A non-woven fabric coating production method and its flattening device

Abstract

A nonwoven fabric laminating planishing device comprises a rack and is characterized in that one pair of planishing rollers vertically overlapped are arranged on the rack, one pair of hydraulic oil cylinders are respectively arranged at the upper part and the lower part of the rack, the bottom ends of piston rods of the upper pair of hydraulic oil cylinders are connected with the end part of the upper planishing roller, the bottom ends of piston rods of the lower pair of hydraulic oil cylinders are connected with the end part of the lower planishing roller, the upper planishing roller and the lower planishing roller are respectively driven by motors to oppositely rotate, and ceramic heating bodies are mounted in the planishing rollers. The nonwoven fabric laminating planishing device has the characteristics of being even in planishing, low in production cost, high in automation degree, great in product quality, convenient to mount, and the like. A thickness gauge carries out thickness detection on the nonwoven fabric. If the nonwoven fabric is too thick, the ceramic heating bodies of the planishing rollers produce heat and heat the nonwoven fabric, so that the nonwoven fabric is even in surface thickness and free of defective points. Through adopting the planishing technology, defects, such as melting points and filament breakage can be well overcome in the production process of the nonwoven fabric.

Description

technical field [0001] The invention belongs to the technical field of new materials, and in particular relates to a method for producing a non-woven fabric coating and a flattening device thereof. Background technique [0002] Currently, as attached Figure 5 , in the process of processing the raw materials of coated non-woven fabrics, in order to reduce the cost of gluing uniformity and reduce the amount of gluing, the distance between the gluing die head and the back roller will be minimized, while the actual production of non-woven fabrics A common problem in the production process is that a large number of defects such as melting points and broken wires will be produced during the manufacturing process, forming high points one by one. The thickness of the high points is far beyond the normal area. At this time, because the gap between the gluing die head and the gluing back roller is fixed, the high point will tear the coating film because it cannot pass through, forcin...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a flattening device for a non-woven fabric coating with uniform thickness and no flaws and thick spots, so as to solve the technical problems of the existing non-woven fabric coating film with large differences in single-point thickness, which is not conducive to subsequent processing, etc.
