Abstract
Description
Technical Field
[0001] This application relates to the field of light-reflecting equipment, and in particular to a light-reflecting equipment and its temperature control method. Background Technology
[0002] Existing slurry machines generate heat during operation due to friction between materials and media. To prevent heat accumulation from affecting the processing quality of materials, the heat needs to be dissipated in a timely manner.
[0003] Currently, most heat exchangers achieve heat dissipation by installing fans on the chassis to force the hot air out of the chassis. This method has very limited heat dissipation effect and cannot control the temperature, resulting in fluctuating temperatures inside the heat exchanger, which greatly affects the quality of material processing.
[0004] For example, aluminum alloys have a relatively high coefficient of thermal expansion (approximately 23.1 × 10⁻⁻⁻⁴). 6 The dimensional tolerance of aluminum alloy workpieces (such as hydraulic valve cores and mold cavities) after polishing is usually within ±5μm. If the temperature inside the polishing barrel is too high, it will cause thermal expansion of the aluminum alloy workpiece, resulting in the actual size after processing deviating from the design value. By the time of assembly, the workpiece has cooled down and its volume has shrunk compared to the workpiece that has expanded thermally inside the polishing barrel. Therefore, the problem of "excessive gap" will occur during assembly. Thus, temperature fluctuations will damage the dimensional accuracy of the workpiece.
[0005] On the other hand, excessively high temperatures can affect the uniformity of the polished surface quality, making it impossible to guarantee consistent quality across batches. The core of polishing is "micro-grinding," and the coefficient of friction between the grinding media and the workpiece changes with temperature: as temperature rises, the media (such as resin beads) softens slightly, reducing the coefficient of friction and decreasing grinding efficiency; as temperature falls, the media hardens, increasing the coefficient of friction and potentially leading to over-grinding of the workpiece surface. Therefore, fluctuating temperatures within the polishing chamber can cause variations in surface roughness within the same batch of workpieces (some with Ra 0.2μm, others with Ra 0.8μm). This uneven surface roughness is particularly problematic for workpieces requiring subsequent anodizing, as it can result in inconsistent oxide film thickness and noticeable color differences. Summary of the Invention
[0006] To improve the temperature control quality of the luminescence equipment, this application provides a luminescence equipment and its temperature control method.
[0007] In one aspect of this disclosure, a light-guiding device is provided, including a chassis and a light-guiding barrel disposed inside the chassis. The barrel wall of the light-guiding barrel is hollowed out. A refrigeration unit is disposed outside the chassis. The refrigeration unit includes an air supply pipe. The air outlet of the air supply pipe is connected to a distribution pipe. The distribution pipe is located inside the chassis. An air outlet is provided on the pipe wall of the distribution pipe. The air supply pipe is connected to a regulating valve and a drying device. The chassis is equipped with a flow guide fan, which is used to guide the airflow toward the light-blowing barrel. The chassis has an air outlet, and both the air outlet and the air vent are equipped with temperature and humidity detection components and dew point temperature detection components. Temperature detection components are installed at the center and on the wall of the smoothing barrel.
[0008] By adopting the above technical solution, cold air is injected into the polishing barrel by means of a refrigeration unit, and at the same time, real-time monitoring is carried out by temperature and humidity detection components and dew point temperature detection components to achieve stable temperature control of the polishing barrel, eliminate local heat accumulation, and avoid thermal expansion and contraction deformation and high-temperature oxidation of aluminum alloy parts caused by temperature fluctuations.
[0009] Preferably, the drying apparatus includes: Molecular sieve desiccant is used to dry cold air in air ducts; A flow guiding component is used to guide the cold air in the air duct through the molecular sieve desiccant. Heating components are used to heat the molecular sieve desiccant, thereby regenerating it.
[0010] By adopting the above technical solution, on the one hand, a drying device can be introduced to dry the cold air as needed, and on the other hand, the drying device can be not introduced to dry the cold air when not needed, thereby extending the service life of the drying device and reducing the energy consumption of the drying device.
[0011] Preferably, the slurry equipment also includes a slurry barrel rotation speed and load detection component for detecting the slurry barrel rotation speed and material filling amount, and the barrel wall of the slurry barrel is also provided with a condensation detection component.

