Raw material feeding device for PLA suction pipe production and using method thereof

Abstract

The invention discloses a raw material feeding device for PLA suction pipe production and a using method thereof. The raw material feeding device comprises a crushing mechanism and a conveying mechanism, the crushing mechanism comprises a fixing plate, the top of the fixing plate is fixedly connected with a crushing box, the top of the crushing box communicates with a feeding hopper, the right end of the front side of the crushing box is fixedly connected with a first driving motor through a supporting plate, an output shaft of the first driving motor is fixedly connected with a first transmission shaft, and the surface of the first transmission shaft is fixedly connected with a first gear. According to the raw material feeding device, the crushing box is used for shielding raw materials when the raw materials are crushed, waste of the raw materials caused by splashing of the raw materials when the raw materials are crushed is avoided, through cooperation of the first driving motor, the first transmission shaft, the first gear, a driven shaft and a second gear, crushing shafts are driven to rotate, granular raw materials can be crushed through opposite rotation of the crushing shafts, and the working efficiency of subsequent processing of the raw materials is improved.

Description

technical field [0001] The invention relates to the technical field of PLA straw processing, in particular to a raw material feeding device for PLA straw production and a use method thereof. Background technique [0002] PLA degradable straws are made of a new type of bio-based and renewable biodegradable material called PLA, also known as polylactic acid, which is proposed using renewable plant resources such as corn and cassava. It is made of starch raw material and is degradable, while ordinary plastic straws are not degradable. Due to the irregularity of the raw materials in the process of producing PLA straws, it is difficult to process them uniformly. At the same time, because most of the raw materials for making PLA straws are It is granular, which also leads to the need to spend a lot of time to melt the raw materials when processing the raw materials in the later stage, thereby reducing the efficiency of making PLA straws. Therefore, a raw material feeding device fo...

Problems solved by technology

[0003] The object of the present invention is to provide a raw material feeding device for the production of PLA straws and its use method, which has the advantage of crushing, and solves the problem that it is difficult to uniformly process the raw materials due to the irregularity of the raw materials in the process of producing PLA straws. At the same time, because most of the raw materials for making PLA straws are granular, this also leads to the need to spend a lot of time melting the raw materials in the later processing of the raw materials, thereby reducing the production efficiency of PLA straws.
