AI Technical Summary
In existing sock machines, the needle tongue is prone to closing during high-speed rotation, leading to needle leakage and failure to effectively catch yarn.
Design an upper steel ring structure with a protrusion and a V-shaped groove on the inner side to guide the yarn into the sock needle tongue, ensuring that the sock needle tongue always remains open. The cooperation of the protrusion and the V-shaped groove controls the yarn to enter the sock needle and prevents it from closing.
It effectively prevents abnormal closure of the sock needle tongue, ensuring that the yarn can be hooked deeply, avoiding missed needle failures, and improving knitting efficiency and precision.

Description
TECHNICAL FIELD
[0001] The utility model belongs to hosiery equipment technical field, especially relate to a hosiery with yarn guide enters the hosiery with the upper steel ring of needle tongue. BACKGROUND
[0002] The upper steel ring is an important core component for installing the shuttle and cooperating with the knitting needle on the needle cylinder of the hosiery, and the current hosiery needs to ensure that the needle tongue is in the open state when knitting socks. However, the needle tongue of the high-speed rotating hosiery may be closed due to various reasons, which leads to the failure of hooking the yarn and causes the missing needle problem. How to prevent the needle tongue of the hosiery from being closed abnormally is the object of research for those skilled in the art. CONTENT OF THE UTILITY MODEL
[0003] The utility model provides a hosiery with yarn guide enters the hosiery with the upper steel ring of needle tongue, which has the advantages of simple structure, less needle tongue closing failure, accurate control, and high precision.
[0004] A hosiery with yarn guide enters the hosiery with the upper steel ring of needle tongue, which has the advantages of simple structure, less needle tongue closing failure, accurate control, and high precision.
[0005] The V-shaped groove includes an inclined first groove wall and a second groove wall, the bottom of the first groove wall and the second groove wall is connected by a horizontal plane, the horizontal plane is provided with a bevel edge integrated with the protrusion in the horizontal direction, the bevel edge cooperates with the knitting line in the needle tongue, and the needle tongue is opened by the driving of the sock cylinder. The first circular surface cooperates with the bevel edge and the horizontal plane to form an open tongue triangle to open the needle tongue.
[0006] The protrusion includes a first circular surface, a horizontal guide surface, and a second circular surface, the first circular surface cooperates with the forward rotation of the hosiery needle, the second circular surface cooperates with the reverse rotation of the hosiery needle, and the second circular surface also ensures that the needle tongue is in the open state under the driving of the sock cylinder. The second circular surface cooperates with the hosiery needle to keep the needle tongue open.
[0007] The V-shaped groove cooperates with the overline shuttle, and the overline shuttle is installed on the mounting seat of the upper ring.
[0008] The convex block on the inner side of the inner ring is arranged to guide the yarn into the latch of the needle, the convex block cooperates with the V-shaped groove of the ring wall of the inner ring, the V-shaped groove passes through the yarn, and the yarn is more deeply guided into the needle under the cooperation of the convex block, so that the problem of needle missing caused by shallow yarn feeding of the needle is avoided. BRIEF DESCRIPTION OF DRAWINGS
[0009] The utility model makes further explanation in connection with the drawings:
[0010] Figure 1 It is the upper ring three-dimensional structure schematic diagram for hosiery with yarn guiding into the latch of the needle;
[0011] Figure 2 It is Figure 1 The enlarged structure schematic diagram of A in the middle;
[0012] Figure 3 It is the structure schematic diagram of the upper ring in use state in the utility model. DETAILED DESCRIPTION
[0013] The utility model makes further explanation in connection with the drawings: Figures 1-3 The technical scheme of the patent is explained in further detail in the specific implementation manner.
[0014] An upper ring for hosiery with yarn guiding into the latch of the needle, comprising an upper ring 1, the upper ring 1 includes annular ring body, the inner side of the ring body is provided with coaxial inner ring 4 that reduces, the inner ring 4 is connected between the ring body by reinforcing rib 3, the inner side of the inner ring is provided with the convex block 9 that guides the latch of the needle to always be in open state towards the hosiery needle, the convex block 9 cooperates with the V-shaped groove of the ring wall of the inner ring, and it is ensured that the latch of the needle is always in open state by the convex block 9.V-shaped groove cooperates with overline shuttle 14, and the overline shuttle 14 is installed on the mounting seat 2 of the upper ring 1.
[0015] As the structure is preferred, the V-shaped groove includes inclined first groove wall 12 and second groove wall 10, the bottom of the first groove wall 12 and the second groove wall 10 is connected by horizontal plane 11, and the horizontal plane 11 is provided with inclined edge 7 integrated with the convex block 9 in the horizontal direction.The first circular surface 6 cooperates with the inclined edge 7 and the horizontal plane 11 to form open-latch triangle to open the latch of the needle, and it is ensured that the latch of the needle can be opened in the process of each positive and negative rotation when knitting the heel of the sock.The inclined edge 7 further guides the yarn to be more deeply guided into the needle.
[0016] As a structure preferred bump 9 includes integrally formed first circular arc surface 6, horizontal guide surface 18, second circular arc surface 8, the first circular arc surface 6 matches the positive rotation of the hosiery machine needle 13, the second circular arc surface 8 matches the reverse rotation of the hosiery machine needle 13. The second circular arc surface 8 matches the hosiery machine needle 13 to close the needle tongue, and ensures that the hosiery machine needle 13 can be in an open state during each positive and reverse rotation process when knitting the hosiery heel.
