[0041] Embodiment 1

[0042] like Figure 1 As shown, a folding support card 2 is provided, comprising: a bottom panel 21, a top panel 22, a front panel 23 and a back panel 24. In actual production, the bottom panel 21, the top panel 22, the front panel 23 and the back panel 24 are all integrally cut and formed from paper.

[0043] The front side of the bottom panel 21 is connected to the lower side of the front panel 23, the rear side of the bottom panel 21 is connected to the lower side of the rear panel 24, and the upper side of the rear panel 24 is connected to the rear side of the top panel 22; for the convenience of folding, the connection between the front panel 23 and the bottom panel 21 can be pre-rolled to provide a folding mark for easy folding, so that when the front panel 23 and the bottom panel 21 are folded, the folding can be completed accurately and without error. Similarly, pre-rolling can also be performed between the bottom panel 21 and the rear panel 24 to facilitate the folding between the bottom panel 21 and the rear panel 24.

[0044] However, rolling cannot be performed on all folding parts. If rolling is performed on all folding parts, the entire folding card will lack elasticity, thereby reducing its stability and being prone to falling apart. Therefore, in this embodiment, only the front and rear connecting parts of the bottom panel 21 are rolled, and the other parts are not rolled.

[0045] A hole 25 is provided in the middle of the front panel 23, and a buckle 26 corresponding to the hole 25 is provided on the front side of the top panel 22. The distance between the horizontal midline of the hole 25 and the lower side of the front panel 23 is equal to the height of the rear panel 24. In order to achieve the connection between the top panel 22 and the front panel 23, a hole 25 is provided on the front panel 23, and then a buckle 26 is provided at the corresponding position of the top panel 22. When folding the entire support card, the front panel 23 is first folded (the folding position coincides with the hole 25), the hole 25 is exposed, and then the buckle 26 is inserted into the hole 25. Through the elasticity of the buckle 26 and the upper part of the front panel 23, the entire support card is stabilized into a rectangular structure, which can be supported later.

[0046] Finally, for the sake of connection stability, the hole 25 is preferably a rectangular through hole with the long axis of the rectangular through hole set horizontally; the buckle 26 is a rectangular block with the long side of the rectangular block connected to the front side of the top panel 22, and the width of the top panel 22 is equal to the width of the bottom panel 21.

[0052] The front folding assembly folds the upper half of the front panel 23 ; the rear folding assembly folds the rear panel 24 .

[0053] When the mechanism is in use, the staff first moves the mold 5 out from between the side guards 4, and then pre-folds the folding support card 2, that is, folds the front panel 23, the bottom panel 21 and the rear panel 24 to form a U-shaped structure, and then places the U-shaped folding support card 2 between the two side guards 4, and then places the mold 5 in the U-shaped structure, thereby fixing the unfolded folding support card 2.

[0054] After the fixation is completed, the upper half of the front panel 23 is folded by the front folding component so that the upper half of the front panel 23 is fitted against the upper side surface of the mold 5, and then the top panel 22 is folded upward by the rear folding component so that the top panel 22 is fitted against the upper half of the front panel 23 and the upper side surface of the mold 5, and at the same time, the buckle 26 is connected to the hole 25 to realize the folding of the entire folding support card 2, and finally the front folding component and the rear folding component are reset, and then the folding support card 2 and the mold 5 are taken out of the retaining edge 4, and then the mold 5 is pulled out of the folding support card 2, thereby completing the semi-automatic folding of the folding support card 2.

[0055] In order to avoid misalignment during folding, thereby reducing the precision, the dimensions of the rib 4 and the mold 5 are limited.

[0056] The difference between the distance between the two ribs 4 and the width of the mold 5 is equal to the sum of the thicknesses of the front panel 23 and the rear panel 24, that is, the mold 5 and the ribs 4 just fix the folding support card 2, and because the cardboard has a certain elasticity, a small amount of interference fit can be set for stable fixation, that is, the difference between the distance between the two ribs 4 and the width of the mold 5 is slightly smaller than the sum of the thicknesses of the front panel 23 and the rear panel 24.

[0057] The difference between the height of the retaining edge 4 and the height of the mold 5 is equal to the sum of the thicknesses of the bottom panel 21 and the top panel 22. Similarly, the rear folding component just presses the folding support card 2 together, and a small amount of interference fit can also be set, that is, the difference between the height of the retaining edge 4 and the height of the mold 5 is slightly smaller than the sum of the thicknesses of the bottom panel 21 and the top panel 22.

[0060] The lower side of the folding plate 3 is in contact with the upper side of the rib 4 located at the front side, and the folding cylinder 6 pushes the folding plate 3 to move horizontally, and the moving direction is perpendicular to the rib 4.

[0061] An opening groove 31 is provided on the rear side of the folding plate 3. In order to facilitate the insertion of the buckle 26 into the hole 25, when installing the folding support card 2 described in the second embodiment, the position of the opening groove 31 should match the hole 25, and the length of the opening groove 31 should be not less than the length of the hole 25.

[0062] After the installation of the folding support card 2 is completed, the folding cylinder 6 pushes the folding plate 3 to move, and the folding plate 3 applies a force to the upper half of the front panel 23, so that the front panel 23 is folded into an L shape, and the upper half is in contact with the upper side of the mold 5, and the hole 25 is exposed.

[0065] In order to realize the rotatable connection, an example is provided, the servo electric cylinder 11 is rotatably connected to the base plate 1 through a rotating assembly, the rotating assembly includes an electric cylinder fixing plate 13 and an electric cylinder rotating seat 12, the electric cylinder rotating seat 12 is fixedly connected to the base plate 1 through the electric cylinder fixing plate 13, the cylinder body of the servo electric cylinder 11 is connected to the electric cylinder rotating seat 12, and the rotation direction of the servo electric cylinder 11 is perpendicular to the base plate 1;
