Description

Technical Field

[0001] The present application relates to the technical field of dust removal for air jet looms, and in particular to a lower dust collecting device for air jet looms. Background Art

[0002] Air jet loom is a shuttleless loom that uses jet airflow to pull the weft yarn through the shed. The working principle is to use air as the weft insertion medium, and use the ejected compressed airflow to generate friction 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. During the use of the air jet loom, cotton dust will fall on the ground below.

[0003] Patent No. CN220827533U discloses a lower dust collecting device for an air jet loom. The lower dust collecting device for an air jet loom is provided with a sliding device. When the vacuum cleaner collects cotton dust, when a certain amount is collected, the first gear is driven to rotate by the running motor, and then the first gear drives the first rack to rotate, and then the filter screen is slid into the collection shell, thereby realizing the function of collecting and moving the cotton dust. A cleaning device is also provided. When the filter screen slides into the collection shell, the first rack drives the third gear to rotate, and at the same time drives the second gear to rotate, and at the same time the second rack slides up and down, and at this time the scraper is slid to the top of the filter screen. When the filter screen is recycled, the scraper cleans the cotton dust on the filter screen, and the cleaned cotton dust is hung in the water storage box and attached to the water surface in the water storage box, thereby realizing the function of cleaning the filter screen. However, the amount of cotton dust that can be collected by the device is limited by the size of the water surface. If the water surface is filled with cotton dust, the cotton dust will no longer be able to adhere to the water surface and will float under the influence of the air flow. There is a possibility that the cotton dust will float out of the device. Therefore, the staff needs to replace the water storage box regularly, which will affect the working time of the loom and reduce the working efficiency of the loom. Utility Model Content
