Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper production, in particular to a blanking mechanism of a cardboard slotting machine. Background Art

[0002] In the process of producing corrugated cardboard into products, in order to facilitate the subsequent stacking of the cardboard, processes such as slotting, trimming and creasing are often required. In the existing technology, cardboard slotting, trimming and creasing are usually achieved through cardboard slotting machines.

[0003] When unloading the existing cardboard slotting machine, the staff will place the pallet on the unloading end of the conveyor belt. The cardboard on the conveyor belt will fall onto the pallet in turn and will be automatically stacked on the pallet to facilitate the staff to carry the corrugated cardboard. However, due to the height limitation of the conveyor belt, the height of the cardboard stack cannot exceed the height of the conveyor belt, resulting in the staff needing to frequently remove the corrugated paper from the pallet, which additionally increases the workload of the staff. If the height of the conveyor belt is increased, the initial position of the cardboard will be higher, and the cardboard will flutter when falling onto the pallet, affecting the normal stacking of subsequent cardboards.

[0018] In order to more clearly illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of the present invention. For ordinary technicians in this field, without paying any creative work, other embodiments can be obtained based on these drawings and embodiments, which all fall within the scope of protection of the present invention.

[0019] according to Figure 1-4 As shown, a unloading mechanism of a cardboard slotting machine includes a gantry 1, a lifting frame 2 is installed on the gantry 1 in a liftable manner, a lifting assembly for driving the lifting frame 2 to move is provided on the gantry 1, a fixed frame 3 is hingedly installed on the lifting frame 2, a connecting rod 4 is slidably installed on the end of the fixed frame 3 away from the lifting frame 2, a first belt roller 5 is rotatably installed on the connecting rod 4, both ends of the first belt roller 5 are rotatably installed on the first bearing seat 6, the first bearing seat 6 is fixedly installed on the ground, a second belt roller 7 is rotatably installed on the end of the fixed frame 3 close to the lifting frame 2, a plurality of groups of first conveyor belts 8 are cooperated and installed between the first belt roller 5 and the second belt roller 7, and a horizontal conveying assembly is provided on the side of the first belt roller 5 away from the fixed frame 3.

[0020] In this embodiment, the lifting assembly includes two groups of transmission rods 9, which are rotatably mounted on the upper and lower ends of the gantry 1 through bearings. Sprockets 10 are fixedly mounted at both ends of the transmission rods 9. The sprockets 10 on the same side are connected to each other through chains 11. The lifting frame 2 is fixedly connected to the chain 11. A first motor 12 is fixedly mounted on the lower end of the gantry 1. The power output shaft of the first motor 12 is fixedly connected to the transmission rod 9 through a coupling. The gantry 1 is mounted on the inner side of the gantry 1 through a guide rail slider assembly. The transmission rod 9 is driven to rotate by the first motor 12, and the sprocket 10 rotates synchronously with the transmission rod 9, thereby driving the lifting frame 2 to rise or fall through the chain 11. When the lifting frame 2 moves, it will drive the fixed frame 3 to move synchronously, thereby adjusting the unloading height of the cardboard.

[0021] In this embodiment, a waist-shaped hole 13 is provided on the side wall of one end of the connecting rod 4 close to the fixing frame 3, and a limiting rod 14 is installed in the waist-shaped hole 13. The limiting rod 14 is fixedly installed on the fixing frame 3. When the lifting frame 2 drives the fixing frame 3 to move, relative sliding will occur between the fixing frame 3 and the connecting rod 4. The fixing frame 3 is limited by the limiting rod 14 in conjunction with the waist-shaped hole 13, thereby limiting the adjustment range of the fixing frame 3.

[0022] In this embodiment, the horizontal conveying assembly includes a second bearing seat 15, and the second bearing seat 15 and the first bearing seat 6 are connected to each other through a connecting plate 16. A third belt roller 17 is rotatably installed on the top of the second bearing seat 15, and several groups of second conveyor belts 18 are installed between the third belt roller 17 and the first belt roller 5. Several groups of second conveyor belts 18 are staggered with the first conveyor belt 8.

[0023] In this embodiment, a second motor 19 is fixedly mounted on the first bearing seat 6, and a power output shaft of the second motor 19 is fixedly connected to the first belt roller 5. Elastic telescopic rods 20 are fixedly mounted on the front and rear ends of the bottom of the fixed frame 3, and mounting seats 21 are fixedly mounted on the ends of the elastic telescopic rods 20. Tensioning rollers 22 are rotatably mounted on the two groups of mounting seats 21 through bearings. The first conveyor belt 8 is cooperatively mounted on the periphery of the tensioning roller 22. When the fixed frame 3 and the connecting rod 4 slide relative to each other, the first conveyor belt 8 is always in a tensioned state through the tensioning roller 22, and the first belt roller 5 is driven to rotate by the second motor 19. Under the action of the first conveyor belt 8 and the second conveyor belt 18, the first belt roller 5 will drive the second belt roller 7 and the third belt roller 17 to rotate synchronously. The cardboard is placed on the conveyor belt, and the cardboard is transported toward the gantry 1 through the conveyor belt.

[0024] In this embodiment, support rods 23 are slidably installed at the front and rear ends of the lifting frame 2, and a baffle plate 24 is fixedly installed at one end of the two groups of support rods 23 away from the fixed frame 3. An electric telescopic rod 25 is fixedly installed on the top of the lifting frame 2, and the power output end of the electric telescopic rod 25 is fixedly connected to the baffle plate 24. The baffle plate 24 plays a limiting role. After the cardboard contacts the baffle plate 24, it falls vertically onto the support plate, avoiding the cardboard flying forward due to inertia, improving the stability of the cardboard during unloading, and controlling the distance between the baffle plate 24 and the fixed frame 3 by the electric telescopic rod 25 to be suitable for cardboards of different widths.

[0025] When the present invention is in use, the cardboard processed by the slotting machine is transported to the second conveyor belt 18. Under the drive of the second motor 19, the second conveyor belt 18 cooperates with the first conveyor belt 8 to transport the cardboard in the direction of the baffle plate 24. A pallet is placed under the baffle plate 24. After the cardboard contacts the baffle plate 24, it falls vertically onto the support plate. As the number of cardboards stacked on the pallet increases, the first motor 12 drives the sprocket 10 to rotate, and the cooperation of the sprocket 10 and the chain 11 causes the lifting frame 2 to gradually rise. When the lifting frame 2 rises, the discharge end of the fixed frame 3 rises synchronously, thereby adjusting the unloading height of the cardboard, thereby increasing the stacking height of the cardboard, reducing the number of times the cardboard is handled, and effectively reducing the workload of the staff.

[0026] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the scope of the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the spirit and scope of protection of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the scope of protection of the present invention.
