Description

Technical Field

[0001] This application relates to the technical field of fiberglass kiln drawing equipment, specifically to a bidirectional integrated telescopic cylinder used in a fiberglass yarn drawing machine. Background Technology

[0002] The yarn head is an important winding mechanism on a fiberglass yarn drawing machine. The yarn ball or yarn cake is formed by rotating and winding the yarn on the yarn head. The yarn loading process refers to the work of winding the fiberglass yarn onto the yarn head before the drawing machine begins to draw and wind the yarn.

[0003] Existing technologies typically involve using a yarn-loading hook or loop at the end of the machine head to draw yarn onto the outer circumference. However, this method is inefficient because the yarn may not be immediately caught by the loop or hook, and slippage can occur. While clamping the yarn in the middle of the machine head and using an auxiliary yarn-winding telescopic mechanism on its outer circumference can improve efficiency, the limited installation space on the machine head necessitates simplifying the structure and connection methods of the functional components to meet the application requirements. Utility Model Content

[0004] In view of this, this application provides a bidirectional integrated telescopic cylinder for use in a glass fiber yarn drawing machine to solve all or part of the technical problems described in the background section of this application.

[0005] The innovative idea of ​​this application is to integrate two drive cylinders located on the same straight line by adopting a bidirectional integrated telescopic cylinder, and to improve the internal connection method of the cylinder, so as to reduce the space requirement of the upper head changing mechanism as much as possible while ensuring functional stability.

[0014] Preferably, the telescopic claw piston chamber cover is provided with a telescopic claw air inlet; the air supply point of the telescopic claw air inlet is located between the bottom of the collided telescopic claw piston chamber and the piston part of the telescopic claw piston rod.

[0015] When compressed air is supplied through the air inlet of the telescopic claw, the telescopic claw piston rod can be used to retract the telescopic claw back to its original position, while simultaneously compressing the telescopic elastic component; when the compressed air is disconnected, the telescopic claw piston rod can be used to extend the telescopic claw under the action of the telescopic elastic component.
