Description

Technical Field

[0001] This invention relates to the field of cable processing technology, and in particular to a conductor surface treatment apparatus for cable manufacturing. Background Technology

[0002] During cable processing, insulation material needs to be wrapped around the outside of the cable conductor to ensure the cable's insulation performance. When wrapping cross-linked polyethylene cables, the extrusion temperature of the insulation material is as high as 120℃~220℃. When the conductor temperature is low, the extruded molten material cools down rapidly when it comes into contact with the conductor, resulting in insufficient adhesion and affecting the quality of the produced cable. Therefore, the conductor of the cable needs to be preheated before wrapping it during cable processing.

[0003] For example, the patent application CN118116662B, entitled "A Simple Cable Conductor Preheating Device and Its Usage Method," describes a method where a first water pump pumps water from a storage tank to a first and second spray pipe to clean the cable conductor. Simultaneously, a heating wire heats the water in the storage tank, thus simultaneously heating the cable conductor during the cleaning process.

[0004] When treating the surface of a cable, it is not only necessary to preheat it, but also to remove oil and dust to prevent affecting the coating effect. Therefore, the cable conductor needs to be cleaned before coating. After cleaning, a lot of water droplets will be attached to the surface of the cable conductor. During preheating, the evaporation of water droplets is a process that requires a lot of heat energy, which will affect the preheating effect of the cable conductor. When the preheating effect of the cable conductor is not good, it will affect the adhesion between the insulation material and the conductor during the subsequent coating, thus affecting the quality of the cable. Summary of the Invention

[0005] The purpose of this invention is to provide a conductor surface treatment apparatus for cable manufacturing, which enables the drying cotton to be used to dry the cable conductor from all areas around it, preventing localized drying from causing the drying cotton to absorb excessive moisture in certain areas, thus preventing the drying effect from being affected. This also prevents insufficient adhesion between the insulation material and the conductor due to the low temperature of the cable conductor, thereby improving the quality of cable production and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a conductor surface treatment apparatus for cable manufacturing, comprising a mounting frame, a cleaning component for cleaning the conductor surface disposed on the right side of the mounting frame, and a preheating component for preheating the conductor disposed on the left side of the mounting frame; the conductor surface treatment apparatus further comprises:

[0007] A drying assembly is configured in the middle part of the mounting frame. The drying assembly includes a fixed frame that is fixedly connected to the middle part of the mounting frame. An external toothed ring is rotatably connected to the middle part of the inner side of the fixed frame. A drying cover is fixedly connected inside the external toothed ring. A drying shaft is rotatably connected inside the drying cover. Fixed rings are fixedly connected to both sides of the outer wall of the drying shaft. A drying cotton is fixedly connected between the outer sides of the two fixed rings.

[0008] The drive assembly, located in the middle part of the fixed frame, is used to drive the external gear ring to rotate.

[0009] A transmission assembly, located on the right side of the drying shaft, is used to cause the drying shaft to rotate around its axis, carrying the drying cotton.

[0010] The drive assembly includes a motor fixedly connected to the top of the fixed frame. The output shaft of the motor is fixedly connected to a first gear. The outer side of the first gear meshes with an external gear ring. The fixed frame has a slot near the first gear.

[0011] The transmission assembly includes a bent frame fixedly connected to the right side of the fixed frame, with an internal gear ring fixedly connected to the end of the bent frame. The transmission assembly also includes a second gear fixedly connected to the end of the drying shaft, with the inner side of the internal gear ring meshing with the second gear.

[0012] An extension rod is fixedly connected inside the drying cover. The end of the extension rod extends into the drying shaft and is fixedly connected to a disc. The outer side of the extension rod is rotatably connected to the drying cover. A moving rod is slidably connected in a ring array to the outer side of the drying shaft. A push plate is fixedly connected to the end of the moving rod away from the extension rod. A moving block is fixedly connected to the end of the moving rod near the extension rod. A pressing frame is fixedly connected to the outer side of the disc. A rotating shaft for reducing motion friction is rotatably connected to the inner side of the pressing frame.

