Description
Technical Field
[0001] The utility model relates to puzzle packaging equipment, in particular to a puzzle plate arranging device of a heat shrink film packaging machine. Background Art
[0002] Jigsaw puzzles are typically made up of multiple pieces, which are die-cut from the puzzle board. Some jigsaw puzzles, such as flat jigsaw puzzles, are cut directly from the board during die-cutting, creating individual pieces that are then boxed. This method makes it easy for pieces to be lost during production, and they can also warp during transport due to collisions. Furthermore, finding pieces can be challenging when there are too many pieces.
[0003] Therefore, some current jigsaw puzzles, especially 3D puzzles, typically do not completely cut the puzzle inserts during die-cutting. Instead, the entire puzzle sheet is retained and each piece is numbered. This allows the user to refer to the instructions and remove the corresponding puzzle inserts one by one before assembling the puzzle. This approach not only prevents puzzle inserts from being missed during packaging, but also prevents puzzle inserts from colliding with each other during transportation, causing corners to warp. When packaging these puzzles, the individual puzzle pieces are first bagged with heat-shrink film. A heating device is then used to shrink the film, stacking and enclosing the pieces before packaging. However, current packaging equipment often causes the puzzle pieces to become misaligned during bagging and transport to the heating device. Although the heat-shrink film can force the pieces to align when it shrinks, it can also easily bend the corners of the puzzle pieces, affecting the overall quality of the puzzle. Utility Model Content
[0004] The technical problem to be solved by the present invention is to provide a puzzle piece arranging device for a heat shrink film packaging machine, which can arrange the puzzle pieces before the heat shrink film is heated and shrunk, so that the edges and corners of each puzzle piece are aligned in advance, ensuring that the heat shrink film will not affect the edges and corners of the puzzle pieces after shrinkage.
[0005] In order to solve the above technical problems, the technical solutions adopted are as follows:

[0007] In the above-mentioned puzzle piece sorting device, the front end of the conveying mechanism is connected to the discharge end of the bagging device, and the rear end of the conveying mechanism is connected to the feed end of the heating device. During operation, the puzzle pieces that have been bagged are conveyed along the conveying mechanism. When the puzzle pieces move to the sorting space, the second lifting drive mechanism first drives the rear alignment plate to rise to stop the puzzle pieces; then, the left and right translation drive mechanism drives the left alignment plate to move right / drives the right alignment plate to move left / drives the left and right alignment plates to move toward the middle together, thereby pushing the puzzle pieces to move right / left / toward the middle, until the left and right sides of the puzzle pieces are in contact with the left and right alignment plates respectively, so that the left and right sides of each puzzle piece are aligned; at the same time, the first lifting drive mechanism drives the front alignment plate to rise, and translates it back and forth to drive the left alignment plate to move right / left / toward the middle together. The driving mechanism drives the front alignment plate to move backward / drives the rear alignment plate to move forward / drives the front alignment plate and the rear alignment plate to move toward the middle together, thereby pushing the puzzle pieces to move backward / forward / toward the middle, until the front and rear sides of the puzzle pieces are in contact with the front alignment plate and the rear alignment plate respectively, so that the front and rear sides of each puzzle piece are aligned; finally, the second lifting drive mechanism drives the rear alignment plate down again, so that the puzzle piece can be directly conveyed from the rear of the conveying mechanism to the heating device, so that the heat shrink film can shrink along the contour of the puzzle piece after being heated, and the corners of the puzzle piece will not be bent, thereby effectively ensuring the quality of the puzzle.
[0008] In the front-to-back direction, the position that the puzzle piece passes through first is the front, and the position that the puzzle piece passes through later is the back.
[0009] In a preferred embodiment, the jigsaw puzzle piece arrangement device further includes a first fixed frame, and the front-to-back translation drive mechanism includes a position adjustment frame, an adjustment mechanism capable of driving the position adjustment frame to move forward and backward, and a front-to-back pushing mechanism capable of driving the front alignment plate to move forward and backward.

At the same time, for jigsaw puzzle pieces of different specifications, the position of the front alignment plate can be pre-adjusted by the adjustment mechanism so that the minimum distance between the front alignment plate and the rear alignment plate matches the length of the jigsaw puzzle piece.

The front and rear alignment plates can be composed of multiple alignment blocks, each of which can be located in the gap between adjacent endless belt units. When the puzzle pieces need to be aligned front and back, the lifting drive mechanism drives the corresponding alignment blocks to rise, so that the alignment blocks pass through the gap to expose the endless belt. Then, the front and rear pushing mechanisms drive the alignment blocks of the front alignment plate to translate, so that the alignment blocks of the front alignment plate push the puzzle pieces.

