[0001] The utility model relates to the technical field of corrugated cardboard die-cutting equipment, in particular to an anti-displacement and indentation die-cutting device for fold-resistant multi-fluted corrugated cardboard. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which is composed of at least one layer of corrugated core paper and one layer of cardboard. It has high mechanical strength and can effectively offset the force of collision and falling during transportation, better protecting the packaging. It is the material for making corrugated boxes. During production, it needs to be cut and indented to facilitate folding when making cartons.

DETAILED DESCRIPTION

[0025] The present invention will be described in further detail below with reference to the accompanying drawings.

[0026] Example:

[0027] Reference Figure 1 - Figure 5 The utility model discloses an anti-displacement and indentation die-cutting device for folding-resistant multi-flute corrugated cardboard, comprising a die-cutting plate 1, a sliding rail 2 being provided at the bottom end of the die-cutting plate 1, a sliding structure 3 being provided on the outer wall of the sliding rail 2 for sliding movement, and three groups of sliding structures 3 being provided, the sliding rail 2 being a T-shaped structure, and a die-cutting device 4 being provided on the side wall of the die-cutting plate 1;

[0028] The sliding structure 3 includes two sliding frames 31. The sliding frames 31 are provided in two groups. The sliding frames 31 slide together with the sliding rails 2. The bottom ends of the two sliding frames 31 are provided with hinge plates 32. The center of the hinge plates 32 is provided with a hinge axis 33.

[0029] A connecting shaft 5 is provided at the center of the bottom end of the die-cutting board 1, and a connecting plate 6 is rotatably provided on the outer wall of the connecting shaft 5. A telescopic rod 7 is provided at the end of the connecting plate 6. The end of the telescopic rod 7 away from the connecting plate 6 is rotatably connected to the connecting shaft 5;

[0030] An extension bracket 8 is provided on the bottom side of one end of the telescopic rod 7 away from the connecting plate 6 , and a clamping structure 9 is provided on the upper end of the extension bracket 8 .

[0031] In this embodiment, when in use, the corrugated cardboard to be grooved is placed on the upper surface of the die-cutting plate 1, and the position where the groove is to be cut is manually determined. Then, each clamping structure 9 is pushed to a position away from the groove, and the clamping structure is pressed against the upper end of the corrugated cardboard. When cutting, the clamping structure can effectively avoid blocking the position where the groove is to be cut during die-cutting, thereby effectively improving the practicality of the device.

[0032] When the clamping structure 9 is pushed to move, the sliding structure 3 moves on the surface of the sliding rail 2, and the two sliding frames 31 are hinged by the arrangement of the hinge plate 32 and the hinge shaft 33. At this time, the two sliding frames 31 can bend when passing through the rounded corners of the sliding rail 2 to facilitate passing through the rounded corners of the sliding rail 2. The two sets of sliding frames 31 can effectively improve the stability of the sliding structure 3 during movement.

[0033] By setting the telescopic rod 7, the sliding structure 3 provides a supporting force during its movement to improve the stability of the sliding structure 3. The connecting plate 6 is used to rotatably connect the telescopic rod 7 to the connecting shaft 5 to facilitate the installation of the telescopic rod 7. Figure 3 As shown, the number of connecting plates 6 and telescopic rods 7 is the same as the number of sliding structures 3 .

[0034] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the die-cutting equipment 4 includes a machine slide rail 41, two machine slide rails 41 are provided and are fixedly installed on the two side walls of the die-cutting board 1, and a die-cutting frame 42 is slidingly provided inside the machine slide rail 41. A guide rail 43 is provided between the two die-cutting frames 42, and a die-cutting tool 44 is provided inside the guide rail 43.

[0035] In this embodiment, the machine slide rail 41 is used to install the die-cutting frame 42, and the two die-cutting frames 42 are used to install the guide rail 43, and the die-cutting tool 44 is installed through the guide rail 43, so that the die-cutting tool 44 can be moved to any position above the die-cutting board 1 to facilitate the die-cutting of the cardboard.

[0036] In a further preferred embodiment of the present invention, Figure 1-5 As shown, a sliding shaft 311 is rotatably provided at the position where the sliding frame 31 contacts the sliding rail 2 , and a rotating ball 312 is provided at the bottom end of the sliding shaft 311 .

[0037] In this embodiment, the sliding shaft 311 is provided to reduce the friction between the sliding frame 31 and the sliding rail 2, and the rotating ball 312 is provided to reduce the friction between the sliding frame 31 and the step of the sliding rail 2, so that the sliding frame 31 can turn at the rounded corner of the sliding rail 2.

[0038] In a further preferred embodiment of the present invention, Figure 1-5 As shown, an air intake pipe 71 is provided on the outer wall of the telescopic rod 7 , and a pressure relief piston 72 is slidably provided inside the air intake pipe 71 .

[0039] In this embodiment, by providing the suction pipe 71, when the telescopic rod 7 is extended or retracted, the gas inside the suction pipe 71 is sucked into the telescopic rod 7, so that the telescopic rod 7 can be extended or retracted. A relatively closed cavity can be formed inside the telescopic rod 7, which can reduce the possibility of the telescopic rod 7 sucking in cardboard waste, thereby achieving the effect of increasing the service life of the telescopic rod 7.

[0040] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the clamping structure 9 includes a guide rod 91, which is connected to the extension bracket 8 by a hinge. A clamping guide rail 92 is provided inside the guide rod 91, and a clamping plate 93 is provided inside the clamping guide rail 92 for sliding. An adjusting screw 94 is provided inside the clamping guide rail 92 for rotation, and a screw hole 95 that threadably cooperates with the adjusting screw 94 is provided inside the clamping plate 93.

[0041] In this embodiment, the guide rod 91 is connected by a hinge, as shown in FIG. Figure 5 As shown, when in use, the guide rod 91 can be flipped to avoid the die-cutting mechanism, which can further reduce the influence of the clamping structure 9 on the die-cutting mechanism during cutting, thereby achieving the purpose of improving cutting efficiency. The height of the clamping plate 93 can be adjusted by adjusting the screw 94 and the screw hole 95 to facilitate clamping of the cardboard.

[0042] In a further preferred embodiment of the present invention, Figure 1-5 As shown, the four corners of the die-cutting plate 1 are all arc-shaped and coaxial with the arc corners of the corresponding sliding rails 2.

[0043] In this embodiment, the die-cutting board 1 with arc-shaped corners can avoid the problem of collision between the clamping mechanism and the top corner of the die-cutting board 1 during the rotation process.

[0044] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
