A gypsum board production line panel temperature on-line monitoring system and method

Abstract

The application discloses a gypsum board production line board surface temperature on-line monitoring system and method, wherein the system is provided with a temperature monitoring structure, a multi-point monitoring driving structure, a layer adaptive height adjusting device and an anti-collision acceleration component. The anti-collision acceleration component drives the temperature monitoring structure to rotate and move close to the layer adaptive height adjusting device, so that the temperature monitoring structure is separated from the adjacent layers of the multi-layer board discharge roller way at a driving speed faster than that of the multi-point monitoring driving structure. In the application, the anti-collision acceleration component drives the temperature monitoring structure to accelerate the separation from the adjacent layers of the multi-layer board discharge roller way, so that the temperature monitoring structure avoids colliding on the roller way between the layers. In addition, the slowest arrival time point of the temperature monitoring structure is calculated according to the discharge time point, and the patrol path and the patrol speed are adjusted, so that the temperature monitoring structure reaches the corresponding layer before the slowest arrival time point, thereby avoiding the situation that the temperature is not collected in time due to the fact that the polling temperature collection work has not reached the corresponding layer after the gypsum board is discharged.

Description

Technical Field

[0001] This invention relates to the field of gypsum board temperature detection technology, specifically to an online monitoring system and method for the surface temperature of gypsum board production lines. Background Technology

[0002] Temperature control of the gypsum board production line is a crucial step in the production process, directly impacting product quality. Excessive or insufficient surface temperature after the gypsum has fully set can lead to issues such as non-adhesive facing paper, board cracking, and energy waste. Furthermore, it can result in defective products at the dryer outlet due to low or overheated boards, causing significant losses.

[0003] Infrared temperature sensors are usually installed on gypsum board production lines to collect the temperature of the gypsum board surface in real time. The dryer outlet on the gypsum board production line usually transports the gypsum board in multiple layers through multi-layer discharge roller conveyors. In order to reduce costs, a single infrared temperature sensor is used instead of setting an infrared temperature sensor on each layer. The single infrared temperature sensor polls and scans the temperature to collect the temperature of the corresponding layer where gypsum board has entered.

[0004] However, existing polling temperature acquisition technology requires sequential temperature acquisition of each layer when multiple layers of gypsum board enter at the same time. With a fixed gypsum board transport speed, there is a possibility that the polling temperature acquisition work may not have reached the corresponding layer after the gypsum board is discharged, resulting in the temperature not being acquired in time. This situation can be reduced by speeding up the polling acquisition speed, but excessively fast temperature acquisition may cause the corresponding temperature acquisition equipment to collide with the roller conveyor between layers, damaging the temperature acquisition equipment. Summary of the Invention

[0005] To address this issue, the present invention provides an online temperature monitoring system and method for gypsum board production lines, which effectively solves the problems in the prior art where the temperature acquisition work has not yet reached the corresponding layer after the gypsum board is discharged, resulting in the temperature not being collected in time, and where the high-speed temperature acquisition work may cause the corresponding temperature acquisition equipment to collide with the roller conveyor between layers, causing damage to the temperature acquisition equipment.

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] like Figure 1 As shown, the present invention provides an online monitoring system and method for the surface temperature of gypsum board production line, wherein the system comprises a temperature monitoring structure 1, a multi-point monitoring drive structure 2, a layer adaptation height adjustment device 3, and an anti-collision acceleration component 4.

[0052] The temperature monitoring structure 1 is installed on the side of the multi-layer output roller conveyor 5. The temperature monitoring structure 1 is used to monitor the temperature of the gypsum board surface that reaches the multi-layer output roller conveyor 5.

