Description

A kind of both-end pressure bar top pin device
Technical field
The utility model relates to spinning new technical field, specifically a kind of can being installed on ring throstle in order to improve the both-end pressure bar top pin device of yarn quality.
Background technology
All the time, with it, adaptability to raw material and higher yarn quality gain great popularity RING SPINNING more widely.But at front roller nip, form twist triangle zone in frame spinning twist process.In twist triangle zone, the stressed difference due to the inside and outside layer of yarn fiber, shifts the fiber in twist triangle zone repeatedly, has caused fiber two ends to be usually exposed to outer formation filoplume; Outside fiber suffered tension force in twist triangle zone is maximum, and fiber suffered tension force in inner side is minimum, makes the suffered pretension of fiber in the yarn after twisting inconsistent, causes the brute force of whole yarn to be less than all single fibre strength sums in cross section; Fiber produces stretcher strain after twisting, has residual torque in yarn, causes yarn twist unstable, is unfavorable for the processing of rear road.Therefore, in the last few years, for the transformation of RING SPINNING especially around significantly reducing filoplume, improve ultimate strength, reduce the aspects such as residual torque and in theory and practice, obtained a series of great achievements, such as turning round of professor Tao Xiaoming of The Hong Kong Polytechnic University invention is appropriate, spin etc.
Upper pin is a vitals on ring spinning frame.For common upper pin, because of its once-forming, can not self-regulated apron tension, in operation process, easily cause fatigue deformation, wearing and tearing, cause the distance at working face and little iron roll center and other processing performance parameters and standard not to be inconsistent etc., make upper and lower pin with the friction and the smooth phenomenon that exist different conditions between cushion rubber.And, the back zone of fine spining machine tradition drawing-off is to adopt the drawing-off of simple roller straight line, current common upper pin cannot be controlled the fiber movement in back area draft, out later noncontrolled area is longer from rear roller for yarn, thereby cause fiber movement unstable, affect drawing-off effect, make the dry CV value of bar unstable.Therefore, comparatively extensive with the upper pin application of pressure bar at present, incidental pressure bar can effectively be strengthened back area draft to the control of fiber movement and the adaptability to fibre length.But current used upper pin all only comprises a front port, the other end installs additional or does not install pressure bar additional, makes the control of first break draft district fiber movement not ideal enough.For this, the utility model provides a kind of upper pin assembly that includes both-end pressure bar, this device comprises front port, rear port and medial arc bindiny mechanism, wherein front port is connected by medial arc bindiny mechanism with rear port, in the front portion of front port and rear port, add respectively two pressure bars, during use, upper pin is embedded in the rubber roll shaft of roller by arc intermediate connecting mechanism, simultaneously upper leather ring is tightly placed in respectively on the front and back end ports of roller and upper pin and tensioning, and rotate and drive its rotation by roller, lower apron is tightly placed in respectively front downside pin, rear downside pin, on leather ring tension frame and tensioning, the upper leather ring that is stretched in pin front port place forms front jaw with the lower apron being stretched on front downside pin, the upper leather ring that is stretched in pin rear port place forms rear jaw with the lower apron being stretched on rear downside pin, in spinning process, yarn passes through respectively pressure bar and jaw, thereby increase effective control of counter extensioin district yarn motion, improve resultant yarn comprehensive quality.
Summary of the invention
The purpose of this utility model is to provide a kind of both-end pressure bar top pin device that can improve yarn quality.
For achieving the above object, the utility model adopts and in ring spinning frame, on rubber roll, installs a kind of upper pin assembly that contains both-end pressure bar additional, described upper pin assembly comprises front port, rear port and medial arc bindiny mechanism, described front port is connected by medial arc bindiny mechanism with rear port, and bindiny mechanism is symmetric about medial arc, described port comprises left area in which the goods are in great demand, right area in which the goods are in great demand and mesozone, Yu You area in which the goods are in great demand, described left area in which the goods are in great demand is symmetric about mesozone, Yu You area in which the goods are in great demand, described left area in which the goods are in great demand is connected on mesozone by elastic connecting device, the length of protrusion mesozone, Yu You area in which the goods are in great demand, described left area in which the goods are in great demand is between 4-5mm, front portion, mesozone at described front port and rear port adds two pressure bars by dual link arc respectively, two pressure bars of described front port front portion and two pressure bars of rear port front portion are symmetric about medial arc bindiny mechanism.
During use, the Yu You area in which the goods are in great demand, left area in which the goods are in great demand of front and back end ports is connected on mesozone by elastic connecting device, and medial arc bindiny mechanism is connected on the mesozone of front port and rear port, thereby front port is connected with rear port, upper pin is embedded in the rubber roll shaft of roller by arc intermediate connecting mechanism, simultaneously two upper leather rings are tightly placed in respectively on the area in which the goods are in great demand, left and right of roller and upper pin front and back end ports and tensioning, and rotate and drive its rotation by roller, lower apron is tightly placed in respectively front downside pin, rear downside pin, on leather ring tension frame and tensioning, the upper leather ring that is stretched in pin front port place forms front jaw with the lower apron being stretched on front downside pin, the upper leather ring that is stretched in pin rear port place forms rear jaw with the lower apron being stretched on rear downside pin, two jaw structures before and after forming, in spinning process, yarn passes through respectively pressure bar and jaw, thereby increase effective control of counter extensioin district yarn motion, thereby increase effective control of counter extensioin district yarn motion, improve resultant yarn comprehensive quality.
