[0002] Anti-metal rust paint is a special paint, usually composed of resin, pigment, additives, etc. Its main function is to form a protective film on the metal surface to prevent the metal from contacting air, water or chemical substances, thereby extending the service life of metal products.

[0003] In the prior art, a preparation tank is usually used in the process of preparing anti-metal rust paint. After various raw materials of the paint are injected in sequence, they are reacted and mixed, and finally the product paint is obtained. During the process of mixing and processing the raw materials, it is necessary to precisely control the particle size to achieve anti-permeability. The lack of particle adjustment is likely to lead to unqualified protective performance of the paint, and the residues that are not scraped off the inner wall will harden and agglomerate after a long time, and will be mixed into the new batch of paint to cause foreign matter pollution, affecting product consistency.

[0004] When the reaction preparation is carried out after various raw materials of the paint are injected in sequence, the raw materials of each component need to be added in sequence. However, due to different operation methods of different personnel, the differences in the operation process may lead to fluctuations in the paint components, making it difficult to stably control the quality of the paint product, affecting production efficiency and product quality, causing the composition ratio of the paint to deviate from the expected value, and affecting the performance and quality of the paint.

By dynamically crushing, the size of the coating particles is adjusted to ensure uniform dispersion of the coating, avoid roughness on the surface of the coating film layer, improve the quality of the coating product, enhance the protective performance of metal parts, and synchronously realize the stirring function during the treatment process to prevent precipitation and stratification, maintain the uniformity of the coating composition, meet the requirements of the anti - rust coating layer for particle distribution. Second, during the stirring process, the residual coating on the inner wall is automatically scraped off, reducing the risk of hardened caking of the residual material adhering to the inner wall of the preparation tank for a long time and mixing into the new batch, improving the consistency of the coating product, avoiding the growth of microorganisms by residues, and reducing the probability of spoilage and deterioration.

[0017] 2.

[0018] 3. The present invention adopts an intermittent repeated injection for the raw material addition method of the anti-rust paint, allows different functional components (such as epoxy resin, curing agent, anti-rust pigment) to be added in batches, ensures that the component weight of each injection is accurately controlled, avoids local reaction overheating or caking caused by the influence of weight error in one-time mixing, guarantees the sufficient compatibility between the resin base material and the anti-rust filler, dynamically adjusts the addition amount of highly active substances, avoids excessive addition causing coating embrittlement or uneven curing, and ensures the chemical stability of the anti-rust paint; 4. When the present invention sequentially adds different functional components, it can also drive the operation of the heat-uniform fusion mechanism to conduct heat transfer on the raw materials in the preparation tank. Uniform heat transfer can ensure that the resin base material and the anti-rust filler maintain an appropriate viscosity during the mixing process, avoid fluidity differences caused by local temperature differences, thereby improving the dispersion uniformity, and can perform heating treatment while scraping the residual materials adhered to the inner wall of the preparation tank, avoid the paint from solidifying due to temperature influence, ensure the smoothness of the scraping process, and synchronous heat transfer can accelerate the chemical cross-linking reaction between the resin and the curing agent, reduce the micro-region defects of incomplete reaction, and enhance the denseness and salt spray resistance of the coating on the outer wall of the metal part.

[0026] As Figure 1 - Figure 3 , Figure 5 and Figure 7 shown, an anti-metal rust coating production device is used to mix raw materials to produce an anti-metal rust coating. The anti-metal rust coating is composed of the following materials: including a main agent and a curing agent. The main agent includes bisphenol A epoxy resin, bisphenol F epoxy resin, toughening agent, pigment filler, extender pigment, and rust converter. Among them, the mass ratio of bisphenol A epoxy resin and bisphenol F epoxy resin in the main agent is 30%-60%. The anti-metal rust coating production device includes a preparation tank 1, a first stepping motor 2, a mixing and confluence mechanism 6, an anti-accumulation mechanism 7, a quantitative feeding mechanism 8, and a heat-uniforming and fusing mechanism 9. The first stepping motor 2 is fixedly connected to the top of the preparation tank 1; The mixing and confluence mechanism 6 plays a role in mixing and preventing adhesion of the coating in the preparation tank 1. The anti-accumulation mechanism 7 realizes the accelerated output effect of the coating at the bottom of the preparation tank 1. The quantitative feeding mechanism 8 and the heat-uniforming and fusing mechanism 9 can dynamically add coating components and achieve the effect of heat-uniforming and preventing curing; Specifically: The mixing and confluence mechanism 6 dynamically breaks and adjusts the particle size of the coating to ensure uniform dispersion of the coating, avoid roughness on the surface of the coating film, improve the quality of the coating product, enhance the subsequent protection performance for metal parts, and synchronously realize the stirring function during the treatment process to prevent precipitation and stratification, maintain the uniformity of the coating composition, meet the high requirements of the anti-rust coating layer for particle distribution. Second, during the stirring process, it automatically scrapes the residual coating on the inner wall, reduces the risk of hardened lumps of the residual material adhering to the inner wall of the preparation tank for a long time from mixing into the new batch, improves the consistency of the coating product, avoids the growth of microorganisms by the residues, and reduces the probability of spoilage and deterioration.

