Description

Technical Field

[0001] This application relates to the field of cardboard box processing equipment technology, and in particular to an automatic feeding device for a cardboard box shearing machine. Background Technology

[0002] A shearing machine is a device for cutting cardboard. It is used to cut cardboard into corresponding shapes to facilitate the subsequent production of cartons.

[0003] Currently, the common conveying device of shearing machines is usually a conveyor belt, which achieves the conveying function through the friction between the cardboard and the conveyor belt during use.

[0004] However, in actual production, some parts of the cardboard are covered with smooth advertising paper. Since most of the advertising paper is covered with a plastic film, this causes local deviations in the friction between different parts of the cardboard and the conveyor belt. As a result, the cardboard will tilt during the conveying process. Since shearing machines usually cut the cardboard at a fixed angle and direction, the effect of the cardboard after shearing will not meet the design requirements and there will be obvious shortcomings. Utility Model Content

[0005] In order to improve the problem that cardboard is prone to skewing during the conveying process, this application provides an automatic feeding device for a carton shearing machine.

[0006] The automatic feeding device for a cardboard box shearing machine provided in this application adopts the following technical solution:

[0007] An automatic feeding device for a cardboard shearing machine includes a shearing machine and a robotic arm. The feeding end of the shearing machine is provided with a feeding platform. The robotic arm is used to place cardboard on the feeding platform. The feeding platform is provided with a straightening component for changing the placement posture of the cardboard. A pusher plate is slidably arranged on the feeding platform for pushing the cardboard toward the feeding end of the shearing machine. The feeding platform is provided with a driving assembly for driving the pusher plate to slide.

[0008] By adopting the above technical solution, the robot first places the cardboard on the feeding platform, then the straightening component changes and adjusts the position and posture of the cardboard on the feeding platform, and then the drive component drives the pusher plate to slide. The sliding pusher plate pushes the cardboard to the shearing machine for cutting, thereby reducing the possibility of the cardboard shifting during the conveying process and improving the qualification of the cardboard cutting effect.

[0009] Optionally, the corrective component includes a clamping cylinder disposed on the feeding platform. The clamping cylinder is located on both sides of the paperboard conveying direction. The clamping cylinder is electrically connected to the control system. A clamping plate is disposed on the piston rod of the clamping cylinder. The clamping plate is used to abut against the side of the paperboard.

[0010] By adopting the above technical solution, after the cardboard is placed on the feeding platform, the control system activates the clamping cylinders on both sides of the cardboard conveying direction. The piston rod of the clamping cylinder pushes the clamping plate closer to the side of the cardboard, thereby achieving the effect of adjusting the position and posture of the cardboard, which facilitates the subsequent pusher plate to push the cardboard.

[0011] Optionally, the drive assembly includes a conveyor shaft rotatably mounted on the feeding platform and located at both ends of the cardboard conveying direction. Multiple sprockets are arranged on the conveyor shaft along its axial direction. A chain is wound between each pair of corresponding sprockets on the two conveyor shafts. The pusher plate is disposed on a link of the chain. A drive component for driving the conveyor shaft to rotate is provided on the feeding platform.

[0012] By adopting the above technical solution, the driving component drives the conveyor shaft to rotate, the rotating conveyor shaft drives the pusher plate to slide, and the sliding pusher plate pushes the cardboard towards the shearing machine, thereby achieving the effect of automatically pushing the cardboard closer to the shearing machine.

[0013] Optionally, the driving component includes a reduction gearbox mounted on the feeding platform, with the end of the conveying shaft near one end of the shearing machine connected to the output end of the reduction gearbox, and a drive motor electrically connected to the control system mounted on the reduction gearbox, the output shaft of the drive motor connected to the input end of the reduction gearbox.

[0014] By adopting the above technical solution, the control system starts the drive motor, and the output shaft of the drive motor transmits the torque to the conveyor shaft through the reduction gearbox. The conveyor shaft drives the chain to rotate through the sprocket, thereby achieving the effect of conveying the cardboard.

