Description

Technical Field

[0001] This invention relates to the field of overhead conveyor technology, and more specifically to a conveyor for aluminum processing. Background Technology

[0002] During the processes of spraying, cleaning, drying, curing, and other surface treatments, aluminum materials typically require continuous transfer between different processing stations using a conveying device. For longer aluminum profiles, a suspended conveying structure is generally used, where vertically extending hanging rods are connected to the conveyor chain or track walking mechanism, and multiple support rods are set at vertical intervals on the hanging rods to provide layered support for the aluminum profiles, keeping them suspended during the conveying process.

[0003] For example, Chinese Patent No. CN207605915U discloses a long strip aluminum profile painting and conveying device, which includes a conveying track, conveying rollers, a drive chain, a drive sprocket, and an aluminum profile hanging rod; the conveying track includes a lower supporting track and a clamping upper track that are parallel to each other, the conveying rollers include a clamping roller and a moving roller shaft, one end of the moving roller shaft is provided with a suspension hanging ring, and the other end is fixedly connected to the drive chain; the upper end of the aluminum profile hanging rod is provided with a suspension hook, and an aluminum profile support plate is provided on the aluminum profile hanging rod, with the side of the aluminum profile support plate closer to the aluminum profile hanging rod lower than its loading side, so as to support and convey the long strip aluminum profile.

[0004] Since each conveying roller is fixedly connected to a different node of the drive chain, the spacing between each aluminum profile hanger is the path distance of the corresponding chain node along the conveying track. When adjacent conveying rollers enter the curved track one after another, although the path distance between the chain nodes remains unchanged, the straight-line distance between the two aluminum profile hangers will decrease as the track bends. Furthermore, the orientation of the two aluminum profile hangers changes with the track direction at their respective positions, causing the aluminum profile spanning between the two aluminum profile hangers to slip or deviate relative to the aluminum support plate.

[0005] When aluminum profiles deviate, their end positions and lateral sweep range during transport change. When entering processing stations such as spraying chambers, cleaning chambers, drying ovens, or curing ovens, they are prone to approaching or contacting the station's entrance edge and internal structure. To accommodate the potential deviation of aluminum profiles after bending, the inlets and outlets of related processing equipment typically require larger passageways, increasing the difficulty of equipment opening size, sealing, insulation, and spatial arrangement. Simultaneously, as the aluminum profile slides relative to the aluminum pallet, its support position may gradually approach the free end of the pallet, reducing the effective support length. Under the combined effects of transport vibration, start-stop inertia, or bending impacts, the aluminum profile may further shift, jump upwards, or even detach from the pallet, affecting the transport stability and safety during continuous aluminum profile processing. Summary of the Invention

[0017] By adopting the above technical solution, the technical effects achieved by this invention compared to the prior art are as follows: 1. This invention enables two support positions that jointly support the same group of aluminum materials to maintain a relatively stable spatial straight-line distance when passing through a curved conveying area. This reduces the slippage, skewing, and changes in support position of the aluminum materials caused by the two support positions moving closer or further apart. As a result, it improves the stability of continuous conveying of long strip aluminum materials in straight and curved areas and reduces the need for additional throughput allowance at the inlet and outlet of the processing equipment.

[0018] 2. The present invention can constrain the relative orientation of two support positions in the same group, so that the two maintain a basically consistent support direction during the conveying process, reduce the torsion, pushing and lateral movement of the aluminum material caused by the different support directions of the two places, and make the aluminum material maintain a relatively stable posture when passing through curves and when switching between straight and curved conveying areas.

[0019] 3. The present invention can switch between traction and following states according to the needs of supporting groups, and make the traction relationship change accordingly with the rotation state, reducing the structural differences of the required components on the active and driven sides, facilitating the configuration, adjustment, replacement and maintenance of the suspension position, and reducing the possibility of incomplete state switching or incorrect correspondence affecting the conveying operation.

[0020] 4. This invention can limit the lateral deviation and upward movement during the movement of aluminum materials while bearing the vertical load of the aluminum material. It reduces the lateral action of curves, the attitude deviation caused by track joints and running vibration, abnormal friction and local wear, and reduces the possibility of the walking components getting stuck or going out of the normal operating position.

