Description

Technical Field

[0001] This utility model relates to the field of textile printing and dyeing equipment technology, and in particular to a dye detection device. Background Technology

[0002] When testing dyeing equipment, a dye testing device is often used. This device is a specialized instrument used to accurately analyze the composition, concentration, and quality of dyes. Its use brings many benefits, including ensuring stable dye quality, avoiding quality problems such as color difference in products caused by dye issues, helping to optimize dyeing processes, improve production efficiency and reduce costs, and ensuring production safety and environmental protection, meeting relevant standards. It plays a key role in many industries that involve the use of dyes, such as textiles and printing and dyeing.

[0003] When the dye in the pipeline is in a normal supply state, the dye detection device continuously monitors the dye level. Once the dye level gradually decreases and reaches the preset shortage threshold, the detection device will immediately activate. It is mechanically connected to an indicator light. When a shortage is detected, it transmits a signal to the indicator light. Upon receiving the shortage signal, the indicator light will issue a shortage warning signal with a specific flashing pattern or color change. The indicator light can present the dye shortage information to the staff in a visual way. After seeing the shortage warning from the indicator light, the staff will quickly take action, prepare the required dye, and replenish the pipeline to ensure a normal dye supply, thereby ensuring the stable operation of the entire production process.

[0004] In existing technologies, some devices transport dye to the dyeing equipment via pipelines in conventional yarn dyeing production. However, these technologies suffer from several problems in dye supply monitoring. Firstly, traditional dye supply largely relies on manual inspections to determine if dye is low in the pipelines. Manual inspections are subject to drawbacks such as long intervals and significant subjective errors, failing to detect dye shortages promptly. When dye is low, the dyeing equipment continues to operate, leading to uneven color and color deviations in yarn dyeing, necessitating shutdowns for refilling, severely reducing production efficiency. Furthermore, the lack of a real-time and effective detection mechanism results in a mismatch between information acquisition and actual needs. Secondly, some existing detection devices use a single liquid level detection method, such as a level gauge. When dye is flowing in the pipeline, the level gauge is easily affected by fluid fluctuations, leading to inaccurate detection results and an inability to accurately determine the critical point when dye is about to run out, making it difficult to trigger refill operations in advance. This results in recurring dye shortages, affecting the stability of dyeing production. Therefore, a dye detection device is proposed to address these issues. Utility Model Content The present invention proposes a dye detection device, which aims to improve the problem that some existing devices cannot promptly replenish dye when it is in short supply.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A dye detection device includes a housing. A material box is fixedly connected to the internal space of the housing. A detection mechanism is arranged on the left side of the material box. The detection mechanism includes a conveying pipe. A limit rod is fixedly connected to the internal space of the conveying pipe. A limit block is fixedly connected to the top space of the limit rod. A float is slidably connected to the external space of the limit rod. Connecting rods are fixedly connected to the bottom left and right sides of the float. A contact head is fixedly connected to the bottom of the connecting rod. A trigger switch is fixedly connected to the bottom of the contact head. A connecting conduit is fixedly connected to the bottom of the trigger switch. A control component is arranged on the external side of the connecting conduit.

[0006] The above-described solution provides a dye detection device comprising a housing with a material bin fixedly connected to a hollow area within the housing. A detection mechanism is located on the left side of the material bin. Within the detection mechanism, a limiting rod and a limiting block within the conveying pipe restrict the movement range of a float. The float rises and falls with the dye level, driving a contact head via a connecting rod. When the dye level changes, the contact head triggers a switch, transmitting a signal to the control component via a connecting conduit. This design accurately monitors the dye level, provides timely feedback on dye inventory, and prevents production disruptions due to insufficient dye. Furthermore, the device is simple in structure, easy to install and maintain, and effectively improves the efficiency and accuracy of dye usage management.

[0007] As a further description of the above technical solution: The control component includes a housing, a controller is fixedly connected to the internal space of the housing, a display screen is fixedly connected to the front of the controller, operation buttons are fixedly connected to the front of the controller, and a material shortage indicator light is fixedly connected to the front of the controller.

[0008] The above solution involves a controller within the control unit housing that receives trigger switch signals, displays dye status data visually on a screen, allows for easy manual parameter setting and function adjustment via operation buttons, and illuminates a low-dye indicator when dye is insufficient. These three components work together to achieve intelligent monitoring and early warning of dye levels, improving detection efficiency and management convenience.

