Description

Technical Field

[0001] This invention relates to the field of corrugated cardboard processing, and more particularly to an automatic handling device for corrugated cardboard. Background Technology

[0002] Corrugated cardboard, due to its excellent cushioning properties, high strength, and lightweight and low cost, is widely used in packaging, logistics, and other industries, and is an important material for transport packaging of various products. With the continuous growth of market demand for packaging products, the production and use of corrugated cardboard are expanding daily. Handling corrugated cardboard has become an indispensable and crucial link in production, warehousing, and transportation.

[0003] In traditional corrugated cardboard handling, stacks of corrugated cardboard are transported to their target location by conveyor rollers. However, the subsequent handling after leaving the conveyor rollers largely relies on manual labor or simple handling tools such as forklifts. Manual handling is not only inefficient and labor-intensive, but also prone to worker fatigue during prolonged handling, leading to errors and increasing the risk of damage to the corrugated cardboard, thus affecting product quality and production schedule. While using simple handling tools like forklifts improves handling efficiency to some extent, some stacks of corrugated cardboard are directly piled on the ground, making it difficult to directly insert the forklift's levers, thus directly limiting the handling process. It is difficult to accurately clamp, move, and place the corrugated cardboard, and improper operation may also cause damage such as squeezing or collision. In addition, traditional handling methods lack flexibility in complex working environments, such as narrow spaces or multi-workstation scenarios, and cannot meet the needs of modern efficient production and logistics.

[0015] Compared with related technologies, the automatic handling device for corrugated cardboard provided by the present invention has the following advantages:

[0016] 1. This invention uses a hydraulic cylinder to move a rack plate, which cooperates with the main gear to tilt the overall clamping frame. The sliding groove, sliding strip and embedded cam of the limiting side seat work together to ensure a smooth tilting process and prevent deviation and shaking. It can be conveniently inserted into the bottom of the tilted corrugated cardboard, which facilitates subsequent handling and reduces the risk of damage to the corrugated cardboard due to unstable tilting.

[0017] 2. This invention can quickly adjust the spacing between the clamping plates by adjusting the rotation of the drive shaft driven by the motor. The cooperation between the stabilizing plate, the stabilizing tube, and the limiting rod ensures that the clamping plate moves accurately and can firmly hold corrugated cardboard of different sizes. This adaptive clamping design avoids the tediousness of manual adjustment and greatly improves the convenience and efficiency of clamping operation, adapting to the handling needs of corrugated cardboard of various specifications.

[0018] 3. This invention uses the movement of the clamping plate to bring the clamping plates on the front locking frame closer together, the plug and slot cooperate, the latch and spring achieve quick locking, and the electromagnet controls the unlocking. The whole process is efficient and fast. Compared with the traditional locking method, this structure can complete the construction and release of the clamping frame in a short time, ensuring that the corrugated cardboard is stable and does not loosen during the handling process, thus improving the safety and reliability of handling.

[0019] 4. The present invention uses the threaded connection between the adjusting shaft and the tensioning plate to flexibly adjust the relative locking position between the two tensioning plates during the pre-preparation work, so that it can adapt to corrugated cardboard stacks of different widths without replacing parts, thereby enhancing the versatility and flexibility of the device and effectively reducing the cost of use and the difficulty of operation.

[0020] 5. This invention uses a secondary motor to drive the shaft to rotate, causing the combined bottom support plate to slide within the stabilizing frame, thereby achieving adjustment in combination with the opposing seat. This facilitates the placement of the main corrugated cardboard and makes subsequent direct handling easier. This precise bottom support design enhances the overall support effect on the corrugated cardboard, ensures the integrity of the cardboard during handling, and improves handling efficiency and quality.

