Description

Technical Field

[0001] This utility model relates to a molding equipment for photovoltaic profiles. Background Technology

[0002] As a key component of photovoltaic (PV) power generation systems, photovoltaic (PV) mounting brackets provide stable support for PV panels and ensure their secure fixation on rooftops. PV mounting brackets are typically used to install PV panels on building roofs or ground surfaces, enabling them to withstand wind, rain, snow, and other external forces under various environmental conditions while maintaining sufficient stability to ensure the long lifespan of the PV panels and high-efficiency power generation.

[0003] In the manufacturing process of photovoltaic mounting panels, the forming of the profile sheet is a crucial step. During manufacturing, the profile sheet passes through multiple forming roller sets along the conveying direction. These forming roller sets typically consist of upper and lower forming rollers. The profile sheet is gradually pressed into the desired shape through the gap between these two rollers. The shape of the gap between the upper and lower forming rollers gradually changes as the conveying direction advances, allowing the profile sheet to be gradually formed, ultimately achieving the required shape and structural characteristics of the photovoltaic mounting panel.

[0004] The side support structure of photovoltaic panels is typically presented in the form of protrusions or recesses, but traditional side support structures are relatively simple in shape design. Common protruding or recessed side support structures are usually straight or curved designs, with little consideration given to applications of other complex shapes. With simple structures, they are prone to detachment when engaging with the fixed structure on the roof. Utility Model Content

The recessed depth of the first forming gap of the multiple forming roller groups in the recessed area gradually decreases along the conveying direction.

[0012] The Z-shaped bending area is provided with multiple sets of rollers at intervals along the conveying direction. The two roller structures of each set of rollers correspond to the two sides of the flat and concave portion. The second forming gap in the Z-shaped bending area is Z-shaped. The profile plate passes through multiple sets of rollers in sequence to form a first Z-shaped step on both sides of the flat and concave portion.

[0013] The deepening zone is provided with a plurality of forming roller groups at intervals along the conveying direction. The depth of the first forming gap of the plurality of forming roller groups in the deepening zone gradually increases along the conveying direction. The profile plate passes through the plurality of forming roller groups in the concave zone in sequence along the conveying direction so that the flat and concave parts are gradually deepened.

[0014] In a preferred embodiment, the recessed area is provided with at least four forming roller groups; wherein the forming roller groups located upstream and downstream in the conveying direction are transversely mounted on the frame and connected to the drive mechanism; one end of the forming roller group located midway in the conveying direction is rotatably disposed on the right side of the frame.

[0015] In a preferred embodiment, the Z-shaped bending area is provided with at least two of the roller assemblies; the Z-shaped bending area further includes a forming roller assembly disposed on the two roller assemblies, the forming roller assembly being laterally mounted on the frame and connected to the drive mechanism.

[0016] In a preferred embodiment, a set of guide rollers is provided between two adjacent forming roller sets in the deepening zone.

[0017] In a preferred embodiment, the roller assembly further includes an upper support frame and a lower support frame connected to the frame. The upper support frame and the lower support frame are respectively provided with adjustment grooves, which extend along the lateral direction of the frame. The upper forming roller is adjustablely positioned on the adjustment groove of the upper support frame, and the lower forming roller is adjustablely positioned on the adjustment groove of the lower support frame, so as to adjust the width and position of the corresponding second forming gap.

[0018] In a preferred embodiment, the upper forming roller further includes an upper roller seat and an upper roller body, the upper roller body being rotatably mounted on the upper roller seat, and the upper roller seat being connected to the upper support frame by a first bolt passing through the adjustment groove;

[0019] The lower forming roller also includes a lower roller seat and a lower roller body. The lower roller body is rotatably mounted on the lower roller seat. The lower roller seat is connected to the lower support frame by a second bolt, and the first bolt passes through the adjustment groove.

[0020] In a preferred embodiment, the upper rotating wheel seat is provided with a plurality of the adjustment slots, and the lower rotating wheel seat is provided with a plurality of the adjustment slots.

