Description

Technical Field

[0001] This invention relates to the field of sheet material conveying technology, specifically to a reversing conveying device based on dust cover sheet material. Background Technology

[0002] In the processing of dust cover panels, in order to meet the requirements of multiple processes such as cutting, bending, punching, and surface treatment, the panels usually need to be transported in different directions multiple times. Therefore, a reversing device is often needed to transport the panels in different directions.

[0003] Existing sheet metal conveying lines are usually roller conveyors, which require disconnecting the roller conveyor to install a steering device. In other words, a steering device must be installed between two roller conveyors to achieve the steering of the sheet metal. This makes the conveying line structure more complex and makes it difficult to achieve continuous sheet metal conveying. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a reversing conveyor based on a dust cover plate, which solves the problem that setting a turning device between two roller conveyor mechanisms makes the conveyor line structure more complex.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a reversing conveying device based on dust cover sheet metal, comprising a frame of a roller conveyor and conveying rollers. A U-shaped bracket is fixedly connected to the upper surface of the frame, and a motor is fixedly connected to the center of the bracket. A reversing assembly is installed at the drive end of the motor. The reversing assembly includes an electric slide table (using a bidirectional screw electric slide table) and a lifting mechanism. Clamping plates are slidably connected to the lower sides of the electric slide table, and the clamping plates are positioned in the gaps of the conveying rollers. Inclined limiting plates are fixedly connected to the inner sidewalls of the clamping plates. An installation groove is provided on the inner bottom wall of the slider of the electric slide table, and an electric push cylinder is fixedly connected inside the installation groove. A connecting groove is provided on the upper surface of the clamping plates. The lifting mechanism is used to raise the height of the sheet metal relative to the conveying rollers, and the lower surface of the clamping plates is higher than the apex of the conveying rollers.

[0006] By adopting the above technical solution: the electric slide table drives two clamping plates to move simultaneously toward the plate, thereby clamping the plate by the cooperation of the clamping plates and limiting plates on both sides of the plate. Finally, the plate can be reversed by rotating 90° by the motor. Thus, only one roller conveyor mechanism is needed to transport the plate, simplifying the structure of the dust cover plate reversing conveyor line.

[0007] Preferably, the lifting mechanism includes a base plate, which is fixedly installed on the lower inner wall of the frame. A plurality of elastic telescopic support rods are fixedly connected to the upper surface of the base plate. A connecting plate is fixedly connected to the top of the elastic telescopic support rods.

An inclined surface is opened at one corner of the opposite side of the two extension plates.

[0008] Preferably, the lifting mechanism includes two extrusion members, the top of the extrusion members is slidably connected to the bottom of the electric slide table, the bottom of the extrusion members is fixedly provided with an extrusion wheel, and the upper surface of the extrusion members is provided with a connecting groove.

[0011] Preferably, a flipping assembly is installed inside the frame. The flipping assembly includes a second electric slide table, which is fixedly installed on the lower side wall of the frame. The slider of the second electric slide table is fixedly connected to a mounting platform. Several rotating frames distributed intersecting with the conveyor rollers are fixedly connected to the upper surface of the mounting platform. A rotating rod is rotatably connected to the upper side wall of the several rotating frames. Several flipping frames distributed intersecting with the conveyor rollers are fixedly connected to the outer side wall of the rotating rod. The flipping frames are U-shaped. Flipping mechanisms are respectively provided on both sides of the rotating rod. The flipping mechanisms are used to drive the rotating rod to rotate.

[0012] Preferably, the flipping mechanism includes a gear one, which is fixedly installed at one end of a rotating rod. A gear two is meshed with the upper side of the gear one. An extension rod is fixedly connected to the center of the gear two. The end of the extension rod near the gear two is rotatably connected to an adjacent flipping frame, and a gear three is fixedly connected to the end of the extension rod away from the gear two. The gear three is located in the gap of the conveying roller.

[0013] Preferably, the flipping mechanism includes a toothed plate, and a support plate is fixedly connected to the lower part of the toothed plate. Both ends of the support plate are fixedly connected to the inner sidewall of the frame. The toothed plate is located on the moving trajectory of the third gear and can mesh with the third gear. The length of the toothed plate is equal to half the circumference of the third gear, so that the third gear can rotate 180° when it rolls from one end to the other on the toothed plate.

