[0002] The main function of the return needle triangle is to cooperate with the upper guard to determine the height of the return position of the long needle, and when weaving special patterns such as drum waves and partial weaving, the height of its position can be adjusted to achieve the purpose of smooth weaving. At present, most of the existing reset triangles are set on the front end surface of the return needle triangle, such as the computer flat knitting machine return needle triangle with the Chinese utility model patent publication number CN103710839A. This setting method causes the long needle to move along the track of the groove of the push needle block during the needle movement process, which not only makes the needle movement resistance large, but also easily causes the situation of needle cross-stitching, thereby affecting the reset of the long needle and the weaving effect, and the connection between the return needle triangle and the adjustment end of the push needle block is very thin, which is easy to break after long-term work, causing damage to parts and components, thereby causing economic losses to users.

[0003] In addition, the middle return needle cam in the prior art cannot adjust the reset position and height of the knitting needle according to the requirements of the cloth piece, and the return needle cam can only be designed according to the general cloth piece. Once the cloth piece is changed, the best effect cannot be achieved. Utility Model Content

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0026] Reference Figure 1 As shown, a high-strength adjustable return needle mechanism includes a first reset triangle 1 and a second reset triangle 2. The first reset triangle 1 is a pair and is respectively arranged on both sides of the mountain plate 3, and the second reset triangle 2 is arranged in the middle of the mountain plate 3. In this embodiment, a weaving unit is arranged between the second reset triangle 2 and the first reset triangle 1. This structure is an existing technology and will not be repeated here.

[0027] Combination Figure 3 As shown, specifically, the top surface of the first reset triangle 1 is provided with a horizontal needle running surface 11 which slides with the butt of the long needle, so that the butt of the long needle moves along the top surface of the first reset triangle 1, so that the knitting needle runs in a straight line, ensuring that the knitting needle runs more smoothly and is less likely to cause needle slippage.

[0028] Reference Figure 4 , Figure 5 As shown, further, a first return needle triangle 4 is slidably arranged on the rear side of the first reset triangle 1, and the first return needle triangle 4 includes an adjusting portion 41 and a needle pushing portion 42. The adjusting portion 41 and the needle pushing portion 42 are in an inverted "V" shape, and a V-shaped slide groove 12 matching the shape of the adjusting portion 41 and the needle pushing portion 42 is opened on the rear side of the first reset triangle 1, and a mounting plate 31 is fixedly installed on the rear side of the mountain plate 3, and an oblique groove hole 311 is arranged on the mounting plate 31. The end of the adjusting portion 41 has a connecting hole, so that in this embodiment, the adjusting portion 41 of the first return needle triangle 4 can be fixedly connected with the oblique groove hole 311 through a locking component. The locking component is preferably a screw, so that the first reset triangle 1 and the mounting plate 31 are used to disperse the force of the first return needle triangle 4, so as to avoid the first return needle triangle 4 being broken by the knitting needle, thereby improving the service life of the first return needle triangle 4.

[0029] And by adjusting the tightness of the locking component, the first needle return cam 4 is manually adjusted to slide along the V-shaped slide groove 12, so that the height of the first needle return cam 4 is used to adjust the reset position and height of the knitting needle, so that the knitting needle is not prone to needle movement.

[0030] Reference Figure 4 As shown, further, the thickness of the adjusting portion 41 is greater than the thickness of the needle pushing portion 42, thereby greatly enhancing the strength of the first needle cam 4 and making the first needle cam 4 less likely to break.

[0031] Reference Figure 3 As shown, it is better that the top front end surface of the first reset triangle 1 is convexly provided with a first protrusion 13. Since a V-shaped groove 12 is provided on the rear side of the first reset triangle 1, the thickness of the first reset triangle 1 is thinner. The first protrusion 13 is used to increase the strength of the top of the first reset triangle 1, so that the first reset triangle 1 is not easily worn or broken by the long needle under long-term work.

