1. Finishing sensor: Clean the detector cover regularly (once every four hours). When the machine is running, ensure that the white light is always on. The detector is designed according to the infrared principle. Dazzling light will affect the performance of the sensor. Try to use only daylight tube near the machine. If the spindle surface is bright, the detector may not work accurately. Avoid using aluminum tube or black tube. Black yarn will make the detector unable to work.
2. Weft breaking sensor: during the normal operation of the circular loom, when the weft is broken due to external force, the sensor detects the signal and transmits it to the controller to control the circular loom to stop. if the weft is broken, the machine cannot stop automatically: jog the machine to run the guide tube of one of the shuttles below the sensor, and manually and quickly tear the weft to make the steel ball enter the detection range of the sensor. if the red indicator light of the sensor, the position of the sensor should be adjusted until the red indicator light comes on or the sensor should be replaced.
3. Main speed detection sensor: During the normal operation of the machine, if the frequency conversion frequency is increased, it may be that the sensor misses the detection of the main engine due to vibration. At this time, it is necessary to adjust the position of the sensor to align the head of the sensor with the gear plate, and then observe the frequency conversion frequency increase. If the frequency conversion frequency is increased, the effect cannot be achieved after many adjustments. Replace the sensor.
4. Raise the detection sensor: If the man-machine interface cannot accurately record the output, check whether the wiring is correct, if the wiring is correct, adjust the position of the sensor, run the machine, and observe whether the indicator light flashes, if not, consider replacing the sensor.

Finishing sensor: clean the detector cover regularly (once every four hours). When the machine is running, make sure that the white light is always on. The detector is designed according to the principle of infrared ray. Dazzling light will affect the performance of the sensor. Try to use only daylight tube near the machine.

A variety of materials with different characteristics are compounded to improve the air permeability, moisture permeability, oil resistance, water resistance, and chemical resistance of packaging materials, so that they can play an insect-proof, dust-proof, microbial-proof, light, fragrance, and odor Isolation, as well as heat resistance, cold resistance, and impact resistance, have better mechanical strength and processing applicability, and have good printing and decoration effects.
What are the classification of bags?
Plastic packaging bags include plastic woven bags and plastic film bags. The former has the characteristics of light weight, high strength, corrosion resistance, etc., after adding plastic film lining, it can be moisture-proof; light bag load weight below 2.5kg, medium bag load weight 25-50kg, heavy bag load 50-100kg.
The national standard GB/T8946-1998 stipulates that "the bag shall be flattened, and two squares of 100mm × 100mm shall be circled at the upper and lower diagonals of the bag. the outer edge of the square shall be 100mm apart from the edge line of the bag. the longitude and weft number of the squares shall be visually inspected and the average value shall be taken. when counting, when there is less than one ending point, it shall be counted as one." The national standard specifies the density of weaving and the density tolerance. The weaving density mainly depends on the packaging product and is determined by the user.
Due to product resources and price problems, China has 6 billion woven bags for cement packaging every year, accounting for more than 85% of bulk cement packaging. With the development and application of flexible container bags, plastic woven container bags are widely used in marine, transportation and packaging of industrial and agricultural products. In the packaging of agricultural products, plastic woven bags have been widely used in aquatic products packaging, poultry feed packaging, covering materials for farms, sunshade for crop planting, windproof, hail shelter and other materials. Common products: feed woven bags, chemical woven bags, putty powder woven bags, urea woven bags, vegetable mesh bags and other fruit eye bags, mesh bags
Standard for wire drawing machine
Surfacing wear-resistant plates can be used in various loading and unloading equipment and sites, especially in bulk cargo loading and unloading systems such as iron ore and coal, grab bucket, hopper, bucket, coal drop pipe, discharge pipe, stacker-reclaimer and other components. These components often need to bear a large amount of impact, wear and friction. Surfacing wear-resistant composite steel plates are used in easy-to-wear parts, which is very important for prolonging the service life of these wear parts and reducing the downtime and maintenance of loading and unloading machinery.