[0013] The moving block has rounded corners near the disk, and the top of the moving block is fixedly connected to the drying shaft by the first spring.

[0014] The bottom of the drying cover is equipped with a wringing assembly, which includes a bottom half-ring fixedly connected to the inside of the fixed frame. The wringing assembly also includes a lifting rod slidably connected to the bottom of the drying cover. The end of the lifting rod near the bottom half-ring is rotatably connected to a ball for reducing motion friction. The end of the lifting rod away from the bottom half-ring is fixedly connected to a wringing frame. Drain pipes are fixedly inserted into both sides of the drying cover. A second spring is fixedly connected between the wringing frame and the drying cover.

[0015] The two ends of the bottom half ring are set at an angle.

[0016] The preheating assembly includes a drying cylinder fixedly connected to the left side of the mounting bracket, and a drying hole is provided on the inner side of the drying cylinder.

[0017] A drying component is configured between the preheating component and the drying component. The drying component includes a connecting cover fixedly connected to both sides of the drying cylinder. The connecting cover is narrowed at the point away from the drying cylinder. The drying component also includes a gas collecting ring fixedly connected to the outside of the drying cover. A rotating ring is rotatably connected to the left side of the gas collecting ring. A connecting pipe is fixedly inserted between the rotating ring and the drying cylinder. The drying component also includes a gas channel opened inside the drying cover. An air jet hole is opened at the front end of the inner side of the drying cover.

[0018] The interior of the rotating ring is connected to the interior of the gas channel.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The wiping cotton rotates around the axis of the fixed frame, which can dry the cable conductor. At the same time, under the action of meshing with the second gear on the inner side of the internal gear ring, the wiping cotton rotates around the axis of the wiping shaft. This allows all areas around the wiping cotton to be used to dry the cable conductor, preventing localized wiping from causing excessive moisture absorption in certain areas, thus preventing the wiping effect from being affected. This reduces the amount of water droplets remaining on the cable conductor, thereby preventing residual water droplets from affecting the preheating effect of the cable conductor. This also prevents insufficient adhesion between the insulation material and the conductor due to low cable conductor temperature, thus improving the quality of cable production.

[0021] 2. When the moving rod and push plate move, the wiping cotton can shake regularly. The regular shaking makes the wiping action no longer a continuous rolling motion, but a series of point contact with instantaneous separation. This helps to disperse or be carried away by the collection device instead of being reapplied, thereby further improving the wiping effect and preventing residual water droplets from affecting the preheating effect of the cable conductor. This can prevent the insulation material from not adhering tightly to the conductor due to the low temperature of the cable conductor, and further improve the quality of cable production.

[0022] 3. When the drying cover rotates to the lower half with the outer toothed ring, the ball at the end of the lifting rod can rotate to the position of the bottom half ring. Under the limiting action of the bottom half ring, the lifting rod can move the water squeezing frame closer to the drying cotton. At this time, the water squeezing frame contacts the position of the drying cotton to the conductor of the cable. As the pushing plate continuously pushes the drying cotton, the drying cotton shakes, which allows the drying cotton to continuously cooperate with the water squeezing frame to squeeze out the absorbed water. This can prevent the drying effect from being affected by the drying cotton absorbing too much water, and thus prevent the effect of the cable conductor preheating from being affected by the residual water droplets. This can prevent the insulation material from not being tightly bonded to the conductor due to the low temperature of the cable conductor, and further improve the quality of cable production.

