Description

Technical Field

[0001] This utility model relates to the field of plate screening technology, and in particular to a waste plate screening output buffer device. Background Technology

[0002] Post-processing of engineered wood panels refers to the procedures performed after panel manufacturing. It includes panel screening, cooling, and stacking. Currently, these processes are automated using conveyor systems, achieving a fully automated production line. The panel screening process is included because the manufactured panels may have defects in dimensions, thickness, deformation, etc. These defective panels, or waste panels, are prioritized for removal during post-processing. This removal is primarily achieved using an online screening device installed on the panel conveyor line. This device mainly includes a tilting and oscillating screening conveyor mechanism with a hinged end for receiving panels and a drive-lifting end. When no waste panels are detected upstream, the receiving end of the screening conveyor mechanism is flush with the conveyor line, and the panels are continuously conveyed normally. When waste panels are detected upstream, the receiving end of the screening conveyor mechanism is lifted, and the waste panels from upstream fall through the opening formed below, achieving waste panel removal.

[0003] The current standard practice for handling screened waste boards involves installing a lateral output mechanism below the screening and conveying mechanism. Waste boards fall onto this mechanism and are then output laterally. However, in actual operation, it has been found that due to the accelerated output of boards after upstream inspection, the conveying speed on the post-processing conveyor line is very high. The lateral output mechanism, upon receiving a waste board, utilizes the friction between the waste board's own weight and the lateral conveying mechanism to achieve lateral conveying. There is a significant time gap between the waste board settling on the lateral output mechanism and its complete output. The frequency of waste board descent is high, especially when two waste boards are detected consecutively. The rapid screening speed of the waste boards leads to situations where the previous waste board has not been fully output laterally before the next one has already fallen, resulting in partial overlap between the two waste boards. This overlap reflects a chaotic waste board posture, hindering smooth flow during subsequent transfers. Therefore, measures need to be taken to improve this situation. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a waste board screening output buffer device that can be adapted to high-frequency waste board screening for waste board reception, and promotes the independent and orderly output posture of waste boards, which is conducive to the smooth subsequent circulation of waste boards.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a waste board screening output buffer device, including a frame, on which two buffer platforms are installed above the lateral output mechanism. The two buffer platforms are used to temporarily support the screened waste boards. The two buffer platforms are movably arranged to move closer to or further away from each other in the lateral direction. Movable guide mechanisms are provided between the two buffer platforms and the frame, and opening and closing control devices are provided between the two buffer platforms and the frame.

[0006] As a preferred technical solution, the movable guide mechanism includes a support guide rail fixedly mounted on the frame and located at both ends of the buffer platform, and a support guide wheel that travels on the support guide rail on the corresponding side is respectively installed on both ends of the buffer platform.

[0007] As a preferred technical solution, anti-deviation guide rails are also fixedly provided at the ends of the buffer support on the frame, and anti-deviation guide wheel sets are respectively installed on the corresponding ends of the buffer support, which are clamped on the anti-deviation guide rails.

[0008] As a preferred technical solution, the opening and closing control device includes two opening and closing transmission wheels mounted on the frame, and an opening and closing transmission chain is mounted on both opening and closing transmission wheels. An opening and closing transmission seat connected to the corresponding opening and closing transmission chain is fixedly provided on the buffer support, and one of the opening and closing transmission wheels is connected to an opening and closing drive motor.

[0009] As a preferred technical solution, the opening and closing transmission wheel and the opening and closing transmission chain are respectively installed on the frame at both ends of the buffer platform. The two ends of the buffer platform are respectively fixed with opening and closing transmission seats connected to the opening and closing transmission chain on the corresponding side. A sprocket synchronous shaft is fixedly connected between the two opening and closing transmission wheels located on the far side of the two buffer platforms.

[0010] As a preferred technical solution, the buffer support is fixedly provided with a plate limiting stop.

[0011] Due to the adoption of the above technical solution, the waste board screening output buffer device includes a frame, on which two buffer platforms are installed above the lateral output mechanism. The two buffer platforms are used to temporarily support the screened waste boards. The two buffer platforms are movably arranged to move closer or further apart from each other in the lateral direction. Movable guide mechanisms are provided between the two buffer platforms and the frame, and an opening and closing control device is provided between the two buffer platforms and the frame. This utility model utilizes two openable and closable buffer platforms to temporarily support the screened waste boards. When there is continuous screening of waste boards, the two buffer platforms remain closed, allowing continuous reception of screened waste boards. However, if there is a short time interval between the screening of waste boards, such as when multiple qualified boards are detected between two adjacent waste boards, the two buffer platforms are driven by the opening and closing control device to quickly open, allowing the waste boards to fall directly onto the lateral output mechanism below. Then, the two buffer platforms are driven by the opening and closing control device to quickly close, continuing to receive subsequent screened waste boards. Therefore, the two buffer platforms act as buffers for the waste boards under screening, which can be adapted to high-frequency waste board screening for waste board reception. Moreover, the dropping action can be quickly achieved by the opening and closing of the two buffer platforms, which can be completed during the short time interval of waste board screening. Furthermore, the waste boards or stacks of waste boards fall directly and are not affected by the subsequent waste boards under screening above. They can be output by the lateral output mechanism in an independent and orderly manner, which is conducive to the smooth subsequent circulation of waste boards. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. 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 8 As shown in the figure, the waste board screening output buffer device includes a frame 1. The frame 1 can be a frame 1 shared with the online screening device 7 or the side output mechanism 8 of the waste board 9, or it can be a frame 1 set separately and kept relatively fixed to the frame of the online screening device 7 or the side output mechanism 8. No limitation is made here.

