Description

Technical Field

[0001] This utility model relates to the field of cardboard conveying technology, and in particular to a cardboard conveying device with a correction function in carton processing. Background Technology

[0002] For example, Chinese patent CN221459289U discloses an environmentally friendly carton and paperboard production and conveying device with a correction structure. By using a correction plate to correct the deviation of the carton and paperboard, the conveying route of the carton and paperboard is restricted to the range of the correction plate. The environmentally friendly carton and paperboard production and conveying device with a correction structure can effectively improve production efficiency and product quality, and reduce paperboard damage and waste.

[0003] The existing device uses two independent motors to drive the guide plate and the correction plate respectively, which poses a risk of asynchronous motion control. When the two components deviate in action due to response delay or parameter differences, it can easily cause asymmetrical limiting of the cardboard during the conveying process, leading to deviation or even jamming, directly affecting the conveying stability. When the guide plate and the correction plate are adapted to cardboard of different specifications, excessive clamping force may occur, causing local deformation and warping of the cardboard, edge bulging, etc., which not only affects the conveying accuracy but may also cause the cardboard to wrinkle or even break. Furthermore, if the cardboard is limited and guided solely by the guide plate during the conveying process, the cardboard may collide with the guide plate, resulting in edge damage and wrinkles. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cardboard conveying device with a correction function in carton processing. It solves the technical problems in existing technologies where cardboard misalignment due to response delay or parameter differences between the two correction plates affects conveying stability, and cardboard deformation and bulging may occur due to excessive clamping when adapting to different cardboard specifications. The device achieves the goal of synchronously driving the correction plates on both sides to center and guide cardboard of different specifications and avoid cardboard deformation caused by excessive clamping, thus ensuring stable cardboard conveying.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a cardboard conveying device with a correction function in carton processing, including a conveyor belt installed in a conveyor table, a guide correction mechanism for adapting to and guiding cardboard of different specifications, and an active correction mechanism for actively traction and correction of the cardboard being conveyed.

[0006] The guiding and correcting mechanism includes a gantry frame installed on the conveyor table. A bidirectional motor is installed at the top center of the gantry frame, and bearing seats are symmetrically installed at both ends of the gantry frame. The output ends of the bidirectional motor are respectively connected to lead screws whose ends are rotatably connected to the bearing seats. A threaded slide plate is threadedly connected to the lead screw and slidably connected to the inner wall of the guide groove opened on the gantry frame. A guiding and correcting plate is installed at the bottom of the threaded slide plate. An edge-pressing component is provided at the bottom of the gantry frame to prevent the cardboard from being clamped and warped.

[0007] A further improvement is that a rubber pad and a pressure sensing strip are installed on the inner side of the guide correction plate, with the pressure sensing strip located below the rubber pad and in close contact with the surface of the conveyor belt.

[0008] A further improvement is that the pressing assembly includes an electric lifting rod installed at the bottom of the gantry frame. A connecting block is installed at the free end of the bottom of the electric lifting rod. A rotating shaft is rotatably connected in a rotating hole opened in the connecting block. Rollers are symmetrically installed at both ends of the rotating shaft. A pressure sensor is installed in the mounting groove opened at the bottom of the connecting block. Both rollers are equipped with elastic adaptive components that adapt to different specifications of paperboard.

[0009] A further improvement is that the elastic adaptive component includes a contraction hole opened at the outer end of the roller, a flexible spring installed on the inner wall of the contraction hole, a telescopic roller slidably connected to the inner wall of the contraction hole installed on the flexible spring, and the outer end of the telescopic roller abutting against the guide correction plate.

[0010] A further improvement is that a U-shaped frame is installed at the other end of the top of the conveyor platform, and T-shaped sliders are slidably connected to the inner walls of the limiting grooves symmetrically opened on both sides of the U-shaped frame, and the bottom of the T-shaped sliders is connected to the guide correction plate.

[0011] A further improvement is that the active correction mechanism includes a crossbeam installed between the gantry frame and the U-shaped frame. Multiple electric push rods are arrayed at the bottom of the crossbeam. An installation block is installed at the bottom of the electric push rod, and a pressure sensor is also installed in the installation groove at the bottom of the installation block. A rotating shaft is rotatably connected in the rotating hole opened in the installation block. Correction rollers with the same length as the rollers are symmetrically installed at both ends of the rotating shaft. Spiral grooves are symmetrically opened on the two correction rollers.

