Description

Technical Field

[0001] This utility model relates to the field of adjustable width conveyor technology for single boards, and specifically to a single board adjustable width sorting device. Background Technology

[0002] In the sheet metal processing industry, after initial stacking, sheets typically need to be transferred to the unloading station via conveyor equipment for individual separation before subsequent sorting, stacking, or processing. Common unloading methods generally include the following steps: First, the entire stack of sheets is hoisted onto a conveyor, which then transports it to the unloading equipment. A lifting device is installed at the bottom of the equipment to lift the entire stack upwards. When the sheets reach a predetermined height, a hydraulic pusher on the side actuates, pushing the top layer of sheets outwards. The remaining sheets are temporarily held on the lifting device by a retaining structure. After that layer is pushed away, the lifting device rises again, thus separating the next sheet. This cycle continues until the unloading process is complete. However, existing material feeding equipment of this type still has significant limitations in practical applications. Because their main structure is mostly fixed, parameters such as lifting stroke, push plate position, and stop height are often not flexibly adjustable, resulting in the equipment only being suitable for feeding sheet metal of specific specifications (such as length, width, and thickness). Once the length and width of the sheet metal change significantly, problems such as the fixed-stroke hydraulic rod failing to fully push the sheet metal to the target station, or the sheet metal tilting or being damaged due to uneven force during pushing, can easily occur, severely affecting feeding efficiency and reliability.

[0014] To address the technical problems in the background art, the following is provided: a single-board adjustable width sorting device: Combination Figures 1-10As shown, the present invention provides a single-board adjustable width sorting device, including a separation box 100. A conveying component 200 is installed on the upper part of the inner cavity of the separation box 100, a lifting component 300 is installed on the lower part of the inner cavity of the separation box 100, a baffle 400 is fixedly connected to the lower part of the inner cavity of the separation box 100, a feeding component 500 is installed at one end of the separation box 100, and a discharging component 600 is installed at the other end of the separation box 100. The conveying component 200 includes a long plate 201 and a transmission rod 202. The long plate 201 is fixedly connected to the upper part of the inner cavity of the separation box 100, a conveying motor 203 is fixedly connected to one end of the bottom surface of the long plate 201, and the transmission rod 202 is rotatably connected to the upper part of the inner cavity of the separation box 100. The output end of the conveying motor 203 is rotatably connected to the transmission rod 202 through a sprocket set and a chain. A sliding groove 204 is opened on the surface of the transmission rod 202, and conveying components are symmetrically installed on the surface of the transmission rod 202.

[0015] The conveying motor 203 in the conveying assembly 200 drives the transmission rod 202 to rotate, thereby driving the rotation of the two sets of conveying components, thus realizing the conveying of the sheet metal.

[0016] In this embodiment, the feeding component includes a dial 205, the dial 205 is slidably connected to the surface of the transmission rod 202, a pawl 206 is fixedly connected to one side of the dial 205, a sliding block 207 is fixedly connected to the middle of the dial 205, the sliding block 207 slides in the sliding groove 204, and a C-shaped elastic ring 208 is fixedly connected to the middle of one side of the dial 205. The crack of the C-shaped elastic ring 208 is connected by a locking bolt 209.

[0017] With the cooperation of "sliding block + sliding groove", the dial can slide smoothly along the axis of the transmission rod, driving the pawl to move synchronously, realizing the adjustment of the distance between the two sets of feeding components, which can cover the feeding needs of "plates of different widths within a certain range".

[0018] In this embodiment, the lifting assembly 300 includes a self-locking motor 301, a lifting rod 302, and an auxiliary lifting sprocket 303. The lifting rod 302 is rotatably connected to both ends of the upper part of the inner cavity of the separation box 100. The self-locking motor 301 is fixedly connected to the other end of the top surface of the long plate 201.

The non-powered rollers 307 are rotatably connected at equal intervals in the middle of the lifting frame 306.

[0019] Through the transmission structure of "self-locking motor + lifting rod + lifting sprocket + lifting chain", when the self-locking motor is working, it drives the lifting rod to rotate through the sprocket group. The lifting rod drives the lifting sprockets at both ends to rotate synchronously. Then, through the cooperation of the lifting chain and the auxiliary lifting sprocket, the lifting frame is driven to rise and fall smoothly along the inner cavity of the separation box, ensuring that the sheet can contact the claw of the conveying component, which facilitates the conveying of the sheet one by one in the later stage.

[0020] In this embodiment, the feeding assembly 500 includes a feeding frame 501, with conveying rollers 502 rotatably connected at equal intervals in the middle of the feeding frame 501. Side frames 503 are fixedly connected to both ends of the top surface of the feeding frame 501, and side limiting rollers 504 are rotatably connected to the inner side of the side frames 503. A feeding motor 505 is fixedly connected to the lower part of the feeding frame 501. The output end of the feeding motor 505 is rotatably connected to one of the conveying rollers 502 through a sprocket set and a chain. Every two conveying rollers 502 are rotatably connected through a sprocket set and a chain.

[0021] By using the "side limiting rollers" on the side frames at both ends of the feeding rack, a "guide channel" can be formed from both sides of the board to prevent the board from shifting to the sides during conveying and ensure that the board slides accurately onto the unpowered rollers of the lifting frame.

