Description

Technical Field

[0001] The utility model relates to the technical field of air jet looms, in particular to an air jet loom heald frame with a self-cleaning function. 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, bring the weft yarn through the shed, and achieve the purpose of weft insertion through the jet generated by the air jet. This weft insertion method can enable the loom to achieve high speed and high production. Among several shuttleless looms, the air jet loom has the highest speed. Due to its reasonable weft insertion method, high weft insertion rate, simple and safe operation, wide variety adaptability, low machine material consumption, high efficiency, high speed, low noise and other advantages, it has become one of the most promising new cloth looms.

[0003] However, the existing jet loom needs to be equipped with a heald frame for wiring when in use, so that during the production process, various hair scraps and other debris will be adsorbed on the heald frame, thereby affecting the use of the heald frame. There are two existing ways to remove hair scraps. One is to stop the machine for overall cleaning, which wastes working hours. The other is to use a scraper to clean the surface of the heald frame by moving up and down during production. After the scraper is cleaned, the cleaned garbage will remain on the scraper. Although the heald frame is cleaned, the scraper itself will accumulate more hair scraps and other debris over time, and it also faces the same dilemma as the heald frame and needs to be stopped for cleaning.

[0004] Therefore, we propose an air jet loom heald frame with self-cleaning function to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a jet loom heald frame with a self-cleaning function. When the cleaning structure is used, the utility model adopts the same method as the scraper to move the quick-drying scraper up and down during production to contact the surface of the heald frame to clean up attached waste debris and other debris. During the cleaning process, the debris will move with the up and down movement of the quick-drying scraper, thereby falling or adhering to the quick-drying scraper. After the heald frame is cleaned, the quick-drying scraper can fall into the embedded groove, and an inclined nozzle is installed in the embedded groove. The surface of the quick-drying scraper can be sprayed and washed in a high-pressure washing manner, so that after a single cleaning, the quick-drying scraper can still remain clean, and more waste debris and impurities can be scraped off during the next cleaning to improve the cleaning effect each time, improve the cleaning efficiency, avoid the need for secondary cleaning of the quick-drying scraper, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A jet loom heald frame with a self-cleaning function comprises a loom case and an air gun, wherein a cleaning structure for cleaning the heald frame during the production process is installed at the upper end of the loom case; the cleaning structure comprises a heald frame body arranged on one side of the loom case, a shuttle plate is arranged at the middle end of the heald frame body, electric screws are arranged at both ends of the shuttle plate, a threaded block is threadedly connected to the outer wall of the electric screw, and an installation box is arranged at one end of the threaded block, an embedded slider is arranged inside the installation box, an electric threaded rod is threadedly connected to the inner wall of the embedded slider, and a quick-drying scraper is also installed at one end of the embedded slider.

[0008] In a further embodiment, a plurality of the shuttle thread plates are arranged in the main body of the heald frame, and electric screws are arranged on both sides of a single shuttle thread plate, and two relatively arranged quick-drying scrapers are also symmetrically arranged.

[0009] In a further embodiment, the quick-drying scraper is installed at the front end of the shuttle thread board, and the gap between two adjacent quick-drying scrapers is set according to the distance of the thread passed by the shuttle thread board, that is, the length of the quick-drying scraper.

[0010] In a further embodiment, the heald frame body is embedded and installed inside one side of a loom case, and an embedding groove is provided on the outer wall of the heald frame body.

[0011] In a further embodiment, the embedding groove has a width consistent with that of the installation box, and the installation box is inserted into the embedding groove via an electric screw.

[0012] In a further embodiment, an inclined nozzle is arranged inside the embedding groove, the inclined nozzle is oriented toward the quick-drying scraper, and a limit plate is arranged at one end of the inclined nozzle, and the electric screw is movably inserted in the limit plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model adopts the same method as the scraper when using the cleaning structure. The quick-drying scraper is moved up and down during production to contact the surface of the heald frame to clean up the attached waste debris and other debris. In the cleaning process, the debris will move with the up and down movement of the quick-drying scraper, thereby falling or adhering to the quick-drying scraper. After the heald frame is cleaned, the quick-drying scraper can fall into the embedded groove. An inclined nozzle is installed in the embedded groove, which can spray the surface of the quick-drying scraper in a high-pressure flushing manner, so that after a single cleaning, the quick-drying scraper can still remain clean, and more waste debris and impurities can be scraped off during the next cleaning, so as to improve the cleaning effect each time, improve the cleaning efficiency, and avoid the need for secondary cleaning of the quick-drying scraper.