[0021] 5. This invention can adjust and stably maintain the support spacing according to the length of the aluminum material and the support requirements, expanding the range of adaptability to aluminum materials of different specifications; when the aluminum material deviates from the normal support position, it can also gradually guide its movement direction and form a return trend, while buffering the fall contact, suppressing small fluctuations near the normal support position, and forming an end limit when abnormally moving outward, thereby reducing the risk of the aluminum material leaving the support area.

[0025] The present invention will be further described in detail below with reference to the embodiments.

[0026] Example 1 like Figures 1-9 As shown, the present invention provides a conveying device for aluminum processing, including a frame 1; a conveying track 2 disposed on the frame 1; a traction assembly including a traction chain 3 arranged along the conveying track 2 and a drive mechanism for driving the traction chain 3; a plurality of traveling assemblies 6, each moving and cooperating with the conveying track 2; a plurality of suspension assemblies 5, each connected to a corresponding traveling assembly 6; a plurality of supporting assemblies 4, each connected to a corresponding suspension assembly 5, for supporting aluminum materials; a plurality of connecting assemblies 7; the plurality of suspension assemblies 5 are arranged in groups along the conveying track 2, each group including two adjacent suspension assemblies 5, and connected to two other suspension assemblies in the same group. The two supporting components 4 connected to the suspension component 5 jointly support the aluminum material in the same group; the traction component is driven to one of the suspension components 5 in each group, and drives the corresponding walking component 6 to move through the suspension component 5; each connecting component 7 connects two suspension components 5 in the same group, the connecting component 7 has a preset connection length and can transmit tension and pressure, and is used to transmit the movement of the suspension component 5 driven to the other suspension component 5 in the same group, and the other suspension component 5 drives the corresponding walking component 6 to move, so as to limit the spatial linear distance between the two suspension components 5 in the same group.

[0027] In this embodiment, by having only one of the two suspension components 5 that jointly support the same group of aluminum materials directly receive the drive of the traction component, while the other suspension component 5 moves with the former through the connecting component 7, the connecting component 7 can transmit tension and pressure between the two suspension components 5 and limit the linear distance between them.

[0028] When the two walking components 6 pass through the curved conveying path, the walking component 6, which is not directly connected to the traction component, is no longer constrained by the position of the other fixed chain node. Instead, it moves accordingly along the conveying track 2 under the drive of the connecting component 7. This reduces the change in the straight-line distance between the two suspension components 5, reduces the possibility of significant slippage or tilting of the aluminum material relative to the supporting component 4, and keeps the supporting position of the aluminum material relatively stable.

[0029] During operation, according to the length of the aluminum material to be conveyed and the support requirements, two suspension components 5 arranged adjacent to each other along the conveying track 2 are divided into a group, and the aluminum material in the same group is supported by the support components 4 connected to the two suspension components 5 respectively. The two suspension components 5 move along the conveying track 2 with the corresponding walking components 6 respectively, and the connecting components 7 connect the two suspension components 5 in the same group. When the traction assembly is running, the traction chain 3 directly drives one of the suspension components 5 in the same group, and through the suspension component 5, drives the corresponding walking component 6 to move along the conveying track 2; the suspension component 5 drives another suspension component 5 in the same group and its corresponding walking component 6 to move through the connecting component 7, so that the two supporting components 4 jointly convey aluminum material along the conveying track 2. Within the linear conveying area, the two traveling components 6 in the same group move in the same conveying direction. The connecting component 7 maintains its preset connection length and transmits traction between the two suspension components 5, so that the two supporting components 4 jointly support the aluminum material with a relatively stable spacing. When two traveling components 6 in the same group enter the curved conveying area one after another, the suspension component 5, which is directly connected to the traction chain 3, continues to drive the corresponding traveling component 6 to move along the conveying track 2. The other suspension component 5 and its corresponding traveling component 6 are not directly connected to another fixed node on the traction chain 3, but are driven to move by the connecting component 7. As the two traveling components 6 pass through the curved conveying area, the connecting component 7 bears tension or pressure depending on the relative position between the two suspension components 5. When the two suspension components 5 tend to move away from each other, the connecting component 7 transmits tension to the rear suspension component 5; when the two suspension components 5 tend to move closer to each other, the connecting component 7 transmits pressure between them, thereby limiting the change in the linear spatial distance between the two suspension components 5. Since the other traveling component 6 can adjust its position along the conveying track 2 under the constraint of the connecting component 7, its moving position is no longer determined solely by another fixed node on the traction chain 3. The spatial distance between the two supporting components 4 is constrained by the connecting component 7, which can reduce the extent to which the two supporting positions at the bends approach or move too far apart, thereby reducing the possibility of significant movement and skew of the aluminum material straddling the two supporting components 4. When the two traveling components 6 in the same group leave the curved conveying area and enter the subsequent straight conveying area, the connecting component 7 continues to drive the traveling components 6 that are not directly connected to the traction chain 3 to follow, so that the two supporting components 4 return to the relative position adapted to the straight conveying path and continue to jointly support the aluminum material for conveying.

