Description

Technical Field

[0001] This utility model relates to an online detection device, specifically an online detection device for metallic foreign objects in the recycling of waste wood resources, belonging to the technical field of detection devices. Background Technology

[0002] Removing metallic foreign objects during the recycling of waste wood resources is crucial because their presence poses a serious threat to subsequent processing stages and the quality of the final product. For example, metallic foreign objects (such as nails, wires, and metal fragments) are highly hard. If mixed into wood crushing and pulverizing processes, they can directly wear down or damage critical components like the blades and bearings of crushers and pulverizers, leading to frequent equipment failures, increased maintenance costs, extended downtime, and reduced production efficiency. If metallic foreign objects remain in recycled boards or biomass fuels, they can cause surface bulges, cracks, or blockages in combustion equipment, reducing product quality and even posing safety hazards. Therefore, removing metallic foreign objects is a necessary step to ensure the safe operation of processing equipment, improve the quality of recycled products, and ensure the efficient recycling of waste wood resources.

[0003] In the early stages of waste wood resource recycling, it is usually necessary to detect metallic foreign objects in the waste wood resources to ensure the safe and stable operation of processing equipment. However, due to the wide range of sources and diverse types of waste wood resources, including old furniture, flooring, and construction templates, as well as significant differences in size and specifications, ranging from small wood chips and scraps to furniture parts, most existing metal foreign object detection devices on the market are designed based on standard-sized conveyor channels and detection probes. When dealing with waste wood resources that are large in height and irregular in shape, they often encounter problems such as difficulty in smoothly passing through the detection area and easy jamming, thus affecting the detection efficiency. Therefore, an online metal foreign object detection device for waste wood resource recycling is proposed. Utility Model Content

[0004] In view of this, the present invention provides an online detection device for metal foreign objects in the recycling of waste wood resources, so as to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

[0005] The technical solution of this utility model embodiment is implemented as follows: an online detection device for metal foreign objects in the recycling of waste wood resources, including a conveyor, wherein a lifting component is installed on the frame of the conveyor; The lifting assembly includes a detection frame, two lifting plates, four sliders, a drive motor, a support plate, two support frames, a lead screw, two bases, and four guide rails. The slider is symmetrically and fixedly connected to the inner wall of the testing frame, the four guide rails are symmetrically and fixedly connected to the outer walls of the two support frames, the support plate is fixedly connected to one side of the support frame, the top end of the lead screw is fixedly connected to the output shaft of the drive motor, the two lifting plates are symmetrically and fixedly connected to the bottom of the outer wall of the testing frame, the two support frames are symmetrically and fixedly connected to the upper surface of the two bases, and the testing frame is located outside the two support frames.

[0006] More preferably, the inner wall of the detection frame is attached to the outer wall of the support frame, and the slider is slidably connected to the inner wall of the guide rail.

[0007] More preferably, the drive motor is mounted on the upper surface of the support plate, and the lifting plate is threadedly connected to the outer wall of the lead screw.

[0008] More preferably, the bottom end of the lead screw is rotatably connected to the upper surface of the base.

[0010] More preferably, the outer side wall of the testing frame has two symmetrical sliding grooves, and the support plate is slidably connected to the inner side wall of the sliding grooves.

Under the detection of an X-ray transmitter and receiver, metallic foreign objects can be displayed in the image. During the inspection process, a recognition camera monitors the height of the waste wood resources in real time. When the height of the waste wood resources exceeds the rated value, the control module controls the drive motor to work, thereby raising the position of the inspection frame so that the waste wood resources can enter the inspection frame.

