Description

Technical Field

[0001] The utility model relates to the technical field of plasticizing plastic particles, in particular to a plasticizing device for producing plastic particles. Background Art

[0002] The biological plasticization technology is the most advanced biological specimen preservation technology in the world. Biological plasticization is a special technology that can preserve tissues like living things. It uses a vacuum process to infiltrate biological specimens with active high molecular polymers such as silicone rubber and epoxy resin. The type of polymer used determines the optical properties (transparent or opaque) and mechanical properties (soft and tough) of the infiltrated specimens. Plasticization technology can keep the surface of the specimen in its original state and preserve the structure of cells at the microscopic level. Plasticized specimens are dry, odorless, durable, can be preserved for a long time, and are easy to study. Plastic particles are roughly divided into more than 200 types, and subdivided into thousands of types. There are dozens of common types, including general-purpose plastics, engineering plastics, and special plastics.

[0003] According to patent CN 214872577 U, the utility model belongs to the field of plastic bag production equipment, especially an efficient plastic particle melting device for plastic bag production. Aiming at the problem that the melting speed of existing plastic particle melting equipment is slow, the plastic particles are not completely melted, and the working efficiency of the plastic particle melting device is reduced, the following scheme is proposed, which includes an extruder, two frame plates are fixedly installed on the top of the extruder, the top of the two frame plates are fixedly installed with the same top plate, and the top plate is fixedly installed with a feed pipe, and the two frame plates are provided with a movable groove on one side close to each other, and a movable seat is slidably installed in the two movable grooves, and the two movable seats are fixedly installed with the same melting box on one side close to each other.

[0004] The patent has a reasonable structure and is easy to operate. The melting speed of the molding particle melting device is fast, and the plastic particles are heated and melted more evenly and thoroughly, which improves the working efficiency of the plastic particle melting device. However, the plastic has adhesion after plasticization, and the plasticized plastic will adhere to the inner wall of the tank. The patent does not clean the inner wall of the tank.
