However, during the sheet shaping process, the sheet's position may shift as it passes through the extrusion rollers, resulting in uneven stress on the sheet. This causes uneven edges, curling, excessive indentation, and other defects, affecting the sheet processing accuracy and quality. Utility Model Content

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.
[0027] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.
[0028] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.
[0029] Combined with appendix Figure 3 and Figure 4 As shown, a PS sheet shaping device includes a base 1, on which upright plates 2 are symmetrically arranged. Shaping rollers 3 are rotatably connected to the two upright plates 2. One of the upright plates 2 is provided with a drive assembly connected to the shaping roller 3. In the above structure, in order to facilitate the replacement of different types of shaping rollers 3 and to shape the sheet into different shapes according to different requirements, mounting seats 20 are rotatably connected to both upright plates 2. The mounting seats 20 are provided with mounting grooves 21. The rotating shafts at both ends of the shaping roller 3 are inserted into the mounting grooves 21 and fixedly connected to the mounting seats 20 by bolts.
[0030] With the above structure, the rotating shafts at both ends of the shaping roller 3 are provided with screw grooves, and the mounting base 20 is provided with screw holes of the same size as the screw grooves. During installation, the rotating shaft of the shaping roller 3 is inserted into the mounting groove 21 so that the screw holes are aligned with the screw grooves. Then, bolts are used to fix the rotating shaft of the shaping roller 3 to the mounting base 20. The inner diameter of the mounting groove 21 is the same as the size of the rotating shaft of the shaping roller 3. This design facilitates the replacement of the shaping roller 3, and it can be replaced with shaping rollers 3 with different textures to meet different sheet shaping requirements.
[0031] In sheet extrusion and shaping, it may be necessary to extrude the sheet into different thicknesses, therefore, combined with... Figure 3 and Figure 5 As shown, two upright plates 2 are connected to a fixed frame 5 by an upright rod 4. The fixed frame 5 is connected to a height-adjustable bracket 6. A pressure roller 7 is rotatably connected to the bracket 6. A hydraulic cylinder 18 is provided at the center of the fixed frame 5. The bracket 6 is connected to the telescopic end of the hydraulic cylinder 18. The bracket 6 is provided with a kit 19 on both sides. The inner diameter of the kit 19 is adapted to the upright rod 4. The upright rod 4 is inserted into the kit 19.
[0032] During use, the support 6 is raised and lowered by the hydraulic cylinder 18, thereby adjusting the distance between the pressure roller 7 and the shaping roller 3 to adapt to the pressing requirements of sheets of different thicknesses and apply the required pressing pressure. The kit 19 is slidably sleeved on the upright 4 and is adapted to the upright 4, which can ensure the stability of the support 6 when the pressure roller 7 acts on the sheet, reduce the shaking of the support 6, thereby reducing the impact on the hydraulic cylinder 18 and ensuring the safe operation of the hydraulic cylinder 18.
[0033] Among them, the combination of appendix Figure 1 and Figure 2 As shown, the drive assembly includes a second motor 22 fixed on the base 1. The output end of the second motor 22 is connected to a first pulley 23. One end of the shaft of a mounting base 20 passes through the first vertical plate 2 and is connected to a second pulley 24. Both the first pulley 23 and the second pulley 24 are toothed. The first pulley 23 is connected to the second pulley 24 by a toothed belt. The size of the first pulley 23 is smaller than that of the second pulley 24. The movement of the large pulley by the small pulley can slow down the rotation speed of the shaping roller 3 connected to the second pulley 24.
[0034] The specific pressing and shaping process of PS sheet is as follows: after adjusting the distance between the pressure roller 7 and the shaping roller 3, the sheet passes between the pressure roller 7 and the shaping roller 3. The motor 22 drives the pulley 23 to rotate. Through the transmission of the toothed belt, the shaping roller 3 rotates. The pressure roller 7 presses on the sheet and applies moving pressure to it, so that the sheet can be conveyed forward after pressing, thereby completing the shaping of the sheet.
[0035] During the forward conveying of the sheet by the shaping roller 3, its position on the roller 3 may shift, potentially causing uneven stress on the sheet, leading to bending and affecting its quality. Therefore, in conjunction with the attached... Figure 1 As shown, the base 1 is symmetrically provided with two vertical plates 8 on one side of the shaping roller 3. A bidirectional lead screw 9 is rotatably connected between the two vertical plates 8. A motor 10 is fixed on one of the vertical plates 8. The output end of the motor 10 is connected to one end of the bidirectional lead screw 9. A symmetrically arranged height-adjustable sliding table 11 is threaded onto the bidirectional lead screw 9. A limiting plate 12 is provided on one side of the sliding table 11.
[0036] The sliding table 11 is located on one side of the shaping roller 3. During use, the bidirectional lead screw 9 is driven to rotate by the motor 10 to adjust the distance between the two symmetrically arranged sliding tables 11, thereby changing the distance between the two limiting plates 12. This makes the distance between the two limiting plates 12 the same as the width of the sheet to be shaped, thus playing a guiding and limiting role, preventing the sheet from shifting in position during forward conveying, keeping it always in the optimal pressing and shaping position, ensuring uniform force on the sheet, and improving the quality of sheet pressing and shaping.
[0037] When changing to different types of shaping rollers 3, the surface of the sliding table 11 may not be on the same axis as the outer diameter of the shaping roller 3. Therefore, in conjunction with the attached... Figure 1 and Figure 6 As shown, a hydraulic cylinder 13 is connected to the center of the bottom of the sliding table 11. The bottom surface of the sliding table 11 is connected to the telescopic end of the hydraulic cylinder. A connecting block 14 is connected to the bottom of the hydraulic cylinder body and contacts the bottom surface of the base 1. The connecting block 14 is threadedly connected to the bidirectional lead screw 9. Telescopic rods 15 are symmetrically connected to both sides of the bottom surface of the sliding table 11 on the hydraulic cylinder 13. An auxiliary wheel 16 is connected to the bottom of the telescopic rod 15 and contacts the base 1.
[0038] The hydraulic cylinder 13 drives the sliding table 11 to change the height of the table surface, ensuring that the sliding table 11 and the top of the shaping roller 3 are on the same horizontal plane, so as to better receive the shaped sheet and avoid the bending of the sheet due to height deviation. The design of the telescopic rod 15 and the auxiliary wheel 16 connected to it can better share the force of the bidirectional lead screw 9. The auxiliary wheel 16 reduces the friction when the sliding table 11 moves, making the adjustment of the spacing of the sliding table 11 smoother.
[0039] Combined with appendix Figure 6 As shown, a conveyor belt 17 is connected to the sliding table 11. The conveyor belt 17 facilitates the transport of the shaped sheet. A guide plate is connected to the side of the sliding table 11 near the shaping roller 3, so that the sheet can fall onto the conveyor belt 17 better.
[0040] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
