Background technology:
In the automation sewing-machine equipment, middle presser bar lifting mechanisms uses air cylinder lifting, only has the highest, minimum two-stage stroke, can't realize intelligent digital control, use presser feet control in the two-part, can't carry out according to the actual height of making object and follow the tracks of programming, regulate inconvenient, the product of making out is not attractive in appearance, has dwindled adaptability and the scope of application of Sewing machines to sewings; And the impact noise that produces when having the cylinder block row to be at the end with cylinder control.
The utility model content:
The purpose of this utility model is for the deficiencies in the prior art, and provide presser bar lifting mechanisms in a kind of Sewing machines, the simple science of its structural design, realize intelligent digital control, can carry out according to the actual height of making object and follow the tracks of programming, easy to adjust, the product of making out is attractive in appearance, and Sewing machines enlarges adaptability and the scope of application of sewings.
For achieving the above object, the utility model adopts following technical scheme, it comprises the computer programming control circuit, the stepper motor circuit module, stepper motor, eccentric cam, a L-type lever sheet, thick stick spare is connected, No. two L-type lever sheets, middle presser feet push rod, whippletree, computer programming control circuit control step motor circuit module, stepper motor circuit module control step motor, the output shaft of control step motor is connected with eccentric cam, eccentric cam and a L-type lever sheet are in mating connection, No. one L-type lever sheet is connected with an end of the thick stick spare that is connected, the other end of thick stick spare of being connected is connected with No. two L-type lever sheets, the corner of No. two L-type lever sheets props up the top of middle presser feet push rod, and middle presser feet push rod and whippletree are hinged.
Described middle presser feet push rod and whippletree activity are hinged.
Described eccentric cam, L-type lever sheet, the thick stick spare that is connected, No. two L-type lever sheets, middle presser feet push rod, whippletrees interaction structure that mutually constitutes by an active connection.
The utility model beneficial effect is: computer programming control circuit control step motor circuit module, stepper motor circuit module control step motor, the output shaft of control step motor is connected with eccentric cam, eccentric cam and a L-type lever sheet are in mating connection, No. one L-type lever sheet is connected with an end of the thick stick spare that is connected, the other end of thick stick spare of being connected is connected with No. two L-type lever sheets, the corner of No. two L-type lever sheets props up the top of middle presser feet push rod, middle presser feet push rod and whippletree are hinged, the simple science of its structural design, realize intelligent digital control, can carry out according to the actual height of making object and follow the tracks of programming, easy to adjust, the product of making out is attractive in appearance, and Sewing machines enlarges adaptability and the scope of application of sewings.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
The specific embodiment:
As shown in Figure 1: the utility model comprises computer programming control circuit 1, stepper motor circuit module 2, stepper motor 3, eccentric cam 4, a L-type lever sheet 5, thick stick spare 6 is connected, No. two L-type lever sheets 8, middle presser feet push rod 9, whippletree 10, computer programming control circuit 1 control step motor circuit module 2, stepper motor circuit module 2 control step motors 3, the output shaft 31 of control step motor 3 is connected with eccentric cam 4, eccentric cam 4 and a L-type lever sheet 5 are in mating connection, No. one L-type lever sheet 5 is connected with an end of the thick stick spare 6 that is connected, the other end of thick stick spare 6 of being connected is connected with No. two L-type lever sheets 8, the corner of No. two L-type lever sheets 8 props up the top of middle presser feet push rod 9, and middle presser feet push rod 9 is hinged with whippletree 10.
Described middle presser feet push rod 9 is hinged with whippletree 10 activities.
Described eccentric cam 4, L-type lever sheet 5, the thick stick spare 6 that is connected, No. two L-type lever sheets 8, middle presser feet push rod 9, whippletrees 10 interaction structure that mutually constitutes by an active connection.
With stepper motor 3 as power source, utilize the eccentric cam 4 that designs the eccentric wheel footpath through accurate Calculation, by changing the corner of stepper motor 3, the corner of a L-type lever sheet 5 that leans against on eccentric cam 4 outer rims is changed, and after C ratio speed change through the corner generation respective change of 8, No. two L-type levers of thick stick spare 6 No. two L-type lever sheets of the pulling sheet 8 that is connected, presser feet push rod 9 is done up and down in the drive, thereby make the whippletree 10 whippletree respective activity of connection, the noise that can not produce.
The above only is preferred embodiment of the present utility model, therefore all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
