Description

Technical Field

[0001] The invention relates to the technical field of coating processing, in particular to a preparation device and a preparation method of a wear-resistant epoxy ceramic coating. Background Art

[0002] Epoxy ceramic coating is a solvent-free two-component epoxy coating made with epoxy resin as the base material, quartz powder and additives. This type of coating has excellent mechanical strength, toughness and chemical resistance, and is widely used in the anti-corrosion treatment of surfaces such as the inner walls of pipelines, steel storage tanks, and concrete pools.

[0003] When preparing epoxy ceramic coatings, epoxy resin and a variety of additives need to be added to the barrel together. The ratio between the additives and the epoxy resin needs to be precisely controlled. Usually, the epoxy resin and various additives are evenly mixed by rotating the stirring plate. If the stirring plate rotates too fast or the viscosity of the material itself is low, part of the material will splash onto the inner wall of the barrel during the stirring process. Since the coating itself has a certain viscosity, it takes a certain amount of time for the material to slide off the inner wall. Even if the material eventually slides off, it mostly falls to the surrounding areas of the barrel. The material circulation in these areas is poor, which can easily lead to uneven material composition and inconsistent material ratios in local areas, affecting the consistency and performance of the overall coating.

[0004] Therefore, it is necessary to design a preparation equipment that ensures the uniformity of coating mixing. Summary of the Invention

DETAILED DESCRIPTION

[0039] See also Figures 1-12 In an embodiment of the present invention, a preparation device for wear-resistant epoxy ceramic coating includes a stirring barrel 1, wherein a rotating shaft 2 is movably provided in the stirring barrel 1, a positioning ring 3 is movably sleeved on the outer top of the rotating shaft 2, and the positioning ring 3 is fixedly connected to the inner wall of the stirring barrel 1, and a plurality of stirring rods 4 are fixedly provided in an annular array on the outer side of the rotating shaft 2, and the stirring barrel 1 is rotatably provided with a cylinder 5 above the rotating shaft 2, and a fixed frame 6 is fixedly provided on both sides of the cylinder 5 axially symmetrically, and a moving cylinder 7 is movably provided in the fixed frame 6, and a scraping assembly 8 is provided on one side of the moving cylinder 7, and a driving assembly 9 capable of driving the scraping assembly 8 to move is provided in the fixed frame 6; epoxy resin and various additives are added into the stirring barrel 1, and the additives may include bentonite, xylene, non-silicone leveling agent, silane coupling agent and the like, and the epoxy resin is mixed with the epoxy resin. Grease and additives are added to the mixing barrel 1 according to the set ratio, and the motor of the rotating shaft 2 is started. The rotation of the rotating shaft 2 will drive the stirring rod 4 to rotate so that the epoxy resin and various additives are evenly mixed. The positioning ring 3 provides support for the rotating shaft 2 and the rotating cylinder 5. The rotation of the cylinder 5 will drive the fixed frame 6 and the movable cylinder 7 to rotate synchronously. The rotation of the movable cylinder 7 drives the scraper assembly 8 to rotate along the inside of the mixing barrel 1, thereby scraping the paint splashed on the inner wall into the scraper assembly 8. Then, the drive assembly 9 is used to drive the scraper assembly 8 to move along the fixed frame 6 to the middle of the mixing barrel 1, and pour the paint in the scraper assembly 8 into the middle position of the paint below, because the center of the mixing barrel 1 is stirred more strongly than the edge position, because the rotation of the stirring plate can produce a greater fluid dynamic effect here, which can effectively mix the material scraped from the inner wall of the mixing barrel 1.

[0040] See Figure 3-Figure 5As shown, in this embodiment, preferably, the scraper assembly 8 includes a moving frame 81, and the contact position between the moving frame 81 and the inner wall of the mixing barrel 1 is designed to be arc-shaped. A plurality of inclined plates 82 are provided on the moving frame 81, and a rotating rod 83 is fixedly connected to one side of the moving frame 81. The outer side of the moving cylinder 7 is fixedly connected to the moving plate 10, and one end of the rotating rod 83 movably passes through the moving plate 10; the rotation of the cylinder 5 drives the moving cylinder 7 to rotate, and the rotation of the moving cylinder 7 drives the moving plate 10 and the rotating rod 83 to rotate synchronously, and the rotation of the rotating rod 83 drives the moving frame 81 to rotate, and the contact position between the moving frame 81 and the inner wall of the mixing barrel 1 is designed to be arc-shaped, so that the moving frame 81 can abut against the inner wall of the mixing barrel 1 more tightly, so that the paint splashed on the inner wall of the mixing barrel 1 can be easily scraped off, and the scraped paint flows into the moving frame 81 along the inclined plate 82.

