Description

Technical Field

[0001] This invention belongs to the technical field of wood board hot pressing devices, and particularly relates to a hot pressing and gluing device for wood board film coating, which is mainly used for coating plastic film or decorative paper on the surface of wood boards, especially for situations where one end of the wood board needs to be shaped. Background Technology

[0002] After the wood boards are cut and processed to the required size, a layer of plastic film is usually covered on the surface of the wood boards to improve their waterproof, stain-resistant, and wear-resistant properties, as well as to increase the aesthetic appeal of the wood boards.

[0003] Currently, the industrial method for laminating wood panels involves applying glue to the wood panel or a thin film, then covering the wood panel with the film, and finally using a hot-pressing process (i.e., heated extrusion) to firmly bond the film to the wood panel. However, with the diversification of market demands, irregularly shaped wood panels with rounded, V-shaped, or other irregular shapes have emerged. When laminating these irregularly shaped wood panels, the traditional hot-pressing lamination method reveals significant drawbacks: air can easily remain between the film and the wood panel during the hot-pressing process, leading to problems such as bubbles, bulges, and uneven surfaces after lamination, seriously affecting product quality.

[0004] To address the issue of air residue, some automated wood panel wrapping machines have emerged in the existing technology. While these machines can achieve a good tight bond between the film and the wood panel, they are generally expensive to manufacture, use, and maintain. This makes them unaffordable for small and medium-sized enterprises with limited funds and poor applicability.

[0005] Therefore, developing a low-cost, easy-to-operate, and high-performance wood board coating device to meet the production needs of small and medium-sized enterprises has become an urgent technical problem to be solved in the current wood processing equipment field. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned technical problems by providing a hot-press gluing device for wood board lamination. This hot-press gluing device has a reasonable structural design, low cost, and can effectively solve the problem of air residue when laminating irregularly shaped wood boards. It ensures that the film and wood board are tightly bonded after lamination, with a smooth surface free of bubbles. It is also easy to operate and suitable for small-scale enterprises.

[0007] In view of this, the present invention provides a hot-pressing bonding apparatus for wood panel lamination, comprising: The frame has a platform on it for placing wooden planks; The end shaping mechanism includes a hot pressing roller and a flat pusher, which are respectively arranged on both sides of the platform. The hot pressing roller can be heated, and the side of the hot pressing roller near the flat pusher has a shaping groove that matches the irregular end shape of the wooden board. The flat pusher can push the wooden board toward the hot pressing roller. The extrusion conveying mechanism includes two extrusion rollers and a rotary drive. The two extrusion rollers are rotatably mounted on the frame and can rotate under the drive of the rotary drive. The two extrusion rollers have a gap adapted to the thickness of the wooden board, so that the air between the film and the wooden board can be extruded from one end of the wooden board to the other end during the rotation of the two extrusion rollers and the movement of the wooden board. The two-sided shaping mechanism includes two hot press plates and a longitudinal pusher. The two hot press plates can move closer or further apart under the drive of the longitudinal pusher, and both hot press plates can be heated.

[0008] In the above technical solution, the hot press roller is further provided with mounting holes, in which heating elements can be installed, and the heating elements can heat the surface of the hot press roller.

[0009] In the above technical solution, the hot press plate is further provided with an installation groove, a limiting member in the installation groove, and the heating element can be installed in the installation groove through the limiting member, and the heating element can heat the surface of the hot press plate.

[0010] In the above technical solution, one hot press plate is a fixed hot press plate that is fixedly connected to the frame, and the other hot press plate is a movable hot press plate that can approach or move away from the fixed hot press plate. The longitudinal pusher is set on the frame, and the output end of the longitudinal pusher is connected to the movable hot press plate.

[0011] In the above technical solution, the longitudinal thrust component further includes multiple sets of longitudinal thrust cylinders, which are distributed at intervals along the direction perpendicular to the movement of the movable hot press plate, and the piston rod on each set of longitudinal thrust cylinders is connected to the movable hot press plate.

