[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides two technical solutions:

[0023] like Figures 1-2The first embodiment is shown: a pulping device for corrugated cardboard production, including a pulping cylinder 1, a placement box 2 fixedly installed at the bottom of the pulping cylinder 1, an auger 3 rotatably installed at the bottom center of the inner cavity of the pulping cylinder 1, a plurality of first shredders 4 for shredding waste paper evenly fixedly installed on the outer wall of the auger 3, a water spraying mechanism 5 fixedly installed at the top of the auger 3, a toothed ring 6 fixedly sleeved on the outside of the auger 3 located inside the placement box 2, a servo motor 7 fixedly installed on the bottom right side of the placement box 2, a gear 8 fixedly sleeved on the outside of the output shaft of the servo motor 7, a flexible hose 9 fixedly installed at the bottom of the placement box 2 located below the auger 3, a plurality of second shredders 10 evenly fixedly installed on the lower inner wall of the pulping cylinder 1, guide plates 11 fixedly installed on both the left and right sides of the top of the inner cavity of the pulping cylinder 1, two shredding rollers 12 for shredding raw material waste paper for corrugated cardboard production rotatably installed between the front and rear walls of the inner cavity of the pulping cylinder 1, and a plurality of shredding teeth 13 fixedly installed from front to back on the middle of the side of the two guide plates 11 that are close to each other.

[0024] Through the cooperation of the L-shaped tube 52, the arc-shaped tube 53, the first nozzle assembly 54, and the second nozzle assembly 55, the initially crushed waste paper falls into the pulping cylinder 1. After passing through the four L-shaped tubes 52, the waste paper is sprayed with water in a targeted manner to achieve pre-wetting. The pre-wetted waste paper continues to fall and drops into the bottom of the inner cavity of the pulping cylinder 1. Then, it is sprayed with water from the second nozzle assembly 55 to wet it again, so that every area of ​​the waste paper surface can be evenly sprayed with water, fully wetting the waste paper, improving the softening effect, and ensuring the subsequent pulping effect.

[0025] like Figures 3-5The second embodiment is shown, the main difference from the first embodiment being: a pulping device for corrugated cardboard production, wherein the bottom of the auger 3 penetrates the bottom of the pulping cylinder 1 and is rotatably connected to the bottom of the inner cavity of the placement box 2, the output shaft of the servo motor 7 penetrates the bottom of the placement box 2 and is rotatably connected to the bottom of the pulping cylinder 1, the gear 8 meshes with the gear ring 6, the two guide inclined plates 11 are symmetrically arranged, the two crushing rollers 12 are located between the two guide inclined plates 11, the water spraying mechanism 5 includes a connecting block 51, the connecting block 51 is fixedly connected to the top of the auger 3, four L-shaped tubes 52 are evenly fixedly arranged around the side wall of the connecting block 51, the top of the four L-shaped tubes 52 on the side away from each other are fixedly connected to an arc-shaped tube 53, and a number of first nozzle assemblies 54 are fixedly arranged on the side of the four L-shaped tubes 52 that are close to each other, and the bottom of each arc-shaped tube 53 is fixedly arranged with... There are several second nozzle assemblies 55. The first nozzle assembly 54 and the second nozzle assembly 55 have the same structure. Each first nozzle assembly 54 includes a water spray pipe 541. The water spray pipe 541 is fixedly connected to the side wall of the L-shaped pipe 52. A mesh semicircular cover 542 is fixedly installed at the end of the water spray pipe 541 away from the L-shaped pipe 52. A support rod 543 is rotatably passed through the middle of the mesh semicircular cover 542. The end of the support rod 543 away from the mesh semicircular cover 542 is rotatably connected to the inner wall of the L-shaped pipe 52. Several arc-shaped blades 544 located inside the L-shaped pipe 52 are evenly fixedly installed around the outside of the support rod 543. An arc-shaped brush 545 is fixedly installed at the end of the support rod 543 away from the L-shaped pipe 52. The inside of the auger 3 and the connecting block 51 are hollow. The inside of the auger 3, the connecting block 51, the L-shaped pipe 52, the arc-shaped pipe 53 and the hose 9 are in a connected state.

[0026] Through the cooperation of the mesh semicircular cover 542, support rod 543, arc blade 544 and arc brush 545, the impact energy of the water flow drives the arc brush 545 to rotate, which promptly sweeps the surface of the mesh semicircular cover 542, preventing waste paper from adhering to the mesh semicircular cover 542 and causing blockage, and ensuring that the water flow is normally sprayed out through the water spray pipe 541.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0028] In operation, both crushing rollers 12 are driven by external motors and rotate in opposite directions. Waste paper used in corrugated cardboard production is fed into the guide plate 11. The waste paper is initially crushed by the interaction of the two crushing rollers 12 and the crushing teeth 13. The initially crushed waste paper continues to fall into the pulping cylinder 1. It then passes through four L-shaped pipes 52. Because the hose 9 is connected to an external water source, water is drawn into the L-shaped pipes 52 and the arc-shaped pipe 53 through the hose 9, the auger 3, and the connecting block 51 by an external pump. Finally, it is sprayed out through the first nozzle assembly 54 and the second nozzle assembly 55. The waste paper passing through the four L-shaped pipes 52 is pre-wetted by the water sprayed from the first nozzle assembly 54. The pre-wetted waste paper continues to fall. Driven by the servo motor 7, the four L-shaped pipes 52 rotate together with the auger 3. The falling waste paper is broken up and evenly dropped into the lower part of the inner cavity of the pulping cylinder 1. Then, it is moistened again by water sprayed from the second nozzle assembly 55, so that every area of ​​the waste paper surface is evenly sprayed with water, achieving a good softening effect. Under the rapid rotation of the auger 3 and the first shredder 4, in conjunction with the second shredder 10, the moistened waste paper is shredded. During the process, the water flows through the interior of the L-shaped tube 52 and the arc-shaped tube 53. Driven by the water flow, the arc-shaped blade 544, the support rod 543, and the arc-shaped brush 545 rotate. The rotating arc-shaped brush 545 sweeps the surface of the mesh semicircular cover 542 in time to prevent waste paper from adhering to the mesh semicircular cover 542 and causing blockage. This allows the water to flow normally through the mesh of the mesh semicircular cover 542 and ensures the normal pulping process. After pulping is completed, the sealing door at the front end of the pulping cylinder 1 is opened to discharge the material.
