[0053] Reference Figure 3 and Figure 5 The rotating member 600 includes a second motor 610, a disc 620, and a rotating plate 630. The second motor 610 is connected to the end of the piston rod of the first cylinder 130 close to the cylinder 500. The disc 620 is connected to the output shaft of the second motor 610. The central axis of the disc 620 is collinear with the central axis of the cylinder 500. The central axis of the output shaft of the second motor 610 is collinear with the central axis of the disc 620. The length direction of the rotating plate 630 is consistent with the length direction of the cylinder 500. The rotating plate 630 is connected to the disc 620 along one end of its length direction. A slot 540 for the rotating plate 630 to be embedded is provided at the end of the cylinder 500 close to the first cylinder 130. The length direction of the slot 540 is consistent with the length direction of the cylinder 500. When the cylinder is rotated, the rotating plate 630 is embedded in the slot 540.

[0054] When the first cylinder 130 pushes the carrying box 400, the piston rod of the first cylinder 130 extends, and the rotating plate 630 is embedded in the slot 540, and the second motor 610 drives the rotating plate 630 to rotate, thereby driving the cylinder 500 to rotate, and then driving the first locking block 720 away from the first locking groove 122, and the second locking block 523 away from the second locking groove 444, and making the first locking block 720 embedded in the first installation groove 521, and the second locking block 523 embedded in the second locking groove 444, so that the cylinder 500 and the connecting plate 440 pass through the connecting hole, reducing the influence of the first locking block 720 on the movement of the carrying box 400. The first cylinder 130 pushes the cylinder 500 and the carrying box 400 to move back and forth along the length direction of the carrying box 400, thereby shaking the spring, so that the spring distribution is more uniform.

[0055] The implementation principle of the tempering furnace with a feeding device in the embodiment of the present application is as follows: after the feeding assembly 200 inputs a spring into the carrying box 400, the piston rod of the first cylinder 130 extends, the rotating plate 630 approaches the cylinder 500, and the rotating plate 630 is embedded in the slot 540. The second motor 610 drives the disc 620 to rotate, and the rotating plate 630 rotates with the disc 620 and drives the cylinder 500 to rotate. When the cylinder 500 rotates, the first locking block 720 is guided away from the first locking groove 122 by the first guide surface, and at the same time, the second locking block 523 is guided away from the second locking groove 444 by the second guide surface. Because the first column 510 is always embedded in the rotating hole 443, when the second locking block 523 is away from the second locking groove 444, the second locking is squeezed by the inner wall of the rotating hole 443 and embedded in the second installation groove 511, thereby driving the first locking block 720 to be embedded in the first installation groove 521. The first cylinder 130 drives the cylinder 500 and the carrying box 400 to move back and forth along the width direction of the conveyor belt 110, so that the springs in the carrying box 400 shake, thereby making the springs more evenly distributed in the carrying box 400, reducing the stacking of springs, making the springs more evenly heated, and improving the tempering effect.

[0056] After the shaking is completed, the first cylinder 130 drives the carrying box 400 to move and reset, so that one end of the cylinder 500 is embedded in the connecting hole, and the second motor 610 drives the cylinder 500 to rotate, so that the first locking block 720 is close to the first locking groove 122, and the first spring 710 drives the first locking block 720 to be embedded in the first locking groove 122, and the second locking block 523 is close to the second locking groove 444, and the second spring 522 drives the second locking block 523 to be embedded in the second locking groove 444, so that the cylinder 500 is stably connected to the connecting hole. The piston rod of the first cylinder 130 is shortened, so that the rotating plate 630 is away from the cylinder 500, so as to facilitate the conveyor belt 110 to transport the carrying box 400, and during the movement of the carrying box 400, the vibrator 420 vibrates the carrying box 400, so that the springs in the carrying box 400 vibrate, reducing the situation where the springs are entangled with each other.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
