Description

Bare copper wire laying protection device

Technical Field

The utility model relates to the technical field of bare copper wire processing, in particular to a bare copper wire pay-off protection device.

Background Art

Bare copper wire is the most basic product among copper wire and cable products. It can be directly used in power, communication, transportation and other departments to transmit electric energy and information. At present, during the production and use of bare copper wire, it is necessary to pay out the rolled bare copper wire to facilitate the processing of bare copper wire. At present, the conventional pay-out operation is to place the rolled bare copper wire on a turntable, and then use the traction equipment to pull the active end of the bare copper wire and pull the turntable to rotate to pay out the wire. However, since the turntable for paying out the bare copper wire is heavy and has a large inertia, when the traction equipment stops pulling, the turntable will continue to rotate under the action of inertia, resulting in excessive pay-out of the bare copper wire, causing entanglement between the bare copper wires.

To this end, the patent document with application number 202321598376.8 discloses a bare copper wire pay-out protection device, which, through the coordinated use of a spring, a first clamp block, a second clamp block, a turntable and other components, enables the winding roller to be stopped at any time during the rotation process, thereby avoiding excessive pay-out of the bare copper wire due to untimely stopping, thereby causing entanglement between the bare copper wires.

However, the device still has the following shortcomings when in use: in order to achieve the separation or engagement between the first card block and the second card block, the staff needs to manually control the push-pull column to operate and move, that is, the stopping and starting of the turntable requires human control. During the operation, the staff needs to stay beside the equipment to prevent missing the optimal stopping control time. The overall use is energy-consuming and there is room for improvement.

To this end, we propose a bare copper wire pay-out protection device to solve the above problems.

Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Please refer to Figures 1-4, a bare copper wire pay-off protection device includes a base frame 1, a tensioning roller 2, a guide wheel 3 and a clamping structure, the tensioning roller 2, the guide wheel 3 and the clamping structure are all installed on the base frame 1, the tensioning roller 2 is located in the upper middle part of the base frame 1, and the guide wheel 3 and the clamping structure are respectively distributed on both sides of the tensioning roller 2, and both ends of the tensioning roller 2 are rotatably connected to a support bar 21, the outer periphery of the support bar 21 is provided with a spring 22, and the bottom end of the support bar 21 passes through the base frame 1, and the two ends of the spring 22 are respectively connected to the protruding bumps on the surface of the support bar 21. The guide wheel 3 is connected to the base frame 1 through a support rod 31, one end of the support rod 31 is rotatably connected to the guide wheel 3, and the other end of the support rod 31 is fixed to the base frame 1, and the support rod 31 is symmetrical about the two ends of the guide wheel 3. The clamping structure includes a movable clamping block 4 and a fixed clamping block 5, which are symmetrically arranged to clamp the rotating drum of the bare copper wire from both ends so that it can follow the movable clamping block 4 and the fixed clamping block 5. The movable clamp block 4 and the fixed clamp block 5 rotate together, and the movable clamp block 4 and the fixed clamp block 5 are supported by the support plate 6. The bottom end of the support plate 6 is fixed to the bottom frame 1. The movable clamp block 4 and the support plate 6 are connected by a screw 41. The screw 41 penetrates the support plate 6 and is threadedly connected thereto. The screw 41 and the movable clamp block 4 are rotatably connected, so that when the screw 41 is turned, the movable clamp block 4 can be driven to move, so as to clamp and fix the rotating drums of different lengths, and facilitate the clamping operation of the rotating drum. The fixed clamp block 5 and The support plates 6 are rotatably connected by a rotating shaft 51, and an extrusion ring 7 is sleeved on the rotating shaft 51. The extrusion ring 7 is located between the support plate 6 and the fixed clamp block 5. A toothed rod 8 is fixed on the side of the extrusion ring 7 away from the fixed clamp block 5. The toothed rod 8 runs through the interior of the support plate 6. Since the toothed rod 8 can be telescopically movable relative to the support plate 6, the extrusion ring 7 can be controlled to approach or move away from the fixed clamp block 5. When the extrusion ring 7 is close to the fixed clamp block 5, the friction between the two is large, thereby forming a rotation resistance, reducing the possibility of the fixed clamp block 5 continuing to rotate.

Please refer to Figure 3. In order to further improve the resistance effect of the extrusion ring 7, the extrusion ring 7 is provided with a magnet block, and a magnetic ring 15 is embedded on the side of the fixed clamp block 5 close to the extrusion ring 7. The opposite surfaces of the magnet block and the magnetic ring 15 attract each other to facilitate magnetic adhesion, thereby increasing the resistance and improving the effect of the extrusion ring 7 in blocking the rotation of the fixed clamp block 5.

Please refer to Figures 2-4. The gear rod 8 and the support bar 21 are linked by a transmission structure. The transmission structure includes a spur gear 1 9 meshed with the lower edge of the gear rod 8 and a spur gear 2 10 meshed with the side edge of the support bar 21. The spur gear 1 9 is rotatably mounted on the outer wall of the support plate 6, and the spur gear 2 10 is rotatably mounted on the bottom surface of the base frame 1. The end of the spur gear 2 10 is coaxially fixed with a bevel gear 11. The outer edge of the bevel gear 11 is meshed with a bevel gear 2 12. The bevel gears 11 are connected to the outer edge of the bevel gear 11. The second 12 is equipped with a pulley 13 through a connecting rod, and the end of the spur gear 9 is also equipped with a pulley 13, and a belt 14 is sleeved between the two pulleys 13. When the bare copper wire is unwinding, its thread end rotates out from the bottom of the drum, passes over the tensioning roller 2, and then passes under the guide wheel 3. At this time, the bare copper wire is pressed on the tensioning roller 2, and the thread end is pulled by other traction equipment. Since the bare copper wire drum is heavy, the bare copper wire is tensioned during normal unwinding when the thread end is pulled, driving the tensioning roller 2 to be stressed. The tension roller 2 is pressed downward by the force, and the tension roller 2 drives the support bar 21 to move downward and compress the spring 22. Under the elastic force of the spring 22, the tension roller 2 keeps the bare copper wire tight. When the traction equipment stops, the bare copper wire drum continues to rotate under the action of inertia. At this time, the bare copper wire is loose, and the tension roller 2 rebounds and moves upward under the elastic force of the spring 22, driving the support bar 21 to move upward. The support bar 21 drives the spur gear 2 10 to rotate, and the spur gear 2 10 drives the bevel gear 1 11 to rotate in the same direction. The bevel gear 11 and the bevel gear 11 rotate in the same direction. Gear 2 12 is meshed, driving bevel gear 2 12 to rotate. Bevel gear 2 12 drives the pulley 13 below to rotate through the connecting rod. The pulley 13 below drives the pulley 13 above to rotate through the belt 14, thereby driving spur gear 1 9 to rotate. Spur gear 1 9 is meshed with the gear bar 8, thereby controlling the gear bar 8 to push the extrusion ring 7 close to the fixed clamp block 5, so that the extrusion ring 7 and the fixed clamp block 5 are tightly attached to increase the friction resistance, thereby preventing the fixed clamp block 5 from continuing to rotate.
