Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard production and processing technology, specifically to a receiving device for corrugated cardboard. Background Technology

[0002] Corrugated cardboard is a lightweight board material made of multiple layers of paper, named for its unique corrugated core structure, and is one of the core materials of the modern packaging industry. As the most widely used packaging material globally, corrugated cardboard plays an irreplaceable role in e-commerce express delivery, food transportation, and industrial equipment protection. With the development of the circular economy, more than 85% of corrugated cardboard can be recycled, significantly reducing its carbon footprint and becoming an important carrier of the green supply chain.

[0003] Chinese patent CN205328283U discloses an automatic honeycomb paperboard collecting device. Its suction mechanism, after sensing the honeycomb paperboard, uses a PLC control system to control a vacuum suction disc to move downwards and suck up the paperboard. Then, according to a set target, it moves the paperboard laterally to the top of a material cart to release it, thus realizing the paperboard collecting operation after cutting. However, the device in the aforementioned patent still has some shortcomings in actual use. The paperboard cutting speed is relatively fast, while the suction mechanism's collecting speed is slow, making it difficult to meet the material feeding requirements. Furthermore, the paperboard is easily wrinkled and damaged when sucked up by the suction mechanism during transport; otherwise, the conveyor belt needs to be stopped before suction can be performed, which further affects the collecting efficiency. Further development and improvement are needed. Utility Model Content

[0004] The purpose of this invention is to provide a cardboard collecting device to solve the problems of slow cardboard collecting efficiency and easy wrinkling and damage during the collecting process.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: A receiving device for corrugated cardboard includes a workbench, a conveyor belt conveying mechanism is arranged in the middle of the workbench, a sliding support beam is arranged longitudinally above the workbench, and support columns are arranged between the top of the workbench and the sliding support beam on both sides of the longitudinal direction of the conveyor belt conveying mechanism. Two movable support plates are slidably connected to the top of the sliding support beam longitudinally. A linear transmission mechanism is arranged on one side of the movable support plate in the transverse direction of the sliding support beam, and a lifting device is arranged on the top of the other side. A lifting support plate is installed at the bottom output end of the lifting device through the movable support plate. A suction plate is slidably connected to the bottom of the lifting support plate in the transverse direction. A vacuum pump is arranged at the top of the lifting support plate. Several suction cups are arranged in an array at the bottom of the suction plate, and the suction cups are all connected to the output end of the vacuum pump. A limit plate is arranged on the upper part of the suction plate on the side of the lifting support plate away from the feeding end of the conveyor belt conveying mechanism in the transverse direction. A fixed mounting plate is arranged on the top of the lifting support plate, and a spring is arranged between the fixed mounting plate and the limit plate.

[0006] Furthermore, material bins are provided on both longitudinal sides of the workbench corresponding to the position of the suction plate.

[0007] Furthermore, the sliding support beam and the support column, as well as the support column and the worktable, are fixedly connected by welding.

[0008] Furthermore, the linear transmission mechanism is a transmission structure in which a drive motor is equipped with a transmission gear that meshes with a transmission rack.

[0009] Furthermore, the lifting support plate is provided with a guide plug rod on the lateral side of the lifting device, and the guide plug rod is plugged into the movable support plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the utility model has a reasonable design, simple and stable structure, and strong practicality; it uses a double suction mechanism to absorb and collect the corrugated cardboard being transported, thereby improving the collection efficiency and solving the problem that the traditional suction mechanism has a slow collection speed while the corrugated cardboard cutting speed is relatively fast; at the same time, the lifting device drives the lifting support plate to descend, so that during the process of the suction plate absorbing the corrugated cardboard, the suction plate can slide along the direction of the conveyor belt conveyor mechanism, avoiding the situation of wrinkles and damage caused by direct suction of the corrugated cardboard during the transmission process. After the corrugated cardboard is sucked up, under the action of the spring, the fixed mounting plate and the limiting plate, the suction plate is quickly reset, so as to accurately send the sucked corrugated cardboard into the material box.

