[0034] Embodiment 1

[0035] This embodiment provides a limiting structure for a packing machine, as shown in the attached figure. Figures 1-3 As shown, it includes:

[0036] The base 11 has a channel 111, which has openings on its front, left, and right sides. Cable ties enter the channel 111 from the front side; this is existing technology and will not be described in detail in this embodiment. A lower toothed plate 112 is fixed to the bottom surface of the channel 111. The lower toothed plate 112 specifically cooperates with the tightening wheel 12 to tighten and weld the cable ties, thereby achieving a secure packaging effect.

[0037] The support limit frame 13 rotates relative to the base 11, and the support limit frame 13 and the base 11 are rotatably connected.

[0038] The tensioning wheel 12 moves relative to the base 11. Here, the tensioning wheel 12 can rotate relative to the base 11, and it can also float up and down, left and right. This tensioning wheel 12 can be implemented using other transmission structures. The transmission structure cooperating with the tensioning wheel 12 is existing technology, and the working principle of the tensioning wheel 12 is also existing technology. This embodiment mainly describes how to prevent the cable tie from slipping out of the channel 111, so the detailed description of how the tensioning wheel 12 moves is not elaborated. When the support limiting frame 13 moves, it drives the tensioning wheel 12 to move towards the lower toothed plate 112. When the support limiting frame 13 rotates, it drives the tensioning wheel 12 to move towards the lower toothed plate 112, that is, the tensioning wheel 12 moves downwards. The tensioning wheel 12 cooperates with the lower toothed plate 112 to tighten and weld the cable tie, thereby achieving the effect of securing the cable tie.

[0039] A limiting plate 14 is connected to a support limiting frame 13. When the support limiting frame 13 rotates, it drives the limiting plate 14 to move. The limiting plate 14 moves to the front side of the channel 111, preventing the cable tie from sliding out of the channel 111, thus creating a limiting and blocking effect. At this time, the cable tie cannot slide out of the channel 111. With the setting of the limiting plate 14, when the tightening wheel 12 moves towards the lower toothed plate 112, the cable tie is pressed and fixed. At this time, the limiting plate 14 forms a front limiting to prevent the cable tie from sliding out during subsequent tightening, which would lead to packaging failure. The limiting plate 14 can limit the cable tie.

[0040] Specifically, as shown in the attached document Figures 1-3 As shown, it also includes a rotating pin 16, which passes through the limiting plate 14 and connects to the support limiting frame 13. The limiting plate 14 rotates around the rotating pin 16. The rotating pin 16 facilitates the connection and fixation between the limiting plate 14 and the support limiting frame 13. Alternatively, the rotation effect can also be achieved through the cooperation of a rotating shaft and a rotating shaft hole.

[0041] Specifically, as shown in the attached document Figures 1-3 As shown, the limiting plate 14 is rotatably connected to the supporting limiting frame 13. The limiting plate 14 rotates relative to the supporting limiting frame 13, and the supporting limiting frame 13 drives the limiting plate 14 to move to the front side of the channel 111. That is, the supporting limiting frame 13 can drive the limiting plate 14 to move, and the limiting plate 14 can also rotate relative to the supporting limiting frame 13. When the supporting limiting frame 13 moves towards the lower toothed plate 112, it drives the limiting plate 14 to move downward as well. When the limiting plate 14 abuts against the bottom surface of the channel 111, the supporting limiting frame 13 has not yet moved to its final position, and the limiting plate 14 rotates, thus better achieving the limiting effect and preventing the cable tie from slipping out. In addition, the limiting plate 14 and the supporting limiting frame 13 can also be directly connected and fixed.

[0042] Specifically, as shown in the attached document Figures 1-3 As shown, the limiting plate 14 is located on the front side of the supporting limiting frame 13, and the limiting plate 14 and the supporting limiting frame 13 are rotatably connected by the rotating pin 16.

[0043] Specifically, as shown in the attached document Figures 1-3 As shown, the tensioning wheel 12 has a first chamber 121, and the support and limiting frame 13 has an extension 131 that extends into the first chamber 121. It should be noted that there is a gap between the outer wall of the extension 131 and the inner wall of the first chamber 121, allowing them to move relative to each other, such as rotating relative to each other or sliding relative to each other downwards. However, when the support and limiting frame 13 moves, it also drives the tensioning wheel 12 to move.

[0044] Specifically, as shown in the attached document Figures 1-3 As shown, the extension 131 is provided with a second chamber 133, which houses the needle roller bearing 15.

[0045] Specifically, as shown in the attached document Figures 1-3 As shown, the base 11 is fixed with a fixing pin 113, and the limiting plate 14 is provided with a sliding groove 142. The fixing pin 113 passes through the sliding groove 142 and slides relative to the sliding groove 142. The fixing pin 113 serves to limit and guide, making the rotation of the limiting plate 14 smoother. The sliding groove 142 is a two-section structure, not a straight groove. The structure and length of the sliding groove 142 are limited according to the movement direction and rotation angle of the limiting plate 14.

[0046] Specifically, as shown in the attached document Figures 1-3 As shown, the slide 142 includes a first slide 1421 and a second slide 1422, which are connected. The fixing pin 113 can move along the first slide 1421 and the second slide 1422. The slide 142 is a two-section structure and is not a straight groove. The structure and length of the slide 142 are limited according to the movement direction and rotation angle of the limiting plate 14.

[0047] Specifically, as shown in the attached document Figures 1-3 As shown, the first slide rail 1421 and the second slide rail 1422 are connected at an angle. This angled connection allows for better engagement with the fixing pin 113.

[0048] Specifically, as shown in the attached document Figures 1-3 As shown, the limiting plate 14 is provided with a reinforcing part 143, and a sliding groove 142 is disposed on the reinforcing part 143. The reinforcing part 143 increases the strength of the limiting plate 14. Specifically, the reinforcing part 143 means that the thickness of the location of the sliding groove 142 is greater than the thickness of the other locations of the limiting plate 14. For example, the thickness of the area where the sliding groove 142 is located is greater than the thickness of the area where the limiting plate 14 connects with the support limiting frame.

[0049] Specifically, as shown in the attached document Figures 1-3 As shown, the support and limiting frame 13 is provided with a limiting groove 132, and the sidewall of the limiting groove 132 is located on the rotation trajectory of the limiting plate 14. The setting of the limiting groove 132 forms a limiting effect to prevent the limiting plate 14 from rotating excessively.

[0050] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
