Abstract
Description
Technical Field
[0001] This application relates to the field of door and wall cabinet processing technology, and in particular to a multi-functional radio frequency vacuum integrated machine for door and wall cabinet processing. Background Technology
[0002] Radio frequency (RF) heating is a technology that uses electromagnetic waves with frequencies between 3kHz and 300MHz to heat materials. This heating method has many advantages: RF heating is very fast; the high-frequency alternating electromagnetic waves can rapidly cause the molecules in the material to move at high speeds, achieving a rapid heating effect. This heating method also features uniform heating from both inside and out, ensuring that the material is heated evenly and avoiding localized overheating or underheating.
[0003] Currently, with the increasing popularity of customized furniture, various specially shaped furniture pieces have emerged. Among them, the processing of door and wall cabinets requires pressing or bending wooden boards into curved boards or corners with a certain arc or angle. The traditional processing method is to use a hot press to heat and soften the wooden boards with steam or hot air, making its internal fiber structure softer and easier to cure and shape later. However, the hot press has a single function, and the processing method using a hot press is not only inefficient, but also results in uneven temperature distribution inside and outside the wooden board after heating. The hot pressing process is greatly affected by the external temperature and is costly. Summary of the Invention
[0004] In order to improve the processing efficiency and quality of irregularly shaped door and wall cabinets, this application provides a multi-functional radio frequency vacuum integrated machine for door and wall cabinet processing.
[0005] The multi-functional radio frequency vacuum integrated machine for door and wall cabinet processing provided in this application adopts the following technical solution:
[0006] Multifunctional RF vacuum integrated machine for door and wall cabinet processing, including
[0007] frame;
[0008] A molding device is provided on the frame and there are multiple molding devices. The molding device includes a molding chamber, a support platform fixed in the molding chamber, a mold provided above the support platform, a cover provided on the top of the molding chamber, and multiple radio frequency heaters provided on the cover.
[0009] The frame is provided with a molding area and a shaping area. The shaping area contains multiple shaping chambers, which are spaced apart along the height of the frame. Each shaping chamber corresponds to one of the molding devices, with one molding device located in the molding area and the remaining molding devices located within the shaping chambers. The system also includes:
[0010] A molding device includes a molding mechanism, a setting mechanism, and a shifting mechanism. The molding mechanism is disposed between the molding chamber and the molding area, and is used to mold the profile in the molding chamber into a shape adapted to the mold under vacuum conditions through the mold. The setting mechanism is disposed between the molding chamber and the setting area, and is used to hold and set the molded profile in the molding chamber under pressure. The shifting mechanism is disposed between the molding area and the setting area, and is used to move and interchange the molding device in the molding area and the setting area.
[0011] By adopting the above technical solution, when processing the profile, the profile to be processed is first placed above the mold on the support platform of the molding device in the molding zone. Then, the cover is closed to form a closed molding chamber. The radio frequency heater starts working, rapidly and evenly heating the profile to soften the internal fiber structure. Simultaneously with the radio frequency heating, the molding mechanism is activated to evacuate the inside of the molding chamber, gradually bringing the profile closer to the mold. Under vacuum, the profile is shaped by the mold to form a shape that matches the mold. Subsequently, the transfer mechanism is activated to move the shaped profile from the molding zone to the setting chamber. The setting mechanism holds the shaped profile under pressure to ensure that the profile retains its shaped form during the cooling process. Internal stress is applied until the profile is completely cured and formed. After the above process is completed, the forming device can be moved back to the molding area by the transfer mechanism for the next round of processing, while the cured profile is taken out and prepared for subsequent processing or assembly. Among them, radio frequency heating has universality and can be used to heat various types of wood boards. The uniform and rapid heating characteristics of radio frequency heating, combined with the precise control of vacuum technology, can significantly improve the processing efficiency of profiles, reduce the processing cycle, and improve the overall quality, stability and yield of profiles during the processing. At the same time, multiple molding chambers are set along the height direction in the molding area to simultaneously hold and shape the profiles after molding in multiple molding chambers, improve the space utilization of the workshop and further improve the processing efficiency.
[0012] Optionally, the molding mechanism includes:
[0013] Negative pressure branch pipes are installed on the support platform, and multiple pipes are installed and connected to the interior of the molding chamber;
[0014] A negative pressure main pipeline is located between multiple negative pressure branch pipelines and is connected to all of the multiple negative pressure branch pipelines. A first electrically controlled valve is installed on the negative pressure main pipeline.
