Example Embodiment

[0034] Example 1: Control figure 1 Attach figure 2 A staple buckle motor drives the raised pressure cutting mechanism, the output shaft of the motor 1 is connected to the carrier assembly, and the carrier pad drive rod 2 is hinged at a fixed rotation axis. On one end of the screw 3, one end of the raised shear driving rod 2 is connected to the carrier assembly, and the other end is connected to the two-way motor, and the motor shaft is driven by two-way rotation. The rotating axial screw 3 rotates in different directions and drives the raised pressure cutting operation and the reset action.

[0035] Contrast Figure 7 Attach Figure 8 The raised shear drive rod 2 is a counter Z-shaped rod, and the connection structure of the other components is that the transmission assembly and the shear assembly are hinged to the lower end of the raised pad drive rod 2 and passed the same axis. The screw hinges; the rotating axis screw 3 is located at the upper end of the raised pressure cutting r...

Example Embodiment

[0043] Example 2: Control image 3 Attach Figure 4 The present invention also provides another transmission assembly including: the active gear 17 fixed to the motor shaft, the active gear 17 and the driven gear 18 fixed to the transmission shaft 14, the drive shaft 14 A transmission crank 19 is also fixed, and the transmission crank 19 is hinged to one end of the transmission link 16, and the other end of the transmission link 16 is hinged to the carrier pad drive rod 2. Other components in Example 2 Such as the raised pressure shear driving rod 2, the pressing assembly, and the shear assembly are the same as in the first embodiment.

[0044] The active gear 17 is fixed to the end of the motor shaft, and the driven gear 18 is fixed to the end of the transmission shaft 14, and the drive crank 19 is a gap between the driven gear 18.

[0045] The diameter of the driven gear 18 is larger than the active gear 17, the puller ratio of the driven gear 18 and the active gear 17 is greater ...

Abstract

The invention belongs to the technical field of button attaching machines, and relates to a motor-driven lifting and pressing and thread trimming mechanism for a button attaching machine. An output shaft of a motor is connected with a lifting and pressing and thread trimming driving rod through a transmission assembly, the lifting and pressing and thread trimming driving rod is hinged to a fixed rotating shoulder screw, one end of the lifting and pressing and thread trimming driving rod is connected with a lifting and pressing assembly, and the other end of the lifting and pressing and threadtrimming driving rod is connected with a thread trimming assembly; and the motor is a two-way motor, when a motor shaft rotates in two directions, the motor shaft drives the lifting and pressing and thread trimming driving rod to rotate in different directions around the rotating shoulder screw correspondingly and a lifting and pressing and thread trimming action and a reset action are driven respectively. According to the motor-driven lifting and pressing and thread trimming mechanism for the button attaching machine, impact on related connecting pieces is reduced, noise is lowered, and the service life of products is prolonged.

Description

technical field [0001] The invention belongs to the technical field of button sewing machines, and relates to a button sewing machine motor-driven lifting pressure cutting thread mechanism. Background technique [0002] At present, most chain-type button sewing machines use electromagnets to drive the link mechanism to drive the lifting and thread cutting mechanisms. For example: [0003] Chinese invention patent application CN106988032A discloses an automatic presser foot lifting mechanism and a button sewing machine, which includes a driving member, a connecting rod connected to the driving member for linear reciprocating motion, and a presser foot lifting rod, which is rotated and positioned , one end of the presser foot lifting rod is slidably connected to the end of the connecting rod through a sliding assembly, and the sliding direction of the sliding assembly forms an included angle with the moving direction of the connecting rod, and the other end of the presser foo...
