Brief Introduction to the Special Opening Arm for Tsudakoma Jet Weaving Machine
The special opening arm for Tsuda Koma jet loom is an important component in the opening mechanism of the loom, mainly used to control the movement of the warp and weft frames to form a shuttle opening and achieve the interweaving of warp and weft yarns. Here is a specific introduction:
The special opening arm for Tsuda Koma jet loom is an important component in the opening mechanism of the loom, mainly used to control the movement of the warp and weft frames to form a shuttle opening and achieve the interweaving of warp and weft yarns. Here is a specific introduction:
1. Working principle: In a passive cam opening mechanism, when the opening cam rotates from a small radius to a large radius, the opening arm is pushed by the rotor, and the opening arm then pulls the steel wire rope connected to the frame, causing the frame to move from a higher point to a lower point, while the return spring is stretched and stores energy under force. When the cam continues to rotate from a large radius to a small radius, the feedback spring releases energy, causing the feedback frame to return to its original position. In the active cam opening mechanism, when the main cam rotates from a small radius to a large radius, it is driven up by the rotor swing rod, connecting rod and other components through the opening arm related components, and the auxiliary cam cooperates with the main cam to make the movement smoother.
2. Structural characteristics: The open arm is usually used in conjunction with components such as rotors and connecting rods, and its material generally has good strength and wear resistance to adapt to the working environment of high-speed operation and frequent reciprocating motion of the weaving machine. Some open arm shafts may be treated with processes such as carbon steel quenching to improve durability.
3. Function: The main function of the opening arm is to correctly move the warp frame up and down according to the requirements of the fabric structure, dividing the warp yarn that enters the warp frame into two layers to form a shuttle opening, so that the weft yarn can be smoothly introduced, and the warp and weft yarns can be interwoven to form the fabric.
4. Relationship with weaving machine models: There are multiple models of Tsuda Koma jet looms, such as the ZAX series. The opening arms of different models of looms may have differences in specific dimensions, installation methods, and structural details, but their basic working principles and functions are similar. When selecting and replacing accessories, it is necessary to determine based on the specific model.
5. Maintenance points: To ensure the normal operation of the opening arm, it is necessary to regularly check whether the opening arm and its connecting components are worn or loose, replace worn parts in a timely manner, ensure the flexible movement of the opening arm, and avoid affecting the quality and efficiency of weaving due to opening arm failure.
