Description

Technical Field

[0001] This utility model relates to the field of fabric processing, specifically to a fabric temperature measuring device and fabric processing equipment for a drying room. Background Technology

[0002] In the heat treatment process of the textile industry, fabrics are heat-set using multiple high-temperature drying chambers. For example, in a setting machine, the temperature inside the high-temperature drying chamber is typically 180℃-250℃. Accurate measurement of the fabric surface temperature is crucial to ensuring the setting effect and product quality.

[0003] Currently, the industry commonly uses infrared thermometers to measure the temperature of fabrics inside high-temperature drying chambers. These devices mainly consist of a hollow tube, an infrared sensor, and a transparent lens. The hollow tube penetrates the drying chamber wall, the infrared sensor is installed at its protruding end, and the transparent lens is fixed inside the hollow tube and located in front of the sensor. The infrared sensor achieves non-contact measurement of the fabric surface temperature through the infrared radiation transmitted through the lens. For example, patent application number 201921241729.2, entitled "Temperature Measurement Device for Fabrics in Stenter Drying Chambers of Tensioners," uses this structure. However, the complex environment of high temperature, oil stains, and fiber debris leads to the following drawbacks in this type of infrared thermometer:

[0004] (1) Deterioration of light transmittance of lens: When the lens is exposed to high temperature drying room for a long time, the surface is easily contaminated by high temperature oils, fiber dust and other pollutants volatilized from the fabric. In addition, continuous high temperature baking will cause the lens material (such as quartz glass or sapphire) to sand or thermal stress deformation, resulting in a decrease in light transmittance.

[0005] (2) Inaccurate measurement results: As the light transmittance of the lens decreases, the proportion of the lens's own thermal radiation in the radiation energy received by the infrared sensor increases, which ultimately leads to the detection signal reflecting the lens temperature rather than the actual temperature of the fabric, seriously affecting the accuracy of process control.

[0006] (3) High maintenance costs: The light-transmitting lens needs to be made of special materials with high temperature resistance and high light transmittance (such as coated optical glass), which has a high unit price. Moreover, replacement requires stopping the machine to disassemble the hollow tube assembly, resulting in a decrease in equipment utilization and a surge in maintenance costs.

[0007] Although existing technologies attempt to isolate the effects of high-temperature environments on sensors through hollow tube structures, their inherent design flaw of relying on transparent lenses makes it difficult to fundamentally solve the aforementioned problems in fabric temperature measurement within setting machines. Therefore, there is an urgent need to develop a device that does not require transparent lenses, is low-cost, and can accurately and stably measure fabric temperature directly in high-temperature environments. Summary of the Invention

[0008] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a fabric temperature measuring device for drying room, which can achieve accurate and stable measurement of fabric temperature in high temperature environment at a low cost.

[0009] To solve the above-mentioned technical problems, the technical solution of this utility model is: a fabric temperature measuring device for a drying room, comprising:

[0010] A carrier for mounting on the wall of the drying chamber of the setting machine, one end of which extends close to the fabric inside the drying chamber;

[0011] A temperature measuring assembly includes a temperature measuring device and a heat-conducting block. The heat-conducting block is installed at the end of the carrier near the fabric, with the surface near the fabric serving as the temperature-sensing surface. The temperature measuring device is used to detect the temperature of the heat-conducting block.

[0012] The heat insulation part is disposed between the carrier and the heat-conducting block, and does not cover the temperature-sensing surface.

[0013] Furthermore, in order to minimize the impact of the temperature inside the drying chamber on the fabric temperature measurement results, the heat insulation part extends beyond the temperature sensing surface in the direction towards the fabric, forming a temperature sensing groove with an opening facing the fabric surface.

[0014] Furthermore, the carrier does not extend beyond the heat insulation portion in the direction of the fabric.

[0015] Furthermore, the distance between the end face of the heat insulation part facing the fabric and the fabric is 1-8 mm.

[0016] Furthermore, the distance between the temperature-sensing surface and the fabric is 8-50mm.

