Abstract
The utility model relates to textile machinery, in particular to a spiral thread-carrier of a main jet of an air-jet loom, which is also called a spiral spray needle. According to the technical scheme provided by the utility model, the spiral thread-carrier comprises an installing base body section, a rectification section and a jet pipe section, which are combined into a whole, wherein the rectification section is arranged at the front end of the installing base body section, the jet pipe section is arranged at the front end of the rectification section, the thread-carrier is axially provided with a main jet orifice which penetrates through the installing base body section, the rectification section and the jet pipe section, the front section of the main jet orifice is a jetting section, the rear section of the main jet orifice is a guiding section, the bore diameter of the guiding section is gradually shrunk from rear end to front end, a rectification groove is positioned on the rectification section, and the front end of the guiding section and the rear end of jetting section are coincident in bore diameter and are connected, and the rectification groove is vortex-shaped. When the spiral thread-carrier works, compressed air enters into the main nozzle and spirally moves forwards after being rectified by the vortex-shaped rectification groove, thereby preventing the untwisting of weft threads and enhancing the quality of textiles.
Description
Technical field
The utility model relates to textile machine, and specifically the spiral yarn guider of main nozzle of jet loom is also referred to as the spiral nozzle needle.
Background technology
The weft insertion system of existing air-jet loom generally is made up of main burner, auxilliary nozzle etc.The structure of existing main burner as shown in Figure 1.The nozzle needle of main burner screws in the main jet body, by and cap it is fixed.After compressed air enters the air admission hole of main jet body, under the effect of the rectifier tank of nozzle needle, spray along the main jet pipe.After weft yarn passes the centre bore of nozzle needle, high-speed flight under the drive of weft tracting flow, because weft yarn is in the free flight state, and itself has certain twist, and rectifier tank is the straight trough shape, so there is the untwisting phenomenon in it under state of flight, and along with the lengthening of wefting insertion length, the untwisting phenomenon is serious more; When serious, can cause fabric to have defectives such as style difference, aberration in the fabric width direction.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of untwisting phenomenon that reduces weft yarn in the pneumatic picking process is provided, can improves the spiral yarn guider of fabric quality.
The technical scheme that provides according to the utility model, described spiral yarn guider, comprise by the pedestal section is installed, the thread-carrier that rectification section and nozzle section one are connected to form, rectification section is arranged on installs pedestal section front end, nozzle section is arranged on the rectification section front end, thread-carrier axially offer the main jet hole, installation pedestal section is run through in the main jet hole, rectification section and nozzle section, the leading portion in main jet hole is the ejection section, the back segment in main jet hole is a boot segment, and the boot segment aperture is shunk gradually by the rear end forward end, offers rectifier tank on rectification section, described boot segment front end is consistent with ejection section aperture, rear end and join, and described rectifier tank is the eddy current shape.
Described rectifier tank is the eddy current shape that turns clockwise or be rotated counterclockwise.The outer wall of described rectification section is coniform that the rear end forward end shrinks gradually.
During the utility model work, compressed air advances through the laggard jet pipe spiral of becoming owner of of the rectifier tank rectification of eddy current shape, has stoped the untwisting of weft yarn, has improved the quality of fabric.

Fig. 2 is the overall structure schematic diagram of the utility model embodiment 1.
Fig. 3 is that Fig. 2 is along axial cutaway view.
Fig. 4 is the overall structure schematic diagram of the utility model embodiment 2.
The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: described spiral yarn guider comprises by pedestal section 1 is installed, the thread-carrier that rectification section 2 and nozzle section 3 one are connected to form, rectification section 2 is arranged on installs pedestal section 1 front end, nozzle section 3 is arranged on rectification section 2 front ends, thread-carrier axially offer the main jet hole, installation pedestal section 1 is run through in the main jet hole, rectification section 2 and nozzle section 3, the leading portion in main jet hole is ejection section 4b, the back segment in main jet hole is boot segment 4a, boot segment 4a is shunk gradually by the rear end forward end in the aperture, on rectification section 2, offer rectifier tank 2a, described boot segment 4b front end is consistent with ejection section aperture, 4a rear end and join, and described rectifier tank 1a is the eddy current shape.
Described rectifier tank 2a is the eddy current shape that turns clockwise (as shown in Figure 2) or be rotated counterclockwise (as shown in Figure 4).The outer wall of described rectification section 2 is coniform that the rear end forward end shrinks gradually.
During work, the installation pedestal section of thread-carrier 1 screws in the main jet body, by and cap it is fixed, after compressed air is entered by the air admission hole of main jet body, after the eddy current shape rectifier tank 2a of rectification section 2 rectification, advance along the quick spiral of main jet pipe of nozzle section 3 front portions, weft yarn there is certain twisting effect.Thereby, stop the weft yarn untwisting.
Claims (3)
