Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of composite rust-proof paper, in particular to a paper-plastic glue bonding composite rust-proof paper and a preparation system thereof. BACKGROUND

[0002] Rust-proof paper is a kind of paper material used to prevent metal from rusting, and its base material is usually kraft paper, which is suitable for various metal materials and products. The base paper of rust-proof paper is currently mixed with bamboo pulp and wood pulp to add lignin sulfonate (to enhance moisture resistance). After paper pulp is made and polished, the basic base paper is formed. However, the amount of bamboo pulp used in rust-proof paper is relatively large.

[0003] At present, the field of biomass conversion materials is developing rapidly, and there are a variety of materials that can be used. Straw pulp is one of the most representative. During the agricultural harvest season, there are often piles of straw in the fields. These seemingly useless agricultural waste actually contains great potential value.

[0004] If straw can be reasonably used in the production process of rust-proof paper base paper, it is undoubtedly a forward-looking and environmentally friendly innovation. In this way, the proportion of traditional pulp used in the production of rust-proof paper can be significantly reduced. From the perspective of resource recycling, this achieves efficient recycling of straw materials, giving new life to straw that would otherwise be burned or discarded.

[0005] More importantly, this approach fully demonstrates its environmentally friendly characteristics. In the traditional pulp production process, there are often high energy consumption and environmental pollution problems, such as deforestation, which can damage forest ecosystems, and the production of some chemical pulp can also produce pollutants such as wastewater and exhaust gas. In contrast, using straw pulp to make rust-proof paper base paper can effectively reduce dependence on natural resources, reduce carbon emissions and pollutant emissions during production, and contribute to environmental protection, truly integrating resource conservation and environmental protection.

[0006] In addition, in the process of producing rust-proof paper, the first step is to treat the base paper, such as dust removal, and then apply the rust-proof liquid. Currently, although the application of rust-proof liquid can be completed by applying the roll, the amount of rust-proof liquid delivered to the application roll is not uniform, which also leads to uneven application of rust-proof liquid, and the rust-proof liquid needs to be further treated to make it evenly spread on the base paper, increasing the steps and equipment investment of the application work. Therefore, the present application proposes a paper-plastic glue bonding composite rust-proof paper and a preparation system thereof. SUMMARY

[0016] Preferably, the heat exchange mechanism further comprises a coiled pipe located in the VCI anti-rust liquid storage box, and hoses being mounted at both ends of the coiled pipe and connected to the air supply pipe and the air outlet pipe, respectively.

[0017] Preferably, the dust removal mechanism further comprises a dust filter box mounted in the mounting frame, the dust filter box being connected to the heating box through a pipeline, a dust filter plate being mounted in the dust filter box, a dust suction pipe being mounted on one side of the dust filter box and located below the dust filter plate, and the dust suction pipe being oppositely arranged relative to the biomass conversion material substrate.

[0018] Preferably, the transmission mechanism further comprises a transmission shaft fixedly connected coaxially with the rotating column, a linkage shaft rotatably mounted on the mounting frame, first synchronous wheels being mounted on the drive shaft and the linkage shaft, the two first synchronous wheels being connected by a first synchronous belt, gears being mounted on the linkage shaft and the rotating pipe, the two gears being engaged, second synchronous wheels being mounted on the rotating pipe and the transmission shaft, and the two second synchronous wheels being connected by a second synchronous belt.

[0019] Compared with the prior art, the present application has the following beneficial effects:

[0020] 1. Environmentally friendly and resource-saving: The use of straw pulp and wood pulp to make biomass conversion material substrates replaces part of the traditional pulp, significantly reducing the dependence on natural resources, especially reducing the cutting of trees, which is beneficial to the protection of forest ecosystems. The application of straw pulp realizes the efficient recycling of straw materials, avoids the burning or discarding of straw, reduces carbon emissions and pollutant emissions, and contributes to environmental protection.

