DETAILED DESCRIPTION

[0020] To make the purpose, technical scheme and advantages of the present utility model clearer and more explicit, the following will further describe the present utility model through the drawings and examples. However, it should be understood that the specific examples described here are only used to explain the present utility model, and are not used to limit the scope of the present utility model.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0022] like Figures 1-4 As shown, a side auxiliary yarn blocking device for the traverse mechanism of a yarn doubling machine is provided. The side auxiliary yarn blocking device 1 is disposed on one side of the traverse mechanism 2 of the yarn doubling machine. The traverse mechanism 2 of the yarn doubling machine includes a tail yarn cutter mechanism 21, a traverse mechanism body 22, a winding bobbin 23, and a support shaft 24. The winding bobbin 23 and the support shaft 24 are used for the tail yarn 3 to pass through, and the tail yarn 3 is cut by the tail yarn cutter mechanism 21.

[0023] The side auxiliary yarn-blocking device 1 includes a servo motor 11, a ball screw 12, a screw nut seat 13, and a small coupling 14. The ball screw 12 is connected to one side of the servo motor 11. The small coupling 14 is located between the servo motor 11 and the ball screw 12. Connecting blocks 15 are connected to the left and right sides of the ball screw 12. The screw nut seat 13 is installed on the ball screw 12, and a T-shaped slider 131 and a yarn-blocking plate 132 are fixed on one side of it. The yarn-blocking plate 132 is used to push the tail yarn 3 laterally.

[0024] In this preferred embodiment, the left and right connecting blocks 15 are generally L-shaped structural components, with a mounting hole on one side parallel to the ball screw 12, which is used for fixed connection with the baffle 4.

[0025] In this preferred embodiment, the baffle 4 has mounting grooves 41 on the left and right sides and a guide groove 42 in the center; the guide groove 42 is used for the end protrusion of the T-shaped slider 131 to slide.

[0026] In this preferred embodiment, the yarn-blocking piece 132 is an L-shaped structural component, with one side of it fixedly connected to one side of the lead screw nut seat 13, and the other side arranged horizontally and extending outward.

[0027] Working principle: The working principle of the auxiliary yarn blocking device on the side of the traverse mechanism of the yarn doubling machine mainly relies on the precise control of the servo motor, combined with the design of the mechanical structure to realize the automatic processing of the tail yarn.

[0028] The specific steps are as follows: First, when the yarn doubling machine reaches the stage where the tail yarn needs to be processed, the servo motor 11 receives a signal and starts operating. The servo motor is connected to the ball screw 12 via a small coupling 14, causing it to rotate. The rotation of the ball screw drives the screw nut seat 13 to move axially. The T-shaped slider 131 fixed on one side of the screw nut seat 13 slides along a set track under the drive of the ball screw, achieving lateral movement. (Refer to...) Figure 5, the lateral movement of the screw nut base 13 drives the yarn blocking piece 132 to move from position A to position B, thereby pushing the tail yarn 3 to be processed to one side of the winding bobbin 23, ensuring that the tail yarn can be accurately stopped at the predetermined position. After the tail yarn moves to the appropriate position, the system triggers the tail yarn cutter mechanism 21 to cut off the tail yarn, completing the entire automated processing process. Repeat the process: this process can be repeated continuously according to the winding condition of the yarn to meet the efficient operation requirement of the production line.

[0029] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement or improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