[0027] As Figures 5 - 9As shown in the figure, the hybrid current collecting mechanism 6 includes a central shaft body 601 fixedly connected to the driving end of the first stepping motor 2. The outer wall of the central shaft body 601 is fixedly connected with a supporting plate 602. The top of the supporting plate 602 is fixedly connected with a transmission member 603. The inner walls of the four corners of the transmission member 603 are all slidably connected with adjusting rods 604. A plurality of guiding members 605 are fixedly connected to the top of the supporting plate 602 in a circumferential manner. The outer walls of the adjusting rods 604 are respectively slidably connected to the inner walls of the guiding members 605. The far ends of the adjusting rods 604 are all fixedly connected with crushing rollers 606. A threaded groove 607 is opened in the middle of the outer wall of the central shaft body 601. A threaded sleeve rod 608 is threadedly connected to the outer wall of the threaded groove 607. A grid expansion plate 609 is fixedly connected to the middle of each pair of crushing rollers 606. A strip-shaped hole 610 is opened in the middle of the outer walls of the two grid expansion plates 609. The outer walls of the two ends of the threaded sleeve rod 608 are respectively slidably connected to the inner walls of the two strip-shaped holes 610. The middle parts of the outer walls of the two grid expansion plates 609 are both slidably connected with trigger plates 611. The two trigger plates 611 are respectively fixedly connected to the two ends of the threaded sleeve rod 608. Oblique grooves 612 are opened in the middle parts of the two sides of the two trigger plates 611. A pair of guiding rods 613 are fixedly connected to the middle of the outer walls of the two grid expansion plates 609. A pair of current collecting scraping plates 614 are slidably connected to the outer walls of the two guiding rods 613. The two current collecting scraping plates 614 are respectively slidably connected to the inner walls of the two oblique grooves 612 through the pins fixedly connected to their inner sides; Specifically, by driving the central shaft body 601 to rotate alternately 360 degrees forward and backward by the first stepping motor 2 to drive the supporting plate 602 to rotate inside the preparation tank 1, the transmission member 603 can be synchronously rotated, and with the cooperation of each guiding member 605, each adjusting rod 604 can be driven to slide back and forth on the top of the supporting plate 602, so as to realize the distance between each crushing roller 606 and the inner wall of the preparation tank 1. During the rotation of the crushing roller 606 along with the central shaft body 601, the adjustment of the particle size of the broken particles of the coating raw material is realized, ensuring the uniform dispersion of the coating, avoiding the roughness of the surface of the coating film layer, and improving the quality of the coating product; At the same time, with the rotation of the central shaft body 601, the threaded sleeve rod 608 on the outer wall of the central threaded groove 607 can realize vertical movement, and the threaded sleeve rod 608 drives the trigger plates 611 fixed at both ends to slide along the inner wall of the strip hole 610 opened in the middle of the grille telescopic plate 609. The telescopicity of the grille telescopic plate 609 can correspond to the tolerance of the extension and retraction process of the crushing rollers 606 on both sides. The grille telescopic plate 609 can refer to the telescopic fence structure in the prior art, which will not be described here. With the vertical movement of the trigger plate 611 and the cooperation of the inclined grooves 612 symmetrically opened in the shape of an eight on both sides, the converging scrapers 606 on both sides are 14 moves closer to or away from the outer wall of the guide rod 613. The material of the guide rod 613 is polyurethane high-resilient material, which corresponds to the deformation amount generated during the adjustment of the grid telescopic plate 609. During the movement of the converging scrapers 614 on both sides, the paint remaining on the inner wall of the preparation tank 1 can be scraped and collected to one place, and flowed and transported along the wedge-shaped surface at the bottom of the converging scraper 614 under the action of gravity. The uniform flow of the paint can avoid local overload, reduce the risk of equipment blockage or abnormal pressure, ensure the stability and uniformity of the internal environment of the preparation tank 1, reduce the adhesion of dry and solid paint on the inner wall, avoid wear of the production and processing mechanism, and extend the service life of the equipment.

