DETAILED DESCRIPTION

[0014] An intelligent wire feeding and pulling device is composed of four parts: a wire feeding device 1, a connecting device 2, a wire pulling device 3, and an inkjet printer 4. The connecting device 2 is installed at the end of the wire feeding device 1 and the beginning of the wire pulling device 3, the wire 6 passes through the spring 5, and the inkjet printer 4 and the wire pulling device 3 are installed on a wire pulling machine frame 7.

[0015] The wire feeding device 1 can load 4 wire reels at the same time, with two reels in operation and two reels in standby. Each wire reel has the same structure. Open the movable plate 8, put the wire reel on the wire reel fixed wheel 9, and align the wire reel wire nozzle 11 that needs to be operated with the first rotating tube 12 of the connecting device 2 through the up and down movement of the lifting device 10. Start the wire feeding motor 13, drive the first driving shaft 15 to rotate through the wire feeding synchronous belt 14, the first gear 16 on the first driving shaft 15 is engaged with the second gear on the first driven shaft 17, the first driven shaft 17 rotates, and the first driving shaft 15 and the first driven shaft 17 are both equipped with wire feeding wheels (first wire feeding wheel and second wire feeding wheel) to rotate. Relying on friction, the two wire feeding wheels carry the wire 6 entering from the mouth of the wire reel wire nozzle 11 forward, straighten the wire 6, and feed it into the front end of the wire reel wire nozzle 11, and finally enter the first rotating tube 12 of the connecting device 2. During the wire pulling process, the wire reel on the wire reel fixed wheel 9 rotates accordingly.

[0016] When the wire 6 enters the first rotating tube 12 of the connecting device 2, the connecting motor 19 is started, and the transmission is transmitted through the connecting synchronous belt 20. The first rotating tube 12 rotates, driving the spring 5 to rotate, and the connecting motor 19 on the wire pulling device 3 is delayed to start. The second rotating tube 12 rotates. By the action of friction, the wire 6 enters the wire pulling guide tube 21 of the wire pulling device 3 from the second rotating tube 12. When the photoelectric switch 22 detects the wire 6, the wire pulling motor 23 is started, and the encoder 24 installed at the tail of the wire pulling motor 23 starts to record the length of the wire 6. Through the engagement of the third gear 25 and the fourth gear, the first wire pulling wheel 27 and the second wire pulling wheel are driven to rotate to straighten the wire 6. When the wire 6 reaches the set length, the inkjet printer 4 automatically sprays the code and prints the wire number.

[0017] Schematic diagram of wire feeding device Figure 2 , the two wire feeding wheels rotate in opposite directions, carrying the wire 6 forward and straightening the wire 6. The schematic diagram of the wire pulling device is similar.

[0018] When feeding each wire reel for the first time, the wire head needs to be manually fed into the wire reel conductor nozzle 11 and into the wire drawing guide tube 21 of the wire drawing device 3.

[0019] The present invention uses the friction force generated by the rotation of the spring to transmit the wire over a long distance. The flexible connection replaces the complex rigid connection. The present invention automatically sprays the code and prints the wire number at both ends of the wire during the wire transmission process, which is fast and accurate, and does not cause the phenomenon of inconsistent wire numbers at both ends of the wire. The wire is cut to the same length as needed, and no waste is caused. The auxiliary material such as the wire number tube and the processes of printing, cutting, and threading the wire number by a dedicated person are omitted. The present invention is capable of operating with two types of wires at the same time. It is suitable for six wire operations with different diameters from 0.5 square to 2.5 square.
