Embodiment Construction

[0024] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] combine figure 1 , 2 As shown, the flattening device of the non-woven fabric coating is composed of a frame 1, a hydraulic cylinder 2, upper and lower flattening rollers 3, 31 and a piston rod 4, etc., and a pair of hydraulic cylinders are respectively provided on the upper and lower parts of the frame 1 2. The end of the piston rod 4 of the upper pair of hydraulic cylinders 2 is connected to the end of the upper flattening roller 3, the end of the piston rod 4 of the lower pair of hydraulic cylinders 2 is connected to the end of the lower flattening roller 31, and the hydraulic cylinder 2 passes through Adjust the height of the piston rod 4, and then adjust the gap between the flattening rollers 3 to affect the pressure of the flattening rollers 3 on the non-woven fabric. The upper and lower flatt...

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...
