Embodiment 1

[0026] The vibrating screen for plastic particles includes a base and a vibrating screen body. The vibrating screen body includes a screen box 2 with an open top, and the screen box 2 is installed on the base. A vibrating motor is installed on the base, and the vibrating motor is used to drive the screen box 2 to vibrate. A hopper 3 is installed on the top of the sieve box 2, and both the hopper 3 and the sieve box 2 are installed obliquely. The feed cylinder 1 is installed vertically above the high end of the hopper 3, and the low end of the sieve box 2 is provided with a discharge port. Out of the barrel. The bottom of the hopper 3 is provided with several sieve holes. The sieve holes include a first sieve hole 4 and a second sieve hole 8 . The first sieve hole 4 has a smaller aperture than the second sieve hole 8 . The first sieve 4 is used to sieve powder and impurities in the plastic granules, and the second sieve 8 is used to sieve the finished plastic granules. The si...

Embodiment 2

[0038] The difference between this embodiment and Embodiment 1 is that there are several brush strips glued to the bottom of the baffle plate 5. When the baffle plate 5 swings toward the high end of the hopper 3, the brush strips can clean the bottom of the hopper 3, thereby reducing the risk of screen hole clogging. Condition.

Embodiment 3

[0040] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that a balance bar 13 is installed on the hopper 3, the balance bar 13 is arranged across the hopper 3, the left end of the balance bar 13 is sleeved with a wire, and the wire is welded to the screen box 2 superior. The right end of the balance bar 13 is fixed on the hopper 3 through a lock. During use, the balance bar 13 is fastened by the lock to press it against the hopper 3, which can reduce the vibration amplitude of the hopper 3 and prevent the plastic particles in the hopper 3 from splashing due to excessive vibration amplitude.

Abstract

The invention relates to the technical field of plastic processing and particularly relates to a plastic particle vibrating sieve. The plastic particle vibrating sieve comprises a vibrating sieve mainbody, wherein the vibrating sieve main body is connected with a vibrating mechanism used for driving the vibrating sieve main body to vibrate, the vibrating sieve main body comprises a sieve box witha top opening, the top of the sieve box is provided with a hopper, the bottom of the hopper is provided with a plurality of sieve holes, both the hopper and the sieve box are obliquely arranged, andthe low end of the sieve box is provided with a discharging opening; and baffles used for guiding plastic particles to move in a wavy path are arranged on the side wall of the hopper from the high endto the low end in a staggered manner. The problem of poor plastic particle sieving effect in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of plastic processing, in particular to a vibrating screen for plastic particles. Background technique [0002] Plastic granules, that is, granular plastics, can be further processed into various plastic products. Plastic granules are usually prepared by mixing plastic raw materials and various masterbatches, melting them, and then extruding them through an extruder. The prepared plastic particles need to be screened to remove particles that do not meet the particle size requirements. [0003] In the prior art, plastic particles are mostly screened by vibrating screens. The vibrating screens are installed obliquely. Plastic particles move from the high-end of the vibrating screen to the discharge port of the low-end through vibration. During the movement, they are screened through the screen holes. Plastic particles stay on the vibrating screen for a short time, especially when there are many materials, it...