[0041] See Figure 3-Figure 5 As shown, in this embodiment, preferably, the driving assembly 9 includes a screw rod 91, which is rotatably connected to the fixed frame 6, and the moving cylinder 7 is movably sleeved on the outside of the screw rod 91. A sliding groove 92 is provided at the bottom of the fixed frame 6, and the moving plate 10 is slidably connected to the sliding groove 92; after the scraped paint flows into the moving frame 81 along the inclined plate 82, the screw rod 91 is rotated. The rotation of the screw rod 91 will drive the moving cylinder 7 to a position close to the middle of the mixing barrel 1, and the moving plate 10 moves along the sliding groove 92. The movement of the moving plate 10 along the sliding groove 92 is to prevent the moving cylinder 7 and the moving plate 10 from rotating with the rotation of the screw rod 91, so as to avoid the paint in the moving frame 81 from pouring into the paint below if it is not moved to the middle position of the mixing barrel 1.

[0042] See Figure 3 and Figure 6As shown, in this embodiment, preferably, the bottom of the fixed frame 6 is fixedly provided with an arc plate 11, and a limiting groove 111 is provided on the arc plate 11, and the limiting groove 111 consists of a straight groove and a curved groove. A limiting rod 12 is slidably provided in the limiting groove 111, and the limiting rod 12 is fixedly connected to the rotating rod 83 away from the side of the moving frame 81, and the moving cylinder 7 is slidably connected to the arc plate 11; during the movement of the rotating rod 83 and the moving frame 81 toward the center position of the mixing barrel 1, the limiting rod 12 first moves along the straight groove section of the limiting groove 111 provided on the arc plate 11. During this process, the rotating rod 83 and the moving frame 81 will not rotate. When the limiting rod 12 moves to the curved groove section, the rotating rod 83 will rotate, and the rotation of the rotating rod 83 will drive the moving frame 81 to rotate so that the paint in the moving frame 81 is poured into the paint below, thereby realizing the transfer of the paint and ensuring the uniformity of the paint mixing.

[0043] See Figure 7 As shown, in this embodiment, preferably, a circular groove 101 is opened in the movable plate 10, and a circular ring 13 is movably provided in the circular groove 101. A fixed ring 14 is fixedly sleeved on the outer side of the rotating rod 83, and the fixed ring 14 is rotatably connected to the circular groove 101. A plurality of springs 15 are fixedly connected between the fixed ring 14 and the circular ring 13; the rotation of the screw rod 91 will drive the movable cylinder 7 and the movable plate 10 to move synchronously together, and the movement of the movable plate 10 will drive the rotating rod 83 to move synchronously with the help of the positional relationship between the circular groove 101, the circular ring 13 and the fixed ring 14. When the rotating rod 83 rotates, it will drive the fixed ring 14 to rotate synchronously. Since a spring 15 is fixedly provided between the fixed ring 14 and the circular ring 13, the rotation of the fixed ring 14 will drive the spring 15 and the circular ring 13 to rotate synchronously, thereby realizing the pouring of paint.

[0044] See Figure 8-Figure 9As shown, in this embodiment, preferably, the movable plate 10 is fixedly provided with a fixed cylinder 16 on one side of the movable frame 81, and the rotating rod 83 movably passes through the fixed cylinder 16, and a plurality of balls 17 are fixedly provided in the fixed cylinder 16, and a plurality of circular holes 831 are opened on the inner side of the rotating rod 83, and the circular holes 831 movably abut against the balls 17; when the limiting rod 12 moves along the straight groove section of the limiting groove 111, the rotating rod 83 and the fixed cylinder 16 remain relatively stationary, and the two move synchronously, and the balls 17 are located in the circular holes 831. When the limiting rod 12 contacts the curved groove section of the limiting groove 111, it will drive the rotating rod 83 to rotate, and the rotating rod 83 will rotate relative to the fixed cylinder 16. The rotation of the rotating rod 83 will drive the circular holes 831 to rotate, and in this process, the balls 17 will alternately abut against the circular holes 831 and then The cam 83 is then released from the engagement, which causes the rotating rod 83 to vibrate, and the vibrating of the rotating rod 83 causes the fixing ring 14 to vibrate. Since the fixing ring 14 and the circular ring 13 are fixedly connected by the spring 15, and the diameter of the rotating rod 83 is smaller than the diameter of the opening of the movable plate 10, the rotating rod 83 can vibrate while rotating relative to the movable plate 10. The vibrating of the rotating rod 83 causes the movable frame 81 to vibrate during the flipping process, which can speed up the outflow speed of the paint in the movable frame 81. When the movable frame 81 is about to return to abut against the inner wall of the mixing barrel 1, the screw rod 91 can be rotated in the opposite direction. The rotating rod 83 will rotate first to make the movable frame 81 flip back to its initial state, and the circular hole 831 and the sphere 17 will abut against each other again. This can also ensure the stability of the movable frame 81 and the rotating rod 83 itself when the movable frame 81 rotates along the inner wall of the mixing barrel 1.

