Description

Technical Field

[0001] The utility model relates to the field of pulping equipment, in particular to a coarse pulping equipment for recycling corrugated core paper from waste paper. Background Art

[0002] Wastepaper recycled corrugated medium is the core paper of corrugated board made from recycled waste paper. Corrugated board is widely used in packaging and transportation. Its structure usually consists of an outer layer of face paper, an inner layer of corrugated paper core and sometimes a bottom layer of paper.

[0003] The Chinese patent with the authorization announcement number CN218690113U discloses a sea cucumber grinding device, comprising a base, a first drive motor fixed to the bottom end of the base, an inner cavity provided inside the base, a grinding cavity provided inside the top end of the base, and a grinding knife provided inside the grinding cavity. During the use of the sea cucumber grinding device, after the processed sea cucumber material is introduced into the grinding cavity through the through groove in the splash-proof cover, the grinding knife driven by the first drive motor can grind the sea cucumber material inside the grinding cavity. At the same time, during the grinding process, a splash-proof cover is fixed inside the top end of the hopper. The splash-proof cover can assist in sealing the top end of the hopper when the sea cucumber is ground. When the sea cucumber is used, it can be intercepted and dropped back for re-grinding, reducing the splashing of the sea cucumber during the grinding process, thereby solving the problem of inconvenience in grinding the sea cucumber.

[0004] However, this device still has some shortcomings: when in use, the position between the grinding knife and the grinding chamber cannot be adjusted, so it cannot meet different grinding coarseness requirements, thereby reducing the flexibility of the device. Utility Model Content

[0005] The utility model aims to solve the problem in the background art that the position between the grinding knife and the grinding chamber cannot be adjusted, and proposes a coarse grinding device for recycling corrugated core paper from waste paper.

[0006] The technical solution of the utility model is a coarse pulping device for recycling corrugated medium paper from waste paper, comprising:

[0007] Fixed frame;

[0008] a grinding box, which is arranged on a fixed frame;

[0009] A lifting assembly, which is arranged on a fixed frame and is used to adjust the height of the refining equipment in a working state;

[0010] The grinding disc is rotatably mounted on a lifting assembly and is located in the grinding box. The lifting assembly is provided with a rotating assembly for driving the grinding disc to rotate;

[0011] And a discharging component, which is arranged on the grinding box and is used to evenly discharge the slurry in the working state.

[0012] Preferably, the grinding disc is a conical disc.

[0013] Preferably, the rotating assembly comprises:

[0014] a first driving device, which is disposed on the lifting assembly;

[0015] and a mounting column connected to the first driving device, and a grinding disc connected to the other end of the mounting column.

[0016] Preferably, the lifting assembly includes:

[0017] a support column, which is arranged on the fixed frame;

[0018] a second driving device disposed on the support column;

[0019] a threaded column rotatably mounted on the support column and connected to the second drive device;

[0020] and a connecting plate which is slidably arranged on the supporting column and is threadedly connected to the threaded column. The first driving device is arranged on the connecting plate, and the mounting column passes through the connecting plate.

[0021] Preferably, the discharging assembly comprises:

[0022] a material transfer pipe passing through the grinding box;

[0023] A discharge pipe, which is arranged on the material transfer pipe;

[0024] And a spiral conveying blade is rotatably arranged on the material transfer pipe.

[0025] Preferably, the spiral conveying blades are in contact with the inner wall of the material transfer pipe.

[0026] Compared with the prior art, the present invention has the following beneficial technical effects:

[0027] By setting up the lifting assembly and the use of the grinding disc, the type and quality of waste paper vary greatly. The mechanism that can adjust the distance between the grinding disc and the grinding box allows the equipment to be adjusted according to the different characteristics of waste paper. This flexibility helps to process a variety of raw materials and improve the adaptability of the production line. BRIEF DESCRIPTION OF THE DRAWINGS
