This utility model provides a multi-type corner bracket feeding unit and a multi-type corner bracket assembly device, relating to the field of corner bracket assembly. The solution includes a base plate and a corner bracket hopper. The corner bracket hopper includes a rack disposed at one end of the base plate, and the rack has at least two storage slots. It also includes a movable base, movably mounted on the base plate, with its movement direction parallel to the arrangement direction of the multiple storage slots. A picking platform is rotatably mounted on the movable base, capable of rotating in a vertical plane. A picking seat is movably mounted on the picking platform, capable of moving along the length of the picking platform. A picking mechanism includes a fixed clamp and a movable clamp, both disposed on the picking seat. The movable clamp can move closer to and further away from the fixed clamp. This utility model can meet the storage and picking requirements of multiple types of corner brackets, satisfying the requirement of installing multiple types of corner brackets on a single profile.

This utility model provides a rotary winch-type integrated crushing, sand making, and shaping machine, including a main frame, an outer rotating cylinder, an inner rotary winch assembly, an outer rotating power mechanism, and an inner rotary winch power mechanism. The outer rotating cylinder is rotatably mounted on the main frame, and the outer rotating power mechanism is mounted on the main frame and used to drive the outer rotating cylinder to rotate. The inner rotary winch assembly is installed inside the outer rotating cylinder, and the inner rotary winch power mechanism is installed at the top of the main frame and used to drive the inner rotary winch assembly to rotate within the outer rotating cylinder. A cylinder liner is provided on the inner wall of the outer rotating cylinder, and several wear-resistant shafts are distributed circumferentially inside the outer rotating cylinder. The inner rotary winch assembly includes a main shaft, multi-layer spiral blades, and material liners. The multi-layer spiral blades are mounted on the main shaft, and the material liners are mounted on each spiral blade. This integrated machine has the advantage of integrating crushing, sand making, and shaping functions into one unit.
