The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.

[0024] Example 1

[0025] like Figs. 1-3 As shown, this embodiment designs a wire feeding system that can control the automatic chain breakage of the chain braiding machine, including components such as a servo wire feeding mechanism 2 and a controller 3.

[0026] The servo wire feeding mechanism 2 is installed on the wire feeding side of the chain braiding machine 1 and is used to feed the metal wire 6 used for chain braiding to the chain braiding machine 1. The servo wire feeding mechanism 2 includes components such as an upper wire feeding wheel 24, a lower wire feeding wheel 25, an upper gear 26, and a lower gear 27.

[0027] The upper wire feeding wheel 24 is located above the lower wire feeding wheel 25, and the two work together to clamp the metal wire 6. When the upper wire feeding wheel 24 and the lower wire feeding wheel 25 rotate, they can move the metal wire 6 to the chain braiding machine 1 for chain link weaving. Both the upper wire feeding wheel 24 and the lower wire feeding wheel 25 can be rubber-coated wheels, thereby increasing the friction between the wire feeding wheel and the metal wire 6.

[0028] The upper wire feeding wheel 24 is coaxially and fixedly connected to the upper gear 26, and the lower wire feeding wheel 25 is coaxially and fixedly connected to the lower gear 27. The upper gear 26 and the lower gear 27 mesh with each other. The lower gear 27 is driven by a servo motor 23, and the motor shaft of the servo motor 23 can be coaxially and fixedly connected to the lower gear 27. When energized, the lower gear 27 can be controlled to rotate, which drives the lower wire feeding wheel 25 to rotate and in turn drives the upper gear 26. The upper gear 26 drives the upper wire feeding wheel 24 to rotate, thereby driving the upper wire feeding wheel 24 and the lower wire feeding wheel 25 through the servo motor 23, thus realizing wire feeding.

[0029] The chain braiding machine 1 is provided with a gear seat 21, which can be a vertical plate perpendicular to the working table plane of the chain braiding machine 1; the shafts between the upper wire feeding wheel 24 and the upper gear 26 and between the lower wire feeding wheel 25 and the lower gear 27 are rotationally connected with the gear seat 21. The upper wire feeding wheel 24 and the upper gear 26 are respectively arranged on opposite sides of the gear seat 21, and the lower wire feeding wheel 25 and the lower gear 27 are respectively arranged on opposite sides of the gear seat 21.

The straightening wheels are divided into vertical straightening wheels 52 and horizontal straightening wheels 53, a plurality of vertical straightening wheels 52 are distributed in a vertical plane in a staggered manner, and a plurality of horizontal straightening wheels 53 are distributed in a horizontal plane in a staggered manner, and the normal direction of the vertical straightening wheels 52 is perpendicular to the normal direction of the horizontal straightening wheels 53.

[0032] The outer side of the chain braiding machine 1 is provided with a control screen, which is in communication connection with the controller 3; the control screen is installed on the front side of the straightening mechanism 5, so as to shield the straightening mechanism 5 by using the control screen and improve the aesthetic appearance.

[0033] The controller 3 can adopt an industrial computer or a PLC, and the controller 3 is connected with the servo motor 23 to control the start-stop and rotating speed of the servo motor 23; when the servo motor 23 stops feeding the wire and the chain braiding machine 1 keeps running, the chain braiding machine 1 will be idling, so that the chain being braided on the chain braiding machine 1 naturally falls off, so that the chain being braided subsequently is not connected with the chain being braided previously, thereby realizing the function of automatic chain breaking in the process of braiding the chain by the chain braiding machine 1.