[0024] Two buffer platforms 2 are installed on the frame 1 above the lateral output mechanism 8. The two buffer platforms 2 are used to temporarily support the screened waste plates 9. The two buffer platforms 2 are movably arranged to be close to or far apart from each other in the lateral direction. Movable guide mechanisms 3 are respectively provided between the two buffer platforms 2 and the frame 1. Opening and closing control devices 4 are provided between the two buffer platforms 2 and the frame 1.

[0025] Under normal circumstances, such as Figures 1 to 4 as well as Figure 7As shown, the two buffer platforms 2 remain in a closed state. Here, "closed" means that the near edges of the two buffer platforms 2 are close together, allowing them to form a single platform for supporting the waste board 9. When a waste board 9 is screened out, it falls directly onto the closed buffer platforms 2 and is supported by them. Preferably, each buffer platform 2 is fixedly equipped with a board-limiting baffle 21 to block and limit the waste board 9 that is screened out at a certain speed, ensuring that the waste board 9 falling onto the buffer platform 2 remains in a basically fixed position each time. Figure 5 and Figure 8 As shown, after the two buffer supports 2 are opened by the opening and closing control device 4, the waste plate 9 falls freely due to the loss of its supporting function. Here, "opening" means that the two buffer supports 2 move away from each other until an opening is formed between them sufficient for the waste plate 9 to fall.

[0026] Based on the above principle, when there is continuous screening of waste boards 9, the two buffer platforms 2 remain closed and can continuously receive the screened waste boards 9; however, as long as there is a short time interval between the screening of waste boards 9, such as when multiple qualified boards are detected between two adjacent waste boards 9, the two buffer platforms 2 are driven by the opening and closing control device 4 to open quickly, and the waste boards 9 can fall directly onto the lower lateral output mechanism 8. Then, the two buffer platforms 2 are driven by the opening and closing control device 4 to close quickly and continue to receive the subsequent screened waste boards 9.

[0027] Thus, the two buffer platforms 2 serve as buffers for the screened waste plates 9, adapting to the high-frequency screening of waste plates 9 for waste plate 9 reception. Moreover, the dropping action can be quickly achieved by the opening and closing of the two buffer platforms 2, with a fast dropping speed that can be completed within the short time interval of the screened waste plates 9. Furthermore, the waste plates 9 or stacks of waste plates 9 on the buffer platforms 2 fall directly, and after falling, they are not affected by the subsequent screened waste plates 9 above. They can be output by the lateral output mechanism 8 in an independent and orderly manner, which is conducive to the smooth subsequent circulation of waste plates 9.

[0028] Among them, such as Figure 2 and Figure 4 As shown, the movable guide mechanism 3 in this embodiment includes support guide rails 31 fixedly mounted on the frame 1 and located at both ends of the buffer platform 2. Support guide wheels 32 are respectively installed on both ends of the buffer platform 2, traveling on the corresponding support guide rails 31. At least two support guide wheels 32 are installed at each support guide rail 31 to form a support and guide function. The movable guide mechanism 3 in this embodiment adopts a wheel-rail structure, resulting in low movement resistance and facilitating rapid opening and closing of the two buffer platforms 2.

[0029] More preferably, anti-deviation guide rails 33 are fixedly provided at the ends of the buffer platforms 2 on the frame 1, and anti-deviation guide wheel sets 34 are respectively installed on the corresponding ends of the buffer platforms 2, which are clamped on the anti-deviation guide rails 33. Of course, at least two anti-deviation guide wheel sets 34 are clamped on the anti-deviation guide rails 33 to form an anti-deviation guiding function. Through this anti-deviation guide, in conjunction with the aforementioned support guide, the two buffer platforms 2 are made to open and close quickly and smoothly.

[0030] like Figures 1 to 5 As shown, the opening and closing control device 4 in this embodiment includes two opening and closing transmission wheels 41 mounted on the frame 1. An opening and closing transmission chain 42 is mounted on both wheels 41. An opening and closing transmission seat 43, connected to the corresponding opening and closing transmission chain 42, is fixedly provided on the buffer platform 2. One of the opening and closing transmission wheels 41 is connected to an opening and closing drive motor 44. When the opening and closing drive motor 44 drives the opening and closing transmission wheel 41 to rotate, the opening and closing transmission chain 42 pulls the buffer platform 2 to move laterally. More specifically, when the opening and closing drive motor 44 drives in the forward direction, the buffer platform 2 opens; when the opening and closing drive motor 44 drives in the reverse direction, the buffer platform 2 closes.

[0031] This embodiment illustrates that each of the two buffer platforms 2 is equipped with an opening and closing control device 4. In actual installation, the two buffer platforms 2 can also share a single opening and closing control device 4. In this case, the opening and closing transmission seats 43 on the two buffer platforms 2 are fixedly connected to the upper and lower sections of the opening and closing transmission chain 42, respectively. Alternatively, the two buffer platforms 2 can also be driven to open and close by a drive cylinder.

[0032] Preferably, the opening and closing drive wheel 41 and the opening and closing drive chain 42 are respectively installed at both ends of the buffer platform 2 on the frame 1. Opening and closing drive seats 43, connected to the corresponding opening and closing drive chain 42, are fixedly provided at both ends of the buffer platform 2. A sprocket synchronous shaft 45 is fixedly connected between the two opening and closing drive wheels 41 located on the far sides of the two buffer platforms 2. Thus, for each buffer platform 2, the opening and closing control device 4 forms a synchronous opening and closing drive at both ends. This symmetrical opening and closing drive force also facilitates the smooth and rapid opening and closing of the buffer platform 2.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
