Description

Technical Field

[0001] This utility model relates to the field of aluminum surface processing technology, and in particular to a device for embossing textures on the surface of aluminum alloy doors and windows. Background Technology

[0002] Aluminum alloy doors and windows are widely used in the construction industry due to their aesthetic appeal, durability, and excellent sealing performance. To enhance the decorative effect and added value of aluminum alloy doors and windows, manufacturers often emboss various wood grain, stone grain, and other decorative textures on their surface. Currently, the most common methods for texturing the surface of aluminum alloy door and window profiles are roll forming or coating. Roll forming typically involves continuously rolling the profile with a pair of embossed rollers engraved with corresponding textures. This method is highly efficient and suitable for mass production. However, during the embossing process, the oxide layer on the surface of the aluminum material may break due to embossing and produce debris, which may then stick to the embossing roller. The presence of debris, dust in the workshop, and uncleaned stains on the surface of the aluminum material will all lead to a decrease in the clarity of the embossed texture and a reduction in the surface texture. Furthermore, debris and dust may damage the embossing roller, resulting in further economic losses.

[0003] Therefore, a surface texture embossing device for aluminum alloy doors and windows with cleaning function is of positive significance. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide an aluminum alloy door and window surface texture embossing device.

[0005] This utility model provides an aluminum alloy door and window surface texture embossing device, comprising: An embossing mechanism, comprising an active roller and a driven roller for embossing textures on aluminum; A conveying mechanism, located on the right side of the stamping mechanism, includes a conveyor belt for conveying the aluminum material; The cleaning mechanism includes a suction hood positioned above the drive roller. The top of the suction hood is connected to several suction pipes extending towards the side closer to the conveyor belt. A first cleaning section, rotatable and with its axis vertical, is located on the side of the suction pipes away from the suction hood. This first cleaning section is used to clean stains on the aluminum material. The cleaning mechanism also includes a second cleaning section positioned on the side of the drive roller closer to the conveyor belt and slidable in a forward-backward direction. This second cleaning section is used to clean debris adhering to the drive roller. A suction fan is installed inside the suction pipes. The suction fan guides airflow, debris, and dust from the drive roller into the suction hood, causing the airflow to exit from the end of the suction pipes away from the suction hood, and driving the first cleaning section to rotate.

[0006] According to the technical solution provided in the embodiments of this application, a filter plate for filtering debris and dust is provided in the suction duct and between the suction fan and the suction hood, and a scale storage tank for storing debris and dust is provided in the suction duct and between the filter plate and the suction hood.

[0007] According to the technical solution provided in the embodiments of this application, the first cleaning unit includes: A first rotating shaft that can rotate on its own is located on the side of the air intake duct away from the air intake hood, and its axis is in the vertical direction. Several first fan blades are arranged circumferentially on the top of the first rotating shaft, and their positions correspond to the end of the air intake pipe away from the air intake hood. The first cleaning component is located at the bottom end of the first rotating shaft and is used to clean stains on the aluminum material.

[0008] According to the technical solution provided in the embodiments of this application, the second cleaning part includes a second mounting plate disposed on the side of the drive roller near the conveyor belt. The top surface of the second mounting plate is connected to the bottom surface of the suction hood. A first mounting plate, which is an inverted L-shaped plate, is connected to the bottom surface of the second mounting plate. A second cleaning member that can slide in the front-back direction is provided on the top surface of the horizontal portion of the first mounting plate. A rack is provided on the end of the second cleaning member away from the drive roller. A gear is meshed with the side of the rack away from the drive roller. The second cleaning part also includes a second drive motor, which is used to drive the gear to rotate, thereby driving the rack and the second cleaning member to slide in the front-back direction.

[0009] According to the technical solution provided in the embodiments of this application, protective supports are provided at both ends of the conveyor belt, and the cleaning mechanism further includes a third cleaning part disposed on the protective supports and used to clean stains on the aluminum material.

[0010] According to the technical solution provided in the embodiments of this application, the third cleaning part includes a U-shaped plate disposed on the top surface of the protective bracket, and a third cleaning component is connected to the bottom surface of the horizontal part of the U-shaped plate. The third cleaning component is used to clean the stains on the aluminum material.

[0011] According to the technical solution provided in the embodiments of this application, the imprinting mechanism further includes an imprinting bracket for mounting the active roller and the driven roller; the imprinting mechanism further includes a first drive motor for driving the active roller to rotate.

