Paper winding machine protection device capable of effectively preventing stall

Abstract

The invention relates to the technical field of paper winding machines, in particular to a paper winding machine protection device capable of effectively preventing stall. The device comprises a mounting frame, an annular groove is formed in the inner wall of the mounting frame, three evenly-distributed speed reduction blocks are movably connected to the inner wall of the annular groove, damping holes are formed in the inner walls of the speed reduction blocks, iron blocks are fixedly connected to the inner walls of the speed reduction blocks, a rotating shaft is movably connected to the middle of the mounting frame, evenly-distributed sliding grooves are formed in the middle of the rotating shaft, and springs are fixedly connected to the inner walls of the sliding grooves. According to the paper winding machine protection device capable of effectively preventing stall, through cooperative use of the speed reduction blocks and the damping holes, when a paper winding machine rotates rapidly, the speed reduction blocks can be relatively fixed to the rotating shaft under the action of magnetic attraction force of electromagnets and the iron blocks, the viscosity of magnetorheologicalfluid in the annular groove is increased at the moment, the magnetorheological fluid can hardly pass through the speed reduction blocks and the damping holes, and therefore the stall prevention effectis achieved, the winding quality of the paper winding machine is effectively prevented from being reduced, and the practicability is improved.

Description

Technical field[0001]The invention relates to the technical field of paper reeling machines, in particular to a paper reeling machine protection device that effectively prevents stalls.Background technique[0002]The reel is the first complete set of equipment after the paper machine. Relying on the weight of the paper roll and the friction of the rotation of the cold cylinder, the paper is driven to be evenly wound. Therefore, the paper roll makes the paper more uniform and can meet the needs of different papers. The current paper rolls often Some problems have occurred, resulting in unsatisfactory roll paper effects.[0003]With the gradual increase in quality of the current paper reel during use, the rotational inertia of the reel shaft will gradually increase, resulting in frequent stalls.

AI Technical Summary

Problems solved by technology

Relying on the weight of the reel roll and the friction of the cold cylinder rotation to drive the paper to be evenly wound, so the reel makes the paper more uniform and can meet the needs of different papers. The current reel is often used during use. Some problems occurred, resulting in unsatisfactory roll paper effect

[0003] As the quality of the current paper reel gradually increases during use, the rotational inertia of the reel's shaft will gradually increase, resulting in frequent stalls, and the reel will cause problems such as wrinkles in the paper reel , resulting in problems with the quality of the roll paper. At this time, it is necessary to interrupt the production and adjust the roll machine, which is time-consuming and labor-intensive, and seriously delays the production schedule.