[0028] like Figures 6 - 7 and Figure 9 As shown, the anti-accumulation mechanism includes an annular frame 701, the outer wall of the annular frame 701 is fixedly connected to the lower inner wall of the preparation tank 1, and the two sides of the bottom end of the central axis 601 are fixedly connected to the limiting ball rods 702, and the outer walls of the limiting ball rods 702 on both sides are slidably connected to the inner wall of the annular frame 701, and the bottoms of the limiting ball rods 702 on both sides are fixedly connected to the push plates 703, and the bottoms of the push plates 703 on both sides are rotatably connected to the bottom of the inner wall of the preparation tank 1; Specifically, during the rotation of the central axis 601, the limiting ball rods 702 on both sides can be driven to rotate synchronously. The limiting ball rods 702 and the center line of the annular frame 701 are located on the same straight line, so that the limiting ball rods 702 on both sides slide along the inner wall of the annular frame 701, forming a rigid trajectory constraint, which can suppress the radial runout of the central axis 601, and is particularly suitable for scenarios with high rotation speed or high load of coating raw materials, to avoid damage to production equipment caused by eccentric vibration.

[0029] like Figures 1 - 2 and Figure 4As shown in the figure, the metering and feeding mechanism 8 includes a second stepping motor 801 fixedly connected to the top of the preparation tank 1. The driving end of the second stepping motor 801 is fixedly connected with a shaft rod 802. The shaft rod 802 is rotatably connected to the top of the preparation tank 1. A connecting piece 804 is fixedly connected to the outer wall of the shaft rod 802. A feeding cylinder 808 is rotatably connected to the top of the preparation tank 1. A main bevel gear 803 is fixedly connected to the outer wall of the shaft rod 802. A sub-bevel gear 805 is rotatably connected to the top of the connecting piece 804. The sub-bevel gear 805 is meshed with the main bevel gear 803. A threaded rod 806 is fixedly connected to the top of the sub-bevel gear 805. A movable block 807 is threadedly connected to the outer wall of the threaded rod 806. The feeding cylinder 808 is rotatably connected to the movable block 807; Specifically, the threaded rod 806 follows the rotation trajectory of the shaft rod 802 synchronously and obliquely through the cooperation of the connecting piece 804. By driving the shaft rod 802 to rotate by the second stepping motor 801, the threaded rod 806 can be driven to achieve oblique adjustment and synchronous rotation under the cooperation of the connecting piece 804 and the meshed main bevel gear 803 and sub-bevel gear 805. With the cooperation of the threadedly connected movable block 807, the feeding cylinder 808 can rotate towards the side of the feeding pipe 3 by itself, and intermittently pour the weighed and proportioned raw material components inside it into the preparation tank 1.

[0030] As Figures 1 - 4 and Figure 10 As shown in the figure, the heat homogenization and fusion mechanism 9 includes an eccentric wheel 901. The eccentric wheel 901 is fixedly connected to the end of the shaft rod 802 away from the second stepping motor 801. An eccentric rod 902 is rotatably connected to the inner wall of the edge of the eccentric wheel 901. A groove 905 is opened in the middle of the eccentric rod 902. A guide block 904 is fixedly connected to the outer wall of the preparation tank 1 near the eccentric rod 902. The outer wall of the guide block 904 is slidably connected to the groove 905. A heating ring 903 is fixedly connected to the bottom end of the eccentric rod 902. The inner wall of the heating ring 903 is slidably connected to the outer wall of the preparation tank 1. A control panel 10 is fixedly connected to the rear side of the outer wall of the preparation tank 1. The control panel 10 is electrically connected to the first stepping motor 2, the threaded sleeve rod 608, the second stepping motor 801, the heating ring 903 and the valve 12; Specifically, the movement trajectory of the eccentric rod 902 coincides with the center line of the guide block 904. An electric heating wire (not shown in the figure, which is prior art and will not be elaborated here) is provided inside the heating ring 903. As the shaft rod 802 operates and rotates, it can drive the eccentric wheel 901 to rotate accordingly, and drive the eccentric rod 902 to move back and forth in the vertical direction along the rotation trajectory of the eccentric wheel 901. The settings of the guide block 904 and the groove 905 can limit the movement path of the eccentric rod 902, ensuring that it can drive the heating ring 903 to move stably on the outer wall of the preparation tank 1, heat the raw material components in the tank, and perform heating while scraping the residual materials adhered to the inner wall of the preparation tank 1, avoiding the solidification of the coating due to temperature influence and ensuring the smoothness of the scraping process.