[0012] In the above technical solution, the two extrusion rollers are further distributed at intervals in the moving direction of the movable hot press plate. One extrusion roller is rotatably mounted on the side wall of the fixed hot press plate, and the other extrusion roller is rotatably mounted on the side wall of the movable hot press plate. The distance between the two hot press plates is the same as the distance between the two extrusion rollers.

[0013] In the above technical solution, the rotary drive component further includes two sets of drive sources, which drive the two extrusion rollers to rotate respectively.

[0014] In the above technical solution, the extrusion conveying mechanism further includes two sets of mounting frames. The two extrusion rollers are respectively mounted on the side walls of the two hot press plates through the two sets of mounting frames. Multiple sets of auxiliary support members are arranged at intervals along the length direction of the extrusion rollers on the mounting frames. Each set of auxiliary support members includes a support frame and two guide wheels. The two guide wheels are rotatably mounted on the mounting frame through the support frame. The two guide wheels are located on both sides of the extrusion rollers, and both guide wheels are in contact with the outer circular surface of the extrusion rollers.

[0015] In the above technical solution, the extrusion conveying mechanism is located above the hot press roller, one side surface of the hot press roller abuts against the bottom surface of a set of mounting frames, and a clamping member is provided on the side of the hot press roller away from the mounting frame, which can press or release the hot press roller against the bottom surface of the mounting frame.

[0016] This invention also discloses a method of using the aforementioned hot-press bonding apparatus, the method comprising the following steps: S1. Preliminary gluing: Apply glue to the surface of the wood board or the film, and cover the three continuous surfaces of the wood board, including the irregular ends, with the film to obtain a preliminarily glued wood board. S2, End Shaping: Manually place the pre-glued wooden board on the platform between the hot press roller and the flat pusher, with the irregular end of the board facing the shaping groove on the hot press roller. Then control the flat pusher to push the pre-glued wooden board towards the hot press roller, so that the irregular end of the board, along with the film, enters the shaping groove. Then heat the hot press roller and hot press for a certain time to obtain the end-shaped wooden board. Finally, control the flat pusher to move away from the wooden board. S3, Exhaust by Extrusion: Start the two sets of drive sources to drive the two extrusion rollers to rotate. Manually raise the end-shaped wooden board to the same height as the extrusion conveying mechanism, and then push the shaped end of the wooden board into the space between the two extrusion rollers. This allows the wooden board and film to be conveyed to the space between the fixed hot press plate and the movable hot press plate. During this process, the two extrusion rollers press the film tightly onto the two opposite surfaces of the wooden board, and expel the air between the film and the wooden board from the irregular end of the wooden board to the other end. During this process, it is necessary to manually support the end of the wooden board away from the extrusion rollers. After the wooden board separates from the two extrusion rollers, it is necessary to manually push the wooden board completely into the space between the fixed hot press plate and the movable hot press plate. S4. Two-sided shaping: After the wood board is fully inserted into the space between the fixed hot press plate and the movable hot press plate, the longitudinal pusher is controlled to drive the movable hot press plate to press closer to the wood board, so that the movable hot press plate and the fixed hot press plate cooperate to press the two surfaces of the film and the wood board tightly. Then the two hot press plates are heated and hot-pressed for a period of time to obtain a wood board with both ends and both sides shaped. Finally, the longitudinal pusher is controlled to drive the movable hot press plate away from the wood board. S5. Material cutting: Manually remove the wood boards with the ends and both sides shaped from the fixed hot press plate to complete the hot press bonding of the wood board film.

[0017] The beneficial effects of this invention are: 1. By using a shaping groove in the end shaping mechanism that is compatible with the irregular ends (arc, V-shape, etc.) of the wood board and a heatable hot press roller, the irregular ends of the wood board are precisely hot-pressed and shaped. Combined with the extrusion conveying mechanism and the directional exhaust design from the irregular end of the wood board to the other end, the problems of bubbles, bulges, and uneven surfaces that are easy to occur after lamination of wood boards with irregular ends in traditional lamination methods are solved. This ensures that the film is tightly bonded to the surface of the wood board with irregular ends, and greatly improves product quality.

