[0026] When it is necessary to screen PC alloy plastic particles of different sizes, rotate the threaded rod 14 to drive the pressing plate 15 to move upward, rotate the movable plate 13, and rotate the pressing plate 15 away from the top of the second frame 4, so that the discharge bin 3 and the sieve plate can be taken out and replaced with a new discharge bin 3 and sieve plate. The reverse operation is performed to fix the discharge bin 3 and the sieve plate on the vibration bin 1, thereby improving the installation and disassembly efficiency of the sieve plate and solving the problem that the sieve plate on the existing vibration screening machine for PC alloy plastic particle production and processing is not easy to disassemble and replace when PC alloy plastic particles of different sizes need to be screened, which brings inconvenience to the use of the equipment.

[0027] Furthermore, a collection bin 7 is fixedly provided at the bottom of the vibration bin 1, and a discharge port is provided at the bottom of the collection bin 7. Vibration motors 10 are fixedly provided on the outer walls of both sides of the vibration bin 1. A drop pipe 8 is fixedly provided on the collection bin 7.

Qualified PC alloy plastic particles fall into the collecting bin 7 through the screening hole 5, and fall into the second receiving box (not shown in the figure) through the discharge port. The larger PC alloy plastic particles remain in the discharge bin 3. At this time, turn the handle and remove the threaded plug 9 from the drop tube 8.

[0032] Furthermore, a reinforcing rod 21 is fixedly connected between the two bottom rods 18. There are two reinforcing rods 21, and the two reinforcing rods 21 are symmetrically distributed about the center line of the bottom rod 18.

[0033] Working principle: When using this vibrating screening machine, pour the PC alloy plastic particles that need to be screened into the discharge bin 3. Since the vibration bin 1 is lifted and supported by the spring 17, after starting the vibration motor 10, it can drive the vibration bin 1 to vibrate well, and finally drive the discharge bin 3 to vibrate. Qualified PC alloy plastic particles fall into the collecting bin 7 through the screening hole 5, and fall into the second receiving box (not shown in the figure) through the discharge port. The larger PC alloy plastic particles remain in the discharge bin 3. At this time, turn the handle and remove the threaded plug 9 from the drop tube 8. The larger PC alloy plastic particles can then fall into the drop tube 8 through the drop hole 6 and finally fall into the first receiving box (not shown in the figure).

[0034] When it is necessary to screen PC alloy plastic particles of different sizes, rotate the threaded rod 14 to drive the pressing plate 15 to move upward, rotate the movable plate 13, and rotate the pressing plate 15 away from the top of the second frame 4. Then, the discharge bin 3 and the sieve plate can be taken out and replaced with a new discharge bin 3 and sieve plate. Reverse the operation to fix the discharge bin 3 and the sieve plate on the vibration bin 1, thereby improving the installation and disassembly efficiency of the sieve plate.
