Description

Technical Field

[0001] This invention relates to the field of flooring molding technology, specifically to a flooring hot pressing molding apparatus. Background Technology

[0002] In the current flooring manufacturing industry, the hot pressing process is a core step that determines the final quality and physical properties of the product. Traditional hot pressing equipment often faces technical bottlenecks when processing multi-layer composite flooring or special surface materials, such as uneven heat conduction, poor air venting, and internal stress generated during the cooling and shaping stage.

[0003] In existing technologies, most hot pressing devices rely on simple mechanical pressurization and electric heating tubes. This method can easily lead to bubbles, white spots, or warping deformation on the surface of the board due to uneven cooling. In addition, traditional molds have a large suction force during demolding, which not only increases mechanical energy consumption but also easily damages the edges of the board. Summary of the Invention

[0004] To address the aforementioned issues and overcome the defects in existing technologies where boards are prone to bubbles, white spots, or warping due to uneven cooling during hot pressing, this invention provides a flooring hot pressing device. By employing a high-frequency induction heating coil combined with a magnetically conductive frame, when an alternating magnetic field excites eddy currents within the hot pressing plate, rapid and uniform internal heat generation is achieved, significantly improving the thermal response speed and temperature field uniformity. Simultaneously, the same magnetic field excites a magnetostrictive rod to generate high-frequency micro-vibrations, which are directly transmitted to the board surface through the magnetically conductive block. This not only assists in the flow and wetting of the adhesive layer at high temperatures but also effectively breaks down the internal bubble structure of the board, promoting the expulsion of volatiles. This solves the problem of poor air venting caused by excessively rapid adhesive curing during traditional hot pressing, significantly improving the density and interlayer bonding strength of the flooring.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a floor hot-press forming device, comprising a fixed base, support columns, and a mounting top. Support columns are fixedly arranged around the top of the fixed base, and the top ends of the four support columns are fixedly connected to the bottom of the mounting top. Hydraulic cylinders are fixedly arranged in the middle of the top of both the fixed base and the mounting top. Hot-pressing components are movably arranged on opposite sides of the fixed base and the mounting top. One side of each of the two hot-pressing components is fixedly connected to the drive ends of the two hydraulic cylinders. The lower hot-pressing components are surrounded by sheet positioning parts for hot-press positioning of the sheet material to be processed, eliminating the need for manual sheet positioning.

[0006] Furthermore, the hot pressing assembly includes a hot pressing control frame and a hot pressing plate. The drive ends of the two hydraulic cylinders are each fixedly equipped with a movable frame, and the opposite sides of the two movable frames are each fixedly equipped with a connecting frame by bolts. The opposite sides of the two connecting frames are each fixedly equipped with a hot pressing control frame, and the opposite sides of the two hot pressing control frames are each fixedly equipped with a hot pressing plate. The opposite sides of the two hot pressing plates are each provided with a number of auxiliary microholes, and the hot pressing plates are made of magnetic alloy steel.

[0007] Furthermore, the hot-press control frame is internally fixed with several magnetic skeletons, and each magnetic skeleton has several mounting holes evenly distributed at an angle. Magnetic blocks are fixed above and below each mounting hole, and a magnetostrictive rod is slidably disposed between two magnetic blocks. A magnetic yoke groove is also provided in the middle of the outer circumference of each magnetic skeleton, and a high-frequency induction heating coil is sleeved inside the magnetic yoke groove.

[0008] Furthermore, the hot press plate has several cooling channels on its upper part, and each cooling channel is spirally arranged. Adjacent cooling channels are interconnected. The hot press plate has a cooling circulation interface and a cooling circulation outlet on its two sides, and the interiors of the cooling circulation interface and the cooling circulation outlet are connected to the interiors of the cooling channels.

[0009] Furthermore, the hot press plate has several auxiliary microholes inside, and a conveying channel is provided in the middle of the hot press plate. The inside of the conveying channel is connected to the inside of several auxiliary microholes. A microhole conveying interface is provided on one side of the hot press plate, and the inside of the microhole conveying interface is connected to the inside of the conveying channel.

[0010] Furthermore, the mounting top seat has adjustable sliding rods slidably arranged around its interior, and the bottom ends of the four adjustable sliding rods are fixedly connected to the top of the movable frame located above; the top of the fixed base has fixed posts fixedly arranged around its interior, and the four fixed posts have movable shafts slidably arranged inside, and the top ends of the four movable shafts are fixedly connected to the bottom of the movable frame located below.