[0022] In the above-mentioned jigsaw puzzle piece sorting device, the front end of the conveying mechanism 1 is connected to the discharge end of the bagging device, and the rear end of the conveying mechanism 1 is connected to the feed end of the heating device. During operation, the jigsaw puzzle pieces that have been bagged are conveyed along the conveying mechanism 1. When the jigsaw puzzle pieces move to the sorting space, the second lifting drive mechanism 5 first drives the rear alignment plate 4 to rise and stop the jigsaw puzzle pieces; then, the left and right translation drive mechanism 9 drives the left alignment plate 7 to move to the right, thereby pushing the jigsaw puzzle pieces to move to the right, until the left and right sides of the jigsaw puzzle pieces are in contact with the left alignment plate 7 and the right alignment plate 8 respectively, so that the left and right sides of each jigsaw puzzle piece are aligned; at the same time, the first lifting drive mechanism 3 drives the front alignment plate 2 to rise and translate back and forth. The driving mechanism 6 drives the front alignment plate 2 to move backward, thereby pushing the puzzle piece to move backward until the front and rear sides of the puzzle piece are in contact with the front alignment plate 2 and the rear alignment plate 4 respectively, so that the front and rear sides of each puzzle piece are aligned; finally, the second lifting driving mechanism 5 drives the rear alignment plate 4 down again, so that the puzzle piece can be directly conveyed from the rear of the conveying mechanism 1 to the heating device, so that the heat shrink film can shrink along the contour of the puzzle piece after being heated, and the corners of the puzzle piece will not be bent, thereby effectively ensuring the quality of the puzzle.
[0023] The jigsaw puzzle piece arrangement device also includes a first fixed frame 10. The front-to-back translation drive mechanism 6 includes a position adjustment frame 601, an adjustment mechanism 602 capable of driving the position adjustment frame 601 to move forward and backward, and a front-to-back pushing mechanism 603 capable of driving the front alignment plate 2 to move forward and backward. The adjustment mechanism 602 is disposed on the first fixed frame 10, and the front-to-back pushing mechanism 603 is disposed on the position adjustment frame 601. When aligning the jigsaw puzzle pieces, the front alignment plate 2 is driven backward by the front-to-back pushing mechanism 603. This allows the jigsaw puzzle pieces to be quickly moved to the heating device after alignment is completed, ensuring that the pieces are not misaligned after long-distance transportation. Furthermore, for jigsaw puzzle pieces of different specifications, the position of the front alignment plate 2 can be pre-adjusted by the adjustment mechanism 602 so that the minimum distance between the front alignment plate 2 and the rear alignment plate 4 matches the length of the jigsaw puzzle piece.

Two guide sleeves 6025 that can move back and forth along the guide rod 6024 are sleeved on the guide rod 6024. The position adjustment frame 601 is connected to the nut 6023 and the guide sleeve 6025 respectively.
[0025] The conveying mechanism 1 includes a conveying motor 101, a driving roller 102, a driven roller 103, and an endless belt 104. The motor is mounted on a lifting seat, and the driving roller 102 and the driven roller 103 are rotatably mounted on a frame. The driving roller 102 is in driving connection with the power output shaft of the conveying motor 101, and the driving roller 102 and the driven roller 103 jointly tension the endless belt 104. The endless belt 104 can be composed of a plurality of side-by-side endless belt units 1041. The driving roller 102 is provided with a plurality of side-by-side driving pulleys, and the driven roller 103 is provided with a plurality of side-by-side driven pulleys.

The above-mentioned front alignment plate 2 and rear alignment plate 4 can be composed of multiple alignment blocks, and each alignment block can be located in the gap between adjacent annular belt units 1041. When it is necessary to align the puzzle pieces front and back, the lifting drive mechanism drives the corresponding alignment blocks to rise respectively, so that the alignment blocks pass through the gap to expose the annular belt 104, and then the front and rear pushing mechanism 603 drives the alignment blocks of the front alignment plate 2 to translate, so that the alignment blocks of the front alignment plate 2 push the puzzle pieces.

[0027] With this arrangement, the positions of the left alignment plate 7 and the right alignment plate 8 can be pre-adjusted for puzzle pieces of different sizes, so that the minimum distance between the left alignment plate 7 and the right alignment plate 8 matches the width of the puzzle piece. The aforementioned connection method between the left and right translation drive mechanism 9 and the second fixing frame 11 is to provide a through hole in the second fixing frame 11, and to provide a strip guide hole running left and right in the left and right translation drive mechanism 9. Bolts are sequentially passed through the strip guide hole and the through hole and then threadedly connected to the nut 6023. To adjust, the nut 6023 is loosened, the left and right translation drive mechanism 9 is moved as needed, and the nut 6023 is tightened again after the movement is completed. The connection method between the above-mentioned right alignment plate 8 and the second fixing frame 11 is to provide a guide sleeve on the second fixing frame 11, and provide a left-right guide column on the left alignment plate 7 or the right alignment plate 8.
