[0033] In use, the existing corrugated cardboard is placed on the vacuum suction plate 31 and vacuum-adsorbed. Then, the three sides of the corrugated cardboard at both ends of the longitudinal direction are clamped and positioned by the corresponding three positioning clamps A34. The shaping clamp 33 can pass vertically between the corresponding vacuum suction plate 31 and the flipping plate 32 and move laterally towards the corresponding shaping pressure plate 41, so that the folded edge of the cardboard is shaped between the shaping pressure plate 41 and the shaping clamp 33. The flipping plate 32 can flip the folded edge of the cardboard and press the folded edge flat, thereby completing the bending and pressure-holding bonding of the folded edge.

[0034] Preferably, the vacuum suction plate 31 includes a suction plate body, and several vacuum suction cups B311 are embedded in the top of both ends of the suction plate body along the horizontal direction. The vacuum suction cups B311 are used to adsorb and fix the corrugated cardboard. Here, the vacuum suction plate 31 is fixed on the frame 1 by a support base 312.

[0035] As an embodiment of this utility model, both ends of the inner side of the flip plate 32 are fixedly provided with adjustment seats 321, and the adjustment seats 321 are fixedly provided with rotating shafts 322. The rotating shafts 322 are rotatably mounted on the mounting base 313, which is fixedly mounted on the frame 1. One of the rotating shafts 322 is driven to rotate by a drive mechanism, and the outer end of the other rotating shaft 322 is fixedly provided with a trigger rod 314.

[0038] Correspondingly, the worktable 2 is provided with matching cross-shaped holes, which will not be described in detail here.

[0039] As an embodiment of the present invention, the drive mechanism includes a motor 35 and two pulleys 351 driven by a synchronous belt 352; one pulley 351 is fixed on a corresponding rotating shaft 322, and the other pulley 351 is driven by the motor 35; the motor 35 is fixed on a corresponding mounting base 313.

[0040] As an embodiment of this utility model, the bottom of the vacuum suction plate 31 is fixedly connected to a lifting seat 317 by several pillars 316. Above the lifting seat 317, there is a lifting seat 36 driven by a bidirectional cylinder 318. The lifting seat 36 is fixedly provided with guide rails A361 on both sides of the horizontal direction. The guide rails A361 are provided with matching sliders A362, which are fixed on the lifting seat 317. The top of the lifting seat 36 is provided with two moving modules that are driven horizontally by finger cylinders 37. The shaping clamp 33 is vertically fixed on the corresponding moving modules.

[0041] When the bidirectional cylinder 318 drives the lifting seat 36, the lifting seat 36 moves up and down relative to the top seat 317, thereby causing the shaping clamp 33 to move up and down; at the same time, the finger cylinder 37 on the lifting seat 36 drives the moving module to move laterally, thereby causing the shaping clamp 33 to move laterally; thus, the shaping clamp 33 and the shaping pressure plate 41 cooperate with each other.

[0042] The bottom of the aforementioned lifting seat 36 may be provided with a plurality of guide posts 363. The guide posts 363 slide through the lifting seat 317 and are fixedly provided with a limiting plate 364 at the bottom. A vertical hydraulic buffer A365 is fixedly provided at the top of the limiting plate 364, and a vertical hydraulic buffer B366 is provided below the limiting plate 364. The hydraulic buffer B366 is fixed on the lifting seat 317. The hydraulic buffer A365 abuts against the lifting seat 317, and the hydraulic buffer B366 abuts against the limiting plate 364, thereby improving the lifting stability of the lifting seat 36.

[0043] The movable module here includes a connecting plate 371; one end of the connecting plate 371 is fixed on the push rod of the corresponding finger cylinder 37, and the bottom of the other end is fixed with a guide rail B372.

[0045] As an embodiment of this utility model, the shaping pressure plate 41 is fixed on the slide of the slide cylinder A42, the cylinder body of the slide cylinder A42 is fixed on the slide of the slide cylinder B44 through the adapter plate 43, the cylinder body of the slide cylinder B44 is fixed on the connecting seat 45, the connecting seat 45 is fixed on the gantry frame 21, and the gantry frame 21 is horizontally fixed on the worktable 2.

[0046] When the corrugated cardboard is adsorbed onto the vacuum suction plate 31, the shaping pressure plate 41 descends and presses down on the cardboard, the shaping clamp 33 pre-bends the folded edge of the cardboard, and then the flip plate 32 rotates 180 degrees, pushes the folded edge and presses it firmly into place. The folded edge is pressed between the flip plate 32 and the vacuum suction plate 31, thus achieving the effect of cardboard pasting and pressure retention.

