[0002] Labels are a common paper product used in daily life and are widely used in product labeling and other fields. For example, bottles, cans and other containers need to be labeled before leaving the factory. Therefore, elastic cords need to be attached to the label paper and the elastic cords are put around the mouth of the bottle to hang the label.
[0003] The current method of connecting elastic cords and labels involves workers manually threading the elastic cord through the holes in the label and then manually tying a knot in the elastic cord to complete the cord-label connection. However, manual knotting is inefficient and has high labor costs. Utility Model Content
[0004] The main purpose of this utility model is to propose a rope tag connection device and a tag production equipment, which aims to solve the problems of low efficiency and high labor costs in the existing rope tag connection methods.
[0005] To achieve the above objectives, this utility model proposes a rope label connection device, including a frame, a rope threading mechanism, a knotting mechanism, and a rope feeding mechanism for feeding elastic rope to the rope threading mechanism. Both the rope threading mechanism and the knotting mechanism are mounted on the frame. The rope threading mechanism includes a mounting base with a rope guide hole extending in the z-direction and a placement groove for inserting a label. The rope guide hole and the placement groove are both located within the travel stroke of the rope feeding mechanism as it feeds the elastic rope. The knotting mechanism includes an xz drive platform and a rope clamping part rotatably mounted on the xz drive platform along an axis extending in the z-direction. The rope clamping part is driven by the xz drive platform to move in both the x and z directions, and its travel stroke passes through the placement groove of the rope threading mechanism. The rope clamping part has a first clamping groove for simultaneously inserting and fixing elastic ropes located above and below the label.
[0006] According to some embodiments of the present invention, the rope feeding mechanism includes a rope feeding assembly and a rope feeding shaft for mounting elastic rope coils. The rope feeding assembly includes two rope feeding rollers arranged opposite each other, and a second clamping groove for the elastic rope to pass through is defined between the two rope feeding rollers.
[0007] According to some embodiments of the present invention, the rope feeding mechanism further includes a rope guide tube, one end of which is disposed corresponding to the second clamping groove, and the other end is connected to the mounting base of the rope threading mechanism and disposed corresponding to the rope guide hole.
[0008] According to some embodiments of the present invention, the rope feeding assembly further includes two rope guides, which are respectively disposed on the rope inlet side and the rope outlet side of the two rope feeding rollers, and the rope guides are gradually tapered from their rope inlet end to their rope outlet end.
[0009] According to some embodiments of the present invention, a label clamping mechanism is also included. The label clamping mechanism is located on the side of the threading mechanism facing the knotting mechanism. The label clamping mechanism has a third clamping groove for inserting and fixing a label. The label clamping mechanism is movable in the y-direction, and the moving stroke of the label clamping mechanism passes through the placement groove of the threading mechanism.
[0010] According to some embodiments of the present invention, a rope clamping assembly is also included. The rope clamping assembly is located below the rope threading mechanism and is provided corresponding to the rope guide hole, so that one end of the elastic rope passes through the label paper and is clamped and fixed by the rope clamping assembly.
[0011] According to some embodiments of the present invention, the rope threading mechanism further includes a hollow rope threading component, which is movably disposed within the rope guide hole, and the moving path of the hollow rope threading component passes through the placement groove.
[0012] According to some embodiments of the present invention, the bottom end of the hollow rope threading component is connected to a cutting head, and the cutting head has an annular cutting surface.
[0013] According to some embodiments of this utility model, the annular cutting surface is arranged in a wavy shape.
[0014] In addition, this utility model also provides a label production equipment, including a label storage device, a label conveying device, and a rope-label connecting device as described in any of the above. The label storage device is disposed on the frame and located on one side of the rope threading mechanism in the x direction. The label conveying device is movable in the x direction, and the travel of the label conveying device passes through the placement slots of the label storage device and the rope threading mechanism.
