Description
Technical field:
The utility model relates to the hob type tobacco cutting machine in the tobacco cutting equipment, the particularly filament cutting mechanism of hob type tobacco cutting machine.
Background technology:
Tobacco cutting is the important step in the cigarette producing process, and the quality of pipe tobacco directly has influence on the quality of cigarette.The hob type filament cutter is the visual plant of tobacco cutting, and the task of its filament cutting mechanism is exactly on request evenly, efficiently cake is cut into silk.This just requires cake to be in comparatively stable status in compacting and course of conveying, guarantees that compacted density is constant.The disclosed filament cutting mechanism of Chinese patent ZL99241281.1 " filament cutting mechanism of tobacco cutting equipment " is to install auxilliary swinging mechanism and auxiliary guide plate on existing filament cutter mono-pendulum type assembly additional, realize balanced wobble component, make the rotary track of upper slitter door cutting edge line and blade cutting edge keep constant, improved the chopping quality in the gap at cutter door position.What the RC4 type filament cutter of Britain Lego Corp adopted is built-in parallel moving mechanism, promptly the row's of going up chain component places the frame inboard, because last row's chain component is to be suspended in the frame, so mechanism's integral rigidity is relatively poor, it is finished compacting and is carrying in the process of cake, the row's of causing chain carriage preshoot easily, and drive the upper slitter door be fixed thereon and eject and cause chopper.Secondly because mechanism is built-in, big gap is arranged in row's chain and two frames on it, cause tobacco leaf, offal when carrying, to fall in row's chain easily, cause chopper, influence chopping quality and filament cutter production stability and eject the upper slitter door from gap location.In addition, its structure is comparatively complicated, the maintenance difficulty.
Summary of the invention:
The purpose of this utility model is the technical scheme that proposes a kind of filament cutting mechanism of new hob type tobacco cutting machine, this scheme be by external crank and slide block synchronously, translation in the same way, last row's chain carriage produces translation, make upper slitter door cutting edge line keep constant in the gap at cutter door position at the movement locus and the blade cutting edge rotary track at cutter door position, when production capacity increases substantially, it is stable that the chopping quality still can keep, and solve the relatively poor and row's chain leakage scarp of original filament cutting mechanism integral rigidity, cause the upper slitter door to eject the chopper problem.
Structure of the present utility model is: the filament cutting mechanism of hob type tobacco cutting machine, include a left side, right frame (1), (12), last row's chain carriage (7), rotating shaft (3), a left side, right rail plate (4), (18), rear axle (11), a left side, right dead axle (9), (13), the axis of guide (5), a left side, right guide plate (6), (21), upper slitter door (2), last row's chain (19) and tensioning apparatus (8), it is characterized in that: moving component places a left side, the right frame outside, on arrange the chain carriage, rotating shaft, rear axle, a left side, right dead axle, a left side, a right rail plate and a left side, right connecting plate constitutes the crank block parallel-crank mechanism.
Moving component places the frame outside, the left and right sides to be meant, rotating shaft (3) two ends are passed by the frame wallboard, left and right coulisse of the rotating connection of two axial ends (4) (18) and left and right guide plate (6), (21), fixedly connected with frame in left and right dead axle (9), (13), the left and right connecting plate of the rotating connection of two axial ends (10), (14) and sprocket wheel (16), (17), rear axle (11) two ends are passed by the frame wallboard, the rotating connection of two axial ends left and right sides connecting plate (10) (14) and sprocket wheel (15).
The crank block parallel-crank mechanism is meant left and right dead axle center A
2Be positioned at row's chain carriage (7) top, rotating left and right connecting plate (10), (14) of being connected with on dead axle and the rear axle; Last row's chain carriage (7) is a connecting rod, and rotating shaft (3) and rear axle (11) are slide block, and left and right connecting plate is a crank; Dead axle and frame be not for being rotatably connected, and rear axle and frame are for being rotatably connected; R
