Description

Technical Field

[0001] The utility model belongs to the technical field of die-cutting devices, and in particular relates to a die-cutting device for adaptive corrugated paperboards. Background Art

[0002] Corrugated paper or corrugated board is a packaging material consisting of corrugated board and one or two flat linerboards. It is manufactured on a flute laminator or corrugator and is used to make corrugated boxes. In the process of processing corrugated board, in order to form different shapes of corrugated board, it will be embossed, die-cut and other operations. In many die-cutting devices, many of them use die-cutting rollers assembled on rotating rollers for rotary cutting and embossing operations. When embossing and die-cutting different sizes of cardboard, in order to avoid replacing die-cutting rollers, the embossing parts and cutting parts are separated from the rotating rollers. Different types of cardboards can be produced by adjusting the positions of the embossing parts and cutting parts;

[0003] For example, a Chinese patent with patent number CN220219856U discloses an efficient die-cutting device for adaptive corrugated cardboard, including an assembly roller, on which a side cutting piece, a first creasing piece and a second creasing piece are movably and adjustably arranged on the peripheral side wall of the assembly roller; a clamping assembly for synchronously fixing the side cutting piece, the first creasing piece and the second creasing piece is arranged on the inner side wall of the assembly roller, and an adjusting assembly for adjusting the clamping assembly is arranged inside one end of the assembly roller, so as to solve the problem that the die-cutting blade and the creasing sheet on the traditional die-cutting roller are mostly fixed on the die-cutting roller, that is, a die-cutting roller is only suitable for processing a carton of one specification and model. When it is necessary to process cartons of other specifications and models, the die-cutting roller needs to be disassembled as a whole, and then another corresponding die-cutting roller is assembled, which leads to the problem of low processing efficiency; however, in the prior art, each time the position of the cutting piece and the creasing piece is adjusted, the cutting piece and the creasing piece need to be reassembled, and the operation is complicated.

[0021] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1-3 As shown, a die-cutting device for adaptive corrugated cardboard includes an assembling roller 1 and four motors 2, wherein mounting plates 12 are fixedly connected at both ends of the assembling roller 1, a cylinder 13 with four mounting grooves 131 is fixedly connected between the two mounting plates 12, the four mounting grooves 131 are arranged in a circular array, four lead screws 21 assembled and connected with the mounting plates 12 are arranged in the cylinder 13, the four lead screws 21 are arranged in a circular array, the output shaft of the motor 2 is drivingly connected with the lead screws 21, two lead screws 21 are assembled and connected with indentation parts 3, and the other two lead screws 21 are assembled and connected with die-cutting parts 4, and a mounting groove 131 of the cylinder 13 is slidably connected with the indentation part 3 or the die-cutting part 4.

[0023] By adopting the technical solution of this embodiment, four motors 2 are used to individually control the rotation of four screws 21. When the screws 21 rotate, the creasing part 3 and the die-cutting part 4 are driven to move, thereby realizing automatic control of the movement of the creasing part 3 and the die-cutting part 4. There is no need to adjust the position of the creasing part 2 and the die-cutting part 4 and reassemble the creasing part 2 and the die-cutting part 4, which is simple to operate.

[0024] Reference Figure 2 : Two creasing parts 3 are located on opposite sides, and two die-cutting parts 4 are located on opposite sides.

[0025] In this embodiment, the two creasing pieces 3 and the die-cutting piece 4 are arranged opposite to each other. When the assembling roller rotates, the creasing piece 3 and the die-cutting piece 4 can work more stably.

[0026] Reference Figure 2-3 : The indentation part 3 and the die-cutting part 4 both include a working part and a connecting part. The inner sides of the working parts of the indentation part 3 and the die-cutting part 4 are slidably connected to the cylinder 13. The connecting parts of the indentation part 3 and the die-cutting part 4 are threadedly connected to the lead screw 21. The connecting parts of the indentation part 3 and the die-cutting part 4 slide in the mounting groove 131.

[0027] In this embodiment, the working parts of the creasing member 3 and the die-cutting member 4 are used to creasing and cutting the corrugated paper respectively, the lead screw 21 is used to drive the creasing member 3 and the die-cutting member 4 to move respectively, and the mounting groove 131 is used to prevent the creasing member 3 and the die-cutting member 4 from rotating.

[0028] Reference Figure 3 : The working parts of the impression piece 3 and the die-cutting piece 4 are both quarter arcs.

[0029] In this embodiment, since the working parts of the creasing piece 3 and the die-cutting piece 4 are both quarter arcs, the creasing piece 3 and the die-cutting piece 4 can move freely when they move without being restricted by the other creasing pieces 3 and the die-cutting pieces 4.

[0030] Reference Figure 1 : A connecting cover 14 is provided on the outer side of the two mounting plates 12, and the edge of the connecting cover 14 is fixedly connected to the cylinder 13.

[0031] Reference Figure 1 : Both ends of the assembly roller 1 are fixedly connected with a mounting shaft 15, and the mounting shaft 15 is arranged in the middle of the connecting cover 14.

[0032] In this embodiment, the installation shaft 15 is used to drive the assembly roller 1 to rotate.

[0033] Working principle: Two die-cutting pieces 4 can be located on the same line. When the mounting shaft 15 drives the assembly roller 1 to rotate, the die-cutting pieces 4 located at the same position can cut the same cutting position. When the two creasing pieces 3 are located on the same line, when the assembly roller 1 rotates, the folds on a line of the corrugated cardboard are processed. When the two die-cutting pieces 4 are located at different positions, the die-cutting pieces 4 process both sides of the corrugated paper. When the creasing pieces 3 are located at two different positions, the two creasing pieces 3 perform creasing processing on two positions of the corrugated paper.

[0034] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0035] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical ideas disclosed in the present invention shall still be covered by the claims of the present invention.
