Commercially available thermoplastic unidirectional tapes can be consolidated into sheets using this device. Even continuous fiber thermoplastic sheets can be secondary compounded in this device to obtain the required thickness, and sandwich panels can also be produced. Compared with traditional sheet preparation methods, the thermoplastic composite material consolidation and molding device can consolidate different types of sheets according to different needs, greatly improving utilization and design freedom.

[0049] Reference Figure 1 - Figure 9 A support assembly is provided below the lower frame 2, and the support assembly includes two symmetrically arranged support plates 7, which can hold the molding unit, and a support rod 8 is fixed to the lower surface of the support plate 7;

[0050] The heating unit includes a U-shaped plate 9, the open end of the U-shaped plate 9 is opposite to the molding unit, and a plurality of infrared lamps are laid on the inner side wall of the U-shaped plate 9, and the heat generated by the infrared lamps can be radiated to the thermoplastic composite material laid in the molding unit;

[0051] The bottom of the U-shaped plate 9 is symmetrically provided with a base plate 10, and the base plate 10 is provided with a driving assembly, and the driving assembly can drive the U-shaped plate 9 to slide on the base plate 10 and move toward the molding unit, and make the upper surface of the cover plate 3 opposite to the inner top surface of the U-shaped plate 9, and the lower surface of the tray 4 opposite to the inner bottom surface of the U-shaped plate 9; a plurality of support rods 8 are provided to cooperate with the tray 7 to suspend the molding unit, that is, to place the molding unit at a height convenient for staff to operate; after the material is laid, the molding unit is molded, and then the heating unit is moved to the molding unit position by the driving assembly. In this embodiment, the driving assembly provided includes a side plate 11 fixed to the ground, and the side plate 11 is provided close to one side of the molding unit. A motor 12 is symmetrically provided on the side plate 11, and a screw 13 is fixed to the output end of the motor 12. A slider 14 is threadedly connected to the screw 13. The slider 14 passes through the base plate 10 and can slide along the strip hole opened on the base plate 10. The upper end of the slider 14 is fixed to the U-shaped plate 9;

[0052] The motor 12 drives the screw 13, which drives the U-shaped plate 9 to move through the slider 14, so that the U-shaped plate 9 moves toward the molding unit, so that the upper surface of the cover plate 3 is opposite to the inner top surface of the U-shaped plate 9, and the lower surface of the tray 4 is opposite to the inner bottom surface of the U-shaped plate 9. The infrared lamps on the U-shaped plate 9 are connected to the power supply, and the infrared lamps are arranged in multiple rows, and the infrared lamps in adjacent rows are staggered so that the heat generated by the infrared lamps can be radiated to every part of the cover plate 3 and the tray 4;

[0053] Heat is generated and radiated onto the glass cover plate 3 and the tray 4, and the material in the tray 4 is heated. After the heating is completed, the heating unit is evacuated by the driving component; the setting of the U-shaped plate 9 in the heating unit can heat the forming unit in all directions, fully heat every part of the material, heat evenly, and help improve the forming quality of the plate.

[0054] Reference Figure 1 - Figure 7 The cooling unit includes a water tank 15 capable of accommodating the molding unit, and a plurality of screw rods 16 capable of driving the water tank 15 to move up and down are threadedly connected to the outer wall of the water tank 15;

[0055] Each of the support rods 8 is arranged through the bottom plate of the water tank 15, and a sealing rubber ring is provided at the position where the support rod 8 is passed through the bottom plate of the water tank 15. The support rod 8 passes through the sealing rubber ring, and a sealing rubber ring is provided between the support rod 8 and the water tank 15 to ensure the sealing between the support rod 8 and the water tank 15 and reduce the possibility of cooling water in the water tank 15 flowing out; a plurality of water inlet pipes 17 are provided on one side of the water tank 15, and a plurality of water outlet pipes 18 are provided on the other side of the water tank 15;

[0056] After the material is heated, the heating unit is evacuated and the cooling unit is executed. The screw rod 16 can be driven by a motor. The motor drives the screw rod 16 to rotate, and the screw rod 16 pushes the water tank 15 upward to move, so that the molding unit is completely placed in the water tank 15. Then, cooling water is continuously injected into the water tank 15 through an external water pump. The cooling water quickly covers the molding unit, which can quickly cool the molding unit and the material inside, thereby improving the overall processing efficiency of the thermoplastic composite material consolidation molding;

[0057] Taking into account the problem of whether the cover plate 3 and the tray 4 made of glass will burst after being heated and then directly contacted with water, the tray 4 and the cover plate 3 in this embodiment can use some borosilicate glass or quartz glass. These glasses have relatively stable performance and can withstand large temperature differences, so that the molding unit will not burst when it encounters water after being heated. And according to the required temperature of the processed plate, the tray 4 and the cover plate 3 made of suitable glass are selected.

