Description

Technical Field

[0002] The basic principle of vortex spinning is to use a vacuum pump to evacuate the lower end of a stationary spinning machine, cut long slots on both sides for air intake, and force the airflow to form a strong vortex in the spinning machine. The fibers sucked in by the airflow rotate at high speed due to the action of the vortex to form a fiber ring. When a yarn is brought close to the small hole of the spinning head at the top of the spinning machine, it will be automatically sucked into the spinning machine and connected with the fiber ring at the cotton gathering place.

[0003] Vortex spinning technology is a highly efficient spinning method, and its spinning quality is affected by the air intake. Traditional vortex spinning air intake equipment often cannot achieve precise control of the air intake, resulting in unstable spinning quality. Moreover, when the air pressure control is poor, it is easy to cause the vacuum pump to burn out the motor. Therefore, a flow-controllable vortex spinning air intake equipment is urgently needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model provides an embodiment: a flow-controllable vortex spinning air intake device, comprising a flow control pipeline 1, a connecting pipeline 2, a vacuum pump 3, a fixed guard plate 4 and a PLC controller 5, wherein the connecting pipeline 2 is fixedly connected to one end of the flow control pipeline 1, and the input end of the vacuum pump 3 is fixedly installed at the end of the flow control pipeline 1 away from the connecting pipeline 2. When the vacuum pump 3 is started, the air inside the flow control pipeline 1 is extracted, and the air inside the connecting pipeline 2 enters the flow control pipeline 1 for replenishment to form an airflow. A valve body regulating pipe 8 is fixedly connected to the middle of the top of the flow control pipeline 1, and a fixed guard plate 4 is fixedly connected to the top of the valve body regulating pipe 8. A PLC controller 5 is fixedly installed on the top of the fixed guard plate 4, a mounting bracket 9 is fixedly connected to the inner side of the top of the fixed guard plate 4, an electric push rod 10 is fixedly installed on the inner side of the mounting bracket 9, a valve body pull rod 13 is fixedly installed on the telescopic end of the electric push rod 10, and a valve body 14 is fixedly connected to the bottom end of the valve body pull rod 13. The telescopic movement of the electric push rod 10 can drive the valve body 14 to move up and down, thereby realizing automatic opening and closing of the valve and adjusting the size of the valve opening. A pressure sensor 12 is fixedly installed on one end of the top of the flow control pipeline 1 close to the vacuum pump 3, and the sensing end of the pressure sensor 12 is located on the inner side of the flow control pipeline 1.

[0022] The top inner side of the valve body regulating tube 8 is threadedly connected with a sealing cover 11, and the valve body pull rod 13 is slidably connected to the inner side of the middle part of the sealing cover 11. Two sealing rubber rings 15 are provided on the inner side of the valve body regulating tube 8, and the sealing rubber rings 15 are nested on the outer side of the valve body 14. The sealing is performed by the sealing rubber rings 15 to reduce airflow loss and improve energy efficiency.

[0023] One end of the connecting pipe 2 away from the flow control pipe 1 is rotatably connected to a connecting piece 7, and one end of the connecting pipe 2 close to the connecting piece 7 is fixedly installed with a gas flow sensor 6. The sensing end of the gas flow sensor 6 is located inside the connecting pipe 2. The flow data inside the flow control pipe 1 is detected by the gas flow sensor 6, so that the intake volume can be adjusted by the PLC controller 5 based on the flow data.

[0024] The PLC controller 5 is respectively connected to the vacuum pump 3 , the gas flow sensor 6 , the electric push rod 10 and the pressure sensor 12 by wires, so as to automatically control the flow rate by setting a control program of the PLC controller 5 .

[0025] Working principle: During use, first set the control program through the PLC controller 5. Before use, the staff can adjust the parameter thresholds of the gas flow sensor 6, the electric push rod 10, the pressure sensor 12 and the vacuum pump 3 by setting the control program of the PLC controller 5, and then connect the connecting pipe 2 to the vortex spinning equipment through the connecting piece 7. When starting work, the PLC controller 5 starts the vacuum pump 3 and the electric push rod 10 according to the preset parameters, and the electric push rod 10 starts to contract. The telescopic end of the electric push rod 10 drives the valve body pull rod 13 to slide upward, and the sliding of the valve body pull rod 13 drives the valve body 14 to move upward. At this time, the two ends of the flow control pipe 1 are connected, and the input end of the vacuum pump 3 draws out the air inside the flow control pipe 1. At this time, the internal air pressure of the flow control pipe 1 is reduced, and the air inside the connecting pipe 2 is reduced. The air flows to the interior of the flow control pipe 1 to replenish the air pressure, and the pressure sensor 12 transmits the detected flow data to the PLC controller 5. The PLC controller 5 makes adjustments based on the flow data transmitted by the pressure sensor 12. When the flow data is lower than the preset value, the PLC controller 5 controls the vacuum pump 3 to increase the power. At the same time, the PLC controller 5 controls the electric push rod 10 to contract to drive the sealing rubber ring 15 to move upward to increase the air intake. When the flow data transmitted by the pressure sensor 12 received by the PLC controller 5 is within the preset value range, when the pressure value received by the PLC controller 5 is lower than the threshold value, the PLC controller 5 controls the electric push rod 10 to contract to increase the air intake. At the same time, the PLC controller 5 controls the vacuum pump 3 to reduce the power, thereby ensuring the air flow and adjusting the working environment of the vacuum pump 3 to avoid damage.
