[0027] Reference Figure 1 , Figure 3 and Figure 5This utility model provides an embodiment of a rebar tying machine for building construction, comprising a housing 3, a cover 2 on the top side of the housing 3, a handle 4 fixedly connected to the bottom side of the housing 3, a tying head 1 installed on the left side of the housing 3, which is used to tie tying wire 11 to the intersection of rebars, a wire storage tray 10 connected to the rear side of the housing 3, the outer wall of the wire storage tray 10 being wound with tying wire 11, and a guide roller 12 rotatably connected inside the housing 3, which guides the tying wire 11 into the... In the binding head 1, a motor 9 is installed inside the handle 4. A first gear 15 is fixedly connected to both the drive end of the motor 9 and the front end of the guide roller 12. The two first gears 15 mesh with each other. The motor 9 drives the bottom first gear 15 to rotate, which in turn drives the top first gear 15 to rotate, thus rotating the guide roller 12 and pushing the binding wire 11. An eccentric wheel 13 is connected inside the motor 9. Fixed tubes 20 are fixedly connected to the front and rear sides of the housing 3. (Refer to...) Figure 2 , Figure 6 and Figure 7 Two discs 24 are rotatably connected to both the front and rear ends of the wire storage disc 10. An insert rod 21 is slidably connected inside the fixed tube 20. The insert rod 21 is inserted into the inside of the disc 24. By inserting the insert rod 21 into the disc 24, the disc 24 is fixed in the housing 3, and the wire storage disc 10 is then installed in the housing 3. A limit rod 22 is fixedly connected to the outer wall of the insert rod 21. The limit rod 22 is slidably connected inside the fixed tube 20. The limit rod 22 restricts the insert rod 21 to slide only inside the fixed tube 20 and not rotate. A threaded rod 23 is threadedly connected inside the insert rod 21. The end of the threaded rod 23 is rotatably connected inside the fixed tube 20, and a handle 5 is fixedly connected to the end of the threaded rod 23. The handle 5 is rotatably connected to the end of the fixed tube 20. The threaded rod 23 is rotated by the handle 5, thereby driving the insert rod 21 to slide.

[0028] Reference Figure 1 , Figure 3 and Figure 5 An eccentric wheel 13 has a rotating rod 14 fixedly connected inside. The rotating rod 14 is rotatably connected inside the housing 3. The rotating rod 14 rotates the eccentric wheel 13, thereby adjusting the distance between the eccentric wheel 13 and the guide roller 12. A second gear 6 is fixedly connected to the rear end of the rotating rod 14. A positioning rod 7 is inserted into the rear side of the housing 3. The rotating rod 14 is rotated by the second gear 6, and the positioning rod 7 is inserted into the housing 3, so that the positioning rod 7 is positioned between two adjacent teeth of the second gear 6, thereby fixing the second gear 6. (Refer to...) Figure 3 and Figure 4A telescopic rod 16 is fixedly connected to the top side of the cover 2. A pressing plate 17 is fixedly connected to the top of the telescopic rod 16. The pressing plate 17 can be moved up and down by the telescopic rod 16. A cutting blade 18 is fixedly connected to the bottom side of the pressing plate 17. The cutting blade 18 is slidably connected inside the cover 2 and the housing 3. The cutting blade 18 can be moved up and down by the pressing plate 17, so that the cutting blade 18 can cut the binding wire 11. A spring 19 is sleeved on the outer wall of the telescopic rod 16. The top of the spring 19 is connected to the bottom side of the pressing plate 17, and the bottom of the spring 19 is connected to the top side of the cover 2. The pressing plate 17 is lifted by the spring 19, so that the cutting blade 18 is reset. A guide groove 8 is fixedly connected inside the housing 3. The end of the binding wire 11 passes through the guide roller 12, the guide groove 8 and the housing 3 from left to right.

[0029] Working principle: First, place the wire storage reel 10 with the disc 24 into the machine housing 3, aligning the center of the disc 24 with the center of the fixing tube 20. Then, rotate the handle 5 to rotate the threaded rod 23, causing the insertion rod 21 to slowly slide out of the fixing tube 20 and insert into the disc 24, thus fixing the disc 24 in the machine housing 3. This installs the wire storage reel 10 into the machine housing 3. Next, open the machine cover 2, pull out the end of the binding wire 11 on the wire storage reel 10, and feed it between the guide roller 12 and the eccentric wheel 13. Then, pass it through the guide groove 8 and out of the machine housing 3 to the binding head 1. Next, rotate the second gear 6 to rotate the rotating rod 14, thereby adjusting the distance between the eccentric wheel 13 and the guide roller 12, allowing the eccentric wheel 13 and the guide roller 12 to... The binding wire 11 is clamped, which pushes the binding wire 11 when the guide roller 12 rotates. After adjustment, the positioning rod 7 is inserted into the machine housing 3, so that the positioning rod 7 is located between two adjacent teeth on the second gear 6, thereby fixing the second gear 6. Then the machine cover 2 is closed. When it is necessary to tie the steel bars, the binding head 1 is placed at the intersection of the steel bars, and then the motor 9 is started to drive the first gear 15 on the bottom side to rotate, which in turn drives the first gear 15 on the top side to rotate, thereby causing the guide roller 12 to rotate, so that the guide roller 12 pushes the binding wire 11, and the binding head 1 ties the steel bars. After tying, the pressing plate 17 is pressed to move the cutting blade 18 downward to cut the binding wire 11, so that the binding wire 11 is tied to the steel bars.
