Automatic production equipment for 3.2-meter wide non-woven fabrics

Abstract

The invention relates to the technical field of non-woven fabrics, in particular to manufacturing equipment for the non-woven fabrics. The equipment is controlled by the program of a programmable logic controller (PLC) and comprises a feeding unit, a screw extruder, an extension box body, an airflow drafting unit, a cooling side-blowing unit, a wet forming unit, a rolling mill and a winding unit, wherein the screw extruder is used for extruding raw materials by heating; a filter is arranged at the extrusion port of the screw extruder; the input end of the extension box body is connected to the filter through at least two counters which are connected in parallel; the airflow drafting unit is in vertical butt joint with the output end of the extension box body; a single body drawn by the extension box body is intertwined and staggered by the airflow drafting unit; the cooling side-blowing unit is arranged on the side of a single body drafting region between the extension box body and the airflow drafting unit; and a regulating valve capable of regulating air quantity is arranged on an air channel of the cooling side-blowing unit. The equipment can produce 3.2-meter wide non-woven fabrics, meets new state requirements of non-woven fabric industries and has a simple, scientific and reasonable structure.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to non-woven fabric manufacturing equipment. Background technique [0002] Non-woven fabric, also known as non-woven fabric, is composed of directional or random fibers. It is a new generation of environmentally friendly materials. Low cost, recyclable and so on. Thermoplastic materials are used as raw materials, such as polypropylene (pp material) pellets are used as raw materials, and it is produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. [0003] At present, the general spunbonded non-woven production line has a low level of intelligence in the control of the production line, and most of them adopt semi-automatic control. The adjustment of process parameters is inconvenient, and there are many opportunities for human error. All control parameters cannot be centrally controlled, nor can it be realized. On...

Problems solved by technology

[0004] The development of non-woven equipment in my country is relatively late. From the late 1980s to the early 1990s, it was the climax of a large number of imports of non-woven equipment in my country. By the mid-1990s, my country's non-woven equipment manufacturing industry had formed a combination of non-woven special equipment. Production line, the main technical advantages are divided into two categories: imitation of Italian technology and imitation of West Germany technology, but the manufacturing level of domestic non-woven machinery and equipment is far from the level of similar equipment in the world, basically in the middle and low level; especially for production The equipment of wide-width non-woven fabrics has low efficiency, low product uniformity, water permeability resistance, strength, and hand feeling in production operations.
