Description

Technical Field

[0001] This invention relates to the field of omnidirectional temperature measurement technology, and in particular to an omnidirectional fluid temperature measurement device for a yarn guiding device. Background Technology

[0002] The yarn guiding device generates heat during operation, primarily due to friction and high-speed rotation. The causes of this heat generation can be attributed to the following key aspects:

[0003] Friction between the yarn guide, the yarn, and the bearings; during winding and twisting processes, the yarn on the yarn bobbin forms a rotating "air ring." This high-speed rotating air ring experiences intense friction and impact with the air, causing the yarn itself to heat up. When this heated yarn passes through the yarn guide again, it transfers some of the heat to the guiding device.

[0004] Current yarn guiding devices do not have independent temperature monitoring devices; they simply install temperature measuring modules in certain areas. This results in the inability to monitor the internal temperature comprehensively, which can easily affect the stability and safety of the yarn guiding device and the yarn itself. Summary of the Invention

[0005] The technical problem that this invention aims to solve is that current yarn guiding devices do not have independent temperature monitoring devices, but simply install temperature measuring modules in local areas. This results in the inability to monitor the internal temperature comprehensively, which can easily affect the stability and safety of the yarn guiding device and the yarn.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a fluid omnidirectional temperature measuring device for a yarn guiding device, comprising a yarn guiding roller body and a lateral connecting component. The lateral connecting component is installed on both sides of the yarn guiding roller body. A plurality of circular through holes for installing the lateral mounting shafts of the yarn guiding roller body are opened inside the lateral connecting component. An external hanging lateral sealing cover is threadedly fitted at the outer opening position of the circular through hole. An external series copper pipe is installed on the outer surface of the external hanging lateral sealing cover. An electrically controlled regulating valve is installed inside the external series copper pipe. An electrically controlled fluid regulating device is fixedly installed at both ends of the yarn guiding roller body. A temperature control sensor controller for controlling the electrically controlled fluid regulating device is fixedly installed on the inner wall of the working end of the yarn guiding roller body.

[0007] A sealing flange for connecting an external lateral sealing cover is fixedly assembled on the outer side of the lateral connector at the opening position of the circular through hole. The external lateral sealing cover is fixedly assembled by locking bolts on the sealing flange, and the external lateral sealing cover is fixedly assembled with the lateral connector by locking bolts on the sealing flange.

[0008] An internal fixing frame is fixedly assembled on the inner wall of both ends of the yarn guide roller body, and a side guide groove is opened on the outer wall of the side mounting shaft at one end of the yarn guide roller body.

[0009] The electronically controlled fluid control device includes a lateral support rod fixed in an internal fixed frame, a centrifugal drive blade axially fixed to the extended end of the lateral support rod, and an external closed cover plate fixed to the outside of the centrifugal drive blade.

[0010] The externally mounted lateral sealing cover is fixedly fitted with an externally threaded guide tube for installing an externally connected series copper tube. The externally connected series copper tube is fixedly connected to the externally threaded guide tube through internally threaded locking sleeves on both sides.

[0011] The yarn guide roller, the external side sealing cover, the external series copper pipe and the electronically controlled regulating valve are all filled with a heat-conducting medium, which is either a heat-conducting liquid or air.

[0012] The external series copper tubes are all equipped with built-in temperature control sensors near the assembly end of the external threaded guide tube.

[0013] The electrically controlled fluid control device at one end of the yarn guide roller is equipped with centrifugal drive blades, while the electrically controlled fluid control device at the other end of the yarn guide roller is not equipped with centrifugal drive blades.

[0014] The centrifugal drive blade adopts a two-section structure design, and the size of the end of the centrifugal drive blade near the lateral support rod extension is smaller than the size of the end near the external closed cover plate.

[0015] Pressure control modules are fixedly mounted on both sides of the external closed cover.

[0016] The beneficial effects of this invention are:

[0017] (1) The fluid omnidirectional temperature measuring device for the yarn guiding device of the present invention sets an external lateral sealing cover on the outside of the connection end of the yarn guiding roller and the lateral connecting part, and uses an external series copper pipe with an internally installed electric control regulating valve to connect adjacent external lateral sealing covers, thereby forming a series flow channel between the yarn guiding rollers, thereby enhancing the flow guiding effect and enhancing the temperature measuring efficiency.

