Description

Technical Field

[0001] The utility model relates to the technical field of shuttles for circular knitting machines, in particular to a shuttle for a plastic circular knitting machine. Background Technique

[0002] During the normal knitting process of a plastic circular knitting machine, the weft yarn is loaded on the shuttle and moves in a circular motion with the shuttle. At the same time, the weft yarn is continuously drawn out and enters the fabric, and the shuttle itself makes a rotational motion. The shuttle tube of the traditional plastic circular knitting machine is positioned on the plastic circular knitting machine by a supporting taper sleeve relying on a compression spring. During operation, it is absolutely not allowed for the weft yarn tube to fall off the shuttle due to a fault. The traditional method to solve the above deficiencies is to increase the elastic force of the compression spring, but this is not a fundamental method because the elastic force of the compression spring becomes smaller with the service time, and it cannot fundamentally prevent the weft yarn tube from falling off the shuttle due to a fault. There are already patent documents that have made improvements to this.

[0003] In Chinese Patent CN202090131U, it relates to a shuttle for a plastic circular knitting machine, including a shuttle board, a weft yarn tube fixing seat, a supporting taper sleeve and a compression spring. The weft yarn tube fixing seats are symmetrically arranged on the shuttle board; the supporting taper sleeve is positioned on the weft yarn tube fixing seat through the compression spring; an arched stopper is rotatably arranged on the weft yarn tube fixing seat; a positioning hole is opened at one end of the arched stopper without a rotating shaft; when the arched stopper rotates to 180° with the horizontal position, it is placed in the gap between the weft yarn tube fixing seat and the supporting taper sleeve and fixed to the weft yarn tube fixing seat by bolts. The shuttle for the plastic circular knitting machine of the utility model is provided with an arched stopper that can effectively prevent the weft yarn tube from falling out of the supporting taper sleeve. The utility model is simple to manufacture and convenient to operate, and is widely used in plastic circular knitting machines.

[0004] Although the above patent can block the supporting taper sleeve through the arched stopper to prevent the weft yarn tube from falling out of the supporting taper sleeve, during the use of the shuttle, the spring will be compressed and reset for a long time, resulting in elastic fatigue of the spring, causing the spring to be unable to continue to provide support force. The spring not only lacks elasticity but also undergoes longitudinal sagging, causing the supporting taper sleeve to tilt, easily resulting in the weft yarn tube falling out of the supporting taper sleeve, affecting the normal operation of the shuttle. And since the weft yarn tube is installed between two supporting taper sleeves, due to the pressure of the spring, it requires the operator to forcefully squeeze through the weft yarn tube for installation, which is time-consuming and laborious. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a shuttle for a plastic circular knitting machine, which solves the problems that the spring will be compressed and reset for a long time, resulting in elastic fatigue of the spring, causing the spring to be unable to continue to provide support force, the spring not only lacks elasticity but also undergoes longitudinal sagging, causing the supporting taper sleeve to tilt, easily resulting in the weft yarn tube falling out of the supporting taper sleeve, and the need for the operator to forcefully squeeze through the weft yarn tube for installation, which is time-consuming and laborious.

[0006] To achieve the above object, the present utility model is realized by the following technical solutions: A shuttle for a plastic circular loom, comprising a shuttle board and weft yarn tube fixing seats fixedly connected to both sides of the top of the shuttle board. A groove is provided on one side of the weft yarn tube fixing seat. A sliding plate is slidably connected inside the groove. One side of the sliding plate is slidably connected with a support cylinder through an opening. A support rod is slidably connected inside the support cylinder. One end of the support rod is fixedly connected with a support cone sleeve. A first spring is sleeved on the outer surfaces of the support cylinder and the support rod and located between the sliding plate and the support cone sleeve. A limiting groove is provided on the top of the weft yarn tube fixing seat. A limiting rod is slidably connected to the bottom of the inner cavity of the limiting groove through an opening. One end of the limiting rod penetrates through the support cylinder and extends into the inside of the support cylinder. The other end of the limiting rod is fixedly connected with a circular plate. A second spring is sleeved on the outer surface of the limiting rod and located between the bottom of the inner cavity of the limiting groove and the bottom of the circular plate. A limiting hole adapted to the limiting rod is provided above the support cylinder.

[0007] Preferably, a connecting plate is fixedly connected above the surface of the support cone sleeve. A rotating iron bar is rotatably connected to the top of the connecting plate through an opening.

[0022] Please refer to Figures 1-5, the utility model provides a technical solution: a plastic circular loom shuttle, including a shuttle board 1 and weft yarn tube fixing seats 2 fixedly connected to both sides of the top of the shuttle board 1. A groove 3 is opened on one side of the weft yarn tube fixing seat 2. A sliding plate 4 is slidably connected inside the groove 3. One side of the sliding plate 4 is slidably connected with a support cylinder 5 through an opening. A support rod 6 is slidably connected inside the support cylinder 5. One end of the support rod 6 is fixedly connected with a support cone sleeve 7. A first spring 8 is sleeved on the outer surfaces of the support cylinder 5 and the support rod 6 and located between the sliding plate 4 and the support cone sleeve 7. A limit groove 9 is opened on the top of the weft yarn tube fixing seat 2. The bottom of the inner cavity of the limit groove 9 is slidably connected with a limit rod 10 through an opening. One end of the limit rod 10 penetrates through the support cylinder 5 and extends into the support cylinder 5. The other end of the limit rod 10 is fixedly connected with a circular plate 14. A second spring 11 is sleeved on the outer surface of the limit rod 10 and located between the bottom of the inner cavity of the limit groove 9 and the bottom of the circular plate 14. A limit hole 17 adapted to the limit rod 10 is opened above the support cylinder 5.

[0023] Further, in order to facilitate the installation of the weft yarn tube, a connecting plate 12 is fixedly connected above the surface of the support cone sleeve 7. The top of the connecting plate 12 is rotatably connected with a rotating iron bar 13 through an opening. A magnet clamping block 15 is fixedly connected to the top of the circular plate 14. A clamping groove 16 adapted to the magnet clamping block 15 is opened at the top of the rotating iron bar 13, and a plurality of clamping grooves 16 are provided.

[0024] Further, in order to facilitate pulling the rotating iron bar 13, a pulling plate 18 is fixedly connected to one side of the top of the rotating iron bar 13.

[0025] During use, when replacing the shuttle tube, by pulling the two rotating iron bars 13 to both sides respectively, the rotating iron bar 13 drives the support cone sleeve 7 to move to both sides through the connecting plate 12, and the clamping groove 16 on the rotating iron bar 13 is clamped on the magnet clamping block 15. The support cone sleeve 7 is limited and fixed by the rotating iron bar 13.
