[0016] Second: Through the setting of the limiting unit of the present invention, the cable can be limited by the two pressing wheels.

[0022] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] The present invention provides a wrapping device for cable production by improvement. The technical solution of the present invention is as follows: As Figures 1 to 8 shown, the embodiment of the present invention provides a wrapping device for cable production, including a wrapping machine body 1. A fixed pipe 12 is fixedly connected to the wrapping machine body 1, and a driving turntable 11 is rotatably connected to the wrapping machine body 1. It also includes; A wrapping mechanism, which is located on the fixed pipe 12; The winding mechanism includes an automatic material pressing unit, a limiting unit, and a feeding unit. The automatic material pressing unit includes a second telescopic rod 31 fixedly connected to the inner wall of the fixed pipe 12. A sliding rod 3 is slidably connected to the fixed pipe 12. Arc-shaped pressing plates 32 are fixedly connected to the ends of the sliding rod 3 and the second telescopic rod 31 that are close to each other. Compression springs 33 are sleeved on both the sliding rod 3 and the second telescopic rod 31. The two ends of the compression spring 33 are respectively fixedly connected to the arc-shaped pressing plate 32 and the fixed pipe 12. L-shaped racks 35 are fixedly connected to both arc-shaped pressing plates 32. Two fixed blocks 36 are fixedly connected to the inner wall of the fixed pipe 12. A gear 37 is rotatably connected to the two fixed blocks 36 together. Both L-shaped racks 35 are engaged with the gear 37. A first bevel-edge block 34 is fixedly connected to the top of the sliding rod 3. A fixing plate 26 is provided above the fixed pipe 12. A movable plate 27 is slidably connected to the fixing plate 26. A connecting rod 4 is fixedly connected to the top of the movable plate 27. One end of the connecting rod 4 is fixedly connected to an L-shaped rod 41. A cylindrical rod 42 is fixedly connected to the driving turntable 11. The cylindrical rod 42 is in contact with the L-shaped rod 41. Through the setting of the automatic material pressing unit, when the driving turntable 11 rotates, it drives the fixed column 13 to perform a circular rotation. The rotation of the fixed column 13 drives the rotating rod 14 and the winding tape to rotate, so that the cable can be wound around the winding tape. When the driving turntable 11 rotates, it drives the cylindrical rod 42 to perform a circular rotation. The cylindrical rod 42 drives the L-shaped rod 41, the connecting rod 4, and the movable plate 27 to move. At the same time, the movement of the movable plate 27 squeezes the first bevel-edge block 34 to move downward. The movement of the first bevel-edge block 34 drives the sliding rod 3 and one of the arc-shaped pressing plates 32 to move downward. Through the setting of the gear 37 and the two L-shaped racks 35, the two arc-shaped pressing plates 32 approach each other, so that the cable wound around the winding tape can be pressed tightly, thereby improving the winding effect of the cable.

[0024] Furthermore, a return spring 28 is provided inside the fixing plate 26. The two ends of the return spring 28 are respectively fixedly connected to the fixing plate 26 and the movable plate 27. Through the setting of the return spring 28, when the cylindrical rod 42 moves away from the L-shaped rod 41, the return spring 28 drives the movable plate 27 to reset.