[0021] In a preferred embodiment, the guide roller assembly includes two upper forming rollers and two lower forming rollers, with the two upper forming rollers and the two lower forming rollers respectively forming two guide roller structures vertically and vertically, and the two guide roller structures are spaced apart along the conveying direction.

[0022] In a preferred embodiment, the upper rotating wheel body is rotatably mounted on the upper rotating wheel seat via a bearing, and the lower rotating wheel body is rotatably mounted on the lower rotating wheel seat via a bearing.

[0023] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0024] This forming equipment, by setting recessed areas, Z-shaped bending areas, and deepening areas, can form photovoltaic bracket side support structures with complex structures on profile plates.

[0025] In the recessed area, multiple forming rollers progressively press the profile sheet, with the recess depth gradually decreasing along the conveying direction, gradually forming a flat-recessed area on the profile sheet surface. This design helps avoid stress concentration in the material caused by one-time forming, improving processing accuracy and finished product quality. Especially during the transitional forming process in the flat-recessed area, the material is subjected to more uniform stress, reducing the possibility of breakage or deformation. In the Z-bending area, multiple roller sets bend the flat-recessed area of ​​the profile sheet on both sides, gradually forming the first Z-shaped step. In the deepening area, through further multi-stage pressure roller action, the flat-recessed area gradually deepens, ultimately forming a recessed structure with considerable depth. Because the multiple forming roller sets and roller sets of the forming equipment are arranged sequentially along the conveying direction, the profile sheet can gradually complete the forming of complex structures during continuous conveying. This continuous forming process is more efficient than traditional single-step bending or pressing processes. Simultaneously, the progressive adjustment design of multiple forming areas ensures the forming accuracy of each area, significantly improving the shape consistency and dimensional accuracy of the final product, reducing the defect rate and the need for subsequent adjustment processing.

[0026] The roller assembly also includes an upper support frame and a lower support frame connected to the machine frame. Each of the upper and lower support frames is provided with an adjustment groove extending laterally along the machine frame. The upper forming roller and the lower forming roller are adjustablely positioned on the adjustment grooves of the upper and lower support frames, allowing adjustment of the width and position of the corresponding second forming gap. The adjustment grooves on the upper and lower support frames enable flexible adjustment of the positions of the upper and lower forming rollers. By adjusting the position of the rollers along the adjustment grooves, the width and position of the forming gap can be changed. This solves the problem of fixed positions in traditional roller assemblies, which cannot adapt to different profile plate requirements, significantly improving the adaptability and flexibility of the equipment. Because the position of the rollers can be easily adjusted via the adjustment grooves, the equipment does not need to replace components when producing different models or specifications of profile plates. The adjustment process is simpler and faster, effectively shortening the equipment debugging time and improving production efficiency. Attached Figure Description

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] See Figures 1-7 A photovoltaic profile forming device includes a frame 1 and a plurality of forming roller groups 2 and a plurality of roller groups 3 arranged on the frame 1; the plurality of forming roller groups 2 and the plurality of roller groups 3 are arranged at intervals along a conveying direction;

[0036] The forming roller group 2 includes an upper forming roller 21 and a lower forming roller 22 that rotate in opposite directions, and the guide roller group 3 includes an upper forming roller 31 and a lower forming roller 32 that rotate in opposite directions. In this embodiment, multiple forming roller groups 2 are spaced apart along the conveying direction, and multiple guide roller groups 3 are spaced apart along the conveying direction. The guide roller groups 3 can be arranged continuously or interspersed between two forming roller groups 2. In this embodiment, multiple forming roller groups 2 are synchronously driven by a drive mechanism to achieve synchronous rotation of multiple forming roller groups 2. In this embodiment, the upper forming roller 21 and the lower forming roller 22 of each forming roller group 2 are meshed by gears to achieve opposite rotation, and adjacent upper forming rollers 21 are connected by belts or chains. Therefore, the forming roller group 2 is an active conveying device, and the guide roller group 3 is a driven conveying device. A profile plate moves along the conveying direction by being driven by multiple forming roller groups 2.

