Tension-free compounding and slitting machine for elastic fabric

Abstract

The invention relates to a tension-free compounding and slitting machine for elastic fabric, and belongs to the technical field of cloth cutting equipment. The whole tension-free compounding and slitting machine is automatically controlled by a human-computer interface of a PLC (Programmable Logic Controller). The tension-free compounding and slitting machine for the elastic fabric comprises a first unreeling mechanism, a second unreeling mechanism, a compounding mechanism and a slitting and reeling mechanism, wherein the first unreeling mechanism and the second unreeling mechanism are both connected with the compounding mechanism; the compounding mechanism is connected with the slitting and reeling mechanism; the first unreeling mechanism is a tension-free unreeling mechanism which consists of a first drive separator roll, a floating unreeling roll, a tension detection control device, a first linkage separator roll and a plurality of twitch rollers; the compounding mechanism is provided with a third driving separator roll, a water-cooling press roll and a glue spray device; the water-cooling press roll is close to the glue spray device and is used for compounding the elastic fabric; the slitting and reeling mechanism is provided with a stripping and cutting device, a first reeling shaft, a second reeling shaft and a magnetic powder clutch which brakes the reeling shafts. The whole tension-free compounding and slitting machine is practical and reliable in structure design, low in cost and good in economic benefit, and is capable of realizing the tension-free reeling and unreeling, compounding, and slitting production of the elastic fabric.

Description

technical field [0001] The invention relates to the technical field of cloth cutting equipment, in particular to a glue compounding and stripping equipment for high elastic cloth. Background technique [0002] Hygienic diapers are widely used in the daily life of babies. Baby diapers are mainly composed of surface covering layer, absorbent core layer and base fabric. The surface covering layer is attached with elastic waist and Velcro to ensure the use It can be close to the baby's body to prevent the diaper from falling off; because the elastic fabric has high elasticity and good stretchability, more and more high-elastic non-woven fabrics are used as the base fabric of the existing baby diapers (hereinafter Elastic cloth for short); In addition, existing diapers are also bonded with a bottom PE breathable film on the outer side of the non-woven base fabric. Therefore, on the production line for the production of diapers, it is necessary to have a compound machine for glui...

AI Technical Summary

Problems solved by technology

However, the existing cloth slitting machine is suitable for slitting ordinary inelastic cloth because it unwinds under tension, and because elastic cloth has the characteristics of large elasticity, large stretching deformation, and easy curling, etc., Tension unwinding is not suitable for slitting and unwinding, so when the existing slitting machine is used for slitting elastic cloth, there are large cutting width errors, serious unwinding and winding wrinkles, and serious deformation of the fabric after slitting And other problems, so the existing slitting machine is not suitable for the slitting operation of elastic cloth

In addition, the existing slitting machine does not have the function of gluing and laminating. When using compound auxiliary materials (such as adhesives, Velcro, etc.), it needs to be used in conjunction with a special fabric laminating machine, which is not only cumbersome to operate and high in production costs. And there will be incoordination between the slitting machine and the supporting compound machine, which will affect the production efficiency and product yield
