The looping head and the driving motor are driven by a synchronous belt pulley assembly. As the number of looping heads increases, in order to keep the transmission path from 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 looping heads there are, the more complex the transmission becomes. The multi-color cord embroidery of this structure can usually only be provided with three groups, and the upper limit is barely set to four groups.

[0004] The rope feeder (rope retracting and releasing mechanism) of each rope embroidery component is equipped with an independent driving motor, which makes the rope feeder larger in size and inconvenient for compactly arranging more than three groups.

The lifting mechanism 81 generally includes a cylinder that can be connected and installed at the external support part and necessary guide rail components.

[0035] The first driving structure 4 is used to drive the looping head 12 of the cord embroidery mechanism 1 into the working position. The first driving structure 4 includes a bracket 41, a third driving motor 42 installed on the bracket 41, and a driving shaft 43 connected to the third driving motor 42. The third driving motor 42 can be installed at the corresponding position of the bracket 41. The bracket 41 is slidably connected to the base frame 8. In this embodiment, a second pulley transmission assembly 44 is also provided between the third driving motor 42 and the driving shaft 43.

The second pulley transmission assembly 44 is preferably a synchronous pulley assembly, which usually includes a second passive pulley installed on the driving shaft 43, a second active pulley installed on the third driving motor 42, and a second transmission belt.

[0036] The first sliding driving structure 5 is usually arranged between the base frame 8 and the cord embroidery assembly 10 as needed, and is used to drive the cord embroidery assembly 10 to slide relative to the base frame 8 so as to drive the corresponding cord embroidery mechanism 1 to slide to the working position.

[0037] The second sliding driving structure 6 is used to drive the first driving structure 4 to slide, so that the first driving structure 4 can enter the driving position, so that the driving shaft 43 of the first driving structure 4 matches with the transmission shaft 3 of the corresponding cording mechanism entering the working position, or the first driving structure 4 can be separated from the driving position, so that the driving shaft 43 of the first driving structure 4 is separated from the transmission shaft 3. The second sliding driving structure 6 is usually a lifting structure that drives the first driving structure 4 to rise and fall.

[0038] The second transmission component 7 is used to transmit the power of the driving shaft 43 to the transmission shaft 3. The second transmission component 7 includes an active component 71 arranged on the driving shaft 43 and a passive component 72 arranged on each transmission shaft 3; the active component 71 cooperates with the passive component 72 on the transmission shaft 3 of the rope embroidery mechanism entering the working position when the first driving structure 4 enters the driving position, and disengages from the passive component 72 when the first driving structure 4 leaves the driving position.

[0039] The active component 71 is a driving column arranged on the driving shaft 43, and the passive component 82 is a driving column arranged on the transmission shaft 3 of each group of rope embroidery mechanism 1. The driving column and the driving column have matching transmission teeth between their matching surfaces.

[0040] The first sliding drive structure 5 and the second sliding drive structure 6 can adopt existing technical structures, such as hydraulic push rods, pneumatic push rods, electromagnetic push rods, linear motors or screw nut slider assemblies provided with a driving source. The first sliding drive structure 5 described in this embodiment case includes a first driving motor 51 and a first pulley transmission assembly 52 installed on the base frame 8, wherein the first pulley transmission assembly 52 includes a first active pulley connected to the first driving motor 51, a first passive pulley installed on the base frame 8 and a first transmission belt 53, and the rope embroidery assembly 10 is connected to the first transmission belt 53; the second sliding drive structure 6 includes a hydraulic push rod, a pneumatic push rod, an electromagnetic push rod or a linear motor installed between the bracket 41 and the base frame 8. In this embodiment case, the second sliding drive structure 6 is preferably a pneumatic push rod connecting the bracket 41 and the base frame 8.

[0041] In order to facilitate the installation and use of the cord embroidery assembly 10, the cord embroidery assembly 10 can also be provided with a mounting frame 9 for slidingly connecting the base frame 8 and connecting and positioning each cord embroidery mechanism 1.

[0042] In order to facilitate smooth sliding drive, a first guide rail assembly 82 is provided between the base frame 8 and the rope embroidery assembly 10; the guide rail of the first guide rail assembly 82 is installed on the frame 8, and the slider of the first guide rail assembly 82 is connected to the guide rail in cooperation with the installation frame 9. A second guide rail assembly 83 is provided between the bracket 41 and the base frame 8.

[0043] The rope swing structure 13 can adopt the existing technical structure. The rope swing structure 13 includes a swing arm with elastic restoring force, and a rope feeding hole for threading the rope is provided on the swing arm. The elastic restoring force is used to control the tension of the embroidery rope 92 during the rope feeding process, so as to facilitate rope embroidery. Each group of rope embroidery components 10 is provided with a detection structure 14 for detecting the rotation angle of the swing arm provided by the rope swing structure 13, so as to provide the rope feeding device component 20 with rope feeding parameters. The detection structure 14 can be a Hall detector, which determines the tension of the embroidery rope 92 of the corresponding rope embroidery component 10 by detecting the swing angle of the swing arm of the rope swing structure 13. During the rope embroidery rope feeding process, the specific swing angle of the swing arm pulled by the embroidery rope and the tension relationship of the embroidery rope 92 are determined according to actual conditions.