[0030] The drive mechanism includes a drive motor, a reducer, and a drive sprocket. The output end of the drive motor is connected to the drive sprocket via the reducer. The traction chain 3 meshes with the drive sprocket and is wound around the drive sprocket and several driven sprockets arranged along the conveying route to form a circular conveying path arranged along the conveying track 2. Since chain conveying drive is a relatively mature conventional structure, and this drive is not the main innovation in this case, it is not described in detail.

[0031] Example 2 like Figures 1-9 As shown, based on Embodiment 1, the present invention provides a technical solution: preferably, each of the suspension components 5 includes a suspension frame 501 connected to the corresponding walking component 6 and a rotating part 502 rotatably connected to the suspension frame 501 about a vertical axis, and the supporting component 4 is connected to the corresponding rotating part 502. The connecting component 7 includes two connecting rods spaced apart in the horizontal direction. The two ends of the two connecting rods are respectively hinged to the rotating parts 502 of the two suspension components 5 in the same group through vertical hinge shafts. The two connecting rods and the two rotating parts 502 in the same group form a parallelogram linkage mechanism in the top view. Among the two suspension components 5 in the same group, the rotating part 502 of the suspension component 5 that is connected to the traction component is in a rotationally locked state relative to the corresponding suspension frame 501, and the rotating part 502 of the other suspension component 5 is in a rotationally released state relative to the corresponding suspension frame 501.

[0032] Even after the spatial distance between the two suspension components 5 in the same group is limited, the two support components 4 may still deflect according to the track direction of the corresponding walking component 6. Especially when the two walking components 6 enter the curved conveying area one after the other, the two support components 4 are prone to forming a relative angle, resulting in inconsistent support directions of the aluminum material at two points.

[0033] In this embodiment, while maintaining the spatial distance between the two support positions, the relative orientation of the two support components 4 can be further constrained, so that the two support components 4 maintain a basically consistent support direction during the conveying process. When passing through the curved conveying area, the two support components 4 can perform coordinated posture changes, reducing the directional differences caused by their independent deflection with the corresponding walking components 6. This reduces the possibility of the long strip aluminum material twisting, lateral movement, or local support position changes due to inconsistent support directions at two locations, so that the aluminum material maintains a relatively stable support state when switching between the straight conveying area and the curved conveying area.

[0034] During operation, one side of the two suspension components 5 in the same group that is connected to the traction component is designated as the traction side and kept in rotation lock; the other side is designated as the following side and its degree of freedom of rotation around the vertical axis is released. The traction side thus forms a relatively definite directional reference, while the following side can adjust its orientation according to the constraints of the two connecting rods. Within the linear conveying area, the traction side moves along the conveying track 2 and drives the accompanying side to move via two connecting rods. At this time, the two connecting rods restrict the orientation of the accompanying side, keeping it basically parallel to the traction side, and the two supporting components 4 support the aluminum material together in basically the same direction; When the traction side enters the curved conveying area first while the following side remains in the straight conveying area, the track orientation of the two traveling components 6 begins to differ. The traction side remains locked in rotation, while the following side rotates accordingly around the vertical axis under the drive of the two connecting rods, adjusting its orientation toward the following traction side, rather than changing independently according to the track orientation of its position. As the two traveling components 6 continue to pass through the curved conveying area, the two connecting rods, while maintaining the spatial distance between the two suspension positions, continuously limit the relative angle between the two suspension components 5, keeping the two supporting components 4 basically parallel. As a result, the posture changes of the aluminum material at the two supporting positions tend to be consistent, reducing the torsion or pushing of the aluminum material caused by the different supporting directions at both ends; When the two traveling components 6 leave the curved conveying area in sequence and enter the subsequent straight conveying area, the following side rotates accordingly under the drive of the two connecting rods until the two supporting components 4 return to the relative orientation adapted to the straight conveying. During operation, the traction side remains rotated and locked to provide a directional reference; the traveling side remains rotated and released to accommodate positional changes between the two traveling components 6 when cornering. This coordination prevents the two supporting components 4 from rotating freely on their own, and also prevents interference between them due to different track directions after both sides are locked.

