Abstract

The invention discloses a telescopic drafting tube for spinning and belongs to the technical field of spinning equipment. A drafting tube body is connected with a telescopic transition tube. The outer wall of the telescopic transition tube can slide on the inner wall of the drafting tube body in an airtight mode. The end, far away from the telescopic transition tube, of the drafting tube body is provided with a yarn distributor. The yarn distributor is fixedly mounted at a drafting tube port through a connecting base. The telescopic drafting tube for spinning has the advantages that the telescopic transition tube is mounted on the drafting tube body, so that the length of the drafting tube body is adjustable, the distance between the yarn distributor at the drafting tube port and a yarn arranging plate is controllable, the ejecting angle of yarn from the port to the yarn arranging plate is controllable, and then laying of the yarn ejected to a web curtain is controllable; the wall of the drafting tube body is provided with an airflow hole or a static pressure detection device, and an air compressor is used for amplifying airflow in the drafting tube body twice, so that the yarn ejecting speed of the port is increased, and better preparation is made for laying the yarn on the web curtain.

Description

For the extension type drafting tube of spinning

technical fieldfor the extension type drafting tube of spinning, belong to spinning equipment technical field.

background technologytextile industry in process of production, silk thread pulls out by air-flow from drafting tube, due to the length restriction of drafting tube own, air-flow offers silk thread tractive force and dies down, cause using longer drafting tube, drafting tube is too short, and silk thread exports from pendulum wire plate distance, silk thread is launched to lace curtaining position and exert an influence, thereby affect normally carrying out of next process.

summary of the inventionin view of the defect that prior art exists, the object of this invention is to provide a kind of extension type drafting tube for spinning that ensures piddler quality.

For achieving the above object, the technology used in the present invention solution is: for the extension type drafting tube of spinning, drafting tube connects scalable transition conduit, described scalable transition conduit outer wall can airtight slip on drafting tube inwall, on drafting tube, be provided with sub-wire device away from one end of scalable transition conduit, sub-wire device is fixedly mounted on drafting tube port by Connection Block.

On described drafting tube, device for detecting static pressure is installed, in the time that in pipe, stream pressure is not enough, device for detecting static pressure can feed back to air-flow distributor by detection information, and air-flow distributor increases throughput according to instruction, improves stream pressure in drafting tube.

Described drafting tube is provided with airflow hole, and described airflow hole perforate direction and tube wall are 20-45 degree angle, and described airflow hole connects gas blow pipe outward, and gas blow pipe connects air compressor machine, and sub-wire device is fixedly mounted on drafting tube port by Connection Block.

For the extension type drafting tube of spinning, its beneficial effect is: scalable transition conduit is installed on drafting tube, make drafting tube length adjustable, drafting tube port sub-wire device is controlled apart from pendulum wire plate distance, it is controlled that silk thread injects to pendulum wire plate angle from port, then makes silk thread launch piddler after lace curtaining controlled; On drafting tube tube wall, airflow hole is installed, is utilized air compressor machine to strengthen managing interior air-flow secondary, accelerate port wire vent speed, for lace curtaining piddler has been done better preparation.