[0014] Preferably, the side wall of the frame has a notch at the location corresponding to the movement trajectory of the tilting frame for the tilting frame to pass through the frame. The tilting frame includes a frame body, and an adjustment plate is provided inside the frame body. Two sliding plates are fixedly provided on the lower surface of the adjustment plate. The sliding plates pass through and are slidably connected to the frame body. A trapezoidal lifting platform is provided below the sliding plates. The lifting platform passes through and is fixedly connected to the frame.

[0015] Preferably, a plurality of electric telescopic rods are fixedly connected to the upper surface of the frame, and a pressure block is fixedly connected to the drive end of the electric telescopic rod. A pressure sensing module is fixedly installed on the lower surface of the pressure block.

[0016] Working principle: Before use, the electric slide table moves the slider to above the clamping plate, and the electric push cylinder extends to insert its drive end into the connecting groove, thus connecting the slider of the electric slide table to the clamping plate. The dust cover material is transported by a roller conveyor. When the material needs to be reversed, the roller conveyor transports the material to the bottom of the support. First, the lifting mechanism raises the height of the material to create a misalignment, preventing the material from colliding with the materials on the front and back sides during subsequent rotation, and allowing the clamping plate to be inserted under the material. The electric slide table then moves the two clamping plates simultaneously towards the material, where the clamping plates on both sides of the material and the limiting plate cooperate to clamp the material. Finally, the motor rotates the material 90° to reverse its direction. Thus, only one roller conveyor mechanism is needed to transport the material, simplifying the structure of the dust cover material reversing conveyor line.

[0017] This invention provides a reversing conveyor based on a dust cover plate. It has the following advantages:

[0018] 1. This invention uses clamping plates and limiting plates on both sides of the plate to clamp the plate. Then, the plate can be rotated 90° by a motor to change the direction of the plate. Thus, only one roller conveyor mechanism is needed to transport the plate, which simplifies the structure of the dust cover plate reversing conveyor line.

[0019] 2. The present invention uses the elastic force of the elastic telescopic support rod to make the top of the lifting plate higher than the conveying roller, thereby lifting the plate. The lifting plate disperses the weight of the plate, reduces the load on the clamping plate, and prevents the plate from falling onto the conveying roller and causing collisions due to the height difference when the clamping plate exits the plate.

[0020] 3. In this invention, the electric sliding table moves the mounting platform from one side of the frame to the other. Then, the rotating rod is driven to rotate by the flipping mechanism. The rotating rod drives the flipping frame to rotate 180 degrees, so that the plate can be flipped by the flipping frame. Thus, the flipping component can be integrated and installed on the roller conveyor without taking up extra space.

[0021] 4. When the electric slide table moves the mounting platform from one side to the other inside the frame, the rotating frame rotates 180° through the meshing transmission of gear three and toothed plate, achieving the effect of flipping the plate. Automatic flipping can be achieved without additional drive equipment, reducing costs. Attached Figure Description

[0035] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1:

[0037] Please see the appendix Figure 1 - Appendix Figure 4 This invention provides a reversing conveying device based on dust cover sheet material, including a frame 1 of a roller conveyor and a conveying roller 2. A U-shaped bracket 3 is fixedly connected to the upper surface of the frame 1. A motor 4 is fixedly connected to the center of the bracket 3. A reversing component 5 is installed on the drive end of the motor 4. The reversing component 5 includes an electric slide 51 with a bidirectional screw electric slide and a lifting mechanism 56. The drive end of the motor 4 is fixedly connected to the slide of the electric slide 51. Clamping plates 52 are slidably connected to the lower sides of the electric slide 51. The clamping plates 52 are set in the gap of the conveying roller 2. An inclined limiting plate 53 is fixedly connected to the inner side wall of the clamping plate 52. An installation groove is opened in the inner bottom wall of the slider of the electric slide 51. An electric push cylinder 55 is fixedly connected inside the installation groove. A connecting groove is opened on the upper surface of the clamping plate 52. The lifting mechanism 56 is used to raise the height of the sheet material. The lower surface of the clamping plate 52 is higher than the top of the conveying roller 2 to avoid collision between the clamping plate 52 and the conveying roller 2 during rotation.

