Abstract
The utility model relates to a spinning frame accessory. Now the nozzle of open-end spinning frame depends on import, which limits the application and development of the open-end spinning machine. The utility model comprises a nozzle holder. An outlet tube is opened in the nozzle holder along the axial direction. A nozzle cap is fixed at the head part. A first level nozzle is fixed in the nozzle cap. 3-6 first level nozzle holes are opened symmetrically and insequently on the lateral wall of the first level nozzle. A second level nozzle is arranged in the ink outlet tube. 4-10 second level nozzle holes are opened symmetrically and insequently on the lateral wall of the second level nozzle. A first level nozzle air inlet pipe and a second level nozzle air inlet pipe are opened in the nozzle holder. The first level nozzle, the second level nozzle, and the outlet tube are on the same axis. Adoption such structure, the twisting molding of the spinning frame can be realized. The process difficulty is small and the cost is lower.
Description
Technical field
The utility model relates to a kind of workshops accessory, especially a kind of nozzle of sir jet spinning machines.
Background technology
Along with the development of China's textile industry, sir jet spinning machines relies on advantages such as its spinning speed height, automaticity height, spinning line are lacked, yarn quality is good to be applied to textile industry more and more.At present, the employed sir jet spinning machines of China's textile industry mainly depends on import.Nozzle is as the critical component of sir jet spinning machines, because the production domesticization of also being unrealized now, and the product structure complexity of import, the use cost height, thus limited the application and the development of sir jet spinning machines.
Summary of the invention
The purpose of this utility model provide a kind of structure simple relatively, be beneficial to processing, lower-cost air-jet spinning machine nozzle.
The utility model is realized by following structure: have out spool vertically in the column type nozzle carrier, radially run through spool and have row's yarn groove.The nozzle carrier head is fixed with the cap of spraying nozzle of top perforate, forms inlet chamber between cap of spraying nozzle and nozzle carrier, in the chamber along the nozzle carrier central shaft to being fixed with first order jet nozzle and backtwisting pipe.Described first order jet nozzle is a cylinder structure, and sidewall symmetry is oblique, and to have 3～6 jet angles be 35 °～55 ° first order jet nozzle hole, and the two ends in hole are communicated with tube chamber in inlet chamber and the first order jet nozzle respectively; Described backtwisting pipe is a cylinder structure, and inwall has the backtwisting groove vertically.First order jet nozzle and backtwisting pipe are by rubber ring and cap of spraying nozzle and nozzle carrier sealing.Have the first order jet nozzle air inlet pipe in the nozzle carrier, air inlet pipe one end is communicated with inlet chamber, outside the other end pass-out nozzle carrier.Go out the secondary nozzle that is provided with cast in the spool, sidewall symmetry is oblique, and to have 4～10 jet angles be 80 °～90 ° secondary nozzle hole, the two ends in hole respectively with go out spool and secondary nozzle in tube chamber be communicated with.The two ends of secondary nozzle are by rubber ring and nozzle carrier sealing.Have the secondary nozzle air inlet pipe in the nozzle carrier, air inlet pipe one end with go out spool and be communicated with, outside the other end pass-out nozzle carrier.Described first order jet nozzle, backtwisting pipe, secondary nozzle and to go out spool be same axis, the distance in first order jet nozzle hole and secondary nozzle hole is 25～50mm.
Adopt the air-jet spinning machine nozzle of this structure can realize twisting moulding, and difficulty of processing is little, cost is lower.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the air-jet spinning machine nozzle comprises nozzle carrier 8, has out spool 12 in the nozzle carrier 8 vertically, radially runs through spool 12 row's of having yarn grooves 7.Nozzle carrier 8 heads are fixed with the cap of spraying nozzle 1 of top perforate, and 8 of cap of spraying nozzle 1 and nozzle carriers form inlet chamber 2, in this inlet chamber 2 along nozzle carrier 8 central shafts to being fixed with first order jet nozzle 4 and backtwisting pipe 5.First order jet nozzle 4 is a cylinder structure, and oblique 4 the first order jet nozzle holes (jet angle is 45 °) 3 that have of sidewall symmetry, the two ends in hole are communicated with tube chamber in inlet chamber 2 and the first order jet nozzle 4 respectively.Backtwisting pipe 5 also is a cylinder structure, and inwall has backtwisting groove 6 vertically.First order jet nozzle 4 and backtwisting pipe 5 have first order jet nozzle air inlet pipe 13 by rubber ring and cap of spraying nozzle 1 and nozzle carrier 8 sealings in the nozzle carrier 8, an end of pipe is communicated with inlet chamber 2, outside the other end pass-out nozzle carrier 8.Go out the secondary nozzle 9 that is movably equipped with cast in the spool 12, oblique 8 the secondary nozzle holes (jet angle is 88 °) 10 that have of sidewall symmetry, the two ends in hole respectively with go out spool 12 and secondary nozzle 9 in tube chambers be communicated with.The two ends of secondary nozzle 9 are by rubber ring and nozzle carrier 8 sealings.Have secondary nozzle air inlet pipe 11 in the nozzle carrier 8, an end of pipe with go out spool 12 and be communicated with, outside the other end pass-out nozzle carrier 8.First order jet nozzle 4, backtwisting pipe 5, secondary nozzle 9 and go out spool 12 on same axis, first order jet nozzle hole 3 is 36mm with the distance in secondary nozzle hole 10.
During work, the cotton stream of drawing-off is by the perforate feeding first order jet nozzle 4 on cap of spraying nozzle 1 top.Compressed air is in first order jet nozzle air inlet pipe 13, inlet chamber 2 and first order jet nozzle hole 3 enter first order jet nozzle 4 pipes, and the formation swirling eddy, makes cotton stream twist with the fingers into cotton yarn.Cotton yarn enters secondary nozzle 9 through backtwisting pipe 5 and row's yarn groove 7.Compressed air enters in secondary nozzle 9 pipes through secondary nozzle air inlet pipe 11 and secondary nozzle hole 10, forms and first order jet nozzle 4 interior reverse swirling eddies, makes the cotton yarn looping tightr.Then, cotton yarn is pulled out by going out spool 12.Backtwisting pipe 5 carries out combing by the cotton yarn of 6 pairs of first twists of backtwisting groove, and the refuse yarn of generation is cleared up by row's yarn groove 7.