[0011] Furthermore, the plate positioning part includes a positioning mounting frame and a positioning plate. Fixed frames are fixedly provided around the bottom of the movable frame, and an adjusting servo cylinder is fixedly provided inside the fixed frame. A rotary servo motor is fixedly provided at the drive end of the adjusting servo cylinder, and a rotating frame is fixedly provided at one end of the output shaft of the rotary servo motor. A positioning mounting frame is fixedly provided on one side of the top of the rotating frame by bolts.

[0012] Furthermore, the positioning mounting bracket has an adjustment slot inside, and servo linear slides are fixedly installed on both sides inside the adjustment slot. Several adjustment sliders are slidably installed between the surfaces of the two servo linear slides. A positioning servo electric cylinder is fixed inside each adjustment slider by bolts, and a positioning plate is movably inserted into the drive end of each positioning servo electric cylinder.

[0013] Furthermore, each positioning servo electric cylinder has a magnetic connecting block fixedly installed at its drive end, and each positioning plate has a magnetic connecting sleeve fixedly installed on one side. The inside of the magnetic connecting sleeve is magnetically attracted to one side of the magnetic connecting block.

[0014] The beneficial effects achieved by the present invention using the above structure are as follows: 1. This invention employs a structure combining a high-frequency induction heating coil with a magnetic skeleton. When the alternating magnetic field excites eddy currents inside the hot press plate, it achieves rapid and uniform internal heat generation, greatly improving the thermal response speed and temperature field uniformity. Simultaneously, the same magnetic field excites the magnetostrictive rod to generate high-frequency micro-vibrations. These vibrations are directly transmitted to the surface of the board through the magnetic block and the hot press plate. This not only assists in the flow and wetting of the adhesive layer at high temperatures but also effectively breaks the bubble structure inside the board, promoting the discharge of volatiles. This solves the problem of poor air venting caused by excessively rapid curing of the adhesive layer in traditional hot pressing processes, significantly improving the density and interlayer bonding strength of the flooring.

[0015] 2. During the hot pressing stage of the sheet material, a vacuum pump is connected through a microporous delivery interface to extract moisture and volatiles from the surface of the sheet material using negative pressure. Compared with the traditional simple vacuuming, this application utilizes Bernoulli's principle in fluid mechanics to form an extremely thin air cushion layer on the surface of the sheet material. This air cushion layer not only prevents the auxiliary micropores from being directly and tightly adsorbed to the surface of the sheet material, avoiding surface defects caused by excessive adsorption, but also ensures that volatiles can be continuously and stably extracted, effectively preventing appearance defects such as white spots or bubbles from appearing on the product surface. During the cooling stage, the auxiliary micropores are used for cooling gas delivery to further assist demolding and eliminate thermal inertia.

[0016] 3. By using the rotating frame to flip and avoid obstacles and the height adjustment of the servo electric cylinder, the rapid and precise positioning and clamping of boards of different thicknesses and specifications are achieved, so that the boards can be automatically corrected to the center position before hot pressing. At the same time, the synchronous hydraulic drive of the upper and lower hot pressing components, combined with the spiral cooling channel, ensures the parallelism of the pressure application and the uniformity of the cooling process, effectively eliminating the internal stress of the product during the cooling and shaping stage, preventing warping and deformation, and greatly improving the dimensional stability and processing efficiency of the finished flooring.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] Example 1

[0022] Please see Figures 1 to 7As shown, a flooring hot pressing forming device includes: a fixed base 1, support columns 2, and a mounting top 3. Support columns 2 are fixedly installed around the top of the fixed base 1, and the top ends of the four support columns 2 are fixedly connected to the bottom of the mounting top 3. Hydraulic cylinders 4 are fixedly installed in the middle of the top of both the fixed base 1 and the mounting top 3, and hot pressing components are movably installed on opposite sides of both the fixed base 1 and the mounting top 3. One side of each of the two hot pressing components is fixedly connected to the drive end of one of the two hydraulic cylinders 4. The lower hot pressing components are provided with plate positioning parts 9 around their perimeter for hot pressing positioning of the plates to be processed, eliminating the need for manual plate positioning. This improves the processing efficiency of flooring hot pressing forming and ensures the safety of the flooring hot pressing forming process.