[0038] Specifically, when the clamping plate 52 moves to abut against the sheet material, it cooperates with the inclined limiting plate 53, causing the side wall of the limiting plate 53 to abut against the upper edge of the sheet material, thereby clamping and fixing the sheet material from above and below. This method is suitable for sheet materials of various thicknesses. Before use, the electric slide table 51 is driven to move its slider above the clamping plate 52, and the electric push cylinder 55 extends to insert its drive end into the connecting groove, thus connecting the slider of the electric slide table 51 with the clamping plate 52. The dust cover sheet material is then transported by a roller conveyor. When it is necessary to change the direction of the sheet material, it is done by... The roller conveyor transports the sheet metal to the bottom of the support 3. First, the lifting mechanism 56 raises the height of the sheet metal to create a misalignment, preventing the sheet metal from colliding with the sheets on the front and back sides during subsequent rotation. This allows the clamping plates 52 to be inserted under the sheet metal. Then, the electric slide table 51 drives the two clamping plates 52 to move towards the sheet metal simultaneously. The clamping plates 52 on both sides of the sheet metal, together with the limiting plates 53, clamp the sheet metal. Finally, the motor 4 rotates the sheet metal 90° to change its direction. Thus, only one roller conveyor mechanism is needed to transport the sheet metal, simplifying the structure of the dust cover sheet metal reversing conveyor line.

[0039] Example 2:

[0040] Please see the appendix Figure 5 - Appendix Figure 6 This embodiment provides an alternative structure compared to Embodiment 1 described above:

[0041] The lifting mechanism 56 includes a base plate 561, which is fixedly installed on the lower inner wall of the frame 1. Several elastic telescopic support rods 562 are fixedly connected to the upper surface of the base plate 561. A connecting plate 563 is fixedly connected to the top of each elastic telescopic support rod 562. Several lifting plates 564 are fixedly installed on the upper surface of the connecting plate 563, located in the gaps between the conveying rollers 2. Extension plates 565 are fixedly connected to the two side edges of the upper surface of the connecting plate 563. An inclined surface is formed at one corner of each side of the two extension plates 565. When the connecting plate 563 is elastically supported by the elastic telescopic rod and presses against the conveying pipe, and when the top of the lifting plate 564 is at the same level as the inner bottom wall of the clamping plate 52, the lifting mechanism 56 includes two extrusion parts 57. The top of the extrusion part 57 is slidably connected to the bottom of the electric slide table 51. An extrusion wheel 59 is fixedly installed at the bottom of the extrusion part 57. A connecting groove 2 is opened on the upper surface of the extrusion part 57. A connecting column 54 is fixedly connected to the side wall of the extrusion part 57. A magnetic ring 58 is fixedly connected to the end of the connecting column 54 away from the extrusion part 57. The clamping plate 52 is made of ferromagnetic material.

[0042] Specifically, unlike Embodiment 1, before use, the electric slide table 51 drives the slider to move directly above the extruder 57. At this time, the electric push cylinder 55 extends and inserts into the interior of the connecting groove 2 without engaging with the connecting groove 1, so that the slider of the electric slide table 51 can drive the extruder 57 to move. Before the plate is conveyed through the support 3 and after the plate is turned, the electric slide table 51 moves the two sets of extruders 57 to the two side edges of the electric slide table 51 respectively. When the extruder 57 moves, it drives the extrusion roller 59 to move. The extrusion roller 59 moves along the inclined surface of the extension plate 565 until it reaches the top of the extension plate 565. During this process, the extrusion roller 59 pushes the extension plate 565 downward. The downward movement of the extension plate 565 drives the connecting plate 563 and the lifting plate 564 downward, so that the top of the lifting plate 564 is lower than the conveying roller 2, so that the plate can pass through. When the plate needs to be reversed, the electric slide table 51 is operated to make the two extruders 57 move towards the plate synchronously. The extrusion plate 564 moves upward, and the extension plate 565 is misaligned. The elastic force of the elastic telescopic support rod 562 pushes the connecting plate 563 upward. When the connecting plate 563 moves upward, the top of the lifting plate 564 is higher than the conveying roller 2, which can lift the plate. At this time, since the top of the lifting plate 564 is at the same level as the inner bottom wall of the clamping plate 52, the lifting plate 564 disperses the weight of the plate, reduces the load on the clamping plate 52, and supports the plate when the clamping plate 52 exits the plate. This prevents the plate from falling onto the conveying roller 2 due to the height difference when the clamping plate 52 exits the plate. At the same time, when the extrusion piece 57 moves, the connecting column 54 pushes the clamping plate 52 to move, so that the clamping plate 52 clamps the plate and reverses the direction with the help of the motor 4. After the reversal is completed, when the electric slide 51 drives the extrusion piece 57 to move away from the plate, the magnetic ring 58 attracts the column clamping plate 52, so that the clamping plate 52 exits the plate synchronously and moves with the extrusion piece 57.

