A weft feeder for weft processing of air-jet loom

Abstract

The invention discloses a weft feeder for weft processing of an air-jet loom, which comprises a motor, a motor protection case, a yarn winding disc, a yarn storage drum and a yarn clearing device. A heat dissipation groove is arranged on the top surface of the motor protection case to dissipate heat. A filter device is arranged in the tank, and a dust-proof device is arranged above the filter device. The dust-proof device includes a mounting plate and a dust-proof cover. The components include heat-absorbing pipes and heat-dissipating pipes. The invention has simple structure and strong practicability. By changing the heat dissipation mode of the original heat sink type, the heat dissipation effect of the weft feeder is improved, and the service life of the weft feeder is prolonged. At the same time, the design of the yarn clearing device , through the dual combination of the brush and the yarn scraping plate, the cleaning of the yarn storage drum is more convenient, effectively preventing the weft yarn from breaking due to excessive friction during use, and improving the comprehensive utilization efficiency.

Description

technical field [0001] The invention relates to a weft feeder for weft processing of an air-jet loom. Background technique [0002] The air-jet loom is a shuttleless loom that uses jet air to pull the weft through the shed. The working principle is to use the air as the weft insertion medium, and use the compressed air jet to generate friction and traction on the weft yarn to pull the weft yarn through the shed, and achieve the purpose of weft insertion through the jet generated by the air jet. However, if the weft yarn is directly unwound by the air-jet loom, the peak value of the weft yarn tension will be too large, and the weft yarn will easily break, which not only increases the loss of energy consumption, but also reduces the production efficiency. Therefore, weft feeders need to be used in the weft processing of air-jet looms. [0003] Among the basic components of the weft feeder, the quality of the cooling device and whether the structural design is reasonable have...

AI Technical Summary

Problems solved by technology

The heat dissipation devices of the existing weft feeders on the market generally use heat sinks. Although the installation structure of the heat sink is simple, the heat dissipation effect is not obvious, and the heat sink is easy to damage the power board of the weft feeder during use, thereby affecting overall production efficiency

Moreover, the existing yarn storage devices generally do not have a yarn clearing device. After the weft storage device has been used for a period of time, the surface of the yarn storage drum will stick to dander, dust, etc., which will increase the friction between the weft yarn and the yarn storage drum. , not only will reduce the quality of the woven cloth, but also the weft yarn is prone to breakage during use, which increases the cost
