[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0023] Embodiment 1, as Figures 1-4 shown, a flexible bending and forming device includes an overall structure 1 and an auxiliary structure 2. The auxiliary structure 2 is located at the front and rear positions on both sides of the bottom of the overall structure 1; the overall structure 1 includes a bottom plate 101. One side of the top of the bottom plate 101 is fixedly connected with a fixed plate 103. The front and rear positions of the inner top of the fixed plate 103 are fixedly installed with a first telescopic rod 108. The extending end of the first telescopic rod 108 is fixedly connected with a first frame 105. A compression spring 109 is sleeved on the outer surface of the first telescopic rod 108. The center of the front inner surface of the first frame 105 is rotatably connected with a rotating shaft 107. The rear end face of the rotating shaft 107 is fixedly connected with a first round roller 104. A servo motor 106 is fixedly installed at the position of the rotating shaft 107 on the front outer surface of the first frame 105. The center of the top of the bottom plate 101 is fixedly connected with a second frame 110.

[0024] The effect achieved by the entire Embodiment 1 is, as Figure 1 and Figure 2 shown, when the first telescopic rod 108 extends or retracts subsequently, it will drive the first frame 105, the first round roller 104, the rotating shaft 107 and the servo motor 106 to move up and down together, so that the first round roller 104 can normally contact the outer surface of the PVC board. When contacting, with the cooperation of the second round roller 102, the PVC board can be clamped. The first round roller 104 uses the expansion force of the compression spring 109 and the force of the extension of the first telescopic rod 108 to ensure that the PVC board can be stably located between the first round roller 104 and the second round roller 102.

[0025] Example 2, as Figures 1-4 shown, one end of the compression spring 109 is fixedly connected to the inner top of the fixed plate 103, the other end of the compression spring 109 is fixedly connected to the top surface of the first frame 105, a second round roller 102 is rotatably connected to a position near the bottom of the inner surface of the fixed plate 103, the outer surface of the rear side of the first round roller 104 is rotatably connected to the inner surface of the rear side of the first frame 105, one end of the rotating shaft 107 is fixedly connected to the outer surface of the front side of the first round roller 104, the other end of the rotating shaft 107 penetrates through the outer surface of the first frame 105 and is fixedly connected to the driving end of the servo motor 106, second telescopic rods 112 are fixedly installed at the front and rear positions of the inner top and inner bottom of the second frame 110, a round rod 111 is fixedly connected to the extending end of the second telescopic rod 112, the outer surface of the round rod 111 is slidably connected to the inner surface of the second frame 110, a third frame 113 is fixedly connected to the other side of the top of the bottom plate 101, a third round roller 114 is rotatably connected to the center of the front and rear inner surfaces of the third frame 113, third telescopic rods 116 are fixedly installed at the front and rear other sides of the top of the third frame 113, a roller 115 is fixedly connected to the extending end of the third telescopic rod 116, the auxiliary structure 2 includes a connecting rod 201, an anti-slip pad 202 is fixedly connected to the bottom end face of the connecting rod 201, and the top end face of the connecting rod 201 is fixedly connected to the bottom surface of the bottom plate 101.

[0026] The effect achieved by the entire Example 2 is that, as Figure 1 and Figure 3 shown, subsequently when the second telescopic rod 112 extends or retracts, it will drive the round rod 111 to slide up and down in the second frame 110. After the round rod 111 moves to a suitable position, it can contact the middle part of the PVC board, so as to support and clamp the middle part of the PVC board, ensuring that it can be more stable during subsequent bending. The setting of the connecting rod 201 and the anti-slip pad 202 can improve the overall stability during use.

[0027] Working principle: The user first places the PVC board between the first round roller 104 and the second round roller 102 from one side. After placing it, the first telescopic rod 108 extends, driving the first frame 105, the servo motor 106, the rotating shaft 107 and the first round roller 104 to descend. After descending to an appropriate position, the first round roller 104 will contact the outer surface of the PVC board. Then, through the cooperation of the second round roller 102, it can be clamped. Then the servo motor 106 operates, enabling the rotating shaft 107 to rotate. The rotating shaft 107 then drives the first round roller 104 to rotate. In this way, the first round roller 104 can play a guiding role while applying force, guiding the PVC board to the other side. Eventually, the PVC board can enter between the two round rods 111. Then the second telescopic rod 112 extends, enabling the round rods 111 to move up or down within the second frame 110, so that the outer surface of the round rods 111 can contact the middle part of the PVC board. Once in contact, it can be clamped. Finally, the PVC board will be conveyed onto the third round roller 114. Then, through the cooperation of the third telescopic rod 116 and the roller 115, the bending operation of the PVC board can be carried out.

[0028] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
