Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically to an online detection and sorting device for wood moisture content. Background Technology

[0002] The moisture content of wood directly affects its physical and mechanical properties. Excessive moisture content can cause wood to swell, deform, or even crack, affecting its service life and appearance quality. Therefore, it is necessary to test the moisture content of wood during the production and processing process. Nowadays, non-contact moisture analyzers are usually used for this test.

[0003] A search revealed an existing patent (publication number: CN218546671U) disclosing an online moisture content detection device for wood panels, relating to the field of wood panel testing. Addressing the problem of low efficiency caused by the inability to continuously detect moisture content in existing wood panel testing methods, this invention proposes the following solution: It includes a material bin and a wood moisture meter. A fixing plate is fixedly installed at the front end of the material bin, and a cylinder is fixedly installed at the top of the fixing plate. The piston rod of the cylinder passes through the fixing plate and is fixedly installed with the wood moisture meter. A discharge port is opened on the side of the material bin near the fixing plate, and the discharge port is located below the fixing plate. Symmetrically distributed support plates are fixedly installed on both sides of the material bin, and a drive motor is fixedly installed on the side of one of the support plates furthest from the material bin. This invention features a novel structure, and the device can replace manual labor to continuously detect the moisture content of wood panels, thus improving the detection efficiency.

[0004] However, the above method is inconvenient to clean the wood surface. In the actual testing process, some wood chips may remain on the wood surface, which will affect the accuracy of moisture content measurement and thus cause certain measurement errors, affecting subsequent sorting operations.

[0005] In view of this, the present invention proposes an online detection and sorting device for wood moisture content. Utility Model Content

This achieves the cleaning of wood chips from the wood surface, preventing them from affecting the accuracy of the moisture content detection instrument. After the detection and sorting operation is completed, the chip collection box can be slid out for convenient centralized processing of the collected wood chips, thus improving its practicality.

[0018] In this invention, when the moisture meter detects a high moisture content in the wood board, the reduction motor is activated to rotate the thrust plate until it is perpendicular to the conveyor belt. Then, as the conveyor belt moves the wood board with high moisture content, one end of the wood board contacts the pressure sensor, and the conveyor belt stops working. Then, the sorting pneumatic telescopic rod is activated to move the push plate, pushing the wood board and guiding it out by the unloading plate. When the moisture content of the wood board is found to be within acceptable limits, the thrust plate rotates to be horizontal with the machine body. Afterward, the wood board is guided and transported away by the conveyor belt, thus realizing automatic sorting of wood boards and avoiding the tedious inconvenience of manual sorting.

[0027] A preferred embodiment of the online wood moisture content detection and sorting device provided by this utility model is, for example... Figures 1 to 5 As shown: An online detection and sorting device for wood moisture content includes a body 7; a controller 8 fixedly connected to one side of the front of the body 7, and a conveyor belt 6 installed at the upper end inside the body 7; a fixed frame 3 fixedly connected to the top of the body 7, with a lifting pneumatic telescopic rod 2 fixedly connected to one end of the top of the fixed frame 3, the output end of the lifting pneumatic telescopic rod 2 passing through the upper end of the fixed frame 3 and fixedly connected to a sliding plate 10, and moisture detectors 13 fixedly connected to both ends of the bottom of the sliding plate 10; a chip removal component 4 assembled on one side of the top of the body 7, which is used to clean wood chips from the surface of the wood; and a sorting component 9 assembled on the other side of the top of the body 7, which is used for automatically pushing and sorting wood with excessive moisture content.

[0028] The chip removal assembly 4 includes: an air outlet box 403 fixedly connected to one side of the top of the machine body 7; a blower 402 fixedly connected to the upper end of one side of the front of the machine body 7; the output end of the blower 402 is connected to the interior of the air outlet box 403 through a duct; a chip inlet hood 401 fixedly connected to the top of the machine body 7; sliding grooves 405 are provided on both sides of the bottom end of the chip inlet hood 401; a chip collection box 404 is provided at the bottom end of the chip inlet hood 401; and sliding plates 406 are fixedly connected to both sides of the top of the chip collection box 404.

[0029] In this embodiment, by starting the blower 402, external air is delivered into the air outlet box 403, and then sprayed out through the through hole on one side of the air outlet box 403, blowing the wood chips on the surface of the wood towards the chip inlet hood 401, which then enters the chip inlet hood 401 and falls into the chip collection box 404. The blown air is discharged through the small hole on one side of the chip collection box 404, while the wood chips remain inside the chip collection box 404, thus cleaning the wood chips on the surface of the wood and preventing them from affecting the accuracy of the moisture content detection of the moisture detector 13.

[0030] In a further preferred embodiment of the present invention, the area of ​​the cross-sectional opening on one side of the chip inlet hood 401 is larger than the area of ​​the cross-sectional opening on one side of the air outlet box 403, and the upper end of the inner wall of the chip inlet hood 401 is inclined.

