Long Arm Sewing Machine Innovations & Common Sense Identification of Parts & Accessories

Long arm sewing machine innovation design is carried out on three levels, the innovation of the sewing working principle, the innovation of the sewing process, the innovation of the actuator and combination. the machine overall equipment of high quality, innovative design can reflect the sewing of the various performance of mining.

The working principle of sewing machine is as follows: chain stitch, chain stitch, overlock stitch, taut stitch, prying stitch, glued sewing and so on. The innovation of the working principle will produce a new class of sewing machines, resulting in a high level of innovation.

Realize the same sewing principle can be used with different sewing technology action process. The new technology action process will get a new product. The innovation of the process is at a lower level of innovation.

Adopting new actuators and new combinations of actuators can also make the sewing machine innovative.

Sewing machine parts are the core of the whole machine, and its spare parts should not be neglected. For example, needle plate and feed teeth, presser foot, needle and rotary hook, etc. Each part has its place. The quality of each part can not be ignored.

(1) Needle plate and feed teeth

The needle plate and cloth feed teeth of medium-speed machines are double-rowed, and the latter part is subjected to greater force, so it is easy for the operator to hit the needle when using a long arm sewing machine with a reverse feed wrench for reverse feed operation. If there is a needle phenomenon, the needle plate will be collapsed, such as the use of good quality needle plate is not easy to appear such a phenomenon.

Inspection method: use the compass knife into the needle plate on the cloth feed teeth groove, and shaking left and right, carefully observe whether the deformation of force, such as deformation that is poor quality products.

(2) pressure foot

Inspection method: the pliers can be used to bite the presser foot to see if it can be bitten out of the mark. Quenched harder pressure foot, pliers are not bite marks.

(3) Needle selection of high when the high-speed double-section, silver-white, nickel-plated needle. Because most of the sewing products enterprise is a high-speed machine, there are many sewing products are new waterproof materials and chemical synthetic fiber materials, thus requiring the needle must be high temperature, general chrome-plated needles are not adapted, even if available, the effect is not ideal. Imported machine needles of good quality, smooth surface, the use of time (4) rotary hook is also the same choice of imported rotary hook, rotary hook skin in the middle of the "q" imprint, print the bump fine, smooth and soft plating, feel smooth and hairless, rotary hook shell inside the hole on the left side of the print for the "N", the right side of the print for the "T". The Hirose rotary hook tip is not easy to burr when using. Fake rotary hook has shaking phenomenon in the bobbin case, the plating surface is brighter, there is a burr in the hand, the print of "q" on the bobbin skin is rough, the hardness of the bobbin tip is not enough, and it is easy to have a burr and a blunt tip phenomenon in the use of the bobbin.

Long arm sewing machine - Topeagle for the user to provide long arm machine performance guidance, the development and emergence of CNC machine tool technology for the production and operation of the machinery manufacturing industry has brought about a breakthrough change.
