Description

Technical Field

[0001] This application relates to the technical field of fiberglass production, and particularly to a head support mechanism for a reciprocating head drawing machine. Background Art

[0002] A fiberglass drawing machine is a special equipment for the production of fiberglass yarn drawing. There is a shuttle forced wire arranging method, called a direct yarn drawing machine, and the wound yarn cake is cylindrical. There is also a type that uses a wire arranging device, called a cheese drawing machine. Since the yarn is passively arranged by the wire arranging device, the wound yarn cake is in the shape of a spindle, and the weight cannot be increased. It is necessary to reciprocate the width through the wire arranging assembly, resulting in a larger spindle shape, more serious layer difference, and easier deformation and collapse, which affects the subsequent processes, cannot achieve large package weight increase, and also affects the quality improvement of the product. With the continuous development of fiberglass towards high-end products, the reciprocating head process in drawing can solve the above problems.

[0003] Although there have been reciprocating head drawing machines on the market, the equipment is large and the structure is complex. The head assembly is heavy and has a large inertia, which affects the formation of the reciprocating cheese. It cannot be used for fine yarn and more sub-drawing of ultra-long heads. Therefore, it is urgent to develop a head support mechanism for a reciprocating head drawing machine that can improve the stability when the head makes telescopic and rotational movements.