[0045] See Figure 10 and Figure 11 As shown, in this embodiment, preferably, the cylinder 5 is provided with a notch 51 at the position of the fixed frame 6, and a vertical rod 18 is movably provided in the cylinder 5, one end of the vertical rod 18 movably passes through the top of the mixing barrel 1, and a first bevel gear 19 is fixedly sleeved on the outside of the vertical rod 18, and the end of the screw rod 91 away from the fixed frame 6 is located in the notch 51 and a second bevel gear 20 is fixedly provided at the end, and the second bevel gear 20 is meshed with the first bevel gear 19 for transmission; when the vertical rod 18 rotates relative to the cylinder 5, the first bevel gear 19 will be driven to rotate, thereby driving the second bevel gear 20 and the screw rod 91 to rotate, and the rotation of the screw rod 91 will drive the movable cylinder 7, the movable plate 10, the rotating rod 83 and the movable frame 81 to move toward the center position of the mixing barrel 1, so as to facilitate the transportation of the paint to the center position of the mixing barrel 1 and ensure that the paint is evenly mixed. The notch 51 is to facilitate the meshing transmission of the first bevel gear 19 and the second bevel gear 20.

[0046] See Figure 10 and Figure 11As shown, in this embodiment, preferably, a rotating plate 21 and a baffle 22 are fixedly provided on the outer side of the vertical rod 18 and the inner side of the cylinder 5, respectively, and the rotating plate 21 is movably abutted against the baffle 22; the clockwise rotation of the vertical rod 18 will drive the rotating plate 21 and the baffle 22 to rotate synchronously, and the rotation of the baffle 22 will drive the cylinder 5 to rotate so that the movable frame 81 can rotate along the inner wall of the mixing barrel 1 to scrape the splashed paint into the movable frame 81, and then the vertical rod 18 is rotated in the opposite direction. When rotating in this direction, the rotating plate 21 does not abut against the baffle 22, and the cylinder 5 does not rotate. The rotation of the vertical rod 18 will drive the first bevel gear 19 to rotate relative to the second bevel gear 20, thereby driving the second bevel gear 20 and the screw 91 to rotate so that the movable frame 81 moves toward the center position of the mixing barrel 1, so as to facilitate pouring the paint into the center position of the mixing barrel 1.

[0047] See Figure 12As shown, in this embodiment, preferably, a first gear 23 is fixedly provided on the top of the vertical rod 18, a round rod 24 is rotatably provided on the top of the mixing barrel 1 on one side of the vertical rod 18, a turntable 25 is fixedly provided on the top of the round rod 24, a driving gear 26 is fixedly provided on the inside of the turntable, the driving gear 26 is meshed with the first gear 23 for transmission, an incomplete gear 27 is fixedly provided on the outside of the round rod 24, and the incomplete gear 27 is meshed with the first gear 23 for transmission; in the initial state, the middle position of the driving gear 26 is meshed with the first gear 23, and the incomplete gear The wheel 27 is provided with one end of the gear away from the first gear 23, and the round rod 24 is rotated clockwise. The rotation of the round rod 24 drives the turntable 25, the driving gear 26 and the incomplete gear 27 to rotate clockwise. The complete driving gear 26 can drive the first gear 23 to rotate one circle. Since only half of the gear of the driving gear 26 is engaged with the first gear 23 at this time, the driving gear 26 can only drive the first gear 23 to rotate half a circle. The clockwise rotation of the first gear 23 half a circle will drive the vertical rod 18 and the rotating plate 21 to rotate half a circle, and will drive the baffle 22 and the cylinder 5 to rotate half a circle clockwise, so that both sides The moving frame 81 also rotates half a circle, just rotating one circle along the inner wall of the mixing barrel 1, scraping the splashed paint into the moving frame 81. During this process, the vertical rod 18 and the cylinder 5 keep rotating synchronously, and the first bevel gear 19 and the second bevel gear 20 do not rotate relative to each other. Then the driving gear 26 is disengaged from the first gear 23, and the incomplete gear 27 is engaged with the first gear 23, thereby driving the first gear 23 and the vertical rod 18 to rotate half a circle counterclockwise. During this process, the rotating plate 21 does not abut against the baffle 22, so the cylinder 5 remains stationary, and the rotation of the first bevel gear 19 drives the second bevel gear 20 and the screw rod 9 1 rotates, causing the movable frame 81 to move toward the center of the mixing barrel 1. Subsequently, the incomplete gear 27 is released from contact with the first gear 23. Then, the complete driving gear 26 is meshed with the first gear 23 again, thereby driving the vertical rod 18 to rotate one circle clockwise. In the first half circle, the rotating plate 21 will not abut against the baffle 22. During this process, the second bevel gear 20 and the screw rod 91 will be driven to rotate in the opposite direction, causing the movable frame 81 to abut against the inner wall of the mixing barrel 1 again. The second half circle will drive the baffle 22 and the cylinder 5 to rotate half a circle again, causing the movable frame 81 to scrape off the paint on the inner wall of the mixing barrel 1. The above steps are repeated.

