate 202 on opposite sides by a first spring 203. A spiral scraper 204 is connected between the two first connecting plates 201. The spiral scraper 204 passes through the through hole and is sleeved on the outer peripheral wall of the cable conductor 5.

[0044] The collar 210 has a first connecting plate 201 and a second connecting plate 202 on each side, and both are connected by a first spring 203.

[0045] Under the action of the first spring 203, the second connecting plate 202 can slide relative to its corresponding first connecting plate 201. The two ends of the spiral scraper 204 are respectively connected to the two second connecting plates 202, which are sleeved on the outside of the cable conductor 5 and are set through the collar 210.

[0046] When the cable conductor 5 is running, the stubborn debris on its upper part that is not blown away by the airflow will be scraped off by the spiral scraper 204. In order to avoid the spiral scraper 204 colliding hard with the debris on the cable conductor 5, a movable second connecting plate 202 and spiral scraper 204 are specially adopted. When the stubborn debris comes into contact with the spiral scraper 204, if it is not scraped off immediately, the stubborn debris will drive the spiral scraper 204 to move in the direction of the cable conductor 5. As the first spring 203 on the side of the collar 210 away from the direction of the cable conductor 5 is compressed and the second spring 37 on the side of the collar 210 facing the direction of the cable conductor 5 is stretched, the resistance on the spiral scraper 204 driven by the stubborn impurities will become greater and greater. That is, the stubborn impurities will also be subjected to a greater scraping force by the spiral scraper 204 and will eventually be scraped off by the spiral scraper 204. After that, the first springs 203 on both sides of the collar 210 will return to their original state.

[0047] As the cable conductor 5 continues to run, the spiral scraper 204 undergoes irregular reciprocating motion under the action of two sets of first springs 203, thereby cleaning and scraping away stubborn impurities on the outer peripheral wall of the cable conductor 5.

[0048] The spiral scraper 204 can be made of stainless steel.

[0049] In practice, the first connecting plate 201 is bolted to the connecting frame; both the first connecting plate 201 and the second connecting plate 202 can be replaced to accommodate cable conductors 5 of different sizes.

[0050] In some further embodiments, the scraping frame 3 includes a rotating sleeve 30, with sliding blocks 32 symmetrically slidably provided on the side wall of the rotating sleeve 30. The scraping member 31 is arranged around the cable conductor 5, and both ends of the scraping member 31 are connected to the sliding blocks 32. The two free ends of the scraping member 31 after it is wrapped around the cable conductor 5 are both connected to the corresponding sliding blocks 32. By radially adjusting the sliding blocks 32, the tightness of the cable conductor 5 can be changed.

[0051] The scraping component 31 has a certain degree of flexibility, thus enabling it to wrap around the cable conductor 5.

[0052] Along the length of the cable conductor 5, multiple scraping parts 31 are sequentially and alternately connected to two sliding blocks 32.

[0053] The staggered arrangement of the scraping elements 31 can prevent the cable conductor 5 from bending or tilting due to the force exerted in the same direction. That is, the aforementioned sliding block 32 is provided in two sets and is arranged symmetrically, so that the force exerted by the scraping elements 31 on the cable conductor 5 is balanced and the coaxiality of the cable conductor 5 is guaranteed during operation.

[0054] In some further embodiments, each of the two sliding blocks 32 is provided with an adjusting plate 33; an adjusting rod 34 is passed through the two adjusting plates 33, and a second spring 37 is sleeved on the adjusting rod 34, with the second spring 37 located between the two adjusting rods 34.

[0055] An adjusting nut 35 is screwed onto the end of the adjusting rod 34. The adjusting nut 35 is located on the side of the adjusting plate 33 facing away from the second spring 37.

[0056] The tightness of the scraping part 31 can be adjusted to suit various cable conductors 5 of different thicknesses, thus accommodating a wider range of models. Additionally, the scraping force can be adjusted according to actual conditions.

