Description
Technical Field
[0001] The utility model relates to the technical field of textiles, and more specifically to a spinning frame drafting component. Background Art
[0002] The spinning frame is a textile machine that spins coarse yarn into fine yarn, and the drafting device in the spinning frame is an important part of the spinning frame. The drafting device is the process of drawing and thinning the sliver. The essence of the drafting of the drafting device is to make the fiber move relative to the axial direction, and its purpose is to draw the drawn and thinned sliver to the specified thickness;
[0003] When the existing spinning machine drafting device is drafting the yarn, before the yarn is directly fed into the roller in the drafting device through the guide roller, the yarn needs to be adjusted in the early stage for tension and flatness, so as to avoid the situation that the yarn is easily wound around the roller due to too small tension during drafting, and the yarn is easily broken due to too large tension. At the same time, the yarn surface needs to be cleaned during the early adjustment process. However, the existing spinning machine drafting components have the following problems when in use:
[0004] The yarn first needs to be introduced through the introduction roller structure, and then passes through the cleaning structure and the adjustment structure in sequence to finally complete the stretching. In this process, when adjusting the tension, the tension roller that can be raised and lowered needs to be used to contact the yarn to complete the tension adjustment. There is a distance between the tension roller and the introduction roller structure. When the tension roller acts on the yarn for adjustment, the yarn at the introduction roller structure position is in a tense state. The yarn at this position has no other buffer support structure except the introduction roller. The yarn at this position is prone to breakage and debonding. At the same time, when cleaning the yarn fluff, a vertical negative pressure adsorption mechanism is used to complete the cleaning. However, in the actual cleaning process, the yarn fluff cleaned by the horizontally introduced yarn is prone to fall directly and concentrate at the bottom of the cleaning chamber, making it difficult to clean it through this vertical negative pressure adsorption mechanism.
[0005] Therefore, the utility model provides a spinning frame drafting assembly. Utility Model Content