[0018] (2) By rotating the yarn guide roller itself, the electronically controlled fluid control device is rotated synchronously, thereby generating power for the internal fluid, which is discharged from one side and drawn in from the other side, forming a moving fluid, thereby rapidly conducting the heat inside the yarn guide roller and improving the temperature measurement accuracy.

[0019] (3) Install the temperature control sensor controller inside the yarn guide roller and at the lateral connection point. It can accurately monitor the temperature at different positions of the yarn guide roller and make the temperature monitoring range and control method more intelligent by automatically controlling the opening and closing of the electronic fluid control device.

[0020] (4) An electric control regulating valve is installed inside the external series copper tube, and a built-in temperature control sensor is installed at the connection end on both sides. The series state can be intelligently switched according to different yarn guide roller temperatures, so as to reduce the mutual influence and improve the intelligent fluid control method.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0028] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] Figure 1 , Figure 2 , Figure 3 and Figure 4The illustrated fluid omnidirectional temperature measuring device for a yarn guiding device includes a yarn guiding roller body 1 and a lateral connecting member 2. The lateral connecting member 2 is installed on both sides of the yarn guiding roller body 1. The lateral connecting member 2 has four circular through holes for installing the lateral mounting shafts of the yarn guiding roller body 1. An external lateral sealing cover 3 is threaded onto the outer opening of the circular through holes. An external series copper pipe 4 is installed on the outer surface of the external lateral sealing cover 3. An electrically controlled regulating valve 5 is installed inside the external series copper pipe 4. Electrically controlled fluid control devices 6 are fixedly installed at both ends of the yarn guiding roller body 1. A temperature control sensor controller 7 for controlling the electrically controlled fluid control device 6 is fixedly installed on the inner wall of the working end of the yarn guiding roller body 1.

[0030] Working principle: During operation, the yarn guide roller 1 generates heat. The temperature control sensor 7 located inside the yarn guide roller 1 monitors the internal temperature changes in real time. When the temperature exceeds the set maximum reasonable range, the temperature control sensor 7 drives the electronically controlled fluid control device 6 to open the openings on both sides of the yarn guide roller 1. As the yarn guide roller 1 rotates, the fluid is drawn in from one side and discharged from the other end, guided into the external series copper pipe 4 on the outer side of the externally attached side-sealed cover 3. The internal fluid is then introduced into the adjacent or distant externally attached side-sealed cover 3 through the electronically controlled regulating valve 5. One end of the external series copper pipe 4 leads out, and the other end leads in. Using the temperature sensing device located at the series end, the fluid speed is calculated based on the rotation speed, and the temperature changes are determined based on the temperature changes, thus accurately measuring the temperature.

[0031] To facilitate external closure and sealing, a sealing flange 8 for connecting an externally mounted lateral sealing cover 3 is fixedly installed on the outer side of the lateral connector 2 at the opening position outside the circular through hole. The externally mounted lateral sealing cover 3 is fixedly assembled by locking bolts on the sealing flange 8 and is fixedly assembled with the lateral connector 2 by locking bolts on the sealing flange 8.

[0032] To facilitate internal installation and guidance, internal fixing frames 9 are fixedly mounted on the inner walls of both ends of the yarn guide roller body 1, and a side guide groove 10 is provided on the outer wall of the side mounting shaft at one end of the yarn guide roller body 1.

[0033] To facilitate internal electronic control adjustment, the electronically controlled fluid control device 6 includes a lateral support rod 61 fixed within the internal fixed frame 9, a centrifugal drive blade 62 axially fixed to the extended end of the lateral support rod 61, and an external closed cover plate 63 fixed to the outside of the centrifugal drive blade 62.

[0034] The centrifugal drive blade 62 and the outer closing cover plate 63 are integrated into one structure. The outer side of the centrifugal drive blade 62 is inserted into the side guide groove 10, thereby ensuring stability and lateral sealing.

[0035] The extended end of the lateral strut 61 is axially inserted into the central shaft of the centrifugal drive blade 62 to be fixedly assembled with the centrifugal drive blade 62 and the outer closing cover plate 63.

