Description

Technical Field

[0001] This utility model relates to the technical field of liquid level regulating devices, and in particular to a liquid level regulating device for a dyeing machine. Background Technology

[0002] In the modern printing and dyeing industry, the dyeing machine is a key production equipment, and the accuracy of its liquid level regulation directly determines the dyeing quality and production efficiency. The radar level gauge emits high-frequency electromagnetic waves through an antenna. When the electromagnetic waves encounter the surface of the dye liquor, they are reflected. The radar calculates the liquid level height based on the time difference between the emission and reception of the electromagnetic waves and the propagation speed of the electromagnetic waves. This measurement method avoids the problems of sensor corrosion and clogging that may occur in traditional contact measurement, and shows significant advantages in printing and dyeing environments with high temperature, high humidity and strong corrosiveness.

[0003] The continuous high-frequency vibrations generated during the operation of the dyeing machine cause constant changes in the stress distribution at the flange connection. Over time, the flange bolts are prone to loosening, leading to slight displacement and tilting of the flange. Simultaneously, the dyeing machine undergoes frequent heating and cooling processes during operation, causing periodic dimensional changes in the flange due to thermal expansion and contraction. The difference in expansion coefficients between flanges of different materials and the dyeing machine body exacerbates the risk of flange tilting and deformation. When the flange tilts, the propagation direction of the electromagnetic waves emitted by the radar antenna changes. The electromagnetic waves, originally perpendicular to the dyeing surface, become incident at a certain angle. This not only weakens the reflected signal intensity but also prevents the reflected waves from accurately returning to the radar receiver, causing errors in the measurement time difference calculation. Inaccurate liquid level measurement data prevents the dyeing machine's automatic control system from precisely adjusting the dye liquor injection volume, leading to an imbalance in the dye liquor ratio and ultimately a decline in product quality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a liquid level adjustment device for a dyeing machine. It solves the technical problem that the mounting flange of the radar liquid level gauge is prone to tilting and deformation due to factors such as vibration during dyeing machine operation and thermal expansion and contraction at high temperatures. When the flange tilts, the reflection path of the electromagnetic waves emitted by the radar changes, resulting in inaccurate liquid level measurement data, which in turn causes an imbalance in the dye liquor ratio and leads to a decline in product quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A liquid level regulating device for a dyeing machine includes a liquid level gauge and a flange. A monitoring mechanism for monitoring the liquid level regulating device is provided on the outside of the flange. The monitoring mechanism includes a mounting plate, an inclination sensor, and an alarm. The mounting plate is located on the outside of the flange. The inclination sensor is fixedly mounted on the upper surface of the mounting plate, and the alarm is fixedly mounted on the upper surface of the mounting plate. The inclination sensor and the alarm are electrically connected. A cable port is provided on the outside of the mounting plate.

[0007] Preferably, the lower surface of the flange is provided with a groove, the end of the mounting plate is engaged inside the groove, a limiting block for restricting the movement of the mounting plate is fixedly installed inside the groove, and a connecting hole is provided on the outside of the mounting plate, through which the mounting plate is slidably connected to the outside of the limiting block.

[0008] Preferably, the mounting plate is provided with a protective cover to shield the tilt sensor and the alarm, and the side of the protective cover corresponding to the alarm has several ventilation openings.

[0009] Preferably, a positioning frame is fixedly installed on the outside of the mounting plate, a positioning block is snapped into the inside of the positioning frame, the end of the positioning block is fixedly installed on the outside of the protective cover, a limiting spring is provided on the outside of the positioning block to restrict the movement of the positioning block, a deformation groove is opened on the outside of the positioning block, one end of the limiting spring is fixedly connected to the inside of the deformation groove, and the other end extends outward.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The tilt sensor monitors the tilt angle of the radar level gauge flange in real time and converts the angle data into an electrical signal. When the flange tilt angle exceeds a preset threshold, the electrical signal output by the tilt sensor changes and is transmitted to the alarm via the connection line. Upon receiving the abnormal signal, the alarm immediately activates the audible and visual alarm function, emitting a piercing sound and flashing lights to remind the operator that the radar level gauge flange has malfunctioned and needs to be checked and handled promptly. This effectively avoids the problem of electromagnetic wave emission path deviation caused by flange tilt, eliminates the phenomenon of inaccurate level measurement data caused by changes in the reflection path, and thus avoids dyeing quality defects caused by imbalance of dye liquor ratio, thereby ensuring product quality.

