Description
Technical Field
The utility model relates to a presser foot mechanism in sewing machine's electron.
Background
The middle presser foot is an indispensable mechanism of the special sewing machine and is a necessary condition for ensuring stitch formation. The traditional middle presser foot mechanism is related to a main shaft, and the middle presser foot moves up and down by the driving of a main shaft motor. The structure is relatively complex, the number of components is large, the synchronization of the presser feet is troublesome to adjust, and the adjusting range is limited.
The traditional middle presser foot action is limited by the movement of the main shaft, namely the main shaft can drive the middle presser foot mechanism to move together by rotating; in addition, the conventional mechanical type adjustment of the movement time of the middle presser foot is to adjust the synchronization time with the main shaft through the eccentric amount of an eccentric cam on an adjusting mechanism, and the eccentric amount is limited and cannot be adjusted to a certain angle.
Disclosure of Invention
The utility model aims at solving the technical problems of troublesome synchronous adjustment and limited adjusting range of the middle presser foot structure associated with the main shaft.
For the purpose of the utility model discloses above the realization, the utility model provides a presser foot mechanism in sewing machine's electron, include aircraft nose, motor, first gear, second gear, lift the last, lift the pressure crank, lift pressure connecting rod and presser bar of pressure, the motor install in the side of aircraft nose, install on the transmission shaft of motor first gear, first gear with lift the epaxial second gear meshing of pressing, lift and still install simultaneously on the pressure axle lift the pressure crank, lift the pressure crank pass through axle position screw with lift the one end of pressing the connecting rod and connect, lift and press the connecting rod other end and be connected with the depression bar slider, the presser bar is worn to locate in the depression bar slider and fixed.
Further, the motor is vertically installed at a side surface of the head.
Further, the first gear is mounted on the transmission shaft, the second gear is mounted on the pressure lifting shaft, and the first gear and the second gear are perpendicular to each other and meshed with each other.
Further, the lift shaft is installed through inner shaft holes of the first bearing set and the second bearing set on the machine shell.
Compared with the prior art, the beneficial effects of the utility model are that:
the motor of the utility model is externally arranged on the casing, and the installation and maintenance are more convenient; in addition, the precision of the transmission through the gear is higher, the structure is simpler and more flexible, and the cost is not high.

Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
fig. 2 is a state diagram of an embodiment of the present invention;
fig. 3 is an exploded view of an embodiment of the present invention.
In the figure, a handpiece 1; a motor 2; a transmission shaft 21; a first gear 3; a second gear 4; lifting and pressing the shaft 5; a first bearing set 6; a second bearing set 7; the crank 8 is lifted and pressed; the connecting rod 9 is lifted and pressed; a shaft position screw 10; a press rod slider 11; a presser bar 12; presser bar sleeve 13.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-3, an embodiment of the electronic middle presser foot mechanism of the sewing machine of the present invention includes a head 1, a motor 2, a first gear 3, a second gear 4, a pressure lifting shaft 5, a pressure lifting crank 8, a pressure lifting connecting rod 9, and a presser foot rod 12. The motor 2 is fixedly arranged on the side surface of the machine head 1 through a screw, and a transmission shaft 21 of the motor is provided with a first gear 3; the pressure lifting shaft 5 sequentially penetrates through a first bearing group 6 and a second bearing group 7 which are installed on the machine shell, one end of the pressure lifting shaft 5 is provided with a second gear 4, the second gear 4 is meshed with the first gear 3, the other end of the pressure lifting shaft 5 is provided with a pressure lifting crank 8, the pressure lifting crank 8 is connected with one end of a pressure lifting connecting rod 9 through a shaft position screw 10, and the other end of the pressure lifting connecting rod 9 is connected with a pressure rod sliding block 11 through a shaft position screw 10. When the motor 2 rotates in a reciprocating manner, the lifting and pressing shaft 5 is driven to do reciprocating movement, the lifting and pressing crank 8 is driven to swing by taking the axis of the lifting and pressing shaft 5 as a fulcrum, the lifting and pressing connecting rod 9 is driven to do up-and-down movement, the pressing rod sliding block 11 and the pressing foot rod 12 are driven to do up-and-down movement at the same time, and the pressing foot rod shaft sleeve 13 is used as a guide part for the pressing foot rod 11 to do up-and-down movement.
The traditional middle presser foot action is limited by the movement of the main shaft, namely the main shaft rotates to drive the middle presser foot mechanism to move together. In the embodiment of the utility model, the motor is used for independent driving, so that the situation can not occur, and the presser foot mechanism can be fixed during the rotation of the main shaft.
In addition, the conventional mechanical type adjustment of the movement time of the middle presser foot is to adjust the synchronization time with the main shaft through the eccentric amount of an eccentric cam on an adjusting mechanism, and the eccentric amount is limited and cannot be adjusted to a certain angle. The embodiment of the utility model provides an in, the motor independent control is convenient simple, as long as just can through the parameter that sets up on automatically controlled, need not remove adjustment machinery, and adjustable range is bigger moreover.
The control software involved in the utility model adopts the prior art.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