[0047] As an embodiment of this utility model, the gantry frame 21 is also provided with a pressure holding component 5. The pressure holding component 5 includes a mounting plate 51. The bottom of the mounting plate 51 is provided with two vertical telescopic cylinders 52 along the horizontal direction. The air rod of the telescopic cylinder 52 is fixed with a push plate 53. The bottom of the push plate 53 is fixed with a sponge pressing block A54. The top of the push plate 53 is fixed with four rectangularly distributed guide rods 55, which slide through the mounting plate 51. A sponge pressing block B56 is fixed on the worktable 2 directly below the sponge pressing block A54. Three positioning clamps B57 for limiting and clamping the cardboard are provided on both sides of the middle of the two sponge pressing blocks B56 along the longitudinal direction. The positioning clamps B57 are fixed on the dual-axis cylinder B58, which is fixed on the bottom of the worktable 2. The worktable 2 is provided with rectangular holes that match the corresponding positioning clamps B57.

[0048] In one embodiment of this utility model, the workbench 2 is provided with a longitudinal conveying component 6 and a transverse conveying component 7. Both the longitudinal conveying component 6 and the transverse conveying component 7 include a linear module 61 and a sliding plate 62 driven by the linear module 61. A slide cylinder C63 is fixed on the slide plate 62, and a bracket 64 is fixed on the slide of the slide cylinder C63. The bottom of the bracket 64 is provided with several vacuum suction cups A65 for longitudinally adsorbing cardboard. This ensures the handling of corrugated cardboard, improves production efficiency, and is suitable for automated production lines.

[0049] The linear module 61 here is an existing purchased component, commonly categorized into synchronous belt type, ball screw type, and linear motor type. The synchronous belt type linear module mainly consists of a belt, linear guide rail, aluminum alloy profile, coupling, motor, and photoelectric switch; the ball screw type linear module mainly consists of a ball screw, linear guide rail, aluminum alloy profile, ball screw support, coupling, motor, and photoelectric switch; the linear motor module mainly consists of a moving stator, guide rail, magnetic grid, and sensor, etc., and will not be elaborated further.

[0050] The aforementioned longitudinal conveying assembly 6 may also include a longitudinal rodless cylinder 66. The cylinder body of the rodless cylinder 66 is fixed on the bracket 64. Several support plates 67 are provided at the bottom of the guide rail of the rodless cylinder 66. Corresponding vacuum suction cups A65 are fixed at both ends of the support plates 67.

[0051] When the adsorbed corrugated cardboard approaches the flange assembly 3, the rodless cylinder 66 drives the corresponding vacuum suction cup A65 to move longitudinally and place the corrugated cardboard on the vacuum suction plate 31, further saving operating space and avoiding interference problems.

[0052] like Figure 1 As shown, the X-axis is the longitudinal direction, and the Y-axis is the transverse direction. The working process of this utility model is as follows:

[0053] Step 1: Longitudinal feeding

[0054] The longitudinal conveying component 6 picks up the corrugated cardboard and sends it to the flanging component 3. The vacuum suction plate 31 picks up the corrugated cardboard, and at the same time, the corresponding positioning clamp A34 positions and clamps the three sides of the two longitudinal ends of the corrugated cardboard.

[0055] Step 2: Flip and pre-fold

[0056] The shaping plate 41 descends and presses down on the corresponding folding line of the corrugated cardboard, and the flipping plate 32 rotates from the plane to the vertical position to complete the pre-bending of the cardboard.

[0057] Step 3: Folding and Shaping

[0058] The shaping clamp 33 first moves horizontally outward, then rises vertically, thereby pushing the folded edge of the cardboard upward; then it moves towards the shaping pressure plate 41, so that the folded edge is vertically clamped between the shaping clamp 33 and the shaping pressure plate 41, thus completing the folding edge shaping.

[0059] Step 4: Compacting

[0060] The shaping clamp 33 is reset below the vacuum suction plate 31, and the shaping pressure plate 41 is raised and reset; the flipping plate 32 rotates from vertical to flat, and the folded edge of the corrugated cardboard is pressed and glued to the cardboard, which plays the role of bending and pressure retention.

[0061] Step 5: Lateral feeding and secondary pressure holding

[0062] The transverse conveyor assembly 7 picks up the corrugated cardboard from the vacuum suction plate 31 and sends it to the pressure holding assembly 5. At this point, the cardboard is placed on the sponge pressure block B56; the corresponding positioning clamps B5 position and clamp the three sides of the longitudinal ends of the corrugated cardboard; the sponge pressure block A54 descends, so that the folded edge of the corrugated cardboard is positioned between the corresponding sponge pressure block A54 and the positioning clamps B5, achieving the purpose of the second pressure holding and ensuring that the folded part is firmly glued. Then, the corrugated cardboard is transferred to the next process.

[0063] In addition, a protective fence 22 can be installed on the workbench 2, the details of which will not be elaborated further. This utility model is applicable to automated production lines, can replace manual labor, ensure mass production and production quality, and reduce production costs.

[0064] This utility model can be summarized in other specific forms that do not depart from the spirit or main features of this utility model. Therefore, in all respects, the above embodiments of this utility model should only be considered as descriptions of this utility model and not as limitations thereof. The claims specify the scope of this utility model, while the above description does not specify the scope of this utility model.