[0015] A first vacuum pump device is located in the molding area;
[0016] A docking support is connected to the first vacuum pump device;
[0017] A quick-connect assembly is disposed between the docking support and the negative pressure main pipeline to enable a quick connection between the docking support and the negative pressure main pipeline;
[0018] A fixing frame is disposed between the cover and the molding chamber and is hinged to the molding chamber; a gas spring is also disposed between the fixing frame and the molding chamber.
[0019] A flexible molding film is disposed on the fixed frame and located above the mold;
[0020] A fixing component is disposed between the fixing frame and the flexible molding film, for fixing the flexible molding film to the fixing frame.
[0021] By adopting the above technical solution, when processing the profile through the molding mechanism, the profile to be processed is first placed on top of the mold on the support platform. Then, the fixing frame is snapped down, allowing the flexible molding film to cover the top of the profile. Subsequently, the cover is closed, the first electrically controlled valve is opened, and the first vacuum pump device is started simultaneously. Through the negative pressure main pipe and multiple negative pressure branch pipes, a vacuum is drawn between the flexible molding film and the support platform to form a negative pressure environment. As the negative pressure environment is formed and the profile is heated by the radio frequency heater, the flexible molding film adheres tightly to the profile under the negative pressure and applies pressure, causing the profile and mold to gradually... The material is tightly pressed against the mold, gradually shaping it into a form that matches the mold. Once the material is shaped to the desired form, the first electrically controlled valve closes, and the first vacuum pump stops working. The quick-connect assembly is used to enable the rapid connection between the negative pressure main pipe and the first vacuum pump after switching between the forming device in the molding zone and the forming device in the shaping chamber. Under negative pressure, the flexible molding film adheres tightly to the material, ensuring close contact between the material and the mold, improving the precision and consistency of the molding process. Furthermore, when the flexible molding film ages or wears, workers can quickly replace or repair it using the fixing assembly.
[0022] Optionally, the fixing component includes:
[0023] A bracket is fixed to the fixed frame, and multiple brackets are provided and distributed at intervals along the circumference of the fixed frame. A pressure plate is provided between the bracket and the fixed frame, and the flexible plastic film abuts against the pressure plate and the fixed frame.
[0024] A damping rod is disposed between the pressure plate and the bracket, and multiple damping rods are spaced apart along the length of the pressure plate. One end of the damping rod is fixedly connected to the pressure plate.
[0025] A compression spring is sleeved on the outside of the damping rod and applies a force to the pressure plate to move toward one side of the fixed frame;
[0026] A first electrically driven telescopic rod is disposed between the pressure plate and the bracket;
[0027] Positioning components are disposed between the fixed frame and the flexible plastic film. Multiple components are provided and distributed at intervals along the circumference of the fixed frame to position the flexible plastic film.
[0028] By adopting the above technical solution, before replacing the flexible molding film, the pressure plate continuously applies pressure to the flexible molding film under the action of the compression spring, so that the flexible molding film is firmly fixed between the fixed frame and the pressure plate. When the operator needs to replace or repair the flexible molding film, the operator moves the pressure plate away from the fixed frame by operating the first electric drive telescopic rod, which releases the pressure plate from fixing the flexible molding film. Then, the operator places the new flexible molding film between the fixed frame and the pressure plate, and uses the positioning component to accurately position the flexible molding film to ensure its accurate installation position and prevent misalignment or tilting during the fixing process. Then, the first electric drive telescopic rod is released from the pressure plate. The fixing and clamping spring immediately applies a force to the pressure plate, moving it towards the fixed frame, pressing the flexible molding film between the pressure plate and the fixed frame, thus realizing the replacement process of the flexible molding film. The positioning component allows the operator to quickly and accurately position the flexible molding film during installation or replacement, improving the convenience and efficiency of operation, simplifying the replacement or maintenance process of the flexible molding film, reducing equipment maintenance costs and downtime, improving molding accuracy and consistency, and reducing the scrap rate during processing. At the same time, the damping rod and clamping spring ensure smooth movement of the pressure plate, allowing the operator to easily control the fixing and releasing of the flexible molding film, improving the convenience and safety of operation.