[0012] By employing the above technical solution, this utility model provides a cardboard conveying device with a correction function in cardboard box processing, which has at least the following beneficial effects: 1. This utility model uses a bidirectional motor to drive two lead screws to rotate, causing the threaded slide plate to slide relative to each other along the guide groove, thereby causing the guide correction plate to fit against the edge of the cardboard. At this time, the pressure sensing strip contacts the edge of the cardboard to generate a pressure electrical signal, and the bidirectional motor stops running, thus avoiding the cardboard from being over-clamped by the guide correction plate and deforming it. In conjunction with the rubber pad, the impact force generated by the cardboard hitting the guide correction plate during the conveying process is buffered, thereby avoiding damage to the edge of the cardboard, thus completing the centering and limiting of the cardboard and guiding and correcting it.

[0013] 2. This utility model uses an electric lifting rod to push the connecting block down until the pressure sensor at its bottom contacts the surface of the cardboard, thus covering the entire cardboard underneath and preventing the cardboard from bulging during the alignment process.

[0014] 3. This utility model uses an electric push rod to push the mounting block down until the pressure sensor at the bottom of the mounting block contacts the surface of the cardboard. At this time, the friction of the cardboard drives the two correction rollers to rotate. At the same time, the spiral grooves on the correction rollers generate a lateral thrust on the cardboard, thereby forcing the cardboard to move towards the mounting block, so that the center line of the cardboard always stays on the initial alignment axis, thereby guiding and constraining the cardboard, actively performing correction work, and preventing the cardboard from deviating to both sides.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Example 1 In existing technologies, the two alignment plates can shift the cardboard due to response delays or parameter differences, affecting conveying stability. Furthermore, when adapting to different cardboard specifications, excessive clamping may cause cardboard deformation or bulging. This embodiment provides a cardboard conveying device with alignment function for carton processing. Please refer to... Figures 1-5 This embodiment provides a cardboard conveying device with a correction function for carton processing. It can synchronously drive correction plates on both sides to center and guide cardboard of different specifications, preventing excessive clamping that could deform the cardboard and affect stable conveying. This cardboard conveying device with a correction function includes a conveyor belt 2 installed within a conveyor table 1. The conveyor table 1 is equipped with a guide correction mechanism 3 that adapts to and limits the correction of cardboard of different specifications. The guide correction mechanism 3 is equipped with an active correction mechanism 4 that actively pulls and corrects the cardboard during conveying.

[0020] The guiding and correcting mechanism 3 includes a gantry frame 31 installed on the conveyor table 1. A bidirectional motor 32 is installed at the top center of the gantry frame 31. Bearing seats 33 are symmetrically installed at both ends of the gantry frame 31. The output ends of the bidirectional motor 32 are respectively connected to lead screws 34 whose ends are rotatably connected in the bearing seats 33. A threaded slide plate 35 is threadedly connected to the lead screw 34 and slidably connected to the inner wall of the guide groove opened on the gantry frame 31. A guiding and correcting plate 36 is installed at the bottom of the threaded slide plate 35. A pressing edge assembly 39 is provided at the bottom of the gantry frame 31 to prevent the cardboard from being clamped and warped.

[0021] The inner side of the guide correction plate 36 is equipped with a rubber pad 37 and a pressure sensing strip 38. The pressure sensing strip 38 is located below the rubber pad 37 and is in close contact with the surface of the conveyor belt 2. When facing cardboard of different specifications, the bidirectional motor 32 is started to drive the two lead screws 34 to rotate in the bearing seat 33, thereby driving the threaded slide plate 35 to slide relative to each other along the guide groove, thereby driving the guide correction plate 36 at its bottom to fit against the edge of the cardboard of different specifications. When the pressure sensing strip 38 on the guide correction plate 36 contacts the edge of the cardboard, a pressure electrical signal is generated. At this time, the bidirectional motor 32 stops running, thereby avoiding the cardboard deformation caused by the excessive clamping of the guide correction plate 36. In conjunction with the rubber pad 37, the impact force generated by the cardboard hitting the guide correction plate 36 during the conveying process is buffered, thereby avoiding damage to the edge of the cardboard, thus completing the centering limit and guiding correction of the cardboard.

