Description

Technical Field

[0001] The utility model relates to the technical field of friction roller assemblies, in particular to a friction accumulation roller assembly. Background Art

[0002] At present, assembly lines mostly use low-speed conveying, and workers assemble along the way. This method increases the labor intensity of workers and also affects their assembly efficiency. In addition, the assembly line also has fixed-point assembly, so the conveyor line must be frequently started and stopped, which increases energy consumption and wear of transmission parts. For this reason, the assembly line began to use friction accumulation roller assemblies for control. During assembly, the workpiece is placed on the pallet, and the pallet is conveyed in a controllable rhythm. It can have enough power to ensure the pallet moves forward, and it can avoid slipping when the pallet stops, so that the line drive motor can maintain normal and continuous operation.

[0003] The existing friction accumulation roller assembly uses friction to stop the roller from rotating. In some cases, in order to increase the friction force, the clamping spring force must be increased, which leads to increased wear of the friction plate and shortened service life. It is more troublesome to replace the friction plate, and the assembly line needs to be stopped, causing unnecessary losses. Utility Model Content

DETAILED DESCRIPTION

[0015] In order to deepen the understanding and recognition of the utility model, the technical solutions in the embodiments of the utility model will be clearly and completely described and introduced in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments, and are not intended to limit the embodiments in any form. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

When in use, the roller 3 drives the tray to move. When the roller 3 needs to stop, the connecting spring 8 squeezes the fixed sleeve 13, thereby pushing the fixed sleeve 13 to move. The friction member 7 at the side end of the fixed sleeve 13 abuts against the mounting sleeve 10, and drives the roller 3 to stop rotating through friction.

[0017] The friction member 7 is an arc-shaped structure, and five friction members 7 can form a circular ring structure. The outer wall of the friction member 7 is a stepped structure, and a positioning protrusion 12 is fixedly connected to the inner wall of the friction member 7. Both sides of the friction member 7 are inclined structures. The outer wall of the fixing sleeve 13 is a stepped structure, and a positioning groove 14 is provided on the outer wall of the fixing sleeve 13. When the friction member 7 and the fixing sleeve 13 are installed, the positioning protrusion 12 is inserted into the positioning groove 14 to position and connect the friction member 7, and then the fixing sleeve 13 and the friction member 7 are connected by buckles or bolts. When a certain friction strip 11 is severely worn, the friction member 7 can be replaced.

[0018] A friction strip 11 is fixedly connected to the side end of the friction member 7. The friction strip 11 is an arc-shaped structure. The friction strip 11 extends from the outer wall of the friction member 7 to the inner wall. A plurality of plug-in slots 15 are provided on the left side of the mounting sleeve 10. A friction block 16 is plugged into the plug-in slot 15. The friction block 16 is fixedly connected to the inner wall of the plug-in slot 15 by bolts. The side end of the friction strip 11 abuts against the friction block 16. When the friction member 7 rotates with the rotating shaft 1, the contact area between the friction strip 11 and the friction block 16 is continuously changing, so that the friction strip 11 is prevented from being in contact with the friction block 16 for a long time at a certain point. Long-term contact can generate a large amount of heat. At the same time, the loss of the friction block 16 and the friction strip 11 can be reduced, and the service life of the friction strip 11 and the friction block 16 can be greatly increased.