[0029] Optionally, the end of the damping rod away from the pressure plate is detachably connected to the bracket.
[0030] By adopting the above technical solution, the compression spring is a consumable part, and the end of the damping rod away from the pressure plate is detachably connected to the bracket. This allows the compression spring or damping rod to be easily disassembled when it is damaged, aged, or needs to be replaced, reducing maintenance difficulty and cost. Furthermore, different specifications of damping rods or compression springs can be replaced according to different processing requirements or the thickness of the flexible plastic film, improving the adaptability and flexibility of the equipment.
[0031] Optionally, the positioning component includes a second electrically driven telescopic rod with one end connected to the fixed frame and an electric gripper disposed at the other end of the second electrically driven telescopic rod, the electric gripper being used to hold the flexible molding film.
[0032] By adopting the above technical solution, when replacing or installing flexible molding film, workers can accurately measure the clamping points of the flexible molding film and mark them with measuring tools. The electric gripper can accurately clamp the marked points on the flexible molding film, thereby ensuring its accurate position on the fixed frame and preventing misalignment or skewing during the molding process.
[0033] Optionally, the quick-connect component includes:
[0034] Quick-connect fittings are spaced apart on one side of the negative pressure main pipeline;
[0035] A drive cylinder is fixed between the quick-connect seat and the docking support;
[0036] A telescopic pipe is fixedly installed between the quick-connect seat and the docking support;
[0037] A rotating pipe is rotatably connected to the quick-connect seat on the side near the negative pressure main pipe, and the rotating pipe, the telescopic pipe, and the first vacuum pump device are all connected.
[0038] Multiple lock seats are provided and fixed to the outside of the rotating pipe or the telescopic pipe. Lock blocks corresponding to the multiple lock seats are fixed to the outside of the rotating pipe or the telescopic pipe. Lock holes adapted to the corresponding lock blocks are provided on the lock seats. When the lock blocks are inserted into the lock holes, the rotating pipe and the negative pressure main pipe are sealed together.
[0039] A drive gear ring is fixedly sleeved on the outside of the rotating pipe;
[0040] A drive motor is mounted on the quick-connect bracket, and a drive gear is fixedly sleeved on the output shaft of the drive motor. The drive gear meshes with the drive gear ring.
[0041] By adopting the above technical solution, when the quick-connect assembly is in an unconnected state, the rotating pipe is separated from the negative pressure main pipe, and the locking block is not inserted into the locking hole of the locking seat. When connecting the rotating pipe and the negative pressure main pipe through the quick-connect assembly, the operator first aligns the rotating pipe with the negative pressure main pipe, then starts the drive cylinder to push the telescopic pipe to extend, bringing the rotating pipe closer to the negative pressure main pipe. Subsequently, the drive motor is started, driving the gear to rotate. Through meshing with the drive gear ring, the rotating pipe is driven to rotate. During the rotation, the locking block aligns with the locking hole on the locking seat. When the locking block is inserted into the locking hole, the rotating pipe and the negative pressure main pipe can achieve a sealed connection. In this way, the cooperation between the telescopic pipe and the rotating pipe realizes the quick connection between the negative pressure main pipe and the first vacuum pump device, greatly shortening the equipment preparation time. Moreover, the cooperation between the locking block and the locking seat ensures the sealing between the rotating pipe and the negative pressure main pipe, avoiding negative pressure leakage and improving operational stability. At the same time, the telescopic pipe can adapt to the connection requirements of different positions and angles, improving the adaptability and flexibility of the equipment.
[0042] Optionally, a limiting block is fixed at one end of the locking block.
[0043] By adopting the above technical solution, the limiting block is used to limit the rotation angle of the rotating pipe, prevent the locking block from rotating excessively during the rotation process, realize the sealed connection between the rotating pipe and the negative pressure main pipe, and make it so that when the operator connects the rotating pipe and the negative pressure main pipe, there is no need to adjust the rotation angle too much, reducing the difficulty of operation and improving the ease and efficiency of operation.
[0044] Optionally, the locking block has a chamfer on the side away from the limiting block.
[0045] By adopting the above technical solution, the chamfer can guide the lock block to be inserted more easily into the lock hole on the lock seat, and can also apply a certain pre-tightening pressure to the connection between the rotating pipe and the negative pressure main pipe, thereby improving the sealing of the connection.
