Description

Technical Field

[0001] The utility model relates to a multi-rope embroidery device. Background Art

[0002] Rope embroidery is used to sew ropes on fabrics as decorations. In order to enrich the needs of rope embroidery, multiple rope embroidery pieces are usually combined together to form multi-color rope embroidery.

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 embroidery of this structure can usually only be provided with three groups, and the upper limit is barely set to four groups.

[0004] Each rope feeder (rope retracting and releasing mechanism) of each rope embroidery component is equipped with an independent driving motor, which results in a large rope feeder, which is not convenient for compact arrangement of more than three groups. According to the existing embroidery machine structure, the number of rope feeders is no more than three groups, otherwise the reasonable layout of the entire device will be greatly sacrificed. Therefore, the existing multi-rope rope embroidery device requires two motors for each rope embroidery component, and six motors for three groups. The number of motors used is large, the cost is high, and the layout is not reasonable, the volume is large, the number of rope feeders for rope embroidery is limited, and it is not convenient to install on the embroidery machine head with a small space.

[0053] See also Figure 1-16In the utility model, the front in the locative term is the direction in which the feeding mechanism 6 drives the corresponding cording mechanism 1 to move forward toward the cording embroidery machine needle, and conversely, the rear is the direction in which the feeding mechanism 6 drives the corresponding cording embroidery mechanism 1 to move away from the cording embroidery machine needle.

[0054] A multi-cord embroidery device includes a cord embroidery assembly 10 having at least two cord embroidery mechanisms 1, a base frame 8, a transmission assembly 7, a drive assembly 4, a sliding switching mechanism 5, a feeding mechanism 6, and a cord feeder assembly 20. Each cord embroidery mechanism 1 includes a support 11, a looping head 12 disposed on the support 11, and a tension controller 13. The cord feeder assembly 20 includes cord feeders 2 corresponding to the number of cord embroidery mechanisms 1.

[0055] The base frame 8 is used to position and install various components. 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 the necessary installation parts or installation structures for installing and connecting various components. The base frame 8 can be composed of a plurality of base frames connected with different functional components. A lifting mechanism 9 for lifting the entire device can also be connected to the base frame 8. The lifting mechanism 9 usually includes a connecting frame connected to the base frame 8 through a guide rail assembly. The connecting frame can be connected to the corresponding part of the embroidery machine body or head. A cylinder for driving the base frame 8 to lift is provided between the connecting frame and the base frame 8.

[0056] The transmission assembly 7 is arranged on each group of rope embroidery mechanisms 1 and is used to drive the loop head 12. The transmission assembly 7 includes a transmission shaft 71. A transmission structure for driving the loop head 12 is provided between the transmission shaft 71 and the loop head 12. The transmission structure is usually a transmission pulley and a transmission belt arranged between the loop head 12 and the transmission shaft 3, preferably a synchronous belt. Of course, it can also be replaced by other existing solutions that are easy to implement.

[0057] The driving assembly 4 is used to drive the looping head 12 of the cord embroidery mechanism 1 into the working position. The driving assembly 4 includes a first driving motor 41 installed on the base frame 8, a driving shaft 42 connected to the first driving motor 41, and a mutually cooperating and transmission-capable bite block structure is respectively provided between the driving shaft 42 and the transmission shaft 71. The bite block structure in the utility model can adopt the existing technical structure, specifically to meet the cord embroidery mechanism 1 sliding forward with the feed mechanism 6 driving to make the transmission shaft 71 and the drive shaft 42 cooperate for transmission, and the cord embroidery mechanism 1 sliding backward with the feed mechanism 6 driving to make the transmission shaft 71 and the drive shaft 42 disengage from the transmission cooperation. For example, it can be two semicircular protrusions that fit together to form a complete circle, that is, a first semicircular protrusion extending downward in the axial direction is provided on the driving shaft 42, and a second semicircular protrusion extending upward in the axial direction is provided on the transmission shaft 71. The first semicircular protrusion can form a complete cylinder by sliding and cooperating with the second semicircular protrusion. The first and second semicircular protrusions are slid to the working position along with the feeding needle of the rope embroidery mechanism 1 through the transmission shaft 71, so that the driving shaft 42 cooperates with the first and second semicircular protrusions at the driving shaft 42 to realize transmission; the transmission shaft 71 slides in the opposite direction of the rope embroidery mechanism 1, so that the transmission shaft 71 is completely separated from the first and second semicircular protrusions at the driving shaft 42.

