The positioning slide rod is mounted on the top of the printing plate via an L-shaped mounting bracket. The positioning baffle is equipped with a second positioning plate that is at the same level as the first positioning plate. A spring is sleeved on the positioning slide rod and connected to the top surface of the L-shaped connecting rod and the inner top surface of the L-shaped mounting bracket.
[0008] Furthermore, the limiting mechanism includes a bidirectional lead screw and a guide rod, and a limiting plate that slides on the bidirectional lead screw and the guide rod via a slider. The back ends of both ends of the limiting plate are connected to the printing press body via telescopic rods. The bidirectional lead screw and the guide rod are mounted on the printing press body via a mounting base, and a motor that is driven and connected to the bidirectional lead screw is mounted on the mounting base.
[0009] Furthermore, the conveyor belt is mounted on the printing press body via a transmission roller, and a second motor connected to the transmission roller is mounted at one end of the printing press body.
[0010] Furthermore, the first positioning plate and the second positioning plate elastically abut against the top two ends of the packaging box.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1) This utility model uses a motor to drive a bidirectional lead screw to adjust the distance between two limiting plates, which facilitates the adjustment of the position of the packaging box and the limiting transmission of packaging boxes of different sizes, thus ensuring printing efficiency.
[0013] 2) The first positioning plate and positioning baffle on both sides of the printing plate move downward and elastically abut against the packaging box under the action of the spring.

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0022] Please refer to Figures 1-4. This utility model provides the following technical solution: a packaging box printing positioning mechanism, including a printing machine body 1, a conveyor belt 3 installed on the printing machine body 1, a limiting mechanism 5 for limiting and transmitting packaging boxes installed on the printing machine body 1, an electric telescopic rod 6 installed on the printing machine body 1 through a connecting bracket 11, a printing plate 7 installed at the bottom telescopic drive end of the electric telescopic rod 6, and positioning structures 8 that position the packaging box are installed on both sides of the printing plate 7.
[0023] Specifically, the positioning structure 8 includes a first positioning plate 81, a positioning baffle 82, and a second positioning plate 87. The tops of the first positioning plate 81 and the positioning baffle 82 are slidably mounted on the positioning slide rod 84 on the top of the printing plate 7 via an L-shaped connecting rod 83. The positioning slide rod 84 is mounted on the top of the printing plate 7 via an L-shaped mounting bracket 85. The positioning baffle 82 is equipped with a second positioning plate 87 that is at the same level as the first positioning plate 81. A spring 86 is sleeved on the positioning slide rod 84 and connects to the top surface of the L-shaped connecting rod 83 and the inner top surface of the L-shaped mounting bracket 85. During printing, the operator activates the electric telescopic rod 6, at which time the printing plate 7 moves downward. When the printing plate 7 moves downward, the first positioning plate 81 and the positioning baffle 82 on both sides move downward simultaneously. The second positioning plate 87 on the first positioning plate 81 and the positioning baffle 82 elastically abuts against the packaging box, and together with the positioning baffle 82, it plays a positioning role for the packaging box, preventing the packaging box from moving and improving the printing quality of the packaging box.
[0024] Specifically, the limiting mechanism 5 includes a bidirectional lead screw 51 and a guide rod 52, and a limiting plate 55 that slides on the bidirectional lead screw 51 and the guide rod 52 via a slider 54. The back ends of the limiting plate 55 are connected to the printing machine body 1 via telescopic rods 56. The bidirectional lead screw 51 and the guide rod 52 are mounted on the printing machine body 1 via a mounting base 53. A motor 57 connected to the bidirectional lead screw 51 is mounted on the mounting base 53. During movement, the motor 57 drives the bidirectional lead screw 51 to move via the slider 54 and the limiting plate 55 to adjust the distance between the two limiting plates 55. The limiting plate 55 facilitates the adjustment of the position of the packaging box, allowing the packaging box to reach the bottom of the printing plate 7 for printing along the conveyor belt 3 under the adjustment of the two limiting plates 55. This facilitates the limiting and transmission of packaging boxes of different sizes, ensuring printing efficiency.
[0025] Specifically, the conveyor belt 3 is mounted on the printing machine body 1 via the transfer roller 2, and a motor 4 connected to the transfer roller 2 is installed at one end of the printing machine body 1; starting the motor 4 drives the transfer roller 2 to move the packaging boxes on it via the conveyor belt 3.
[0026] In addition, the printing press body 1 is equipped with a battery for supplying power to the electric telescopic rod 6, motor 57 and motor 4.
[0027] Specifically, the first positioning plate 81 and the second positioning plate 87 elastically abut against the top two ends of the packaging box.
[0028] The working principle and usage process of this utility model are as follows: When using this utility model, the operator first places the packaging box on the conveyor belt 3, and starts the second motor 4 to drive the transmission roller 2 to move the packaging box on the conveyor belt 3. During the movement, the first motor 57 drives the bidirectional lead screw 51 to move the limiting plate 55 through the slider 54, thereby adjusting the distance between the two limiting plates 55. The limiting plates 55 also facilitate the adjustment of the position of the packaging box, so that the packaging box moves along the conveyor belt 3 to the bottom of the printing plate 7 for printing under the adjustment of the two limiting plates 55. This facilitates the limiting and transmission of packaging boxes of different sizes and ensures printing efficiency.
[0029] During printing, the staff activates the electric telescopic rod 6, at which point the printing plate 7 moves downward. As the printing plate 7 moves downward, the first positioning plate 81 and the positioning baffle 82 on both sides move downward simultaneously through the L-shaped connecting rod 83. The second positioning plate 87 on the first positioning plate 81 and the positioning baffle 82 elastically abuts against the packaging box under the action of the spring 86, and together with the positioning baffle 82, it plays a positioning role for the packaging box, preventing the packaging box from moving and improving the printing quality of the packaging box.
[0030] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
