Description

Technical Field

[0001] This utility model relates to the field of cable production technology, specifically to a cable wrapping machine. Background Technology

[0002] A cable wrapping machine is a device that uses a rotating turntable to wrap cable tape around the core wire. It is mainly used in the manufacture of cables, power cables, control cables, and optical cables. By wrapping the cable with insulating material, it isolates the cable conductor from the outside environment, preventing current leakage and short circuits. The wrapping layer can increase the mechanical strength of the cable and protect the conductor and insulation layer inside the cable from damage by external forces during transportation, installation, and use. The cable wrapping machine consists of a pay-off device, a wrapping head, a traction device, and a tension control system. The traction device pulls the cable core forward along the axis at a constant speed, while the wrapping head rotates at high speed, spirally winding the wrapping material around the surface of the cable core at a set angle. The pay-off device automatically adjusts the material release speed based on feedback signals from a tension sensor, ensuring that the wrapping layer is uniformly adhered and wrinkle-free.

[0003] Chinese invention patent CN110610784A discloses a wrapping machine for cable production lines. The wrapping tape roll is installed on the tape feeding shaft. When wrapping the cable core, the tape is guided by the tape feeding roller and then wrapped, which causes the tape to pull on the wrapping tape roll, which can easily cause the wrapping tape roll to fall off, thus affecting the normal progress of the cable core wrapping operation. Therefore, a wrapping machine for cable production is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cable wrapping machine that has the advantage of easily restricting the wrapping tape roll. It solves the problem that when wrapping cable cores, the tape is guided by the tape roller before wrapping, which causes the tape to pull on the wrapping tape roll, easily leading to the wrapping tape roll falling off and affecting the normal progress of the cable core wrapping operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable wrapping machine, comprising a wrapping machine, a wrapping cylinder, and a wrapping disc, characterized in that: the wrapping cylinder yarn tube is provided with a wrapping tape roll, and the wrapping machine is equipped with an anti-detachment structure;

[0006] The anti-detachment structure includes a mounting frame, a connecting column, a Z-shaped bracket, a clamping component, a ball, a limiting plate, a connecting component, and an electric push rod. The mounting frame is fixedly mounted on the wrapping machine, the connecting column is rotatably mounted on the mounting frame, one end of the Z-shaped bracket is fixedly connected to the connecting column, the clamping component is fixedly mounted on the other end of the Z-shaped bracket, the limiting plate is fixedly mounted inside the mounting frame, one end of the connecting component is hinged to the Z-shaped bracket, the electric push rod is fixedly mounted on the mounting frame, and the telescopic end of the electric push rod is hinged to the other end of the connecting component.

[0007] Furthermore, the clamping component includes an annular frame, multiple mounting rods, and multiple rubber rollers. The annular frame is connected to one end of the Z-shaped bracket. The mounting rods are rotatably mounted inside the annular frame. The rubber rollers are fixedly mounted on the outer surface of the mounting rods and are used to compress the wrapping tape roll.

[0008] Furthermore, the wrapping cylinder and the wrapping disc are fixedly connected, the wrapping cylinder is rotatably mounted on the wrapping machine, the wrapping tape roll is mounted on the outer surface of the wrapping cylinder, and the wrapping disc is equipped with guide wheels and tape-pulling rollers.

[0009] Furthermore, another embodiment of the clamping member includes an annular chamber and a ball, the annular chamber being connected to one end of a Z-shaped bracket, and the ball being rotatably mounted inside the annular chamber with one end penetrating through and extending to its exterior.

[0010] Furthermore, two triangular reinforcing blocks are fixedly installed at the corner of the Z-shaped bracket, and a rectangular groove is opened inside the Z-shaped bracket.

[0011] Furthermore, the diameter of the rubber roller near the outer ring is two-thirds of the diameter of the rubber roller near the inner ring, and the rubber roller is frustum-shaped.

[0012] Furthermore, one side of the limiting plate is in close contact with one side of the vertical Z-shaped bracket.

