The path of producing jacquard textiles has been a long and torturous one, beginning with entirely manual manufacturing, progressing through mechanical jacquard machines, and finally to today’s electronic jacquard machines. Here are some critical facts concerning electronic jacquard machines that you should be aware of.

(1) The electronic jacquard machine’s control basis

Electronic jacquard shedding combines microelectronics, electromagnetics, and photoelectrics. The collaboration of a textile CAD system with a novel mechanical mechanism enables the production of high-speed non-pattern jacquard, significantly increasing labor efficiency and product quality. The electronic jacquard control part’s design concept utilizes a general-purpose microcomputer or industrial computer as the control body, data sources in the form of disk files, network files, etc., and appropriate interface circuits to read jacquard information and create timing sequences. To execute the jacquard control, the jacquard information is driven and transmitted to the jacquard faucet.

At the conclusion of World War II, worldwide research on electrical jacquard machines started. The use and development of large-scale integrated circuits and electronic computers accelerated the advancement of research on electronic jacquard machines in the 1970s.

In 1983, during the Milan Textile Machinery Exhibition, the first electronic jacquard machine was displayed as a prototype. Since then, other makers of jacquard machines have incorporated it in their growth plans. Since the 1980s, the textile sector has prospered, with a highly positive growth trajectory.

In comparison to mechanically operated jacquard machines, electronic jacquard machines provide more creative pattern control options. Although the architecture of various electronic jacquard machines vary, they always consist of the following components:

  1. Electronic program-controlled device: transmits complete information accurately and includes keyboard, display, and printing features;
  2. The mechanism for converting electrical signals to mechanical quantities: in most cases, electromagnets are utilized; that is, the entire information given by the program control device is translated to mechanical displacement in order to achieve mechanical control.

(2) The electronic jacquard control system’s composition

  1. Jacquard data disk: used to store jacquard data.
  2. Host: 80286 or above may utilize a microcomputer or industrial computer for reading jacquard information, transferring disk information, reporting faults, and managing man-machine interfaces.
  3. Control interface: this interface is used to process and convert jacquard data.
  4. Power-off memory interface: utilized to store technical management information and production statistics on a long-term basis.
  5. Interface board: utilized for transfer of jacquard information and hardware protection.
  6. Jacquard drive card: used to pick needles and regulate warp.
  7. Integrated power supply: It utilizes both decentralized and solid power supply modes for the jacquard faucet’s power supply.
  8. Sensors: Various problems such as warp breakage, weft breakage, and other signals are gathered, sent to the host, and dealt with appropriately.

(3) Information on the human-machine interface and control

The electronic jacquard control part’s human-machine interface supports both English and Chinese directions that are succinct and clear, simple to use, and very pleasant. The whole human-machine interface is divided into three sections, each of which is represented by a huge color font menu.

  1. Loom in operation: After choosing it, the page will show all *EP jacquard files saved on the hard drive (optional), and the chosen file will be woven by dragging the color prompt box.
  2. Signal test: comprised of two sections: control signal and driver card. It enables consumers and maintenance professionals to easily locate issues. The control signals comprise the clock signal CLK, the pull-in open OE, and the storage allow STB. It is easy and practical to conduct the driver card test by entering the serial number of the driver card to be tested at the prompt.
  3. File management: When this option is chosen, the system reverts to the DOS environment, allowing users to conduct operations such as picture file copying, file deletion, and disk formatting with ease.
  4. Data entry for jacquards

The jacquard information is extracted from the patterning CAD system’s *EP file. The disk file is used to store the jacquard data, and the floppy disk drive of a standard microcomputer is used to access it. The file transmission is straightforward and uncomplicated. The jacquard data may be sent directly from the design office’s CAD system to the mainframe of the jacquard control system.

  1. Interfaces for control and information translation

The control interface’s primary function is to read the jacquard loom machine‘s working stroke information (information on the transmitting plate) and fault information (warp thread break, weft thread break, power abnormality), which it will gather and handle in a timely way. For instance, the control subject determines when to transfer jacquard data to the jacquard faucet based on the journey information and manages different abnormal circumstances appropriately. Because the appearance of these signals is irregular and bursty for the control subject, the interface makes extensive use of the microcomputer’s interrupt mechanism to resolve this random bursty information, therefore achieving normative closed-loop control.

(4) Information about jacquards is sent and executed

  1. Electromagnetic board principle

The jacquard information is sent to the jacquard faucet through serial distribution and long-term transmission via the interface board, with a transmission distance of up to 40m, and then to the jacquard faucet’s electromagnetic valve plate.

The interface card distributes the jacquard data and control information provided through the long line to the solenoid valve plate. After the data is serially sent to each solenoid valve plate, the synchronous parallel output controls the jacquard loom’s up/down movement in response to the control signal. Control of the descending warp thread, which weaves the map of each shuttle in real time according to the jacquard data.

2.Mechanical force is converted from electromagnetism.
