Description

New slider-crank unloading device for laboratory internal mixers

technical field

The utility model relates to the technical field of rubber and plastic processing, in particular to a new crank slider type unloading device for a laboratory internal mixer.

Background technique

Internal mixer, also known as kneader, is mainly used for plasticizing and mixing of rubber. Internal mixer is a kind of machine with a pair of rotors with specific shape and relative rotation, which intermittently plasticizes and kneads polymer materials in a closed state with adjustable temperature and pressure. It is mainly composed of a mixing chamber, a rotor , Rotor sealing device, feeding and pressing device, unloading device, transmission device and machine base and other parts. At present, internal mixers mainly include traditional tangential (Benbury) internal mixers and intermeshing internal mixers. Partial composition. Internal mixers are needed in the experimental research and performance testing of rubber and plastic formulations. At present, there are two types of experimental internal mixers used in the rubber and plastics industry: experimental internal mixers with tangential rotors and experimental internal mixers with meshing rotors. According to the needs of the mixing process, both types of experimental internal mixers are required at the same time. At the same time, the mixing performance of the two should be compared. When the rubber is fully gelled and the rubber is hot, it is relatively soft and has a certain degree of adhesion, so that when the rubber is discharged from the discharge chamber, the rubber will adhere to the discharge chamber and cannot be discharged normally. It needs manual labor to assist discharge, and when the rubber enters the discharge chamber, it will still accumulate a certain amount of rubber material, which makes it inconvenient to discharge the discharge chamber. It is necessary to manually clean the residual rubber accumulated in the discharge chamber regularly and it is inconvenient to clean. resulting in high labor costs.
