Description

Technical Field

[0001] The present invention relates to the technical field of cable winding, and in particular to an anti-winding type winding device and method for network jumpers. Background Art

[0002] Before being loaded into a packaging bag or a packaging box, a network jumper needs to be wound into a ring shape to reduce the occupied space of the network jumper and facilitate packaging. At present, most network jumpers adopt a circular winding method. However, the shrinkage degree of the network jumper in the circular winding method is small, so that the network jumper wound in a circle still occupies a relatively large packaging space. Then, larger packaging bags and packaging boxes are required, increasing the cost. Moreover, the relatively large occupied space results in a decrease in the number of network jumpers placed in the same storage space or transportation space. For this reason, an 8-shaped winding method for network jumpers appears, that is, a binding wire is wound in the middle of the jumpers wound in a ring, and the ring-shaped jumpers are shrunk by the binding wire, so that the network jumpers are wound together in an 8-shaped manner, thereby reducing the occupied space of the network jumpers. However, this method will cause the bending degree of both ends of the ring-shaped network jumper to increase, resulting in deformation or whitening of the cable at the bending position, and seriously, the core wire may break. Therefore, how to improve the anti-winding performance of the bent part under the 8-shaped winding of the network jumper is the current key consideration. Summary of the Invention

Detailed implementation method

[0024] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0025] As Figures 1 to 4As shown, a winding device for anti-winding of network jumpers includes a winding workbench 1, on which a winding mechanism and a paper tube feeding mechanism are arranged. The winding mechanism includes a rotating plate 2 and a negative pressure winding roller 3. The rotating plate 2 is rotatably arranged on the winding workbench 1, and the axis of the rotating plate 2 is vertically arranged. Two groups of negative pressure winding rollers 3 are arranged at intervals on the top of the rotating plate 2. A number of negative pressure holes 4 are formed in the side wall of the negative pressure winding roller 3. The paper tube feeding mechanism includes a lifting seat 5, a rotating arm 6 and a paper tube feeding conveyor belt 8. The lifting seat 5 is located between the winding mechanism and the paper tube feeding conveyor belt 8. The lifting seat 5 has a degree of freedom to move axially along the negative pressure winding roller 3. The rotating arm 6 is horizontally arranged and rotatably arranged on the lifting seat 5. The rotation axis of the rotating arm 6 is parallel to the axis of the negative pressure winding roller 3. Two negative pressure clamping rollers 7 are arranged at the bottom of one end of the rotating arm 6. The distance between the two negative pressure clamping rollers 7 is equal to the interval between the two negative pressure winding rollers 3. The negative pressure clamping rollers 7 are used to respectively set two paper tubes on the paper tube feeding conveyor belt 8 on the two negative pressure winding rollers 3. The paper tube feeding conveyor belt 8 conveys the paper tubes to the clamping path of the negative pressure clamping rollers 7. The rotating arm 6 rotates to make the negative pressure clamping rollers 7 located directly above the paper tubes. Then the lifting seat 5 drives the negative pressure clamping rollers 7 to move downwards so that the negative pressure clamping rollers 7 penetrate into the paper tubes. The negative pressure clamping rollers 7 adsorb the paper tubes by negative pressure, so that the negative pressure clamping rollers 7 can clamp the paper tubes without damage. Then the lifting seat 5 resets. The rotating arm 6 rotates to make the negative pressure clamping rollers 7 clamp the paper tubes located directly above the negative pressure winding rollers 3. Then the lifting seat 5 drives the paper tubes to move downwards so that the paper tubes are sleeved on the negative pressure winding rollers 3. Then the negative pressure clamping rollers 7 release the paper tubes so that the paper tubes are completely sleeved on the negative pressure winding rollers 3 under their own gravity. The paper tubes are adsorbed by the negative pressure winding rollers 3 to ensure the stability of the paper tubes. Then the negative pressure clamping rollers 7 reset to clamp the next paper tube. Then the worker winds one end of the network jumper to be wound around the negative pressure winding roller 3. Then the rotating plate 2 drives the negative pressure winding roller 3 to rotate to wind the network jumper around the paper tube. After winding, a binding wire is used on the middle part of the network jumper to bind the annular network jumper into an 8-shaped. Finally, the network jumper is taken off and the above process is repeated to perform 8-shaped winding on the next network jumper. Due to the setting of the paper tubes, when the network jumper is wound in an 8-shaped, the paper tubes will support the bent parts of the cable, preventing the situation that the cable is excessively bent, resulting in damage to the network jumper or breakage of the core wire. While reducing the volume of the network jumper after winding, the anti-winding performance of the network jumper is enhanced, and the situation that the network jumper is damaged by winding is avoided.

