Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given. A plastic particle feeding machine is shown in figures 1 and 2 and comprises a machine frame 1, wherein a mixing tank 2 is fixed at the top of the machine frame 1, a feeding hole 3 is formed in the top end of the mixing tank 2, a discharging hole 4 is formed in the bottom of the mixing tank 2, and a feeding device is arranged below the discharging hole 4; the method is characterized in that: a plurality of layers of horizontal partition plates 5 are arranged in the mixing tank 2, and a plurality of through holes 6 are formed in each layer of partition plate 5; the middle part of the top end of the mixing tank 2 is rotatably connected with a vertical rotating shaft 8, and the rotating shaft 8 is connected with a driving device; the rotating shaft 8 is rotatably connected with each layer of partition board 5, and the positions of the rotating shaft 8, which are opposite to the upper surface of each layer of partition board 5, are respectively fixed with a stirring blade 9; the side wall of the mixing tank 2 is connected with an air blowing pipe 10 and an air exhaust pipe 11 which blow hot air at positions above each layer of partition plate 5.

The stirring blades 9 are obliquely arranged; the inclined direction of the stirring blade 9 is the same as the rotating direction of the rotating shaft 8; the mixing tank 2 is provided with filter screens 12 at positions corresponding to the air blowing pipe 10 and the air exhaust pipe 11; the feeding device comprises a fixed frame 19, and the fixed frame 19 is connected with a material collecting hopper 13 positioned below the discharge hole 4; a feeding screw structure 14 which inclines upwards is fixed at an opening at the bottom end of the aggregate bin 13, and the top of the feeding screw structure 14 is connected to a feeding bin of a heating screw; the driving device comprises a driving motor 15 fixed on the side wall of the mixing tank 2, the top end of the driving motor 15 is connected with a driving wheel 16, one side of the driving wheel 16 is provided with a driven wheel 17 connected to the top of the rotating shaft 8, and a transmission belt 18 is connected between the driven wheel 17 and the driving wheel 16.