[0043] Example 3:

[0044] Please see the appendix Figure 7 Based on Embodiment 2, since the centerline of the plate along the forward direction may be misaligned with the centerline of the roller conveyor during conveying, the lifting plate 564 cannot stably support the plate, causing the plate to tilt. Therefore, it is necessary to center-align the misaligned plate before switching. Thus, this embodiment adopts the following technical solution:

[0045] The extrusion component 57 includes a connecting body 571. A groove 572 is provided on the upper surface of the connecting body 571. A slide plate 573 is slidably connected inside the groove 572. Several elastic elements 574 are fixedly connected to the lower surface of the slide plate 573. One end of the elastic element 574 is fixedly connected to the inner bottom wall of the groove 572. Positioning posts 575 are fixedly connected to both sides of the upper surface of the slide plate 573. A locking hole seat 576 is provided on the outer side of the positioning post 575. The locking hole seat 576 is fixedly connected to the outer wall of the electric slide table 51. The connecting groove 2 is located at the slide plate 573.

[0046] Specifically, when the sheet metal needs to be aligned before the changeover, the extruder 57 is first moved onto the extension plate by the electric slide table 51, and the positioning post 575 is aligned with the locking hole seat 576. Then, the electric push cylinder 55 retracts to make its drive end exit the connecting groove 2. At this time, since the electric push cylinder 55 is no longer pressing the slide plate 573, the slide plate 573 slides upward under the elastic force of the elastic member 574, and the positioning post 575 moves upward and inserts into the locking hole seat 576, thereby limiting and fixing the extruder 57, so that the extruder 57 stably presses down on the extension plate 565. Then, the electric slide table 51 moves to drive the extension plate 565. The block moves above the clamping plate 52, and the electric push cylinder 55 extends and inserts into the connecting groove. At this time, the electric slide table 51 drives the clamping plate 52 to move and abut against the plate, thereby aligning the plate and preventing the lifting plate 564 from tilting and lifting the plate. After the plate is aligned, the electric push cylinder 55 retracts and moves back above the extruder 57 under the drive of the electric slide table 51, so that the electric push cylinder 55 extends and reconnects with the extruder 57. During subsequent clamping, the extruder 57 drives the connecting column 54 to push the clamping plate 52 against the plate, and the two are reconnected through the cooperation of the magnetic ring 58.

[0047] Example 4:

[0048] Please see the appendix Figure 8 - Appendix Figure 9 Based on the above embodiments, since the dustproof board material not only needs to be reversed during processing, but also needs to be flipped over for grinding and other operations, this embodiment adopts the following technical solution to flip the board material:

[0049] The frame 1 is equipped with a flipping assembly 6, which includes an electric slide table 61. The electric slide table 61 is fixedly installed on the lower side wall of the frame 1. The slider of the electric slide table 61 is fixedly connected to a mounting platform 62. Several rotating frames 63 are fixedly connected to the upper surface of the mounting platform 62, which are distributed intersectingly with the conveying roller 2. The upper side walls of the several rotating frames 63 are rotatably connected to a rotating rod 64. Several flipping frames 65 are fixedly connected to the outer side wall of the rotating rod 64, which are distributed intersectingly with the conveying roller 2. The flipping frame 65 is U-shaped. Flipping mechanisms 66 are respectively provided on both sides of the rotating rod 64. The flipping mechanisms 66 are used to drive the rotating rod 64 to rotate. When the flipping frame 65 is horizontal, its inner bottom wall is lower than the top of the conveying roller 2 so that the plate can be conveyed through the flipping frame 65.

[0050] Specifically, the lower side of the tilting frame 65 is kept horizontal by abutting against the rotating frame 63, allowing the sheet metal to pass through the tilting frame 65 during conveying. When the sheet metal needs to be tilted, it is conveyed into the tilting frame 65. The electric slide table 61 drives the mounting table 62 to move from one side to the other inside the frame 1. Then, the tilting mechanism 66 drives the rotating rod 64 to rotate, and the rotating rod 64 drives the tilting frame 65 to rotate 180 degrees. Thus, the sheet metal can be tilted through the tilting frame 65. Therefore, the tilting component 6 is integrated into the roller conveyor without occupying additional space, achieving the effect of simplifying the dust cover sheet metal reversing conveyor line.

