Tobacco foreign matter intelligence device for eliminating automatic deviation rectifying device
Technical field
The utility model relates to a kind of tobacco machine, the foreign matter intelligence device for eliminating that grows tobacco especially, specifically the foreign matter intelligence device for eliminating automatic deviation rectifying device that grows tobacco.
Background technology
As everyone knows, tobacco can be mixed in processes such as growth, harvesting, packing, transportation all kinds of impurity, in order to guarantee the quality of cigarette, cut into slices or chopping before it must be rejected, therefore, in the tobacco leaf process, must use the foreign body eliminating device, and tobacco foreign matter intelligence device for eliminating commonly used at present is made up of parts such as high-speed belt, detection part, rejecting valves, tobacco material is paved on high-speed belt by checkout gear, if discovery has foreign matter then rejects valve accordingly and move its rejecting.And because the very thin thickness of high-speed belt, the speed of service very fast (being generally the 5-7 meter per second), because foozle and unbalance stress, in running sideslip will inevitably take place, if do not rectified a deviation, then belt departs from the roll shaft center at short notice probably and damages, but owing to be subjected to the influence of device for eliminating structure, existing all kinds of deviation correcting device must design a kind of deviation correcting device that can satisfy this type of high-speed belt use as early as possible because reaction is slow, and volume can't satisfy its instructions for use greatly.
Summary of the invention
The purpose of this utility model is at tobacco foreign matter intelligence device for eliminating high speed belt sideslip and influence the problem of its normal operation very easily, the design one foreign matter intelligence device for eliminating automatic deviation rectifying device that grows tobacco.
The technical solution of the utility model is:
The one foreign matter intelligence device for eliminating automatic deviation rectifying device that grows tobacco comprises that the accent mandrel holds 3, it is characterized in that transferring mandrel to hold 3 and is installed on the leather belt roller 2, and high-speed belt 1 is installed on the leather belt roller 2, in a side or two sides of high-speed belt 1 sensor 12 is installed; Transferring mandrel to hold 3 links to each other with an end of regulating screw mandrel 5, after passing frame 4, the other end of adjusting screw mandrel 5 is installed among the feed screw nut 6, feed screw nut 6 is installed in the driven bevel pinion 7, and driven bevel pinion 7 and feed screw nut 6 are installed on the thrust bearing 8 together, and thrust bearing 8 is installed in the spirit 9 of living; Driven bevel pinion 7 is meshed with driving bevel gear 10, and driving bevel gear 10 is installed on the output shaft of stepper motor 11.
The beneficial effects of the utility model:
The utlity model has simple in structure, easy to adjust, the advantage that be quick on the draw, volume is little.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
The one foreign matter intelligence device for eliminating automatic deviation rectifying device that grows tobacco comprises and transfers mandrel to hold 3 that the accent mandrel holds 3 and is installed on the leather belt roller 2, and high-speed belt 1 is installed on the leather belt roller 2, in a side or two sides of high-speed belt 1 sensor 12 is installed; Transferring mandrel to hold 3 links to each other with an end of regulating screw mandrel 5, after passing frame 4, the other end of adjusting screw mandrel 5 is installed among the feed screw nut 6, feed screw nut 6 is installed in the driven bevel pinion 7, driven bevel pinion 7 and feed screw nut 6 are installed on the thrust bearing 8 together, thrust bearing 8 is installed in the spirit 9 of living, feed screw nut 6 and driven bevel pinion are worked under the support of the spirit 9 of living that is equivalent to universal joint, and (annotate: the spirit 9 of living is a kind of common frame for movement, it is a kind of rotatable and axially movable mechanism, is equivalent to the back shaft of an activity herein); Driven bevel pinion 7 is meshed with driving bevel gear 10, and driving bevel gear 10 is installed on the output shaft of stepper motor 11.
Operation principle of the present utility model is:
When high-speed belt 1 runs up under the drive of active leather belt roller, if generation deviation phenomenon, the sensor 12 that then is installed in high-speed belt one side is sensed this variation immediately, and variable signal sent in the control device, the signal that control device is sent here according to the sensor of a side (or two sides) is made the judgement of belt deviation direction, and send instruction for immediately stepper motor 11, stepper motor 11 drives driving bevel gear 10 and rotates, driving bevel gear 11 drives driven bevel pinion 7 and rotates, driven bevel pinion 7 drives coupled feed screw nut 6 and rotates, feed screw nut 6 drives screw mandrel 5 and moves along the belt rotation direction, transfer mandrel to hold 3 distances thereby drive with respect to frame 4, transfer mandrel to hold 3 drive leather belt rollers 2 and carry out front or rear moving, thereby realize the purpose of correction.
During concrete enforcement, deviation correcting device of the present utility model can also can respectively be installed a cover deviation correcting device in two sides of high-speed belt in the monolateral installation of a side of high-speed belt, and when monolateral installation, stepper motor must can be realized rotating.Corresponding sensor 12 also can adopt the mode of monolateral installation or bilateral installation, and the signal of sensor is handled and circuit control can adopt prior art to be realized.
The utility model does not relate to the part prior art that maybe can adopt same as the prior art to be realized.
In addition to the implementation, the utility model can also have other embodiment, and all being equal to replaces to technical scheme that equivalent transformation forms and all drop in the protection domain that the utility model requires.
