Description

Technical Field

[0001] The utility model relates to the technical field of cardboard die-cutting, in particular to a die-cutting air suction device. Background Art

[0002] Since various paper packaging and decoration products such as cardboard, paper boxes, and trademarks have a certain hardness, in order to ensure the neatness and hardness after cutting, a die-cutting machine is required for die-cutting.

[0003] When the die-cutting device performs die-cutting on cardboard, due to the uneven quality of the cardboard being die-cut, the amount of paper powder generated is also different. When the quality of the cardboard is poor, a large amount of paper powder will fall off during the die-cutting process, which will not only affect the surface effect of the cardboard. At the same time, if the paper powder on the die-cutting device is not cleaned for a long time, it is easy to accumulate at places such as the indentation line, resulting in indentation bursting and other problems, affecting the normal use of the die-cutting device.

[0004] To solve the above problems, in a new type of cardboard die-cutting machine with the publication number CN218342301U, the cleaning of paper powder is completed through the collection box and the through holes opened in the support plate. During the process of the die-cutting knife rising after cutting, the pumping device installed by screws on the collection box is used for operation, so that the through holes opened in the support plate suck the dust generated by cutting the cardboard into the connecting pipe and then into the collection box.

[0005] However, since the die-cutting knife has started to rise when cleaning the paper powder, the space where the cardboard and paper powder are located is connected to the outside. If the suction provided by the pumping device is small, it is difficult to suck away all the paper powder well; if the suction provided by the pumping device is large, it is easy to adsorb the die-cut cardboard to the port of the through hole, resulting in the cardboard being wrinkled or even damaged, so it needs to be solved urgently. Content of the Utility Model

[0006] In order to avoid and overcome the technical problems existing in the prior art, the utility model provides a die-cutting air suction device for better cleaning the paper powder generated after die-cutting and other problems.

[0007] To achieve the above purpose, the utility model provides the following technical solutions:

[0008] A die-cutting air suction device includes a die-cutting component that reciprocates up and down to perform die-cutting on cardboard, and a bottom plate located below the die-cutting component for placing the cardboard;

[0010] An air suction device for providing suction to suck away the paper powder in the closed space is connected to the die-cutting cover.

[0011] As a further solution of the present utility model: an air suction port for connecting to the side wall of the air suction device is provided on the die-cutting cover, and the air suction device adopts a vacuum cleaner or an air pump connected with a pipeline.

[0012] As a further solution of the present utility model: a blowing device is further provided on the bottom plate, and the blowing device is used to clean the paper powder on the bottom plate, and the blowing device is connected to the bottom plate through a fixing plate fixed on the upper surface of the bottom plate.

[0013] As a further solution of the present utility model: the die-cutting assembly includes a negative pressure suction cup and a pipeline connected to an external negative pressure device, and the negative pressure suction cup is arranged at the end of the driving shaft of the driving device; the die-cutting cover is connected to the axial surface of the driving shaft of the driving device.

[0014] As a further solution of the present utility model: a die-cutting knife is arranged on the surface of the negative pressure suction cup facing the bottom plate, and when the driving device moves to the lowest position, the die-cutting knife contacts the bottom plate.

[0015] As a further solution of the present utility model: a through hole for passing the pipeline of the negative pressure suction cup is provided on the upper end surface of the die-cutting cover.

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0033] Please refer to Figures 1 - 4, in the embodiment of the present utility model, a die-cutting air suction device includes a die-cutting assembly 1 that reciprocates up and down to perform die-cutting on cardboard, and a bottom plate 2 located below the die-cutting assembly 1 for placing the cardboard. A die-cutting cover 3 is movably connected to the die-cutting assembly 1 and is used to cooperate with the bottom plate 2 to form a closed space during die-cutting, and the cardboard to be die-cut is located within the closed space. An air suction device 4 is connected to the die-cutting cover 3 and is used to provide suction to suck away the paper powder within the closed space; through the closed space formed by the cooperation of the die-cutting cover 3 and the bottom plate 2, the die-cutting knife 13 and the die-cutting area of the cardboard are wrapped within the closed space, effectively avoiding the situation of paper powder scattering everywhere and reducing the difficulty of cleaning the paper powder; after die-cutting is completed, first use the negative pressure suction cup 12 to suck up the cardboard to fix the position of the cardboard, and then use the air suction device 4 connected to the die-cutting cover 3 to suck away the paper powder within the closed space to complete the cleaning of the paper powder; a relatively small suction force can achieve better cleaning of the paper powder within the closed space, achieving the effect of paper powder cleaning without damaging the cardboard.

