Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to an alloy triangular part for needle inlet that facilitates docking and positioning. Background Technology

[0002] Knitting machines typically contain multiple triangular components distributed across different guide areas, including those for needle entry, needle withdrawal, yarn take-up, and rotation. The needle entry triangular component, as a crucial part of the needle rail system, is responsible for providing a stable guide trajectory for the needles, ensuring they follow the set motion curve. Currently, commercially available needle entry triangular components lack a dedicated positioning structure, leading to potential positional errors during installation and difficulties in alignment. This results in slight misalignment between the triangular component and adjacent parts, which can affect the smoothness of needle entry, causing trajectory deviations or uneven impact forces during high-speed operation, ultimately leading to accelerated needle wear or even needle breakage. Therefore, a needle entry alloy triangular component that facilitates alignment and positioning is needed to address these technical shortcomings. Utility Model Content

[0003] The purpose of this invention is to provide an alloy triangular part for the needle inlet that facilitates docking and positioning, so as to solve the problems of difficult docking and positioning and the impact on the stable operation of the needle rail mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an alloy triangular part for easy docking and positioning of a needle inlet, comprising an outer contour plate and a triangular block, wherein the lower half of the surface of the outer contour plate is the triangular block, a guide groove is provided between the outer contour plate and the triangular block, the upper wall of the guide groove is the upper needle rail, the lower wall of the guide groove is the lower needle rail, a top edge is provided at the top of the outer contour plate, a positioning angle is machined on the left side of the top edge, two sets of protrusions are machined at the top of the top edge, two sets of inner channels are provided at the bottom of the triangular block, and a positioning block is provided on the left side of the bottom of the triangular block.

[0005] As a further technical solution of this utility model, the positioning block and the positioning angle are matched in shape, the inner channel and the protrusion are positioned, and the top edge and the inner channel are the two ends of the outer contour plate respectively.

[0006] As a further technical solution of this utility model, a screw hole is provided in the triangular block, and a back buffer groove is provided on the outer periphery of the screw hole. The back buffer groove is coaxial with the screw hole, and the axial direction of the screw hole is perpendicular to the bottom surface of the outer contour plate. A chamfer is provided around the hole opening.

[0007] As a further technical solution of this utility model, the upper needle rail and the lower needle rail form a guide groove, the guide groove is arranged along the needle inlet direction, and the guide groove is an arc-shaped groove structure.

[0008] As a further technical solution of this utility model, the outer contour plate is provided with a flared opening at the guide groove on the right side, and a flange is provided below the flared opening.

[0009] As a further technical solution of this utility model, a back buffer groove is provided on the back side of the outer contour plate along the guide groove trajectory. The back buffer groove is U-shaped concave structure and adopts curved surface transition.

[0010] As a further technical solution of this utility model, the back buffer groove and the outer contour plate form a continuous structure, and the depth of the back buffer groove is between 0.3mm and 0.5mm.

[0011] As a further technical solution of this utility model, the guide groove is coated with a micro-arc oxidation coating, and the outer contour plate is made of aluminum-silicon alloy material with a hard anodized layer applied to the surface, the oxide layer thickness being >50μm.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the alloy triangular part of the needle inlet that facilitates docking and positioning not only achieves accurate docking and positioning with small assembly error and stable needle trajectory, but also reduces guide rail wear.

[0013] By setting up positioning blocks, positioning angles, inner channels, and protrusions, with the positioning blocks and positioning angles matching in shape and the inner channels and protrusions corresponding in position, the positional accuracy during the docking process is ensured. During the operation of textile machinery, the triangular parts need to withstand the impact force of the high-speed rotating needle rail. Through the precisely matched docking structure, it is ensured that the triangular parts form a highly consistent guide rail after assembly, effectively reducing the loosening of installation caused by mechanical vibration or long-term use, and solving the problems of difficult positioning and accumulation of assembly errors affecting the stable operation of the needle rail when docking the triangular parts.

[0014] By incorporating a flared opening and a flange, an integrated buffer needle-feeding structure is formed. The flared opening is located in the guide groove on the right side of the outer contour plate, and a flange is located below the flared opening. The flared opening adopts a single-sided expansion design, which allows the knitting needle to obtain a larger envelope angle when entering the guide rail, thereby reducing the impact force at the moment of entry and improving the smoothness of needle feeding. The flange limits and constrains the needle rail to prevent the knitting needle from shifting laterally or vibrating due to high-speed impact or inertia. This solves the problem that the triangular part has a large needle-feeding impact force when operating at high speed, which can easily lead to unstable needle trajectory or needle breakage.

[0015] By incorporating a guide groove, with the upper wall of the guide groove composed of an upper needle rail and the lower wall composed of a lower needle rail, the needle feed track of the textile machinery has a smoother motion curve during the guiding process. The inner surface of the guide groove is coated with a micro-arc oxidation coating to improve hardness and wear resistance, prevent instability in the guiding process caused by surface wear, which would affect the accuracy of the needle trajectory, improve the knitting quality, and reduce wear between the needle and the guide rail. This solves the problems of increased needle feed resistance of the triangular part and inaccurate needle trajectory. Attached Figure Description
