Description

Technical Field

[0001] This application relates to the field of cable processing technology, and in particular to a shielding layer covering device for cable processing. Background Technology

[0002] Cables are a general term encompassing optical cables, electrical cables, and similar types, playing a vital role in control installation, equipment connection, and power transmission. In cable manufacturing, sheathing is a key process. Depending on the specific performance requirements of the cable, different materials are wrapped around the conductor using sheathing devices. Shielding layer sheathing devices are specialized equipment used to wrap a shielding layer around the outside of the cable. This is achieved by stably placing and horizontally moving the cable core, then using a winding mechanism to wrap the shielding layer around the outer wall of the core, thus preventing external interference during signal transmission.

[0003] However, existing shielding layer covering devices still have some drawbacks in use: First, since the shielding layer is placed on the cable core by a single-layer winding method, and the shielding layer does not fit tightly with the outer wall of the cable core during winding, the finished cable needs to be bent and rolled multiple times in actual use. The seams formed by the winding of the shielding layer will increase, resulting in low anti-interference effect of the cable. Second, the cable core of the stranded cable often has some burrs or dust on its surface, which reduces the appearance quality of the cable. If the cable core is directly covered, it will cause uneven shielding layer coverage, resulting in bulges, and even affecting the physical properties of the finished cable. Summary of the Invention

[0004] This application proposes a shielding layer covering device for cable processing, which has the advantages of effectively improving the covering effect of the shielding layer on the cable core and effectively removing burrs and dust from the surface of the cable core, thereby solving the problem of poor quality of finished cables caused by poor winding effect.

[0005] To achieve the above objectives, this application adopts the following technical solution: a shielding layer covering device for cable processing, comprising:

[0006] A working mechanism for placing the cable core and guiding its horizontal movement, the working mechanism including a placement platform;

[0007] A left limiting mechanism is provided on the top left side of the placement platform, and the left limiting mechanism consists of a fixing mechanism and a winding mechanism, which is used to wind the first shielding layer around the cable core.

[0008] The right limiting mechanism is provided on the top right side of the placement platform, and the right limiting mechanism consists of a fixing mechanism and a winding mechanism, which is used to wind the second shielding layer around the cable core.

[0009] A power mechanism is provided at the top of the placement platform in front of the left and right limiting mechanisms to provide power for the rotation of the winding mechanism. The power mechanism consists of a rotary motor, a rotary shaft, a rotary plate, a first rotary gear, a second rotary gear, and a rotating component. The rotary motor is located at the top of the placement platform to the left of the left limiting mechanism, and the rotary plate is located at the top of the placement platform to the right of the right limiting mechanism. One end of the rotary shaft is movably connected to the rotary motor, and the other end of the rotary shaft is movably sleeved with the rotary plate. The left half of the rotary shaft is fixedly sleeved with the first rotary gear, which meshes with the winding mechanism on the left limiting mechanism. The right half of the rotary shaft is fixedly sleeved with the second rotary gear, which meshes with the rotating component. The rotating component meshes with the winding mechanism on the right limiting mechanism. One end of the rotating component is movably engaged with the rotary plate. The first and second rotary gears have the same number of teeth.

[0010] Furthermore, the working mechanism also includes:

[0011] Two guide rollers are fixedly installed at the top of the placement platform, with one guide roller located to the left of the left limiting mechanism and the other guide roller located to the right of the right limiting mechanism.

[0012] Furthermore, the fixing mechanism includes:

[0013] The fixed housing is composed of a cuboid and a cylinder, and a fixing hole is opened in the fixed housing located on the cylinder. The diameter of the fixing hole located in the left limiting mechanism is smaller than the diameter of the fixing hole located in the right limiting mechanism. A fixing groove is opened on one side of the fixed housing located outside the fixing hole, and the fixed housing is movably sleeved with the winding mechanism through the fixing groove.