[0053] The multi-point monitoring drive structure 2 is set on the side of the multi-layer board conveyor 5, and the temperature monitoring drive structure 1 is set on the multi-point monitoring drive structure 2 and can follow the movement of the multi-point monitoring drive structure 2. The multi-point monitoring drive structure 2 is used to drive the temperature monitoring drive structure 1 to move along a fixed monitoring path above the gypsum board surface to form a fixed detection area on the gypsum board surface, and to enable the temperature monitoring structure 1 to perform fixed-point temperature detection within the fixed detection area.

[0054] The layer adaptation height adjustment device 3 is set on the side of the multi-layer board output roller 5, the multi-point monitoring drive structure 2 is set on the layer adaptation height adjustment device 3, and the temperature monitoring structure 1 is set on the layer adaptation height adjustment device 3. The layer adaptation height adjustment device 3 is used to drive the temperature monitoring structure 1 to rise and fall to the side of the corresponding layer of the multi-layer board output roller 5 through the multi-point monitoring drive structure 2 when the gypsum board reaches the multi-layer board output roller 5.

[0055] The anti-collision acceleration component 4 is set on the multi-point monitoring drive structure 2, and the temperature monitoring structure 1 is installed on the anti-collision acceleration component 4. The anti-collision acceleration component 4 is used to drive the temperature monitoring structure 1 to rotate and move closer to the layer adaptation height adjustment device 3 after the temperature monitoring structure 1 completes temperature detection, so that the temperature monitoring structure 1 can leave the adjacent layers of the multi-layer output roller table 5 at a speed faster than the driving speed of the multi-point monitoring drive structure 2.

[0056] In the above embodiments, in order for the temperature monitoring structure 1 to move and detect temperature simultaneously, the multi-point monitoring drive structure 2, the layer adaptation height adjustment device 3, and the anti-collision acceleration component 4 need to be driven simultaneously.

[0057] In this embodiment of the invention, an anti-collision acceleration component 4 is provided. After the temperature monitoring structure 1 completes temperature detection, it drives the temperature monitoring structure 1 to rotate and move closer to the layer adaptation height adjustment device 3, so that the temperature monitoring structure 1 can leave the adjacent layers of the multi-layer board discharge roller conveyor 5 at a driving speed faster than the multi-point monitoring drive structure 2, thus avoiding the temperature monitoring structure 1 from colliding with the roller conveyor between layers. In addition, the invention calculates the slowest arrival time of the temperature monitoring structure based on the material discharge time, adjusts the circulation path based on the slowest arrival time, and adjusts the circulation speed based on the slowest arrival time and the circulation path distance, so that the temperature monitoring structure 1 reaches the corresponding layer before the slowest arrival time, thus avoiding the situation where the temperature collection work has not reached the corresponding layer after the gypsum board is discharged, resulting in the temperature not being collected in time.

[0058] In this invention, temperature is detected by a temperature monitoring structure 1, which includes a mounting base 11 and a temperature sensor 12 disposed on the mounting base 11.

[0059] In the above embodiment, the temperature sensor 12 is mounted on the mounting base 11. At least one temperature sensor 12 is provided. The temperature sensor 12 is used to detect the temperature of the gypsum board surface. The setting of multiple temperature sensors 12 may collect the temperature at different locations on the same gypsum board surface, which increases the accuracy of the final detected temperature.

[0060] In order to detect the gypsum board entering each layer of the multi-layer output roller conveyor 5, the present invention also makes the following design: a mounting frame 13 is provided at the feeding end of each corresponding layer of the multi-layer output roller conveyor 5, and a photoelectric sensor 14 is provided on the mounting frame 13.

[0061] In the above embodiment, the photoelectric sensor 14 is used to measure the gypsum board entering each corresponding layer of the multi-layer output roller conveyor 5. When the gypsum board passes directly below the photoelectric sensor 14, the photoelectric sensor 14 can detect that the gypsum board has entered the corresponding layer of the multi-layer output roller conveyor 5.