[0012] According to the technical solution provided in the embodiments of this application, the active roller includes an imprinting shaft, and a set of armor pieces for imprinting textures are fitted on the imprinting shaft; the two ends of the imprinting shaft near the imprinting bracket are connecting ends, and the connecting ends are fitted with locking pieces for positioning the armor pieces; the front and rear ends of the active roller are also provided with a number of screws, which pass through the armor pieces and are threadedly connected to the front and rear ends of the imprinting shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are: The cleaning mechanism of this invention places the suction hood directly above the point where the stamping action occurs (the active roller), which can suck up debris the instant it is generated, while also removing dust. This effectively prevents dust and debris from adhering to the side surface of the active roller during the stamping process, thus avoiding any impact on the clarity and surface texture of the aluminum material. It also prevents dust and debris from spreading into the workshop air, optimizing the working environment and protecting worker health. The airflow exhausted through the suction duct is used as the power source to drive the rotation of the first cleaning section, eliminating the need for a separate motor for the first cleaning section, simplifying the structure, and reducing energy consumption and equipment costs. Before the aluminum material enters the stamping mechanism, the first cleaning section can effectively clean it. In addition to removing dust, oil, and other impurities from the aluminum surface, the first cleaning unit can automatically start cleaning when the suction fan starts (i.e., when the embossing begins), requiring no additional control, resulting in a high degree of automation and reliability. During the embossing process, debris inevitably adheres to the active roller. The continuous sliding cleaning by the second cleaning unit prevents debris from accumulating in the mold texture, avoiding embossing defects caused by unclean molds (such as blurred textures, scratches on the aluminum material, etc.). At the same time, the cleaned debris is quickly sucked away by the negative pressure airflow generated by the suction fan, forming a closed loop of "cleaning-collection" to prevent secondary pollution and ensure the cleaning effect.

[0014] The active roller of this invention allows for changes in embossed patterns or designs without replacing the entire bulky and expensive active roller. Simply remove the old armor assembly and replace it with the new one. This greatly shortens mold change time and makes small-batch, multi-variety customized production economical and feasible.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0019] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Please refer to Figures 1-5 An embodiment of this utility model provides an aluminum alloy door and window surface texture embossing device, comprising: The embossing mechanism 1 includes an active roller 12 and a driven roller 13 for embossing textures on the aluminum material 3; The conveying mechanism 4 is located on the right side of the stamping mechanism 1 and includes a conveyor belt 41 for conveying aluminum material 3. The cleaning mechanism 2 includes a suction hood 21 located above the drive roller 12. The top of the suction hood 21 is connected to several suction pipes 22 extending toward the side closer to the conveyor belt 41. The suction pipes 22 away from the suction hood 21 are provided with a first cleaning part 26 that can rotate, with its axis in the vertical direction. The first cleaning part 26 is used to clean stains on the aluminum material 3. The cleaning mechanism 2 also includes a second cleaning part 27 located on the side of the drive roller 12 near the conveyor belt 41 and that can slide in the front-back direction. The second cleaning part 27 is used to sweep away debris stuck on the drive roller 12. A suction fan 25 is provided inside the suction pipe 22. The suction fan 25 is used to guide the airflow, debris and dust at the drive roller 12 into the suction hood 21, so that the airflow is discharged from the end of the suction pipe 22 away from the suction hood 21, and the airflow drives the first cleaning part 26 to rotate.

[0021] When the imprinting mechanism 1 starts imprinting the texture, it drives the suction fan 25. The suction fan 25 has strong suction power and guides the airflow, debris and dust at the active roller 12 into the suction hood 21, so that the airflow is discharged from the end of the suction pipe 22 away from the suction hood 21. The discharged airflow drives the first cleaning part 26 to rotate. The first cleaning part 26 starts to clean the stains on the surface of the aluminum material 3 that needs to be imprinted. At the same time, the second cleaning part 27 starts to slide in the front and back direction to clean the debris stuck on the active roller 12. The debris enters the suction hood 21 with the airflow.

