[0002] Radio frequency heating is a technology that uses electromagnetic waves with frequencies ranging from 3 kHz to 300 MHz to heat materials. This heating method has many advantages: the rate of radio frequency heating is very fast, and the high-frequency alternating electromagnetic waves can quickly cause the molecules in the material to move at a high speed, achieving the effect of rapid heating. This heating method also has the characteristics of overall internal and external heating, which can ensure that the material is evenly heated and avoid local overheating or non-heating.

[0003] Currently, with the increasing popularity of customized furniture, various special-shaped furniture has emerged. Among them, in the processing of doors, walls and cabinets, it is necessary to press or bend wooden boards into curved boards or bent corners with a certain arc surface or angle. The traditional processing method is to use a hot press to heat and soften the wooden boards through steam or hot air, making the internal fiber structure soft and facilitating subsequent curing and forming. However, the hot press has a single function. The processing method using a hot press not only has low processing efficiency, but also the overall temperature inside and outside the wooden board is uneven after heating. The hot pressing process is greatly affected by the external temperature and has a high cost. Summary of the Invention

The forming device includes a forming chamber, a bearing table fixedly arranged in the forming chamber, a mold arranged above the bearing table, a cover arranged on the top of the forming chamber, and multiple radio frequency heaters arranged on the cover; wherein a shaping area and a sizing area are arranged on the frame. Multiple sizing chambers are arranged in the sizing area. The multiple sizing chambers are spaced apart along the height direction of the frame, and the multiple sizing chambers correspond to the multiple forming devices one by one. One of the forming devices is located in the shaping area, and the rest of the forming devices are located in the sizing chambers; and further includes: Plastic shaping device, the plastic shaping device includes a plastic shaping mechanism, a shaping and setting mechanism, and a displacement mechanism; the plastic shaping mechanism is arranged between the shaping bin and the plastic shaping area, and is used for shaping the profile in the shaping bin into a shape adapted to the mold under a vacuum state through the mold; the shaping and setting mechanism is arranged between the shaping bin and the shaping and setting area, and is used for pressure maintaining and setting of the shaped profile in the shaping bin; the displacement mechanism is arranged between the plastic shaping area and the shaping and setting area, and is used for moving and exchanging the shaping devices in the plastic shaping area and the shaping and setting area.

[0006] By adopting the above technical solution, when processing the profile, first place the profile to be processed above the mold on the carrier table of the shaping device in the plastic shaping area, then close the cover to form a closed shaping bin, and the radio frequency heater starts to work to rapidly and uniformly heat the profile, so that the fiber structure inside the profile is softened. While the radio frequency heating is in progress, the plastic shaping mechanism is activated to evacuate the inside of the shaping bin, and at the same time, the profile is gradually closely attached to the mold. The profile is shaped through the mold under a vacuum state to form a shape adapted to the mold. Subsequently, the displacement mechanism is activated to move the shaped shaping device from the plastic shaping area to the shaping and setting chamber, and the shaping and setting mechanism performs pressure maintaining and setting on the shaped profile to ensure that the profile maintains the shaped shape during the cooling process and eliminates internal stress until the profile is completely solidified and formed; after the above process is completed, the shaping device can be moved back to the plastic shaping area by the displacement mechanism for the next round of processing, and the solidified and formed 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 different types of wooden boards.

Through the negative pressure main pipeline and multiple negative pressure branch pipelines, vacuum is pumped between the flexible shaping film and the bearing table to form a negative pressure environment. With the formation of the negative pressure environment and the heating treatment of the profile by the radio frequency heater, the flexible shaping film closely adheres to the profile under the action of negative pressure and applies pressure, so that the profile gradually and closely abuts against the mold, thereby gradually shaping the profile to form a shape adapted to the mold. When the profile is shaped to the required shape, the first electric control valve is closed and the first vacuum pump device stops working; among them, the quick-connect component is used to realize the quick docking of the negative pressure main pipeline and the first vacuum pump device after switching the forming device in the shaping area and the forming device in the sizing chamber, and the flexible shaping film closely adheres to the profile under the action of negative pressure, ensuring the close contact between the profile and the mold, improving the shaping accuracy and consistency, and when the flexible shaping film ages or wears, the staff can quickly replace or repair the flexible shaping film through the fixing component.

Then, the staff places a new flexible shaping film between the fixed frame and the pressing plate, and accurately positions the flexible shaping film through the positioning component to ensure its accurate installation position and prevent misalignment or skew during the fixation process. Subsequently, the fixation of the first electric drive telescopic rod on the pressing plate is released, and the compression spring immediately gives the pressing plate a force to move towards the fixed frame side, pressing the flexible shaping film tightly between the pressing plate and the fixed frame, thus realizing the replacement process of the flexible shaping film; the positioning component enables the staff to quickly and accurately position when installing or replacing the flexible shaping film, improves the convenience and efficiency of the operation, makes the replacement or repair process of the flexible shaping film simpler, reduces the maintenance cost and downtime of the equipment, improves the shaping accuracy and consistency, reduces the scrap rate during the processing, and at the same time, the damping rod and the compression spring make the movement of the pressing plate stable, and the staff can easily control the fixation and release of the flexible shaping film, improving the convenience and safety of the operation.

