AI Technical Summary
Traditional high-head leather sewing machines lack an adjustment mechanism in their design of a fixed needle guard plate on the outer circle of the shuttle bed. This results in severe friction between the needle and other parts, affecting the quality of the sewing stitches and work efficiency, and increasing maintenance costs.
A threaded fine-tuning hole is machined on the outer circle of the moon ring, and the needle guard plate is connected by an internal hex screw to achieve precise adjustment of the position of the needle guard plate, thereby reducing friction and collision between the needle and the hook tip of the rotary hook.
It effectively protects the hook tip of the rotary hook, extends its service life, improves the production efficiency and sewing quality of the sewing machine, and reduces maintenance costs.

TECHNICAL FIELD
[0001] The utility model belongs to sewing machine technical field, concretely relates to a high head sewing machine shuttle. BACKGROUND
[0002] In the use process of the high head sewing machine for thick leather, the friction problem of the needle and the shuttle bed and other components is more common. Because the force is complex when sewing thick leather, the needle is prone to improper contact with the shuttle bed and other components in frequent puncture action, and then the shuttle hook tip is damaged. Once the shuttle hook tip is damaged, not only the quality of the sewing machine stitch is affected, but also problems such as thread breakage and needle skipping may occur, which seriously reduces the working efficiency of the sewing machine, increases the maintenance cost and downtime. The traditional high head sewing machine for thick leather lacks effective adjustment mechanism in the design of the needle guard plate fixed on the outer circle of the shuttle bed ring, and it is difficult to accurately control the position of the needle guard plate, so it is difficult to solve the friction problem of the needle and other components.
[0003] Therefore, the utility model designs a high head sewing machine shuttle. CONTENT OF THE UTILITY MODEL
[0004] The utility model aims at providing a high head sewing machine shuttle to solve the problems in the background art.
[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme: a high head sewing machine shuttle, comprising a shuttle bed body, a shuttle holder is rotationally arranged inside the shuttle bed body, a shuttle hook tip is fixedly installed on the outer side of the shuttle bed body, a ring is fixedly installed on the outer side of the shuttle bed body for guiding the sewing thread, and a needle guard plate is installed on the outer circle of the ring through a screw thread adjustment assembly.
[0006] Preferably, the inside of the shuttle holder is provided with an annular bobbin for storing sewing thread.
[0007] Preferably, a threaded hole corresponding to the fixing screw is formed in the top edge of the shuttle bed body, and the top surface of the ring is fixedly connected with the shuttle bed body through the fixing screw.
[0008] Preferably, the screw thread adjustment assembly comprises a screw thread fine adjustment hole formed on the outer circle of the ring, an outer connecting hole formed on the outer surface of the needle guard plate and corresponding to the screw thread fine adjustment hole, an internal hexagonal screw is arranged in the screw thread fine adjustment hole, and the needle guard plate is connected with the ring through the internal hexagonal screw.
[0009] Preferably, the opening of the screw thread fine adjustment hole is outwardly expanded, and the caliber of the screw thread fine adjustment hole is consistent with the caliber of the outer connecting hole.
[0010] Compared with the prior art, the utility model has the advantages of:
[0011] The position of the needle guard plate can be finely adjusted through rotating the internal hexagonal screw by precisely machining a threaded fine adjustment hole at a specific position of the outer circle of the moon ring; the correct size position of the needle guard plate can be more conveniently controlled and adjusted; the needle guard plate can protect the thread hooking tip of the rotating hook from being damaged; the friction and collision between the needle and the thread hooking tip of the rotating hook are reduced, so that the wear of the thread hooking tip of the rotating hook is greatly reduced, thereby indirectly and significantly prolonging the service life of the rotating hook; the quality and stability of the leather thick material sewing are improved, the maintenance cost of the equipment is reduced, and the production efficiency is improved.
