[0003] In the production process of aluminium sheet, in order to ensure the continuity of the processing process, the aluminium ingot is usually wound into an aluminium roll after being pressed thin. This form of aluminium roll has a significant advantage in storage space, and can greatly save space compared to the original aluminium ingot. However, even if the aluminium sheet exists in the form of sheet, it may still be distorted due to external environmental interference in the storage and transportation process.

DETAILED DESCRIPTION

[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range of the utility model protection.

[0025] In the description of the utility model, it is understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model.

[0026] Please refer to Figure 1 , Figure 2 An aluminum plate flattening device, the structural design of the technical device is consistent with the existing technical device, it is composed of two front and rear arranged support frames, the support frames serve as bearing bases. In practical application, the form and specification of the support frame can be flexibly selected according to the requirements, and various scenes can be adapted. The main function of the support frame 1 is to provide necessary support for other components of the device.

[0027] A plurality of support rollers 2 are arranged in sequence from left to right at the upper end portion of the support frame 1, and the support rollers 2 are rotatably connected with the support frame 1. The design limits the position of the support roller through the support frame, ensures that the aluminum plate is stably supported, and realizes smooth movement from left to right.

[0028] In addition, in the prior art device, in order to realize the flattening of the aluminum plate, a plurality of pressure rollers 3 are also arranged from left to right above the support rollers 2. Each pressure roller cooperates with the corresponding support roller above and below, applies clamping force through synergistic effect, corrects the aluminum plate, and completes the flattening operation.

[0029] Therefore, in the prior art device, the distance between the pressure roller 3 and the support roller 2 must be accurately set to ensure that the aluminum plate can smoothly enter between the pressure roller 3 and the support roller 2, and at the same time, the pressure roller 3 and the support roller 2 can exert sufficient clamping force on the aluminum plate to realize effective flattening.

[0030] Please refer to Figure 1 , Figure 3 , Figure 5 The device also includes a slide rail 4, a plurality of sliding grooves 17 are provided on the slide rail 4 in front and rear, and the sliding grooves 17 correspond to a plurality of pressure rollers 3. Each pressure roller is embedded in the corresponding sliding groove, and by means of the design of the sliding groove, the pressure roller can move linearly in the upward and downward directions, thereby effectively adjusting the distance between the pressure roller and the support roller.

[0031] In addition, the device is provided with a positioning block 12 in each of the sliding grooves 17, and the positioning block 12 is rotatably connected with the axial end of the corresponding pressure roller 3. The close cooperation between the positioning block and the sliding groove ensures that the pressure roller and the support roller are aligned upward and downward, and the pressure roller can only move linearly in the upward and downward directions.

[0032] Further, the device is fixedly connected with left and right axial positioning shafts 16 on the left and right sides of each positioning block 12, and a limiting groove 18 is arranged in the slide rail 4 for the positioning shaft 16. The positioning shaft is inserted into the limiting groove, effectively fixing the horizontal position of the compression roller, so that it can only move up and down in a straight line, thereby enhancing the stability and flattening performance of the compression roller.

[0033] It is worth noting that in actual application, the structural features of the positioning shaft 16 can ensure that the limiting effect is achieved while further reducing the frictional resistance of the compression roller 3 during the upward and downward sliding process, which helps to reduce frictional loss and thus prolong the service life of the device.

[0034] Further, the device restricts the number of slide rails 4 to two, which are located at the two axial ends of the compression roller 3. At this time, the two slide rails 4 are fixedly connected with the support frame 1, so that the positioning blocks 12 inside the two slide rails 4 can work cooperatively to effectively constrain the position of the two axial ends of the compression roller 3, ensuring that the compression roller 3 will not be unbalanced due to unilateral stress.

[0035] Specifically, the compression roller 3 is rotationally connected with the positioning block 12 by means of the bearing 13, which effectively reduces the frictional resistance of the compression roller 3 during rotation, thereby prolonging the overall service life of the device.