[0009] As a further description of the above technical solution: Multiple material conveying pipes are fixedly connected to the top space of the material box, multiple liquid inlets are fixedly connected to the front of the material box, and multiple valves are fixedly connected to the front of the liquid inlets.

[0010] The above solution allows for convenient addition of dye through multiple channels via multiple feed pipes at the top of the hopper, and multiple inlet ports on the front, combined with valves, to flexibly control dye output. The flow rate can be precisely adjusted by switching the valves on and off, which can meet different production needs, prevent dye waste, and achieve efficient management and precise use of dye.

[0011] As a further description of the above technical solution: The bottom of the outer shell is fixedly connected to multiple supports, and the top of the supports is fixedly connected to the bottom of the box.

[0012] The above solution provides stable support for the housing through multiple supports at the bottom, enhancing the overall stability of the dye detection device and preventing vibration from affecting detection accuracy. Its reasonable structural design effectively distributes the weight of the device, adapts to various installation ground environments, ensures long-term reliable operation of the device, and extends its service life.

[0013] As a further description of the above technical solution: A bracket is fixedly connected to the bottom of the conveying pipe, and the outer right side of the conveying pipe is fixedly connected to the outer left side of the outer casing.

[0014] The above solution provides stable support at the bottom of the conveying pipeline, preventing pipeline deformation from affecting dye transmission. Its right side is fixedly connected to the left side of the outer casing, ensuring a tight fit between the detection mechanism and the outer casing. This ensures a compact and stable overall structure, reduces vibration interference, guarantees accurate and reliable detection data, and improves the operational reliability of the detection device.

[0015] As a further description of the above technical solution: A door is fixedly connected to the outer side of the enclosure, and the outer side of the connecting conduit is fixedly connected to the bottom of the controller.

[0016] With the above solution, the outer door of the enclosure is easy for maintenance personnel to open, allowing them to maintain, debug, and troubleshoot internal components such as the controller. The connecting conduit is securely connected to the bottom of the controller to ensure stable signal transmission, avoid poor contact, and ensure that the control components receive detection signals in a timely manner, thus enabling reliable operation of the dye level monitoring and early warning functions.

[0017] As a further description of the above technical solution: The limiting block is externally fixedly connected to the inner wall of the conveying pipe, and the trigger switch is externally fixedly connected to the inner wall of the conveying pipe.

[0018] The above solution ensures that the limiting block and the trigger switch are firmly fixed to the inner wall of the delivery pipeline. The limiting block precisely limits the range of motion of the float, preventing it from deviating and affecting the detection. The fixed position of the trigger switch ensures the accuracy and stability of the trigger signal triggered by the float and the contact head. Together, they guarantee the high efficiency and accuracy of dye level detection.

[0019] As a further description of the above technical solution: The top side of the connecting conduit is fixedly connected to the bottom side of the conveying pipe, and the bottom side of the box is fixedly connected to the top side of the connecting conduit.

[0020] The above solution involves a tight connection between the top of the connecting conduit and the bottom of the conveying pipe, and between the bottom of the conduit and the top of the housing, achieving a stable layout for the signal transmission path. This connection method not only ensures stable signal transmission but also optimizes the internal wiring of the device, making the structure more compact and orderly, facilitating equipment installation and maintenance, and improving the overall reliability and practicality of the dye detection device.

