Directional multi-stage weft finding device for tatting

Abstract

The invention discloses a directional multi-stage weft finding device for tatting, which relates to the field of shuttle looms and comprises a large mounting wall plate, a main motor is fixedly connected to the bottom of the left side of the front end of the large mounting wall plate, a main shaft is rotatably connected to the right side of the large mounting wall plate, and a driving gear is rotatably connected to the interior of the large mounting wall plate through a bearing; the output end of the main motor is fixedly connected with the driving gear, one end of the main shaft is fixedly connected with a main shaft large gear, the main shaft large gear is located in the installation large wall plate, the interior of the installation large wall plate is rotationally connected with a multi-arm transmission large gear, a weft searching transmission braking mechanism is fixedly installed on the installation large wall plate, and a braking auxiliary ratchet wheel is arranged on the weft searching transmission braking mechanism. The weft-finding reversing mechanism has a weft-finding state and a non-weft-finding state. The device has the advantages that the braking auxiliary ratchet wheel is meshed with the main shaft large gear, so that reverse rotation of the main shaft is effectively reduced and prevented; and meanwhile, the servo motor is adopted for pushing, the reliability of the equipment is improved, and the production efficiency of the equipment is improved.

Description

technical field [0001] The invention relates to the field of shuttle looms, in particular to a directional multi-stage weft-finding device for shuttle weaving. Background technique [0002] In recent years, the technical capability level of my country's shuttle looms is steadily improving and further narrowing the gap with developed countries. Therefore, various manufacturers have higher and higher performance requirements for shuttle looms. Among them, the technical requirements of the weft-seeking action of the shuttle loom are developing towards high speed, stability and high efficiency. [0003] The weft-seeking mechanisms adopted by the shuttle looms on the market all have complex gear transmission chains, and there are various limitations such as too long transmission chains, slow weft-seeking movements, and low work efficiency. In addition, the traditional weft-seeking mechanism is provided with an independent external load in order to achieve high-speed weft-seeking...