[0013] Furthermore, the connector includes a connecting plate and two support rods, which are rotatably connected to both ends of the connecting plate. The support rods are fixedly installed inside the rectangular groove, and the telescopic end of the electric push rod is rotatably connected to the other support rod.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] This cable wrapping machine features an anti-detachment structure. The clamping components apply continuous pressure through physical contact, effectively preventing the wrapping tape roll from falling off due to centrifugal force or tension changes during high-speed rotation. This reduces downtime for adjustments and improves production continuity. The tapered design of the frustum-shaped rubber rollers adapts to the tapered winding surface of the tape roll, ensuring uniform pressure distribution and preventing local slippage or overpressure damage to the tape. The rolling contact method of the spherical clamping components reduces frictional resistance and is suitable for protecting the surface quality of high-end tapes that are easily scratched. The adjustable structure driven by the electric push rod allows for quick adaptation to wrapping tape rolls of different diameters and widths without the need for manual component replacement, enhancing the equipment's versatility.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figure 1-6 This embodiment of a cable production wrapping machine includes a wrapping machine 1, a wrapping cylinder 2, and a wrapping disc 3. The yarn tube of the wrapping cylinder 2 is provided with a wrapping tape roll 4. The wrapping machine 1 is equipped with an anti-detachment structure 5. The wrapping cylinder 2 and the wrapping disc 3 are fixedly connected. The wrapping cylinder 2 is rotatably mounted on the wrapping machine 1. The wrapping tape roll 4 is mounted on the outer surface of the wrapping cylinder 2. The wrapping disc 3 is equipped with a guide wheel and a tape-pulling roller.

[0025] Example 2: Please refer to Figure 1-6Based on Embodiment 1, the anti-detachment structure 5 includes a mounting frame 51, a connecting column 52, a Z-shaped bracket 53, a clamping member 54, a ball 545, a limiting plate 55, a connecting member 56, and an electric push rod 57. The mounting frame 51 is fixedly mounted on the wrapping machine 1, the connecting column 52 is rotatably mounted on the mounting frame 51, one end of the Z-shaped bracket 53 is fixedly connected to the connecting column 52, the clamping member 54 is fixedly mounted on the other end of the Z-shaped bracket 53, the limiting plate 55 is fixedly mounted inside the mounting frame 51, one end of the connecting member 56 is hinged to the Z-shaped bracket 53, and the electric push rod 57 is fixedly mounted on the mounting frame 51. The telescopic end of the electric push rod 57 is hinged to the other end of the connecting member 56.

[0026] Two triangular reinforcing blocks are fixedly installed at the corner of the Z-shaped bracket 53. A rectangular groove is opened inside the Z-shaped bracket 53. The connector 56 includes a connecting plate and two support rods. The two support rods are rotatably connected to both ends of the connecting plate. The support rods are fixedly installed inside the rectangular groove. The telescopic end of the electric push rod 57 is rotatably connected to another support rod. The triangular reinforcing blocks enhance the structural strength of the Z-shaped bracket and prevent deformation under long-term stress. The rectangular groove provides rotation space for the connector 56 to ensure smooth transmission.

[0027] In addition, one side of the limiting plate 55 is in close contact with one side of the vertical Z-shaped bracket 53. The limiting plate 55 is fixed inside the mounting frame 51. When the Z-shaped bracket is in a vertical position, the limiting plate 55 is in close contact with the side of the bracket, limiting its excessive rotation and ensuring that the pressure of the clamping member 54 is stable within the preset range.

[0028] Using the above technical solution, the electric push rod 57 serves as a power source, driving the connector 56 through telescopic movement. The connector 56 is hinged to the Z-shaped bracket 53. When the electric push rod 57 telescopic, the connector 56 drives the Z-shaped bracket to rotate around the connecting column 52, thereby adjusting the position and angle of the clamping member 54, thus controlling the clamping member 54 to be against one side of the wrapping tape roll 4, thereby preventing the wrapping tape roll 4 from falling off.