[0018] 2. The end-forming mechanism, extrusion conveying mechanism, and two-sided forming mechanism are compactly integrated on the frame, reducing the space occupied by the device. Furthermore, the wooden boards can be manually transferred between the three stations by workers, eliminating the need for transfer mechanisms between the three stations. This simplifies the overall structure of the device, reduces manufacturing costs, and consequently lowers the operating costs for the enterprise.

[0019] 3. Through the continuous process design of "end shaping → extrusion degassing → two-sided shaping", the equipment realizes integrated processing from initial gluing to final shaping, without the need for additional transfer or auxiliary equipment, which greatly improves the lamination efficiency. In addition, the equipment can be adapted to the processing of wood boards with different end shapes and thicknesses by changing the hot press rollers with different shaping groove shapes, extrusion roller spacing and hot press plate pressure / temperature. It is also compatible with a variety of wood lamination adhesives and plastic films, with strong versatility to meet diverse production needs. Attached Figure Description

[0032] 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.

[0033] In the description of this invention, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items, and therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0034] The wooden board B structure in this invention is as follows: Figure 1 As shown, Figure 1 The text illustrates the structure of three types of wooden boards B. Each type of wooden board B has a specific shape at one end, namely, an irregular end B1. From top to bottom, the irregular ends B1 of the three wooden boards B are arc-shaped, V-shaped, and irregular shapes formed by a combination of arc-shaped and V-shaped. These wood panels B are commonly used in this field as cabinet panels for various types of cabinets; Figure 2 A schematic diagram is shown showing the film M covering a wooden board B. During the film covering process, glue is first applied to the wooden board B or the film M, and then the film M is placed on the surface of the wooden board B that needs to be covered. In this invention, the three continuous surfaces of the wooden board B, including the irregular end B1, are taken as an example, namely the irregular end B1 of the wooden board B and the upper and lower surfaces of the wooden board B. The film M does not cover the end of the wooden board B that is away from the irregular end B1. After the film M is placed on the surface of the wooden board B that needs to be covered, the film M should still have some excess material beyond the wooden board B. After the hot pressing and gluing of this invention is completed, the excess film M needs to be cut off according to the actual situation. The main function of the hot-press bonding device of the present invention is to first hot-press the irregularly shaped end B1 of the film M and the wooden board B to shape it. After the irregularly shaped end B1 is shaped, as... Figure 2 As shown, the hot press gluing device squeezes the air between the wood board B and the film M from the irregular end B1 of the wood board B to the other end, and finally discharges it from the other end of the wood board B; after the air between the wood board B and the film M is discharged, the hot press gluing device then heat-presses the film M and the upper and lower surfaces of the wood board B to shape it, thus completing the three-sided covering of the wood board B. The specific structure and main connection relationships of the hot-press bonding device of the present invention are described below; Example 1 This embodiment provides a hot-press gluing device for wood panel lamination, including a frame 1, an end shaping mechanism, an extrusion conveying mechanism, and a two-sided shaping mechanism; Rack 1 The frame 1 serves as the installation foundation and support carrier for the entire device, providing a stable installation platform 2 for each component. The overall structure of the frame 1 must have sufficient strength and stability to ensure the reliability of the device during operation. Q235 steel can be selected as the main material.

[0035] Please see Figure 3 The frame 1 is equipped with a platform 2 for placing the wooden board B. The platform 2 provides a support surface for the initial placement and end shaping of the wooden board B. The surface of the platform 2 must be kept flat to avoid affecting the positioning and coating effect of the wooden board B due to unevenness. Platform 2 can be a flat surface, or it can be like... Figure 3 As shown, the surface formed by splicing multiple frame members is sufficient as long as it allows the wooden board B to be placed stably and to move horizontally.

