Description

Technical Field

[0001] This utility model belongs to the field of chemical fiber technology and relates to a device that can detect the working status of a nozzle with a network of solenoid valves in real time. Background Technology

[0002] Dragon-dance yarn is a style created by alternating networked and non-networked segments along the yarn's axial direction. This yarn style is primarily achieved through a single piece of equipment: a network nozzle equipped with a solenoid valve. The working principle of this network nozzle is as follows: the opening and closing time of the solenoid valve is adjusted by a regulator in the main control cabinet, controlling whether the nozzle sprays air or not, thus creating the alternating effect of networked and non-networked segments along the yarn's axial direction.

[0003] However, network nozzles with solenoid valves may experience abnormalities during use, including continuous abnormalities and intermittent abnormalities.

[0004] When a network nozzle with a solenoid valve is consistently malfunctioning, the problem can be detected during routine inspections or finished product inspections, but the timeliness is poor, which can lead to some losses. However, when a network nozzle with a solenoid valve experiences intermittent malfunctions, these intermittent malfunctions are usually caused by poor equipment contact, making them difficult to detect during routine inspections and finished product inspections.

[0005] Patent CN203653844U discloses an automatic air-controlled network nozzle device. This device uses a yarn breakage monitor on a yarn length meter to guide the operation of the air-controlled solenoid valve. Once a yarn breaks or a yarn replacement is needed, the air-controlled solenoid valve immediately stops supplying air to the network nozzle. However, this device cannot detect the working status of the network nozzle with the solenoid valve in real time. Even if there is a continuous abnormality in the network with the solenoid valve, it cannot be detected in time. When there is an intermittent abnormality, it is very difficult to detect in daily inspections and finished product inspections.

[0006] Therefore, it is of great significance to study a device that can detect the working status of network nozzles with solenoid valves in real time in order to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to solve the problems existing in the prior art and provide a device that can detect the working status of a network nozzle with a solenoid valve in real time.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0009] A device for real-time detection of the operating status of a network nozzle with a solenoid valve, the network nozzle with a solenoid valve includes an air inlet pipe, a solenoid valve, and a network nozzle; one end of the air inlet pipe is connected to an air source, and the other end is connected to the network nozzle; the solenoid valve is disposed on the air inlet pipe, and the solenoid valve is used to periodically open and close to control the input and stop of airflow; the device for real-time detection of the operating status of the network nozzle with a solenoid valve includes wire I, wire II, wire III, connecting pipe I, connecting pipe II, air differential pressure switch, DC power supply, alarm, and time relay;

[0010] The intake pipe is equipped with connection port I and connection port II; the solenoid valve is located between connection port I and connection port II;

[0011] The air differential pressure switch includes an air inlet I, an air inlet II, and a limit switch; one end of connecting pipe I is connected to connecting port I, and the other end is connected to air inlet I; one end of connecting pipe II is connected to connecting port II, and the other end is connected to air inlet II; the limit switch is used to close when there is a difference between the air pressure input to air inlet I and the air pressure input to air inlet II, and to open when the air pressure input to air inlet I and the air pressure input to air inlet II are equal;

[0012] A time relay includes a time relay coil and a time relay switch; the time relay coil is used to control the time relay switch to close when the energizing time exceeds the closing time within one cycle of the solenoid valve's periodic opening and closing.

[0013] Specifically, after the time relay coil is energized for n seconds, the time relay coil controls the time relay switch to close. When the time relay coil is de-energized, the time relay switch opens. Let the duration of one cycle of the periodic opening and closing of the solenoid valve be a seconds, and the closing time of the solenoid valve within one cycle be b seconds; b < n < a.

[0014] The positive terminal of the DC power supply is connected to the limit switch via wire I, the limit switch is connected to the time relay coil via wire II, and the time relay coil is connected to the negative terminal of the DC power supply via wire III; the time relay switch and the alarm are connected in parallel with the time relay coil as a whole.

