[0002] Industrial fabric loom is a very important machine equipment in the modern textile industry. It is mainly used to make fabrics and textiles. It weaves yarn into various fabrics through a series of complex mechanical principles and actions. During operation, the industrial fabric loom coordinates the operation of the weft feeding mechanism, jacquard mechanism and shuttle mechanism to achieve the orderly movement of the three basic elements of weft, warp and shuttle. The weft is initially guided by the weft feeding mechanism and is woven into the weft pattern with the help of the jacquard mechanism. After the warp and weft are interlaced, weaving is achieved through the movement of the shuttle mechanism and finally the finished product is made.

[0024] Working principle: The power of this loom comes from four motor reducer assemblies with fixed output speed ratios. The first gear 33 and the second gear 34 are added to adjust the relative positions of the active winding roller 9 and the passive winding roller 10, and the passive winding roller 10 is moved forward. The first gear 33 is fixed to the end face of the active winding roller 9, and the second gear 34 is fixed to the end face of the passive winding roller 10. The two gears are meshed and driven by the second reducer 27. The second cloth guide roller 8 is connected to the fifth reducer 32, and the outer spherical ball bearing 31 with a slider seat is fixed to the inner end face of the main wall panel 7. The squeezing roller 30 is installed with the outer spherical ball bearing 31 with a slider seat. The squeezing roller 30 is adjusted to a horizontal position by a screw rod, so that the second cloth guide roller 8 When the equipment is powered on, the four motors start at the same time, and the fourth reducer 29 on the warp feeding wall panel 18 drives the warp beam 20 to rotate clockwise, and the warp yarn wrapped thereon is slowly released and enters the weaving area through the rear beam roller 19. The warp yarn passes through the heald frame 16. One yarn can only pass through one heald frame 16. There is a flat iron pull rod under the heald frame 16. The heald frame 16 can move up and down under the control of the swing arm 25 of the multi-arm machine 17 to make the warp yarn layered. The power comes from the third reducer 28. The transmission shaft of the multi-arm machine 17 is connected to the transmission shaft of the third reducer 28 through a synchronous belt. After the warp yarn is layered in the opening part, the weft insertion box 23 is driven by the third reducer 28. , driving the sword wheel 22 to rotate, and driving the sword belt 24 wound on the sword wheel 22, the weft insertion sword head 21 fixed on the sword belt 24 clamps the weft thread, enters the inner side from the outside of the wall panel, and intersects in the middle section, the sword head at the other end clamps the weft thread to the other side, and then releases the thread end. At this time, under the rotation of the beating cam 13, the reed seat foot 14 swings, driving the steel reed 15 to push the weft thread passing through the weaving area into the cloth mouth, that is, the tip of the weaving triangle. After the finished cloth is woven, the second reducer 27 drives the active winding roller 9, driving the first gear 33 and the second gear 34 to rotate in opposite directions, and the passive winding roller 10 also rotates in the same direction as the active winding roller 9. The fifth reducer 32 and the second reducer 27 are started at the same time. The second cloth guide roller 8 rotates in the same direction as the active winding roller 9, and the squeezing roller 30 starts to rotate due to the friction force. Through the action of the winding mechanism, the cloth is sent out from the second cloth guide roller 8, passes through the bottom of the platform 6, and enters the first cloth guide roller 5 on the outer curling bracket 4. The first reducer 26 drives the active winding roller 2 to drive the passive winding roller 3 to rotate, and uses the friction force to press the cloth onto the outer curling roller 1. The outer curling roller 1 is not connected to the motor and rotates with the active winding roller 2; wherein, the breast beam 11 is used to support the heald frame 16, the reed 15 and other components to ensure their stability and accuracy during the weaving process, and the full-width side support 12 is used to keep the edge of the cloth flat to prevent the cloth from curling or wrinkling during the weaving process.