[0023] 4. Hot air is sprayed from the jet nozzle onto the wiping cotton after the water has been squeezed out, thereby further improving the drying effect of the wiping cotton and the drying effect of the cable conductor. This prevents residual water droplets from affecting the preheating effect of the cable conductor, thus preventing insufficient adhesion between the insulation material and the conductor due to the low temperature of the cable conductor, and further improving the quality of cable production.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1: Please refer to Figures 1 to 10 This invention provides a technical solution: a conductor surface treatment device for cable manufacturing, including a mounting frame 1. A cleaning component 2 for cleaning the conductor surface is disposed on the right side of the mounting frame 1, and a preheating component 3 for preheating the conductor is disposed on the left side of the mounting frame 1. The preheating component 3 includes a drying cylinder 31 fixedly connected to the left side of the mounting frame 1. A drying hole 32 is provided on the inner side of the drying cylinder 31. During drying, heated high-temperature air can be introduced into the interior of the drying cylinder 31. The high-temperature air is sprayed through the drying hole 32 onto the inner side of the drying cylinder 31 and contacts the cable conductor, thereby preheating the cable conductor. This prevents the extruded molten material from rapidly solidifying and cooling when it is bonded to the conductor during subsequent conductor coating, thus preventing insufficient adhesion and improving the quality of the produced cable. Therefore, the conductor of the cable needs to be preheated before coating.

[0041] It should be noted that when processing the cable conductor, the end of the cable needs to pass through the inside of the cleaning ring, the fixing frame 41 and the drying cylinder 31, and the cable is pulled by an external traction device. This design allows for continuous processing of the cable surface.

[0042] The cleaning component 2 includes a cleaning ring fixedly connected to the right side of the mounting bracket 1. A soft brush is fixedly connected to the inner side of the cleaning ring, and a water spray hole is opened on the inner side of the cleaning ring. During cleaning, the cleaning water can be sprayed onto the conductor through the water spray hole by the inside of the cleaning ring. Since the cable conductor is continuously moved under traction during the cable conductor processing, the soft brush can clean and brush the cable conductor. This design can remove oil and dust on the cable conductor, thereby preventing oil and dust from affecting the tightness of the subsequent cable wrapping.

[0043] The conductor surface treatment apparatus also includes a drying assembly 4 disposed in the middle part of the mounting frame 1. The drying assembly 4 includes a fixing frame 41 fixedly connected to the middle part of the mounting frame 1. An external toothed ring 42 is rotatably connected to the inner middle part of the fixing frame 41. A drying cover 43 is fixedly connected inside the external toothed ring 42. A drying shaft 44 is rotatably connected inside the drying cover 43. Fixing rings 45 are fixedly connected to both sides of the outer wall of the drying shaft 44. A drying cotton 46 is fixedly connected between the outer sides of the two fixing rings 45. The conductor surface treatment apparatus also includes a driving assembly 5 disposed in the middle part of the fixing frame 41. The driving assembly 5 is used to drive the external toothed ring 42 to rotate. The conductor surface treatment apparatus also includes a... The transmission assembly 6 is located on the right side of the drying shaft 44. The transmission assembly 6 is used to make the drying shaft 44 rotate around the axis of the drying shaft 44 with the drying cotton 46. The drive assembly 5 includes a motor 51 fixedly connected to the top of the fixed frame 41. The output shaft of the motor 51 is fixedly connected to a first gear 52. The outer side of the first gear 52 meshes with an external gear ring 42. The fixed frame 41 has a slot 53 near the first gear 52. The transmission assembly 6 includes a bent frame 61 fixedly connected to the right side of the fixed frame 41. The end of the bent frame 61 is fixedly connected to an internal gear ring 62. The transmission assembly 6 also includes a second gear 63 fixedly connected to the end of the drying shaft 44. The inner side of the internal gear ring 62 meshes with the second gear 63.

[0044] By adopting the above technical solution, when it is necessary to remove the residual output on the surface of the cleaned cable conductor, the output shaft of the motor 51 is rotated, which causes the first gear 52 to rotate. At this time, under the action of the outer side of the first gear 52 meshing with the outer gear ring 42, the outer gear ring 42 can rotate accordingly, which in turn causes the drying cover 43 to rotate. This allows the drying shaft 44, the fixing ring 45 and the drying cotton 46 inside the drying cover 43 to rotate around the axis of the fixing frame 41.

[0045] It should be noted that the drying cotton 46 used for wiping is relatively thick, and in the initial state, the drying cotton 46 is compressed and becomes concave. This helps to increase the contact area between the conductor and the drying cotton 46 during wiping.

