Description

Technical Field

[0001] This utility model relates to the field of sheet material palletizing technology, and more specifically, to an automatic palletizing device for SMC sheets. Background Technology

[0002] In the production and processing of SMC sheets, the palletizing process is a crucial step connecting sheet production with subsequent warehousing and transportation. Its operational efficiency and stability directly affect the overall production process and the product quality of the SMC sheets. With the continuous expansion of SMC sheet applications, the market demand for SMC sheets of different widths and specifications is becoming increasingly diversified.

[0003] Traditional SMC sheet palletizing devices are prone to problems such as conveying deviation and jamming when dealing with SMC sheets of different widths on the conveyor frame. Since SMC sheets have a certain rigidity and their surface needs to be kept flat, once deviation occurs during the conveying process, it will not only lead to inaccurate subsequent palletizing positions and affect the neatness of the stack, but may also cause scratches or damage to the surface of the sheet due to friction and collision with the edge of the conveyor frame, reducing the product qualification rate. To address this, an automatic palletizing device for SMC sheets has been designed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides an automatic palletizing device for SMC boards, which has the advantage of improving palletizing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic palletizing device for SMC sheets, comprising a workbench, two symmetrically arranged conveyor frames connected to the top of the workbench, a support plate fixedly connected to the bottom of the conveyor frames, a first cylinder fixedly connected to the top of the support plate, a lifting plate fixedly connected to the top of the first cylinder, a correction plate fixedly connected to the bottom of an adjusting rod, a transport bracket fixedly connected to the upper surface of the workbench, a horizontal guide rail fixedly connected to the top of the transport bracket, a lifting slide frame slidably connected to the bottom of the horizontal guide rail, a sliding frame slidably connected to the inner wall of the transport bracket, a second cylinder fixedly connected to the lower surface of the inner wall of the sliding frame, the output end of the second cylinder fixedly connected to the top of the lifting slide frame, a bidirectional threaded rod rotatably connected to the inner wall of the lifting slide frame, and two sliding plates symmetrically threaded to the outer wall of the bidirectional threaded rod.

[0006] As a preferred embodiment of this utility model, the conveyor frame is rotatably connected with conveyor rollers, and a support bearing is symmetrically fixedly connected to one end of the conveyor frame near the lifting plate. The inner wall of the support bearing is rotatably connected to the outer wall of the adjusting rod.

[0007] As a preferred embodiment of this utility model, a correction plate is fixedly connected to the top end of the adjusting rod, a worm gear is fixedly connected to the bottom end of the adjusting rod, and a rotating shaft is rotatably connected to the conveyor frame.

[0008] As a preferred embodiment of this utility model, two worm gears are symmetrically fixedly connected to the outer wall of the rotating shaft. The worm gears mesh with a worm wheel. One end of the rotating shaft extends out of the outer wall of the conveyor frame, and a turntable is fixedly connected to the extended end of the rotating shaft.

[0009] As a preferred embodiment of this utility model, two limiting frames are symmetrically fixedly connected to the top of the lifting plate, and a plate is sleeved on the top of the limiting frame.

[0010] As a preferred embodiment of this utility model, two sets of guide rods are fixedly connected around the lower surface of the lifting plate, and two side guide plates are symmetrically fixedly connected to one end of the conveying frame near the lifting plate. The outer wall of the guide rod is slidably connected to the inner wall of the side guide plate.

[0011] As a preferred embodiment of this utility model, a fixed frame is fixedly connected to the outer wall of the transport bracket, a motor is fixedly connected to the top of the fixed frame, a transport threaded rod is fixedly connected to the output end of the motor, the outer wall of the transport threaded rod is threadedly connected to the top of the sliding frame, and a suction cup is fixedly connected to the bottom of the sliding plate.

[0012] As a preferred technical solution of this utility model, a guide rod 2 is fixedly connected to the top of the lifting slide frame, the outer wall of the guide rod 2 is slidably connected to the inner wall of the slide frame, a transport frame is fixedly connected to the upper surface of the workbench, and a stacking plate is provided on the top of the transport frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Compared with traditional devices, this utility model features a correction plate at the top of the conveyor frame. The operator can use a turntable to drive the rotating shaft, worm gear, worm wheel, and adjusting rod in a coordinated manner, causing the two correction plates to rotate synchronously in opposite directions. This adjusts the guide angle and precisely corrects the position of the sheet material during the conveying process, ensuring that sheets of different widths can be stably and accurately conveyed to the designated stacking position. This avoids conveying deviation and jamming problems caused by differences in sheet width. Simultaneously, a bidirectional threaded rod is installed at the connection between the lifting slide frame and the sliding plate. By rotating the bidirectional threaded rod, the two sliding plates can be pushed to slide synchronously in opposite directions along the inner wall of the lifting slide frame, thereby flexibly adjusting the spacing between the two rows of suction cups. This allows the suction cup assembly to adapt to sheets of different widths, achieving firm adsorption and fixation of sheets of different specifications.

