[0001] This application relates to the field of plastic sheet production equipment technology, and in particular to a cooling bracket for a wide-width thick sheet production line. Background Technology

[0002] In the production of wide and thick plates, the plate temperature is high after forming, requiring sufficient cooling and setting to ensure dimensional stability and physical properties. Existing production lines typically use long-distance cooling brackets to support and cool the plates. However, for wide and thick plates, especially those with significant thickness, their weight makes them prone to sagging, deformation, or surface scratches during cooling due to improper support. Insufficient cooling can also affect product quality. Furthermore, existing cooling bracket structures are fixed, making it difficult to adapt to the production needs of plates with different thicknesses or widths, resulting in inconvenient adjustments and requiring improved cooling efficiency. Summary of the Invention

[0023] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, structure, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0024] This application provides a cooling bracket for a wide-width, thick plate production line, such as... Figure 1 , 3 As shown, the wide-width thick plate production line includes a three-roll calender 20, a thick plate forming machine 30, and a traction machine 40 arranged sequentially from front to back. The three-roll calender 20 calenders the thick plate, and the thick plate forming machine 30 is used to temper and shape the thick plate output from the three-roll calender 20. The cooling bracket 10 of this application is connected between the thick plate forming machine 30 and the traction machine 40, so that the thick plate output from the thick plate forming machine 30 is cooled and transported on the cooling bracket 10. The traction machine 40 provides a front-to-back traction force for the thick plate on the rear side of the cooling bracket 10.

[0025] The cooling bracket 10 includes a first bracket 1 and three second brackets 2 that are connected sequentially from front to back. The front end of the first bracket 1 is connected to the outlet of the plate forming machine 30, the rear end of the first bracket 1 is connected to the front end of the adjacent second bracket 2, and the rear end of the last second bracket 2 is connected to the inlet of the traction machine 40.

[0026] like Figure 1-4 As shown, the first bracket 1 includes a first outer frame 11 and first cooling rollers 12 arranged at intervals from front to back on the first outer frame 11. The two ends of each first cooling roller 12 are rotatably mounted on the left and right side beams of the first outer frame 11 via bearings. In this embodiment, the first cooling roller 12 is preferably an aluminum roller with a diameter of 90mm-110mm. The smaller diameter aluminum roller is lightweight and has fast heat conduction, which is beneficial for the rapid initial cooling of the thick plate exported from the thick plate forming machine 30, and the cooling efficiency is higher.

[0027] like Figure 3 , 5As shown in Figure 6, the second bracket 2 includes a second outer frame 21 and two rows of second cooling rollers 22 rotatably mounted on the second outer frame 21. The two rows of second cooling rollers 22 are respectively arranged on the left and right halves of the second outer frame 21, with each row of second cooling rollers 22 spaced apart from front to back. The second outer frame 21 includes a left support beam 211, a middle support beam 212, and a right support beam 213 arranged sequentially from left to back. The left support beam 211, the middle support beam 212, and the right support beam 213 are parallel to each other. The two ends of one row of second cooling rollers 22 are rotatably mounted on the left support beam 211 and the middle support beam 212, respectively, and the two ends of the other row of second cooling rollers 22 are rotatably mounted on the right support beam 213 and the middle support beam 212, respectively. These two rows of second cooling rollers 22 are arranged alternately from front to back on the second outer frame 21. In this embodiment, the second cooling roller 22 is preferably a galvanized steel roller. Galvanized steel rollers are inexpensive, high-strength, and wear-resistant, making them suitable for long-distance support and continuous cooling, thus making the entire cooling bracket more economical. The diameter of the second cooling roller 22 is 50mm-70mm, and its length is less than that of the first cooling roller 12. This allows each row of second cooling rollers 22 to support a portion of the width of the plate. This alternating support method provides sufficient and stable support to prevent the middle of the wide and thick plate from sagging, reduces the contact area between the plate and the roller, lowers the risk of scratches, and facilitates airflow at the bottom of the plate, improving cooling uniformity and efficiency. The series connection of the first bracket 1 and the second bracket 2 from front to back can adapt to the cooling needs and stress states of wide and thick plates at different stages, effectively improving product quality.