[0035] like Figure 5 , Figure 6 and Figure 7 As shown, preferably, a switching plate 503 is slidably connected to the suspension frame 501 along the vertical direction. A wing plate 506 is fixedly connected to one side of the switching plate 503, and a positioning rod 509 is fixedly connected to the bottom of the wing plate 506. The rotating part 502 includes a turntable rotatably connected to the bottom of the suspension frame 501 about a vertical axis. An ear plate 507 is fixedly connected to one side of the turntable, and an insertion hole 508 corresponding to the positioning rod 509 is provided on the ear plate 507. A transmission plate 504 is fixedly connected to the bottom of the switching plate 503, and the traction chain 3 has intervals along its extension direction corresponding to the transmission plate 504. The corresponding slots 505 (opened on each link of the chain); the transmission plate 504 and the wing plate 506 are respectively provided with positioning holes 512 arranged coaxially in the horizontal direction; the suspension frame 501 is provided with active stop holes 511 and driven stop holes 510 spaced apart in the vertical direction, and the active stop holes 511 and driven stop holes 510 can be coaxially corresponding to the two positioning holes 512; the suspension assembly 5 also includes a pin 513, which selectively passes through the active stop hole 511 or the driven stop hole 510 and the two positioning holes 512 to hold the switching plate 503 in the corresponding position.

[0036] When different suspension components 5 are used on the active and driven sides, it is easy to increase the variety of parts and the difficulty of assembly and maintenance; and when the traction connection state and the rotation lock state are adjusted separately, there may be a mismatch between the two, which may cause the suspension component 5 to be in an incomplete working state.

[0037] In this embodiment, the same type of suspension assembly 5 can select the corresponding working state according to the installation position and support group requirements, thereby reducing the structural differences between the active and driven sides and facilitating the configuration, replacement, and maintenance of the suspension assembly 5 at different chain nodes. When the suspension assembly 5 switches working states, the traction connection state and the rotation lock state can change synchronously, so that the active state corresponds to traction connection and rotation lock, and the driven state corresponds to release of traction connection and release of rotation, reducing the situation where the two states are inconsistent and affect normal transportation. At the same time, the two preset positions can confirm and maintain the working position after switching, reducing the possibility that the suspension assembly 5 will change its working state on its own under the action of running vibration, and keeping the active and driven cooperation relationship between the suspension assemblies 5 in the same group stable.

[0038] When the pin 513 passes through the active stop hole 511 and the two positioning holes 512, the transmission plate 504 is inserted into the corresponding slot 505, and the positioning rod 509 is inserted into the corresponding socket 508; when the pin 513 passes through the driven stop hole 510 and the two positioning holes 512, the transmission plate 504 is withdrawn from the slot 505, and the positioning rod 509 is withdrawn from the socket 508.