[0044] If the swing angle of the swing arm is detected to be large through the detection structure, and the tension is considered to be too large, it is detected by the system as the parameter of the rope conveying of the corresponding rope conveyor. Then the system controls the rope conveyor to accelerate the rope conveying so as to adjust the rope tension to normal tension, until the swing angle of the swing arm is an appropriate angle amplitude, then the rope tension is considered to be within the normal range, and the corresponding rope conveyor is controlled to convey the rope normally. If the swing angle of the swing arm is detected to be small, the tension is considered to be too small, and it is detected by the system as the parameter of the rope conveying of the corresponding rope conveyor. Then the system controls the rope conveyor to slow down or stop the rope conveying according to the detection situation, so as to adjust the rope tension to normal tension, until the swing angle of the swing arm is an appropriate angle amplitude, then the rope tension is considered to be within the normal range, and the corresponding rope conveyor is controlled to convey the rope normally.

[0045] The rope conveyor assembly 20 may be provided with a linkage sliding structure that slides synchronously with the embroidery rope assembly 10, so as to minimize the influence on the rope tension during the embroidery rope color change process, and facilitate stable rope conveying. The linkage sliding structure of the rope conveyor assembly may be provided with a separate guide rail assembly and a separate sliding drive, which may be specifically linked to the embroidery rope assembly 10.

[0046] In this embodiment, as a preference, each group of rope conveyors 2 includes a driving wheel 21, a clamping wheel 22 matched with the driving wheel 21, and the rope conveyor assembly 20 is provided with a compartment for installing the driving wheel 21 of each group of rope conveyors 2 separately, and a driving motor for driving the driving wheel 21 of each group of rope conveyors 2, and the driving motor is recorded as the second driving motor 24. The second driving motor 24 drives the driving wheels 21 of each group of rope conveyors 2 at the same time, and the driving wheels of each group of rope conveyors 21 can be coaxially installed in the corresponding compartment. Each compartment is provided with a wheel frame 23 that can drive the clamping wheel 22 and the driving wheel 21 to cooperate and separate with each other, and the rope conveyor assembly is provided with a control structure for driving and pressing the corresponding rope conveyor wheel frame 23 into the working position to make the clamping wheel 22 cooperate with the corresponding driving wheel 21, and the wheel frame 23 is provided with a reset spring. Referring to the accompanying drawings, the upper end of the wheel frame 23 is usually rotatably mounted on the partition of the corresponding compartment through a reset torsion spring. The torsion spring drives the wheel frame 23 to separate the clamping wheel 22 from the driving wheel 21. The control structure drives the wheel frame 23 into the working position, and drives the clamping wheel through the wheel frame 23 to make the clamping wheel in the working position cooperate with the driving wheel to drive the embroidery rope transport rope located between the clamping wheel and the driving wheel. The other clamping wheels that have entered the working position are separated from the corresponding driving wheels by the reset spring of the wheel frame, thereby not driving the embroidery rope.

[0047] The partitions can be easily and quickly assembled into corresponding groups of rope conveyors 2 through the partitions, thereby forming rope conveyor assemblies 20. Or the partitions are used to install the drive wheels 21 and divide the rope conveyor assemblies 20 into groups of rope conveyors 2.

[0048] In order to facilitate the conveying of embroidery ropes, the clamping wheel 22 and / or the driving wheel 21 are provided with rope conveying teeth for conveying ropes; the control structure is a pressure rod 25 installed on the base frame 8; a pressure wheel is provided at the joint of the pressure rod 25 and the wheel frame 23, so that the pressure rod 25 can smoothly switch and drive the wheel frame 23 into the working position. The rope conveyor assembly 20 is provided with a connecting plate 26 that connects the rope embroidery assembly 10 and / or the first sliding drive structure 5 to slide with the rope embroidery assembly 10. The connecting plate 26 can constitute a linked sliding structure to drive the rope conveyor assembly 20 to slide synchronously with the rope embroidery assembly 10. In this embodiment, the lower end of the connecting plate 26 is installed on the mounting frame 9 of the rope embroidery assembly 10.

[0049] Each group of cord embroidery mechanisms 1 is also provided with a cord clamp 91 at the rear end, and each group of cord embroidery mechanisms 1 is provided with a first cord guide ring 15 , and the base frame 8 is provided with a second cord guide ring 16 corresponding to the cord embroidery mechanism 1 .

[0050] The support 11 of each set of cord embroidery mechanism 1 includes a bottom plate 17, a vertical plate 18 arranged on the bottom plate 17, and a rear support 19 connected to the bottom plate 17 and / or the vertical plate 18. The looping head 12 is installed on the front side of the bottom plate 17. The cord swing structure 13 includes an elastic swing arm installed on the vertical plate 18. The transmission shaft 3 can be rotatably installed on the rear support 19, and the cord clamp 91 can also be installed on the rear support 19. The first guide rope ring 15 can be arranged on the vertical plate 18.

