[0001] The present invention relates to the technical field of cable production equipment, and particularly relates to a wire pay-off machine for cable production with quick-release replacement. Background Art

[0002] When producing automotive cables, data cables, etc., the cables are first produced in rolls, and then cut according to different cable specifications and lengths, and then components such as structures are installed. This makes it necessary to pay off the wire reel through a pay-off machine and feed it into subsequent processing equipment during the actual production process. There is a type of pay-off machine that mounts the wire reel by short shafts at both ends and drives it to rotate for pay-off. This type of pay-off machine is prone to the problem of the wire reel slipping during rotation due to the lack of support for the middle section of the wire reel. There is also a long-shaft pay-off machine that can mount the wire reel by passing a long through-shaft through the wire reel, thereby ensuring sufficient support for the wire reel and effectively avoiding the wire reel from slipping. However, its operation is complicated when removing the empty wire reel and installing the full wire reel. It is necessary to completely remove and move the fixing part at one end. Moreover, both of the above two types of pay-off machines need to install corresponding specifications of claws to adapt to different wire reels, resulting in certain limitations in the use of the above pay-off machines.

The rear support frame 3-4 is fixed to the base of the rear three-claw clamp 1, and the lower end is hinged to the pitch adjustment mechanism 4 through a rotating shaft; Specific structure of the pitch adjustment mechanism 4 The pitch adjustment mechanism 4 is used to adjust the pitch angle of the rear support frame 3-4, including: The lifting frame 4-1 is located below the rear support frame 3-4, and the upper end is hinged to the rear support frame 3-4 through a rotating shaft; The lifting hydraulic rod 4-2 is vertically fixed on the stepping frame 5-15-1, and its output end is fixed to the bottom of the lifting frame 4-1, and is used to drive the lifting frame 4-1 to lift vertically; The pressure shaft 4-3 passes through the lifting frame 4-1 horizontally through the bearing, and the two ends are fixed to support the hydraulic rod 4-4; The supporting hydraulic rod 4-4 is arranged horizontally, one end of which is hinged to the pressure-bearing shaft 4-3, and the other end is hinged to the side of the rear support frame 3-4, and the rear support frame 3-4 is controlled to be erected or laid flat by telescoping; Specific structure of the opening and closing adjustment mechanism 5 The opening and closing adjustment mechanism 5 is used to control the distance between the front and rear three-claw clamping jaws 1, and includes: The stepping frame 5-15-1 is located below the lifting frame 4-1, and the lifting hydraulic rod 4-2 is fixed thereon; Guide rods 5-2, two guide rods 5-2 are horizontally fixed to the front end of the stepping frame 5-15-1, and the extension direction is consistent with the opening and closing direction of the three-claw clamping claw 1; The guide sleeve 5-3 is fixed to the rear end of the front support frame 2-4, and is sleeved outside the guide rod 5-2 and can slide along it; The stepping hydraulic rod 5-4 is horizontally fixed on the stepping frame 5-15-1, and the output end is connected to the guide sleeve 5-3, and pushes the front and rear three-claw clamping claws 1 to move closer or apart through telescoping; Also available: Panel 6 and guide groove 7, the bases of the front and rear three-claw clamping claws 1 are fixed with panel 6, and arc-shaped guide groove 7 is provided on the panel 6; the front support shaft 2-1 and the rear support shaft 3-1 are respectively arranged in the guide groove 7 of the front and rear panels 6, and can slide in the groove to adapt to the opening action of the three-claw clamping claw 1; The spline shaft 8 and the spline sleeve 9. The front end of the rear support shaft 3-1 fixes the spline shaft 8. The spline sleeve 9 is slidably sleeved on the spline shaft 8. The threaded rod 3-3 is fixed to the front end of the spline sleeve 9. The spline sleeve 9 can axially slide along the spline shaft 8 and transmit rotational power at the same time. The spring 10 and the limit ring 11. The spring 10 is sleeved on the spline shaft 8. The two ends of the spring respectively abut against the rear support shaft 3-1 and the spline sleeve 9. The limit ring 11 is fixed to the rear end of the spline sleeve 9, and its outer diameter is larger than the inner diameter of the threaded sleeve 2-3, which is used to limit the insertion depth of the threaded rod 3-3.

