Description

Technical Field

[0001] The utility model relates to the technical field of rope embroidery, in particular to a rope embroidery driving mechanism. Background Art

[0002] The existing cord embroidery device includes a needle bar frame, an embroidery frame arranged at the lower end of the needle bar frame, a cord feeding mechanism, etc., wherein the inlay sleeve of the cord feeding mechanism is generally arranged directly below the corresponding needle bar, and the needle bar needs to pass through the inlay sleeve for needle embroidery. Since the inlay sleeve is generally arranged directly below the needle bar, it is usually close to the embroidery cloth on the embroidery frame.

[0003] In order to cooperate with the needle bar and adapt to the narrow space between the embroidery machine head and the rope embroidery device, the insert sleeve and the driving motor that drives the insert sleeve to rotate must be transmitted through a transmission mechanism. The transmission mechanism includes a transmission shaft coaxially connected to the driving motor. The bottom of the transmission shaft is connected to the driving shaft of the insert sleeve through a synchronous pulley structure. Generally, a synchronous pulley structure is adopted. Affected by the existing size of the driving motor and the fact that it is installed on the outside of the mounting frame, the existing synchronous belt is set relatively long. The driving shaft and the synchronous pulley structure occupy the space at the bottom of the mounting frame, which will squeeze the range of movement of the embroidery frame.

[0004] In order to facilitate rope transmission, the synchronous belt assembly is close to the embroidery frame and the embroidery cloth. When the embroidery frame moves the embroidery cloth, the edge of the embroidery frame will hit the transmission assembly or transmission shaft of the inlaid sleeve, which limits the range of movement of the embroidery frame and reduces the range of rope embroidery.

[0005] There is also a sleeve drive mechanism. In addition to the driving wheel and the driven wheel, the synchronous pulley assembly is also provided with a tensioning wheel and a steering pulley to adjust the shape of the synchronous belt. The structure is complex, and only one synchronous belt is provided, and it rubs with multiple pulleys, resulting in large losses and shortening the service life of the synchronous belt. Summary of the invention

[0006] In order to solve the problems of the above-mentioned prior art, the utility model provides a rope embroidery drive mechanism, which adopts a transmission shaft and sets a two-stage transmission, thereby reducing the volume occupied by the transmission component of the inlaid sleeve close to the embroidery frame. The embroidery frame is not easy to hit the transmission component when moving, and the movable range of the embroidery frame is increased.

[0007] The technical solutions adopted are as follows:

[0008] A cord embroidery drive mechanism comprises a drive motor, a sleeve, a drive shaft for driving the sleeve to rotate, and a mounting frame, wherein the drive shaft is provided with a connecting hole matched with the sleeve, and further comprises a transmission shaft installed on the mounting frame, close to a matching needle bar frame or / and one side of the drive shaft, a first synchronous belt assembly is provided between the drive shaft and the transmission shaft, and a second transmission belt assembly is provided between the drive motor and the transmission shaft.

[0009] Furthermore, the mounting frame is extended with an extension seat.

[0010] Furthermore, an angle is formed between the length direction of the extension seat and the axis direction of the driving pulley and the passive pulley of the second synchronous belt assembly, and the extension seat is tilted toward one side of the matching needle bar frame.

[0011] Furthermore, the first synchronous belt assembly includes a first synchronous belt pulley arranged on the driving shaft, a second synchronous belt pulley arranged at the lower end of the transmission shaft, and a first synchronous belt arranged between the first and second synchronous belt pulleys.

[0012] Furthermore, the second synchronous belt assembly includes a third synchronous belt pulley arranged at the upper end of the transmission shaft, a fourth synchronous belt pulley arranged at the motor output shaft, and a second synchronous belt arranged between the third and fourth synchronous belt pulleys.

[0013] Furthermore, the mounting frame may be a mounting frame for mounting a tensioning rocker arm structure, a mounting frame used solely for mounting a transmission shaft, or a motor mounting frame.

[0014] Furthermore, the driving shaft is provided with a bearing outside, the bearing is provided with a bearing seat outside, and the bearing seat is arranged on the extension seat.

[0015] Furthermore, the inlay sleeve and the driving shaft can be integrally arranged to form a rope embroidery structure.

[0016] Compared with the prior art, the beneficial effects produced by the utility model are:

[0017] The utility model provides a cord embroidery driving mechanism, comprising an insert sleeve, an insert sleeve driving shaft and a driving motor, and also comprising a transmission shaft arranged on a mounting frame, wherein the transmission shaft is installed close to a matching needle bar frame or / and one side of the driving shaft and is relatively close to the insert sleeve, a first synchronous belt assembly is arranged between the driving motor and the transmission shaft, and a second synchronous belt assembly is arranged between the transmission shaft and the driving shaft of the insert sleeve, and a two-stage transmission is adopted, thereby reducing the loss of the transmission belt and increasing the service life of the transmission belt.

[0018] Compared with the prior art in which a transmission assembly is directly arranged between the insert sleeve driving shaft and the motor shaft of the driving motor, the utility model adopts a two-stage transmission in the transmission shaft, and the installation method of the first and second synchronous belt assemblies can be adjusted, and the space at the bottom of the mounting frame can be vacated, which meets the installation requirements of the small head distance between the existing machine heads, and the space occupied by the second synchronous belt assembly that drives the insert sleeve to rotate is relatively small. The driving mechanism of the utility model can vacate the space at the bottom of the mounting frame and has a higher spatial height from the embroidery frame frame. The embroidery frame has a larger effective range of activity and is not easy to hit the second synchronous belt assembly. BRIEF DESCRIPTION OF THE DRAWINGS
