[0002] Corrugated board, also known as corrugated paperboard, is formed by bonding at least one layer of corrugated paper and one layer of liner board paper, and has high mechanical strength, and can withstand collisions and drops during handling. It is mainly used for manufacturing cartons, the sandwich of cartons, and other packaging materials for fragile goods; when processing corrugated board, it is necessary to print its surface according to actual needs. During the printing process, after the printing roller contacts the corrugated board, powder scraps, fluff, and other sundries on the surface of the corrugated board will enter the recycled ink. Therefore, to avoid waste, when this recycled ink is reused, it will seriously affect the printing quality. Moreover, when the ink is recycled, the overall temperature of the ink is likely to change, resulting in a change in its adhesion due to the change in the ink temperature, causing different thicknesses of the ink adhered to the printing roller, and thus resulting in differences in the ink amount printed on the cardboard by the subsequent printing roller, causing problems with color differences in the printed pattern; to solve the above problems, it is necessary to develop a corrugated board printing ink circulation device that can perform temperature control and adjustment, has good filtration effect, and is convenient for cleaning operation.

Detailed implementation manners

[0014] The following further describes the present utility model in conjunction with the attached drawings.

[0015] Embodiment: As shown in Figure 1 , Figure 2 , Figure 3 , a corrugated cardboard printing ink circulation device includes a treatment tank 1, a heating jacket 2, and a buffer filtration tank 3. The treatment tank 1 is generally cylindrical, and both ends of its lower surface are fixedly provided with bases 11. A stirring shaft 12 is vertically rotatably penetrated through the center of the upper surface. Ink inlet pipes 13 and an ink outlet pipe 14 are vertically fixedly penetrated through both sides of the upper surface respectively. The upper end of the stirring shaft 12 is externally connected to a rotating motor 15, and the lower end is located inside the treatment tank 1, and a plurality of stirring blades 16 are evenly arranged on both sides. The lower end of the ink outlet pipe 14 is located at the bottom end inside the treatment tank 1 and is connected to a pumping assembly. The heating jacket 2 is generally annular and is fixedly sleeved on the outer end of the treatment tank 1, and an electric heating wire 21 is wound inside the heating jacket 2. The buffer filtration tank 3 is generally cylindrical, and an inlet 31 is vertically communicated with the center of its upper surface, and an outlet 32 is vertically communicated with the center of its lower surface. A plurality of filter meshes 33 are evenly fixedly arranged inside from top to bottom. Connectors 34 are provided outside both the inlet 31 and the outlet 32, and the inlet 31 is detachably connected to the ink collection and return pipe through the connector 34, and the outlet 32 is detachably connected to the ink inlet pipe 13 at the upper end of the treatment tank 1 through the connector 34.

[0016] A cleaning pipe 17 is vertically provided at the left end of the upper surface of the treatment tank 1, and a sewage discharge pipe 18 is vertically provided at the center of the lower surface. Control valves are installed on both the cleaning pipe 17 and the sewage discharge pipe 18. The cooperation of the cleaning pipe 17 and the sewage discharge pipe 18 facilitates the cleaning operation of the inside of the treatment tank 1. An electronic thermometer 19 is vertically provided at the outer end of the upper surface of the treatment tank 1. The electronic thermometer 19 facilitates the real-time detection of the temperature of the ink inside the treatment tank 1. A transparent observation frame 35 is vertically provided in the middle of the front end surface of the buffer filtration tank 3, and a scale is vertically provided at the side end of the transparent observation frame 35. The transparent observation frame 35 facilitates the observation of the filtration situation of the ink inside the buffer filtration tank 3, so that the buffer filtration tank 3 can be cleaned and replaced in time. The diameter of the filter holes gradually decreases from the uppermost filter mesh 33 to the lowermost filter mesh 33 inside the buffer filtration tank 3.

[0017] When the utility model is in use, first, the recycled ink is injected into the buffer filtration tank 3 through the ink receiving funnel, the ink collection reflux pipe, the connector 34 and the inlet 31.

Then, the power-on circuits of the rotary motor 15 and the heating wire 21 are turned on. By turning on the heating wire 21, the ink in the treatment tank 1 can be heated, so as to control and adjust the temperature of the ink, avoid the change of its adhesion due to the change of the ink temperature, and further avoid the difference in the amount of ink printed on the cardboard by the subsequent printing roller, resulting in the problem of color difference in the printed pattern. By rotating the rotary motor 15, the stirring blades 16 and the stirring shaft 12 can be driven to rotate, so that the ink in the treatment tank 1 can be evenly stirred by the rotation of the stirring blades 16. With this structure, the problem of inconsistent ink temperature in the treatment tank 1 can be avoided. At the same time, by setting the electronic thermometer 19, it is convenient to detect the temperature of the ink in the treatment tank 1 in real time. Finally, the ink after filtration and heating can be transported to the printing roller again through the ink outlet pipe 14 under the action of the pumping assembly for recycling.

[0018] By setting the connector 34, the detachable connection between the buffer filtration tank 3 and the ink collection reflux pipe and the ink inlet pipe 13 can be realized through the connector 34, so as to improve the convenience of replacing and cleaning the buffer filtration tank 3. By setting the cleaning pipe 17 and the sewage discharge pipe 18, the cooperation of the cleaning pipe 17 and the sewage discharge pipe 18 can facilitate the cleaning operation of the inside of the treatment tank 1. Generally, the utility model has the advantages of temperature control and adjustment, good filtration effect and convenient cleaning operation.
