Detailed Description

The technical solution of the present invention is further explained with reference to the drawings and the embodiments.

As shown in fig. 1, in order to improve the mixing efficiency of the mixer, the embodiment of the utility model provides a mixer for plastic production, which comprises a tank body 1, a stirring shaft 5 coaxially and rotatably arranged in the tank body 1, and a feeding pipe 2 and a discharging pipe 3 respectively fixed at the top and the bottom of the tank body 1, wherein a tray 4 for separating the interior of the tank body 1 is horizontally fixed at the middle part of the tank body 1, the tray 4 is in a downward convex hemispherical shape and is coaxially arranged with the stirring shaft 5, an opening is formed in the middle part of the tray 4, a baffle plate 7 is uniformly fixed on the stirring shaft 5 around an axis, the baffle plate 7 is positioned in the tray 4 and is attached to the inner wall of the tray 4, and a stirring rod 11 is uniformly fixed at the bottom of the stirring shaft 5 along the axis.

The top of the tank body 1 is provided with two feeding pipes 2, the middle of the top of the tank body 1 is provided with a driving piece 6, the driving piece 6 comprises a motor and a speed reducer which are in transmission connection, and an output shaft of the speed reducer is coaxially and fixedly connected with the top end of the stirring shaft 5; raw materials are input through one inlet pipe 2, auxiliary materials are input through the other inlet pipe 2, the auxiliary materials and the raw materials fall on the tray 4, the motor drives the stirring shaft 5 to rotate through the speed reducer, the stirring shaft 5 drives the partition plate 7 to rotate, the partition plate 7 pushes the raw materials and the auxiliary materials to rotate in the rotating process, meanwhile, the raw materials and the auxiliary materials slide downwards along the inner wall of the tray 4 in the tray 4 and fall down from the opening in the middle of the tray 4, when the material is fed, the raw material and the auxiliary material continuously enter the gap between two adjacent partition boards 7, so that the raw material and the auxiliary material are uniformly added in the gap, so that the raw materials and the auxiliary materials flowing out from the opening at the middle part of the tray 4 are primarily mixed and then are further mixed by the stirring rod 11, make raw materials and auxiliary material misce bene in the jar body 1, shortened puddler 11's churning time, and then improved the mixing efficiency of raw materials and auxiliary material.

As shown in fig. 1-2, in order to improve the stirring stability of the stirring shaft 5, a reinforcing pipe 8 is fixedly connected to the opening of the tray 4 in a vertical manner, the reinforcing pipe 8 is coaxial with the stirring shaft 5, a lantern ring is fixedly connected to the inside of the reinforcing pipe 8 through a connecting rod 9, and the lantern ring is connected to the stirring shaft 5 through a bearing.
