Abstract
Description
Technical Field
[0001] This utility model relates to the field of R-PUF foam board production, and in particular to a continuous fiberglass mat opening device. Background Technology
[0002] In continuous production lines for R-PUF foam boards, the bulkiness of glass fiber significantly impacts the impregnation of polyurethane raw materials. Higher glass fiber bulkiness facilitates full impregnation, resulting in better physical properties of the foam and ultimately, better glass fiber distribution and performance in the R-PUF product. Currently, suppliers produce glass fiber with poor bulkiness, severely affecting raw material permeability during R-PUF production and leading to substandard final product performance. Existing opening devices typically use punching rollers, but the traditional punching roller structure disrupts the uniformity of glass fiber distribution on each layer and results in a microscopic mesh structure in the glass fiber mat after opening, negatively affecting product performance. Therefore, a new technical solution is urgently needed to address these issues. Summary of the Invention

[0020] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0021] Please refer to Figures 1-3 This utility model includes:
[0022] A continuous fiberglass mat opening device includes symmetrically arranged mounting bases 1, with a first roller 2 and a second roller 3 between the two mounting bases 1. A plurality of first rollers 4 are mounted on the first roller 2, and a plurality of second rollers 5 are mounted on the second roller 3. The first roller 2 and the second roller 3 are arranged in parallel, and the first rollers 4 and the second rollers 5 are installed at intervals. The distance between the axes of the first roller 2 and the second roller 3 is equal to the sum of the radii of the first rollers 4 and the second rollers 5. In this embodiment, the mounting base 1 is fixed on the ground to make the fiberglass felt 7 more stable when it is loosened. The first roller 2 is installed directly above the second roller 3. The arrangement of multiple first rollers 4 and second rollers 5 can improve the loosening efficiency of the loosening device. In order to achieve the alternating installation of the first rollers 4 and the second rollers 5, the difference between the number of the first rollers 4 and the second rollers 5 is one. Whether the number of the first rollers 4 is one more than the number of the second rollers 5 or the number of the second rollers 5 is one more than the number of the first rollers 4, the purpose is to achieve the alternating installation of the first rollers 4 and the second rollers 5. By making the outer diameter circles of the first rollers 4 and the second rollers 5 tangent, the first rollers 4 and the second rollers 5 can compress the fiberglass felt 7, making the fiberglass felt 7 more fluffy. This avoids the problem that the gap between the outer diameter circles of the two rollers will result in unsatisfactory fluffiness or failure to provide the loosening effect after loosening, and the problem that partial overlap will generate a large shear force on the fiberglass, causing the fiberglass to slip down at the bent tip, resulting in unevenness of the entire plane.
[0023] Furthermore, the first rollers 4 are evenly spaced on the first roller 2, and the second rollers 5 are evenly spaced on the second roller 3. In this embodiment, the equal spacing of the first rollers 4 and the second rollers 5 ensures that the fluffiness of the loosened portion of the fiberglass felt 7 is consistent after it is loosened.
[0024] Furthermore, the distance between the two adjacent sides of the first roller 4 and the second roller 5 is greater than or equal to the thickness of the fiberglass felt 7. In this embodiment, the distance d between the sides of the first roller 4 and the second roller 5 is modified according to different thicknesses of the fiberglass felt 7. By interlacing and pressing the fiberglass felt 7, it macroscopically presents a wavy effect, increasing the overall thickness of the loosened portion and making the overall fluffiness higher.
[0025] Furthermore, there are nine first rollers 4 and eight second rollers 5, with the second rollers 5 installed between two adjacent first rollers 4.
[0026] Furthermore, a spacing adjustment component 6 is provided on the mounting base 1. The second roller 3 is fixed on the spacing adjustment component 6, and the distance between the first roller 2 and the second roller 3 is adjusted by the spacing adjustment component 6. In this embodiment, the mounting base 1 is provided with a waist hole (not shown in the figure). The connection end of the second roller 3 and the mounting base 1 can move within the waist hole of the mounting base 1 through the spacing adjustment device, so that the outer diameter circles of the first roller 4 and the second roller 5 are tangent, which also facilitates the installation of the fiberglass felt 7 during processing.
