Description

Technical Field

[0001] This utility model relates to the field of needle head gaskets for knitting machines, and more particularly to oil-proof gaskets for needle heads of knitting machines. Background Technology

[0002] A syringe tip pad is a very thin, ring-shaped sheet of metal or composite material that is typically installed between the syringe and syringe holder of a circular knitting machine.

[0003] Traditional gaskets rely on initial clamping force to form a static seal. Once the knitting machine operates at high speed and generates continuous vibration, the bolts may loosen slightly, and tiny gaps may appear at the mating surfaces. Traditional gaskets lack effective tracking and compensation capabilities, making them prone to separation from the mating surfaces, leading to seal failure and oil leakage. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an oil-proof gasket for the needle head of a knitting machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The needle head oil-proof gasket of the knitting machine includes a gasket body. The inner and outer rings of the gasket body are respectively provided with an inner ring assembly and an outer ring assembly. The gasket body, top, and bottom are provided with multiple concentric arc-shaped grooves. The arc-shaped grooves include groove one, groove two, and groove three arranged sequentially from the inside to the outside. Each of groove one, groove two, and groove three is provided with an auxiliary reinforcing component.

[0006] In addition, a preferred structure is that the auxiliary reinforcing component includes an auxiliary support plate, and a plurality of equally spaced supports are fixedly installed at the bottom of the auxiliary support plate.

[0007] Furthermore, in a preferred configuration, all three grooves (one, two, and three) are arc-shaped, and the bottom of the cross-section of each groove is an arc surface.

[0008] Furthermore, in a preferred configuration, when the support is installed in the corresponding arc-shaped groove, the end face of the auxiliary support plate is flush with the end face of the gasket body.

[0009] Furthermore, in a preferred configuration, the inner ring assembly comprises a plurality of stacked inner flexible rings, which are arranged vertically in sequence on the inner ring of the gasket body.

[0010] Furthermore, a preferred structure is that the outer ring assembly consists of several stacked outer flexible rings, which are arranged vertically in sequence on the outer ring of the gasket body.

[0011] The beneficial effects of this utility model are as follows: In this invention, by using the inner ring assembly, the outer ring assembly, and the arc-shaped grooves on the gasket body, top, and bottom, as well as the auxiliary reinforcing components within the arc-shaped grooves, the gasket can be tightly fitted to the surface of the connector when used on a knitting machine, forming a reliable seal and preventing oil leakage from the gasket during use.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-3 The needle head oil-proof gasket of a knitting machine includes a gasket body 1. The inner and outer rings of the gasket body 1 are respectively provided with an inner ring assembly and an outer ring assembly. The gasket body 1 has multiple concentrically distributed arc-shaped grooves at its top and bottom. These arc-shaped grooves include groove one 13, groove two 14, and groove three 15 arranged sequentially from the inside out. Each of grooves one 13, groove two 14, and groove three 15 contains an auxiliary reinforcing component. Grooves one 13, groove two 14, and groove three 15 are all arc-shaped, and the bottom of their cross-sections is an arc surface.

[0016] The auxiliary reinforcement component includes an auxiliary support plate 16, and a plurality of equally spaced supports 17 are fixedly installed on the bottom of the auxiliary support plate 16. When the supports 17 are installed in the corresponding arc-shaped grooves, the end face of the auxiliary support plate 16 is flush with the end face of the gasket body 1.

[0017] The inner ring assembly includes several stacked inner flexible rings 11, which are arranged vertically in sequence on the inner ring of the gasket body 1. The outer ring assembly includes several stacked outer flexible rings 12, which are arranged vertically in sequence on the outer ring of the gasket body 1. The multiple stacked inner flexible rings 11 and outer flexible rings 12 form multiple sealing lips. When the gasket is used on a needle head, the inner flexible rings 11 and outer flexible rings 12 undergo elastic deformation, tightly fitting against the surface of the connector. Even if there are minor unevennesses on the surface, they can be effectively filled to form a reliable seal. Furthermore, when the gasket body is used on a knitting machine, the knitting machine vibrates during high-speed operation. The inner flexible rings 11 and outer flexible rings 12 can continuously provide clamping force, finely adjusting to the vibration to maintain the durability of the seal.

[0018] In this embodiment, when the gasket is used on a knitting machine, the inner flexible ring 11 and the outer flexible ring 12 undergo elastic deformation, tightly fitting against the surface of the connector to form a reliable seal. Furthermore, when the knitting machine vibrates at high speed, the inner flexible ring 11 and the outer flexible ring 12 continuously provide clamping force, finely adjusting to the vibration to maintain the durability of the seal and prevent oil leakage from the gasket body during use.

[0019] Meanwhile, during the assembly of the gasket body, the pressure on the gasket body is evenly transmitted to the support below through the auxiliary support plate, and then from the support to the arc-shaped groove, ensuring that the entire gasket sealing surface is subjected to uniform force. After the gasket body is installed, its auxiliary support plate contacts the mating surface, and the gasket body is over-compressed, giving the gasket body a certain amount of rebound space. Moreover, the auxiliary reinforcing components (auxiliary support plate and support) act like a built-in "skeleton," greatly enhancing the compressive strength and overall rigidity of the gasket body. This prevents the soft gasket material from being squeezed out of the sealing gap under oil pressure, thus preventing damage and oil leakage. Furthermore, the groove design with an arc-shaped bottom of the cross-section can better disperse stress, reduce stress concentration points, and extend the gasket's life.

[0020] In this invention, by using the inner ring assembly and outer ring assembly, along with the arc-shaped grooves on the top and bottom of the gasket body 1 and the auxiliary reinforcing components within the arc-shaped grooves, the gasket can be tightly fitted to the surface of the connector when used on a knitting machine, forming a reliable seal and preventing oil leakage from the gasket during use.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
