Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, specifically to a cardboard packing and sorting device. Background Technology

[0002] Waste cardboard boxes are a significant source of recyclable materials generated in production, daily life, and logistics warehousing. To facilitate the stacking, transportation, and recycling of waste cardboard boxes, it is necessary to centrally pack and organize them. However, traditional cardboard box packing and sorting equipment still has shortcomings in its use. For example, a waste paper compaction and baling device with publication number CN212448229U uses a threading groove 1 on the base plate and a threading groove 2 on the pressure plate to allow the binding rope to be placed on the upper and lower surfaces of the compacted waste paper, thus facilitating convenient and quick bundling of the compacted waste paper. However, in use, this device still relies entirely on manual labor for the initial operations such as threading, guiding, and wrapping the rope, resulting in low automation, high labor intensity, and low overall baling production efficiency. In addition, some traditional cardboard packing and sorting devices have limited functions, with only a compaction structure. After the cardboard is compacted and bundled, it is mostly necessary to manually open the protective door and manually drag and move the materials for unloading. The overall unloading process is cumbersome and laborious. At the same time, the compacted cardboard is stacked tightly and has a large weight. Manually moving and removing it is not only inconvenient and time-consuming, but also poses certain safety hazards, further reducing the overall work efficiency. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a cardboard packing and sorting device, comprising: The frame has a side plate 1 and a side plate 2 fixedly installed on both sides. The surface of the side plate 2 has a rope passage hole, which is used to provide a passage for the rope to be tied and to prevent the rope from shifting. A top plate is fixedly installed on the top of the frame, and a back plate is fixedly installed on the outer surface of the frame. The back plate is used to block the cardboard material and provide support for the material during feeding and compaction. The material placement mechanism is installed on the side of the frame away from the back panel. The material placement mechanism is located at the feeding end of the frame and is used to carry the waste cardboard boxes to be packaged, while realizing the automatic unloading of the finished products after packaging. The compaction mechanism is installed on the top plate. The compaction mechanism is used to apply downward pressure to the waste cardboard, compact and shape the scattered cardboard, reduce the volume of the material, and facilitate subsequent bundling and storage. The binding mechanism consists of a rope-releasing component and a rope-retracting component. Both the rope-releasing component and the rope-retracting component are installed on the outer surface of the second side plate. The rope-releasing component is used to store and release the binding rope to achieve a continuous supply of the binding rope. The rope-retracting component is used to pull and tighten the binding rope. Together with the compaction process, the automatic binding of the carton board is completed, reducing manual rope threading and rope retraction operations. The material placement mechanism includes a rotatable L-shaped material placement plate and a drive box. The L-shaped material placement plate is used to support and stack waste cardboard boxes and to unload finished products by rotation. The material placement side of the L-shaped material placement plate is provided with rope placement grooves. The rope placement grooves are evenly distributed on the inner curved surface of the L-shaped material placement plate. The rope placement grooves are used to accommodate and arrange the binding ropes, so that the binding ropes are pre-laid on the bottom of the cardboard boxes. The rope clamping strips are fixedly installed inside the rope placement grooves. The rope clamping strips are set at both ends of the rope placement grooves and are used to clamp and limit the binding ropes in the rope placement grooves. The compaction mechanism includes a hydraulic cylinder, which is fixedly installed on the top of the top plate. A telescopic rod is fixedly connected to the telescopic end of the hydraulic cylinder. The telescopic rod passes through the top plate and extends to its bottom. A pressure plate is fixedly installed at the bottom end of the telescopic rod. The hydraulic cylinder drives the telescopic rod to extend and retract, causing the pressure plate to move vertically up and down. The pressure plate is used to directly squeeze the cardboard board to achieve material compaction and shaping. A rope groove is opened at the bottom of the pressure plate to accommodate the binding ropes above the cardboard board, preventing the ropes from being squeezed and damaged during the compaction process. The rope groove is located directly above the rope groove to ensure precise alignment of the upper and lower ropes and complete wrapping of the cardboard board. A limiting component is installed inside the rope groove to elastically limit the ropes in the rope groove, preventing the ropes from coming out of the rope groove. At the same time, it can automatically open during unloading to facilitate the ropes to detach.

