High-performance sound-absorption and thermal-insulation material production line

Abstract

The invention relates to a high-performance sound-absorption and thermal-insulation material production line which comprises a main frame, wherein a plastic extruding machine is arranged above the main frame; a round roller net forming machine is arranged in the main frame; a melt-blow spinning box, a dosing pump and a filter are connected together and arranged above the round roller net forming machine; the melt-blow spinning box is connected with a plastic extruding machine; a wind heater is arranged on a side part of the round roller net forming machine; an induced draft fan and a blower are arranged on a side part of the wind heater; the wind heater is communicated with the centrifugal induced draft fan and the blower through pipelines; a dot hot-rolling roller and a dividing and cutting machine are arranged on a side part of the main frame; a spinneret and a spinning micropore are arranged below the melt-blow spinning box; and the micropore diameter ranges from 0.3 mm to 0.4 mm. In the invention, through the technical improvement on key process equipment, such as melt-blow, filling, sewing and the like, the high-performance sound-absorption and thermal-insulation material production line is built, and the procedures of product melt-blow, filling and sewing are accomplished in the same production line.

Description

technical field [0001] The invention relates to a production line, in particular to a high-performance sound-absorbing and heat-insulating material production line. Background technique [0002] The existing YDB sound-absorbing and heat-insulating materials are mostly composed of polyester fibers and polypropylene superfine fibers, and the surface is covered with spunbonded cloth or aluminum foil. During manufacture, polyester fibers and polypropylene superfine fiber products are generally blown, and then the surface is covered with spinning. Adhesive cloth or aluminum foil treatment. The process is manufactured separately in multiple production lines or multiple manufacturers. The finished fiber cotton product has been circulated many times. Due to the influence of environment, storage, humidity, etc., its fluffy structure and insulation performance are destroyed, which affects the quality of sound absorption and heat insulation. At the same time, it is covered with adhesiv...

Problems solved by technology

The process is manufactured separately in multiple production lines or multiple manufacturers. The finished fiber cotton product has been circulated many times. Due to the influence of environment, storage, humidity, etc., its fluffy structure and insulation performance are destroyed, which affects the quality of sound absorption and heat insulation. At the same time, it is covered with adhesive treatment and transfer costs are higher
