On the side of the rotating plate one 79 away from the lifting plate 6, a rotating plate two 710 is rotatably connected. The outer side of the rotating plate two 710 is rotatably connected to the inner side of the moving plate 71 through a hinge.

[0023] As a technical optimization scheme of the present utility model, by setting the closing mechanism 7, the opened and closed cartons can be closed, avoiding the loosening of the cartons during the guiding process, and improving the guiding effect of the cartons.

[0024] Reference Figure 1 , on the top of the U-shaped plate 3, a weight reduction groove 8 is opened. The number of the weight reduction grooves 8 is several, and several weight reduction grooves 8 are distributed at equal intervals.

[0025] As a technical optimization scheme of the present utility model, by setting the weight reduction groove 8, the weight of the U-shaped plate 3 can be reduced, avoiding the excessive weight of the U-shaped plate 3 and the conveying device 1, which makes it difficult for the conveying device 1 and the U-shaped plate 3 to move, and improving the moving convenience of the U-shaped plate 3.

[0026] Reference Figure 3 , on both sides inside the lifting plate 6, vertical rods 9 are slidably connected. On the surface of the vertical rods 9, the inside of the U-shaped plate 3 is fixedly connected.

[0027] As a technical optimization scheme of the present utility model, by setting the vertical rods 9, the lifting plate 6 can be slid stably, avoiding the shaking of the lifting plate 6 during the sliding movement, which causes the lifting plate 6 to loosen, and improving the sliding stability of the lifting plate 6.

[0028] Reference Figure 2 , on the top and bottom of the inner wall of the mounting plate 74, limit strips 10 are fixedly connected. The surface of the limit strips 10 is in contact with the surface of the rack 77.

[0029] As a technical optimization scheme of the present utility model, by setting the limit strips 10, the limit strips 10 can be slid stably, avoiding the shaking of the rack 77 during the sliding movement, which causes the rack 77 to loosen, and improving the sliding stability of the rack 77.

[0030] Reference Figure 2, a limit sleeve 11 is sleeved on the right side of the surface of the rack 77, and the surface of the limit sleeve 11 is fixedly connected to the surface of the lifting plate 6.

[0031] As a technical optimization scheme of the present utility model, by providing the limit sleeve 11, the rack 77 can be stably slid for a second time, avoiding the shaking of the rack 77 during the sliding movement, resulting in the loosening of the rack 77, and improving the safety of the rack 77 during sliding use.

[0032] Reference Figure 4 , a reinforcing rib 12 is fixedly connected to the surface of the transmission block 76, and the surface of the reinforcing rib 12 is fixedly connected to the surface of the electric cylinder 75.

[0033] As a technical optimization scheme of the present utility model, by providing the reinforcing rib 12, the connection between the transmission block 76 and the electric cylinder 75 can be strengthened, avoiding the fracture of the transmission block 76 and the electric cylinder 75 during use, preventing the transmission block 76 and the electric cylinder 75 from being unable to cooperate, and improving the use effect of the transmission block 76 and the electric cylinder 75.

[0034] The working principle and usage process of the present utility model: When in use, when the box placed on the top of the conveying device 1 tilts up, the tilted box will be detected by the detection device 2. After being determined to tilt up by the computer, the computer starts the motor 4. The motor 4 drives the screw rod 5 to rotate. The screw rod 5 drives the lifting plate 6 and the pushing roller 73 to be adjusted to a position higher than the top of the box. Then, the electric cylinder 75 is started. The electric cylinder 75 drives the rack 77 to move. The rack 77 drives the gear 78 to rotate. The gear 78 drives the rotating plate one 79 and the rotating plate two 710 to rotate. The rotating plate two 710 drives the moving plate 71 and the sliding rod 72 to move towards the side close to the box. The sliding rod 72 drives the pushing roller 73 to move towards the side close to the box. When the pushing roller 73 contacts the tilted part of the box, the tilted part is pushed flat, thus having the advantages of safe and non-destructive guiding and closing.

[0035] In summary: For the guiding mechanism of this strapping machine, through the combined use of the conveying device 1, the detection device 2, the U-shaped plate 3, the motor 4, the screw rod 5, the lifting plate 6 and the closing mechanism 7, it solves the problem that the movement track of the movable pressing plate is in a rotating manner. During the rotation of the movable pressing plate, it moves from top to bottom. During the downward flipping of the movable pressing plate, it is impossible to flatten the box in a tilted contact vertical state, and even may damage the vertically tilted box body, resulting in the box being unusable and reducing the guiding efficiency and closing effect of the box.
