[0029] The following describes the embodiments and related details and working principles of this utility model with reference to the accompanying drawings. The cardboard edge-wrapping mechanism is used to wrap the sides of the cardboard. At this time, the cardboard 1 and the face paper 2 are bonded together, with the face paper on the bottom and the cardboard on top, and the face paper is larger than the cardboard. The excess part of the face paper 2 is used for edge wrapping.

[0030] This cardboard edge-wrapping mechanism includes a frame, a first side-folding component, and a second inner-folding component. The first side-folding component includes a support plate 4 and a positioning element 3. The positioning element 3 is positioned above the support plate 4 and moves up and down relative to the support plate 4. The positioning element 3 can be a positioning plate. The second inner-folding component includes an edge-wrapping plate 5 and a drive assembly 6 that moves the edge-wrapping plate 5 horizontally and obliquely. The first side-folding component moves up and down relative to the edge-wrapping plate 5, and the edge-wrapping plate 5 is positioned on the outside of the support plate 4. During the cardboard edge-wrapping operation, the cardboard is fed onto the support plate 4, and the face paper is placed on the edge-wrapping plate 5. The positioning element 3 moves down to press down on the cardboard to be wrapped on the support plate 4. The positioning element 3 and the support plate 4 clamp the cardboard and move it down relative to the edge-wrapping plate 5, making the cardboard lower than the edge-wrapping plate 5. The edge-wrapping plate folds the face paper at the bottom of the cardboard upwards. (See attached image) Figure 1 The process involves two steps: first, the face paper is folded upwards along the bottom side edge 17 of the cardboard, achieving the first side fold; then, the edge-sealing plate 5 horizontally and diagonally pushes the upwardly folded face paper inwards, making it adhere to the upper surface of the cardboard, i.e., the face paper is folded inwards along the top side edge 16 of the cardboard until it adheres to the cardboard, achieving the second inward fold, thus completing the edge sealing of the cardboard. After the edge sealing is completed, the drive assembly 6 drives the edge-sealing plate to move horizontally upwards and reset, and the positioning member 3 also moves upwards. At this point, the edge-sealed cardboard can be sent away. This utility model completes the edge sealing of the cardboard in two steps, with fast sealing speed, high efficiency, and excellent sealing quality.

[0031] See attached Figure 2 The first side-folding component and the second inner-folding component are provided in two sets, left and right. The frame includes a mounting plate and a horizontally arranged guide rod 14. The mounting plate is divided into a left mounting plate and a right mounting plate. The two sets of first side-folding components and second inner-folding components are respectively mounted on the left mounting plate and the right mounting plate. The left mounting plate and the right mounting plate are slidably mounted on the guide rod 14. The spacing between the two sets of first side-folding components and the second inner-folding component is adjusted according to the width of the cardboard. The two sets of first side-folding components and second inner-folding components can simultaneously edge both sides of the cardboard, or they can edge only one side of the cardboard.

[0032] The positioning component 3 has two strokes. In the first step, the positioning component moves down to press down on the cardboard on the pallet. In the second step, the positioning component and the pallet move down together to complete the first side fold. The first side folding component includes a lifting seat 9 that moves up and down on the frame. The pallet 4 is mounted on the lifting seat. The lifting seat 9 is equipped with a first power component 11 that drives the positioning component 3 to move up and down. After the first power component 11 drives the positioning component 3 to move down and press down on the cardboard, the lifting seat 9 moves up and down, causing the positioning component 3 and the pallet 4 to move down synchronously. The frame is equipped with a vertically arranged guide rail 15. The lifting seat is slidably mounted on the guide rail 15 and is connected to a third power component 13 that drives its movement.

[0033] The drive assembly 6 includes a first rotating shaft group 61 and a second rotating shaft group 62 arranged vertically in parallel, and a connecting component. Both the first rotating shaft group 61 and the second rotating shaft group 62 include a first rotating shaft and a second rotating shaft arranged horizontally in parallel. The two rotating shafts of the first rotating shaft group 61 are rotatably mounted on a vertical plate 67, which is connected to the edge-sealing plate 5. The two rotating shafts of the second rotating shaft group 62 are rotatably mounted on a frame. (See attached image) Figure 3 and 4 The two shafts of the second rotating shaft group 62 are rotatably mounted on the lower upright plate, which is installed on the mounting plate. The first rotating shaft of the second rotating shaft group 62 is connected to the second power component 12 that drives its reciprocating rotation. The support plate 4, positioning component 3, edge-binding plate 5, first rotating shaft group 61, second rotating shaft group 62, and connecting components are all located above the mounting plate. The first power component 11, second power component 12, and third power component 13 are located below the mounting plate, resulting in a reasonable layout and ease of maintenance. The connecting components include a first connecting component 63 and a second connecting component 66 arranged parallel to each other. The first connecting component 63 is installed on the first rotating shaft of both the first rotating shaft group 61 and the second rotating shaft group 62, and the second connecting component 66 is installed on the second rotating shaft of both the first rotating shaft group 61 and the second rotating shaft group 62. The parallelogram transmission structure allows the edge-binding plate 5 to move stably horizontally and obliquely. The edge-binding plate 5 can both push the face paper inward to fold and simultaneously move downward to completely adhere the face paper to the cardboard, achieving this in one step and improving efficiency. Both ends of the first shaft of the second rotating shaft assembly 62 are connected to connecting rods 64, and the two connecting rods 64 are connected to the connecting shaft 65. The second power component 12 is a cylinder, which is rotatably mounted on the frame, and the output end of the cylinder is rotatably connected to the connecting shaft 65. See attached document. Figure 4 and 5 The cylinder drives the connecting shaft 65 to move upward, and the connecting rod 64 swings upward, causing the first rotating shaft of the second rotating shaft group 62 to rotate clockwise. Through the first connecting piece 63 and the second connecting piece 66, the upright plate and the edge plate 5 move horizontally to the lower right. Both the first power component 11 and the third power component 13 can be cylinders.

