A mixing device with rotatable container, which comprises
- a fixed container (4), having a top opening and defining a receiving cavity;
- a mixing container (3) having a top opening and defining a mixing cavity, received inside said fixed container (4), rotatably connected to said fixed container (4) and having a material outlet (260) at a bottom of said mixing container (3),
- a discharge and sealing mechanism, which comprises a piston (5) arranged inside said mixing container (3) for opening and closing said material outlet (260);
- characterized in that, said mixing device with rotatable container further comprising:
- a driving cover (1) configured to be driven to open or close said top opening of said fixed container (4), and arranged coaxially with said piston (5) to form an integral body;
- a linear motion mechanism (6) which comprises a fixed part (601) and a moveable part (602), control said driving cover (1) being driven to open or close said fixed container (4), wherein said fixed container (4) is installed on said fixed part (601) of said linear motion mechanism (6) and said driving cover (1) is installed on said moveable part (602) of said linear motion mechanism (6);
- a mixing container cover (2) coaxially arranged with said driving cover (1) and arranged to rotate relative to said driving cover (1), forming an integral body with said driving cover (1), wherein said mixing container cover (2) is configured to be driven to open or close said top opening of said mixing container (3) and to rotate synchronously with said mixing container (3) after said mixing container (3) is covered by said mixing container cover (2);
- a hollow driving shaft (18) installed inside said hollow shaft reduction motor (9);
- a main commutator gear housing (15) mounted below said driving cover (1) and in sealed contact with said mixing container cover (2);
- wherein said hollow driving shaft (18) is arranged on said driving cover (1) and said main commutator gear housing (15) and is capable of having rotational movement relative to said driving cover (1) and said main commutator gear housing (15);
- an auxiliary commutator gear housing (16) connected to said main commutator gear housing (15) through a horizontal drive arm (23);
- a mixer center shaft (17) installed on said auxiliary commutator gear housing (16);
- a mixing rotor (14) mounted on said mixer center shaft (17),
- a scraper (13) mounted on said main commutator gear housing (15), wherein said scraper (13) is clearance fit with both a side wall and a bottom of said mixing container (3) at the same time, a vertical outer edge of said scraper (13) forms a non-contact clearance fit with a side wall of said mixing container (3), an outer edge of said bottom side of said scraper (13) is clearance fit with an upper plane of said bottom of said mixing container (3), and said scraper (13) is spaced apart from said mixing rotor (14);
- said discharge and sealing mechanism further comprising a driving rod (27) and a fifth sealing member (34);
- wherein said driving rod (27) is sleeved inside said hollow driving shaft (18) and is controlled by a linear driving mechanism (8) installed on said driving cover (1) to realize linear movement, said fifth sealing member (34) is arranged between said driving rod (27) and said hollow driving shaft (18), said hollow driving shaft (18) is provided on said driving cover (1) and said mixing container cover (2), said piston (5) is mounted at a lower end of said driving rod (27), said piston (5) is capable of having rotational movement relative to said driving rod (27), and said piston (5) is configured to be driven to linear movement relative to said driving cover (1) to realize the closing or opening of said material outlet (260) from the inside, after said piston (5) closes said material outlet (260), said piston (5) is configured to rotate synchronously with said mixing container (3) when said mixing container (3) is driven to having rotational movement.
