Abstract

A kneading device kneads a main raw material of high viscosity and a secondary raw material of liquid or powder and continuously delivers a kneaded raw material obtained, and a ropesizer includes a sheet forming unit, and a delivering unit applies a second raw material onto a first raw material, which is elongated into a sheet shape and is conveyed by the sheet forming unit, so as to be in a strand form.

Claims

1. A kneading device comprising:

a casing having an opened upper portion;

a pair of mixing blades disposed parallel to each other in said casing; and

a drive unit to rotate said mixing blades, wherein

each of said pair of mixing blades comprises a unit blade of a U-shape continuously attached in a wavy shape, and said pair of the mixing blades rotate with their rotational phases shifted so that they do not interfere with each other, and

each said mixing blade includes an inclined portion oriented towards an outlet end of said mixing blades, said inclined portion including a surface to face a rotation direction and being structured so that, in use, raw materials are continuously conveyed towards the outlet end.

2. A kneading device according to claim 1, wherein each of said pair of mixing blades is configured so as to rotate inwardly from top to bottom.

3. A kneading device according to claim 1, wherein a longitudinal bar and a lateral bar are provided with said mixing blades so as to be alternately connected.

4. A kneading device according to claim 1, wherein said inclined portion has an inclination angle of inclination about 5-15°

.

5. A kneading device, comprising:

a casing having an opened upper portion;

a pair of mixing blades disposed parallel to each other in said casing; and

a drive unit to rotate said mixing blades, wherein

each of said pair of mixing blades comprises a unit blade of a U-shape continuously attached in a wavy shape, and said pair of the mixing blades rotate with their rotational phases shifted so that they do not interfere with each other, and

an inclined portion oriented towards an outlet end of said mixing blades is provided with a surface of said mixing blades facing a rotation direction thereof so that raw materials are conveyed towards the outlet end,

said kneading device further comprising;

an inclination member for changing the angle of inclination of said inclined portion which is detachably attached to said inclined portion.
