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.

The HN800 series eddy current sensor is a combination of a preamplifier and an eddy current probe. It is a non-contact linearized sensing system. The eddy current sensor is mainly used to measure the static and dynamic distance between the probe and the measured object. The object to be measured is generally ferrite. The alternating electromagnetic field of the probe is absorbed by the ferrite. The electronic circuit of the sensor senses and processes the change. Thereby, the displacement amount of the measured object is obtained. It has the advantages of long-term work reliability, wide measuring range, high sensitivity, high resolution, fast response, strong anti-interference ability, and no influence from oil and other media. Therefore, HN800 series eddy current sensor monitors on-line condition of large rotating machinery. Widely used in troubleshooting.
Axial position measurement: It indicates the possibility of wear of the thrust bearing or potential bearing failure.
Radial vibration measurement: The HN800 series eddy current sensor can indicate the working condition of the bearing and can detect mechanical faults such as rotor imbalance, misalignment and shaft crack.
The average radial position of the shaft in the bearing: it can be used to determine the azimuth, which is also an indication of whether the speed is stable and the shaft is centered.
Key phase signal: It is used to measure the rotational speed of the shaft and the phase angle.
Eccentricity: For large and small turbomachines, the shaft bending, ie the eccentricity, needs to be measured at start-up.
The SH06 eddy current sensor calibrator sensor is mainly used to measure the static and dynamic distance between the probe and the measured object. The object to be measured is generally ferrite. The alternating electromagnetic field of the probe is absorbed by the ferrite, and the electronic circuit of the sensor is sensed. And the amount of change is processed, thereby obtaining the displacement of the measured object, the displacement of the rotating mechanical shaft system, the vibration, the rotational speed, the expansion, the eccentricity, the oil film thickness on-line monitoring, the mechanical size, thickness, and surface roughness detection of the product.
The limit, counting and other precision control of industrial process automation can be widely used in petrochemical, metallurgy, steel, electric power, aerospace, pharmaceutical, machinery manufacturing and other industries.
The sensor can dynamically and non-contactly measure the relative vibration displacement (such as shaft vibration, etc.) of the metal conductor to be tested and the end face of the probe.
The sensor can measure the relative displacement (such as axial displacement, differential expansion, etc.) of the metal conductor to be tested and the end face of the probe in a static and non-contact manner.
In engineering vibration, the operating state and operational failure analysis of rotating machinery and reciprocating operating machinery, using vibration monitoring is an authoritative method of Zui, which has a time-reality. The imbalance of the rotor, the misalignment of the two connected rotors, the bearing wear, the shaft cracks and the dynamic and static friction of the rotor blades with the casing are mainly reflected in the changes in the amplitude, phase and frequency of the vibrations. It is the key information of Zui and it is easy to measure.
The eddy current displacement sensor has long-term high reliability, non-contact measurement, strong anti-interference ability, is not affected by medium such as oil and water, and has wide application range and simple structure. It is often used for long-term real-time monitoring of shaft vibration, axial displacement, shaft speed, housing expansion, etc. of large rotating machinery, and effectively protects the safe operation of equipment. Trend analysis and fault diagnosis of monitoring data can also be performed to predict maintenance and troubleshooting.
