[0002] Aluminum sheet refers to a sheet material made of aluminum or aluminum alloy, or a sheet aluminum product made from aluminum blanks through heating and rolling. Long strips of aluminum sheet must be straightened before they can be further processed into other products.

[0003] A Chinese patent (publication number: CN212190672U) discloses an aluminum sheet straightening device. This device features a front straightening assembly and a rear straightening assembly to the right of a straightening ball (the aluminum sheet moves from right to left). The straightening assembly has two rollers spaced apart, which restrict the sheet's forward and backward swing. However, this device still has the following shortcomings: 1. Because the rollers are fixed in position, jamming can occur when the sheet's side straightness tolerances are large. 2. The lack of support to the left of the straightening ball causes the straightened sheet to sag under gravity, resulting in an arc-shaped shape, which affects the sheet's subsequent use.

[0004] Therefore, we have designed an aluminum plate straightening device to solve at least one of the above-mentioned deficiencies. Utility Model Content

The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention. In the description of the present invention, it should be understood that if there are terms such as "upper", "lower", "front", "back", "left", "right" and so on to indicate directions or positional relationships, they only correspond to the drawings of the present application and are for the convenience of describing the present invention; it should be understood that if there are terms such as "end", "side", "end part", "lateral", "transverse", "longitudinal" and so on to indicate directions or positional relationships, they only correspond to the length and width of the corresponding parts, that is, "end part" indicates the head and tail area of the corresponding part in the length direction, and "side part" indicates the head and tail area of the corresponding part in the width direction; this is for the convenience of describing the present invention and does not indicate or imply that the device or element referred to must have a specific direction.

[0027] Example 1, combined with the attached Figure 1-3 , an aluminum plate straightening device, comprising a straightening component 1 and a straightening component 2;

[0028] The straightening assembly 1 comprises two upright posts 11 symmetrically arranged on the left and right sides, and a lower straightening roller 12 with a fixed height and an upper straightening roller 13 with an adjustable height are rotatably connected between the two upright posts 11 .

[0029] As needed, the straightening roller includes a roller shaft and a sleeve fixedly mounted in the middle of the roller shaft body, that is, the length of the roller shaft is greater than the length of the sleeve, so that the straightening roller has protruding shaft heads at both ends; the shaft heads at both ends of the straightening roller are connected to the corresponding columns 11 through bearings.

[0030] Furthermore, both shaft ends of the upper straightening roller 13 are rotatably connected to sliders 15 , and the sliders 15 are connected to the corresponding columns 11 in an up-and-down sliding manner; the columns 11 are provided with an adjustment structure for adjusting the height of the sliders 15 .

[0031] In a possible embodiment, a vertical slide rail is provided on the inner side of the column 11 , and the slide rail and the slider 15 are connected so that the slider 15 can slide up and down.

[0032] In another possible example, the column 11 is provided with a vertical slide groove 111, and the slider 15 is connected to the corresponding inner cavity of the slide groove 111 by sliding up and down; as needed, the two inner side walls of the slide groove 111 can be provided with vertical slide rails, and the slider 15 can slide up and down through the slide rails and the slider 15; the top wall of the slide groove 111 is threadedly connected with a penetrating adjusting screw 16, and the lower end of the adjusting screw 16 is rotatably connected to the corresponding slider 15; that is, by rotating the adjusting screw 16, the adjusting screw 16 can be raised or lowered, thereby driving the corresponding slider 15 to rise or fall, thereby realizing the function of adjusting the height of the upper straightening roller 13.

[0033] Furthermore, a compression spring 17 is provided between the inner bottom surface of the slide groove 111 and the bottom surface of the corresponding slider 15; when adjusting the spacing between the lower straightening roller 12 and the upper straightening roller 13, the adjusting screw and the upper straightening roller 13 are always at the upper limit position of the thread fit tolerance between the adjusting screw and the column under the action of the compression spring 17, so that the upper straightening roller 13 will not deviate upward due to the existence of the thread fit tolerance during the process of straightening the workpiece, thereby affecting the straightening effect; that is, the slider 15 is always subjected to the top force of the compression spring 17, which is used to supplement the adjusting screw 16 and the fitting tolerance of the thread fit between the column 11; that is, the distance between the lower straightening roller 12 and the upper straightening roller 13 before and after work will not be affected by the fitting tolerance of the thread fit; in other words, when there is no compression spring 17, the upper straightening roller 13 is located at the lower limit of the fitting tolerance of the thread fit under the action of gravity before work, and when working, the front upper straightening roller 13 is located at the lower limit of the fitting tolerance of the thread fit under the reaction force of the workpiece, so that there is a certain height difference between the two states, which has a certain impact on the straightening of the workpiece.

[0034] The straightening assembly 1 further includes a drive device 14 for driving the lower straightening roller 12 and / or the upper straightening roller 13 to rotate. Since the height of the lower straightening roller 12 does not change, the drive device 14 is preferably connected to the lower straightening roller 12, that is, the lower straightening roller 12 is directly driven to rotate by the drive device 14. If necessary, a transmission structure can be further provided between the lower straightening roller 12 and the upper straightening roller 13, so that the drive device 14 can drive the lower straightening roller 12 and the upper straightening roller 13 to rotate simultaneously.

[0035] There are two symmetrical straightening components 2 in front of the straightening component 1. Figure 2 The straightening assembly 2 includes a fixed seat 21 and a V-shaped frame 22. The closed end of the V-shaped frame 22 is hinged to the inner end of the fixed seat 21. Both ends of the open end of the V-shaped frame 22 are rotatably connected to a vertically arranged straightening wheel 23. The bottom of the straightening wheel 23 is provided with an expanding diameter retaining edge 24.

[0036] Furthermore, the top surface of the expanding rib 24 and the top of the lower straightening roller 12 are located at the same horizontal plane.

[0037] In this way, the expanded diameter rib 24 can support the bottom surface of the side of the workpiece to prevent the workpiece from sagging, and the straightening wheel 23 can resist the side of the workpiece to prevent the workpiece from shaking left and right. When the straightness of the side of the workpiece is large, the straightening wheel 23 can drive the V-shaped frame 22 to rotate, so that the straightening wheel 23 avoids inward or outward, ensuring that the workpiece can pass smoothly. It should be noted that: since the two straightening components 2 are symmetrically arranged and each straightening component 2 has two straightening wheels 23 spaced apart along the length direction of the workpiece, the distance between the two straightening wheels 23 at the same position in the length direction of the workpiece remains unchanged, that is, the two straightening wheels 23 avoid in the same direction, so it can adapt to the width of the workpiece and will not affect the passage of the workpiece due to the straightening wheel 23 avoiding inward or outward.

[0038] Furthermore, an extension plate 3 extending forward is provided on the front side of the two upright posts 11 , and fixing seats 21 are provided on both left and right sides of the upper surface of the extension plate 3 .

[0039] Example 2, combined with the attached Figure 1-4 , an aluminum plate straightening device, based on the first embodiment, is also provided with two straightening components 2 symmetrically arranged on the left and right behind the straightening component 1; the structure and installation method of the straightening component 2 behind the straightening component 1 can be set with reference to the structure and installation method of the straightening component 2 in front of the straightening component 1, and will not be described in detail here.

[0040] Example 3, combined with the attached Figure 4 , an aluminum plate straightening device, based on embodiment one or two, a horizontal support wheel 4 for supporting the workpiece is provided in the middle of the extension plate 3; this can prevent the middle part of the workpiece from sagging when the width of the workpiece is large.

[0041] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