[0036] End forming mechanism Please see Figure 4 In this embodiment, the end-shaping mechanism includes a hot-pressing roller 3 and a flat-push component 4. The hot-pressing roller 3 and the flat-push component 4 are respectively disposed on both sides of the platform 2, and are arranged opposite to each other to form a working space for clamping and shaping the irregular end B1 of the wooden board B. The hot-pressing roller 3 can be heated. For example, the hot-pressing roller 3 can be made of aluminum. Please refer to [link to relevant documentation]. Figures 4-6 The hot press roller 3 is a rectangular elongated structure. A mounting hole 302 is provided in the hot press roller 3, extending through at least one end of the hot press roller 3. A heating element 11 can be installed in the mounting hole 302, and the heating element 11 can heat each surface of the hot press roller 3. In this embodiment, the operating temperature of the hot press roller 3 is generally between 100℃ and 150℃. The heating element 11 can be a commercially available electric heating tube, such as a stainless steel electric heating tube with a power of 1kW. The hot press roller 3 has a shaping groove 301 on the side near the flat pusher 4 that is adapted to the shape of the end of the wooden board B. The shape of the shaping groove 301 can be designed according to the actual shape of the end of the irregular wooden board B, such as arc shape, V shape, etc., to ensure that it can fit completely with the irregular end B1 of the wooden board B.

[0037] The flat pusher 4 pushes the wooden board B towards the hot press roller 3, achieving precise alignment and pressing between the irregular end B1 of the wooden board B and the shaping groove 301 of the hot press roller 3. In this embodiment, the hot press roller 3 is fixedly mounted on the frame 1. The flat pusher 4 can be a combination of a cylinder and a pusher plate. The cylinder is an SC100×300 cylinder, mounted on the frame 1, with the piston rod of the cylinder horizontally facing the hot press roller 3. The pusher plate is mounted on the piston rod of the cylinder and can be made of steel plate. A rubber pad is adhered to the surface of the pusher plate that contacts the wooden board B, providing cushioning and preventing damage to the surface of the wooden board B. For this embodiment, please refer to [link to relevant documentation]. Figure 3Multiple sets of cylinders and push plates are spaced apart along the length of the wooden board B on the frame 1. After the wooden board B is placed between the push plate and the hot press roller 3, the multiple sets of cylinders are started at the same time, driving multiple push plates to push the wooden board B towards the hot press roller 3, so that the irregular end B1 of the wooden board B is subjected to more uniform force at each position during the shaping process.

[0038] Extrusion Conveyor The extrusion conveying mechanism includes two extrusion rollers 5 and a rotary drive (not shown in the figure). The two extrusion rollers 5 are rotatably mounted on the frame 1 and arranged in parallel with each other. The two extrusion rollers 5 can rotate synchronously in opposite directions under the drive of the rotary drive. There is a gap between the two extrusion rollers 5 that is adapted to the thickness of the wooden board B. In this way, when the two extrusion rollers 5 rotate and drive the wooden board B to move, they can squeeze out the air between the film M and the wooden board B from one end of the wooden board B to the other end. This gap is generally the same as the thickness of the wooden board B to avoid air residue and at the same time achieve the initial bonding between the film M and the surface of the wooden board B. In this embodiment, the extrusion roller 5 can be made of seamless steel pipe, and the extrusion conveying mechanism also includes two sets of mounting frames 8. The mounting frames 8 can be made of Q235 steel plate. The two sets of mounting frames 8 are mounted on the frame 1, and the two extrusion rollers 5 are rotatably mounted on the two sets of mounting frames 8 respectively. For example, bearing seats are provided on both sides of the mounting frame 8, and both ends of the extrusion roller 5 are connected to the two bearing seats through bearings to ensure that the two extrusion rollers 5 can rotate flexibly. In this embodiment, the rotary drive can be two sets of RV063 geared motors with a power of 0.75kW. The two sets of geared motors are respectively mounted on two sets of mounting brackets 8 through motor mounts. The output shafts of the two sets of geared motors are respectively connected to one end of the two extrusion rollers 5 through couplings. Synchronous drive is achieved through the electrical control system to ensure that the rotation speed of the two extrusion rollers 5 is consistent.

