Description

Technical Field

[0001] The utility model belongs to the technical field of die-cutting machines, and in particular relates to a die-cutting mechanism of a printing slotting die-cutting machine. Background Art

[0002] Die-cutting machine is a kind of precision processing equipment, which is widely used in printing, packaging, electronics and other fields. This machine can cut printed products or cardboard into specific shapes by applying a certain pressure according to the shape of the pre-designed die-cutting knife or hardware mold. The working principle of the die-cutting machine involves multiple processes, including die-cutting, creasing, hot stamping and laminating.

[0003] The Chinese patent with application number CN201710741812.5 in the prior art discloses a cutting angle mode conversion mechanism, including two groups of slotting cutter shafts with the same rotation direction located inside the frame, the slotting cutter shafts are arranged front and back, the slotting cutter shafts are respectively connected to the slotting cutter discs and the slotting cutter, a pair of corner cutting knives are respectively fixed on the two groups of slotting cutter discs, the front corner cutting knife and the rear corner cutting knife on the same slotting cutter disc are arranged at intervals in the circumferential direction, the corner cutting knives and slotting knives on different slotting cutter discs have different phases, and the slotting cutter shafts are respectively connected to phase adjustment mechanisms for adjusting the phase of the slotting cutter discs. The present invention can adjust the phases of the front and rear slotting knives and the corner cutting knives without stopping the machine, thereby changing the processing type, and no longer requiring manual adjustment, meeting the needs of different types, and realizing the function of conversion without disassembling and replacing parts.

[0004] The die-cutting mechanism in the die-cutting machine can often only perform one process alone. When die-cutting is required, a die-cutting template is configured, and when creasing is required, a creasing template is configured. Multiple processes cannot be performed simultaneously on one machine, and the die-cutting tool needs to be replaced. The die-cutting tool is generally fixed by bolts, and the installation and disassembly are very cumbersome and time-consuming. For this reason, we propose a die-cutting mechanism for a printing slotting die-cutting machine. Utility Model Content

[0031] See also Figure 1-Figure 4 , the technical solution provided by this embodiment is as follows:

[0032] A die-cutting mechanism of a printing slotting die-cutting machine comprises a base 1, a clamping plate 2, a positioning shaft 3, a mounting shaft 4 and a snap mechanism, wherein: two clamping plates 2 are provided and are fixedly connected to the top of the base 1; the positioning shafts 3 are rotatably connected to the sides of the clamping plates 2, and their adjacent ends are fixedly connected to ear shafts 6; the mounting shaft 4 is located between the two clamping plates 2, one end of which is fixedly connected to a shaft wheel portion 8, which is rotatably connected to one of the ear shafts 6 through the shaft wheel portion 8, and a tool wheel 5 is detachably connected to its circumferential surface, and a clamping block 12 is fixedly connected to the other end; the snap mechanism is provided on the other ear shaft 6, and is used to fix the clamping block 12 to support the stable rotation of the mounting shaft 4.

[0033] In a specific embodiment of the present invention, the tool wheel 5 is a round stick-shaped tool of a commonly used die-cutting machine. The mounting shaft 4 is used to support the rotation of the tool wheel 5. The positioning shaft 3 is mounted on the side of the clamping plate 2 through a bearing. The mounting shaft 4 is mounted between the two positioning shafts 3 to support the stable rotation of the tool wheel 5. In the initial state, the pin 15 passes through the bearings of the block 12 and the ear shaft 6 to limit the movement of the block 12, ensuring that the mounting shaft 4 and the two positioning shafts 3 are located at a concentric position to rotate with the positioning shaft 3. When the tool wheel 5 needs to be replaced, the paddle 16 is toggled to separate the pin 15 from the block 12, and the block 12 can be separated from the ear shaft 6 by toggling upward. At this time, the nut 10 can be turned to separate it from the threaded portion 9. Without the restriction of the nut 10, the tool wheel 5 can be directly pulled out and replaced. Then, the tool wheel 5 can be replaced by reversing the above operation. The installation and disassembly method is simple, and the training requirements are reduced. Compared with the existing threaded fixing structure, the installation and disassembly time is shortened, and a large amount of time and labor costs are saved. Especially in the case of emergency maintenance or frequent equipment movement, the ability to respond quickly is particularly important.

