Abstract

The invention relates to the technical field of lining paper processing equipment, in particular to a winding device for producing lining paper, which comprises a side connecting frame, wherein a winding roller is rotationally connected to the inner end surface of one side of the side connecting frame, a shaft lever is fixedly connected to one side of the middle part of the winding roller, an arc-shaped pressure relief shaft sleeve is sleeved on the inner cambered surface of the winding roller, an air cavity is formed in the inner cambered surface of the arc-shaped pressure relief shaft sleeve, and a shaft shifting block is slidingly connected to the upper end of the outer cambered surface of the shaft lever. The top of the arc-shaped spring frame is sunk and the bottom of the arc-shaped spring frame is expanded outwards to be adaptive to deformation by utilizing the pressure transmission of the air cavity through the cooperative stress absorbing structure of the arc-shaped pressure relief shaft sleeve and the arc-shaped spring frame. The structure can actively absorb the outer extrusion stress born by the inner coiled material, synchronously supports the arc-shaped pressure relief plate in a reverse direction through the arc-shaped spring frame, distributes the stress to the elastic roller surface, effectively relieves the creep deformation of the inner coiled material, avoids the problem of inconsistent tightness between the inner and outer coiled materials, and reduces the quality defect of edge-burst warping in the subsequent slitting process.

Description

Coiling mechanism is used in lining paper production Technical Field The invention relates to the technical field of lining paper processing equipment, in particular to a winding device for producing lining paper. Background The lining paper (such as aluminum foil lining paper for cigarettes) is soft in texture and easy to fold, multiple technical pain points exist in the production and winding process, firstly dust sundries are easy to adhere to the surface, the coiled material is easy to bulge and damage after winding, the subsequent use is affected, secondly the traditional leveling mechanism is designed in a one-way or fixed-interval mode, the leveling requirements of lining paper with different thicknesses cannot be adapted, the leveling pressure cannot be dynamically adjusted along with the winding progress, the deviation phenomenon is easy to occur in the winding process, the response of the existing deviation correcting device is lagged, the deviated coiled material section is difficult to quickly correct, and fourthly when the winding diameter of a winding roller is increased, the tension applied to the lining paper is easy to abnormally fluctuate, the stretching deformation or the loosening folding is caused, and the mechanisms lack of cooperative linkage control. The lining paper is a key material in the fields of tobacco, food packaging and the like, the tail end rolling link of the production flow is a core procedure for determining the quality, the production efficiency and the equipment suitability of a finished product, the traditional and the existing rolling device can finish the basic rolling function, but is limited by material characteristics, structural design and control logic, and the technical bottlenecks in aspects of tension control, rolling shape regularity, surface protection, suitability, automation degree and the like generally exist, so that the lining paper becomes a main constraint factor for industry upgrading. One patent publication No. CN119858837A discloses a lining paper winding device applied to a wire laying machine, which comprises a driving assembly, a guiding assembly, a bearing assembly and a locking assembly, wherein the driving assembly comprises a driving piece and a rotating shaft, one end of lining paper is attached to the surface of a lining paper winding drum, the locking assembly is arranged at the end part of the rotating shaft to clamp the lining paper winding drum, then the driving piece is controlled to drive the lining paper winding drum to rotate so as to wind the lining paper, after winding, the locking assembly is dismounted from the rotating shaft, the lining paper winding drum is pulled out from the rotating shaft, and as the surface of the lining paper winding drum is provided with an empty groove extending along the axial direction, the lining paper winding drum can be compressed in a manner of extruding the lining paper wound outside the lining paper winding drum, so that the outer wall of the lining paper winding drum extrudes the empty groove, the outer diameter of the lining paper winding drum is reduced under extrusion, and the lining paper winding drum is taken out from the lining paper of the winding drum, the dismounting is very simple and labor-saving, the efficiency of lining paper recovering is improved, and the lining paper damage can be avoided. According to the device, the empty groove extending along the axial direction is formed in the surface of the lining paper roll, the lining paper roll is extruded to enable the outer diameter of the lining paper roll to be contracted after winding is completed, so that the lining paper roll is rapidly disassembled, the lining paper recovery efficiency is improved, damage to lining paper in the disassembling process can be avoided, but in the technical scheme, tension maintenance of surface layer paper in the winding process is only concerned, stress accumulation effect inside a coiled material is ignored, under the action of winding pressure, the inner coiled material is continuously extruded by the outer coiled material, creep deformation can be generated when the inner coiled material is in a high-pressure state for a long time, the inner and outer tightness of a finished coiled material is inconsistent, the inner and outer stress difference can be intensively released in the follow-up slitting process, the quality problems such as edge burst or warping of the coiled material are caused, and the qualification rate of the finished product is reduced.
