Description

Technical Field

[0001] The utility model belongs to the technical field of cup manufacturing and relates to a raw material stirring device, in particular to a raw material stirring device for PLA cup production. Background Art

[0002] PLA, a biodegradable polymer derived from renewable resources such as corn starch or sugar cane, has emerged as a promising material for making disposable cups. The main advantage of PLA is its biodegradability, which means that it can naturally break down into non-toxic elements when exposed to the right conditions, significantly reducing its impact on the environment.

[0003] PLA raw material mixer is a kind of equipment which uses the principle of rapid rotation to achieve the purpose of uniform mixing. It is widely used in the mixing of PLA flakes, crushed materials, plastic particles, new and old PLA raw materials and adding masterbatch.

[0004] After searching, it is found that a raw material stirring device for processing PLA biodegradable tableware is disclosed in Chinese patent documents [Application No.: 201821639455.8; Publication No.: CN 208911890U]. This raw material stirring device for processing PLA biodegradable tableware includes a stirring barrel, a base, a support leg, a side column and a cover plate. The utility model is provided with a side column, and a lifting cabin is provided inside the side column. The connecting block on the left side of the cover plate extends into the lifting cabin and is fixedly connected to the electric-controlled hydraulic push rod. The lifting of the electric-controlled hydraulic push rod can realize the up and down displacement of the cover plate. When feeding, the electric-controlled hydraulic push rod is extended, and the cover plate is separated from the stirring barrel. After the feeding is completed, the electric-controlled hydraulic push rod is controlled to shorten, so that the cover plate fits with the stirring barrel. After the motor is turned on by the corresponding control button, the raw materials placed in the stirring barrel can be stirred. After the stirring is completed, the discharge port is opened to pour out the stirred raw materials, and the water pump is turned on by the corresponding control button. The water pump sprays water from the nozzle into the stirring barrel, which can realize the rapid cleaning of the inside of the stirring barrel.