[0015] Optionally, the feeding platform has two tensioning columns at the end facing away from the shearing machine. The axis of the tensioning columns is parallel to the direction from the feeding platform to the shearing machine. Both ends of the conveying shaft away from the shearing machine are rotatably equipped with bearing seats. Each bearing seat corresponds to one of the tensioning columns and is slidably engaged with the tensioning columns. The feeding platform has two tensioning cylinders electrically connected to the control system. Each tensioning cylinder corresponds to one of the bearing seats, and the bearing seats are mounted on the piston rods of the tensioning cylinders.

[0016] By adopting the above technical solution, when the chain becomes loose after working for a long time, the worker starts the tensioning cylinder through the control system. The piston rod of the tensioning cylinder pushes the shaft seat to slide, and the shaft seat drives the conveyor shaft connected to it to slide synchronously, thereby increasing the wheel distance between the two conveyor shafts, which in turn tightens the chain, thereby improving the accuracy of distance control when the paperboard is cut when the pusher plate pushes the paperboard to slide.

[0017] Optionally, the surface of the feeding platform is provided with a plurality of clearance grooves, each clearance groove corresponding to a chain, and the chain is located within the clearance groove.

[0018] By adopting the above technical solution, the possibility of direct contact between the cardboard and the chain is reduced, and the possibility of the cardboard surface being contaminated by oil stains on the chain is also reduced.

[0019] Optionally, multiple pusher plates are evenly arranged on the chain. Each pusher plate includes a bottom support and an inclined pusher plate. The bottom support is disposed on a link of the chain, and the inclined pusher plate is rotatably disposed on the bottom support. A torsion spring is disposed between the bottom support and the inclined pusher plate. In the direction in which the cardboard slides toward the shearing machine, a stop block is disposed on the side of the inclined pusher plate facing away from the shearing machine, and the torsion spring presses the inclined pusher plate tightly against the stop block.

[0020] By adopting the above technical solution, when the robot places the cardboard on the inclined push plate, the inclined push plate will rotate around its rotation center. At this time, the torsion spring will deform until the cardboard is attached to the upper surface of the feeding platform. At this time, the inclined push plate located below the cardboard will be stored in the clearance groove. As the chain rotates, the nearest inclined push plate on the side of the cardboard facing away from the shearing machine will gradually abut against the cardboard, thereby causing the cardboard to slide towards the shearing machine.

[0021] Optionally, the inclined push plate is arranged obliquely towards the stop block in a downward direction, and a pressing arc surface is provided at the end of the inclined push plate facing away from the stop block. When the cardboard is pressed on the pressing arc surface, the inclined push plate rotates into the clearance groove, and the pressing arc surface slides in cooperation with the lower surface of the cardboard.

[0022] By adopting the above technical solution, the inclined push plate located below the cardboard, under the action of the torsion spring, makes the pressing arc surface of the inclined push plate abut against the lower surface of the cardboard. As the chain rotates, the pressing arc surface of the inclined push plate will slide relative to the lower surface of the cardboard, thereby reducing the possibility of the inclined push plate causing damage to the lower surface of the cardboard.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The robot first places the cardboard on the feeding platform, then the straightening component changes and adjusts the position and posture of the cardboard on the feeding platform, and then the drive component drives the pusher plate to slide. The sliding pusher plate pushes the cardboard to the shearing machine for cutting, thereby reducing the possibility of cardboard deviation during the conveying process and improving the qualification of cardboard cutting effect.

[0025] 2. When the chain becomes loose after working for a long time, the worker starts the tensioning cylinder through the control system. The piston rod of the tensioning cylinder pushes the shaft seat to slide, and the shaft seat drives the conveyor shaft connected to it to slide synchronously, thereby increasing the wheel distance between the two conveyor shafts, which in turn tightens the chain, thereby improving the accuracy of distance control when the paperboard is cut when the pusher plate pushes the paperboard to slide.

[0026] 3. When the robot places the cardboard on the inclined push plate, the inclined push plate will rotate around its rotation center. At this time, the torsion spring will deform until the cardboard is in contact with the upper surface of the feeding platform. At this time, the inclined push plate located below the cardboard will be stored in the clearance groove. As the chain rotates, the nearest inclined push plate on the side of the cardboard facing away from the shearing machine will gradually abut against the cardboard, thereby causing the cardboard to slide towards the shearing machine.