[0037] A first forming gap 23 is formed between the upper forming roller 21 and the lower forming roller 22, and a second forming gap 33 is formed between the upper forming roller 31 and the lower forming roller 32. The side of the profile plate passes through multiple first forming gaps 23 and multiple second forming gaps 33 along the conveying direction to form a side support structure.

[0038] The forming equipment includes a recessed area 4, a Z-shaped bending area 5, and a deepening area 6 distributed sequentially along the conveying direction; the recessed area 4 is provided with multiple forming roller groups 2 spaced apart along the conveying direction, and the profile plate passes sequentially through multiple forming roller groups 2 in the recessed area 4 along the conveying direction to gradually form a flat concave portion 41, and the concavity depth of the first forming gap 23 of the multiple forming roller groups 2 in the recessed area 4 gradually decreases along the conveying direction; the Z-shaped bending area 5 is provided with multiple guide roller groups 3 spaced apart along the conveying direction, and the guide roller group 3 has two guide roller structures 37 Corresponding to both sides of the concave-convex portion 41, the second forming gap 33 in the Z-shaped bending area 5 is Z-shaped. The profile plate passes through multiple sets of rollers 3 in sequence to form a first Z-shaped step 51 on both sides of the concave-convex portion 41. The deepening area 6 is provided with multiple forming roller sets 2 at intervals along the conveying direction. The depth of the first forming gap 23 of the multiple forming roller sets 2 in the deepening area 6 gradually increases along the conveying direction. The profile plate passes through multiple forming roller sets 2 in the concave area 4 in sequence along the conveying direction to gradually deepen the concave-convex portion 41.

[0039] The recessed area 4 is equipped with at least four forming roller groups 2. The forming roller groups 2 located upstream and downstream in the conveying direction are horizontally mounted on the frame 1 and connected to the drive mechanism. One end of the forming roller group 2 located midway in the conveying direction is rotatably mounted on the right side of the frame 1. The presence of at least four forming roller groups 2 in the recessed area 4 ensures sufficient force distribution on the profile sheet during the initial forming stage, gradually forming the recessed structure. By setting forming roller groups 2 upstream and downstream in the conveying direction and connecting them to the drive mechanism, stable conveying and consistent force distribution of the sheet material during the forming process are guaranteed, preventing displacement or deformation of the sheet material. Simultaneously, the fact that one end of the forming roller group 2 located midway in the conveying direction is positioned on the right side of the frame provides a flexible installation method, facilitating fine-tuning according to the specific shape of the sheet material or processing requirements, further improving the forming accuracy and stability.

[0040] The Z-shaped bending zone 5 is equipped with at least two roller sets 3. The Z-shaped bending zone 5 also includes a forming roller set 2 positioned between the two roller sets 3. This forming roller set 2 is horizontally mounted on the frame 1 and connected to the drive mechanism. Through the coordinated use of at least two roller sets 3, the Z-shaped bending zone 5 can precisely control the bending angle of the profile sheet and the formation of the Z-shaped step, resulting in a Z-shaped structure with high strength and consistency. The Z-shaped bending zone 5 also includes a forming roller set 2, which is connected to the drive mechanism, further stabilizing the transmission speed and force of the profile sheet during the bending process. This ensures uniform forming of the Z-shaped structure and avoids errors generated during bending. This arrangement not only ensures the precise forming of the Z-shaped step but also improves the efficiency and reliability of the forming process.

[0041] A guide roller group 3 is provided between two adjacent forming roller groups 2 in the deepening zone 6. In the deepening zone 6, as the forming roller group 2 gradually increases the concavity depth of the profile plate, the guide roller group 3 can effectively maintain the shape of the Z-shaped step already formed in the Z-shaped bending zone. Because the profile plate is subjected to complex forces during the deepening process, the forming roller group alone may not be able to accurately control the angle and shape of certain bending points. However, the guide roller group 3, by applying appropriate lateral pressure to the profile plate, can assist in completing the forming of these complex bending points, making the final forming result more accurate and stable.