The driving gear rotates, and drives the rotating pipe to rotate through meshing with the driving gear ring. During the rotation process, the locking block is aligned with the locking hole on the locking seat.

At the same time, the telescopic pipeline can adapt to the connection requirements of different positions and angles, improving the adaptability and flexibility of the equipment. 6. The second vacuum pump device is used to maintain the pressure of the profiles in the forming device in the sizing area. The power requirement of the second vacuum pump device is much smaller than that of the first vacuum pump device. Therefore, on the premise of meeting the pressure maintenance requirement in the sizing area, selecting a vacuum pump device with less power can effectively reduce the equipment purchase cost and operation cost.

[0038] Before replacing the flexible shaping film 38, the pressing plate 392 continuously applies pressure to the flexible shaping film 38 under the action of the pressing spring 394, so that the flexible shaping film 38 is firmly fixed between the fixed frame 36 and the pressing plate 392. When the staff needs to replace or repair the flexible shaping film 38, the staff operates the first electric drive telescopic rod 395 to drive the pressing plate 392 to move away from the fixed frame 36, and the fixation of the pressing plate 392 on the flexible shaping film 38 can be released. Then the staff places the new flexible shaping film 38 between the fixed frame 36 and the pressing plate 392, and precisely positions the flexible shaping film 38 through the positioning component 396 to ensure its accurate installation position and prevent dislocation or skew during the fixation process.

[0039] Subsequently, the fixation of the first electric drive telescopic rod 395 on the pressing plate 392 is released, and the pressing spring 394 immediately gives the pressing plate 392 a force to move towards the fixed frame 36, pressing the flexible shaping film 38 between the pressing plate 392 and the fixed frame 36 to complete the replacement process of the flexible shaping film 38. The positioning component 396 enables the staff to quickly and accurately position when installing or replacing the flexible shaping film 38, improving the convenience and efficiency of the operation, making the replacement or repair process of the flexible shaping film 38 simpler, reducing the equipment maintenance cost and downtime, improving the shaping accuracy and consistency, and reducing the scrap rate during the processing. At the same time, the damping rod 393 and the pressing spring 394 make the movement of the pressing plate 392 stable, and the staff can easily control the fixation and release of the flexible shaping film 38, improving the convenience and safety of the operation. The pressing spring 394 is a vulnerable part. One end of the damping rod 393 away from the pressing plate 392 is detachably connected to the bracket 391 through bolts, so that the pressing spring 394 or the damping rod 393 can be easily disassembled when damaged, aged or in need of replacement, reducing the maintenance difficulty and cost, and different specifications of the damping rod 393 or the pressing spring 394 can be replaced according to different processing requirements or the thickness of the flexible shaping film 38, improving the adaptability and flexibility of the equipment.

[0040] Refer to Figure 4 and Figure 5 As shown in FIGS. and, the positioning assembly includes a second electric drive telescopic rod 3961 with one end connected to the fixed frame 36 and an electric gripper 3962 arranged at the other end of the second electric drive telescopic rod 3961. The electric gripper 3962 is used to grip the flexible shaping film 38.

[0041] When replacing or installing the flexible shaping film 38, the staff can accurately measure the clamping point of the flexible shaping film 38 with a measuring tool and mark it with a line. The electric gripper 3962 can accurately grip the marked point on the flexible shaping film 38, thereby ensuring its accurate position on the fixed frame 36 and preventing dislocation or skew during the shaping process.

[0042] Refer to Figure 6 andFigure 7 , the quick-connect component 35 includes a quick-connect seat 351 spaced on one side of the main negative-pressure pipeline 32. A driving cylinder 352 is fixedly arranged between the quick-connect seat 351 and the docking support 34, and a telescopic pipeline 353 is also fixedly arranged between the quick-connect seat 351 and the docking support 34. A rotating pipeline 354 is rotatably connected to one side of the quick-connect seat 351 close to the main negative-pressure pipeline 32. The rotating pipeline 354, the telescopic pipeline 353, and the first vacuum pump device 33 are all connected in communication. A plurality of locking seats 355 are fixedly arranged on the outer side of the rotating pipeline 354 or the outer side of the telescopic pipeline 353. A locking block 356 corresponding to each of the plurality of locking seats 355 is fixedly arranged on the outer side of the rotating pipeline 354 or the outer side of the telescopic pipeline 353. A locking hole 3551 adapted to the corresponding locking block 356 is formed in the locking seat 355. When the locking block 356 is inserted into the locking hole 3551, the rotating pipeline 354 is hermetically docked with the main negative-pressure pipeline 32.

