After the paper box 5 to be folded passes, the photoelectric switch is reset to wait for the next action process. The structure is simple, easy to use, convenient for continuous use, and effectively prevents transitional bending guide forming.

[0024] A telescopic rod 203 is installed at the lower end of the electric cylinder 2, and the lower end of the telescopic rod 203 is fixedly connected to the electric suction cup 201. A ventilation valve is arranged inside the electric suction cup 201, and the electric suction cup 201 is switched on and off by the ventilation valve to facilitate the fixing work.

[0025] A reduction motor 103 is installed at the front end of the support frame 101, and the reduction motor 103 is fixedly connected to the support frame 101. The motor shaft of the reduction motor 103 is fixedly connected to the turntable 1 through a coupling. A positioning shaft 202 runs through the upper end of the electric cylinder 2. The positioning shaft 202 passes through the turntable 1 and is rotatably connected to the turntable 1 through a bearing. An electric motor 102 is installed at the rear end of the turntable 1. The motor 102 and the positioning shaft 202 are fixedly connected through a coupling. The turntable 1 is driven to rotate by the reduction motor 103. The turntable 1 and the motor 102 drag the electric cylinder 2 to move, which is sucked by the electric suction cup 201 and rotated to adjust the overall position of the electric cylinder 2. The structure is simple and easy to use.

[0026] Specifically, the paper box 5 to be folded is cut by the transition forming mechanism to cut out the first paper box folding cover 501 and the second paper box folding cover 502, which are placed on the placement rack, and a photoelectric switch is installed at a reasonable position. Before the paper box 5 to be folded is formed, the photoelectric detection is performed to send out an electric signal to control the output of the reversing valve, and the turntable 1 is driven to rotate by the reduction motor 103. The turntable 1 and the motor 102 drag the electric cylinder 2 to move, and the electric suction cup 201 is used to suck and rotate the overall position of the electric cylinder 2 to place the paper box 5 to be folded above the conveyor belt 3, and then the electric suction cup 201 is used to suck and rotate the electric cylinder 2 to adjust the overall position of the electric cylinder 2.

After the paper box 5 to be folded passes, the photoelectric switch is reset to wait for the next action process. It has a simple structure, is easy to use, and is convenient for continuous use. It can effectively prevent transitional bending and guiding molding. As consumers' demand for product quality increases, ordinary cardboard coated paper boxes are replaced with corrugated paper boxes, which makes transitional bending and molding difficult. In actual production, paper boxes are jammed more seriously, molding is difficult, and the production speed is limited and the expected output cannot be achieved.

[0027] In order to solve the technical problems of complex structure and instability of automatic cartoning machines in the prior art, please refer to Figure 1 - Figure 3 , providing the following technical solutions:

[0028] A support frame 101 is installed at the rear end of the turntable 1 , a fixing frame 401 is welded to the lower part of the support frame 101 , and the fixing frame 401 is fixedly connected to the auxiliary pressing plate 4 .

[0029] A connecting roller 301 is installed inside the conveyor belt 3, and a card slot is set between the connecting rollers 301. Transmission gears are installed at both ends of the conveyor belt 3. The conveyor belt 3 is driven to move by the transmission gears, and is electrically controlled and automatically moved. A limiting frame 302 is installed above the conveyor belt 3. The limiting frame 302 is used to fix the paper box 5 to be folded. An integral buffer frame 402 is set at one end of the auxiliary pressing plate 4. The buffer frame 402 is used to push the position of the paper box 5 to be folded. The upper and lower ends of the paper box 5 to be folded are both provided with a first paper box folding cover 501, and both sides of the paper box 5 to be folded are both provided with a second paper box folding cover 502. During the movement of the conveyor belt 3, the paper box 5 to be folded inside the limiting frame 302 is moved. After moving to the bottom of the auxiliary pressing plate 4, the buffer frame 402 is used to limit and pressurize it, so that the paper box 5 to be folded can be folded and formed, which assists the work and improves the work effect.

[0030] Specifically, an auxiliary pressure plate 4 is arranged above the conveyor belt 3. When the conveyor belt 3 moves, the paper box 5 to be folded inside the limiting frame 302 is moved. After it moves to below the auxiliary pressure plate 4, the buffer frame 402 is used to limit and pressurize it, so that the paper box 5 to be folded can be folded and formed, which assists the work and improves the working effect.

[0031] Working principle: When in use, the paper box 5 to be folded is cut through the transition forming mechanism, and the first paper box folding cover 501 and the second paper box folding cover 502 are cut out and placed on the placement rack. A photoelectric switch is installed at a reasonable position. Before the paper box 5 to be folded is formed, the photoelectric detection is performed to send out an electrical signal to control the output of the reversing valve, and the turntable 1 is driven to rotate by the reduction motor 103. The turntable 1 and the motor 102 drag the electric cylinder 2 to move, and the electric suction cup 201 is used to suck and rotate the overall position of the electric cylinder 2 to place the paper box 5 to be folded above the conveyor belt 3, and then the telescopic rod 203 of the electric cylinder 2 is extended to press the paper box 5 to be folded as a whole to between the limit racks 302, and an auxiliary pressing plate 4 is set above the conveyor belt 3. During the movement of the conveyor belt 3, the paper box 5 to be folded inside the limit frame 302 is moved. After moving to the bottom of the auxiliary pressure plate 4, the buffer frame 402 is used to limit and pressurize, so that the paper box 5 to be folded can be folded and formed, and the auxiliary work is improved. The working effect is avoided, and the excessive friction of the paper box displacement may cause the paper box to be jammed. After the paper box 5 to be folded passes, the photoelectric switch is reset and waits for the next action process. The structure is simple, easy to use, and convenient for continuous use. It effectively prevents transitional bending and guiding forming. As consumers' demand for product quality increases, ordinary cardboard coated paper boxes are replaced with corrugated paper boxes, which makes transitional bending and forming difficult. In actual production, the paper box is jammed more seriously, forming is difficult, and the production speed is limited and the expected output cannot be achieved.