[0028] like Figure 1 , 6 As shown in Figure 7, each second bracket 2 is supported by multiple sets of support legs 3 arranged at intervals from front to back. Each set of support legs 3 includes three support legs 3 arranged side by side along the left-right direction below the left support beam 211, the middle support beam 212, and the right support beam 213 to enhance the stability of the second bracket 2. To ensure the flat transport of the thick plate, the first bracket 1 and the three second brackets 2 need to be flush. The top of the support legs 3 of each second bracket 2 is equipped with a lifting adjustment component 4. The height of the second bracket 2 is adjusted by the lifting adjustment component 4 to make the thick plate transition smoothly between the brackets. The lifting adjustment component 4 includes a lifting screw 41 extending in the vertical direction and a connecting member 42 that cooperates with the top end of the lifting screw 41. The lifting screw 41 passes through the corresponding support leg 3 and is threadedly engaged with the support leg 3. The connecting member 42 is hinged to the second outer frame 21. The operator turns the lifting screw 41 with a wrench, causing the lifting screw 41 to move the connecting component 42 up and down relative to the support leg 3, so as to make a fine adjustment to the horizontal height of the second bracket 2, so that the top surface of the second bracket 2 is flush with the top surface of the first bracket 1, ensuring a smooth horizontal transition of the entire cooling section and preventing the thick plate from bending.

[0029] In this embodiment, one end of each second cooling roller 22 is supported on the intermediate support beam 212 by an adjusting plate 23. Each adjusting plate 23 has at least one pair of adjusting waist holes 230, which are spaced apart in the front-back direction. Each adjusting waist hole 230 extends in the vertical direction. Each adjusting plate 23 is fixed to the intermediate support beam 212 by bolts passing through the adjusting waist holes 230. The installation height of the second cooling roller 22 on the second outer frame 21 can be adjusted by the vertically extending adjusting waist holes 230, effectively compensating for manufacturing and installation errors.

[0030] like Figure 1 , 5 As shown in Figure 6, the end of the last second bracket 2 is provided with a transition section for smoothly and accurately guiding the thick plate into the traction machine 40. The transition section includes two rows of conveyor rollers 24 mounted on the second outer frame 21 in place of part of the second cooling roller 22, and at least two pairs of nylon wheels 25 perpendicular to the axis of the second cooling roller 22. The conveyor rollers 24 are parallel to the second cooling roller 22, and the diameter of each conveyor roller 24 is the same as the diameter of the first cooling roller 12. The two rows of conveyor rollers 24 are arranged opposite each other from left to right, and each row of conveyor rollers 24 is spaced apart from front to back to support the thick plate flatly. The nylon wheels 25 are arranged in pairs, with multiple pairs of nylon wheels 25 spaced apart from front to back. Each pair of nylon wheels 25 is arranged opposite each other from left to right. When the thick plate is conveyed on the conveyor rollers 24, each pair of nylon wheels 25 restricts the conveying of the thick plate in the left and right direction, so that the thick plate moves between each pair of opposite nylon wheels 25, guides the side of the thick plate, prevents it from deviating, and ensures the stability of the production process.

[0031] In this embodiment, the transition section further includes a plurality of crossbeams 214 mounted on the second outer frame 21. Each crossbeam 214 extends in the left-right direction and connects between the middle support beam 212 and the left support beam 211 or between the middle support beam 212 and the right support beam 213. Each nylon wheel 25 is movably mounted on a crossbeam 214 in the left-right direction. Each nylon wheel 25 moves back and forth along the crossbeam 214 to adjust the distance between each pair of nylon wheels 25, thereby adapting to thick plates of different widths.

[0032] like Figure 1-3As shown, both the first bracket 1 and the second bracket 2 connected to the first bracket 1 are equipped with trimming devices 50, and each trimming device 50 is equipped with a cutting blade 5 for cutting the sheet metal. A flattening device 60 is also installed on the rear side of the trimming device 50 of the first bracket 1. The flattening device 60 has a flattening roller 6 that is vertically opposite to one of the first cooling rollers 12 and a lifting assembly 7 that drives the flattening roller 6 to press the thick sheet metal onto the first cooling roller 12. The lifting assembly 7 is used to adjust the distance between the flattening roller 6 and the corresponding first cooling roller 12, so as to adapt to the flattening of sheet metal of different thicknesses.

[0033] During operation, the three-roll calender 20 calenders the sheet material blank and then conveys it into the thick plate forming machine 30. The thick plate forming machine 30 tempers and shapes the thick plate. After shaping, the thick plate first passes through the first cooling roller 12 of the first support 1 for preliminary cooling. Then, it enters the second support 2 connected in series from front to back, and is stably supported and continuously cooled by the alternately arranged second cooling rollers 22. At the end transition section, the conveying roller 24 and the adjustable nylon wheel 25 work together to ensure that the thick plate is centered and smoothly guided into the traction machine 40.

[0034] The cooling bracket structure of this application is stable and has reasonable support, providing stable and smooth support and transportation for wide and thick plates. It can adapt to the cooling needs and stress states at different stages, effectively prevent the deformation of wide and thick plates during the cooling process, and improve product quality and production stability.

Those skilled in the art should understand that this application is not limited to the above embodiments.