[0046] When the wiping cotton 46 rotates around the axis of the fixed frame 41, it can wipe the area around the cable conductor dry. The wiping cotton 46 rotates at a relatively fast speed around the axis of the fixed frame 41, and the wiping cotton 46 is relatively long to ensure that all parts of the cable conductor can be wiped dry, thus ensuring the drying effect of the cable conductor. This avoids water residue on the cable conductor, which would cause water droplets to evaporate and absorb a large amount of heat energy during the preheating of the cable conductor, thereby reducing the impact on the preheating effect of the cable conductor. In addition, it prevents the insulation material from not adhering tightly to the conductor due to the low temperature of the cable conductor, thereby further improving the quality of cable production.

[0047] While the drying shaft 44, fixing ring 45, and drying cotton 46 inside the drying cover 43 rotate around the axis of the fixing frame 41, the inner side of the internal gear ring 62 meshes with the second gear 63, allowing the drying shaft 44, fixing ring 45, and drying cotton 46 to rotate around the axis of the drying shaft 44. This design allows all areas around the drying cotton 46 to be used to dry the cable conductor, preventing localized drying from causing the drying cotton 46 to absorb too much moisture and thus affecting the drying effect. This further reduces the amount of water droplets remaining on the cable conductor, thereby preventing residual water droplets from affecting the preheating effect of the cable conductor. This also prevents insufficient adhesion between the insulation material and the conductor due to low cable conductor temperature, further improving the quality of cable production.

[0048] An extension rod 47 is fixedly connected inside the drying cover 43. The end of the extension rod 47 extends into the drying shaft 44 and is fixedly connected to a disc 48. The outer side of the extension rod 47 is rotatably connected to the drying cover 43. A moving rod 49 is slidably connected in a ring array to the outer side of the drying shaft 44. A push plate 410 is fixedly connected to the end of the moving rod 49 away from the extension rod 47. A moving block 411 is fixedly connected to the end of the moving rod 49 near the extension rod 47. A squeezing frame 412 is fixedly connected to the outer side of the disc 48. A rotating shaft 413 for reducing motion friction is rotatably connected to the inner side of the squeezing frame 412. The moving block 411 has a rounded corner near the disc 48. The top of the moving block 411 is fixedly connected to the drying shaft 44 by a first spring 414. The extension rod 47 is aligned with the axis of the drying shaft 44. The drying cotton 46 is made of a soft and elastic material.

[0049] By adopting the above technical solution, when the drying shaft 44, the fixing ring 45, and the drying cotton 46 rotate around the axis of the drying shaft 44, the extension rod 47 rotates relative to the drying shaft 44, the fixing ring 45, and the drying cotton 46. At this time, the moving rod 49 moves relative to the disc 48, the rotating shaft 413, and the extrusion frame 412. As the drying shaft 44, the fixing ring 45, and the drying cotton 46 rotate around the axis of the drying shaft 44, multiple moving rods 49 rotate along with the moving block 411 and the push plate 410. At this time, the moving block 411 rotates relative to the rotating shaft 413. When the moving block 411 rotates close to the rotating shaft 413, it will be limited by the rotating shaft 413. At this time, the moving block 411 can move along with the moving rod 49 and the push plate 410 towards the drying cotton 46, which can make the drying cotton 46 further close to the cable conductor, thereby making the drying cotton 46 further concave.

[0050] When the moving block 411 rotates away from the rotating shaft 413, the moving block 411, along with the moving rod 49 and the push plate 410, can be reset under the elastic force of the first spring 414.

[0051] It should be noted that in the initial state, under the elastic force of the first spring 414, the push plate 410 can make the drying cotton 46 fully contact the cable conductor, and there is a depression at the point where the drying cotton 46 contacts the cable conductor.

