Description

Technical Field

[0001] The utility model relates to the technical field of wrapping machines, in particular to an active wire-releasing device of a wrapping machine. Background Art

[0002] During the cable production process, in order to improve the strength and fire resistance of the cable, the cable core needs to be wrapped once or multiple times. The main equipment used for wrapping is the wrapping machine. When the wrapping machine is working, the cable core is wound on the pay-off device. While paying off the wire, the tape is wrapped around the cable core through the rotation of the turntable.

[0003] The pay-off device of the wrapping machine is mainly used to install the cable core reel and support the cable core reel. The pay-off device is usually provided with a lifting device for adjusting the height of the reel. When in use, the reel is lowered for disassembly and replacement, and the reel is raised for normal rotation and pay-off during operation. The Chinese patent document with publication number CN221396537U discloses a pay-off frame for a wrapping machine, including a base plate, a lifting mechanism fixedly connected to the top of the base plate, the lifting mechanism is a cylinder, and lifting plates are slidably fitted at both ends of the lifting mechanism, two support plates are slidably fitted at the top of the base plate, a guide groove is provided on one side of the support plate, and the lifting plate is slidably connected to the adjacent guide groove, a fixing mechanism is provided at one end of the lifting plate, a vertical rod is fixedly connected in the guide groove, one end of the vertical rod passes through the lifting plate and slides with each other, and the lifting plate is limited to slide up and down in the guide groove by the vertical plate. The above solution uses a cylinder to drive the lifting plate to move up and down. The rigidity and strength of the cylinder body are usually poor and cannot withstand large mechanical loads. Especially when the weight of the wire drum is heavy, it is easy to cause the cylinder body to deform or be damaged. At the same time, the vertical rod is also prone to deformation under high load and after long-term use, thereby affecting the sliding of the lifting plate and having poor reliability.

DETAILED DESCRIPTION

[0020] The present invention will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, which only illustrates the basic structure of the present invention in a schematic manner, and therefore only shows the components related to the present invention.

[0021] See also Figures 1-4 The utility model provides an active wire-releasing device for a wrapping machine, comprising a base 10 and a swinging assembly 20, a driving assembly 30 and a tension adjusting assembly 40 all mounted on the base 10. The wire reel is mounted on the swinging assembly 20. The driving assembly 30 is used to drive the swinging assembly 20 to swing, thereby adjusting the height of the wire reel and facilitating the installation and use of the wire reel. The tension adjusting assembly 40 is used to adjust the cable tension released by the wire reel to facilitate adjusting the wire-releasing tension.

[0022] The swing assembly 20 is rotatable relative to the base 10. Specifically, fixed frames 11 are fixedly connected to opposite sides of the upper surface of the base 10. A support base 12 is fixedly mounted on the top of each fixed frame 11. The two support bases 12 are arranged opposite each other, and a fixing pin 13 is fixedly mounted on the support base 12. The swing assembly 20 is rotatably mounted on the fixing pin 13. The swing assembly 20 can deflect and swing around the central axis of the fixing pin 13 to adjust the height of the wire reel on the swing assembly 20. The provision of the support base 12 raises the height of the swing assembly 20, thereby facilitating the lifting of the wire reel to a higher position above the ground and facilitating the rotation of the wire reel.

[0023] The swing assembly 20 includes a swing arm 21, and the wire drum is rotatably mounted on the swing arm 21. In this embodiment, the swing arm 21 is a U-shaped frame structure, and the bottoms of the two opposite sides of the swing arm 21 are rotatably connected to the fixing pin 13.

[0024] To clamp the wire drum onto the swing arm 21, a first plug 22 and a second plug 23 are mounted on either side of the swing arm 21. Both the first and second plugs 22 and 23 are longitudinally oriented, facing each other and coaxially arranged. The wire drum is positioned between the first and second plugs 22 and 23. The first plug 22 is rotatably mounted on the swing arm 21, while the second plug 23 is slidably mounted on the swing arm 21 along its own axial direction. Specifically, a first top cone (not shown) is fixedly attached to the end of the first plug 22, while a second top cone 231 is rotatably mounted to the end of the second plug 23. Both the first and second top cones 231 engage with the center hole of the wire drum, holding the wire drum between them.

[0025] A pushing cylinder 232 is installed on one side of the swing arm 21. The cylinder body of the pushing cylinder 232 is fixedly connected to the swing arm 21. The protruding end of the pushing cylinder 232 is fixedly connected to the second plug 23 through a connecting plate. The output end of the pushing cylinder 232 is parallel to the second plug 23. In this way, when the pushing cylinder 232 is started, the second plug 23 can be driven to move toward or away from the first plug 22 to clamp or release the wire drum.

