Description

Technical Field

[0001] The utility model relates to the technical field of particle screening machines, in particular to a recycled plastic particle screening machine. Background Art

[0002] Recycled plastic particles are granular substances processed from waste plastics, mainly using discarded plastic products as raw materials. The production and use of recycled plastic particles has the effect of improving the utilization rate of waste resources and is conducive to achieving environmental protection. When producing and preparing recycled plastic particles, due to the different sizes of the prepared recycled plastic particles, in order to make the size of the plastic particles in the same batch remain relatively more uniform, the recycled plastic particles are usually screened at this time. When performing the screening operation, the corresponding screening machine is usually used.

[0003] There are many types of screening machines on the market. Most of them can only screen plastic particles of a single size and cannot perform screening operations for multiple sizes and specifications. Some screening machines can complete screening operations for multiple sizes and specifications, but the internal cylindrical parts generally use valves to control the opening and closing operations to achieve the effect of controlling the retention time of the raw materials in each screening part. When manual valves are used for control operations, manual operation is still required. If electric valves are used for control operations, wiring operations are also required. The entanglement of cables will affect the normal screening operation and bring inconvenience to users. In view of this, we propose a recycled plastic particle screening machine.

[0028] In this embodiment, the outer cylinder 1 is set to be tilted downward by 45° to 60° for the downward rolling operation of the particles, so that the particles can roll downward more smoothly along the first mesh cylinder 16, the second mesh cylinder 161, the third mesh cylinder 162 and the fourth mesh cylinder 163 in sequence.

[0029] Specifically, the first mesh tube 16 is fixedly installed at the end of the end tube 14, and the fourth mesh tube 163 is fixedly installed at the end of the lower discharge tube 15.