[0046] Optionally, the shaping mechanism includes a second vacuum pump device disposed within the shaping area. The second vacuum pump device is also provided with the docking support. A second electrically controlled valve is also provided on the negative pressure main pipeline. A quick-connect assembly is also provided between the docking support on the second vacuum pump device and the negative pressure main pipeline.
[0047] By adopting the above technical solution, the second vacuum pump device is used to maintain the pressure of the profile in the forming device within the shaping zone. The power requirement of the second vacuum pump device is much smaller than that of the first vacuum pump device. Therefore, under the premise of meeting the pressure maintenance requirements of the shaping zone, selecting a vacuum pump device with lower power can effectively reduce the purchase and operating costs of the equipment. Moreover, the pressure maintenance in the shaping zone usually requires more precise negative pressure control, and the vacuum pump device with lower power can provide more accurate negative pressure adjustment. At the same time, the second vacuum pump device is also equipped with a docking support, and it is also connected to the negative pressure main pipeline using quick-connect components, thereby ensuring a quick and sealed connection between the second vacuum pump device and the negative pressure main pipeline, improving the response speed and operating efficiency of the equipment.
[0048] Optionally, the shifting mechanism includes a lifting machine disposed in the molding area, the lifting machine including a lifting platform, a first conveyor disposed on the lifting platform, and the molding device can be placed on the first conveyor;
[0049] Each of the shaping chambers in the shaping area is provided with a second conveyor, and the forming device can be placed on the second conveyor.
[0050] By adopting the above technical solution, the shifting mechanism is used to realize the transfer of the molding device on the molding zone and the shaping zone. The lifting machine is used to drive the molding device to move vertically between different heights, while the first conveyor and the second conveyor are used to move the molding device laterally in the lifting platform and the shaping chamber, so as to realize the efficient transfer of the molding device between the molding zone and the shaping zone and continuous production.
[0051] In summary, this application includes at least one of the following beneficial technical effects:
[0052] 1. Radio frequency (RF) heating is versatile and can be used to heat various types of wood boards. The uniform and rapid heating characteristics of RF heating, combined with the precise control of vacuum technology, can significantly improve the processing efficiency of profiles, reduce the processing cycle, and improve the overall quality, stability, and yield of profiles during processing. At the same time, multiple shaping chambers are set along the height direction in the shaping area, which can simultaneously hold and shape the profiles after they have been shaped in multiple forming chambers, improving the space utilization of the workshop and further improving processing efficiency.
[0053] 2. The quick-connect component in the molding mechanism is used to enable the rapid connection between the negative pressure main pipe and the first vacuum pump device after switching between the molding device in the molding zone and the molding device in the shaping chamber. Under the action of negative pressure, the flexible molding film is tightly attached to the profile, ensuring close contact between the profile and the mold, improving the precision and consistency of molding. When the flexible molding film ages or wears, the staff can quickly replace or repair the flexible molding film through the fixing component.
[0054] 3. The positioning components in the fixing assembly enable workers to quickly and accurately position the flexible molding film during installation or replacement, improving operational convenience and efficiency. This simplifies the replacement and maintenance process, reduces equipment maintenance costs and downtime, enhances molding accuracy and consistency, and reduces scrap rates. Simultaneously, the damping rod and clamping spring ensure smooth movement of the pressure plate, allowing workers to easily control the fixing and releasing of the flexible molding film, improving operational convenience and safety. The clamping spring is a consumable part, and the end of the damping rod furthest from the pressure plate is detachably connected to the bracket. This allows for easy disassembly of the clamping spring or damping rod when damaged, aged, or requiring replacement, reducing maintenance difficulty and costs. Furthermore, different specifications of damping rods or clamping springs can be replaced according to different processing requirements or the thickness of the flexible molding film, improving the equipment's adaptability and flexibility.
[0055] 4. When replacing or installing flexible molding film, workers can use measuring tools to accurately measure the clamping points of the flexible molding film and mark them. The electric gripper can accurately clamp the marked points on the flexible molding film, thereby ensuring its accurate position on the fixed frame and preventing misalignment or skewing during the molding process.