[0021] 6. This invention uses a hidden motor to drive a drive gear that meshes with a gear plate, enabling the handling device to turn. This facilitates the handling and placement of corrugated cardboard in different locations, while also allowing the device to operate flexibly in complex environments. This greatly expands the handling range, improves the flexibility and convenience of the work, and reduces the labor intensity of manual handling. Attached Figure Description

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] Please refer to the following: Figures 1 to 9An automatic handling device for corrugated cardboard includes: a base 1, a mating seat 2 on the base 1, an inclined backrest 3 fixedly connected to the mating seat 2, a bottom crossbeam 31 at the front of the inclined backrest 3, a backrest 32 fixedly connected to the middle of the bottom crossbeam 31, and clamping plates 33 at both ends of the bottom crossbeam 31, with front locking frames 34 fixedly connected to both ends of the clamping plates 33; and an inclined loading mechanism, which includes two main shafts 4, with the two bottom crossbeams 31 respectively connected to the bottom... The two ends of the crossbeam 31 are fixedly connected, and the two main shafts 4 are each fixedly connected with a main gear 41. The two main gears 41 are each provided with a rack plate 42 on their lower side. The two rack plates 42 mesh with the two main gears 41 respectively. The two side walls of the mating seat 2 are each installed with a hydraulic cylinder 43. The telescopic ends of the two hydraulic cylinders 43 are respectively fixedly connected to one end of the two rack plates 42. An adjustment component is provided between the two clamping plates 33 and the bottom crossbeam 31. A reinforcing locking component is provided between the two front locking frames 34.

[0034] In the specific implementation process, such as Figure 2 and Figure 3 As shown, limiting side seats 44 are fixedly connected to both side walls of the mating seat 2. Slide grooves are provided on both inner walls of the two limiting side seats 44. Slide bars are provided on both side walls of the two rack plates 42. The two slide bars are slidably connected to the slide grooves on both sides. Multiple mounting grooves are provided on the side walls of the two slide bars. Embedded cams 45 are installed in the multiple mounting grooves. The multiple embedded cams 45 abut against the inner walls of the slide grooves on both sides in pairs.

[0035] It should be noted that: the extension end of the hydraulic cylinder 43 pushes the rack plate 42 to slide relative to the limit side seat 44. Since the rack plate 42 meshes with the main gear 41, it drives the main shaft 4 to rotate, thereby realizing the tilting action of the overall clamping frame. It can tilt the corrugated cardboard stack to a certain angle so that the combined bottom support plate 81 can be inserted into its bottom for easy subsequent moving.

[0036] The limiting side seat 44, the slide groove, the slide bar, and the embedded cam 45 together constitute the guiding and stabilizing structure of the tilting upper plate mechanism. When the hydraulic cylinder 43 pushes the rack plate 42 to move, the sliding cooperation between the slide bar and the slide groove can ensure that the rack plate 42 moves smoothly along the predetermined direction and prevent it from shifting laterally. The embedded cam 45 abuts against the inner wall of the slide groove, which can adjust the posture of the rack plate 42 in real time during the movement, reduce the shaking caused by uneven force, and further improve the stability and reliability of the tilting action, providing a stable operating basis for inserting the combined bottom support plate 81 into the bottom of the tilted corrugated cardboard.

[0037] refer to Figure 3 and Figure 4As shown, the adjustment assembly includes a built-in crossbar 5, a horizontal cavity inside the bottom crossbeam 31, the built-in crossbar 5 being fixedly installed in the horizontal cavity, lugs 51 being fixedly connected to one end of each of the two retaining plates 33, a main opening groove being provided on the front wall of the horizontal cavity, one end of each of the two retaining plates 33 being slidably connected to the two ends of the main opening groove, a secondary opening groove being provided on the upper wall of the horizontal cavity, two lugs 51 being slidably connected to the two ends of the secondary opening groove, side lug seats 52 being fixedly connected to both ends of the bottom crossbeam 31, a drive shaft 53 being rotatably connected between the two side lug seats 52, the two ends of the drive shaft 53 being provided with threads in opposite directions, the two lugs 51 being threadedly connected to the two ends of the drive shaft 53, an adjustment motor 54 being installed and connected to one end of the bottom crossbeam 31, and the output end of the adjustment motor 54 being fixedly connected to the drive shaft 53.

[0038] It should be noted that when the adjusting motor 54 drives the drive shaft 53 to rotate, since the threads at both ends of the drive shaft 53 are in opposite directions, after being threadedly connected to the lug 51, the two clamping plates 33 can move synchronously inward or outward. The built-in crossbar 5 plays a role in supporting and stabilizing the lug 51, preventing the lug 51 from tilting or getting stuck during movement. The main opening slot and the secondary opening slot provide guiding space for the movement of the clamping plate 33 and the lug 51, ensuring that the clamping plate 33 can be accurately adjusted to the appropriate position, thereby firmly holding corrugated cardboard of different sizes and improving the adaptability of the device to corrugated cardboard of different specifications.

