A rotating handle 205 is provided on the rotating disk 203.

[0026] In the technical solution of this utility model, the limiting mechanism can be installed inside the packaging box sealing device through the mounting plate 1. By controlling the operation of the electric telescopic rod 5, the position of the baffle 6 can be quickly adjusted. The baffle 6 directly contacts the packaging box, ensuring that the packaging box can be stably and accurately stopped at the sealing position. By turning the handle 205, the rotating disk 203 and the lead screw 202 can be rotated, which in turn moves the adjusting block 204 and the electric telescopic rod 5, allowing the horizontal position of the electric telescopic rod 5 to be adjusted. It can be quickly adjusted according to packaging boxes of different sizes, and can easily adapt to packaging boxes of different sizes and shapes, improving the flexibility of the production line. It can effectively solve the problems of complex structure, inflexible adjustment and high cost of traditional sealing devices.

[0031] like Figure 1 and Figure 2 As shown, both the connecting plate 4 and the electric telescopic rod 5 are inclined; the design of the inclined angle reduces interference between mechanical parts and improves the working efficiency of the entire device.

[0032] The adjustment frame 201 is provided with a first scale plate 14, and the adjustment plate 11 is provided with a second scale plate 15. The first scale plate 14 is located on the adjustment frame 201 and is used to help the operator quickly understand the specific degree of adjustment, so as to make the adjustment more accurate. The second scale plate 15 is located on the adjustment plate 11 and provides additional reference to ensure that the operator can clearly know the adjustment range when adjusting the position of the positioning plate 9.

[0033] Working Principle: The limiting mechanism can be installed inside the packaging box sealing device via the mounting plate 1. By controlling the operation of the electric telescopic rod 5, the position of the baffle 6 can be quickly adjusted. The baffle 6 directly contacts the packaging box, ensuring that the packaging box can be stably and accurately stopped at the sealing position. By turning the handle 205, the rotating disk 203 and the lead screw 202 can be rotated, which in turn moves the adjusting block 204 and the electric telescopic rod 5, allowing the horizontal position of the electric telescopic rod 5 to be adjusted quickly according to different sizes of packaging boxes. It can easily adapt to packaging boxes of different sizes and shapes, improving the flexibility of the production line. It can effectively solve the problems of complex structure, inflexible adjustment, and high cost of traditional sealing devices. Through the electric telescopic rod 5 and the precise adjustment mechanism, the packaging box can be positioned quickly and accurately on the production line, thereby ensuring the accuracy and efficiency of the sealing process.