[0015] This utility model has at least the following beneficial effects:
[0016] In this invention, the elastic cord is driven by the cord feeding mechanism to be conveyed downward from the cord guide hole of the cord threading mechanism to the placement slot, and passes through the connection hole of the label paper in the placement slot to connect the elastic cord to the label paper. Then, the cord clamping part of the knotting mechanism moves to the vicinity of the placement slot of the cord threading mechanism under the drive of the xz drive platform, and simultaneously clamps the elastic cords located above and below the label paper. Then, the cord clamping part rotates relative to the xz drive platform, so that the elastic cords located above and below the label paper are stretched and wrapped around the cord clamping part. Then, the cord clamping part moves in the x direction, the elastic cords disengage from the cord clamping part, and the elastic cords located above and below the label paper contract and continue to maintain the intertwined state to achieve the knotting of the elastic cords. This invention achieves the connection between the elastic cord and the label paper by setting the guide hole and the placement groove, and realizes the automatic knotting of the elastic cord by rotating the cord clamping part itself.

[0029] This utility model provides a rope tag connecting device and a tag production equipment. Figures 1 to 6 This invention provides a specific embodiment of a rope tag connecting device and a tag production equipment.
[0030] like Figure 2 , Figure 4 and Figure 6 As shown, this utility model embodiment provides a rope tag connecting device 100, including a frame 1, a rope threading mechanism 2, a knotting mechanism 3, and a rope feeding mechanism for feeding elastic rope to the rope threading mechanism 2. The rope threading mechanism 2 and the knotting mechanism 3 are both mounted on the frame 1. The rope threading mechanism 2 includes a mounting base 21, which has a rope guide hole 211 extending in the z-direction. The mounting base 21 also has a placement groove 212 for inserting and placing a label. The rope guide hole 211 and the placement groove 212... All are within the travel stroke of the rope feeding mechanism 4 conveying the elastic rope. The knotting mechanism 3 includes an xz drive platform 31 and a rope clamping part 32 rotatably mounted on the xz drive platform 31 along an axis extending in the z direction. The rope clamping part 32 is driven by the xz drive platform 31 to move in the x and z directions, and the travel stroke of the rope clamping part 32 passes through the placement groove 212 of the rope threading mechanism 2. The rope clamping part 32 has a first clamping groove that allows elastic ropes located above and below the label paper to extend and be fixed.
[0031] In this invention, the elastic cord is driven by the cord feeding mechanism to be conveyed downward from the cord guide hole 211 of the cord threading mechanism 2 to the placement groove 212, and passes through the connection hole of the label paper in the placement groove 212 to achieve the connection between the elastic cord and the label paper. Then, the cord clamping part 32 of the knotting mechanism 3 moves to the vicinity of the placement groove 212 of the cord threading mechanism 2 under the drive of the xz drive platform 31, and simultaneously clamps the elastic cord located above and below the label paper. Then, the cord clamping part 32 rotates relative to the xz drive platform 31, so that the elastic cord located above the label paper and the elastic cord located below the label paper are stretched and wrapped around the cord clamping part 32. Then, the cord clamping part 32 moves in the x direction, the elastic cord disengages from the cord clamping part 32, and the elastic cord located above and below the label paper contracts and continues to maintain the state of mutual entanglement to achieve the knotting of the elastic cord. This invention achieves the connection between the elastic cord and the label paper by setting the guide hole 211 and the placement groove 212, and realizes the automatic knotting of the elastic cord by rotating the cord clamping part 32 itself. Compared with the existing cord-label connection method of manually completing the knotting of the elastic cord and the connection of the cord-label, it is not only more efficient and saves labor costs, but also produces labels with more standardized elastic cord size and lower defect rate.
[0032] It should be noted that the frame 1 can be provided with multiple rope threading mechanisms 2 and corresponding numbers of knotting mechanisms 3 and rope feeding mechanisms at intervals in the y direction, so that the rope tag connecting device 100 can connect multiple labels and elastic ropes at the same time, which greatly improves the rope tag connecting efficiency.