[0039] refer to Figure 2 and Figure 3 As shown, both ends of the bottom crossbeam 31 are fixedly connected to a stabilizing plate 55, and multiple stabilizing tubes 56 are fixedly connected to each of the two stabilizing plates 55. Multiple limiting rods 57 are fixedly connected to each of the two retaining plates 33, and the multiple limiting rods 57 are slidably connected to the multiple stabilizing tubes 56 respectively.

[0040] It should be noted that the stabilizing plate 55, the stabilizing tube 56, and the limiting rod 57 further enhance the stability of the clamping plate 33 during its movement. When the clamping plate 33 adjusts the spacing through the adjusting component, the limiting rod 57 slides within the stabilizing tube 56, which can limit the displacement of the clamping plate 33 in the direction perpendicular to the movement direction and prevent the clamping plate 33 from shaking or shifting.

[0041] refer to Figure 5 and Figure 6 As shown, the reinforcing locking assembly includes two clamping plates 6. One end of the clamping plate 6 is provided with a plug 61, and the other end of the clamping plate 6 is provided with a slot 62. Both sides of the plug 61 are provided with slots, and both sides of the slot 62 are provided with mounting positions. Short cylinders 63 are installed and connected in both mounting positions.

[0042] It should be noted that the reinforcing locking assembly is a key structure to ensure the stability of the corrugated cardboard during handling. The two clamping plates 6 are initially connected by the cooperation of the plug 61 and the slot 62. This plug-in method is simple and quick to operate, and can quickly build an initial clamping frame after the clamping plate 33 clamps the corrugated cardboard. The short tube 63 serves as the mounting carrier for components such as the clamp head 65, providing basic structural support for the subsequent locking action.

[0043] refer to Figure 6 and Figure 8 As shown, a stop rod 64 is slidably connected to one end of the short cylinder 63. A clamp head 65 is fixedly connected to one end of the stop rod 64. The clamp head 65 is a wedge-shaped head. A magnetic plate 66 is fixedly connected to the other end of the stop rod 64. A spring 67 is sleeved on the stop rod 64. An electromagnet 68 is installed and connected to the inner wall of the other end of the short cylinder 63. The magnetic poles of the electromagnet 68 and the magnetic plate 66 are opposite.

[0044] It should be noted that: spring 67, magnetic plate 66, electromagnet 68 and locking head 65 constitute an automatic locking and unlocking system. When plug 61 is inserted into slot 62, wedge-shaped locking head 65 is squeezed and retracted by plug 61. After plug 61 is fully inserted, spring 67 restores its elastic deformation and pushes locking head 65 into the slots on both sides of plug 61, so as to achieve a firm locking of the two clamping plates 6 and make the clamping frame more stable.

[0045] When it is necessary to unlock, the electromagnet 68 is energized, and an attraction is generated between the electromagnet 68 and the magnetic plate 66. The magnetic plate 66 is attracted to move the stop rod 64 and the locking head 65, causing the locking head 65 to slide out of the slot, thereby unlocking quickly. The operation is convenient and efficient, and it is convenient for loading and unloading corrugated cardboard.

[0046] refer to Figure 6 and Figure 7 As shown, each of the two front locking frames 34 has a horizontal right-angle seat 7 fixedly connected to its side wall. Each of the two horizontal right-angle seats 7 has a stabilizing port at one end. The two tensioning plates 6 are slidably connected to the two stabilizing ports respectively. Each of the two horizontal right-angle seats 7 has a short rod 71 fixedly connected to its side wall. Each of the two tensioning plates 6 is slidably connected to the two short rods 71 ​​respectively. Each of the two horizontal right-angle seats 7 has an adjusting shaft 72 rotatably connected to its side wall. Both adjusting shafts 72 are threaded rods. Each of the two tensioning plates 6 has a threaded port at one end. The two tensioning plates 6 are threadedly connected to the two adjusting shafts 72 respectively. A turntable 73 is installed and connected to one end of the adjusting shaft 72.

