Description

Technical Field

[0001] This invention relates to the field of thermal insulation material maintenance technology, specifically to a thermal insulation material maintenance control device and method based on PID control. Background Technology

[0002] In modern construction and industrial fields, the use of thermal insulation materials is becoming increasingly widespread, especially against the backdrop of growing demands for energy conservation, emission reduction, and comfortable environments. The performance and quality of thermal insulation materials play a crucial role in the energy efficiency, comfort, and durability of buildings. However, traditional thermal insulation material curing processes often rely on manual experience and lack systematic automated control, leading to unstable curing results. Therefore, the introduction of curing control devices based on PID (Proportional-Integral-Derivative) control technology has become an industry trend. This device uses high-precision sensors to monitor the temperature and humidity in the curing environment in real time and feeds the data back to the control system. The PID controller automatically adjusts the working status of heating, humidifying, or dehumidifying equipment according to the set target values, thereby maintaining the stability of curing conditions. This automated control can not only effectively avoid material defects such as cracking and peeling caused by temperature and humidity fluctuations, improving the overall performance and service life of thermal insulation materials, but also reduce the need for manual intervention, improving the efficiency and reliability of the curing process. In addition, the system can achieve long-term data recording, providing support for subsequent curing process optimization.

[0003] A Chinese patent (publication number: CN117415935B) discloses a steam curing device for wall insulation materials. This device has a placement groove at the top of a placement frame. Insulation materials are placed inside the groove. The position of an adjusting block is adjusted according to the specifications of the insulation material. Dragging an auxiliary pusher pulls the adjusting block, causing it to slide inside the auxiliary groove and move towards the insulation material, contacting its outer side. The area of ​​the placement groove is adjusted according to the specifications of the insulation material. This stable clamping of the insulation material ensures the curing requirements of different specifications. However, in actual curing, this device cannot cure the surface between the insulation material and the clamping block, resulting in temperature and humidity differences at the contact point with the clamping block compared to the overall surface. This inability to properly cure the insulation material as a whole reduces the curing effect and can cause the insulation material to crack. Summary of the Invention

[0004] The purpose of this invention is to solve the above problems by providing a PID-based thermal insulation material curing control device and method.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution: A PID-based thermal insulation material curing control device includes a curing box with a fixing mechanism inside. The fixing mechanism includes a placement platform, a venting plate, a first gear, a connecting rod, a second gear, a locking gear, an adjusting plate, a first servo motor, and a fixing plate. The fixing plate is fixedly connected to the placement platform, the first servo motor is fixedly connected to the fixing plate, the output shaft of the first servo motor is fixedly connected to the second gear, the second gear is rotatably connected to the fixing plate, one end of the connecting rod is fixedly connected to the second gear, the other end of the connecting rod is fixedly connected to the first gear, the second gear meshes with the locking gear, the locking gear is fixedly connected to the adjusting plate, the adjusting plate is slidably connected to the placement platform, the first gear meshes with the locking gear, and the venting plate is fixedly connected to the placement platform.

[0006] Furthermore, an adjustment mechanism is provided above the placement platform. The adjustment mechanism includes a clamp, an electric telescopic rod, a receiving plate, a receiving block, a second connecting block, and a second servo motor. The electric telescopic rod is fixedly connected to the adjustment plate, the output end of the electric telescopic rod is fixedly connected to the receiving plate, the receiving plate is fixedly connected to the second connecting block, the second connecting block is fixedly connected to the receiving block, the second servo motor is fixedly connected to the receiving block, the output shaft of the second servo motor is fixedly connected to the clamp, and the clamp is rotatably connected to the receiving block.

[0007] Furthermore, the curing box is internally fixedly connected with four sets of fixing blocks, and each of the four sets of fixing blocks has a slider slidably connected to its inner side. One side of each slider is fixedly connected to a connecting block, which is fixedly connected to the placement platform.

[0008] Furthermore, the fixed block has a sliding connection inside, and the locking block is fixedly connected to the slider.

