8. one according to claim 6 utilizes photoelectricity gate-type multi-compartment tube grinding machine swollen tripe checkout gear to carry out pre-swollen tripe regulate and control method, it is characterized in that: described detection head (4) bottom is cylinder, detection head (4) lower end is through hollow cylinder (5) bottom, detection head (4) top is cone, cone top is provided with the connection thin slice (6) connecting hollow cylinder (5), and plate (8) is vertically fixed on and connects thin slice (6) upside;
The concrete grammar of the time T that record detection head (4) is in material (7) is: when not having material (7) to apply pressure to detection head (4) lower end, connection thin slice (6) center of detection head (4) does not have pressure, connect thin slice (6) and do not produce displacement, plate (8) does not also produce displacement, the optical signal launched of photoemission module (16) is sent to hole opto-electronic receiver module (17) by logical on plate (8), opto-electronic receiver module (17) is in normal condition, and testing circuit (10) no signal produces, when there being material (7) to apply pressure on the cylinder of detection head (4) lower end, detection head (4) lower end cylinder is delivered to pressure the center connecting thin slice (6) by top conical body, pressure is born and bulging deformation in center, deflection makes plate (8) produce displacement, the optical signal launched of photoemission module (16) cannot be sent to hole opto-electronic receiver module (17) by logical on plate (8), opto-electronic receiver module (17) voltage changes, testing circuit (10) has the signal of telecommunication to produce, testing circuit (10) by electrical signal transfer to signal processing module and change into data signal export, the time simultaneously recording data signal generation is T, then T is the time that detection head (4) is in material (7).