[0022] In this embodiment, the side surface of the active roller 12 is provided with an imprinting texture, while the side surface of the driven roller 13 is smooth, ensuring smooth imprinting of the aluminum material 3. The conveyor belt 41 transports the aluminum material 3, reducing manual transportation and helping to improve the overall production efficiency of the device. The cleaning mechanism 2 places the suction hood 21 directly above the point where the imprinting action occurs (active roller 12), which can suck away debris instantly when it is generated, while also sucking away dust. This effectively prevents the side surface of the active roller 12 from being affected by dust and debris during the imprinting process, thus affecting the clarity and surface texture of the aluminum material 3. It also prevents dust and debris from spreading into the workshop air, optimizing the working environment and protecting the health of workers. The strong suction generated by the suction fan 25 not only completes the main dust collection task, but the airflow discharged through the suction pipe 22 is used as the power source to drive the rotation of the first cleaning section 26, which eliminates the need for a separate electric motor for the first cleaning section 26. The machine simplifies the structure and reduces energy consumption and equipment costs. Before the aluminum material 3 enters the imprinting mechanism 1, the first cleaning section 26 can effectively remove dust, oil and other impurities from the surface of the aluminum material 3, directly improving the product yield and appearance quality. Moreover, the first cleaning section 26, which uses the airflow discharged from the suction pipe 22 as a power source, can automatically start cleaning when the suction fan 25 is started (i.e., imprinting begins), without the need for additional control. It has a high degree of automation and good reliability. During the imprinting process, debris inevitably adheres to the active roller 12. The continuous sliding cleaning by the second cleaning section 27 can prevent debris from accumulating in the mold texture, avoiding imprinting defects (such as blurred texture, scratches on the aluminum material 3, etc.) caused by unclean molds. At the same time, the debris is quickly sucked away by the negative pressure airflow generated by the suction fan 25, forming a "cleaning-collection" closed loop, preventing secondary pollution and ensuring the cleaning effect.

[0023] This device integrates three functions—"aluminum material pretreatment (cleaning)," "mold maintenance (scraping)," and "waste collection (vacuuming)"—into a compact system, seamlessly connecting with the embossing process to achieve process integration. Simultaneously, using the suction fan 25 as the main power source, it drives both vacuuming and rotary cleaning functions, demonstrating excellent energy efficiency. Furthermore, the entire cleaning process is linked to the embossing action, enabling uninterrupted automatic cleaning and maintenance during production, reducing reliance on manual intervention and facilitating stable and continuous production of high-quality products.

[0024] In some embodiments, a filter plate 24 for filtering debris and dust is provided inside the suction duct 22 and between the suction fan 25 and the suction hood 21, and a dirt storage tank 23 for storing debris and dust is provided inside the suction duct 22 and between the filter plate 24 and the suction hood 21.

[0025] like Figure 2As shown, the filter plate 24 intercepts solid particles in the airflow containing debris and dust before it reaches the suction fan 25. This effectively prevents the impeller of the suction fan 25 from being entangled or jammed by debris, avoiding overload, damage, or reduced efficiency of the suction fan 25 due to blockage, greatly improving the reliability and service life of the suction fan 25. Furthermore, the airflow flowing to the suction fan 25 and ultimately discharged after filtration by the filter plate 24 becomes relatively clean. This prevents rough, sharp debris from impacting the first cleaning section 26 with the high-speed airflow, reducing wear and potential damage to this component and ensuring the long-term stable operation of the first cleaning section 26. The scale storage tank 23 provides a temporary storage point for the filtered contaminants. It concentrates debris and dust in one place, rather than scattering randomly on the inner wall of the pipe or accumulating on the side of the filter plate 24 near the contaminant source. This design greatly facilitates subsequent cleaning and maintenance.

[0026] In some embodiments, the first cleaning unit 26 includes: The first rotating shaft 261, which can rotate on its own, is located on the side of the suction duct 22 away from the suction hood 21, and its axis is in the vertical direction. Several first fan blades 262 are arranged circumferentially on the top of the first rotating shaft 261, and their positions correspond to the end of the suction duct 22 away from the suction hood 21. The first cleaning component 263 is located at the bottom of the first rotating shaft 261 and is used to clean stains on the aluminum material 3.

