[0028] Reference Figures 1 to 3 The die-cutting device for easily replacing cutting tools in this embodiment includes components such as a base 100, a cutting tool module 200 and a driving member 300. The cutting tool module 200 and the driving member 300 are both connected to the base 100, and the base 100 is part of the frame. When the die-cutting device is installed somewhere, in addition to the above-mentioned cutting tool module 200, there may be some other modules next to it. The distance between the components of each module may be relatively small, so that the operating space is small when the cutting tool module 200 needs to be replaced, which brings inconvenience to the replacement. Therefore, in this embodiment, when the cutting tool module 200 needs to be replaced, the cutting tool module 200 can be driven by the driving member 300 to move horizontally so as to extend out of the base 100. When the cutting tool module 200 is extended, there are no other components around it, the operating space will become larger, the operation will be more convenient, the replacement speed will also be faster, and to a certain extent, the impact of replacing the cutting tool module 200 on production efficiency can be reduced.

[0029] Specifically, refer to Figures 2 to 5, in some embodiments, also comprise mobile member 400, gear train 500 and driven rack 620.Gear train 500 comprises the first gear 520, and the first gear 520 is the gear that is positioned at the output end among the gear train 500, and driven rack 620 is fixed on the mobile member 400, and driven rack 620 can mesh with the first gear 520.Driver 300 can be connected with the gear that is positioned at the input end among the gear train 500, drives this gear to rotate by driver 300.For example, can select for use steering gear as driver 300, the steering gear arm of steering gear is connected with the gear of the input end among the gear train 500, uses steering gear to can reduce device weight.Perhaps, also can driver 300 directly be connected with the first gear 520, also can use parts such as linear motor, cylinder or motor screw, driver 300 is indirectly connected with the gear of the input end among the gear train 500, and linear motion is converted into the rotation of gear.

[0030] Reference Figures 4 and 5 In some embodiments, the gear set 500 includes a second gear 510, a first gear 520, and a third gear 530. The second gear 510 is meshed with the first gear 520, and the third gear 530 is coaxial with the second gear 510, so that the two can rotate synchronously. The third gear 530 is driven to rotate by the driving member 300, and the second gear 510 is driven to rotate synchronously, thereby driving the first gear 520 to rotate. The first gear 520 is the output end gear of the gear set 500, and the first gear 520 is meshed with the driven rack 620. The diameter of the second gear 510 is larger than the size of the first gear 520. In this way, the angle of rotation of the first gear 520 can be larger, and accordingly, the distance moved by the driven rack 620 is also greater. By providing the acceleration gear set 500, the moving stroke of the movable member 400 can be increased. In this way, the tool module 200 can be extended to a farther position with the movable member 400, making it easier for the operator to operate. In addition, other gears may be added between the second gear 510 and the first gear 520 as intermediate gears as needed, or the third gear 530 may be removed and the driving member 300 may be directly connected to the second gear 510 .

[0031] Reference Figures 3 and 4In some embodiments, an active rack 610 is further provided, and the driving member 300 is selected from components such as a linear motor or a cylinder. The active rack 610 is driven to move by the driving member 300, and the active rack 610 is engaged with the third gear 530. In addition, a first slider 710 and a first slide rail 720 are further provided, and the first slider 710 is connected to the active rack 610, and the first slide rail 720 is connected to the base 100. When the movable member 400 and the tool module 200 move, the first slider 710 will slide along the first slide rail 720 to guide, so that the motion stroke of the active rack 610 is more stable. In addition, a second slider 730 and a second slide rail 740 are further provided, and the second slider 730 is connected to the base 100, and the second slide rail 740 is connected to the movable member 400. When the movable member 400 moves, the second slider 730 will slide along the second slide rail 740 to guide.

[0032] Compared with directly using a cylinder to push the moving part 400, by setting up a gear set 500, the stroke of the cylinder can be reduced, and a shorter piston rod can be selected to meet the requirements, thereby reducing the size of the cylinder, making the structure of the entire device more compact, and reducing its space requirements during installation.

[0033] Reference Figure 1 and Figure 2 In some embodiments, the cutting tool module 200 is connected to the top of the moving member 400, the moving member 400 is located above the base 100, and the driving member 300 and the gear assembly 500 are located between the cutting tool module 200 and the base 100. In this way, when the cutting tool module 200 is in the initial state and has not been extended, the cutting tool module 200, the driving member 300, the gear assembly 500, and the base 100 are arranged in a compact structure in the horizontal direction, occupying less space.

