Technical scheme of the present invention is: the checkout gear of jet loom for drawing weft yarn system, comprising: matrix, measuring head, ranging rod, Pressure gauge, location-plate, special-shaped reed, pilot jet, bolt, appendix, groove, airflow hole, reed groove, pilot jet seat; It is characterized in that: on matrix, in end face airflow hole, Pressure gauge is housed, the lower end of airflow hole is connected with the measuring head in being contained in lower end, matrix left side screw, and measuring head is fixed in the screw of end front side, matrix lower-left, and measuring head front end is concordant with matrix bottom surface; One end riveted joint of ranging rod is fixed on the bottom face of matrix left side, is positioned at after measuring head; Matrix is provided with adjusting screw, bolt is inserted into and regulates in screw, screw on location-plate is sleeved on bolt, screws nut on bolt the location-plate that is provided with boss is installed to the upper end that is fastened on the matrix back side, makes to form groove between boss on location-plate and matrix; The upper end of abnormity reed is inserted in the boss and the groove between matrix on location-plate, and the lower end of special-shaped reed is inserted in the groove on pilot jet seat; Measuring head is deep in the reed groove on special-shaped reed, and pilot jet is contained on pilot jet seat, and pilot jet upper end contacts with matrix bottom groove, and nozzle lower end is connected with a termination of appendix.
The air pressure mean value 100-120mbar of air-flow, air pressure maximum 250mbar, the maximum adjacent difference < 20mbar of boundary and standard deviation value ± 10mbar in Profiled Reed reed groove of the present invention; By adjusting pilot jet spacing position, angle, gas circuit state and maintenance electromagnetic valve make assistant nozzle jet air flow atmospheric pressure value on machine reach ideal data.Under the test pressure 0.5 ± 0.05MPa of regulation, the air pressure in reed groove, little 10-20mbar is answered in fluctuation, along omnidistance reed, is growing planted agent's uniformity.Thereby obtain, adjust pilot jet spacing position, angle, gas circuit state and maintenance electromagnetic valve make assistant nozzle jet air flow atmospheric pressure value on machine reach ideal data.
The present invention can by regulating screw and adjusting bolt, adjust location-plate up and down for highly different Profiled Reed, increases or reduce the mounting distance of special-shaped reed, guarantees that special-shaped reed installation site is correct; The front of matrix hangs on reed beam, and matrix can slide left and right on reed beam.
Invention beneficial effect:
1, matrix meets the hump shape of Profiled Reed, and inside is provided with airflow hole (air-flow paths), effectively invisible point is become to visible point.
2, measuring head is contained on the matrix of pressing close to reed groove most and can checks the force value of pressing close to reed trench bottom point-assistant nozzle air current application point in Profiled Reed groove.
3, the scope of application of the present invention is extensive, not only can adjust test point position according to the special-shaped reed of different size, also can the different nozzle of detected pressures type.