[0036] To facilitate threaded assembly and connection, an externally threaded guide pipe 31 for installing an externally connected series copper pipe 4 is fixedly mounted on the outer side of the externally attached side sealing cover 3. The externally connected series copper pipe 4 is fixedly connected to the externally threaded guide pipe 31 through the internally threaded locking sleeves 41 on both sides.

[0037] To enhance the heat conduction effect, the yarn guide roller 1, the external side sealing cover 3, the external series copper pipe 4, and the electrically controlled regulating valve 5 are all filled with a heat-conducting medium, which is either a heat-conducting liquid or air.

[0038] In order to measure the temperature of the yarn guide roller 1 at the adjacent ends, the internal end of the external series copper tube 4, near the assembly end of the external threaded guide tube 31, is fixedly equipped with a built-in temperature control sensor 42.

[0039] By installing the built-in temperature control sensor 42 near the external threaded guide pipe 31, the internal temperature of the yarn guide roller 1 at different positions can be accurately monitored, thereby controlling the communication status between the yarn guide rollers 1. Based on the temperature and speed of the fluid at the outlet, the temperature inside the yarn guide roller 1 at different positions in the initial stage can be determined. As the flow process continues, the temperature inside the yarn guide roller 1 will reach a fixed value. Then, the built-in temperature control sensor 42 will automatically control the rotation of the electronically controlled regulating valve 5 to guide the fluid that is close to it to another position of the externally attached side-sealed cover 3, thereby ensuring the consistency of the temperature measurement effect.

[0040] To ensure that the yarn is exported from one side and introduced from the other side, the electrically controlled fluid control device 6 at one end of the yarn guide roller 1 is equipped with centrifugal drive blades 62, while the electrically controlled fluid control device 6 at the other end of the yarn guide roller 1 is not equipped with centrifugal drive blades 62.

[0041] The electrically controlled fluid control device 6 of the yarn guide roller 1 section has centrifugal drive blades 62. When the yarn guide roller 1 rotates, the centrifugal drive blades 62 rotate synchronously, which will draw the fluid on the other side into the yarn guide roller 1 and then guide the fluid on the same side into the external series copper pipe 4. The fluid is guided into the fluid inlet end of the adjacent yarn guide roller 1 through the external series copper pipe 4, thereby forming a fluid circulation channel. Fluids with similar temperatures are guided to the fluid side of the yarn guide roller 1 with similar temperatures. At the same time, it can also be used in conjunction with the external series copper pipe 4 for auxiliary heat dissipation.

[0042] To improve the centrifugal drive effect, the centrifugal drive blade 62 adopts a two-section structure design, and the size of the end of the centrifugal drive blade 62 near the lateral support rod 61 is smaller than the size of the end near the outer closed cover plate 63.

[0043] The size of the centrifugal drive blade 62 gradually increases from the inside to the outside. After the outer closed cover plate 63 extends outward, it can enhance the liquid guiding effect and reduce the internal flow resistance when rotating.

[0044] To facilitate automatic control of the stroke, pressure control modules 64 are fixedly mounted on both sides of the external closing cover 63.

[0045] The lateral support rod 61 extends and retracts, thereby causing the outer closing cover plate 63 to move horizontally outside the opening on the lateral assembly shaft of the yarn guide roller body 1. The pressure control module 64 on both sides of the outer closing cover plate 63 can monitor the inner and outer squeezing pressure, thereby automatically controlling the extension and retraction and opening and closing of the lateral support rod 61 to avoid excessive extension and retraction.

[0046] I. Working Principle

[0047] This device is based on the core logic of "fluid heat conduction + intelligent dynamic control". By constructing a series flow channel and using the self-power of the yarn guide roller to drive fluid circulation, combined with multi-point temperature monitoring and automatic control, it achieves omnidirectional and accurate temperature measurement of the yarn guide device. The specific principle can be broken down into the following 4 points:

[0048] 1. Serial flow channel construction: ensuring fluid flow throughout the entire process.