[0062] The multi-layer board output roller conveyor 5 of the present invention is configured with multiple transport roller conveyors to transport gypsum boards. The specific structure is as follows: the multi-layer board output roller conveyor 5 consists of a mounting frame 51 and a conveying roller 52; one mounting frame 51 and several conveying rollers 52 constitute one layer of the multi-layer board output roller conveyor. The conveying rollers 52 are rotatably mounted on the mounting frame 51, and the conveying rollers 52 drive the gypsum boards to be transported forward.

[0063] In this invention, when the gypsum board reaches the multi-layer output roller conveyor 5, the layer-adaptive height adjustment device 3 uses a multi-point monitoring drive structure 2 to drive the temperature monitoring structure 1 to rise and fall to the side of the corresponding layer on the multi-layer output roller conveyor 5. The layer-adaptive height adjustment device 3 of this invention adopts the following preferred embodiments, such as... Figure 2 and Figure 3 As shown, the layer adaptation height adjustment device 3 includes a lifting seat 31 disposed on the layer adaptation height adjustment device 3, a mounting base 32 disposed on the side of the multi-layer output roller conveyor 5, and a gear column 33 disposed on the mounting base 32; the gear column 33 is disposed through the lifting seat 31, and a driving cavity 34 is disposed inside the lifting seat 31. The inner wall of the driving cavity 34 is provided with a through groove 35 for the gear column 33 to pass through, and the inner wall of the through groove 35 fits with the outer wall of the gear column 33.

[0064] In the above embodiments, the lifting seat 31 is liftable, and during the lifting process, the lifting seat 31 rises or falls along the gear column 33.

[0065] In order to drive the lifting seat 31 to rise and fall, the present invention also makes the following design: a first drive motor 36 is provided in the drive cavity 34, and a drive gear 37 is connected to the output end of the first drive motor 36. The drive gear 37 meshes with the side of the gear column 33.

[0066] The first drive motor 36 drives the drive gear 37 to rotate. Under the rotation of the drive gear 37, the drive gear 37 and the gear column 33 move relative to each other. Since the gear column 33 is fixed, the drive gear 37 itself gradually moves up or down under the rotation of the drive gear 37, thereby driving the lifting seat 31 to move up or down.

[0067] The multi-point monitoring drive structure 2 drives the temperature monitoring drive structure 1 to move along a fixed monitoring path above the gypsum board surface, forming a fixed detection area on the gypsum board surface, and enabling the temperature monitoring structure 1 to perform fixed-point temperature detection within the fixed detection area. The multi-point monitoring drive structure 2 of this invention adopts the following preferred embodiments, such as... Figure 2 and Figure 4 As shown, the multi-point monitoring drive structure 2 includes a limiting post 21 set on the lifting seat 31, a connecting ring seat 22 rotatably set on the limiting post 21, and a gear ring 23 set in the connecting ring seat 22; the inner wall of the gear ring 23 fits with the outer wall of the limiting post 21, and the anti-collision acceleration component 4 is installed on the connecting ring seat 22.

[0068] In this embodiment, the limiting post 21 limits the rotation of the gear ring 23 and the rotation of the connecting ring seat 22. In order to drive the gear ring 23 to rotate, the present invention also makes the following design: an installation notch 24 is opened on one side of the limiting post 21, and a transmission gear 25 is arranged in the installation notch 24. The transmission gear 25 meshes with the gear ring 23. A second drive motor 27 is arranged on the transmission gear 25. The transmission gear 25 is connected to the output end of the second drive motor 27. The second drive motor 27 is arranged in the drive cavity 34.

[0069] In the above embodiment, the second drive motor 27 drives the transmission gear 25 to rotate, the transmission gear 25 drives the gear ring 23 to rotate on the limiting post 21, thereby driving the connecting ring seat 22 to rotate. The anti-collision acceleration component 4 is installed on the connecting ring seat 22. The rotation of the connecting ring seat 22 drives the anti-collision acceleration component 4 to rotate. Under the combined action of the translational movement of the gypsum board, the temperature monitoring structure 1 forms a fixed detection area on the surface of the gypsum board. The temperature sensor 12 collects temperature data at regular intervals, thus performing fixed-point temperature detection within the fixed detection area.

