The utility model relates to the technical field of packaging machinery, and discloses a bending device for folding box production, which comprises a support frame packaging machinery, the outside of the support frame packaging machinery is fixedly connected with a support seat packaging machinery, the outside of the support frame packaging machinery is provided with a bending
assembly, and the support seat packaging machinery is provided with a support seat. A pushing
assembly is installed outside the supporting frame
packaging machine. The bending
assembly comprises a fixing plate
packaging machine, the outer portion of the fixing plate
packaging machine is fixedly connected to the outer portion of the supporting frame packaging
machine, and the inner side of the fixing plate packaging
machine is rotationally connected with a connecting plate packaging
machine. According to the
paperboard folding device, the
hydraulic cylinder stretches out and draws back to drive the connecting plate to be folded, meanwhile, the electric push rod drives the folding plate to move, the folding action can be accurately controlled through the
cooperative work mode, and unformed paperboards are folded. By means of the design, the folding accuracy can be guaranteed, and the
automation degree of the folding process is improved.
