Embodiment 1

[0037] Such as figure 1 As shown, the present embodiment provides a cylindrical bearing yarn carrier, which includes a shaft sleeve 1 and a movement assembly arranged in the shaft sleeve 1 and rotatingly matched with the shaft sleeve 1, and a hook 2 for connecting the yarn is installed on the movement assembly.

[0038]Due to the rotational cooperation between the moving assembly and the shaft sleeve 1, during the movement of the cylindrical bearing yarn carrier 10, the rolling friction between the adjacent cylindrical bearing yarn carriers 10 is formed between the shaft sleeve 1 and the shaft sleeve 1, and the shaft sleeve 1 Compared with the point contact between the ball and the ball, this design structure reduces the friction resistance between the cylindrical bearing yarn carrier 10 and also ensures the wear resistance between the two effect, thereby ensuring the working accuracy of the cylindrical bearing yarn carrier 10, during the working process, the error of the driv...

Embodiment 2

[0040] This embodiment is optimized and defined on the basis of the above-mentioned embodiment 1.

[0041] Such as figure 1 As shown, the moving assembly includes a mandrel 3 fixedly connected to the lower end of the hook 2 and a bearing 4 arranged on the mandrel 3 , the bearing 4 is arranged in the shaft sleeve 1 , and the outer ring of the bearing 4 drives the shaft sleeve 1 to rotate.

[0042] Specifically, the upper end of the shaft sleeve 1 , the upper end of the bearing 4 and the upper end surface of the mandrel 3 are all flush.

[0043] Bearing 4 uses standard parts, which reduces machining errors and is easy to replace. The cylindrical bearing yarn carrier 10 can rotate at high speed, runs evenly, is wear-resistant, and runs fast. The smooth rotation of sleeve 1, the rotation can reduce the friction with the row track.

[0044] Specifically, the hook 2 is fixedly connected to the middle part of the upper end of the mandrel 3, and when the mandrel 3 keeps the axis cen...

Embodiment 3

[0046] The present invention also provides a three-dimensional knitting machine using a cylindrical bearing yarn carrier 10, such as image 3 As shown, it includes a guide rail 7, a square chassis 6 for installing the guide rail 7, and a driving device for driving the guide rail 7 to move in rows and driving the cylindrical bearing yarn carrier 10 to move in columns. The two ends of the guide rail 7 in the length direction are provided with pushers Rod 9, the driving device drives the guide rail 7 through the push rod 9; when the three-dimensional braided piece is processed by the four-step process, the guide rail 7 and the cylindrical bearing yarn carrier 10 are driven by the driving mechanism 7, so that the cylindrical bearing yarn carrier 10 is in the direction of travel. Alternate reciprocating motion with a step length in the column direction.

[0047] N guide rails 7 are arranged sequentially along the width direction of the guide rails 7 and placed in the square chassis...

Abstract

The invention relates to the technical field of three-dimensional knitting, and discloses a cylindrical bearing yarn carrier and a three-dimensional knitting machine adopting the same. The yarn carrier comprises a shaft sleeve and a motion assembly arranged inside the shaft sleeve in rotating fit with the shaft sleeve, and a hook for being connected with yarn is installed on the motion assembly. By improving the structure of the yarn carrier, the yarn carrier is not likely to be abraded, effective working of the three-dimensional knitting machine is ensured, and the yarn carrier is reasonablein structural design and high in working stability.

Description

technical field [0001] The invention relates to the technical field of three-dimensional knitting, in particular to a cylindrical bearing yarn carrier and a three-dimensional knitting machine using the yarn carrier. Background technique [0002] During the operation of the existing three-dimensional knitting machine, since the processing dimension accuracy of the yarn carrier cannot fully meet the design size, the yarn carrier may not move in place, and as the movement proceeds, it will lead to an error in the driving position of the yarn carrier Accumulation, so there will be "stuck" phenomenon; and the noise and vibration are loud during operation; this not only increases the labor intensity and danger of workers, but also suspends production to check and maintain the machine, which is undoubtedly time-consuming and laborious , seriously affecting the efficiency of production. On the other hand, at present, there is hard contact and sliding friction between the yarn carri...
