The wind shield of the negative pressure tube is arranged, so that the air pressure consumption can be greatly reduced, and the gathering effect on the fiber strands is good. Meanwhile, under the condition of energy conservation, the negative pressure stability of each gathering groove can be ensured, the difference of the negative pressure values of the adjacent gathering grooves is greatly reduced, the consistency among spindles is favorably improved, and the yarn forming quality is improved.
Description
Technical Field
The invention relates to the technical field of textile production, in particular to a negative pressure tube device for compact spinning.
Background
At present, the compact spinning device is widely popularized and used in large areas in textile enterprises as a novel spinning process, the key of the compact spinning device is a part of the compact spinning device, the number of the compact spinning devices is large, the compact spinning device mainly integrates fibers and reduces hairiness, and under the condition that other spinning devices are the same as the spinning devices, the larger the negative pressure is, the better the compact spinning effect is, but the larger the negative pressure is, the energy consumption is increased.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention aims to provide a compact spinning negative pressure pipe device for realizing a better gathering effect under a smaller negative pressure.
The invention comprises a negative pressure pipe, a gathering groove and an air suction pipe, wherein the negative pressure pipe is arranged between a front roller and a small roller, an air suction opening of the negative pressure pipe is connected with an air box of a spinning frame through the air suction pipe, a plurality of gathering grooves for collecting hairs are formed in the surface of the negative pressure pipe, a grid ring is wound outside the gathering grooves and is in contact transmission with the small roller, and wind shields are arranged on the inner wall of the negative pressure pipe and at the gathering groove far away from the air suction opening.
6 to 8 gathering grooves are uniformly distributed along the negative pressure pipe, and 6 to 8 grid rings are matched with the gathering grooves.
The wind shields are different in length and gradually reduced from two sides of the negative pressure pipe to the middle suction opening; the angle between the wind deflector and the gathering groove is less than or equal to 45 degrees.
And the wind shields positioned at the two ends of the negative pressure pipe are sealed with the inner wall of the negative pressure pipe in the negative pressure pipe.
The negative pressure pipe, the gathering groove, the air suction pipe and the wind shield are smooth in surface, and have no burrs or edges.
Compared with the prior art, the wind shield of the negative pressure tube is arranged, so that the air pressure consumption can be greatly reduced, and the gathering effect on the fiber strands is good. Meanwhile, under the condition of energy conservation, the negative pressure stability of each gathering groove can be ensured, the difference of the negative pressure values of the adjacent gathering grooves is greatly reduced, the consistency among spindles is favorably improved, and the yarn forming quality is improved.

Detailed Description
As shown in figures 1, 2 and 3, the spinning frame comprises a negative pressure pipe 1, a gathering groove 3 and an air suction pipe 5, wherein the negative pressure pipe 1 is arranged between a front roller 14 and a small roller 16, an air suction opening 4 of the negative pressure pipe 1 is connected with an air box of a spinning frame through the air suction pipe 5, the air suction opening 4 is vertically communicated with the negative pressure pipe 1, a plurality of gathering grooves 3 for collecting hairs are formed in the surface of the negative pressure pipe 1, a grid ring 2 is wound outside the gathering grooves 3, the grid ring 2 is in contact transmission with the small roller 16, and air baffles 7 are arranged on the inner wall of the negative pressure pipe 1 and at the gathering grooves 3 far away from one side of the air suction opening 4.
6 to 8 collecting grooves 3 are uniformly distributed along the negative pressure pipe 1, and 6 to 8 grid rings 2 matched with the collecting grooves are arranged.
The wind shields 7 are different in length and gradually decrease from two sides of the negative pressure pipe 1 to the middle suction opening 4; the angle between the wind deflector 7 and the gathering groove 3 is less than or equal to 45 degrees.
And the wind shields 7 positioned at the two ends of the negative pressure pipe 1 are sealed with the inner wall of the negative pressure pipe 1 in the negative pressure pipe 1.
The negative pressure pipe 1, the gathering groove 3, the air suction pipe 5 and the wind shield 7 have smooth surfaces and no burrs or edges and corners.
When the negative pressure tube 1 is used, the negative pressure tube 1 is arranged between a front roller 14 and a small roller 16 of a spinning machine, roving 9 enters a rear leather roller 11 and a rear roller 10 drafting system through a bell mouth 8, is sequentially drafted through an upper pin 13 and a middle roller 12, drafted through a front leather roller 15 and a front roller 14, and becomes a finished yarn 18 after being drafted through a small leather roller 17 and a small roller 16, when a fiber strand formed after the roving 9 is drafted is transferred from the front roller 14 to the small roller 16, the fiber strand rotates along with the contact of a grid ring 2 and the small roller 16, short fibers or impurities in the fiber strand pass through the grid ring 2 and a gathering groove 3, and under the action of negative pressure airflow 6, the short fibers or the impurities enter the inside of the negative pressure tube 1 along a wind shield 7 and are finally discharged from an air suction. The wind deflectors 7 which are gradually reduced (half or more than one wind deflector before) can greatly reduce the air pressure consumption, and have good gathering effect on the fiber strands.
