Description

Technical Field

[0001] The utility model relates to the technical field of dust collecting devices, in particular to a lower dust collecting device for a corduroy air jet loom. Background Art

[0002] The corduroy air jet loom is a special loom used to produce corduroy fabric. Corduroy is a fabric with a fluffy texture and soft feel, usually used to make clothing, household items, etc. The air jet loom uses high-pressure air to send the weft into the gap of the fabric and push the warp to form the fabric. Since corduroy will produce a large amount of fabric debris and fiber impurities during the operation of the air jet loom, if it is not cleaned in time, it will affect the normal operation of the loom and even affect the product quality. Therefore, it is usually necessary to set a dust collection device at the bottom of the air jet loom to collect the impurities generated during the production process, keep the environment around the air jet loom clean, and reduce interference with the operation of the air jet loom.

[0003] When the lower dust collecting device of the corduroy jet loom currently on the market is in use, the larger fiber impurities and dust are initially filtered through the set filter plate. After a long period of use, the existing lower dust collecting device of the corduroy jet loom needs to regularly disassemble the filter plate to clean the surface of the filter plate. The cleaning process is relatively cumbersome. Therefore, we need to propose improvements to the current lower dust collecting device of the corduroy jet loom. Utility Model Content

[0011] Preferably, a second spring is sleeved on the outer side of the guide rod, and two ends of the second spring are respectively connected to the guide block and the guide groove, and a handle is connected to the upper outer side of the extension frame.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: the lower dust collecting device of the corduroy jet loom, through the cooperation between a movable cleaning brush arranged above the dust collecting hopper and a filter plate that can move up and down, facilitates regular cleaning of fiber impurities filtered by the lower dust collecting device of the corduroy jet loom, and through the retractable and movable extension frame, the dust collecting box can tightly wrap the outlet of the dust suction fan, thereby facilitating dust collection by the lower dust collecting device of the corduroy jet loom.

[0013] 1. The lower dust collecting device of the corduroy jet loom, when there are too many fiber impurities on the filter plate and the surface, the connecting block connected to the output end is driven by the starting push rod to move up along the inner wall of the dust collecting hopper and fit under the cleaning brush. At this time, the staff pushes the cleaning brush to push the cleaning brush to brush the fiber impurities filtered on the surface of the filter plate to one side to clean. After cleaning, the cleaning brush is pulled to the initial position, and then the push rod drives the connecting block and the filter plate to move down back to the initial position. The movable cleaning brush is arranged above the dust collecting hopper and the filter plate that can move up and down cooperates with each other, so that the fiber impurities filtered by the lower dust collecting device of the corduroy jet loom can be cleaned regularly;

[0014] 2. For the lower dust collecting device of the corduroy jet loom, the staff presses the extension frame downward to the limit position by holding the handle. At this time, the extension frame and the dust box are misaligned with each other. Then the dust box is placed inside the box body, and the extension frame that is pressed downward is loosened. The loosened extension frame and the guide block can automatically reset upward and fit to the inner wall of the box body through the elastic force of the second spring. Through the mutual cooperation between the extension frame and the dust box, the dust box can tightly wrap the outlet of the dust suction fan, thereby facilitating the dust collection of the lower dust collecting device of the corduroy jet loom.