[0014] The friction assembly has a frustum groove on one side of the fixing hole of the fixed housing, and the fixed housing is fixedly connected to the friction assembly through the frustum groove. The friction assembly is located on the side of the fixed housing near the guide roller, and the friction assembly is annular in shape.

For the rotating gear in the left limiting mechanism, the rotating gear meshes with the first rotating gear. For the rotating gear in the right limiting mechanism, the rotating gear meshes with the rotating component. The two friction components are the same size.

[0020] A rotating component, one end of which is fixedly connected to one side wall of the rotating gear, the rotating component is located in a fixed groove, and the width of the rotating component is equal to the width of the deformation bladder. The rotating component is a quarter-circle arc and the shape of the rotating component is crescent-shaped.

[0022] A shielding roller, one end of which is fixedly connected to the other side wall of the rotating gear, and the shielding roller is correspondingly arranged with the rotating component. A shielding layer roll is installed on the shielding roller. The length of the shielding roller located in the left limiting mechanism is shorter than the length of the shielding roller located in the right limiting mechanism, and the shielding layer wound by the shielding roller located in the right limiting mechanism covers the seam of the shielding layer wound by the shielding roller located in the left limiting mechanism.

[0023] Furthermore, it also includes:

[0024] A support mechanism is fixedly installed on the top of the placement platform located between the left and right limiting mechanisms to enhance the stability during the cable wrapping process.

[0025] Furthermore, the support mechanism includes:

[0026] A support housing, the bottom end of which is fixedly connected to the placement platform, and a support groove is provided at the top end of the support housing;

[0027] A movable component is provided at the bottom end of the support groove of the support housing for storing gas from the deformation bladder;

[0028] A liquid storage component is provided in the support groove of the support housing above the movable component, and is used for applying glue;

[0029] Supporting air pipes are fixedly sleeved on both sides of the supporting shell below the liquid storage component. One end of the supporting air pipe is connected to the supporting groove, and the other end of the supporting air pipe is connected to the upper space of the supporting shell.

[0030] Furthermore, the moving component includes:

[0031] The movable bladder is made of a vertically expandable and deformable rubber material, and the upper and lower walls of the movable bladder are connected by a movable spring. The other end of the movable bladder passes through the support shell and is fixedly connected to the movable bladder. The bottom end of the movable bladder is fixedly connected to the bottom end of the support groove.

[0032] The top end of the movable bladder is fixedly connected to the movable plate.

[0033] Furthermore, the liquid storage assembly includes:

[0034] A liquid storage plate is fixedly sleeved in the support groove of the supporting shell;

[0035] A rolling shaft is movably engaged in a support groove located above the liquid storage plate, and the highest wall surface of the rolling shaft is in contact with the cable. The liquid storage plate is filled with adhesive, and the initial height of the adhesive is flush with the middle height of the rolling shaft.

[0036] A sealing membrane, the top edge of which is fixedly connected to the bottom edge of the liquid storage plate, the sealing membrane having a deformation effect;

[0037] A movable bob rod, one end of which is fixedly connected to a sealing membrane, and the other end of which passes through a liquid storage plate and contacts a rolling shaft, wherein the movable bob rod is made of plastic.

[0038] This application has the following beneficial effects:

[0039] This application provides a shielding layer covering device for cable processing. By setting a power mechanism, a left limiting mechanism, and a right limiting mechanism on the working mechanism, and with both the left and right limiting mechanisms consisting of a fixing mechanism and a winding mechanism, during operation, the first rotating gear on the power mechanism drives the winding mechanism on the left limiting mechanism to rotate forward, and the second rotating gear and rotating component on the power mechanism drive the winding mechanism on the right limiting mechanism to rotate in the opposite direction. This winds two shielding layers onto the outer wall of the cable core in opposite directions. Simultaneously, the outer shielding layer covers the seam of the inner shielding layer, effectively improving the tightness of the fit between the shielding layer and the cable core. This ensures that the finished cable will not experience increased seam width after multiple bends and rolls during actual use, thus enhancing the cable's anti-interference effect.