[0047] It should be noted that the threaded connection between the adjusting shaft 72 and the tensioning plate 6 allows for flexible adjustment of the relative position of the tensioning plate 6. During preparatory work, rotating the adjusting shaft 72 can cause the tensioning plate 6 to slide along the short rod 71 and the stabilizing opening, thereby changing the relative locking position between the two tensioning plates 6. This design can adapt to corrugated cardboard stacks of different widths without the need to replace parts, improving the versatility and flexibility of the device.

[0048] refer to Figure 1 and Figure 9 As shown, a stabilizing frame 8 is fixedly connected to the side wall of the mating seat 2. One side of the stabilizing frame 8 is provided with an inlet and outlet, and a combined bottom support plate 81 is slidably connected to the inlet and outlet. A counter seat 811 is fixedly connected to the other side wall of the mating seat 2. The counter seat 811 is provided with a flat opening. Adjusting blocks 82 are fixedly connected to both ends of the combined bottom support plate 81. Long through slots 83 are provided on both sides of the stabilizing frame 8. A stabilizing rod 84 is fixedly connected to one long through slot 83, and a push shaft 85 is rotatably connected to the other long through slot 83. The push shaft 85 is a threaded rod. One end of the adjusting block 82 is slidably connected to the stabilizing rod 84, and the other end of the adjusting block 82 is threadedly connected to the push shaft 85. An auxiliary motor 86 is installed and connected to one side wall of the stabilizing frame 8. The output end of the auxiliary motor 86 is fixedly connected to the push shaft 85.

[0049] It should be noted that the combined bottom support plate 81, stabilizing frame 8, push shaft 85, and auxiliary motor 86 work together to support the bottom of the corrugated cardboard. After the corrugated cardboard is tilted by the clamping frame, the auxiliary motor 86 is started to drive the push shaft 85 to rotate. Since the push shaft 85 is threadedly connected to the adjusting block 82 and the adjusting block 82 is slidably engaged with the stabilizing rod 84, the combined bottom support plate 81 can slide smoothly at the inlet and outlet of the stabilizing frame 8. One end of it can be accurately inserted into the flat opening of the opposing seat 811. This design can enhance the overall support effect of the corrugated cardboard, ensure the integrity of the cardboard during handling, and improve handling efficiency and quality.

[0050] refer to Figure 1 and Figure 2 As shown, a rotating column 9 is rotatably connected to the base 1. The upper end of the rotating column 9 is fixedly connected to the mating seat 2. A gear plate 91 is fixedly connected to the rotating column 9. A hidden motor 92 is installed and connected in the base 1. A drive gear 93 is fixedly connected to the output end of the hidden motor 92. The drive gear 93 meshes with the gear plate 91.

[0051] It should be noted that the hidden motor 92, drive gear 93, gear plate 91, and rotating column 9 constitute the steering system of the handling device. When it is necessary to adjust the direction of the corrugated cardboard stack, the hidden motor 92 is started, and its output end drives the drive gear 93 to rotate. The drive gear 93 meshes with the gear plate 91, which in turn drives the rotating column 9 to rotate. Since the upper end of the rotating column 9 is fixedly connected to the mating seat 2, the entire handling device can achieve steering, enabling the device to flexibly handle corrugated cardboard in different positions and different working environments. Especially in narrow spaces or multi-workstation operation scenarios, it greatly expands the handling range, reduces the labor intensity of manual handling, and improves the flexibility and convenience of work.

[0052] The working principle of the automatic handling device for corrugated cardboard provided by the present invention is as follows: When it is necessary to handle stationary corrugated cardboard, two clamping plates 33 are inserted into both sides of the corrugated cardboard stack. The adjusting motor 54 is started, and its output end drives the drive shaft 53 to rotate. The two ends of the drive shaft 53 are provided with threads in opposite directions and are threadedly connected to the lugs 51. As the drive shaft 53 rotates, the two lugs 51 drive the two clamping plates 33 to slide along the main opening groove on the front side of the bottom crossbeam 31, thereby realizing the adjustment of the spacing between the clamping plates 33. The stabilizing tube 56 on the stabilizing plate 55 is slidably connected to the limiting rod 57 on the clamping plate 33, which further stabilizes and guides the movement of the clamping plates 33, ensuring that the clamping plates 33 can be accurately adjusted to the appropriate position and firmly hold both sides of corrugated cardboard of different sizes.

