[0038] The roller 2 is rotatably mounted inside the mounting frame 1. Above the roller 2 are two housings 3 for positioning the cardboard in use and cooperating with the roller 2 to transport the cardboard.

[0039] There are two adjustment components, which are symmetrically installed on the top of the mounting frame 1. Both adjustment components are provided with connecting components on their sides for moving along the length direction of the roller shaft 2 in the use state.

[0040] The connecting post 4 is located at the bottom of the connecting plate 5 and one end is inserted into the inner side of the housing 3 and threadedly connected to the housing 3. The installation rotation direction of the housing 3 is arranged to match the working rotation direction of the housing 3 to prevent the housing 3 from falling off during use. The other end of the connecting post 4 is provided with a limiting component for movably connecting the connecting post 4 and the connecting plate 5 in the use state.

[0041] In this embodiment, one end of the connecting post 4 is threaded to the inner side of the housing 3, and the limiting component movably connects the connecting post 4 to the connecting component. At the same time, the connecting component is installed on the mounting frame 1 and the adjusting component, so that the housing 3 is positioned by the cooperation of the connecting post 4, the connecting component, and the limiting component, so that the housing 3 cooperates with the roller 2 to transport the cardboard. The adjusting component drives the connecting plate 5 to move along the length direction of the roller 2, so that the distance between the two connecting plates 5 and the distance between the two housings 3 are adjusted, so that the housing 3 cooperates with the roller 2 to transport cardboard of different widths. At the same time, by reversing the housing 3 on the connecting post 4, the size of the housing 3 can be changed, so that the housing 3 can press and transport cardboard of different thicknesses, and the replacement of the housing 3 is relatively convenient and quick.

[0042] Example 2

[0043] like Figure 1-2 As shown, the present invention proposes a wheeled cardboard conveying device. Compared with the first embodiment, the difference in this embodiment is that the adjusting component includes an internally threaded tube 8, a lead screw 9, and a motor 10.

[0044] The lead screw 9 is rotatably mounted on the top of the mounting bracket 1 via a bearing seat and its end extends toward the side of the mounting bracket 1.

[0045] The internally threaded tube 8 is sleeved on the outside of the lead screw 9 and threadedly connected to the lead screw 9, and its side is connected to the connecting assembly;

[0046] The motor 10 is mounted on the side of the mounting bracket 1 and is connected to the lead screw 9 for transmission.

[0047] In this embodiment, the motor 10 starts the drive screw 9 to rotate at the top of the mounting frame 1, and connects it to the connecting assembly through the internal threaded tube 8, so that the screw 9 drives the internal threaded tube 8 to move along the length direction of the screw 9, and the internal threaded tube 8 adjusts the position of the housing 3 through the connecting plate 5, so that paperboards of different widths are conveyed on the roller 2.

[0048] Example 3

[0049] like Figure 2-3 As shown, the present invention proposes a wheeled cardboard conveying device. The difference between this embodiment and the first embodiment is that the connecting component includes a connecting plate 5 and a ball bearing 13.

[0050] The connecting plate 5 is installed on the side of the internally threaded pipe 8 and extends to the top of one end of the mounting bracket 1, with the lower end face being arc-shaped.

[0051] There are multiple balls 13, which are rotatably installed on both sides of the bottom end of the connecting plate 5 and arranged at equal angles according to the center of the arc of the lower end face of the connecting plate 5. The balls 13 are rotatably connected to the connecting column 4 and the limiting component respectively.

[0052] In an optional embodiment, a slide rail 11 is provided on the top side of the mounting bracket 1 and below the lead screw 9, and a slide groove 12 is provided on one side of the connecting plate 5, with the slide rail 11 and the slide groove 12 arranged to match each other in size.

[0053] In this embodiment, the ball bearings 13 are arranged at equal angles to the center of the arc of the lower end face of the connecting plate 5, and the ball bearings 13 are positioned between the connecting column 4 and the limiting component. The connecting column 4 and the limiting component are movably connected to the connecting plate 5 through the ball bearings 13. The connecting column 4 and the limiting component rotate at the bottom end of the connecting plate 5 through the ball bearings 13 and are connected to the internal threaded tube 8 through the connecting plate 5. The connecting plate 5 is slidably connected to the mounting bracket 1 through the cooperation of the sliding groove 12 and the sliding rail 11. The connecting plate 5 limits the rotation of the internal threaded tube 8, and when the internal threaded tube 8 moves, it drives the connecting plate 5 to move synchronously, so that the connecting column 4 and the limiting component move synchronously, thereby adjusting the position of the housing 3. This makes the position adjustment of the housing 3 more convenient and quick.

[0054] Example 4

[0055] like Figure 3-4 As shown, the present invention proposes a wheeled cardboard conveying device. Compared with the first embodiment, the difference in this embodiment is that the connecting column 4 includes an external threaded joint 41, a column body 42, and a connecting block 44.

[0057] The column 42 is installed at one end of the connecting block 44 and inserted into the inside of the housing 3, and is arranged coaxially with the connecting block 44;

[0058] The external threaded connector 41 is installed at one end of the column 42 and inserted into the inner side of the housing 3, and is arranged coaxially with the column 42.