[0039] Two-sided shaping mechanism In this embodiment, the two-sided shaping mechanism includes two hot press plates and a longitudinal pusher 7. The two hot press plates can move closer to each other or further away from each other under the drive of the longitudinal pusher 7 to achieve pressing and hot pressing shaping of the upper and lower surfaces of the wood board B. Both hot press plates can be heated. Through the combined action of heating and pressing, the glue on the surface of the film M and the wood board B is fully cured, ensuring that the film M and the wood board B are tightly and firmly bonded. Please see Figures 3-6 A hot press plate is a fixed hot press plate 601 that is fixedly connected to the frame 1. The fixed hot press plate 601 is fixedly installed on the lower part of the frame 1 by bolts. The bolts are evenly distributed along the edge of the fixed hot press plate 601, and the upper surface of the fixed hot press plate 601 is kept horizontal. The other hot press plate is a movable hot press plate 602 that can approach or move away from the fixed hot press plate 601. The movable hot press plate 602 is located above the fixed hot press plate 601 and is arranged parallel to the fixed hot press plate 601. Guide sliders are provided on both sides of the movable hot press plate 602, and guide rails are correspondingly provided on the frame 1. The guide sliders slide in cooperation with the guide rails to ensure that the movable hot press plate 602 can move smoothly in the vertical direction. In this embodiment, the two hot press plates have the same structure and can both be made of aluminum. The two hot press plates are arranged symmetrically. Taking the movable hot press plate 602 as an example, please refer to [link to example]. Figure 9 and Figure 10 The bottom surface of the movable hot press plate 602 is flat, and the upper surface of the movable hot press plate 602 is provided with an installation groove 603. A limiting member 604 is provided in the installation groove 603. The limiting member 604 includes a limiting plate and a bolt. The bottom surface of the limiting plate is provided with a limiting groove that matches the contour of the heating element 11. The limiting groove and the bottom surface of the installation groove 603 form a space for the heating element 11 to be installed. After the heating element 11 is placed in the installation groove 603, the limiting plate is installed into the installation groove 603 so that the surface of the limiting groove presses against the outer wall of the heating element 11. The heating element 11 is pressed and fixed in the installation groove 603 by the cooperation of the limiting plate and the bolt, so that the heating element 11 is in close contact with the inner wall of the installation groove 603, thereby improving the heat conduction effect. The wiring terminal of the heating element 11 can be led out from the end of the hot press roller 3 and the hot press plate, and connected to the temperature control system through the wire to realize the automatic control of the heating temperature. The heating element in the installation groove can be a stainless steel electric heating tube with a power of 1.5kW. The longitudinal thrust member 7 is mounted on the frame 1, and its output end is connected to the movable hot press plate 602; in this embodiment, please refer to Figure 6 and Figure 7 The longitudinal pusher 7 includes multiple sets of longitudinal pusher cylinders, which are spaced apart along the direction perpendicular to the movement of the movable hot press plate 602. The multiple sets of longitudinal pusher cylinders are driven synchronously to ensure that the movable hot press plate 602 is subjected to uniform force during movement, avoiding tilting or deviation, and ensuring the parallelism between the movable hot press plate 602 and the fixed hot press plate 601. This ensures that the pressure on the upper and lower surfaces of the wooden board B is consistent, improving the quality of the two-sided film coating. The longitudinal pusher cylinder can be a hydraulic cylinder of model HSG100×200. The longitudinal pusher cylinder is fixed to the top of the frame 1 by a mounting plate, which is welded to the frame 1. The piston rod of the longitudinal pusher cylinder extends downward and is fixedly connected to the upper surface of the movable hot press plate 602 by a flange. A buffer pad is provided between the flange and the movable hot press plate 602 to reduce the impact on the movable hot press plate 602 when the longitudinal pusher 7 moves.

