[0028] Embodiment 1

[0029] A corrugated board forming device is used to form a corrugated structure on a sheet. The corrugated board mainly increases the contact area of parts, enables the diffuser to increase the flow space, and the electrostatic device to increase the dust adsorption area, etc. Currently, the corrugated board forming on the market mainly uses molds or rolling equipment for processing, which greatly restricts the specifications and shapes of the corrugated board forming. Moreover, according to different materials and thickness requirements, the plasticity of the formed corrugated board is limited. At the same time, the corrugated board processed by molds or rolling equipment requires a certain production volume to start production, otherwise the startup cost and material cost are relatively high.

[0030] As Figure 1 、 2 shown, the device mainly includes a rolling surface 2 for carrying the sheet 1, and forming teeth 3 are arranged on the rolling surface 2, that is, the rolling surface 2 is equivalent to a rack.

[0031] It further includes a rolling wheel 4 that can roll relative to the rolling surface 2. The surface of the rolling wheel 4 is provided with rolling teeth that mesh with the forming teeth 3. That is, the rolling wheel 4 and the rolling surface 2 are equivalent to the combined structure of a gear and a rack. Here, the teeth are circular teeth, that is, the teeth have an arc-shaped surface. The rotating shaft 6 of the rolling wheel 4 is fixedly arranged on the U-shaped frame 5. The rotating shaft 6 is supported by a bearing 7 between the rotating shaft 6 and the rolling wheel 4. The rolling wheel 4 can be moved relative to the surface of the rolling wheel 4 by moving the U-shaped frame 5.

[0032] During use, the sheet 1 is placed between the rolling surface 2 and the rolling wheel 4. As shown in the figure, the rolling surface 2 is located below the sheet 1, and the rolling wheel 4 is located above the sheet 1. The rolling wheel 4 and the rolling surface 2 move relative to each other, thereby rolling a corrugated structure on the sheet 1. As a control form of relative movement, it can be that the rolling wheel 4 moves while the rolling surface 2 is stationary, or the rolling surface 2 moves while the rolling wheel 4 is stationary, that is, the position of the U-shaped frame 5 is fixed.

[0033] In order to adjust the depth of the corrugations rolled out, it can be achieved by adjusting the distance between the rolling wheel 4 and the rolling surface 2. The greater the distance between the rolling wheel 4 and the rolling surface 2, the smaller the depth of the corrugations rolled out. On the contrary, the smaller the distance between the rolling wheel 4 and the rolling surface 2, the greater the depth of the corrugations rolled out. For this reason, the rolling wheel 4 can be controlled by a first telescopic mechanism 8 that can lift relative to the rolling surface 2, thereby controlling the distance between the rolling wheel 4 and the rolling surface. The first telescopic mechanism 8 can be a pneumatic cylinder, a hydraulic cylinder, etc., which are convenient for realizing the lifting control of the rolling wheel 4.

[0034] In order to reduce the vibration and noise during rolling, the surface of the forming teeth 3 can have an elastic buffer layer, such as a structural layer made of rubber or nylon material, etc., so as to absorb vibration and reduce noise. In this embodiment, a synchronous belt is directly used as the rolling surface, and the forming teeth are the teeth of the synchronous belt. The synchronous belt is an endless belt with a steel wire rope or fiberglass as the reinforcing layer and polyurethane or neoprene rubber on the outside. In this way, the forming teeth can have better oil resistance, wear resistance and anti-aging properties.

[0035] In order to ensure the stable position of the sheet 1 during rolling, sheet position limiting blocks 9 for guiding and limiting the sheet 1 are provided on both sides of the forming teeth 3. Of course, the distance between the sheet position limiting blocks 9 on both sides can be set according to the width of the sheet 1. In this embodiment, the synchronous belt is arranged in a groove body, and the two side walls of the groove body are the sheet position limiting blocks 9. The synchronous belt is fixedly bonded to the bottom of the groove body. The synchronous belt is an arc tooth synchronous belt, that is, its teeth are circular arcs, thus forming an arc-shaped corrugated structure. The surface of the rolling wheel is fixedly surrounded by the synchronous belt, and the teeth of the synchronous belt are used as the rolling teeth, and the teeth of the synchronous belt are also circular arc teeth.

[0036] For convenience, an existing milling machine can be used as the operating machine. The groove body is fixedly installed on the milling machine platform, and the U-shaped frame 5 of the rolling wheel 4 is installed on the milling cutter holder of the milling machine; the reciprocating movement of the milling machine platform drives the rolling wheel 4 to rotate, so as to realize the movement of the rolling surface 2 relative to the rolling wheel 4 by the movement of the milling machine platform relative to the milling cutter, and the depth of the corrugation is controlled by adjusting the height of the milling cutter holder. The groove body is preferably processed with No. 45 steel material, and the internal groove width is designed according to the part requirements; the two sides of the groove body are fixed on the milling machine platform with angle steel.

