Granulation die head device for increasing extrusion pressure

Abstract

The invention discloses a granulation die head device for increasing extrusion pressure. The granulation die head device comprises a transversely-arranged first pipe body, a second pipe body is arranged at the top of the first pipe body in a communicating mode, one end of the first pipe body is sealed, a plurality of discharging holes are formed in the sealed end, an end cover is arranged at the other end of the first pipe body, and a through hole is formed in the middle of the end cover; a piston block is slidably arranged in the first pipe body, a pressing rod is arranged in the middle of the end, away from the discharging hole, of the piston block, and the piston block is matched with the inner wall of the first pipe body; the end, away from the piston block, of the pressing rod is connected with a pressing plate, a hydraulic cylinder is fixedly installed at the bottom of the first pipe body, and the end of a piston rod of the hydraulic cylinder is fixedly connected with the pressing plate; and a ball valve is installed on the second pipe body, a pushing piece is installed on the pressing plate, and the transversely-moving pressing plate drives the ball valve to be opened or closed through the pushing piece. The granulation die head device is novel in structure, materials retained in the die head can be effectively reduced before batch production and machining are stopped, excessive material solidification is prevented, the preheating time of subsequent machining is shortened, consumption is reduced, and efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of granulation dies, in particular to a granulation die device for increasing extrusion pressure. Background technique [0002] A granulator is a molding machine that can make materials into granules. Most polymers must be kneaded before being made into final products, and then granulated to become salable raw materials; mainly by melting materials, when The polymer in the molten state is cut into pellets when it emerges from the die, and the pellets are cooled downstream; most of the existing extrusion dies are simple die structures. If there are a lot of materials left behind, if they are not used for a period of time, the molten materials will re-solidify, resulting in the need for a longer period of preheating during subsequent processing, affecting production efficiency and consuming more energy. Contents of the invention [0003] In order to overcome the defects of the prior art, the technical probl...