[0040] By setting friction components and movable components within the fixed housing, when the rotating component rotates along the fixed groove of the fixed housing, the rotating component generates magnetic repulsion on the movable components at different positions, thereby pushing the movable plate to move within the movable tube. This effectively promotes the airflow to be discharged towards the friction components. Thus, during the horizontal movement of the cable core, the friction component located in the left limiting mechanism effectively rubs against the outer wall of the cable core, and in conjunction with the airflow blowing of the movable component, cleans the burrs and dust attached to the outer wall of the cable core out of the fixing hole of the fixed mechanism. The friction component located in the right limiting mechanism, in conjunction with the airflow blowing of the movable component, effectively squeezes the cable covered with the shielding layer, further improving the tightness between the two.

[0041] By setting a support mechanism on the placement platform between the left and right limiting mechanisms, the support force of the cable section located between the left and right limiting mechanisms is effectively improved, preventing the cable from sagging and affecting the winding effect when the left and right limiting mechanisms are winding downwards at the same time. At the same time, a liquid storage component is set in the support mechanism, and the glue stored in the liquid storage plate is applied to the inner shielding layer by a rolling shaft, which effectively improves the tightness of the connection between the inner and outer shielding layers.

[0042] By setting a deformation bladder in the lower half of the fixed groove of the fixed housing, and the deformation bladder being connected to the moving component in the support mechanism through a fixed air tube, when the left and right limiting mechanisms are simultaneously wound downwards, the rotating component squeezes the deformation bladder, causing the gas inside the deformation bladder to be transferred to the moving bladder, thereby pushing the moving plate upwards, reducing the gap between the moving plate and the liquid storage plate, and exhausting the airflow between them through the support air tube, further providing an upward thrust to the cable. In addition, when the glue height in the liquid storage plate is lower than the lowest wall height of the rolling shaft, the upward movement of the moving bladder effectively pushes the sealing film and the moving hair rod upwards and into contact with the rolling shaft, thereby effectively applying the glue adhering to the moving hair rod to the outside of the rolling shaft, further improving the glue utilization rate.

[0060] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. Example

[0061] A shielding layer covering device for cable processing, comprising:

[0062] Please see Figure 1 , Figures 3-4 The working mechanism 1 is used to place the cable core and guide the cable core to move horizontally. The working mechanism 1 consists of a placement platform 11 and guide rollers 12. Two guide rollers 12 are fixedly installed at the top of the placement platform 11. One guide roller 12 is located to the left of the left limiting mechanism 3a and the other guide roller 12 is located to the right of the right limiting mechanism 3b. It can support and guide the cable core to move from left to right on the working mechanism 1, thereby improving the stability of the cable during the coating process.

[0063] Please see Figure 1 , Figures 3-4 The left limiting mechanism 3a is provided on the top left side of the placement platform 11. The left limiting mechanism 3a is composed of a fixing mechanism 3 and a winding mechanism 4, and is used to wind the first shielding layer around the cable core.

[0064] Please see Figure 1 , Figures 3-4 The right limiting mechanism 3b is provided on the top right side of the placement platform 11. The right limiting mechanism 3b is composed of a fixing mechanism 3 and a winding mechanism 4, and is used to wind the second shielding layer around the cable core.