[0015] Both the air differential pressure switch and the time relay are existing technologies. When the solenoid valve is in the closed state, there are two possibilities: either the solenoid valve is in a periodic opening and closing phase, or the network nozzle with the solenoid valve is in an abnormal state. When the solenoid valve is in the closed state, the limit switch in the air differential pressure switch is closed. If the solenoid valve is still closed after n seconds of energizing the time relay coil, it can be known that the network nozzle with the solenoid valve is in an abnormal state, not a normal working state. At this time, the time relay coil controls the time relay switch to close, thereby triggering the alarm.

[0016] As a preferred technical solution:

[0017] As described above, the device for real-time detection of the operating status of a network nozzle with a solenoid valve further includes an intermediate relay. The intermediate relay includes an intermediate relay coil and an intermediate relay switch. The intermediate relay switch is connected in parallel with a limit switch, and the intermediate relay coil is connected in parallel with an alarm. When the intermediate relay coil is energized, it controls the intermediate relay switch to close. The intermediate relay is existing technology. When the limit switch is closed, and the time relay coil controls the time relay switch to close, the intermediate relay coil and the alarm are energized. At this time, the alarm sounds, and the intermediate relay coil controls the intermediate relay switch to close, thus locking the alarm state and preventing the network nozzle with the solenoid valve from returning from intermittent abnormality to normal, which would cause the limit switch to open and prevent the operator from detecting the abnormality (e.g., if the operator leaves or does not continuously patrol, the abnormality may not be detected in time).

[0018] As described above, the device for real-time detection of the working status of a network nozzle with a solenoid valve further includes a reset button; the reset button is disposed on the wire III and is used to control the energization and de-energization of the wire III.

[0019] When an intermediate relay is present, after the network nozzle with a solenoid valve is successfully repaired, the alarm is still powered. By using the reset button to disconnect wire III, the alarm and the intermediate relay coil are de-energized, thereby turning off the alarm and turning on the intermediate relay switch.

[0020] As described above, a device for real-time detection of the working status of a network nozzle equipped with a solenoid valve is provided. The number of network nozzles equipped with solenoid valves is multiple, and multiple network nozzles equipped with solenoid valves are simultaneously installed on a texturing machine, which is the prior art. The multiple network nozzles equipped with solenoid valves are used to network a single strand of filament. The number of air differential pressure switches, connecting pipe I, and connecting pipe II are the same as the number of network nozzles equipped with solenoid valves, and they correspond one-to-one.

[0021] The positive terminal of the DC power supply is connected to all limit switches via wire I, and all limit switches are connected to the time relay coil via wire II; all limit switches are connected in parallel; with this setup, the alarm will sound when one of the network nozzles with a solenoid valve in the feeder malfunctions.

[0022] The device described above is capable of detecting the working status of network nozzles equipped with solenoid valves in real time, wherein the number of network nozzles equipped with solenoid valves is 12.

[0023] As described above, in a device capable of real-time detection of the working status of a network nozzle equipped with a solenoid valve, the time relay is an energized delay relay.

[0024] As described above, in a device capable of real-time detection of the operating status of a network nozzle equipped with a solenoid valve, the air differential pressure switch is a diaphragm differential pressure switch.

[0025] As described above, the device for real-time detection of the working status of a network nozzle with a solenoid valve uses a multi-contact electromagnetic intermediate relay as the intermediate relay.

[0026] Beneficial effects:

[0027] (1) This utility model can ensure that when the network nozzle with the solenoid valve is in an abnormal state, it can promptly issue an alarm by using an air differential pressure switch and a time relay.

[0028] (2) The intermediate relay coil of this utility model locks the alarm state by controlling the intermediate relay switch to close, thereby preventing the limit switch from opening when the network nozzle with solenoid valve returns from intermittent abnormality to normal state, so that the operator cannot detect the abnormality.

Detailed Implementation

[0033] The present invention will be further described below with reference to specific embodiments.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0034] A device capable of real-time detection of the operating status of a network nozzle equipped with a solenoid valve, such as... Figures 1-3 As shown, it includes wire I, wire II, wire III, connecting pipe I 5, connecting pipe II 6, air differential pressure switch, DC power supply, alarm 12, time relay, intermediate relay, and reset button 13.