[0058] In order to arrange the components compactly, the driving assembly 4 also includes a second pulley transmission assembly 43 connecting the driving shaft 42 and the shaft of the first driving motor 41; the engaging block structure includes at least one first protrusion 44 arranged at the corresponding end of the driving shaft 42, and at least one second protrusion 45 arranged on the transmission shaft 71 and cooperating with the first protrusion 44, and the first protrusion 44 and the second protrusion 45 are arranged in a coordinated manner; the positioning structure 53 provided in each group of rope embroidery mechanism 1 includes a positioning block 58 that cooperates with the second protrusion 45 on the transmission shaft 71 to position the transmission shaft 71.

In this embodiment, one first protrusion 44 is provided and centrally arranged on the driving shaft 42, and two second protrusions 45 are provided. The groove between the two second protrusions 45 symmetrically arranged at the corresponding ends of the transmission shaft 71 constitutes a slot that matches the first protrusion 42. The slot can also be used to cooperate with the positioning structure 53 to locate the initial position of the transmission shaft 42, so that the rope embroidery mechanism 1 can quickly and smoothly cooperate with the first protrusion 44 on the driving shaft when feeding into the working position.

[0059] The sliding switching mechanism 5 is used to drive the rope embroidery component 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 arranged on the base frame 8. The rope embroidery mechanisms 1 are arranged side by side on the sliding seat 52 in sequence. The rope embroidery mechanism 1 can be slid toward the working position, that is, the machine needle moves forward and backward on the sliding seat 52.

[0060] The feeding mechanism 6 is used to drive the corresponding cord embroidery mechanism 1 that has entered the cord feeding position to slide forward toward the machine needle into the working position and cooperate with the machine needle, and transmit the transmission by sliding so that the bite block structure between the transmission shaft 71 of the corresponding cord embroidery mechanism 1 and the driving shaft 42 cooperates; and is used to drive the corresponding cord embroidery mechanism 1 that has entered the cord feeding position to slide backward and exit the working position, and release the transmission by sliding so that the bite block structure between the transmission shaft 71 of the corresponding cord embroidery mechanism 1 and the driving shaft 42 disengages the cooperation. The feeding mechanism 6 includes a third driving structure 61 that is arranged on the base frame 8 and drives the corresponding cord embroidery mechanism 1 that has entered the cord feeding position to slide.

[0061] In order to facilitate the transmission shaft 71 and the driving shaft 42 to quickly cooperate, the sliding seat 52 is provided with a positioning structure 53 for positioning the transmission shaft 71 of each group of cord embroidery mechanisms 1, and the transmission shaft 71 of each group of cord embroidery mechanisms 1 cooperates with the positioning structure 53 when the working position is separated. The transmission shaft 71 separated from the working position is positioned by the positioning structure 53, so that the corresponding block of the bite block structure on the transmission shaft 71, that is, the second protrusion 44, remains in a state of cooperation with the first protrusion 42, so that when it is used next time, the cord embroidery mechanism 1 can be quickly and directly driven into the working position by the feeding mechanism, so that the transmission shaft 71 and the bite block structure on the driving shaft 42, that is, the first and second cams, can be quickly cooperated.

[0062] The above-mentioned cording position is the position where a corresponding cording mechanism 1 of the cording assembly 10 is driven by the sliding switching mechanism 5 to align with the cording machine needle; the above-mentioned working position is the position where a cording mechanism 1 enters the cording position and is driven by the 1x feeding mechanism 6 to slide into a position that can cooperate with the cording machine needle.