[0023] It should be noted that by placing the board to be processed on top of the lower hot pressing component, and using the board positioning parts 9 around the perimeter to position the board to be processed, the upper hot pressing component is moved downward by the driving end of the hydraulic cylinder 4 at the top of the mounting base 3, while the lower hot pressing component is moved upward by the driving end of the hydraulic cylinder 4 at the top of the fixed base 1. The positioning board is hot-pressed and formed by the two hot pressing components. The hot pressing of the upper and lower boards by the two hot pressing components greatly improves the efficiency of hot pressing and forming of the floor.

[0024] Furthermore, the hot pressing assembly includes a hot pressing control frame 7 and a hot pressing plate 8. The drive ends of the two hydraulic cylinders 4 are each fixedly equipped with a movable frame 5, and the opposite sides of the two movable frames 5 are each fixedly equipped with a connecting frame 6 by bolts. The opposite sides of the two connecting frames 6 are each fixedly equipped with a hot pressing control frame 7, and the opposite sides of the two hot pressing control frames 7 are each fixedly equipped with a hot pressing plate 8. The opposite sides of the two hot pressing plates 8 are each provided with a number of auxiliary microholes 25, and the hot pressing plate 8 is made of magnetic alloy steel, serving as the hot pressing working surface and the load for electromagnetic induction.

[0025] Furthermore, the hot press control frame 7 is internally fixed with several magnetic skeletons 28, and each magnetic skeleton 28 is internally provided with several mounting holes 30 evenly distributed at angles. Each mounting hole 30 is internally fixed with magnetic blocks 31 at the top and bottom, and a magnetostrictive rod 32 is slidably provided between two magnetic blocks 31. Each magnetic skeleton 28 is also provided with a magnetic yoke groove in the middle of its outer peripheral surface, and a high-frequency induction heating coil 29 is sleeved inside the magnetic yoke groove.

[0026] Furthermore, the upper part of the hot press plate 8 is provided with several cooling channels 27, and the interior of each cooling channel 27 is arranged in a spiral shape. The interiors of adjacent cooling channels 27 are interconnected. Cooling circulation inlets and cooling circulation outlets are provided on both sides of the hot press plate 8, and the interiors of the cooling circulation inlets and cooling circulation outlets are connected to the interiors of the cooling channels 27. The cooling medium circulates within the cooling channels 27 through the cooling circulation inlets and cooling circulation outlets, which plays a role in uniformly heating the floor during the hot pressing process and avoids local overheating of the floor during the hot pressing process, thus affecting the hot pressing effect. In addition, after the floor is hot-pressed, the cooling medium can quickly cool the hot-pressed floor, effectively eliminating thermal inertia.

[0027] Furthermore, the hot press plate 8 has several auxiliary micropores 25 inside, and a conveying channel 26 is also provided in the middle of the hot press plate 8. The inside of the conveying channel 26 is connected to the inside of the several auxiliary micropores 25. A micropore conveying interface is provided on one side of the hot press plate 8, and the inside of the micropore conveying interface is connected to the inside of the conveying channel 26. A vacuum pump is connected to the micropore conveying interface. When the floor is hot-pressed, the hot press plate 8 comes into contact with the surface of the floor and is hot-pressed. In the early stage of hot pressing, the several auxiliary micropores 25 on one side of the hot press plate 8 are used to suck up the moisture and volatiles on the surface of the board, completely eliminating bubbles and white spots. In the later stage of hot pressing, cooling gas is sent into the inside of the several auxiliary micropores 25 through the micropore conveying interface in conjunction with the conveying channel 26 to assist the demolding operation between the hot press plate 8 and the hot-pressed board.

[0028] Furthermore, adjusting slide rods 10 are slidably provided around the inside of the mounting top 3, and the bottom ends of the four adjusting slide rods 10 are fixedly connected to the top of the upper movable frame 5; fixing columns 11 are fixedly provided around the top of the fixed base 1, and movable shafts 12 are slidably provided inside the four fixing columns 11, and the top ends of the four movable shafts 12 are fixedly connected to the bottom of the lower movable frame 5; the stability of the upper and lower movable frames 5 during the up and down movement is ensured by adjusting the slide rods 10 and the movable shafts 12.