[0035] like Figure 1 As shown, the network nozzle with solenoid valve includes an air inlet pipe 14, a solenoid valve 1, and a network nozzle 2; one end of the air inlet pipe 14 is connected to an air source, and the other end is connected to the network nozzle 2.

[0036] There are 12 network nozzles equipped with solenoid valves, and all 12 network nozzles equipped with solenoid valves are installed on one texturing machine; each of the 12 network nozzles equipped with solenoid valves is used to network a single strand of filament.

[0037] like Figure 2 As shown, the intake pipe 14 is provided with connection port I 3 and connection port II 4;

[0038] Solenoid valve 1 is installed on the air inlet pipe 14 between connection port I 3 and connection port II 4. Solenoid valve 1 is used to periodically open and close to control the input and stop of airflow.

[0039] The air differential pressure switch is a diaphragm type differential pressure switch, which includes an air inlet I, an air inlet II, and a limit switch 7.

[0040] One end of connecting pipe I 5 is connected to connecting port I 3, and the other end is connected to air inlet I; one end of connecting pipe II 6 is connected to connecting port II 4, and the other end is connected to air inlet II;

[0041] Limit switch 7 is used to close when there is a difference between the air pressure input to air inlet I and the air pressure input to air inlet II, and to open when the air pressure input to air inlet I and the air pressure input to air inlet II are equal.

[0042] The number of air differential pressure switches, connecting pipe I 5, and connecting pipe II 6 are the same as the number of network nozzles with solenoid valves, and they correspond one-to-one.

[0043] like Figure 3 As shown, the time relay is an energized delay relay, including a time relay coil 8 and a time relay switch 9;

[0044] The time relay coil 8 is used to control the time relay switch 9 to close when the energizing time exceeds the closing time within one cycle of the periodic opening and closing of the solenoid valve 1.

[0045] The positive terminal of the DC power supply is connected to all limit switches 7 through wire I, all limit switches 7 are connected to the time relay coil 8 through wire II, and the time relay coil 8 is connected to the negative terminal of the DC power supply through wire III; all limit switches 7 are connected in parallel; the time relay switch 9 and the alarm 12 are connected in parallel with the time relay coil 8 as a whole.

[0046] The intermediate relay is a multi-contact electromagnetic intermediate relay, which includes an intermediate relay coil 10 and an intermediate relay switch 11. The intermediate relay switch 11 is connected in parallel with the limit switch 7, and the intermediate relay coil 10 is connected in parallel with the alarm 12. When the intermediate relay coil 10 is energized, the intermediate relay coil 10 controls the intermediate relay switch 11 to close.

[0047] The reset button 13 is located on wire III and is used to control the power supply and de-energization of wire III.

[0048] When an intermediate relay is present, after the network nozzle with a solenoid valve is successfully repaired, the alarm 12 is still powered. By using the reset button 13 to de-energize the wire III, the alarm 12 and the intermediate relay coil 10 are de-energized, thereby turning off the alarm 12 and turning on the intermediate relay switch 11.

[0049] The above-mentioned device is used in the production process of dragon dance yarn. When the network nozzle with the solenoid valve malfunctions, the air differential pressure switch will close the limit switch when it detects a difference between the air pressure input to inlet I and the air pressure input to inlet II, so that the time relay is energized. When the energized state exceeds the closing time of one cycle of the solenoid valve's periodic opening and closing, the time relay switch is controlled to close, so that the intermediate relay coil and the alarm are energized, thereby causing the alarm to sound. At the same time, when the intermediate relay coil detects the energization, the intermediate relay coil controls the intermediate relay switch to close, so as to lock the alarm state and prevent the network nozzle with the solenoid valve from returning to the normal state from the intermittent abnormality to the normal state, thus preventing the limit switch from opening and making it impossible for the operator to detect the abnormality.

[0050] After the network nozzle with the solenoid valve is successfully repaired, the alarm is still powered. Then, the wire III is de-energized by using the reset button, which de-energizes the alarm and the intermediate relay coil, thereby turning off the alarm and turning on the intermediate relay switch.
