Detailed Description

Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

In the description of the present utility model, the meaning of "a plurality" is two or more, unless explicitly defined otherwise.

The tobacco shred cutting device comprises a frame 300 and a shell 400, wherein the frame 300 comprises four upright posts 301, a structure of a solid shell 400 is formed by fixedly connecting cross beams 302 among the upright posts 301, a processing cavity 401 is formed by enclosing the shell 400, a feed inlet 402 and a discharge outlet 403 are formed in the surrounding mode, the processing cavity 401 is used for cutting cut tobacco shreds, namely, the installation positions of two groups of cutters are arranged, a material entering the feed inlet 402 falls into a working area between the cutters, each group of cutters is respectively formed by uniformly fixing cutter shafts at intervals of a plurality of blades, the blades and the cutter shafts are in a sleeved structure, axial limiting can be achieved through spline or key connection, axial interval control and positioning can be achieved through sleeve arrangement, and thickness of a sleeved part of each cutter blade can also be achieved through arrangement. The two ends of the cutter shaft respectively penetrate through the shell 400 to form rotary connection with the frame 300 through the bearing seat and the bearing, the other end of the cutter shaft is connected with a rotary wheel or is connected with a direct-connection motor through a coupler for driving, and as a preferable scheme, the cutter shaft is in transmission connection with the driving motor through a belt pulley.
