Description

Technical Field

[0001] This invention belongs to the field of color-coated coil technology, and specifically relates to a dust removal device for pretreatment of color-coated coil substrate. Background Technology

[0002] Color-coated steel coils are products made from metal sheets such as hot-dip galvanized steel sheets, hot-dip aluminized zinc steel sheets, and electro-galvanized steel sheets as substrates. After surface pretreatment processes such as chemical degreasing and chemical conversion treatment, one or more layers of organic coating are uniformly applied to the surface, followed by a baking and curing process. Because of the richly colored organic coating on its surface, it is called color-coated steel coil, or simply color-coated coil. With its excellent properties such as corrosion resistance, lightweight and high strength, easy processing and molding, and outstanding decorative properties, this material has been widely used in many industries: In the construction industry, color-coated coils are often used as roofing and wall materials for large buildings such as industrial plants, warehouses, and stadiums. They are also suitable for interior partitions, ceilings, and the enclosure structure of steel structure houses, achieving a perfect unity of functionality and aesthetics. In the home appliance industry, color-coated coils are the preferred material for the outer shells of home appliances such as refrigerators, washing machines, and air conditioners. Their surface is smooth and flat, highly corrosion-resistant, and easy to clean. The coatings used in some high-end products also have special functions such as anti-fingerprint and antibacterial properties, further improving product quality and user experience. In the transportation industry, color-coated coils are widely used in the manufacture of components such as automobile bodies, rail transit interiors, and ship linings, fully meeting the stringent requirements of lightweight design, impact resistance, and resistance to salt spray corrosion.

[0003] In existing color-coated coil production technology, dust removal equipment in the substrate pretreatment stage still faces many problems that urgently need to be solved. Currently, commonly used dust removal equipment for color-coated coil substrate pretreatment mainly adopts traditional treatment methods such as dust blowing and water washing. When oily dust adheres to the substrate surface, water washing can effectively remove oil stains, but it is very easy to leave water stains on the substrate surface. These water stains make the substrate surface damp, which will not only re-adsorb dust during subsequent transportation due to adsorption force, placing extremely stringent requirements on the production environment, but also significantly reducing the pretreatment efficiency of color-coated coils. More seriously, if the residual water stains are not treated in time, they will become a potential hazard for rust stains, seriously affecting the product quality and service life of color-coated coils. In addition, existing water stain removal equipment also has obvious defects in practical applications. It is difficult to achieve real-time cleaning of accumulated moisture, resulting in a large number of ineffective operations, increasing production costs and time losses; or it requires frequent replacement of consumables that absorb water stains, making the operation cumbersome and greatly reducing the overall ease of use and production efficiency of color-coated coil substrate pretreatment dust removal equipment.

[0004] Therefore, it is necessary to invent a dust removal device for pretreatment of color-coated roll substrate to solve the above problems. It can quickly and continuously remove dust and residual water stains, thereby improving the pretreatment efficiency of color-coated roll substrate. Summary of the Invention

[0024] As a specific embodiment of the present invention, a cleaning fluid control mechanism 5 is connected to the side of the inner wall of the support and protective frame 101.

One end of each of the two flow tubes 501 is connected to a connecting hose 504. A cleaning fluid guide pump 503 is fixedly provided at the top of the support and protective frame 101. One end of each of the two connecting hoses 504 is connected to the cleaning fluid guide pump 503. When performing dust removal on the color-coated roll substrate, the cleaning liquid is sprayed out through the connecting hose 504, flow pipe 501 and cleaning liquid nozzle 502 by the cleaning liquid guide pump 503 fixed at the top of the support and protective frame 101, so that the cleaning liquid directly acts on the surface of the color-coated roll substrate for water washing and dust removal.

