DETAILED DESCRIPTION

[0024] The utility model will be explained in further detail below in combination with the drawings and specific embodiments.

[0025] As Figures 1-6 shown, a radial braiding mechanism of a circular knitting machine, comprising a braiding ring 1, the movable block 2 is movably installed along the circumference of the braiding ring 1, the movable block 2 is arranged in a central symmetry relative to the braiding ring 1, and the number thereof can be adjusted according to the knitting needs. The limiting hook 3 is installed on the movable block 2 to guide the looping of yarn, and the swing driving assembly 4 and the unhooking driving assembly 5 are arranged between the movable block 2 and the braiding ring 1. When the braiding ring 1 rotates as a whole or the external guide wire structure rotates circumferentially, the swing driving assembly 4 and the unhooking driving assembly 5 are linked to continuously pull and push the wire.

[0026] Specifically, unlike the conventional ring body structure of a circular knitting machine, the braiding ring 1 in the embodiment has a movable groove 11 that is circumferentially encircling and open at the upper end for installing the movable block 2, the movable block 2 has a movable protrusion 12 that is slidingly connected with the movable groove 11, and a clamping assembly is arranged between the movable block 2 and the movable groove 11. The clamping assembly applies a top pressure moment to the movable groove 11, so that the axial and circumferential positions of the movable block 2 are fixed, avoiding dislocation caused by pulling.

[0027] In depth, the clamping assembly is assembled in a manual manner, specifically including a clamping screw 13 rotatably mounted on the movable block 2, the clamping screw 13 is driven by a reversing gear set to have a clamping push rod 14, the central axis of the clamping push rod 14 extends radially along the braided ring 1, and a clamping block 15 is arranged at the end of the clamping push rod 14 to abut and press the inner side of the movable groove 11. The rotation of the clamping screw 13 causes the clamping push rod 14 to slide radially, and the clamping block 15 applies a pressing torque to the inner side of the movable groove 11. The clamping push rod 14 is usually arranged in pairs and the sliding directions are opposite.

[0028] Further, the limiting hook 3 made of stainless steel is slidably mounted in the movable block 2, the limiting hook 3 is provided with a limiting groove 31 extending in the vertical direction, and the movable block 2 is fixedly provided with a limiting shaft 32 in sliding connection with the limiting groove 31. When the limiting hook 3 is moved, the limiting shaft 32 prevents the limiting hook 3 from being separated from the movable block 2, and the limiting shaft 32 does not affect the normal swinging.

[0029] Further, in order to obtain the maximum activity interval, the swinging driving assembly 4 includes a swinging groove 41 arranged at the upper end of the limiting groove 31, the swinging groove 41 is triangular, an elastic return member is arranged between the limiting hook 3 and the swinging groove 41, an electromagnet 42 is arranged at the lower end of the limiting hook 3, and the telescopic end of the electromagnet 42 is movably connected with the lower end of the limiting hook 3. When the movable block 2 is opposite to the external loop structure, the electromagnet 42 is inductively started or stopped to move the limiting hook 3 upward, the elastic return member applies an elastic force to make it deviate, and the hook body of the limiting hook 3 is hooked with the yarn. When the movable block 2 is separated from the external loop structure, the limiting hook 3 is reset as a whole and pulls the yarn downward.

[0030] In addition, the unhooking driving assembly 5 adopts a swinging push line mode, specifically including a push yarn rod 51 rotatably connected with the movable block 2, the push yarn rod 51 is drivingly connected with a linkage rod 52 extending to the outside of the movable block 2 through a reversing gear set, and an elastic return member is arranged between the push yarn rod 51 or the linkage rod 52 and the movable block 2. When the movable block 2 moves to a specified position, the linkage rod 52 receives a pushing force from the external linkage structure, drives the push yarn rod 51 to swing through the reversing gear set, and then pushes the yarn pulled by the limiting hook 3 out of the hook body.

[0031] At the same time, the limiting hook 3 is flat and long strip-shaped as a whole and the surface is chrome-plated, the corners of the limiting hook 3 are rounded to avoid damaging the yarn, and the relative friction of the yarn is reduced when the yarn moves.

[0032] As can be seen, in order to facilitate the overall assembly of the circular knitting machine, a plurality of adapter seat bodies 6 are arranged at the lower end of the braided ring 1 in a central symmetric manner, a plurality of adapter holes 61 are arranged on the adapter seat bodies 6, and the adapter holes 61 are positionally fixed by threaded members. The adapter seat bodies 6 extend to the inside of the braided ring 1.

[0033] It is obvious that the upper and lower ends of the braided ring 1 are respectively provided with light sensors, and the braided ring 1 is provided with a contact sensor between the movable block 2 and the limiting hook 3. The light sensor and the contact sensor are connected with the main control unit,

[0034] Preferably, the braided ring 1 is provided with a support ring 7 outside, and the support ring 7 is fixedly connected with the braided ring 1. The support ring 7 supports and stabilizes the structure of the braided ring 1, and facilitates the switching of the external limiting structure, and can be switched on the support ring 7 as needed.

[0035] In summary, the principle of the embodiment is that the movable block 2 is installed on the braided ring 1, and the limiting hook 3 on the movable block 2 is lifted and swung under the linkage action of the swing driving assembly 4 and the hook withdrawing driving assembly 5, realizing continuous pulling and disengagement of the yarn, and cooperating with the external loop forming mechanism to ensure the continuity of the yarn disengagement.

[0036] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, without deviating from the spirit of the present application or exceeding the scope defined by the appended claims.

[0037] Although the terms such as braided ring 1, movable groove 11, movable protrusion 12, clamping screw 13, clamping push rod 14, clamping block 15, movable block 2, limiting hook 3, limiting groove 31, limiting shaft 32, swing driving assembly 4, swing groove 41, electromagnet 42, hook withdrawing driving assembly 5, yarn pushing rod 51, linkage rod 52, adapter seat 6, adapter hole 61, support ring 7 are used more frequently herein, but the possibility of using other terms is not excluded.
