Description

Technical Field

[0001] The present invention belongs to the technical field of textile machinery equipment, and in particular relates to a sock mouth seaming device. Background Art

[0002] When the existing sock mouth seaming device transfers the coil from the knitting device to the seaming assembly, there are generally problems of insufficient positioning accuracy and poor grasping stability. For example, the traditional integrated transfer structure (such as the patent CN204661979U) relies on the gap of the single-needle straight-insert sewing needle, and it is easy for the coil to slip off due to mechanical vibration or assembly error, especially the failure rate increases significantly during high-frequency operation; while the flipping half-tooth rack scheme proposed in the patent CN105887325B can transfer the coil in segments, but it relies on multi-stage flipping actions, the structure is complex and the gear wear is serious, making it difficult to adapt to the high-speed production requirements. In addition, some devices use elastic gripping pieces (such as the patent CN204661971U) to grip the coil, but due to the lack of a precise positioning mechanism, the coil is unevenly stressed or misaligned during the grasping process, which in turn causes thread breakage or sock mouth deformation. At the core, the existing technology has not effectively solved the two major problems of collaborative positioning control of the split transfer assembly and adaptive adjustment of dynamic grasping force, and there is an urgent need for a transfer module and a sock mouth seaming device design scheme that can take into account high-precision positioning and flexible grasping.