[0059] In this embodiment, by setting an external threaded joint 41 at one end of the column 42 and wrapping the shell 3 around the outside of the column 42 and simultaneously sleeved on the outside of the external threaded joint 41, a step is formed between the two ends of the shell 3, so that the shell 3 cooperates with the roller 2 through the step to transport the paperboard.

[0060] Example 5

[0061] like Figure 4 As shown, the present invention proposes a wheeled cardboard conveying device. The difference between this embodiment and the first embodiment is that the housing 3 includes a connecting pipe 31 and a sleeve 32.

[0062] The connecting pipe 31 wraps around the outside of the column 42 and extends towards the external threaded joint 41;

[0063] The sleeve 32 is provided at one end of the connecting pipe 31 and is sleeved on the outside of the external threaded joint 41.

[0064] In an optional embodiment, a threaded hole 33 is provided in the middle of the sleeve 32. When the sleeve 32 and the external threaded connector 41 are installed together, the external threaded connector 41 is accommodated in the threaded hole 33. This is used to quickly separate or connect the sleeve 32 and the external threaded connector 41 during use, so that the outer dimensions of the sleeve 32 can be changed, thereby adapting the outer dimensions of the sleeve 32 to cardboard of different thicknesses.

[0065] In this embodiment, by wrapping the connecting pipe 31 around the outside of the column 42, the outside of the connecting pipe 31 is made to roll and connect with the roller 2, and the sleeve 32 is threaded to the external threaded joint 41 through the threaded hole 33, so that a step is formed between the connecting pipe 31 and the sleeve 32, and the cardboard is conveyed in the step. At the same time, the disassembly and assembly of the connecting pipe 31 and the external threaded joint 41 are more convenient and quick, and the replacement of the outer dimension of the sleeve 32 is more convenient.

[0066] Example 6

[0067] like Figure 3-4 As shown, the present invention proposes a wheeled cardboard conveying device. The difference between this embodiment and the first embodiment is that the limiting component includes a limiting plate 6 and a bolt 7.

[0068] The limiting plate 6 is located at the other end of the connecting block 44 and is placed coaxially with the connecting block 44, and its outer diameter is the same as the outer diameter of the column 42.

[0069] Bolt 7 is located on the side of the limiting plate 6 and penetrates the limiting plate 6 to be inserted into the middle of the column 42.

[0070] In an optional embodiment, a locking block 14 is provided on the other side of the limiting plate 6, and a locking groove 43 is provided in the middle of the connecting block 44. When the limiting plate 6 and the connecting block 44 are installed together, the locking block 14 is accommodated in the locking groove 43.

[0071] In an optional embodiment, a connecting groove 15 is provided on the other end face of the column 42 and the other side of the limiting plate 6. The connecting grooves 15 on the column 42 and the limiting plate 6 are arranged symmetrically, and one end of the bolt 7 is located inside the connecting groove 15.

[0072] In this embodiment, the limiting plate 6 is installed on the other end of the connecting block 44 by bolts 7, so that the limiting plate 6 and the column 42 are connected as one piece. A connecting groove 15 is provided on the other end face of the column 42 and the other side of the limiting plate 6. The connecting groove 15 places the ball bearing 13 on the side of the connecting plate 5. The cooperation between the ball bearing 13 and the connecting groove 15 installs the column 42 and the limiting plate 6 on the bottom end of the connecting plate 5. At the same time, a locking block 14 is provided on the side of the limiting plate 6, and a locking groove 43 is provided in the middle of the connecting block 44 to cooperate with the locking block 14. The cooperation between the locking groove 43 and the locking block 14 limits the rotation of the limiting plate 6 and prevents the limiting plate 6 from falling off during rotation.

[0073] In this invention, the connecting block 44 is placed at the bottom of the connecting plate 5, and the ball bearing 13 on one side of the connecting plate 5 is located in the connecting groove 15 of the column 42 cross-section. Simultaneously, a bolt 7 is inserted into the column 42 through the limiting plate 6, connecting the limiting plate 6 to the connecting block 44. The limiting plate 6 is then rotated and limited by the slot 43 and the locking block 14, making the limiting plate 6 and the column 42 a single unit. The ball bearing 13 on the other side of the connecting plate 5 is placed in the connecting groove 15 on the other side of the limiting plate 6, allowing the column 42 and the limiting plate 6 to roll and connect with the ball bearing 13 through the connecting groove 15. The sleeve 32 is then fitted onto the outside of the external threaded joint 41 through the threaded hole 33, and the connecting tube 31 wraps around the outside of the column 42, connecting the connecting tube 31 to the roller shaft. 2. A rolling connection is established, and the roller shaft 2 is engaged with the step between the connecting pipe 31 and the threaded hole 33 to enable the paperboard to be conveyed. The motor 10 starts the drive screw 9 to rotate at the top of the mounting frame 1, and connects to the connecting assembly through the internal threaded pipe 8. The screw 9 drives the internal threaded pipe 8 to move along the length of the screw 9, and the internal threaded pipe 8 adjusts the position of the housing 3 through the connecting plate 5, so that paperboard of different widths can be conveyed on the roller shaft 2. The sleeve 32 is connected to the external threaded joint 41 through the threaded hole 33. The sleeve 32 is reversed on the external threaded joint 41 to separate the sleeve 32 from the external threaded joint 41 and change its size. The sleeve 32 and the external threaded joint 41 are then recombined to realize the conveying of paperboard of different thicknesses.

[0074] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