[0056] 5. The quick-connect assembly achieves a rapid connection between the negative pressure main pipeline and the first vacuum pump device through the cooperation of the telescopic pipe and the rotating pipe, which greatly shortens the equipment preparation time. In addition, the cooperation of the locking block and the locking seat ensures the sealing between the rotating pipe and the negative pressure main pipeline, avoids negative pressure leakage, and improves the stability of operation. At the same time, the telescopic pipe can adapt to the connection requirements of different positions and angles, improving the adaptability and flexibility of the equipment.
[0057] 6. The second vacuum pump unit is used to maintain pressure on the profiles in the forming device within the shaping zone. The power requirement of the second vacuum pump unit is much lower than that of the first vacuum pump unit. Therefore, under the premise of meeting the pressure maintenance requirements of the shaping zone, selecting a vacuum pump unit with lower power can effectively reduce the purchase and operating costs of the equipment. Moreover, the pressure maintenance in the shaping zone usually requires more precise negative pressure control, and the vacuum pump unit with lower power can provide more accurate negative pressure adjustment. At the same time, the second vacuum pump unit is also equipped with a docking support, and it is also connected to the negative pressure main pipeline using quick-connect components, thereby ensuring a quick and sealed connection between the second vacuum pump unit and the negative pressure main pipeline, improving the response speed and operating efficiency of the equipment.

[0067] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.
[0068] After reading this specification, those skilled in the art may make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
[0069] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0070] This application discloses a multi-functional radio frequency vacuum integrated machine for processing door and wall cabinets. (Refer to...) Figure 1 and Figure 2 The system includes a frame 1, on which multiple molding devices 2 are mounted. Each molding device 2 includes a molding chamber 21, a support platform 22 fixed within the molding chamber 21, a mold 23 positioned above the support platform 22, a cover 24 positioned on top of the molding chamber 21, and multiple radio frequency heaters 25 positioned on the cover 24. The frame 1 includes a molding area 11 and a shaping area 12. The shaping area 12 contains multiple shaping chambers 121, which are spaced apart along the height of the frame 1. Each shaping chamber 121 corresponds one-to-one with a molding device 2, with one molding device 2 located in the molding area 11 and the remaining molding devices 2 located in the shaping chambers 121. The multi-functional radio frequency vacuum integrated machine for door and wall cabinet processing also includes a molding device, which includes a molding mechanism 3, a shaping mechanism 4, and a shifting mechanism 5. The molding mechanism 3 is located between the molding chamber 21 and the molding area 11, and is used to mold the profile in the molding chamber 21 into a shape that matches the mold 23 under vacuum conditions through the mold 23. The setting mechanism 4 is located between the molding chamber 21 and the setting area 12, and is used to hold and set the molded profile in the molding chamber 21. The shifting mechanism 5 is located between the molding area 11 and the setting area 12, and is used to move and interchange the molding device 2 in the molding area 11 and the setting area 12.
[0071] When processing the profile, the profile to be processed is first placed on the support platform 22 of the molding device 2 in the molding zone 11, above the mold 23. Then, the cover 24 is closed to form a closed molding chamber 21. The radio frequency heater 25 starts working, rapidly and evenly heating the profile to soften the internal fiber structure. Simultaneously with the radio frequency heating, the molding mechanism 3 is activated to create a vacuum inside the molding chamber 21, gradually bringing the profile closer to the mold 23. Under vacuum, the profile is shaped by the mold 23 to form a shape that fits the mold 23. Then, the shifting mechanism 5 is activated to move the shaped molding device 2 from the molding zone 11 to the setting chamber 121. The setting mechanism 4 holds the shaped profile under pressure to ensure that it maintains its shape during cooling, eliminating internal stress, until the profile is completely cured. After the above process is completed, the molding device 2 can be moved back to the molding area 11 by the transfer mechanism 5 for the next round of processing, while the solidified profile is taken out, ready for subsequent processing or assembly. Radio frequency heating is universal and can be used to heat various types of wood boards. The uniform and rapid heating characteristics of radio frequency heating, combined with the precise control of vacuum technology, can significantly improve the processing efficiency of the profiles, reduce the processing cycle, and improve the overall quality, stability, and yield of the profiles during processing. Simultaneously, multiple molding chambers 121 are arranged along the height direction in the molding area 12, which can simultaneously hold and shape the molded profiles in multiple molding chambers 21, improving the space utilization of the workshop and further increasing processing efficiency.