[0013] In another aspect of this disclosure, a temperature control method for a light-guiding device is provided, comprising: The temperature, humidity, and dew point of the air outlet and vent, as well as the temperature of the center and wall of the slicker tank, are obtained. Determine whether the temperature at the center of the polishing barrel, the temperature difference between the center of the polishing barrel and the barrel wall are within the set range, and whether there is a risk of condensation on the barrel wall; In response to the temperature at the center of the polishing barrel and / or the temperature difference between the center of the polishing barrel and the barrel wall being outside the set range, adjust the airflow at the air outlet and / or the power of the refrigeration unit. In response to the risk of condensation on the barrel wall, the cold air in the air supply duct is dried.
[0014] By adopting the above technical solutions, the temperature inside the polishing drum and the working area are controlled within a suitable set range, and local heat accumulation is eliminated. This avoids thermal expansion and contraction deformation and high-temperature oxidation of aluminum alloy parts caused by temperature fluctuations. Furthermore, by predicting in advance whether condensation will occur in the polishing drum and adjusting the humidity of the cold air accordingly, condensation is eliminated at the outset while ensuring stable temperature control of the polishing drum. This achieves zero condensation risk and effectively avoids the problem of surface quality defects, decreased process stability, or even workpiece scrap caused by condensation contacting aluminum alloy parts.
[0015] Preferably, the center temperature of the polishing barrel is set within the range of 20℃-25℃; The temperature difference between the center of the polishing barrel and the barrel wall is set to be no more than 2℃. When the temperature difference between the barrel wall and the dew point temperature at the air outlet is no more than 2°C, there is a risk of condensation on the barrel wall.
[0016] Preferably, in response to the temperature difference between the center of the polishing barrel and the barrel wall exceeding a set range, the guide fan is activated to guide the airflow toward the polishing barrel.
[0017] By adopting the above technical solution, the ability of cold air to penetrate the gaps between materials is enhanced, and the air inside the barrel is forcibly stirred and cleared, ensuring that the temperature inside the barrel is uniform and without dead corners, thereby quickly eliminating local heat accumulation.
[0018] In another aspect of this disclosure, a temperature control method for a light-guiding device is provided, comprising: The temperature, humidity, and dew point of the air outlet and vent, as well as the temperature of the center and wall of the slicker tank, are obtained. Determine whether the temperature at the center of the polishing barrel, the temperature difference between the center of the polishing barrel and the barrel wall are within the set range, and whether there is a risk of condensation on the barrel wall; In response to the temperature at the center of the polishing barrel and / or the temperature difference between the center of the polishing barrel and the barrel wall being outside the set range, adjust the airflow at the air outlet and / or the power of the refrigeration unit. In response to the risk of condensation on the barrel wall, the cold air in the air duct is dried; In response to the risk of condensation on the barrel wall, the control flow-guiding component guides a small amount of cold air in the air supply pipe to flow through the molecular sieve desiccant to prevent the molecular sieve desiccant from becoming damp and caking.
[0019] By adopting the above technical solutions, the temperature inside the polishing drum and the working area are controlled within a suitable set range, and local heat accumulation is eliminated. This avoids thermal expansion and contraction deformation and high-temperature oxidation of aluminum alloy parts caused by temperature fluctuations. Furthermore, by predicting in advance whether condensation will occur in the polishing drum and adjusting the humidity of the cold air accordingly, condensation is eliminated at the outset while ensuring stable temperature control of the polishing drum. This achieves zero condensation risk and effectively avoids the problem of surface quality defects, decreased process stability, or even workpiece scrap caused by condensation contacting aluminum alloy parts.
[0020] In another aspect of this disclosure, a temperature control method for a light-guiding device is provided, comprising: Acquire the temperature, humidity and dew point of the air outlet and air vent, the temperature of the center and wall of the sprue, the rotation speed and load data of the sprue, and the condensation data of the wall. Determine whether the rotation speed and load of the slicker drum are within the set range; In response to the fact that the speed and load of the slicker drum are not within the set range, adjust the air volume at the air outlet and / or the power of the refrigeration unit; Determine whether the temperature at the center of the polishing barrel, the temperature difference between the center of the polishing barrel and the barrel wall are within the set range, and whether there is a risk of condensation on the barrel wall; In response to the temperature at the center of the polishing barrel and / or the temperature difference between the center of the polishing barrel and the barrel wall being outside the set range, adjust the airflow at the air outlet and / or the power of the refrigeration unit. In response to the risk of condensation on the barrel wall, the cold air in the air supply duct is dried.
