Abstract

The invention relates to an automatic creel lifting device of a rotor spinning machine. The automatic creel lifting device of the rotor spinning machine is characterized in that the device comprises an installation base, a yarn carrying rod piece, a first spring, a lifting arm, a first electromagnet, a lifting arm cam and a supporting arm, the yarn carrying rod piece is provided with a connecting arm, a yarn carrying rod part and a rotary shaft part, the rotary shaft part is installed on the installation base in a rotary mode, the first spring is connected between the installation base and the connecting arm, the lifting arm is fixed on the end portion of the rotary shaft part, the first electromagnet is fixed on the lower portion of the lifting arm, a first bearing is installed on the end portion of an iron core of the first electromagnet, the lifting arm cam is fixed on the rotary shaft, and the middle of the supporting arm is connected to the installation base in a rotary mode. According to the automatic creel lifting device of the rotor spinning machine, when a yarn breaking signal is transmitted to the first electromagnet, the first bearing is made in contact with the lifting arm cam rotating along with the rotary shaft, the movement of the lifting arm cam enables the lifting arm to deviate, then the whole yarn carrying rod piece is driven to deviate upwards to lift a creel, and then the automatic yarn lifting function of the creel is achieved.

Description

technical field

[0001] The invention belongs to the technical field of spinning machinery and equipment, and in particular relates to an automatic creel lifting device of a rotor spinning machine. Background technique

[0002] The rotor spinning machine is a new type of spinning equipment with rapid development. The yarn drawing speed and spinning count are getting higher and higher. The manual yarn lifting currently used is labor-intensive. The starting of the yarn will make the yarn rub against the winding roller all the time, which is easy to wear the yarn, and the efficiency is poor.

[0003] At present, the semi-automatic piecing device of the rotor spinning machine on the market uses the force generated in the closed state of the electromagnet to drive the top roller and the yarn delivery shaft to prepare for the piecing through the locking linkage mechanism. For example, a Chinese utility model patent "A New Semi-automatic Jointing Mechanism for a Rotor Spinning Mach...
