Traveling device of frame spinning automatic doffer

Abstract

The invention relates to a traveling device of a frame spinning automatic doffer, belonging to the technical field of frame spinning doffing equipment. The traveling device comprises a base, a motor, a driving shaft, a driven shaft, a driving wheel, a driven wheel, a transmission piece, a guide rail and a plurality of stretching units. The device utilizes the motor to drive the stretching units to continuously move through a transmission mechanism, simultaneously utilizes the guide rail to realize sliding bar stretching, and utilizes a dialing block to dial a spindle whorl so as to realize the function of driving the doffer to travel, so that exact positioned traveling of the doffer is realized and slippage phenomenon is avoided. Because the dialing block is stretching, the interference between the dialing block and the spindle whorl in the transmission piece movement process is avoided; and because the center lines of the spindle whorl and spindles are consistent, the traveling accuracy is guaranteed. Due to use of the device, the upper and lower rails of the traditional ring spinner are not needed to be changed; and the device is simple and reliable in structure, and low in manufacture and maintenance cost, and is suitable for intermittent moving type or continuous moving type automatic doffers.

Description

technical field [0001] The invention belongs to the technical field of ring spinning doffing equipment, and in particular relates to a structural design of a walking device of an automatic ring spinning doffing machine. Background technique [0002] Ring spinning is a very important and common spinning technology. The spun yarn production process needs to remove the spun bobbins, which is called doffing. [0003] At present, the existing double-disc automatic doffing machine adopts the front guide wheel and the rear guide wheel to contact the upper track of the ring spinning machine, uses the auxiliary wheel to contact the lower track of the ring spinning machine, and drives the rear guide wheel to rotate after deceleration by the motor , so as to drive the doffer to advance along the upper track of the ring spinning machine. Because when walking, it mainly advances through the friction between the rear guide wheel and the upper track, and slipping occurs during walking, an...
