自动调整隔距的梳棉机漏底结构设计

Structural design of under-screen with automatic gauge adjustment in carding machine

漏底是梳棉机上的重要部件，起到除杂、去除落棉、控制气流的作用，目前其隔距调整为手工操作，效率低且精度差。为此设计出一种可自动调整隔距的梳棉机漏底装置，用PLC控制器控制变频器驱动电动机及机械机构，以位移传感器检测隔距调整信号，实现锡林与大漏底之间、三角导流板与道夫之间的隔距自动调整，可保证实际梳理工艺中的高精度和快捷操作，满足现代高产梳棉机的要求，有效提高梳理质量和除杂效率。

The under-screen is an important part on carding machine which plays the role of opening, removal of impurity and waste, air flow control. Because of manual operation for gauge adjustment with low efficiency and poor accuracy, a new under-screen device with automatic adjustment of the gauge is developed for promoting efficiency of gauge adjustment. With PLC controller controlling two variable frequency conversion electromotor, mechanical devices and two displacement sensors for testing gauge adjustment signal, the adjustment gauges between under-screen and cylinder or triangular-screen and doffer are automatically achieved for ensuring actual carding process, under-screen availability, simple operation, reliable and stable work to meet the requirements of modern high-production carding machine, effective improvement of combing quality and removal efficiency.
