Specific Embodiments

[0019] Please refer to the attached drawings in the specification Figure 1 and the attached Figure 2 As shown, the present utility model is a yarn guiding mechanism of a full-automatic winding machine, which is assembled from several parts such as a yarn guiding support 1, a vertical plate 2, a yarn guiding motor 3, a transmission shaft 4, a moving screw rod clamp 5, a moving screw rod 6 and a yarn guiding head 7.

[0020] Among them, the yarn guiding bracket 1 is the base of the entire yarn guiding mechanism, enabling modular production of the yarn guiding mechanism.

[0021] Two vertical plates 2 are provided and are welded to the yarn guiding bracket 1 in parallel and are perpendicularly connected to the yarn guiding bracket 1.

[0022] The yarn guiding motor 3 is installed on one of the vertical plates 2. In this embodiment, the yarn guiding motor 3 is located between the two vertical plates 2, so as to make full use of the space between the two vertical plates 2 and make the structure of the entire yarn guiding mechanism compact. A main synchronous pulley 31 is connected to the yarn guiding motor 3, and the main synchronous pulley 31 rotates driven by the yarn guiding motor 3.

[0023] The transmission shaft 4 is pivotally connected and supported on the two vertical plates 2, and a driven pulley I 41 and a driven pulley II 42 are respectively installed at both ends thereof. A synchronous belt I 81 is sleeved on the main synchronous pulley 31 and the driven pulley I 41. The yarn guiding motor 3 drives the main synchronous pulley 31, the synchronous belt I 81 and the driven pulley I 41 in sequence, and the driven pulley I 41 drives the transmission shaft 4 in linkage, and the transmission shaft 4 then drives the driven pulley II 42.

[0024] Further, a driven pulley III 21 is installed on the vertical plate 2 where the yarn guiding motor 3 is not installed. A synchronous belt II 82 is sleeved on the driven pulley II 42 and the driven pulley III 21, so that the driven pulley II 42 drives the synchronous belt II 82 and the driven pulley III 21 in sequence. In this embodiment, the main synchronous pulley 31, the driven pulley I 41, the driven pulley II 42 and the driven pulley III 21 are arranged in a 2*2 matrix, making the arrangement regular and ensuring that the lengths of the synchronous belt I 81 and the synchronous belt II 82 are the same, with good versatility.

[0025] The moving screw rod clamp blocks 5 are respectively fixed on the synchronous belt I 81 and the synchronous belt II 82 and can be respectively driven by the synchronous belt I 81 and the synchronous belt II 82. The moving screw rods 6 are respectively fixed on the moving screw rod clamp blocks 5 and are driven by the moving screw rod clamp blocks 5 to reciprocate back and forth in the front and back directions.

[0026] To limit the left-right and up-down positions of the moving screw rod 6, a V-shaped supporting pulley 61 is arranged below the moving screw rod 6, and a pressing wheel 62 is arranged above. The V-shaped supporting pulley 61 and the pressing wheel 62 are oppositely arranged and clamp the moving screw rod 6. Specifically, the V-shaped supporting pulley 61 can clamp the moving screw rod 6 to limit the left, right and lower three positions of the moving screw rod 6; the pressing wheel 62 presses down on the moving screw rod 6 to prevent the moving screw rod 6 from moving upwards.

[0027] Two mutually parallel moving screw rods 6 are provided, and each moving screw rod 6 perpendicularly passes through the yarn guiding bracket 1 and is respectively arranged outside the two vertical plates 2, making the layout reasonable. The two moving screw rods 6 are connected by a connecting rod 63 to prevent the two moving screw rods 6 from rotating.

[0028] The yarn guide head 7 is installed at one end of the yarn transfer rod 6. In this embodiment, two yarn guide heads 7 are arranged on each yarn transfer rod 6, so that the two yarn transfer rods 6 drive the four yarn guide heads 7 synchronously, and the four yarn guide heads 7 move synchronously, greatly improving the efficiency of yarn guiding.

[0029] The working principle of the yarn guiding mechanism of the full-automatic winding machine of the present utility model is as follows: The yarn guiding motor 3 rotates forward and backward, and sequentially drives the main synchronous pulley 31. The main synchronous pulley 31 is sequentially linked with the synchronous belt I 81, the driven pulley I 41, the transmission shaft 4, the driven pulley II 42, the synchronous belt II 82 and the driven pulley III 21. The above transmission is realized through the synchronous belt and the belt pulley, and its transmission is stable, the performance is reliable, and the service life is long. The reciprocating movement of the synchronous belt I 81 and the synchronous belt II 82 drives the yarn transfer rod clamp 5 to reciprocate. The yarn transfer rod clamp 5 drives the yarn transfer rod 6 to reciprocate back and forth, and drives the yarn guide head 7 to guide the yarn through the yarn transfer rod 6. By controlling the number of rotation turns of the yarn guiding motor 3, the reciprocating stroke of the synchronous belt I 81 and the synchronous belt II 82 can be adjusted, and thus the stroke of the yarn guide head 7 can be adjusted arbitrarily to meet different yarn guiding requirements.

[0030] The above specific embodiments are only preferred embodiments of the present creation, and are not intended to limit the present creation. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present creation shall be included within the protection scope of the present creation.