[0021] By adopting the above technical solutions, the temperature inside the polishing drum and the working area are controlled within a suitable set range, and local heat accumulation is eliminated. This avoids thermal expansion and contraction deformation and high-temperature oxidation of aluminum alloy parts caused by temperature fluctuations. Furthermore, by predicting in advance whether condensation will occur in the polishing drum and adjusting the humidity of the cold air accordingly, condensation is eliminated at the outset while ensuring stable temperature control of the polishing drum. This achieves zero condensation risk and effectively avoids the problem of surface quality defects, decreased process stability, or even workpiece scrap caused by condensation contacting aluminum alloy parts.
[0022] Preferably, the rotation speed of the polishing barrel is set within the range of 100rpm-200rpm, and the load of the polishing barrel is set within the range of 30%≤filling amount≤70%.
[0023] Preferably, in response to the shunting barrel's rotation speed and load exceeding the set range, and the temperature difference between the shunting barrel's center and the barrel wall being within the set range, and the temperature difference approaching the maximum value of the set range, the guide fan is activated and / or the airflow at the outlet is increased and / or the power of the refrigeration unit is increased.
[0024] By adopting the above technical solutions, the air volume and / or power of the refrigeration unit can be increased in advance, or the guide fan can be started to cope with the high load conditions of the polishing equipment, so as to avoid the sudden impact of local heat accumulation on the polishing quality of the workpiece.
[0025] Beneficial technical effects: 1.

[0034] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore detailed descriptions of them will be omitted. Furthermore, the drawings are merely illustrative of this disclosure and are not necessarily drawn to scale.
[0035] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.
[0036] In one aspect of this disclosure, a light-guiding device is provided, such as... Figure 1 and Figure 2As shown, the polishing equipment includes a housing 1 and a polishing barrel 2 disposed inside the housing 1. The barrel wall of the polishing barrel 2 is hollowed out. A refrigeration unit 5 is disposed outside the housing 1. The refrigeration unit 5 includes an air supply pipe 4. The air outlet of the air supply pipe 4 is connected to a distribution pipe 3. The distribution pipe 3 is located inside the housing 1. An air outlet 31 is provided on the pipe wall of the distribution pipe 3. The cold air generated by the refrigeration unit 5 enters the distribution pipe 3 through the air supply pipe 4 and then enters the housing 1 from the air outlet 31, thereby reducing the temperature inside the housing 1 and the polishing barrel 2 and preventing the temperature inside the housing 1 and the polishing barrel 2 from being too high, which would affect the processing quality of materials such as aluminum alloys.
[0037] like Figure 1 and Figure 2 As shown, the air supply pipe 4 is connected to a regulating valve and a drying device 7. The regulating valve is used to regulate the air volume of cold air in the air supply pipe 4, and the drying device 7 is used to dry the cold air, reduce the humidity of the cold air, and prevent condensation from appearing on the barrel wall of the smoothing barrel 2, which would affect the processing quality of materials such as aluminum alloy.
[0038] Preferably, the drying device 7 includes: a molecular sieve desiccant, a flow guiding component, and a heating component. The molecular sieve desiccant is used to dry the cold air in the air duct 4. The advantage of using a molecular sieve desiccant to dry the cold air is that the molecular sieve is renewable, which minimizes the cost of drying the cold air.
[0039] The flow-guiding component is used to guide the cold air in the air duct 4 through the molecular sieve desiccant. For example, if the flow-guiding component is a fan, the fan guides the cold air through the molecular sieve desiccant. Changing the fan speed can change the amount of cold air flowing through the molecular sieve desiccant; if the fan stops, the amount of cold air flowing through the molecular sieve desiccant is minimal. Alternatively, if the flow-guiding component is a valve, increasing the valve opening increases the amount of cold air flowing through the molecular sieve desiccant, and vice versa. The valve opening can be automatically adjusted by electric, hydraulic, or pneumatic means.
[0040] The heating element is used to heat the failed molecular sieve desiccant, thereby regenerating it.