[0004] Preferably, a rotating rod is fixedly installed at the bend of the L-shaped material placement plate. The rotating rod is rotatably installed inside the frame and is used to drive the L-shaped material placement plate to rotate. Gears are fixedly installed at both ends of the rotating rod, and the drive box is fixedly installed on both sides of the outer surface of the frame. The drive box houses a motor 1 fixedly mounted inside via a bracket. A gear 2 is fixedly connected to the output end of the motor 1, and the gear 2 meshes with the gear 1. The drive box is used to enclose and protect the internal drive components, preventing dust and debris from entering and affecting the transmission. The gear 2 transmits the power of the motor 1 to the gear 1, achieving stable power transmission and ensuring smooth rotation of the L-shaped material plate.

[0005] Preferably, guide posts are fixedly installed at the four corners of the top of the pressure plate. The guide posts are slidably installed on the surface of the top plate. The guide posts are used to guide and limit the lifting and lowering movement of the pressure plate to prevent the pressure plate from deviating during the lifting and lowering process and to ensure that the compaction operation is carried out smoothly.

[0006] Preferably, the limiting component includes a fixed rod, which is fixedly installed on both sides inside the rope groove. An arc-shaped limiting plate is rotatably installed on the outer surface of the fixed rod. The inner curved surface of the arc-shaped limiting plate directly fits the binding rope to limit and block the rope. A slot is provided at the edge of the arc-shaped limiting plate to increase the contact area with the binding rope and improve the limiting effect. A torque spring is fixedly connected between the arc-shaped limiting plate and the fixed rod. The torque spring is sleeved on the outer surface of the fixed rod and provides elastic torque to the arc-shaped limiting plate. Under normal conditions, the arc-shaped limiting plate is pushed to close to limit the rope. When compressed, the arc-shaped limiting plate elastically opens to facilitate the rope's release.

[0007] Preferably, the slots are evenly distributed on the surface of the arc-shaped limiting plate, and the slots on the two arc-shaped limiting plates are staggered and matched with each other. The staggered slots improve the reliability of the limiting.

[0008] Preferably, the rope release component includes a release frame, which is fixedly installed on the side of the frame near the second side plate. A release drum is rotatably installed inside the release frame, and a binding rope is wound around the outer surface of the release drum. The release drum can rotate freely to achieve smooth release of the binding rope.

[0009] Preferably, the unwinding frame is equipped with a rope guide frame inside, and pneumatic cutting blades are installed on both the upper and lower sides of the rope guide frame. The pneumatic cutting blades are used to cut the binding rope simultaneously after the binding is completed, so as to achieve automatic rope cutting.

[0010] Preferably, the rope winding component includes a winding frame, which is fixedly installed on the outer surface of the frame and positioned directly above the unwinding frame. A second motor is fixedly installed on the outer surface of the winding frame, and a rotating shaft is fixedly connected to the output end of the second motor. The rotating shaft is rotatably installed inside the winding frame, and a rotating drum is fixedly installed on the outer surface of the rotating shaft. An elastic pressure band is fixedly installed on the outer surface of the rotating drum. The second motor drives the rotating shaft to rotate, causing the rotating drum to rotate synchronously. The rotating drum is used to drive the elastic pressure band to rotate, thereby achieving rope traction. The elastic pressure band uses its own elasticity to compress and fix the end of the binding rope, preventing the binding rope from loosening during winding.

[0011] Preferably, the elastic pressure band is arranged parallel to the axis of the rotating drum, and the elastic pressure band is evenly distributed along the axis of the rotating drum. The elastic pressure band clamps multiple binding ropes to ensure that the cardboard is evenly bound.

[0012] Preferably, the movable end of the binding rope is squeezed and adapted to the elastic pressure band to achieve fixed clamping of the rope body and ensure smooth rope winding operation. The binding rope is sequentially passed through the rope frame, rope hole, rope placement groove and rope threading groove so that the binding rope completely wraps the cardboard box to be packed.