[0058] Reference Figure 3 The connection height of the water inlet pipe 17 and the water trough 15 is lower than the connection height of the water outlet pipe 18 and the water trough 15; the height of the water inlet pipe 17 and the water outlet pipe 18 is set so that the cooling water entering the water trough 15 can quickly replace the original cooling water in the water trough 15, ensuring that the cooling water in the water trough 15 is continuously replaced, which is conducive to the cooling and solidification of the material after molding, improves the cooling and solidification efficiency, and also improves the quality of the final plate product.

[0059] Reference Figure 7 - Figure 9 , a guide plate 19 is provided between the support rods 8 on both sides of the water tank 15, and the cross section of the guide plate 19 is L-shaped. Both ends of the guide plate 19 are fixedly connected to the support rods 8 close thereto, and the driving assembly can drive the U-shaped plate 9 to move to the guide plate 19;

[0060] When the U-shaped plate 9 is pushed to the molding unit position, the end of the U-shaped plate 9 facing away from the molding unit is connected to the drive assembly through the slider 14. The U-shaped plate 9 is in an unstable state. The dead weight of the U-shaped plate 9 will cause the slider 14 or the screw 13 to deform, which will directly affect the expected set distance between the infrared lamp tube and the material, resulting in the heat generated by the infrared lamp tube cannot be evenly radiated to the material. For this purpose, a guide plate 19 is provided. The guide plate 19 is used to support the U-shaped plate 9 to prevent the slider 14 or the screw 13 from deforming; when the U-shaped plate 9 is pushed to the molding unit position, the bottom of the U-shaped plate 9 is supported by the guide plate 19, so that the U-shaped plate 9 can be stably placed in the molding unit position, ensuring that the infrared lamp tube and the molding unit maintain the expected set distance, so that the heat generated by the infrared lamp tube can be evenly radiated to the material, which helps to ensure the uniformity of heating and melting the material.

[0061] Reference Figure 4 , a roller 20 is mounted on the upper surface of the end of the substrate 10 close to the water tank 15, and the movement of the U-shaped plate 9 can rub the roller 20 to rotate; when the U-shaped plate 9 is retracted and reset, the lower open end of the U-shaped plate 9 is supported by the roller 20, and at the same time, the U-shaped plate 9 is away from the end of the molding unit and is lifted by the slider 14, so that the U-shaped plate 9 can be stabilized on the drive assembly, preparing for the subsequent use of the U-shaped plate 9. If there is no support from the roller 20, at this time, after the U-shaped plate 9 is retracted and reset, the end of the U-shaped plate 9 away from the molding unit is lifted by the slider 14. The total gravity of the U-shaped plate 9 and the infrared lamp tube thereon will also cause deformation of the slider 14 and the screw 13; at the same time, the setting of the roller 20 will not affect the movement of the U-shaped plate 9.

[0062] Reference Figure 1 、 Figure 3 、 Figure 5 and Figure 8 , rectangular plates 21 are fixedly connected to both sides of the upper frame 1 and the lower frame 2. When the cover plate 3 and the tray 4 are molded together, the rectangular plates 21 on both sides of the upper frame 1 and the lower frame 2 are aligned and close to each other; U-shaped clamping plates 22 are fixedly connected to both sides of the U-shaped plate 9. The molding unit is located in the U-shaped plate 9, and the clamping plates 22 can clamp the two adjacent rectangular plates 21 above and below;

[0063] The clamping plate 22 is composed of two upper and lower horizontal plates, and the adjacent two horizontal plates are spaced apart. After the cover plate 3 and the tray 4 are molded together, the driving assembly drives the heating unit to move toward the molding unit. At this time, the upper horizontal plate of the clamping plate 22 moves to the rectangular plate 21 on the upper frame 1, and the lower horizontal plate moves to the rectangular plate 21 on the lower frame 2. At this time, the two horizontal plates can clamp the upper and lower rectangular plates 21, thereby clamping the upper frame 1 and the lower frame 2 together, improving the stability and sealing of the cover plate 3 and the tray 4 after the mold is closed;

[0064] At the same time, it is also taken into consideration that the movement of the splint 22 toward the molding unit may push the molding unit to move. In this embodiment, the molding unit is mounted on the support plate 7. The outer side of each support plate 7 can limit the lower frame 2 so that the molding unit can be stabilized. The setting of the support plate 7 also facilitates the rapid positioning of the molding unit, so that the water tank 15 can fully accommodate the molding unit, and the upper and lower plates of the U-shaped plate 9 can be smoothly placed above and below the molding unit.

