Plastic stirrer used for cable sheath production

Abstract

The invention discloses a plastic stirrer used for cable sheath production. The plastic stirrer comprises a charging screw cylinder, a pressure screw cylinder, a shaftless twisting and feeding screw,a locator and a power cavity, wherein the charging screw cylinder is spirally connected with the pressure screw cylinder; the shaftless twisting and feeding screw is arranged inside the charging screwcylinder and the pressure screw cylinder; one end of the locator is adaptive to the shaftless twisting and feeding screw, and the other end of the locator is adaptive to the power cavity; spacing ofblades of the shaftless twisting and feeding screw is gradually reduced from the charging screw cylinder to the pressure screw cylinder; the locator is equipped with a pressure probe; the pressure probe is connected to a computer; and the inner wall of the pressure screw cylinder is equipped with threads which are reverse to the shaftless twisting and feeding screw. According to the plastic stirrer used for cable sheath production disclosed by the invention, materials are extruded inside the shaftless twisting and feeding screw, so that friction resistance between the materials and a screw cylinder wall is reduced, and therefore, compactness of plastic products is improved.

Description

technical field [0001] The invention relates to the field of cable sheath manufacturing, in particular to a plastic mixer. Background technique [0002] Extruders are widely used in plastic production. Most of the extruders currently on the market are single-screw extruders. The abnormal wear of the single-screw and the screw cylinder will occur when the single-screw rings and foreign objects are stuck. Ring knot means that the single screw is locked by the condensed material. If the single screw extruder lacks a good protection device, the strong driving force may twist the screw, making the produced plastic products low in density. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to provide a plastic mixer for the production of cable sheaths in view of the deficiencies in the prior art. [0004] Technical solution: A plastic mixer for cable sheath production according to the present invention, including a feeding screw...
