[0053] Figure 1 A side view of a single-spindle single-control fancy twisting machine provided by an embodiment of the present invention, Figure 2 A front view of a single-spindle single-control fancy twisting machine provided by an embodiment of the present invention, Figure 3 A perspective view of a single-spindle single-control fancy twisting machine provided by an embodiment of the present invention, see Figure 1 , Figure 2 and Figure 3 The single-spindle single-control fancy twisting machine includes: a grooved drum 5, a ring spindle 6, a yarn detection device 8, an output roller 10, a hollow spindle 11, a front roller 12, a middle roller 13, a back roller 14 and a core roller 16; the grooved drum 5, the ring spindle 6, the output roller 10, the hollow spindle 11, the front roller 12, the middle roller 13, the back roller 14 and the core roller 16 are all driven by independent motors; the yarn detection device 8 is used to detect whether the yarn in the production process is qualified. Optionally, the yarn detection device includes a yarn count sensor; the yarn count sensor is used to emit a light signal, detect the change of the light signal when the yarn passes through, and convert the light signal into an electrical signal; the yarn count sensor is also used to extract the frequency and amplitude of the electrical signal for self-learning to form a yarn characteristic waveform. Optionally, continue to refer to Figure 1-Figure 3 The single-spindle single-control fancy twisting machine also includes: a yarn frame 1, a cradle 2, a control cabinet 3, a frame 4, a lifting device 7, a cover 9 and a start-stop button 15.

[0054] Among them, the output roller 10, the front roller 12, the middle roller 13, the back roller 14, the core roller 16 and the groove drum 5 are all driven by independent motors, and the hollow spindle 11 and the ring spindle 6 are driven by high-speed brushless motors. The yarn forming principle of the fancy twisting machine is specifically referred to Figure 4 , Figure 4The yarn forming principle diagram of the fancy twisting machine provided by the embodiment of the present invention, specifically, the No. 1 wool top passes through the creel 1 to the roller area, and moves to the hollow spindle 11 after being drafted in the roller area; the No. 2 core wire and the No. 3 core wire pass through the creel 1 to the core wire roller 16 position, and then the core wire roller 16 transports the core wire to the front roller 12 position, so that it is combined with the drafted wool top at the lower end of the front roller 12, and moves together to the hollow spindle 11; at the entrance of the hollow spindle 11, it enters the hollow spindle 11 together with the No. 4 solid wire, and at the same time, under the high-speed rotation of the hollow spindle 11, the No. 4 solid wire is firmly wound around the combined wire of the wool top and the core wire, and at the same time, it passes through the center of the hollow spindle 11 together and reaches the false twisting device at the bottom of the hollow spindle 11 to be false twisted. The yarn after false twisting is already a finished yarn, and is finally transported to the ring spindle 6 below by the output roller 10 below the hollow spindle 11 for winding to form a product.

[0055] The technical solution provided by the embodiment of the present invention has the following beneficial effects:

[0056] (1) It is very rare for a fancy twisting machine using a traditional transmission method to control the spindle difference within 15 revolutions when the hollow spindles are at 6000 r / min and the ring spindles are at 2000 r / min. Moreover, as the number of revolutions increases, the spindle difference will become larger and larger. The technical solution provided in the embodiment of the present invention directly connects the hollow spindles and the ring spindles using a high-speed brushless motor with feedback. When the hollow spindles are at 12000 r / min and the ring spindles are at 6000 r / min, the spindle difference is within 1 revolution, which effectively improves the consistency and quality of the products.

[0057] (2) The technical solution provided by the embodiment of the present invention has been tested. The actual power of a single hollow spindle is about 25W, and the ring spindle is slightly larger. However, the motors of the hollow spindle and the ring spindle of the fancy twisting machine using the traditional transmission method are 15KW respectively, which means that most of the power is consumed by the dragon belt and various tension wheels, tugs, and auxiliary wheels, resulting in a great waste. At the same time, these structures will generate a large noise when running at high speed. In addition, the noise generated by the shaking of the dragon belt during high-speed operation will make the whole machine noisy. After the single spindle and single control, the structure of the equipment is greatly simplified, which reduces the energy loss and the noise.

[0058] (3) The technical solution provided by the embodiment of the present invention adopts a "one-to-one" transmission mode, so that each set of twisting mechanisms is independent of each other, that is, a single motor drives an actuator, such as the rear roller, middle roller, front roller, core roller, hollow spindle, output roller, ring spindle, grooved drum, etc. This transmission mode effectively reduces the difficulty of production and installation of related parts, and is also easier for routine maintenance and maintenance; in addition, the use of a single motor independent transmission reduces the loss in the original mechanical transmission, plays a role in energy saving, and improves the working environment of the operator.

[0059] (4) The technical solution provided by the embodiment of the present invention innovatively introduces a yarn detection device during design. The yarn detection device has a self-learning function, which makes the transmission method more intelligent. When the yarn detection device detects that the yarn of the spindle is unqualified, the spindle will stop automatically and issue an alarm to notify the operator to handle it. Compared with the traditional transmission method, the operator needs to patrol constantly. When it is found that the yarn of a spindle is unqualified or a fault occurs, the whole machine needs to be stopped for processing, which affects the production capacity. The technical solution provided by the embodiment of the present invention can effectively reduce labor costs and improve work efficiency and production capacity.

[0060] (5) The technical solution provided in the embodiment of the present invention adopts a "one-to-one" transmission method, so that each set of twisting mechanisms is independent of each other. A separate motor drives an actuator, so that each spindle can produce different types of yarns, which can effectively meet small batch and multi-variety orders. This transmission method is more convenient and flexible, and effectively improves the flexibility of product production.

