Modified PBAT granulation device and preparation method of PBAT foaming material

Abstract

The invention provides a modified PBAT granulation device and a preparation method of a PBAT foaming material, and relates to the technical field of granulation machinery. The device comprises a cooling plate rail. A sieve plate is mounted at the bottom of the right end of the cooling plate rail; a drying device is mounted on a side bracket, a grain cutting device is mounted at the right end of the side bracket, and a reciprocating device is mounted at the outer side of the side bracket; and the mobility of long-strip-shaped raw materials is improved, the situation that the long-strip-shaped raw materials are accumulated in the cooling plate rail, and consequently the conveying passing ability of the long-strip-shaped raw materials is affected is avoided, the grain cutting smoothness and the grain cutting efficiency of the long-strip-shaped raw materials are improved through the grain cutting device, the situation that the raw materials adhere to blades or the front end face of a guide base during grain cutting is avoided through the drying device, the raw materials obtained after grain cutting can be dried, the drying degree of the stored grain cutting materials is improved, the reciprocating device is matched with the sieve plate, prepared raw material grains can be subjected to batch standard screening, and the screening speed is increased, so that the problem that the sieve plate is blocked due to the fact that the prepared raw materials are excessively stacked on the sieve plate is solved.

Description

technical field [0001] The invention belongs to the technical field of granulation machinery, and more specifically relates to a modified PBAT granulation device and a method for preparing foamed materials thereof. Background technique [0002] A granulator is a molding machine used to make materials into a specific particle shape; a granulator on the market generally includes a granulator, an extruder, a cooling mechanism, and a packaging mechanism connected in sequence; After being extruded at the output end of the machine, it enters the cooling mechanism through the conveyor belt for cooling; then it is transported to the packaging mechanism for collection and packaging. [0003] When the existing similar modified PBAT granulation device and its foaming material preparation method are in use, the mobility of the strip-shaped raw materials produced by the extruder is not high, and the strip-shaped raw materials are easy to accumulate in the cooling plate rail. It affects ...

Problems solved by technology

[0004] In order to solve the above-mentioned technical problems, the present invention provides a modified PBAT granulation device and a method for preparing foamed materials thereof, so as to solve the problem that the mobility of the existing strip-shaped raw materials similar to those produced by an extruder is not high, and the strips The accumulation of strip-shaped raw materials in the cooling plate rail will easily affect its transportability, the smoothness and efficiency of pelletizing long strip-shaped raw materials are not good, and the raw materials are easy to stick to the front end of the blade or guide seat during pelletizing. The raw material after granulation is wet, which affects the dryness of the granulated material storage. The prepared raw material granules cannot be screened according to the batch standard. clogging problem