[0065] Please see Figures 1-2 The power mechanism 2 is located at the top of the placement platform 11 in front of the left limiting mechanism 3a and the right limiting mechanism 3b. It provides power for the rotation of the winding mechanism 4. The power mechanism 2 consists of a rotary motor 21, a rotary shaft 22, a rotary plate 23, a first rotary gear 24, a second rotary gear 25, and a rotating component 26. The rotary motor 21 is located at the top of the placement platform 11 to the left of the left limiting mechanism 3a, and the rotary plate 23 is located at the top of the placement platform 11 to the right of the right limiting mechanism 3b. One end of the rotary shaft 22 is movably connected to the rotary motor 21, and the other end is movably sleeved with the rotary plate 23, effectively ensuring the stability of the rotary shaft 22. The left half of the rotary shaft 22 is fixedly sleeved with the first rotary gear 24, which meshes with the winding mechanism 4 on the left limiting mechanism 3a. When the rotary shaft 22 rotates, it can drive the left limiting mechanism 4 through the first rotary gear 24. The winding mechanism 4 on structure 3a rotates in the forward direction to achieve the first layer of winding on the outer wall of the cable. The right half of the rotating shaft 22 is fixedly sleeved with the second rotating gear 25, and the second rotating gear 25 meshes with the rotating part 26. The rotating part 26 meshes with the winding mechanism 4 on the right limiting mechanism 3b. When the rotating shaft 22 rotates, it can drive the winding mechanism 4 on the left limiting mechanism 3a to rotate in the reverse direction through the second rotating gear 25 and the rotating part 26, thereby achieving the second layer of winding on the outer wall of the cable. One end of the rotating part 26 is movably engaged with the rotating plate 23, effectively ensuring the stability of the rotating part 26. The first rotating gear 24 and the second rotating gear 25 have the same number of teeth, effectively ensuring that the rotating shaft 22 can drive the first rotating gear 24 and the second rotating gear 25 to rotate the same number of teeth in one rotation, thus laying the foundation for the winding mechanism 4 on the left limiting mechanism 3a and the right limiting mechanism 3b to rotate at the same speed.

[0066] Please see Figures 3-8 The fixed mechanism 3 includes:

[0067] The fixed housing 31 is composed of a cuboid and a cylinder, and a fixing hole is opened in the fixed housing 31 located on the cylinder. The cable core can pass through the fixing hole, and the fixed housing 31 can support the cable core through the fixing hole. The diameter of the fixing hole located in the left limiting mechanism 3a is smaller than the diameter of the fixing hole located in the right limiting mechanism 3b, because the overall diameter of the cable increases after the wrapping operation. This fixing hole setting can effectively protect the appearance of the cable. A fixing groove is opened on one side of the fixed housing 31 outside the fixing hole, and the fixed housing 31 is movably sleeved with the winding mechanism 4 through the fixing groove to ensure the stability of the winding mechanism 4 when it rotates.

[0068] Please see Figures 3-5 , Figures 9-10 The winding mechanism 4 includes:

[0069] Rotating gear 41 is located outside the fixed housing 31 and is coaxial with the fixed housing 31. For rotating gear 41 in the left limiting mechanism 3a, rotating gear 41 meshes with the first rotating gear 24. For rotating gear 41 in the right limiting mechanism 3b, rotating gear 41 meshes with the rotating component 26. This allows the two winding mechanisms 4 in the left limiting mechanism 3a and the right limiting mechanism 3b to rotate in opposite directions. The two friction components 32 are the same size, which effectively allows the winding mechanisms 4 on the left limiting mechanism 3a and the right limiting mechanism 3b to rotate at the same speed, thereby ensuring that the winding effect produced by the rotation of the two winding mechanisms 4 is the same.

[0070] Rotating component 42, one end of which is fixedly connected to one side wall of rotating gear 41, and rotating component 42 is located in a fixed groove.

[0071] The other end of the rotating member 42 is fixedly connected to the rotating ring 43, and the rotating ring 43 is movably sleeved in the fixed groove, which effectively ensures the stability of the winding mechanism 4 set on the fixed mechanism 3.

