Description

Technical Field

[0001] The utility model relates to the technical field of drafting devices, in particular to a polyester fiber multi-stage drafting device. Background Art

[0002] Polyester fiber, which we commonly call "polyester", is a synthetic fiber made by chemical condensation of organic dibasic acids and diols. It is a high molecular compound. Polyester fiber needs to be stretched during the spinning process, that is, the yarn is stretched thin and elongated to make the fiber have relative displacement in the axial direction of the yarn, so that the fiber is distributed over a longer length.

[0003] According to patent publication number CN218203229U, a multi-stage drafting device for recycled polyester fiber is disclosed, including a mounting plate, a pre-stretching structure is provided on one side of the mounting plate, a second mounting seat is fixedly installed on one side of the mounting plate, a second electric push rod is fixedly installed on one side of the second mounting seat, a moving plate is fixedly installed on the output end of the second electric push rod, a drafting structure is provided on one side of the moving plate, a second gear is fixedly connected to one side of the drafting structure, an L-shaped connecting plate is welded on one side of the moving plate, a resistance piece is provided on one side of the mounting plate, and an impurity cleaning structure is movably installed on one side of the L-shaped connecting plate. The utility model facilitates the adjustment of the drafting ratio by performing multi-stage drafting on the recycled polyester fiber, and can conveniently remove impurities on the surface of the fiber during drafting. The following problems exist in the prior art:

[0004] In the above-mentioned publication number CN218203229U, when the yarn passes through the position between the two cleaning pads, under the squeezing action of the two cleaning pads, more impurities on the outside of the yarn can be removed and the impurities are cleaned by the first gear driving the disc, which leads to the phenomenon of splashing when the first gear and the disc rotate to clean the impurities, thereby causing secondary adhesion of impurities and poor cleaning effect. At the same time, since the above-mentioned publication number CN218203229U can only stretch a single polyester fiber yarn during working stretching, the efficiency is low. At the same time, since the polyester fiber yarn is in contact with the stretching wheel for a long time, it is easy for the yarn to generate a certain temperature when in contact with the stretching wheel, thereby there is a problem of possible yarn breakage.