[0025] When using this device, when the threaded rod 3-3 and the threaded sleeve 2-3 are in a connected state, first, the servo motor 3-2 drives the rear support shaft 3-1 to rotate, thereby driving the spline shaft 8 to rotate. Then, through the transmission of the spline sleeve 9, the threaded rod 3-3 is driven to rotate, so that the rotation of the threaded rod 3-3 is screwed out of the threaded sleeve 2-3 and disengaged. Then, the stepping hydraulic rod 5-4 is used to push the stepping frame 5-1 to slide towards the end far from the front support frame 2-4. Further, the stepping frame 5-1 drives the guide rod 5-2 to slide in the guide sleeve 5-3, so that the front and rear three-jaw chucks 1 move away from each other. Then, the lifting hydraulic rod 4-2 drives the lifting frame 4-1 to descend, and the support hydraulic rod 4-4 drives the rear support frame 3-4 to rotate and lie flat. After the rear support frame 3-4 lies flat, the rear support shaft 3-1 rotates to be vertically upward. Then, the wire reel of the cable is sleeved on the three front support shafts 2-1 on the front three-jaw chuck 1. At this time, the three front support shafts 2-1 and the rollers 2-2 thereon are all placed inside the wire reel. Then, the support hydraulic rod 4-4 is used to push the rear support frame 3-4 to stand up and make the rear support shaft 3-1 lie flat. The lifting hydraulic rod 4-2 is used to push the lifting frame 4-1 upward, thereby driving the rear support frame 3-4 to rise, so that the front and rear three-jaw chucks 1 are horizontally aligned. Further, the threaded rod 3-3 and the threaded sleeve 2-3 are aligned. Then, the stepping hydraulic rod 5-4 drives the stepping frame 5-1 to move forward, so that the front and rear three-jaw chucks 1 approach each other, so that the threaded rod 3-3 is inserted into the rear port of the threaded sleeve 2-3. And as the stepping frame 5-1 continues to move forward, the threaded sleeve 2-3 abuts against the threaded rod 3-3, and then pushes the spline sleeve 9 to move backward on the spline shaft 8 and compress the spring 10. Then, the servo motor 3-2 drives the rear support shaft 3-1 to rotate, thereby driving the rotation of the roadworn, and screwing the threaded rod 3-3 tightly in the threaded sleeve 2-3. Then, the claw teeth of the front and rear three-jaw chucks 1 are simultaneously controlled to open, so that the front support shaft 2-1 and the rear support shaft 3-1 move and open synchronously, and further the roller 2-2 abuts against the inner wall of the wire reel to support the wire reel, so that the wire reel rotates on the roller 2-2 during wire release.

[0026] Compared with the prior art, the beneficial effects of the present invention are 1. By arranging two three-jaw chucks 1 at the front and the back and attaching a roller 2-2 to the front support shaft 2-1, the device can hold the wire reel by opening the roller 2-2, so as to hold the wire reel and facilitate the rotation and wire release of the wire reel. 2. The device arranges the rear support frame 3-4 on the stepping frame 5-1, and arranges the rear support frame 3-4 through the lifting frame 4-1. Furthermore, the support hydraulic rod 4-4 and the lifting hydraulic rod 4-2 are arranged in cooperation with the lifting frame 4-1, and the stepping hydraulic rod 5-4 is arranged in cooperation with the stepping frame 5-1, so as to realize the movement and rotation of the three-jaw chuck 1 at the rear side, and realize the opening and closing of the threaded rod 3-3 on the rear support shaft 3-1 and the threaded sleeve 2-3 on the front support shaft 2-1, so as to facilitate the quick disassembly of the wire reel.
