How To Deal With The Trouble Of Jumping Needle In Old Burying Machine

Older Burying machine It may be due to near service life, every eight or nine days from day to day there will be a jump needle failure, failure is not regular. Embedding is a work name, commonly known as workshop production line, usually refers to a process, in the shirt refers to the suture side bone, in the lower part refers to the suture of external bones.

The "embedding machine" is also commonly referred to as "wrist machine", "three stitch sewing machine", "three stitch sewing machine", "arm double line loop sewing machine" and so on. It is mainly used for shirts, windbreaker, jeans, casual wear and other thin materials, medium and heavy clothing processing, and raincoats, filter bags and different cloth liners, nylon raincoats, car covers, tents, etc. And so on. Jumping needle is a common fault in sewing equipment, and the wrist machine as a professional equipment is no exception. After analysis, it is considered that the gap between the bending needle and the machine needle is too large or the needle is not synchronized with the needle; when the bending needle hook line is too small, the matching between the needle block and the machine needle is not proper, and the angle of the wire wheel is not equal, which is the main reason for the breakdown of the needle jumping machine. In view of the above reasons, it is suggested that the following ways be adopted to solve these problems. Wrist curling machine Needle failure:

1. check whether the bending needle is synchronous with the machine needle (turning the machine. When the bending needle moves forward and backward, the pinhole should intersect with the pinhole of the machine). If it is not synchronized, the screw of the belt gear can be screwed down, and the upper gear and the lower gear can be synchronously adjusted at any time. At the same time, when we bend the needle to the far right, the distance from the tip of the needle to the center of the needle should be 2.6 mm to 2.8 mm. When the bending needle meets the machine needle, the gap between the bending needle and the needle should be 0.1 mm to 0.2 mm.

2. if the hook line is too small, we can adjust the hook thread on the machine and enlarge the hook line.

3. turn the machine. Curved needle When you meet, the needle tip should be 1.5 mm above the bottom of the guide pin, and the guide pin is just in contact with the machine needle. In addition, we need to check whether the needle is in the middle of the guide pin, and the needle is in contact with the guide pin.

4. we turn the machine clockwise. When the needle reaches the top dead center, the conductor wheel and the over board will be 45 degrees to 50 degrees.
