[0026] It should be understood that the embodiments of the present invention shown in the exemplary embodiments are merely illustrative. Although only a few embodiments of the present invention are described in detail, those skilled in the art can easily appreciate that various modifications are feasible without substantially departing from the teachings of the subject matter of the present invention. Accordingly, all such modifications should be included within the scope of the present invention. Without departing from the gist of the present invention, other substitutions, modifications, variations and deletions can be made to the design, operating conditions, parameters, etc. of the following exemplary embodiments.
[0027] Please refer to Figure 1 , Figure 1 which shows a flowchart of a method for preparing a color-coated board by shearing. A method 100 for preparing a color-coated board by shearing includes: Step a: longitudinally cut the color-coated board raw material coil into color-coated board strips; Specifically, the color-coated board raw material coil is longitudinally cut into color-coated board strips by a shearing and longitudinal cutting machine set. According to the various application fields and specific products of color-coated board shearing, such as household appliances such as refrigerators and washing machines in the household appliance field. During the process of longitudinally cutting the color-coated board raw material coil into color-coated board strips, it is necessary to longitudinally cut the color-coated board raw material coil into color-coated board strips of corresponding size specifications, and then flattening treatment is carried out in a transverse cutting machine set, and further cutting is carried out by a flying shear during the next process treatment. At the same time, in order to ensure the flatness of the board surface and the strip width deviation ≤ ±0.25 mm, there are certain requirements for the longitudinal cutting speed of the color-coated board for household appliances of the present invention. For example, for a raw material with a width of 845 mm, the longitudinal cutting speed ≤ 80 m / min, and for a raw material with a width of 1209 mm, the longitudinal cutting speed ≤ 70 m / min.
[0028] Specifically, the color-coated board raw material coil has different sizes and plate types. For example, the thickness of the color-coated board raw material coil for household appliances can be in the range of 0.4 - 0.8 mm, and there are various plate types for different plate type color-coated board raw material coils. Correspondingly, there are defect situations such as warping, waviness, wavy edges, and mild knife bending.
[0029] Step b: adjust the size of the shear blade gap of the flying shear according to the thickness of the raw material coil, cut the color-coated board strips into plates of target size by the flying shear, and adjust the reduction amount of the leveler according to the thickness of the raw material coil and the corresponding plate type defect situation, and flatten the surface of the plate by the leveler; Specifically, in this embodiment, the thickness of the raw material roll is 0.4 - 0.8 mm. The size of the shear blade gap of the flying shear is adjusted to be 0.25 - 0.8 mm according to the thickness of the raw material roll, and the size of the shear blade gap of the flying shear is positively correlated with the thickness of the raw material roll within the range of 0.25 - 0.8 mm. For example, when the thickness of the raw material roll is 0.4 mm, the size of the shear blade gap of the flying shear is adjusted to 0.25 mm; when the thickness of the raw material roll is 0.45 mm, the size of the shear blade gap of the flying shear is adjusted to 0.3 mm; when the thickness of the raw material roll is 0.8 mm, the size of the shear blade gap of the flying shear is adjusted to 0.5 mm. The color-coated board strips are cut into sheets with target sizes by the adjusted flying shear.
[0030] Specifically, the roll gap of the leveler is adjusted according to the sheet shape defects of the raw material roll. Taking the case where the raw material roll has warping or edge wave defects as an example, when the thickness of the raw material roll is 0.4 - 0.8 mm and the height of the warping or edge wave of the raw material roll is within the range of 0.01 - 0.3 mm, the roll gap of the leveler is adjusted to +0.5 - +1.8 mm according to the height of the warping or edge wave of the raw material roll. That is to say, the roll gap of the leveler is positively correlated with the height of the warping or edge wave of the raw material roll within the range of +0.5 - +1.8 mm. For example, when the thickness of the raw material roll is 0.4 mm and the height of the warping of the raw material roll is within the range of 0.01 - 0.2 mm, the roll gap of the leveler is adjusted to +0.5 mm; when the thickness of the raw material roll is 0.45 mm and the height of the warping of the raw material roll is within the range of 0.1 - 0.2 mm, the roll gap of the leveler is adjusted to +1 mm; when the thickness of the raw material roll is 0.8 mm and the height of the warping of the raw material roll is within the range of 0.1 - 0.2 mm, the roll gap of the leveler is adjusted to +1.5 mm; when the height of the warping of the raw material roll is within the range of 0.2 - 0.3 mm, the roll gap of the leveler is adjusted to +1.8 mm. It can be seen from the above that as the height of the warping of the raw material roll continuously increases, the corresponding adjustment amount of the roll gap of the leveler also gradually increases.
[0031] Step c: Adjust the pressure range of the pressure roller of the laminating machine according to the peeling force range of the attached film, and laminate the attached film onto the surface of the leveled sheet through the laminating machine to obtain a color-coated board shear.
