[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] This utility model provides a technical solution: such as Figure 1-6 As shown, a high-efficiency device for symmetrically compounding double-sided thermoplastic prepreg with PET foam includes a processing box 1. Two unwinding rollers 6 are symmetrically installed on the outer side of the processing box 1. A winding roller 5 is installed on the side of the processing box 1 away from the unwinding rollers 6. The rotation of the unwinding rollers 6 and the winding roller 5 is driven by an external drive source. It should be noted that the double-sided thermoplastic prepreg and PET foam are generally wound in roll form, which is convenient for storage and transportation. Therefore, they are also suitable for unfolding on the unwinding rollers 6.

[0025] Multiple guide rollers 9 are symmetrically rotatably connected inside the processing box 1. A cleaning mechanism is provided inside the processing box 1 and is located between the multiple guide rollers 9. The cleaning mechanism includes an assembly base 23, which is fixedly installed inside the processing box 1. Trapezoidal dust suction channels 24 are fixedly installed on the upper and lower end faces of the assembly base 23. Two trapezoidal dust suction channels 24 are connected through a connecting pipe group 25. Negative pressure dust suction mechanisms are provided on both outer sides of the processing box 1, and each negative pressure dust suction mechanism is connected to the connecting pipe group 25. Two connecting rods 29 are symmetrically rotatably connected on both outer sides of the assembly base 23. A rotating mechanism is provided inside the assembly base 23, and the rotating mechanism drives multiple connecting rods 29 to rotate. A fixing plate is installed at an inclination for every two corresponding connecting rods 29. A cleaning plate 31 is fixedly installed on the outer side of each fixing plate through multiple spring telescopic rods 30.

[0026] The spring telescopic rod 30 ensures that the cleaning plate 31 can adapt to the unevenness of the material surface and clean the material surface. At the same time, the negative pressure dust collection mechanism generates negative pressure on the trapezoidal dust collection channel 24 through the connecting pipe group 25, sucking the cleaned dust and other impurities into the vacuum cleaner 7, thereby achieving efficient cleaning of the material surface and ensuring the composite quality.

[0027] The processing box 1 is equipped with a pressing mechanism. A hot air conveying device 11 is installed on the bottom wall of the processing box 1, and the hot air conveying device 11 is located below the pressing mechanism. Multiple rotating rollers 8 are rotatably connected to the inner walls on both sides of the processing box 1. A cold air conveying device 10 is installed on the bottom wall of the processing box 1, and the cold air conveying device 10 is located below the multiple rotating rollers 8. A tensioning mechanism is provided inside the processing box 1. It should be noted that both the hot air conveying device 11 and the cold air conveying device 10 are existing mature technologies. The hot air conveying device 11 is mainly used to heat the material to soften the thermoplastic prepreg, making it easier to better laminate with PET foam. The cold air conveying device 10 is used to cool and shape the laminated material, improving the molding quality of the material.

[0028] Furthermore, the rotating mechanism includes two drive gears 27, which are rotatably connected to the two outer sides of the mounting base 23 respectively. One end of each connecting rod 29 is equipped with a driven gear 28, and each driven gear 28 is rotatably connected to the outer side of the mounting base 23. Each driven gear 28 meshes with the corresponding drive gear 27. A drive motor 26 is fixedly installed on the inner side of the mounting base 23, and one of the drive gears 27 is installed on the output shaft of the drive motor 26. This allows the cleaning mechanism to be hidden, making it easier for operators to guide materials to be placed inside the device.

[0029] Furthermore, each negative pressure dust collection mechanism includes a dust collector 7, and two dust collectors 7 are respectively fixedly installed on the two outer sides of the processing box 1. The bottom surface of each dust collector 7 is fixed and connected to a dust discharge pipe 19. The bottom end of each dust discharge pipe 19 is fixedly installed with a connecting flange 20. Multiple hooks are installed on the outer side of each connecting flange 20. The outer side of each dust collector 7 is fixed and connected to a dust collection pipe 21. The outer side of the connecting pipe assembly 25 is fixed and connected to a U-shaped pipe 22. Each dust collection pipe 21 is connected to the U-shaped pipe 22. When the dust collector 7 is started, negative pressure is generated, and dust collection is performed on the trapezoidal dust collection channel 24 through the dust collection pipe 21, U-shaped pipe 22 and connecting pipe assembly 25. The impurities cleaned by the cleaning mechanism are discharged through the dust discharge pipe 19.

