The company was founded in 1998, a professional Fabric Recycling Machine Manufacturer in China.
The air flow in the licker-in part of the carding machine passes through the licker-in, and most of the cotton bundles are completely decomposed into single fiber cells. Pay attention to the role of internal airflow. 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). The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. Grinder A spinning machine that turns fiber strands into rovings.
The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame. In production, we often find out that the belly of the car is white, a large amount of spinnable fiber material is lost, the mesh of the small leak bottom is blocked (when the small leak bottom is used), the "door curtain" is hung at the entrance, the waste is too much or too little. The phenomenon of too little impurities in the noil, these problems are generally related to the airflow control system. As shown in the analysis of the figure, the high-speed licker-in carries different fibers through the point A of the gap between the feeder and the licker-in. Because the gap is small and there are cotton whiskers, the development of air flow is hindered.
Between point A and the dust removal knife, the air flow driven by the licker-in increases as the distance from point A increases. The thickening of the airflow requires the teacher to add air a under the cotton board, which has a certain supporting effect on the fibers on the licker-in. The thickened air flow reaches the dust removal knife. In some areas, the air flow b is divided by the dust removal knife and flows down the back of the knife. The impurities and a small amount of nanofibers in the cut air layer also fall from the back of the knife.
By affecting the airflow at the distance between the dust removal knife and the thorn reel, it continues to increase, and at the mouth of the small drain bottom, the airflow c whose airflow tissue thickness exceeds the gap at the inlet of the small drain bottom is divided and folded into the back of the car, with an obvious thickness. The airflow c smaller than the population gap of the small leak bottom will enter the small leak bottom. Due to the thickening of the airflow between the traditional dust-removing knife and the small leak bottom, a supplementary airflow d is generated under the knife, so the airflow lost by the back of the knife is re-supplied to the entrance of the small leak bottom by some students, forming a recovery area, so that the back of the knife falls down Some of the main fibers may directly enter the small leak bottom with the airflow. The airflow entering the small leak bottom is due to the gradual narrowing of the distance between the licker-in and the small leak bottom, and an important part of the patient's airflow e together with the short lint and dust overflows the mesh.
At the outlet of the small drain bottom, the airflow f flows to the triangle area between the thorn and the Xinjinlong, and at the exit of the large drain bottom, it merges with the airflow g driven by the Xinjinlong. It is divided into two parts, the air flow h enters the brush roller cover and is sucked by the dust suction point B, and the air flow i enters the rear cover plate and flows into the working area located in Xinjinlong and the cover plate protection. By using the measured airflow in the licker-in part, the following conclusions can be drawn: (1) No matter whether the licker-in and Xinjinlong grow at a high speed or not, the static pressure between the small drain bottom and the licker-in and between the licker-in and the licker-in cover varies from the population to the outlet Products are all about augmentation. This is because the gap between the small leak bottom and the licker-in roll gradually shrinks in China, and the airflow environment is blocked at the gap between the feeding roller and the feeding plate.
(2) If the licker-in warmer dust cover is not used, all parts around the licker-in will form a high-pressure airflow with the increase of the speed and output of the licker-in and Xinjinlong, especially the cover of the licker-in cover is the most economical. If it is too large, it forces a part of the air flow to adjust the spray downward from the acceleration information of the feed roller and the feed plate, so that some functional fibers that were originally caught by the saw window may not be able to escape from the sawtooth and become white in the process of falling. On older cards without hoods, a hypotensive treatment must be used at the same time. (3) After using the licker-in hood, the static pressure is significantly reduced everywhere, which avoids the fall of the spinnable fiber concrete.
Due to the corresponding effective reduction of noil, the noil trash content will increase. Although the amount of lint excluded from small leaks has been continuously reduced, the total amount of lint excluded can be increased instead.
