It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. The specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.

As shown in fig. 1, the bulk material releasing device provided in the embodiment of the present application is used for dispersing bulk materials 8 and adding the dispersed bulk materials 8 to a papermaking apparatus, the bulk material 8 releasing system includes a feeding device 2 and a spreading device, the feeding device 2 is used for conveying the bulk materials 8 to the spreading device, and the spreading device is used for randomly spreading the bulk materials 8 in the papermaking apparatus after being dispersed. The bulk material 8 is preferably a paper sheet which is the same as or similar to the material of the produced anti-counterfeiting paper and does not influence the normal use of the anti-counterfeiting paper.

In the paper making process, firstly, cutting trees and reed grass of big trees into fragments, then putting the fragments into a large high-pressure container, adding sodium hydroxide and sodium sulfide to separate lignin from the fragments, and thus obtaining paper pulp mainly containing the lignin; then uniformly scattering the separated paper pulp on a papermaking device; then drying and compacting the moisture of the paper pulp at high temperature, carrying out calendaring by a calendaring machine, and finally further cutting the calendered paper to prepare the paper with various sizes.

In the paper production process, the pulp 7 is laid on a pulp conveying belt of papermaking equipment, the bulk materials 8 are randomly scattered on the surface of the pulp 7 through the material scattering device, and then the drying and compacting process is carried out, so that the produced anti-counterfeiting material is randomly scattered and laid with the bulk materials 8, the anti-counterfeiting paper has strong uniqueness, the copying difficulty is high, the anti-counterfeiting effect is good, the process is simple, the production efficiency cannot be influenced, meanwhile, the bulk materials 8 cannot be in the pulp 7 for a long time, and the physical properties of the anti-counterfeiting paper are prevented from changing.

In some embodiments, the bulk material 8 may also be a plastic sheet, a fabric sheet, or the like, and specifically, the bulk material 8 may be one of a paper sheet, a plastic sheet, and a fabric sheet, or a mixture of multiple (including two) materials, and at the same time, the color of the bulk material 8 may also be multiple, so as to increase the anti-counterfeiting effect.

The pulp 7 can be driven by a pulp conveying mechanism of the papermaking equipment to move, so that the automation degree is increased. Specifically, the slurry 7 is in the moving process, the bulk materials 8 fall onto the slurry 7, then the slurry 7 with the bulk materials 8 scattered continues to move forward, the bulk materials 8 fall onto the subsequent slurry 7, the production efficiency is increased, meanwhile, the phenomenon that the product is affected due to the fact that the slurry 7 at a certain position falls into too many bulk materials 8 is avoided, and meanwhile, the density of the slurry 7 falling into the bulk materials 8 can be changed by adjusting the moving speed of the slurry 7.

The material scattering device can disperse the bulk materials 8 through mechanical vibration or air flow disturbance, and the dispersed bulk materials 8 fall into papermaking equipment at random.

In some embodiments, the spreading device is a blowing device. The blowing device comprises a blower 1 and a nozzle 5, and is used for blowing the bulk material 8 out of the nozzle 5. The air volume of the blower 1 can be adjusted according to the weight or the spraying amount of the bulk materials 8, the use convenience is improved, and the anti-counterfeiting effect is improved by adjusting the air volume of the blower 1 to change the density of the bulk materials 8 scattered on the slurry 7. Specifically, when the air volume of the blower 1 is small, the blowing speed of the bulk materials 8 is slow, and the bulk materials 8 fall onto the slurry 7 in a concentrated manner; when the air volume of the blower 1 is large, the speed of blowing out the bulk materials 8 is high, and the bulk materials 8 are scattered and sprinkled on the slurry 7. Specifically, a pipeline 4 can be arranged at the air blowing port of the air blower 1, the nozzle 5 is arranged at the other end of the pipeline 4, when the air blower is used, the material is conveyed into the pipeline 4 by the feeding device 2, the bulk materials 8 in the pipeline 4 are blown out by the air blower 1, and the pipeline 4 can avoid the phenomenon that the bulk materials 8 are too dispersed and then deviate from paper pulp.

In order to avoid the phenomenon that the speed of the bulk materials 8 blown out is high, so that the bulk materials 8 are separated from the pulp 7, the resistance belt 6 is arranged on a dealer of the papermaking equipment, specifically, the resistance belt 6 is arranged above the papermaking equipment, and the resistance belt 6 is used for blocking the bulk materials 8 and enabling the blocked bulk materials 8 to fall into the papermaking equipment. The nozzle 5 and the resistance belt 6 are arranged oppositely, and the bulk materials 8 with high speed are blocked by the resistance belt 6 and fall on the slurry 7, so that subsequent workers are prevented from cleaning the waste bulk materials 8.

The resistance belt 6 comprises a driving roller, a driven roller and a conveying belt, the conveying belt is sleeved on the peripheries of the driving roller and the driven roller, and one surface of the conveying belt, which is in contact with the bulk materials 8, moves downwards along with the rotation of the driving roller.

Further optimally, the resistance bands 6 can be moved in the vertical and horizontal directions, and specifically, brackets can be provided on both sides of the resistance bands 6 to change the positions of the resistance bands 6 by moving the brackets. Wherein, the blowing direction of the bulk material 8 can be changed by changing the orientation of the nozzle 5, so as to change the angle of the bulk material 8 falling onto the slurry 7, and meanwhile, the density of the bulk material 8 falling onto the slurry 7 is changed by matching with the position of the resistance belt 6, thereby increasing the randomness of the scattering of the bulk material 8 and further increasing the anti-counterfeiting effect.

Specifically, when the nozzle 5 is adjusted upward, the density of the bulk material 8 falling onto the slurry 7 is high, and at the same time, the resistance belt 6 needs to be appropriately adjusted upward in order to avoid the bulk material 8 from being ejected too far; the nozzle 5 is gradually adjusted downwards, the density of the bulk materials 8 falling onto the slurry 7 is gradually reduced, when a certain value is reached, the density of the bulk materials 8 is gradually increased, and meanwhile, the outside of the slurry 7 sprayed by the bulk materials 8 can be effectively avoided by matching with the downward adjustment of the resistance belt 6, the structure is simple, and the use is convenient; since the pulp 7 is movable in the horizontal direction, when the resistance belt 6 is moved in the direction toward the nozzle 5, the bulk material 8 falls concentratedly below the resistance belt 6 to thereby increase the density of the bulk material 8 falling onto the pulp 7 passing therethrough, and when the resistance belt 6 is moved away from the nozzle 5, the density of the bulk material 8 is gradually decreased.

As shown in fig. 2, in order to prevent the loose materials 8 from being separated from the slurry 7, the nozzle 5 may be inclined toward the front lower side, a barrier net 51 for restricting the direction in which the loose materials 8 are spread may be provided on the outer periphery of the nozzle 5, and the direction in which the loose materials 8 are spread may be restricted by the barrier net 51. Specifically, the barrier net 51 is provided in two pieces, one of the barrier nets 51 is provided in front of the nozzle 5 in the nozzle direction, and the other of the barrier nets 51 is provided below the nozzle 5 in the nozzle direction, thereby restricting the dispersed bulk material 8 within a certain range.