[0027] like Figure 1 and Figure 2 As shown, the first fan blade 262 faces the outlet of the suction duct 22, maximizing the capture of the kinetic energy of the high-speed airflow discharged from the suction duct 22. This results in high conversion efficiency and eliminates the need for a separate motor or transmission system for the first cleaning component 263. This significantly simplifies the structure, reduces manufacturing costs and energy consumption, and achieves true "zero additional energy consumption" cleaning. The first rotating shaft 261 effectively transmits the wind energy (rotational power) received by the top first fan blade 262 to the bottom first cleaning component 263. Its vertical axis design ensures a direct and efficient power transmission path with minimal energy loss. The first cleaning component 263 can be a cleaning sponge, allowing direct contact with the surface of the aluminum material 3. Through rotating brushing motion, it effectively removes dust, oil, and other impurities from the surface of the aluminum material 3. A clean aluminum surface is crucial for ensuring clear and flawless embossing textures, directly improving product yield. The first cleaning unit 26 and the suction fan 25 operate in complete synchronization. As soon as the suction fan 25 starts (embossing begins), the first cleaning unit 263 automatically rotates; when embossing stops, the first cleaning unit 263 also stops. This achieves complete automation, requiring no additional switches or control circuits, resulting in extremely high reliability.

[0028] In some embodiments, the second cleaning section 27 includes a second mounting plate 272 disposed on the side of the drive roller 12 near the conveyor belt 41. The top surface of the second mounting plate 272 is connected to the bottom surface of the suction hood 21. The bottom surface of the second mounting plate 272 is connected to a first mounting plate 271, which is an inverted L-shaped plate. The top surface of the horizontal portion of the first mounting plate 271 is provided with a second cleaning member 273 that can slide in the front-back direction. The end of the second cleaning member 273 away from the drive roller 12 is provided with a rack 274. The rack 274 is meshed with a gear 275 on the side away from the drive roller 12. The second cleaning section 27 also includes a second drive motor 276, which is used to drive the gear 275 to rotate, thereby driving the rack 274 and the second cleaning member 273 to slide in the front-back direction.

[0029] Furthermore, the horizontal portion of the first mounting plate 271 has a protrusion on its horizontal surface, and the second cleaning component 273 has a sliding groove that matches the protrusion.

[0030] Furthermore, a second rotating shaft 277 is provided in the middle of the gear 275, and the top end of the second rotating shaft 277 is driven and connected to the output end of the second drive motor 276.

[0031] like Figures 1-3 As shown, the first mounting plate 271 and the second mounting plate 272 form a robust cantilever frame, stably suspending the entire second cleaning part 27 directly above the drive roller 12. This ensures that the cleaning part will not shake or shift during operation, and its positioning is accurate. The sliding groove of the second cleaning part 273 cooperates with the protrusion of the first mounting plate 271, which can effectively limit the sliding trajectory of the second cleaning part 273 and prevent deviation. The second cleaning part 273 can be selected as a brush, which can effectively scrape or sweep away aluminum chips and impurities embedded in the roller texture, prevent imprinting defects, ensure product quality, and through reciprocating sliding in the front and back directions, the second cleaning part 273 can clean the entire axial width of the drive roller 12 without dead angles, ensuring the cleanliness of every part of the roller surface and avoiding the problem of incomplete cleaning in some areas. The rack 274 and gear 275 The second rotating shaft 277 cooperates with the second drive motor 276 to accurately and efficiently convert the rotational motion of the second drive motor 276 into smooth linear motion. This transmission method has good rigidity and small backlash, which can ensure that the second cleaning component 273 slides stably along the predetermined trajectory. Moreover, compared with belt and chain transmission methods, the rack and pinion 274 and gear 275 transmit power directly and have strong load-bearing capacity, which can provide sufficient thrust to ensure that the second cleaning component 273 effectively scrapes off firmly adhered debris.

[0032] In some embodiments, protective supports 42 are provided at both ends of the conveyor belt 41, and the cleaning mechanism 2 further includes a third cleaning part 28 provided on the protective supports 42 for cleaning stains on the aluminum material 3.

[0033] like Figure 1 , Figure 2 and Figure 4 As shown, the protective bracket 42 prevents the aluminum material 3 from slipping off the side of the conveyor belt 41 during transmission due to offset or other unexpected reasons, avoiding workpiece drop, deformation, and potential personal injury, thus improving the safety of the production line. It also provides an ideal and readily available support structure for installing the third cleaning unit 28. This allows the third cleaning unit 28 to be precisely positioned at the location requiring cleaning (above or to the side of the aluminum material 3) without the need for a separate, complex mounting frame, simplifying the structure and saving cost and space. The third cleaning unit 28 complements and enhances the function of the first cleaning unit 26, improving the overall cleaning effect on the surface of the aluminum material 3 and further ensuring the cleanliness of the finished product.

[0034] In some embodiments, the third cleaning part 28 includes a U-shaped plate 281 disposed on the top surface of the protective bracket 42, and a third cleaning member 282 is connected to the bottom surface of the horizontal portion of the U-shaped plate 281. The third cleaning member 282 is used to clean stains on the aluminum material 3.

