Description

Technical Field

[0001] This invention relates to the field of cargo conveying technology, and in particular to a belt alignment mechanism and a belt conveyor. Background Technology

[0002] Belt conveyors are equipment used in the tobacco industry to continuously transport tobacco materials on production lines. They are widely used in tobacco processing production lines, leaf re-drying lines, and other tobacco material conveying processes. They serve as auxiliary connecting equipment between various main equipment and can continuously transport various materials such as tobacco packs, tobacco leaves, tobacco shreds, tobacco stems, and tobacco shreds.

[0003] Belt conveyors transport materials via belts. In actual production, belt misalignment often occurs due to factors such as design, installation quality, environment, belt tension, and material conveying conditions. On the one hand, this directly leads to uneven stress on the left and right sides of the belt, thus shortening the belt's service life; on the other hand, it can cause material leakage. Moreover, when the belt misalignment is severe, it can cause the belt to wear out rubber powder, fibrous strands, or even tear and crack, affecting product quality.

[0004] In related technologies, adjusting belt misalignment on conveyors relies entirely on the experience of maintenance personnel. This method has three shortcomings: First, it is delayed, as maintenance personnel typically only make adjustments when the belt deviates from its designated position. Second, it is limited, as belt misalignment can only be addressed when it is discovered by maintenance or operator personnel. Misalignment that is not detected or is discovered too late cannot be adjusted in a timely manner, which can lead to serious consequences. Third, it is uncontrollable, as adjusting belt misalignment is highly dependent on the maintenance personnel's skill level and job competence. Improper adjustment methods can accelerate belt misalignment, resulting in irreversible consequences.

[0005] It should be noted that the information disclosed in the background section of this invention is intended only to enhance the understanding of the overall background of this invention, and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] This invention provides a belt alignment mechanism and a belt conveyor, which can maintain the stable position of the belt during the operation of the belt conveyor.

[0007] According to one aspect of the present invention, a belt alignment mechanism is provided, comprising:

[0008] Mounting rack; and

[0009] The transmission mechanism includes a drive roller for driving a belt. The drive roller includes a first roller and a second roller. A first end of the first roller and a first end of the second roller are respectively connected to a mounting frame.

[0010] In some embodiments, the transmission mechanism further includes an adjustment component connected between the first roller and the second roller, wherein the first roller and / or the second roller are configured to oscillate relative to the adjustment component.

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] In the description of this invention, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "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 invention 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 limiting the scope of protection of this invention.

[0036] refer to Figure 1 As shown, in some embodiments of the belt alignment mechanism provided by the present invention, the belt alignment mechanism includes a mounting frame 10 and a transmission mechanism. The transmission mechanism includes a drive roller for driving the belt. The drive roller includes a first roller 20 and a second roller 30. The first end of the first roller 20 and the first end of the second roller 30 are respectively connected to the mounting frame 10. The second end of the first roller 20 and the second end of the second roller 30 are flexibly connected so that the axes of the first roller 20 and the second roller 30 can swing relative to each other.

[0037] By setting the drive roller to include a first roller 20 and a second roller 30, i.e., divided into two roller sections, and flexibly connecting the first roller 20 and the second roller 30 so that their axes can swing relative to each other, the axes of the first roller 20 and the second roller 30 can swing relative to each other within a certain angle range when the belt deviates from its preset running direction, thereby achieving adjustment of the belt position and maintaining the normal operation of the belt.

[0038] In other embodiments, the belt alignment mechanism also includes sensors and a control system. The sensors monitor the position and offset of the belt, and the control system further realizes automatic control and adjustment of the belt position, which can improve the efficiency and accuracy of alignment.

[0039] refer to Figure 2As shown, in some embodiments, the transmission mechanism further includes an adjustment assembly 40 connected between the first roller 20 and the second roller 30, the first roller 20 and / or the second roller 30 being configured to oscillate relative to the adjustment assembly 40.

[0040] When the belt deviates, the relative position and angle between the first roller 20 and the second roller 30 can be adjusted and changed by the swing of the first roller 20 and / or the second roller 30 relative to the adjusting component 40, thereby pushing the belt to move and return to the preset working position, thus achieving the effect of real-time adjustment and correction of belt deviation, maintaining the belt in normal working condition, and ensuring the stability of belt drive.

[0041] In some embodiments, the adjusting assembly 40 includes a coupling 41.

