A supporting roller is arranged under each pressing roller. Specifically, synchronous transmission connection between the adjacent supporting rollers and between the adjacent pressing rollers is achieved through a chain transmission set I.

According to the design, under the action of a single power source (namely a driving motor), the multiple pressing rollers and the multiple supporting rollers can be synchronously driven to rotate, and therefore it is ensured that an aluminum plate can continuously move rightwards under the action of the device, and it is ensured that the space area needed in the aluminum plate flattening process is relatively small.

Description

Technical Field

[0001] This utility model relates to the technical field of aluminum plate processing equipment, and in particular to an aluminum plate flattening and conveying device. Background Technology

[0002] Aluminum sheet, also known as aluminum plate, is a sheet material with a rectangular cross-section and uniform thickness, produced from pure aluminum or aluminum alloy materials through pressure processing processes such as shearing or sawing.

[0003] In the aluminum sheet processing flow, to ensure that the processing accuracy meets the requirements, the aluminum sheet usually needs to be flattened. According to the national standard for aluminum sheet flatness, the flattening operation should ensure the flatness, length tolerance, diagonal tolerance, and surface quality of the aluminum sheet, and avoid processing defects caused by improper human operation. In the existing technology, most companies use mechanical flattening methods, that is, using mechanical equipment such as pressure rollers and pressure plates to flatten the aluminum sheet. This method applies appropriate pressure to effectively flatten the raised parts of the aluminum sheet surface, thereby achieving a flattening effect. This method is suitable for situations where the aluminum sheet thickness is relatively thin and the flatness requirements are not high, but its requirements for on-site equipment are relatively low.

[0004] It is worth noting that in existing equipment, the pressure rollers set on the upper side of the aluminum plate and the support rollers set on the lower side of the aluminum plate generally do not have spontaneous rotation characteristics (the aluminum plate is flattened by the clamping effect applied by the pressure rollers and support rollers). This is mainly because there are a large number of pressure rollers and support rollers and the rotation direction is difficult to select. Therefore, in general, corresponding push plates or other corresponding thrust devices are set on one side of multiple support rollers to push the aluminum plate between the pressure rollers and support rollers.

[0005] However, in practice, the space occupied by the thrust device itself inevitably means that the flattening process of the aluminum plate requires a relatively large area to complete. Since aluminum plate flattening is an auxiliary process, allocating a large area within the production plant for this operation would be highly uneconomical. Therefore, we believe there is a need for an aluminum plate flattening and conveying device that can spontaneously drive the continuous unidirectional movement of the aluminum plate without requiring an external power source, thus reducing the required space volume. Utility Model Content

[0006] To address the limitations of existing technologies, this invention proposes an aluminum plate flattening and conveying device, which has the advantage of small space occupation and effectively solves the problem that the thrust device in existing technology devices requires a lot of additional space.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An aluminum plate flattening and conveying device includes multiple support rollers arranged equidistantly from left to right along the front and rear axial directions, and multiple pressure rollers arranged equidistantly from left to right along the front and rear axial directions. Each pressure roller has a corresponding support roller on its lower side. A chain drive group I is drivingly connected between adjacent support rollers and between adjacent pressure rollers. The multiple support rollers and multiple pressure rollers rotate synchronously through the chain drive group I. A support frame is provided on the lower side of the multiple support rollers. The support rollers are rotatably connected to the support frame. A drive motor is fixedly connected to the support frame. The output shaft of the drive motor is drivingly connected to one of the pressure rollers and one of the support rollers through two chain drive groups II, respectively.

[0009] Preferably, a synchronization plate is provided at both axial ends of the plurality of pressure rollers, the pressure rollers are rotatably connected to the synchronization plate, and a slide rail is provided on both sides of the synchronization plate, the slide rail is fixedly connected to the support frame, and the synchronization plate moves up and down linearly relative to the support frame.

[0010] Preferably, the upper end of the synchronization plate is provided with a positioning plate, which is fixedly connected to the slide rail on the same side. Furthermore, the positioning plate has a through-hole with an internal thread, and a screw is screwed into the internal thread hole. The screw is rotatably connected to the synchronization plate. A limit rod is fixedly connected to the upper end of the synchronization plate, and a limit hole is provided on the positioning plate for the limit rod, and the limit rod is inserted into the limit hole.

[0011] Preferably, one of the pressure rollers is keyed to a universal joint at its axial end. There are two universal joints, which are arranged along the central axis of the pressure roller. The universal joint located away from the pressure roller is connected to the output shaft of the drive motor, and the two universal joints are connected to each other by a telescopic rod.

