AI Technical Summary
In traditional carton stapling machines, the short folding mechanism can cause the carton board to shift position during the cardboard bending process, resulting in the short edge failing to bend along the preset crease and affecting the quality of the short fold.
The structure combines a lifting seat with a floating frame. The floating frame is equipped with pressure plate rollers and guide components. The pressure plate rollers first press the long side of the cardboard onto the stop block, and then the short side folding plate is bent. Combined with the use of linear motor drive and elastic components, the cardboard position is ensured to be stable.
It effectively prevents the cardboard from shifting position during the short folding process, ensuring that the short edge is accurately bent along the preset crease, thus improving the quality of the short folding of the cardboard.

TECHNICAL FIELD
[0001] The utility model relates to a box nailing machine, in particular to a short edge folding mechanism of box nailing machine. BACKGROUND
[0002] The box nailing machine is a kind of equipment for realizing the automatic forming and nailing of carton. The carton is generally formed by bending paperboard, and in order to realize the nailing of paperboard after forming, there are some short edge parts on the paperboard, which need to be extruded and bent by short edge folding mechanism during the forming of carton. The traditional short edge folding mechanism mainly adopts a single short edge folding plate structure. The defect of this structure in use is that only the short edge folding plate extrudes the short edge during the edge folding operation, and the carton board is easily offset in position to a certain extent during the extrusion and bending process, which causes the short edge to be unable to be bent along the preset crease, affecting the quality of short edge folding. SUMMARY
[0003] In view of the deficiencies in the background art, the technical problem to be solved by the utility model is to provide a short edge folding mechanism of box nailing machine for solving the above problems.
[0004] To this end, the utility model is realized by the following scheme:
[0005] A short edge folding mechanism of box nailing machine, characterized by comprising a lifting seat, the lifting seat is connected with a lifting drive assembly, a short edge folding plate is arranged on the lifting seat, a floating frame is arranged on the lifting seat, an elastic member is arranged between the floating frame and the lifting seat, a guide assembly is arranged corresponding to the floating frame, a pressure plate roller is arranged on the floating frame, a stop block is arranged corresponding to one side of the pressure plate roller, when the lifting seat acts to perform short edge folding, the pressure plate roller first presses the long edge part of the paperboard on the stop block, and then the short edge folding plate extrudes the short edge to bend.
[0006] The lifting drive assembly comprises a linear motor, and the telescopic part of the linear motor is connected with the lifting seat.
[0007] The guide assembly is a guide column connected to the floating frame, the guide column passes through the guide sleeve on the lifting seat, and the elastic member is a spring, which is sleeved on the outside of the guide column.
[0008] A positioning baffle is arranged corresponding to one side of the short edge folding plate, the positioning baffle has an extension part, a strip-shaped groove is formed in the extension part, and the extension part is fixed by screwing the fastener through the strip-shaped groove and the rack.
[0009] The short edge folding mechanism of the carton nailing machine has the advantages that when short edge folding is performed, the long edge part of the paperboard is pressed tightly on the stop block by the pressing plate roller on the floating frame, and then subsequent short edge folding operation is performed, so that the position of the long edge part of the paperboard does not deviate during the short edge folding operation, the short edge can be bent along the preset crease, and thus the short edge folding quality of the paperboard is effectively improved. BRIEF DESCRIPTION OF DRAWINGS
[0010] The utility model has the following drawings:
[0011] Figure 1 The utility model is a structural schematic view;
[0012] Figure 2 The utility model is Figure 1 Another view. DETAILED DESCRIPTION
[0013] As shown in the figure, the short edge folding mechanism of the carton nailing machine disclosed by the utility model comprises a lifting seat 2, the lifting seat 2 is connected with a lifting drive assembly, the lifting seat 2 is provided with a short edge folding plate 7, the lifting seat 2 is provided with a floating frame 3, an elastic member 5 is arranged between the floating frame 3 and the lifting seat 2, a guide assembly is arranged corresponding to the floating frame 3, a pressing plate roller 6 is arranged on the floating frame 3, a stop block 9 is arranged corresponding to one side of the pressing plate roller 6, when the lifting seat 2 is actuated to perform short edge folding, the pressing plate roller 6 first presses the long edge part of the paperboard on the stop block 9, and then the short edge folding plate 7 extrudes the short edge to bend.
[0014] Further, the lifting drive assembly comprises a linear motor 1, and the telescopic part of the linear motor 1 is connected with the lifting seat 2. By controlling the linear motor 1, the lifting seat 2 can be actuated. Of course, in addition to the linear motor, common linear drive structures such as a cylinder, a gear and rack structure and a synchronous belt structure can also be used to actuate the lifting seat 2.