[0029] Specifically, when the vacuum pump is started, gas is drawn at high speed from the surface of the board into the auxiliary micropores 25. According to Bernoulli's principle, the higher the fluid velocity, the lower the static pressure. At the inlet of the auxiliary micropores 25, the high-speed flowing gas forms a low-pressure zone. However, this low-pressure zone is dynamic, as it attracts surrounding gas to continuously replenish it. The high-speed airflow forms an air cushion layer in the tiny gaps between the auxiliary micropores 25 and the surface of the board. This air cushion layer, like the air layer at the bottom of a hovercraft, separates the edge of the auxiliary micropores 25 from the surface of the board, preventing direct physical contact and adsorption. A dynamic balance is reached between the airflow intake rate, the release rate of volatiles on the surface of the board, and the leakage airflow rate through the surface roughness gaps. This balance ensures that the airflow can continuously carry away moisture and volatiles without forming excessively strong adsorption forces in certain areas.

[0030] In addition, the process of extracting moisture and volatiles through the auxiliary micropores 25 mainly occurs in the early and middle stages of hot pressing. At this time, the board is not yet fully cured, and its surface state is conducive to avoiding adsorption. In the early stage of hot pressing, the board temperature is low, the adhesive and moisture are in an unactivated or semi-activated state, and the board surface is relatively dry and loose. The auxiliary micropores 25 mainly extract free water and a small amount of volatiles diffused from the inside of the board to the surface. At this time, no adhesion has been formed between the board surface and the hot press plate, and the airflow effect of the auxiliary micropores 25 is mainly suction. In the middle stage of hot pressing, as the temperature rises, As the adhesive begins to melt and flow, the auxiliary micropores 25 primarily extract the solvent, small molecule gases produced by the curing reaction, and residual moisture from the adhesive. Because the adhesive is in a molten and flowing state, its viscosity is low and its fluidity is good, allowing it to quickly fill the micro-pits on the surface of the board, as well as the tiny gaps between the edges of the auxiliary micropores 25 and the surface of the board. In the later stages, the board has basically cured, the adhesive has hardened, and a strong bond has been formed between the board and the surface of the hot press plate. At this point, the main function of the auxiliary micropores 25 has changed from extracting volatiles to introducing cooling gas, and vacuum extraction is no longer performed.

[0031] It should be noted that a stable frame is formed by the fixed base 1, support column 2, and mounting top 3. The hydraulic cylinders 4 on the fixed base 1 and mounting top 3 synchronously drive the upper and lower movable frames 5, connecting frame 6, and hot press control frame 7, thereby driving the hot press plate 8 to apply bidirectional pressure to the sheet material. The sheet material positioning part 9 automatically clamps the edge of the sheet material before pressure is applied to ensure accurate positioning. The hot press plate 8 is made of magnetic alloy steel. When the high-frequency induction heating coil 29 inside is energized, it generates an alternating magnetic field. This magnetic field is efficiently coupled to the hot press plate 8 through the closed magnetic circuit formed by the magnetic skeleton 28, inducing eddy currents inside the magnetic alloy steel of the hot press plate 8. The eddy currents overcome the material resistance to generate Joule heat and achieve rapid heating. At the same time, the alternating magnetic field acts on the magnetostrictive rod 32 that is slidably set inside the magnetic skeleton 28. This stimulates the magnetostrictive effect, generating micron-level high-frequency axial stretching vibrations. These vibrations are transmitted to the surface of the board through the magnetic block 31 and the hot press plate 8, forming an ultrasonic-assisted effect during the hot pressing process. This gives the adhesive layer better fluidity at high temperatures, promotes the expulsion of air bubbles within the adhesive layer, and improves the bonding strength and surface texture replication accuracy. The spiral cooling channel 27 inside the hot press plate 8 is connected to the outlet through a circulation interface, introducing a cooling medium to achieve uniform heating and rapid cooling. The auxiliary micropores 25 on the surface of the hot press plate 8 are connected to the micropore conveying interface through the conveying channel 26. In the early stage of hot pressing, a suction pump is connected to extract moisture and volatiles from the surface of the board. In the later stage of hot pressing, cooling gas is introduced to assist demolding, thereby realizing fully automated control of the entire process of heating, pressurizing, venting, cooling, and demolding.

[0032] The bidirectional synchronous pressurization combined with the board positioning unit 9 achieves automated positioning and processing without manual intervention, significantly improving production efficiency and ensuring operational safety. The synergistic effect of high-frequency induction heating and magnetostrictive vibration not only accelerates the heating rate but also effectively eliminates air bubbles in the adhesive layer through micro-vibration, improving bonding strength and surface texture replication. The spiral cooling channel 27 achieves uniform temperature distribution and rapid cooling, avoiding board deformation or performance degradation caused by local overheating. The vacuum suction and gas delivery system composed of auxiliary micropores 25 and conveying channel 26 thoroughly removes moisture and volatiles in the early stage of hot pressing, eliminating air bubbles and white spot defects. The injection of cooling gas in the later stage of hot pressing effectively assists demolding, preventing board adhesion or surface damage. The entire device has a compact structure and high functional integration, significantly improving the yield rate of flooring products and the level of production automation.

