Abstract:In order to improve the running stability and reliability of JWF1381 draw frame and lap machine combined，how to solve the automatic cycle failure of automatic doff system by paying attention to the manual operation function and defects in the program design，avoiding the wrong connection of control pneumatic cylinder gas pipe，adjusting the gap between near-switch and induction plate，ensuring the good condition of near-switch，eliminating the failure of solenoid valve and electronic proportional valve，etc.,are described.The measures to solve the pneumatic cylinder failure by replacing the sealing ring of the disc pneumatic cylinder and adjusting the pneumatic speeder throttle valve are expounded.The technical points of reforming the electromagnetic clutch, the draft pressure part and the clamping detection mechanism of the draw frame and lap machine combined are introduced.It is pointed out that the use of dry single plate electromagnetic clutch instead of multi-plate electromagnetic clutch，has no residual torque，and is fast clutch action response，simple assembly and maintenance，good heat dissipation and stability.A near-switch is installed on the left protective cover of the front and rear dr-afting devices of the draw frame and lap machine combined，which can solve the problem that the pressure hook can be driven without hanging the pressure pin shaft and there are overweight cotton rolls.The near-switch of the bobbin clamping detection mechanism of the draw frame and lap machine combined is tied to the retaining joint connected with the lifting arm with an easy pulling strap.At the same time，the gap between the left and right disc near-switch and disc is adjusted to 2 mm，which can reduce the labor intensity of workers and reduce the stop rate caused by equipment failure.Equipment personnel should master the operation essentials of pneumatic transmission control system of equipment，fault diagnosis skills and troubleshooting in time.
Key Words:draw frame and lap machine combined；electromagnetic clutch；draft pressure；clamping detection；solenoid valve；near-switch；pneumatic cylinder；electronic propotional valve
