The Core Reason for Small Openings: Insufficient openings at the front of the jacquard machine faucet are like a singer with their throat choked-they simply can't sing high notes. Common causes include:
Heald frame height misalignment: The lifting stroke does not reach the design value.
Overly dense heald threading: The warp yarn spacing is excessively compressed.
Wear of linkage mechanism: There is a gap between the jacquard head and the heald frame connection.
Three-step emergency solution: Don't rush to call a repairman in this situation; you can fix it yourself:
Adjust the lifting rod: Loosen the fixing nut and raise the entire heald frame by 2-3mm, ensuring it is level.
Reorganize the heald threading sequence: Use a "skip-one" method to allow the warp yarns room to spread.
Lubricate joints: Apply silicone-based grease to the contact points between the jacquard rope and the pulley.
Preventive maintenance tips: The secret to keeping the equipment in good condition:
Check the sheath clarity weekly; it should be ≥10mm when measured with a ruler.
Clean the jacquard needle plate monthly to prevent lint buildup from affecting the accuracy of the operation.
Replace worn nylon guide wheels quarterly to prevent play.
Conduct a small-scale test on new fabrics first to confirm the sheathing effect before mass production.
