Description

Technical Field

[0001] The utility model relates to the technical field of rollers, in particular to a motor-driven roller with synchronous rotation speed. Background Art

[0002] Roller refers to the rolling long or short axis that presses the yarn or fiber. It is a cylindrical rotating part in textile machinery that plays the role of feeding, drafting, and output.

[0003] The existing electric roller motor drive shaft and roller roller are respectively fixed on the inner ring and outer ring of the bearing, and the rotation speed of the drive shaft and roller cannot be consistent. The existing electric roller adopts an extended motor main shaft, and the main shaft and the rotor are processed as a whole. The inner ring of the bearing is installed on the main shaft, and the roller roller is installed on the outer ring of the bearing. The main shaft is too long, and the front end is a cantilever shaft, which is prone to active jumping, causing the outer circle of the roller roller to jump; the main shaft jump causes the bearing to heat up and get stuck, affecting the service life of the bearing and the entire roller. The motor main shaft and roller roller are respectively fixed on the inner ring and outer ring of the bearing, and the motor cannot control the rotation speed of the roller roller. Therefore, the utility model provides a motor-driven roller with synchronized rotation speed to solve the above-mentioned problems. Utility Model Content

The rotating rod passes through the slider, and the slider is threadedly connected to the rotating rod, and two opposite thread lines are provided on the rotating rod corresponding to the two sliders. The rotating rod is driven to rotate by rotating the rotating handle, and the rotating rod drives the two sliders and the limit rings to move closer to or away from each other, thereby facilitating the adjustment of the distance between the two limit rings.

[0010] As a further solution of the utility model, the slider is connected to a limit rod in a front-to-back symmetrical sliding manner, and the left and right sections of the limit rod are fixedly connected to the inner wall of the slide groove. The rotating rod is symmetrically provided with stop blocks corresponding to the slider on the left and right sides.

[0013] 2. When the utility model is used, the motor does not have an extended main shaft, and the roller cylinder is fixedly connected through the roller transmission shaft head, the motor connecting seat and the bearing, which prevents the roller from jumping and bearing damage caused by the lengthening of the main shaft, and improves the working transmission accuracy and service life of the roller.

[0014] 3.
