AI Technical Summary

Technical Problem

Existing jacquard shed machines' ventilation devices only allow the use of rectangular filters, which limits the filter surface size, making them unsuitable for highly polluted weaving environments and resulting in insufficient filtration efficiency.

Method used

The ventilation device employs a cylindrical filter and a molded polymer support. The cylindrical filter is centered on the central axis, and the support is fixed to the housing. It is in fluid communication with the enclosed operating space through multiple ventilation holes, which increases the filtration surface area and optimizes the device volume.

Benefits of technology

It improves the filtration efficiency of the ventilation device, adapts to highly polluted environments, reduces the impact on the size of the jacquard shed machine, and extends the service life of mechanical parts.

Abstract

The utility model discloses a jacquard shed machine, including casing and fixed on the casing ventilation device. The ventilation device has a fan and a support, the support defines an interior space that extends continuously from a first opening at a fixed portion to a second opening at a support portion. The fixed portion is fixed to the casing, and the first opening is aligned with the fan. A cylindrical filter is fixed to the support portion of the support. The cylindrical filter is located outside the interior space of the support and outside an enclosed operating space of the jacquard shed machine. The exterior of the jacquard shed machine is in fluid communication with the enclosed operating space through the cylindrical filter, through the second opening, through the interior space of the support, through the first opening, through a vent hole of the casing, and through the fan. The support is a molded polymer support. Thus, the jacquard shed machine has more efficient filtration performance, and the volume impact of the ventilation device is limited.
