Abstract

Provided are a device and method for cutting straw.A travel switch is arranged on the left side of a notch of an accommodating groove, and a pair of active infrared intrusion detector switches is arranged on the two sides of the position of the notch of an accommodating groove.After a cutter is lowered to the notch of the accommodating groove, the speed is lowered, so that the risk of damaging operators' hands by the cutter is lowered.The rising speed of the cutter is quicker than the descending speed, and the operation time is saved.A pair of second active infrared intrusion detector switches is arranged at an endpoint of a short shaft of a cam and a knife rest.Only when the cutter rises to the highest position can the motor stop rotating, so that it is guaranteed that the cutter returns.

Once complete straw cutting process is as follows:
(1) straw is put into holding tank;
(2) pressing starting switch, control unit controls electric motor starting so that the second sprocket wheel turns clockwise with First Speed, and cutting knife declines;
(3) when cutting knife arrives the described notch place of holding tank, blocking the infrared emission signal of described first infrared emission switch, the first infrared emission switch sends signal to control unit;
(4) control unit controls motor running so that the second sprocket wheel turns clockwise with second speed, and cutting knife continues the cutting straw that declines, and second speed is the half of First Speed;
(5) knife rest touches travel switch, and travel switch sends signal to control unit;
(6) control unit controls motor running so that the second sprocket wheel rotates counterclockwise with third speed, and cutting knife rises, and third speed is 3 times of second speed;
(7) when the major axis of cam and short axle go to vertical position, and major axis above short axle time, cutting knife arrives extreme higher position, and the second infrared emission switch receives infrared emission signal, and the second infrared emission switch sends signal to control unit;
(8) control unit controls motor stalls。
The invention have benefit that: both sides, (1) holding tank notch place are provided with a pair first infrared emission switches, and after cutting knife drops to accommodation notch, speed reduces, and reduces the risk of the hands of cutting knife incised wound operator;(2) speed that cutting knife rises is faster than the speed declined, and saves the activity duration;(3) being provided with a pair second infrared emissions switches on the end points of the short axle of cam and knife rest, when only cutting knife rises to extreme higher position, motor just stops operating, it is ensured that cutting knife reset。
