Description

Technical Field

[0001] The utility model belongs to the field of spinning equipment and relates to a spinning bellows. Background Art

[0002] As an important device in the spinning production process, the spinning bellows is frequently raised and lowered in daily work. Its main function is to provide a stable airflow for spinning and filter impurities in the airflow. During spinning, the air volume at the bellows outlet is adjusted by adjusting the opening of the process air valve. After the high-temperature melt is extruded from the component, it must be cooled by cooling air to be finalized. Fibers of different specifications require different cooling processes. The size of the cooling air is particularly important at this time. Too much air volume can easily cause the fiber to shake too much, break or drift, and it can also easily cause the fiber to form a skin-core structure with cold outside and hot inside, which is not conducive to winding and stretching. Too little cooling air will lead to uneven cooling of the fiber, resulting in uneven stretching during winding, which will affect uneven dyeing during fiber weaving.

[0003] Patent CN208362535U discloses a ring-blown spinning device, which includes two boxes, two air supply channels and two air inlet pipes. The two boxes are respectively provided with coaxial cylindrical filter sleeves and cylindrical filter elements that are sequentially sleeved from the outside to the inside. The surface of the filter sleeve is provided with multiple rectifying holes. The two filter elements are arranged in a vertical direction. The two are connected to each other and to the outside. The space between each box and the filter sleeve is respectively connected to an air supply channel, and each air supply channel is connected to an air inlet pipe. The air inlet pipe is provided with an air inlet regulating valve. Both air supply channels are L-shaped, consisting of a horizontal section and a vertical section. The end of the horizontal section away from the connection is closed, and the end of the vertical section away from the connection is connected to the air inlet pipe. The two boxes are respectively located above and below the horizontal section and connected to the air supply channel. The tow produced by the device is uniform in dryness and color and good in quality. However, the process air valve of the device will not be easily closed when it is stopped. Only when it is confirmed that the machine will not be started for a long time will the process air valve be manually closed, resulting in a large loss of cooling air (taking 12 holes in one spinning position and an air volume of 60m 3 / h, one stop for 20 minutes, one stop wastes 240m3 of air volume 3 ), and the cooling air is generated by the spinning air-conditioning equipment, which consumes resources such as chilled water, steam, and electricity; if the process air valve is manually closed after each stop, although it can save energy, it requires professionals to perform tedious air volume calibration when spinning (the air volume needs to be accurately calibrated in normal production, and professionals need to use professional air volume measuring instruments for calibration. Usually, when calibrating a spinning position, one person measures the wind speed in front of the bellows, and the other person adjusts the process air valve switch behind the bellows. The two people adjust the opening size of the process air valve according to the anemometer readings), which will consume manpower, extend the stop time, and reduce production efficiency.
