Description

Technical Field

[0001] The utility model relates to the technical field of resin production, in particular to stirring equipment for GPPS resin production. Background Art

[0002] Resin usually refers to an organic polymer that has a softening or melting range after being heated, has a tendency to flow under the action of external force when softened, and is solid, semi-solid, or sometimes liquid at room temperature. In a broad sense, any polymer compound that can be used as a raw material for plastic products is called a resin. The relative molecular weight is uncertain but usually high. It is solid, medium solid, pseudo-solid, or sometimes liquid at room temperature. It has a softening or melting temperature range, has a tendency to flow under the action of external force, and often appears in a shell shape when broken. In a broad sense, it refers to polymers or prepolymers used as plastic substrates. It is generally insoluble in water but soluble in organic solvents. According to the source, it can be divided into natural resins and synthetic resins; according to the different characteristics of their processing behavior, it can be divided into thermoplastic resins and thermosetting resins. Resins are divided into natural resins and synthetic resins. Natural resins refer to amorphous organic substances obtained from secretions of animals and plants in nature, such as rosin, amber, shellac, etc. Synthetic resin refers to resin products obtained by chemical synthesis of simple organic matter or chemical reaction of certain natural products, such as phenolic resin, polyvinyl chloride resin, etc., among which synthetic resin is the main component of plastic.

[0003] According to the search, Chinese patent literature, announcement number: CN214020224U, discloses a stirring device for resin production. During the working process, the resin raw material is added into the stirring barrel through the resin input port, and the pigment is added into the pigment tank through the pigment input port. The output shaft of the stirring motor is driven by the stirring shaft and the stirring rods rotate to stir the resin in the stirring chamber. At the same time, the pump pumps the pigment in the pigment tank into the first pigment delivery channel opened by the stirring shaft through the delivery pipe. The pigment enters the second pigment delivery channel opened by each stirring rod and the third pigment delivery channel opened by each stirring rod through the first pigment delivery channel, and is discharged through each first delivery hole and each second delivery hole. During the stirring process, the pigment is added into the resin raw material so that the pigment and the resin raw material are fully contacted and evenly mixed. After the stirring work is completed, the stirred resin is discharged from the stirring chamber from the resin output port. The above-mentioned stirring device for resin production has high efficiency and good effect in stirring resin.

[0004] However, when the utility model is in use, the resin on the inner wall of the mixing barrel cannot be cleaned, and long-term use is likely to affect the mixing effect and the quality of the stirred resin. Utility Model Content