[0009] Furthermore, a temperature and humidity display is fixedly installed on the surface of the curing box, and an adjustment switch is fixedly installed on the surface of the curing box.

[0010] Furthermore, a sensor is fixedly installed inside the curing box, an air jet is fixedly installed inside the curing box, and multiple sets of nozzles are fixedly installed inside the air jet, all of which are located on the same horizontal plane.

[0011] Furthermore, two sets of hinges are fixedly installed on one side of the maintenance box, and a box door is fixedly installed on one side of the two sets of hinges. A handle is rotatably connected to the surface of the box door.

[0012] Furthermore, a locking device is fixedly installed on the surface of the maintenance box, and a bolt is fixedly installed inside the handle, with the bolt slidingly inserted into the locking device.

[0013] Furthermore, four sets of bases are fixedly installed on the lower surface of the maintenance box, and all four sets of bases are located on the same horizontal plane.

[0014] The beneficial effects of this invention are as follows: 1. This invention uses a servo motor to drive gears 2 and 1 to rotate. The gears cause four sets of adjusting plates to move horizontally, allowing a pair of clamps to adhere to the insulation material, thus holding the insulation material. After a period of curing, the servo motor 1 causes the clamps adhering to the insulation material to detach from the surface of the insulation material, allowing another pair of clamps to adhere to and re-clamp the insulation material. This mechanism effectively avoids the problem of temperature and humidity differences between the clamping point and the overall material during curing, achieving a thorough curing effect. Simultaneously, it prevents cracking of the insulation material due to temperature and humidity differences, improving the curing effect of the device and further extending the service life of the insulation material.

[0015] 2. This invention uses an electric telescopic rod to move the clamp vertically upward, causing the insulation material to detach from the surface of the ventilated plate. Then, a second servo motor is activated, which drives the clamp to rotate, causing the insulation material to rotate with the clamp. Through gravity and the centrifugal force generated by the rotation, water droplets adhering to the surface of the insulation material are removed. This mechanism effectively avoids the problem of localized humidity imbalance caused by water droplets adhering to the surface of the insulation material, achieving the effect of removing surface water droplets. Simultaneously, it improves the accuracy of temperature and humidity regulation of the device. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0019] Example 1, as Figures 1-7 As shown, the thermal insulation material curing control device based on PID control includes a curing box 1. The curing box 1 has a fixing mechanism 3 inside. The fixing mechanism 3 includes a placement platform 31, a ventilation plate 32, a first gear 33, a connecting rod 34, a second gear 35, a locking gear 36, an adjusting plate 37, a first servo motor 38, and a fixing plate 39. The fixing plate 39 is fixedly connected to the placement platform 31. The first servo motor 38 is fixedly connected to the fixing plate 39. The output shaft of the first servo motor 38 is fixedly connected to the second gear 35. The second gear 35 is rotatably connected to the fixing plate 39. One end of the connecting rod 34 is fixedly connected to the second gear 35, and the other end of the connecting rod 34 is fixedly connected to the first gear 33. The second gear 35 meshes with the locking gear 36. The locking gear 36 is fixedly connected to the adjusting plate 37. The adjusting plate 37 is slidably connected to the placement platform 31. The first gear 33 meshes with the locking gear 36. The ventilation plate 32 is fixedly connected to the placement platform 31.

[0020] The PID controller automatically adjusts the operating status of heating, humidifying, or dehumidifying equipment according to the set target value, thereby maintaining the stability of the curing conditions. This automated control not only effectively avoids material defects such as cracking and peeling caused by temperature and humidity fluctuations, improving the overall performance and service life of the insulation material, but also reduces the need for manual intervention, improving the efficiency and reliability of the curing process. In addition, the system can record data for a long time, providing support for the optimization of subsequent curing processes. When curing the insulation material, the servo motor 38 drives the gears 35 and 33 to rotate, and the clamping gear 36 causes the four sets of adjusting plates 37 to move horizontally, so that a pair of clamps 41 are in contact with the insulation material, thereby clamping the insulation material. After a period of curing, the servo motor 38 causes the clamps 41 in contact with the insulation material to detach from the surface of the insulation material, so that another pair of clamps 41 are in contact with the insulation material and re-clamp the insulation material. By replacing the clamps 41 at regular intervals, the overall temperature and humidity of the insulation material are made the same, avoiding the failure of local areas to meet the curing standards.

