Device for fixing tail end of toilet roll

Abstract

A device for fixing the tail end of a toilet roll comprises grippers, a paper laying mechanism, a toilet roll jacking mechanism and a grinding mechanism. The toilet roll conveyed by the toilet roll conveying mechanism and paper laid by the paper laying mechanism are together jacked to the grippers through the paper jacking mechanism, and the two sides of the paper hanging down to the portions outside openings of the grippers are pressed together through the grinding mechanism. The device for fixing the tail end of the toilet roll has the beneficial effects that the defects brought by the tail end of the toilet roll bonded by glue are overcome, it is not necessary to apply pressure to the tail end of the toilet roll and the outermost layer of the toilet roll, the toilet roll can be prevented from being damaged, and the quality of the finished toilet roll can be improved; and moreover, if the device is used for fixing the tail ends of long toilet rolls without being cut, the situation that multiple sections of the short toilet rolls are wrapped after the long toilet rolls are cut into the multiple sections of short toilet rolls is avoided, the working procedures of toilet roll production are reduced, and the production efficiency is improved.

Description

technical field [0001] The present invention relates to an apparatus for producing toilet paper rolls, and more particularly to a device for securing the ends of toilet paper rolls. Background technique [0002] The production process of toilet paper rolls is to produce paper rolls with longer axial dimensions first, and then cut the long paper rolls into short paper rolls with shorter axial dimensions according to the size requirements of the finished paper rolls. Before cutting the paper roll, the tail end of the paper roll must be fixed on the paper roll to prevent the paper roll from loosening, and then the cutting operation can be carried out. [0003] In the prior art, a sealing machine is mostly used to apply glue to the tail end of the toilet paper roll, and the tail end of the toilet paper roll is bonded on the paper roll with glue. This kind of equipment that uses glue to fix the end of the paper roll has many problems such as the glue is easy to stain the machine...

AI Technical Summary

Problems solved by technology

Although this device overcomes the defect of using glue, its working principle is to press the tail end of the paper roll with the outermost layer of the paper roll itself, and it is difficult to precisely control the size of the pressing force

If the pressure is too high, it will easily damage the outer layer of the paper roll. If the pressure is too small, it will easily cause the tail end of the paper roll to not be fixed firmly, causing the paper roll to loosen unexpectedly in the subsequent slitting process, causing downtime accidents

Furthermore, no matter which of the above-mentioned techniques is used to fix the tail end of the paper roll, it is necessary to wrap each short paper roll after a tube of long paper roll is cut into multiple short paper rolls, and there are many production processes.
