The dust removal knife part includes: the inlet part of the front end of the small leak of the card feeding plate, and the main part of the parking clutter. 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.
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. 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). After the carding between the licker-in and the feeder, part of the fibers and impurities can be attached to the sawtooth, and another important part is on the surface of the sawtooth structure or floated in the airflow through the study of fibers and impurities.
The influence of air flow on the boundary layer increases with the rotation of the licker-in, the fibers and impurities floating in the air flow increase gradually, and there are also large impurities and defects at the final processing speed. Differences in development trajectories tend to flow to the outside of the boundary layer. It was found that, except at the inlet of the cotton and receiver tip plates, the rest of the flow velocity distribution was substantially consistent with the boundary layer theory as evident. Based on the test licker-in performed cover removal or reduction in cover G, the car belly pressure roller cylinder is reduced to less significant loss of cotton fibers, which means that the inflation pressure of the cover card licker-in keeps fibers away from the licker-in teeth and easily noils Increase.
The gas flows to the cover caused by high pressure, passing through the tooth gap, changing the flow rate, and the distribution of fibers and impurities falling along the flow direction. This airflow control is detrimental to noil and it is considered necessary for mulching improvement. Fibers and impurities do not float in the boundary layer from the beginning at point A, otherwise we will develop a clear boundary for students to compare and analyze, that is, impurities are in the outer layer and fibers are in the inner layer.
If it is through this, it is very simple and easy to control the impurity removal. The loss of fibers is unavoidable, and it is necessary to explain that Chinese fibers and impurities are mixed and distributed to a certain extent, that is, they do not float in the boundary layer at the same point of use. Such a movement path of fibers and impurities can also affect the economical staggering and detrimental removal of impurities.
Since there is no impurities and it is easy to float due to the surface of the licker-in, the impurity content of the noil is high. In the licker-in section of the card, these social relations are not clearly defined. It can be imagined by yourself that if the working environment of the licker-in is very favorable for the separation of impurities, and the licker-in can start to detach from the surface of the sawtooth structure as soon as possible at point A, the research will be beneficial to the improvement of the impurity removal efficiency and the waste content of waste.
The working and living conditions of these enterprises mainly include the acceleration of improving the speed of department-level management, the change of the angle of the saw window and the smooth and sharp surface, and the reasonable and effective adjustment of the length of the carding point of the cotton board. In order to control the air flow, the adjustment of the dust removal knife includes three aspects: the distance of the dust removal blade, the height of the dust removal blade and the installation angle of the dust removal blade, which generally refers to the angle between the back of the dust removal blade and the horizontal line. Among them, the dust removal knife has a greater impact on the cotton droplets.