[0021] This utility model has the following beneficial effects: In this invention, the float, based on the principle of buoyancy and the characteristic of changing with the liquid level, combined with the linkage of the connecting rod and the contact head, can sensitively detect subtle changes in the dye liquid level, promptly trigger the switch, and transmit the signal to the controller. The controller's rapid processing and analysis capabilities, combined with the real-time display on the screen, allow operators to clearly see the dye liquid level status. When the liquid level falls below the set lower limit, not only will an alarm be issued on the display screen, but a material shortage indicator light will also be illuminated. This dual reminder mechanism ensures that operators can quickly detect dye shortages, avoiding production interruptions due to insufficient dye, effectively improving the continuity and stability of the production process, while reducing manual inspection costs.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 3 and Figure 4 This utility model provides an embodiment of a dye detection device, including a housing 1, which serves a protective function and prevents dust, moisture, etc., from entering the device, ensuring its stability and reliability. A material tank 2 is fixedly connected to the internal space of the housing 1 to store the dye to be tested, providing a stable dye supply to the detection mechanism 3. The detection mechanism 3 is located on the outer left side of the material tank 2 to detect the dye level within the tank. When the level changes, it sends a signal in a timely manner so that the operator can take appropriate measures. The detection mechanism 3 includes a conveying pipe 31, which is the channel for transporting dye from the material tank 2 to the detection area, and also includes a limiting rod 32 and a float. 34 provides installation space. A limiting rod 32 is fixedly connected to the internal space area of ​​the conveying pipe 31 to provide vertical limitation for the float 34, ensuring that the float 34 can only slide up and down on the limiting rod 32, thereby accurately reflecting the changes in the dye level. A limiting block 33 is fixedly connected to the top space area of ​​the limiting rod 32 to limit the rising height of the float 34, prevent the float 34 from falling off the limiting rod 32, and ensure the normal operation of the detection mechanism 3. The float 34 is slidably connected to the external space area of ​​the limiting rod 32. Through the principle of buoyancy, the float 34 slides up and down on the limiting rod 32 as the dye level changes, driving the connecting rod 35 and the contact head 36 to move, thereby triggering the trigger switch 37. Specifically, the outer shell 1 provides protection against dust and moisture, while the internal fixed material tank 2 stores the dye to be tested and supplies it to the testing mechanism 3. The testing mechanism 3 is located on the left side of the material tank 2, which includes a conveying pipe 31, which serves as the dye conveying channel and also provides installation space for the limiting rod 32 and the float 34. The limiting rod 32 is fixed inside the pipe, and the limiting float 34 slides up and down. A limiting block 33 is fixed at the top of the limiting rod 32 to prevent the float 34 from detaching. The float 34 is slidably connected to the limiting rod 32. Utilizing the principle of buoyancy, the float slides on the limiting rod 32 as the liquid level changes, driving the connecting rod 35 and the contact head 36 to move, triggering the trigger switch 37, thereby detecting the dye liquid level in the material tank 2.

[0026] Connecting rods 35 are fixedly connected to the bottom left and right sides of the float 34, transmitting the movement of the float 34 to the contact head 36, enabling the contact head 36 to accurately trigger the trigger switch 37. The bottom of the connecting rod 35 is fixedly connected to the contact head 36. When the float 34 descends to a certain position with the dye liquid level, the contact head 36 contacts the trigger switch 37, and the trigger switch 37 generates an electrical signal, which is transmitted to the control component 39. The bottom of the contact head 36 is fixedly connected to the trigger switch 37. When the contact head 36 contacts the trigger switch 37, the switch closes, generating an electrical signal, which is transmitted to the control component 39 through the connecting pipe 38 to indicate whether the dye liquid level has reached the set lower limit. The bottom of the trigger switch 37 is fixedly connected to the connecting pipe 38, which is the channel for electrical signal transmission, ensuring that the electrical signal generated by the trigger switch 37 can be accurately transmitted to the control component 39. The control component 39 is set on the outer side of the connecting pipe 38, which is the core control part of the entire dye detection device, receiving the liquid level change signal from the trigger switch 37. Specifically, the float 34 is fixed to two sides of the bottom of the connecting rods 35, which are responsible for transmitting the movement of the float 34 to the contact head 36, ensuring that the contact head 36 is accurately triggered. The bottom of the connecting rods 35 is connected to the contact head 36. When the float 34 drops to a specific position with the dye liquid level, the contact head 36 contacts the trigger switch 37, and the trigger switch 37 closes to generate an electrical signal. This signal is transmitted to the control component 39 through the connecting pipe 38 to determine whether the dye liquid level has reached the set lower limit. The connecting pipe 38 fixed at the bottom of the trigger switch 37 is the channel for electrical signal transmission, which can ensure accurate signal transmission. The control component 39 located outside the connecting pipe 38, as the core of the dye detection device, is responsible for receiving the liquid level change signal from the trigger switch 37, thereby realizing the monitoring and feedback of the dye liquid level status.