[0070] In this invention, after the temperature monitoring structure 1 completes temperature detection, the anti-collision acceleration component 4 drives the temperature monitoring structure 1 to rotate and move closer to the layer adaptation height adjustment device 3, so that the temperature monitoring structure 1 can disengage from the adjacent layers of the multi-layer output roller conveyor 5 at a speed faster than the driving speed of the multi-point monitoring drive structure 2. The anti-collision acceleration component 4 of this invention adopts the following preferred embodiments, such as... Figure 2 and Figure 5 As shown, the anti-collision acceleration component 4 includes a connecting arc groove 41 disposed on the connecting ring seat 22, a connecting arc seat 42 slidably disposed in the connecting arc groove 41, and a gear ring 43 disposed in the connecting arc seat 42; a connecting gear 44 is meshed on the side of the gear ring 43, and a third drive motor 45 is connected to the connecting gear 44, and the connecting gear 44 is connected to the output end of the third drive motor 45.

[0071] In the above embodiment, the third drive motor 45 drives the connecting gear 44 to rotate. Under the action of the rotation of the connecting gear 44, the gear ring 43 rotates, thereby driving the connecting arc seat 42 to rotate. The rotation of the connecting arc seat 42 can drive the temperature monitoring structure 1 to rotate.

[0072] In order to enable the rotation of the connecting arc seat 42 to drive the temperature monitoring structure 1 to rotate, the present invention also makes the following design: a rotating seat 46 is provided on the connecting arc seat 42, and a translation drive cylinder 47 is provided on the rotating seat 46. The output end of the translation drive cylinder 47 is drivenly connected to the mounting base 11.

[0073] The rotation of the connecting arc seat 42 can drive the rotating seat 46 to rotate, thereby causing the mounting seat 11 to rotate faster under the rotation of the connecting ring seat 22. The translation drive cylinder 47 can also drive the mounting seat 11 to translate.

[0074] In summary, the main implementation process of this invention is as follows:

[0075] The entry of gypsum board is detected: when the gypsum board passes directly below the photoelectric sensor 14, the photoelectric sensor 14 can detect that the gypsum board has entered the corresponding layer of the multi-layer output roller conveyor 5.

[0076] Temperature monitoring structure 1 is raised or lowered to the corresponding layer: The first drive motor 36 drives the drive gear 37 to rotate. Under the action of the rotation of the drive gear 37, the drive gear 37 and the gear column 33 move relative to each other, thereby driving the lifting seat 31 and the temperature monitoring structure 1 to move up or down to the corresponding layer.

[0077] Start the temperature monitoring program: The second drive motor 27 drives the transmission gear 25 to rotate, the transmission gear 25 drives the gear ring 23 to rotate on the limit post 21, thereby driving the connecting ring seat 22 to rotate. The anti-collision acceleration component 4 is installed on the connecting ring seat 22. The rotation of the connecting ring seat 22 drives the anti-collision acceleration component 4 to rotate. Under the combined action of the translational movement of the gypsum board, the temperature monitoring structure 1 forms a fixed detection area on the surface of the gypsum board. The temperature sensor 12 collects the temperature at regular intervals. Therefore, fixed-point temperature detection is performed within the fixed detection drive.

[0078] The temperature monitoring structure 1 is driven to detach from the current layer: The third drive motor 45 drives the connecting gear 44 to rotate. Under the action of the rotation of the connecting gear 44, the gear ring 43 rotates, thereby driving the connecting arc seat 42 to rotate. The rotation of the connecting arc seat 42 can drive the temperature monitoring structure 1 to rotate. Under the action of the rotation of the connecting ring seat 22, the rotation is accelerated, driving the translation drive cylinder 47 to drive the mounting base 11 to retract, so that the temperature monitoring structure 1 accelerates to detach from the current layer.