[0036] Please refer to Figure 4 , Figure 5 , Figure 6 In detail, in order to ensure that the aluminum plate can be smoothly inserted between the compression roller 3 and the support roller 2 in actual application, the device is fixedly installed with a compression spring 15 on each positioning block 12.

[0037] A pressing plate 14 is installed at the top end of the compression spring 15, and the two ends of the compression spring 15 are firmly connected with the positioning block 12 and the pressing plate 14, respectively. Under this configuration, in cooperation with the height limiting mechanism arranged on the upper end of the pressing plate 14, the position of the pressing plate 14 can be kept stable while the compression roller 3 is given sufficient downward pressure by the compression spring 15, and the height of the compression roller 3 can be adjusted accordingly. This mechanism enables the compression roller 3 to convert the horizontal thrust of the aluminum plate into a vertical thrust by virtue of its own structure, to resist the downward pressure exerted by the compression spring 15, ensuring that the compression roller 3 can move upward, so that the aluminum plate can be smoothly inserted between the compression roller 3 and the support roller 2.

[0038] In addition, it needs to be particularly emphasized that in order to ensure that the compression roller 3 and the support roller 2 provide sufficient downward pressure to the aluminum plate to achieve sufficient flattening, the device is designed with multiple pressing plates 14, and the height of the upper end face of the pressing plates 14 is gradually decreased from left to right through the height adjusting mechanism. This design makes the aluminum plate gradually increase the pressure it bears during the movement from left to right.

[0039] In actual operation, at least one of the pressure rollers 3 or the support rollers 2 can rotate automatically to drive the aluminum plate to move from left to right. Therefore, in actual operation, as the aluminum plate moves from left to right, the number of pressure rollers 3 or support rollers 2 that the aluminum plate simultaneously contacts gradually increases, and the number of rightward pushing forces that the aluminum plate receives also increases. At the same time, in actual operation, the automatic rotation of the pressure rollers 3 or the support rollers 2 drives the aluminum plate to move linearly through friction, so the greater the compression force provided by the pressure rollers 3 or the support rollers 2 to the aluminum plate, the more closely the aluminum plate contacts the pressure rollers 3 or the support rollers 2, and the greater the rightward pushing force that the aluminum plate receives through friction. This design can ensure that the greater the horizontal pushing force that the aluminum plate exerts on the pressure roller 3 located to the right of the aluminum plate during the movement of the aluminum plate to the right, the greater the downward pressure that the rightward pressure roller 3 bears under the compression spring 15, thereby ensuring smooth movement of the aluminum plate to the right and gradually increasing the compression force on the aluminum plate, thereby ensuring that the aluminum plate can be fully flattened.

[0040] Therefore, as shown in Figure 2 , in actual application, the device uses a synchronous chain set for transmission connection between adjacent two support rollers, and a driving motor is fixedly installed on the lower side of the support frame. The output shaft of the motor is connected with the support roller. Through the operation of the driving motor, the support roller is driven to rotate, thereby realizing the rotation function of the support roller.

[0041] Further, as shown in Figure 4 , adjacent two pressure rollers are also connected by a synchronous chain set for transmission connection, which ensures that when any pressure roller rotates, it can drive other pressure rollers to rotate synchronously. This design not only improves the fault tolerance of the device, but also increases the horizontal pushing force that the aluminum plate can bear, effectively avoiding the phenomenon that the aluminum plate is stuck between the pressure rollers and the support rollers.

[0042] Please refer to Figure 3 and Figure 6 . Specifically, the height limiting mechanism includes a limiting frame 7, the upper end of the limiting frame 7 is fixedly connected with a screw rod II 8, and a follower plate 10 is provided at the upper ends of the plurality of limiting frames 7. The follower plate 10 has a plurality of through holes II on the left and right sides for the plurality of screw rods II 8, and the screw rod II 8 is inserted into the through hole II.