[0033] Example 2

[0034] Specifically, the plate positioning part 9 includes a positioning mounting bracket 17 and a positioning plate 24. The bottom of the movable frame 5 is fixedly equipped with a fixed bracket 13 on all four sides, and an adjusting servo cylinder 14 is fixedly installed inside the fixed bracket 13. A rotary servo motor 15 is fixedly installed at the drive end of the adjusting servo cylinder 14, and a rotating frame 16 is fixedly installed at one end of the output shaft of the rotary servo motor 15. The positioning mounting bracket 17 is fixedly installed on one side of the top of the rotating frame 16 by bolts. The positioning mounting bracket 17 is provided with an adjusting through groove 18 inside, and a servo linear slide 19 is fixedly installed on both sides inside the adjusting through groove 18. Several adjusting sliders 20 are slidably arranged between the surfaces of the two servo linear slides 19. A positioning servo cylinder 21 is fixedly installed inside each adjusting slider 20 by bolts, and a positioning plate 24 is movably inserted into the drive end of each positioning servo cylinder 21.

[0035] Furthermore, each positioning servo electric cylinder 21 has a magnetic connecting block 22 fixedly installed at its drive end, and each positioning plate 24 has a magnetic connecting sleeve 23 fixedly installed on one side. The interior of the magnetic connecting sleeve 23 is magnetically attracted to one side of the magnetic connecting block 22. The magnetic connecting block 22 adopts a regular octagonal prism structure design, and the interior of the magnetic connecting sleeve 23 has an inner octagonal groove that matches the magnetic connecting block 22. One side of the magnetic connecting block 22 is covered with a metal sheet, and the interior of the magnetic connecting sleeve 23 has a magnet. By fitting the interior of the magnetic connecting sleeve 23 onto one end of the magnetic connecting block 22, the magnetic attraction connection between the positioning plate 24 and the drive end of the positioning servo electric cylinder 21 is achieved.

[0036] It should be noted that during the feeding operation of the sheet material, the drive end of the rotary servo motor 15 controls the rotating frame 16 to flip to one side, so that the hot press plate 8 below is unobstructed on all sides, making it easy to place the sheet material on top of the hot press plate 8. Then, the output shaft of the rotary servo motor 15 controls the rotating frame 16 to flip and reset. According to the number of hot press sheet materials, the corresponding number of positioning servo cylinders 21 are installed inside the adjusting slider 20, and the positioning plate 24 is installed on the drive end of the positioning servo cylinder 21. The drive end of the adjusting servo cylinder 14, in conjunction with the rotating frame 16, controls the positioning mounting frame 17 to move to one side of the hot press plate 8. According to the height of multiple sheet materials, the servo linear slide 19 drives the adjusting slider 20 to slide up and down inside the adjusting groove 18. The drive end of the positioning servo cylinder 21 controls the positioning plate 24 to fit against the outer peripheral surface of the sheet material. The positioning plates 24 on all sides are used to correct the position of the sheet material above the hot press plate 8, so that the sheet material to be hot-pressed can be quickly positioned to the accurate position for hot pressing.

[0037] Specifically, the fixed frame 13 is installed around the bottom of the movable frame 5. The servo electric cylinder 14 drives the rotary servo motor 15 and the rotating frame 16 to achieve the overall lifting and flipping of the positioning component, so as to avoid the working space of the hot press plate 8 below when loading. After the rotating frame 16 is reset, the positioning mounting frame 17 slides up and down in the adjusting groove 18 through the servo linear slide table 19 to adapt to the height requirements of different thickness plates. Several adjusting sliders 20 are distributed along the servo linear slide table 19. Each slider is equipped with a positioning servo electric cylinder 21. Its driving end is magnetically attracted to the magnetic connecting sleeve 23 on the positioning plate 24 through the magnetic connecting block 22. During operation, the position of the adjusting slider 20 is flexibly adjusted according to the size and quantity of the plate to be processed, and the corresponding number of positioning servo electric cylinders 21 and positioning plates 24 are loaded. The extension and retraction action of the positioning servo electric cylinder 21 pushes the positioning plate 24 to fit tightly against the outer peripheral surface of the plate, thereby completing the automatic position correction and clamping positioning of the plate.

