The upper end of the supporting plate 3 is provided with a guide plate 15, the guide plate 15 is located below the rotating plate 10, the guide plate 15 is arranged opposite to the cylinder 7, and the guide plate 15 can guide the long spring directly screened out from the V-shaped area 16 to the outside of the rack, so as to avoid that the screened out long spring is accumulated in the rack, is stuck and affects the normal rotation of the rotating plate 10.

Under the driving of the conveying belt 12, the long spring rotates in the V-shaped area 16. If the profile of the long spring exceeds the preset range of the measuring instrument 14, it means that the bending degree of the long spring exceeds the range.

Then the cylinder 7 drives the rotating plate 10 to rotate and reset, and the opening and closing passage is closed. The next long spring bending degree detection can be performed. If the profile of the long spring does not exceed the preset range when the long spring rotates, under the action of the forward inclination of the rack, the long spring rotates and slides at the same time, and finally falls out of the gap 17 of the first mounting plate 5 in front of the V-shaped area 16 and is collected.

[0025] The device can automatically fill the long spring from above the rotating plate 10 to the V-shaped area 16 by adding an automatic filling device on one side of the rotating plate 10, so as to realize the automatic replenishment of the long spring.
