Description

Technical Field

[0001] This utility model relates to the technical field of equipment for the production of engineered wood panels, and in particular to an online waste board screening device. Background Technology

[0002] Engineered wood products are made from wood or other non-wood plant materials, which are mechanically processed into various unit materials and then bonded together with or without adhesives and other additives. The process generally involves cutting, drying, gluing, and molding. Molded panels are typically automatically conveyed out using a conveyor system. Because engineered wood products require hot pressing, unevenness can easily occur due to inconsistent mixing of materials, uneven stress during hot pressing, and inconsistent cooling rates. This unevenness can severely impact the quality and lifespan of the panels. Panels that are deemed substandard due to other factors also need to be promptly screened and removed to ensure product quality. Traditionally, substandard panels are manually inspected and then moved to designated areas by multiple people for centralized processing. However, this method suffers from drawbacks such as untimely transfer, low efficiency, and high labor intensity. Utility Model Content

Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0023] like Figures 1 to 7 As shown, the waste board online screening device is installed on the artificial board conveyor line 1. It is used to select unqualified waste boards while conveying the hot-pressed artificial boards and automatically remove them from the line. Generally, a forklift 2 is provided below the device to receive and collect the waste boards, so as to facilitate the periodic recycling of waste boards by means of transport tools such as forklifts, realizing the centralized transfer and processing of waste boards, which is more convenient and labor-saving.

[0024] The waste board online screening device includes a support base frame 3, which is a steel structure frame with legs. The fork frame 2 for collecting waste boards is located below the support base frame 3. The fork frame 2 can be configured as a lifting frame, which can increase the amount of waste boards collected and transferred at one time, thereby reducing the transfer frequency of waste boards and improving the transfer efficiency.

[0025] A sheet metal conveyor frame 4 is mounted on the support base 3. A lifting support frame 5 spans the feed end of the sheet metal conveyor frame 4. The lifting support frame 5 is located above the sheet metal conveyor frame 4 and is mounted on the support base 3. A lifting power device for lifting the feed end of the sheet metal conveyor frame 4 is mounted on the lifting support frame 5. The lifting power device is driven by the sheet metal conveyor frame 4. The discharge end of the sheet metal conveyor frame 4 is rotatably mounted on the support base 3. With the drive of the lifting power device and the rotatable mounting of the discharge end of the sheet metal conveyor frame 4, the feed end of the sheet metal conveyor frame 4 can be lifted, forming a gap between it and the support base 3 to facilitate the unloading of waste sheets. When the board material on the artificial board conveyor line 1 in front of the support base 3 is detected as waste board by manual or electronic means, the lifting power device can be started manually or automatically to lift the feeding end of the lifting support frame 5 to form a gap between it and the support base 3, so that the waste board is automatically transferred to the fork 2 under the conveying of the artificial board conveyor line 1; after the waste board is transferred, the feeding end of the lifting support frame 5 is lowered to a horizontal state by the lifting power device, and qualified boards can continue to be conveyed, thereby avoiding manual handling, reducing labor intensity, reducing human intervention in the waste board transfer process, and making it convenient and labor-saving to use.

[0026] The lifting power device includes a lifting power shaft 6 rotatably mounted on the lifting support frame 5 and a lifting drive motor 7 fixedly mounted on the lifting support frame 5. The lifting power shaft 6 is located above the plate conveying frame 4 and is driveably connected to the lifting drive motor 7. A lifting arm 8 is fixedly connected to the lifting power shaft 6, and a lifting rod 9 is rotatably mounted between the lifting arm 8 and the plate conveying frame 4. In this embodiment, the lifting drive motor 7 is located in the middle of the lifting support frame 5, and there are two lifting power shafts 6 extending outward from the plate conveying frame 4. Alternatively, the lifting power shaft 6 can be a single long shaft traversing the top of the lifting support frame 5, rotatably supported on the lifting support frame 5. The outer ends of each lifting power shaft 6 are respectively fixedly connected to the upper ends of the lifting arms 8, and the lifting rod 9 is connected to the lower ends of the corresponding lifting arms 8. When the lifting drive motor 7 drives the lifting power shaft 6 to rotate, the feeding end of the plate conveying frame 4 is lifted by the cooperation of the lifting arm 8 and the lifting rod 9; the lifting drive motor 7 rotates in the opposite direction to lower the feeding end of the plate conveying frame 4.

[0027] The sheet metal conveying frame 4 in this embodiment includes a conveying frame body 41 with its discharge end rotatably assembled to the supporting base 3. Sheet metal conveyor belts 42 are evenly distributed on the conveying frame body 41. The feed end of each sheet metal conveyor belt 42 is rotatably assembled to the conveying frame body 41, and the discharge end of each sheet metal conveyor belt 42 is rotatably assembled to the supporting base 3. A roller body is provided at the feed end of the conveying frame body 41 corresponding to each sheet metal conveyor belt 42 for cooperative use. A conveyor belt roller 43 is rotatably mounted on the supporting base 3 at the discharge end of the conveying frame body 41. The discharge ends of each sheet metal conveyor belt 42 are fitted onto the conveyor belt roller 43. A conveyor belt motor 44, which is drively connected to the conveyor belt roller 43, is also fixedly mounted on the supporting base 3. The conveyor belt motor 44 drives the conveyor belt roller 43 to rotate, cooperating with the roller body at the feed end to drive the sheet metal conveyor belt 42, thereby conveying qualified sheet metal horizontally.

[0028] The supporting base 3 is equipped with a discharge power device at the discharge end of the sheet material conveying frame 4. An inclined discharge transition frame 10 is installed on the supporting base 3 behind the discharge power device, and a discharge lifting device is provided on the supporting base 3 between the discharge power device and the discharge transition frame 10. The discharge power device assists in discharge. When the infeed end of the sheet material conveying frame 4 lifts to remove waste sheet material, qualified sheet material is simultaneously being conveyed outwards from the top of the sheet material conveying frame 4. Due to the lifting of the infeed end of the sheet material conveying frame 4, its discharge end will appropriately lower, causing its discharge position to decrease. The discharge lifting device can be used to appropriately raise the discharge position to achieve the proper discharge height, thereby ensuring that the qualified sheet material being conveyed can be discharged smoothly.

[0029] Specifically, the discharge power unit includes a discharge support beam 11 spanning the support base 3, a discharge pressure roller 12 mounted on the discharge support beam 11, and a discharge idler roller 13 below the discharge pressure roller 12 for cooperative use. The discharge idler roller 13 is driven by a discharge motor 14. Driven by the discharge motor 14, the qualified sheet metal is conveyed outward through the cooperation of the discharge idler roller 13 and the discharge pressure rollers 12, thus realizing the discharge of this embodiment.

[0030] The discharge lifting device includes lifting drive plates 15 connected to both ends of the discharge support beam 11 and the support base 3, respectively. The two lifting drive plates 15 are rotatably connected to the support base 3. Lifting drive cylinders 16 are rotatably mounted between the two lifting drive plates 15 and the support base 3. The discharge roller 13 is rotatably installed between the two lifting drive plates 15. Each lifting drive plate 15 is an inverted T-shaped plate, with its front end rotatably connected to the support base 3 and the discharge roller 13 mounted at its rear end. The lifting drive cylinders 16 start synchronously with the lifting power device. After the two lifting drive cylinders 16 extend, they rotate the two lifting drive plates 15 towards the feed end of the support base 3, allowing the discharge roller 13 and the discharge pressure roller 12 to be lifted to a certain extent, facilitating the smooth clamping and discharge of the sheet material. The lifting drive cylinders 16 can be electric cylinders or hydraulic cylinders.