[0018] This application provides a liquid level adjustment device for a dyeing machine, which effectively solves the technical problem that the mounting flange of the radar liquid level gauge is prone to tilting and deformation due to factors such as vibration during operation of the dyeing machine and thermal expansion and contraction at high temperatures. When the flange tilts, the reflection path of the electromagnetic waves emitted by the radar changes, resulting in inaccurate liquid level measurement data, which in turn causes an imbalance in the dye liquor ratio and a decline in product quality.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the problem that the mounting flange of the radar level gauge is prone to tilting and deformation due to factors such as vibration during dyeing machine operation and thermal expansion and contraction at high temperatures. When the flange tilts, the reflection path of the electromagnetic waves emitted by the radar changes, leading to inaccurate level measurement data, which in turn causes an imbalance in the dye liquor ratio and a decline in product quality. The overall approach is as follows:

[0020] To address the problems existing in the prior art, this utility model provides a liquid level regulating device for a dyeing machine, including a liquid level gauge 1 and a flange 2. A monitoring mechanism for monitoring the liquid level regulating device is provided on the outside of the flange 2. The monitoring mechanism includes a mounting plate 3, an tilt sensor 4, and an alarm 5. The mounting plate 3 is located on the outside of the flange 2. The tilt sensor 4 is fixedly mounted on the upper surface of the mounting plate 3. The tilt sensor 4 can sense the tilt angle of the flange of the radar liquid level gauge 1 in real time. The angle change is accurately converted into an electrical signal through an internal sensitive element to continuously acquire the attitude information of the flange. The alarm 5 is fixedly mounted on the upper surface of the mounting plate 3. The tilt sensor 4 and the alarm 5 are electrically connected. The required power supply can be connected to the power supply of the dyeing machine itself.

[0021] The mounting plate 3 has a cable port 6 on its exterior, which facilitates the connection of the tilt sensor 4 and the alarm 5 to the external cable.

[0022] The lower surface of the flange 2 has a groove 7. The end of the mounting plate 3 is engaged inside the groove 7. A limiting block 8 for restricting the movement of the mounting plate 3 is fixedly installed inside the groove 7. A connecting hole 15 is provided on the outside of the mounting plate 3. The mounting plate 3 is slidably connected to the outside of the limiting block 8 through the connecting hole 15. The cooperation between the groove 7 and the limiting block 8 allows the mounting plate 3 to be quickly and accurately installed on the flange 2. When the flange 2 is connected to other flanges 2, the mounting plate 3 is located between the two flanges 2, and at this time the mounting plate 3 is restricted and cannot move.

[0023] The mounting plate 3 is equipped with a protective cover 9 to shield the tilt sensor 4 and the alarm 5, reducing the risk of moisture and dye in the dyeing machine's working environment corroding the electronic components.

[0024] The protective cover 9 has several ventilation openings 10 on the side corresponding to the alarm 5, which facilitates the sound transmission of the alarm 5 and ensures that the alarm signal can be received by the operator in a timely manner; at the same time, it promotes air circulation, helps the alarm 5 and other components to dissipate heat, and maintains their normal working performance.

[0025] A positioning frame 11 is fixedly installed on the outside of the mounting plate 3. A positioning block 12 is snapped into the inside of the positioning frame 11. The end of the positioning block 12 is fixedly installed on the outside of the protective cover 9. A limiting spring 13 for restricting the movement of the positioning block 12 is provided on the outside of the positioning block 12. A deformation groove 14 is opened on the outside of the positioning block 12. One end of the limiting spring 13 is fixedly connected to the inside of the deformation groove 14, and the other end extends outward.

[0026] Example 1

[0027] The tilt sensor 4 monitors the tilt angle of the flange of the radar level gauge 1 in real time and converts the angle data into an electrical signal. When the tilt angle of the flange exceeds the preset threshold, the electrical signal output by the tilt sensor 4 changes and is transmitted to the alarm 5 through the connection line. After receiving the abnormal signal, the alarm 5 immediately activates the audible and visual alarm function, emitting a piercing sound and flashing light to remind the operator that there is an abnormality in the flange of the radar level gauge 1, which needs to be checked and handled in time. This effectively avoids the problem of electromagnetic wave emission path deviation caused by flange tilt, eliminates the phenomenon of inaccurate liquid level measurement data caused by change of reflection path, and thus avoids dyeing quality defects caused by imbalance of dye liquor ratio, thereby ensuring product quality.

[0028] Example 2

[0029] The protective cover 9 is placed over the tilt sensor 4 and the alarm 5. At this time, the positioning block 12 enters the inner side of the positioning frame 11. During this process, the outward extension of the limiting spring 13 is compressed. After the limiting spring 13 passes the positioning frame 11, it resets to restrict the movement of the protective cover 9. At this time, the protective cover 9 is installed, reducing the risk of water vapor and dye in the dyeing machine working environment corroding electronic components. At the same time, the ventilation port 10 helps the alarm 5 to dissipate heat during operation and also facilitates the propagation of the alarm 5 sound. When the alarm 5 is activated and emits an alarm signal, the sound can be quickly propagated to the surrounding environment through these ventilation ports 10, ensuring that the operator can hear the alarm in time and make corresponding responses.

[0030] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