[0034] An air suction port 31 for connecting to the side wall of the air suction device 4 is provided on the die-cutting cover 3. The air suction device 4 uses a vacuum cleaner or an air pump connected with a pipeline; devices such as an air pump or a vacuum cleaner generate a certain suction force, and suck the paper powder within the closed space out of the closed space through the air suction port 31 to complete the cleaning of the paper powder (it should be noted that how the vacuum cleaner and the air pump generate suction force and how to clean the paper powder again are all prior arts, so they will not be elaborated here).

[0035] The die-cutting assembly includes a negative pressure suction cup 12 and a pipeline connected to an external negative pressure device. The negative pressure suction cup 12 is arranged at the end of the drive shaft of the drive device 11, and a die-cutting knife 13 is arranged on the surface of the negative pressure suction cup 12 facing the bottom plate 2. When the drive device 11 moves to the lowest position, the die-cutting knife 13 contacts the bottom plate 2, and the die-cutting cover 3 is connected to the axial surface of the drive shaft of the drive device, so that the die-cutting cover 3 can also follow the drive shaft to reciprocate in the vertical direction to continuously clean the paper powder. Through the up and down telescoping of the drive shaft of the drive device 11, the negative pressure suction cup 12 and the die-cutting knife 13 are driven to reciprocate in the vertical direction to continuously complete the die-cutting of the cardboard and the negative pressure adsorption of the cardboard. When cleaning the paper powder, the negative pressure suction cup 12 is used to fix the cardboard in the vertical direction to further prevent the cardboard from shifting, wrinkling or being damaged due to the excessive suction force of the air suction device 4, which not only ensures that the cardboard after each die-cutting is on the same axis during transmission, facilitating the subsequent processes, but also can ensure the flatness and integrity of the cardboard.

[0036] A through hole 32 for passing the pipeline of the negative pressure suction cup 12 is provided on the upper end surface of the die-cutting cover 3, and a sealing ring is also provided on the through hole 32 to ensure the sealing of the closed space.

[0037] Working principle: After the cardboard is separated from the raw material by the die-cutting knife 13, turn on the external negative pressure device to make the negative pressure suction cup 12 generate suction force to adsorb the die-cut cardboard to the lower surface of the negative pressure suction cup 12. Then turn on the air suction device 4 to adsorb and clean the paper powder in the closed space. After the cleaning is completed, turn off the air suction device 4. Then start the driving device 11 to move the negative pressure suction cup 12 down to the lowest position, and then turn off the external negative pressure device to place the cardboard on the bottom plate 2 again. After the placement of the cardboard is completed, start the driving device 11 to move the die-cutting cover 3 and the die-cutting assembly upward. Finally, convey the die-cut cardboard products to the next process for collection and sorting through the conveyor belt on the bottom plate 2, and at the same time convey the un-die-cut cardboard raw materials to the lower part of the die-cutting assembly to realize continuous automatic die-cutting of the cardboard.

The blowing device 5 adopts a hair dryer, a blower, etc., and can clean the bottom plate 2 and the un-die-cut cardboard before die-cutting, and clean the bottom plate 2 after die-cutting. It can not only better protect the die-cutting device and avoid situations such as indentation and burst line, but also greatly reduce the amount of paper powder entering the external negative pressure device when adsorbing the cardboard by the negative pressure suction cup 12, and better ensure the normal operation of the external negative pressure device.
