Wire material supplying mechanism of tubular braided fabric braiding machine

Abstract

The invention is a thread feeding mechanism for tubular braided fabric braiding machine, composed of machine frame and thread tension adjust mechanism composed of tension detecting mechanism and braking device, where the tension detecting mechanism is composed of fixed roller group and floating roller mechanism, wherein the floating roller mechanism is composed of floating roller, supporting shaft and drive rod, and there is cut groove arranged in the machine frame, the supporting shaft is arranged in the cut groove and fixed with the drive rod, the drive rod is arranged in the machine tool through a base and a guide roller group, the medium segment of the drive rod is a truncation cone, the braking device is composed of mechanical arm and braking hoof, wherein the mechanical arm is arranged on the machine frame through a rotating shaft and a screw run through the mechanical arm, wherein one end of the screw contacts with the truncation cone. The invention adopts floating roller to detecting thread tension, and the moving direction of the drive rod is particular to the radius of a rotary table, able to overcome the centrifugal force of the rotary table and prevent the occurrence of axial offset of the drive rod and ensure normal auto adjustment of thread tension.

Description

Technical field: [0001] The invention relates to a tubular braid manufacturing device, in particular to a raw material wire feeding device in the tubular braid manufacturing device, in particular to a wire supply mechanism for a tubular braid manufacturing machine. Background technique: [0002] The tubular braided body manufacturing machine is a device that weaves metal wires or organic polymer fibers into a tubular object. The tubular braided body manufacturing machine in the prior art consists of a rotary table, a wrapping device and a plurality of wire supply devices. The plurality of wire supply devices described above are arranged along the circumference of the turntable, and the wrapping device is arranged above the center of the turntable. There is a hole in the center of the turntable. The body enters the wrapping device from the central hole of the rotary table, and at the same time, the metal wire or organic polymer fiber as the raw material of the tubular braid i...

AI Technical Summary

Problems solved by technology

[0003] The technical problem in the prior art to be solved by the present invention is: since the wire supply device in the prior art tubular braid manufacturing machine is composed of a frame, a feeding reel and a wire tension adjustment mechanism, the wire tension adjustment mechanism It is also composed of a brake device and a tension detection mechanism. The tension detection mechanism is composed of a special-shaped cam plate and a roller set respectively arranged on the frame and the special-shaped cam plate. The working method is that the wire acts on the roller on the special-shaped cam plate during work The pressure of the special-shaped cam plate is used to rotate the special-shaped cam plate, so that the special-shaped cam plate drives the brake part in the brake device, thereby changing the braking force on the feeding reel and adjusting the tension of the wire. The centrifugal force on the special-shaped cam plate and the brake device in each wire supply device on the circumferential position of the table increases significantly, and at the same time, the conveying speed of the wire increases, and the force of the wire acting on the special-shaped cam plate changes disorderly and frequently. At the same time, the special-shaped cam plate And the action of the braking device is also affected by the centrifugal force, resulting in inaccurate braking force on the feeding reel, and then there are problems such as uneven spiral wrapping of the winding and broken wire of the raw material.