[0032] Specifically, the attached film includes a PE (Polyethylene) film. The PE film is a transparent plastic film material with good flexibility, moisture resistance, and chemical corrosion resistance. The attached film can protect the surface of the pre-painted sheet from damage, prevent scratching and abrasion, etc. It can also improve the gloss and appearance quality of the pre-painted sheet, and has protective effects such as waterproof, anti-fouling, and wear-resistant. Adjust the pressure range of the pressure roller of the laminating machine according to the peeling force range of the attached film, and laminate the attached film on the surface of the sheet after guiding and leveling through the laminating machine. For example, in a specific embodiment, the peeling force range of the easily tearable attached film is 100 - 300 N / m, and the peeling force range of the difficult-to-tear attached film is 400 - 750 N / m. Since the peeling force of the attached film is related not only to the characteristics of the attached film itself but also to the pressure of the pressure roller of the laminating machine, for the easily tearable attached film, adjust the pressure of the pressure roller of the laminating machine to 0.2 - 0.3 Kpa; for the difficult-to-tear attached film, adjust the pressure of the pressure roller of the laminating machine to 0.4 - 0.6 Kpa.
[0033] A method for preparing a cut sheet of pre-painted sheet according to the present invention effectively improves problems such as scratches, indentations, uneven stacking, color difference, horizontal stripes, stains, etc. on the sheet surface by adjusting the size of the shear blade gap of the flying shear, the reduction amount of the leveler, and the pressure range of the pressure roller of the laminating machine during the preparation process of the cut sheet of pre-painted sheet. It improves the qualified rate of the cut sheet products of pre-painted sheet produced by the factory, reduces the scrap rate, thereby reducing the production cost of the enterprise, and is beneficial for the enterprise to reduce costs and increase efficiency.
[0034] According to several embodiments of the present invention, the method further includes: Step d, adjust the power of the variable-frequency fan of the stacker according to the thickness of the raw material roll, and stack the attached cut pre-painted sheet through the stacker.
[0035] Specifically, the stacker is an air-cushion type combined with a ball-bearing receiving and dropping plate structure. In order to protect the plates from being scratched, the variable-frequency motor of the stacker drives the fan to supply air, which can ensure the formation of a reliable air cushion when the stacker is working. At the same time, it can also isolate adjacent sheet pieces to protect the sheet surface. Adjust the power of the variable-frequency fan according to the thickness of different raw material rolls, and the air volume of the variable-frequency fan can be manually adjusted. In a specific example, the thickness of the raw material roll is 0.4 - 0.8 mm, and the power of the variable-frequency fan is adjustable within the range of 1.5 - 3.7 KW. For example, when the thickness of the raw material roll is 0.4 mm or 0.45 mm, adjust the power of the variable-frequency fan to 1.5 - 3 KW; when the thickness of the raw material roll is 0.8 mm, adjust the power of the variable-frequency fan to 3 - 3.7 KW. It can be seen from the above that as the thickness of the raw material roll continuously increases, the power of the variable-frequency fan of the stacker also gradually increases.
[0036] According to another specific embodiment of the present invention, please refer to Figure 2, A method for preparing a color-coated sheet by shearing includes: First, use a crane to lift the coil to the mobile stock preparation table for storage. Then, use the loading trolley to manually place the coil on the mandrel of the uncoiler and tighten and fix it. With the assistance of the leading guide plate and pressure rollers, the coil is slowly unwound. Subsequently, straighten the head of the coil and introduce it into the pinch rolls. Through the stable conveyance of the pinch rolls, the sheet is smoothly sent to the next process. After the sheet is sent in, first cut off its head. Then, with the help of a six-roll 19-roll cassette straightener, accurately straighten different types of strip steel to ensure the flatness of the strip steel. The straightened strip steel then enters the film laminator to protect its surface by laminating. The laminated strip steel enters the feeding and measuring device, which synchronously completes the feeding operation and accurately measures the length and speed of the strip steel. The sheet sent out from the feeding device is cut to a fixed length according to the set size and processed into a rectangle. After that, the finished sheet is placed on the conveyor belt and transferred by belt transportation. During this process, use a lift to adjust the height of the falling sheet to ensure the smooth fall of the sheet. Finally, use a stacker to orderly collect the transported finished sheets to complete the entire process of preparing the color-coated sheet by shearing.
[0037] According to several embodiments of the present invention, step d includes: According to the thickness of the raw material coil being 0.4 - 0.8 mm, adjust the power of the variable-frequency fan of the stacker to 1.5 - 3.7 KW, where the power of the variable-frequency fan of the stacker is positively correlated with the thickness of the raw material coil.
[0038] According to several embodiments of the present invention, step b includes: According to the thickness of the raw material coil being 0.4 - 0.8 mm, adjust the size of the shear blade gap of the flying shear to 0.25 - 0.8 mm, where the size of the shear blade gap of the flying shear is positively correlated with the thickness of the raw material coil.
[0039] According to several embodiments of the present invention, step b further includes: According to the thickness of the raw material coil being 0.45 mm, adjust the size of the shear blade gap of the flying shear to 0.3 mm; according to the thickness of the raw material coil being 0.8 mm, adjust the size of the shear blade gap of the flying shear to 0.5 mm.