[0042] The roller assembly 3 further includes an upper support frame 34 and a lower support frame 35 connecting the frame 1. The upper support frame 34 and lower support frame 35 are each provided with an adjustment groove 36, which extends along the transverse direction of the frame 1. The upper forming roller 31 is adjustablely positioned on the adjustment groove 36 of the upper support frame 34, and the lower forming roller 32 is adjustablely positioned on the adjustment groove 36 of the lower support frame 35, allowing adjustment of the width and position of the corresponding second forming gap 33. The adjustment grooves 36 on the upper support frame 34 and lower support frame 35 allow for flexible adjustment of the positions of the upper forming roller 31 and lower forming roller 32. By adjusting the position of the rollers along the adjustment grooves 36, the width and position of the forming gap can be changed. This solves the problem of the traditional roller assembly 3 having a fixed position and being unable to adapt to different profile plate requirements, significantly improving the adaptability and flexibility of the equipment. Since the position of the rotating wheel can be easily adjusted through the adjustment slot 36, the equipment does not need to replace components when producing profiles of different models or specifications. The adjustment process is simpler and faster, effectively shortening the equipment debugging time and improving production efficiency.

[0043] The design of the adjustment groove 36 allows for flexible adjustment of the width and position of the forming gap, enabling the equipment to adapt to the forming requirements of different materials. Whether the material is hard or soft, appropriate pressing force can be achieved by adjusting the forming gap, thereby improving the forming effect.

[0044] In this embodiment, the upper forming roller 31 further includes an upper roller seat 311 and an upper roller body 312. The upper roller body 312 is rotatably mounted on the upper roller seat 311. The upper roller seat 311 is connected to the upper support frame 34 by a first bolt 313, which passes through the adjustment groove 36. The lower forming roller 32 further includes a lower roller seat 321 and a lower roller body 322. The lower roller body 322 is rotatably mounted on the lower roller seat 321. The lower roller seat 321 is connected to the lower support frame 35 by a second bolt 323, which passes through the adjustment groove 36. The upper forming roller 31 and the lower forming roller 32 are respectively connected to the upper and lower support frames 35 by bolts, and the bolts pass through the adjustment groove 36. During adjustment, simply loosening the bolts slightly will release the upper roller seat 311 from the fixed state with the upper support frame 34, allowing the upper roller seat 311 to move freely within the adjustment groove 36. Similarly, the lower forming roller 32 can also be adjusted using the same operating method.

[0045] The upper rotating wheel seat 311 and the lower rotating wheel seat 321 are respectively provided with multiple adjustment slots 36. Both the upper and lower rotating wheel seats 311 and 321 are connected to the support frame through multiple adjustment slots 36. Compared to a design relying on only a single adjustment slot 36, multiple adjustment slots 36 provide more support points and fixed positions for the rotating wheel seats. This design effectively disperses the stress generated during adjustment, reducing structural deformation or loosening caused by single-point stress, thus making the rotating wheel seats more stable and reliable during operation. When adjusting the wheel position, the more even distribution of force points results in smoother movement and sliding of the rotating wheel seats, thus avoiding potential shaking or jamming during adjustment.

[0046] The roller assembly 3 includes two upper forming rollers 31 and two lower forming rollers 32. The two upper forming rollers 31 and two lower forming rollers 32 respectively form two roller structures 37, which are spaced apart along the conveying direction. By setting the two roller structures 37, the upper and lower forming rollers 32 can perform multiple progressive forming processes on the profile sheet at different forming stages. Compared to a single-stage forming design, multiple forming allows the profile sheet to receive appropriate pressure at each stage, avoiding deformation or damage caused by excessive pressure at once. Especially for profile sheets with greater thickness or harder materials, this multiple forming method effectively ensures the uniformity and precision of the forming effect.

[0047] In this embodiment, the upper rotating wheel body 312 is rotatably mounted on the upper rotating wheel seat 311 via a bearing, and the lower rotating wheel body 322 is rotatably mounted on the lower rotating wheel seat 321 via a bearing.

[0048] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