[0072] Reference Figure 1 and Figure 2 The shifting mechanism 5 includes a lifting machine 51 disposed in the molding area 11, and the lifting machine 51 includes a lifting platform 52. A first conveyor 53 is disposed on the lifting platform 52, and the molding device 2 can be placed on the first conveyor 53. A second conveyor 54 is disposed in each molding chamber 121 in the molding area 12, and the molding device 2 can be placed on the second conveyor 54.
[0073] The shifting mechanism 5 is used to realize the transfer of the molding device 2 on the molding zone 11 and the shaping zone 12. The lifting machine 51 is used to drive the molding device 2 to move vertically between different heights, while the first conveyor 53 and the second conveyor 54 are used to move the molding device 2 laterally in the lifting platform 52 and the shaping chamber 121, so as to realize the efficient transfer and continuous production of the molding device 2 between the molding zone 11 and the shaping zone 12.
[0074] Reference Figures 2-4The molding mechanism 3 includes multiple negative pressure branch pipes 31 mounted on the support platform 22, which are connected to the interior of the molding chamber 21. A negative pressure main pipe 32 is provided between the multiple negative pressure branch pipes 31, and the negative pressure main pipe 32 is connected to all the multiple negative pressure branch pipes 31. A first electrically controlled valve is also provided on the negative pressure main pipe 32. A first vacuum pump device 33 is provided in the molding area 11, and a docking support 34 is connected to the first vacuum pump device 33. A quick-connect assembly 35 is provided between the docking support 34 and the negative pressure main pipe 32 to achieve a quick connection between the docking support 34 and the negative pressure main pipe 32. A fixing frame 36 is provided between the cover 24 and the molding chamber 21, and the fixing frame 36 is hinged to the molding chamber 21. A gas spring 37 is also provided between the fixing frame 36 and the molding chamber 21. A flexible molding film 38 is provided on the fixed frame 36, and the flexible molding film 38 is located above the mold 23. The flexible molding film 38 is made of silicone material. A fixing component 39 is provided between the fixed frame 36 and the flexible molding film 38, and the fixing component 39 is used to fix the flexible molding film 38 into the fixed frame 36.
[0075] When processing the profile using the molding mechanism 3, the profile to be processed is first placed on the support platform 22 above the mold 23. Then, the fixing frame 36 is snapped down, allowing the flexible molding film 38 to cover the top of the profile. Next, the cover 24 is closed, the first electrically controlled valve is opened, and the first vacuum pump device 33 is started simultaneously. A vacuum is created between the flexible molding film 38 and the support platform 22 through the main negative pressure pipe 32 and multiple negative pressure branch pipes 31, forming a negative pressure environment. As the negative pressure environment is formed and the radio frequency heater 25 heats the profile, the flexible molding film 38 adheres tightly to the profile under the negative pressure and applies pressure, causing the profile to gradually come into close contact with the mold 23, thus gradually shaping the profile into a shape compatible with the mold 23. Once the profile has been shaped to the desired form, the first electrically controlled valve is closed, and the first vacuum pump device 33 stops operating. The quick-connect component 35 is used to enable the rapid connection between the negative pressure main pipe 32 and the first vacuum pump device 33 after the switching between the molding device 2 in the molding zone 11 and the molding device 2 in the shaping chamber 121. The flexible molding film 38 is tightly attached to the profile under the action of negative pressure, ensuring close contact between the profile and the mold 23, improving the accuracy and consistency of molding. When the flexible molding film 38 ages or wears, the staff can quickly replace or repair the flexible molding film 38 through the fixing component 39.
[0076] Reference Figure 4 and Figure 5The fixing component 39 includes multiple brackets 391 fixed to the fixing frame 36, with the brackets 391 spaced apart circumferentially along the fixing frame 36. A pressure plate 392 is disposed between the brackets 391 and the fixing frame 36, and a flexible plastic film 38 simultaneously abuts against the pressure plate 392 and the fixing frame 36. A damping rod 393 is disposed between the pressure plate 392 and the brackets 391, with multiple damping rods 393 spaced apart along the length of the pressure plate 392. One end of the damping rod 393 is fixedly connected to the pressure plate 392, and the other end is detachably connected to the bracket 391 by bolts. A compression spring 394 is sleeved on the outside of the damping rod 393, and the compression spring 394 applies a force to the pressure plate 392 to move towards one side of the fixing frame 36. A first electrically driven telescopic rod 395 is provided between the pressure plate 392 and the bracket 391. A plurality of positioning components 396 are provided between the fixed frame 36 and the flexible plastic film 38. The plurality of positioning components 396 are distributed at intervals along the circumference of the fixed frame 36, and the positioning components 396 are used to position the flexible plastic film 38.
