The control of the shrinking machine, the function of the indentation plate 12 is to press the cardboard 25, because the position of the indented plate 12 and the supporting plate 13 is opposite, the role of the supporting plate 13 is to hold the cardboard 25, together with the indented plate 12 , the paperboard 25 is clamped up and down, and the pressure line is pressed, and the pressure line part II presses the paper board 25, and at this time, the paper box folding part IV folds the nail box of the paper board 25 to the nail box of the paper board 25, the three steps are The chain 2 works synchronously.

The equipment used includes a chain drive shaft 1, a cardboard conveying block 3, a plurality of cardboard conveying blocks 3, which are fixedly disposed on the chain 2, the robot arm 4 and the positioning baffle 5, and the chain drive shaft 1 has a plurality of rows. The chain 2, the chain 2 for conveying the cardboard 25 is connected with the reversing motor. When the chain 2 advances by a certain distance S1, the forward rotation motor stops, reverses the motor operation, and causes the chain to retreat a short distance S2, and then rest for a period of time T The carton manufacturing method includes a paper feeding portion I, a folding box portion IV, and a nail box bonding box portion VI from the upstream to the downstream, specifically including a chain driving shaft 1, a chain 2, a cardboard conveying block 3, and a robot arm 4.

In this embodiment, the mechanical arm 4 folds the cardboard, and the servo motor 6 and the servo motor 2, the chain drive shaft 1 and the output shaft of the servo motor 6 are connected by a belt, so that the chain drive shaft 1 is provided by a separate servo. The motor is driven by a 6. The robot arm 4 is divided into two types: an operating arm 4a and a driving side arm 4b. The operating side arm 4a and the driving side arm 4b are respectively located on both sides of the frame and connected to the frame through the shaft. The mechanical arm 4 can be freely moved up and down, and the mechanical arm 4a on the operating side and the mechanical arm 4b on the driving side are folded inward to fold the cardboard 25, and the two kinds of mechanical arms 4 are respectively connected with the servo motor 2, servo The motor 2 7 can control the robot arm 4a on the operating side and the robot arm 4b on the driving side, respectively, and the driving speed of the robot arm 4a on the operating side is slightly larger than the driving speed of the robot arm 4b on the driving side, or the arm of the operating side. The driving time of la is slightly earlier than the driving time of the mechanical arm lb on the driving side, so that when folded, it is the arm of the operating side. 4a is lowered first, and the mechanical arm 4b on the driving side is lowered rearward to ensure that one end of the folded cardboard 25 is folded over the other end to meet the needs of the subsequent nail box. Since the chain drive shaft 1 and the mechanical arm 4 are driven by separate servo motors, the current production line is gradually folded by the guide bar and the conveyor belt, and the folding error is large and the precision is poor, and the structure is complicated, so that the whole The cost of the production line is greatly reduced, which is suitable for the installation and use of small and medium enterprises.

Both ends of the robot arm 4 are folded forward so that the robot arm 4 forms an inward space. The mechanical arm 4 may be made of iron or iron, and the shape is not limited, and the mechanical arm 4 in the method has an inward space, so that when the mechanical failure occurs, the cardboard conveying stopper 3 can be inward from the mechanical arm 4. The space passes through or the corresponding portion of the mechanical arm 4 corresponding to the cardboard conveying block 3 is provided with a corresponding groove to prevent the mechanical arm 4 from being damaged.

In order to extend the stroke of the arm 4 when it is folded in or out, a limit stop 8 is attached to one side of the shaft between the arm 4 and the frame to control the stroke of the arm 4.

In use, as shown in Fig. 2, the unfolded cardboard 25 is divided into four parts, namely, a part A, a part B, a part C, and a part D, and the parts A and D are the two ends of the cardboard 25. When the cardboard conveyance stopper 3 is hooked on the cardboard 25 and conveyed to the portion of the folding arm portion IV of the mechanical arm 4, the state at this time is as shown in FIG. 3, and then the robot arm 4a on the operation side and the robot arm 4b on the driving side are in the servo motor. The driving of the two 7 is folded inward, the arm 4a on the operating side is lowered first, and the arm 4b on the driving side is lowered rearward, so that the A portion of the cardboard 25 is folded under the D portion, and the state at this time is as shown in FIG. It is shown that the portions where the A portion and the D portion coincide with each other are used for the nail box or the glue box operation in the subsequent nail box portion.

The step is divided into two sets, which are respectively located on the left and right sides of the frame. On the side, each set includes a cylinder 11 , an indentation plate 12 and a pallet 13 . The lower end of the cylinder 11 is provided with an indentation plate 12 , and the bottom of the indentation plate 12 has a sharp edge; the indentation plate 12 and the pallet 13 respectively Located on the upper and lower sides of the frame, and the position of the indentation plate 12 and the pallet 13 are opposite. The cylinder 11 is driven to rise or fall by the cylinder 11, and the cylinder 11 is controlled by the air compressor. The function of the indentation plate 12 is to press the cardboard 25 due to the position of the indentation plate 12 and the pallet 13. In contrast, the role of the pallet 13 is to hold the cardboard 25, and together with the indentation plate 12, the cardboard 25 is clamped up and down, and the crimping is performed. In order to ensure the accuracy of the position of the indentation plate 12 during each ascending or descending movement, the guide block 14 is installed at both ends of the indentation plate 12, so that the accuracy of the pressing line can be ensured and the quality of the carton can be ensured.