[0025] Further, the limiting unit includes a fixing bracket 2 fixedly connected to the fixing pipe 12. One end of the fixing bracket 2 is fixedly connected with a U-shaped block 21. Two first telescopic rods 22 are fixedly connected to the U-shaped block 21. Pressing wheels 24 are fixedly connected to the ends of the two first telescopic rods 22 close to each other. Compression springs 23 are sleeved on the two first telescopic rods 22. Two ends of the compression springs 23 are respectively fixedly connected to the pressing wheels 24 and the first telescopic rods 22. A sliding bracket 25 is fixedly connected to the pressing wheel 24 located above. The sliding bracket 25 is slidably connected to the U-shaped block 21. One end of the sliding bracket 25 is fixedly connected to the bottom of a fixing plate 26. Through the setting of the limiting unit and the two pressing wheels 24, the cable can be limited. When wrapping a cable with a larger diameter, the distance between the two pressing wheels 24 increases accordingly. The upward movement of the pressing wheels 24 drives the sliding bracket 25 to move. The movement of the sliding bracket 25 drives the fixing plate 26 and the movable plate 27 to move upward. The more the movable plate 27 moves upward, the shorter the downward movement distance of the pressing inclined block 34 is, so that the moving distance of the two arc-shaped pressing plates 32 decreases, thereby being able to automatically adapt to cables of different diameters and improving the pressing effect on the wrapped cable.

[0026] Further, the feeding unit includes a fixing column 13 fixedly connected to the driving turntable 11. A rotating rod 14 is rotatably connected to the fixing column 13. An extrusion plate 16 is sleeved on the rotating rod 14. A compression spring 15 is sleeved on the rotating rod 14. Two ends of the compression spring 15 are respectively fixedly connected to the fixing column 13 and the extrusion plate 16. An installation rod 17 is fixedly connected to the fixing column 13. A circular ring baffle 18 is sleeved on one end of the installation rod 17. A locking bolt 19 is screwed on one end of the installation rod 17. The locking bolt 19 is in contact with the circular ring baffle 18. Through the setting of the feeding unit, when the winding tape in contact with the circular ring baffle 18 is completely wound, the compression spring 15 drives the extrusion plate 16 to drive the pre-placed winding tape to move, and squeezes the sleeve of the wound winding tape out of the circular hole on the circular ring baffle 18, realizing the discharging of the wound winding tape and simultaneously feeding the pre-placed winding tape.

[0027] Further, an installation block 6 is fixedly sleeved on the installation rod 17. A rotating wheel 61 is rotatably connected to the installation block 6. A vibration sensor 62 is fixedly connected to the installation block 6. The bottom end of the vibration sensor 62 is in contact with the rotating wheel 61. A controller 63 is fixedly connected to the winding machine body 1. The controller 63 is electrically connected to the vibration sensor 62 and the driving turntable 11. Through the setting of the vibration sensor 62, the movement of the pre-placed winding tape drives the rotating wheel 61 to rotate. The rotation of the rotating wheel 61 triggers the vibration sensor 62 to transmit to the controller 63 in the form of a wireless signal. The controller 63 turns off the driving turntable 11 and stops conveying the cable at the same time. Then the worker winds one end of the winding tape on the cable again, starts the driving turntable 11 to rotate and conveys the cable at the same time, realizing the convenience for the worker to wind the feeding winding tape on the cable.

[0028] Further, a fixed housing 5 is fixedly sleeved on the fixed pipe 12. The fixed housing 5 is rotatably connected to the driving turntable 11. An air vent groove 56 is formed in the driving turntable 11. An air inlet groove 57 and an air cavity 58 are formed in the fixed column 13. One end of the air inlet groove 57 is communicated with the air cavity 58, the other end of the air inlet groove 57 is communicated with one end of the air vent groove 56, the other end of the air vent groove 56 is communicated with the fixed housing 5. A rubber ring 59 is arranged in the air cavity 58. The rubber ring 59 is sleeved on the rotating rod 14. A movable rod 52 is slidably connected to the fixed housing 5. One end of the movable rod 52 is fixedly connected with an annular piston 51. The annular piston 51 is slidably connected in the fixed housing 5. One end of the movable rod 52 is fixedly connected with an inclined block two 54. An extrusion rod 55 is fixedly connected to the connecting rod 4. The extrusion rod 55 is in contact with the inclined block two 54. A mounting spring 53 is sleeved on the movable rod 52. Two ends of the mounting spring 53 are respectively fixedly connected with the movable rod 52 and the fixed housing 5. Through the arrangement of the annular piston 51, the movement of the movable plate 27 drives the connecting rod 4 and the extrusion rod 55 to move upward. The movement of the extrusion rod 55 extrudes the inclined block two 54, the movable rod 52 and the annular piston 51 to move. The movement of the annular piston 51 drives the gas in the fixed housing 5 to be extruded into the air cavity 58 through the air vent groove 56 and the air inlet groove 57, so that the gas extrudes the rubber ring 59, thereby increasing the friction force between the rubber ring 59 and the rotating rod 14, and further being able to tension the winding tape of the cable winding, improving the cable wrapping effect.