[0057] When the two adjusting nuts 35 on the same adjusting rod 34 are rotated toward each other, the distance between the two sliding blocks 32 will decrease, the tension of the scraper 31 will decrease, and its force on the cable conductor 5 will also weaken. When the two adjusting nuts 35 on the same adjusting rod 34 are rotated away from each other, the distance between the two sliding blocks 32 will increase, the tension of the scraper 31 will increase, and its force on the cable conductor 5 will also strengthen.

[0058] In some further embodiments, the outer peripheral wall of the rotating sleeve 30 is provided with two sets of rotating support rings 300.

[0059] The frame is equipped with a rotating roller 36 for supporting the rotation of the rotating sleeve 30.

[0060] Two sets of support rings 300 are respectively set close to both ends of the rotating sleeve 30 to ensure the balance of the support.

[0061] Each rotating support ring 300 can have three rotating rollers 36, one of which is a driving roller and the other two are driven rollers. The three rotating rollers 36 are circumferentially spaced to achieve the rotation of the scraping frame 3.

[0062] The scraper 31 is partially wrapped around the cable conductor 5, thereby cleaning the oxide layer on the surface of the cable conductor 5.

[0063] In some further embodiments, a guide platform 6 is provided on the end face of the rotating ring 1 that runs toward the cable conductor 5, and a guide slope 60 is provided on the end face of the guide platform 6 that faces the scraper 3. The distance between the guide slope 60 and the scraper 3 first increases and then decreases. The rotating sleeve 30 is provided with an abutment rod 7, and the end of the abutment rod 7 away from the rotating sleeve 30 slides against the guide inclined surface 60.

[0064] When the scraper 3 rotates, the low connecting rod on it abuts against the guide slope 60 on the guide table 6. As the distance between the guide slope 60 and the scraper 3 gradually changes, when the scraper 3 rotates, under the action of the guide slope 60 and the abutting rod 7, the entire scraper 3 will repeatedly move in a straight line along the axial direction of the cable conductor 5, that is, sometimes moving away from the running direction of the cable conductor 5 and sometimes moving towards the running direction of the cable conductor 5. Thus, the scraper 31 can not only perform circumferential scraping and grinding on the cable conductor 5, but also perform axial scraping and grinding on the cable conductor 5, so as to improve the treatment effect on the oxide layer on the outer peripheral wall of the cable conductor 5.

[0065] In some further embodiments, a sliding cavity 61 is provided on the guide slope 60, and an annular groove is provided at one end of the sliding cavity 61 facing the scraper 3; a universal ball 70 is provided at one end of the abutment rod 7 passing through the annular groove; an annular slide rail 620 is provided on one inner side wall of the sliding cavity 61 facing away from the scraper 3, a slider 62 is provided on the annular slide rail 620, a baffle 71 is provided on the abutment rod 7, and a third spring 700 is provided between the baffle 71 and the slider 62, and the third spring 700 is sleeved on the abutment rod 7.

[0066] The abutment rod 7 passes through the annular groove and has a universal ball 70 at one end. The universal ball 70 abuts against a side wall of the sliding cavity 61 facing away from the scraper 3.

[0067] The abutment rod 7 rotates along with the scraping component 31 via the annular slide rail 620 and the slider 62. The abutment rod 7 slides through the slider 62, and as it rotates, the abutment rod 7 will make periodic movements along the axial direction of the slider 62.

[0068] To ensure that the universal ball 70 on the abutment rod 7 can always abut against the annular groove, a third spring 700 is also sleeved on the part of the abutment rod 7 located in the annular groove. At the same time, a baffle 71 is set on the end of the abutment rod 7 near the universal ball 70. The two ends of the third spring 700 abut against the baffle 71 and the slider 62 respectively, thereby ensuring that the abutment rod 7 can always abut against the annular groove while moving circumferentially with the scraping frame 3.

[0069] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
