Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for air-spinning machines, in particular to an automatic doffing mechanism for air-spinning machines. Background Art

[0002] Air-jet spinning is a new spinning technology that uses air-jet drawing to complete spinning. After spinning is completed, it needs to be wound onto a yarn roller. When there are a lot of yarns on the yarn roller, it needs to be dropped and replaced.

[0003] For example, a Chinese patent (publication number: CN220099291U) discloses an automatic doffing mechanism for an air-jet spinning machine, comprising a fixed bracket, a fixed arm fixedly connected to the side wall of the fixed bracket, a fixed groove being provided on the front and rear side walls of the fixed arm, the fixed groove penetrating the top end of the fixed arm and the end of the fixed arm away from the side wall of the fixed bracket, a connecting spring fixedly connected to the inner side wall of the fixed groove, a connecting block fixedly connected to the end of the connecting spring, a driver fixedly provided on the side of the fixed arm close to the side wall of the fixed bracket, a push rod fixedly connected to the output end of the driver, and a push block fixedly connected to the end of the push rod away from the driver. The utility model has a simple structure and is easy to operate. It can automatically doff and replace the yarn roller, greatly improves the speed of doffing, can meet the needs of air-jet spinning, is conducive to spinning, and can store the fallen yarn bobbin into the collecting tank at the same time, so as to facilitate the removal of the yarn bobbin.

[0004] The above-mentioned automatic doffing mechanism of the air-jet spinning machine still has certain shortcomings. After the rotating shaft and the yarn roll are pushed out of the fixed groove, the fixed baffle can block the yarn roll to prevent the yarn roll from being pushed to the ground. The fallen yarn roll will fall into the collecting groove for collection. Due to the limited gap between the fixed arm and the collecting plate, it is not only inconvenient to remove the yarn roll, but also there are many yarn rolls on the collecting plate, which makes it inconvenient to remove multiple yarn rolls at one time, affecting the removal of the yarn roll after doffing and the collection efficiency. At the same time, it prolongs the collection time and easily leads to the accumulation of multiple yarn rolls. Therefore, the present application proposes an automatic doffing mechanism for an air-jet spinning machine to solve the above-mentioned problems. Utility Model Content
