Problems solved by technology

[0003] In the existing production process, due to the high temperature of the freshly prepared plastic particles, when a large number of plastic particles are screened intensively, it is easy to cause adhesion among the plastic particles and it is difficult to screen; Different particle size screening requirements require different screens for screening, so technicians are required to replace the screens under specific requirements, resulting in problems such as poor flexibility and low work efficiency.

Embodiment 1

[0043] see Figure 1-4 , a plastic particle variable diameter self-screening method, the specific screening method is as follows:

[0044] S1. Firstly, the prepared plastic particles are fed by the feeding cylinder, and cooled by water to prevent the plastic particles from sticking to each other;

[0045] S2, prepare the vibrating screening device 1, the vibrating screening device 1 is provided with a screen 2, the screen 2 is provided with a plurality of inner elastic sieve holes 2023, and the outer sides of the inner elastic sieve holes 2023 are provided with cooling shrinkage materials, According to the particle size requirements of the screened plastic particles, pre-cooling and expanding the pore size of the inner elastic sieve hole 2023;

[0046] S3. Introduce the water-cooled plastic particles in S1 to the screen 2 for sieving treatment. After sieving, the plastic particles that meet the specifications are exported through the conveyor belt 9, and the exported plastic ...

Abstract

The invention discloses a self-screening method for plastic particles with variable diameter, which belongs to the technical field of plastic particle screening. By washing the freshly prepared plastic particles with water, on the one hand, it can effectively prevent the mutual adhesion between plastic particles, and on the other hand, it can effectively reduce the The sieving temperature of the plastic particles is set, and the surrounding material of the inner elastic sieve hole on the sieve is set as a low-temperature shrinkable material. By pre-cooling the sieve, it can meet the requirements of the particle size of the plastic particles to be screened. , pre-cooling and expanding the pore size of the inner elastic sieve hole to improve the screen's suitability for different particle size screening requirements, thereby expanding the scope of application of the screen and eliminating the need for manual replacement of the screen. In addition, after screening, Use the conveyor belt to transport, and dehumidify and dry the water stains on the plastic particles, so as to effectively improve the screening and collection effect of plastic particles.

Description

technical field [0001] The invention relates to the technical field of screening plastic particles, and more specifically, relates to a method for self-screening plastic particles with variable diameters. Background technique [0002] Plastic particles, commonly known as plastic particles, are raw materials for storage, transportation and processing of plastics in the form of semi-finished products. The granulation process of the plastic granulator generally includes: extruder feeding, screw extruder extrusion, cold water tank cooling and drawing, granulator granulation, particle screening, and finished product collection. The granulator cuts the columnar plastic particles into columnar particles with a certain particle size range, and the cut particles are of different sizes, so these plastic particles should be screened. [0003] In the existing production process, due to the high temperature of the freshly prepared plastic particles, when a large number of plastic partic...