[0031] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0032] This application discloses an automatic feeding device for a cardboard box shearing machine.

[0033] Reference Figure 1An automatic feeding device for a cardboard shearing machine includes a shearing machine 2 and a robot arm 3. The robot arm 3 is electrically connected to the control system. A feeding platform 4 is arranged between the feeding end of the shearing machine 2 and the robot arm 3. The robot arm 3 is used to place cardboard 1 on the feeding platform 4. A corrective element 5 for changing the placement posture of the cardboard 1 is arranged on the feeding platform 4.

[0034] Reference Figure 1 The straightening component 5 includes a clamping cylinder 51 that is bolted to the feeding platform 4 and electrically connected to the control system. The clamping cylinder 51 is located on both sides of the paperboard 1 in the conveying direction. A clamping plate 52 is bolted to the piston rod of the clamping cylinder 51. The clamping plate 52 is used to abut against the side of the paperboard 1 in the conveying direction.

[0035] The control system starts the robotic arm 3, which places the cardboard 1 on the loading platform 4. Then the control system starts the clamping cylinder 51, and the piston rod of the clamping cylinder 51 pushes the clamping plate 52 close to the side of the cardboard 1, thereby straightening the cardboard 1.

[0036] Reference Figure 1 A pusher plate 6 is slidably arranged on the feeding platform 4. The pusher plate 6 is used to push the cardboard 1 toward the feeding end of the shearing machine 2. A drive assembly 7 for driving the pusher plate 6 to slide is arranged on the feeding platform 4.

[0037] Reference Figure 1 and Figure 2 The drive assembly 7 includes a conveyor shaft 71 rotatably connected to the feeding platform 4 and located at both ends of the cardboard 1 conveying direction. Four sprockets 72 are bolted to the conveyor shaft 71 along its axial direction, and a chain 73 is wound between each pair of corresponding sprockets 72 on the two conveyor shafts 71.

[0038] Reference Figure 1 , Figure 2 and Figure 3 The upper surface of the feeding platform 4 is provided with four clearance grooves 11, which correspond one-to-one with the chain 73. The chain 73 is located in the clearance groove 11. The pusher plate 6 is arranged on the chain link of the chain 73. Multiple pusher plates 6 are evenly arranged circumferentially on the chain 73.

[0039] Reference Figure 2 and Figure 3 The pusher plate 6 includes a bottom base 61 and an inclined pusher plate 62. The bottom base 61 has a U-shaped cross-section and is welded to the chain link of the chain 73. The inclined pusher plate 62 can be made of lightweight plastic material. The inclined pusher plate 62 is rotatably connected to the bottom base 61. A torsion spring 63 is arranged between the bottom base 61 and the inclined pusher plate 62. In the direction in which the cardboard 1 slides toward the shearing machine 2, an L-shaped stop block 64 is welded to the side of the inclined pusher plate 62 facing away from the shearing machine 2.

[0040] Reference Figure 2 and Figure 3 The torsion spring 63 presses the inclined push plate 62 against the stop block 64. The inclined push plate 62 is inclined towards the stop block 64 in a downward direction. The end of the inclined push plate 62 facing away from the stop block 64 is provided with a pressing arc surface 12. When the cardboard 1 is pressed against the pressing arc surface 12, the inclined push plate 62 below the cardboard 1 will rotate into the relief groove 11, and the pressing arc surface 12 will slide and engage with the lower surface of the cardboard 1.

[0041] Reference Figure 1 The loading platform 4 is equipped with a drive unit 74 that drives the conveyor shaft 71 to rotate. The drive unit 74 includes a reduction gearbox 741 bolted to the loading platform 4. The end of the conveyor shaft 71 near the shearing machine 2 is connected to the output end of the reduction gearbox 741. A drive motor 742 electrically connected to the control system is bolted to the reduction gearbox 741. The output shaft of the drive motor 742 is connected to the input end of the reduction gearbox 741.