[0029] Example 3: Please refer to Figure 1-6 Based on Embodiment 2, the clamping member 54 includes an annular frame 541, multiple mounting rods 542 and multiple rubber rollers 543. The annular frame 541 is connected to one end of the Z-shaped bracket 53. The mounting rods 542 are rotatably mounted inside the annular frame 541. The rubber rollers 543 are fixedly mounted on the outer surface of the mounting rods 542 and are used to squeeze the wrapping tape roll 4.

[0030] In another embodiment, the clamping component 54 includes an annular chamber 544 and a ball 545. The annular chamber 544 is connected to one end of the Z-shaped bracket 53. The ball 545 is rotatably mounted inside the annular chamber 544, with one end extending through and to the outside of it. The ball 545 is partially exposed outside the annular chamber 544 and can rotate freely 360 degrees. It applies pressure to the tape roll through point contact or surface contact, adapts to the dynamic position changes of the tape roll during rotation, and reduces frictional resistance.

[0031] In addition, the diameter of the rubber roller 543 near the outer ring is two-thirds of the diameter of the rubber roller 543 near the inner ring. The rubber roller 543 is truncated cone-shaped. Multiple rubber rollers 543 are truncated cone-shaped, and the diameter gradually decreases from the inside to the outside. They fit against the outer surface of the wrapping tape roll 4. When the Z-shaped bracket rotates, the rubber roller 543 squeezes the tape roll and prevents the tape roll from sliding or falling off on the wrapping shaft cylinder 2 through friction.

[0032] Using the above technical solution, if the clamping element 54 is a rubber roller 543, multiple rubber rollers 543 are frustum-shaped with diameters gradually decreasing from the inside to the outside, and fit against the outer surface of the wrapping tape roll 4. When the Z-shaped bracket rotates, the rubber rollers 543 squeeze the tape roll, and prevent the tape roll from sliding or falling off on the wrapping cylinder 2 through friction. If the clamping element 54 is a ball 545, part of the ball 545 is exposed outside the annular chamber 544 and can rotate freely 360 degrees. Pressure is applied to the tape roll through point contact or surface contact, adapting to the dynamic position changes when the tape roll rotates and reducing frictional resistance.

[0033] The working principle of the above embodiments is as follows:

[0034] In the cable production wrapping machine, the wrapping tape roll 4 is mounted on the wrapping cylinder 2 and rotates with the wrapping cylinder 2 to achieve the wrapping action. The guide wheel and the tape-pulling roller on the wrapping disc 3 assist in guiding and controlling the tension of the wrapping tape.

[0035] The electric push rod 57 serves as a power source, driving the connector 56 through its extension and retraction. The connector 56 is hinged to the Z-shaped bracket 53. When the electric push rod 57 extends or retracts, the connector 56 drives the Z-shaped bracket to rotate around the connecting column 52, thereby adjusting the position and angle of the clamping member 54.

[0036] If the clamping element 54 is a rubber roller 543, multiple rubber rollers 543 are in the shape of a frustum, with the diameter gradually decreasing from the inside to the outside, and they fit against the outer surface of the wrapping tape roll 4. When the Z-shaped bracket rotates, the rubber rollers 543 squeeze the tape roll and prevent the tape roll from sliding or falling off on the wrapping shaft cylinder 2 through friction.

[0037] If the clamping element 54 is a ball 545, part of the ball 545 is exposed outside the annular chamber 544 and can rotate freely 360 degrees. It applies pressure to the strip coil through point contact or surface contact, adapts to the dynamic position change when the strip coil rotates, and reduces frictional resistance.

[0038] The limiting plate 55 is fixed inside the mounting frame 51. When the Z-shaped bracket is in a vertical position, the limiting plate 55 fits tightly against the side of the bracket, limiting its excessive rotation and ensuring that the pressure of the clamping member 54 is stable within the preset range.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