That is, the power driver 36 drives the driving arm 35 to drive the transmission arm 39 of the cord embroidery mechanism 1 into the working position, so that the rope hook 34 on the hook handle arm 37 of the second clamping plate 39 extends out to hook the rope, and after hooking the rope, the second clamping plate 39 is reset by the first return spring 18, so that the rope hook 34 cooperates with the first clamping plate 32, clamps the rope between the rope hook 34 and the first clamping plate 32, and positions the rope. As a preferred embodiment, the rope will be clamped between the rope hook 34 and the clamping groove of the first clamping plate 32.

The rope conveying driving structure 25 comprises a driving wheel 21 for conveying ropes, a rope conveying driving motor 24 for the driving wheel 21, and a mounting plate 26 for the rope conveying driving motor 24. In order to facilitate compact structure, the rope conveying driving motor 24 is connected to the driving wheel 21 through a pulley and a belt to drive the driving wheel 21 to rotate the rope conveying. When in use, the sliding switching mechanism 5 drives the sliding seat 52 to drive the rope embroidery assembly 10 to slide, and at the same time, drives the rope conveyor assembly 20 to slide synchronously through the support arm 54 connected to the sliding seat 52, so as to avoid the influence of the rope tension on the process of driving the rope embroidery assembly 10 to slide and switch the corresponding rope embroidery mechanism 1 as much as possible.

The driving arm 35 can pass through the belt loop of the sliding drive belt 56 to facilitate a compact structure.

[0075] A first guide rail assembly 81 is provided between the base frame 8 and the sliding seat 52 ; a second guide rail assembly 57 is provided between the support 11 and the sliding seat 52 .

[0076] Each set of cord embroidery mechanisms 1 is provided with a first cord guide ring 15 .

[0077] The support 11 of each set of rope embroidery mechanism 1 includes a base plate 17 and a vertical plate 16 arranged on the base plate 17. The loop head 12 is installed on the front side of the base plate 17. The tension controller 13 includes a swing arm with elastic restoring force installed on the vertical plate 16. The transmission shaft 71 is rotatably installed on the rear side of the vertical plate 16.

[0078] The tension controller 13 can adopt the existing technical structure, and the swing arm is provided with a rope feeding hole for threading the rope, and the tension of the embroidery rope during the rope feeding process is controlled by the elastic restoring force, 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 tension controller 13, so as to provide the rope feeding device component 20 with the rope feeding parameters. The detection structure 14 can be a Hall detector, which determines the tension of the embroidery rope of the corresponding rope embroidery component 10 by detecting the swing angle of the swing arm of the tension controller 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 are determined according to the actual situation.

[0079] 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.

[0080] The looping head 12 on each set of cord embroidery mechanisms 1 is arranged in front and behind the transmission shaft 71 , and each set of cord embroidery mechanisms 1 is arranged in sequence on the sliding seat 52 along the axial direction of the swing arm shaft provided on the tension controller 13 .

[0081] As a further preferred embodiment, the utility model further comprises a rope cutting mechanism 91. The rope cutting mechanism 91 can adopt a rope cutting mechanism of the prior art structure. The rope cutting mechanism 91 is usually installed at a corresponding position of a corresponding machine head to facilitate rope cutting.

[0082] Before the rope embroidery device of the utility model is used, each embroidery rope is inserted from the entrance above each group of rope feeders 2, and is transmitted from the exit, passing through the rope feed wheel 22, and then sequentially passes through the first guide rope ring 15, the rope feed hole on the swing arm of the tension controller 13 of the corresponding rope embroidery mechanism 1 of the rope embroidery assembly 10, and the head ring 13, and after each embroidery rope is put through, it is ready for rope embroidery.

