Description

Technical Field

[0001] This utility model relates to the field of die-cutting technology, specifically to a die-cutting device. Background Art

[0002] Die-cutting blades, also called die-cutting knives or creasing knives, are sheet materials made of steel with a cutting edge at the tip, used to create die-cutting slabs. The performance requirements for die-cutting blades include uniform steel quality, appropriate combination of blade body and blade edge hardness, accurate specifications, and hardened blade edges. High-quality die-cutting blades typically have a blade edge hardness significantly higher than the blade body hardness, which facilitates forming and provides a longer die-cutting life.

[0003] In the prior art, Chinese Utility Model Publication No. CN217703727U discloses a circular knife die-cutting device for irregular shapes, including a machine body, a rolling roller disposed within the machine body, a die-cutting roller disposed below the rolling roller, a button disposed on the machine body, and a mounting plate disposed below the die-cutting roller, with a mounting post disposed on the mounting plate. This circular knife die-cutting device, belonging to the field of die-cutting machines, utilizes an upper buffer plate and buffer springs to cushion falling cardboard, reducing damage to the edges and corners. The position of the upper buffer plate is easily adjustable. The front and rear fixing rods facilitate pulling the rear fixing rod, compressing the cardboard and ensuring the front and rear edges of the cardboard stack are aligned, preventing scattering during subsequent removal and making it more convenient to use.

[0004] The die-cutting roller in the above technical solution is a traditional die-cutting roller. The blades on the die-cutting roller are fixedly installed on the surface of the roller, and the distance between adjacent blades cannot be changed. This results in the need to constantly change the die-cutting roller for adjustment, which is not only inconvenient to disassemble and assemble, but also has a high manufacturing cost.

[0005] The purpose of this utility model is to provide a die-cutting knife device. By adjusting the included angle between the connecting support rods through the distance adjustment component, the distance between the mounting base and the rotating drum is adjusted, increasing the radius of the circle formed by the long strip blades, so that the distance between the two sets of long strip blades changes, meeting the needs of different distances between the blades. At the same time, the ring blade is held in place on the outside of the mounting base under the support of the mounting base, and the distance between the ring blades can be adjusted, avoiding frequent replacement of the cutter roller, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a die-cutting device, comprising:

[0007] Long blades and ring blades;

[0008] It also includes a mounting base for mounting the long blade and the ring blade, and a mounting cylinder assembly for mounting and supporting the mounting base;

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] This utility model provides, for example Figures 1 to 7 The die-cutting device shown includes:

[0033] Long blade 1 and ring blade 2;

[0034] It also includes a mounting base 3 for mounting the long blade 1 and the ring blade 2, and a mounting cylinder assembly 4 for mounting and supporting the mounting base 3;

[0035] The long blade 1 is fixedly installed in the inner cavity of the mounting base 3 by the first mounting screw 5, and the ring blade 2 is snapped onto the outer side of the mounting base 3;

[0036] The mounting cylinder assembly 4 includes a rotating cylinder 41. Multiple sets of symmetrical through slots 6 are opened on the outer side of the rotating cylinder 41. A movable block 7 is movably arranged in the inner cavity of the rotating cylinder 41. A first fixed seat 8 is fixed on the surface of the movable block 7 in the through slot 6. A second fixed seat 9 is fixed on the opposite side of the mounting seat 3. A connecting support rod 10 is rotatably connected between the first fixed seat 8 and the second fixed seat 9 through a movable shaft. A distance adjustment assembly 11 for adjusting the movable block 7 to face each other is provided in the inner cavity of the rotating cylinder 41.

[0037] The distance adjustment component 11 drives two sets of movable blocks 7 to move towards each other inside the rotating drum 41. The mounting base 3 is supported by the connecting support rod 10. The distance between the mounting base 3 and the rotating drum 41 is adjusted, which makes it easy to change the radius of the cylinder formed by multiple sets of mounting bases 3. This changes the distance between the long strip blades 1 on the outer side of the mounting base 3, avoiding frequent replacement of the die-cutting roller. At the same time, the ring blade 2 can be directly adjusted on the mounting base 3 and then locked in place, which makes it easy to adjust the blade distance.

[0038] Among them, such as Figure 4 As shown:

[0039] The distance adjustment assembly 11 includes a drive motor 111 installed at one end of the rotating drum 41. The output shaft of the drive motor 111 passes through the inner cavity of the rotating drum 41 and is fixed with an adjusting screw 112. The adjusting screw 112 is rotatably connected to the rotating drum 41 through a bearing. The movable block 7 is threadedly connected to the outside of the adjusting screw 112. The drive motor 111 drives the adjusting screw 112 to rotate, and then the adjusting screw 112 drives two sets of movable blocks 7 to move towards each other inside the rotating drum 41, thereby adjusting the angle of the connecting support rod 10 and realizing the distance adjustment between the mounting base 3 and the rotating drum 41.

