[0058] Among them, the displacement distance of the protrusion 3 can be adjusted by the electric hydraulic push rod 26, and the cardboard surface of the packaging box can be selected to be subjected to folding and indentation forming processing of different depths. At the same time, the winding amount of the rope 33 can be adjusted with the help of two servo motors 32 on the periphery of the electric hydraulic push rod 26, so that the elastic steel plate 35 located at the bottom end of the protrusion 3 can be adjusted to have different curvature adjustment effects, so that the cardboard of the packaging box can select different indentation ranges and indentation sizes when performing folding and indentation processing. When the curvature of the elastic steel plate 35 is large, the indentation of the cardboard of the packaging box is small. When the curvature of the elastic steel plate 35 is small, the indentation of the cardboard of the packaging box will be large.

[0059] like Figure 1 、 Figure 5 、 Figure 8 、 Figure 9 and Figure 10 As shown, both ends of the outer periphery of the protrusion 3 are fixedly connected to support blocks 36 by bolts, and the ends of the support blocks 36 are rotatably connected to sleeves 37 through a rotating shaft.

[0060] Among them, by adjusting the position angle of the sleeve 37 on the support block 36 and positioning it with the help of the lock 39, and at the same time adjusting the position of the insertion rod 38 in the sleeve 37, it is possible to match the protrusion 3 to form indentation effects of different shapes and sizes on the cardboard of the packaging box.

[0061] Example 4:

[0062] like Figure 1 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10As shown, a packaging box folding and creasing forming device includes: a base 1, a support plate 16 arranged at the upper end of the base 1, and a top seat 17 arranged on the top of the support plate 16, a mounting platform 11 is arranged above the base 1, a support platform 4 is arranged above the mounting platform 11, a controller 5 is fixedly connected to the outer side of the mounting platform 11 by bolts, and a power supply 51 is fixedly connected to one side of the support plate 16 by bolts; it also includes: a displacement clamping assembly, arranged above the base 1; a deflection pressure assembly, arranged below the top seat 17; a pressure head assembly, arranged at the power output end of the deflection pressure assembly; and an ejection component matching the pressure head assembly is arranged above the support platform 4.

[0064] Among them, by opening the arc groove 41 on the support 4, the protrusion 3 and the elastic steel plate 35 can provide an arc-shaped force-bearing surface for the cardboard during the pressure application process, thereby improving the forming force effect when the cardboard is subjected to large-area folding and indentation processing.

[0069] The rollers 52 provided at both top ends of the arc-shaped groove 41 can reduce friction when the cardboard of the packaging box moves on the support platform 4, thereby facilitating the movement of the cardboard of the packaging box.

[0070] Embodiment 5:

[0071] like Figure 1 As shown, a method for forming a packaging box edge folding and creasing device includes the following steps:

[0072] S101. Place the cardboard of the packaging box on the pallet 4 and on the inner side of the displacement clamping assembly. Adjust the displacement clamping assembly so that the two ends of the cardboard of the packaging box are in contact with the inner wall of the displacement clamping assembly. After contact, increase the clamping strength of the displacement clamping assembly so that the cardboard of the packaging box can be moved back and forth on the pallet 4 through the displacement clamping assembly.

[0073] Among them, the cardboard of packaging boxes of various sizes can be clamped and fixed by the displacement clamping component, and positioned on the support platform 4 to avoid the offset effect during the indentation process.

[0074] S102. According to the location where the folding and indentation are required to be formed on the cardboard of the packaging box, the deflection pressure component is driven to adjust the extension direction of the pressure head component so that when the bottom end of the pressure head component contacts the cardboard surface of the packaging box, the cardboard of the packaging box is positioned by the displacement clamping component. At this time, the deflection pressure component is driven again to increase the displacement distance of the pressure head component so that the desired folding and indentation are formed on the cardboard surface of the packaging box.

[0075] The displacement distance and displacement angle of the pressure head assembly can be adjusted by deflecting the pressure applying assembly, so that the cardboard of the packaging box on the displacement clamping assembly can be indented at multiple positions and angles.

[0076] S103. Before the bottom end of the pressing head assembly is separated from the cardboard surface of the packaging box with the help of the deflection pressure assembly, the contact area between the pressing head assembly and the cardboard surface of the packaging box is adjusted so that the contact area between the pressing head assembly and the cardboard of the packaging box after adjustment is larger than the contact area before adjustment, and the pressing head assembly is driven by the deflection pressure assembly to apply pressure to the cardboard of the packaging box again, so as to form arc-shaped depressions on both sides of the portion where the folding indentation is formed in step S102.

[0077] The indentation shape can be effectively adjusted by adjusting the contact area between the indenter assembly and the packaging box cardboard.

[0078] S104, adjusting the protruding height of the ejection component above the support platform 4 to cooperate with the pressure head assembly to press and form the bottom of the folding and creasing portion of the cardboard of the packaging box, thereby achieving double-sided folding and creasing processing.

[0079] Among them, by providing an ejection component with an adjustable extension distance on the support platform 4, it can cooperate with the press head assembly to perform double-sided indentation processing on the cardboard, further improving the two-way bending effect after the folding indentation is formed.

[0080] Working principle: When in use, the horizontal position of the two clamping plates 14 can be adjusted by adjusting the extension of the first electric telescopic rod 12 and the second electric telescopic rod 13, so that the clamping range between the two clamping plates 14 can be adjusted according to the cardboard of the packaging box with different sizes. After the cardboard of the packaging box is clamped and fixed, the first electric telescopic rod 12 and the second electric telescopic rod 13 are driven synchronously to make the two clamping plates 14 move synchronously, thereby driving the position of the cardboard of the packaging box on the support platform 4 to be adjusted. The electric hydraulic push rod 26 is deflected by the driving action of the turntable 24, so that the pressure head assembly can adjust the angle when folding and creasing the cardboard of the packaging box.
