Description

Technical Field

[0001] The utility model relates to the technical field of mechanical self-aligning roller groups, in particular to an upper self-aligning roller group for conveniently replacing rollers. Background Art

[0002] Mechanical self-aligning roller groups often use retaining rollers, friction rollers or tapered rollers to adjust belt deviation. The main structure of the self-aligning roller group is divided into two main components. One component is the belt deviation detection mechanism, which is the power source for the deflection of the mechanical self-aligning roller group. The other component is the rotating support mechanism of the roller frame, which is used to carry the rotation of the roller frame.

[0003] Existing self-aligning roller assemblies mostly use a retaining roller type, such as those in patents CN208647841U and CN203638634U. After the tape deviates, the side of the tape pushes the retaining roller to deflect the roller frame, thereby gradually restoring the tape. However, the existing tape structure is a sandwich structure. Long-term contact and stress between the sides of the tape and the retaining roller can easily cause the sides of the tape to delaminate and debond, damaging the tape. Similarly, a solution similar to utility model patent CN203497649U, which uses a friction roller to drive the deflection of the roller frame due to the deviating tape, still has the disadvantage of damaging the tape, but the damage to the tape is less than that of a retaining roller structure. Similar to the utility model patent CN204823075U, a tapered roller is used as a side roller. The belt is deflected and the friction difference between the left and right sides caused by the linear velocity difference after the belt deviates is used to adjust the deflection of the correction device. This solution achieves a correction effect and avoids damage to the belt. However, considering that the friction generated by the linear velocity difference is used alone to adjust the deflection of the roller frame, the deflection force of the roller frame is small, and the correction effect of the belt deviation is general. At the same time, because the force conditions of the rollers in the correction roller group are more complex than those of the rollers in ordinary trough rollers and transition rollers, the rollers of the self-aligning roller group are subjected to axial forces during the deflection process, making the self-aligning rollers more susceptible to damage. Therefore, during normal use of the conveying equipment, the life of the rollers of the self-aligning roller group is generally shorter than that of ordinary roller groups, and the rollers need to be replaced more frequently. The existing roller replacement solution is to manually lift the belt to replace the rollers, which is time-consuming, labor-intensive, and has safety risks. To address this problem, we propose an upper self-aligning roller group for convenient roller replacement. Utility Model Content
