Description

Technical Field

[0001] This utility model belongs to the technical field of calibration devices, and in particular relates to a calibration device for a wood moisture tester. Background Technology

[0002] Wood moisture meters are widely used in industries such as chemical, building materials, wood, papermaking, and food. The quality of raw materials directly affects the quality of industrial products, and the moisture content in wood is an important indicator for judging quality.

[0003] Wood moisture testers are mainly used to measure the moisture content of wood, which is particularly important for quality control of raw materials during the production process.

[0004] Existing equipment often has limitations when drying wood boards. Due to the limited drying angle, the wood boards may not be able to effectively remove the moisture they contain. This results in a certain error in the moisture content value obtained when comparing the weight of the wood boards with that of undried wood boards. Therefore, we propose a calibration device for a wood moisture meter. Utility Model Content

[0005] The purpose of this invention is to provide a calibration device for a wood moisture tester. Through a drying mechanism and a cleaning mechanism, it solves the problem that when drying a whole board, the drying angle is often limited, and the moisture contained in the board may not be effectively removed, resulting in a certain error in the value of the moisture content of the board when compared with the weight of an undried board.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a calibration device for a wood moisture tester, including a support base, a base fixedly connected to the bottom outer wall of the support base, and a drying mechanism provided on the top outer wall of the support base.

[0008] The drying mechanism includes a tilting seat, the bottom outer wall of which is fixedly connected to the top outer wall of a support seat. A drying chamber is fixedly connected to the top outer wall of the tilting seat, and a heat lamp is fixedly connected to the inner wall of the drying chamber. A sliding groove is provided on the inner wall of the tilting seat, and a threaded rod is rotatably connected to the inner wall of the sliding groove. A throttle is fixedly connected to the outer wall of the threaded rod, and a slider is drivenly connected to the outer wall of the threaded rod. The outer wall of the slider is slidably connected to the inner wall of the sliding groove.

[0009] Furthermore, the outer wall of the slider is rotatably connected to a connecting shaft, the outer wall of the connecting shaft is rotatably connected to a fixed frame, the outer wall of the fixed frame near the threaded rod is fixedly connected to a rotating shaft, the outer wall of the rotating shaft is rotatably connected to a connecting rod, and the inner wall of the connecting rod is rotatably connected to a second rotating shaft.

[0010] Furthermore, the outer wall of the rotating shaft II is fixedly connected to the inner wall of the flipping seat, the inner wall of the fixing frame is provided with a plurality of sliding grooves II, the inner wall of the sliding grooves II is slidably connected with a plurality of clamping plates, the outer wall of the clamping plates is fixedly connected with a spring, the outer wall of the spring is fixedly connected to the inner wall of the sliding grooves II, and the outer wall of the drying unit is hinged with a transparent protective door.

[0011] Furthermore, the inner wall of the support base is provided with a cleaning mechanism, which includes several spring telescopic rods. The bottom outer wall of each spring telescopic rod is fixedly connected to the inner wall of the support base, and a placement plate is fixedly connected to the top outer wall of each spring telescopic rod.

[0012] Furthermore, a weighing instrument is fixedly connected to the outer wall of the support base, a motor is fixedly connected to the outer wall of the support base, a transmission rod is fixedly connected to the bottom output shaft of the motor through a coupling, and a transmission wheel is fixedly connected to the outer wall of the transmission rod.

[0013] Furthermore, a transmission belt is connected to the outer wall of the transmission wheel, and a second transmission wheel is connected to the inner wall of the end of the transmission belt away from the transmission wheel. A second threaded rod is fixedly connected to the outer wall of the second transmission wheel.

[0014] Furthermore, the outer wall of the threaded rod 2 is rotatably connected to several bearings, the bottom outer wall of the bearings is fixedly connected to the outer wall of the support seat, and the outer wall of the threaded rod 2 is drivenly connected to a brush plate.

[0015] Furthermore, the inner wall of the support base is provided with a sliding groove three, and the inner wall of the sliding groove three is slidably connected to the outer wall of the brush plate.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model features a fixed frame where several clamping plates, under the action of springs, clamp the wooden board for fixation. When the heat lamp is activated, it dries the board from top to bottom to remove its moisture. During this process, the handle can be rotated, causing the threaded rod to rotate. The threaded rod then moves the slider towards the handle, which in turn moves the connecting shaft. The connecting shaft then moves one end of the fixed frame to rotate, causing it to flip. The fixed frame then rotates the clamping plates, achieving thorough drying of the entire wooden board. This drying process effectively removes the internal moisture. By comparing the weight of the dried board with that of an undried board, the moisture content of the board can be accurately determined. The operation is convenient, and the measurement results are accurate and reliable.

[0018] 2. This utility model, by incorporating a brush plate, allows for the comparison of the weight of undried and dried wooden boards to determine the original moisture content. If any debris or foreign matter remains on the surface of the board, the motor can be activated. The motor drives a transmission rod to rotate, which in turn drives a transmission wheel, which in turn drives a transmission belt. The transmission belt then drives a second transmission wheel, which in turn drives a second threaded rod. This threaded rod displaces the brush plate, which removes any foreign matter from the board surface during this displacement. This allows for quick cleaning of the board surface before use, ensuring sufficient accuracy in the weight measurements.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
