Abstract
The invention discloses a stepless-regulation airflow-mechanical cellosilk spreading mechanism. The stepless-regulation airflow-mechanical cellosilk spreading mechanism comprises a driving cellosilk unwinding roller, a driving cellosilk winding roller and two tensioning wheels, wherein the driving cellosilk unwinding roller and the driving cellosilk winding roller are driven by a motor, and the two tensioning wheels are matched with the driving cellosilk unwinding roller and the driving cellosilk winding roller respectively. The stepless-regulation airflow-mechanical cellosilk spreading mechanism further comprises a mechanical cellosilk spreading mechanism and an air extractor, wherein the mechanical cellosilk spreading mechanism is arranged between the two tensioning wheels, and the air extractor is connected with the mechanical cellosilk spreading mechanism. According to the stepless-regulation airflow-mechanical cellosilk spreading mechanism, the stepless speed regulation motor is adopted to output different stable rotation speeds to drive a cam swing rod mechanism to mechanically spread cellosilk. The tension of cellosilk bundles can be adjusted in the cellosilk spreading process through the driving cellosilk unwinding roller and the driving cellosilk winding roller. With regard to the air extractor, a centrifugal blower is used as a negative pressure source to achieve the purpose of spreading cellosilk through airflow. In this way, the cellosilk bundles can be effectively and evenly spread; in addition, the surface quality of the cellosilk bundles is guaranteed, the problems that current mechanical cellosilk spreading is low in effectiveness and high in rejection rate are solved, and the stepless-regulation airflow-mechanical cellosilk spreading mechanism is convenient and flexible to operate.
