Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a vertical rod group structure used for special textile equipment. Background Art

[0002] Textile machines are the various mechanical devices required to process natural or chemical fibers into textiles. On a loom, the warp yarns are drawn from the warp beam, their upward and downward movement controlled by devices such as droppers and heald frames. The weft yarns are introduced into the weft shed by the weft insertion mechanism and interwoven with the warp yarns. The beating-up mechanism pushes the weft yarns toward the weft shed, tightly interweaving the warp and weft yarns to form the fabric. The warp let-off mechanism continuously delivers the warp yarns to ensure continuous weaving.

[0003] The heald frames of existing textile machines are driven by cams. In high-speed cam transmission systems, the wear of the cams and followers will gradually increase over time, thereby affecting the rise and fall of the warp yarns. In addition, due to the rapid wear, the cams and followers need to be inspected and replaced regularly, which increases maintenance costs and downtime, affecting production progress.

Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0024] Please refer to Figures 1-4 , a vertical rod group structure for a textile special equipment, including a frame 5, two parallel harness frames 1 are arranged on the frame 5, the harness frame 1 is connected to a driving assembly 2, the driving assembly 2 includes a rotating shaft 21 rotatably arranged at both ends on the frame 5, two bumps 24 are respectively and fixedly arranged on the rotating shaft 21, the two bumps 24 are arranged corresponding to the harness frame 1 one by one, grooves 22 are formed on the bump 24 and the rotating shaft 21, a connecting rod 23 is rotatably connected to the end of the bump 24, the connecting rod 23 is rotatably connected to the harness frame 1, and one end of the rotating shaft 21 passes through the frame 5 and is fixedly connected to the output shaft of the motor; a guide rod 3 is also fixedly arranged on the harness frame 1, and the guide rod 3 is slidably connected to the frame 5. The motor is fixedly arranged on the frame 5.

[0025] By providing the driving assembly 2, the motor drives the rotating shaft 21 to rotate, the rotation of the rotating shaft 21 drives the bump 24 to rotate, the rotation of the bump 24 drives the corresponding connecting rod 23 to rotate, the rotation of the connecting rod 23 drives the corresponding harness frame 1 to move, and makes the movement directions of the two harness frames 1 opposite, so that the harness frame 1 can drive the warp yarns to move up and down, so as to cooperate with the weft yarns for weaving. The structure of the present utility model is simple, and the wear degree is greatly reduced compared with that of a cam, reducing the maintenance frequency.

[0026] Further, the protruding directions of the two bumps 24 are both perpendicular to the rotating shaft 21 and are in the same plane. Thus, the movement directions of the two harness frames 1 are always opposite to realize the lifting of the warp yarns.

[0027] Further, a plurality of vertical rods 11 are also arranged on the harness frame 1, harness eyes 12 are formed in the middle of each vertical rod 11, and a wire passing channel is formed between adjacent vertical rods 11. The vertical rods 11 and the wire passing channels on the two harness frames 1 are arranged corresponding to each other, so that adjacent warp yarns respectively pass through the harness eyes 12 on the two harness frames 1, thereby completing the lifting of adjacent warp yarns.

[0028] Further, an adjusting plate 4 is slidably connected within the heddle frame 1. One end of the vertical rod 11 is fixedly provided with a positioning rod 41. The positioning rod 41 extends into an adjusting groove 42 on the adjusting plate 4. The other end of the vertical rod 11 is slidably connected to the heddle frame 1. A locking portion is further provided on the heddle frame 1.

[0029] The adjusting plate 4 is used to adjust the distance between the vertical rods 11 to adapt to different weaving requirements. Specifically, by rotating the locking rod 43, the locking rod 43 drives the adjusting plate 4 to move. The movement of the adjusting plate 4, through the cooperation of the adjusting groove 42 and the positioning rod 41, causes the vertical rod 11 to move, thereby changing the distance between the vertical rods 11. When the number of vertical rods 11 is even, its symmetric position should be on the central plane of the heddle frame 1. When the number of vertical rods 11 is odd, its symmetric position should be on the central plane of the middle vertical rod 11, and the adjusting groove 42 corresponding to the positioning rod 41 on this vertical rod 11 is a vertical groove, that is, the middle vertical rod 11 remains stationary.

[0030] Working principle: The motor drives the rotating shaft 21 to rotate. The rotation of the rotating shaft 21 drives the cam 24 to rotate. The rotation of the cam 24 drives the corresponding connecting rod 23 to rotate. The rotation of the connecting rod 23 drives the corresponding heddle frame 1 to move, and makes the movement directions of the two heddle frames 1 opposite, so that the heddle frame 1 can drive the warp yarns to move up and down, facilitating the cooperation with the weft yarns for weaving. And the distance between the vertical rods 11 can be changed by the adjusting plate 4 to adapt to different weaving requirements.

Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