[0041] In this embodiment, the sizing equipment can introduce a drying device 7 to dry the cold air as needed during operation, so as to avoid condensation on the barrel wall of the sizing barrel 2, which would affect the processing quality of materials such as aluminum alloys. When there is no risk of condensation, it is not necessary to introduce the drying device 7 to dry the cold air, thereby reducing the power consumption of the fan and extending the service life of the molecular sieve desiccant.
[0042] It should be noted that when there is no risk of condensation, in order to prevent the molecular sieve desiccant from becoming damp and caking, a small amount of cold air needs to be maintained flowing through the molecular sieve desiccant.
[0043] Furthermore, a guide fan is installed inside the casing 1 to guide the airflow toward the smoothing barrel 2; this increases the penetration of the cold airflow into the smoothing barrel 2, enhances the ability of the cold air to penetrate the gaps between materials, and forcibly stirs the air inside the smoothing barrel 2, ensuring that the temperature inside the barrel is uniform and without dead corners, thereby quickly eliminating local heat accumulation.
[0044] In addition, the chassis 1 is equipped with an air outlet. After the cold air enters the chassis 1 through the air outlet 31, it carries away the heat in the light-reflecting barrel 2. Then the hot air leaves the chassis 1 through the air outlet.
[0045] Both the air outlet and the air vent 31 are equipped with temperature and humidity detection components and dew point temperature detection components, which are used to detect the airflow temperature and humidity and dew point temperature at the air outlet and the air vent 31, respectively. The center and the wall of the smoothing barrel 2 are equipped with temperature detection components, which are used to detect the temperature of the core area and the surface area inside the smoothing barrel 2, respectively. This provides a basis for subsequent judgment on whether the smoothing equipment is working properly, whether there is heat accumulation inside the smoothing barrel 2, and whether there is a risk of condensation on the barrel wall of the smoothing barrel 2.
[0046] For example, if a large temperature difference is detected between the core area and the surface area inside the smoothing barrel 2, it indicates that there is localized heat accumulation inside the smoothing barrel 2, which needs to be eliminated.
[0047] For example, when the surface temperature of the smoothing barrel 2 is detected to be close to the dew point temperature of the air outlet, it indicates that there is a risk of condensation on the barrel wall of the smoothing barrel 2.
[0048] For example, if the operating parameters of the light-guiding equipment remain unchanged (e.g., the speed and load of the light-guiding barrel 2 remain unchanged), and the temperature of the air outlet is detected to be rising while the temperature of the air outlet 31 remains unchanged, it indicates that the air volume entering the casing 1 is abnormally reduced. The staff needs to check whether there are problems such as air leakage in the air supply pipe 4 or blockage of the air outlet of the refrigeration unit 5.
[0049] Of course, if the temperature of the air outlet is detected to be rising and fluctuating, it indicates that there is a risk of air leakage in chassis 1.
[0050] In addition, if the temperature and humidity at the air outlet 31 are detected to be rising, the power of the refrigeration unit 5 needs to be increased and the drying of the cold air needs to be started. If the dew point temperature at the air outlet 31 remains high, it indicates that the dryer has failed.
[0051] Furthermore, the slurry equipment also includes a slurry barrel 2 rotation speed and load detection component, used to detect the slurry barrel 2 rotation speed and material filling amount. Specifically, the slurry barrel 2 load detection component can use a piezoelectric vibration sensor, which is fixed on the bearing seat of the slurry barrel 2. The bearing seat vibrates with the slurry barrel 2 without rotating. The working principle is that the vibration frequency and amplitude of the slurry barrel 2 vary depending on the material filling amount. After the sensor collects the vibration signal, the PLC calculates the real-time filling amount through a preset "vibration frequency - filling amount" calibration curve.
[0052] The speed and load detection components of the polishing barrel 2 can detect the speed and load of the polishing barrel 2, so as to adjust the air volume and power of the refrigeration unit 5 in advance to deal with different working conditions of the polishing equipment, and avoid power waste and sudden local heat accumulation that may affect the polishing quality of the workpiece.
[0053] For example, when the rotation speed and load of the polishing barrel 2 are detected to be high, the temperature rises faster during operation and the risk of local heat accumulation inside the barrel is high. Therefore, the air volume and cooling power can be increased in advance to deal with the risk of a sudden temperature rise in the future, so as to avoid the sudden local heat accumulation affecting the polishing quality of the workpiece.