[0034] Specifically, refer to Figures 2 to 4 In some embodiments, the moving member 400 is further provided with an avoidance groove 410. Specifically, a piece can be dug out at the end of the moving member 400 to form the avoidance groove 410. When the tool module 200 is in the initial state and has not been extended, the driving member 300 and the gear set 500 are located in the avoidance groove 410. In this way, there is no need to increase the gap between the moving member 400 and the base 100 to accommodate these components, and the gap between the moving member 400 and the base 100 can be made smaller. In the vertical direction, the size of the entire device is smaller, the structural distribution is more compact, and the space occupied is smaller.

[0035] In some embodiments, both sides of the moving member 400 are provided with abutting members 800, and both sides of the base 100 are provided with guide members 110. The guide members 110 define a guide channel 111. When the moving member 400 moves, the abutting members 800 will slide in the guide channel 111, and the movement process of the moving member 400 is guided by the guide channel 111, so that its movement process is more stable. In addition, the top of the abutting members 800 can abut against the inner side wall of the guide member 110. When the moving member 400 and the tool module 200 extend outside the base 100, the part of the moving member 400 that extends out is suspended. Since the top of the abutting members 800 abuts against the inner side wall of the guide member 110, the part of the moving member 400 that does not extend out can be pressed downward to prevent the extended part from falling due to being insufficient to bear the weight of the tool module 200, which can make the device structure more stable and firm.

[0036] In certain embodiments, also be provided with the first connecting member 910 and the second connecting member 920.One end of the first connecting member 910 is rotationally connected with the second connecting member 920, and the other end is rotationally connected with moving member 400.One end of the second connecting member 920 is rotationally connected with the first connecting member 910, and the other end is rotationally connected with the 3rd connecting member 930, and the 3rd connecting member 930 is fixedly connected with base 100 (the two are connected by intermediate member not shown in the figure).When moving member 400 moves, the first connecting member 910 and the second connecting member 920 can rotate, and its position form changes.Concrete, when moving member 400 extends to outside base 100, the first connecting member 910 and the second connecting member 920 are collinear, and the height of the connecting position of the second connecting member 920 and the 3rd connecting member 930 is greater than the height of the connecting position of the first connecting member 910 and moving member 400. In this way, the movable member 400 can be pulled upward by the first connecting member 910 and the second connecting member 920 to prevent it from falling due to the lack of support from the base 100 at the bottom after being extended, thereby making the device structure more stable and firm.

[0037] Alternatively, in some embodiments, an elastic member may be used to connect the movable member 400 to the frame, with the height of the connection point between the elastic member and the frame being greater than the connection point between the elastic member and the movable member 400. When the movable member 400 is extended, the elastic member is stretched, and the elastic force of the elastic member pulls the movable member 400 upward to prevent it from falling due to the lack of support from the base 100 at the bottom after extension.

[0038] In some embodiments, a first limiter driver 1100 is connected to the side of the base 100. The first limiter driver 1100 can be a cylinder. The telescopic end of the cylinder is fixedly connected to the first limiter 1000. The first limiter driver 1100 can drive the first limiter 1000 to extend or retract toward the movable member 400. A second limiter 420 is provided on the side wall of the movable member 400. When the movable member 400 is reset, the first limiter driver 1100 drives the first limiter 1000 to extend. The first limiter 1000 and the second limiter 420 cooperate to limit the movable member 400. When the first limiter driver 1100 drives the first limiter 1000 to retract, the limiting relationship between the first limiter 1000 and the second limiter 420 is released, and the movable member 400 can be extended again. In this embodiment, the first limiting member 1000 is a protrusion, and the second limiting member 420 is a groove. Of course, they can also be swapped or changed in shape.

[0039] In some embodiments, the cutter module 200 includes a first cutting rod 210 and a second cutting rod 220, which rotate in opposite directions and form a feed gap between them for material to pass through. Both the first cutting rod 210 and the second cutting rod 220 have raised blades on their surfaces that can cut material within the feed gap. When the cutter module 200 needs to be replaced, the first and second cutting rods 210, 220 are the primary replacement components.

[0040] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the embodiments described above. Various modifications may be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof may be combined with one another unless there is a conflict.
