Seating-type internal mixer

Abstract

The invention relates to a seating-type internal mixer which comprises a base, a mixing chamber, a transmission mechanism, rotors, a discharging mechanism, a feeding chamber, a material pressing mechanism and a feeding mechanism, wherein the mixing chamber is mounted above the base; the two rotors are mounted in the mixing chamber; the transmission mechanism is mounted on one side of the mixing chamber; the feeding chamber is mounted above the mixing chamber; the feeding chamber is communicated with the mixing chamber; a feeding door is arranged on one side of the feeding chamber; the feeding mechanism drives the feeding door to move upwards to open the hermetically sealed feeding chamber. According to the seating-type internal mixer, the structural design is reasonable and compact, the advantages of a falling type internal mixer and a turnover type internal mixer are integrated, the structural defects of the conventional internal mixer are overcome, the production speed is high, the requirement on the height of a factory space during installation is low, the space is economized, the mixing capacity is high, the mixing time is short, the production efficiency is high, the degree of automation is high, the product quality and the working environment are improved, the operation is safe and convenient, the labor intensity is reduced, and the labor cost is reduced.

Description

technical field [0001] The invention relates to a ground type internal mixer. Background technique [0002] The internal mixer, also known as the kneader, is mainly used for the mastication and mixing of rubber. It is a kind of rotor with a pair of specific shapes and relatively rotating. It is a mechanical equipment for plasticizing and mixing materials. The existing internal mixers are mainly divided into two types: drop type and flip type. Driven by rack and gear and hydraulic cylinder, the operation is stable and reliable, and the opening and closing time is short. It adopts bellcrank type locking and is driven by hydraulic cylinder. It has strong locking force, good self-locking performance and good sealing, but it needs two to three layers. The installation space of a one-story building has high installation costs and requires a lot of space; the mixing chamber of the flip-type floor mixer adopts a front and rear combined structure, and the entire mixing chamber can b...

[0002] The internal mixer, also known as the kneader, is mainly used for the mastication and mixing of rubber. It is a kind of rotor with a pair of specific shapes and relatively rotating. It is a mechanical equipment for plasticizing and mixing materials. The existing internal mixers are mainly divided into two types: drop type and flip type. Driven by rack and gear and hydraulic cylinder, the operation is stable and reliable, and the opening and closing time is short. It adopts bellcrank type locking and is driven by hydraulic cylinder. It has strong locking force, good self-locking performance and good sealing, but it needs two to three layers. The installation space of a one-story building has high installation costs and requires a lot of space; the mixing chamber of the flip-type floor mixer adopts a front and rear combined structure, and the entire mixing chamber can be turned 110-140° around the front rotor for unloading and cleaning, but there are shortcomings such as insufficient rigidity, slow feeding, easy leakage of material and powder, pollution of the environment, poor quality of mixed rubber, and unfavorable for automatic production. The system devices have poor coordination, and all have disadvantages such as difficult feeding, low production efficiency, insufficient rotor rolling, insufficient heat dissipation, and material leakage in the mixing chamber.
