Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a lifting and cycloiding device of a bobbin core and bobbin case unwinding machine. Background Art

[0002] Currently, during the winding process, the automatic bobbin case thread changing equipment needs to drive the wire to rise and fall, and rotate with the bobbin case so that the wire is wound into the winding groove of the bobbin case. Therefore, the lifting height of the wire needs to be controlled with high precision.

[0003] The applicant's prior research and development achievements: Chinese patent CN117947584A discloses a shearing and breaking device for a fully automatic winding and thread-removing platform for bobbins and bobbins of textile machines. The device comprises an inlet thread end positioning unit, a shearing unit, and an outlet thread end positioning unit, which are arranged on the fully automatic winding and thread-removing platform in sequence from the inlet end to the outlet end. The inlet thread end positioning unit positions and clamps the thread end at the inlet end after the thread is cut. The shearing unit cuts the thread between the inlet thread end positioning unit and the outlet thread end positioning unit. The outlet thread end positioning unit is raised and lowered to position the thread end at the outlet end after the thread is cut. This shearing and breaking device can clamp and position the cut thread ends, making it easier for the robot arm of the fully automatic winding and thread-removing platform to grasp the broken thread ends. It has a simple structure and is easy to implement.

[0004] Based on the structure of the above-mentioned shearing and wire-cutting device, the applicant discovered the following problems with the mechanism responsible for driving the wire to rise and fall: the motor drives the swing arm to control the rise and fall of the slider, so as to drive the clamping claws on the slider to rise and fall. This labor-intensive lever structure causes the motor output force arm to be extremely small, and the longer the swing arm, the larger the load force arm, which greatly loads the motor, reduces the service life of the motor, and is prone to problems such as motor loss of rotation.

[0005] Therefore, how to design a cycloid device to solve the problem of motor output and increase the service life of the motor has become a technical problem that needs to be solved urgently by people in this field. Utility Model Content
