[0042] See also Figures 1-2 Preferably, a limit slider 13 is fixedly connected to the V-shaped plate 10, and the limit slider 13 is slidably matched with the limit slider 9 fixedly connected to the bracket 2. The purpose of this arrangement is to limit the V-shaped plate 10, so that the V-shaped plate 10 is prevented from tilting due to its own weight and the weight of the carton during movement, causing the carton to deflect when unfolded, thereby affecting the gluing of the carton by the folding mechanism 5.

[0043] Preferably, the transmission pair A is any one of a pulley pair, a sprocket pair and a gear pair.

[0044] Preferably, the elastic member is any one of a spring, a compression spring and an elastic steel plate.

[0045] In the embodiment of the present invention, the linear moving part 12 performs linear motion towards each other by pulling the two V-shaped plates 10. The two V-shaped plates 10 squeeze the carton to cause the carton to expand and press against the other two V-shaped plates 10. At the same time, two groups of pushing blocks 15 of different heights push the two combined plates at one end of the carton to tilt at different angles under the push of the elastic member. At this time, the motor A6 drives the screw rod A7 to rotate in the horizontal direction through the transmission pair A.

The tape roll is rotationally connected to a column 25 fixedly connected to the slider B24.

[0048] Preferably, the transmission pair B is any one of a pulley pair, a sprocket pair and a gear pair.

[0049] Preferably, the tape roll is formed by winding multiple sections of tape.

[0050] Preferably, the slider A19 is slidably matched with a T-shaped slide fixedly connected to the base 1. The purpose of this arrangement is to use the T-shaped slide to limit the slider A19 and prevent the slider A19 from deviating and causing the screw plate 18 to get stuck.

[0051] In the embodiment of the present invention, the screw A7 pushes the screw plate 18 to perform linear motion in the horizontal direction along the base 1, and the screw plate 18 drives the slider A19 to perform synchronous motion. The slider A19 pushes the box body 21 to perform linear motion to get close to the carton through the support rod 20.