[0017] Further, a specific structure of a heat insulation part is provided, wherein the heat insulation part is a heat insulation sleeve, one end of the heat insulation sleeve is a blind end, the other end is an opening, the blind end is connected to the carrier, and the heat-conducting block is embedded in the opening.

[0018] Furthermore, the thermal sensor is embedded in the center of the heat-conducting block, and the cross-sectional area of ​​the heat-conducting block is 5-20 times the cross-sectional area of ​​the thermal sensor.

[0019] Furthermore, the temperature measuring device is an infrared sensor, the carrier is a cover, and the infrared sensor is installed inside the cover to achieve non-contact temperature measurement of the heat-conducting block;

[0020] Alternatively, the temperature measuring device may be a thermistor, which is embedded in or in contact with the heat-conducting block to achieve contact temperature measurement of the heat-conducting block.

[0021] Furthermore, when the temperature measuring device is a thermistor, the temperature measuring device is a thermistor embedded in the center of the heat-conducting block, and the cross-sectional area of ​​the heat-conducting block is 5-20 times the cross-sectional area of ​​the thermistor.

[0022] Furthermore, in order to facilitate the installation of the carrier on the drying chamber wall, the outer surface of the carrier is fitted with a fixing flange for mounting it to the drying chamber wall.

[0023] Furthermore, the heat-conducting block is made of aluminum or copper.

[0024] Furthermore, the carrier is a cover.

[0025] This utility model also relates to a fabric processing device, including a fabric temperature measuring device for a drying room.

[0026] After adopting the above technical solution, the heat insulation part can play a role in isolation, preventing the high temperature of the carrier and the drying chamber from affecting the heat-conducting block. This ensures that the temperature of the heat-conducting block is only affected by the fabric, and the temperature measuring device measures the fabric temperature by measuring the temperature of the heat-conducting block. Compared to the indirect method of traditional infrared thermometry that relies on lens transmission, the device in this invention captures the fabric surface temperature through the efficient heat conduction of the heat-conducting block, avoiding inaccurate measurement results due to medium contamination or lens deterioration. This prevents temperature measurement errors caused by pollution such as oil fumes in the drying chamber, resulting in more accurate and stable measurement results. Furthermore, both the temperature measuring device and the heat-conducting block are common industrial components, with costs far lower than high-transmittance special lenses and precision infrared sensors. Moreover, no complex optical calibration system is required, thus significantly reducing the overall cost of the device and lowering the overall operation and maintenance costs.

Detailed Implementation

[0033] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0034] Example 1

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a fabric temperature measuring device for a drying room includes:

[0036] The carrier 1 is used to be installed on the wall of the drying chamber of the setting machine, and one end of it is used to extend close to the fabric 6 inside the drying chamber;

[0037] The temperature measuring component includes a temperature measuring device 2 and a heat-conducting block 3. The heat-conducting block 3 is installed at the end of the carrier 1 near the fabric 6, and the surface near the fabric 6 is the temperature sensing surface 31. The temperature measuring device 2 is used to detect the temperature of the heat-conducting block 3.

[0038] The heat insulation part 4 is disposed between the carrier and the heat-conducting block 3, and does not cover the temperature-sensing surface 31.

[0039] Specifically, the heat insulation part 4 acts as an insulator, preventing the high temperature of the carrier 1 and the drying chamber from affecting the heat-conducting block 3. This ensures that the temperature of the heat-conducting block 3 is only affected by the fabric 6. The temperature measuring device 2 measures the temperature of the fabric 6 by measuring the temperature of the heat-conducting block 3. Compared to the indirect method of traditional infrared temperature measurement that relies on lens transmission, the device in this embodiment directly captures the surface temperature of the fabric 6 through the efficient heat conduction of the heat-conducting block 3. This avoids inaccurate measurement results due to medium contamination or lens deterioration, thus preventing temperature measurement errors caused by pollution such as oil fumes in the drying chamber. Therefore, the measurement results are more accurate and stable.

[0040] Furthermore, both the temperature measuring device 2 and the heat-conducting block 3 are common industrial components, with costs far lower than high-transmittance special lenses and precision infrared sensors, and no complex optical calibration system is required. Therefore, the overall cost of the device in this embodiment is significantly reduced, and the overall operation and maintenance costs are lowered.