[0022] In this embodiment, the discharge assembly 600 includes a protective box 601 and a conveyor frame 602. One end of the conveyor frame 602 is fixed inside the protective box 601. An auxiliary discharge component is installed on one end of the top surface of the conveyor frame 602. A main roller 603 and a driven roller 604 are rotatably connected to the top surface of the conveyor frame 602 and to one side of the auxiliary discharge component. The surface of the main roller 603 is rotatably connected to the driven roller 604 via a conveyor belt 605. A drive motor 606 is fixedly connected to the bottom surface of the conveyor frame 602. The output end of the drive motor 606 is rotatably connected to the main roller 603 via a sprocket assembly and a chain.

[0023] By cooperating with the main roller 603, the driven roller 604, the drive motor 606, and the conveyor belt 605 in the discharge assembly, a complete conveyor is formed, which can realize the long-distance conveying of the sheet material.

[0024] In this embodiment, the auxiliary discharge component includes a first motor 607, a height frame 608, and a first opposing roller 609. The first opposing roller 609 is rotatably connected to the top surface of the conveyor frame 602, and the first motor 607 is fixedly connected to the bottom surface of the conveyor frame 602. The output end of the first motor 607 is rotatably connected to the first opposing roller 609 via a sprocket set and a chain. The height frame 608 is fixedly connected to the top surface of the conveyor frame 602. The height frame 608 is threadedly connected to a height threaded rod 610. One end of the height threaded rod 610 is rotatably connected to a U-shaped frame 611. A second opposing roller 612 is rotatably connected inside the U-shaped frame 611. A second motor 613 is fixedly connected to one side of the U-shaped frame 611. The output shaft end of the second motor 613 is rotatably connected to the second opposing roller 612 via a worm gear and a worm wheel. Slide rails 614 are symmetrically fixedly connected to the inner wall of the height frame 608, and the U-shaped frame 611 is slidably connected to the surface of the slide rails 614.

[0025] The structure of "height threaded rod + U-shaped frame + slide rail" allows the U-shaped frame to move up and down along the slide rail when the height threaded rod is rotated (corresponding to "height threaded rod adjusting the height of the second opposing roller" during operation), thereby adjusting the "spacing between the first opposing roller and the second opposing roller". This allows it to adapt to plates of different thicknesses and avoids problems such as jamming of thick plates and slippage of thin plates.

[0026] Working principle and usage process of this utility model: In use: During preparation, the staff first adjusts the spacing between the two sets of conveying components according to the width of the sheet material to be conveyed. During adjustment, the locking bolt 209 is tightened first. As the locking bolt 209 rotates, the opening in the C-shaped elastic ring 208 widens, and the C-shaped elastic ring 208 no longer clamps the surface of the transmission rod 202. At this point, the staff can move the dial 205, allowing it to slide on the surface of the transmission rod 204. The movement of the dial 205 will drive the sliding block 207, the pawl 206, and the C-shaped elastic ring 208 to move respectively. When the sliding block 207 moves, it will slide within the sliding groove 204. When the two sets of conveying components move to the appropriate position, the locking bolt 209 is tightened again, causing the C-shaped elastic ring 208 to deform and clamp onto the surface of the transmission rod 202. This achieves the adjustment of the spacing between the two sets of conveying components, facilitating the conveying of sheet materials of different widths within a certain range later.

[0027] During operation, workers use an external crane to lift the stacked boards onto the conveyor roller 502. At this time, the feeding motor 505 is started. When the feeding motor 505 is working, it will drive the conveyor roller 502 to rotate. When the conveyor roller 502 rotates, it will move the upper board into the separation box 100. As the board moves forward, the side limiting roller 504 will limit the two sides of the board, so that the board moves forward in a straight line and moves from the conveyor frame 501 to the lifting frame 306 and is located on the non-powered roller 307. At the same time, one end of the board will also come into contact with the baffle 400 and stop moving forward. At this time, the self-locking motor 301 is started. When the self-locking motor 301 is working, it will drive the lifting rod 302 to rotate through the sprocket set and chain. When the lifting rod 302 rotates, it will drive the lifting sprocket 304 to rotate. When the lifting sprocket 304 rotates, it will drive the lifting chain 305 to rotate under the action of the auxiliary lifting sprocket 303. The rotation of the lifting chain 305 will drive the lifting frame 306 to move upward, thereby lifting the upper plate. When the uppermost plate contacts the pawl 206, the shifting motor 203 is started. When the shifting motor 203 is working, it will drive the transmission rod 202 to rotate under the action of the sprocket set and chain. When the transmission rod 202 rotates, it will drive the two sets of dials 205 to rotate. When the dials 205 rotate, they will drive the lifting frame 306 to move upward. The claw 206 rotates, and when the claw 206 rotates, it begins to convey the upper layer of material between the first opposing roller 609 and the second opposing roller 612. When the material enters between the first opposing roller 609 and the second opposing roller 612, the first motor 607 and the second motor 613 are started respectively. When the first motor 607 and the second motor 613 are working, they drive the first opposing roller 609 and the second opposing roller 612 to rotate in opposite directions, thereby conveying the material onto the conveyor belt 605. At this time, the drive motor 606 drives the main roller 603 to rotate, thereby driving the conveyor belt 605 to rotate under the action of the driven roller 604. When the conveyor belt 605 rotates, it begins to convey the material on the conveyor belt 605 to the external sorting equipment for subsequent sorting work.
