However, the existing silk -sucking device has the following problems:

[0003] 1. uneven suction distribution: the traditional silk -sucking air port is single -port design, and the suction force is concentrated, so that the waste silk in some areas cannot be effectively adsorbed, and the collection efficiency is affected.

[0004] 2. single design of silk -sucking port: the shape and structure of the silk -sucking port have important influence on the silk -sucking effect, but at present, the silk -sucking port is mostly circular or simple linear shape, which cannot fully cover the waste silk distribution in a wide range.

[0005] 3. inconvenient operation adjustment: in the actual collection process of waste silk, due to the different types of waste silk, distribution area and operation environment, the angle and suction force of the silk -sucking port need to be adjusted, but the existing equipment lacks convenient adjusting structure, which affects the use flexibility.

[0006] 4. low waste silk collection efficiency: for the long silk or curled silk that is easy to wind, the existing device often has the problems of poor silk -sucking or blockage, which increases the maintenance workload. INVENTION CONTENTS
