Because the air-jet loom adopts microcomputer technology and other electronic detection technologies to control the movement of the whole machine, especially the automatic monitoring of product quality, the production efficiency of the air-jet loom can be greatly improved to more than 95%, and the product quality is guaranteed. The first-class product rate of the loom reaches over 98%. Many monitoring sensors are installed on the loom, so that the loom itself has the function of automatic operation and program control, forming a microelectronic automatic control system with many rotating connections. Carry out program control and quality control, and form an air-jet loom automatic control and communication network system through electronic computers. The main functions are as follows:
1. Electronic warp let-off. A sensor is installed on the warp beam breast beam, which can accurately adjust the warp tension through the electronic let-off system. In order to avoid the defect caused by turning on and off the car, it is specially equipped with a turn-on and turn off car thinning prevention system.
2. Program control of electronic automatic doffing: suitable for doffing of various weft density fabrics and large diameter cloth shafts.
3. Electronic control of weft yarn tension and warp yarn tension: under the condition of completing weft insertion, try to choose a lower jet tension and perform soft weft insertion to reduce weft yarn breakage and compressed air consumption.
4. Automatic detection system for warp and weft yarn breakage: Generally, two or more weft yarn breakage sensors are set along the entire reed width to monitor the stoppage caused by weft yarn threading failure (including weft breakage).
5. Automatic control of warp and weft yarn density and loom speed, and on-machine adjustment according to relevant information during operation.
6. Automatic weft repair and automatic winding monitoring system to eliminate unreasonable parking and ensure the normal operation of the loom.
7. Electronic weft selection and color selection (4-12 colors): according to the requirements of computer software, weft yarns of different varieties or colors are selected for weft insertion.
8. All the information of the machine is displayed on the automatic screen and various production data are memorized and stored. The digital transmission function can be connected with a private computer database to realize network information storage.
9. The electronic automatic maintenance system can automatically drive after the fault is automatically repaired.
10. Automatic process change system: the change of weft density does not need to change gears, the change of new varieties can be simplified, such as weft yarn color selection and weft density change can be completed by means of electronic control system.
11,Electronic program-controlled rapid variety change system.
12. Man-machine dialogue: The highly developed electronic technology enables the air-jet loom to operate accurately, and the operation is simplified. It can be operated by pressing the button. Man-machine dialogue belongs to the category of electronic ergonomics, and the auxiliary functions of language software are used to replace difficult Understand the human language, and carry out the program control of the machine.
13. The function of automatic inspection of fabric defects: it can check the fabric defects according to the computer system and display them in simple language. It can quickly find the fabric defects and compare them with the electronic simulation defects for classification.
14. The establishment of the electronic dobby and electronic jacquard system has greatly improved the adaptability of the air-jet loom’s color varieties. The operating speed and weft insertion rate of the electronic jacquard loom have also been greatly increased to 2800 m/min.
15. The opening and closing system of the automatic winding mechanism and the yarn winding and decoiling control system can realize the weaving middle weft yarn without joints.
In the future, the automatic control level of air-jet looms will be further developed, and the output, quality and color varieties of looms will be further improved and developed.
