[0031] Working principle and process:

[0032] The staff directly adds the workpieces of the same batch into the hopper 2, turns on the control switch of the feeding frame 1, and the motor 9 starts to work, controlling the threaded shaft 8 at the end of the main shaft to rotate in the counterclockwise direction, driving the outer lifting slide block 7 to start rising along the threaded shaft 8, and then driving the bracket 6 to rise synchronously. The positioning shaft 4 inside the bracket 6 is connected to the hopper 2 through the fixed block 3, driving it to move upward along the groove of the feeding frame 1. When the hopper 2 moves to the top of the groove, the buckle 10 and the intercepting rod 12 are used to clamp and position the hopper 2, and the right side of the hopper 2 stops rising. As the bracket 6 continues to rise, the positioning shaft 4 will be driven to move along the transverse groove of the bracket 6, and the left side of the control hopper 2 will begin to deflect until the left side of the control hopper 2 is rotated to a position that fits the left side of the loading frame 1, and then the opening of the hopper 2 is aligned with the upper notch of the loading frame 1, and the workpiece inside is dumped onto the platform to complete the loading. Then, the control motor 9 drives the threaded shaft 8 at the end of the spindle to rotate clockwise, and the control bracket 6 begins to descend, and then the hopper 2 is moved and lowered to the bottom of the loading frame 1 to perform the material replenishment operation, thereby improving the loading progress of the workpiece and accelerating the processing progress of the machine tool on the workpiece;

[0033] The workpieces are placed on the platform, and a single workpiece is moved to the position of the push plate 16. The push plate 16 is pressed down, and the arc groove of the push plate 16 disengages from the limit rod 20. The second spring 18 on the left side of the vertical plate 19 pulls the push plate 16 to move downward in the inclined groove of the upper plate 15. The push plate 16 moves on the outside of the guide shaft 17. The push plate 16 can be controlled to press a workpiece and quickly transport it to the unloading inclined plate 13. The workpiece is unloaded and entered into the machine tool for processing. The push plate 16 is pushed back to the left side of the inclined groove of the upper plate 15, and the unloading operation is performed again.