[0043] On this basis, a limiting nut is arranged at the upper end of the screw rod II and is screwed with the screw rod II. When the compression spring provides an upward pushing force to the limiting frame, the limiting nut can be used to fix the limiting frame by keeping the height of the follower plate unchanged, thereby achieving the expected technical effect.

[0044] Further, the device stipulates that each limiting frame 7 is in U-shaped structure in the vertical plane projection, so that each slide rail 4 can be stably inserted into the U-shaped opening of the corresponding limiting frame 7, and through the constraint of the slide rail 4, the limiting frame 7 is fixed, ensuring that the operator can easily adjust the position of the limiting nut 19 with one hand during actual operation.

[0045] It should be noted that, as shown in Figure 3 , the front end of the pressing plate 14 protrudes out of the slide groove 17, and the lower end of the limiting frame 7 has a wide horizontal surface, which can ensure that the limiting frame 7 and the pressing plate 14 have a large contact area, and the pressing plate 14 will not be subjected to unilateral force, which can fully ensure that the compression spring 15 can provide a downward pressure on the positioning block 12.

[0046] It is particularly noteworthy that, since the device uses the follower plate 10 to cooperate with the limiting nut 19 to jointly control the height of the multiple limiting frames 7 in actual use, and the height of the limiting frame 7 is directly related to the downward pressure on the compression roller 3, when different thicknesses of aluminum plates need to be processed, the height of the limiting frame 7 can be easily adjusted by adjusting the height of the follower plate 10, thereby ensuring that the device can apply gradually increasing compression force to aluminum plates of different thicknesses, achieving the ideal technical effect.

[0047] In addition, in actual application, the presence of the limiting nut 19 allows the height of the single limiting frame 7 to be adjusted individually, which can achieve the adjustment of the intensity of the compression force applied by the compression roller 3 and the corresponding support roller 2 on the aluminum plate from left to right.

[0048] Please refer to Figure 5 and Figure 6 , specifically, in order to adjust the height of the follower plate 10, the device is particularly provided with a fixed plate 9 between the two slide rails 4, and the upper end of the fixed plate 9 is firmly connected with the screw rod I 11. A through hole I 120 is designed on the follower plate 10, which is vertically aligned with the screw rod I 11, ensuring that the screw rod I 11 can accurately pass through and be embedded therein.

[0049] Under this configuration, the limiting nut 19 provided on the upper end of the follower plate 10 and threaded with the screw rod I 11 can accurately adjust the height of the follower plate 10.

[0050] In the actual application process of the device:

[0051] First, the operator needs to place the aluminum plate stably on the left side of the support frame 1, ensuring that the aluminum plate is in close contact with the support roller 2. At this stage, the driving motor 6 is started, so that the multiple support rollers 2 rotate synchronously, and the aluminum plate is affected by the right movement of the support roller 2.

[0052] Subsequently, as the aluminum plate moves to the right, the right end of the aluminum plate is in contact with the leftmost compression roller 3 and the support roller 2 below it on both the top and bottom sides. At this time, the aluminum plate continues to be pushed to the right by the support roller 2, causing the aluminum plate to be clamped between the leftmost compression roller 3 and the support roller 2 below it. In this process, the leftmost compression roller 3 moves upward and drives the multiple compression rollers 3 to rotate synchronously as the aluminum plate moves to the right;

[0053] Next, as the aluminum plate continues to move to the right, the number of compression rollers 3 in contact with the aluminum plate gradually increases. At this time, the rightward pushing force on the aluminum plate gradually increases as the movement to the right continues, and the number of upward and downward pressing points on the aluminum plate also gradually increases, gradually improving the smoothness of the aluminum plate itself;

[0054] Finally, the left end of the aluminum plate is disengaged from the rightmost compression roller 3, and the flattening process of the aluminum plate is complete.

[0055] Although embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application. The scope of the present application is defined by the appended claims and their equivalents.
