Description

 Rapping machine for racket stringing machine  

The present invention relates to a racquet stringing machine, and more particularly to a thread slinger for a racquet stringing machine.

Tennis racket and badminton racket, using elastic racquet line to form a stretched mesh hitting surface in the ring frame latitude and longitude, the ball hitting surface varies with the player's personal habits. The degree of tension of the ball striking surface depends on the force of stretching the racquet line when the racquet string is woven, and the racquet line is tight and the tensile stress value is generated, so that the woven racquet thread is easy to perform and the racquet line tensile stress value With precise control, the racquet stringing machine is used to perform the stringing of the racket.

When the racquet is threaded, the racquet line rewinds around the line segments in the frame, and the tension is pulled by the cable pulling system of the stringing machine, and the tensile stress generated by the stretching of the wire segment rises to the required value, and the wire clamp is used. Holding the line segment, the tensile stress of the line segment is maintained to facilitate the twisting of the subsequent line segments; in general, the line of the racket line used by the tennis racket and the badminton racket is different, the racket line of the tennis racket is thicker, and the racket of the badminton racket is relatively thick. The wire is thinner, and the wire clamper needs to adjust the width of the jaw with the wire diameter of the racket wire. Otherwise, the narrower jaw can be used for clamping the racket wire with different thickness and diameter, but it may pinch the thick wire diameter. The racquet line affects the strength of the racquet line, and the wider nipple cannot effectively hold the racquet line of the thin wire diameter.

The new patent publication No. 417495 discloses a wire clamp device for a racquet stringing machine, which mainly comprises a clamping unit, a fastening unit, a connecting pillar and an adjusting ring seat, wherein the clamping unit comprises two collapsible clamps and two springs. In the inner body and the clamping seat, the next unit has an upper and lower movable actuating handle, and the unit is clamped to the second steel ball and a spring to abut the clamping seat of the clamping unit, the clip掣The unit has two adjusting bolts to adjust the clamping position of the clamping unit to move back and forth, the connecting pillar is connected with the clamping unit and the clamping unit, and the adjusting ring seat is screwed into the rear side of the clamping unit for adjusting the body and the clamping unit of the clamping unit The clamp of the seat is tight.

A nip which provides a racquet line is formed between the body and the clamping seat, and the adjusting ring seat is rotated, which can promote the displacement of the splicing block of the connecting struts of the connecting struts, and adjust the width of the nipple with the wire diameter of the racquet line, and the racquet frame is worn. During the process of forming the ball striking surface, the racquet string needs to be repeatedly operated to move the handle, thereby clamping the line segment of the racquet line and releasing the clamping of the line segment, but since the racquet line is relatively clamped by the body and the cradle, the racquet The wire pair body and the clamping seat form a resistance, which is easy to cause the adjusting ring seat and the connecting strut to gradually shift with each other, causing the width of the pinch to gradually expand. Therefore, in the process of performing the threading operation, it is necessary to rotate the adjusting ring seat at a timely time to adjust the pinch. The width allows the body and the holder to effectively hold the racket line, resulting in cumbersome threading operations.

The main object of the present invention is to provide a wire gripper for a racquet stringing machine. By means of the backstop structure, the adjustment ring is prevented from rotating during the threading operation, and the reliability of the stringer to make the racquet line is improved.
