Double hydraulic internal mixer

Abstract

The invention discloses a double hydraulic internal mixer. A rack is arranged on a rack base; a first hydraulic cylinder and a second hydraulic cylinder are arranged on the rack; position rods of the first hydraulic cylinder and the second hydraulic cylinder are connected with a top peg; a piston rod guiding device is arranged in the middle of the rack; the upper part of a piston rod is connected with the top peg; the lower part of the piston rod is connected with the piston rod guiding device; supporting seats are arranged on the rack base; a rotor is arranged on the supporting seats and is connected with a mixing mechanism; and the mixing mechanism is connected with a driving mechanism through a speed ratio mechanism. According to the double hydraulic internal mixer disclosed by the invention, the stability is good; the pressure acting on materials is uniform; due to the adoption of double hydraulic design, the problem of oil leakage in the prior art is solved; by adoption of a triangular design, the top peg has the stability; a rack guiding sleeve adopts a double sealing intermediate oil channel design, so that unnecessary wear of the piston rods when the piston rods vertically move due to dust leakage, and dust left on the piston rods and the like is avoided, and the service life of the piston rods is prolonged; and a top peg hydraulic mechanism separately adopts bolts for connecting and mounting.

Description

technical field [0001] The invention relates to the technical field of rubber and plastic machinery, in particular to an internal mixer. Background technique [0002] Double hydraulic internal mixer is widely used in rubber and plastic products industry, such as: tire factory, cable factory, tape hose factory, rubber shoe factory, seal factory, calcium plastic product factory, etc. It is also suitable for paint, dye, medicine, tape, film, etc. Compounding production in film and other factories. The traditional kneader has the following disadvantages: (1) The traditional internal mixer adopts the air pressure type, and the pressure on the material is unstable due to the unstable air source, water in the air source, etc., and the mixing effect is not good; ( 2) Pneumatic kneader is lubricated by triple lubricating air circuit, the piston rod will have oil leakage, and oil leakage into the mixing chamber will cause material pollution, product quality degradation or scrap.
