Description
Technical field
The utility model is a kind of carbon fiber upper pin assembly, particularly a kind of carbon fiber upper pin assembly that adopts pressure bars with combined structure, and the drawing-off utensil for spinning machine relates to the textile machine field of components.
Background technology
In the spinning production process, the drafting system of spinning machine is to yarn quality quality decisive role.The drafting system of spinning machine is mainly by reel cage, roller, rubber roll, last cushion rubber, following cushion rubber, last pin, components and parts such as downside pin are formed, friction circle that above-mentioned components and parts form when work is being controlled between fiber and fiber and is being moved, make in the yarn and produce relative displacement between the fiber and fiber, a certain amount of Fiber Distribution is on longer fragment, reach the drawing-off purpose, on, downside pin and last, following cushion rubber form one soft and have the drawing-off proparea cushion rubber of certain pressure to grip jaw, the working face of jaw contacts the boundary that produces friction with yarn, it between last cushion rubber jaw and front roller nip the no control zone (or claiming to swim the district) of yarn, in, be the drawing-off back zone between rear roller, do not have friction circle therebetween and exist.Because the physical features diversity of fiber, exist differences such as length, thickness, varicose, thereby in no control zone, be in the fiber that free state does not have power circle control, constraint, staple fibre particularly, that movement velocity is subjected on every side is fast, the extruding of slow speed fiber, rub, involve and unordered variation, invite the dispersion of speed change point position of this fibrid bigger thus, its result be resultant yarn slightly, the generation of details, bar evenness is poor.At above-mentioned defective, the patent No. is 200820136151.X, and denomination of invention is " before and after having pressure bar go up pin ", can be in the no control zone of the proparea of drawing-off and back zone to the sliver control that presses, raising spinning yarn quality.But the forward and backward pressure bar of the said goods is the stress metal rod, and the surface cut of stress metal rod, grinding and electroplating technology be more complicated also, and production cost is higher; And the surface of stress metal rod is the absorption dust easily, and yarn is caused new pollution.
In addition then, employed on the spinning machine to go up the pin kind more, by the material branch pin and carbon fiber top pin on the steel plate arranged, and can divide jaw to sell diversity on pin and the telescopic elasticity of jaw on fixed in carbon fiber top pin again.The front end jaw of carbon fiber top pin, after long-term the use, easily produce phenomenons such as wearing and tearing, damage, distortion, and then cause cushion rubber lax or smooth, and on the flexible Elastic Carbon Fiber of jaw pin because of cushion rubber on can auto-tensioning, avoided the generation of above-mentioned phenomenon to a certain extent, but because its elastic nip stretching, extension, swing spatially, causing the key parameter of pin---middle top roller center to the size of jaw has nothing in common with each other because of circle difference directly between last cushion rubber, that is the ingot of no control zone scope that has produced the drawing-off proparea is poor, causes the yarn quality instability.
The utility model content
The purpose of this utility model is in the above-mentioned prior art, the surface cut of stress metal rod, grinding and electroplating technology be more complicated also, production cost is higher, the front end jaw easily produces wearing and tearing, damage, distortion, and the surface of stress metal rod is the defective of absorption dust easily, and a kind of carbon fiber upper pin assembly that adopts pressure bars with combined structure is provided, but simplified processing process, reduce production costs, the front end jaw does not produce wearing and tearing, damage and distortion, is not easy to adsorb dust.
The technical scheme taked of the utility model is to achieve these goals: a kind of carbon fiber upper pin assembly that adopts pressure bars with combined structure, for selling on the vertical tensioner elasticity, comprise the top-pin rack main body, left and right tensioning supporting plate, left and right coil tension spring, spacing block, the left and right pressure bar in proparea, back zone pressure bar 1 or 2; The top-pin rack main body comprises the left and right jaw of front end, and upper roller bearing gripping place and clamping bayonet socket, clamping bayonet socket are positioned at upper roller bearing gripping place rear end, are monodactyle formula or double-claw type; The left and right pressure bar in proparea is leg-of-mutton 2 right-angle side shapes at right angles, a length of side, on one side short, be mutually an angle of 90 degrees, its minor face is that injection moulding is connected at the left and right side of spacing block with the top-pin rack main body, its long limit be arranged in parallel with left and right jaw before the left and right jaw of front end; Left and right tensioning supporting plate comprises the Elastic buckle and the working face sleeve behind of working face, both sides respectively, and the front and rear direction of working face is the arch cambered surface; The back zone pressure bar be arranged in parallel at the left and right pressure bar in the clamping bayonet socket place and proparea of upper roller bearing gripping place rear end, left and right pressure bar in proparea and back zone pressure bar are the combining structure of elongated shape metal and hollow cylindrical non-metallic rods, the hollow cylindrical non-metallic rods tightly is enclosed within the elongated shape metal outer, for injection moulding connects; Or the left and right pressure bar in proparea and back zone pressure bar be the combining structure of roundlet tubular metal and hollow cylindrical non-metallic rods, and the hollow cylindrical non-metallic rods tightly is enclosed within the roundlet tubular metal outside, is that injection moulding connects; The left and right jaw of top-pin rack body front end is left and right cranse.
The cross sectional shape of described elongated shape metal can be drops, also can be small circular.
The diameter of described elongated shape metal is the 1-1.5 millimeter; The hollow cylindrical non-metallic rods is the hollow cylindrical non-metallic rods, and its wall thickness is the 1-1.5 millimeter, and the diameter of proparea pressure bar is the 3-4.5 millimeter.
The diameter of described elongated shape metal is 1 millimeter, and the wall thickness of hollow cylindrical non-metallic rods is 1 millimeter, and the diameter of proparea pressure bar is 3 millimeters.
The overall diameter of described roundlet tubular metal is the 6-8 millimeter, and the wall thickness of hollow cylindrical non-metallic rods is the 1-1.5 millimeter, and the diameter of back zone pressure bar is the 8-11 millimeter.
The overall diameter of described roundlet tubular metal is 7 millimeters, and the wall thickness of hollow cylindrical non-metallic rods is 1.5 millimeters, and the diameter of back zone pressure bar is 10 millimeters.