[0049] An externally mounted lateral sealing cover 3 is installed on the outside of the connection end between the yarn guide roller 1 and the lateral connecting part 2. An externally mounted series copper pipe 4, with an internally installed electrically controlled regulating valve 5, connects adjacent covers. The externally mounted series copper pipe 4 is fixedly connected to the cover via a threaded fit of an internally threaded locking sleeve 41 and an externally threaded guide pipe 31. This ultimately forms a closed series flow channel consisting of multiple yarn guide rollers 1, the externally mounted lateral sealing cover 3, and the externally mounted series copper pipe 4. The flow channel is filled with a heat-conducting medium (heat-conducting liquid or air), which can conduct localized heat from a single yarn guide roller to the entire flow channel, avoiding "localized temperature measurement blind spots" and laying the foundation for omnidirectional temperature measurement.

[0050] 2. Fluid power source: Relying on the rotation of the yarn guide roller itself.

[0051] The electrically controlled fluid regulation device 6 installed at both ends of the yarn guide roller 1 is the core power source for fluid circulation, and its power comes directly from the rotation of the yarn guide roller:

[0052] Device structure: It consists of lateral support rods 61 fixed on the internal fixed frame 9, centrifugal drive blades 62 assembled axially, and external closed cover plate 63;

[0053] Power logic: When the yarn guide roller 1 is running, it synchronously drives the centrifugal drive blade 62 to rotate (the size of the blade near the end is smaller than the outer size, which can enhance the flow guiding efficiency); and the control device at only one end of the yarn guide roller 1 is equipped with the centrifugal drive blade 62, while the other end has no blade - forming a unidirectional fluid power of "drawing in on one side and discharging on the other side", driving the heat transfer medium to continuously circulate in the series flow channel, and quickly transferring the heat inside the yarn guide roller.

[0054] 3. Multi-point temperature monitoring: Dual sensors achieve omnidirectional coverage

[0055] The device achieves full-range temperature capture of the yarn guide roller body through a combination of built-in main monitoring and series-connected auxiliary monitoring.

[0056] Main monitoring: The temperature control sensor controller 7 on the inner wall of the working end of the yarn guide roller 1 directly monitors the temperature of the core working area of ​​the yarn guide roller and is the "core signal source" that triggers the control action;

[0057] Auxiliary monitoring: The built-in temperature control sensor 42, located near the end of the externally threaded guide tube 31, monitors the temperature of the heat-conducting medium flowing through the series flow channel. Combined with the fluid flow rate (calculated from the rotation speed of the guide roller), the temperature difference of different guide rollers can be calculated, avoiding the measurement deviation of a single sensor.

[0058] 4. Intelligent dynamic control: Switching flow channel and power status as needed.

[0059] The device achieves coordinated control of "temperature-flow channel-power" through electronic control components, improving temperature measurement accuracy and equipment adaptability.

[0060] Power regulation: The temperature control sensor controller 7 monitors the temperature in real time. When the temperature exceeds the set threshold, it automatically starts the electronically controlled fluid regulation device 6 (by controlling the extension and retraction of the lateral support rod to adjust the closing state of the blade and the cover plate) to start fluid circulation; it shuts off when the temperature drops to reduce ineffective energy consumption.

[0061] Flow channel control: The electronically controlled regulating valve 5 inside the external series copper pipe 4 can switch the flow channel connection state as needed based on the monitoring data of the built-in temperature control sensor 42. If the temperature difference between adjacent yarn guide rollers is too large, the corresponding regulating valve can be closed to avoid "high temperature fluid interfering with low temperature roller temperature measurement" and reduce the mutual influence between rollers.

[0062] II. Work Process

[0063] Based on the above principles, the complete working process of the device can be divided into 8 steps, realizing a closed-loop operation of "start-up-monitoring-control-temperature measurement-feedback":

[0064] Step 1: Device initialization and yarn guide start-up

[0065] After the yarn guiding device is started, the yarn guiding roller 1 starts to rotate at high speed, which synchronously drives the internal fixed frame 9 and the electronically controlled fluid control device 6 to rotate with the roller. At this time, the electronically controlled fluid control device 6 is in the "standby closed" state (the external closed cover plate 63 seals the yarn guiding roller port), and the heat transfer medium in the series flow channel does not flow temporarily.

