The electronic jacquard faucet is the core component of the electronic jacquard machine, responsible for accurately controlling the lifting and lowering of warp yarns according to control instructions to form fabric patterns. Its structure is complex and precise, mainly including the following key parts:
1. Needle bed and warp needle
Needle bed: arrange warp needles according to the number of warp yarns, and each warp needle corresponds to one warp yarn or a group of warp yarns. The needle bed is the carrier of the needle, ensuring that the needle can work stably and accurately.
Thread: Thread is a key component for performing the needle selection action, and its lifting state determines the lifting of the warp yarn.
. The design of the needle needs to consider strength, wear resistance, and accuracy to ensure stability under long-term high-speed operation.2. Knife pushing system and needle selection logic
Knife pushing system: composed of several knives, it cooperates with the needle to achieve needle selection logic.
. The movement of the blade is controlled by an electromagnet or servo motor to ensure that the needle can be accurately raised and lowered according to instructions.Needle selection logic: According to the instructions sent by the control unit, the blade pushing system selectively drives the needle to rise and fall, forming a specific pattern.
. The accuracy of needle selection logic directly affects the quality of fabric patterns.III. Electromagnetic array or servo motor group
Electromagnetic array: driven by electromagnetic force to lift the needle or control the displacement of the blade.
. The layout density of the electromagnet determines the number of stitches (i.e. the maximum width of the pattern) of the jacquard machine. Electromagnets need to have the characteristics of fast response, high precision, and long lifespan.Servo motor group: Some high-end electronic jacquard faucets use servo motor groups instead of electromagnetic arrays, which achieve precise lifting and lowering of the needle by precisely controlling the rotation angle and speed of the motor.
. The servo motor group has higher control accuracy and flexibility, suitable for the jacquard requirements of high count and high-density fabrics.IV. Mechanical Structure and Transmission Components
Mechanical Structure: The mechanical structure of electronic jacquard faucets needs to balance strength and accuracy, usually using aluminum alloy or high-strength engineering plastic shells, and the internal transmission components are precision machined.
. The design of mechanical structures needs to ensure stability during long-term high-speed operation and reduce vibration and noise.Transmission components: including pulleys, eccentric wheels, connecting rods, etc., used to convert the rotational motion of the motor into linear motion of the pusher or needle.
. The design of transmission components should ensure smooth and reliable movement, reduce energy loss and wear.Fifth, Control Interface and Signal Transmission
Control Interface: The electronic jacquard faucet is connected to the control unit through the control interface, receiving control instructions and providing feedback on the working status.
. The control interface needs to have high-speed and stable data transmission capabilities to ensure accurate execution of instructions. Signal transmission: Control instructions are transmitted to the drive module of the electronic jacquard faucet through a bus (such as RS485, CAN bus, or industrial Ethernet). The accuracy and real-time performance of signal transmission are crucial for the pattern quality of fabrics.VI. Auxiliary Components and Functional Modules
Auxiliary components: such as springs, pulleys, guide rails, etc., used to assist the movement of the needle or blade, ensuring the smoothness and accuracy of the movement.
.Function modules: Some high-end electronic jacquard faucets also integrate visual inspection modules, fault diagnosis modules, etc., which are used for real-time monitoring of warp yarn status, feedback adjustment of jacquard parameters, or diagnosis of equipment faults, improving production stability and equipment maintenance efficiency.