Detailed Implementation

[0018] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0019] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0020] like Figures 1-5 As shown, this utility model embodiment provides an online detection device for metal foreign objects in the recycling of waste wood resources, including a conveyor 31, and a lifting assembly 101 is installed on the frame of the conveyor 31; The lifting assembly 101 includes a detection frame 11, two lifting plates 13, four sliders 14, a drive motor 15, a support plate 16, two support frames 17, a lead screw 18, two bases 19, and four guide rails 20. The slider 14 is symmetrically fixed to the inner wall of the testing frame 11, and the four guide rails 20 are symmetrically fixed to the outer walls of the two support frames 17. The inner wall of the testing frame 11 is attached to the outer wall of the support frame 17, and the slider 14 is slidably connected to the inner wall of the guide rail 20. When the testing frame 11 moves up or down, it rises and falls vertically under the guidance of the guide rail 20. Moreover, under the limiting action of the guide rail 20 and the slider 14, the testing frame 11 can be prevented from falling off the support frame 17, thus ensuring the stability of the structure. The support plate 16 is fixedly connected to one side of the support frame 17. The top end of the lead screw 18 is fixedly connected to the output shaft of the drive motor 15. The drive motor 15 is mounted on the upper surface of the support plate 16. The lifting plate 13 is threadedly connected to the outer side wall of the lead screw 18. The bottom end of the lead screw 18 is rotatably connected to the upper surface of the base 19. The support plate 16 can support the drive motor 15, ensuring the stability of the drive motor 15. When the drive motor 15 is working, the drive motor 15 drives the lead screw 18 to rotate. Two lifting plates 13 are symmetrically fixed to the bottom of the outer wall of the inspection frame 11, and two support frames 17 are symmetrically fixed to the upper surface of the two bases 19. The inspection frame 11 is located outside the two support frames 17. The drive motor 15 drives the lead screw 18 to rotate, and the lead screw 18 drives the lifting plate 13 through the thread. The lifting plate 13 drives the inspection frame 11 to move upward. The inspection frame 11 slides along the guide rail 20, thereby raising the position of the inspection frame 11 so that waste wood resources with large dimensions can pass through the inspection area smoothly without jamming or blocking, thus improving the inspection efficiency.

[0021] In one embodiment, two bases 19 are symmetrically installed on the upper surface of the frame of the conveyor 31, and two grooves 12 are symmetrically opened on the outer side wall of the detection frame 11. The support plate 16 is slidably connected to the inner side wall of the groove 12, and the position of the support plate 16 can be avoided through the groove 12.

[0022] In one embodiment, a recognition camera 22 is installed on the front surface of the detection frame 11, an X-ray transmitter 23 is installed on the inner top wall of the detection frame 11, and an X-ray receiver adapted to the X-ray transmitter 23 is installed inside the frame of the conveyor 31, thereby enabling online detection of metallic foreign objects in waste wood resources. The detection principle is as follows: when X-rays penetrate wood, the difference in absorption rate between the metal foreign object and the wood causes the metal foreign object to be detected. Then, the internal imaging sensor generates a grayscale image, which can then identify the metal foreign object in the image. The image is displayed on the screen 32. A display screen 32 is installed on the outer wall of the frame of the conveyor 31. During the inspection process, the inspection screen is displayed on the display screen 32. The identification camera 22 is used to detect the height of the waste wood resources in real time. When the height of the waste wood resources exceeds the rated value, the identification camera 22 sends a control signal to the control module, which then controls the drive motor 15 to adjust the position of the detection frame 11. Specifically: The identification camera 22 uses an integrated laser ranging algorithm to calculate the vertical distance between the waste wood resource and the reference plane of the identification camera 22 in real time, and compares it with a preset rated height threshold. When the height of the waste wood resource exceeds the threshold, the microprocessor built into the identification camera 22 encodes the height deviation value into a control signal (such as a PWM pulse or CAN bus protocol instruction), and transmits it to the control module through the signal terminal. The control module analyzes the direction and magnitude of the deviation based on the received signal, and controls the drive motor 15 to rotate precisely. The control module is a single-chip microcomputer and is installed in the detection frame 11. In this utility model, the identification camera 22, drive motor 15, X-ray transmitter 23, conveyor 31, and display screen 32 are all existing technologies, so their working principles, internal structures, and connection control methods will not be described in detail.

[0023] In operation, the waste wood resources are placed on the conveyor 31, which transports them to the area below the inspection frame 11. Under the detection of the X-ray transmitter 23 and the X-ray receiver, the X-rays penetrate the wood. Due to the difference in the absorption rate of X-rays between the metal foreign object and the wood, the metal foreign object can be displayed in the image. During the inspection process, the identification camera 22 detects the height of the waste wood resources in real time. When the height of the waste wood resources exceeds the rated value, the control module controls the drive motor 15 to work. The drive motor 15 drives the lead screw 18 to rotate, and the lead screw 18 drives the lifting plate 13 through the thread. The lifting plate 13 drives the inspection frame 11 to move upward. The inspection frame 11 slides along the guide rail 20, thereby raising the position of the inspection frame 11 so that the waste wood resources can enter the inspection frame 11. Compared with the prior art, this utility model, by setting up a lifting component 101, can automatically adjust the height of the inspection frame 11 during the inspection process, so that waste wood resources with larger dimensions can pass through the inspection area smoothly without jamming or blocking, thus improving inspection efficiency.

[0024] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
