Description

Technical Field

[0001] The utility model relates to the technical field of knitted fabrics, in particular to a yarn blowing and hair removal mechanism for knitted fabrics. Background Art

[0002] Knitted cloth is a fabric formed by bending yarn into loops and interlacing them with knitting needles. It is divided into warp knitted cloth and weft knitted cloth. Knitted cloth is woven by a knitting machine. During the weaving process, the yarn guiding structure needs to blow away the yarn fluff generated when the yarn passes through, to prevent the yarn fluff from falling on the knitting structure and being knitted into the knitted cloth, causing the quality of the knitted cloth to deteriorate. However, it still has the following disadvantages in actual use. When the existing yarn blowing and dehairing device for knitted cloth processing is in use, the yarn fluff can only be simply blown away from the knitted cloth by wind force, and the blowing position of the airflow cannot be adjusted, resulting in poor applicability of the yarn blowing and dehairing device. When the existing yarn blowing and dehairing device for knitted cloth processing is in use, the yarn fluff can only fall directly on the ground, which is troublesome to clean and cannot be conveniently cleaned. Patent documents have been made to improve this.

[0003] For example, Chinese patent CN220116793U discloses a yarn blowing and dehairing device based on knitted fabric processing, including a support cylinder, a support plate and a rotating motor. A turntable is provided at the top of the support cylinder, and a pair of support plates are symmetrically fixed on the top surface of the turntable. The hydraulic cylinder includes a base cylinder body and a hydraulic rod. The mounting seat includes a swivel seat hinged to the support plate, which is used to fix the connecting seat of the rotating motor. The bottom end of the cylinder body is hinged to the support plate, and the end of the hydraulic rod is hinged to the connecting seat. The hydraulic cylinder is located on the lower side of the mounting seat to adjust the pitch angle of the rotating motor. The soft collection shell surrounds the outer periphery of the rotating motor, and air holes are evenly opened on the surface. The pitch angle of the rotating motor can be adjusted by the hydraulic cylinder, and the yarn fluff on the yarn on the knitting machine can be comprehensively blown to the soft collection shell with four circles around it, so as to facilitate the collection of the yarn fluff.

[0004] Although the above patent can comprehensively blow the yarn fluff on the yarn on the knitting machine to the soft collection shell with four circles, so as to facilitate the collection of the yarn fluff, when cleaning the yarn fluff, it needs to be driven by multiple driving sources, especially additional hydraulic cylinders are needed to adjust the pitch angle of the rotating motor, resulting in high cost of use.