The extension plate 13 is fixedly connected to the side of another ear shaft 6, and a slide groove 14 is provided near the axial hole of the ear shaft 6. The plug pin 15 is slidably connected in the slide groove 14. The end of the plug pin 15 movably penetrates the block 12 and the ear shaft 6 to drive the axial hole. The paddle 16 is fixedly connected to the circumferential surface of the plug pin 15. A spring 17 is sleeved on the circumferential surface of the plug pin 15, and the spring 17 is located between the paddle 16 and the slide groove 14.

[0035] In the specific embodiment of the present utility model, refer to Figure 4 and Figure 5 After the block 12 is inserted into the ear shaft 6, the plug pin 15 passes through the axial holes of the block 12 and the ear shaft 6 to prevent the block 12 from moving, and then fix the position of the block 12, so that the two ends of the installation shaft 4 are restricted by the ear shaft 6, and the two ear shafts 6 correspond to the concentric positions of the positioning shaft 3, thereby supporting the installation shaft 4 to rotate stably. When disassembling, it is only necessary to toggle the paddle 16 to separate the plug pin 15 from the block 12, so that the block 12 can be separated from the ear shaft 6. The installation groove disassembly method is simple and easy to operate, saving time and labor costs. In addition, a spring 17 is installed on the plug pin 15, and the elasticity of the spring 17 is used to push the paddle 16 to prevent the paddle 16 from moving, ensuring that the plug pin 15 will not separate without external force after passing through the axial hole of the block 12. The structure is simple and stable, and the service life is long.

[0036] Specifically, a groove is provided on the circumferential surface of the tool wheel 5, and the tool wheel 5 is slidably sleeved on the surface of the groove.

[0037] In a specific embodiment of the utility model, the inner wall of the tool wheel 5 is provided with a convex strip matching the groove. When installed, the tool wheel 5 is sleeved on the surface of the installation shaft 4 and will rotate with the installation shaft 4 after being fixed in position. The structure is simple and easy to assemble.

[0038] Specifically, the clamping block 12 is provided with a threaded portion 9 near the tool wheel 5 , and a nut 10 is threadedly connected to the threaded portion 9 .

[0039] In a specific embodiment of the present invention, the threaded portion 9 is located between the clamping block 12 and the tool wheel 5 , and tightening the nut 10 can fix the position of the tool wheel 5 , and the fixing method is simplified.

[0040] Specifically, a gasket 11 is sleeved on the surface of the threaded portion 9 , and the gasket 11 is located between the nut 10 and the tool wheel 5 .

[0041] In a specific embodiment of the present invention, the gasket 11 is a metal gasket, which is used to fill the gap between the nut 10 and the tool wheel 5 to ensure that the position of the tool wheel 5 is locked firmly.

[0042] Specifically, a pulley 7 is fixedly connected to the end of one of the positioning shafts 3 .

[0043] In a specific embodiment of the present utility model, the pulley 7 is used to connect to an external driving device to drive the positioning shaft 3 to rotate, and finally drive the tool wheel 5 to rotate to achieve the purpose of die cutting.

[0044] Working principle: when the tool wheel 5 needs to be replaced, the paddle 16 is pushed to separate the pin 15 from the block 12, and the block 12 is pushed upward to separate it from the ear shaft 6. At this time, the nut 10 is turned to separate it from the threaded portion 9. Without the restriction of the nut 10, the tool wheel 5 can be directly pulled out and replaced. Then, the tool wheel 5 can be replaced by reversing the above operation. The installation and disassembly method is simple, and the training requirements are reduced. Compared with the existing threaded fixing structure, the installation and disassembly time is shortened, and a lot of time and labor costs are saved. Especially in the case of emergency repairs or frequent equipment movement, the ability to respond quickly is particularly important.