[0052] This design allows the drying cotton 46 to vibrate rhythmically during the drying of the cable conductor. This rhythmic vibration transforms the wiping action from a continuous rolling motion into a series of point-contact movements with momentary separations. This helps to disperse or collect the stripped liquid, preventing it from being reapplied, thus further improving the drying effect. It also prevents residual water droplets from affecting the preheating of the cable conductor, thus preventing insufficient adhesion between the insulation material and the conductor due to low conductor temperature, further improving the quality of cable production.

[0053] A wringing assembly 7 is provided at the bottom of the drying cover 43. The wringing assembly 7 includes a bottom half-ring 71 fixedly connected to the inside of the fixed frame 41. The wringing assembly 7 includes a lifting rod 72 slidably connected to the bottom of the drying cover 43. A ball 73 for reducing motion friction is rotatably connected to the end of the lifting rod 72 near the bottom half-ring 71. A wringing frame 74 is fixedly connected to the end of the lifting rod 72 away from the bottom half-ring 71. Drain pipes 75 are fixedly inserted into both sides of the drying cover 43. A second spring 76 is fixedly connected between the wringing frame 74 and the drying cover 43. The two ends of the bottom half-ring 71 are inclined.

[0054] By adopting the above technical solution, when the drying cover 43 rotates to the lower half with the outer toothed ring 42, the ball 73 at the end of the lifting rod 72 can rotate to the position of the bottom half ring 71. Under the limiting action of the bottom half ring 71, the lifting rod 72 can move with the water squeezing frame 74 close to the position of the drying cotton 46. At this time, the water squeezing frame 74 contacts the position of the drying cotton 46 to carry the cable conductor. Since the push plate 410 continuously pushes the drying cotton 46 to make the drying cotton 46 shake, the drying cotton 46 can continuously cooperate with the water squeezing frame 74 to squeeze out the absorbed water. This design can prevent the drying effect from being affected by the drying cotton 46 absorbing too much water, and thus prevent the effect of cable conductor preheating from being affected by residual water droplets. This can prevent the insulation material from not being tightly bonded to the conductor due to the low temperature of the cable conductor, and further improve the quality of cable production.

[0055] It should be noted that the water squeezing rack 74 has a drain hole to facilitate the flow of squeezed water. The squeezed water falls into the drying cover 43 and is discharged from the drain pipe 75.

[0056] It should be noted that the bottom half ring 71 is located in the lower half of the fixed frame 41. When the drying cover 43 rotates to the upper half with the outer toothed ring 42, the water squeezing frame 74 remains away from the drying cotton 46 under the elastic force of the second spring 76. This prevents the drying cover 43 from squeezing water from the drying cotton 46 when it rotates to the lower half with the outer toothed ring 42, thus preventing the squeezed water from falling onto the drying conductor due to gravity and further avoiding any situation that may affect the drying effect.

[0057] Example 2: The technical solution of this example differs from that of Example 1 in that: Figures 1 to 5 and Figures 11 to 12 A drying assembly 8 is configured between the preheating assembly 3 and the drying assembly 4. The drying assembly 8 includes a connecting cover 81 fixedly connected to both sides of the drying cylinder 31. The connecting cover 81 is narrowed away from the drying cylinder 31 to prevent hot air leakage. The drying assembly 8 also includes a gas collecting ring 82 fixedly connected to the outside of the drying cover 43. A rotating ring 83 is rotatably connected to the left side of the gas collecting ring 82. A connecting pipe 84 is fixedly inserted between the rotating ring 83 and the drying cylinder 31. The drying assembly 8 also includes a gas channel 85 opened inside the drying cover 43. An air jet hole 86 is opened at the front end of the inner side of the drying cover 43. The interior of the rotating ring 83 is connected to the interior of the gas channel 85.

[0058] By adopting the above technical solution, the excess air after preheating enters the connecting cover 81 and enters the interior of the air collecting ring 82 through the connecting pipe 84. Then, it enters the front end of the drying cover 43 through the gas channel 85 and is finally sprayed from the jet hole 86 onto the drying cotton 46 after the water has been squeezed out. This further improves the drying effect on the drying cotton 46 and the drying effect on the cable conductor. In this way, it prevents the effect of residual water droplets from affecting the preheating effect of the cable conductor. This can prevent the insulation material from not being tightly bonded to the conductor due to the low temperature of the cable conductor, and further improve the quality of cable production.

