Description

Embossing device of non-woven bag making machine Technical Field The utility model relates to the technical field of non-woven fabric production, in particular to an embossing device of a non-woven fabric bag making machine. Background Embossing of nonwoven fabrics is a key process of forming concave-convex textures on the surface of materials through mechanical or hot pressing processes, and the effect of the embossing is far more than decorative, but the embossing deeply influences the functionality, user experience and market competitiveness of products. Physical property enhancement of embossing of non-woven fabrics: 1. The product has the advantages of tear resistance, local stress dispersion structure formed by embossed points, reduced crack expansion (15-30% of tear strength improvement), 2 dimensional stability, texture locking fiber network, damp-heat environment shrinkage inhibition (water shrinkage rate reduction to < 3%), 3, air permeability/moisture permeability, and micro air flow channels (air permeability ≡20-50%) created by concave-convex structures. The use experience is as follows: 1. Micro-embossing with the touch sense of 0.1-0.3mm simulates the hand feeling of cotton cloth, 2. Visual sense, leather/wood grain imitation deep embossing (0.5-1.2 mm), 3. Functional, surface friction coefficient increasing (static friction coefficient > 0.35). In the embossing process of the non-woven fabric, proper embossing tension is required to be controlled aiming at different types of non-woven fabrics, the tension control is a core pulse of the non-woven fabric embossing process, and the linkage quality defect can be caused by too large or too small. Too much tension (above the material yield limit) can lead to uncontrolled embossing depth, texture deformation and breakage, and too little tension (below the critical overhang tension) can lead to embossing blurring and ghosting, interlayer composite defects, and risk of mechanical damage. In the prior art, in the operation line for carrying out non-woven fabric embossing operation by adopting the embossing roller, the tension of the non-woven fabric in the embossing operation line is influenced by the pressure influence of the embossing roller and the increase of the angular speed of the winding roller along with the increase of the thickness of the rolled non-woven fabric, in order to ensure the speed uniformity of the non-woven fabric in the transmission process as much as possible, a torque motor or an asynchronous motor with a frequency converter is generally selected to change the rotating speed of the winding roller to adjust the final linear speed of the winding roller, and because the winding roller and the embossing roller have longer distance, the tension uniformity transmission is not timely, and is influenced by the friction force of a plurality of guide rollers in the winding roller and the embossing roller, the tension uniformity is not completely uniform, and the tension is changed due to the change of the ductility of the non-woven fabric after the embossing roller, so that the tension of the non-woven fabric before and after the embossing roller floats in the actual embossing process of the non-woven fabric, the situation such as out of control of embossing depth, texture deformation and fracture, fuzzy embossing and double images, interlayer compound defects, mechanical damage and the like occur.