[0040] Furthermore, such as Figure 1 and Figure 5 As shown:

[0041] A mounting plate 12 is fixed to the back of the long blade 1. Multiple countersunk holes are formed on the outer side of the mounting plate 12. The first mounting screw 5 is located in the countersunk hole and is threadedly connected to the mounting base 3. The mounting plate 12 facilitates the placement of the long blade 1 inside the mounting base 3 and fixation by the first mounting screw 5, thereby improving the stability of the long blade 1.

[0042] Preferred, such as Figure 1-3 and Figure 6 As shown:

[0043] The mounting cylinder assembly 4 also includes connecting seats 42 located at both ends of the rotating cylinder 41. The outer side of the connecting seat 42 is provided with countersunk holes, and a second mounting screw 13 is provided in the countersunk holes. The second mounting screw 13 passes through the connecting seat 42 and is threadedly connected to the end of the rotating cylinder 41. The connecting seat 42 can be installed at both ends of the rotating cylinder 41 by means of the second mounting screw 13, which facilitates the assembly and disassembly of the rotating cylinder 41.

[0044] It is worth noting that, such as Figure 3 and Figure 4 As shown:

[0045] The movable block 7 has three sets of through holes, and a limit rod 14 is slidably installed in the through holes. The two ends of the limit rod 14 are fixed to the inner wall of the rotating cylinder 41. The three sets of limit rods 14 facilitate the limiting of the movable block 7, preventing the movable block 7 from rotating with the rotation of the adjusting screw 112, which would cause the first fixed seat 8 to get stuck in the through groove 6, thus ensuring that the first fixed seat 8 and the connecting support rod 10 move smoothly.

[0046] In a further preferred embodiment, such as Figure 6 As shown:

[0047] A block 15 is fixed on one side of the connecting seat 42 facing each other. Square grooves 19 are opened at both ends of the rotating drum 41. The block 15 is snapped into the square groove 19. By setting the block 15 on the connecting seat 42 and using the block 15 to snap into the square groove 19, the stability of the connection between the connecting seat 42 and the rotating drum 41 is improved, and the second mounting screw 13 is prevented from breaking due to large torque when the connecting seat 42 drives the rotating drum 41 to rotate.

[0048] In addition, if Figure 1 , Figure 2 and Figure 5 As shown:

[0049] Multiple sets of slots 16 are provided on the outer side of the mounting base 3 along the axial direction. The ring cutter 2 is engaged in the slots 16. The slots 16 facilitate the engagement of the ring cutter 2 and increase the stability of the connection between the ring cutter 2 and the mounting base 3.

[0050] In this embodiment, as Figure 7 As shown:

[0051] The adjusting screw 112 includes multiple bidirectional screws 1121, which are connected end to end in a straight line. By limiting the structure of the adjusting screw 112, the bidirectional screws 1121 drive the two sets of movable blocks 7, so that the two sets of movable blocks 7 can move and adjust in opposite directions.

[0052] In addition, if Figure 5 As shown:

[0053] A limiting block 17 is fixed on the inner side of the mounting base 3. The limiting block 17 is engaged in the inner cavity of the through groove 6. By setting the limiting block 17 on the inner side of the limiting base, the mounting base 3 and the rotating cylinder 41 are stably connected when they are in contact, thus preventing the mounting base 3 from shaking.

[0054] In this embodiment, as Figure 2 and Figure 5 As shown:

[0055] The distance between adjacent slots 16 is the same. A set of positioning blocks 18 is fixed on the outside of the ring cutter 2. The positioning blocks 18 are located in the inner cavity of a set of mounting bases 3. By limiting the distance between the slots 16, it is convenient to adjust the distance between the ring cutters 2 at equal intervals. At the same time, the positioning blocks 18 on the ring cutter 2 prevent the ring cutter 2 from rotating on the mounting base 3.

[0056] In practical use, the long blade 1 is placed inside the mounting base 3 via the mounting plate 12. Then, the mounting plate 12 is fixed inside the mounting base 3 by the first mounting screw 5. At the same time, the drive motor 111 is started, which drives the adjusting screw 112 to rotate. The bidirectional screw 1121 drives the two sets of movable blocks 7 to move towards each other under the restriction of the limit rod 14, adjusting the angle of the connecting support rod 10, so that the distance between the mounting base 3 and the rotating drum 41 changes. This allows the radius of the circle formed by the long blades 1 installed on the multiple sets of mounting base 3 to change, thereby changing the blade spacing between the long blades 1 installed on the two sets of mounting base 3. This makes it easy to adjust the distance between the long blades 1. At the same time, multiple sets of ring blades 2 can be set on the outside of the mounting base 3, penetrating the mounting base 3 away from the rotating drum 41, so that the ring blades 2 are engaged in the slots 16 on the mounting base 3, ensuring the stability of the ring blades 2. By adjusting the ring blades 2 in different slots 16, it is easy to adjust the blade spacing of adjacent ring blades 2.

[0057] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