[0051] Please see the appendix Figure 9 - Appendix Figure 12 The flipping mechanism 66 includes a gear 661, which is fixedly mounted on one end of a rotating rod 64. A gear 662 is meshed with the upper side of the gear 661. An extension rod 663 is fixedly connected to the center of the gear 662. The end of the extension rod 663 near the gear 662 is rotatably connected to an adjacent flipping frame 65, and a gear 664 is fixedly connected to the end of the extension rod 663 away from the gear 662. The gear 664 is located in the gap of the conveying roller 2. The flipping mechanism 66 also includes a toothed plate 665. A support plate 666 is fixedly connected to the lower part of the toothed plate 665. The two ends of the support plate 666 are fixedly connected to the inner side wall of the frame 1. The toothed plate 665 is located on the moving trajectory of the gear 3 664 and can mesh with the gear 3 664. The length of the toothed plate 665 is equal to half the circumference of the pitch circle of the gear 3 664, so that the gear 3 664 can rotate 180° when it rolls from one end to the other on the toothed plate 665. A notch is provided on the side wall of the frame 1 corresponding to the moving trajectory of the tilting frame 65 for the tilting frame 65 to pass through the frame 1.

[0052] Specifically, when the electric slide table 61 moves the mounting platform 62 from one side to the other inside the frame 1, the gear 664 moves and meshes with the toothed plate 665, generating forward rotation. When the gear 664 rotates, it drives the extension rod 663 to rotate, which in turn drives the gear 662 to rotate. The gear 662 then drives the gear 661 to rotate in the opposite direction, which in turn drives the rotating rod 64 to rotate. As the gear 664 rolls from one end to the other on the toothed plate 665, the rotating rod 64 causes the flipping frame 65 to rotate 180°, achieving the effect of flipping the plate. Automatic flipping can be achieved without additional drive equipment. When the electric slide table 61 moves in the opposite direction to return the mounting platform 62 to its original position, the flipping frame 65 flips 180° in the opposite direction when the gear 664 engages with the toothed plate 665, achieving the effect of reuse.

[0053] Example 5:

[0054] Please see the appendix Figure 12 Based on the above-described embodiment four, since it is necessary to control the inner bottom wall of the tilting frame 65 to be lower than the top of the conveying roller 2 so that the board can be conveyed through the tilting frame 65, and when the tilting frame 65 drives the board out of the frame 1, the lack of support at the bottom of the outer area of ​​the frame 1 due to the height difference between the inner bottom wall of the tilting frame 65 and the top of the conveying roller 2 can easily cause the board to tilt and slide out of the tilting frame 65. In order to solve the above-described technical problems, this embodiment adopts the following technical solution:

[0055] The tilting frame 65 includes a frame body 651. An adjusting plate 652 is provided inside the frame body 651. Two sliding plates 653 are fixedly provided on the lower surface of the adjusting plate 652. The sliding plates 653 pass through and are slidably connected to the frame body 651. A trapezoidal lifting platform 654 is provided below the sliding plates 653. The lifting platform 654 passes through and is fixedly connected to the frame 1. The height of the lifting platform 654 is the same as the distance between the upper surface of the adjusting plate 652 and the vertex of the conveying roller 2, so that when the sliding plate 653 lifts the plate, the upper surface of the sliding plate 653 and the vertex of the conveying roller 2 are on the same horizontal plane.

[0056] Specifically, before use, the electric slide table 61 drives the mounting table 62 from one side inside the frame 1. At this time, the lifting table 654 and the sliding plate 653 are misaligned. The bottom of the sliding plate 653 lacks support and slides downward, so that the height of the upper surface of the adjusting plate 652 is lower than the top of the conveying roller 2 so that the plate can be conveyed through. When the electric slide table 61 drives the mounting table 62 to move to the other side of the frame 1, the mounting table 62 drives the tilting frame 65 to pass through the notch into the frame 1. At this time, the bottom end of the sliding plate 653 moves horizontally and upward along the inclined surface of the lifting table 654, thereby pushing the adjusting plate 652 upward, so that the adjusting plate 652 supports the plate and keeps the plate horizontal when pushed by the frame 651. This avoids the problem that the plate is prone to tilting when it moves to the outer area of ​​the frame 1 due to lack of support at the bottom.

