Description

Technical Field

[0001] This utility model belongs to the technical field of wood panel processing equipment, specifically referring to a fiber debris metal screening and conveying device. Background Technology

[0002] In the manufacturing process of wood-based panels, breaking down the wood (e.g., into wood chips, fibers, or shavings) is a core pretreatment step. Its main function is to break down the original natural structure of the wood, allowing it to recombine into engineered wood panels with uniform, stable, and controllable properties. This allows for the full utilization of raw materials such as small-diameter timber, branches, and even recycled wood, improving resource utilization. By decomposing the wood into small units, then applying glue and hot-pressing, defects such as anisotropy and knots in natural wood can be eliminated, significantly improving the dimensional stability, uniformity, and mechanical strength of the panels.

[0003] In the manufacturing process of wood-based panels, removing metal impurities from wood fragments is crucial, as these foreign objects can damage subsequent processing equipment. Furthermore, if residual metal is pressed into the panel, it can disrupt the panel's structure and damage the customer's subsequent processing tools. Therefore, removing metal impurities from wood fragments is directly related to production safety and product quality.

[0004] Currently, by installing metal detectors on the conveyor belt for wood fragments, the conveyor belt stops when it detects metal foreign objects mixed in with the wood fragments. The metal foreign objects must be removed before the conveyor belt can resume operation. However, there are many wood fragments on the conveyor belt, and searching for metal foreign objects directly on the conveyor belt takes a long time, which greatly increases the downtime of the equipment and thus affects the overall production efficiency. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, the purpose of this utility model is to provide a fiber debris metal screening and conveying device to at least partially solve the problems mentioned in the background art.

[0006] The technical solution adopted by this utility model is as follows: This utility model proposes a fiber debris metal screening and conveying device, comprising: A first conveyor and a second conveyor, wherein the discharge end of the first conveyor is located directly above the second conveyor, and the first conveyor and the second conveyor are provided with a discharge gap in the height direction; A metal detector is installed below the discharge end of the first conveyor, and a detection channel is provided on the inner side of the metal detector. The second conveyor is provided with a first conveying direction and a second conveying direction. The first conveying direction of the second conveyor is consistent with the conveying direction of the first conveyor. A hopper is installed at one end of the second conveyor with the second conveying direction, and the hopper is located below the second conveyor.

[0007] Furthermore, an electromagnetic plate is installed inside the hopper, and the electromagnetic plate is arranged at an angle, with a material discharge gap provided between the lower inclined end of the electromagnetic plate and the inner wall of the hopper.

[0008] Furthermore, a vibration unit is installed at the bottom of the electromagnetic plate, and the vibration unit is configured to drive the electromagnetic plate to vibrate.

[0009] Furthermore, springs are installed at the four bottom corners of the electromagnetic plate, and the electromagnetic plate is movably connected to the interior of the hopper through the springs.

[0010] Furthermore, a support seat corresponding to the spring is installed on the inner wall of the hopper, and the spring is fixed on the support seat.

[0011] Furthermore, a mounting frame is provided in the material return gap, and the two ends of the mounting frame are respectively fixed to the first conveyor and the second conveyor, and the metal detector is fixed to the mounting frame. Beneficial effects

[0012] By setting up a first conveyor and a second conveyor, with the second conveyor configured to have two conveying directions, when the material contains metal, the first conveyor stops. At this time, the material containing metal falls onto the second conveyor, which transports the falling material to the hopper. Then, the first and second conveyors resume conveying. As the material is continuously conveyed, multiple batches of material containing metal are transported to the hopper for collection and then centrally sorted, eliminating the need for sorting on the conveyor line and shortening the downtime of the conveying equipment.

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0017] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.

[0018] Combination Figure 1 As shown, this utility model embodiment provides a fiber debris metal screening and conveying device, including a first conveyor 1, a second conveyor 2 and a metal detector 3.

[0019] The discharge end of the first conveyor 1 is located directly above the second conveyor 2, and the first conveyor 1 and the second conveyor 2 are provided with a discharge gap 101 in the height direction (e.g., Figure 3 As shown, the metal detector 3 is installed below the discharge end of the first conveyor 1, and a detection channel 301 is provided on the inner side of the metal detector 3. The length of the detection channel 301 is greater than the discharge width of the first conveyor 1.

[0020] In a specific embodiment, a mounting frame 11 is provided in the unloading gap 101. The two ends of the mounting frame 11 are respectively fixed on the first conveyor 1 and the second conveyor 2, and the metal detector 3 is fixed on the mounting frame 11.