[0053] Simultaneously, the two retaining plates 33 drive the two front locking frames 34 to move together, causing the tensioning plates 6 on the two front locking frames 34 to move closer to each other. The plug 61 on one tensioning plate 6 slides into the slot 62 on the other tensioning plate 6. When the plug 61 slides to the point where the inclined surfaces of the two locking heads 65 abut against each other, the two locking heads 65 retract accordingly. After the plug 61 is fully inserted, both springs 67 restore their elastic deformation, causing the two locking heads 65 to reset and move into the slots on the side walls of the plug 61, thus realizing the insertion... During the connection process, the two clamping plates 6 are quickly locked, forming a stable clamping frame between them and the two clamping plates 33, which facilitates further tilting of the corrugated cardboard stack to assist in bottom support. When it is necessary to release the lock, the two electromagnets 68 are energized. The electromagnets 68 and the magnetic plate 66 have opposite magnetic poles, generating an attraction force, which attracts the magnetic plate 66 to move the abutment rod 64 and the locking head 65. The locking head 65 then slides out of the slots on both sides of the plug 61, thus realizing the quick unlocking of the two clamping plates 6, which is very convenient and efficient.

[0054] In the preparatory work, the adjusting shaft 72 can be rotated. Since the adjusting shaft 72 is a threaded rod, it is threadedly connected to the threaded end of the tensioning plate 6. The rotation of the adjusting shaft 72 causes the two tensioning plates 6 to slide stably relative to the short rods 71 ​​in the two horizontal right-angle seats 7, thereby realizing the relative locking position between the two tensioning plates 6, so that it can be used for corrugated cardboard stacks of different widths.

[0055] The hydraulic cylinders 43 on both sides of the mating seat 2 are activated, causing their telescopic ends to push the rack plate 42 to slide relative to the limiting side seat 44. Since the rack plate 42 meshes with the main gear 41, the linear motion of the rack plate 42 is converted into the rotation of the main gear 41, which in turn drives the main shaft 4 to rotate, realizing the tilting action of the overall clamping frame. This allows the corrugated cardboard stack to be tilted at a certain angle, so that the combined bottom support plate 81 can be inserted into its bottom for easy subsequent movement. During this process, the sliding groove on the limiting side seat 44 and the sliding bar of the rack plate 42 cooperate with each other to play a guiding role, ensuring that the rack plate 42 moves smoothly. At the same time, the embedded cam 45 on the sliding bar abuts against the inner wall of the sliding groove, further improving the stability of the rack plate 42's movement and preventing it from deviating or shaking.

[0056] After the tilting action of the corrugated cardboard stack is completed, the auxiliary motor 86 is started, and its output end drives the push shaft 85 to rotate. The push shaft 85 is a threaded rod, which is threadedly connected to the threaded opening of the adjusting block 82 at one end of the combined base plate 81. At the same time, the adjusting block 82 at the other end is slidably connected to the stabilizing rod 84. As the push shaft 85 rotates, the combined base plate 81 slides at the inlet and outlet of the stabilizing frame 8, so that one end of the combined base plate 81 slides into the flat opening on the opposing seat 811, realizing the combined adjustment of the combined base plate 81 and the opposing seat 811, so as to facilitate the placement of the corrugated cardboard and facilitate subsequent direct handling.

[0057] When it is necessary to adjust the direction of the corrugated cardboard stack, the hidden motor 92 can be started directly. The output end of the hidden motor 92 drives the drive gear 93 to rotate. The drive gear 93 meshes with the gear plate 91 on the rotating column 9, thereby driving the rotating column 9 to rotate. The upper end of the rotating column 9 is fixedly connected to the mating seat 2, thereby realizing the turning of the entire handling device, which facilitates the handling of corrugated cardboard in different positions and also makes it easy to move the corrugated cardboard directly to different positions.

[0058] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
