Description

Novel yarn roller structure Technical Field The utility model relates to the technical field of textile machinery, in particular to a novel yarn pressing roller structure. Background The yarn pressing roller is an important part in textile machinery, and is mainly used for controlling the tension, the position and the movement track of yarns and ensuring the stability and the precision of the knitting or embroidering process. The prior Chinese patent with publication number CN210287667U discloses a yarn pressing roller mechanism of a warping machine drafting device, wherein the drafting device is in a three-roller type and consists of a yarn pressing roller, a bearing seat, a brake, a sliding block, a sliding rail, a transverse supporting arm, an air cylinder seat, a limiting angle iron, a limiting bolt and a locking nut, when the yarn pressing roller ascends, the air cylinder pushes the transverse supporting arm to drive the sliding block on the bearing seat, and when the yarn pressing roller moves upwards along the sliding rail, the yarn pressing roller descends, the yarn pressing roller moves downwards under the action of the air cylinder and presses the yarn pressing roller on the two drafting rollers, yarn passes through between the contact surfaces of the yarn pressing roller and the two drafting rollers, the yarn pressing roller is driven to rotate by friction of the two actively rotating drafting rollers during drafting, the yarn is pulled out by clamping, the descending position of the yarn pressing roller can be adjusted by adjusting the limiting bolt and the locking nut, and the brake of the yarn pressing roller is braked during stopping. Above-mentioned scheme and yarn roller structure among the textile machinery under the prior art are single solid steel roll grafting on the bearing frame generally, and yarn roller surface temperature rise can be led to in the yarn roller when rotating the yarn operation to the friction, when the high temperature, easily reduces yarn roller life and leads to the fact the influence to yarn quality, to the novel yarn roller structure that lacks corresponding can initiatively cool down here, need improve and optimize.
