Abstract
Description
Technical Field
[0001] The utility model relates to a tail line protection device when double-reel wire taking-up and reel changing, in particular to a tail line protection device when double-reel wire taking-up and reel changing. Background Art
[0002] At present, in the design and manufacturing of wire and cable equipment, the core wires of data cables are made by a combination of drawing, annealing, extrusion, cooling, and winding processes. In order to ensure product quality and stability, the production line produces continuously at a set line speed and constant cable tension, and the winding adopts a winding method of double reels automatically switching without stopping. When the production line is running at high speed, when the reel has received the set length of cable, it needs to switch to another empty reel to continue winding. After the reel is changed, the full reel is still rotating at high speed due to inertia, and the cut tail wire ends fly with the reel. The wire ends hit the components or inner walls of the equipment, rebound to the surface of the reel, and damage the core wire on the outer layer of the full reel, and sometimes even affect the winding work of the other reel. A large number of core wires are scrapped. Utility Model Content

[0025] A sprocket pair 6 is arranged on the supporting roller 3 . The sprocket pair 6 is driven by a reduction motor 7 . The edge of the sprocket pair 6 is tangent to the edge of the tail wire guide cover 2 .
[0026] A bearing sleeve 25 is provided at the semicircular surface end of the tail line guide cover 2 and is connected to the supporting bearing 5 via the bearing sleeve 25 .
[0027] The front end of the tail line protection guide semi-cylindrical cover 2 is connected to the frame 1 through the supporting bearing 5, and the rear end of the tail line protection guide semi-cylindrical cover 2 is connected by the supporting roller 3 below and the flexible fulcrum 4 above in a three-point floating manner. The supporting roller 3 and the flexible fulcrum 4 above are respectively fixed to the frame 1, and the tail line protection guide semi-cylindrical cover 2 is coaxially arranged with the take-up drum. The supporting roller 3 is provided with a bearing, and the roller can rotate; the flexible fulcrum 4 is provided with a spring, and the fulcrum can float up and down.
[0028] The reduction motor 7 is fixed to the frame 1, and the sprocket pair 6 consists of a driving sprocket and a passive sprocket. The driving sprocket is installed on the output shaft of the reduction motor 7, and the sprocket pair 6 of the passive sprocket is installed at the front end of the tail wire protection guide semi-cylindrical cover 2. The tail wire protection guide semi-cylindrical cover 2 can be rotated by connecting the transmission through a sleeve roller chain.
[0029] The proximity switch 8 is mounted and fixed on the frame 1, and is used to sense whether the tail line protection guide semi-cylindrical cover 2 is rotated into place.
[0030] The tail wire guide cover 2 has a semi-cylindrical structure 21 .
[0031] A first signaling plate 26 and a second signaling plate 27 are provided on the semicircular surface end, and an end portion of the first signaling plate 26 extends out of the edge of the semicircular surface end.
[0032] The first signaling plate 26 and the second signaling plate 27 are respectively provided with long grooves.
[0033] A proximity switch 8 in contact with the first signaling plate 26 or the second signaling plate 27 is arranged on the frame 1 , a support ring 24 is arranged at the other end of the tail wire guide cover 2 , and a spiral plate 22 is arranged inside the tail wire guide cover 2 .
[0034] A circular ring 23 is disposed inside the supporting ring 24 , a first notch is disposed on the circular ring 23 , and one end of the spiral plate 22 is aligned with the first notch.
[0035] The support ring 24 is connected as a whole by welding; the spiral plate 22 is welded to the rear half of the semi-cylindrical cover 21, and the wire hiding head ring 23 is welded to the rear end of the semi-cylindrical cover 21; a notch is opened on the wire hiding head ring 23, and the spiral plate 22 is aligned with the notch on the wire hiding head ring 23; the support ring 24 is welded to the wire hiding head ring 23 at the rear end.
[0036] The bearing sleeve 25 is screwed to the front end of the semi-cylindrical cover 21, and the first signaling plate 26 and the second signaling plate 27 are screwed to both sides of the front end of the semi-cylindrical cover 21. Long grooves are provided on the first signaling plate 26 and the second signaling plate 27 to adjust the rotation angle of the tail line protection guide semi-cylindrical cover 2. The tail line protection guide semi-cylindrical cover 2 has a bilaterally symmetrical structure and is used for the left and right wire drums respectively.
[0037] In high-speed continuous production, when the wire-reeling length of the wire-reeling reel reaches the set value, the wire-reeling device executes the reel-changing procedure. First, another empty wire reel starts to rotate. After reaching the predetermined speed, the core wire is arranged and moved into the wire-catching area. The wire-catching device hooks the core wire into the wire-catching hook on the empty reel and cuts off the core wire. The wire end at one end remains in the wire-catching hook on the empty reel. At this time, the core wire is switched to the empty reel to continue to be reeled in.
[0038] The thread end at the other end rotates with the full reel, and at the same time, the reduction motor 7 on the full reel side drives the sprocket pair 6 to rotate the tail line protection and guiding semi-cylindrical cover 2 on the full reel side to a certain angle, and the rotation angle is controlled by the signal sending plate 27; after the tail line protection and guiding semi-cylindrical cover 2 on the full reel side rotates, it is located above the full line reel, separating the work of winding up on the other side; at this time, the full reel is still rotating at high speed, and the tail thread end on the full reel falls onto the thread end guiding spiral plate 22, and the centrifugal force of its rotation causes the thread end to slide against the guiding spiral plate 22, and is guided by the guiding spiral plate 22 to the thread head hiding ring 23, and enters the thread head hiding ring 23 through the notch on the thread head hiding ring 23.
[0039] The wire ends are controlled and rotated in the wire end hiding ring 23, which is concentric with the wire drum and located inside the wire drum, thus preventing the wire ends from hitting the equipment components or the inner wall and rebounding to damage the surface core wire of the full wire drum, thus effectively protecting the core wire.
[0040] When the full tray stops rotating, the full tray empty tray procedure is executed, and after the empty tray is installed in place, the tail wire protection guide semi-cylindrical cover 2 is driven by the reduction motor 7 and the sprocket pair 6 to rotate in the opposite direction to the original position, which is controlled by the signaling board 26. The tray changing procedure ends here.
[0041] Fixed in the tangential direction of the wire drum rotation, connected to the wire hiding ring 2. Since the left and right end wire drums are switched with each other, guide plates are installed at both ends of the wire drum. The wire hiding ring 2 is sleeved on the inner side of the wire drum and is concentric with the wire drum. Similarly, since the left and right end wire drums are switched with each other, both wire drums are sleeved with the wire hiding ring 2.
[0042] The two wire drums rotate in opposite directions, and the wire end guide plate 1 and the wire end hiding ring 2 are symmetrical on the left and right sides, ensuring that the wire drums on the left and right ends can switch with each other and both can protect the core wire from being damaged.
[0043] When a full reel switches to another empty reel, the full reel is still rotating at high speed. The tail thread on the full reel falls onto the thread guide plate, and the centrifugal force of its rotation causes the thread to slide against the guide plate.
[0044] The wire ends are guided by the raised edge of the guide plate into the gap of the wire head hiding ring, so that they are guided into the ring. The wire ends rotate in the ring under the state of control, which prevents the wire ends from hitting the equipment parts or the inner wall, rebounding and damaging the surface core wire of the full reel, and effectively achieves the purpose of protecting the core wire.