[0030] Furthermore, the pressing mechanism includes multiple first electric push rods 12, which are symmetrically installed on the top wall of the processing box 1. The bottom ends of the multiple first electric push rods 12 are jointly mounted on a mounting plate 14. Multiple extrusion rollers 15 are rotatably connected to the lower end face of the mounting plate 14. Multiple pressure rollers 13 are rotatably connected to the inner walls on both sides of the processing box 1. The hot air conveying device 11 is located directly below the multiple pressure rollers 13. When the first electric push rods 12 extend, they drive the mounting plate 14 and the extrusion rollers 15 to descend, extruding the material. Through the cooperation of the extrusion rollers 15 and the pressure rollers 13, the material is tightly pressed together.

[0031] Furthermore, the tensioning mechanism includes two mounting frames 16, which are symmetrically installed inside the processing box 1 and located on the two outer sides of the mounting plate 14. Each mounting frame 16 has multiple second electric push rods 17 fixedly installed at its top, and the top of each second electric push rod 17 is fixedly installed on the top wall of the processing box 1. Each mounting frame 16 has two tensioning rollers 18 symmetrically rotatably connected inside. During material processing, the second electric push rods 17 can adjust the height of the mounting frame 16 as needed, thereby changing the position of the tensioning rollers 18 to tension the material, preventing the material from loosening during processing and ensuring the stability and quality of processing.

[0032] Furthermore, a cover plate 2 is detachably installed on the outside of the processing box 1, a viewing window is provided on the outside of the cover plate 2, multiple handles 3 are symmetrically installed on the outside of the cover plate 2, and a controller 4 is installed on the outside of the processing box 1.

[0033] This utility model provides a high-efficiency equipment for symmetrically compounding double-sided thermoplastic prepreg and PET foam. The specific working principle is as follows: First, the double-sided thermoplastic prepreg and PET foam are respectively wound on the unwinding roller 6. Then, the cover plate 2 of the processing box 1 is opened, and the material is passed through the guide roller 9, the cleaning mechanism, the pressing mechanism, the tensioning mechanism and the rotating roller 8 in sequence, and finally fixed on the take-up roller 5.

[0034] Close the cover 2, start the controller 4, and the equipment starts to operate. The vacuum cleaner 7 starts first, creating a negative pressure suction environment for the cleaning mechanism. Then the drive motor 26 runs, and its output shaft drives the drive gear 27 to rotate. Through gear meshing, the driven gear 28 drives the connecting rod 29 to rotate, so that the cleaning plate 31 is precisely close to the material surface. The spring telescopic rod 30 plays an adaptive adjustment role, fitting the slight undulations of the material surface and cleaning and loosening the impurities on the material surface. At the same time, the negative pressure generated by the vacuum cleaner 7 is transmitted to the trapezoidal suction channel 24 through the suction pipe 21, U-shaped pipe 22 and connecting pipe group 25, quickly sucking away the cleaned impurities and ensuring that the surface of the material is clean when it enters the subsequent process.

[0035] When the cleaned material arrives at the pressing mechanism, multiple first electric push rods 12 extend synchronously, pushing the mounting plate 14 and the extrusion roller 15 below to slowly descend. At the same time, the hot air conveying device 11 operates, releasing high-temperature airflow to preheat the material, causing the double-sided thermoplastic prepreg to soften. Under the synergistic extrusion of the extrusion roller 15 and the pressure roller 13, the softened thermoplastic prepreg tightly adheres to the PET foam, achieving composite processing of the two.

[0036] Meanwhile, when the equipment is running, the height of the mounting frame 16 can be flexibly adjusted by the second electric push rod 17, which drives the tension roller 18 to move up or down, always keeping the material in a moderate tension state, preventing wrinkles, loosening or other conditions during transmission, and ensuring the stability of composite processing. Finally, the material after composite processing is guided by the rotating roller 8 and wound up under the traction of the winding roller 5.

[0037] Throughout the entire operation of the equipment, operators can monitor the material processing status in real time through the viewing window on the cover plate 2, and adjust the operating parameters of each mechanism as needed with the help of the controller 4, so as to ensure that the equipment produces high-quality composite products efficiently and stably.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