[0026] In some embodiments, such as Figure 1As shown, the shape of the lifting seat 5 is in a "U" shape. A main shaft 9 is vertically arranged inside the opening of the lifting seat 5. The main shaft 9 is rotationally connected to the lifting seat 5 through bearings. The rotating arm 6 is eccentrically sleeved on the main shaft 9. The rotating arm 6 is located above the lifting seat 5. The negative pressure clamping roller 7 is arranged at the bottom of the end of the rotating arm 6 away from the main shaft 9. A first motor 20 is arranged at the bottom of the lifting seat 5. The output shaft of the first motor 20 is drivingly connected to the main shaft 9. A first negative pressure pump 10 is arranged inside the opening of the lifting seat 5. The top of the negative pressure clamping roller 7 is connected to the first negative pressure pump 10 through an air pipe 11. A negative pressure cavity is arranged inside the negative pressure clamping roller 7. A plurality of adsorption holes 12 are formed in the side wall of the negative pressure clamping roller 7. The adsorption holes 12 communicate with the negative pressure cavity. The first motor 20 drives the main shaft 9 to rotate, and then drives the rotating arm 6 to rotate through the main shaft 9, so that the rotating arm 6 drives the negative pressure clamping roller 7 to deflect to directly above the output end of the paper tube conveyor belt 8 or deflect to directly above the negative pressure winding roller 3, completing the switching between the feeding operation and the discharging operation of the paper tube. When the negative pressure clamping roller 7 penetrates into the paper tube, the first negative pressure pump 10 generates negative pressure in the negative pressure cavity, and adsorbs the paper tube through the adsorption holes under negative pressure, so that the paper barrel adheres to the negative pressure clamping roller 7, and the negative pressure clamping roller 7 drives the paper tube to move synchronously when it moves, realizing the stable feeding and discharging of the paper tube. A telescopic column 13 is arranged at the bottom of the lifting seat 5. Two ends of the telescopic column 13 are respectively connected to the lifting seat 5 and the winding workbench 1. A spring 14 is sleeved on the telescopic column 13. Two ends of the spring 14 respectively abut against the lifting seat 5 and the winding workbench 1. Lifting cylinders 15 are vertically arranged on both sides of the lifting seat 5. The cylinder bodies of the lifting cylinders 15 are installed on the winding workbench 1. The telescopic shafts of the lifting cylinders 15 are connected to the lifting seat 5 through connecting plates. The lifting seat 5 is driven to move up and down by the telescopic movement of the lifting cylinders 15, so that the lifting seat 5 drives the negative pressure clamping roller 7 to move up and down to adsorb and clamp the paper tube, or place the paper tube on the negative pressure winding roller 3.

[0027] In some embodiments, such as Figure 1 and Figure 4As shown, the paper tube conveyor belt 8 includes a conveyor frame 16, a driving roller 17 and a driven roller 18. The driving roller 17 and the driven roller 18 are both rotatably arranged on the conveyor frame 16. The driving roller 17 is drivingly connected to the driven roller 18 through a belt 19. A second motor 21 is arranged on the conveyor frame 16. A driving gear 22 is arranged on the second motor 21. A gear 23 is arranged at one end of the driving roller 17. The driving gear 22 meshes with the gear 23. A plurality of limiting components are arranged on the belt 19. The plurality of limiting components are arranged at equal intervals along the circumferential direction of the belt 19. The limiting component includes two limiting thin plates 24. The two limiting thin plates 24 are arranged at intervals along the direction perpendicular to the conveying direction of the belt 19. A limiting groove 25 is formed at the top of the limiting thin plate 24. The distance between the two limiting grooves 25 is equal to the distance between the two negative pressure clamping rollers 7. Workers directly place the paper tube in the limiting groove 25, so as to quickly position the paper tube. The second motor 21 drives the driving gear 22 to rotate. The driving gear 22 meshes with the gear 23 to drive the driving roller 17 to rotate. The driving roller 17 drives the driven roller 18 to rotate through the belt 19, realizing the circular transmission of the belt 19. The second motor 21 rotates for a fixed time each time, so that the paper tube can be conveyed directly below the clamping station of the negative pressure clamping roller 7 each time, enabling the paper tube conveyor belt 8 to accurately convey the paper tube.

