Description

Technical Field

[0001] This utility model relates to the field of feeding technology, and in particular to a centrifugal screening mechanism for feeding a grinding spring machine. Background Technology

[0002] In modern industrial production, springs are key components widely used in various mechanical and electronic devices, and their processing quality and efficiency are of paramount importance. Spring grinding machines, as crucial equipment for grinding the end faces of springs, rely heavily on their centrifugal feeding and screening mechanisms to enhance overall performance. With the accelerating pace of industrial automation, enterprises are placing higher demands on the production efficiency, precision, and stability of spring grinding machines. This has spurred continuous innovation and optimization of the feeding and screening mechanisms of spring grinding machines to adapt to increasingly fierce market competition and diversified production needs.

[0003] A search revealed Chinese Patent Publication No. CN212600895U, which discloses a spring grinding machine feeding device. The device includes a frame with a servo motor mounted on it. A rotating shaft is connected to the right end of the servo motor, and a fixed rotating disk and a movable rotating disk are rotatably connected to the rotating shaft. The fixed rotating disk is located to the left of the movable rotating disk. Corresponding material receiving grooves are provided on both the fixed and movable rotating disks, and clamping mechanisms are provided on the outside of the receiving grooves. A baffle is provided on the front side of the frame, fitting snugly against the outside of the fixed and movable rotating disks. A feeding box is located at the upper end of the frame, with a feeding channel at the lower end. Grinding mechanisms are located on both sides inside the frame. The springs are fed into the receiving grooves on the rotating disks via the feeding box, and grinding and unloading occur as the rotating disks rotate.
