[0016] As shown in the figure, the utility model discloses a nail wire conveying mechanism of nailer, including unwinding seat 1, traction assembly and wire reel 14, and the traction assembly drives the nail wire on unwinding seat 1 to be sent to wire reel 14 and then is conveyed to nail gun assembly, wire reel 14 is movably arranged on the frame, and the elastic piece 8 is arranged between wire reel 14 and the frame, and in the embodiment, the elastic piece 8 is spring, and the position sensor is arranged corresponding to wire reel 14, and the position sensor can feed back the position information of wire reel 14 to the controller, and the controller can control the action of traction assembly according to the feedback position information.
[0017] Further, the traction assembly includes first motor 2, and the output end of first motor 2 is connected with traction wheel 4, and the pressing block 3 is arranged corresponding to traction wheel 4, and the nail wire is tightly pressed on traction wheel 4 for traction conveying. By controlling first motor 2 to drive traction wheel 4 to rotate and cooperate with pressing block 3, the traction of nail wire can be realized, and the pressing block 3 is swingably arranged on the frame, when the initial wire is conveyed, the pressing block 3 can be controlled to swing away from the traction wheel, the nail wire is conveniently passed through the pressing block 3 and the traction wheel 4, then the pressing block 3 is controlled to swing and press the nail wire on the traction wheel 4, and then the positioning of the pressing block 3 is realized through fastener or clamping block and other structures.
[0018] Further, the wire winding frame 14 has wire winding portions 9 arranged in a fan shape. With the above structure, the nail wire can be conveniently diverted and pulled.
[0019] Further, the wire winding frame has wire winding wheels 10 arranged thereon, one of the wire winding wheels 10 is connected with a rotating disc 11, the outer wall of the rotating disc 11 is circumferentially provided with protruding teeth 12, and a rotating sensor 13 corresponding to the rotating disc 11 is arranged to be inductively coupled with the protruding teeth 12. With the above structure, when the nail wire moves through the wire winding wheel 10, the wire winding wheel 10 will be rotated by the nail wire, and the wire winding wheel 10 will rotate the rotating disc 11 synchronously, and the rotating sensor 13 can monitor the rotation of the rotating disc 11, and then feedback the real-time pulling speed of the nail wire.
[0020] Further, the position sensor is a first photoelectric sensor 6, and the wire winding frame 14 is provided with a sensing portion 7 for the first photoelectric sensor to sense. When the first photoelectric sensor 6 senses the sensing portion 7 on the wire winding frame 14, it will feedback information to the controller, indicating that the wire winding frame 14 is being pressed and pulled down by the nail wire, and the nail wire is too tight due to insufficient nail wire, and the controller will control the pulling assembly to pull the nail wire, increase the amount of nail wire delivered to the subsequent nail wire, and avoid the nail wire being too tight.

[0023] The working principle of the utility model is: when the nail wire is kept proper tension force to drag and convey, the wire frame 14 will keep high position state under the extrusion of the elastic member 8, if the nail wire is insufficient to lead to the tension force of the nail wire to become big, the nail wire will extrude the wire frame 14 to descend, when the first photoelectric inductor 6 senses the sensing part 7 of the wire frame 14, will feedback information to show that the nail wire is in the situation of too tight, then the controller will control the traction assembly action to increase the traction amount of the nail wire, until the wire frame 14 rises to the first photoelectric inductor 6 cannot sense the wire frame 14, at this time the elastic pressure of the elastic member 8 and the tension degree of the nail wire match, so that the nail wire keeps proper tension degree to convey. If the second photoelectric inductor 5 senses the sensing part 7 of the wire frame 14, then shows that there is no nail wire on the unwinding seat 1, the second photoelectric inductor 5 will feedback information and control mechanism to stop working to change the wire, further improve the safety of use.