[0051] The looping head 12 on each group of cord embroidery mechanisms 1 is arranged front and rear of the transmission shaft 3, and each group of cord embroidery mechanisms 1 is arranged in sequence along the axial direction of the swing arm axis of the elastic swing arm provided by the cord swing structure 13 on the mounting frame 9 of the cord embroidery assembly 10. This arrangement can greatly shorten the thickness of the cord embroidery mechanism 1, and can maximize the number of groups of cord embroidery mechanisms in the arrangement direction in terms of the distance of the size.

[0052] The transmission shaft 3 is provided with a positioning structure for positioning the stop position of the transmission shaft 3, so as to stop the transmission shaft 3 at a specific position, so that the passive component 72 on the transmission shaft 3 of the rope embroidery mechanism entering the working position can quickly cooperate with the active component 71 on the drive shaft 43.

[0053] The positioning structure includes a sliding rod 33 provided on each group of cord embroidery mechanisms, a locking assembly provided on the sliding rod 33 and the transmission shaft 3 of the same cord embroidery mechanism 1 and can be locked and disengaged, and a transmission block 45 provided on the bracket 41. The locking assembly includes a positioning slot 31 and a positioning block 32 provided between the transmission shaft 3 and the sliding rod 33. The transmission block 45 slides with the first driving structure 4 and cooperates with the cord embroidery mechanism entering the working position to drive the sliding rod 33 on the cord embroidery mechanism entering the working position to slide, so that the positioning slot 31 and the positioning block 32 are disengaged. The sliding rod 33 is provided with an elastic body for resetting the locking of the positioning slot 31 and the positioning block 32. The sliding rod 33 can be set as a double rod, which can be slidably set in the guide hole provided in the rear support 19 and reset by a reset spring. The reset spring can be set on one of the sliding rods 33 or on the double rods. The positioning slot 31 may be disposed on the transmission shaft 3 , and the positioning block 32 may be disposed on the sliding rod 33 .

[0054] The above-mentioned working position is the position where the head ring of the rope feeding mechanism can cooperate with the machine needle, and at the same time, the passive component 72 on the rope feeding mechanism can cooperate with the active component 71 on the driving shaft 43.

[0055] Before using the rope embroidery device of the utility model, each embroidery rope passes through the rope conveyor 2 corresponding to the rope conveyor assembly 20, the second rope guide ring 16, the first rope guide ring 15, the rope conveying hole on the swing arm of the rope swing structure 13 of the corresponding rope embroidery mechanism 1 of the rope embroidery assembly 10, and the head of the rope is finally clamped by the corresponding rope clamp 91. After each embroidery rope is threaded, it is ready for rope embroidery. Before use, the pneumatic push rod (i.e., cylinder) of the second sliding drive structure 6 of the first drive structure 4 can be lifted by the bracket 41 drive shaft 43 to make the active component 71 on the drive shaft 43 out of the position that can cooperate with the passive component 72.

[0056] When the rope embroidery device of the utility model is used, according to the rope embroidery process, the first driving motor 51 of the first sliding driving structure 5 drives the rope embroidery component 10-rope embroidery mechanism 1 to enter the working position through the first belt wheel transmission component 52, and the pneumatic push rod (i.e., cylinder) of the second sliding driving structure 6 drives the driving shaft 43 downward to the driving position through the bracket 41, just so that the active component 71 of the second transmission component 7 and the passive component 72 cooperate, so as to drive the transmission shaft 3. The transmission block 45 that descends with the bracket 41 simultaneously drives the sliding rod 33 of the rope embroidery mechanism 1 that enters the working position, so that the positioning block 32 on the sliding rod 33 is disengaged from the locking of the positioning card slot 31 on the transmission shaft 3. The third driving motor 42 is started, and the third driving motor 42 drives the driving shaft 43 to rotate through the second belt wheel transmission component 44, and then drives the transmission shaft 3 through the second transmission component 7, and the transmission shaft 3 drives the looping head 12 through the first transmission component to produce the twisting action required for rope embroidery.

[0057] After embroidering the rope of the rope embroidery mechanism 1, the pneumatic push rod (i.e., cylinder) of the second sliding drive structure 6 that is raised and lowered by the first drive structure 4 can drive the bracket 41 and the drive shaft 43 to be lifted, so that the active component 71 on the drive shaft 43 is disengaged from the position that cooperates with the passive component 72 of the transmission shaft of the rope embroidery mechanism. The transmission block 45 that moves upward with the lifting of the bracket 41 is also disengaged from the driving and pressing of the sliding rod 33 of the rope embroidery mechanism. Under the action of the reset spring, the sliding rod 33 of the rope embroidery mechanism slides upward so that the positioning block 32 on the sliding rod 33 is locked with the positioning slot 31 on the transmission shaft 3, thereby ensuring that the transmission teeth on the passive component 72 on the transmission shaft are positioned at a position that can cooperate with the active component 71, in preparation for the next rope embroidery.

[0058] When it is necessary to continue the rope embroidery, according to the rope embroidery process, the first driving motor 51 of the first sliding driving structure 5 drives the other corresponding rope embroidery mechanism 1 of the rope embroidery component 10 to enter the working position through the first pulley transmission component 52. The working process can refer to the above process.
