Continuous automatic preparation device for plastic powder

Abstract

The invention discloses a plastic powder continuous automatic preparation device which comprises a vibration mechanism and a multi-stage negative pressure screening mechanism, the multi-stage negative pressure screening mechanism is arranged on the vibration mechanism, and the multi-stage negative pressure screening mechanism comprises a material conveying plate, a material guiding structure and a negative pressure screening structure. According to the plastic powder screening device, the vibrating mechanism is connected with the obliquely-arranged material conveying plate to convey plastic powder, the passing plastic powder is screened for multiple times through negative pressure adsorption through the multiple material guiding structures and the negative pressure screening structure, and it is guaranteed that the plastic powder which does not meet the mesh number requirement in the plastic powder is screened to the tail end of the material conveying plate; the production quality of the plastic powder is further improved due to the fact that the plastic powder is screened for multiple times, and then the plastic powder which does not pass through the negative-pressure screening structure on the material conveying plate is easily separated from the negative-pressure screening structure under the dual action of gravity and the vibration mechanism, so that the negative-pressure screening structure is prevented from being blocked; the plastic powder can be continuously added, and the screening efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of plastic powder production, in particular to a continuous automatic preparation device for plastic powder. Background technique [0002] Plastic powder, also known as plastic ultrafine powder and resin powder plastic, is a synthetic polymer compound, that is, a general plastic or resin, which can freely change its shape and style. Materials, in the production process of plastic powder, in order to ensure the quality of plastic powder, the processed plastic powder is generally filtered to separate the magazines with too large mesh. [0003] The existing method of filtering and separating plastic powder is generally to filter the plastic powder through a filter screen, and use the vibrating motor to generate vibration effect on the filter screen to assist in filtering, so that the plastic powder that meets the mesh number requirement is collected through the filter screen, Other plastic powders with larger ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a continuous automatic preparation device for plastic powder, which solves the problem of clogging of the filter screen pores and the need to add plastic powder multiple times in the existing method of filtering and separating plastic powder with an excessively large mesh size through a vibrating motor vibration filter screen. Separation leads to low efficiency of filtration separation