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, the U-shaped plate 281 spans above the conveyor belt 41 and the aluminum material 3. It uses the legs on both sides and the crossbeam on the top to form a very stable and rigid support frame, which can effectively resist vibration and ensure that the third cleaning component 282 installed on it works smoothly. The third cleaning component 282 can be selected as a brush, roller brush, air knife or air nozzle, etc., which can further clean the imprinted surface of the aluminum material 3 and further improve the overall cleaning effect of the surface of the aluminum material 3.

[0036] In some embodiments, the embossing mechanism 1 further includes an embossing bracket 11 for mounting the drive roller 12 and the driven roller 13; the embossing mechanism 1 also includes a first drive motor 14 for driving the drive roller 12 to rotate.

[0037] Furthermore, one end of the drive roller 12 is driven and connected to the output end of the first drive motor 14.

[0038] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the embossing bracket 11 provides a robust, stable, and non-deformable mounting platform for the driving roller 12 and the driven roller 13, which ensures the parallelism and relative position accuracy of the two roller axes, which is the basis for ensuring uniform and consistent embossing texture. The first drive motor 14 can precisely control the feed speed of the aluminum material 3, ensuring that a continuous and uniform embossing texture can be obtained. The first drive motor 14 directly drives the driving roller 12, which has a short power transmission path, high efficiency, and fast response speed. This design avoids complex transmission chains, has a simple structure, and high reliability.

[0039] In some embodiments, the active roller 12 includes an impression shaft 121, and an armor piece 125 for impressioning texture is fitted over the impression shaft 121; the two ends of the impression shaft 121 near the impression bracket 11 are connection ends 122, and the connection ends 122 are fitted over the locking pieces 124 for positioning the armor pieces 125; the active roller 12 is also provided with a plurality of screws 126 at the front and rear ends, the screws 126 passing through the armor pieces 125 and threadedly connected to the front and rear ends of the impression shaft 121.

[0040] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the impression shaft 121 serves as the "skeleton" of the drive roller 12, providing sufficient strength and rigidity to withstand impression pressure and torque. The connecting ends 122 at both ends are connected to the first drive motor 14 and the imprinting bracket 11, ensuring efficient and stable power input. When it is necessary to change the imprinted pattern or design, it is not necessary to replace the entire bulky and expensive drive roller 12. Simply remove the old armor parts 125 and replace them with new ones. This greatly shortens the mold change time and makes small-batch, multi-variety customized production economical and feasible. The main function of the locking part 124 is to determine the accurate axial position of all armor parts 125 on the rotating shaft and prevent them from axially moving during the imprinting process, ensuring the continuity and consistency of the imprinted texture. The locking force provided by the screw 126 firmly fixes the armor parts 125 on the imprinting rotating shaft 121, preventing relative rotation (slippage) or loosening between them and the rotating shaft during high-speed rotation and imprinting, ensuring the reliability of power transmission. Furthermore, the use of screw 126 means that assembly and disassembly are very convenient. Mold change operations can be completed using only a common tool (wrench), further demonstrating the convenience of modular design.

[0041] Optionally, a ring electromagnet 123 is provided between the connecting end 122 and the locking member 124.

[0042] When the armor piece 125 is made of magnetic material, the ring electromagnet 123 can assist in positioning the armor piece 125 and speed up the installation process, which is beneficial to improving the production efficiency of this device.

[0043] In some embodiments, a connecting column 29 for fixing the suction hood 21 is connected to the suction hood 21, and the connecting column 29 is connected to the workshop roof; a first connecting plate 264 is rotatably connected to the top of the first rotating shaft 261, and the top surface of the first connecting plate 264 is connected to the workshop roof.

[0044] like Figure 1 and Figure 2As shown, the connecting column 29 and the first connecting plate 264 suspend the bulky and large suction hood 21 on the workshop roof, so that it does not compete with the ground equipment for space. This keeps the ground around the equipment clean and unobstructed, which is convenient for operators to walk, maintain and transport materials. It is especially suitable for workshops with compact space. Moreover, the structure of the workshop roof is usually very strong. Using this as a fixed point, it can provide an extremely stable and unshakable support for the suction hood 21 and the entire airflow system connected to it, ensuring the accuracy of the position of the suction hood 21 and the reliability of long-term operation.
