Description
Technical field
The utility model belongs to technical field of tobacco processing, is specifically related to a kind of tobacco filament cutter knife roller drive unit.
Background technology
Knife roller of filament cutter is the core component of filament cutter on tobacco processing line, the cut tobacco that filament cutter drives diffusion knife to be cut into by tobacco to meet use by the rotation of cutter rod body or stem.The type of drive of rotor decides the mounting, commissioning and maintenance etc. of rotor.Existing rotor type of drive has Chinese publication 200620044849.x, the rotor type of drive of its disclosure and description is all by belt transmission or Direct driver rotor main axis by drive motors, and then rotated by the rotating band moving knife roll body of rotor main shaft, and then complete chopping work.These type of drive in actual applications motor can only be positioned over cutter rod external body, and the volume that takes up room is large, there is the deficiencies such as noise is large, maintaining amount is large in using.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of structure simple, the volume that takes up room is little, knife roller driving device easy to use.
The purpose of this utility model is achieved by the following technical solution.
A kind of knife roller of filament cutter drive unit, the utility model is characterised in that, comprising: the roller cutter body that cutter rod main shaft, cover are connected on cutter rod main shaft and external rotor electric machine; Wherein, external rotor electric machine is arranged on the rotation of cutter rod body inner also Direct driver cutter rod body; Knife roller of filament cutter main shaft maintains static; The outer ring of external rotor electric machine and rotor are fixedly connected with cutter rod body, and by bearings on rotor main shaft, the rotor of external rotor electric machine drives roller cutter body around rotor main axis, thus drives diffusion knife to complete chopping work; The inner ring of external rotor electric machine and stator are fixedly connected with rotor main shaft, and rotor main shaft two ends are fixed on support.
Stator and the rotor main shaft of the utility model external rotor electric machine are integrated, and namely the stator of outer rotor had both been main shaft that the stator of external rotor electric machine is also cutter rod body.
Utility model works mode is, stator and the rotor main shaft of external rotor electric machine are connected, and are fixed on support; Rotor and the cutter rod body of external rotor electric machine are connected, and by bearings on rotor main shaft, the rotor of external rotor electric machine drives roller cutter body around rotor main axis, thus drives diffusion knife to complete chopping work.
Advantage of the present utility model is simple in rotor type of drive structure, takes up room less, uses middle noise little, safeguards few, is user-friendly to.
Content of the present utility model is set forth further below in conjunction with Figure of description and embodiment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In Fig. 1,1 is that rotor main shaft, 2 is for cutter rod body; 3 for external rotor electric machine, 3a be rotor, 3b be stator, 4 is support.
Detailed description of the invention
As shown in Figure 1, a kind of knife roller of filament cutter drive unit, the utility model is characterised in that, comprising: the roller cutter body 2 that cutter rod main shaft 1, cover are connected on cutter rod main shaft 1 and external rotor electric machine 3; Wherein, external rotor electric machine 3 is arranged on the inner and Direct driver cutter rod body 2 of cutter rod body 2 and rotates; Knife roller of filament cutter main shaft 1 maintains static; The outer ring of external rotor electric machine 3 and rotor 3a are fixedly connected with cutter rod body 2, and by bearings on rotor main shaft 1, the rotor 3a of external rotor electric machine drives roller cutter body 2 to rotate around rotor main shaft 1, thus drives diffusion knife to complete chopping work; Inner ring and the stator 3b of external rotor electric machine 3 are fixedly connected with rotor main shaft 1, and rotor main shaft 1 two ends are fixed on support 4.
Stator 3b and the rotor main shaft 1 of the utility model external rotor electric machine 3 are integrated, and namely the stator 3b of outer rotor had both been main shaft that the stator of external rotor electric machine is also cutter rod body.
Utility model works mode is, stator 3b and the rotor main shaft 1 of external rotor electric machine are connected, and are fixed on support 4; Rotor 3a and the cutter rod body 2 of external rotor electric machine are connected, and by bearings on rotor main shaft 1, the rotor 3a of external rotor electric machine drives roller cutter body 2 to rotate around rotor main shaft 1, thus drives diffusion knife to complete chopping work.
Using method of the present utility model is: when filament cutter needs work time, control system controls external rotor electric machine 3 and rotates, rotated around rotor main shaft 1 by the rotating drive roller cutter body 2 of the rotor 3a of external rotor electric machine, the rotation of cutter rod body 2 drives the diffusion knife being arranged on its inside to complete chopping work.
Claims (2)
