Detailed Description

The invention is further described with reference to the following description and embodiments in conjunction with the accompanying drawings.

As shown in fig. 1 to 2, a layering mechanism for a double-layer yarn curtain comprises a reciprocating swing mechanism, a layering line shift lever 1.1 and a layering line 1.5 located between the two layers of yarn curtains, wherein the reciprocating swing mechanism is connected with the layering line shift lever 1.1, the reciprocating swing mechanism drives the layering line shift lever 1.1 to swing in a reciprocating mode, the layering line shift lever 1.1 acts on the layering line 1.5 to separate the two layers of yarn curtains, any one layer of yarn curtain is shifted away from a suction nozzle line taking position 2.3, and only the other layer is kept at the suction nozzle line taking position 2.3.

As shown in fig. 1 to 2, the layered deflector rod 1.1 is a cantilever deflector rod, one end of which is a free end and is a contact starting point of the layered line 1.5 and the layered deflector rod 1.1, and the other end of which is connected with the reciprocating swing mechanism, so as to avoid a space for transferring the yarn in the subsequent process.

As shown in fig. 1 to 2, the layering mechanism further comprises an ejection mechanism and a line curtain ejector rod 1.2, the ejection mechanism is connected with the line curtain ejector rod 1.2 and drives the line curtain ejector rod 1.2 to reciprocate, and when the line curtain is switched, the line curtain ejection suction nozzle is pushed out to take a line position 2.3 to assist the layering line deflector rod 1.1 and the layering line 1.5 to deflect the line curtain away from the current position.

As shown in fig. 1 to 2, the difficulty of realizing the double-layer yarn is how to ensure that the thread taking position is only a single-layer thread curtain when the suction nozzle takes the thread, in order to separate the double-layer yarn from the thread curtain, the layered thread 1.5 is arranged between the single-layer thread curtain 1.3 and the single-layer thread curtain 1.4, the layered thread 1.5 penetrates through the layered thread shifting lever 1.1 and can swing back and forth with the suction nozzle thread taking position 2.3 as a symmetrical position under the action of a layered mechanism, when the layered thread shifting lever 1.1 swings to a limit position, the single-layer thread curtain 1.4 originally left at the suction nozzle thread taking position 2.3 is shifted, and when the layered thread shifting lever 1.1 swings to another limit position, the single-layer thread curtain 1.3 shifted last time returns to the suction nozzle thread taking position 2.3 under the action of the elasticity of the yarn. Therefore, only a single-layer line curtain is arranged at the 2.3 position of the line taking position when the suction nozzle takes the line each time.

As shown in fig. 1 to 2, in order to separate two layers of yarns as much as possible within a limited swing stroke, the contact starting point 2.4 of the layered wire deflector 1.1 and the layered wire 1.5 is as close as possible to the suction nozzle wire-taking position 2.3, but at the same time, the space for transferring the yarns from the wire curtain to the upper slide wire is avoided, therefore, the layered wire deflector 1.1 is designed as a cantilever deflector, so that the contact starting point 2.4 can lean forward as much as possible while the connection and driving part of the layered wire deflector 1.1 can be arranged at the back so as not to influence the transfer process of the yarns in other processes.

The invention provides a layering mechanism for a double-layer yarn curtain, which comprises the following working processes:

in the drafting process, the thread curtain on the thread combing frame is always positioned on the straight line where the thread taking position 2.3 of the suction nozzle of the gap between the thread straightening plate A2.1 and the thread straightening plate B2.2 is positioned under the action of the self-adaptive fitting mechanism. The zero position of the layered wire deflector 1.1 is at the extreme position (as shown in fig. 2), at this time, the layered wire 1.5 already deflects one of the single-layer yarns 1.3 away from the suction nozzle wire-taking position 2.3, the suction nozzle can normally separate a single yarn from the single-layer wire curtain 1.4, when the switch needs to be switched to another single-layer wire curtain 1.3, the wire curtain ejector rod 1.2 of the layered mechanism acts to eject the suction nozzle wire-taking position 2.3 out of the single-layer wire curtain 1.4 (as shown by the dotted wire curtain ejector rod 1.2 in fig. 1), then the layered wire deflector 1.1 acts to swing to the other extreme position (as shown by the dotted layered wire deflector 1.1 in fig. 1), and finally the wire curtain ejector rod 1.2 retreats. At this moment, the single-layer curtain 1.4 is pulled away from the straight line where the line taking position 2.3 is located, and the single-layer curtain 1.3 slides back to the straight line where the line taking position 2.3 is located from the rib of the line guiding plate A2.1 under the action of the elastic force of the yarns due to the release of the layered line 1.5, and then returns to the line taking position 2.3, at the moment, the suction nozzle can normally separate a single yarn from the single-layer curtain 1.3, and the switching process of the single-layer curtain is completed.

The layering mechanism for the double-layer yarn curtain provided by the invention can save the leasing process of the double-layer yarn curtain of the drafting front passage, simplify the process flow and improve the production efficiency.

The invention provides a layering mechanism for a double-layer yarn curtain, which can be integrated on the existing heald-drawing machine, can remove the leasing link of double-layer yarns, can directly build the double-layer yarns which are drawn out by double warp beams in parallel on the original wire combing frame, directly finishes the drafting process through the heald-drawing machine carrying a direct-taking module, can save mass production cost, and ensures that the quality is more stable and controllable through a simplified process.

The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