[0017] Combination Figures 1 to 3The illustrated material receiving device for corrugated cardboard includes a workbench 1, a conveyor belt conveying mechanism 2 in the middle of the workbench 1, a sliding support beam 3 arranged longitudinally above the workbench 1, and support columns 4 arranged between the top of the workbench 1 and the sliding support beam 3 on both sides of the longitudinal direction of the conveyor belt conveying mechanism 2. Two movable support plates 5 are slidably connected to the top of the sliding support beam 3 longitudinally. A linear transmission mechanism 6 is arranged on one side of the movable support plate 5 in the transverse direction of the sliding support beam 3, and a lifting device 7 is arranged on the top of the other side. A lifting support plate 8 is installed at the bottom output end of the lifting device 7 through the movable support plate 5. A suction plate 9 is slidably connected to the bottom of the lifting support plate 8 in the transverse direction. A vacuum pump 10 is arranged on the top of the lifting support plate 8. Several suction cups 11 are arranged in an array at the bottom of the suction plate 9, and all suction cups 11 are connected to the output end of the vacuum pump 10. A limit plate 12 is arranged on the upper part of the suction plate 9 on the side of the lifting support plate 8 away from the feeding end of the conveyor belt conveying mechanism 2. A fixed mounting plate 13 is arranged on the top of the lifting support plate 8, and a spring 14 is arranged between the fixed mounting plate 13 and the limit plate 12.

[0018] Material boxes 15 are provided on both longitudinal sides of the workbench 1 corresponding to the suction plate 9, to accommodate the dual suction mechanism and collect and store the corrugated cardboard after cutting. The sliding support beam 3 and the support column 4, as well as the support column 4 and the workbench 1, are fixedly connected by welding to ensure the stability and robustness of the connection structure, improving safety and service life. The linear transmission mechanism 6 is a transmission structure with a drive motor and a transmission gear and rack meshing, used to drive the moving support plate 5 to reciprocate laterally. A guide rod 16 is provided on the lateral side of the lifting device 7 for the lifting support plate 8. 6 is plugged into the movable support plate 5 to prevent horizontal rotation of the lifting support plate 8 during the lifting process; a photoelectric sensor is installed at the bottom of the sliding support beam 3 to monitor the corrugated cardboard transmitted on the conveyor belt conveying mechanism 2; a control device is also installed on one side of the workbench 1. The rotary motor in the conveyor belt conveying mechanism 2, the drive motor in the linear transmission mechanism 6, the lifting device 7, the vacuum pump 10, and the photoelectric sensor are all electrically connected to the control device to receive the signals transmitted by the photoelectric sensor and to control the working status of the rotary motor in the conveyor belt conveying mechanism 2, the drive motor in the linear transmission mechanism 6, the lifting device 7, and the vacuum pump 10.

[0019] During operation, the conveyor belt mechanism 2 continuously transports the cut corrugated cardboard to the discharge end. When the corrugated cardboard moves directly below the suction plate 9, the photoelectric sensor at the bottom of the sliding support beam 3 detects a signal and sends it back to the control device. The control device simultaneously activates two suction mechanisms: the lifting device 7 drives the lifting support plate 8 to descend, causing the suction cups 11 on the suction plate 9 to contact the surface of the corrugated cardboard; after the vacuum pump 10 is started, the suction cups 11 adsorb the cardboard, while the conveyor belt mechanism 2 remains operational. At the moment of adsorption, the suction plate 9 slides laterally along the lifting support plate 8 due to the inertia of the cardboard, the spring 14 is compressed, and the suction plate 9 moves synchronously with the cardboard, avoiding hard pulling that could cause wrinkles. After adsorption is complete, the lifting device 7 drives the suction plate 9 to rise, and the spring 14 pushes the limit plate 12 to reset the suction plate 9 to its initial position. At the same time, the linear transmission mechanism 6 drives the moving support plate 5 to move laterally along the sliding support beam 3, precisely transferring the adsorbed cardboard directly above the material box 15. After the vacuum pump 10 is turned off, the cardboard falls into the material bin 15 to complete the material collection. The two sets of suction mechanisms alternately adsorb and transfer, achieving a rhythm matching with the high-speed cutting process and greatly improving the material collection efficiency.