[0013] This invention provides a cardboard packing and sorting device. It has the following beneficial effects: (i) The cardboard packing and sorting device, through the setting of the binding mechanism, the rope feeding and rope taking parts cooperate with the rope placement groove and rope threading groove to complete the positioning and layout of the binding rope in advance. The motor drives the rotating drum and the elastic pressure belt to automatically pull and tighten the binding rope, eliminating the need for manual rope threading, rope guiding, and rope winding operations, greatly improving the automation level of the equipment and speeding up the overall cardboard packing operation efficiency.

[0014] (ii) The cardboard packing and sorting device, through the setting of the material placement mechanism, can automatically unload the L-shaped material placement plate by driving the rotating rod of the motor to rotate 90 degrees after packing. This eliminates the need for manual opening of the protective door and manual dragging and handling of the compacted cardboard, simplifying the unloading process and avoiding the inconvenience, time and labor costs of manual handling caused by the large weight of the cardboard, thus further improving the overall operating efficiency.

[0015] (III) The cardboard packing and sorting device, through the cooperation of the limiting component and the rope clamp, can clamp and limit the bottom binding rope, and the arc-shaped limiting plate in the limiting component, together with the torque spring, can elastically limit the upper binding rope, effectively preventing the binding rope from shifting or slipping during the feeding and compaction process, ensuring that the binding rope is neatly arranged, and ensuring the stability and firmness of the cardboard packing.

[0016] (iv) The cardboard packing and sorting device, with the setting of a pneumatic cutter, can automatically and synchronously cut the binding rope after the cardboard is pressed and tied in place, without the need for manual cutting of the rope, further simplifying the packing operation steps and improving the continuity of equipment operation.

[0020] Example 1, please refer to Figure 1-5 The present invention provides a technical solution: a cardboard packing and sorting device, comprising: The frame 1 has side plates 2 and 3 fixedly installed on both sides. The surface of the side plate 3 has a rope hole 9, which is used to provide a passage for the rope to be tied and to prevent the rope from shifting. The top plate 5 is fixedly installed on the top of the frame 1. The back plate 10 is fixedly installed on the outer surface of the frame 1. The back plate 10 is used to block the cardboard material and provide support for the material during feeding and compaction. The material placement mechanism 4 is installed on the side of the frame 1 away from the back plate 10. The material placement mechanism 4 is located at the feeding end of the frame 1. The material placement mechanism 4 is used to carry the waste cardboard to be packaged and to realize the automatic unloading of the finished product after packaging. The material feeding mechanism 4 includes a rotatable L-shaped feeding plate 41 and a drive box 42. The L-shaped feeding plate 41 is used to support and stack waste cardboard boxes and unload finished products by rotation. The feeding side of the L-shaped feeding plate 41 is provided with a rope groove 47. The rope grooves 47 are evenly distributed on the inner curved surface of the L-shaped feeding plate 41. The rope grooves 47 are used to accommodate and arrange the binding ropes, so that the binding ropes are pre-laid on the bottom of the cardboard box. The rope clamping strips 48 are fixedly installed inside the rope grooves 47. The rope clamping strips 48 are set at both ends of the rope grooves 47. The rope clamping strips 48 are used to clamp and limit the binding ropes in the rope grooves 47. A rotating rod 43 is fixedly installed at the bend of the L-shaped material plate 41. The rotating rod 43 is rotatably installed inside the frame 1. The rotating rod 43 is used to drive the L-shaped material plate 41 to rotate. Gears 44 are fixedly installed at both ends of the rotating rod 43. The drive box 42 is fixedly installed on both sides of the outer surface of the frame 1. The drive box 42 is equipped with a motor 45 fixedly mounted inside by a bracket. The output end of the motor 45 is fixedly connected to a gear 46. The gear 46 meshes with the gear 44. The drive box 42 is used to enclose and protect the internal drive components to prevent dust and debris from entering and affecting the transmission. The gear 46 transmits the power of the motor 45 to the gear 44, realizing stable power transmission and ensuring that the L-shaped material plate 41 rotates smoothly. The compaction mechanism 6 is installed on the top plate 5. The compaction mechanism 6 is used to apply downward pressure to the waste cardboard, compact and shape the scattered cardboard, reduce the volume of the material, and facilitate subsequent bundling and storage. The binding mechanism consists of a rope-releasing component 7 and a rope-retracting component 8. Both the rope-releasing component 7 and the rope-retracting component 8 are installed on the outer surface of the side plate 2 3. The rope-releasing component 7 is used to store and release the binding rope to achieve a continuous supply of binding rope. The rope-retracting component 8 is used to pull and tighten the binding rope, and cooperate with the compaction process to complete the automatic binding of the carton board, reducing manual rope threading and rope retraction operations.