[0040] In this embodiment, the hot press plates are divided into a fixed hot press plate 601 and a movable hot press plate 602. The longitudinal pusher 7 drives the movable hot press plate 602 to move. This structural design simplifies the driving method of the two-sided shaping mechanism and reduces the manufacturing cost of the equipment. The fixed hot press plate 601 provides a stable support surface, and the movable hot press plate 602 achieves pressing and releasing actions under the drive of the longitudinal pusher 7, making operation simple. The moving direction of the movable hot press plate 602 is perpendicular to the fixed hot press plate 601, which can ensure the parallelism between the two hot press plates, ensure uniform pressure on the upper and lower surfaces of the wood board B, and make the film M adhere tightly to the wood board B, improving the uniformity and firmness of the coating. In addition, this structure makes it easy to adjust the spacing between the two hot press plates according to the different thicknesses of the wood board B, improving the versatility of the equipment.

[0041] Connection between the extrusion conveying mechanism and the two-sided shaping mechanism In this embodiment, please refer to Figure 5 and Figure 6 Two sets of mounting brackets 8 are respectively fixed to the side walls of the fixed hot press plate 601 and the movable hot press plate 602 by bolts. The mounting surface of the mounting bracket 8 is in close contact with the side wall of the hot press plate to ensure the verticality and flatness of the mounting bracket 8. Two extrusion rollers 5 are respectively located on the side walls of the fixed hot press plate 601 and the movable hot press plate 602 and are parallel to each other. The axis of the extrusion rollers 5 is consistent with the length direction of the hot press plate. In addition, the distance between the two hot press plates is the same as the distance between the two extrusion rollers 5. This structural design allows the extrusion conveying mechanism and the two-sided shaping mechanism to form a continuous working channel. After being conveyed by the extrusion roller 5, the wooden board B can directly enter between the two hot press plates for hot pressing and shaping, without the need for additional conveying devices, which simplifies the equipment structure and reduces manufacturing costs. Meanwhile, the linkage design between the extrusion rollers 5 and the hot press plates ensures that the spacing between the extrusion rollers 5 and the spacing between the hot press plates are adjusted synchronously, adapting to the processing of wood boards B of different thicknesses and improving the ease of operation of the equipment. The extrusion rollers 5 perform initial air venting and bonding during the conveying of wood board B, followed by final hot pressing and shaping by the hot press plates, allowing the laminating process to proceed continuously and improving production efficiency.

[0042] Connection between hot press roller 3 and extrusion conveyor mechanism Please see Figure 8 The extrusion conveying mechanism is located above the hot press roller 3. One side surface of the hot press roller 3 abuts against the bottom surface of a set of mounting frames 8. A clamping member 10 is provided on the side of the hot press roller 3 away from the mounting frame 8. The clamping member 10 is installed on the frame and located below the platform. The clamping member 10 can press or release the hot press roller 3 against the bottom surface of the mounting frame 8. In this embodiment, the clamping component 10 includes a bracket and a cylinder. The bracket is welded to the frame 1 and is located below the platform 2. The cylinder is mounted on the bracket. The hot press roller 3 is located between the cylinder and the mounting frame 8. The piston rod of the cylinder faces the hot press roller 3, and a pressure plate is installed at the end of the piston rod of the cylinder. When installing the hot press roller 3, the hot press roller 3 is first placed between the mounting frame 8 and the pressure plate. The cylinder is started to drive the piston rod to move the pressure plate closer to the hot press roller 3. Finally, the pressure plate presses the hot press roller 3 tightly against the bottom surface of the mounting frame 8. When it is necessary to replace the hot press roller 3 with a different shaping groove 301, the cylinder is started to drive the piston rod to move the pressure plate away from the hot press roller 3, so that the pressure plate releases the hot press roller 3. At this time, the hot press roller 3 can be replaced. Please see Figure 3 In this embodiment, multiple sets of cylinders are provided, and the multiple sets of cylinders are distributed at intervals along the length direction of the hot press roller 3. Each set of cylinders has a pressure plate installed on its piston rod, which can improve the stability of the hot press roller 3 after installation.

