Description

A kind of multi-strand yarn automatic stitching equipment and its working method

technical field

The invention belongs to the technical field of textile machinery, and in particular relates to a multi-strand yarn automatic stitching device and a working method thereof.

Background technique

Strands are generally prepared from two or more filaments or spun yarns. When preparing strands, doubling and twisting equipment is required. The traditional method of making filaments is to first use a ring spinning machine or double twisting of filament bundles or single yarns. The machine performs initial twisting, and then the twisted two or more filament bundles or single yarns are fed into the twisting machine for double twist processing to obtain two or more finished yarns. This method has low production efficiency. It is done in steps using different machines; another way to prepare multi-twisted yarn is to use a doubling and twisting machine (one-step twister) to complete primary twisting, doubling, and double twisting on one device, which is highly efficient , Under normal circumstances, a one-step twisting machine includes a frame, a yarn guide, a primary twisting spindle, a double twisting spindle, a conveying roller, a single yarn guide part, a yarn guide part and a combined yarn guide part, and a primary twist spindle. It is driven by the upper dragon belt, and the double twisting spindle is driven by the lower dragon belt. The monofilament packages to be combined are twisted by their respective primary twisting spindles, pass through a single yarn guide part, a doubling yarn guide part, a conveying roller, and a combined yarn guide part, and then are twisted and wound by a multi-twisting spindle.

But no matter which production method is used, when two or more yarns are twisted, one of the yarns in one group is often broken, while the other yarns are not broken, resulting in missing yarns. If the turner cannot find it in time, it will cause waste yarn and waste raw materials. Yarn breaks usually occur when the twisting spindle is started up to its operating speed, especially when yarns with a large number of individual filaments or made of friction-sensitive materials such as polypropylene or polyester are used for twisting. higher frequency. After yarn breakage, it is necessary to stop the machine to guide the yarn again, which is cumbersome and wastes the spun yarn. When the yarn breakage occurs frequently at the workstation, it will have an overall adverse effect on the efficiency of the stitching equipment.

A working method of a multi-strand yarn automatic stitching device specifically includes the following steps:

Step 1: Pull out the single strand of spun yarn on the spun yarn drum 106, first pass the spun yarn under the first yarn guide rod 108, and pass above the second yarn guide rod 204, and then immerse the spun yarn in the water in the water tank 201, from the first The three yarn guide rods 205 are bypassed below, and then pass through the through hole in the center of the yarn guide slider 305 at the corresponding position, bypass the yarn guide tension wheel 307 at the corresponding position, and penetrate into the yarn collector 312.

The surface of 509 is in contact with the surface of the wire groove barrel 408;

Step 4. Start the frequency conversion motor inside the frame 401 to rotate the wire groove drum 408. The wire groove drum 408 drives the wire take-up drum 509 to rotate oppositely. Combine multiple strands of spun yarn into a single thread.

The working principle of the present invention:

When in use, put the thicker end of the spool 106 on the spool shaft 102 downward, the bottom end of the spool 106 is in contact with the spool clamping disc 103, and the clamping slider 105 in the spool clamping disc 103 is located in the spool. Inside the spool 106, the spun yarn spool 106 is pressed down, the clamping slider 105 is squeezed by the spool shaft 102, the clamping slider 105 slides along the clamping disc chute 104, the spun yarn spool 106 is clamped, and the equipment performs threading During operation, the spun yarn bobbin 106 can rotate together with the spool shaft 102 to supply yarn; when disassembling, directly pull out the spun yarn bobbin 106 upward, and the clamping slider 105 is squeezed by the spring to slide toward the center of the spool shaft 102, and the clamping slide Block 105 is automatically separated from spool 106;

The single-strand spun yarn has poor strength and is easy to break. The spun yarn passes through the first yarn guide rod 108, the second yarn guide rod 204 and the third yarn guide rod 205 in sequence, so that the spun yarn is immersed in the water in the water tank 201, and the wetted spun yarn is stretched The strength is effectively enhanced; the single strand of spun yarn passes through the yarn guide slider 305. When the spun yarn is subjected to a large pulling force, the yarn guide slider 305 slides down to compress the spring in the yarn plate chute 304, which can compress the larger yarn on the spun yarn. The tension is effectively decomposed; the lifting shaft 308 is pushed up by the spring in the stitching table 301, and when the spun yarn passes through the yarn guide tension wheel 307, the yarn guide tension wheel 307 lifts the spun yarn to provide a part of the tension for the spun yarn, and can also be used when the spun yarn is subjected to relatively high tension. When the tension is large, by compressing the spring under the lifting shaft 308, the yarn guide tension wheel 307 moves down to decompose a part of the tension;

After passing through the yarn collector 312, the spun yarn is merged into a thin wire. The thin wire passes through the wire wheel 313 and finally reaches the wire groove drum 408. The output end of the variable frequency motor in the frame 401 is fixedly connected with the active pulley 404. When the variable frequency motor starts, it drives the active pulley. The pulley 404 rotates, the driving pulley 404 drives the driven pulley 405 to rotate through the belt drive, the driven pulley 405 drives the groove cylinder shaft 406 to rotate, the groove cylinder shaft 406 finally drives the wire groove cylinder 408 to rotate, and the wire groove cylinder 408 is rotating During the process, the thin wire will swing back and forth, and the wire wheel 313 is connected to the wire bonding table 301 through the guide wheel base 314 and the guide wheel shaft 315. The friction with the wire wheel 313 prevents the thin wire from breaking due to large friction;

The bobbin support mechanism 5 makes the bobbin 509 and the wire trough 408 rotate toward each other by closely contacting and rubbing the bobbin 509 with the wire trough 408, so as to realize the function of the bobbin 509 automatically taking up the wire.