[0038] By adjusting the coordination between the servo electric cylinder 14 and the rotary servo motor 15, the automatic flipping and avoidance of the positioning component is realized, which greatly facilitates the loading operation of the sheet metal and eliminates the interference risk during manual handling. The combination of the servo linear slide 19 and the adjusting slider 20 allows for precise adjustment of the positioning height. With the flexible addition and reduction of the number of positioning servo electric cylinders 21 and positioning plates 24, it can adapt to the positioning needs of sheet metal of various sizes, thicknesses and quantities, greatly enhancing the flexible production capacity of the equipment. The octagonal prism and inner octagonal groove matching structure of the magnetic connecting block 22 and the magnetic connecting sleeve 23 not only ensures the stability and coaxiality of the positioning plate 24 connection, but also realizes quick disassembly and assembly, which facilitates the quick replacement of positioning plates 24 of different specifications according to production tasks, effectively shortening the changeover time and improving production efficiency and positioning accuracy.

[0039] Example 3

[0040] Specifically, this embodiment discloses a working method of a floor hot pressing forming device, including the following steps: Step 1: Activate the avoidance mode for the plate positioning part 9 around the hot press assembly located below. Adjust the servo cylinder 14 to drive the rotary servo motor 15 to rotate the rotating frame 16 outward, so that the positioning mounting frame 17 and positioning plate 24 are moved away, making room for the hot press plate 8 below to be placed without obstruction. The operator or automatic feeding robot lays the plate to be processed flat in the center area of ​​the hot press plate 8 below. Step 2: The rotary servo motor 15 rotates in the opposite direction, driving the rotating frame 16 and the positioning mounting frame 17 to return to the top of the hot press plate 8. The servo electric cylinder 14 adjusts the height of the positioning mounting frame 17 according to the thickness of the plate. The servo linear slide 19 drives the adjusting slider 20 to slide along the adjusting groove 18, so that the height of the positioning servo electric cylinder 21 and the positioning plate 24 are aligned with the side of the plate. The positioning servo electric cylinder 21 extends out of the drive end and drives the positioning plate 24 to move inward through the magnetic connection block 22 and the magnetic connection sleeve 23 until the four positioning plates 24 are tightly attached to the outer circumference of the plate, thus completing the precise position correction of the plate. Step 3: The hydraulic cylinder 4 at the top of the mounting base 3 drives the upper hot pressing component to move downwards, while the hydraulic cylinder 4 at the top of the fixed base 1 drives the lower hot pressing component to move upwards. The upper and lower hot pressing plates 8 apply a preset pressure to the plate simultaneously. During this process, the high-frequency induction heating coil 29 is energized to generate an alternating magnetic field, which is coupled to the inside of the hot pressing plate 8 through the magnetic guide frame 28 to generate eddy currents and achieve rapid heating. At the same time, the magnetic field excites the magnetostrictive rod 32 to generate high-frequency micro-vibration. The vibration is transmitted to the surface of the plate through the magnetic guide block 31 to assist the flow of the adhesive layer and the exhaust. Meanwhile, the micro-hole delivery interface is connected to a vacuum pump, and the moisture and volatiles on the surface of the plate are sucked out through the delivery channel 26 using the auxiliary micro-holes 25. The air cushion layer formed by Bernoulli's principle prevents the auxiliary micro-holes 25 from being directly adsorbed to the surface of the plate, ensuring that the volatiles are continuously extracted without producing bubbles or white spots. Step 4: When the hot pressing time reaches the set value and the internal temperature of the board reaches the process requirements, the high-frequency induction heating coil 29 stops heating, the micro-hole conveying interface switches to the cooling gas conveying mode, and cooling gas is introduced into the auxiliary micro-hole 25 to assist demolding. At the same time, the cooling medium enters the spiral cooling channel 27 through the cooling circulation interface and circulates, quickly removing the heat from the hot press plate 8 and the board, eliminating thermal inertia and preventing the board from deforming. Step 5: After the temperature of the board material drops to a safe range, the upper and lower hydraulic cylinders 4 drive the hot pressing components to separate, the positioning servo cylinder 21 retracts and drives the positioning plate 24 to detach from the surface of the board material, the adjusting servo cylinder 14 drives the rotating frame 16 to flip and avoid it, and the operator or robot arm takes out the finished flooring after hot pressing. All parts of the device are reset and ready for the next cycle of processing.
