How To Adjust The Needle Spacing Of The Old Round Nose Lock Machine

For the commonly used round nose keyhole machines in the market,

I analyzed the problem before adjusting it.

This time, mainly for the old section of the round head keyhole machine adjustment problem analysis, hoping to help everyone.

Now, taking the 101 button eye lock machine as an example, the adjustment method of the stitch density is to unscrew the needle pitch adjustment nut of the round head keyhole machine, and move the ratchet drive lever along the ratchet adjusting slot forward or backward.

If you move forward (toward the operator's direction), then the stitch is encrypted, and the back trace is thinned.

After adjusting the stitch density of the round head keyhole machine, we must tighten the needle adjusting nut.

In addition, the stitch density of the round head part of the Nu hole is consistent with the stitch density requirement of the pverse section of the hole, otherwise, the appearance of the hole will be affected.

The stitch density of the round head can be adjusted by changing the position of the center pin when the hole is locked.

Encrypt or reduce the round head.

We can unscrew the needle of the needle seat, push the needle seat forward, and the number of pins in the round head can be encrypted, and push back further, so the number of needles is reduced.

When a round head lock machine is used to lock holes in the small round head, if the number of pins in the small round head is too dense, we can push the needle seat back to the bottom.

If this adjustment is made,

The number of needles is still too dense, so we can push the two level tube wrench and the two level cam wrench in the corresponding direction of the round eye keyhole machine, and develop the control system on the basis of the HT-8850A multi-function double needle pattern machine, which is famous for the production of the bead sewing machine. The system can be programmed on the basis of the 100 basic patterns and can pform various decorative stitches on the basis of the touch screen.

The density of the small round head can be thinned.

Of course, if we need to lock the large round head hole, we should pull the two level wrench and the two level cam wrench back to the corresponding direction.