[0031] A method for preparing an anti-metal rust coating, which is applied to an anti-metal rust coating production device, includes the following steps: Step 1: Mix the epoxy resin mixture and silica sol ( content 20%) with a content of 20% and stir at 160 rpm; Step 2: Add a phytic acid solution with a concentration of 1.5% and water for dilution, and control the continuous stirring time within 2 hours; Step 3: Heat up to 40–50 °C, add the additives agar and polytetrafluoroethylene, stir evenly and then cool naturally; In Step 1, the processing speed of the first stepping motor 2 is controlled at 160–200 r / min to ensure uniform dispersion of the components. In Step 3, the natural cooling temperature is controlled at 40-50 °C to control the quality of the subsequent film formation of the coating.

[0032] Working principle: First, rotate each latch bolt 5 to open the sealing cover 4 from the top of the injection pipe 3. After weighing the corresponding raw materials of different functional components to be processed, pour them into the interior of the injection cylinder 808. By driving the shaft rod 802 to rotate with the second stepping motor 801, the threaded rod 806 can be driven to achieve tilt adjustment and synchronous rotation under the cooperation of the connecting member 804 and the meshing main bevel gear 803 and sub-bevel gear 805. With the cooperation of the movably block 807 connected by threads, the injection cylinder 808 itself can be rotated toward the side of the injection pipe 3, and the weighed and proportioned raw material components inside it can be intermittently and repeatedly poured into the interior of the preparation tank 1. As the shaft rod 802 operates and rotates, the eccentric wheel 901 can be driven to rotate accordingly, and the eccentric rod 902 can be driven to move back and forth in the vertical direction along the rotation trajectory of the eccentric wheel 901. The setting of the guide block 904 and the groove 905 can limit the movement path of the eccentric rod 902, ensuring that it can drive the heating ring 903 to move stably on the outer wall of the preparation tank 1 to heat the raw material components in the tank, ensuring the stability of the reaction preparation process. At the same time, during the process of the confluence scraper 614 treating the residual materials adhered to the inner wall of the preparation tank 1, the tank wall of the preparation tank 1 can be maintained at a certain temperature, preventing the residual materials from solidifying and adhering due to temperature influence, reducing the risk of the hardened and caked residual materials adhered to the inner wall of the preparation tank 1 for a long time from mixing into the new batch, improving the consistency of the coating product, avoiding the growth of microorganisms by the residues, and reducing the probability of spoilage; The first stepping motor 2 drives the central shaft body 601 to drive the supporting plate 602 to rotate inside the preparation tank 1 in a way of rotating back and forth 360 degrees in both positive and negative directions, so that the transmission member 603 rotates, and with the cooperation of each guiding member 605, each adjusting rod 604 is driven to slide back and forth on the top of the supporting plate 602, thereby realizing the distance between each crushing roller 606 and the inner wall of the preparation tank 1. During the rotation of the crushing roller 606 along with the central shaft body 601, the adjustment of the particle size of the broken particles of the coating raw materials is realized, ensuring the uniform dispersion of the coating, avoiding the roughness of the surface of the coating film layer, and improving the quality of the coating product; With the rotation of the central shaft body 601, the threaded sleeve rod 608 on the outer wall of the middle threaded groove 607 thereof can achieve vertical movement. The threaded sleeve rod 608 drives the trigger plates 611 fixed at both ends thereof to slide along the inner wall of the strip-shaped hole 610 opened in the middle of the grille telescopic plate 609. The telescopic property of the grille telescopic plate 609 can correspondingly match the receptivity during the extension and retraction process of the two crushing rollers 606 on both sides. The grille telescopic plate 609 can refer to the telescopic fence structure in the prior art and will not be elaborated here. With the vertical movement of the trigger plate 611 and the cooperation of the inclined grooves 612 symmetrically opened in an eight-shaped manner on both sides, the two confluence scraping plates 614 move closer to or away from each other along the outer wall of the guide rod 613, scraping and collecting the residual paint on the inner wall of the preparation tank 1 to one place, and flowing and transporting it along the wedge-shaped surface at the bottom of the confluence scraping plate 614 under the action of gravity. The paint can flow evenly to the bottom of the preparation tank 1 to avoid local overload, reducing the risk of equipment blockage or abnormal pressure. The material of the guide rod 613 is selected as a polyurethane high-elasticity material to correspondingly match the deformation amount generated during the adjustment of the grille telescopic plate 609; Finally, after the metal anti-rust paint is prepared, when the valve 12 is opened, the paint product can flow out along the inner wall of the output pipe 11.
