Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0025] As Figures 1-4 shown, the present utility model has the following specific embodiments.

[0026] Embodiment:

[0027] A corrugated paper positioning and indentation device includes a U-shaped frame 1. Inside the U-shaped frame 1, there are two gear-shaped indentation rollers 2 that are meshed and connected. The gear-shaped indentation rollers 2 are rotationally connected to the U-shaped frame 1 through the provided rotating rods 21. At the top of the U-shaped frame 1, two fixed frames 4 are fixedly connected. A corrugated paper roll 6 is erected between the two fixed frames 4. The corrugated paper roll 6 is erected on the erection slots 41 opened in the fixed frames 4 through the provided shaft rods. A guide frame 5 is fixedly connected between the two fixed frames 4, and the guide frame 5 is located directly above the middle of the two gear-shaped indentation rollers 2.

[0028] By adopting the above technical solution, when using the device, first, the corrugated paper roll 6 is erected on the two fixed frames 4. One end of the corrugated paper on the corrugated paper roll 6 can pass through between the two pressing rollers 53 and then extend into the space between the two gear-shaped indentation rollers 2. Then, the motor 3 is turned on to drive the two gear-shaped indentation rollers 2 to rotate relative to each other. The two mutually rotating gear-shaped indentation rollers 2 can pull the extended corrugated paper for indentation and transportation. Among them, the two pressing rollers 53 can flexibly press the transported corrugated paper to keep it taut during transportation and prevent wrinkles from appearing during the corrugated paper indentation.

[0029] Specifically, L-shaped support plates 11 are fixedly connected to both sides of the U-shaped frame 1.

[0030] By adopting the above technical solution, the provided L-shaped support plates 11 can position and support the U-shaped frame 1.

[0031] Specifically, a motor 3 is fixedly connected to the top of the L-shaped support plate 11. The output shaft of the motor 3 is fixedly connected with a second pulley 31. One end of the rotating rod 21 is fixedly connected with a first pulley 22, and the second pulley 31 and the first pulley 22 are synchronously driven through the provided transmission belt 32.

[0032] By adopting the above technical solution, the provided motor 3 can drive the second pulley 31 to rotate. The second pulley 31 can drive the first pulley 22 to synchronously transmit power through the transmission belt 32. The first pulley 22 can drive the gear-shaped indentation roller 2 to rotate through the rotating rod 21, and then can drive two mutually meshed and connected gear-shaped indentation rollers 2 to rotate.

[0033] Specifically, both ends inside the guide frame 5 are fixedly connected with sliding rods 51. An actuating rod 52 is movably connected to the sliding rods 51. An extrusion roller 53 is rotatably connected to the actuating rod 52. Both ends of the sliding rods 51 are fixedly connected with springs 54, and one end of each spring 54 is fixedly connected to the actuating rod 52.

[0034] By adopting the above technical solution, the two provided extrusion rollers 53 can be mutually attached inside the guide frame 5. Since the actuating rod 52 rotatably connected to the extrusion roller 53 can slide on the sliding rod 51, and the spring 54 connected to the sliding rod 51 can be squeezed between the guide frame 5 and the actuating rod 52, the compressed spring 54 can generate a reaction force, so that the extrusion rollers 53 rotatably connected to the two actuating rods 52 are mutually and flexibly extruded, and then the corrugated paper passing through can be flexibly extruded.

[0035] Specifically, the two extrusion rollers 53 are located directly above the two gear-shaped indentation rollers 2.

[0036] By adopting the above technical solution, the corrugated paper conveyed by the corrugated paper roll 6 passes through the two extrusion rollers 53. The two extrusion rollers 53 flexibly press the passing corrugated paper, and then input it between the two gear-shaped indentation rollers 2 for indentation.

[0037] Specifically, there is a gap between the two gear-shaped indentation rollers 2.

[0038] By adopting the above technical solution, the gap provided between the two gear-shaped indentation rollers 2 enables the corrugated paper to pass through, so that the two mutually meshed gear-shaped indentation rollers 2 extrude and form the corrugated paper.