[0041] In this embodiment, preferably, as follows: Figures 1 to 5As shown, the heat insulation part 4 extends beyond the temperature sensing surface 31 towards the fabric 6, forming a temperature sensing groove 7 with an opening facing the surface of the fabric 6. The distance between the temperature sensing surface 31 and the fabric 6 can be, but is not limited to, 8-50 mm; the distance between the end face of the heat insulation part 4 facing the fabric 6 and the fabric 6 can be, but is not limited to, 1-8 mm.

[0042] Thus, the portion of the heat insulation part 4 extending beyond the temperature-sensing surface 31 towards the fabric 6 forms a "protective eaves" structure. This reduces the direct impact of the high-temperature airflow inside the drying chamber on the heat-conducting block 31 and prevents contaminants from accumulating on the temperature-sensing surface 31. Therefore, this embodiment can effectively isolate the heat-conducting block 3 from the influence and interference of the high temperature inside the drying chamber, ensuring that the heat-conducting block 3 is only affected by the temperature field of the fabric 6 itself during the high-speed operation of the fabric 6, thereby allowing for more accurate measurement of the fabric 6 temperature.

[0043] In this embodiment, the carrier 1 preferably does not extend beyond the heat insulation part 4 in the direction of the fabric 6, and there are various ways to install the heat insulation part 4.

[0044] The first type, such as Figure 1 and Figure 2 As shown, the heat insulation part extends beyond the carrier 1 in the direction of the fabric 6. The heat insulation part 4 is a heat insulation sleeve. One end of the heat insulation sleeve is a blind end, and the other end is an open end. The blind end is connected to the carrier 1. It can be threaded to the carrier 1 or inserted into the carrier 1 with an interference fit. The heat conducting block 3 is embedded in the open end.

[0045] The second type, such as Figure 3 , Figure 4 and Figure 5 As shown, the heat insulation part 4 is flush with the carrier 1 in the direction toward the fabric 6, the heat insulation part 4 is embedded in the carrier 1, and the heat-conducting block 3 is embedded in the heat insulation part 4.

[0046] In this embodiment, the support 1 can be a cover, a frame, or other structures. The heat-conducting block 3 can be made of aluminum or copper. The heat insulation part 4 can be made of silicone or the like.

[0047] In this embodiment, the temperature measuring device 2 can be of various types.

[0048] The first method uses contact temperature measurement. For example... Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the temperature measuring device 2 is a thermistor 2b, which is embedded in or in contact with the heat-conducting block 3, for contact-type temperature measurement of the heat-conducting block 3. Thermistor 2b can be a thermocouple, thermistor, thermistor semiconductor, platinum resistance temperature sensor (such as PT100, PT1000, etc.), digital temperature sensor, etc. When thermistor 2b is a thermistor, preferably, the thermistor is embedded in the center of the heat-conducting block 3, and the cross-sectional area of ​​the heat-conducting block 3 is 5-20 times the cross-sectional area of ​​the thermistor.

[0049] The second method uses non-contact temperature measurement. For example... Figure 5 As shown, the temperature measuring device 2 is an infrared sensor 2a, and the carrier 1 is a cover. The infrared sensor 2a is installed inside the cover and is used to perform non-contact temperature measurement on the heat-conducting block 3. The cover can protect the infrared sensor 2a and ensure its long-term stable and accurate operation.

[0050] Example 2

[0051] like Figures 1 to 4 As shown, the main difference between this embodiment and Embodiment 1 is that the outer surface of the carrier 1 is equipped with a fixing flange 5 for mounting it to the wall of the drying room.

[0052] In this way, the carrier 1 can be installed on the wall of the drying room by fixing the flange, which reduces the installation difficulty.

[0053] Among them, the carrier 1 can extend into the drying room from the top of the drying room, the circumferential side wall, etc.

[0054] Example 3

[0055] A fabric processing device includes a fabric temperature measuring device for a drying room, as described in Embodiment 1 or Embodiment 2. The fabric processing device can be a setting machine, a baking machine, a dryer, etc.

[0056] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
