Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a plastic pellet sieving mechanism, include sieve case 1 and install sieve case lid 2 on sieve case 1, sieve case 1 is a rectangle box, it is formed by a bottom plate and three side shield splices, install sieve case lid 2 through the hinge rotation on the curb plate of its rear side, sieve case 1's lower fixed surface installs preceding vibrator 3 and back vibrator 4, one-level notch group 7 and second grade notch group 8 have been seted up on sieve case 1's the bottom plate, the below of one-level notch group 7 is provided with small particle size plastic pellet collecting box 9, the below of second grade notch group 8 is provided with conveying mechanism 11, sieve case 1's rear side opening department is provided with large particle size plastic pellet collecting box 10, and fixed mounting has buckle lock 13 on the front side shield of its box, the locked groove of its buckle lock 13 is installed on sieve case lid 2 with the corresponding position department of buckle lock 13 lock body.

Furthermore, a feeding hole 5 is formed in the screen box cover 2, a rectangular notch is formed in the rear side of the feeding hole 5, a transparent plastic film 6 is fixedly glued in the rectangular notch, the screen box cover 2 is arranged, so that plastic particles are prevented from jumping out of the screen box when the vibrator vibrates for screening, and material waste is avoided, and a notch is formed, and a layer of transparent plastic film 6 is glued in the notch, so that a worker can observe the condition in the screen box 1 at any time, and the worker can timely treat the particle clamping phenomenon in the notch in the screen box 1;

furthermore, two front vibrators 3 and two rear vibrators 4 are arranged, the arrangement height of the front vibrators 3 is higher than that of the rear vibrators 4, and the arrangement height of the front vibrators 3 is higher than that of the rear vibrators 4, so that the sieve box 1 is obliquely arranged, plastic particles in the sieve box 1 can well roll downwards along the sieve box 1 when the vibrators work, and the sieving effect is realized;

furthermore, the first-stage notch group 7 and the second-stage notch group 8 are both composed of a plurality of rectangular notches, the width of the notch from front to back in the corresponding notch group is uniformly increased, the width of the last notch in the first-stage notch group 7 is smaller than that of the first notch in the second-stage notch group 8, the width of the notch corresponding to the first-stage notch group 7 and the second-stage notch group 8 on the bottom surface of the sieve 1 is gradually increased from front to back, and therefore when the two notch groups sieve plastic grains, the plastic grains with different grain diameters can more uniformly fall from different notches;