[0026] In addition, the outside of the first plug 22 is fixedly connected to a fixed disk 221, and a positioning pin 222 is fixedly connected to the fixed disk 221. The positioning pin 222 is coaxial with the first plug 22, and the positioning pin 222 is inserted into a through hole (not shown) on one side of the wire drum. When in use, when the first top cone is inserted into the center hole of the wire drum, the positioning pin 222 is simultaneously inserted into the through hole. In this way, when the first plug 22 rotates, it can drive the wire drum to rotate.

[0027] In this embodiment, a drive motor 24 for driving the first plug 22 to rotate is installed on the swing arm 21. As a preferred embodiment, a wire drum reducer 25 is installed on the swing arm 21. The power input end of the wire drum reducer 25 is connected to the output shaft of the drive motor 24, and the power output end of the wire drum reducer 25 is connected to the first plug 22. In this way, the drive motor 24 drives the first plug 22 to rotate synchronously with the wire drum through the wire drum reducer 25.

[0028] The drive assembly 30 includes a stud 31 rotatable relative to the base 10, a stud motor 32 for driving the stud 31, and a drive block 33 threadedly connected to the stud 31. The drive block 33 is rotatably connected to the swing arm 21. During use, the stud motor 32 is activated, rotating the stud 31, thereby driving the drive block 33 along the axial direction of the stud 31, thereby forcing the swing arm 21 to deflect and swing. Simultaneously, the stud 31 rotates relative to the base 10.

[0029] Specifically, the drive assembly 30 also includes a stud reducer 34. A connecting frame 14 is fixedly mounted on the base 10. A fixed shaft 141 is fixedly mounted on the connecting frame 14. The bottom of the stud reducer 34 is rotatably mounted on the fixed shaft 141. The power input end of the stud reducer 34 is connected to the output shaft of the stud motor 32, and the power output end of the stud reducer 34 is connected to the stud 31. In this way, the stud motor 32 can drive the stud 31 to rotate through the stud reducer 34, and at the same time, the stud 31 can be rotated relative to the base 10. During operation, the stud 31 and the driving block 33 are threadedly connected. When the driving block 33 is moved into position, the driving block 33 has a certain self-locking function, which can effectively prevent the driving block 33 from easily moving along the axial direction of the stud 31, ensuring the stability of the swing arm 21 after position adjustment, and making it more reliable to use.

[0030] As a preferred embodiment, two oppositely arranged connecting plates 211 are fixedly connected to the middle of the swing arm 21, and the driving block 33 is a rectangular block structure. A rotating shaft 331 is protruded on both opposite sides of the driving block 33, and the rotating shaft 331 is rotatably connected to the connecting plate 211.

[0031] The tension adjustment assembly 40 includes a fixed bracket 41, a guide wheel 42, a movable arm 43, and a tensioning pulley 44. The fixed bracket 41 has a "Z"-shaped structure and is fixedly mounted on the base 10. The guide wheel 42 is rotatably mounted on the top of the fixed bracket 41. The movable arm 43 is rotatably mounted on the fixed bracket 41. The tensioning pulley 44 is located below the guide wheel 42 and is rotatably mounted on the movable arm 43. A telescopic member 45 is telescopically provided between the movable arm 43 and the base 10. One end of the telescopic member 45 is hinged to the base 10, and the other end of the telescopic member 45 is hinged to the movable arm 43. During use, the cable released from the cable drum passes around the tensioning pulley 44 and the guide wheel 42 in sequence. By adjusting the length of the telescopic member 45, the position of the tensioning pulley 44 can be adjusted to achieve the cable tension adjustment function.

[0032] In this embodiment, the telescopic member 45 is a tensioning cylinder, the cylinder end of the tensioning cylinder being hinged to the base 10, and the extended end of the tensioning cylinder being hinged to the movable arm 43. In other embodiments, the telescopic member 45 may further include an inner tube and an outer tube movably sleeved on the outer portion of the inner tube, the inner tube and the outer tube being hinged to the base 10 and the movable arm 43, respectively. Once the inner and outer tubes are positioned properly, a locking bolt may be installed on the side wall of the outer tube. Tightening the locking bolt squeezes the inner tube against the outer tube, thereby securing the inner and outer tubes.
