As described in the background art, a conventional two-for-one twister, such as the village No.36N two-for-one twister, uses a conventional single-spindle switch to control the start and stop of a single-spindle motor, please refer to fig. 1, the on-off of the switch is switched on and off by the lever principle, the schematic diagram is shown in fig. 1, the switch is turned on, and the single-spindle twisting motor is started; and when the switch is disconnected, the single-spindle twisting motor stops, and the start and stop of the motor are directly controlled through the switch. However, due to long-term operation, the switch contacts are easy to collect dust to cause poor contact, so that the switch is disconnected, and the twisting motor stops rotating. Since 2011, poor contact is caused in the switch, once the poor contact is caused, the single spindle motor stops, and the yarn is not twisted after the single spindle motor stops, is continuously output through the overfeed roller and is wound on the bobbin, so that untwisted yarn is formed. The cost of replacing a new switch is high, each vehicle needs more than 6000 yuan, so that untwisted yarns with many non-human factors are generated, frequent complaints of downstream customers are caused, and great loss is caused to companies.

As an example, referring to fig. 2, an embodiment of the present invention provides a start/stop control system for controlling the start or stop of a two-for-one twister, which includes a single-spindle twisting motor 10, a winding module 20, and a boat switch 30. The single-spindle twisting motor 10 is used for twisting the doubled yarn to generate a yarn; the winding module 20 is connected with the single-spindle twisting motor 10 and is used for winding yarns; the ship-shaped switch 30 is connected to the single-spindle twisting motor 10, and is used to control the single-spindle twisting motor 10 to start or stop.

In the start-stop control system of the above embodiment, through the two contacts of the ship-shaped switch 30, one controls the double-coil relay to close the contact and the other controls the double-coil relay to open the contact, so as to accurately control the single-spindle twisting motor 10 to start or stop, when the single-spindle twisting motor 10 is started, twisted yarns are generated and wound into a cone yarn, and a untwisted yarn phenomenon caused by the fact that the single-spindle motor stops and the winding module 20 continues to wind the yarns due to poor contact is avoided.

Specifically, referring to fig. 3, a ship-shaped switch 30 is used to control a dual-coil hold-down relay, and a schematic diagram of the dual-coil hold-down relay is shown in fig. 4, where the ship-shaped switch 30 has two contacts, one of which controls a moving contact of the dual-coil relay, and the other of which controls a moving contact of the dual-coil relay. Manually dialing the switch to a starting position, closing the dynamic contact by the double-coil holding relay, and starting the single-spindle twisting motor 10; when the switch is manually switched to the stop position, the double-coil holding relay controls the break contact to be disconnected, and the single-spindle motor stops. That is, only when the switch is moved to the off end, the single-spindle twisting motor 10 will stop, so as to avoid the untwisted yarn phenomenon caused by the single-spindle motor stopping and the winding module 20 continuing to wind due to the poor dust collection contact of the single-spindle switch.

Referring to fig. 5, in one embodiment, the system further includes a main motor 40, and the main motor 40 is connected to the winding module 20 for providing winding power to the winding module 20.

In one embodiment, the winding module 20 includes an overfeed roller 21 and a drum 22. The overfeed roller 21 is connected with the single-spindle twisting motor 10 and is used for tensioning and transmitting the yarn 62; a drum 22 is connected to the overfeed roller 21 for winding the yarn 62 to form a package.

Specifically, the two-for-one twister drives the roller 22 and the overfeed roller 21 to rotate by the main motor 40, so as to complete the winding of the yarn 62 to form the cone yarn 63. The system further includes a tension control wheel 70, the tension control wheel 70 being connected to both the overfeed roller 21 and the single spindle twist motor 10 for properly adjusting the tension between the yarns 62, which if not properly controlled, would cause problems in the normal production process, such as frequent yarn breakage and reduced production.

In one embodiment, the winding module 20 further includes a yarn guide rod 23 and a yarn guide nozzle 24, wherein the yarn guide rod 23 is used for controlling the yarn guide nozzle 24 to move left and right; the yarn guide 24 is connected to the yarn guide bar 23 for controlling the direction of movement of the yarn 62.

Specifically, after the yarn 62 passes through the overfeed roller 21, the yarn 62 is guided by the traverse movement of the hollow yarn guide 24 on the yarn guide bar 23 to be wound onto a bobbin in a predetermined shape, thereby forming a package 63. For example, in some embodiments, the yarn guide rod 23 reciprocates under the action of the driving device, the yarn guide nozzle 24 through which the yarn 62 passes is fixedly mounted on the yarn guide rod 23, and in operation, the yarn guide rod 23 is driven by the driving device to regularly swing back and forth, and the yarn 62 can be wound into a bobbin strand by the yarn 62 in a back and forth reciprocating manner when being output through the yarn guide nozzle 24.

In one embodiment, the system further comprises a control module 50 connected to the single-spindle twisting motor 10 for controlling the single-spindle twisting motor 10 to stop when the yarn 62 breaks.

Specifically, when the conventional two-for-one twister is used for a long time, if yarn breakage occurs, the winding driving wheel and the yarn guide device are subjected to long-time air friction, so that the yarn 62 on the surface of the winding driving wheel is worn out, and 'broken filaments' are caused, thereby causing loss to a product; meanwhile, the broken yarn 62 falls into the twisting mechanism, and the subsequent twisting is disturbed. The control module 50 can detect the yarn breakage in time when the yarn breakage occurs, so as to turn off the single-spindle twisting motor 10, protect the broken yarn 62, prevent the two-for-one twister from continuing to work after the yarn breakage, and reduce the loss.

In one embodiment, the control module 50 includes a micro switch 51 and a probe 52. A microswitch 51 is connected with the control module 50 and used for disconnecting the single-spindle twisting motor 10 from a power supply based on the control of the control module 50 when the yarn 62 is broken; a probe 52 is connected to said microswitch 51 for triggering the opening of said microswitch 51 when no yarn 62 is detected.

Specifically, when the two-for-one twister is started, the doubling yarn 61 is twisted into the yarn 62, and the yarn 62 is wound into the bobbin yarn 63 through the overfeed roller 21, if the yarn 62 is broken, and the probe 52 cannot detect the yarn 62, the microswitch 51 is triggered to be switched off, so that the single spindle motor is stopped. After the worker connects the broken end, the ship-shaped switch 30 is started to control the single-spindle twisting motor 10 to start and rotate, twisting is continued, and the two-for-one twister continues to work normally.

In one embodiment, the system further comprises a spinning tank 60, the spinning tank 60 being connected to the single spindle twisting motor 10 for storing the doubled yarn 61.

In one embodiment, the control module 50 includes at least one of a single chip, an ARM, a PLC, an FPGA, and the like.

Referring to fig. 6, an embodiment of the present invention provides a two-for-one twister, which includes a housing and a cavity inside;

Specifically, the two-for-one twister further comprises an electric control cabinet 80 for providing the two-for-one twister with electric power

In the two-for-one twister of the above embodiment, the single-spindle twisting motor 10 twists the doubled yarn 61 to generate the yarn 62, the winding module 20 winds the yarn 62 to generate the bobbin yarn 63, and two contacts of the boat-shaped switch 30 control the double-coil relay on-off contact one way and the double-coil relay off-on contact one way, so as to accurately control the single-spindle twisting motor 10 to start or stop, and control the single-spindle twisting motor 10 to turn off in time when the yarn 62 is broken through the control module 50. So as to avoid the untwisted yarn caused by the fact that the single spindle motor stops and the winding module 20 continues to wind due to poor contact.
