[0002] Polyamide is commonly known as nylon (Nylon), and its English name is Polyamide (PA for short), with a density of 1.15g / cm3. It is a general term for thermoplastic resins containing repeated amide groups - [NHCO] - on the main chain of the molecule, including aliphatic PA, aliphatic-aromatic PA and aromatic PA. Among them, aliphatic PA has many varieties, large output and wide application. Its name is determined by the specific number of carbon atoms in the synthetic monomer.

[0003] The application number is 202120247247.9, which discloses a nylon particle screening machine, including a frame, a screen box mounted on the frame, a screen arranged on the screen box, a driving mechanism installed at the bottom of the screen box to drive the screen box to vibrate, and a buffer spring installed between the frame and the bottom of the screen box; the surface of the screen box is inclined as a whole; it also includes a paving mechanism arranged on the screen for paving materials; the paving mechanism includes a scraper arranged on the screen, a linear module connected to the scraper for driving the scraper to move along the length direction of the screen, and a guide rail arranged on the edge of the length direction of the screen box, and the linear module slides along the guide rail to drive the scraper to move along the length direction of the screen; the screen is arrayed with a plurality of sieve holes, and the corners of the sieve holes are provided with arc surfaces. The utility model can perform multi-stage screening, has good screening effect, does not cause material jamming, has high working efficiency, and has good quality of screened products.

[0004] However, there is a disadvantage that the paving mechanism of the device includes a scraper, and during the paving process, the scraper is likely to squeeze the nylon particles into the screening mesh, causing blockage and reducing the screening efficiency. Utility Model Content

[0012] Furthermore, a vibrator 1 is installed on the outer side wall of the shell, and a vibrator 2 is installed directly below the vibrator 1.

[0013] The utility model has the following beneficial effects:

[0014] (1) The utility model adds a spiral turntable and opens a plurality of screening holes on the spiral turntable. When screening, the nylon particles automatically slide down on the spiral turntable. Since the spiral turntable has a certain rotation inclination angle, which is inconsistent with the gravity direction of the nylon particles, it is not easy to squeeze the nylon particles into the screening holes to cause blockage, thereby improving the screening efficiency.

[0015] (2) The utility model has vibrators 1 and 2 installed on the side wall of the shell. When the inside of the screening hole is clogged, the vibrators are started to vibrate the nylon particles in the screening hole, which is convenient for users.