[0021] 2. Improve the coating quality of the rust-proof liquid: The rust-proof liquid coating mechanism realizes uniform coating of the rust-proof liquid through the design of VCI rust-proof liquid storage tank, coating roller, air hole, etc. The rotating plate design in the VCI rust-proof liquid storage tank ensures equal supply of rust-proof liquid, controls the pressure between the VCI rust-proof liquid storage tank and the coating roller, and avoids uneven coating.

[0022] 3. The design of the rust-proof liquid storage tank and air hole on the coating roller allows the rust-proof liquid to be coated in a strip shape on the substrate, and the hot air discharged through the air hole accelerates the rust-proof liquid to leave the storage tank, and the use of gravity and air action allows the rust-proof liquid to be evenly spread over the entire substrate, improving the coating quality.

[0023] 4. Reduce subsequent processing steps: Due to the uniform coating of the rust-proof liquid, the subsequent step of further processing the coated rust-proof liquid to evenly spread it on the base paper is reduced, reducing production complexity and equipment investment.

[0024] 5. Dust removal and drying integration: The dust removal mechanism effectively removes dust from the surface of the biomass conversion material substrate through the design of the dust filter box and the dust suction pipe, ensuring the quality of the subsequent production of rust-proof paper. The drying mechanism uses heated air to dry the rust-proof liquid coated substrate, improving production efficiency and ensuring the drying effect of the rust-proof liquid.

[0025] 6. Energy saving and temperature control: The heating mechanism heats the air through the design of the heating box and the heating wire, and heats the rust-proof liquid through the heat exchange mechanism, keeping it at an appropriate temperature to ensure the flowability of the rust-proof liquid to meet the coating requirements. The temperature control mechanism ensures that the temperature of the air heated by the heating wire is within an appropriate range, avoiding energy waste and volatilization of the internal substances of the rust-proof liquid.

[0026] 7. Transmission mechanism optimization: The transmission mechanism realizes linkage and transmission between components through the design of synchronous wheels, synchronous belts and gears, improving production efficiency and stability. From dust removal of biomass conversion material substrates, rust-proof liquid coating, drying to pressing of each layer of material, the entire production process realizes automation and continuity, improving production efficiency and product quality.

[0027] In conclusion, the present application utilizes biomass conversion materials such as straw pulp to reduce the dependence on natural resources, reduce carbon emissions and pollution, and realize resource recycling; at the same time, the anti-rust liquid coating mechanism is innovated to ensure uniform coating and reduce subsequent processing steps; the dust removal, drying and other supporting mechanisms improve the quality of anti-rust paper and provide an environmentally friendly, efficient and high-quality solution for anti-rust paper production.

[0054] The motor is installed on the mounting frame 2 and connected with the first transmission roller 3, and the rotation of the first transmission roller 3 can drive the driving shaft 17 to rotate and supply power to the fan.

[0055] The production process of the rust-proof paper is as follows:

[0056] Biomass conversion material substrates such as Figure 1 The winding is shown in the first transmission roller 3 and the second transmission roller 13, and the fan works to make the external air enter into the dust filtering box 9 through the dust suction pipe 30, and then sequentially pass through the pipeline 11, the heating box 8, the air feeding pipe 12, the hose 35, the serpentine pipe 34, the air outlet pipe 10 and enter into the exhaust box 14.

[0057] When the air enters into the dust filtering box 9 through the dust suction pipe 30, the pipe opening of the dust suction pipe 30 is in a negative pressure state at this time, so that the dust on the surface of the biomass conversion material substrate can be removed, that is, the side needing to be coated with rust-proof water is dusted, the influence of subsequent dust on the coating of rust-proof water and subsequent pressing is reduced, and the quality of the production of the rust-proof paper is ensured.

[0058] When the air and the dust pass through the dust filtering box 9, the dust filtering plate 42 can filter the dust in the air, that is, the clean air enters into the heating box 8 through the pipeline 11, and the air can be heated through the electric heating wire 32; the heated air enters into the serpentine pipe 34 through the air feeding pipe 12 and the hose 35, and the serpentine pipe 34 can heat the rust-proof liquid to make it at a temperature of about 30 DEG C, at this time, the rust-proof liquid has good fluidity and will not cause internal substances to volatilize, which is beneficial to the subsequent coating work.

