Description

Technical Field

[0001] The utility model relates to the field of paper-plastic production equipment, in particular to a multi-pulp board raw material pulping device for paper-plastic production. Background Technique

[0002] With the increasing demand for the production of paper-plastic products, more and more diverse paper-plastic products are produced and processed. The existing paper-plastic no longer meets the traditional natural color or white characteristics. By adding pulp board raw materials of different materials and going through processes such as crushing, pulping, forming, and hot pressing, a paper-plastic structure with multiple texture styles can be produced. Pulping, as the initial stage of paper-plastic pulp board raw materials, usually crushes the pulp board by hydraulic means. For example, a pulper for pulp molding processing disclosed on the Chinese Patent Network (publication number CN214245094U). When using such a device, the control motor drive member drives the rotor, and the metal blades on the rotor are used to break the paper into pulp. When the pulp is finished, the good pulp discharge port below is opened, and the good pulp flows out from the good pulp discharge port, while the coarse pulp inside will hang on the two sets of sieve plates. Subsequently, by opening the hatch, the coarse pulp on the two sets of sieve plates is cleaned, and the next operation can be carried out after the cleaning is completed.

[0003] However, for the above-mentioned disclosed patents and the pulp shredders adopted in the existing market, there are still some deficiencies: the existing method of using a single rotating blade component to cut and crush the pulp can only perform the cutting and crushing work on the pulp in the central part, and the pulp at the edge part cannot be fully cut and crushed, resulting in a relatively low quality of pulp shredding. Therefore, those skilled in the art have provided a multi-pulp board raw material pulping device for paper-plastic production to solve the problems raised in the above background technique.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-3 , the present invention provides a technical solution for a multi-pulpboard raw material pulping device for paper-plastic production: a multi-pulpboard raw material pulping device for paper-plastic production, including a pulping tank 1.

By controlling the operation of the brake motor 4, the brake shaft 9 is driven to rotate, and the transmission gear 14 is driven to rotate synchronously. The differential meshing transmission of the transmission gear 14 and the differential gear 15 is utilized to drive the crushing shaft 11 to rotate synchronously at a high speed, so as to promote the linkage operation of the components on the shaft, and perform a dynamic stirring, rotary cutting and crushing process on the paddle raw material and water.

[0025] A material-shifting paddle 10 is arranged on the upper half of the shaft of the brake shaft 9, facing the interior of the crushing chamber 7, and a stirring paddle 13 is arranged on the lower half of the shaft of the brake shaft 9, facing the interior of the liquid chamber 8. The material-shifting paddle 10 is a straight paddle plate structure, and the stirring paddle 13 is a rotary push paddle structure. When the brake shaft 9 rotates, on the one hand, it drives the material-shifting paddle 10 of the straight paddle plate structure to rotate, thereby promoting the stirring of water and pulp board raw materials in the crushing chamber 7, so that the water and pulp board raw materials are fully mixed and pulverized; on the other hand, it drives the stirring paddle 13 of the rotary push paddle structure to rotate, thereby promoting dynamic stirring of the finished slurry in the liquid chamber 8 to avoid sedimentation and stratification.

[0027] A plurality of groups of feeding ports 2 are arranged along the circumference of the upper end of the pulping tank 1, and a discharge port 3 is arranged at the bottom of the pulping tank 1. Pulp board raw materials and water are fed into the pulping tank 1 in a quantitative ratio through the feeding port 2 to carry out the pulping process, and after the pulping of the pulp board raw materials is completed, the pulped pulp board raw materials are discharged through the discharge port 3.

[0028] The working principle of the utility model is as follows: when the pulping device is used to carry out the pulping process on the multi-paddle raw materials, the multi-paddle raw materials, such as white bamboo pulp, white sugarcane pulp, and natural straw pulp, can be put into the pulping tank 1 at a ratio of 10%, 80%, and 10%, and fall into the crushing chamber 7 for pulping, and a rated amount of water is simultaneously put into the pulping tank 1 as a hydraulic crushing medium;

[0029] Then, control the braking motor 4 to work, drive the braking shaft 9 to rotate, drive the transmission gear 14 to rotate synchronously, utilize the differential meshing transmission between the transmission gear 14 and the differential gear 15, drive the crushing shaft 11 to rotate synchronously at high speed.

While the crushing shaft 11 rotates, drive the crushing cutter 12 to rotate, and perform the rotary cutting and pulping process on the pulp board raw materials in dynamic stirring;

[0030] And while pulping, by controlling the circulating water pump 51 to work, utilize the liquid suction pipe 52 to circularly suction the finished liquid in the liquid chamber 8, and circularly suck the finished liquid back to the crushing chamber 7 through the return pipe 53, forming a pulping state with an up-and-down dynamic flow form, pumping the slurry to flow dynamically. And while the slurry flows dynamically, utilize the separation and filtration of the separation filter plate 6 to filter the qualified slurry, isolate the unqualified pulp board raw materials, and filter them after crushing. Then, in this way, perform a dynamic and comprehensive pulping process on the pulp board raw materials. Then, the slurry after pulping is discharged through the discharge port 3, and through processes such as refining, forming, and hot pressing and shaping, produce paper-plastic products with surface texture and color.