[0083] See also Figure 6When the rope embroidery device of the utility model is used, according to the rope embroidery process, the sliding drive motor 55 of the sliding switching mechanism 5 drives the sliding seat 53 through the first pulley transmission assembly 50, so that a rope embroidery mechanism 1 of the rope embroidery assembly 10 enters the rope embroidery position. The feeding drive motor 62 of the feeding mechanism 6 drives the corresponding rope embroidery mechanism 1 located at the rope embroidery position to advance toward the machine needle and maintain it in the working position to perform rope embroidery through the third swing rod 63, the connecting rod 65 and the swing rod 64 of the third driving structure 61. The transmission shaft 71 of the corresponding rope embroidery mechanism 1 that enters the rope embroidery position cooperates with the driving shaft 42 through the bite block structure, that is, the second protrusion 45 cooperates with the first protrusion 44 to realize transmission. The transmission shaft 71 drives the looping head 12 through the transmission structure to produce the twisting action required for rope embroidery and cooperate with the machine needle to perform rope embroidery.

[0084] See also Figure 7 After embroidering the rope of the rope embroidery mechanism 1, the rope can be moved to a position where the rope hook 34 of the second clamping plate 33 can be hooked by the movement of the embroidery frame. The power driver 36 is actuated to cause the driving arm 35 to push the transmission arm 39 of the second clamping plate 32 on the rope embroidery mechanism 1. The rope hook 34 slides downward to hook the rope through the action of the intermediate connecting arm 38 and the hook handle arm 37. After hooking the rope, the power driver 36 drives the driving arm 35 to reset. The second clamping plate 34 slides upward and resets under the action of the first reset spring 18, and cooperates with the first clamping plate 32 to clamp the rope. The rope cutting mechanism 91 can cut the rope while clamping the rope or after clamping the rope. After clamping and cutting the rope, the feed drive motor 62 of the feed mechanism 6 disengages from the rope embroidery mechanism 1 entering the working position through the third rocker arm 63, the connecting rod 65 and the swing rod 64 of the third driving structure 61, and the rope embroidery mechanism 1 is reset and retracted under the action of the second reset spring 19. The second protrusion 45 on the transmission shaft 71 of the retracted rope embroidery mechanism 1 is positioned by the positioning block 58 of the positioning structure 54.

[0085] When it is necessary to continue the rope embroidery, according to the rope embroidery process, the sliding drive motor 55 of the sliding switching mechanism 5 drives the rope embroidery assembly 10 and another corresponding rope embroidery mechanism 1 to enter the working position through the first pulley transmission assembly 50. The working process can refer to the above process.

[0086] When the cord embroidery assembly 10 moves, the sliding seat 52 drives the cord conveyor assembly 20 to move synchronously accordingly through the support arm 54 .

[0087] See also Figure 6When the feeding mechanism 6 drives the corresponding cord embroidery mechanism 1 to move forward to the needle and maintain it at the working position, the fourth driving structure linked with the third driving structure 61 drives the cord-feeding driving structure 25 to cooperate with the corresponding cord-feeding device 2 to feed the cord. Specifically, the feeding driving motor 62 drives the sliding plate 27 through the fourth swing rod 28 to drive the cord-feeding driving structure 25 to slide toward the corresponding cord-feeding device 2 of the cord-feeding device assembly 20, so that the driving wheel 21 of the cord-feeding driving structure 25 cooperates with the cord-feeding wheel 22 of the corresponding cord-feeding device 2, and then the cord is fed through the cord-feeding driving motor 24 as needed.

[0088] See also Figure 7 When the feed drive motor 62 of the feed mechanism 6 disengages from the rope embroidery mechanism 1 entering the working position through the third rocker arm 63, the connecting rod 65 and the swing rod 64 of the third driving structure 61, the sliding plate 27 drives the rope feeding drive structure 25 to retreat under the action of the third reset spring 82, and the driving wheel 21 of the rope feeding drive structure 25 disengages from the rope feeding wheel 22 of the corresponding rope feeding device 2, and stops feeding the rope.