[0027] Furthermore, the spacing adjustment assembly 6 includes a spacing adjustment plate 61, a spacing adjustment bolt 62 between the mounting base 1 and the spacing adjustment plate, and the second roller 3 is fixed on the spacing adjustment plate 61. In this embodiment, adjusting the spacing adjustment bolt 62 causes the spacing adjustment plate 61 to move on the mounting base 1.
[0028] Furthermore, the mounting base 1 includes a first base plate 11 and a second base plate 12 perpendicular to the first base plate 11. The second base plate 12 has a mounting groove on the side away from the other mounting base 1, and the spacing adjustment plate 61 is disposed in the mounting groove. In this embodiment, the first roller 2, the second roller 3, and the spacing adjustment plate 61 are all installed in the mounting groove, and the spacing adjustment plate 61 moves within the mounting groove. The design of the mounting groove reduces the overall thickness while being more aesthetically pleasing.
[0029] Furthermore, the spacing adjustment plate 61 includes a first adjustment plate and a second adjustment plate perpendicular to one end of the first adjustment plate. The second roller 3 passes through the second base plate 12 and is connected to the second adjustment plate. The spacing adjustment bolt 62 passes through the first adjustment plate and is connected to the first base plate 11. In this embodiment, the spacing adjustment plate 61 is L-shaped. The L-shaped spacing adjustment plate 61 allows for easier height adjustment. The first adjustment plate is installed in the mounting groove, and the second mounting adjustment plate extends out of the mounting groove and is parallel to the second base plate 12. The spacing adjustment plate 61 can be moved by adjusting the second adjustment plate using the spacing adjustment bolt 62.
[0030] Furthermore, the spacing adjustment bolt 62 includes a bolt passing through the first adjustment plate and fixed on the first base plate 11, and a limiting nut disposed between the first adjustment plate and the first base plate 11. In this embodiment, each spacing adjustment plate 61 is provided with two spacing adjustment bolts 62, the first base plate 11 is provided with a threaded hole that mates with the bolt, the bolt is vertically fixed on the first base plate 11, and the limiting nut can limit and fix the position of the spacing adjustment plate 61.
[0031] Furthermore, both the first roller 2 and the second roller 3 are fixed to the mounting base 1. A bearing is provided between the first roller 4 and the first roller 2, and a bearing is provided between the second roller 5 and the second roller 3. In this embodiment, the first roller 2 and the second roller 3 are fixed to the mounting base 1 by threaded connection, and the first roller 4 and the second roller 5 can rotate on the first roller 2 and the second roller 3 respectively through the bearings. In another embodiment, bearings can also be installed between the first roller 2 and the second roller 3 and the mounting base 1, so that the first roller 2 and the second roller 3 can rotate on the mounting base 1. It can be understood that the processing of the fiberglass felt 7 can be completed even if the rollers and rollers do not rotate; the rotation of the rollers and rollers is to simplify the processing.
[0032] In summary, during the processing of fiberglass mat 7, the fiberglass mat 7 is placed between the first roller 4 and the second roller 5. The edges of the outer diameter circles of the first roller 4 and the second roller 5 are made tangent by adjusting the spacing adjustment plate 61 assembly, simultaneously clamping the fiberglass mat 7. At this point, a gap exists between the first roller 4 and the second roller 5. An external force causes the fiberglass mat 7 to move perpendicularly between the first roller 4 and the second roller 5. Under the extrusion pressure of the first roller 4 and the second roller 5, the fiberglass mat 7 is loosened, making the originally flat and dense continuous fiberglass mat 7 more fluffy. To prevent damage to the fiberglass mat 7 from the first roller 4 and the second roller 5, the first roller 4 and the second roller 5 are made of wear-resistant soft plastic. The overall structure, through the extrusion pressure of the rollers, improves the problem of poor raw material penetration caused by insufficient fluffiness of the continuous fiberglass mat 7, thereby enhancing the product performance level and manufacturing stability of the fiberglass mat 7.