[0077] Before replacing the flexible molding film 38, the pressure plate 392, under the action of the compression spring 394, continuously applies pressure to the flexible molding film 38, firmly fixing it between the fixing frame 36 and the pressure plate 392. When the operator needs to replace or repair the flexible molding film 38, the operator moves the pressure plate 392 away from the fixing frame 36 by operating the first electric drive telescopic rod 395, thus releasing the pressure plate 392 from fixing the flexible molding film 38. Then, the operator places the new flexible molding film 38 between the fixing frame 36 and the pressure plate 392, and uses the positioning component 396 to precisely position the flexible molding film 38, ensuring accurate installation and preventing misalignment or tilting during the fixing process.
[0078] Subsequently, the first electric drive telescopic rod 395 releases its fixation to the pressure plate 392. The clamping spring 394 immediately applies a force to the pressure plate 392, moving it towards the fixed frame 36, thus pressing the flexible molding film 38 between the pressure plate 392 and the fixed frame 36, completing the replacement process of the flexible molding film 38. The positioning component 396 allows operators to quickly and accurately position the flexible molding film 38 during installation or replacement, improving operational convenience and efficiency. It also simplifies the replacement or maintenance process of the flexible molding film 38, reducing equipment maintenance costs and downtime, improving molding accuracy and consistency, and reducing the scrap rate during processing. Simultaneously, the damping rod 393 and the clamping spring 394 ensure smooth movement of the pressure plate 392, allowing operators to easily control the fixing and releasing of the flexible molding film 38, improving operational convenience and safety. The compression spring 394 is a consumable part. The end of the damping rod 393 away from the pressure plate 392 is detachably connected to the bracket 391 by bolts. This allows the compression spring 394 or the damping rod 393 to be easily disassembled when damaged, aged, or needing replacement, reducing maintenance difficulty and cost. Furthermore, different specifications of damping rod 393 or compression spring 394 can be replaced according to different processing requirements or the thickness of the flexible plastic film 38, improving the adaptability and flexibility of the equipment.
[0079] Reference Figure 4 and Figure 5 The positioning component includes a second electrically driven telescopic rod 3961 with one end connected to the fixed frame 36 and an electric gripper 3962 disposed at the other end of the second electrically driven telescopic rod 3961. The electric gripper 3962 is used to clamp the flexible plastic film 38.
[0080] When replacing or installing the flexible molding film 38, the staff can use measuring tools to accurately measure the clamping points of the flexible molding film 38 and mark them. The electric gripper 3962 can accurately clamp the marked points on the flexible molding film 38, thereby ensuring its accurate position on the fixed frame 36 and preventing misalignment or skew during the molding process.
[0081] Reference Figure 6 and Figure 7The quick-connect assembly 35 includes quick-connect seats 351 spaced apart on one side of the negative pressure main pipe 32. A drive cylinder 352 is fixed between the quick-connect seat 351 and the docking support 34. A telescopic pipe 353 is also fixed between the quick-connect seat 351 and the docking support 34. A rotating pipe 354 is rotatably connected to the side of the quick-connect seat 351 near the negative pressure main pipe 32. The rotating pipe 354, the telescopic pipe 353, and the first vacuum pump device 33 are all connected. Multiple locking seats 355 are fixed on the outside of the rotating pipe 354 or the outside of the telescopic pipe 353. Locking blocks 356 corresponding to the multiple locking seats 355 are fixed on the outside of the rotating pipe 354 or the outside of the telescopic pipe 353. Locking holes 3551 adapted to the corresponding locking blocks 356 are opened on the locking seats 355. When the locking blocks 356 are inserted into the locking holes 3551, the rotating pipe 354 and the negative pressure main pipe 32 are sealed together.
