Description

Technical Field

[0001] This application relates to the field of paper-faced gypsum board technology, and more specifically, to an online moisture detection device for the drying process of paper-faced gypsum board. Background Technology

[0002] Paper-faced gypsum board is a type of board made from building gypsum as the main raw material, with appropriate additives and fibers mixed in as the core, and special paper as the facing. Paper-faced gypsum board is lightweight, soundproof, heatproof, has strong processing performance, and is easy to construct, so it is widely used in interior decoration.

[0003] If the paper-faced gypsum board is not dried sufficiently during the production process, resulting in a high moisture content, it will greatly affect the quality and performance of the paper-faced gypsum board. The presence of a large number of water molecules will weaken the internal bonding force of the gypsum, significantly reducing its strength and seriously affecting the quality of decoration and posing a hidden danger to decoration safety. Therefore, it is necessary to test the moisture content of the paper-faced gypsum board multiple times during the production process, and it can only proceed to the next process after drying to the specified qualified index.

[0004] To address the aforementioned issues, this application provides an online moisture detection device for the drying process of paper-faced gypsum board. Utility Model Content

[0014] The above technical solution, by setting up support blocks, can provide support for the mesh tray.

[0015] Furthermore, a mesh support plate is fixedly connected to the top of the support block, the mesh support plate is located at the bottom of the paper-faced gypsum board, and a connecting plate is fixedly connected to the top of the mesh support plate.

[0016] The above technical solution, by setting up a mesh support plate, can support the paper-faced gypsum board, making it more stable when the paper-faced gypsum board moves left and right.

[0017] Furthermore, an electric push rod and two telescopic rods are fixedly connected between the connecting plate and the placement frame. The two telescopic rods are located on the front and rear sides of the electric push rod. A sealing door is provided on the front side of the drying box, and the sealing door is movably connected to the drying box by a hinge.

[0018] The above technical solution, by setting a hinge, facilitates the closing and opening of the sealed door later. The sealed door is made of transparent material.

[0019] In summary, this application includes the following beneficial technical effects:

[0020] In use, the paper-faced gypsum board can be placed on the mesh tray inside the drying oven, located inside the placement rack. After the drying oven has dried the paper-faced gypsum board for the specified time, the electric push rod can be activated to move the moisture detection sensor downwards until it contacts the paper-faced gypsum board. At this time, the moisture detection sensor will transmit the detected signal to the controller. After the data transmission is completed, the controller will analyze and process the signal collected by the moisture detection sensor and display the data on the display screen for easy monitoring by staff. At this time, the working indicator light will be on normally. However, when the system malfunctions, the central processing unit will send a signal to the alarm, causing the alarm to sound and notify the staff to handle the situation promptly.

[0032] The testing mechanism includes a placement rack 2, which is embedded inside the drying oven 1. A paper-faced gypsum board body 3 is embedded inside the placement rack 2. A moisture detection sensor 4 is installed on the top of the paper-faced gypsum board. An electric push rod 5 is fixedly connected between the moisture detection sensor 4 and the inner wall of the top of the drying oven 1. A controller 6 is installed on the top of the drying oven 1. The controller 6 is connected to the moisture detection sensor 4 through a sensor lead 7. The electric push rod 5 is sleeved on the outside of the sensor lead 7. An alarm 8 and a central processing unit 9 are installed on one side of the controller 6. Both the alarm 8 and the central processing unit 9 are installed on the top of the drying oven 1. The controller 6 is electrically connected to the input terminal of the central processing unit 9, and the central processing unit 9 is electrically connected to the input terminal of the alarm 8.

[0033] Please see Figure 1 and Figure 3 The outer side of the paper-faced gypsum board body 3 is provided with an adjustment component, which includes a guide groove. The guide groove is opened on the inner wall of the bottom of the drying box 1. A handle 10 is provided on the front side of the drying box. A screw 11 is fixedly connected to the rear side of the handle 10. The rear end of the screw 11 passes through the guide groove and extends into the interior of the drying box 1. The connection between the screw 11 and the drying box 1 is movably connected by a bearing.

[0034] Please see Figure 1 , Figure 2 and Figure 3 A screw block 12 is screwed onto the outer wall of the screw 11. The screw block 12 matches the guide groove. A support block 13 is fixedly connected to the top of the screw block 12. A mesh support plate 14 is fixedly connected to the top of the support block 13. The mesh support plate 14 is located at the bottom of the paper-faced gypsum board. A connecting plate 15 is fixedly connected to the top of the mesh support plate 14.

[0035] Please see Figure 1 An electric push rod 16 and two telescopic rods 17 are fixedly connected between the connecting plate 15 and the placement rack 2. The two telescopic rods 17 are located on the front and rear sides of the electric push rod 16, respectively. A sealing door is provided on the front side of the drying box 1, and the sealing door is movably connected to the drying box 1 by a hinge.

[0036] The implementation principle of this embodiment is as follows: When in use, the paper-faced gypsum board body 3 can be placed on the mesh tray 14 inside the drying oven 1. Because of the mesh tray 14, the bottom of the paper-faced gypsum board body 3 can also be dried evenly. And it is located inside the placement rack 2.

[0037] During this process, the screw 11 can be rotated by turning the handle 10 in both directions. Since the guide groove matches the screw block 12, the support block 13 can be moved back and forth by the screw block 12. Subsequently, the mesh tray 14, connecting block, two telescopic rods 17, electric push rod 2 16, and placement frame 2 will move the paper-faced gypsum board body 3 back and forth. At the same time, the electric push rod 2 16 can be activated to move the paper-faced gypsum board body 3 back and forth in the left and right directions through the placement frame 2. Through the above structure, the position of the paper-faced gypsum board body 3 can be adjusted flexibly and quickly, and moisture detection can be performed in multiple directions of the paper-faced gypsum board body 3, which has the effect of improving the moisture detection of the paper-faced gypsum board body 3.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