[0048] In this embodiment, preferably, the following steps are included: S1, adding various raw materials into the mixing barrel 1, starting the motor of the rotating shaft 2, and the rotating shaft 2 drives the stirring rod 4 to mix the raw materials evenly;

[0049] S2, start the motor of the round rod 24, the rotation of the round rod 24 drives the turntable 25 to rotate, thereby driving the driving gear 26 and the incomplete gear 27 to alternately engage with the first gear 23, causing the first gear 23 to reciprocate forward and reverse rotation;

[0050] S3, the round rod 24 rotates one circle clockwise, which drives the driving gear 26 to drive the first gear 23 to rotate one circle clockwise. Then the incomplete gear 27 drives the first gear 23 to rotate half a circle counterclockwise. The first gear 23 is driven to rotate in this manner.

[0051] S4, the first gear 23 rotates one circle clockwise, which drives the vertical rod 18 and the rotating plate 21 to rotate, thereby driving the baffle 22 and the cylinder 5 to rotate synchronously, so that the fixed frame 6, the rotating rod 83 and the movable frame 81 rotate. The second bevel gear 20 and the first bevel gear 19 do not rotate relative to each other during this process;

[0052] S5, the first gear 23 rotates half a circle counterclockwise to drive the vertical rod 18 and the first bevel gear 19 to rotate. During this process, the baffle 22 and the rotating plate 21 do not abut, and the cylinder 5 remains stationary. The rotation of the first bevel gear 19 will drive the second bevel gear 20 and the screw rod 91 to rotate, and the rotation of the screw rod 91 will drive the movable cylinder 7, the movable plate 10, the rotating rod 83 and the movable frame 81 to move toward the center of the mixing barrel 1; various raw materials are added to the mixing barrel 1, and the motor of the rotating shaft 2 is started. The rotating shaft 2 drives the stirring rod 4 to mix the raw materials evenly, and the motor of the round rod 24 is started. The rotation of the round rod 24 drives the turntable 25 to rotate, thereby driving the driving gear 26 and the incomplete gear 27 to alternately engage with the first gear 23 for transmission, so that the first gear 23 rotates back and forth in both directions. The round rod 24 rotates one circle clockwise to drive the driving gear 26 to drive the first gear 23 rotates one circle clockwise, and then the incomplete gear 27 drives the first gear 23 to rotate half a circle counterclockwise, maintaining this rule to drive the first gear 23 to rotate. The clockwise rotation of the first gear 23 will drive the vertical rod 18 and the rotating plate 21 to rotate, thereby driving the baffle 22 and the cylinder 5 to rotate synchronously, so that the fixed frame 6, the rotating rod 83 and the movable frame 81 rotate, and the second bevel gear 20 and the first bevel gear 19 will not rotate relative to each other during this process. The counterclockwise rotation of the first gear 23 half a circle will drive the vertical rod 18 and the first bevel gear 19 to rotate. During this process, the baffle 22 and the rotating plate 21 do not abut, and the cylinder 5 remains stationary. The rotation of the first bevel gear 19 will drive the second bevel gear 20 and the screw rod 91 to rotate, and the rotation of the screw rod 91 will drive the movable cylinder 7, the movable plate 10, the rotating rod 83 and the movable frame 81 to move toward the center of the mixing barrel 1.

