When it contacts the action block 8, the fixed plate 4 can move downward, and then the fixed plate 4 rises under the action of the No. 1 spring 5 to vibrate. A vibration plate 6 is connected to the lower end of the No. 1 spring 5, and a telescopic rod 16 is connected between the fixed plate 4 and the vibration plate 6. The telescopic rod 16 is used to support the vibration plate 6 and make the vibration plate 6 vibrate only up and down, so that the cam 10 can continuously contact and act on the action block 8.

[0026] A collecting bin 11 is connected to the cooling chamber 1, and the collecting bin 11 extends a certain length to the outer end of the cooling chamber 1. A first inclined surface 12 is connected to the side end of the collecting bin 11, and the first inclined surface 12 is located at the lower end of the cam 10, so that the plastic powder dropped by the workpiece due to vibration will fall onto the first inclined surface 12, and then slide into the collecting bin 11. A second inclined surface 13 is connected to the side end of the first inclined surface 12, and a drop hopper 17 is connected to the side end of the second inclined surface 13. After the workpiece is cooled, the fixing plate 4 is moved to the upper end of the second inclined surface 13, and then the fixation of the workpiece is released, so that the workpiece will fall onto the second inclined surface 13, and then slide into the drop hopper 17. A door curtain 19 is provided at the side end of the cooling chamber 1, and the door curtain 19 is located at the upper end of the drop hopper 17.

[0029] Pull the placement box 14 out of the cooling room 1. At this time, the left side plate 1401 of the placement box 14 is connected to the side plate of the cooling room 1 to prevent the cold air from overflowing. Insert the workpiece on the movable plate 1403 through the connecting ring 1404, and then push the placement box 14 into the cooling room 1. At this time, the right side plate 1402 of the placement box 14 is connected to the side plate of the cooling room 1. Then, the threaded rod 3 is driven to rotate by the No. 2 motor 15 to act on the fixed plate 4 to drive it to move.

[0031] Then start the No. 1 motor 9 to drive the cam 10 to rotate. The raised end of the cam 10 can act on the action block 8 at the side end of the vibration plate 6, so that the vibration plate 6 vibrates up and down with the assistance of the No. 1 spring 5, thereby vibrating the workpiece clamped by the fixing mechanism 7, thereby shaking off the plastic powder adhered to the surface but not fixed, and the fallen plastic powder will fall onto the first inclined surface 12, and then slide into the collection bin 11.

[0032] After the workpiece is cooled, the fixing plate 4 is moved to the upper end of the second inclined surface 13, and then the No. 1 cylinder 706 is retracted so that it no longer acts on the inclined rod 704, so that the moving rod 702 will move under the thrust of the No. 2 spring 703, thereby releasing the clamping rod 705 from fixing the workpiece, and the workpiece will fall onto the second inclined surface 13, then slide into the drop hopper 17 and leave the cooling chamber 1.
