What is included in the motion mechanism of a leather sewing machine?

In recent years, with the development of technology and the support of national policy, intelligent sewing machines are thick duty sewing machines, rapid rise, and a number of heavy duty sewing machines for leather that focus on innovation and quality have emerged. Leather sewing machines are also no longer just models, such as long arm sewing machine, thick thread computerized pattern machine, container bag sewing machine, shoe sewing machine, sofa sewing machine, etc., but among the modern quality of life in the important intelligent industrial sewing machine products.

The head of leather sewing machine is composed of stabbing cloth mechanism, picking thread mechanism, hooking thread mechanism, feeding mechanism and special devices. As the structure and shape of raw material products such as leather and canvas are more complicated than that of garments, etc., the body of Sails Sewing Machine for leather is of various shapes, mainly of hanging cylinder type, column type and box type. In order to adapt to the sewing of tents, sails, mattresses, bags and other large products, its body shape is also larger than the common industrial sewing machine.

(1) Thread-taking-up mechanism: leather products sewing machine prick cloth mechanism of the form and flat sewing machine is basically the same, is also a crank linkage, but the size of its machine parts is larger. The tip of the needle is not round but has a special shape. It pierces through the material in a cutting manner, which avoids damage to the leather and minimizes needle breakage. The cutting hole of the special shaped needle tip usually forms a certain angle with the seam, so that each stitch is drawn tightly and neatly.

(2) Thread picking mechanism: mostly cam wheel type thread picking mechanism, which can satisfy any regular movement of thread picking culm. In sewing leather, canvas and other thick products, needle thread in the needle piercing and exit the sewing material will be greater damage, the ideal requirement is: in the bobbin tip hooked needle thread thread ring, picking the culm can accordingly make a long pause, when the needle exit the sewing material picking the culm and then a large number of rapid loss of thread and draw the thread tightly. Cam-type picking mechanism than other types of picking mechanism to meet these requirements, the structure is also simple, but in the higher sewing speed sewing speed parts are easy to wear, the speed should not exceed 1500 stitches per minute.

(3) Hook thread mechanism: in the leather products sewing machine sewing thread than the ordinary sewing machine is much thicker, so usually use a large capacity of non-central bobbin shuttle. One of the long bobbin bobbin is a kind of leather products sewing machine used more. It is characterized by: when the pendulum shuttle tip into the needle thread thread ring, so that the thread ring to keep in the tip of the mouth does not make the expansion, until the needle out of the sewing material. Obviously, when the needle out of the sewing material after the pendulum shuttle and then expand the thread ring, the needle and thread in the sewing material through there is no obstacle to greatly reduce the damage to the sewing thread, which is more important for sewing thick or viscous sewing material.

(4) Feeding mechanism: there are various forms. General sewing machine with serrated feeding teeth can not effectively transfer high hardness of leather, in order to achieve better feeding effect and reduce the damage of leather surface, leather products sewing machine often use feeding roller instead of feeding teeth. In addition to roller feeding, there are up and down comprehensive feeding, up, down and needle comprehensive feeding and other forms, they can make the surface of the sewing material is not damaged and to overcome the multi-layer sewing, some models of leather products sewing machine is equipped with lubrication of the needle and thread of the immersion tank.

The above is the leather sewing machine each link of the movement mechanism, double star in the thick material machine manufacturing industry through thick and thin 30 years, know the user's needs, double star in the development of sewing machines in the road of innovation and change in the continuous upgrading of the sewing machine to do a good job in the manufacture of sewing machines, the customer demand is very important, but more importantly is the quality of the sewing machine.
