Description

Paperboard overturning mechanism

Technical Field

The utility model relates to the field of paperboard production equipment, in particular to a paperboard overturning mechanism.

Background

The packaging needs to be packaged by using a packaging box, the packaging box is formed by folding a packaging paper board, the packaging paper board is cut into a required size, then printing, grooving and nailing are carried out on the packaging paper board, and the final packaging paper board is formed through a series of operations. After the paper board is manufactured, two sides are arranged, one side is smooth and provided with patterns, the other side is rough, the paper boards are required to be stacked together, if all the paper boards are stacked sequentially according to one side in the stacking process, the slipping phenomenon is easy to occur between the stacked paper boards, so that after one side of a plurality of paper boards is stacked, the other sides of the other paper boards are turned over to be stacked, and the stacking is stable. And the stacking mode is that the front face is upward or the back face is upward. Therefore, when the paperboards are used in the later period, the workers are required to count one by one according to the number of the paperboards, time is wasted, and the number of the paperboards can be rapidly determined only by stacking the paperboards in the front and back directions.

The automatic paperboard overturning device is characterized in that all the paperboards cannot be stacked, the paperboards are overturned in the stacking process, various paperboard overturning mechanisms are arranged on the market at present through examination, for example, a Chinese utility model with the bulletin number of CN216863056U discloses an automatic paperboard overturning device, the automatic paperboard overturning device comprises a first paperboard conveying structure, a second paperboard conveying structure and a first paperboard conveying structure, the right end of the first paperboard conveying structure is provided with the overturning structure, the lower part of the first paperboard conveying structure is provided with the second paperboard conveying structure, the overturning structure comprises an electric telescopic rod in contact with the ground, an L-shaped frame connected with the electric telescopic rod, a vacuum pump connected with the other end of the L-shaped frame, a rotating pipe movably connected with the other end of the L-shaped frame and an overturning plate connected with the other end of the rotating pipe, an air inlet of the vacuum pump is connected with the rotating pipe through a guide pipe, and through holes are uniformly formed in the top of an inner cavity of the overturning plate. This automatic turning device of cardboard, through the setting of flip structure, when the cardboard is located the upset board, the cooperation of rotation motor and vacuum pump is used, makes the cardboard rotate along with the upset board, and the cardboard can realize overturning fast, and the cardboard atress is even in the upset in-process, can not influence its quality, the production of cardboard of being convenient for.

The defects of the paperboard overturning mechanism are as follows: 1. because the turnover mechanism is arranged between the two sections of conveyor belts, when the turnover mechanism is turned over, each piece of paper to be turned over needs to be started for one time, the energy consumption is high, the motor overload can occur in the assembly line operation, and the service life is shortened; 2. the cardboard can only circulate on the horizontal plane, can't circulate on the vertical height and be inconvenient for subsequent stacking operation, still need other equipment or manual work to raise the cardboard and stack.