[0022] To prevent the cardboard from bulging due to pressure from the two guide and correction plates 36, the device is also equipped with a pressing assembly 39. The pressing assembly 39 includes an electric lifting rod 391 installed at the bottom of the gantry frame 31. A connecting block 392 is installed at the free end of the bottom of the electric lifting rod 391. A rotating shaft 393 is rotatably connected in a rotating hole opened in the connecting block 392. Rollers 394 are symmetrically installed at both ends of the rotating shaft 393. A pressure sensor 395 is installed in the mounting groove opened at the bottom of the connecting block 392. Both rollers 394 are equipped with elastic adaptive components 396 that adapt to different cardboard specifications. Before centering, the electric lifting rod 391 is activated to push the connecting block 392 down until the pressure sensor 395 at its bottom contacts the surface of the cardboard, covering it completely, thereby preventing the cardboard from bulging during the centering process.

[0023] Example 2 Since different specifications of cardboard have different diameters, in order to improve the applicability of the edge-pressing assembly 39, based on Embodiment 1, as follows: Figures 1-5 As shown, the device is also equipped with an elastic adaptive component 396. The elastic adaptive component 396 includes a shrinkage hole 3961 opened at the outer end of the roller 394. A flexible spring 3962 is installed on the inner wall of the shrinkage hole 3961. A telescopic roller 3963 is slidably connected to the inner wall of the shrinkage hole 3961 on the flexible spring 3962. The outer end of the telescopic roller 3963 abuts against the guide correction plate 36. When the guide correction plate 36 moves relative to the cardboard to center and limit it, the guide correction plate 36 simultaneously squeezes the telescopic roller 3963, causing it to press the flexible spring 3962 and slide into the shrinkage hole 3961. This ensures that the outer end of the telescopic roller 3963 is always in contact with the edge of the cardboard, and works with the roller 394 to press the cardboard as a whole, thereby preventing the cardboard from deforming and bulging.

[0024] To prevent the outer end of the guide correction plate 36 from becoming skewed after prolonged use, thus affecting the guidance and correction of the cardboard, a U-shaped frame 397 is installed at the other end of the top of the conveyor table 1 in this device. T-shaped sliders 398 are slidably connected to the inner walls of the limiting grooves symmetrically opened on both sides of the U-shaped frame 397. The bottom of the T-shaped sliders 398 is connected to the guide correction plate 36. As the guide correction plate 36 is pulled and slid by the threaded slide plate 35, the T-shaped sliders 398 are simultaneously driven to slide along the limiting grooves opened on the U-shaped frame 397. Thus, the T-shaped sliders 398 provide a support point at the end of the guide correction plate 36, preventing the end of the guide correction plate 36 from becoming skewed.

[0025] Example 3 To reduce the impact of cardboard on the guide and correction plate 36 during transport, which could cause edge damage, therefore, based on Embodiment 2, as follows: Figures 1-5 As shown, the device is also equipped with an active correction mechanism 4. The active correction mechanism 4 includes a crossbeam 41 installed between the gantry frame 31 and the U-shaped frame 397. Multiple electric push rods 42 are arrayed at the bottom of the crossbeam 41. A mounting block 43 is installed at the bottom of the electric push rod 42, and a pressure sensor 395 is also installed in the mounting groove opened at the bottom of the mounting block 43. A rotating shaft 44 is rotatably connected in the rotating hole opened in the mounting block 43. Correction rollers 45 with the same length as the rollers 394 are symmetrically installed at both ends of the rotating shaft 44. The two correction rollers 45 are symmetrically opened. With spiral grooves 46, during the paperboard conveying process, the electric push rod 42 is activated to push the mounting block 43 down until the pressure sensor 395 at the bottom of the mounting block 43 contacts the paperboard surface. At this time, the friction of the paperboard drives the two correction rollers 45 to rotate. At the same time, the spiral grooves 46 on the correction rollers 45 generate a lateral thrust on the paperboard, thereby forcing the paperboard to move towards the mounting block 43, so that the center line of the paperboard always stays on the initial alignment axis, thereby guiding and constraining the paperboard, actively performing correction work, and preventing the paperboard from deviating to both sides.
