Here the pressure gauge directly affects the size of the leak at the bottom. Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery. According to the spinning process, carding is an important process.
The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process). During the spinning process of the spinning frame, the semi-finished roving or sliver is drafted, twisted, and wound into a spinning machine. The combed sliver and the needle-carding machine combine the sliver, the needle row is drafted to improve the sliver structure, and the roving is further spun into spun yarn on the ring spinning frame, which is the main spinning machine. Special equipment for the textile industry on the winder.
As the last process of spinning and the first process of weaving, winding is the link between the past and the next.“bridge”Therefore, it occupies an important position in the textile field. This gap should meet the requirements of a Chinese enterprise: make the pressure of the development space above and below the gap between Xinjinlong and the licker-in roller slightly larger than the stress in the bottom of the large and small leaks, and make the pressure problem below the nose tip of the bottom of the big and small leaks gradually begin Drop rather than abruptly on its own so that the airflow out of the scupper mesh or aperture can be as moderate as possible. When the distance between the nose tip and the Jinlin width is large, the pressure at the bottom of the leak can be slightly relieved, but the pressure above the nose tip rises rapidly, the pressure on both sides of the needle tip and the bottom of the roller rises, and the cotton drop increases.
The same happens when the distance between the nose tip of the large funnel and the licker-in is too great. At this time, although the licker-in can take away most of the airflow at the bottom of the licker-in, due to the large airflow density between the cylinder and the licker-in, the air pressure between the licker-in and the small leakage roll increases accordingly, resulting in the front end of the licker-in. Pressure increases. Therefore, the air pressure in the large and small leak bottoms is related to the distance between the nose tip of the large leak bottom and the Xinjinlong and the licker-in, and the sum of the two distances should be slightly smaller.
However, the air velocity driven by the licker-in roller is less than that of the surface layer of Xinjinlong. Therefore, the distance between the nose tip of the big leaky bottom and the licker-in can be slightly larger than the distance between the nose tip of the big leaky bottom and the Xinjinlong. General enterprises use the following spacing: the large end of the drain cylinder - 0.56mm bottom tip ~ nail roller 1.00mm.
