The bottom of the granulator 1 is provided with a discharge port 101, and the particles are transported into the screening mechanism 3. The screening mechanism 3 adopts multiple particle screening, which can ensure the uniformity of the diameter of the plastic particles, screen out plastic particles of appropriate size, and remove oversized and undersized particles, thereby improving the quality and consistency of the final product and quickly completing the screening of a large number of plastic particles to improve the screening efficiency. The screening mechanism 3 is integrated with the granulator 1, and can also be quickly installed through the installation groove 201, and different types of screen discs can be quickly replaced to adapt to the processing needs of different plastic particles and reduce production downtime.

After the first screen disc 302, the second screen disc 303 and the third screen disc 304 are folded, they are kept flush with the workbench 2, and have two working states of straight screening and inclined screening to meet different production needs.

[0026] The workbench 2 is also provided with an installation groove 201 for connecting a fixing structure 301, the fixing structure 301 includes a group of fixing seats 316, the fixing seats 316 are connected to the installation groove 201, the installation groove 201 is also provided with an installation guide rail, the fixing seats 316 are slidingly arranged on the installation rail, the guide structure 306 includes a group of guide rods 309 connected to the fixing seats 316 and guide seats 311 connected to the guide rods 309, and the guide rods 309 are respectively arranged in the fixing seats 316 and the guide seats 311.

[0027] The cutting and screening are integrated on the workbench 2 in this embodiment. An installation groove 201 is arranged on the upper end face of the side close to the cutting machine 1 of the workbench 2 for installing the screening mechanism 3. The installation groove 201 is provided with an installation guide rail, and a plurality of fixed screw holes with different intervals are arranged on the installation guide rail. The fixed structure 301 connected with the screening mechanism 3 is installed on the installation guide rail. The fixed structure 301 is composed of two fixed seats 316.

[0037] The blocking piece arranged on the end of the guide rod 309 close to the guide base 311 plays a supporting role, and the structure makes the vibration generated by the vibration motor 312 on the third screen disc 304 be transmitted to the first screen disc 302 and the second screen disc 303. At the same time, the end of the guide rod 309 close to the fixed base 316 is also provided with a blocking piece, the blocking piece is directly connected with the shock absorbing spring 315 of the fixed base 316, and the structure can buffer the vibration force, so as to stably connect the fixed base 316 on the workbench 2.

[0039] The cylinder 313 is provided with a push rod, the push rod is connected with a driving lever 318, when the driving lever 318 is lifted under the action of the push rod, the gap between the sieve plates is minimum, until the sieve plates keep flush with the workbench 2.

[0040] Further, the mounting guide rails are transversely arranged in the mounting grooves 201, and a plurality of fixing screw holes are further arranged on the mounting guide rails and the fixing bases 316.

[0041] The fixing bases are mounted through the fixing screw holes on the mounting guide rails, and the distance between the two fixing bases is determined by the model and size of the sieve plates, so that the sieve plates of different models and sizes can be conveniently replaced, and the applicability is higher.