[0039] When assembling or adjusting the support groups of the equipment, according to the role of each suspension component 5 in the same group, one suspension component 5 is switched to the active position, and another suspension component 5 is switched to the driven position. The state switching is performed when the traction chain 3 stops running or when the suspension component 5 is not under significant traction load. When switching the suspension component 5 to the active position, first pull out the pin 513 to release the position restriction on the switching plate 503, and then move the switching plate 503 vertically. During the movement of the switching plate 503, the transmission plate 504 and the positioning rod 509 move synchronously to their corresponding mating positions. When the switching plate 503 reaches the active position, the transmission plate 504 enters the slot 505 of the corresponding position on the traction chain 3, and the positioning rod 509 simultaneously enters the insertion hole 508. Subsequently, the pin 513 passes through the active position hole 511 and the two positioning holes 512 to hold the switching plate 503 in the active position. When the traction chain 3 is running, its movement is transmitted to the suspension assembly 5 and the corresponding traveling assembly 6 via the transmission plate 504, causing the suspension assembly 5 to move along the conveyor track 2 as the traction side. At the same time, the positioning rod 509 restricts the rotation of the turntable relative to the suspension frame 501, so that the suspension assembly 5 can provide a directional reference for another suspension assembly 5 in the same group; When the suspension assembly 5 is switched to the driven position, the pin 513 is pulled out, and the switching plate 503 is moved in the opposite direction. The transmission plate 504 is disengaged from the slot 505 of the traction chain 3 along with the switching plate 503, and the positioning rod 509 is disengaged from the insertion hole 508 on the ear plate 507. When the switching plate 503 reaches the driven position, the pin 513 passes through the driven position hole 510 and the two positioning holes 512 to hold the switching plate 503 in the driven position. At this time, the suspension assembly 5 is no longer directly driven by the traction chain 3, but is moved by the traction side of the same group through the connecting assembly 7; the turntable regains its freedom of rotation about the vertical axis and can adjust its orientation under the constraint of the two connecting rods; Since the transmission plate 504 and the positioning rod 509 move synchronously with the switching plate 503, when the suspension assembly 5 switches from the driven position to the driving position, it simultaneously establishes a traction relationship and a rotation lock relationship; when it switches from the driving position to the driven position, it simultaneously releases the above two relationships, thereby avoiding the situation where only one of the switching is completed when adjusting separately; After the switch is completed, pin 513 holds switch plate 503 in the corresponding position. When it is necessary to adjust the position of the active and driven sides, the above operation can be repeated without replacing the entire suspension assembly 5.

[0040] Example 3 like Figure 5 , Figure 6 and Figure 7 As shown, based on Embodiment 2, the present invention provides a technical solution: Preferably, the conveying track 2 includes a web 202 and an upper flange 201 and a lower flange 203 respectively connected to the upper and lower sides of the web 202, and the cross-section of the conveying track 2 is I-shaped; the traveling assembly 6 includes a wheel frame and load-bearing wheels 601, lateral guide wheels 602 and anti-detachment wheels 603 rotatably mounted on the wheel frame; two load-bearing wheels 601 are provided, and the two load-bearing wheels 601 are respectively located on both sides of the web 202, and The two load-bearing wheels 601 roll and abut against the upper surfaces of the lower flange 203 on both sides of the web 202, respectively; two lateral guide wheels 602 are provided, and the two lateral guide wheels 602 are respectively located on both sides of the web 202. The rotation axis of the lateral guide wheels 602 is arranged in the vertical direction, and the two lateral guide wheels 602 roll and cooperate with the two sides of the web 202, respectively; the anti-detachment wheel 603 is located below the lower flange 203 and rolls and cooperates with the lower surface of the lower flange 203.

[0041] When the traveling component 6 is subjected to lateral forces transmitted by the connecting component 7 in the curved conveying area, it is prone to lateral displacement or attitude deviation relative to the conveying track 2; when passing through track joints, starting and stopping, or when vibration occurs, it may also move upward, affecting the operational stability of the traveling component 6.

[0042] In this embodiment, corresponding rolling supports or limits can be formed for the bearing direction, lateral direction and upward movement direction of the walking component 6, so that the walking component 6 maintains a relatively stable running posture when moving along the conveying track 2; in the curved conveying area, the lateral offset and deflection caused by lateral action can be reduced, and the possibility of abnormal friction or uneven wear of the load-bearing parts due to large lateral compression can be reduced; when vibration or upward movement tendency occurs, the walking component 6 can also be prevented from leaving the normal operating position. This reduces the possibility of the walking component 6 getting stuck, abnormally worn, or derailing while running along the conveying track 2, and provides a more stable mobile foundation for the suspension component 5 and the support component 4.