[0012] Preferably, a fixing plate is provided on one side of the support frame, the fixing plate has positioning holes, and the fixing plate is rotatably connected to the output shaft of the drive shaft and a universal joint that is relatively away from the pressure roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes the synergistic effect of chain drive group I and chain drive group II to ensure the synchronous rotation of multiple pressure rollers and support rollers under a single power source (i.e., a drive motor). By continuously applying a constant rightward thrust to the aluminum plate, this design ensures stable and continuous rightward movement of the aluminum plate within the device. This method significantly reduces dependence on external power sources while ensuring that the space required for flattening the aluminum plate remains within a small range.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Please see Figure 1 , Figure 2This aluminum plate flattening and conveying device is similar to existing technology, comprising multiple axially arranged support rollers 1, which are evenly distributed from left to right. In practical applications, the aluminum plate is placed above the support rollers 1, with its lower end face in contact with the support rollers 1 to ensure the stability of the aluminum plate during conveying. This design not only ensures the stability of the aluminum plate during conveying but also effectively distributes the weight of the aluminum plate through the even distribution of the support rollers 1, reducing the burden on individual support points and thus extending the service life of the support rollers 1.

[0025] In addition, a support frame 5 is provided below multiple support rollers 1. The support frame 5 is rotatably connected to the support rollers 1. This design provides support for the support rollers 1 and realizes their limiting function. The design of the support frame 5 not only stabilizes the support rollers 1, but also allows the support rollers 1 to cope with various working conditions during operation through flexible rotational connection, thereby comprehensively improving the adaptability and reliability of the device.

[0026] It is worth noting that existing technology devices typically also include multiple axially arranged pressure rollers 2, which are also evenly arranged from left to right. Each pressure roller 2 is cleverly fitted with a support roller 1. As the aluminum sheet passes through them, the combined pressure from both above and below precisely corrects the aluminum sheet, ensuring perfect flatness during the pressing process. This combination of pressure rollers 2 and support rollers 1 effectively eliminates warping and bending that may occur during the conveying process, guaranteeing the flatness and quality of the aluminum sheet.

[0027] It should be noted that in practical applications, pressure roller 2 is usually not equipped with an external power source (while support roller 1 is optional). Pressure roller 2 cleverly utilizes the frictional resistance between itself and the aluminum plate to rotate. As the aluminum plate moves from left to right, the pressure it exerts on the side of pressure roller 2 becomes the driving force for its rotation. This design effectively avoids sliding friction, carefully protecting the surface of the aluminum plate from any damage. This ingenious design utilizes the movement of the aluminum plate itself to drive pressure roller 2, saving energy and improving work efficiency.

[0028] Therefore, as Figure 1 , Figure 3 As shown, unlike existing devices, this device innovatively incorporates a chain drive assembly I7 between adjacent support rollers 1 and pressure rollers 2 to reduce the use of external power sources and ensure a continuous rightward thrust on the aluminum plate during flattening. This design synchronously drives multiple support rollers 1 and pressure rollers 2, ensuring a stable pushing force on the aluminum plate even with limited power sources. This chain drive assembly I7 not only reduces the use of power sources but also ensures the stability and flatness of the aluminum plate during transport through synchronous rotation.

[0029] Specifically, this device has a drive motor 6 fixedly connected to the support frame 5. The output shaft of the drive motor 6 is connected to one of the pressure rollers 2 and one of the support rollers 1 via two chain drive groups II 4, thereby achieving synchronous rotation of multiple pressure rollers 2 and multiple support rollers 1 with a single power source. Furthermore, the drive motor 6 is cleverly placed inside the support frame 5. This design not only saves a lot of space but also significantly reduces the device's dependence on its installation position. This design of the drive motor 6 not only saves space but also makes the entire device more compact, facilitating maintenance and operation.

[0030] Furthermore, to accommodate aluminum plates of different sizes, this device is designed with a sliding connection between the pressure roller 2 and the support frame 5. This sliding connection design allows the pressure roller 2 to be flexibly adjusted according to the width of the aluminum plate, a feature that significantly enhances the versatility and adaptability of the device.

[0031] Therefore, please refer to Figure 3 , Figure 6 To ensure that the multiple pressure rollers 2 remain on the same horizontal line and that the aluminum plate receives stable pressure during its continuous rightward movement, a synchronization plate 11 is installed at both ends of each pressure roller 2. The pressure rollers 2 are rotatably connected to the synchronization plates 11, ensuring that all pressure rollers 2 remain on the same horizontal line. This design of the synchronization plates 11 ensures the stability of the pressure rollers 2 during operation, preventing tilting of the pressure rollers 2 due to uneven aluminum plate thickness, thereby ensuring the flatness of the aluminum plate.

[0032] Furthermore, slide rails 13 are respectively provided on both sides of the synchronization plate 11. The position of the slide rails 13 is fixed by constraining the fixed connection between the slide rails 13 and the support frame 5. The slide rails 13 allow the synchronization plate 11 to move linearly up and down only relative to the support frame 5, so as to adapt to aluminum plates of different thicknesses. The design of the slide rails 13 ensures the stable movement of the synchronization plate 11, while limiting its range of motion, effectively preventing accidental rotation of the synchronization plate 11, thereby ensuring the flatness of the aluminum plate.

[0033] It should be noted that the surface contact between the slide rail 13 and the synchronous plate 11 can constrain the position of the synchronous plate 11, prevent the synchronous plate 11 from rotating, and ensure that the upper surface of the synchronous plate 11 is always in a horizontal state. This surface contact design effectively improves the positioning accuracy of the synchronous plate 11 and ensures the stability of the aluminum plate during the conveying process.