[0037] Embodiment 2

[0038] As Figure 3 、 4 、5 shows, different from the above embodiment, in order to improve the application range of the device, the sheet position limiting block 9 is an adjustable sheet position limiting block 9. The sheet position limiting block 9 includes a block 10 that can be pressed against both sides of the sheet. A pressing guide wheel 11 that is in rolling contact with the sheet 1 is arranged on the block 10. The pressing guide wheel 11 can reduce the friction between the block 10 and the sheet 1, so as to prevent the sheet 1 from moving in the left-right direction as shown in the figure, and reduce the resistance to the movement of the sheet 1 in the up-down direction as shown in the figure, thus facilitating the deformation of the sheet 1 during rolling.

[0039] The stopper 10 is connected to a slider 12 that can move relative to the rolling surface. In this embodiment, the stopper 10 and the slider 12 are connected by a connecting rod 13. The connecting rod 13 is slidably fitted in the tooth groove between two teeth of the forming tooth 3, so that the tooth groove plays a certain guiding role in the movement of the connecting rod 13. The slider 12 is slidably arranged on a slide rail 14. A return spring 15 is supported at the end of the slider 12 and the slide rail 14. The return spring 15 provides the pressing force of the stopper 10 against the plate 1. Since the stopper 10 realizes the floating clamping of the plate 1 by using the return spring 15, the position of the stopper 10 has a certain adjustment ability, that is, the distance between two stoppers 10 opposite to each other can be changed according to the plates 1 of different widths, so that it can be adapted to the use of plates 1 changing within a certain width range, improving the versatility of the device.

[0040] Further, push plates 16 are arranged on both sides of the U-shaped frame 5. The front and rear ends of the push plates 16 are provided with guiding inclined surfaces 17 that are bent towards the rolling wheels 4. The length of the middle part of the push plates 16 between the front and rear guiding inclined surfaces 17 is greater than the diameter of the rolling wheels 4. When the push plates 16 move relative to the rolling surface along with the U-shaped frame 5, under the guiding action of the guiding inclined surfaces 17, they can push the contacting sliders 12 towards both sides, so that the distance between two opposite stoppers 10 allows the rolling wheels 4 to pass through, that is, the distance between the two sides of the rolling wheels 4 guided by the middle part of the push plates 16 is greater than the distance between the stoppers 10 and the sliders 12. Thus, when the sliders 12 are located at the middle part of the push plates 16, the stoppers 10 connected to them by the connecting rods 13 are separated towards both sides to prevent them from hindering the movement of the rolling wheels 4 relative to the rolling surface. Guide wheels 18 that can be in rolling contact with the push plates 16 are arranged on the sliders 12 to reduce the friction force of the sliders 12 moving relative to the push plates 16. Designed in this way, not only can the stoppers 10 be applicable to plates 1 of different widths, but also the rolling wheels 4 can be suitable for plates 1 of different widths, that is, a wider rolling wheel 4 can be suitable for rolling a narrower plate 1. The middle part of the push plates 16 is fixedly connected to the U-shaped frame 5 through a support rod 19.

[0041] Furthermore, the distance between the slide rail 14 and the rolling surface 2 can be adjusted by a moving adjustment device 20, that is, the distance between the slide rail 14 and the rolling surface 2 can be changed. As a result, the distance between two opposite stoppers 10 in the free state of the return spring 15 can also be changed, facilitating the placement of the sheet 1 on the rolling surface 2 or the removal of the rolled finished product from the rolling surface 2. That is, before placing the sheet 1, the slide rail 14 can be moved away from the rolling surface 2 first, increasing the distance between two opposite stoppers 10. After placing the sheet 1 on the rolling surface 2, the slide rail 14 is then moved closer to the rolling surface 2, causing the stoppers 10 to clamp the rolling surface 2. The moving adjustment device can also be a telescopic control mechanism such as a pneumatic cylinder or a hydraulic cylinder.

[0042] Furthermore, bristles in contact with the forming teeth 3 can be provided under the stoppers 10, so that when the stoppers 10 move relative to the forming teeth 3, the bristles can clean the forming teeth 3.

[0043] Furthermore, the guiding inclined surface 17 is an arc-shaped guiding inclined surface 17, so that the compression speed of the return spring 15 is opposite to the change in the acting force, making the force on the push plate 16 more stable during movement. Of course, the guiding inclined surface 17 can also be other forms of inclined surfaces, such as a straight inclined surface instead of an arc-shaped one, as long as it can cause the stoppers 10 to separate to both sides. For example, the guiding inclined surface 17 can be an inclined surface at a 45-degree angle to the moving direction of the rolling wheel 4.