[0065] Reference Figure 8 Each of the inner top and bottom surfaces of the clamping plates 22 is provided with rolling grooves, and a rotating rod body 23 is provided in the rolling grooves; when the clamping plates 22 clamp the rectangular plate 21, the rod body 23 contacts the rectangular plate 21, and the rod body 23 rotates, which can convert the sliding friction between the clamping plates 22 and the rectangular plate 21 into rolling friction between the rod body 23 and the rectangular plate 21, thereby reducing the resistance to the movement of the heating unit and enabling the drive assembly to execute stably.

[0066] Reference Figure 10 and Figure 11 The cross section of the sealing strip 5 is trapezoidal, and the contact surface of the sealing strip 5 with the cover plate 3 is wavy; a rubber ring 24 is provided on the outer ring of the lower surface of the cover plate 3, and the rubber ring 24 is arranged in conjunction with the sealing strip 5. The cross section of the rubber ring 24 is trapezoidal, and the contact surface between the rubber ring 24 and the sealing strip 5 is wavy; the materials used for the rubber ring 24 and the sealing ring are both made of high-temperature resistant materials. When the material is heated, the rubber ring 24 and the sealing ring will not melt, which can ensure the sealing of the molding unit; at the same time, the setting of the shape of the rubber ring 24 and the sealing ring makes the wavy surface on the rubber ring 24 fit closely with the wavy surface on the sealing ring, which helps to improve the sealing during vacuuming.

[0067] Reference Figure 5 A handle 25 is provided at the outer end of each rectangular plate 21; the handle 25 is provided to facilitate taking and placing the upper frame 1 or the lower frame 2.

[0068] Working principle: First, load the material and lay it in the molding unit. The specific process is to evenly apply the release agent on the tray 4 and the cover plate 3, then lay the material, use an automatic laying machine or manually to complete the material laying, then close the molding unit, install the upper frame 1 on the lower frame 2, and the two rectangular plates 21 on the upper frame 1 and the lower frame 2 are close to each other and aligned. Then, use an external negative pressure pump with a hose, connect the hose with the exhaust hole 6 and extract the air in the tray 4, and then heat it. Use the heating unit to heat the entire molding unit. Infrared lamps can be used to perform infrared radiation heating on the material in the frame, and maintain vacuum during heating;

[0069] The specific heating process is as follows: the motor 12 drives the screw 13, and the screw 13 drives the U-shaped plate 9 to move through the slider 14, so that the U-shaped plate 9 moves toward the molding unit, and the U-shaped plate 9 slides onto the guide plate 19. The guide plate 19 supports and stabilizes the U-shaped plate 9, so that the upper surface of the cover plate 3 is opposite to the inner top surface of the U-shaped plate 9, and the lower surface of the tray 4 is opposite to the inner bottom surface of the U-shaped plate 9. At the same time, it is ensured that the infrared lamp tube and the molding unit maintain the expected set distance. The infrared lamp tube on the U-shaped plate 9 is powered on, generates heat and radiates it to the glass cover plate 3 and the tray 4, and heats the material in the tray 4. After the heating is completed, the heating unit is evacuated by the driving component, and the molding unit is cooled by the cooling unit.

[0070] The specific cooling process is that the motor drives the screw 16 to rotate, and the screw 16 pushes the water tank 15 upward to move, so that the molding unit is completely placed in the water tank 15, and then the external water pump continuously injects cooling water into the water tank 15. The cooling water quickly covers the molding unit and can quickly cool the molding unit and the material inside. After the cooling is completed, the material is unloaded;

[0071] The specific process of unloading is that the motor drives the screw rod 16 to rotate in the opposite direction, the water pump stops supplying water, the forming unit is exposed outside the water tank 15, the forming unit is removed, the cover plate 3 is opened and the processed plate is taken out.

[0072] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
