Some components of the high-speed knitting machine, such as the spindle support frame, sliding seat, etc., must ensure the accurate distance between the sliding seat and the lower spindle braiding line after maintenance and disassembly or when adjusting and reinstalling new parts. It is recommended to first place a sliding frame and the attached upper spindle to run on the sliding wheel so that when the lower-weight braiding line is led from the swing rod to the braiding point, it will not be hooked or disconnected by the sliding frame.
During rough adjustment, put the spindle on the two adjacent outer spindle supports, guide the braided wire to the braiding point according to the swing rod, and stack it tightly. When the braided wire enters or exits the slot on the sliding wheel track, its distance to the edge of the upper spindle sliding frame must be basically the same. The adjustment of the distance can be accomplished by switching the gear rack forward or backward by one or more gears.
If you cannot adjust the distance accurately by moving one tooth, you can adjust it according to the following steps: Loosen the five fixing screws on the internal gear. Since the buried hole is oval, you can complete the sliding frame by moving the internal gear. Adjustment, adjust in time, and tighten the screws. Place the other sliding frames evenly on the sliding circular track. If the swing height of the braided wire is different after the new swing bar is installed, it should be adjusted so that all the swing bars have the same endpoint.
When high-speed knitting machinery is manufactured, the equipment is in operation for a long time, and the static deformation and dynamic deformation of the equipment will change all the time, which causes local deviations and system deviations of the parts that have been tightened or connected slowly. Increase. Eventually, the relative spatial position of some parts will be moved, and the process distance will change, resulting in a change in the process state and a decrease in product quality.
Regardless of whether the device is running or not, its static data always exists. After operation, the dynamic deformation is increased. These two deformations deform the threads of the screw nut and the screw rod, causing the connection to gradually loosen, the washer to become soft after being squeezed, and the elasticity of the self-locking nut to decrease.
Use safety inspections to check whether the key process components and tightening connections of each piece of equipment are loose, and tighten loose parts in time. Purchase standard tightening couplings from designated factories in my country. Unify the tightening procedures of standard parts to minimize under-tightening or over-tightening, which may cause potential failures or reduce the service life of tightened parts.
