The melt blown non-woven fabric production line includes many individual equipment, such as a polymer feeding machine, screw extruder, metering pump device, spray hole mold group, heating system, air compressor and cooling system, receiving and winding device. These devices work independently and are jointly commanded by PLCs and industrial control computers, forming a synchronous and tension control system. They are used to control extrusion and transmission, winding, etc. with frequency converters, as well as temperature control systems to control heating. The frequency converter also controls fans and cooling, etc.
The principle and composition of melt blown non-woven fabric production line
Meltblown non-woven fabric is different from traditional spinning and sticking methods in that it uses high-speed hot air flow to stretch the polymer stream sprayed from the nozzle holes of the module, turning it into an ultrafine short fiber that is guided to the roller for cooling and formed by its own adhesive force.
Its production process is a streamlined process, from the loading and unloading of polymer materials, to the melting and extrusion of materials. After being measured by a metering pump, a specialized spray hole mold group is used to spray out the polymer. The high-speed hot air flow stretches and guides the polymer trickle from the spray hole reasonably, and after cooling, it is formed on the roller and received and processed at the lower end of the material. Any problem in any link may cause production interruption. It is necessary to detect and solve the problem in a timely manner.
Attention to maintenance of melt blown non-woven fabric production line equipment
At present, the domestic nozzle mold group cannot achieve high precision and needs to be imported from abroad, while other accessories can already be produced domestically, and the efficiency of maintenance will be relatively higher.
1. Some mechanical problems are easy to detect and solve, such as a broken transmission roller bearing that makes abnormal noise, and it is also easy to find suitable parts to replace. Or if the reducer of the screw is broken, it will obviously cause speed fluctuations and make loud noises.
2. However, for electrical problems, if there is a malfunction, it is relatively concealed. For example, if a contact of the PLC is broken, it can cause abnormal linkage. One of the drive optocouplers of the frequency converter is not working properly, causing severe fluctuations in the three-phase current of the motor and even shutting down due to phase loss. The parameters on the winding tension are not matched properly, which can cause uneven winding. Or a leakage in a certain line may cause the entire production line to trip and fail to start up.
3. Touchscreen touch glass, due to excessive pressing or dust and grease running onto the wiring heads inside, causing poor contact or aging of the touchpad, resulting in ineffective or ineffective pressing, all need to be dealt with in a timely manner.
4. PLCs are generally less prone to failure, but that doesn’t mean they won’t break. They tend to burn contacts and power supplies, making them easier and faster to handle. If the program is lost or there is a problem with the motherboard, it can cause the entire production line to malfunction, and it is necessary to promptly seek help from a professional company to solve the problem.
5. Frequency converters and tension control systems, as they require relatively high power, can easily shut down during production due to high temperatures and static electricity if cold cutting and dust removal are not taken into account on site.
