However, when the cutting component is working and the transparent paper and the wire are in a stop position, the transparent paper will have a certain degree of relaxation and shaking, and the wire will also have a certain degree of relaxation and shaking. When the cutting component works at a high frequency, the wire may jump or deviate, resulting in the phenomenon of the transparent paper wire of cigarette packs and cartons being misaligned.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and 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 should not be understood as limiting the scope of protection of the present invention.

[0028] refer to Figure 1 and Figure 3As shown, in some embodiments of the wire conveying device provided by the utility model, the wire conveying device includes a frame 1, a roller 2 and a limiting structure 4, the roller 2 is installed on the frame 1, and the outer periphery of the roller 2 is provided with a circumferential groove 21, the groove 21 is used to wind the wire 3, the roller 2 is configured to rotate relative to the frame 1 to drive the wire 3 to move, and the limiting structure 4 is configured to cooperate with the roller 2 to limit the wire 3 so that the wire 3 remains in the groove 21 during the movement.

[0029] The cooperation of the roller 2 with the groove 21 and the limiting structure 4 can ensure the stability of the wire 3 during the transmission process. The limiting structure directly acts on the wire through the pressure wheel 42 to prevent it from escaping from the groove 21, that is, to prevent the occurrence of wire jump, thereby improving the reliability of the transmission of the wire 3.

[0030] In some application scenarios that require high-precision positioning and stable transmission, such as automated cigarette packaging production lines, the stable transmission of the pull wire 3 helps to ensure the quality of cigarette packaging, reduce the occurrence of problems such as wire misalignment and loose packs caused by wire jumps, and improve the stability of cigarette packaging quality.

[0031] In some embodiments, the limiting structure 4 includes a mounting shaft 41 and a pressure wheel 42, the mounting shaft 41 is connected to the frame 1, the pressure wheel 42 is rotatably mounted on the mounting shaft 41, and, in the radial direction of the roller 2, the outer peripheral surface of the pressure wheel 42 is fitted with the top of the groove 21 to limit the pull wire 3 in the groove 21.

[0032] By setting the pressing wheel 42 to be rotatable, when the roller 2 rotates or the wire 3 moves, the roller 2 or the wire 3 contacts the pressing wheel 42, which can drive the pressing wheel 42 to rotate together, thereby reducing the direct friction between the pressing wheel 42 and the wire 3 or the roller 2, helping to reduce the wear of the above-mentioned components and extend their service life. In addition, during the rotation of the pressing wheel 42, it can more evenly distribute the pressure acting on the wire 3, avoiding wear caused by local overpressure.

[0033] In some embodiments, the radial distance between the roller 2 and the pressure wheel 42 is adjustable.

[0034] In practical applications, the distance between the roller 2 and the pressure wheel 42 can be adjusted according to production requirements. For example, the radial distance between the roller 2 and the pressure wheel 42 can be set to be different for wires 3 of different diameters or thicknesses, so that the pressure wheel 42 can just confine the wire 3 in the groove 21 without squeezing the wire 3, so that the wire 3 can be smoothly transmitted while ensuring stability without wire jumps. Such a setting improves the flexibility and adaptability of the wire transmission device, reduces the need to replace the entire set of equipment components due to replacing wires of different specifications, and helps to reduce costs.

[0035] refer to Figure 1 and Figure 2 As shown, in some embodiments, the wire conveying device also includes a first mounting seat 5 for mounting the roller 2 and a second mounting seat 6 for mounting the limiting structure 4. In the radial direction of the roller 2, the distance between the first mounting seat 5 and the second mounting seat 6 is adjustable.

[0036] By adjusting the distance between the first mounting seat 5 and the second mounting seat 6, the radial distance between the roller 2 and the pressure wheel 42 can be adjusted. When the wire 3 is wound, the distance between the first mounting seat 5 and the second mounting seat 6 is increased to facilitate the operation of the staff. Alternatively, the first mounting seat 5 and the second mounting seat 6 can be set to have an adjustable relative mounting angle, and the positions of the first mounting seat 5 and the second mounting seat 6 can be staggered by adjusting the angle between them, so that the staff can perform the winding operation.