[0042] When the placed cardboard 1 is pressed against the pressing arc surface 12 on the inclined push plate 62, the inclined push plate 62 rotates under the gravity of the cardboard 1 until the cardboard 1 is attached to the upper surface of the feeding platform 4. During this process, the torsion spring 63 deforms and the inclined push plate 62 rotates into the clearance groove 11. At the same time, the pressing arc surface 12 on the inclined push plate 62 abuts against the lower surface of the cardboard 1, and then the control system starts the drive motor 742.

[0043] The output shaft of the drive motor 742 drives the conveyor shaft 71 to rotate through the reduction gearbox 741. The conveyor shaft 71 drives the chain 73 to rotate through the sprocket 72. At this time, the pressing arc surface 12 of the inclined push plate 62 located on the lower surface of the cardboard 1 will slide relative to the lower surface of the cardboard 1 until the inclined push plate 62 closest to the robot arm 3 abuts the end of the cardboard 1. At this time, as the chain 73 continues to rotate, the cardboard 1 is conveyed to the shearing machine 2 for cutting.

[0044] Reference Figure 1 Two tensioning columns 8 are welded to the end of the feeding platform 4 facing away from the shearing machine 2. The axis of the tensioning column 8 is parallel to the direction from the feeding platform 4 to the shearing machine 2. Both ends of the conveying shaft 71 away from the shearing machine 2 are rotatably connected to the bearing seat 9.

[0045] Reference Figure 1 The bearing seat 9 corresponds to the tensioning column 8 one by one, and the bearing seat 9 and the tensioning column 8 slide together. Two tensioning cylinders 10, which are electrically connected to the control system, are bolted on the feeding platform 4. The tensioning cylinders 10 correspond to the bearing seat 9 one by one, and the bearing seat 9 is bolted to the piston rod of the tensioning cylinder 10.

[0046] Before conveying the cardboard 1, the worker first activates the tension cylinder 10 through the control system. The piston rod of the tension cylinder 10 pushes the shaft seat 9 to slide, and the shaft seat 9 drives the conveyor shaft 71 connected to it to slide synchronously, thereby increasing the wheelbase between the two conveyor shafts 71 and adjusting the tension of the chain 73.

[0047] The implementation principle of the automatic feeding device for a carton shearing machine in this application embodiment is as follows: Before conveying the cardboard 1, the worker first starts the tension cylinder 10 through the control system. The piston rod of the tension cylinder 10 pushes the shaft seat 9 to slide, and the shaft seat 9 drives the conveying shaft 71 connected to it to slide synchronously, thereby increasing the axial distance between the two conveying shafts 71, and thus adjusting the tension of the chain 73.

[0048] The control system starts the robotic arm 3, which places the cardboard 1 on the loading platform 4. Then the control system starts the clamping cylinder 51, and the piston rod of the clamping cylinder 51 pushes the clamping plate 52 close to the side of the cardboard 1, thereby straightening the cardboard 1.

[0049] When the placed cardboard 1 is pressed against the pressing arc surface 12 on the inclined push plate 62, the inclined push plate 62 rotates under the gravity of the cardboard 1 until the cardboard 1 is attached to the upper surface of the feeding platform 4. During this process, the torsion spring 63 deforms and the inclined push plate 62 rotates into the clearance groove 11. At the same time, the pressing arc surface 12 on the inclined push plate 62 abuts against the lower surface of the cardboard 1, and then the control system starts the drive motor 742.

[0050] The output shaft of the drive motor 742 drives the conveyor shaft 71 to rotate through the reduction gearbox 741. The conveyor shaft 71 drives the chain 73 to rotate through the sprocket 72. At this time, the pressing arc surface 12 of the inclined push plate 62 located on the lower surface of the cardboard 1 will slide relative to the lower surface of the cardboard 1 until the inclined push plate 62 closest to the robot arm 3 abuts the end of the cardboard 1. At this time, as the chain 73 continues to rotate, the cardboard 1 is conveyed to the shearing machine 2 for cutting.

[0051] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
