Description

Technical Field

[0001] This invention relates to the field of sheet coating production technology, and more specifically, to a coating production system, a coating production process, and a graphene-coated aluminum sheet. Background Technology

[0002] In the coating process of strip materials, coating rollers or doctor blades are typically used to coat the surface of the strip, thereby forming a coating layer of appropriate thickness. Theoretically, the doctor blade of the coating device adheres closely to the surface of the strip, ensuring consistent coating pressure across the width of the strip. However, in reality, the strip often exhibits a sag in the middle, especially when the strip width exceeds 2 meters. This sag has a greater impact, meaning the strip is relatively taut near the edges and relatively loose in the middle. During coating, the doctor blade and strip exert higher pressure near the edges and lower pressure in the middle, sometimes even creating minute gaps in the middle. The coating thickness is thicker in the lower-pressure middle section and thinner at the edges, affecting the coating quality of the strip surface.

[0003] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a graphene-coated aluminum plate, coating production process and system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a coating production system, including a scraper mechanism, the scraper mechanism including a scraper and an adjusting frame, the scraper having an upward scraping blade portion, the scraping blade portion being used to abut against the belt to be coated; the scraper is disposed at the mounting position of the adjusting frame, the scraper is divided into a middle scraper section and two side scraper edge sections along its length direction, the two side scraper edge sections are slidably mounted at the mounting position along the length direction of the scraper, and the middle scraper section is capable of generating a horizontal elastic bending bulge.

[0006] The present invention is further configured such that the installation position is divided into a middle section and two side sections along the length direction, the side sections of the installation position are provided with adjustment grooves, the scraper side sections are fixedly connected with sliders, the sliders are embedded in the adjustment grooves and are slidably connected to the adjustment grooves.

[0007] The invention is further configured such that a deformation notch is provided in the middle section of the installation position facing the input side of the belt, and the deformation notch allows the scraper to bend and bulge elastically.

[0008] The present invention is further configured such that the scraper is made of a polymer material, and an elastic padding layer is laminated on the side of the scraper facing away from the raised direction, wherein the elastic padding layer is a shape memory alloy.

[0009] The invention is further configured such that rotating shafts are fixedly connected to both sides of the adjusting frame, the rotating shafts are rotatably mounted on the frame, and the axis of the rotating shafts coincides with the scraper blade in its unbent state.

[0010] The present invention is further configured such that the scraper mechanism includes two sets of adjustment components, and the scraper edge section and the adjustment frame are adjusted by the adjustment components.

[0011] The present invention is further configured such that the adjusting assembly includes an adjusting block one, an adjusting block two, an adjusting screw, and an adjusting nut. The adjusting block one is fixedly installed on the outside of the adjusting frame. The adjusting frame has an adjusting groove, which is arranged along the sliding direction of the slider. The adjusting block two is slidably installed thereon. One side of the adjusting block two is fixedly connected to the slider, and the other side extends to the outside of the adjusting frame. One side of the adjusting screw is fixedly connected to the adjusting block one, and the other end of the adjusting screw extends toward the end of the scraper, passes through the adjusting block two, and is threadedly connected to the adjusting nut.

[0013] The present invention also provides a coating production process, which uses the coating production system described above to coat the surface of the belt to be coated.

[0014] The present invention also provides a graphene-coated aluminum plate, wherein the aluminum plate surface is coated by the coating production process described above.

[0015] In summary, the present invention has the following beneficial effects:

[0016] In this solution, the scraper has an upward-facing scraping blade that abuts against the belt to be coated, providing support for the belt, especially for the middle section of the belt. The scraper provides support and can maintain the relative uniformity of the middle section of the belt to a certain extent, thus alleviating the tension imbalance of the belt in the width direction.

[0017] The scraping blade in the middle section of the scraper can deform upwards, thus forming an upward arc-shaped bulge structure. This provides additional support to the middle part of the belt, allowing the pressure of the scraping blade, the edge of the belt, and the middle part of the belt to be close to each other. This balances the coating pressure at various positions along the width of the belt, thereby improving the uniformity of the coating. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] This embodiment discloses a coating production system, referring to... Figures 4-10 As shown, it includes a doctor blade mechanism. In the coating production process, the material is first applied to the surface of the belt 7 to be coated. Then, the doctor blade mechanism can scrape the material from the surface of the belt 7, thereby forming a coating layer of appropriate thickness on the surface of the belt 7.

[0031] The scraper mechanism includes a scraper 1 and an adjusting frame 2. The scraper 1 has an upward-facing scraping blade 101, which is used to abut against the belt 7 to be coated. (Refer to...) Figures 1-3 As shown, in this embodiment, the scraper mechanism is located on the lower surface of the belt body 7, which can support the belt body 7, especially the middle part 702 of the belt body 7, and can alleviate the tension imbalance of the belt body 7 in the width direction to a certain extent.

[0032] Reference Figure 2 In theory, the scraping blade 101 of the scraper mechanism needs to be in contact with the lower surface of the belt body 7; however, when the width of the belt body 7 is long, for example, more than 2m, the belt body 7 will form a structure with a middle overhang in the width direction, that is, it is in a relatively tight state near the edge 701 of the belt body, while the middle part 702 of the belt body is in a relatively loose state.