[0028] In some embodiments, as Figures 1 to 3 shown, a driving cavity 26 is arranged inside the winding workbench 1. A third motor 27 is arranged in the driving cavity 26. The output shaft of the third motor 27 is drivingly connected to a driving shaft 28 through a coupling. The driving shaft 28 is rotatably connected to the winding workbench 1. The top end of the driving shaft 28 is fixedly connected to the bottom of the rotating plate 2. The third motor 27 drives the driving shaft 28 to rotate. The driving shaft 28 drives the rotating plate 2 to rotate. The rotating plate 2 drives the negative pressure winding roller 3 to wind the network jumper. An installation plate 29 is arranged in the driving cavity 26. A second negative pressure pump 30 is arranged on the top of the installation plate 29. A negative pressure pipe 31 is connected to the second negative pressure pump 30. A negative pressure cavity is arranged inside the negative pressure winding roller 3. A negative pressure channel communicating with the negative pressure cavity is arranged on the driving shaft 28 and the rotating plate 2. The negative pressure pipe 31 is connected into the negative pressure channel. The second negative pressure pump 30 is installed on the installation plate 29, and the installation plate 29 is fixedly sleeved on the driving shaft 28, so that the second negative pressure pump 30 rotates together with the driving shaft 28, avoiding the situation that the negative pressure pipe 31 is wound and broken. The second negative pressure pump 30 makes the negative pressure winding roller 3 generate negative pressure to adsorb the paper tube, so that when the negative pressure winding roller 3 winds the network jumper, the paper tube will not break away from the paper tube, ensuring the stability of winding.

[0029] In some embodiments, as Figure 2 and Figure 3As shown in the figure, a limit block 32 is fixed on the drive shaft 28, and a conical lock block 33 is slidably arranged on the inner wall of the drive cavity 26. The limit lock block 33 moves along the radial direction of the drive shaft 28. A conical lock hole 34 is formed on the side wall of the limit block 32. When the third motor 27 stops rotating, the conical lock hole 34 is located on the moving path of the conical lock block 33. A limit groove 35 is formed on the side wall of the winding workbench 1 in the drive cavity 26. A return spring 36 is arranged in the limit groove 35. One end of the conical lock block 33 is slidably fitted in the limit groove 35. The two ends of the return spring 36 are respectively connected to the winding workbench 1 and the conical lock block 33. A push rod cylinder 37 is installed on the side wall of the winding workbench 1. The telescopic shaft of the push rod cylinder 37 is connected to a push rod 38. The push rod 38 movably penetrates into the limit groove 35. When the third motor 27 stops rotating, the negative pressure winding roller 3 stops at the blanking position of the negative pressure clamping roller 7, so that the negative pressure clamping roller 7 can smoothly sleeve the paper tube on the negative pressure winding roller 3. Before sleeving a new paper tube, it is necessary to manually tie the annular network jumper into an 8-shaped loop and remove the wound network jumper. This process is likely to drive the negative pressure winding roller 3 to deflect abnormally, resulting in the negative pressure winding roller 3 being unable to correspond to the paper tube position of the negative pressure clamping roller 7. Therefore, a limit structure is added. When the third motor 27 stops rotating, the push rod cylinder 37 immediately acts, and the push rod cylinder 37 instantly pushes the push rod 38 into the conical lock hole 34, thereby locking the position of the drive shaft 28 and preventing the negative pressure winding roller 3 from deflecting abnormally. After the network jumper is removed, the negative pressure clamping roller 7 sleeves the paper tube on the negative pressure winding roller 3. At this time, the push rod cylinder 37 resets, and the push rod 38 returns to its original position under the action of the return spring 36, so that the push rod 38 disengages from the conical lock block 33. Finally, the third motor 27 drives the negative pressure winding roller 3 to rotate for winding the network jumper, realizing the precise positioning of the negative pressure winding roller 3.

[0030] A method for anti-winding of network jumpers, using the above-mentioned winding device, includes the following steps:

[0031] S1. Paper tube sleeving: Clamp and sleeve two paper tubes on the two negative pressure winding rollers 3 on the paper tube feeding conveyor belt 8 through the paper tube feeding mechanism;

[0032] S2. Cable winding: Use the winding mechanism to wind the cable around the two paper tubes in a ring shape;

[0033] S3. Figure-eight winding: Finally, wind the middle part of the annular cable with a binding wire so that the cable is wound in a figure-eight shape, and use the paper tube to support the bent part of the cable to prevent the bent part of the cable from being bent too much and breaking.

[0034] In summary, by the above method, when the network jumper is wound in an 8-shaped manner, the paper tube will support the bent part of the cable, preventing the network jumper from being damaged due to excessive bending of the cable or the core wire from breaking, reducing the volume of the network jumper after winding, enhancing the anti-winding performance of the network jumper, and avoiding the situation of the network jumper being damaged by winding.
