Technical Field

[0001] The utility model relates to the technical field of rollers, in particular to an early warning anti-collision roller. Background Art

[0002] Conveyors can be categorized by their operating method as follows: belt conveyors, integrated loading and unloading conveyors, screw conveyors, bucket elevators, roller conveyors, plate chain conveyors, mesh belt conveyors, and chain conveyors. Regardless of the type of conveyor, rollers are required to coordinate with each other to transmit or transfer power. However, existing rollers, especially those equipped with K-series bearings and corresponding adapter sleeves, are prone to misalignment during use.

[0003] The main reason is that when the roller rotates at high speed, it expands and contracts due to heat and cold, and the metal fatigue will cause relative displacement between the adapter sleeve and the shaft. Over time, the locking nut will loosen, resulting in axial movement of the roller, which can easily cause production safety accidents such as belt deviation, belt slippage, belt tearing, and belt friction fire.

[0023] Embodiment: A warning anti-channeling roller, such as Figures 1-4 As shown, it includes a roller 1 and a bearing seat 2, a bearing 3 is installed between the roller 1 and the bearing seat 2, and the roller 1 can rotate between the two sets of bearing seats 2 through the bearing 3. The inner and outer walls of the bearing 3 are provided with anti-stringing components, and the anti-stringing components include a tightening sleeve 4 and a tightening nut 5. The tightening sleeve 4 is inserted between the roller 1 and the bearing 3 and the tightening sleeve 4 has an interference fit with the roller 1 and the inner ring of the bearing 3. One side of the tightening sleeve 4 is provided with an external thread and is threadedly connected with a tightening nut 5. A radial tightening groove 7 is radially provided on the side wall of the tightening sleeve 4, and a tightening nut 8 is threadedly connected to the radial tightening groove 7. A screw groove is provided on the roller 1 at the position corresponding to the tightening nut 8. When the tightening sleeve 4 is inserted, the tightening nut 8 is tightened to fix the tightening sleeve 4 to the roller 1 to prevent the tightening sleeve 4 from axial movement, thereby avoiding axial sliding of the roller 1 and causing harm.

[0024] Furthermore, the outer wall surface of the adapter sleeve 4 is also sleeved with a shaft retaining ring 6, which is located between the bearing 3 and the fastening nut 5. The shaft retaining ring 6 is annular and the outer wall surface of the shaft retaining ring 6 is provided with evenly spaced inclined metal sheets. The outer wall surface of the adapter sleeve 4 and the inner ring wall surface of the bearing 3 are conical inclined surfaces. When the fastening nut 5 is tightened, the fastening nut 5 and the metal sheet are tightly pressed to allow the shaft retaining ring 6 to squeeze the bearing 3, further causing the bearing 3 to squeeze the adapter sleeve 4 and then have an interference fit with the roller 1. The evenly spaced inclined metal sheets also reduce the possibility of rusting caused by direct contact between the fastening nut 5 and the bearing 3 in harsh environments, making disassembly more convenient.

[0025] Furthermore, a dustproof groove 9 is provided at the position of the tightening sleeve 4 corresponding to the radial fastening groove 7, and a support cap 10 is installed in the dustproof groove 9 with interference fit.

The avoidance groove 11 cooperates with the tightening nut 8 to reduce the thread slippage caused by extrusion when the fastening nut 5 is tightened on the tightening sleeve 4.

[0026] In other embodiments, the anti-cross-contamination component also includes a detector 13. A detection slot 12 is provided on the bearing seat 2. The detector 13 is fixedly installed in the detection slot 12. In this embodiment, the detector 13 is a wireless transmission sensor. Once the bearing seat 2 is displaced and touches the detector 13, it will emit electromagnetic induction to a nearby collection receiver and transmission alarm system, which will cause the on-site sound and light alarm to sound an alarm, informing the current administrator to deal with it in time. It can also be transmitted to the administrator's mobile phone or the remote central control platform through the software system using wireless or wired signals for mobile and remote early warning management.

[0027] In other embodiments, the anti-cross-talk component includes a detector 13, a detection slot 12 is opened on the bearing seat 2, the detection slot 12 is an inclined slot with its opening facing the bearing 3, the detector 13 is fixedly installed in the detection slot 12 and its output end faces the bearing 3, the detector 13 is a distance sensor, when the bearing 3 is displaced in the bearing seat 2, the detector 13 can immediately detect the change in the data, thereby supporting the subsequent alarm function.

[0028] In a preferred embodiment, both ends of the adapter sleeve 4 are sleeved with shaft retaining rings 6, thereby fastening the bearing 3 from both sides.

[0029] The working principle of the present invention is as follows: an adapter sleeve 4 is inserted between the drum 1 and the bearing 3, and the adapter sleeve 4 is fastened to the drum 1 by passing the adapter sleeve 4 through a radially arranged adapter nut 8. The bearing 3 and the adapter sleeve 4 are interference fit with each other by tightening the fastening nut 5, and then the adapter sleeve 4 is squeezed to make the adapter sleeve 4 interference fit with the drum 1. Under the double fixation, the drum 1 and the inner ring of the bearing 3 are fastened together through the adapter sleeve 4. The displacement alarm function of the bearing 3 is also supported by a detector 13 that can detect whether there is displacement between the outer ring of the bearing 3 and the bearing seat 2, thereby increasing the anti-cross-contact function of the drum 1 from both the inner and outer parts of the bearing 3 and improving the safe production capacity.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