[0021] Example 2, based on Example 1, please refer to... Figure 6-7 As shown, the compaction mechanism 6 includes a hydraulic cylinder 61, which is fixedly installed on the top of the top plate 5. A telescopic rod 62 is fixedly connected to the telescopic end of the hydraulic cylinder 61. The telescopic rod 62 passes through the top plate 5 and extends to its bottom. A pressure plate 63 is fixedly installed at the bottom of the telescopic rod 62. The hydraulic cylinder 61 drives the telescopic rod 62 to extend and retract, thereby causing the pressure plate 63 to move vertically up and down. The pressure plate 63 is used to directly squeeze the cardboard to achieve material compaction and shaping. A rope groove 64 is provided at the bottom of the pressure plate 63. The rope groove 64 is used to accommodate the binding rope above the cardboard, preventing the rope from being squeezed and damaged during the compaction process of the pressure plate 63. The rope groove 64 is located directly above the rope groove 47 to ensure accurate alignment of the upper and lower ropes and achieve complete wrapping of the cardboard. A limiting component 66 is installed inside the rope groove 64. The limiting component 66 is used to elastically limit the rope in the rope groove 64 to prevent the rope from coming out of the rope groove 64. At the same time, it can automatically open during unloading to facilitate the rope's release. Guide posts 65 are fixedly installed at the four corners of the top of the pressure plate 63. The guide posts 65 are slidably installed on the surface of the top plate 5. The guide posts 65 are used to guide and limit the lifting and lowering movement of the pressure plate 63, so as to prevent the pressure plate 63 from deviating during the lifting and lowering process and ensure that the compaction operation is carried out smoothly. The limiting component 66 includes a fixing rod 661, which is fixedly installed on both sides inside the rope groove 64. An arc-shaped limiting plate 662 is rotatably installed on the outer surface of the fixing rod 661. The inner curved surface of the arc-shaped limiting plate 662 directly contacts the binding rope 73 to limit and block the rope. A slot 663 is provided at the edge of the arc-shaped limiting plate 662 to increase the contact area with the binding rope and improve the limiting effect. A torque spring 664 is fixedly connected between the arc-shaped limiting plate 662 and the fixing rod 661. The torque spring 664 is sleeved on the outer surface of the fixing rod 661 and provides elastic torque to the arc-shaped limiting plate 662. Under normal conditions, it pushes the arc-shaped limiting plate 662 to close and limit the rope. When compressed, the arc-shaped limiting plate 662 elastically opens to facilitate the rope's release. The slots 663 are evenly distributed on the surface of the arc-shaped limiting plate 662. The slots 663 on the two arc-shaped limiting plates 662 are staggered and matched with each other. The staggered slots 663 improve the reliability of the limiting.