[0059] Then, the air enters into the exhaust box 14 through the air outlet pipe 10 and is discharged through the exhaust groove 33.

[0060] The first transmission roller 3 rotates to drive the driving shaft 17 to rotate, and the driving shaft 17 rotates to drive the linkage shaft 43 to rotate under the cooperation of the first synchronous wheel 18 and the first synchronous belt 19, and the rotating pipe 20 rotates in the opposite direction of the linkage shaft 43 under the transmission of the two gears 44, the transmission shaft 23 rotates under the transmission of the second synchronous belt 22 and the second synchronous wheel 21, the rotating column 37 rotates under the rotation of the transmission shaft 23, the rotating plate 38 rotates under the rotation of the rotating column 37, and the rotating plate 38 cooperates with the circular groove 36, so that the rust-proof liquid in the VCI rust-proof liquid storage tank 7 can be evenly transported to the lower side of the VCI rust-proof liquid storage tank 7 and fall between the VCI rust-proof liquid storage tank 7 and the coating roller 31 when the rotating plate 38 rotates. In this way, the pressure between the coating roller 31 and the VCI rust-proof liquid storage tank 7 is avoided to be too large, so that the rust-proof liquid is not quickly discharged, and the pressure between the coating roller 31 and the VCI rust-proof liquid storage tank 7 can be effectively controlled, and the coating work is more stable and effective.

[0061] The rust-proof liquid is accumulated in the rust-proof liquid storage groove 41, and when the coating roller 31 rotates against the base material, the rust-proof liquid can be discharged through the rust-proof liquid storage groove 41, and the rust-proof liquid is rolled and coated on the base material in a strip shape. Due to the gravity of the rust-proof liquid, the rust-proof liquid is laid outwards, so that the rust-proof liquid is coated on the base material.

[0062] The driving shaft 17 drives the circular plate 15 to rotate, the circular plate 15 drives the connecting rod 27 to move, the connecting rod 27 drives the moving piston 26 to move up and down, when the moving piston 26 moves downward, the hot air in the heating box 8 can be sucked into the piston cylinder 16 through the air inlet pipe 25, when the moving piston 26 moves upward, the hot air in the piston cylinder 16 can be transported into the rotating pipe 20 through the air outlet pipe 24, and finally discharged through the air holes 39; the air holes 39 in the VCI rust-proof liquid storage tank 7 are not easy to discharge air due to the pressure of the rust-proof liquid, and the air holes 39 at other positions can discharge air due to small pressure, so that the rust-proof liquid in the rust-proof liquid storage groove 41 can be more completely coated on the base material, and the rust-proof liquid coated on the base material is more uniform.

[0063] When there is no rust-proof liquid in the rust-proof liquid storage groove 41, the air discharged from the air holes 39 can blow on the rust-proof liquid, so that the dispersion effect of the rust-proof liquid is better, the quality of coating on the base material is ensured, and the quality of subsequent production of rust-proof paper is ensured.

[0064] When the base material coated with the rust-proof liquid is moved to the air outlet box 14, the hot air is discharged through the air outlet groove 33 to blow the base material, so that the base material can be air dried for subsequent pressing work. Gradient drying equipment can also be additionally provided to gradually increase the temperature of the base material for drying, so as to ensure the quality of drying.

[0065] The dried base material passes through the PE film composite pressing mechanism 4, and through unwinding and pressing the PE film, the PE film composite pressing work is realized; similarly, through the PE / PP woven cloth laminating pressing mechanism 5 and the OPP film composite pressing mechanism 6, the PE / PP woven cloth laminating pressing and the OPP film composite pressing are realized, and thus the production of the rust-proof paper is completed.

[0066] After the rust-proof paper is produced, the edge cutting and winding can be performed.

[0067] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art in the technical range disclosed by the present application, according to the technical scheme and the inventive concept of the present application, equivalent replacement or change, should be covered in the protection scope of the present application.