[0014] 2. Compared with traditional devices, this utility model has a lifting plate and a limiting frame at the bottom of the conveyor frame. During the stacking process, the limiting frame lifts the board and suspends it from the conveyor roller, ensuring that the board is in a stable position before being grabbed. Then, the sliding frame slides precisely above the board along the horizontal guide rail. The lifting sliding frame drives the suction cup to fall precisely onto the surface of the board for adsorption, ensuring the stability of the board position during the handling process. Finally, it is accurately placed on the stacking board. This operation avoids problems such as board misalignment and stacking skew that may occur during manual stacking, ensuring the neatness and stability of the stacking and reducing the risk of board damage caused by improper stacking.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 4As shown, this utility model provides an automatic palletizing device for SMC sheets, including a workbench 1. Two symmetrically arranged conveyor frames 2 are connected to the top of the workbench 1. A support plate 4 is fixedly connected to the bottom of the conveyor frame 2. A first cylinder 6 is fixedly connected to the top of the support plate 4. A lifting plate 7 is fixedly connected to the top of the first cylinder 6. An adjusting rod 11 is symmetrically rotatably connected to the inner wall of the conveyor frame 2. A correction plate 12 is fixedly connected to the bottom of the adjusting rod 11. A transport bracket 16 is fixedly connected to the upper surface of the workbench 1. A horizontal guide rail 17 is fixedly connected to the top of the transport bracket 16. A lifting slide frame 23 is slidably connected to the bottom of the horizontal guide rail 17. A sliding frame 18 is slidably connected to the inner wall of the transport bracket 16. A second cylinder 22 is fixedly connected to the lower surface of the inner wall of the sliding frame 18. The output end of the second cylinder 22 is fixedly connected to the top of the lifting slide frame 23. A bidirectional threaded rod 24 is rotatably connected to the inner wall of the lifting slide frame 23. Two sliding plates 25 are symmetrically threaded to the outer wall of the bidirectional threaded rod 24.

[0018] Among them, the conveyor frame 2 is rotatably connected with the conveyor roller 3, and the end of the conveyor frame 2 near the lifting plate 7 is symmetrically fixedly connected with the support bearing 10. The inner wall of the support bearing 10 is rotatably connected with the outer wall of the adjusting rod 11.

[0019] The top end of the adjusting rod 11 is fixedly connected to a correction plate 12, the bottom end of the adjusting rod 11 is fixedly connected to a worm gear 13, and the conveyor frame 2 is rotatably connected to a rotating shaft 14.

[0020] Two worm gears 15 are symmetrically fixedly connected to the outer wall of the rotating shaft 14. The worm gears 15 mesh with the worm wheel 13. One end of the rotating shaft 14 extends out of the outer wall of the conveyor frame 2. A turntable 1501 is fixedly connected to the extended end of the rotating shaft 14.

[0021] It should be noted that the support bearing 10 is used to support the rotation of the adjusting rod 11. The operator can rotate the rotating shaft 14 by rotating the turntable 1501. The rotating shaft 14 will drive the two worm gears 15 to rotate. Through the meshing of the worm gears 15, the worm wheel 13 will be driven to rotate, thereby driving the adjusting rod 11 and the correction plate 12 to rotate. By rotating the correction plate 12, the guide position can be adjusted, thereby correcting the forward conveying of plates of different sizes.

[0022] Among them, two limiting frames 8 are symmetrically fixedly connected to the top of the lifting plate 7, and a plate 9 is sleeved on the top of the limiting frame 8.

[0023] Among them, two sets of guide rods 801 are fixedly connected around each other on the lower surface of the lifting plate 7, and two side guide plates 5 are symmetrically fixedly connected to one end of the conveyor frame 2 near the lifting plate 7. The outer wall of the guide rod 801 is slidably connected to the inner wall of the side guide plate 5.

[0024] It should be noted that the inner wall of the side guide plate 5 is provided with a guide ring. The inner wall of the guide ring is slidably connected to the outer wall of the guide rod 801. Under normal conditions, the first cylinder 6 will pull back the lifting plate 7 and the limiting frame 8 through the output end. Under the pull back of the output end of the first cylinder 6, the top of the limiting frame 8 will retract between the multiple conveying rollers 3. When the plate 9 is transported to one end of the limiting frame 8 by the conveying rollers 3, the operator starts the first cylinder 6 to lift the lifting plate 7 and the limiting frame 8 so that the plate 9 is suspended in the air and waiting to be transported.

