Spool lifting mechanism

Abstract

The invention discloses a spool lifting mechanism. The spool lifting mechanism is characterized in that a cam driven mechanism is used for driving a lifting supporting plate to longitudinally move toachieve lifting of a supporting cradle frame, an electromagnet is used for driving the lifting supporting plate to transversely move to achieve fit and separation of a cam driven part and a disc cam,an iron core rod of the electromagnet is sleeved with a spring to drive the lifting supporting plate to do transverse reset moving, the lifting supporting plate and the top end of an electromagnet mounting plate are rotatably connected with a cradle frame side plate through pin shaft supports, in the axial direction of a pin shaft, the electromagnet mounting plate cannot move relative to the cradle frame side plate, the electromagnet is mounted on the overhanging bottom end of the electromagnet mounting plate, the iron core rod of the electromagnet is connected with the lifting supporting plate, the disc cam is supported by a supporting rotating shaft to rotate, the cam driven part is arranged in the middle of the lifting supporting plate and synchronously moves along with the lifting supporting plate, the lifting supporting plate is moved, limited and guided through a limiting guide mechanism, and the problems that an existing spool lifting mechanism damages yarn, affects yarn tensionand needs additional air source energy consumption are solved.

Description

technical field [0001] The invention belongs to the field of yarn manufacturing equipment, and in particular relates to a yarn bobbin lifting mechanism. Background technique [0002] The winding mechanism of yarn manufacturing equipment such as twisting machine, spinning frame, and doubling machine includes a cradle for clamping the bobbin and a friction roller for driving the bobbin to rotate. The cradle mainly consists of two side plates and a rear plate. The end connection is U-shaped. The rear plate is supported and installed by the cradle shaft. The cradle can swing around the cradle shaft. The friction roller is installed on the friction roller installation shaft driven by the motor. The friction roller installation shaft is controlled by the machine. The bracket is set to the shaft hole support installation. When working, the two ends of the bobbin are supported and clamped by the side plates of the cradle, the yarn is wound on the bobbin, and the bobbin is pressed a...