[0042] The coupling 41 can transmit rotational torque and torque, while allowing relative movement between shafts. When the belt deviates, the pressure exerted by the belt on the first roller 20 and the second roller 30 changes in real time. Therefore, the pressure exerted by the first roller 20 and the second roller 30 on the coupling 41 is also different. Thus, the coupling 41 applies different reaction forces to the first roller 20 and the second roller 30, causing the first roller 20 and the second roller 30 to swing relative to each other. This changes the friction between the belt and the first roller 20 and the second roller 30. This friction can resist further belt deviation, and the swing of the first roller 20 and the second roller 30 can also gradually push the belt to move and return to the preset working position, achieving the effect of real-time adjustment and correction of belt deviation.

[0043] In some embodiments, reference Figure 3 As shown, coupling 41 includes a curved gear coupling.

[0044] Curved gear couplings have high torque transmission efficiency, can absorb vibration and shock, and have strong correction capabilities in the axial, radial and angular directions.

[0045] The specific form of coupling 41 can be selected in various ways, such as flexible coupling or universal joint coupling.

[0046] In other embodiments, coupling 41 can be replaced with other structures that enable flexible connections.

[0047] refer to Figure 2 As shown, in some embodiments, the adjusting assembly 40 includes two couplings 41, which are respectively connected to the second end of the first roller 20 and the second end of the second roller 30. The adjusting assembly 40 also includes a connecting device for connecting the two couplings 41.

[0048] By setting two couplings 41, both the first roller 20 and the second roller 30 can swing relative to the adjusting component 40, improving the flexibility of the relative swing of the first roller 20 and the second roller 30 and increasing the belt's correction efficiency. Furthermore, by using a connecting device to connect the two couplings 41, force and torque can be transmitted between them, allowing for real-time correction of belt running deviations based on changes in the force on the first roller 20 and the second roller 30, thus restoring the belt to normal operation.

[0049] refer to Figure 5a , Figure 5b and Figure 5c As shown, in some embodiments, the second end of the first roller 20 and / or the second roller 30 is provided with a recess, and the coupling 41 is embedded in the recess.

[0050] By setting the recessed portion, the connection stability between the coupling 41 and the first roller 20 and / or the second roller 30 can be improved, ensuring the working reliability and stability of the adjustment assembly 40.

[0051] refer to Figure 2 , Figure 5a , Figure 5b and Figure 5c As shown, the first end of the first roller 20 and / or the second roller 30 is provided with a protrusion, which is used to connect with the mounting frame 10 and can be used to install a motor reducer or bearing.

[0052] In some embodiments, the first roller 20 and the second roller 30 have the same structure, as shown in the reference. Figure 4 As shown.

[0053] refer to Figure 7 As shown, in some embodiments, the connecting device includes a connecting shaft 42 and a bearing 43. The two ends of the connecting shaft 42 are respectively connected to two couplings 41. The bearing 43 is sleeved on the connecting shaft 42, and the axis of the bearing 43 is fixed relative to the mounting bracket 10.

[0054] The above settings fix the position of the connecting device relative to the mounting frame 10, thereby ensuring the installation stability of other components in the adjustment assembly 40, and thus ensuring the working stability and reliability of the first roller 20 and the second roller 30.

[0055] In related technologies, drive rollers are usually integral structures, while the drive roller of the present invention includes a separate first roller 20 and a second roller 30.

The connecting device also includes a bearing cover 44 that fixes the bearing 43 relative to the ear plate 60.

[0060] For details, please refer to the following: Figure 2 and Figure 7 As shown, in the above embodiment, the connecting device includes two bearings 43, the connecting portion 62 of the ear plate 60 is located between the two bearings 43, and the bearing cover 44 fixes the bearings 43 relative to the connecting portion 62. Through this arrangement, the connecting rod 50 and the ear plate 60 support the drive roller, ensuring the working stability of the first roller 20 and the second roller 30.

[0061] The following describes a specific embodiment of the belt alignment mechanism of the present invention:

[0062] refer to Figure 1 and Figure 2 As shown, the belt alignment mechanism provided by the present invention includes a mounting frame 10, a transmission mechanism, and a support structure. The transmission mechanism includes a drive roller for driving the belt and an adjustment component 40.

The bearing 43 is sleeved on the connecting shaft 42. The connecting part 62 is located between the two bearings 43. The connecting part 62 has a through hole, and the connecting shaft 42 passes through the through hole. (Reference) Figure 7 As shown, the bearing 43, bearing cover 44, and retaining ring 45 cooperate with the connecting part 62 of the ear plate 60 to achieve the fixation and sealing of the bearing 43.

The belt is reset by the swing of the first roller and the second roller when the belt runs off track, thereby realizing real-time correction of the belt. This can improve the stability of belt operation, effectively avoid belt running off track quality accidents caused by inadequate inspection or lack of maintenance skills, and ensure the safety and reliability of the production line.