[0033] During the coating process, the pressure between the scraper blade 101 and the edge 701 of the belt body is relatively large, while the pressure between the scraper blade 101 and the middle part 702 of the belt body is relatively large, resulting in a slightly thicker coating thickness in the middle part 702 of the belt body. Especially when the scraper 1 is located on the upper side of the belt body 7, since the lower side of the belt body 7 is not supported, the effect of the slack and drooping of the middle part 702 of the belt body will be greater. By setting the scraper 1 on the lower side of the belt body 7, the scraper 1 can provide support and maintain the relative uniformity of the middle part 702 of the belt body to a certain extent.

[0034] In this embodiment, an installation position 202 suitable for installing the adjustment frame 2 is formed on the adjustment frame 2, and the scraper 1 is provided at the installation position 202 of the adjustment frame 2.

[0035] The installation position 202 has an upward-facing lower support surface 2021. The lower support surface 2021 can press and support the lower side of the scraper 1, thereby limiting the bending deformation of the scraper 1 in the vertical direction and restricting the deformation direction of the arc-shaped bulge of the scraper 1.

[0036] The scraper 1 is divided into a middle section 103 and two side edge sections 104 along its length. The length of the middle section 103 is not less than 1m. The side edge sections 104 are slidably installed at the installation position 202 along the length of the scraper 1.

[0037] In this embodiment, the scraper 1 is capable of elastic bending. Because the scraper 1 is relatively tall vertically and thin horizontally, during elastic deformation, it primarily undergoes arc-shaped deformation in the horizontal direction. Furthermore, during this arc-shaped bending process, the lower side of the scraper 1 remains in contact with the lower support surface 2021. Specifically, the scraper 1 is made of a polymer material, such as rubber. An elastic padding layer 105 is laminated to the side of the scraper 1 facing away from the raised direction. This elastic padding layer 105 can be made of an elastic metal material, providing auxiliary support. Specifically, the elastic padding layer 105 can be a shape memory alloy.

[0038] During the adjustment process, by adjusting the position of the scraper edge sections 104 on both sides, the relative distance between the scraper edge sections 104 on both sides can be brought closer to each other, thereby enabling the scraper 1 (especially the middle section 103 of the scraper) to form an arc-shaped elastic deformation and form a bow-shaped structure.

[0039] Correspondingly, refer to Figure 5 As shown, the installation position 202 is divided into a middle section 203 and two side sections 204 along the length direction. An adjustment groove 207 is provided in the side section 204.

[0040] A slider 102 is fixedly connected to the edge section 104 of the scraper. The slider 102 is a rigid, non-deformable structure. The slider 102 can fix and support the edge section 104 of the scraper, preventing it from undergoing arc-shaped bending deformation. Furthermore, the shape of the slider 102 is adapted to the adjusting groove 207. The slider 102 is embedded in the adjusting groove 207 and is slidably connected to the adjusting groove 207.

[0041] Reference Figure 5 As shown, the middle section 203 of the installation position has a deformation notch on the input side facing the belt body 7, and the deformation notch allows the scraper 1 to bend and bulge elastically.

[0042] Reference Figure 9 , Figure 10 As shown, in this embodiment, the scraper mechanism further includes two sets of adjustment components 6, and the scraper edge section 104 and the adjustment frame 2 are adjusted by the adjustment components 6. Specifically, the adjustment components 6 include an adjustment block 601, an adjustment block 602, an adjustment screw 603 and an adjustment nut 604. The adjustment block 601 is fixedly installed on the outside of the adjustment frame 2, and the adjustment frame 2 is provided with an adjustment groove 207.

[0043] The adjusting groove 207 is set along the sliding direction of the slider 102, and an adjusting block 602 is slidably installed in the adjusting groove 207. One side of the adjusting block 602 is fixedly connected to the slider 102, and the other side extends to the outside of the adjusting frame 2. During the adjustment process, by adjusting the distance between the adjusting block 601 and the adjusting block 602, the adjusting block 602, the slider 102, and the scraper edge section 104 can be driven to adjust the position of the two scraper edge sections 104, thereby adjusting the arc-shaped bulge of the middle section 103 of the scraper.

[0044] Reference Figure 10 As shown, a through hole is provided in the second adjusting block 602. The adjusting screw 603 is fixedly connected to the first adjusting block 601 on one side. The other end of the adjusting screw 603 extends towards the end of the scraper 1 and passes through the second adjusting block 602. An adjusting nut 604 is threadedly connected to the end of the adjusting screw 603 away from the first adjusting block 601. By turning the adjusting nut 604, the distance between the first adjusting block 601 and the second adjusting block 602 can be adjusted, thereby adjusting the arc-shaped bulge of the middle section 103 of the scraper accordingly.

