[0033] Example 1

[0034] The present embodiment provides a limiting structure of a packing machine, as shown in the accompanying drawings, comprising: Figs. 1-3

[0035] ​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.

[0036] The support limit frame 13 rotates relative to the base 11, and the support limit frame 13 and the base 11 are rotatably connected.

[0037] 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.

[0038] A limiting plate 14 is located between the tensioning wheel 12 and the support limiting frame 13. The limiting plate 14 is connected to the tensioning wheel 12, which drives the limiting plate 14 to move to the front side of the channel 111. When the tensioning wheel 12 moves towards the lower toothed plate 112, it also drives the limiting plate 14 downwards. When the support limiting frame 13 moves, it drives the tensioning wheel 12, and the limiting plate 14 moves along with it. 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. The cable tie cannot slide out of the channel 111. By using the limiting plate 14, when the tensioning wheel 12 moves towards the lower toothed plate 112, it achieves pressure and fixation of the cable tie. At this time, the limiting plate 14 forms a front-side limit, preventing the cable tie from sliding out during subsequent tightening, which could lead to packaging failure. The limiting plate 14 can limit the cable tie movement.

[0039] Specifically, as shown in the attached document Figs. 1-3 As shown, the limiting plate 14 and the tensioning wheel 12 are rotatably connected. When the limiting plate 14 abuts against the bottom surface of the channel 111, the tensioning wheel 12 has not yet moved to its position, and the limiting plate 14 rotates to better achieve the limiting effect and prevent the cable tie from slipping out. In addition, the tensioning wheel 12 can also be directly connected and fixed to the limiting plate 14.

[0040] Specifically, as shown in the accompanying drawings, Figs. 1-3 The limiting plate 14 is provided with a rotating shaft portion 141, the rotating shaft portion 141 is embedded into the first cavity 121, and the rotating shaft portion 141 rotates relative to the first cavity 121. The rotating shaft portion 141 is provided, and the rotating effect is better achieved.

[0041] Specifically, as shown in the accompanying drawings, Figs. 1-3 The supporting limiting frame 13 is provided with an extension portion 131, the rotating shaft portion 141 is provided with a through hole, the extension portion 131 extends into the through hole to form the fixing of the rotating shaft portion 141, and the outer edge wall of the extension portion 131 abuts against the inner edge wall of the through hole to form the fixing effect.

[0042] Specifically, as shown in the accompanying drawings, Figs. 1-3 The extension portion 131 is provided with a second cavity 133, and the second cavity 133 accommodates the needle roller bearing 15.

[0043] Specifically, as shown in the accompanying drawings, Figs. 1-3 The base 11 is fixed with a fixing pin 113, the limiting plate 14 is provided with a sliding groove 142, and the fixing pin 113 passes through the sliding groove 142 and slides relative to the sliding groove 142. The fixing pin 113 has the effects of limiting and guiding, so that the rotating of the limiting plate 14 is smoother.

[0044] Specifically, as shown in the accompanying drawings, Figs. 1-3 The sliding groove 142 includes a first sliding channel 1421 and a second sliding channel 1422, and the first sliding channel 1421 is connected with the second sliding channel 1422. The fixing pin 113 can move along the first sliding channel 1421, and the fixing pin 113 can also move along the second sliding channel 1422. The sliding groove 142 is a two-section structure, and is not a straight groove. The structure and length of the sliding groove 142 are limited according to the movement direction and rotating angle of the limiting plate 14.

[0045] Specifically, as shown in the accompanying drawings, Figs. 1-3 The first sliding channel 1421 and the second sliding channel 1422 are inclinedly connected. The inclined connection is better matched with the fixing pin 113.

[0046] Obviously, the above embodiments are only examples for clearly illustrating, and are not intended to limit the implementation. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the implementation is not required and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