[0059] It should be noted that the design of the rotatable connection between the air collecting ring 82 and the rotating ring 83 ensures that this part of the structure does not affect the rotation of the drying cover 43.

[0060] It should be noted that the wiping cotton 46 is first squeezed dry and then rotated to the front end of the wiping cover 43 for drying.

[0061] Working principle: When processing the cable conductor, the end of the cable needs to pass through the inside of the cleaning ring, the fixing frame 41, and the drying cylinder 31, and the cable is pulled by an external traction device. This design allows for continuous treatment of the cable surface. A soft brush is fixedly connected to the inside of the cleaning ring, and water spray holes are opened on the inside of the cleaning ring. During cleaning, the cleaning water can be sprayed onto the conductor through the water spray holes by the inside of the cleaning ring. Since the cable conductor is continuously moved by traction during the cable conductor processing, the soft brush can clean and brush the cable conductor. This design can remove oil and dust on the cable conductor, thereby preventing oil and dust from affecting the tightness of the subsequent cable wrapping.

[0062] When it is necessary to remove residual output from the surface of the cleaned cable conductor, the output shaft of motor 51 is rotated, causing the first gear 52 to rotate. The outer side of the first gear 52 meshes with the external gear ring 42, causing the external gear ring 42 to rotate as well. This causes the drying cover 43 to rotate, allowing the drying shaft 44, fixing ring 45, and drying cotton 46 inside the drying cover 43 to rotate around the axis of the fixing frame 41. The drying cotton 46 dries the conductor. While the drying shaft 44, fixing ring 45, and drying cotton 46 inside the cover 43 rotate around the axis of the fixing frame 41, they also mesh with the second gear 63 on the inner side of the internal gear ring 62. This allows the drying shaft 44, fixing ring 45, and drying cotton 46 to rotate around the axis of the drying shaft 44. This ensures that all areas around the drying cotton 46 can be used to dry the cable conductor, preventing localized drying from causing the drying cotton 46 to absorb too much moisture and thus affecting the drying effect.

[0063] When the drying shaft 44, the fixing ring 45, and the drying cotton 46 rotate around the axis of the drying shaft 44, the extension rod 47 rotates relative to the drying shaft 44, the fixing ring 45, and the drying cotton 46. At this time, the moving rod 49 moves relative to the disc 48, the rotating shaft 413, and the extrusion frame 412. As the drying shaft 44, the fixing ring 45, and the drying cotton 46 rotate around the axis of the drying shaft 44, multiple moving rods 49 rotate along with the moving block 411 and the push plate 410. At this time, the moving block 411 rotates relative to the rotating shaft 413. When the moving block 411 rotates close to the rotating shaft 413, it will be limited by the rotating shaft 413. This allows the moving block 411 to rotate. Moving the moving rod 49 and the push plate 410 towards the drying cotton 46 allows the drying cotton 46 to get closer to the cable conductor, thus causing the drying cotton 46 to become more concave. When the moving block 411 rotates away from the rotating shaft 413, the elastic force of the first spring 414 allows the moving block 411, along with the moving rod 49 and the push plate 410, to return to its original position. This allows the drying cotton 46 to vibrate regularly when drying the cable conductor. The regular vibration makes the wiping action no longer a continuous rolling motion, but a series of point contact with instantaneous separation. This helps to scatter or collect the stripped liquid, rather than reapplying it, thereby further improving the drying effect.

[0064] Excess air after preheating enters the connecting cover 81 and enters the air collecting ring 82 through the connecting pipe 84. Then it enters the front end of the drying cover 43 through the gas channel 85 and is finally sprayed from the jet hole 86 onto the drying cotton 46 after the water has been squeezed out, thereby further improving the drying effect on the drying cotton 46 and further improving the drying effect on the cable conductor.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