[0021] The material is conveyed by the first conveyor 1 and falls onto the second conveyor 2 through the discharge end of the first conveyor 1. The second conveyor 2 continues to convey the material. When the material falls through the discharge end of the first conveyor 1, it can pass through the detection channel 301. At this time, the metal detector 3 can monitor in real time whether there is metal in the material. If there is metal, an alarm will be triggered.

[0022] Furthermore, the second conveyor 2 is provided with a first conveying direction and a second conveying direction. The first conveying direction of the second conveyor 2 is consistent with the conveying direction of the first conveyor 1. When there is no metal in the material, the conveying direction of the second conveyor 2 is consistent with the conveying direction of the first conveyor 1, that is, the second conveyor 2 conveys along the first conveying direction.

[0023] Combination Figure 2 and Figure 3 As shown, a hopper 4 is installed at one end of the second conveyor 2 in the second conveying direction, and the hopper 4 is located below the second conveyor 2. When the metal detector 3 detects that the falling material contains metal, the first conveyor 1 stops. At this time, the material containing metal falls onto the second conveyor 2. Then, the second conveyor 2 switches to conveying along the second conveying direction, that is, the second conveyor 2 conveys the material that has just fallen into the hopper 4. Then, the first conveyor 1 starts up, and the second conveyor 2 switches to conveying along the first conveying direction to continue conveying the material.

[0024] As materials are continuously transported, materials that have been repeatedly detected to contain metal are uniformly transported to the collection hopper 4 for collection. Then, the materials in the collection hopper 4 are transported to the sorting station for centralized sorting. Sorting is not required on the conveyor line, which shortens the downtime of the conveying equipment and allows the first conveyor 1 and the second conveyor 2 to quickly resume material transport.

[0025] It should be noted that the distance conveyed by the second conveyor 2 along the second conveying direction is sufficient to convey the metal-containing material into the hopper 4.

[0026] Combination Figure 4 As shown, an electromagnetic plate 5 is installed inside the hopper 4, and the electromagnetic plate 5 is arranged at an angle. A material drop gap 401 is provided between the lower inclined end of the electromagnetic plate 5 and the inner wall of the hopper 4. The metal-containing material conveyed by the second conveyor 2 first falls onto the electromagnetic plate 5. Under the action of the magnetic field of the electromagnetic plate 5, the magnetic metal is attracted to the electromagnetic plate 5, while the material and non-magnetic metal fall along the inclined electromagnetic plate 5 and fall into the hopper 4 through the material drop gap 401. Through the sorting of the electromagnetic plate 5, the magnetic metal can be separated to reduce the intensity of subsequent sorting work.

[0027] Furthermore, a vibration unit 6 is installed at the bottom of the electromagnetic plate 5. The vibration unit 6 is configured to drive the electromagnetic plate 5 to vibrate. Through the vibration of the electromagnetic plate 5, the material falling on the electromagnetic plate 5 can be evenly dispersed. The electromagnetic plate 5 can better attract magnetic metal, and under the action of vibration, the material can fall quickly to avoid material blockage.

[0028] Furthermore, springs 7 are installed at the four corners of the bottom of the electromagnetic plate 5. The electromagnetic plate 5 is movably connected to the inside of the hopper 4 through the springs 7. The springs 7 can absorb vibration, reduce the further transmission of vibration, and prevent the equipment from malfunctioning due to vibration.

[0029] In a specific embodiment, a support seat 8 corresponding to the spring 7 is installed on the inner wall of the hopper 4, and the spring 7 is fixed on the support seat 8.

[0030] The working principle of this utility model is as follows: Material is conveyed by the first conveyor 1 and falls onto the second conveyor 2 via the discharge end of the first conveyor 1. The second conveyor 2 continues to convey the material. When the material falls through the discharge end of the first conveyor 1, it can pass through the detection channel 301. At this time, the metal detector 3 can monitor whether there is metal in the material in real time. When the metal detector 3 detects that the falling material contains metal, the first conveyor 1 stops. At this time, the material containing metal falls onto the second conveyor 2. Then, the second conveyor 2 switches to... The material is conveyed along the second conveying direction, that is, the second conveyor 2 conveys the falling material into the hopper 4. Then, the first conveyor 1 is started, and the second conveyor 2 switches to conveying along the first conveying direction to continue conveying the material. As the material is continuously conveyed, the material that has been repeatedly detected to contain metal is uniformly conveyed to the hopper 4 for collection. Then, the material in the hopper 4 is conveyed to the sorting station for centralized sorting. There is no need to sort on the conveyor line, which shortens the downtime of the conveying equipment and allows the first conveyor 1 and the second conveyor 2 to quickly resume the conveying of materials.

[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0032] The embodiments have been described above, and such description is not restrictive. The figures shown are only one embodiment, and the actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit, such design should fall within the scope of protection.