[0043] Within the linear conveying area, the traveling assembly 6 mainly bears the vertical load formed by the suspension assembly 5, the support assembly 4, and the aluminum material through the load-bearing wheels 601. It moves along the conveying track 2 with the traction side or connecting assembly 7. The two load-bearing positions bear the loads on both sides of the track, keeping the traveling assembly 6 below the conveying track 2 under normal load conditions. When operating normally and without significant lateral deviation, the two lateral guide wheels 602 roll in contact with the two sides of the web plate 202 to limit the lateral deviation of the traveling assembly 6 relative to the conveying track 2. The two lateral guide wheels 602 do not excessively clamp the web plate 202 to avoid increasing running resistance. When the traveling assembly 6 enters the curved conveying area, the direction of force transmitted by the connecting assembly 7 may form an angle with the track direction at the location of the traveling assembly 6, causing the traveling assembly 6 to tend to deviate to one side of the track. The lateral guide wheel 602 on the corresponding side bears the lateral force through rolling engagement with the corresponding side of the web 202 and restricts the traveling assembly 6 from continuing to move laterally; By using the lateral guide wheels 602 to bear the lateral force generated during the curve operation, the load-bearing wheels 601 can continue to mainly bear the vertical load, reducing the significant lateral sliding, edge squeezing, or unilateral wear of the load-bearing wheels 601 on the bearing surface; when the conveying route includes curved areas in different directions, the lateral guide wheels 602 set on both sides of the conveying track 2 respectively limit the offset in the corresponding direction, so that the walking component 6 can adapt to conveying paths with different left and right turns; When passing through track joints, during equipment start-up and shutdown, or when subjected to operational vibrations, the traveling component 6 may have a brief tendency to move upward. At this time, the anti-derailment wheel 603 restricts the traveling component 6 from continuing to move upward by rolling with the lower surface of the lower flange 203, thereby reducing the possibility of the load-bearing wheel 601 leaving the normal load-bearing position. During normal operation, the anti-detachment wheel 603 rolls along the lower surface of the lower flange 203 with the walking assembly 6, but does not bear the main vertical load formed by the suspension assembly 5, the support assembly 4 and the aluminum material; when the walking assembly 6 tends to move upward, the anti-detachment wheel 603 restricts the walking assembly 6 from continuing to move upward through the lower flange 203. Therefore, the walking component 6 is mainly supported by the load-bearing wheel 601 during normal transport, corrected by the lateral guide wheel 602 when there is a tendency to lateral deviation, and restricted by the anti-detachment wheel 603 when there is a tendency to swerve upward, so that it maintains a relatively stable operating state in both straight and curved areas.

[0044] Example 4 like Figure 4 As shown, based on Embodiment 3, the present invention provides a technical solution: Preferably, each connecting rod includes a first rod body 701 and a second rod body 702 coaxially and spaced apart. An adjusting frame 703 is fixedly connected to one end of the first rod body 701 near the second rod body 702. A through hole 705 is provided on one side wall of the adjusting frame 703 facing the second rod body 702. An adjusting screw 704 is fixedly connected to one end of the second rod body 702 near the first rod body 701. The adjusting screw 704 passes through the through hole 705 and extends into the adjusting frame 703. The through hole 705 and the adjusting screw 704 are in clearance fit. Two locking nuts 706 are threaded onto the adjusting screw 704. One locking nut 706 is located inside the adjusting frame 703, and the other locking nut 706 is located outside the adjusting frame 703. The two locking nuts 706 abut against the inner and outer surfaces of the side wall, respectively. The effective lengths of the two connecting rods are the same.

[0045] When the connection distance between the two suspension components 5 is fixed, it is difficult to adjust the spacing between the two support components 4 according to the length of the aluminum material, the support position, and the layout requirements of the conveying track 2. At the same time, if the lengths of the two connecting rods are inconsistent or the locking is not secure after adjustment, the geometric relationship of the parallelogram linkage mechanism is easily damaged, and the length changes under repeated traction, pushing, and running vibration.

[0046] In this embodiment, the effective length of the two connecting rods can be adjusted according to the length of the aluminum material and the support requirements, thereby changing the distance between the two suspension components 5 and the two support components 4 in the same group. This facilitates the adaptation of aluminum materials of different lengths or with different support positions, eliminating the need to configure connecting rods of different lengths for different support distances. After the connecting rods are adjusted, their effective length can be stably maintained, reducing the possibility of unexpected expansion and contraction of the connecting rods when repeatedly subjected to tension, pressure, and operational vibration, thus keeping the distance between the two suspension components 5 relatively stable. After the two connecting rods are adjusted to the same effective length, the parallel connection between them and the two suspension components 5 can be maintained, reducing pre-installation misalignment, rotational interference, or support direction deviation caused by inconsistent lengths of the two connecting rods.

