Triangle manufacturers import the key triangle manufacturer, combing the output using cluster trumpet and small tooth groove roller, increase the holding force among the fibres, is advantageous to the article combed the strength increase. Article article circle direction to synthetic circle, the circle forming quality is better than that of CJ40 models. Suction noil short triangular flow plate edge in improving added a flanging, for better combing machine airflow control, reduce the workload of the cleanness of machinist, machinist belly than CJ40 models reflect the car clean. Man-machine dialogue with touch screen can be conveniently, and the parameters of the frequency converter can write or read through touch screen, the speed of change for the digital quantity change. Historical memory and various failure failure time accumulative total function, easy to maintenance and management. Electrical, pneumatic fittings for imported parts, such as motor using permanent magnet motor, the machine load is low, less energy consumption. Production practice and using the experience in a fleecy wool test raw cotton, we made different pliers trial spinning. Experiment shows that the increasing clamp time, combed all the CV value increases, but there is no obvious change of yarn. This is because the cylinder is variable speed comb, comb first rise speed slow down again, carding speed zui high in the central cylinder carding surface, clamp plate is held by the fiber carding force is increasing to the degression of, can avoid fiber damage. Synchronous belt wheel figure manufacture synchronous belt wheel is the main technical basis, before the design process, first you need to make a careful analysis of the process. By understanding the function of synchronous belt wheel and working conditions, the analysis precision and other technical requirements, in order to better master the structural characteristics and key technology. Below with a certain type of engine shaft sleeve synchronous belt wheel as an example, the process of synchronous belt wheel graph analysis. Shaft sleeve synchronous belt wheel ( Figure 2 - 1) In the medium temperature ( About 300 degrees) And high-speed ( About 10000 ~ 15000 r/min) Under the conditions of work.
