Abstract

The invention relates to a carbon fiber tubular three-dimensional fabric dragging device for a three-dimensional circular weaving machine. The carbon-fiber tubular three-dimensional fabric dragging device comprises a rotary plate, cams, mechanical paws and a rack. The rotary plate is coaxial with the cams, and the rotary plate rotates at a constant speed. The cams are fixed, and the cams are plate-shaped groove cams. 12 sets of mechanical paws which are arranged with equal distances are arranged on the rotary plate. Each set of mechanical paws comprises two mechanical paws, wherein two fingers of one of the mechanical paws are opened and closed in the axial direction of the cams, and two fingers of the other mechanical paw are opened and closed in the radial direction of the cams. Each mechanical paw which is axially opened and closed is composed of two movable fingers, and each mechanical paw which is opened and closed in the radial direction is composed of a movable finger and a fixed finger. The fixed fingers are fixed with the rotary plate, and all the movable fingers are connected with the rotary plate through a swinging plate and a bearing. The cams are two in number, and grooves are formed in the outer sides of the cams, rollers of the end portions of mechanical paw push rods are embedded into the grooves, and the two cams are matched with the mechanical paws which are opened and closed in the axial direction and in the radial direction of the two cams. The carbon fiber tubular three-dimensional fabric dragging device can achieve continuous dragging of carbon-fiber tubular three-dimensional fabric and is low in power consumption and high in efficiency.

Description

A kind of tubulose of the carbon fiber for three-dimensional circular loom stereo fabric draw-gear

Technical field

The invention belongs to the Weaving device technical field, particularly relate to a kind of tubulose of the carbon fiber for three-dimensional circular loom stereo fabric draw-gear.

Background technology

At present the draw-gear of common circular loom comprise batch rubber roll and with the pressure roller that batches rubber roll phase compression fit, pressure roller and batch between rubber roll and be connected with press roll lever, to batch rubber roll by press roll lever and compress mutually with pressure roller, fabric is walked around and is batched after rubber roll and pressure roller on cloth beam.While batching, batch rubber roll and rotate, with the fabric friction, overcome the tension force on fabric face, and rotate by the frictional force band dynamic pressure roller batched between rubber roll and pressure roller, thereby drive fabric movement.Present pressure roller is generally cylindrical or cylindrical shape, and press roll lever is to the pressure roller two ends application of force, therefore pressure roller is excessive to exerting pressure of fabric ends, and middle part pressure is too small.For the carbon fiber stereo fabric, because of poor performance such as its anti-folding, curved, friction etc., traditional traction method can flatten carbon fiber tubulose stereo fabric, produce impression and fold, the carbon fiber stereo fabric is caused to the damage of unrepairable, frictional force is crossed conference and is made the even fracture of wildness thorn simultaneously, therefore the tradition mode of batching is not suitable for the traction of carbon fiber tubulose stereo fabric.In patent 201220271814.5, although can realize the traction laddering to carbon fibre fabric, but its complicated integral structure, the operating rate poor stability that vapour-pressure type drives, continuity is bad, drawing length is limited by rail height continuously, and the crawl vestige is arranged while batching, and carbon fiber tubulose stereo fabric is had to certain influence.

Described center of turntable is equipped with cam by bearing.

Described bottom supporting plate is bolted on rotating disk.

By bolt, two lateral bolster faggings are installed on described bottom supporting plate.

Radially retractable mechanical system design paw on described every pair of bottom supporting plate and axial retractable mechanical system design paw are staggered 90 °.

Described bottom supporting plate has 12 pairs.

The end of described moving finger and definiteness all is fixed with grip block, and the grip portions of grip block has identical curved section or knurling structure.

Beneficial effect

The present invention adopts gripper, by the mode captured, in the circumferential application of force of stereo fabric, has avoided the injury to special carbon fibre material, and employing rotary-disk type structure, realize the continuity operation of fabric, had at least 3 groups of grippers to capture fabric simultaneously, guaranteed stability.

The specific embodiment

Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only are not used in and limit the scope of the invention for the present invention is described.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.

Embodiment 1

As shown in Figure 1 to 4, a kind of tubulose of the carbon fiber for three-dimensional circular loom stereo fabric draw-gear, comprise cam 1, rotating disk 2, radially the retractable mechanical system design paw 3, axially retractable mechanical system design paw 16, push rod 4, roller 5, lateral bolster fagging 6, moving finger 7, bottom supporting plate 8, definiteness 9, groove 10, taper roll bearing 11, swinging axle 12, push rod guide plate 13, grip block 14, fabric 15, described two cam coaxials also are fixed on frame, have groove on it, roller is housed, linked the mechanical paw be fixed on rotating disk by push rod.Described rotating disk drives to rotate by motor, drive the mechanical paw of installing on it and rotate together, and then the drive push rod moves together with roller; Described paw has 12 groups of equidistant mechanical paws that arrange, every group has respectively again 2 mechanical paws, two fingers of one of them mechanical paw are along camshaft to folding, two fingers of another mechanical paw are along the radially folding of cam, catch carbon fiber tubulose stereo fabric thereby realizing is staggered 90 ° simultaneously, avoid fabric to be out of shape because of discontinuity in being pulled process.Each mechanical paw grip portions has identical concaveconvex structure, for realizing the continuous traction of reducing carbon fiber tubulose fabric.Mechanical paw circles with rotating disk 2, drive push rod and roller in cam groove moves simultaneously together, the far-end that moves to cam when mechanical paw 3 is during in rise, mechanical paw 3 is along with the variation of cam 1 groove profile, push rod moves upward, make gripper close up to start promptly carbon fiber tubulose stereo fabric, so carbon fiber tubulose stereo fabric along with the traction of mechanical paw 3 along circular motion.When mechanical paw 3 moves to near-end in backhaul, along with cam profile changes, push rod moves downward, and makes mechanical paw unclamp, and then fabric is sent in gathering-device.Other mechanical paw of 11 groups motion is consistent with the motion process of above-mentioned mechanical paw 3, circulation and so forth, thus realize the continuous traction to carbon fiber tubulose stereo fabric.In this process, make carbon fibre fabric be difficult for fold and wearing and tearing.In addition, when the diameter of stereo fabric changes, cross section that can corresponding expansion retained part, the not impact of crawl on mechanical paw, therefore can realize the reducing traction to carbon fiber tubulose stereo fabric.
