[0025] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", "vertical", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present utility model.

[0026] In the present utility model, unless otherwise clearly defined and limited, the terms "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0027] The following further details the tangent structure of a bead threading machine of the present utility model with reference to the drawings.

[0028] Combined with the attached Figures 1-7 , the specific implementation process of the tangent structure of a bead threading machine of the present utility model is as follows:

[0029] A tangent structure of a bead threading machine includes four major parts: a support table 1, an inlet wire bracket 2, a cutting mechanism 3, and a wire clamping mechanism 4. Each component cooperates with each other to jointly complete the automatic cutting process of the bead wire.

[0030] The support table 1 serves as the basis of the entire tangent structure and provides a stable support platform for other components.

[0031] The incoming wire bracket 2 is arranged on one side of the cutting mechanism 3 and is used to receive and guide the bead stringing wire sent from an external wire feeding device. The incoming wire bracket 2 includes a bracket plate 21, a bead stringing wire supporting plate 22, and a wire feeding device connecting plate 23. Uniformly arranged wire holes 221 are provided on the bead stringing wire supporting plate 22 to ensure that the bead stringing wire can pass through smoothly and be accurately positioned.

[0032] The cutting mechanism 3 is fixed on the support table 1 and is the core component of the wire cutting structure. The cutting mechanism 3 includes a cutting frame 31, a driving motor 32, a moving tool holder 33, and a cutting tool 34. The driving motor 32 drives the eccentric rotating assembly 36 to rotate through a gearbox 35, and then drives the moving tool holder 33 to move up and down, so as to realize the precise cutting of the bead stringing wire by the cutting tool 34. The cutting tool 34 adopts a way of staggered arrangement of an upper blade 341 and a lower blade 342 to ensure that the cutting surface is flat and free of burrs.

[0033] The eccentric rotating assembly 36 includes a power output shaft 361, an eccentric block 362, and a pushing block 363. The power output shaft 361 is connected to the power output end of the gearbox 35. The eccentric block 362 is arranged at the end of the power output shaft 361 and deviates from the axis line. The pushing block 363 is connected to the eccentric block 362 and is located on the same central axis. The rotational motion of the eccentric block 362 is converted into the linear motion of the pushing block 363, thereby driving the moving tool holder 33 to move up and down.

[0034] The moving tool holder 33 includes a tool holder plate 331 and a tool connecting piece 332. A pushing frame 3311 is provided at the center of the tool holder plate 331 for accommodating the pushing block 363 and enabling the pushing block 363 to push the tool holder plate 331 to move up and down during rotation due to the eccentricity with the power output shaft 361. The tool connecting piece 332 is detachably connected to the lower end of the tool holder plate 331, which is convenient for replacing cutting tools 34 of different specifications.

[0035] The wire clamping mechanism 4 is arranged on the other side of the cutting mechanism 3 and is used to clamp the end of the bead stringing wire to prevent the bead stringing wire from moving or falling off during the cutting process. The wire clamping mechanism 4 includes a wire clamping support frame 41 and a clamping plate 42. A wire groove 421 is provided on the clamping plate 42 for guiding and fixing the bead stringing wire.

[0036] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
