Design Technology of Strip Coil Mechanism for Opener

During the spinning process on the opener, the top of the sliver or wool forms a certain return stroke and is regularly placed in the barrel for the next process. The mechanism that completes the formation of the coil is called the coiling mechanism of the opener. In the production of the opener, in order to improve labor productivity and equipment utilization, a large-diameter cylinder is used, requiring a large volume of products to be accommodated in the geometric space formed by a certain winding size. Due to the loose structure of the bag, the fiber clamping force is small, and the strength of the sliver is low. If the sliver is subjected to a large tension when winding or drawing out the sliver, it will cause accidental drafting or breakage. Therefore, in addition to the above requirements, it is also necessary to correctly form the coil strip, distinguish the layers, and prevent the strips from winding with each other. In cotton spinning production, the sliver products of the opener are usually stored in the jinkawa through the sliver coiling in a cycloidal orbit. After being compressed by the small pressure roller 2, the sliver enters the sliver 4 through the inclined tube 3 of the coiling and is stored in the barrel in a certain shape. The return disk rotates at a constant speed, and the trajectory of the sliver output by the inclined tube in the space is circular. However, due to the eccentric distance E between the coil and the sliver, and the sliver barrel rotates at a constant speed, the relative trajectory of the sliver in the sliver is linear, and an air hole is formed in the center of the sliver barrel. When the strip size is fixed, if the eccentricity e value is changed, the strip shape can be divided into small strip and large strip. The design of the opening machine mechanism should meet the following process requirements: (1) The formation of the coil strip is normal, that is, the air holes in the strip can be connected within the entire height, and the solid layer is clear. The two adjacent coils of slivers are arranged closely without overlap, and the slivers can be smoothly led out in the next process. (2) The brocade belt roll leather has a large volume, which reduces the secondary convergence of the barrel change and improves labor productivity. The above mainly introduces the design process of the coil mechanism of the opener, I hope it can help you!
