[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are intended only to illustrate the relevant utility model and are not intended to limit the scope of the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.

[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] Please refer to Figures 1 to 4 , an embodiment of the utility model provides a leveling device for a laser blanking line, comprising a frame 1, a leveling assembly 2, a guide assembly 3 and a workbench 4; the frame 1 is provided with two groups, and the two groups of frames 1 are symmetrically arranged on the top surface of the workbench 4; the leveling assembly 2 is arranged between the frames 1, and comprises a plurality of upper leveling rollers 21 and a plurality of lower leveling rollers 22 which are parallel and staggered up and down. Specifically, the plurality of upper leveling rollers 21 are arranged in parallel in a row, and the plurality of lower leveling rollers 22 are arranged in parallel in a row, and the number of the lower leveling rollers 22 is one more than the number of the upper leveling rollers 21. The upper leveling rollers 21 and the lower leveling rollers 22 are staggered. When the metal sheet passes through the upper leveling rollers 21 and the lower leveling rollers 22, the metal sheet is bent forward and backward for multiple times, so that the multiple original curvatures are gradually changed into a single curvature, thereby achieving leveling;

[0029] The guide assembly 3 is arranged at one end of the frame 1, and includes a guide roller 31, a limit plate 32 and a threaded rod 33. The guide roller 31 is rotatably connected between the frame 1, and the outer surface of the guide roller 31 is slidingly sleeved with two groups of limit plates 32. The threaded rod 33 is arranged parallel to the guide roller 31 and the thread passes through the frame 1. One end of the threaded rod 33 is rotatably connected to the limit plate 32, and a slider 34 is slidably provided on the opposite surface of the limit plate 32. A spring 35 is provided on the top of the slider 34, and the opposite surface of the slider 34 is rotatably connected to the limit roller 36; specifically, a sliding groove is opened on the opposite surface of the limit plate 32 in the vertical direction, and the slider 34 is slidably connected to the inner wall of the sliding groove. A spring 35 is provided at the top of the slider 34 in the sliding groove, and one end of the spring 35 is fixedly connected to the top of the slider 34, and the other end is fixedly connected to the inner wall of the sliding groove. When not affected by external force, the elasticity of the spring 35 The slider 34 can be moved downward, thereby driving the limiting roller 36 to move downward. When the metal sheet is leveled, the limiting roller 36 contacts the top surface of the metal sheet; when the metal sheet is leveled, the metal sheet is located between the two limiting plates 32, and the rotating threaded rod 33 drives the limiting plates 32 to approach each other, limiting the metal sheet to avoid the metal sheet from offsetting during the leveling transmission, thereby improving the effect of subsequent laser cutting; at the same time, the limiting roller 36 contacts the top surface of the metal sheet to avoid the metal sheet from being squeezed and tilted when passing through the upper leveling roller 21 and the lower leveling roller 22; and each limiting plate is driven by a threaded rod respectively, and the distance or offset position between the two limiting plates 32 can be adjusted according to actual needs such as the width of the metal sheet and the cutting requirements, so that the metal sheet can be kept in the middle position, or the metal sheet can be moved to the left or right.

[0030] In a preferred embodiment, if Figure 4 As shown, the opposite surface of the slider 34 is rotatably provided with a rotating roller 37 located below the limiting roller 36, and the rotating roller 37 is arranged in the vertical direction. When limiting the position of the metal sheet, the side of the metal sheet contacts the rotating roller 37. When the metal sheet is leveled and moved, the rotating roller 37 rotates due to friction, making the metal sheet move more smoothly and preventing the side of the limiting plate 32 from directly contacting the side of the metal sheet, causing significant friction and affecting the transmission of the metal sheet.

[0031] In a preferred embodiment, if Figure 1 and Figure 3 As shown, the workbench 4 is also provided. A scale 5 is provided on the top surface of the workbench 4 below the limit plate 32. The scale 5 is arranged parallel to the guide roller 31. A pointer is provided at the bottom of the limit plate 32. The bottom end of the pointer is aligned with the scale of the scale. According to actual needs, the limit plate 32 needs to be moved to the predetermined position when the metal sheet moves to the left, right, or along the middle. By observing the scale of the scale 5, the limit plate 32 can be moved to the predetermined position accurately, thereby improving the subsequent laser cutting effect.

[0032] In a preferred embodiment, if Figure 1 and Figure 3 As shown, a rotating handle 38 is provided at one end of the threaded rod 33 away from the limiting plate 32 .

[0033] In a preferred embodiment, if Figure 2 As shown, multiple lower leveling rollers 22 are arranged in parallel. One end of each of the lower leveling rollers 22 on the same side passes through the frame 1 and is connected to a first transmission wheel 23. The outer surfaces of the multiple first transmission wheels 23 are covered with a common first transmission belt 24. One end of one of the lower leveling rollers 22 is connected to a first motor 25 that drives its rotation. The use of a single first motor 25 to drive the multiple lower leveling rollers 22 to rotate synchronously saves on the use of motors and reduces the production cost of the leveling device.

[0034] In a preferred embodiment, if Figure 2 As shown, a cylinder 6 is provided on the top of the frame 1, and the output end of the cylinder 6 is connected to a mounting plate 7. A plurality of upper leveling rollers 21 arranged in parallel are provided below the mounting plate 7 through a fixing frame.

[0035] In a preferred embodiment, if Figure 2 As shown, one end of the same side of multiple upper leveling rollers 21 passes through the mounting plate 7 and is connected to a second transmission wheel 26. The outer surfaces of the multiple second transmission wheels 26 are sleeved with the same second transmission belt, and one end of one of the upper leveling rollers 21 is connected to a second motor 27 that drives it to rotate.

[0036] Working principle:

[0037] When leveling the metal sheet, one end of the metal sheet is pulled through the guide roller 21 and the limiting roller 26, and then passes through the upper leveling roller 21 and the lower leveling roller 22 in sequence. The limiting roller 26 contacts the top surface of the metal sheet under the elastic action of the spring 35, limiting the metal sheet and preventing it from tilting. The threaded rod 33 is then rotated to drive the two limiting plates 22 closer to each other until the rotating roller 37 contacts the side of the metal sheet. The metal sheet is guided by the limiting plates 22 to prevent it from deflecting during the leveling transmission process, thereby improving the subsequent laser cutting effect. Each limiting plate is driven by a threaded rod, and the distance or offset position between the two limiting plates 32 can be adjusted according to the actual needs such as the width of the metal sheet and the cutting requirements, so that the metal sheet remains in the center position or can be moved to the left or right.
