[0058] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0059] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0060] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0061] like Figures 1 to 6 As shown, it is the optimal embodiment of the present invention, an automatic tassel threading and knotting mechanism, including: a feeding mechanism 1, a tassel taking mechanism 2, a tassel hooking mechanism 3, a tassel assembling mechanism 4 and a support frame 5.

[0062] like Figure 3 As shown, a plurality of tassels are hung on the feeding mechanism 1, and the tassels include a tassel hanging belt 210 and a tassel fringe 220. The feeding mechanism 1 includes: a turntable 11, a rotating platform 12 and a first driving mechanism 13.

[0063] A plurality of suspension columns 111 are provided around the turntable 11, and the suspension columns 111 extend radially outward along the turntable 11. The tassels are suspended on the suspension columns 111 through the tassel suspension belts 210. Preferably, the tassel suspension belts 210 are suspended on two adjacent suspension columns 111, and the outer ends of the two adjacent suspension columns 111 are closed inward, which is convenient for hanging tassels and expanding the gap between the tassel suspension belts, making it convenient for the tassel taking mechanism 2 to reach into the gap to take the tassels, making the trajectory of the tassel movement more controllable, and greatly improving the success rate of the equipment in automatically threading the tassels.

[0064] A rotating platform 12 is disposed below the turntable 11 and is fixedly connected to the turntable 11. A first drive mechanism 13 is disposed below the rotating platform 12 and is rotatably connected to the rotating platform 12 to drive the rotating platform 12 to rotate. The drive mechanism 13 may be a stepper motor that controls the turntable 11 to achieve a higher degree of rotational accuracy. This allows for smoother rotation of the turntable 11, ensuring precise positioning and preventing tassel sway.

[0065] like Figure 4 The tassel removing mechanism 2 is located on one side of the feeding mechanism 1, and is used to remove the tassels on the feeding mechanism 1. Specifically, the tassel removing mechanism 2 includes: a first clamping cylinder 21 and a second driving mechanism 22. The first clamping cylinder 21 is provided with two opposite first clamping pieces 211 at one end close to the feeding mechanism 1, which are used to remove the tassel hanging belt 210. The design of using the opening and closing of the two first clamping pieces 211 of the first clamping cylinder 21 to remove the tassels provides redundant space, which partially reduces the accuracy requirements for equipment operation.

[0066] The first clamping cylinder 21 is arranged on the second driving mechanism 22, and the second driving mechanism 22 drives the first clamping cylinder 21 to move closer to or away from the feeding mechanism 1. The second driving mechanism 22 includes a slider 221, a guide rail 222 and a pneumatic push rod 223. The slider 221 is movably arranged on the guide rail 222. The pneumatic push rod 223 is fixedly connected to the slider 221. The pneumatic push rod 223 can push the slider 221 to move along the guide rail 222. The first clamping cylinder 21 is arranged on the slider 221. The second driving mechanism 22 has a simple structure and is easy to operate. The two first clamping pieces 211 are each provided with a push piece 212 on one side close to the feeding mechanism 1. The two push pieces 212 push the tassel hanging belt 210 to the outside of the bookmark 100, so that the tassel hooking mechanism 3 can hook the tassel hanging belt 210.

[0067] A stop plate is provided below between the feeding mechanism 1 and the tassel removing mechanism 2. When the tassel removing mechanism 2 takes the tassel hanging belt 210 and drags it backward, the tassel fringe 220 below cannot continue to move backward due to the obstruction of the stop plate, so that the tassel hanging belt 210 on the tassel removing mechanism 2 slides onto the bookmark 100.

[0068] like Figure 5 As shown, the tassel hooking mechanism 3 is arranged below the tassel removing mechanism 2, and a bookmark 100 is placed between the tassel hooking mechanism 3 and the tassel removing mechanism 2. A bookmark hole 110 is provided at one end of the bookmark 100, and a supporting portion 51 is provided below the bookmark 100. A hollow portion is provided on the supporting portion 51, and the hollow portion corresponds to the bookmark hole 110.

[0069] The tassel hook mechanism 3 moves upward through the bookmark hole 110, takes the tassel mechanism 2 to hang the tassel hanging band 210 on the bookmark 100, and pushes the tassel hanging band 210 toward the tassel hook mechanism 3, and the tassel hook mechanism 3 drives one end of the tassel hanging band 210 downward through the bookmark hole 110. The tassel hook mechanism 3 separates so that the tassel hanging band 210 forms a triangular structure. Specifically, the tassel hook mechanism 3 includes: two vertically arranged crochet hooks 31, a horizontal sliding mechanism 32 and a lifting mechanism 33. The needle head 311 of the crochet hook 31 faces the feeding mechanism 1. The two crochet hooks 31 are arranged on the horizontal sliding mechanism 32. The horizontal sliding mechanism 32 drives the two crochet hooks 31 to approach or move away from each other. The horizontal sliding mechanism 32 is arranged on the lifting mechanism 33. The lifting mechanism 33 drives the horizontal sliding mechanism 32 to move up and down.

