Technical Field
[0001] The utility model relates to the technical field of weft knitting equipment, in particular to a high-tension balance control device for a weft knitting machine. Background Art
[0002] A weft knitting machine is a textile machine that forms a fabric by interweaving weft yarns and warp yarns. During the knitting process, the tension control of the weft yarn is crucial, which directly affects the density, uniformity, elasticity, and appearance quality of the fabric. If the weft yarn tension is too large, it may cause the fabric to be too tight, deformed, or even broken; while if the tension is too small, problems such as slackness, wrinkling, or weft missing may occur.
[0003] However, the traditional tension balance device of a weft knitting machine is difficult to achieve automatic adjustment, and the adjustment process is relatively rigid, which is more likely to cause problems such as the weft yarn breaking or falling off due to excessive or too small tension and too rapid adjustment when the weft yarn tension is too large or too small.

Detailed implementation manner
[0021] An embodiment of the present utility model provides a high-tension balance control device for a weft knitting machine, as Figures 1-4 shown, including a balance bucket 11, a first limit block 12, a second limit block 13, a first opening 14, a screw 15, an internal thread 16, an external thread 17, a limit end 18, a current-limiting plate 20, a first sliding plate 21, a second sliding plate 22, a first cavity 23, a second cavity 24, a third cavity 25, a weft pulling block 26, a weft perforation 27, a second opening 30, a current-limiting groove 31, a first connecting block 32, a third sliding plate 33, a spring 34, and a limit baffle 35.
[0022] As Figures 1-4 shown, the first limit block 12 is fixedly sleeved at one end of the balance bucket 11, the second limit block 13 is slidably sleeved at the other end of the balance bucket 11, first openings 14 are provided on both the first limit block 12 and the second limit block 13, a screw 15 is threadedly connected in the first opening 14, a balance cavity is provided in the balance bucket 11, a current-limiting plate 20 is fixedly arranged in the balance cavity, a first sliding plate 21 and a second sliding plate 22 are respectively slidably arranged on both sides of the current-limiting plate 20 in the balance cavity, and a plurality of second openings 30 are provided on the current-limiting plate 20.
[0023] It should be noted that the second limit block 13 is fixedly connected to the side plates on both sides of the weft of the weft knitting machine, and usually two of the present utility models need to be arranged on both sides of a weft.
[0024] A first cavity 23 is enclosed between the first sliding plate 21 and the second sliding plate 22, a second cavity 24 is enclosed between the first sliding plate 21 and one end face of the balance cavity, a third cavity 25 is enclosed between the second sliding plate 22 and the balance cavity, a weft pulling block 26 is fixedly connected to one end face of the second sliding plate 22 away from the current-limiting plate 20, a weft perforation 27 is provided in the weft pulling block 26, the weft perforation 27 is used for passing through the weft, an inert gas is filled in the second cavity 24, and damping oil is filled in the first cavity 23.
[0025] One end of the current-limiting plate 20 close to the second sliding plate 22 is fixedly connected with a first connecting block 32. A current-limiting groove 31 is provided on the side of the second opening 30 far from the first connecting block 32. One end face of the first connecting block 32 far from the current-limiting plate 20 is fixedly connected with a limiting baffle 35. A number of springs 34 are fixedly connected to the limiting baffle 35. A third sliding plate 33 is sleeved on the outer circular surface of the first connecting block 32. The third sliding plate 33 is fixedly connected with the springs 34. The diameter of the second opening 30 gradually increases from the end close to the first sliding plate 21 to the end close to the second sliding plate 22.
[0026] It should be noted that when the third sliding plate 33 is in close contact with the current-limiting plate 20, the third sliding plate 33 blocks the second opening 30.
[0027] External threads 17 are provided on the outer circular surface of the screw rod 15. Internal threads 16 are provided in the first opening 14 of the second limiting block 13. The internal threads 16 are adapted to the external threads 17. One end of the external threads 17 close to the first limiting block 12 is fixedly connected with a limiting end head 18.
[0028] When the tension balance of the weft knitting machine is carried out in this solution, first, the weft yarn is inserted from one end of the weft yarn perforation 27 and passes out from the other end. By rotating the limiting end head 18, the limiting end head 18 drives the screw rod 15 to rotate. The screw rod 15 is threadedly connected with the first opening 14 of the second limiting block 13, so that the limiting end head 18 adjusts the distance between the first limiting block 12 and the second limiting block 13, that is, adjusts the relative position between the balance barrel 11 and the side plate of the weft knitting machine, and changes the initial tension and tightness of the weft yarn.
[0029] When the tension of the weft yarn is large, when the weft yarn pulls the weft yarn pulling block 26 through the weft yarn perforation 27, the weft yarn pulling block 26 pulls the second sliding plate 22 to slide away from the current-limiting plate 20. Then, the damping oil in the first cavity 23 enters the right side of the current-limiting plate 20 from the left side of the current-limiting plate 20 through the second opening 30 and the current-limiting groove 31, and the damping oil pushes the third sliding plate 33 to slide towards the limiting baffle 35. The third sliding plate 33 compresses the springs 34. Finally, since the volume of the first cavity 23 increases, the pressure of the damping oil in the first cavity 23 decreases, and the inert gas in the second cavity 24 pushes the first sliding plate 21 towards the current-limiting plate 20.
[0030] When the tension of the weft yarn is small, the pulling force generated by the weft yarn pulling block 26 on the damping oil in the first cavity 23 through the second sliding plate 22 decreases. Therefore, the volume of the damping oil becomes smaller, and the volume of the first cavity 23 decreases. At this time, the springs 34 press the third sliding plate 33 on the current-limiting plate 20, and the damping oil slowly enters the left side of the current-limiting plate 20 through the current-limiting groove 31, and the first sliding plate 21 slides to the left.
[0031] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