[0029] Specific implementation steps: Install multiple reels on the mounting rod 17, then wind one end of the reel around the cable. Drive the turntable 11 to rotate, which drives the fixed column 13 to rotate in a circle. The rotation of the fixed column 13 drives the rotating rod 14 and the reel to rotate, so that the cable can be wound with the reel. During the winding process of the reel, the reel and the rotating rod 14 rotate automatically. Drive the turntable 11 to rotate to drive the cylindrical rod 42 to rotate in a circle. Every time the cylindrical rod 42 rotates one week, it drives the L-shaped rod 41 to move towards the controller 63. The movement of the L-shaped rod 41 drives the movable plate 27 to move through the connecting rod 4. The movement of the movable plate 27 drives the return spring 28 to stretch and undergo elastic deformation. At the same time, the movable plate 27 moves to squeeze the first bevel block 34 to move downward. The movement of the first bevel block 34 drives the sliding rod 3 and one of the arc-shaped pressing plates 32 to move downward. Through the setting of the gear 37 and the two L-shaped racks 35, the two arc-shaped pressing plates 32 approach each other, so that the cable wound with the reel can be tightened, thereby improving the wrapping effect of the cable. Through the setting of the two pressure wheels 24, the cable can be limited. When wrapping a cable with a larger diameter, the distance between the two pressure wheels 24 increases accordingly. The upward movement of the pressure wheel 24 drives the sliding frame 25 to move. The movement of the sliding frame 25 drives the fixed plate 26 and the movable plate 27 to move upward. The more the movable plate 27 moves upward, the shorter the distance that the first bevel block 34 is squeezed downward, resulting in a reduction in the moving distance of the two arc-shaped pressing plates 32, so that it can automatically adapt to cables of different diameters and improve the pressing effect on the wrapped cable. The movement of the movable plate 27 drives the connecting rod 4 to move upward. The movement of the connecting rod 4 drives the pressing rod 55 to move upward. The movement of the pressing rod 55 squeezes the second bevel block 54 and the movable rod 52 to move. The movement of the movable rod 52 drives the mounting spring 53 to compress and undergo elastic deformation. At the same time, the movement of the movable rod 52 drives the annular piston 51 to move. The movement of the annular piston 51 drives the gas in the fixed shell 5 to be squeezed into the air chamber 58 through the ventilation groove 56 and the air inlet groove 57, so that the gas squeezes the rubber ring 59, thereby increasing the friction between the rubber ring 59 and the rotating rod 14, so that the reel wound around the cable can be tensioned and the wrapping effect of the cable is improved. When the reel in contact with the circular ring baffle 18 is completely wound, the diameter of the sleeve winding the reel is smaller than the inner diameter of the circular ring baffle 18. Since the compression spring 15 is in a compressed state, the compression spring 15 drives the pressing plate 16 to drive the pre-placed reel to move, and squeezes the sleeve winding the reel out of the circular hole on the circular ring baffle 18. The movement of the pre-placed reel drives the runner 61 to rotate. The rotation of the runner 61 triggers the vibration sensor 62 to transmit it to the controller 63 by wireless signal. The controller 63 closes the drive turntable 11 and stops transporting the cable at the same time. The worker winds one end of the reel around the cable again, starts the drive turntable 11 to rotate and transports the cable at the same time, realizing automatic feeding of the reel.
