Problems solved by technology

[0013] However, when the tire raw material added with silica is kneaded in the kneading chamber, the inner surface of the kneading chamber is easily abraded.
In this case, there is a problem that sufficient wear resistance cannot be obtained by conventional chrome plating and overlay welding
Here, although the thermal spray coating described in Patent Documents 1 and 2 can be applied to the inner surface of the kneading chamber to improve wear resistance, it is difficult to directly apply it because the shape of the inner surface of the kneading chamber and the surface of the rotor are completely different.

[0083] Next, a kneader 40 according to a second embodiment of the present invention will be described.

[0084] In addition, the same code|symbol is attached|subjected to the component common to 1st Embodiment, and detailed description is abbreviate|omitted.

[0085] In this embodiment, the shape of the edge part 42a of the protection member 41 and the hard film 42 differs from 1st Embodiment.

[0086] Such as Figure 4 As shown, the hard film 42 has a first inclined surface 42b that is inclined from the kneading chamber C side to the inner surface 2c at the edge portion 42a and is directed toward the inner surface 2c side. Here, the first inclined surface 42b is formed by machining or the like, for example.

[0087] The protection member 41 has a triangular cross section on a plane perpendicular to the axis P2 ( P1 ). Specifically, it has a second inclined surface 41b that is inclined from the kneading chamber C side to the inner surface 2c and faces the kneading chamber C...

[0090]Next, a kneader 50 according to a third embodiment of the present invention will be described.

[0091] In addition, the same code|symbol is attached|subjected to the component common to 1st Embodiment and 2nd Embodiment, and detailed description is abbreviate|omitted.

[0092] In this embodiment, the shape of the protective member 51, the edge part 52a of the hard film 52, and the installation method of the protective member 51 differ from 1st Embodiment and 2nd Embodiment.

[0093] Such as Figure 5 As shown, the hard film 52 has a first curved surface 52b, and the first curved surface 52b is inclined from the kneading chamber C side to the inner surface 2c at the edge portion 52a, and is concavely curved toward the kneading chamber C side toward the inner surface 2c side. . Here, the first inclined surface 52b is formed by machining or the like, for example.

[0094] The protection member 51 has a second curved surface 51b that is inclined from the kneading chamber...

Abstract

A kneading machine (1), which stores a kneaded material (W) in a kneading chamber (C), and kneads with kneading rotors (4), (5), having: a chamber (2), The mixing chamber (C) is separated from the outside; the hard film (20) covers the inner surface (2c) of the chamber (2) facing the mixing chamber (C), and is resistant to the mixing material (W) The protective member (21), on the inner surface (2c) of the chamber (2), covers the edge portion (20a) of the hard film (20), and is made of a material that is more durable than the material forming the hard film (20). High toughness material formation.

Description

technical field [0001] The present invention relates to a kneader for stirring kneaded materials such as rubber raw materials and components for the kneader. [0002] This application claims priority based on Japanese Patent Application No. 2013-033841 for which it applied to Japan on February 22, 2013, and uses the content here. Background technique [0003] There is known a closed type kneader which agitates a kneaded product of raw materials such as tires and the like made of rubber, plastic, etc., which are pressed into a kneading chamber by rotation of a rotor shaft. When this type of kneader is kneading the kneaded material, the kneaded material will cause wear to the rotor and the inner surface of the mixing chamber. [0004] Then, Patent Document 1 describes a rotor in a kneader in which a thermal sprayed coating of cermet is laminated on the surface of the rotor, and efforts are made to achieve wear resistance and corrosion resistance. In addition, Patent Document...
