Detailed Description

The technical solution of the present invention is further explained by the specific embodiment with reference to fig. 1 to fig. 2.

The flexible blade assembly of the pelletizer shown in fig. 1 and 2, comprising: the tool apron comprises a driving shaft 2, a tool apron 1, a tool shank 3, a spring, a blade 4 and a pressing plate 6, wherein the tool apron 1 is concentrically arranged at the front end of the driving shaft 2, the tool apron 1 is connected with the driving shaft 2 in a threaded mode or a welding mode, and the structure is stable. The rotation of the driving shaft 2 can be driven by a speed reduction motor of the granulator to drive the cutter holder 1 to rotate.

In this embodiment, the tool holder 1 has a cylindrical structure, and the rotational stability is good. The front end of the tool apron 1 is provided with the stepped hole 11 in an inwards concave mode, so that weight reduction can be achieved, the bearing can be installed, and stability of the tool apron 1 during rotation is improved through matching of the bearing and a positioning shaft of the end face of the die head.

The tool holder 3 is arranged outside the tool holder 1, in this embodiment, the tool holders 3 are distributed outside the tool holder 1 in an annular array manner and radially extend along the tool holder 1, and the weight distribution is uniform. The blade 4 is arranged at the front end of the knife handle 3, as shown in fig. 1, the blade 4 is arranged on the back face of the front end of the knife handle 3, and the pressing plate 6 is arranged on the side face of the blade 4 and is matched with the knife handle 3 to clamp the blade 4. The pressing plate 6 is provided with a second screw 5 which penetrates through the blade 4 and is connected with the knife handle 3, and the second screw 5 improves the stability and the dismounting convenience of the blade 4.
