Q: What are the daily applicable materials of Ultrasonic Fabric Machine?
A: Lace ribbons, various decorations, handkerchiefs, table cloths, curtains, bedspreads, pillowcases, quilt covers, tents, raincoats, gloves, disposable surgical clothes, disposable masks, disposable sanitary products, non-woven cloth bags, etc.
Q: What processes can be realized by ultrasonic lace machine?
A: Ultrasound is now winning more and more acclaim in the textile and non-woven industries. Textile ultrasonic sewing machine has good applications in lamination, bonding, embossing, cutting and perforation.
Q: What should I do if the solder joint is not clear when sewing the non-woven fabric material (it will be broken once torn)?
A: Adjust the pressure of the pressure regulating valve. (increase or decrease); Adjust the amplitude of the ultrasonic generator (increase the amplitude can improve).
Q: What should I do if there are wrinkles when sewing double-layer fabrics?
A: Adjust the relative speed difference between the upper and lower wheels of the machine. The problem can be improved by adjusting the two speeds as much as possible.
Q: What should be done if the welding spot is penetrated during welding?
A: Reduce the amplitude of the generator. Or reduce the pressure of the machine.
Q: What if the welding spot is not clear (not welded firmly) when accelerating the speed?
A: Increase the pressure and adjust to the appropriate speed. Or increase the amplitude of the generator.
Q: What should I do if there is bad welding when replacing the new cloth?
A: a.check whether the chemical fiber content of the cloth can be welded by ultrasonic wave. b. Check that the thickness of the cloth is the same as before. c. Replace the flower wheel (different flower wheels have different patterns). Different welding effects can be obtained by replacing different flower wheels. d. Check the gear tooth depth, pressure and ultrasonic amplitude.
Q: Is the welding effect of the lace machine related to the specification of the non-woven fabric?
A: The thickness of the non-woven fabric determines the design of the flower wheel. We generally support the welding of the fabric within the specification of 120g. The heavier the fabric specification, the slower the welding speed and the stronger the pressure required.
Q: How to install the flower wheel?
A: a.Press the emergency stop key or step on the foot (the flower wheel will rise automatically for easy disassembly); b. Loosen the locking screw of the original flower wheel and remove the flower wheel, align the new flower wheel with the mounting hole, and lock the fixing screw at the same time.
Q: How to control the flower wheel pressure?
A: a.check whether the air pressure is above 0.4MPa; b.Whether the limit is reasonable; c.The sound wave amplitude of the steel mold is small, and the pressure can be increased;for materials with high chemical fiber content (such as nylon), the pressure can be reduced, whereas for TC cloth, the pressure can be increased; d. For thick materials, the pressure can be increased; e. Under the premise of the same quality and the same processing speed, the smaller the pressure of the flower wheel, the better (the smaller the pressure, the less the wear of the steel mold and the flower wheel, and the longer the service life of the equipment).
Q: How to judge whether the flower wheel can be used normally?
A: The pattern of the flower wheel must be kept sharp, with a hardness of hrc60-61 °. The worn and rusted flower wheel shall not be used to avoid affecting the product quality, or the increased pressure of the flower wheel may cause the accelerated wear of the steel mold.
Q: What are the relevant precautions for the Ultrasonic Fabric Machine?
A: a Avoid dusty, corrosive, high-temperature or humid working environment; b. Power three pin plug, live wire L, neutral wire n and ground wire g must be reliably grounded during use; c. When connecting the equipment with the power supply and air source, pay attention to turning off the power switch first; d. If the voltage fluctuates greatly, a voltage regulator should be installed e. The steel formwork shall be inspected regularly; f. For operators with low proficiency, the speed should be adjusted slowly at the beginning to ensure safety; g. Check before each use by turning on the power switch and pressing the "audio detection" switch. If one of the following phenomena occurs, the frequency shall be corrected: ● touch the working surface of the steel mold with your hand and feel the weak ultrasonic vibration; ● abnormal noise; ● the die head is abnormally hot; ● the reading of ammeter on the generator box exceeds 1.2A. h. The ultrasonic generator in the generator box is sensitive to the input voltage. If the voltage fluctuates greatly, a stabilized power supply must be installed;
Q: How to maintain the Ultrasonic Fabric Machine?
A: a.Vibration box: ● Ultrasonic inspection: when the steel mold is not installed, the indication of the ammeter shall not exceed (0.4A); ● Check the switch according to the method: press 2 seconds to stop for 1 second within 3 seconds. Do not press for more than 3 seconds continuously to avoid shortening the life of the transducer and burning the electronic components; ● Avoid dust, metal, etc. falling into the generator box to avoid short circuit and damage to the circuit board; ● Keep air circulation and good heat dissipation. b. Device host: ● The main machine shall not be placed in high temperature, humid and dusty environment; ● Do not place liquid on the main machine, keep it clean, and do not use liquid for cleaning when wiping; ● If it is used for more than seven days or sparsely, please cover it with a dust cover; ● When it is not used for a long time, it must heat up the engine once a week; ● Pay attention to the cleaning of the air pressure source. If 1 / 2 of the water is retained, it should be drained in time; ● Except for necessary maintenance, try to avoid opening the machine body. When opening, be sure to unplug the power supply and release the residual power in the capacitor. ● The moving parts shall be regularly filled with lubricating oil to reduce wear between hardware. c. Steel formwork: ● Knocking or damaging the steel mold, which is easy to change the vibration frequency; ● The steel mold shall be protected from oxidation and rust, and shall be wiped with oil cloth and sealed when not in use; ● When installing the steel mold, the bottom thread shall be clean; ● The ultrasonic steel mold is specially designed and matched with a fixed frequency. It is forbidden to cut, drill or change any appearance, otherwise the service life of the transducer and the generator box will be affected; ● When loading and unloading the steel mold, it must be handled with care to prevent the thread of the steel mold of the luffing rod from slipping.
Q: How to install the newly purchased Ultrasonic Fabric Machine and what should be paid attention to?
A: a Please read the instructions carefully first; b. Disassemble the packaging, check whether the surface and parts of the equipment are damaged, check whether the screws are loose, whether the electrical connectors are locked, and whether the accessories are complete; c. Check the voltage requirements of the label on the back of the vibration box and ensure that the system is well grounded; d. Connect the equipment with the power supply and air source, and pay attention to turning off the power switch first; e. The air pipeline is connected to a clean and lubricant free compressed air source with a rated working pressure of 0.6MPa; f. Ensure that the air source connected to the equipment is dry gas, and ensure the service life and normal use of the equipment.