[0025] The outer wall of the transport bracket 16 is fixedly connected to a fixed frame 21, the top of the fixed frame 21 is fixedly connected to a motor 20, the output end of the motor 20 is fixedly connected to a transport threaded rod 19, the outer wall of the transport threaded rod 19 is threadedly connected to the top of the sliding frame 18, and the bottom of the sliding plate 25 is fixedly connected to a suction cup 26.

[0026] It should be noted that the fixed frame 21 is used to support the operation of the motor 20. The threaded rod 19 passes through the top of the transport bracket 16. When the fixed frame 21 rotates the threaded rod 19 through the conveying end, the threaded rod 19 pushes the top of the sliding frame 18 to slide horizontally through the threaded connection. Then the sliding frame 18 will slide horizontally along the top of the transport bracket 16, thereby controlling the sliding frame 18 to reciprocate between the conveyor frame 2 and the transport frame 28.

[0027] Among them, the top of the lifting slide frame 23 is fixedly connected to the guide rod 2301, the outer wall of the guide rod 2301 is slidably connected to the inner wall of the slide frame 18, the upper surface of the workbench 1 is fixedly connected to the transport frame 28, and the top of the transport frame 28 is provided with a stacking plate 27.

[0028] It should be noted that the handling rack 28 is used to transport the stacked boards, while the stacking board 27 is used to stack the boards.

[0029] Working principle and usage process of this utility model: The specific operation is as follows: During the palletizing operation, the operator needs to transport the sheet metal 9 using the conveyor frame 2 and the conveyor roller 3. When the sheet metal 9 is transported to one side of the limiting frame 8 by the conveyor roller 3, the operator needs to activate the first cylinder 6. The first cylinder 6 pushes the lifting plate 7 and the limiting frame 8 through its output end. Under the push of the first cylinder 6, the lifting plate 7 and the limiting frame 8 rise along the guide rod 801 towards the sheet metal 9. The limiting frame 8 lifts the sheet metal 9 and suspends it from the transport of the conveyor roller 3. At this time, the operator needs to activate the motor 20. The motor 20 drives the sliding frame 18 to slide horizontally along the top of the horizontal guide rail 17 towards the position of the sheet metal 9 through its output end. When the sliding frame 18 drives the lifting sliding frame 23 and the sliding plate 25 to slide onto the sheet metal... After the material 9 is placed above the top, the operator needs to further control the second cylinder 22. The second cylinder 22 will push the lifting slide frame 23 through the output end. The lifting slide frame 23, under the force, will drive the sliding plate 25 and the suction cup 26 to slide down along the guide rod 2301 towards the top of the material 9. When the suction cup 26 contacts the surface of the material 9, it will hold the material 9 in place. At this time, the material 9 is fixed below the sliding plate 25 by the suction operation of the multiple suction cups 26. At this time, the operator needs to control the second cylinder 22 to pull back the lifting slide frame 23 and the sliding plate 25. The material 9 will move in one stroke and detach from the inner wall of the limiting frame 8. At this time, the operator needs to control the first cylinder 6 in the opposite direction to pull back the limiting frame 8 and the lifting plate 7 to their original positions. Then, the operator needs to control the motor 20 to rotate the conveying screw in the opposite direction. With the guide rod 19 in place, the sliding frame 18 will drive the fixed plate 9 to slide towards the stacking plate 27. After sliding above the stacking plate 27, the operator will activate the second cylinder 22 again to lower the lifting frame 23 and the plate 9. Then, control the suction cup 26 to release the plate 9, which will fall to the top of the stacking plate 27. Repeat the transport operation to transport and stack multiple plates 9 on top of the stacking plate 27. After stacking to a certain extent, the operator can activate the transport frame 28 to transport the stacking plate 27 and the stacked plates 9. The operator can adjust the angle of the correction plate 12 by rotating the turntable 1501 according to the width of the plate for correction and guidance. At the same time, the operator can also adjust the spacing between the two rows of suction cups 26 by rotating the bidirectional threaded rod 24. When the turntable 1501 rotates, it drives the rotating shaft 1 4. Rotation: The rotating shaft 14 further drives the two worm gears 15 to rotate. The two worm gears 15, through meshing, drive the two worm wheels 13 and the adjusting rod 11 to rotate in opposite directions inward. The two adjusting rods 11, supported by the support bearing 10, drive the correcting plate 12 to rotate synchronously. By rotating the two correcting plates 12 inward, the guide angle is adjusted, thereby correcting the conveying position according to the width of the plate 9. At the same time, in order to accommodate plates 9 of different widths, the operator needs to rotate the bidirectional threaded rod 24. The rotation of the bidirectional threaded rod 24, through the threaded connection, pushes the two sliding plates 25 to slide inward synchronously in opposite directions along the inner wall of the lifting slide frame 23, thereby reducing the distance between the two sliding plates 25 and the suction cup 26, adapting to the clamping and fixing of plates 9 of different widths.