[0032] Reference Figure 2 , Figure 6 , Figure 7 As shown, further, a slide groove 21 is provided on the rear side of the second reset cam 2, and a second return stitch triangle 5 is slidably provided between the slide groove 21 and the mountain plate 3, and the surface of the mountain plate 3 has a groove 32 matching the shape of the second return stitch triangle 5, and the height of the groove 32 is greater than the height of the second return stitch triangle 5, and a height adjustment groove 52 is provided in the middle of the second return stitch triangle 5, and the second reset cam 2 and the mountain plate 3 are fixedly connected to the height adjustment groove 52 through an adjusting component, and the adjusting component is a screw. This embodiment is not repeated here, so that the height of the second return stitch triangle 5 is manually adjusted by adjusting the tightness of the adjusting component, thereby stabilizing the long needle stay position during the knitting process, such as when the coil density is too tight, the height of the second return stitch triangle 5 is increased, so that the knitting needle relaxes the coil under the action of the height of the second return stitch triangle 5, thereby facilitating the loop removal, and when the coil density is too loose, the height of the second return stitch triangle 5 is lowered, so that the knitting needle tightens the coil under the action of the height of the second return stitch triangle 5, to avoid the situation where the coil is too loose and causes automatic loop removal.

[0033] Preferably, in this embodiment, the height of the second return stitch triangle 5 is greater than the height of the second reset triangle 2, so that when the second return stitch triangle 5 is lowered to the lowest position, the lower part of the second return stitch triangle 5 is exposed from the bottom of the second reset triangle 2, so that after loosening the second return stitch triangle 5, the staff can more easily adjust the height of the second return stitch triangle 5 by pushing the lower part of the second return stitch triangle 5.

[0034] Reference Figure 8 , Fig. 9 As shown, in this embodiment, a limiting portion 22 is provided at the lower part of the slide groove 21 on the rear side of the second reset triangle 2, and the lower part of the second return needle triangle 5 has an abutment portion 51 which cooperates with the limiting portion 22 to stop, so that the limiting portion 22 is used to limit the minimum height of the second return needle triangle 5. At the same time, the upper edge and the lower edge of the groove 32 in the mountain plate 3 are used to limit the maximum limit height and the minimum limit height of the second return needle triangle 5, so that the operation of the second return needle triangle is more stable.

[0035] Reference Figure 7 , Fig. 9 As shown, the top edge of the second return needle triangle 5 is convexly provided with a flange 53, and the rear side of the second reset triangle 2 has a limiting groove 23 that cooperates with the flange 53 at the upper part of the slide groove 21. In this embodiment, the flange design is added to increase the top thickness of the second return needle triangle 5, which not only improves the strength of the second return needle triangle, but also enables the heel of the long needle to be away from the surface of the mountain plate 3, so as to avoid the long needle heel from rubbing against the mountain plate 3 when moving along the top surface of the second return needle triangle 5, thereby increasing the service life of the long needle and reducing the maintenance cost.

[0036] Reference Figure 6As shown, the top front end surface of the second reset cam 2 is convexly provided with a second protrusion 24. Since a slide groove is provided on the rear side of the second reset cam 2, the thickness of the second reset cam 2 is also thin. Therefore, the second protrusion 24 is used to increase the strength of the top of the second reset cam 2, so that the second reset cam 2 is not easily worn or broken by the long needle under long-term work, which greatly improves the service life of the second reset cam 2 and reduces the maintenance cost.

[0037] Reference Figure 1 As shown, in this embodiment, the surface of the mountain plate 3 is fixedly provided with a left flat needle triangle 6 and a right flat needle triangle 6A above the first reset triangle 1. The bottom lengths of the left flat needle triangle 6 and the right flat needle triangle 6A are greater than the length of the first return needle triangle 4. When the long needle moves upward along the trajectory of the first return needle triangle 4, it bounces up, so that the left flat needle triangle 6 or the right flat needle triangle 6A blocks the bounced long needle to ensure that the long needle moves in a straight line and avoids the long needle from slipping out of the loop due to the needle moving up.

[0038] Of course, the above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. Any modifications made according to the spirit of the main technical scheme of the utility model should be included in the protection scope of the utility model.