[0043] Refer to Figure 7 and Figure 8 , a limiting block 357 is fixedly arranged at one end of the locking block 356. The limiting block 357 is used to limit the rotation angle of the rotating pipeline 354, prevent the locking block 356 from rotating excessively during rotation, realize the hermetic docking of the rotating pipeline 354 and the main negative-pressure pipeline 32, and enable the staff to adjust the rotation angle less when connecting the rotating pipeline 354 and the main negative-pressure pipeline 32, reduce the operation difficulty, and improve the simplicity and efficiency of the operation. A chamfer 3561 is arranged on the side of the locking block 356 away from the limiting block 357. On the one hand, the chamfer 3561 can guide the locking block 356 to be more easily inserted into the locking hole 3551 on the locking seat 355. On the other hand, the chamfer 3561 can apply a certain pre-tightening pressure to the connection between the rotating pipeline 354 and the main negative-pressure pipeline 32, and improve the sealing performance of the connection. A driving gear ring 358 is fixedly sleeved on the outer side of the rotating pipeline 354. A driving motor 359 is arranged on the quick-connect seat 351. A driving gear 3510 is fixedly sleeved on the output shaft of the driving motor 359. The driving gear 3510 meshes with the driving gear ring 358.

[0044] When the quick-connect component 35 is in the unconnected state, the rotating pipe 354 is separated from the main negative-pressure pipe 32, and the locking block 356 is not inserted into the locking hole 3551 of the locking seat 355. When connecting the rotating pipe 354 to the main negative-pressure pipe 32 through the quick-connect component 35, the staff first aligns the rotating pipe 354 with the main negative-pressure pipe 32, and then starts the driving cylinder 352 to push the telescopic pipe 353 to extend, so that the rotating pipe 354 approaches the main negative-pressure pipe 32. Subsequently, the driving motor 359 is started, and the driving gear 3510 rotates. Through meshing with the driving gear ring 358, the rotating pipe 354 is driven to rotate. During the rotation process, the locking block 356 aligns with the locking hole 3551 on the locking seat 355. When the locking block 356 is inserted into the locking hole 3551, the rotating pipe 354 and the main negative-pressure pipe 32 can achieve sealed docking. Among them, through the cooperation of the telescopic pipe 353 and the rotating pipe 354, the rapid connection between the main negative-pressure pipe 32 and the first vacuum pump device 33 is realized, greatly shortening the equipment preparation time. And under the cooperation of the locking block 356 and the locking seat 355, the sealing between the rotating pipe 354 and the main negative-pressure pipe 32 is ensured, avoiding negative-pressure leakage and improving the operation stability. At the same time, the telescopic pipe 353 can adapt to the connection requirements of different positions and angles, improving the adaptability and flexibility of the equipment.

[0045] Refer to Figure 6 and Figure 7 As shown in FIGS. and

[0045] , the shaping mechanism 4 includes a second vacuum pump device 41 disposed in the shaping area 12. A docking support 34 is also provided on the second vacuum pump device 41. A second electric control valve is further provided on the main negative-pressure pipe 32. A quick-connect component 35 is also provided between the docking support 34 on the second vacuum pump device 41 and the main negative-pressure pipe 32.

[0046] The second vacuum pump device 41 is used to perform pressure-holding treatment on the profiles in the forming device 2 in the shaping area 12. The power requirement of the second vacuum pump device 41 is much smaller than that of the first vacuum pump device 33. Therefore, on the premise of meeting the pressure-holding requirements of the shaping area 12, selecting a vacuum pump device with less power can effectively reduce the equipment purchase cost and operation cost. And the pressure-holding treatment in the shaping area 12 usually requires more precise negative-pressure control, and a vacuum pump device with less power can provide more accurate negative-pressure regulation. At the same time, a docking support 34 is also provided on the second vacuum pump device 41, and it is also connected to the main negative-pressure pipe 32 by a quick-connect component 35, so as to ensure the rapid and sealed connection between the second vacuum pump device 41 and the main negative-pressure pipe 32, improving the response speed and operation efficiency of the equipment.

[0047] The implementation principle of the multifunctional radio frequency vacuum integrated machine for door, wall cabinet processing in the embodiment of the present application is as follows: Radio frequency heating has universality and can be used to heat various types of wooden boards. The combination of the uniform heating and rapid heating characteristics of radio frequency heating and the precise control of vacuum technology can significantly improve the processing efficiency of profiles, reduce the processing cycle, and enhance the overall quality, stability, and finished product rate of profiles during processing. At the same time, multiple shaping chambers 121 are arranged along the height direction in the shaping area 12, which can simultaneously carry out pressure maintaining and shaping on the profiled materials after shaping in multiple shaping bins 21, improving the space utilization rate of the workshop and further enhancing the processing efficiency.

[0048] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
