Structure principle and precautions of meltblown non-woven fabric production equipment

Non-woven fabrics are the upstream products of the mask industry. No non-woven fabrics can be found, and mask machines are also difficult to cook without rice. For a small-scale single-layer meltblown non-woven production line, non-woven manufacturers will spend more than 2 million yuan, and the price of three layers is higher, costing more than 7 million yuan. It will take at least two or three months to debug. In the event of a breakdown, apart from the cost of lost raw materials, heating, water and electricity costs, and workers’ lost work costs, the working capital of the factory will still miss the golden production time and cause losses. After the meltblown non-woven equipment fails, you should contact a professional maintenance team to deal with it in time. Time is money. The shorter the time to find a professional maintenance team, the lower the loss.

Melt-blown non-woven fabrics are different from the traditional spunbond production. It uses high-speed hot air to stretch the polymer trickle from the spinneret holes of the module to become An ultra-fine short fiber is produced, which is guided to the roller to cool and form by its own adhesive force.

Its production process is a flow process, from the unloading and unloading of polymer materials to the melting and extrusion of materials, through the metering of the metering pump, using a special spinneret module to spray out , the high-speed hot air stream can reasonably stretch and guide the polymer trickle from the spinneret hole. After cooling, it is formed on the roller, and the material is received and processed at the lower end. , to find problems in time and solve them in a timely manner.

The production line of melt-blown non-woven fabrics includes many single equipments, such as the feeding machine for feeding the polymer, the screw extruder, the metering pump device, the spinneret module, the heating system, the air Presses and cooling systems, receiving and winding units. These devices work alone, under the joint command of plc and industrial computer, etc., to establish a synchronization and tension control system, which is useful for inverters to control extrusion, transmission, winding, etc., as well as temperature control systems to control heating, the inverter will still Controls fans and cooling, etc. At present, the domestic spinneret module cannot achieve high precision, and needs to be imported from abroad, while other accessories can be produced in China at present, and the maintenance efficiency will be higher accordingly.

Some mechanical problems are easy to find and solve. For example, if a certain drive roller bearing is broken, there will be abnormal noise, and it is easy to find suitable accessories to replace. Or the reducer of the screw is broken, which will obviously cause speed fluctuations and loud noises.

However, for electrical problems, if a fault occurs, it is relatively hidden. For example, a certain contact of the PLC is broken, which will cause abnormal linkage. A certain drive optocoupler of the inverter is abnormal, causing the three-phase current of the motor to fluctuate greatly or even stop due to lack of phase. The parameters of the winding tension cannot be matched well, which will cause the winding to be uneven. Or a certain line leaks, causing the entire production line to trip and fail to start.

The touch screen touch glass, due to excessive pressing, or dust and grease running on the inner cable head, lead to poor contact or aging of the touch panel, resulting in ineffective pressing or failure, all need to be dealt with in time.

PLC is usually less broken, but it does not mean that it is not easy to break. Usually, most of the contacts and power supply are burned. It is simple and quick to deal with the corresponding problems. If the program is lost or the motherboard is faulty, it will be The entire production line was paralyzed, and it was necessary to find a professional company in time to help solve it.

Inverter and tension control system, because the power used on this type of equipment is relatively large, if the site does not pay attention to cold cutting and dust removal, it is easy to stop due to high temperature and static electricity in the production process .