[0047] When changing aluminum materials of different lengths or changing the distance between two support positions, first stop the conveying device and release the locking state on the two connecting rods so that each adjusting screw 704 can move along the axial direction of the connecting rod relative to the corresponding adjusting frame 703.

[0048] During adjustment, the first rod 701 and the second rod 702 of the two connecting rods are moved respectively to change the axial spacing between the two rods. The two connecting rods are adjusted by the same amount to ensure that their effective lengths are consistent. During the adjustment process, the adjustment amount of the two connecting rods can be confirmed by measuring the distance between the two suspension components 5, comparing the exposed dimensions of the two connecting rods, or using the length markings set on the connecting rods. When the distance between the two suspension components 5 reaches the predetermined support distance, firstly, the locking nut 706 located inside the adjustment frame 703 abuts against the adjustment frame 703, then the locking nut 706 located outside the adjustment frame 703 abuts against the adjustment frame 703 from the opposite direction, and then the two locking nuts 706 are tightened in opposite directions to keep the adjustment screw 704 in the adjusted position; After the two connecting rods are locked in sequence, their effective lengths are checked again. If there is a difference in the effective lengths of the two connecting rods, the locking state of one of the connecting rods is released and fine-tuned until the lengths of the two connecting rods are the same, and the two suspension components 5 do not show obvious relative deflection or pre-tightening deformation under no external force. After adjustment, the two connecting rods continue to transmit tension and pressure between the two suspension components 5 in the same group, and limit the spatial distance between the two suspension components 5 according to the adjusted effective length. Since the two connecting rods maintain the same length, they still maintain a parallel connection in the top view direction, so that the relative orientation of the two support components 4 does not change significantly due to the adjustment of the support distance; After the conveying device has been running for a period of time, the locking position can be checked. If the locking nut 706 becomes loose due to repeated loads or vibrations, it should be retightened to prevent changes in the effective length of the connecting rod. Adjustment and tightening operations should be performed when the connecting rod is not under significant tension or pressure to reduce the likelihood of the adjusting screw 704 being difficult to move under load or deviations in the locking position.

[0049] Example 5 like Figure 2 , Figure 3 and Figure 8 As shown, based on Embodiment 4, the present invention provides a technical solution: preferably, the supporting component 4 includes a vertical rod 401 and a plurality of support rods 402 spaced apart on the vertical rod 401 along the vertical direction, and the upper end of the vertical rod 401 is connected to the corresponding rotating part 502; Each support rod 402 extends outward from the vertical rod 401, and the end of the support rod 402 closer to the vertical rod 401 is lower than its free end away from the vertical rod 401, so that the support rod 402 gradually rises from the end closer to the vertical rod 401 to the free end.

[0050] When aluminum is conveyed along a curved path, during equipment start-up and shutdown, or subjected to operational vibrations, it may move along the support rod 402 toward its free end. When a horizontal support rod 402 is used, the aluminum does not tend to return on its own after deviating from the normal support position, and is likely to stay near the free end of the support rod 402, resulting in a reduced effective support range and increasing the risk of continued movement or detachment from the support rod 402.

[0051] In this embodiment, the area of ​​the support rod 402 near the vertical rod 401 forms a relatively low supporting position, so that the aluminum material can be kept in the supporting area near the vertical rod 401 during normal transportation. When the aluminum material is subjected to inertia, vibration or other external forces and moves along the support rod 402 towards the free end, its position rises accordingly. After the effect of causing the offset weakens or disappears, the aluminum material has a tendency to return to the low supporting area, thereby reducing the situation where the aluminum material stays near the free end of the support rod 402.

[0052] When loading aluminum materials, they are placed on corresponding support rods 402 in the two supporting components 4 of the same group, with the aluminum materials positioned in the lower support area near the vertical rod 401. During normal straight conveying, the aluminum materials are held in this area by their own gravity and supported by the two support rods 402 in the same layer. When the conveying device starts, stops, or passes through a curved conveying area, the aluminum materials may move relative to the support rods 402 due to inertia or running vibration. If the aluminum materials move along the support rods 402 towards the free end, they gradually reach a higher position under the action of the inclined setting, and further outward movement requires overcoming the corresponding gravitational force.