[0072] A shielding roller 44 has one end fixedly connected to the other side wall of the rotating gear 41, and is correspondingly arranged with the rotating component 42. A shielding layer roll is installed on the shielding roller 44, which can pull out the shielding layer strip by rotating itself on the shielding roller 44, and then the shielding layer is wound around the cable core by the rotation of the shielding roller 44 following the rotation of the rotating gear 41. The shielding roller 44 located in the left limiting mechanism 3a is shorter than the shielding roller 44 located in the right limiting mechanism 3b. The wound shielding layer covers the seam of the wound shielding layer located within the left limiting mechanism 3a. The design of the shielding roller 44 allows both the left limiting mechanism 3a and the right limiting mechanism 3b to maintain a certain distance for the winding mechanism 4 above them to perform winding operations. This ensures that the two winding mechanisms 4 can simultaneously and fully wind the cable. At the same time, the design of the two shielding films effectively improves the tightness of the fit between the shielding layer and the cable core, ensuring that the finished cable will not experience increased seam size after multiple bends and rewinds in actual use, thus enhancing the anti-interference effect of the cable. Example

[0073] Based on Example 1, please refer to Figures 3-8 The fixed mechanism 3 also includes:

[0074] Friction component 32, the fixed housing 31 has a frustum groove on one side of the fixing hole, and the fixed housing 31 is fixedly connected to friction component 32 through the frustum groove. Friction component 32 is located on the side of fixed housing 31 near guide roller 12, and the shape of friction component 32 is ring-shaped. For friction component 32 in left limiting mechanism 3a, the material of friction component 32 is a rough sponge with several air holes, which can fully rub the outer wall of the cable core that has just entered the wrapping stage, thereby effectively cleaning the burrs and dust on it. For friction component 32 in right limiting mechanism 3b, the material of friction component 32 is a fine sponge with several air holes, which can compact the outside of the cable after the wrapping operation, further improving the tightness between the shielding layer and the cable core.

[0075] The movable component 33 is fixedly sleeved on the wall of the fixed housing 31 between the fixed hole and the fixed groove. There are twelve sets of movable components 33, evenly arranged around the fixed housing 31. Each movable component 33 consists of a movable tube 331, a fixed ring 332, and a movable plate 333. One end of the movable tube 331, which is biased towards the winding mechanism 4, is connected to the fixed groove, and the other end of the movable tube 331, which is biased towards the friction component 32, is connected to the fixed hole. Therefore, the movable tube 331 is obliquely arranged, and the airflow direction discharged from it is also obliquely arranged, thereby effectively blowing away the impurities remaining in the friction component 32 from the fixed mechanism 3. Both ends are fixedly sleeved with fixed rings 332. Inside the movable tube 331 located between the two fixed rings 332, a movable plate 333 is movably sleeved. The movable plate 333 is connected to the fixed rings 332 by a fixed spring. The movable plate 333 is magnetic. When the winding mechanism 4 approaches the movable component 33, the movable plate 333 can move towards the fixed hole under the action of magnetic repulsion, and then discharge airflow towards the fixed hole, effectively vibrating the friction component 32 and cleaning out the impurities inside. When the winding mechanism 4 moves away from the movable component 33, the movable plate 333 can move towards the fixed groove under the action of the fixed spring, preparing for the movable plate 333 to discharge airflow again.

[0076] Please see Figures 3-5 , Figures 9-10 The winding mechanism 4 also includes:

[0077] The rotating component 42, on the side closest to the movable component 33, has the same magnetism as the movable plate 333, and the rotating component 42 can provide magnetic repulsion for the movable component 33 to release air. Example

[0078] Based on Embodiment 2, a shielding layer covering device for cable processing further includes:

[0079] Please see Figures 3-4 , Figures 11-14The support mechanism 5 is fixedly installed on the top of the placement platform 11 located between the left limiting mechanism 3a and the right limiting mechanism 3b. The support mechanism 5 is used to enhance the stability during the cable wrapping process. The support mechanism 5 consists of a support housing 51 and a liquid storage component 7. The bottom end of the support housing 51 is fixedly connected to the placement platform 11, and the top end of the support housing 51 is provided with a support groove, which can provide space for the installation of the moving component 6 and the liquid storage component 7.

