The fixed dust suction port 5 can be arranged in nearby areas where the equipment cleaning frequency is relatively high, the dust volume is relatively concentrated, and the dust volume is large, such as the two ends of the belt conveyor of the distribution crane and its blanking port, the two ends of the silk storage cabinet and its blanking port, etc. One or more actuators can be set. When a certain area needs to be cleaned, the actuator can be inserted into the fixed dust suction port 5 set in the corresponding area to achieve plug-and-play, and ensure that the connection is well sealed and does not leak air. The negative pressure generated by the fan 3 transfers the dust through the actuator, the fixed dust suction port 5, the branch pipe 4 and the main pipe 2 in sequence to the dust collecting hopper 1, forming an effective negative pressure cleaning system that can effectively collect dust in the silk storage room of the silk-making workshop, thereby keeping the workshop clean, reducing the impact on workers' health, and improving production efficiency.

[0024] Furthermore, in specific implementation, a flow meter 7 is provided on the above-mentioned tube and each branch pipe 4 provided in the embodiment of the utility model, which can monitor the air flow in real time, thereby facilitating the evaluation and adjustment of the system performance, ensuring the effect of air circulation, and also providing data support for subsequent maintenance.
