Technical Field
[0001] The utility model belongs to the field of packaging machinery, and particularly relates to a box veneer folding device. Background Art
[0002] As an important part of commodities, the packaging box plays a very important role in the sales of commodities. With the improvement of people's living standards, people pay more and more attention to the outer packaging of corresponding commodities. For this reason, packaging boxes of different shapes emerge as the times require. For example, an additional decorative cardboard is attached to the front of the packaging box, and there is an upward protruding triangular protrusion at the top sealing position of the front of the packaging box. This kind of packaging box is deeply loved by everyone because of its special shape, but it is not convenient to produce. Usually, after the decorative cardboard is pasted on the front of the packaging box, it is necessary to manually adhere the edges of the decorative cardboard, especially at the triangular protrusion. Therefore, there are problems of low production efficiency, difficult to control accuracy, and difficult to produce quickly and in large quantities. For this reason, people hope to find a production device that can adapt to the rapid and high-precision folding production of the edges of the decorative cardboard on this kind of packaging box.

[0026] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically stated, can be replaced by other equivalent or features with similar purposes. That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.
[0027] As Figures 1-9As shown in the figure, the box veneer hemming device is used to hem the edges of a decorative cardboard 20 after pasting it on the front of the box 10. The box 10 is a cuboid structure with one end open, and a protruding triangular structure 11 extends outward at the upper end of the open end and the end of the front. The decorative cardboard 20 includes a main board 21 with the same shape and size as the front of the box 10, and five side boards 22 that extend outward from five sides of the main board 21 and can wrap the five side parts of the front of the box from three sides adjacent to the front of the box 10 and two outer edges of the triangular structure 11 after folding.
[0028] The box veneer hemming device includes a working platform 1, a hemming mechanism 3 and a flipping mechanism 4 arranged in sequence on the working platform 1. The flipping mechanism 4 includes a flipping cross beam 41 driven by a motor and two box inner lining brackets 42 arranged side by side on the cross beam 41 and adapted to the internal structure of the box. Before the flipping mechanism 4 flips, the two box inner lining brackets 42 are in the hemming processing position above the hemming mechanism 3. After the flipping mechanism 4 flips 180 degrees, the two box inner lining brackets 42 are in the blanking position. The hemming mechanism 3 is used to fold the five side boards 22 of the decorative cardboard 20 onto the box 10.
[0029] The hemming mechanism 3 includes a lifting platform 31 that can move up and down relative to the working platform 1, and two sets of identical hemming components 32 arranged on the lifting platform 31 and located below the positions of the two box inner lining brackets 42 before flipping.
[0030] The hemming component 32 includes three clamping blocks 33 whose positions respectively correspond to three sides adjacent to the front of the box 10, and a front pressing block 34 with a certain thickness and a triangular front end opening corresponding to two outer edges of the triangular structure 11 extending from the front end of the front of the box 10. The clamping blocks 33 and the front pressing block 34 are both arranged above the lifting platform 31. The rear ends of the clamping blocks 33 are all connected with clamping cylinders 35, and the clamping cylinders 35 are all fixed on the lifting platform 31. The lower end of the front pressing block 34 is fixedly connected with the movable end of a jacking cylinder 37 arranged below the lifting platform 31 through a connecting rod 36. The jacking cylinder 37 is fixedly connected with a support plate 39 that can move back and forth below the lifting platform 31 and is driven by a horizontal linear driving device 38.
[0031] A linear guide rail 311 is arranged below the lifting platform 31. A sliding groove matched with the linear guide rail 311 is arranged on the support plate 39. The horizontal linear driving device 38 is fixedly arranged below the lifting platform 31. Through the guidance of the linear guide rail 311, the back-and-forth movement of the support plate 39 is made more stable. More preferably, the horizontal linear driving device 38 is a horizontal driving cylinder.
[0032] The lifting platform 31 is driven by a lifting cylinder 40 fixedly connected to the working platform 1 through a support platform to move up and down relative to the working platform 1. Below the lifting platform 31, several vertical guide rods passing through the support platform are also connected to make the movement of the lifting platform 31 more stable and accurate.
[0033] On the upper part of the side of the clamping block 33 and the front pressing block 34 close to the packaging box 10, arc transition structures are provided to facilitate the folding of the edge plate 22 of the decorative cardboard 20 when the lifting platform 31 rises.
[0034] The front pressing block 34 is an octagonal front pressing block.
[0035] Working process:
[0036] The packaging box 10 with the decorative cardboard 20 already pasted on the front and the glue already applied on the main body board 21 and the five edge boards 22 is completely sleeved on the packaging box inner lining support 42. At this time, the front end of the triangular structure 11 is exactly above the front end opening of the front pressing block 34. Then the lifting platform 31 of the folding mechanism 3 rises. Due to the blocking effect formed by the sides of the three clamping blocks 33 and one front pressing block 34 above the lifting platform 31 facing the packaging box 10 on the outer sides of the packaging box, the five edge boards 22 of the decorative cardboard 20 are respectively folded upward and attached to the packaging box 10. Then the three clamping blocks 33 are pushed by the clamping cylinder 35 to press and fit the three edge boards 22 on the three sides adjacent to the front of the packaging box 10 onto the packaging box 10. At the same time, the front pressing block 34 moves a certain distance into the packaging box 10 under the drive of the horizontal linear drive device 38 and then presses down a certain distance under the drive of the lifting cylinder 37 to press the two edge boards 22 corresponding to the two outer edges of the triangular structure 11 on the packaging box forward and downward onto the two outer edges of the triangular structure 11. Then the front pressing block 34 returns to its original position upward and backward under the drive of the lifting cylinder 37 and the horizontal linear drive device 38, and at the same time the three clamping blocks 33 are loosened, so that the packaging box 10 is completely released. Then the lifting platform 31 descends to return to its original position, and the flipping mechanism 4 flips, driving the two packaging boxes 10 that have completed the folding process to flip 180 degrees from the folding processing position to the blanking position. At the blanking position, blanking is carried out by machine or manually.
[0037] The packaging box veneer folding device of the present utility model has a clever structure and can automatically complete the whole process of accurately folding the five edges of the decorative cardboard after pasting a decorative cardboard on the front of the packaging box. The process is fast, efficient, highly accurate and practical, and is worthy of promotion.
[0038] The utility model is not limited to the foregoing specific embodiments. The utility model extends to any new feature or any new combination disclosed in this specification, as well as any new combination of steps of any new method or process disclosed.