[0053] The working principle of the present invention is: epoxy resin and additives are added to the mixing barrel 1 according to a set ratio, the motor of the rotating shaft 2 is started, the rotation of the rotating shaft 2 will drive the stirring rod 4 to rotate so that the epoxy resin and various additives are evenly mixed, the positioning ring 3 provides support for the rotating shaft 2, and in the initial state, the middle position of the driving gear 26 is engaged with the first gear 23, and the incomplete gear 27 is provided with one end of the gear away from the first gear 23, and the round rod 24 is rotated clockwise. The rotation of the round rod 24 drives the turntable 25, the driving gear 26 and the incomplete gear 27 to rotate clockwise. The complete driving gear 26 can drive the first gear 23 to rotate one circle. Since only half of the gear of the driving gear 26 is engaged with the first gear 23 at this time, the driving gear 26 At first, it can only drive the first gear 23 to rotate half a circle. The clockwise rotation of the first gear 23 will drive the vertical rod 18 and the rotating plate 21 to rotate half a circle, and will drive the baffle 22 and the cylinder 5 to rotate half a circle clockwise, so that the moving frames 81 on both sides also rotate half a circle, just rotating one circle along the inner wall of the mixing barrel 1, scraping the splashed paint into the moving frame 81. During this process, the vertical rod 18 and the cylinder 5 keep rotating synchronously, and the first bevel gear 19 and the second bevel gear 20 will not rotate relative to each other. Then the driving gear 26 is disengaged from the first gear 23, and the incomplete gear 27 is engaged with the first gear 23, thereby driving the first gear 23 and the vertical rod 18 to rotate half a circle counterclockwise. During this process, the rotating plate 21 does not abut against the baffle 22, so the cylinder 5 remains stationary, and the first bevel gear 19 and the second bevel gear 20 do not rotate relative to each other. The rotation of the gear 19 will drive the second bevel gear 20 and the screw rod 91 to rotate, and the rotation of the screw rod 91 will drive the movable cylinder 7 and the movable plate 10 to move synchronously. The movement of the movable plate 10 will drive the rotating rod 83 to move synchronously with the help of the positional relationship between the circular groove 101, the circular ring 13 and the fixed ring 14. The rotation of the screw rod 91 will drive the movable cylinder 7 and the movable plate 10 to move synchronously. The movement of the movable plate 10 will drive the rotating rod 83 to move synchronously with the help of the positional relationship between the circular groove 101, the circular ring 13 and the fixed ring 14. When the limiting rod 12 moves along the straight groove section of the limiting groove 111, the rotating rod 83 and the fixed cylinder 16 remain relatively stationary, and the two move synchronously. The sphere 17 is located in the circular hole 831. When the limiting rod 12 and the limiting groove 111 are in contact with each other, the rotating rod 83 and the fixed cylinder 16 remain relatively stationary. The two move synchronously. After the curved groove section of 11 contacts, it will drive the rotating rod 83 to rotate, and the rotating rod 83 will rotate relative to the fixed cylinder 16. The rotation of the rotating rod 83 will drive the circular hole 831 to rotate. During this process, the ball 17 will alternately abut against the circular hole 831 and then release the abutment, which will drive the rotating rod 83 to shake. The shaking of the rotating rod 83 will drive the fixed ring 14 to shake. Since the fixed ring 14 and the circular ring 13 are fixedly connected by the spring 15, and the diameter of the rotating rod 83 is smaller than the opening diameter of the movable plate 10, the rotating rod 83 will shake while rotating relative to the movable plate 10. The shaking of the rotating rod 83 will drive the movable frame 81 to shake during the flipping process, which can speed up the outflow speed of the paint in the movable frame 81.Then the incomplete gear 27 is released from contact with the first gear 23, and the complete drive gear 26 is meshed with the first gear 23 again, driving the vertical rod 18 to rotate one circle clockwise. The first half circle of the rotating plate 21 will not abut against the baffle 22. During this process, the second bevel gear 20 and the screw rod 91 will rotate in the opposite direction, causing the moving frame 81 to abut against the inner wall of the mixing barrel 1 again. The second half circle will drive the baffle 22 and the cylinder 5 to rotate another half circle, causing the moving frame 81 to scrape the paint off the inner wall of the mixing barrel 1. The above steps are repeated.
