AI Technical Summary
In the existing technology, the fiberglass yarn drawing machine lacks an effective yarn guiding mechanism when guiding the fiberglass yarn to the circumference of the machine head, resulting in low guiding efficiency and affecting production efficiency.
The guide rod is tilted and rotated in combination with the horizontal extension and retraction of the pull rod. The pull rod drives the guide rod to switch between horizontal and tilted states. The rotation of the guide rod is achieved by pneumatic or electric drive, and the movement is smooth with the help of limiters and elastic return components.
This achieves efficient guidance of fiberglass yarn, reduces interference with other production processes, and improves the efficiency of head changing.

Abstract
Description
Technical Field
[0001] This application relates to the technical field of fiberglass kiln drawing equipment, specifically to a circumferential yarn guiding mechanism used in a fiberglass yarn drawing machine. Background Technology
[0002] Please refer to the Chinese patent: Automatic ejection mechanism for head replacement without cutting and control method thereof with telescopic claws and fixed claws arranged in a cross pattern, application publication number CN 118545903 A.
[0003] This patent discloses an automatic push-out mechanism for head changing without cutting, in which a smooth fixed claw and a toothed telescopic claw are cross-configured. The telescopic claw can automatically extend and retract by the cutting or conducting of compressed air, so that when changing the head, the telescopic claw can be higher than the fixed claw, and the toothed surface of the telescopic claw can efficiently capture the glass fiber filaments. When pushing the yarn, the telescopic claw can be lower than the fixed claw, so that the smooth surface of the fixed claw can bear the transition yarn to reduce the resistance during yarn pushing and avoid damage to the transition yarn loop.
[0004] In this patent, the telescopic claw's telescopic movement is radial, which is parallel telescopic movement. Therefore, although it can assist in changing the head and pushing the yarn through the telescopic movement, it cannot guide the fiberglass yarn at an angle. When it is necessary to guide the fiberglass yarn to the yarn hook on the circumference of the machine head, a new yarn guiding mechanism needs to be developed to meet production needs.

[0013] Preferably, the yarn guide rod fixing member is provided with a movable position, through which the yarn guide rod passes and is accommodated.
[0014] Preferably, the double-headed hinge includes a left upright plate, a right upright plate, and a horizontal partition plate; the left upright plate and the right upright plate are respectively disposed on both sides of the horizontal partition plate; the left upright plate, the right upright plate, and the horizontal partition plate define the installation position of the yarn guide rod and the installation position of the flat pull rod; the part of the yarn guide rod near the yarn guide rod fixing member is hinged in the yarn guide rod installation position; the end of the flat pull rod that passes through the flat pull rod fixing member is hinged in the flat pull rod installation position.

[0016] Preferably, the limiting member has a cylindrical structure; the end of the yarn guide rod that passes through the yarn guide rod fixing member is provided with a matching shaft hole structure; the limiting member is disposed in the shaft hole structure on the yarn guide rod and can rotate freely.
[0017] Beneficial technical effects:
[0018] When the horizontal pull rod moves forward, it pushes the yarn guide rod to rotate to a horizontal state. At this time, it occupies the least space in the radial direction and does not affect the completion of other production actions such as axial yarn pushing. When the horizontal pull rod moves backward, it pulls the yarn guide rod to rotate to an inclined state. At this time, it can guide the glass fiber yarn to the yarn hook on the circumference of the machine head to assist the machine head in completing the head change efficiently.

[0036] The double-headed hinge 2 includes a left upright plate 21, a right upright plate 22, and a horizontal partition plate 23; the left upright plate 21 and the right upright plate 22 are respectively arranged on both sides of the horizontal partition plate 23; the left upright plate 21, the right upright plate 22, and the horizontal partition plate 23 define the guide rod mounting position 24 and the flat tie rod mounting position 25.
[0037] The part of the yarn guide rod 1 near the yarn guide rod fixing part 4 is hinged to the yarn guide rod mounting position 24; the end of the flat tie rod 3 that passes through the flat tie rod fixing part 5 is hinged to the flat tie rod mounting position 25.
