Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard processing technology, specifically to a corrugated cardboard creasing machine. Background Technology

[0002] Corrugated cardboard is a multi-layered adhesive, consisting of at least one layer of corrugated core paper. It has high mechanical strength and can withstand collisions and drops during handling. Before corrugated cardboard is processed into cartons, it needs to be creasing to facilitate cutting and folding. However, existing creasing machines have a relatively single creasing direction. When it is necessary to adjust the creasing angle, it can only be achieved by adjusting the position of the cardboard, which greatly affects the creasing effect. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a creasing machine for corrugated cardboard that can adjust the creasing angle and greatly improve the creasing efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a corrugated cardboard creasing machine, including a machine base, on which lifting cylinders are fixedly connected on both sides, a set-top box is fixedly connected to the upper end of the lifting cylinders, a rotating hole is provided on the bottom surface of the set-top box, a creasing hood is rotatably connected in the rotating hole, an angle adjustment mechanism for driving the creasing hood to rotate is provided in the set-top box, a moving block is slidably connected in the creasing hood, a moving mechanism for driving the moving block to slide is provided in the creasing hood, a creasing wheel is fixedly connected to the bottom surface of the moving block, and a moving through hole that cooperates with the creasing wheel is provided on the bottom surface of the creasing hood; a fixed air hood is fixedly connected to the bottom surface of the machine base, a high-pressure air pump is fixedly connected to the bottom surface of the fixed air hood, and a fixed air hole communicating with the fixed air hood is provided on the machine base.

[0005] As an improvement, the angle adjustment mechanism includes a gear ring fixedly sleeved on the outer wall of the indentation cover cylinder, a first motor fixedly connected inside the set-top box, and a gear meshing with the gear ring fixedly connected to the output end of the first motor.

[0006] As an improvement, the upper part of the machine platform is provided with a pressing mechanism on all four sides. The pressing mechanism includes a support plate fixedly connected to the two sides of the upper part of the machine platform, and a rotating shaft is rotatably connected between the two support plates. A second motor that drives the rotating shaft to rotate is fixedly connected to one of the support plates. Electric telescopic swing arms are fixedly connected to both ends of the rotating shaft. A pressure block is fixedly connected to the end of the electric telescopic swing arms away from the rotating shaft on both sides.

[0007] As an improvement, limit rings are fixedly connected to both the upper and lower ends of the rotating hole on the outer wall of the indentation cover cylinder.

[0008] As an improvement, the moving mechanism includes a limiting slide frame fixedly connected inside the indentation cover cylinder, the moving block being slidably connected inside the limiting slide frame, a screw being rotatably connected inside the limiting slide frame, and a third motor for driving the screw to rotate being fixedly connected to one end of the limiting slide frame.

[0009] The advantages of this utility model compared with the prior art are as follows:

[0010] (1) The corrugated cardboard that needs to be crimped can be adsorbed and fixed on the upper surface of the machine by means of a high-pressure air pump, a fixed air cover and a fixed air hole, which effectively prevents the corrugated cardboard from shifting in position during the crimping process.

[0011] (2) The crease cylinder is driven to rotate by the angle adjustment mechanism, the crease wheel is adjusted to the appropriate crease angle, and the moving mechanism is started to drive the moving block to drive the crease wheel to roll and crease. There is no need to manually position the corrugated cardboard, which greatly improves the crease efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 3As shown, a corrugated cardboard creasing machine includes a machine base 1. Lifting cylinders 2 are fixedly connected to the machine base 1 on both sides. A set-top box 3 is fixedly connected to the upper end of each lifting cylinder 2. A rotating hole 17 is provided on the bottom surface of the set-top box 3. A creasing cover 4 is rotatably connected within the rotating hole 17. Limiting rings 18 are fixedly connected to the outer wall of the creasing cover 4 at both the upper and lower ends of the rotating hole 17. An angle adjustment mechanism for driving the creasing cover 4 to rotate is provided inside the set-top box 3. The angle adjustment mechanism includes a gear ring 14 fixedly sleeved on the outer wall of the creasing cover 4. A first motor 16 is fixedly connected inside the set-top box 3. A gear 15 that meshes with the gear ring 14 is fixedly connected to the output end of the first motor 16.

[0018] A movable block 5 is slidably connected inside the indentation cover cylinder 4. The indentation cover cylinder 4 is equipped with a moving mechanism that drives the movable block 5 to slide. The moving mechanism includes a limiting slide frame 23 fixedly connected inside the indentation cover cylinder 4. The movable block 5 is slidably connected inside the limiting slide frame 23. A screw 8 is rotatably connected inside the limiting slide frame 23. A third motor 7 that drives the screw 8 to rotate is fixedly connected to one end of the limiting slide frame. An indentation wheel 6 is fixedly connected to the bottom surface of the movable block 5. The bottom surface of the indentation cover cylinder 4 is provided with a moving through hole 22 that mates with the indentation wheel 6.

[0019] A fixed air hood 19 is fixedly connected to the bottom surface of the machine base 1. A high-pressure air pump 21 is fixedly connected to the bottom surface of the fixed air hood 19. The machine base 1 is provided with a fixed air hole 20 communicating with the fixed air hood 19. A pressing mechanism is provided on all four sides of the upper end of the machine base 1. The pressing mechanism includes a support plate 9 fixedly connected to the two sides of the upper end of the machine base 1. A rotating shaft 10 is rotatably connected between the two sides of the support plate 9. A second motor 13 that drives the rotating shaft 10 to rotate is fixedly connected to one side of the support plate 9. Electric telescopic swing arms are fixedly connected to both ends of the rotating shaft 10. A pressure block 12 is fixedly connected to the end of the electric telescopic swing arms away from the rotating shaft 10 on both sides.

[0020] In practical use, the cardboard is placed on the upper end of the machine base 1. The high-pressure vacuum pump 21 is started to draw a vacuum into the fixed air cover 19, so that the corrugated cardboard is stably adsorbed on the upper end of the machine base 1 through the fixed air hole 20. The four second motors 13 are started to drive the corresponding rotating shafts 10 to rotate. The rotating shafts 10 drive the electric telescopic arm 11 to swing. At the same time, the electric telescopic arm 11 extends and retracts to adjust the length, so that the four pressure blocks 12 press on the four sides of the corrugated cardboard to prevent the corrugated cardboard from shifting position during the creasing process. The first motor 16 is started to drive the gear 15 to rotate. The gear 15 drives the corresponding gear ring 14 to rotate. The gear ring 14 drives the creasing cover 4 to rotate, so that the creasing wheel 6 is adjusted to a suitable creasing angle. When the lifting cylinders 2 on both sides are started, the creasing wheel 6 contacts the cardboard downward. The third motor 7 is started to drive the screw 8 to rotate. The screw 8 drives the moving block 5 to slide along the length direction of the moving through hole 22, so that the creasing wheel 6 slides along the upper surface of the corrugated cardboard, thus realizing the creasing process.
