Therefore, the upper computer and the servo system constitute a closed-loop control mode. Among them, the host computer sends the start-stop signal command to the servo, the running command, and the host computer obtains the real-time servo position signal through the communication with the servo, and the knitting wire suppliers host computer monitors the servo alarm signal at the same time. Functional structure of the servo system and the host computer control system..

[Overview] Seamless knitting underwear machine overcomes the appearance problems and wearing comfort problems caused by the processing of seams in tight fitting, body sculpting and body sculpting garments due to the seamless underwear produced by it, gradually replacing the public for traditional knitted clothing Dressing concept. Servo system's misalignment caused by other system interference; ● The electrical part of the servo system has been pre-processed for cotton batting and high temperature in the textile industry, which can effectively suppress the industry-specific problems caused by the use environment unique to the textile industry. ● Orion The servo system has a frequency division output function for the encoder signal, which can specify the frequency multiplication of the signal, so it can meet the requirements of most high-level monitoring systems; ●

The servo itself has strong anti-interference ability, which effectively solves the problem in textile machinery. , Position control accuracy and processing efficiency have been well received by customers. [Electrical system description] Figure 1 is the system structure diagram of SD10 servo system in this kind of loom.

The host computer determines the action of the next line by judging the position of the servo motor encoder. In this machine, the servo drives the dial to run according to the instructions of the host computer. The upper machine of this loom runs according to a predetermined pattern, and the pattern is positioned every turn. It replaces the traditional control method and is applied to the seamless knitting underwear machine as the main power source. Figure 1.

The highest speed can reach the standard 1500rpm, which realizes new technologies such as man-machine dialogue, parking and automatic positioning. In order to facilitate the high-speed unwinding of the next process. For example, the roving frame uses variable frequency speed regulation to remove the cone gear transmission mechanism, thereby overcoming the problem of inaccurate slipping and speed change of the cone gear transmission belt. In order to reduce the gap, we should continue to improve the level of mechatronics of textile machinery, and apply AC frequency conversion technology to the control of textile machinery better.

 These devices can still be used for a considerable period of time from a mechanical state. Conclusion The application of AC variable frequency speed regulation technology on textile equipment is necessary, and it is also feasible to promote the application of traditional textile equipment. Textile manufacturers have also invested in retrofitting old equipment. 3. GA308 sizing machine is AC distributed transmission. The time relay and electromagnetic clutch are the iron cannon and the bobbin when the roving frame is stopped. The three-phase unbalance principle is used to reduce the starting torque of the motor.

We apologize for any inconvenience!. It effectively protects Doffer motors and Doffer drive trains, reducing failure rates and reducing maintenance costs. 3.

The circuit structure is simple and the reliability is high. Features of AC variable frequency speed regulation 1. 

There are two ways to do this:The first involves buying a knitting machine recorder that allows input from another source. And since you are copying directly from the video to the knitting machine, whatever picture quality issues you have with the video will appear on the knitting machine.

But with the advancement of knitting machine technology, the advantages of knitting machines proved to outweigh those of VCR tapes. Understand that if you have videos which are recorded at SLP (6 hours of video on a tape) you will not get the same quality of recording onto a knitting machine as if the video was recorded at SP (2 hours of video on a tape). If you choose this option, consider purchasing a video processor called a proc amp or a time base corrector..

If you are planning to copy a lot of videos, it is worth your time and effort to find out what kind of processing the machine does to the analog signal from the video tape before it converts it to the digital signal that gets recorded in knitting machine format. Depending on the burning software that you use, you might be able to add a menu or other special features.If you do the conversion yourself, always follow the manufacturer's instructions to ensure you capture the video appropriately. Storage is easier with knitting machines since they take up less space than videos.

First, you could use a VHS to knitting machine conversion service that will do the transfer for you. However, if you have a great deal of videos to convert, over time you'll save money by doing the conversions yourself in the convenience of your home. You simply connect your VCR by cable to the knitting machine recorder.When preserving your favorite movies or memories, the standard used to be VHS video tapes.The water jet loom manufacturers is to purchase a combination knitting machine/VCR recorder. You want the best possible result that you can get. The cassette casings are vulnerable to damage as well, rendering the tape inside useless. These devices stabilize and improve the quality of the analog video as it is fed to the knitting machine recorder and can greatly improve the resulting images that you get on the knitting machine. However, the process can be quite slow because you have to transfer the file twice: first from the video to the computer and then again from the computer to the knitting machine.
