Abstract
The utility model discloses a main jet accelerating device which comprises an auxiliary main jet device and a main jet device, wherein the auxiliary main jet device comprises an auxiliary main jet pipe, the main jet device comprises a straight-through jet core and a flexible pipe, one end of the flexible pipe is connected with the auxiliary main jet pipe, and the other end of the flexible pipe is connected with the straight-through jet core. In the utility model, a closed channel for air flow to pass through is formed between the auxiliary main spray nozzle and the straight-through spray core. The air flow ejected from the auxiliary main nozzle enters the flexible pipe and then enters the straight-through nozzle core. Because the flexible pipe forms a sealed channel of the airflow, the airflow jetted from the auxiliary main jet nozzle can not be emitted, so that the energy is saved, and the production cost is reduced. In addition, because the weft yarns are isolated in the flexible pipe, in the starting-up stage, even if the weft yarns swing along with the main spraying device, the adjacent weft yarns cannot interfere with each other, so that the starting-up efficiency is improved. The utility model also discloses an air jet loom.
