AI Technical Summary
Technical Problem
In the current double-layer fabric production process, the weft insertion nozzles are prone to clogging, which leads to a decrease in production efficiency and requires manual shutdown for cleaning, thus affecting production efficiency.
Method used
A double-layer fabric weft insertion device was designed, which uses a push component and a solenoid valve to control the gas flow. The gas is pushed into the nozzle through the air outlet to clear blockages, and a filter component is used to prevent dust from entering and avoid blockages.
Benefits of technology
It achieves automated cleaning of nozzle blockages, avoiding downtime for cleaning, and improving production efficiency and equipment reliability.

Abstract
This utility model discloses a double-layer fabric weft insertion device, including a mounting plate. An air cylinder and a weft insertion nozzle are fixedly installed inside the mounting plate. A pushing component is provided on the surface of the mounting plate. A piston plate is provided inside the air cylinder, and a sealing ring is fixedly installed inside the piston plate. The sealing ring and the air cylinder are overlapped. A one-way opening and closing component is provided inside the air cylinder. An air inlet pipe is fixedly installed at the front end of the air cylinder. The piston plate drives the sealing ring to push the air in the air cylinder into the interior of the weft insertion nozzle through the air outlet pipe, thereby cleaning the interior of the weft insertion nozzle. Moreover, the pressure of the gas entering the weft insertion nozzle can be controlled by the opening sequence of the solenoid valve, thus avoiding the situation where the weft insertion nozzle is blocked and the weft insertion channel of the weft insertion nozzle cannot be smoothly fed, affecting the production of double-layer fabric. It also avoids the need for workers to manually stop the air-jet loom for cleaning, thus avoiding the impact on the production efficiency of double-layer fabric by stopping the machine to clean the weft insertion nozzle.
