Description

Technical Field

[0001] This utility model belongs to the field of button attaching machine technology, and specifically refers to a button attaching machine with a geared motor. Background Technology

[0002] The basic operation of a button-attaching machine is driven by a motor, which in turn drives the punch rod on the motor base to move up and down. Button-attaching machines are frequently used in the garment industry. Their small size and ease of operation make them widely popular. Most button-attaching machines on the market use ordinary motors or servo motors to drive the button-pressing shaft. Typically, the button-pressing shaft performs one downward operation once the motor rotates one revolution. Currently, the motors on button-attaching machines are traditional motors, whose main components are a metal housing and plastic end caps. The stator is located inside the metal housing, and the rotor passes through the stator. The rotor is connected to the button-pressing shaft through an eccentric wheel assembly. The aforementioned motors are relatively large and have low power. Utility Model Content