[0027] The control component 39 includes a housing 391, which provides protection and installation space for the controller 392, and also serves to prevent dust and moisture. The controller 392 is fixedly connected to the internal space of the housing 391. It receives electrical signals transmitted by the trigger switch 37, processes and analyzes the signals, and controls the working status of the display screen 393, operation buttons 394, and low-dye indicator 395 according to a preset program. At the same time, the controller 392 can also communicate with external devices to realize remote monitoring and control. The display screen 393 is fixedly connected to the front of the controller 392, which displays the dye level information in real time. When the dye level is lower than the set lower limit, the display screen 393 will display a corresponding alarm prompt, which is convenient for operators to observe and monitor. The operation buttons 394 are fixedly connected to the front of the controller 392. Operators can use the operation buttons 394 to start, stop, and set parameters of the equipment. The low-dye indicator 395 is fixedly connected to the front of the controller 392. When the dye level is lower than the set lower limit, the low-dye indicator 395 lights up to remind the operator to replenish the dye in time. Specifically, the control component 39, including the housing 391, provides protection and installation space for the controller 392, and also protects it from dust and moisture. The controller 392 is fixed inside the housing 391, receiving electrical signals from the trigger switch 37. After processing and analysis, it controls the display screen 393, operation buttons 394, and low-material indicator 395 to work according to a preset program. At the same time, it can communicate with external devices to achieve remote monitoring and control. The display screen 393 on the front of the controller 392 can display dye liquid level information in real time. An alarm will be triggered when the liquid level is lower than the lower limit. The operation buttons 394 allow operators to start, stop, and set parameters for the equipment. The low-material indicator 395 lights up when the dye liquid level is lower than the lower limit, reminding the operator to replenish the dye in time. The entire control component 39 works together to monitor, control, and provide information feedback on the dye liquid level.

[0028] Reference Figure 1 and Figure 3 Multiple conveying pipes 4 are fixedly connected to the top space of the material tank 2 for discharging dye from the material tank 2. Multiple liquid inlets 5 are fixedly connected to the front of the material tank 2, allowing operators to easily convey dye into the material tank 2. Multiple valves 6 are fixedly connected to the front of the liquid inlets 5. By rotating the handle of the valve 6, the flow rate and on / off of the dye can be controlled to meet the dye requirements of different equipment. Multiple supports 7 are fixedly connected to the bottom of the outer shell 1 to provide support for the outer shell 1 and the box 391, ensuring the stability and levelness of the device. The top of the support 7 is fixedly connected to the bottom of the box 391. A bracket 8 is fixedly connected to the bottom of the conveying pipe 31 to provide support for the conveying pipe 31, ensuring its stability and levelness. The right side of the conveying pipe 31 is fixedly connected to the left side of the outer shell 1. Specifically, the top of the material tank 2 has multiple conveying pipes 4 for discharging dye, and the front side has multiple liquid inlets 5 to facilitate the operator to convey dye into the material tank 2. The valve 6 on the front side of the liquid inlet 5 can control the dye flow and switch by rotating the handle. Multiple supports 7 at the bottom of the outer shell 1 support the outer shell 1 and the box 391 to ensure the stability and level of the device. The bottom of the conveying pipe 31 is supported by a bracket 8 to ensure its stability and level. The right side of the conveying pipe 31 is fixed to the left side of the outer shell 1. The cooperation between them ensures the normal operation and structural stability of the dye detection device.

[0029] Reference Figure 2 and Figure 4A door 9 is fixedly connected to the outer side of the housing 391 to facilitate maintenance and repair of the controller 392 inside the housing 391. The outer side of the connecting conduit 38 is fixedly connected to the bottom of the controller 392.

All components are connected and fixed to each other to ensure that the connection of each part of the dye detection device is stable and easy to operate and maintain.

[0030] Working principle: The dye in the material tank 2 is conveyed through the conveying pipe 31. The float 34 slides up and down on the limit rod 32 according to the change of dye liquid level, relying on the principle of buoyancy. The movement of the float 34 drives the contact head 36 through the connecting rod 35. When the dye liquid level drops to a certain position, the contact head 36 contacts the trigger switch 37. The trigger switch 37 closes and generates an electrical signal. The electrical signal is transmitted to the controller 392 of the control component 39 through the connecting pipe 38. The controller 392 receives the signal, processes and analyzes it, and controls the display screen 393 to display the dye liquid level information in real time. When the liquid level is lower than the set lower limit, the display screen 393 issues an alarm prompt, and at the same time, the material shortage indicator 395 lights up to remind the operator to replenish the dye.