[0025] As a specific embodiment of the present invention, a dust removal adjustment mechanism 3 is connected to the other side of the inner wall of the dust removal support and protection mechanism 1, and a dust removal linkage mechanism 6 is connected to the inner wall of the dust removal adjustment mechanism 3. In one specific embodiment of the present invention, the dust removal adjustment mechanism 3 includes two positioning frames 301, each of which is fixedly provided with a positioning platform 302 at both ends. Each of the four positioning platforms 302 is fixedly provided with a positioning rod 303 at both ends on one side. Each of the eight positioning rods 303 has a return spring 304 inserted through one end of its outer wall and a positioning block 305 fixedly provided at one end of its outer wall. Each of the two positioning frames 301 has a fixing groove 306 at both ends. Each of the two fixing grooves 306 has a lifting seat 307 slidably connected to one end of its inner wall. The other ends of the eight positioning rods 303 are respectively inserted through the two ends of the four lifting seats 307. In one specific embodiment of the present invention, the dust removal linkage mechanism 6 includes two lifting frames 601. The two ends of the two lifting frames 601 pass through four fixing slots 306 and are fixedly connected to one side of four lifting seats 307. Multiple linkage gears 602 are rotatably connected to one side of each of the two lifting frames 601. The teeth of the multiple linkage gears 602 mesh with each other sequentially. One end of each of the multiple linkage gears 602 passes through the two lifting frames 601 and is fixedly mounted on a rotating frame 603. A cleaning brush 604 is fixedly mounted on one side of each of the multiple rotating frames 603. Fixed gears 610 are meshed with the teeth of each of the two linkage gears 602. A fixed seat 611 is fixedly provided on one side of 610. The outer walls of the two fixed seats 611 are rotatably connected to one end of the two lifting frames 601 respectively. A limiting seat 606 is fixedly connected to the middle position of one side of a positioning frame 301. A connecting shaft 607 is rotatably connected to the middle position of the limiting seat 606. Three positioning strips 608 are fixedly provided at both ends of the outer wall of the connecting shaft 607. The two ends of the outer wall of the connecting shaft 607 are respectively inserted and connected to the inner walls of the two fixed seats 611 through the positioning strips 608. A connecting block 609 is fixedly provided at both ends of the connecting shaft 607. One side of the multiple cleaning brushes 604 respectively contacts both sides of the color-coated roll substrate 2. A geared motor 605 is fixedly installed at one end of the top of the support frame 101, and the output end of the geared motor 605 is fixedly connected to one end of one of the connecting blocks 609. The output end of the geared motor 605 fixed to the top of the support frame 101 drives the connecting shaft 607 to rotate. The positioning strip 608 fixed to the outer wall of the connecting shaft 607 limits the rotation of the fixed gears 610 inserted on both sides of the outer wall of the connecting shaft 607. One end of the fixed gear 610 is rotatably connected to the lifting frame 601 through the fixed base 611. The fixed gear 610 meshes with the connected linkage gear 602, and the sequentially connected linkage gears 602 are connected for transmission. Multiple linkage gears 602 pass through the two lifting frames 601 respectively to drive multiple rotating frames 603 and cleaning brushes 604 to rotate. Since the adjacent rotating frames 603 are staggered, every part of the color-coated roll substrate is cleaned, avoiding missed areas. At the same time, through the linkage of the connecting shaft 607, one electrical appliance drives multiple rotating frames 603 and cleaning brushes 604 to work synchronously, maintaining the stability of the operation and reducing production costs. Multiple cleaning brushes 604 rotate alternately under the drive of the linkage gear 602, ensuring that every part of the substrate is thoroughly cleaned and avoiding missed areas; at the same time, the cleaning liquid control mechanism 5 sprays cleaning liquid through the cleaning liquid nozzle 502, further enhancing the cleaning effect. Since the lifting seats 307 fixed at both ends of the lifting frame 601 pass through the fixing slots 306 opened on the positioning frame 301, and the lifting seats 307 are interlocked with the positioning rods 303 fixed on one side of the positioning platform 302, the elastic deformation of the return spring 304 interlocked on the outer wall of the positioning rod 303 and the positioning of the positioning block 305 enable the lifting seats 307 to drive the lifting frame 601, the rotating frame 603 and the cleaning brush 604 to fit tightly against the outer wall of the color-coated roll substrate when cleaning color-coated roll substrates of different thicknesses. Furthermore, the fixed gears 610 and the fixed seats 611 are interlocked with the connecting shaft 607 and the positioning strip 608 to avoid affecting the relative position of the lifting frame 601, so that the color-coated roll substrate is thoroughly cleaned, avoiding the adsorption of oily dust and stubborn dust, and improving the cleaning efficiency of the color-coated roll substrate.

