Non-woven special equipment accessories
Non-woven fabric is a new type of modern material. It has a wide range of uses and can play more roles in clothing, agriculture and industry. The production of non-woven fabrics is also mostly mechanized, which makes it possible to produce a large number of non-woven fabrics in batches. Non-woven fabric winders are one of its equipment.
Non-woven fabric, also called non-woven fabric, is composed of oriented or random fibers. The production of non-woven fabrics often uses polypropylene pellets as raw materials, and is produced by a continuous one-step method of high-temperature melting, spinning, laying, and hot-pressing. In the production of non-woven fabrics, the raw materials need to be spun and formed and then processed. In the web-forming work, a non-woven web forming machine needs to be used. The web forming machine uses wind in the drafting duct to process the silk. After drafting, a machine for non-directional weaving into a net is carried out. However, polypropylene pellets are prone to broken filaments and stiff blocks during drawing, drafting, and web formation. Therefore, in order to improve the quality of the finished non-woven fabric, it is necessary to clean the formed non-woven fabric. When dealing with broken wires and stiff blocks in traditional web forming machines, workers usually use brushes or scouring pads behind the web forming machines to clean up. Because the belt width of the web forming machines is relatively long, and the conveyor belt speed is relatively high at the same time. Fast, the cleaning range that workers can cover is limited, resulting in low cleaning efficiency, which in turn affects the quality of the finished non-woven fabric.
The slitting machine is mainly used to cut large-format non-woven fabrics into multiple small non-woven fabrics of different widths for processing non-woven products. The equipment adopts DC speed regulation, feeding constant tension control, air knife slitting, rewinding pressure and other devices. The rewinding tightness after slitting is adjustable, and the slitting end surface is flat. The equipment is of high quality and beautiful appearance. It is the ideal equipment for the slitting of large non-woven fabrics. In addition, according to the needs of users, the equipment can also add a dummy cutting function, that is, the original fabric is dummy cut and then slit and rewinded.
Non-woven fabric machinery is a general term for the production of non-woven fabric products, and adopts an overall modular design with a compact and reasonable structure. The control part adopts advanced PLC microcomputer control, and the international famous brand frequency converter speed regulation.

At the press conference held in Beijing on March 19th, the “Beijing-Tianjin-Hebei Development Report (2013) published by the Social Science Literature Publishing House — bearing capacity measurement and countermeasures pointed out that traffic congestion has become a factor affecting Beijing’s urban operating efficiency and residents’ lives. The prominent problems, at the same time, the carrying capacity of Beijing's transportation infrastructure is seriously overloaded, and the traffic carrying capacity of the public transport system is saturated.
Due to the over-concentration of functions in Beijing and the “imbalance of employment and residenceâ€, the traffic pressure in the downtown area is high, and the traffic flow in the tidal area is obvious. According to monitoring by the traffic management department of Beijing, the daily number of motor vehicles driving in the Second Ring Road has reached 915,000, making the Second Ring Road the most congested area in the city. Although comprehensive slow-moving measures such as shifting peaks and commuting measures have been implemented since April 2010, with the rapid growth of motor vehicle ownership, the traffic congestion in the central urban area has been normalized from the North Fifth Ring Road to the South Fourth Ring Road, and the scope of congestion has The slow-moving sections of the road show the tendency to expand along the intercity traffic to the surrounding cities. The main causes of traffic jams in Beijing are: high population density, rapid growth of vehicle ownership, high concentration of functional areas, unbalanced development of urban areas in North and South, high concentration of high-quality public resources such as school hospitals, and large deviations in employment and residence. The low density, three-dimensional capacity of fast roads, and non-travelling vehicles indiscriminately parking and occupying roads are also important reasons.
The report believes that if we simply compare the carrying capacity of transport infrastructure, Beijing-Tianjin-Hebei ranks first among the three major metropolitan areas in China, the Yangtze River Delta ranks second, and the Pearl River Delta ranks third, while in Beijing, Tianjin, Hebei, it ranks again. First, but relative to the demand pressure of transportation facilities, Beijing's traffic capacity has been seriously overloaded. Since 2000, the number of motorized vehicles has grown rapidly (see Figure 4). The peak hour traffic volume of motor vehicles has exceeded the capacity of urban roads and the traffic carrying capacity of public transport systems has become saturated. According to the survey data provided in the “2012 Beijing Traffic Development Annual Reportâ€, at the end of 2011, the number of public-rail (electric) buses in the 6th Ring Road was 1,126,000. Assuming that all buses (electric) buses run on the road every 5 minutes, the average number of trips each bus (electric) car takes during the morning rush hour is 135, even for large buses. A crowded feeling.