[0053] like Figure 2 and Figure 3 As shown, preferably, each of the support rods 402 is provided with an arc-shaped guide plate 403 on both sides along the aluminum material conveying direction, and the two arc-shaped guide plates 403 are provided along the extension direction of the support rod 402.

[0054] The tilting support rod 402 can cause the aluminum material moving towards the free end along the support rod 402 to tend to return to its original position. However, when the aluminum material passes through the curved conveying area, it may also shift back and forth along the conveying direction. The direction of this shift is different from the tilting direction of the support rod 402. It is difficult to rely solely on the tilting support rod 402 to convert it into a movement to return to the lower support area. This makes it easy for the aluminum material to remain in a shifted state after leaving the curve.

[0055] In this embodiment, the bidirectional offset of the aluminum material along the conveying direction can be guided accordingly. When the aluminum material offsets in either direction, the corresponding guide structure can restrict its continued free movement and convert the offset movement into controlled movement along the direction of the support rod 402. During the guiding process, the aluminum material moves towards the higher area of ​​the support rod 402. After the effect of offset weakens, it can return to the lower support area by utilizing the return trend formed by the inclined support rod 402, thereby reducing the situation where the aluminum material still retains obvious forward and backward offset after passing through the curved conveying area. The guide structures on both sides adapt to the offset of the aluminum material in different directions, which can take into account the curved conveying paths with different directions and the inertial effect of opposite directions when the conveying starts and stops, reducing the problem of the aluminum material approaching the free end of the support rod 402 or leaving the normal support area due to the gradual accumulation of offset.

[0056] The two arc-shaped guide plates 403 form a guide area for accommodating aluminum material between them; the two arc-shaped guide plates 403 respectively form arc-shaped guide edges on the side facing the guide area, the arc-shaped guide edges are higher than the top surface of the support rod 402, and the distance between the two arc-shaped guide edges gradually increases from the end closer to the vertical rod 401 to the end farther away from the vertical rod 401.

[0057] During normal transport, the aluminum material is located between two arc-shaped guide edges and the main weight is borne by the support rod 402. The two arc-shaped guide edges do not continuously clamp the aluminum material, allowing the aluminum material to move normally with the support assembly 4 and avoiding increased surface friction due to continuous contact. When the aluminum material passes through the curved conveying area and deviates relative to the support assembly 4 along the conveying direction, the side of the aluminum material facing the deviating direction first contacts the corresponding arc-shaped guide edge. As the deviating trend continues, the arc-shaped guide edge guides the moving direction of the aluminum material, so that while the aluminum material moves along the conveying direction, it gradually moves along the support rod 402 in a direction away from the vertical rod 401. As the aluminum material moves outward along the support rod 402, its position gradually rises with the tilt. As a result, the original offset along the conveying direction is converted into movement along the support rod 402, and the position rise creates the corresponding return condition, preventing the aluminum material from moving continuously along the conveying direction without being affected by the tilted support rod 402.

[0058] like Figure 8 As shown, preferably, a flexible pad 404 is provided at one end of the support rod 402 near the vertical rod 401. The flexible pad 404 is located in the low support area of ​​the support rod 402. A plurality of anti-slip ridges 405 are provided at intervals on the upper surface of the flexible pad 404. The anti-slip ridges 405 extend along the length direction of the aluminum material.

[0059] After the aluminum material returns to the low-position support area of ​​the support rod 402, it may still experience slight movement due to conveying vibration or start-stop inertia, and collide with the support rod 402. In this embodiment, the flexible pad 404 can buffer the contact impact when the aluminum material falls into the low-position support area, reducing the rigid collision between the aluminum material surface and the support rod 402. The anti-slip ridge 405 can increase the local friction in the low-position support area, reduce the slight movement of the aluminum material near the normal support position, and make its support position relatively stable after returning to its original position.

[0060] like Figure 2 and Figure 8 As shown, preferably, the free end of the support rod 402 is provided with an upwardly extending limiting part 406, the upper end of which is higher than the top surface of the support rod 402.

[0061] When the aluminum material experiences abnormal vibration, sudden stop, or is subjected to a large inertial force, it may continue to move towards the free end of the support rod 402, posing a risk of detaching from the support rod 402. In this embodiment, the limiting part 406 can form an end limit when the aluminum material moves to the free end of the support rod 402, reducing the problem of the aluminum material detaching from the support area.

[0062] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