[0080] Please see Figures 11-14 The liquid storage component 7 is located in the support groove of the support housing 51 above the movable component 6. It is used to apply glue to enhance the tightness between the shielding layers. The liquid storage component 7 consists of a liquid storage plate 71 and a rolling shaft 72. The liquid storage plate 71 is fixedly sleeved in the support groove of the support housing 51. The rolling shaft 72 is movably engaged in the support groove above the liquid storage plate 71. The uppermost wall of the rolling shaft 72 is in contact with the cable. The liquid storage plate 71 contains glue, and the initial height of the glue is flush with the middle height of the rolling shaft 72. This effectively ensures that the rolling shaft 72 can apply glue to the outside of the cable with one layer of shielding during rotation, thereby providing tightness between the first and second shielding layers. Example

[0081] Based on Example 3, please refer to Figures 3-5 , Figures 7-8 The fixed mechanism 3 also includes:

[0082] The deformation bladder 34 is fixedly connected to the outer ring of the lower half of the fixing groove of the fixed housing 31. The deformation bladder 34 is made of elastic rubber material and is filled with gas. When the winding mechanism 4 does not squeeze the deformation bladder 34, the deformation bladder 34 is fully in contact with the inner ring of the fixing groove, thus preparing for subsequent extrusion and degassing.

[0083] The fixed trachea 35 has three branches at one end, and the three branches are fixedly connected to the outer wall of the deformation bladder 34, which effectively transfers the gas discharged by the deformation bladder 34 under compression, and avoids the deformation bladder 34 from being damaged by excessive compression.

[0084] Please see Figures 3-5 , Figures 9-10 The winding mechanism 4 also includes:

[0085] The rotating component 42 has a width equal to that of the deformation bladder 34, which enables the rotating component 42 to fully compress the deformation bladder 34. The rotating component 42 is a quarter-circle arc and has a crescent shape. When the rotating component 42 compresses the deformation bladder 34, the shape design of the rotating component 42 can ensure that the rotating component 42 can smoothly compress the deformation bladder 34.

[0086] Please see Figures 11-14 Supporting mechanism 5 also includes:

[0087] The support air pipe 52 is fixedly sleeved on both sides of the support housing 51 below the liquid storage component 7. One end of the support air pipe 52 is connected to the support groove, and the other end of the support air pipe 52 is connected to the upper space of the support housing 51. During the expansion and upward movement of the moving component 6, the air in the support groove can be discharged through the support air pipe 52, thereby generating an upward thrust on the cable located above the support housing 51, and further providing support for the cable.

[0088] Please see Figures 11-14 The movable component 6 is provided at the bottom end of the support groove of the support housing 51 for storing gas from the deformation bladder 34. The movable component 6 includes:

[0089] The movable bladder 61 is made of rubber material that can be vertically stretched and deformed. The upper and lower walls of the movable bladder 61 are connected by a movable spring. The other end of 53 passes through the support shell 51 and is fixedly connected to the movable bladder 61. The bottom end of the movable bladder 61 is fixedly connected to the bottom end of the support groove.

[0090] The top of the movable plate 62 is fixedly connected to the movable bladder 61, thereby discharging the gas squeezed out by the deformation bladder 34 into the movable bladder 61, realizing the expansion of the movable bladder 61, which in turn pushes the movable plate 62 upward and realizes various functions.

[0091] Please see Figures 11-14 The liquid storage assembly 7 also includes:

[0092] The sealing membrane 73 has its top edge fixedly connected to the bottom edge of the liquid storage plate 71. The sealing membrane 73 has a deformation effect and can be slightly lowered by the gravity of the moving hair rod 74.

