Feeding adjuster of screw extruder

Abstract

The invention relates to a feeding adjuster of a screw extruder. The feeding adjuster comprises a sleeve, the upper end of the sleeve is connected with a feeding screw, the lower end of the sleeve isused for being connected with a main feeding screw, an adjustment sheet arranged in the sleeve through a through connection structure is included, and the adjustment sheet can rotate in the sleeve; and the through connection structure comprises installing holes transversely penetrating the sleeve and an adjusting rod in through connection with the installing holes, an adjusting block used for connecting the adjusting sheet and the adjusting rod is further included, the front face of the adjusting block is connected with the back face of the adjusting sheet, the back face of the adjusting blockis connected with the adjusting rod through a height adjusting structure, and the adjusting rod is connected with the installing holes through positioning structures. By means of the feeding adjuster, flying, scattering and splashing in the material falling process can be avoided, pollution of materials, in particular to powder, to equipment and the environment can be prevented, and the stabilityof the production process and the stability of the product quality can be improved.

Description

technical field [0001] The invention relates to a screw extruder, in particular to a feed regulator of the screw extruder. Background technique [0002] Screw extruder is one of the most important and main equipments for polymer processing. At present, more than 70% of resins are processed by screw extrusion, including rods, films, plates, tubes, profiles and fibers. Direct molding of products such as hollow blow molding and extrusion of thermoforming blanks. Moreover, in the process of production and processing, screw extrusion has largely replaced conventional processes such as refining and banburying. In addition, the advanced technology of screw extrusion is almost all used in the pretreatment processes such as resin transportation, pressurization, deashing, drying, coloring, and impurity removal. With the development of science and technology, screw extrusion has taken on more functional processes, such as grafting, crosslinking, foaming, block, polymerization and adj...

AI Technical Summary

Problems solved by technology

However, especially when processing powder, due to the large direct drop (usually about 20-30cm), the material is easy to float under this condition, resulting in serious material loss, increasing production costs, and causing pollution to equipment and the environment.

[0004] At present, the connection between the feed port of the screw extruder and the main screw is generally connected by a tube. The material is easy to scatter, which is easy to cause unnecessary loss and waste, and the floating material is easy to pollute the equipment and the environment. In addition, because the material is floating If the state falls into the main screw, it is easy to cause adverse effects on the stability of screw extrusion, which will lead to unstable product quality