[0054] For example, when the speed and load of the cooling barrel 2 are detected to be low, the air volume and cooling power can be reduced in advance, so that the refrigeration unit 5 does not need to operate at normal air volume and power, thus avoiding power waste.
[0055] In this embodiment of the disclosure, the barrel wall of the smoothing barrel 2 is also provided with a condensation detection component. As a backup detection element, the condensation detection component can directly detect whether condensation has occurred on the barrel wall of the smoothing barrel 2 when the detection data of the temperature and humidity detection component and the dew point temperature detection component are used to calculate whether there is a risk of condensation failure on the barrel wall. Emergency measures can be taken in time to eliminate condensation.
[0056] For example, under normal circumstances, the processor can calculate whether there is a risk of condensation on the barrel wall by using the surface temperature of the smooth barrel 2 and the dew point temperature of the air outlet. If the temperature and humidity detection component and the dew point temperature detection component malfunction and their detection data is abnormally distorted, the condensation detection component will continue to detect whether condensation occurs on the barrel wall of the smooth barrel 2. Moreover, the detection data of the condensation detection component can be used to verify whether the temperature and humidity detection component and the dew point temperature detection component are working properly. In short, the presence of the temperature and humidity detection component, the dew point temperature detection component, and the condensation detection component can perform "cross-validation of each other's detection data" to calibrate the detection accuracy of the detection components.
[0057] Specifically, when the condensation detection component detects condensation on the wall of the smoothing tank 2, the risk of condensation can be eliminated through one or more of the following operations.
[0058] 1. Extend the operating time of drying device 7 to deeply dry the cold air; 2. Increase the temperature of the cold air to reduce the temperature difference between the cold air and the barrel wall; 3. Increase the speed of the guide fan to accelerate the expulsion of humid air from the tank; 4. If condensation continues, reduce the rotation speed of the shunting equipment to reduce frictional heat generation and prevent the temperature difference from widening further.
[0059] As an example, the temperature detection component can use an industrial-grade PT100 platinum resistance temperature sensor (miniature package). The core area temperature sensor is installed at the center of the axial middle section + radial center of the smoothing barrel 2, directly contacting the material friction core area to collect the most accurate heat generation temperature. The surface area temperature sensor is installed at the axial middle section of the barrel + near the inner wall to collect the temperature of the surface material inside the barrel, calculate the temperature difference with the core area, and thus determine whether there is local heat accumulation.
[0060] Furthermore, both temperature sensors can be customized with stainless steel wear-resistant protective sleeves (2mm wall thickness, HRC55 hardness). One end of the sleeve is closed, while the other end has an opening allowing the sensor probe to protrude 5mm (ensuring contact with the material). A 3mm thick polyurethane buffer layer is welded to the outer wall of the protective sleeve to absorb the impact force of the material / medium and prevent damage to the sensor. The protective sleeve is fixed to a preset position on the inner wall of the container using high-temperature resistant clips to prevent it from falling off during high-speed rotation. Both temperature sensors transmit data via a conductive slip ring or through rechargeable wireless transmission.
[0061] In another aspect of the embodiments of this disclosure, a temperature control method for a light-guiding device is provided, such as... Figure 3 As shown, it includes: S11. Obtain the temperature, humidity and dew point of the air outlet and air outlet 31, and the temperature of the center and wall of the light-reflecting barrel 2; S12. Determine whether the center temperature of the polishing barrel 2, the temperature difference between the center of the polishing barrel 2 and the barrel wall are within the set range, and whether there is a risk of condensation on the barrel wall. As an example, the center temperature of the polishing barrel 2 is set within the range of 20℃-25℃. This temperature range is designed to match the material properties of aluminum alloy, avoiding the risks of thermal deformation and oxidation, while also adapting to the performance of the resin bead polishing medium to ensure polishing efficiency and surface quality. Furthermore, it effectively balances cooling energy consumption and cost control.
