Detailed Description

For further understanding of the contents, features and effects of the present invention, the following embodiments are described in detail.

Referring to fig. 1 and 2, the pay-off device for a high-speed braiding machine of the present invention includes an i-shaped spindle base 3 with a sliding block 2 at the bottom, and a let block 1 is installed in the middle of the spindle base 3.

The block 1 is used for matching with notches arranged at the edges of rotating discs of the knitting machine equipment and is clamped by corresponding notches of two adjacent rotating discs (called as a first rotating disc and a second rotating disc), so that the conveying movement of the pay-off device is realized. The slide blocks 2 are matched with a slide way on a platform of a braiding machine to realize the guiding movement of the pay-off device, a first circular slide way and a second circular slide way are correspondingly arranged on the surface of a substrate of the braiding machine and below two rotating discs (a first rotating disc and a second rotating disc), the first slide way and the second slide way are communicated at the middle parts to form an 8-shaped complete slide way, and each slide block 2 is positioned in the slide way.

As can be seen from the figure, two sliding blocks 2 below the spindle seat 3 are arranged, are both flat and can be made of metal plates. Can set up two shaft holes in the bottom of spindle bearing 3, set up the round pin axle in the pinhole, fix slider 2 installation on two round pin axles, two sliders 2 can use respective round pin axle to rotate as the center like this, when slider 2 removes in the complete slide of above-mentioned "8" font like this, can adapt to the change of slide inner arc degree better.

Therefore, when the three pay-off devices move along the through 8-shaped slide way under the driving action of the first turntable and the second turntable of the knitting machine, the slide block 2 can enter the other slide way from one slide way when moving at the through position between the first slide way and the second slide way (correspondingly, the let block 1 of the pay-off device is transferred from the notch of the previous turntable to the notch of the next turntable), so that each pay-off device also moves on the 8-shaped path, and the three pay-off devices jointly form the knitting action of the twist plait.

A base 4 is attached to the spindle base 3 (fixed by a fixing screw), a bobbin base 5 having a bobbin center shaft 12 is attached to the base 4, and a yarn bobbin 14 is mounted on the bobbin center shaft 12. Specifically, since the base 4 is provided with a rotating shaft and a bearing is mounted between the rotating shaft and the bobbin holder 5, the assembly of the bobbin center shaft 12 (and the bobbin 14) and the bobbin holder 5 can freely and flexibly rotate on the base 4.

Referring to fig. 3 and 4, the base 4 is further provided with a fixing support 6 and a lifting support 11 with a gland 13 at the top, a telescopic mechanism is arranged between the bottom of the lifting support 11 and the top of the fixing support 6, a plurality of threading holes 10 are arranged in the middle of the lifting support 11, thread protecting sleeves 9 are arranged in the threading holes 10, the braided wire unreeled from the yarn tube 14 passes through the thread protecting sleeves 9, and the thread protecting sleeves 9 enable the braided wire to pass more smoothly.

In this embodiment, a mounting groove is formed in the outer side of the base 4, a pressing block 4-1 with a T-shaped cross section is mounted in the mounting groove by bolts, a left end leg and a right end leg are arranged at the lower end of the fixing bracket 6, and the two end legs are pressed and fixed in the mounting groove by the pressing block 4-1, so that the fixing bracket 6 (together with the lifting bracket 11) can be conveniently detached from the base 4.

The bracket assembly consisting of the fixing bracket 6 and the lifting bracket 11 is used to fix the yarn tube 14 to the tube central shaft 12 while providing sufficient lateral protection. Specifically, when the yarn package 14 runs out and needs to be replaced, the lifting bracket 11 is lifted to a certain height, the upper end of the bobbin central shaft 12 is released, and the yarn package 14 can be lifted upwards and detached, and then other full yarn packages 14 are replaced.

In this embodiment, the gland 13 is hinged to the top of the lifting support 11, a lock hole is formed in the middle of the gland 13, a lock tongue is arranged at the upper end of the bobbin center shaft 12, and the lock tongue is inserted into the lock hole and locked by a lock piece. In this embodiment, the locking member may be a snap spring, when the pressing cover 13 is downwardly fastened to the latch tongue at the upper end of the bobbin center shaft 12, the snap spring fixes the pressing cover 13 to the upper end of the bobbin center shaft 12, and when the fixing needs to be released to disassemble and assemble the bobbin tube 14, the snap spring is pressed to deform to release the fixing.

In this embodiment, telescopic machanism includes telescopic link 7 and the cover establishes the spring 8 at telescopic link 7 outside, and the upper end of telescopic link 7 and the lower extreme fixed connection of lifting support 11 are equipped with the guide hole at the top of fixed bolster 6, and the lower extreme of telescopic link 7 is located the guide hole, and when lifting support 6 did the lift removal, telescopic link 7 and guide hole cooperation realized the function of stable direction, and spring 8 provides certain elasticity, makes and keeps the tensioning between fixed bolster 6 and the lifting support 11.

In this embodiment, referring to fig. 1 and 3, a protection wing plate 6-1 is further provided on the inner side of the lower end of the fixing bracket 6, the protection wing plate 6-1 is located on the outer side of the bobbin seat 5, and the protection wing plate 6-1 isolates the rotating bobbin seat 5 (and the lower end edge of the yarn tube 14) from the main body of the fixing bracket 6.

The using method comprises the following steps:

referring to fig. 4, it can be seen that: pressing down the snap spring, opening the gland 13 upwards, loading the bobbin 14 full of yarn downwards onto the bobbin central shaft 12, and then buckling the gland 13 until the snap spring connects the gland 13 with the upper end of the bobbin central shaft 12 into a whole; the end of the braided wire unreeled from the yarn bobbin 14 is pulled to pass through the thread protecting bush 9 in one of the threading holes 10, and the end of the braided wire is pulled continuously to reach the braiding device of the braiding machine for braiding.