[0033] Because the placement groove 212 divides the guide hole 211 into two sections, the elastic cord lacks a guiding component after moving from the guide hole 211 to the placement groove 212, which may prevent the elastic cord from passing through the connection hole of the label paper. Therefore, in some embodiments, such as Figure 6 As shown, the rope threading mechanism 2 further includes a hollow rope threading component 22, which is movably disposed within the rope guide hole 211. The movement path of the hollow rope threading component 22 passes through the placement groove 212. With this configuration, the elastic rope is driven by the rope feeding mechanism 4 to move from the rope guide hole 211 into the hollow rope threading component 22. The hollow rope threading component 22 moves downwards through the connecting hole of the label paper located on the placement groove 212, so that one end of the hollow rope threading component 22 is connected to the rope guide hole 211 above the placement groove 212, and the other end is connected to the rope guide hole 211 below the placement groove 212. Simultaneously, the rope feeding mechanism 4 drives the elastic rope to move downwards along the hollow rope threading component 22 through the connecting hole of the label paper. Finally, the hollow rope threading component 22 moves upwards while the elastic rope remains stationary, thereby achieving a rapid connection between the elastic rope and the label paper.
[0034] Elastic cord is typically sold in rolls and is quite long, while only a shorter length is needed for the label. Therefore, the elastic cord needs to be cut after knotting. In some embodiments, such as... Figure 6 As shown, the bottom end of the hollow cord threading component 22 is connected to a cutting head 221, which has an annular cutting surface. After the elastic cord passes through the label paper connection hole, the cord clamping part 32 of the knotting mechanism 3 simultaneously clamps the elastic cord located above and below the label paper. Then, the cord clamping part 32 rotates relative to the xz drive platform 31, causing the elastic cord above and below the label paper to be stretched and wrapped around the cord clamping part 32, driving the label paper to detach from the placement groove 212. At this time, the elastic cord forms a certain angle with the placement groove 212. After the cord clamping part 32 completes the knotting of the elastic cord, the hollow cord threading component 22 moves downward again, and the cutting head 221 applies pressure to the elastic cord and cuts the elastic cord through the cutting surface to achieve the cutting of the elastic cord. With this configuration, by integrating the cutting function into the cutting head 221 of the hollow cord threading component 22, the structure is simpler and the cost is lower compared to setting a separate cutting component. Furthermore, the cutting head 221 on the hollow rope threading component 22 can also be used to punch holes in the label paper. There is no need to set up additional punching components. Punching the label paper before placing it in the placement slot 212 can further reduce costs. Moreover, combining the punching step with the rope threading step reduces the number of operation steps and improves the rope label connection efficiency.
[0035] Specifically, the annular cut surface is wavy, which makes the contact area between the annular cut surface and the label paper smaller and the pressure greater when punching, thus making punching easier.
[0036] After the clamping part 32 clamps the elastic cords located above and below the label paper simultaneously, it rotates relative to the xz drive platform 31, causing both ends of the elastic cords to be stretched and wrapped around the clamping part 32. However, if the elastic cord located below the label paper is not properly secured, it will be unable to be stretched, relying solely on the contraction of the upper elastic cord, resulting in an insufficiently secure knot that is prone to loosening. Therefore, in some embodiments, such as... Figure 3 and Figure 6 As shown, the rope label connecting device 100 also includes a rope clamping assembly 5. The rope clamping assembly 5 is located below the rope threading mechanism 2 and is disposed corresponding to the rope guide hole 211, so that one end of the elastic rope passes through the label paper and is clamped and fixed by the rope clamping assembly 5. By clamping and fixing the elastic rope located below the label paper by the rope clamping assembly 5, both ends of the elastic rope can be stretched and wrapped around the rope clamping part 32. When the elastic rope is released from the rope clamping part 32, it will contract and continue to maintain the intertwined state to achieve the knotting of the elastic rope.
[0037] Because the space within the placement slot 212 is small, the rope clamping part 32 cannot easily extend into the placement slot 212 to simultaneously clamp the elastic rope located above and below the label paper. Therefore, in some embodiments, such as Figure 4 As shown, the rope-tag connecting device 100 also includes a tag-clamping mechanism 6. The tag-clamping mechanism 6 is located on the side of the rope-threading mechanism 2 facing the knotting mechanism 3. The tag-clamping mechanism 6 has a third clamping groove for the tag paper to be inserted and fixed. The tag-clamping mechanism 6 is movable in the y-direction, and its movement passes through the placement groove 212 of the rope-threading mechanism 2. With this configuration, by first clamping the tag paper with the tag-clamping mechanism 6 and moving it in the y-direction, the tag paper is fixed in place to avoid affecting the knotting of the elastic rope. On the other hand, removing the tag paper from the placement groove 212 will bring the elastic ropes above and below the tag paper closer together, making it easier for the rope-clamping part 32 to clamp the upper and lower elastic ropes simultaneously.
