Specific embodiments

[0020] 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 creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 6As shown in the figure, an automatic strand threading and cutting device for steel strands includes a bottom plate 1. At one end of the upper surface of the bottom plate 1, there are a motor fixing post 2 and two coil fixing posts 4. Above the motor fixing post 2, there is a driving motor 3. The motor fixing post 2 can provide support and positioning for the driving motor 3. Above the coil fixing post 4, there is a steel strand coil 5. The coil fixing post 4 can provide support and positioning for the steel strand coil 5. The positions of the motor fixing post 2 and the coil fixing post 4 are vertically coaxial. A strand 6 is wound around the steel strand coil 5, and the strand 6 passes through the steel strand coil 5. In the middle of the upper surface of the bottom plate 1, there are a limit device fixing post 7 and a positioning device fixing post 9. Above the limit device fixing post 7, there is a strand limit device 8. The limit device fixing post 7 can provide support and positioning for the strand limit device 8. Inside the upper end of the positioning device fixing post 9, there is a strand positioning device 10. The positioning device fixing post 9 can provide support and positioning for the strand positioning device 10. At the other end of the upper surface of the bottom plate 1, there is a telescopic table 11 and a collection box 13. On the telescopic table 11, there is a cutting device 12. The telescopic table 11 can provide support and positioning for the cutting device 12. The positions of the limit device fixing post 7, the positioning device fixing post 9, the telescopic table 11, and the collection box 13 are horizontally coaxial.

[0022] As Figure 3 shown, the output end of the driving motor 3 is connected to one end of the steel strand coil 5. The steel strand coil 5 rotates on the coil fixing posts 4 at both ends, which can provide stable power for the steel strand coil 5 to rotate, so that the strand 6 can be wound out at a certain speed.

[0023] As Figure 4 shown, the strand limit device 8 includes a limit hopper 801. The limit hopper 801 is hollow to facilitate the strand 6 to penetrate from the entrance of the limit hopper 801. The bottom of the limit hopper 801 is wrapped with buffer cotton 803. Above the limit hopper 801, there is a lubricating liquid tank 802. At the bottom end inside the lubricating liquid tank 802, there is a rectangular hole, and the rectangular hole is connected above the buffer cotton 803. The strand 6 passes through the limit hopper 801, so that the buffer cotton 803 is always soaked with lubricating liquid. On the one hand, the buffer cotton 803 can unload the force on the penetrated strand 6, and on the other hand, it can lubricate the strand 6, reduce the friction generated during the whole operation process, and increase the service life of the device.

[0024] As Figure 5 shown, on the inner surface of the strand positioning device 10, there are three sets of telescopic cylinders 1001 arranged in a circular array. Inside each of the three telescopic cylinders 1001, there is a telescopic rod 1002. At the ends of the telescopic rods 1002, there are positioning balls 1003 embedded. The positioning balls 1003 roll inside the telescopic rods 1002. The strand 6 can pass through the inside of the strand positioning device 10. The telescopic rods 1002 can be adjusted according to the different diameters of the strand 6, so that the three positioning balls 1003 can closely adhere to the strand 6, thus positioning the penetrated strand 6.

[0025] As Figure 5 shown, an infrared ray lamp 1004 is provided below the inner surface of the stranded wire positioning device 10. The infrared ray lamp 1004 can monitor the length of the inserted stranded wire 6 and further control the cutting length.

[0026] As Figure 6 shown, the cutting device 12 includes a cutting base 1201. An electric telescopic device 1202 is provided on the upper surface of the cutting base 1201. A telescopic blade 1203 is provided at the bottom of the electric telescopic device 1202. The telescopic blade 1203 passes through above the cutting base 1201. A cutting pad 1204 is provided in the lower part of the cutting base 1201. A chute block 1205 is provided on one side of the cutting base 1201. A semi-circular slideway is provided in the middle of the chute block 1205. The stranded wire 6 slides into the collection box 13 from the semi-circular slideway, so that the copper wire can be cut off.

[0027] As Figure 6 shown, a fishhook-shaped card slot is provided on the telescopic blade 1203. The stranded wire 6 passes through the fishhook-shaped card slot. The fishhook-shaped card slot can better semi-wrap the copper wire to prevent the copper wire from shifting during cutting. A rectangular blade telescopic opening is provided in the middle of the upper surface of the cutting pad 1204. Semi-circular cutouts are provided through both sides of the cutting pad 1204. The stranded wire 6 passes through the semi-circular cutouts, so that it can cooperate with the telescopic blade 1203 to fully wrap the stranded wire 6 during cutting, making the cutting faster and more accurate.

[0028] When the present utility model is in use, first place the device on a platform. After the staff puts on the steel stranded wire coil 5, insert the copper wire into the stranded wire limiting device 8 and the stranded wire positioning device 10 in sequence. Then adjust the telescopic rod 1002 in the stranded wire positioning device 10 so that the three positioning balls 1003 can closely adhere to the stranded wire 6. Then turn on the drive motor 3 and the infrared ray lamp 1004, and the cutting device 12 waits for cutting. When the stranded wire 6 moves a certain distance, cutting can be performed.