[0062] As an example, the temperature difference between the center and the wall of the polishing barrel 2 is set to be no greater than 2℃. When the temperature difference between the center and the wall of the polishing barrel 2 is greater than 2℃, it indicates that there is a risk of local heat accumulation. It is necessary to start the guide fan to enhance the flow of cold air through the polishing barrel 2 and eliminate the heat accumulation. Of course, if the processing precision requirements of the polishing material are high, the temperature difference between the center and the wall of the polishing barrel 2 is set to be no greater than 1℃.
[0063] As an example, when the temperature difference between the wall of the shunting barrel 2 and the dew point temperature at the air outlet is no greater than 2°C, there is a risk of condensation on the barrel wall. At this time, the drying device 7 is activated to reduce the humidity of the cold air to eliminate the risk of condensation. The drying cold air can be stopped once the temperature difference between the wall of the shunting barrel 2 and the dew point temperature at the air outlet is greater than 2°C.
[0064] S13. In response to the temperature of the center of the polishing barrel 2 and / or the temperature difference between the center of the polishing barrel 2 and the barrel wall being outside the set range, adjust the air volume of the air outlet 31 and / or the power of the refrigeration unit 5 to maintain the temperature inside the polishing barrel 2 within a suitable set range, so as to avoid the aluminum alloy parts from thermal expansion and contraction deformation and high temperature oxidation caused by sudden temperature fluctuations. Specifically, when the center temperature of the polishing barrel 2 exceeds the upper limit of the set range, the air volume of the air outlet 31 is first increased, for example, by 10%-30%. After several increases, if the temperature does not decrease, the power of the refrigeration unit 5 is then increased, for example, by increasing the compressor frequency by 5Hz each time. Conversely, when the center temperature of the polishing barrel 2 is below the lower limit of the set range, the air volume of the air outlet 31 is first reduced. If the temperature does not rise, the power of the refrigeration unit 5 is then reduced. This controls the temperature inside the polishing barrel 2 and the working area within a suitable set range, eliminates local heat accumulation, and avoids thermal expansion and contraction deformation and high-temperature oxidation of the aluminum alloy parts caused by sudden temperature fluctuations.
[0065] S14. In response to the risk of condensation on the barrel wall, the cold air in the air duct 4 is dried.
[0066] Once the risk of condensation is eliminated, drying can be stopped. Therefore, in this embodiment, the sizing equipment can introduce the drying device 7 to dry the cold air as needed during operation to prevent condensation from forming on the walls of the sizing tank 2, which could affect the processing quality of materials such as aluminum alloys. When there is no risk of condensation, it is not necessary to introduce the drying device 7 to dry the cold air, thereby reducing fan power consumption and extending the service life of the molecular sieve desiccant. This achieves dynamic control of the power consumption of the refrigeration unit 5 and the drying device 7 during temperature control, resulting in significant energy savings.
[0067] The temperature control method of the polishing equipment in this embodiment determines in advance whether there is a risk of condensation on the barrel wall, and then adjusts the humidity of the cold air accordingly. Under the condition of ensuring stable temperature control of polishing barrel 2, condensation is eliminated in its infancy, achieving zero risk of condensation. This effectively avoids the problem of surface quality defects, decreased process stability, or even workpiece scrap caused by condensation contacting aluminum alloy parts.
[0068] In another aspect of the embodiments of this disclosure, a temperature control method for a light-guiding device is provided, such as... Figure 4 As shown, it includes: S21. Obtain the temperature, humidity and dew point of the air outlet and air outlet 31, and the temperature of the center and wall of the smoothing barrel 2; S22. Determine whether the center temperature of the polishing barrel 2, the temperature difference between the center of the polishing barrel 2 and the barrel wall are within the set range, and whether there is a risk of condensation on the barrel wall. S23. In response to the fact that the center temperature of the polishing barrel 2 and / or the temperature difference between the center of the polishing barrel 2 and the barrel wall is not within the set range, adjust the air volume of the air outlet 31 and / or the power of the refrigeration unit 5. S24. In response to the risk of condensation on the barrel wall, the cold air in the air duct 4 is dried; S25. In response to the risk of condensation on the barrel wall, the flow guide component guides a small amount of cold air in the air duct 4 through the molecular sieve desiccant to prevent the molecular sieve desiccant from becoming damp and caking, thus extending the service life of the molecular sieve desiccant.
