Description

Technical Field

[0001] The utility model relates to the technical field of stranding machines, in particular to a wire pay-off rack of a stranding machine. Background Technique

[0002] A stranding machine is a device used to twist multiple metal wires (such as copper wires, aluminum wires) or non-metal wires (such as plastic wires, fiber wires) together according to certain rules, and is widely used in industries such as cable manufacturing, electronic wire harness processing, and rope manufacturing. In order to twist the conductors tightly and orderly into one strand, before stranding, the stranding machine needs to make the conductors have a certain tension through the cooperation of a wire pay-off rack.

[0003] Currently, the existing wire pay-off racks usually have wire pay-off rollers. In order to facilitate inserting wire reels of different sizes onto the wire pay-off rollers, the wire pay-off rollers are usually relatively thin, which may cause the center line of the wire reel to be difficult to coincide with the center of the wire pay-off roller, resulting in the wire reel making an eccentric movement during the process of rotating and paying off the wire, and thus the wire reel will vibrate when paying off the wire, making the wire sometimes too tight and sometimes too loose, causing it difficult for the stranding machine to twist multiple wires tightly and orderly into one strand. Although the wire reel can be fixed on the wire pay-off roller with larger bolts, during the process of paying off the wire, the metal wire may be wound around the bolts, resulting in the breakage of the metal wire. Content of the Utility Model

[0004] The purpose of the utility model is to provide a wire pay-off rack of a stranding machine to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A wire pay-off rack body for placing multiple wire reels, and a chamber is opened inside the wire pay-off rack body;

[0008] A rotating mechanism is arranged inside the wire pay-off rack body and is used to drive the wire reel to rotate.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figures 1 to 6, in the embodiment of the present utility model, a wire pay-off frame of a stranding machine includes a wire pay-off frame body 1 for placing a plurality of wire reels. A chamber 11 is formed inside the wire pay-off frame body 1. A rotating mechanism 2 is arranged inside the wire pay-off frame body 1 for driving the wire reels to rotate. The rotating mechanism 2 includes a plurality of round rollers 21 that are equally spaced and rotatably penetrate through the wire pay-off frame body 1. The round roller 21 is a tubular structure. A plurality of through holes 211 are annularly and equally angularly formed at both ends of the outer wall of the round roller 21. At both ends of the inside of the round roller 21, a plurality of insertion blocks 212 that slide through the through holes 211 at the corresponding positions are annularly and equally angularly arranged. At both ends of the inside of the round roller 21, a spreading component is provided for spreading the plurality of insertion blocks 212 at the corresponding positions. A limiting mechanism 3 is arranged on one side of the wire pay-off frame body 1 for limiting the rotating mechanism 2.

[0032] Specifically, first, the wire reel is sleeved on the round roller 21, and then the plurality of insertion blocks 212 at the corresponding positions are spread by the spreading component, so that the insertion blocks 212 pass through the through holes 211 at the corresponding positions and are in close contact with the inner wall of the wire reel, making the axis of the wire reel coincide with the axis of the round roller 21 at the corresponding position. Then, by rotating the round roller 21, the metal wire on the wire reel can be released, and the end of the released metal wire is passed through the stranding machine. Through the pulling force of the stranding machine and the rotation of the round roller 21, multiple strands of metal wire can be stranded together. This device can make the plurality of insertion blocks 212 at the corresponding positions extend out from the inside of the round roller 21 at the corresponding position through the spreading component, so that the wire reel can be fixed, and the axis of the wire reel can also be made to coincide with the axis of the round roller 21, preventing the wire reel from jumping due to deviation from the axis of the round roller 21 during rotation.

[0033] Embodiment 1

[0034] As Figure 4 and Figure 5 shown, in this embodiment, a connecting block is fixedly connected to one side surface of the insertion block 212. Springs two 213 are fixedly connected between both ends of one side surface of the connecting block and the inner wall of the round roller 21. The spreading component includes a pressing block 215. The pressing block 215 is located inside the round roller 21 at the corresponding position and is slidably connected to the inner wall of the round roller 21. A cylindrical block 216 is fixedly connected to the end of the pressing block 215. A bolt 214 is rotatably connected to the end surface of the pressing block 215 at the corresponding position and is screwed through the end of the round roller 21. The opposite side surfaces of the two pressing blocks 215 are conical structures. The diameter of the cylindrical block 216 is smaller than the diameter of the pressing block 215. A worm gear 22 is fixedly connected to the outer wall of the round roller 21 located inside the chamber 11. A worm 23 that meshes with the plurality of worm gears 22 is rotatably connected between the opposite side surfaces inside the chamber 11. A motor 24 is fixedly connected to one side surface of the wire pay-off frame body 1. The output end of the motor 24 penetrates through the inner side surface of the chamber 11 and is fixedly connected to the worm 23.

[0035] In this embodiment, the corresponding extrusion block 215 can be moved by rotating the bolt 214. Since the diameter of the extrusion block 215 is larger than the diameter of the cylindrical block 216, when the extrusion block 215 moves to the multiple plug blocks 212 at the corresponding positions, the multiple plug blocks 212 can be spread open, thereby fixing the wire drum and aligning the axis of the wire drum with the axis of the round roller 21 at the corresponding position. The worm 23 can drive the multiple worm gears 22 to rotate through the drive of the motor 24, and the rotating worm gear 22 can cause the wire drum to release the metal wire.

[0038] In this embodiment, when the motor 24 is started, the electric push rod 31 is started to drive the arc block 32 to move upward, so that the gear 25 is disengaged from the multiple locking teeth 33. When the motor 24 stops, in order to prevent the worm 23 from rotating due to external factors, the electric push rod 31 can be started to drive the arc block 32 to move downward, so that the gear 25 is engaged with the multiple locking teeth 33, thereby preventing the worm 23 from rotating due to external factors.

[0039] Embodiment 3

[0040] like Figure 2 and Figure 3 As shown, in the present embodiment, a plurality of fixed plates 12 are fixedly connected at equal intervals on one side of the pay-off frame body 1 and located above the round roller 21, a square rod 13 slides through the top surface of the fixed plate 12, a moving block 14 is fixedly connected to the bottom end of the square rod 13, a fixed seat 15 is fixedly connected to the bottom surface of the moving block 14, a pulley 16 is rotatably connected inside the fixed seat 15, a spring 17 is fixedly connected between the moving block 14 and the fixed plate 12 at the corresponding position, and a limiting block 18 is fixedly connected to the top end of the square rod 13.