[0093] The movable bristle rod 74 has one end fixedly connected to the sealing membrane 73, and the other end of the movable bristle rod 74 passes through the liquid reservoir 71 and contacts the rolling shaft 72. The movable bristle rod 74 is made of plastic and can be deflected by the rolling shaft 72. When the movable bladder 61 moves upward, it pushes the sealing membrane 73 and the movable bristle rod 74 upward. When the height of the glue in the liquid reservoir 71 is lower than the minimum height of the rolling shaft 72, the glue adhering to the movable bristle rod 74 can be applied to the outside of the rolling shaft 72, further improving the utilization rate of the glue.

[0094] The working principle of the method of using this invention is as follows:

[0095] When shielding is required, the cable core is first passed through the fixing holes of the left limiting mechanism 3a and the right limiting mechanism 3b and mounted on the two guide rollers 12. At this time, the cable core moves horizontally from left to right under the tension of the winding device (not shown). At the same time, the rotary motor 21 is started, causing the rotating shaft 22 to rotate. Thus, the first rotating gear 24 drives the winding mechanism 4 on the left limiting mechanism 3a to rotate in the forward direction, and the second rotating gear 25 and the rotating part 26 drive the winding mechanism 4 on the right limiting mechanism 3b to rotate in the reverse direction. Thus, the shielding rollers 44 on the two winding mechanisms 4 effectively wrap the shielding layer around the outer wall of the cable core, so that the outer wall of the cable core is wrapped with two shielding layers with opposite winding directions. The outer shielding layer can cover the seam of the inner shielding layer, effectively improving the tightness of the fit between the shielding layer and the cable core. This ensures that the finished cable will not cause the seam to increase after multiple bends and windings in actual use, and enhances the anti-interference effect of the cable.

[0096] During the horizontal movement of the cable core on the working mechanism 1, the friction component 32 in the left limiting mechanism 3a first contacts the cable core, allowing the friction component 32 to fully rub against the outer wall of the cable core, thereby cleaning the burrs and dust attached to the outer wall of the cable core. At the same time, the rotation of the winding mechanism 4 causes the rotating part 42 to intermittently provide magnetic repulsion to the movable plate 333 in the movable component 33, effectively generating a blowing force in the direction of the friction component 32, thereby blowing the friction component 32 to vibrate and expelling the impurities accumulated in the friction component 32 and out of the fixing mechanism 3. The friction component 32 in the right limiting mechanism 3b finally contacts the cable core. At this time, the friction component 32, in conjunction with the airflow, effectively generates a thrust on the shielding layer, further improving the tightness between the shielding layer and the cable core.

[0097] During the horizontal movement of the cable core, the support mechanism 5 can increase the support force on the cable core portion located between the left limiting mechanism 3a and the right limiting mechanism 3b, effectively improving the horizontality of the cable core. This can drive the rolling shaft 72 to roll, thereby applying the glue on the rolling shaft 72 to the cable core that has been wrapped with a shielding layer, thus helping to ensure the tightness of the subsequent connection between the inner and outer shielding layers.

[0098] As the winding mechanism 4 rotates, when the rotating component 42 moves to the deformation bladder 34 area, the rotating component 42 effectively squeezes the deformation bladder 34, causing the gas inside the deformation bladder 34 to be transferred to the moving bladder 61, thereby pushing the moving plate 62 upward, reducing the gap between the moving plate 62 and the liquid storage plate 71, and venting the air between them through the support air tube 52, further providing an upward thrust to the cable, preventing the left limit mechanism 3a and the right limit mechanism 3b from simultaneously winding the cable core downward and affecting the horizontality of the cable core. In addition, when the glue height in the liquid storage plate 71 is lower than the lowest wall height of the rolling shaft 72, the upward movement of the moving bladder 61 can effectively push the sealing film 73 and the moving hair rod 74 upward. The moving hair rod 74 will pick up less glue and come into contact with the rolling shaft 72, thereby applying glue to the outside of the rolling shaft 72, further improving the glue utilization rate.