[0079] The present invention provides a monitoring method for an online monitoring system for the surface temperature of gypsum board production lines, comprising the following steps:

[0080] Step 100: Monitor the entry of gypsum board into the multi-layer output roller conveyor 5 and record the corresponding layer of the multi-layer output roller conveyor 5 where gypsum board has entered.

[0081] Step 200: The temperature monitoring structure 1 analyzes the corresponding layer of the multi-layer output roller conveyor 5 into which gypsum board enters to obtain the corresponding circulation path, and performs circulation action according to the circulation path.

[0082] Step 300: Temperature monitoring structure 1 triggers the temperature monitoring program at the corresponding layer of the multi-layer output roller conveyor 5 where gypsum board enters.

[0083] Step 400: Calculate the discharge time of the gypsum board from the corresponding layer of the multi-layer discharge roller conveyor 5 based on the transport speed and length of the gypsum board.

[0084] Step 500: Calculate the slowest arrival time of temperature monitoring structure 1 based on the discharge time, and adjust the circulation path based on the slowest arrival time.

[0085] Step 600: Adjust the patrol speed based on the slowest arrival time and the patrol path distance.

[0086] In step 200, the corresponding circulation path is obtained based on the corresponding layer of the multi-layer board exit roller conveyor 5 where gypsum board enters. The above work is performed when there is only one corresponding layer of the multi-layer board exit roller conveyor 5 where gypsum board enters. Assuming there are 6 roller conveyors, from bottom to top, they are roller conveyor layers 1, 2, 3, 4, 5, and 6. Assuming the temperature monitoring structure 1 is currently located at roller conveyor layer 3, and the corresponding layer of the multi-layer board exit roller conveyor 5 where gypsum board enters is detected is roller conveyor layer 1, then the obtained circulation path is from roller conveyor layer 3 to roller conveyor layer 1.

[0087] Assuming that there are multiple layers in the multi-layer output roller conveyor 5 where gypsum board enters, it is necessary to determine the urgency of each layer. The specific implementation steps are steps 400, 500, and 600.

[0088] The main processes in steps 400, 500, and 600 are as follows:

[0089] First, calculate the discharge time of the gypsum board from the corresponding layer of the multi-layer discharge roller conveyor 5 based on the transport speed and length of the gypsum board.

[0090] The slowest arrival time of temperature monitoring structure 1 is calculated based on the discharge time. Assuming the discharge time is t1 and the time from the temperature monitoring structure 1 entering the corresponding layer to completing temperature detection is T, then the slowest arrival time of temperature monitoring structure 1 is t1-T.

[0091] The patrol path is adjusted based on the slowest arrival time. The preferred list of slowest arrival times closest to the current time is selected as the destination of the patrol path. Assuming that the slowest arrival times closest to the current time are arranged as roller layers 1, 3, 4, and 6, and the current position is roller layer 5, the patrol path needs to be adjusted to go to roller layer 1 first and then roller layer 6. During the journey from roller layer 5 to roller layer 1, temperature data can be collected on roller layers 3 and 4 at the same time. Temperature data collection is performed while passing through the roller layers.

[0092] The patrol speed is adjusted based on the slowest arrival time and the patrol path distance. The required time can be calculated based on the slowest arrival time and the current time. The patrol path distance can be calculated based on the current location and the target location. The required slowest patrol speed can be obtained by comparing the patrol path distance and the required time. The rotation speed of the first drive motor 36 is adjusted so that the temperature monitoring structure 1 rises and falls at a speed not lower than the slowest patrol speed.

[0093] During the speed adjustment process, it is also necessary to pay attention to the anti-collision acceleration component 4 driving the temperature monitoring structure 1 to rotate faster and move closer to the layer adaptation height adjustment device 3, so that the temperature monitoring structure 1 can quickly move away from the adjacent layers of the multi-layer output roller table 5.