[0061] Figure 5 A flowchart of a control method for a single-spindle single-control fancy twisting machine provided by an embodiment of the present invention, see Figure 5 , the control method comprises:

[0062] S510, determining the rotation speed of the motor of each roller in a single spindle based on preset process parameters.

[0063] Among them, the values ​​of the preset process parameters can be pre-set according to production requirements through the programmable logic controller (PLC) control interface. The PLC is used as the master controller of the whole machine to plan and control the operation of each single spindle of the whole machine with different or the same process. The PLC is connected to multiple single spindle controllers through a serial bus. The preset process parameters include central control twist, ring spindle twist, drafting speed, overfeed ratio, core wire tension, untwisting coefficient and other parameters;

[0064] Specifically, the process parameters are set through the PLC control interface, and the preset process parameters are converted into the rotational speed of the motor of each roller in the corresponding single spindle, and sent to the single spindle controller through the bus.

[0065] S520. When the rotation speeds of the motors of the rollers meet the preset rotation speed thresholds of the motors, the synchronous operation of the rollers in the single spindle is controlled according to the rotation speeds.

[0066] The preset speed threshold is the upper and lower limits of the motor speed, which can be preset according to the factory parameters of the motor.

[0067] Specifically, after receiving the speed of the motor of each roller, the single spindle controller determines whether the speed of the motor of each roller meets the preset speed threshold range of the motor. If it exceeds the preset speed threshold range of the motor, the process parameters need to be reset. If it meets the preset speed threshold range of the motor, the single spindle controller controls the synchronous operation of each roller in the single spindle according to the speed of the motor of each roller, including synchronous start, synchronous stop, synchronous speed change, etc., to support the process requirements of different fancy yarns. The single spindle controller can provide microsecond synchronous control pulses to each roller, and control different rollers to run at the set speed by changing the pulse characteristics. Through the independent switch of the single spindle, the spindle can be controlled to start running according to the acquired process, or the spindle can be controlled to stop.

[0068] Optionally, determining the rotation speed of the motor of each roller in a single spindle based on preset process parameters includes:

[0069] Based on the preset process parameters and according to the preset formula, the rotation speed of each component in a single ingot is determined.

[0070] Specifically, the following formula is used to calculate the rotation speed of each component in a single spindle:

[0071] Central control twist = hollow spindle speed / output roller speed;

[0072] Ring twist = ring speed / output roller speed;

[0073] Drafting speed = front roller speed / rear roller speed;

[0074] Overfeed ratio = front roller speed / output roller speed;

[0075] Core wire tension = core wire roller speed / output roller speed;

[0076] Untwisting coefficient = ring spindle speed / hollow spindle speed.

[0077] The rotation speed of the motor of each roller in the single spindle is determined according to the rotation speed of each component in the single spindle.

[0078] Optionally, determining the rotational speed of the motor of each roller in a single spindle according to the rotational speed of each component in the single spindle includes: calculating the rotational speed of the motor of each roller in the single spindle according to the linear speed, preset diameter and preset speed ratio of each roller in the single spindle.

[0079] Specifically, the ratio of the linear speed of each roller in the single spindle to the preset diameter is calculated, and the product obtained by multiplying the ratio by the preset speed ratio is determined as the rotational speed of the motor of each roller in the single spindle.

[0080] Figure 6This is a flow chart of another control method of a single-spindle single-control fancy twisting machine provided by an embodiment of the present invention. The embodiment of the present invention further refines the above embodiment on the basis of the above embodiment. Figure 6 , the control method comprises:

[0081] S610, determining the rotation speed of the motor of each roller in a single spindle based on preset process parameters.

[0082] S620. When the rotation speeds of the motors of the rollers meet the preset rotation speed thresholds of the motors, the synchronous operation of the rollers in the single spindle is controlled according to the rotation speeds.

[0083] S630, the yarn detection device is used to detect whether the yarn in the production process is qualified. If the yarn is unqualified, the single spindle stops automatically and an alarm is sounded.

[0084] Optionally, the yarn detection device is used to detect whether the yarn in the production process is qualified, including:

[0085] The optical signal is converted into an electrical signal through the yarn detection device; the frequency and amplitude of the electrical signal are extracted for self-learning to form a yarn characteristic waveform; the actual waveform of the yarn during the production process is collected in real time; the actual waveform is compared with the yarn characteristic waveform, and if it exceeds the threshold of the yarn characteristic waveform, the yarn is determined to be unqualified.

[0086] Specifically, the yarn count sensor of the yarn detection device is used to detect whether the yarn in the production process is qualified. A photoelectric transmitting / receiving device is arranged inside the yarn count sensor. The photoelectric transmitting device emits a light signal. When the yarn passes through, it will block part of the infrared light. The photoelectric receiving device captures the change, converts the light signal into an electrical signal and sends it to the single spindle controller. The single spindle controller extracts the frequency and amplitude of the electrical signal for self-learning to form a yarn characteristic waveform. The yarn break detection function is divided into a test mode and a production mode. The production mode is the default, and the mode can be set separately through the control cabinet. In the test mode, the yarn characteristic value is extracted by the single spindle controller and fed back to the control cabinet; in the production mode, the actual waveform of the yarn in the production process is collected in real time by the yarn count sensor; the actual waveform is compared with the yarn characteristic waveform. If it exceeds the threshold of the yarn characteristic waveform, it is considered that the yarn count is out of tolerance, then it is determined that the yarn is unqualified, the spindle position stops automatically and triggers an alarm.
