Abstract
The utility model discloses a driving mechanism of a machine head presser foot of an embroidery machine. The driving mechanism comprises a housing and a drive shaft mounted on the housing, wherein a presser foot slide is mounted on the drive shaft; a stepping motor is mounted on the housing; the presser foot slide is connected with a connecting rod component; the stepping motor drives the connecting rod component via an intermediate transmission component; and the individual stepping motor in a machine head of each embroidery machine drives the presser foot slide to operate via the intermediate transmission component and the connecting rod component.According to the driving mechanism, the stepping motor is adopted to independently drive the independent lifting presser foot, impact of the presser foot pressing cloth is greatly reduced, the noise and machine head vibration are reduced, and cloth pressing height of the presser foot can be adjusted freely according to a pattern, so that the quality and exquisiteness of an embroidery are improved.
Description
Technical field
The utility model relates to machine head of embroidery machine, relates in particular to presser feet driving mechanism.
Background technology
As shown in Figure 1, the presser feet driving mechanism of machine head of embroidery machine in prior art, the presser feet being driven in each head by the rotary main shaft 12 through a plurality of head casings 1, its motion principle is that pressure foot lifting cam 13 is fixed on rotary main shaft, rotation by rotary main shaft makes pressure foot lifting cam 13 drive presser feet connecting rod 14, and presser feet connecting rod 14 drives presser feet slide 11 that presser feet slide 11 is moved back and forth on driving shaft by connecting connecting rod 20 again.
From structure, this structure has the following disadvantages:
1. while installing, pressure foot lifting back of cam does not have corresponding benchmark, only with screw, presser feet cam mount pad is held tightly, and this kind of installation easily makes pressure foot lifting cam produce distortion.
2. because of cam curve track, fix, so the reciprocating stroke of presser feet driven unit motion will be changeless, the height of presser feet compress will be also changeless thus, and height during different embroidery presser feet compress has a different value, the embroidery of working it out above numerical value at this will be more exquisite, and quality will be better.
3. this structure running needs rotary main shaft to drive this will increase the load of rotary main shaft.
Utility model content
Many deficiencies that the utility model exists for presser feet driving mechanism in prior art, provide a kind of machine head of embroidery machine presser feet driving mechanism, easier for installation, turn round more stable, fundamentally promote quality and the exquisite degree of embroidery,
For solving the problems of the technologies described above, the utility model adopts following technical scheme: machine head of embroidery machine presser feet driving mechanism, comprise casing and be installed on the driving shaft on casing, presser feet slide is installed on driving shaft, one stepper motor is installed on described casing, described presser feet slide is connected with link assembly, and between stepper motor and link assembly, by the transmission of intermediate transmission assembly, a stepper motor independent in each machine head of embroidery machine drives presser feet slide to move by intermediate transmission assembly and link assembly.
Preferably, described intermediate transmission assembly comprise driving pulley, driven pulley and be located at driving pulley and driven pulley on belt, driving pulley is installed on the output shaft of stepper motor, driven pulley is installed on a belt wheel transmission axle.
Preferably, described link assembly comprises that a lifting connecting rod is connected connecting rod with one, and the head end that promotes connecting rod is articulated with on belt wheel transmission axle, and the tail end that promotes connecting rod is hinged with the head end that is connected connecting rod, and the tail end and the presser feet slide that connect connecting rod are hinged.
Preferably, described intermediate transmission assembly comprises intermeshing driving gear and driven gear, and driving gear is installed on the output shaft of stepper motor, and driven gear is installed on a gearing shaft, and gearing shaft is connected with link assembly.
The utility model arranges separately a stepper motor and drives presser feet on each head casing, stepper motor is by a constant-speed ratio, by the driving pulley being arranged on stepper motor output shaft, drive driven pulley, driven pulley drives belt wheel transmission axle and promotes connecting rod, then connects connecting rod and drives the independent lift presser feet on presser feet slide to pump on driving shaft.
From structure, this structure has the following advantages:
1. can adopt the stepper motor in each head of software control, stepper motor drive presser feet slide and presser feet, drive without unified rotary main shaft.
2. adopt the independent driving of stepper motor independently to promote presser feet, greatly alleviate the impact of presser feet compress, reduce noise, reduce head vibration.
3. owing to adopting software to control separately stepper motor and the corresponding presser feet single movement in each head, the height of presser feet compress can be adjusted arbitrarily according to style, thereby improves embroidery quality and exquisite degree.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Fig. 1 is the structural representation of machine head of embroidery machine presser feet driving mechanism in prior art;
Fig. 2 is the structural representation of the utility model machine head of embroidery machine presser feet driving mechanism.
The specific embodiment
As shown in Figure 2, machine head of embroidery machine presser feet driving mechanism of the present utility model, comprises casing 1 and is installed on the driving shaft 10 on casing 1, and presser feet slide 11 is installed on driving shaft 10, one stepper motor 4 is installed on described casing 1, and stepper motor 4 is installed on casing 1 by motor mounting plate 40.Described presser feet slide 11 is connected with link assembly, between stepper motor 4 and link assembly, by the transmission of intermediate transmission assembly, a stepper motor 4 independent in each machine head of embroidery machine drives independently presser feet slide 11 actions by intermediate transmission assembly and link assembly.
Described intermediate transmission assembly comprise driving pulley 30, driven pulley 31 and be located at driving pulley and driven pulley on belt 3, driving pulley 30 is installed on the output shaft of stepper motor 4, driven pulley 31 is installed on a belt wheel transmission axle 32.Belt wheel transmission axle 32 is supported on rolling bearing 33, and rolling bearing 33 is installed on bearing mounting base 34.By bel-drivenn advantage, be stable drive, greatly alleviate the impact of presser feet compress, reduce noise, reduce head vibration.Described link assembly comprises that a lifting connecting rod 2 is connected connecting rod 20 with one, and the head end that promotes connecting rod 2 is articulated with on belt wheel transmission axle 32, and the tail end that promotes connecting rod 2 is hinged with the head end that is connected connecting rod 20, and the tail end and the presser feet slide 11 that connect connecting rod 20 are hinged.
Motion principle of the present utility model is: stepper motor 4 is by a constant-speed ratio, by the driving pulley 30 being arranged on stepper motor output shaft, drive driven pulley 31, driven pulley 31 drives belt wheel transmission axle 32 and promotes connecting rod 2, then connecting connecting rod 20 drives presser feet slide 11 to pump along driving shaft, meanwhile, the independent lift presser feet being connected with presser feet slide 11 pumps.