[0038] To prevent the elastic cord from detaching from the clamping part 32 during winding, in some embodiments, such as Figure 4As shown, the cord clamping part 32 includes two cord clamping members 321 hinged together. Each cord clamping member 321 has a groove for the elastic cord above and below the label paper to be wound and placed. The groove is located near the hinge end of the cord clamping member 321. With this configuration, the free ends of each cord clamping member 321 first come together to clamp the elastic cord located above and below the label paper. Then, the cord clamping part 32 rotates so that the elastic cord is wound around the cord clamping member 321 once. Next, the free ends of each cord clamping member 321 move away from each other, so that the elastic cord moves towards the hinge end of the cord clamping member 321 under the action of contraction force until it enters the groove, so as to prevent the elastic cord from detaching from the cord clamping member 321 during subsequent rotation of the cord clamping part 32.
[0039] The specific structure of the rope feeding mechanism 4 is not limited, as long as it ensures that the rope feeding mechanism 4 can actively feed the elastic rope. For example, in some embodiments, such as... Figure 2 As shown, the rope feeding mechanism includes a rope feeding assembly 41 and a rope feeding shaft 42 for mounting the elastic rope coil. The rope feeding assembly 41 includes two oppositely arranged rope feeding rollers 411, with a second clamping groove defined between the two rope feeding rollers 411 for the elastic rope to pass through. With this configuration, since the elastic rope is clamped by the two rope feeding rollers 411, the rotation of the two rope feeding rollers 411 drives the elastic rope to move into the rope guide hole 211 of the rope threading mechanism 2, completing the rope feeding step.
[0040] Because the elastic rope is coiled, the free end of the elastic rope will bend during feeding, making it difficult to enter the guide hole 211. Therefore, in some embodiments, such as... Figure 2 As shown, the rope feeding mechanism also includes a rope guide tube 43. One end of the rope guide tube 43 is disposed corresponding to the second clamping groove, and the other end is connected to the mounting base 21 of the rope threading mechanism 2 and is disposed corresponding to the rope guide hole 211. The elastic rope is driven by the rope feeding roller 411 to move to the rope guide tube 43, and enters the rope guide hole 211 through the rope guide tube 43. This arrangement improves the efficiency of the elastic rope entering the rope guide hole 211 through the guidance of the rope guide tube 43. Furthermore, the rope guide tube 43 can be bent, allowing the rope feeding assembly 41 to be disposed on one side or diagonally above the rope threading mechanism 2, without restricting the rope feeding assembly 41 to be disposed directly above the rope guide hole 211.
[0041] Because the free end of the elastic cord is bent, it is difficult for the elastic cord on the coil to enter the second clamping groove. Therefore, in some embodiments, such as... Figure 2As shown, the rope feeding assembly 41 further includes two rope guides 412, which are respectively disposed on the rope inlet side and rope outlet side of the two rope feeding rollers 411. The rope guides 412 are tapered from their rope inlet end to their rope outlet end. Since the diameter of the rope inlet end of the rope guide 412 is larger than the diameter of the rope outlet end, the bent elastic rope can enter the rope guide 412 and then enter the second clamping groove defined by the two rope feeding rollers 411 via the rope guide 412. Then, driven by the rope feeding rollers 411, the elastic rope passes through the other rope guide 412 and enters the rope guide tube 43.
[0042] In addition, such as Figure 1 As shown, this utility model also provides a label production equipment 1000, including a label storage device 200, a label conveying device 300, and the rope label connecting device 100. The label storage device 200 is disposed on the frame 1 and located on one side of the rope threading mechanism 2 in the x direction. The label conveying device 300 is movable in the x direction, and the moving stroke of the label conveying device 300 passes through the placement groove 212 of the label storage device 200 and the rope threading mechanism 2.
[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