[0069] As can be seen, during the operation of the sizing equipment in this embodiment, the drying device 7 can be introduced to dry the cold air as needed to prevent condensation from appearing on the wall of the sizing tank 2, which would affect the processing quality of materials such as aluminum alloys. When there is no risk of condensation, it is not necessary to introduce the drying device 7 to dry the cold air, thereby reducing the power consumption of the fan and extending the service life of the molecular sieve desiccant. This achieves dynamic control of the power consumption of the refrigeration unit 5 and the drying device 7 during temperature control, resulting in significant energy savings.
[0070] In another aspect of the embodiments of this disclosure, a temperature control method for a light-guiding device is provided, such as... Figure 5 As shown, it includes: S31. Obtain the temperature, humidity and dew point of the air outlet and air outlet 31, the temperature of the center and wall of the smoothing barrel 2, the rotation speed and load data of the smoothing barrel 2, and the condensation data of the barrel wall. S32. Determine whether the rotation speed and load of the smoothing barrel 2 are within the set range; As an example, the rotation speed of the polishing barrel 2 is set within the range of 100rpm-200rpm, and the load of the polishing barrel 2 is set within the range of 30%≤filling amount≤70%.
[0071] S33. In response to the fact that the speed and load of the slicker barrel 2 are not within the set range, adjust the air volume of the air outlet 31 and / or the power of the refrigeration unit 5. For example, for high-load conditions with a filling volume of ≥70% and a rotation speed of greater than 200 rpm, the air volume is increased by 20% in advance, and the compressor of the refrigeration unit is pre-frequency increased by 10 Hz to deal with the problem of sudden local heat accumulation that may occur in the light-reducing equipment, effectively avoiding a sudden temperature rise.
[0072] Similarly, for low-load / intermittent operating conditions with a filling volume of ≤30% and a speed of less than 100rpm, the compressor frequency can be reduced to 15-20Hz in advance, the air volume can be halved, and the system can enter a "low-energy heat preservation mode" to avoid wasting power consumption.
[0073] S34. Determine whether the center temperature of the polishing barrel 2, the temperature difference between the center of the polishing barrel 2 and the barrel wall are within the set range, and whether there is a risk of condensation on the barrel wall. S35. In response to the temperature of the center of the polishing barrel 2 and / or the temperature difference between the center of the polishing barrel 2 and the barrel wall being outside the set range, adjust the air volume of the air outlet 31 and / or the power of the refrigeration unit 5. S36. In response to the risk of condensation on the barrel wall, the cold air in the air duct 4 is dried.
[0074] Furthermore, the temperature control method for the light-guiding device also includes: In response to the speed and load of the smoothing barrel 2 exceeding the set range, and the temperature difference between the center and the barrel wall of the smoothing barrel 2 being within the set range and the temperature difference approaching the maximum value of the set range, the guide fan is started and / or the air volume of the air outlet 31 is increased and / or the power of the refrigeration unit 5 is increased.
[0075] By adopting the above technical solution, the air volume and / or power of the refrigeration unit 5 can be increased in advance according to the temperature difference trend, or the guide fan can be activated to cope with the high load conditions of the polishing equipment. This avoids the adjustment lag caused by only activating the adjustment mechanism when the temperature difference exceeds the maximum value of the set range, which leads to large temperature fluctuations in the polishing barrel 2 and sudden local heat accumulation affecting the polishing quality of the workpiece. By predicting the heating trend of the polishing barrel 2 in advance and taking targeted adjustment measures, the temperature control of the polishing barrel 2 can be kept stable.
[0076] The temperature control method of the shunting device in this embodiment has the following advantages: 1. The temperature inside the polishing barrel 2 can be stably controlled at 20-25℃ with an accuracy of ±2℃. The temperature difference between the center of the polishing barrel 2 and the barrel wall is ≤1℃, which completely eliminates local heat accumulation and avoids thermal expansion and contraction deformation and high-temperature oxidation of aluminum alloy parts.
[0077] 2. Condensation control: By predicting the dew point and intermittent drying, zero condensation risk is achieved, eliminating the need for additional costs to address the oxidation of aluminum alloy parts.
[0078] 3. Cost and energy consumption advantages: Compared with the traditional "continuous cooling + continuous drying" mode, the dynamic control strategy reduces compressor energy consumption by 30%-40%, dryer energy consumption by more than 60%, and overall operating costs by about 35%.
