TECHNICAL FIELD

Each group of rope embroidery components includes an independent motor to drive the corresponding group of rope swing and loop punching head. The loop punching head and the driving motor are transmitted through a synchronous belt wheel assembly. With the increase of the number of loop punching heads, in order to maintain the transmission path without affecting the use of other functional mechanisms, the synchronous belt drive needs to be provided with a steering wheel and a tension wheel. The more the number of loop punching heads, the more complex the transmission. The multi-color rope embroidery of this structure can usually be set to three groups, and can be set to four groups at most.

[0004] The rope feeder (rope feeding mechanism) of each group of rope embroidery components is provided with an independent driving motor, which results in a large volume of the rope feeder, which is not convenient for compact arrangement and layout of three or more groups. According to the existing embroidery machine structure, the number of groups of the rope feeder is not more than three, otherwise the reasonable layout of the entire device needs to be greatly sacrificed.

[0056] Referring to Figures 1-16In the invention, the front in the orientation words is the direction in which the feeding mechanism 6 drives the corresponding rope embroidery mechanism 1 to advance towards the embroidery needle, and vice versa, the direction in which the feeding mechanism 6 drives the corresponding rope embroidery mechanism 1 to retreat away from the embroidery needle is the rear.

[0057] A multi-rope embroidery device, comprising a rope embroidery assembly 10 provided with at least two groups of rope embroidery mechanisms 1, a base frame 8, a transmission assembly 7, a driving assembly 4, a sliding switching mechanism 5, a feeding mechanism 6, and a rope feeding assembly 20. Each group of rope embroidery mechanisms 1 comprises a support 11, a looping head 12 arranged on the support 11, and a tension controller 13. The rope feeding assembly 20 comprises a plurality of rope feeders 2 corresponding to the number of groups of rope embroidery mechanisms 1,

[0058] The base frame 8 is used to position and install various components, and the specific shape of the base frame 8 can be determined according to the compact installation of various components. The base frame 8 is provided with mounting sites or mounting structures necessary for connecting various components, and the base frame 8 can comprise a plurality of base frames connected to different functional components. The base frame 8 can also be connected to a lifting mechanism 9 for lifting the entire device. The lifting mechanism 9 generally comprises a connecting frame connected to the base frame 8 through a guide rail assembly, and the connecting frame can be connected to the corresponding part of the embroidery machine body or head. A cylinder is provided between the connecting frame and the base frame 8 to drive the lifting of the base frame 8.

[0059] The transmission assembly 7 is arranged on each group of rope embroidery mechanisms 1 and is used to drive the looping head 12. The transmission assembly 7 comprises a transmission shaft 71, and a transmission structure is provided between the transmission shaft 71 and the looping head 12 to drive the looping head 12. The transmission structure is generally a transmission belt wheel and a transmission belt arranged between the looping head 12 and the transmission shaft 3, and is preferably a synchronous belt. Of course, other existing convenient implementation schemes can also be used instead.

[0060] The driving assembly 4 is used to drive the looping head 12 of the cord knitting mechanism 1 into the working position. The driving assembly 4 comprises a first driving motor 41 mounted on the base frame 8, a driving shaft 42 connected with the first driving motor 41, and a meshing block structure arranged between the driving shaft 42 and the transmission shaft 71 for mutual transmission. In the present application, the meshing block structure can adopt the structure of the prior art. Specifically, the meshing block structure can satisfy the transmission between the transmission shaft 71 and the driving shaft 42 when the cord knitting mechanism 1 slides forward with the feeding mechanism 6, and the transmission between the transmission shaft 71 and the driving shaft 42 is disconnected when the cord knitting mechanism 1 slides backward with the feeding mechanism 6. For example, the meshing block structure can be two semicircular convex blocks which form a complete circle. Specifically, a first semicircular convex block is arranged on the driving shaft 42 and extends downward along the axial direction, and a second semicircular convex block is arranged on the transmission shaft 71 and extends upward along the axial direction. The first semicircular convex block and the second semicircular convex block can form a complete cylinder through sliding. When the cord knitting mechanism 1 slides to the working position with the feeding mechanism 6, the first semicircular convex block and the second semicircular convex block are connected to realize transmission. When the cord knitting mechanism 1 slides backward with the feeding mechanism 6, the first semicircular convex block and the second semicircular convex block are completely disconnected.

[0061] In order to arrange the components compactly, the driving assembly 4 further comprises a second pulley transmission assembly 43 connected between the driving shaft 42 and the shaft of the first driving motor 41. The meshing block structure comprises at least one first convex block 44 arranged on the corresponding end of the driving shaft 42 and at least one second convex block 45 arranged on the transmission shaft 71 and matched with the first convex block 44. The first convex block 44 and the second convex block 45 are arranged in a matched manner. The positioning structure 53 arranged on each cord knitting mechanism 1 comprises a positioning block 58 matched with the second convex block 45 on the transmission shaft 71 to position the transmission shaft 71. The first convex block 44 or the second convex block 45 is arranged in a matched manner to form a clamping groove for accommodating the opposite convex block. In the present embodiment, the first convex block 44 is arranged in the middle of the driving shaft 42, and the second convex block 45 is arranged in a symmetrical manner on the corresponding end of the transmission shaft 71. The recess groove between the two second convex blocks 45 forms a clamping groove matched with the first convex block 42. The clamping groove can also be matched with the positioning structure 53 to position the initial position of the transmission shaft 42, so that the cord knitting mechanism 1 can be quickly and smoothly matched with the first convex block 44 on the driving shaft when the cord knitting mechanism 1 is fed into the working position.

[0062] The sliding switching mechanism 5 is used to drive the rope embroidery assembly 10 to slide relative to the base frame 8 so as to switch the corresponding rope embroidery mechanism 1 to slide to the rope feeding position. The sliding switching mechanism 5 includes a second driving structure 51 installed on the base frame 8 to drive the rope embroidery mechanism 1 and a sliding seat 52 that can be slidably disposed on the base frame 8.

[0063] The feeding mechanism 6 is used to drive the corresponding embroidery mechanism 1, which has entered the rope feeding position, to slide forward and enter the working position to cooperate with the needle. The sliding causes the engagement block structure between the transmission shaft 71 and the drive shaft 42 of the corresponding embroidery mechanism 1 to engage and transmit power. The feeding mechanism 6 is also used to drive the corresponding embroidery mechanism 1, which has entered the rope feeding position, to slide backward and exit the working position. The sliding causes the engagement block structure between the transmission shaft 71 and the drive shaft 42 of the corresponding embroidery mechanism 1 to disengage and release the transmission. The feeding mechanism 6 includes a third drive structure 61 mounted on the base frame 8 to drive the corresponding embroidery mechanism 1, which has entered the rope feeding position, to slide backward.

[0064] To facilitate rapid engagement between the transmission shaft 71 and the drive shaft 42, the sliding seat 52 is equipped with a positioning structure 53 for positioning the transmission shaft 71 of each group of embroidery mechanisms 1. When each group of embroidery mechanisms 1 is disengaged from the working position, the transmission shaft 71 engages with the positioning structure 53. By positioning the transmission shaft 71 disengaged from the working position through the positioning structure 53, the corresponding block of the engagement block structure on the transmission shaft 71, namely the second protrusion 44, remains engaged with the first protrusion 42. This allows for quick and direct driving of the embroidery mechanism 1 into the working position via the feeding mechanism during the next use, enabling rapid engagement between the transmission shaft 71 and the engagement block structure on the drive shaft 42, namely the first and second cams.