[0070] The design of using a pair of hooks 31 to hook and separate the tassel hanging band 210 solves the problems of limited space and the flexibility and difficulty in controlling the tassel hanging band 210 during knotting. The lifting mechanism 33 is formed larger than the vertical distance between the turntable 11 and the first clamping cylinder 21, which can lift the tassel 220 into the triangular structure of the tassel hanging band 210 to facilitate the passage of the second clamping cylinder 41. Tassels of different sizes can be adjusted by changing the height of the turntable 11 and the travel of the lifting mechanism 33, without having to modify the mechanical structure of the equipment.

[0071] like Figure 6 As shown, the tassel assembly mechanism 4 passes the tassel 220 through the hole to form a triangular structure, completing the tassel assembly. Specifically, the tassel assembly mechanism 4 includes: a second clamping cylinder 41 and a second sliding mechanism 42. The second clamping cylinder 41 is provided with two opposite second clamping pieces 411 at one end close to the feeding mechanism 1 for clamping the tassel 220. The second clamping cylinder 41 is provided on the second sliding mechanism 42. The second sliding mechanism 42 drives the second clamping cylinder 41 to move closer to or away from the feeding mechanism 1.

[0072] The feeding mechanism 1 , the tassel taking mechanism 2 , the tassel hooking mechanism 3 and the tassel assembling mechanism 4 are all arranged on the supporting frame 5 .

[0073] The method of using the automatic tassel threading and knotting mechanism of the present invention is as follows: Figures 7 to 22 As shown, the following steps are included: S1, hanging the tassel on the hanging column 111 of the feeding mechanism 1, and the rotating platform 12 of the feeding mechanism 1 drives the tassel to rotate to the feeding position;

[0074] S2, the first clamping claw cylinder 21 of the tassel removing mechanism 2 moves forward, driving the two opposite first clamping pieces 211 to extend into the tassel hanging belt 210, and the two opposite first clamping pieces 211 move in opposite directions at the same time, so that the tassel hanging belt 210 opens;

[0075] S3, the two hooks 31 of the tassel hooking mechanism 3 move upward together and pass through the bookmark hole 110. At the same time, the first clamping cylinder 21 drives the tassel to move backward. During the backward movement, the tassel hanging belt 210 slides onto the bookmark 100 and is located on one side of the needle head 311 of the hook 31.

[0076] S4, the two push pieces 212 of the first clamping cylinder 21 push the tassel hanging belt 210 on both sides of the hook 31 to the outside of the bookmark 100, and under the hanging effect of the tassel 220, the tassel hanging belt 210 is tightly hung on the hook 31;

[0077] S5, the two crochet hooks 31 move downward, the needle head 311 hooks the tassel hanging belt 210 and leads the tassel hanging belt 210 to continue to move downward, the crochet hook 31 moves downward through the bookmark hole 110, and then the two crochet hooks 31 move away from each other, so that the tassel hanging belt 210 expands into a triangle;

[0078] S6. The second clamping cylinder 41 of the tassel assembly mechanism 4 moves forward, driving the second clamping piece 411 on the second clamping cylinder 41 to pass through the triangular tassel hanging belt 210. The two second clamping pieces 411 move in opposite directions to clamp the tassel 220. The two hooks 31 move in opposite directions to release the tassel hanging belt 210. The second clamping cylinder 41 drives the tassel 220 to pass through the triangular tassel hanging belt 210 and tighten it diagonally backward, fastening the tassel hanging belt 210 to realize the assembly of the tassel.

[0079] The automatic tassel threading and knotting mechanism of the present invention is simple in movement and occupies little space. The tassel taking mechanism removes the tassel from the turntable feeding mechanism through the first clamping claw cylinder. During the return process, the tassel hanging belt is hung on the crochet hook. The tassel placed on the bookmark is pushed out again by a round trip. No additional mechanism is required to realize this function, which reduces the complexity of the mechanism. The tassel hooking mechanism is equipped with a detachable crochet hook. After the tassel hanging belt is hooked from the bookmark hole and moved downward, the crochet hook is separated, providing sufficient space for the assembly of the tassel. The tassel assembling mechanism moves horizontally and passes the tassel fringe through the tassel hanging belt hooked by the detached crochet hook. By threading the tassel and knotting the tassel, the function of assembling the tassel is realized. The mechanism structure adopted by the present invention is simple and effective. The automatic assembly of the tassel is realized through the ingenious cooperation of multiple mechanisms, which saves labor and improves work efficiency.

[0080] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical spirit of this invention. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