[0026] The dust removal and cleaning control mechanism 4 includes four drive shafts 401 that rotate on the inner wall of the support and protective frame 101. Cleaning drive belts 402 are connected to each other on the outer walls of the four drive shafts 401. Two guide frames 403 are fixedly connected to the inner wall of the support and protective frame 101 near the drive shafts 401. A positioning shaft 404 is rotatably connected to the middle position of the inner wall of each guide frame 403. Limiting shafts 405 are rotatably connected to both ends of the top of each guide frame 403. A pressing shaft 406 is rotatably connected to both ends of the middle position of the inner wall of each guide frame 403. Positioning gears 409 are fixedly connected to both ends of the two drive shafts 401 through the support and protective frame 101. The teeth of the four positioning gears 409 mesh with each other in pairs. One end of each of the two guide frames 403 is connected to one end of each of the two guide tubes 108. A positioning seat 407 is fixedly connected to the bottom end of one side of the outer wall of the support and protective frame 101. A drive motor 408 is fixedly installed on one side of the positioning seat 407. The output end of the drive motor 408 is fixedly connected to the middle position of one of the positioning gears 409. After the pre-coated steel roll substrate has been washed and assisted in cleaning, it is passed through the outer walls of two sets of cleaning conveyor belts 402, ensuring that the two cleaning conveyor belts 402 make full contact with both sides of the pre-coated steel roll substrate. The output end of the drive motor 408, fixed to one side of the positioning seat 407, drives one of the positioning gears 409 to rotate. The teeth of the four positioning gears 409 mesh in pairs, causing both sets of drive shafts 401 to rotate against the direction of movement of the pre-coated steel roll substrate. This results in the cleaning conveyor belts 402 moving in the opposite direction to the pre-coated steel roll substrate, ensuring that the last part of the cleaning conveyor belt 402 to contact the substrate is the cleanest. The belts continue moving forward until they are fully saturated with residual moisture on the surface of the pre-coated steel roll substrate. At this point, the cleaning conveyor belt 402 passes through the limiting shaft 405. The limit transmission reaches the bottom of the positioning shaft 404, where two extrusion shafts 406, in close contact with the outer wall of the positioning shaft 404, expel water, ensuring that the cleaning transmission belt 402 remains in the driest possible state when in contact with the color-coated roll substrate. In actual production, this device reduces repeated processing and ineffective operations caused by water residue, thus improving production efficiency. Simultaneously, since frequent replacement of consumables is unnecessary, production costs are further reduced. This process repeats, ensuring that the surface of the color-coated roll substrate is thoroughly cleaned of water residue left from dust removal, and maintaining continuous dust removal without frequent consumable replacements. It also avoids ineffective pre-treatment operations caused by ineffective water removal, keeping the color-coated roll substrate dry after dust removal and preventing the re-adsorption of impurities and dust, thereby increasing the working efficiency of the color-coated roll substrate pre-treatment dust removal device. To address the issue of rust stains that may be caused by water residue, this device is designed to completely remove water stains from the substrate surface, effectively improving the product quality and service life of color-coated coils. In practical applications, this device significantly reduces rust problems caused by water residue, improves the corrosion resistance and overall quality of color-coated coils, and thus extends the product's service life.

[0027] In one specific embodiment of the present invention, an intelligent control panel is fixedly provided on one side of the support and protective frame 101. The geared motor 605, the drive motor 408 and the cleaning fluid guide pump 503 are all electrically connected to an external power supply through the intelligent control panel.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