[0066] Step 2: Initial Temperature Monitoring

[0067] The yarn guide roller 1 generates heat due to friction (yarn-yarn guide, bearing friction) and "air impact of the air ring". The temperature control sensor 7 on its inner wall collects the temperature of the core area in real time and compares it with the preset "reasonable temperature range" (such as setting a threshold according to the yarn material and operating speed).

[0068] Step 3: Threshold Triggering and Power Start

[0069] When the temperature control sensor 7 detects that the temperature exceeds the threshold, it immediately sends a start signal to the electronically controlled fluid control device 6:

[0070] The lateral support rod 61 is telescopically adjusted, causing the outer closed cover plate 63 to move outward and open the port of the yarn guide roller 1;

[0071] The centrifugal drive blades 62, which rotate with the yarn guide roller, start working. Utilizing the power difference of the "single-sided blades", the heat transfer medium is drawn in from the bladeless end and discharged from the bladed end to the externally attached lateral sealing cover 3, thus initiating fluid circulation.

[0072] Step 4: Circulation of heat transfer medium and heat transfer

[0073] The heat transfer medium (heat transfer fluid / air) circulates in a series flow path under centrifugal drive: "yarn guide roller 1 → external side-sealed cover 3 → external series copper pipe 4 → adjacent yarn guide roller 1".

[0074] When it flows through the high-temperature guide roller, it absorbs the heat inside the roller;

[0075] When flowing through a low-temperature zone or an external copper tube, heat is transferred to the entire flow channel, causing the temperature of the medium in the flow channel to gradually match the temperature of the entire guide roller.

[0076] Step 5: Multi-point temperature data acquisition

[0077] During fluid circulation, temperature data is collected simultaneously by two sensors:

[0078] The temperature control sensor controller 7 continuously records the real-time temperature changes in the core area of ​​the yarn guide roller;

[0079] The built-in temperature sensor 42 collects the temperature of the medium flowing through the series copper tubes and feeds the data back to the control system. Combined with the rotation speed of the guide roller (to estimate the fluid flow rate), the temperature difference of different guide rollers is calculated (e.g., if the medium temperature of roller A is 28℃ and roller B is 32℃, it can be determined that roller B is locally overheated).

[0080] Step 6: Adapting the flow path of the electronically controlled regulating valve

[0081] The control system adjusts the electrically controlled regulating valve 5 inside the external series copper pipe 4 based on the temperature difference data from the built-in temperature sensor 42.

[0082] If the temperature difference between adjacent yarn guide rollers is small (≤3℃), keep the regulating valve fully open to enhance the flow channel and improve the omnidirectional temperature measurement efficiency;

[0083] If the temperature difference is large (>3℃), close the regulating valve of the corresponding area to isolate the flow channels of the high-temperature roller and the low-temperature roller, so as to avoid the high-temperature medium from interfering with the temperature measurement of the low-temperature roller and ensure that the temperature measurement data of each roller is independent and accurate.

[0084] Step 7: Pressure and Stroke Safety Control

[0085] The pressure control modules 64 on both sides of the external closed cover 63 monitor the compressive pressure on the inside and outside of the cover in real time.

[0086] When the lateral strut 61 extends or retracts excessively (such as when the cover plate and the roller port are squeezed too tightly), the pressure module triggers a signal to control the strut to stop extending or retracting, thus avoiding mechanical wear.

[0087] If the pressure of the medium in the flow channel is abnormal (such as the pressure increase caused by the thermal expansion of the heat transfer fluid), the pressure module will also activate the regulating valve to release pressure and ensure the safety of the flow channel.

[0088] Step 8: Continuous monitoring and dynamic adjustment

[0089] The device is constantly in a dynamic cycle of "monitoring-control-feedback":

[0090] If the temperature of the yarn guide roller drops back to a reasonable range, the temperature control sensor controller 7 sends a signal to shut down the electronically controlled fluid control device 6, and the external closed cover 63 resets and seals, reducing energy consumption.

[0091] If the temperature exceeds the threshold again, repeat steps 3-7 to maintain the accuracy of omnidirectional temperature measurement and ensure the stability of the yarn guide device and yarn.
