The detection assembly 4 is located between the unwinding assembly 2 and the knitting head 3, and includes an inductor 41, a trigger 42, and a first wire passing ring 43. The inductor 41 is arranged on the frame 1; the trigger 41 is movably mounted on the housing of the inductor 41, and is used for triggering the inductor 41; the first wire passing ring 43 is installed on the trigger 42, and is used for pulling the trigger 42 away from the trigger position of the inductor 41 by the braided wire between the unwinding assembly 2 and the knitting head 3. And the auxiliary lower ear wire assembly 5 is used for driving the ear wires woven by the weaving machine head 3 to move downwards.
The working principle of the invention for detecting the broken wire is as follows: the braided wire unreeled by the unreeling component 2 firstly passes through the first wire passing ring 43 on the trigger element 42 and then is transmitted to the braiding machine head 3, at this time, the unreeling component 2 and the braiding machine head 3 tighten the braided wire, and then the trigger element 42 is pulled up from the trigger position of the inductor 41 by the braided wire, so that the inductor 41 is not triggered; when the braided wire wound around the unwinding assembly 2 is broken, the trigger 42 is not pulled by the braided wire and falls back to the trigger position of the sensor 41 to trigger the sensor 41, and at this time, the sensor 41 sends a signal to an industrial control system of the ear wire knitting device, and the industrial control system detects the broken wire.
Further, a first rotating arm 44 is rotatably mounted on the upper portion of the sensor 41, and the trigger 42 is mounted at a free end of the first rotating arm 45; when the first rotating arm 44 is not affected by an external force, the free end of the first rotating arm 44 and the first wire passing ring 43 mounted thereon both rotate around the fixed end of the first rotating arm 44 and descend under the action of self gravity. Meanwhile, the triggering position of the inductor 41 is set at the bottom of the inductor 41 and is located on the circumference of the triggering piece 42 rotating around the fixed end of the first rotating arm 45; therefore, when the braided wire is broken, the trigger 42 falls back and triggers the inductor 41 due to lack of upward pulling force of the braided wire; therefore, the detection assembly 4 has the advantages of simple structure, reasonable design, low cost and the like, and is suitable for large-batch industrial production.
Further, the detecting component 4 further includes a second wire loop 45 and a third wire loop 46; the second wire passing ring 45 and the third wire passing ring 46 are respectively positioned at the top and the middle of the front side of the shell of the inductor 41; in an actual use process, the braided wire unwound by the unwinding assembly 2 sequentially passes through the second wire passing ring 45, the third wire passing ring 46 and the first wire passing ring 43 from top to bottom and then is transmitted to the braiding machine head 2 for braiding operation, so that the braided wire is prevented from interfering with the inductor 41, and the failure rate of the invention is reduced.
Further, the sensor 41 is any one of a photoelectric sensor, a proximity switch, a micro switch, or a touch switch. Specifically, the method comprises the following steps: if the sensor 41 is a photoelectric sensor, when the trigger 42 falls to block infrared light at the lower part of the photoelectric sensor, the photoelectric sensor sends a disconnection signal to an industrial control system; if the sensor 41 is a proximity switch, when the trigger 42 falls to the sensing surface at the bottom of the proximity switch, the proximity switch sends a disconnection signal to an industrial control system; if the sensor 41 is a microswitch, when the trigger 42 falls to touch a switch button at the bottom of the microswitch, the microswitch sends a disconnection signal to an industrial control system; if the sensor 41 is a touch switch, when the trigger 42 falls to touch the touch panel at the bottom of the touch switch, the touch switch sends a disconnection signal to the industrial control system.