[0021] Example 2, as Figure 4 , Figure 7 As shown, based on the above embodiment, an adjustment mechanism 4 is also provided above the placement platform 31. The adjustment mechanism 4 includes a clamp 41, an electric telescopic rod 42, a receiving plate 43, a receiving block 44, a second connecting block 45, and a second servo motor 46. The electric telescopic rod 42 is fixedly connected to the adjustment plate 37, the output end of the electric telescopic rod 42 is fixedly connected to the receiving plate 43, the receiving plate 43 is fixedly connected to the second connecting block 45, the second connecting block 45 is fixedly connected to the receiving block 44, the second servo motor 46 is fixedly connected to the receiving block 44, the output shaft of the second servo motor 46 is fixedly connected to the clamp 41, and the clamp 41 is rotatably connected to the receiving block 44. The electric telescopic rod 42 drives the clamp 41 to move vertically upward, causing the insulation material to detach from the surface of the vent plate 32. The second servo motor 46 is activated, causing the clamp 41 to rotate, so that the insulation material follows the clamp 41 to rotate, thereby removing the water droplets attached to the surface of the insulation material through gravity and the centrifugal force generated by the rotation.

[0022] Example 3, as Figure 3As shown, based on the above embodiment, it also includes four sets of fixing blocks 2 fixedly connected inside the curing box 1. Each of the four sets of fixing blocks 2 has a slider 21 slidably connected to its inner side. A connecting block 22 is fixedly connected to one side of the slider 21. The connecting block 22 is fixedly connected to the placement platform 31. A locking block 23 is slidably connected inside the fixing block 2. The locking block 23 is fixedly connected to the slider 21. Pulling the placement platform 31 outward causes the connecting block 22, slider 21, and locking block 23 to move horizontally outward with the placement platform 31, thereby pulling the placement platform 31 out of the curing box 1. When the placement platform 31 is pulled out to the outermost position, the locking block 23 prevents the placement platform 31 from falling off, thus facilitating the staff to take the insulation material.

[0023] Example 4, as Figure 1 , Figure 2 As shown, based on the above embodiment, it further includes a temperature and humidity display 13 fixedly installed on the surface of the curing chamber 1, an adjustment switch 12 fixedly installed on the surface of the curing chamber 1, a sensor 111 fixedly installed inside the curing chamber 1, an air jet 19 fixedly installed inside the curing chamber 1, and multiple sets of nozzles 110 fixedly installed inside the air jet 19, all of which are located on the same horizontal plane. The temperature and humidity inside the curing chamber 1 are set by adjusting the switch 12 and the temperature and humidity display 13. Water vapor is supplied to the inside of the curing chamber 1 by the air jet 19 and the nozzles 110. The temperature and humidity inside the curing chamber 1 are monitored by the sensor 111 to keep them within the set range. Then, based on the PID control algorithm, the system can automatically calculate the deviation between the current state and the set target, and adjust the power of the heater, humidifier or dehumidifier to quickly respond to environmental changes and ensure the stability of the curing conditions.

[0024] Example 5, such as Figure 1 As shown, based on the above embodiment, it also includes two sets of hinges 16 fixedly installed on one side of the maintenance box 1, a box door 17 fixedly installed on one side of the two sets of hinges 16, a handle 15 rotatably connected to the surface of the box door 17, a latch 11 fixedly installed on the surface of the maintenance box 1, a door bolt 14 fixedly installed inside the handle 15, the door bolt 14 and the latch 11 slidably inserted into each other, and four sets of bases 18 fixedly installed on the lower surface of the maintenance box 1. The four sets of bases 18 are all located on the same horizontal plane. The latch 11 and the door bolt 14 prevent the box door 17 from being accidentally opened during maintenance, thereby improving the stability of the device during use.