[0034] In addition, a positioning plate 10 is provided on the upper end of the synchronization plate 11. The positioning plate 10 is fixedly connected to the slide rail 13 on the same side to ensure the precise positioning of the synchronization plate 11. The design of the positioning plate 10 further improves the positioning accuracy of the synchronization plate 11, and the firm connection with the slide rail 13 enhances the stability of the synchronization plate 11, thereby improving the working efficiency of the entire device.

[0035] Meanwhile, a threaded hole is drilled through the positioning plate 10, into which a screw 12 is screwed. The screw 12 is rotatably connected to the synchronization plate 11. Adjusting the screw 12 allows for fine-tuning of the position of the synchronization plate 11, thereby precisely controlling the height of the pressure roller 2. A limit rod 9 is fixed to the upper end of the synchronization plate 11, and a corresponding limit hole is provided on the positioning plate 10. The limit rod 9 is inserted into the limit hole, thus restricting the synchronization plate 11 to only perform vertical linear movement and preventing it from rotating around the screw 12. The fine-tuning and limit design ensures that the device can accurately control the height of the pressure roller 2, thereby ensuring the flatness of the aluminum plate.

[0036] It should be noted that in existing technical devices, the chain drive assembly II4 itself has a certain adjustment capability. It can change the horizontal projection length by adding an auxiliary constraint wheel (synchronously changing the vertical projection length), or change the vertical projection length by adding or removing chain links. However, these methods require professional personnel to operate and adjust for a long time, which is quite cumbersome. Although this adjustment method can achieve a certain adjustment function, it is complex to operate and inefficient.

[0037] Therefore, please refer to Figure 4 , Figure 5 This device features two universal joints 14 keyed to the axial end of one of the pressure rollers 2. These two universal joints 14 are arranged along the central axis of the pressure roller 2, with the universal joint 14 furthest from the pressure roller 2 connected to the output shaft of the drive motor 6. This design of the universal joints 14 allows the pressure roller 2 to accommodate aluminum plates at different angles, while maintaining the transmission connection between the output shaft of the drive motor 6 and the pressure roller 2 without altering the chain drive assembly II 4. The design of the universal joints 14 not only improves the adaptability of the device but also ensures the stability and reliability of the transmission through its flexible connection method.

[0038] Specifically, the two universal joints 14 are connected by a telescopic rod 8, allowing the pressure roller 2 to flexibly adapt to aluminum plates at multiple angles. This also ensures a smooth connection between the output shaft of the drive motor 6 and the pressure roller 2, eliminating the need to adjust the chain drive assembly II 4. The telescopic rod 8 design enhances the adaptability of the device, and its flexible connection ensures stable and reliable transmission.

[0039] It is worth noting that in practical applications, the telescopic rod 8 is generally composed of an inner rod and a sleeve nested together, which will not be elaborated here. However, in order to ensure that the two universal joints 14 are connected by transmission through the telescopic rod 8, it is necessary to avoid the inner rod and sleeve contained in the telescopic rod 8 being only keyed and slidably connected.

[0040] It should be emphasized that, to ensure that the chain drive assembly II4 requires no adjustment, a fixed plate 3 is provided on the side of the support frame 5, which is rotatably connected to the output shaft of the drive shaft and the universal joint 14 away from the pressure roller 2, ensuring the overall stability and reliability of the device. The design of the fixed plate 3 improves the stability of the device, and the rotatable connection enhances reliability, ensuring smooth conveying of the aluminum plate.

[0041] It should be noted that in practical applications, the fixing plate 3 is provided with positioning holes 15. Therefore, positioning pins or screws can be inserted into the positioning holes 15 to constrain the position of the fixing plate 3, and the fixing plate 3 can determine its fixed position according to the surrounding environment. This positioning hole 15 design not only improves the positioning accuracy of the fixing plate 3, but also further strengthens the stability of the fixing plate 3 through its synergistic effect with the positioning pins or screws, thereby improving the operating efficiency of the entire device.

[0042] In practical applications, this utility model is as follows:

[0043] First, the operator uses the corresponding wrench to rotate the screw 12 to precisely adjust the height of each pressure roller 2 to ensure that the distance between the pressure roller 2 and the support roller 1 meets the actual requirements;

[0044] Subsequently, the operator started the drive motor 6, so that under the coordinated action of the chain drive group I7 and the chain drive group II4, the multiple support rollers 1 and the multiple pressure rollers 2 could rotate synchronously;

[0045] Finally, the operator carefully places the aluminum plate onto support roller 1 and skillfully guides the end of the aluminum plate into the gap between the leftmost support roller 1 and pressure roller 2. During this process, as pressure roller 2 and support roller 1 rotate synchronously, the aluminum plate is drawn between pressure roller 2 and support roller 1 by friction and continuously experiences a rightward thrust, causing the aluminum plate to move continuously to the right. At the same time, the aluminum plate is continuously subjected to pressing forces in both the upper and lower directions.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
