[0036] See Figures 1 to 9 The carton conveying device shown includes a carrier frame 1, a drive assembly, and a connecting assembly 4, wherein:

[0037] The support frame 1 includes an annular frame 11 and a support member. The annular frame 11 is surrounded on all four sides and runs through the vertical direction. The support member is set on the annular frame 11 and is used to support the carton.

[0038] See Figure 8 and 9The load-bearing component includes a support frame 12 and a support plate 13. The support frame 12 is connected between the support plate 13 and the annular frame 11. That is, in the vertical direction, the support plate 13, the support frame 12, and the annular frame 11 are arranged sequentially. The support frame 12 is a hollow frame structure, with its four sides closed and its vertical direction open. The support frame 12 is composed of multiple horizontal bars along the X-axis, vertical bars along the Y-axis, and vertical bars along the Z-axis. While ensuring support strength, the load-bearing frame 1 is relatively lightweight and can transport a large number of cartons. In this example, the palletizer neatly stacks multiple cartons on a pallet, and then places the pallet carrying the multiple cartons on the load-bearing frame 1.

[0039] The support plate 13 is strip-shaped, and the extension direction of the support plate 13 is consistent with the paper tray conveying direction. A baffle 16 is provided on the support plate 13. The baffle 16 is located at the upper end of the support plate 13 away from the annular frame 11. The baffle 16 extends in the vertical direction and is used to prevent the pallet carrying multiple cartons from detaching from the support frame 1, so as to transport the cartons more stably.

[0040] In some embodiments, multiple support plates 13 are provided, and the multiple support plates 13 are distributed in a direction perpendicular to the paper tray conveying direction. A gap is maintained between two adjacent support plates 13. The multiple support plates 13 are provided to stably support the carton and reduce the weight of the support frame 1.

[0041] In some embodiments, the support member is height-adjustably connected to the annular frame 11, meaning there is a gap between the support frame 12 and the annular frame 11, and the gap between the support frame 12 and the annular frame 11 is adjustable to adapt to different handling scenarios. Specifically, the support frame 12 and the annular frame 11 are connected by a fastening assembly, which includes a fastening screw 14 and locking nuts 15. The fastening screw 14 extends vertically, with one end connected to the annular frame 11 and the other end connected to the support frame 12. Two locking nuts 15 are provided on the fastening screw 14, one locking nut 15 located on the upper side of a crossbar of the support frame 12, and the other locking nut 15 located on the lower side of the same crossbar. When adjustment is required, the locking nuts 15 are loosened, the fastening screw 14 is rotated to move the support frame 12 to the appropriate position, and then the two locking nuts 15 are tightened, making adjustment convenient and flexible.

[0042] In this example, the drive assembly is located below the support frame 1. The drive assembly includes a bracket 3, a transmission chain, and a drive motor 2. The bracket 3 is set on the ground, and the transmission chain is set on the bracket 3. The bracket 3 has a space to accommodate the transmission chain. The transmission chain is set in a horizontal direction, and the drive motor 2 is connected to the transmission chain.

[0043] Connecting component 4 is mounted on the annular frame 11 and is used to connect the annular frame 11 to the drive chain. The annular frame 11 facilitates connection to the drive chain and also reduces overall weight. Connecting component 4 facilitates connection between the carrier frame 1 and the drive chain. With the drive motor 2 driving the drive chain, the carrier frame 1 can operate stably, ensuring stable operation of the paper tray and preventing it from detaching from the carrier frame 1. After the pallet carrying multiple cartons is placed on the carrier frame 1, it is driven by the drive motor 2 and transported to the factory exit. Then, a lifting mechanism transfers the pallet to a transport vehicle, improving operational efficiency and reducing manpower.

[0044] The transmission chain in this example includes a driving sprocket, a driven sprocket 7, and a chain 6. The drive shaft of the drive motor 2 is connected to the driving sprocket. The chain 6 includes chain plates 611, pins, and rollers. The chain plates 611 include inner chain plates and outer chain plates.

[0045] In some embodiments, the connecting assembly 4 includes an upper plate 41, a lower plate 42, a connector 43, and a fastener 44. The upper plate 41 and the lower plate 42 are respectively disposed on the upper and lower sides of the annular frame 11. Both the upper plate 41 and the lower plate 42 are horizontal plates. The fastener 44 connects the upper plate 41 and the lower plate 42. The fastener 44 is preferably a bolt and nut assembly. The connector 43 is disposed on the side of the lower plate 42 away from the upper plate 41. The connector 43 is used to connect the annular frame 11 of the support frame 1 to the transmission chain. The support frame 1 is connected to the transmission chain through the connecting assembly. The movement of the transmission chain drives the movement of the support frame 1, resulting in good stability.

[0046] See Figure 5 and Figure 6 The connector 43 is elongated and extends vertically. It has a through hole 433 for the pin of the transmission chain to pass through, thus achieving a stable connection between the connector 43 and the chain. In a preferred embodiment, two connectors 43 are provided. The transmission chain includes two parallel and connected chains. The connectors 43 correspond one-to-one with the chains and are connected, making the connection between the support frame 1 and the transmission chain more robust, and consequently, making the movement of the support frame 1 more stable.