[0045] The adjusting frame 2 has rotating shafts 201 fixedly connected to both sides. The rotating shafts 201 are rotatably mounted on the frame, and their axis coincides with the unbent scraper blade 101. (Refer to...) Figure 8As shown, during the arc-shaped deformation process of the middle section 103 of the scraper, the deformation direction mainly occurs in the horizontal direction, and the scraper blade 101 at the middle section 103 of the scraper will also bend in an arc. After the middle section 103 of the scraper is bent in an arc, the entire scraper 1 is deflected, thereby causing the scraper 1 (scraper blade 101) to be deflected and adjusted; the scraper blade 101 of the middle section 103 of the scraper can be deformed upward, thereby causing part of the scraper blade 101 of the scraper 1 to form an upward arc-shaped bulge structure, which can provide supplementary support to the middle part 702 of the belt, so that the pressure of the scraper blade 101, the edge part 701 of the belt, and the middle part 702 of the belt can approach each other, thereby balancing the coating pressure at various positions in the width direction of the belt 7, and thus improving the uniformity of coating.

[0046] Reference Figure 4 , Figure 6 , Figure 7 As shown, the scraper mechanism also includes a support frame 3, which is fixedly installed on the machine frame. Support frame 3 is fixedly connected to support baffle 1 301 and support baffle 2 302 respectively, corresponding to the input and output sides of the adjusting frame 2. An adjustment gap 303 is formed between support baffle 1 301 and support baffle 2 302. The lower side of the adjusting frame 2 extends into the adjustment gap 303, and a spring 5 elastically presses against support baffle 1 301 and adjusting frame 2. Through the pressing action of spring 5, the adjusting frame 2 can be pressed against support baffle 2 302, allowing the adjusting frame 2 to maintain a relatively stable state; moreover, in the state where the adjusting frame 2 and support baffle 2 302 are pressed against each other, the lower support surface 2021 is horizontal.

[0047] Reference Figure 7 As shown, the second support baffle 302 is threadedly connected to a screw 4. One end of the screw 4 passes through the second support baffle 302 and can extend into the adjustment gap 303 between the first support baffle 301 and the second support baffle 302. By adjusting the screw 4, the end of the screw 4 can be brought into contact with the adjustment frame 2. By continuing to rotate the screw 4, the length of the screw 4 extending into the second support baffle 302 can be adjusted. Thus, the adjustment frame 2 can be tilted with the help of the screw 4. Under normal circumstances, the tilt range is within 5°.

[0048] During the tilting and deflection of the adjusting frame 2, the scraping blade 101 of the scraper 1 will deflect at an appropriate angle. Since the scraping blade 101 of the middle section 103 of the scraper is in a bent state, the arc-shaped raised part (especially the middle position of the scraper 1) can generate a certain arc-shaped raised part during the deflection of the adjusting frame 2, thereby applying a certain compensating pressure to the middle part 702 of the belt body, so that the force and coating state of the belt body 7 in the width direction remain relatively uniform and stable.

[0049] Because the axis of the rotating shaft 201 coincides with the unbent scraper blade 101, and because the scraper 1 undergoes bending deformation, the arcuate bulge near the center of the scraper 1 is larger, while the arcuate bulge near the two edges is smaller; and at the scraper edge section 104, the scraper 1 is restricted by the rigid slider 102 and cannot undergo direct deformation, therefore, the scraper blade 101 at the scraper edge section 104 remains in a straight line state. Therefore, during the rotation of the adjusting frame 2 and the scraper 1 axis, the height of the scraper blade 101 at the scraper edge section 104 does not change, meaning the pressure change corresponding to the pressure on the lower side of the belt edge 701 is small, and the pressure near the outermost edge hardly changes.

[0050] This embodiment also discloses a coating production process, which uses the coating production system described above to coat the surface of the belt 7 to be coated.

[0051] Reference Figure 1 As shown, during the coating process, the doctor blade 1 of the coating production system is set upwards, and the belt 7 passes over the upper side of the doctor blade 1. Before coating, the coating material is first applied to the surface of the belt 7 to roughly form a coating layer. Then, the scraping blade 101 of the doctor blade 1 of the coating production system presses against the surface of the coating layer of the belt 7 to coat it, thereby scraping off the excess coating material and forming a coating layer of uniform thickness on the surface of the belt 7.

[0052] During the coating process, the doctor blade 1 is bent and adjusted according to the edge 701 and the middle part 702 of the belt body 7, and the doctor blade 1 and the adjusting frame 2 are appropriately deflected. This can appropriately increase the pressure of the doctor blade 1 on the middle part 702 of the belt body, so that the pressure of the doctor blade on the middle part 702 and the edge 701 of the belt body can be kept in a relatively balanced and stable state.

[0053] This embodiment also discloses a graphene-coated aluminum plate. In the production process, the aluminum plate surface is first pretreated, then a base coating is applied, followed by a graphene coating. The coating is then cured to form the desired plate. The raw material for the aluminum plate is an aluminum coil structure, forming a strip-shaped aluminum plate. During the coating process, the aluminum plate surface is coated using the above-described coating production process, thereby maintaining the uniformity of the coating in the width direction of the aluminum plate and preventing the formation of an overly loose coating layer.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention.