[0037] refer to Figure 1 and Figure 2 As shown, in some embodiments, the wire transmission device also includes a pull ring 7, which is installed on a side of the first mounting seat 5 away from the second mounting seat 6. The pull ring 7 is configured to receive external pulling force and drive the first mounting seat 5 to move to adjust the distance between the first mounting seat 5 and the second mounting seat 6.

[0038] The design of the pull ring 7 enables the staff to directly apply force to the pull ring 7 to adjust the position of the first mounting seat 5, thereby changing the distance between the roller 2 and the pressure wheel 42. This method is simple and intuitive to operate, does not require additional tools, and improves the overall convenience and efficiency of the equipment.

[0042] In some embodiments, the packaging machine further comprises a transparent paper conveying device, which is configured to move synchronously with the pull wire conveying device to drive the transparent paper 9 to overlap with the pull wire 3 and move synchronously.

[0043] By making the transparent paper 9 and the draw string 3 overlap and realize synchronous movement, the accurate alignment of the packaging material and the draw string 3 is ensured, which helps to improve the quality of the final packaging product.

[0053] refer to Figure 1 and Figure 2 As shown, the wire conveying device further includes a first mounting seat 5 for mounting the roller 2, a second mounting seat 6 for mounting the limiting structure 4, a pull ring 7, an adjusting rod 8 and a screw shaft 12, and a first connecting plate 51 and a second connecting plate 52 are vertically connected to form an L-shaped structure. The first connecting plate 51 is used to mount the roller 2, and the second connecting plate 52 is tightly attached to the second mounting seat 6. One end of the screw shaft 12 is connected to the first connecting plate 51, and the screw shaft 12 is inserted into the connecting hole on the roller 2 to connect the roller 2 to the first connecting plate 51. One end of the adjusting rod 8 is connected to the first mounting seat 5, and the other end is threadedly engaged with the second mounting seat 6. The pull ring 7 is installed at the end of the adjusting rod 8, so that by pushing, pulling, and rotating the pull ring 7, the threaded engagement length of the adjusting rod 8 and the second mounting seat 6 can be changed, thereby adjusting the distance between the first mounting seat 5 and the second mounting seat 6 or the opening and closing angle between the first mounting seat 5 and the second mounting seat 6, so that the operator can perform the winding operation.

[0054] refer to Figure 3 As shown, the packaging machine of the utility model comprises a wire conveying device, a transparent paper conveying device, a first detection device 10, a second detection device 11, a controller and a display screen.

[0056] When the roller 2 rotates to convey the pulling wire 3, the pressure wheel 42 always closely adheres to the roller 2 and makes circular self-rotation motion. When the transparent paper 9 is cut, the transparent paper 9 is prone to shake. The pressure wheel 42 can control the pulling wire 3 in the groove 21, thereby preventing the pulling wire 3 from jumping due to the shaking of the transparent paper 9, and ensuring that the pulling wire and the transparent paper are overlapped and adhered to each other in the correct position.

[0059] Through the description of multiple embodiments of the wire-pulling conveyor and packaging machine of the utility model, it can be seen that the wire-pulling conveyor and packaging machine of the utility model have at least the following advantages:

[0060] The limiting structure provided in the wire conveying device cooperates with the roller with circumferential grooves, which can effectively limit the position of the wire in motion and reduce the wire jumping phenomenon.

[0062] The pull ring and adjustment rod are set to make the adjustment of the device simple and quick, thus improving the convenience and efficiency of operation;

[0063] The first detection device, the second detection device and the controller are integrated in the packaging machine to realize real-time monitoring of the overlapping state of the pull cord and the transparent paper, which helps to quickly identify and indicate abnormal position of the pull cord, thereby improving production efficiency and product quality;