[0043] The method of using the hot-press bonding device in this embodiment includes the following steps: S1. Preliminary gluing: Apply glue to the surface of the wood board B or the film M with a thickness of 0.5-1mm. Cover the three continuous surfaces of the wood board B, including the irregular end B1, with the film M. The worker presses it gently by hand to obtain the preliminarily glued wood board B. S2, End Shaping: The worker manually places the pre-glued wooden board B on the platform 2 between the hot press roller 3 and the flat pusher 4, with the irregular end B1 of the wooden board B facing the shaping groove 301 on the hot press roller 3. Then, the flat pusher 4 is controlled to push the pre-glued wooden board B towards the hot press roller 3, so that the irregular end B1 of the wooden board B, along with the film M, enters the shaping groove 301. Then, the heating element 11 is controlled to heat the hot press roller 3 to 100℃-150℃. After hot pressing for a certain time (usually 1 minute), the end-shaped wooden board B is obtained. Finally, the flat pusher 4 is controlled to move away from the wooden board B. S3. Exhaust by Extrusion: Start two sets of drive sources (gear motors) to drive the two extrusion rollers 5 to rotate. The speed can be set to 0.8m / s. The worker manually raises the end-shaped wooden board B to the same height as the extrusion conveying mechanism, and then pushes the shaped end of the wooden board B into the space between the two extrusion rollers 5. This allows the wooden board B and the film M to be conveyed into the space between the fixed hot press plate 601 and the movable hot press plate 602. During this process, the two extrusion rollers 5 press the film M tightly onto the two opposite surfaces of the wooden board B, and expel the air between the film M and the wooden board B from the irregular end B1 of the wooden board B to the other end. During this process, the worker needs to continuously hold the end of the wooden board B away from the extrusion rollers 5. After the wooden board B separates from the two extrusion rollers 5, the worker needs to manually push the wooden board B completely into the space between the fixed hot press plate 601 and the movable hot press plate 602. It should be noted that after the wooden board B separates from the two extrusion rollers 5, it is generally not recommended for the worker to push the wooden board B directly by hand. Instead, an idle board or other suitable tool can be used. S4. Two-sided shaping: After the wooden board B is fully inserted into the space between the fixed hot press plate 601 and the movable hot press plate 602, the longitudinal pusher 7 is controlled to drive the movable hot press plate 602 to press closer to the wooden board B, so that the movable hot press plate 602 cooperates with the fixed hot press plate 601 to press the two opposing surfaces of the film M and the wooden board B together. The pressing pressure is 0.4MPa. Then, the two hot press plates are heated to 100℃-150℃ and hot-pressed for a period of time (usually 1 minute) to obtain the wooden board B with both ends and both sides shaped. Finally, the longitudinal pusher 7 is controlled to drive the movable hot press plate 602 away from the wooden board B. S5. Material cutting: After the surface temperature of the fixed hot press plate 601 drops below 50℃, the worker manually removes the wood board B, which has been shaped at both ends and on both sides, from the fixed hot press plate 601 to complete the hot press bonding of the wood board B with film.

[0044] Example 2 Based on Example 1, this embodiment further optimizes the installation method of the extrusion roller 5; Please see Figure 3 Multiple sets of auxiliary support members 9 are arranged at intervals along the length direction of the extrusion roller 5 on the mounting frame 8. The auxiliary support members 9 are fixed to the mounting frame 8 by bolts. Each set of auxiliary support members 9 includes a support frame 901 and two guide wheels 902. The two guide wheels 902 are rotatably mounted on the mounting frame 8 through the support frame 901. The two guide wheels 902 are located on both sides of the extrusion roller 5, and both guide wheels 902 are in contact with the outer circular surface of the extrusion roller 5. In this embodiment, the two guide wheels 902 of the auxiliary support member 9 are located on both sides of the extrusion roller 5 and contact the extrusion roller 5. They provide support and guidance for the extrusion roller 5, preventing it from bending and deforming under stress during operation, ensuring uniform pressure between the extrusion roller 5 and the wooden board B, and improving the extrusion and venting effect. Simultaneously, the rolling contact of the guide wheels 902 reduces wear on the extrusion roller 5 and extends its service life. The auxiliary support members 9 are spaced apart along the length of the extrusion roller 5, providing comprehensive support and further enhancing its operational stability.
