The mechanism 5 includes a motor 501, a screw rod 502, a moving ring 503, a connecting rod 504 and a gluing head 505. The workbench 4 is provided with a screw rod 502 near the gluing groove 404. The bottom end of the screw rod 502 is provided with a motor 501. The screw rod 502 is provided with a moving ring 503. A connecting rod 504 is provided between two adjacent moving rings 503. The moving ring 503 is provided with a gluing head 505 near the gluing groove 404. The moving ring 503 is connected to the screw rod 502 by a nut. The notch size of the shaping groove 401 is consistent with the middle size of the cross-shaped cardboard 1. The micro conveyor belt 402 is vertically arranged to the top of the workbench 4.

[0022] According to the above embodiment, it should be noted that: a camera is provided at the bottom end of the top plate 6. When in use, the cross-shaped cardboard 1 is placed on the first conveyor belt 2. When the cross-shaped cardboard 1 moves to the bottom end of the first telescopic cylinder 601, the camera sends the captured image information to the controller. The controller receives and processes the information and sends the processed electrical signal to the first telescopic cylinder 601. The first telescopic cylinder 601 starts to drive the pressing plate 603 at that location to press down, leaving a mark on the cross-shaped cardboard to facilitate subsequent folding.

[0023] When the cross-shaped paperboard 1 with the indentation is moved onto the workbench 4, the micro conveyor belt 402 rotates, and the sawtooth bar 403 grabs the bottom end of the cross-shaped paperboard 1, so that it can move and increase the friction with the workbench 4.

[0024] When the cross-shaped cardboard 1 is aligned with the shaping groove 401, the second telescopic cylinder 602 starts to drive the pressing plate 603 to press down, so that the cross-shaped cardboard 1 is pressed into the shaping groove 401, and the motor 501 starts to drive the screw rod 502 to rotate. At this time, the moving ring 503 moves on the screw rod 502, and the glue coating head 505 is aligned with the coating groove 505 position to apply coating to the connection of the cross-shaped carton 1.

[0025] A hydraulic cylinder is provided at the bottom of the shaping groove 401. After the coating is completed, the cross-shaped carton 1 will move up driven by the hydraulic cylinder and move out of the shaping groove 401. At this time, it is manually moved to the position of the second conveyor belt 3, and the folded and shaped carton is moved out.

[0026] See also Figure 1-3 As shown, an automatic folding device for carton boxes includes the first conveyor belt 2 and the top of the workbench 4 is provided with a top plate 6, the bottom of the top plate 6 is provided with a first telescopic cylinder 601 near the first conveyor belt 2, the bottom of the top plate 6 is provided with a second telescopic cylinder 602 near the shaping groove 401, the execution ends of the first telescopic cylinder 601 and the second telescopic cylinder 602 are both connected with a pressing plate 603, the pressing plate 603 is arranged in a hollow rectangular shape, the pressing plate 603 is consistent in size with the shaping groove 401, and the second conveyor belt 3 is provided at the end of the workbench 4 away from the first conveyor belt 2.

[0027] According to the above embodiment, it should be noted that: the pressing plate 603 of the first telescopic cylinder 601 realizes indentation, and the execution end of the second telescopic cylinder 602 presses deeper than the execution end of the first telescopic cylinder 601, so the pressing plate 603 of the second telescopic cylinder 602 can press the cross-shaped paperboard 1 into the shaping groove 401.

[0028] In summary, the use process of the device is as follows: a camera is provided at the bottom of the top plate 6. When in use, the cross-shaped cardboard 1 is placed on the first conveyor belt 2. When the cross-shaped cardboard 1 moves to the bottom of the first telescopic cylinder 601, the camera sends the captured image information to the controller. After receiving and processing, the controller sends the processed electrical signal to the first telescopic cylinder 601. The first telescopic cylinder 601 starts to drive the pressure plate 603 at that location to press down, leaving a mark on the cross-shaped cardboard to facilitate subsequent folding.

[0029] When the cross-shaped paperboard 1 with the indentation is moved onto the workbench 4, the micro conveyor belt 402 rotates, and the sawtooth bar 403 grabs the bottom end of the cross-shaped paperboard 1, so that it can move and increase the friction with the workbench 4.

[0030] When the cross-shaped cardboard 1 is aligned with the shaping groove 401, the second telescopic cylinder 602 starts to drive the pressing plate 603 to press down, so that the cross-shaped cardboard 1 is pressed into the shaping groove 401, and the motor 501 starts to drive the screw rod 502 to rotate. At this time, the moving ring 503 moves on the screw rod 502, and the glue coating head 505 is aligned with the coating groove 505 position to apply coating to the connection of the cross-shaped carton 1.

[0031] A hydraulic cylinder is provided at the bottom of the shaping groove 401. After the coating is completed, the cross-shaped carton 1 will move up driven by the hydraulic cylinder and move out of the shaping groove 401. At this time, it is manually moved to the position of the second conveyor belt 3, and the folded and shaped carton is moved out.