[0031] In this embodiment, the sawdust blown by the air outlet box 403 can more easily enter the inside of the sawdust inlet 401 by utilizing the sawdust inlet hood 401 with a larger opening area.

[0036] Based on Example 1, a preferred embodiment of the online wood moisture content detection and sorting device provided by this utility model is as follows: Figures 1 to 5 As shown: The sorting assembly 9 includes: a fixed plate 902 fixedly connected to one side of the top of the machine body 7, a sorting pneumatic telescopic rod 901 fixedly connected to one end of the fixed plate 902, the output end of the sorting pneumatic telescopic rod 901 passing through the fixed plate 902 and fixedly connected to a push plate 904; a mounting bracket 905 fixedly connected to one side of the top of the machine body 7, a geared motor 906 fixedly connected to one side of the top of the mounting bracket 905, the output end of the geared motor 906 passing through the upper end of the mounting bracket 905 and fixedly connected to a thrust plate 903 through a coupling, and a pressure sensor 907 fixedly connected to one side of the thrust plate 903.

[0037] In this embodiment, when the moisture detector 13 detects that the moisture content of the wood board is high, the geared motor 906 is started to drive the thrust plate 903 to rotate to be perpendicular to the conveyor belt 6. When one end of the wood board comes into contact with the pressure sensor 907, the conveyor belt 6 stops working. Then the sorting pneumatic telescopic rod 901 is started to drive the push plate 904 to move, pushing the wood board and guiding it out by the unloading plate 1. When the moisture content of the wood board is qualified, the wood board is directly guided and transported away by the conveyor belt 6.

[0038] In a further preferred embodiment of the present invention, a discharge plate 1 is fixedly connected to the upper end of the body 7 at the end away from the fixed plate 902, and the top of the discharge plate 1 is inclined at an angle of 20 degrees to the horizontal direction.

[0039] In this embodiment, the inclined unloading plate 1 is used to facilitate the discharge of wood boards with high moisture content.

[0040] In a further preferred embodiment of the present invention, a limiting groove 12 is provided on the inner wall of the fixing frame 3, and a limiting plate 11 that slides and cooperates with the inside of the limiting groove 12 is fixedly connected to one end of the sliding plate 10.

[0041] In this embodiment, the sliding of the limiting plate 11 inside the limiting groove 12 is used to improve the stability of the sliding plate 10 sliding up and down.

[0042] In a further preferred embodiment of the present invention, anti-slip patterns 5 are evenly spaced on the surface of the conveyor belt 6, and the anti-slip patterns 5 are triangular in shape.

[0043] In this embodiment, triangular anti-slip patterns 5 are used to improve the anti-slip properties of the wood board in contact with the conveyor belt 6.

[0044] The working principle of this utility model is as follows: First, the wood boards are conveyed by the conveyor belt 6. At this time, the blower 402 is started to deliver external air into the air outlet box 403. Then, the air is sprayed out through the through hole on one side of the air outlet box 403, which blows the wood chips on the surface of the wood towards the chip inlet hood 401. The chips then enter the chip inlet hood 401 and fall into the chip collection box 404. The blown air is discharged through the small hole on one side of the chip collection box 404, while the wood chips remain inside the chip collection box 404. This achieves the cleaning of wood chips on the surface of the wood and avoids affecting the accuracy of the moisture content detection by the moisture analyzer 13. After the detection and sorting operation is completed, the handle on the chip collection box 404 can be pulled to make the slide plate 406 slide out of the slide groove 405. Then, the chip collection box 404 can be slid out for centralized processing of the collected wood chips. During installation, the slide plate 406 is completely slid into the slide groove 405.

[0045] The pneumatically purged wood boards continue to be conveyed by the conveyor belt 6. At the same time, the lifting pneumatic telescopic rod 2 is activated to lower the sliding plate 10, causing the moisture detector 13 to descend to a suitable height to detect the moisture content of the wood boards. When the moisture detector 13 detects that the moisture content of the wood boards is high, the reduction motor 906 is activated to drive the thrust plate 903 to rotate until it is perpendicular to the conveyor belt 6. Then, as the conveyor belt 6 moves the wood boards with high moisture content, one end of the wood boards comes into contact with the pressure sensor 907, and the conveyor belt 6 stops working. Then, the sorting pneumatic telescopic rod 901 is activated to drive the push plate 904 to move, pushing the wood boards and guiding them out by the unloading plate 1. When the moisture content of the wood boards is found to be qualified, the thrust plate 903 rotates to be horizontal with the machine body 7, and then the wood boards are guided and transported away by the conveyor belt 6.

[0046] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described above, and the electrical connection should be completed by referring to the working sequence of each electrical component. The detailed connection methods are well-known technologies in the field. The above mainly introduces the working principle and process, and will not describe the electrical control.
