In order to solve the technical problems, the invention adopts the following technical scheme: the paperboard forming device comprises a power unit, a base, a transmission part and an adsorption part, wherein the power unit and the transmission part are both arranged on the base, the adsorption part is arranged on the transmission part, the transmission part comprises a transmission rod and a double-rocker assembly, the double-rocker assembly on the transmission part is symmetrically distributed, the transmission rod is movably arranged on the base in a linear sliding mode, one end of the transmission rod is connected with the power unit, the other end of the transmission rod is connected with the double-rocker assembly, the adsorption part is arranged at the end part of a rocker of the double-rocker assembly, the adsorption part is symmetrically distributed on the base, and the double-rocker assembly drives the adsorption part to swing and move within a range distributed on two sides of the base.

The design idea of the invention is to simulate the bending operation of a human hand based on a connecting rod structure. The adsorption part is communicated with the vacuum pipeline and then can establish a connection relation with the paperboard in an adsorption mode; the double-rocker assembly in the transmission component drives the adsorption component to move, and the spatial posture of the adsorption component can be changed in a swinging mode in the moving process of the adsorption component, so that the operation surface of the adsorption component can enter a horizontal plane and a vertical plane. The change of the operation surface of the adsorption part completely corresponds to the initial state and the forming state of the paper board, namely the transmission part simulates the bending operation of a human hand in the process of controlling the motion of the adsorption part. The board forming device can thereby perform the operation of unfolding the board. The paperboard forming device is combined on the joint robot, so that the automatic workpiece taking, bending and boxing operations are realized, and the automation degree of the production line can be improved.

The power unit can be selected from an air cylinder, an oil cylinder, an electric cylinder and a swing arm structure based on a motor, the service object of the power unit is a transmission rod, the transmission rod is driven to move linearly, and the transmission rod can obtain the characteristic of limiting and guiding action from a base to keep moving linearly, so that the power provided by the power unit can be the power with the direction coincident with the moving direction of the transmission rod or the power capable of providing component force in the moving direction of the transmission rod. The adsorption part adopts a sucker as the best, and can generate a negative pressure condition immediately after the negative pressure pipeline is connected, so that the connection relation with the paperboard is quickly established.

The paperboard forming device can optimize the number of the structural components, namely the distribution, according to the width of the paperboard, so that when the width of the paperboard is larger, the corresponding width of the adsorption component is larger, and the transmission components required for driving the adsorption component are increased in a reasonable range and reasonably arranged, therefore, two groups of transmission components can be arranged on the base and are distributed on two sides of the power unit.

The design can obtain the characteristics of compact structure, simplicity and lightness to the maximum extent. In order to obtain a more compact structure, the invention is further optimized from the transmission structure in the double-rocker assembly, specifically, the double-rocker assembly comprises a long rocker, a short rocker and a push-pull rod, the length of the long rocker is greater than that of the short rocker, one end of the long rocker is connected with the base, the other end of the long rocker is connected with the adsorption component, one end of the short rocker is connected with the base, the other end of the short rocker is connected with the adsorption component, the distance from the connecting part of the long rocker and the base to the base is smaller than that from the connecting part of the short rocker and the base to the base, one end of the push-pull rod is connected with the transmission rod, the other end of the push-pull rod is connected with the short rocker, the connecting part of the push-pull rod and the short rocker is located in the middle area of the short rocker, and the distance from the connecting part of the long rocker and the base to the connecting part of the long rocker and the adsorption component is greater than that from the connecting part of the long rocker and the base to the connecting part of the short rocker and the base The distance between the connecting part of the long rocker and the base and the connecting part of the short rocker and the base is greater than the distance between the connecting part of the short rocker and the base and the connecting part of the short rocker and the adsorption component, and the distance between the connecting part of the short rocker and the base and the connecting part of the short rocker and the adsorption component is greater than the distance between the connecting part of the short rocker and the base and the connecting part of the long rocker and the base.

The power transmission process from the power unit to the adsorption part needs to ensure that each group of double-rocker assemblies can synchronously move, which is a core factor for ensuring the synchronous action of the adsorption part and a technical guarantee for maintaining the paperboard to be bent in place.

In order to further ensure that the motion processes of the transmission rod are in the same linear direction, the base is provided with a guide through hole, the extension direction of the guide through hole is parallel to the linear motion direction of the transmission rod, and a rotating shaft connected with the push-pull rod extends into the guide through hole.

The cardboard needs to be placed into a packaging box after being unfolded, the packaging box has a specific orientation posture under the influence of the opening operation of the packaging box, and particularly, the flat posture of the packaging box shows remarkable orientation when the packaging box is in a flat cuboid shape. The unfolded sheet must be placed in the box at an angle that will accommodate the box, i.e., the mating angle between the sheet and the box must be correct.
