[0002] As time goes by, springs are used in more and more places in life, and the number of springs of different shapes and sizes required has also increased. Spring machines refer to mechanical equipment for producing springs. According to their functional characteristics, they are divided into: compression spring machines, extension spring machines, universal machines, disc machines and special spring machines. They include machine bodies, operating panels and other devices. As far as this type of spring winding machine is concerned, the wire from the wire pulling mechanism moves forward against one or two winding fingers, or against the winding pin, and is turned to the circular track through them and deformed into a spring. The angle of the wire is changed by the pressing force.

[0003] However, currently after the springs are produced by the spring coiling machine, they will fall directly below the discharge port of the spring coiling machine, and then the workers will directly collect them through bags or storage baskets. This will cause the springs to be placed in the storage bags or storage boxes in a messy manner after being formed by the spring coiling machine, which is inconvenient for later sorting and will seriously affect production efficiency.