[0082] Reference Figure 7 and Figure 8 A limiting block 357 is fixed to one end of the locking block 356. The limiting block 357 is used to limit the rotation angle of the rotating pipe 354, preventing the locking block 356 from rotating excessively during rotation, thus achieving a sealed connection between the rotating pipe 354 and the negative pressure main pipe 32. This also reduces the need for excessive adjustment of the rotation angle when connecting the rotating pipe 354 and the negative pressure main pipe 32, lowering the operational difficulty and improving ease and efficiency. A chamfer 3561 is provided on the side of the locking block 356 away from the limiting block 357. The chamfer 3561 guides the locking block 356 to more easily insert into the locking hole 3551 on the locking seat 355, and also applies a certain pre-tightening pressure to the connection between the rotating pipe 354 and the negative pressure main pipe 32, improving the sealing performance of the connection. A drive gear ring 358 is fixedly sleeved on the outside of the rotating pipe 354. A drive motor 359 is installed on the quick-connect seat 351. A drive gear 3510 is fixedly sleeved on the output shaft of the drive motor 359. The drive gear 3510 meshes with the drive gear ring 358.
[0083] When the quick-connect assembly 35 is not connected, the rotating pipe 354 is separated from the negative pressure main pipe 32, and the locking block 356 is not inserted into the locking hole 3551 of the lock seat 355. When connecting the rotating pipe 354 and the negative pressure main pipe 32 through the quick-connect assembly 35, the operator first aligns the rotating pipe 354 with the negative pressure main pipe 32, then starts the drive cylinder 352 to push the telescopic pipe 353 to extend, bringing the rotating pipe 354 closer to the negative pressure main pipe 32. Subsequently, the drive motor 359 is started, driving the gear 3510 to rotate. Through meshing with the drive gear ring 358, the rotating pipe 354 is driven to rotate. During the rotation, the locking block 356 aligns with the locking hole 3551 on the lock seat 355. When the locking block 356 is inserted into the locking hole 3551, the rotating pipe 354 and the negative pressure main pipe 32 can achieve a sealed connection. The cooperation of the telescopic pipe 353 and the rotating pipe 354 enables a rapid connection between the negative pressure main pipe 32 and the first vacuum pump device 33, significantly shortening the equipment preparation time. Furthermore, the cooperation of the locking block 356 and the locking seat 355 ensures the sealing between the rotating pipe 354 and the negative pressure main pipe 32, preventing negative pressure leakage and improving operational stability. Simultaneously, the telescopic pipe 353 can adapt to connection requirements at different positions and angles, enhancing the adaptability and flexibility of the equipment.
[0084] Reference Figure 6 and Figure 7 The shaping mechanism 4 includes a second vacuum pump device 41 disposed in the shaping area 12. The second vacuum pump device 41 is also provided with a docking support 34. The negative pressure main pipeline 32 is also provided with a second electrically controlled valve. A quick-connect component 35 is also provided between the docking support 34 on the second vacuum pump device 41 and the negative pressure main pipeline 32.
[0085] The second vacuum pump device 41 is used to maintain pressure on the profile in the forming device 2 within the shaping zone 12. The power requirement of the second vacuum pump device 41 is much lower than that of the first vacuum pump device 33. Therefore, under the premise of meeting the pressure maintenance requirements of the shaping zone 12, selecting a vacuum pump device with lower power can effectively reduce the purchase and operating costs of the equipment. Moreover, the pressure maintenance in the shaping zone 12 usually requires more precise negative pressure control, and the vacuum pump device with lower power can provide more accurate negative pressure adjustment. At the same time, the second vacuum pump device 41 is also equipped with a docking support 34, and is also connected to the negative pressure main pipe 32 using a quick-connect component 35, thereby ensuring a quick and sealed connection between the second vacuum pump device 41 and the negative pressure main pipe 32, improving the response speed and operating efficiency of the equipment.
[0086] The implementation principle of a multi-functional radio frequency vacuum integrated machine for door and wall cabinet processing in this application embodiment is as follows: Radio frequency heating has universality and can be used to heat various types of wood boards. The uniform and rapid heating characteristics of radio frequency heating, combined with the precise control of vacuum technology, can significantly improve the processing efficiency of profiles, reduce the processing cycle, and improve the overall quality, stability, and yield of profiles during the processing. At the same time, multiple shaping chambers 121 are set along the height direction in the shaping area 12, which can simultaneously hold and shape the profiles after molding in multiple forming chambers 21, improve the space utilization of the workshop, and further improve the processing efficiency.
[0087] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
