Description

Technical Field

[0001] The utility model relates to a feeding device, in particular to an auxiliary feeding device of a granulator. Background Art

[0002] The granulator is mainly used for filling, blending, modification, addition, chlorination, polypropylene and super absorbent resin processing of rubber, plastic and engineering resin. The raw materials pass through the feed port and are rolled into a ball and rolled along the screw groove under the action of the rotating screw. Due to the shearing, compression and stirring of the screw, the raw materials are further mixed and plasticized, and the temperature and pressure gradually increase, showing a viscous flow state, and forming particles after passing through the die at a certain pressure and temperature. When multiple raw materials are mixed and fed, due to insufficient mixing, it is easy to return the material, causing the raw materials to accumulate at the feed port, affecting the overall discharge.

[0005] After the turntable rotates, the guide rod slides along the guide groove, the connecting rod swings up and down under the push of the guide rod, the push rod meshing with the sector teeth slides up and down, and the push block presses the accumulated raw materials down into the feeding port.

[0006] As a further improvement of the present invention, the push rod is slidably connected to the mounting plate via a positioning block.

[0007] As a further improvement of the present invention, the cross section of the push rod is square.

[0008] As a further improvement of the present utility model, the middle portion of the transmission gear is rotatably connected to the mounting plate via a positioning shaft.

[0009] As a further improvement of the present invention, the turntable is mounted on the main shaft end of the drive motor, and the drive motor is mounted on the rear side of the mounting plate.

[0010] The beneficial effects of the utility model compared with the prior art are:

[0011] The device uses sector teeth and racks to form a gear rack mechanism. The turntable and connecting rod cooperate to drive the sector teeth to swing up and down, thereby driving the push rod and push block to reciprocate up and down, pressing the raw materials down into the feeding port to prevent the raw materials from piling up at the feeding port.
