Son-mother trolley doffer six-connecting-rod guiding track abutting connection self-locking mechanism

Abstract

The invention belongs to the technical field of ring spinning doffing equipment and discloses a son-mother trolley doffer six-connecting-rod guiding track abutting connection self-locking mechanism which comprises a base, three connecting rods, a swinging rod, a stirring rod, six shafts, three spring pieces and a protruding block. A six-connecting-rod mechanism, a long groove, an L-shaped groove, the spring pieces and the like are used, guiding track abutting connection and self-locking functions are achieved in a comprehensive mode, the mechanism is used in an automatic doffing device which is in a son-mother trolley form and can be adaptive to the heights of upper guiding tracks of spinning frames with different specifications, a horizontal guiding track of a doffing mother trolley and an upper guiding track of a spinning frame are aligned, a doffing son trolley can walk to the upper guiding track of the spinning frame in a smooth mode from the horizontal guiding track of the doffing mother trolley, meanwhile, the doffing mother trolley is fixedly connected with the spinning frame temporarily, when the doffing son trolley completes doffing and is backed to enter the doffing mother car, fixing connection of the doffing mother trolley and the spinning frame can be removed automatically, the mechanism can be restored to the initial state, and reusing is convenient.

Description

technical field [0001] The invention belongs to the technical field of ring spinning doffing equipment, and in particular relates to the structural design of a six-link guide rail butt joint self-locking mechanism of a mother car doffer. Background technique [0002] The automatic doffing device is a necessary device in the spinning process. This device can replace manual doffing, reduce labor intensity, and improve labor efficiency. With the rising labor costs in recent years, the use and optimization of automatic doffing devices is more urgent important. [0003] The automatic doffing device generally has the functions of automatic walking, doffing, intubation, and reversing. Because the device has many functions, the structure is relatively complicated, and the actions of walking, yarn pulling, and intubation have a great impact on the strength and There is a higher requirement for stiffness, making the device heavier. When the traditional automatic doffing device is on...