[0034] The cardboard edge-wrapping mechanism also includes a conveying component, which includes a conveyor belt 7 and a drive wheel 8. The conveyor belt 7 is mounted on the drive wheel 8, and the drive wheel 8 is rotatably mounted on the lifting seat 9. The conveyor belt 7 is located on the inner side of the pallet 4, and the height of the conveyor belt 7 is adapted to the pallet 4. The conveyor belt 7 carries away the edge-wrapped cardboard to make way for the next cardboard edge-wrapping operation.

[0035] To improve efficiency, the conveying component also includes a suction device that moves up and down. The suction device moves back and forth between the picking station and the edge-wrapping station. The suction device delivers the cardboard to the pallet 4. During the edge-wrapping operation of the cardboard, the suction device picks up the cardboard, making reasonable use of the operation time and improving production efficiency.

[0036] Appendix Figure 5 In the diagram, the cardboard has a groove 18, and the distance from the groove 18 to the side of the cardboard is relatively narrow. This type of cardboard edge binding is called narrow edge binding. In the diagram, the left side of the cardboard 1 has been edged, but the right side of the cardboard has not yet been edged. Taking the right side edge binding as an example, the positioning member is pressed on the inside of the groove. The cardboard 1 on the outside of the groove can move up and down, so the first side fold cannot be completed. To solve this problem, the first side folding component also includes an auxiliary positioning member 19. The auxiliary positioning member is set above the tray 4 and outside the positioning member 3. That is, the auxiliary positioning member 19 presses the cardboard close to the side of the cardboard. The auxiliary positioning member can move up and down relative to the tray and the positioning member. When wrapping the narrow edge, the positioning member and the auxiliary positioning member move down to press down on the cardboard to be wrapped on the pallet, while the auxiliary positioning member presses down on the cardboard on the outer side of the groove, thus fixing the cardboard on the outer side of the groove. The positioning member, the auxiliary positioning member, and the pallet clamp the cardboard and move it down relative to the wrapping plate, making the cardboard lower than the wrapping plate. The wrapping plate folds the bottom face paper of the cardboard upward, achieving the first side fold. Then, the auxiliary positioning member moves up to make room for the face paper and the wrapping plate. The wrapping plate pushes the upward-folded face paper horizontally and diagonally downward to fold it inward, making the face paper adhere to the upper surface of the cardboard, achieving the second inward fold. Figure 2 In the middle, the auxiliary positioning component is connected to the cylinder 20 that drives its lifting and lowering. The cylinder is connected to the positioning component 3. That is, when the positioning component moves down to press the cardboard, the auxiliary positioning component moves down to press the cardboard. When the edge banding plate is wrapping the edge, the cylinder drives the auxiliary positioning component to move upward relative to the positioning component. When resetting, the cylinder drives the auxiliary positioning component to move downward relative to the positioning component.

[0037] The following description, using the example of edge wrapping with the attached drawings, further illustrates the following: In the initial state, the edge wrapping plate 5 is located outside the pallet 4, the lifting seat 9 is in a high position, and the positioning plate 3 and auxiliary positioning component 19 are above the pallet 4 with their bottoms at the same height. The suction component delivers the cardboard from the material picking station to the edge wrapping station. The suction component moves downward to place the cardboard on the pallet 4, and the face paper on the lower surface of the cardboard is placed on the edge wrapping plate 5. The first power component 11 drives the positioning component 3 and auxiliary positioning component 19 to move downward and press them against the pallet 4, thus fixing the cardboard. (See attached drawings) Figure 1 and 2The third power component 13 drives the lifting seat 9 to move downwards. The positioning component 3, auxiliary positioning component 19, and pallet 4 clamp the cardboard and move it downwards, making the cardboard lower than the edge-sealing plate 5. That is, the face paper moves downwards relative to the edge-sealing plate 5. The face paper is restricted by the edge-sealing plate 5, so that the face paper placed on the edge-sealing plate 5 folds upwards along the bottom side edge 17 of the cardboard, realizing the first side fold. Then, the auxiliary positioning component moves upwards, and only the positioning component presses down on the cardboard. The second power component 12 drives the connecting rod 64 to swing upwards, so that the edge-sealing plate 5 moves horizontally inwards and diagonally downwards and presses against the pallet 4. That is, the left edge-sealing plate 5 moves horizontally to the lower right, and the right edge-sealing plate 5 moves horizontally to the lower left. The edge-sealing plate 5 pushes the upwardly folded face paper to fold inwards along the top side edge 16 of the cardboard until the face paper is attached to the upper surface of the cardboard, realizing the second inward fold. In this way, the edge-sealing of the cardboard is completed. The second power component drives the connecting rod 64 to swing downwards, and the edge-sealing plate 5 moves horizontally and obliquely upwards. The first power component drives the positioning component 3 and the auxiliary positioning component 19 to move upwards. The conveyor belt 7 drives the paperboard that has been edge-sealed forward, so that the paperboard leaves the edge-sealing station. Finally, the lifting seat 9 moves upwards and the auxiliary positioning component 19 moves downwards, returning to the initial state. The pallet 4 then receives the paperboard to be edge-sealed again sent by the suction component.
