[0022] In order to make the purpose, technical solution and effect of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] See Figure 1 , Figure 1This is a structural schematic diagram of a multi-station rotary corrugated cardboard single-facer provided by the utility model, which includes a machine base 8, a central axis 1 is provided in the middle of the machine base 8, and the upper part of the machine base 8 is located at the same vertical direction as the central axis 1 at position 0; a corrugating roller mounting disk 2 is provided at the central axis 1 and is arranged toward one side of the machine base 8; a plurality of corrugating roller groups are circumferentially spaced and arranged on the corrugating roller mounting disk 2, with the axis of the central axis 1 as the center line; a pressure roller 7 is provided on the machine base 8 and is arranged along the same center line as the central axis 1 in the vertical direction, and a gap is left between the pressure roller 7 and the corrugated roller group to accommodate a first corrugated cardboard driving device 12 provided on the machine base 8 and engaged with the corrugated roller group.

[0024] It should be noted that, in this embodiment, the multiple corrugated roller groups include a first corrugated roller group 3, a second corrugated roller group 4, a third corrugated roller group 5, and a fourth corrugated roller group 6, and the specifications of the corrugated rollers in each group are different to adapt to corrugated cardboards of different specifications and realize convenient adjustment of the corrugated rollers.

[0025] When in use, first determine the corresponding corrugating roller group according to the different specifications of corrugated cardboards to be produced, and then rotate the corrugating roller mounting plate 2 to adjust the corrugating roller group of the required specifications to 0 position. By installing multiple corrugating roller groups of different specifications on the corrugating roller mounting plate 2, when facing the production of corrugated cardboards of different specifications, the corrugating roller group of the required specifications can be adjusted to 0 position by rotating the corrugating roller mounting plate 2, so that the production specifications can be adjusted and changed at any time without the need to disassemble and replace the corrugating rollers. While improving the production efficiency of the corrugated cardboard, it also saves a lot of steel raw materials, saving more than 20% of raw materials.

[0026] At this time, the pressure roller 7 is relative to the corrugated roller group, and the gap left between the pressure roller 7 and the corrugated roller group is for the corrugated cardboard to pass through. After the first driving device 12 is started, the corrugated roller group rotates, and the teeth on the corrugated roller and the elastic material at both ends of the pressure roller are rolled into a gear meshing state. The elastic deformation of the elastic material is utilized to drive the pressure roller 7 to rotate. The requirement of synchronous rotation with the corrugated roller is achieved without the need for a speed regulating device of the pressure roller 7 motor. The complex motor synchronization adjustment can achieve the synchronization requirement without adjustment, which is convenient and fast.

[0027] Among them, a second drive device 11 is also provided. The second drive device 11 is arranged on the machine base 8, and the drive end is connected to the central shaft 1. In the embodiment of the present utility model, the second drive device 11 adopts a drive motor for rotation adjustment, which can increase the speed of adjusting the specifications of the corrugated roller group and further improve the production efficiency of corrugated cardboard.

[0028] In addition, the corrugating roller group includes a first corrugating roller and a second corrugating roller. The first corrugating roller is connected to the corrugating roller mounting disk 2 through the first roller shaft 9 and is clamped with the first drive device 12. The second corrugating roller is connected to the corrugating roller mounting disk 2 through the second roller shaft 10, and the first drive device 12 adopts a driving motor. A slot-type connection method can be adopted at the connection between the driving end of the motor and the first roller shaft 9. When replacing, it is only necessary to move the motor to release the connection with the corrugating roller group. After replacement, it can be clamped in the same way, so that only one set of motors is needed to control the rotation of all corrugating roller groups, reducing resource consumption.

[0029] In this embodiment, the outer ring of the pressure roller 7 is coated with a silicone layer. By providing the silicone layer, the friction between the pressure roller 7 and the corrugated cardboard can be enhanced to ensure the synchronous rotation of the pressure roller 7 and the corrugated roller.

[0030] Those skilled in the art will readily conceive of other embodiments of the present invention after considering the specification and practicing the solutions disclosed herein. This invention is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein. The description and examples are to be considered as exemplary only; the true scope and spirit of the invention are indicated by the claims.