[0022] Example 3, based on Examples 1 and 2, please refer to... Figure 8-10 As shown, the rope release component 7 includes a release frame 71, which is fixedly installed on the side of the frame 1 near the side plate 3. A release drum 72 is rotatably installed inside the release frame 71, and a binding rope 73 is wound on the outer surface of the release drum 72. The release drum 72 can rotate freely to achieve smooth release of the binding rope 73. The inside of the unwinding frame 71 is equipped with a rope-passing frame 74. Pneumatic cutters 75 are installed on both the upper and lower sides of the rope-passing frame 74. The pneumatic cutters 75 are used to cut the binding rope 73 simultaneously after the binding is completed, so as to achieve automatic rope cutting. The rope winding component 8 includes a winding frame 81, which is fixedly installed on the outer surface of the frame 1 and positioned directly above the unwinding frame 71. A second motor 82 is fixedly installed on the outer surface of the winding frame 81, and a rotating shaft 83 is fixedly connected to the output end of the second motor 82. The rotating shaft 83 is rotatably installed inside the winding frame 81. A rotating drum 84 is fixedly installed on the outer surface of the rotating shaft 83, and an elastic pressure band 85 is fixedly installed on the outer surface of the rotating drum 84. The second motor 82 drives the rotating shaft 83 to rotate, which in turn drives the rotating drum 84 to rotate synchronously. The rotating drum 84 is used to drive the elastic pressure band 85 to rotate, thereby achieving rope traction. The elastic pressure band 85 uses its own elasticity to squeeze and fix the end of the binding rope 73, preventing the binding rope 73 from loosening during rope winding. The elastic pressure band 85 is set parallel to the axis of the rotating drum 84, and the elastic pressure band 85 is evenly distributed along the axis of the rotating drum 84. The elastic pressure band 85 clamps multiple binding ropes 73 to ensure that the cardboard is evenly bound. The movable end of the binding rope 73 is squeezed and matched with the elastic pressure band 85 to achieve fixed clamping of the rope body and ensure smooth rope winding operation. The binding rope 73 is sequentially passed through the rope frame 74, the rope hole 9, the rope placement groove 47 and the rope threading groove 64 so that the binding rope 73 completely wraps the cardboard box to be packed.

[0023] In use, the L-shaped feeding plate 41 in the feeding mechanism 4 is in a horizontal state with the feeding surface facing upward. The operator puts the waste cardboard into the feed port above the L-shaped feeding plate 41. At this time, the binding rope 73 is pre-wound on the unwinding drum 72 of the rope unwinding component 7. Its movable end passes through the rope frame 74, the rope hole 9, the rope groove 47 on the L-shaped feeding plate 41 and the rope threading groove 64 at the bottom of the pressure plate 63 in sequence. The part of the binding rope 73 located in the rope groove 47 is clamped and limited by the rope clamping strips 48 at both ends. The part located in the rope threading groove 64 is limited and fixed by the arc-shaped limiting plate 662 in the limiting component 66. After the movable end of the binding rope 73 passes through the rope hole 9, it is squeezed and fixed by the elastic pressure band 85 on the rotating drum 84 in the rope winding component 8. After the cardboard is fed, the hydraulic cylinder 61 is started. The hydraulic cylinder 61 drives the telescopic rod 62 to extend downward, which drives the pressure plate 63 to move vertically downward. The guide posts 65 at the four corners of the top of the pressure plate 63 slide synchronously along the top plate 5 to ensure that the pressure plate 63 presses down smoothly and squeezes and compacts the waste cardboard on the L-shaped material plate 41. At the same time, the second motor 82 is started. The second motor 82 drives the rotating shaft 83 to rotate, which drives the rotating drum 84 and the elastic pressure belt 85 to rotate synchronously. The elastic pressure belt 85 and the binding rope 73 are pulled by friction to tighten the rope, so that the binding rope 73 tightly wraps the compacted cardboard. After the cardboard is pressed into place, the pneumatic cutter 75 is activated. The two pneumatic cutters 75 move synchronously and relative to each other, cutting the binding rope 73. The operator only needs to tie a simple knot at the end of the binding rope 73 to complete the packaging. Subsequently, the hydraulic cylinder 61 is controlled to drive the telescopic rod 62 to retract upward, and the pressure plate 63 moves upward accordingly. During the upward movement of the pressure plate 63, the binding rope 73 exerts a squeezing force on the arc-shaped limiting plate 662, which overcomes the elastic torque of the torque spring 664 and pushes the arc-shaped limiting plate 662 to rotate around the fixed rod 661 and open, so that the binding rope 73 can be smoothly moved out of the rope groove 64. Start motor 45, which drives gear 46 to rotate. Through gear meshing, gear 44 at both ends of rotating rod 43 rotates, which in turn drives rotating rod 43 and L-shaped material plate 41 to rotate slowly by 90 degrees. This makes the material placement surface of L-shaped material plate 41 gradually perpendicular to the ground. The packaged carton is sent out of frame 1 under the action of gravity. During the process of removing the carton, the binding rope 73 is pulled and disengages from the rope clips 48 at both ends of rope groove 47, completing the entire carton packaging and unloading process.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