[0047] In this example, four fasteners 44 are preferably provided, and the four fasteners 44 are respectively arranged around a crossbar of the annular frame 11, which can firmly connect the annular frame 11 of the support frame 1 to the transmission chain. For different sizes of annular frame 11, the space formed between the four fasteners 44 is larger than the width of a crossbar of the annular frame 11. To prevent the support frame 1 from shaking, the device also includes a connecting plate. The connecting plate is located outside the annular frame 11, between the upper plate 41 and the lower plate 42, and between the fasteners 44 and a crossbar of the annular frame 11, so as to limit the shaking of the support frame 1.

[0048] In other implementations, see Figure 7 The connector 43 includes a first connecting part 431 and a second connecting part 432. Both the first connecting part 431 and the second connecting part 432 extend in a vertical direction. The first connecting part 431 connects the lower plate 42 and one end of the second connecting part 432. The other end of the second connecting part 432 is connected to a chain plate 611 of the transmission chain. The second connecting part 432 is located on the inner side of the chain.

[0049] The device also includes a transmission chain adjustment assembly 5, which is connected to the driven sprocket 7. The transmission chain adjustment assembly 5 is used to adjust the chain. The transmission chain adjustment assembly 5 includes an adjustment plate, an adjustment screw 53, and an adjustment nut 54. The adjustment plate includes a first plate 51 and a second plate 52 perpendicularly connected to the first plate 51. The first plate 51 and the second plate 52 are L-shaped. The adjustment plate is located on the outside of the bracket 3. The first plate 51 of the adjustment plate is connected to the roller shaft of the driven sprocket 7. An elongated opening 511 is provided on the first plate 51 of the adjustment plate. A fixing member passes through the opening to connect the adjustment plate and the bracket 3. The adjustment screw 53 passes through the bracket 3 and is connected to the second plate 52 of the adjustment plate. The axial direction of the adjustment screw 53 is parallel to the direction of movement of the transmission chain, and the axial direction of the adjustment screw 53 is consistent with the extension direction of the opening 511. An adjustment nut 54 is provided on the adjustment screw 53.

[0050] A protruding plate 31 is provided on the side of the bracket 3. The protruding plate 31 is opposite to and parallel to the second plate 52. The protruding plate 31 and the second plate 52 are arranged in parallel. An adjusting screw 53 passes through the protruding plate 31 and the second plate 52. Two adjusting nuts 54 are provided on the adjusting screw 53 located between the protruding plate 31 and the second plate 52. One adjusting nut 54 is provided on the adjusting screw 53 located on the side of the protruding plate 31 away from the second plate 52. When the adjusting screw 53 does not need to be adjusted, the two adjusting nuts 54 abut against the side of the protruding plate 31 facing the second plate 52 and the side of the second plate 52 facing the protruding plate 31, respectively. The other adjusting nut 54 abuts against the side of the protruding plate 31 away from the second plate 52.

[0051] The specific implementation method of adjusting the chain through the transmission chain adjustment assembly 5 is as follows: loosen the adjusting nut 54 and the fixing part on the adjusting screw 53, rotate the adjusting screw 53 to drive the adjusting plate to move, and the movement of the adjusting plate drives the drive sprocket to move, so as to adjust the tension of the chain.

[0052] In some embodiments, the device further includes a bearing housing 8, which is connected to the bracket 3. The bearing 81 inside the bearing housing 8 is connected to the drive shaft of the drive motor 2. By providing the bearing housing, the drive motor 2 can drive the drive sprocket more stably.

[0053] In some embodiments, the device further includes a guide assembly, which includes a guide rail and a guide member. The guide rail extends in a direction parallel to the paper tray conveying direction. The guide member is movably mounted on the guide rail and is connected to the bottom of the support frame 1. The guide member can be a slider or a guide wheel. An extension member 17 is provided at the bottom of the support frame 1 and is connected to the guide member, so that the support frame 1 moves smoothly without deviation and has better stability, preventing the paper tray on the support frame 1 from falling off the support frame 1.

[0054] The device also includes a frequency converter, which controls speed regulation, forward rotation, reverse rotation, and precise positioning.

[0055] The advantages of the carton conveying device provided by this utility model are as follows: by setting a connecting component, it is easy to connect the carrier frame and the transmission chain. When the drive motor drives the transmission chain to move, the carrier frame can operate stably to ensure the stable operation of the paper tray and prevent the paper tray from falling off the carrier frame; the setting of the annular frame facilitates the connection between the annular frame and the transmission chain, and can also reduce the overall weight; it greatly improves work efficiency, avoids equipment damage, reduces enterprise maintenance costs, and also reduces the safety risks of personnel maintenance; multiple devices can be set up to reduce manual use and save labor costs.