[0040] According to several embodiments of the present invention, step b further includes: According to the thickness of the raw material coil being 0.4 - 0.8 mm and the height of the warp or edge wave of the raw material coil being 0.01 - 0.3 mm, adjust the roll gap of the precision straightener to +0.5 - +1.8 mm, where the adjustment amount of the roll gap is positively correlated with the height of the warp or edge wave.
[0041] According to several embodiments of the present invention, step b further includes: According to the thickness of the raw material coil being 0.4 mm and the height of the warp of the raw material coil being 0.01 - 0.2 mm, adjust the roll gap of the precision straightener to +0.5 mm.
[0042] According to several embodiments of the present invention, step b further includes: adjusting the roll gap of the precision straightening machine to +1.8 mm based on the thickness of the raw material roll being 0.8 mm and the height of the wavy edge of the raw material roll being 0.1 - 0.3 mm.
[0043] According to several embodiments of the present invention, step c includes: adjusting the pressure range of the pressure roller of the laminating machine to 0.2 - 0.3 Kpa based on the peel force range of the attached film being 100 - 300 N / m.
[0044] According to several embodiments of the present invention, step c further includes: adjusting the pressure range of the pressure roller of the laminating machine to 0.4 - 0.6 Kpa based on the peel force range of the attached film being 400 - 750 N / m.
[0045] For a further understanding of a method for preparing a cut sheet of color-coated sheet according to the present invention, please refer to Figure 1-2 and the following will be further elaborated in detail in specific embodiments.
[0046] In the embodiments, cases are given where the thicknesses of the raw material rolls are 0.4 mm, 0.45 mm, and 0.8 mm respectively, the fly shear blade gaps are 0.25 mm, 0.3 mm, and 0.5 mm respectively, the wavy edge / warp height is in the range of 0.01 - 0.3 mm, the peel degree of the attached film is an easy-to-peel film (peel force range is 100 - 300 N / m) or a difficult-to-peel film (peel force range is 400 - 750 N / m), the roll gap of the precision straightening roller is in the range of +0.5 - +1.8 mm, the pressure of the pressure roller of the laminating machine is in the range of 0.2 - 0.6 Kpa, and the power of the variable-frequency blower is in the range of 1.5 - 3.7 KW, corresponding to Embodiments 1 to 10. Among them, the specific process parameters of Embodiments 1 to 10 are shown in Table 1 below: Table 1
[0047] The flatness, glossiness, presence or absence of appearance defects, incision burrs, and whether the attached film meets the requirements of being easy to peel or difficult to peel of the cut sheets of color-coated sheets corresponding to Embodiments 1 to 10 are compared to determine whether the cut sheets of color-coated sheets obtained by the method for preparing a cut sheet of color-coated sheet of this application are qualified, as shown in Table 2 specifically: Table 2
[0048] As can be seen from the comparison between Table 1 and Table 2 above, according to the thickness of the raw material coil in the range of 0.4 - 0.8 mm, the size of the flying shear blade gap is adjusted correspondingly within the range of 0.25 - 0.8 mm, and the power of the variable-frequency fan of the stacker is adjusted correspondingly within the range of 1.5 - 3.7 KW. Combining with the thickness of the raw material coil in the range of 0.4 - 0.8 mm and the wave edge / warp height in the range of 0.01 - 0.3 mm, the reduction amount of the precision leveling roll is adjusted correspondingly within the range of +0.5 - +1.8 mm. According to whether the attached film is an easy-to-tear film or a difficult-to-tear film, the pressure of the laminating machine pressure roller is adjusted correspondingly within the range of 0.2 - 0.6 Kpa. In addition, the shearing of the household appliance color-coated board also meets other qualified requirements, with the width deviation ≤ ±0.25 mm, the length deviation in the range of -0.5 - 0 mm, and the diagonal deviation in the range of 0 - 0.5 mm. By adjusting the size of the flying shear blade gap, the reduction amount of the precision leveling machine, and the pressure range of the laminating machine pressure roller during the preparation process of the color-coated board shearing, problems such as scratches, imprints, uneven stacking, color difference, horizontal stripes, and stains on the board surface are effectively improved, making the finally obtained color-coated board shearing have good flatness, good gloss, no appearance defects (such as no wave edge / warp defects), the incision burr ≤ 0.1 mm, and meet the requirements of easy-to-tear film or difficult-to-tear film.
[0049] In actual industrial production, the qualified rate of the color-coated board shearing prepared by existing factories is 84.8%. Applying the method for preparing the color-coated board shearing of the present application to industrial production, the qualified rate of the prepared color-coated board shearing reaches 91%. In the household appliance color-coating industry, the total annual household appliance color-coating volume is expected to be about 20,000 tons. Based on the method for preparing the color-coated board shearing of the present application, the qualified rate of the household appliance color-coated board shearing is increased by at least 6.2 percentage points, and it is expected to reduce the cost loss of the factory by only 1 million yuan. A method for preparing a color-coated board shearing of the present application improves the qualified rate of the color-coated board shearing products produced by the factory, reduces the waste rate, thereby reducing the production cost of the enterprise, and is beneficial for the enterprise to reduce costs and increase efficiency.