[0057] Please see the appendix Figure 12 Several electric telescopic rods 656 are fixedly connected to the upper surface of the frame 651. A pressure block is fixedly connected to the drive end of the electric telescopic rod 656. A pressure sensing module is fixedly installed on the lower surface of the pressure block. The pressure sensing module is electrically connected to a controller. The controller is electrically connected to the electric telescopic rod 656, the electric push cylinder 55, the electric slide table 1 51, the electric slide table 2 61 and the motor 4, and is used to control the electric telescopic rod 656, the electric push cylinder 55, the electric slide table 1 51, the electric slide table 2 61 and the motor 4.

[0058] Specifically, after the electric slide table 61 moves to lift the sliding plate 653, the electric telescopic rod 656 extends to press down the pressure block, thus fixing the plate. The pressure of the pressure block on the plate is detected by the pressure sensing module. When the tilting frame 65 rotates upward and the lifting table 654 no longer limits the sliding plate 653, causing a change in pressure, a signal is transmitted to the controller. The controller controls the electric telescopic rod 656 to extend and retract by a corresponding distance, so that the pressure block always applies a relatively stable compressive force to the plate. This allows the pressure block and the adjusting plate 652 to stably clamp the plate and prevent it from shaking when tilting. After tilting is completed, the electric telescopic rod 656 retracts.

[0059] Workflow: Before use, the electric slide table 51 moves the slider to directly above the extruder 57. At this time, the electric push cylinder 55 extends and inserts into the connecting groove 2, so that the slider of the electric slide table 51 can move the extruder 57. Before the sheet material is conveyed through the support 3 and after the sheet material is turned, the electric slide table 51 moves the two sets of extruders 57 to the two side edges of the electric slide table 51 respectively. When the extruder 57 moves, it drives the extrusion roller 59 to move. The extrusion roller 59 moves along the inclined surface of the extension plate 565 until it reaches the top of the extension plate 565. During this process, the extrusion roller 59 pushes the extension plate 565 downward. The downward movement of the extension plate 565 drives the connecting plate 563 and the lifting plate 564 downward, so that the top of the lifting plate 564 is lower than the conveying roller 2, so that the sheet material can pass through. When the sheet material needs to be reversed, the electric slide table 51 moves the two extruders... 57 moves synchronously towards the plate. At this time, the extrusion plate and the extension plate 565 are misaligned. The elastic force of the elastic telescopic support rod 562 pushes the connecting plate 563 upward. When the connecting plate 563 moves upward, the top of the lifting plate 564 is higher than the conveying roller 2, thus lifting the plate. Since the top of the lifting plate 564 is at the same level as the inner bottom wall of the clamping plate 52, the lifting plate 564 disperses the weight of the plate, reduces the load on the clamping plate 52, and allows the lifting plate 564 to support the plate when the clamping plate 52 exits the plate. This prevents the plate from falling onto the conveying roller 2 due to the height difference when the clamping plate 52 exits the plate. At the same time, when the extrusion part 57 moves, it pushes the clamping plate 52 to move through the connecting column 54, so that the clamping plate 52 clamps the plate and reverses the direction with the help of the motor 4. Thus, only one roller conveying mechanism is needed to transport the plate, simplifying the structure of the dust cover plate reversing conveyor line.

[0060] When the board needs to be flipped, the board is conveyed into the flipping frame 65. The electric slide table 61 drives the mounting platform 62 to move from one side to the other inside the frame 1. When the gear 664 moves, it meshes with the toothed plate 665 and rotates in the forward direction. When the gear 664 rotates, it drives the extension rod 663 to rotate. The extension rod 663 drives the gear 662 to rotate. The gear 662 drives the gear 661 to rotate in the reverse direction. The gear 661 drives the rotating rod 64 to rotate. When the gear 664 rolls from one end to the other on the toothed plate 665, the rotating rod 64 drives the flipping frame 65 to rotate 180°, achieving the effect of flipping the board. The flipping operation can also be achieved on a single roller conveyor, which simplifies the dust cover board reversing conveyor line and can achieve automatic flipping without additional drive equipment.

[0061] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
