[0002] When using a die cutter to cut a material that needs to be printed, the original production technology is to cut in the first step and print in the second step. The two-step cutting and printing method not only complicates the process, but also requires the use of different machines to increase manufacturing costs.

[0003] At present, there are some combined cutting dies that can perform cutting and printing at the same time, including a die body and a stamping mechanism. The stamping mechanism is arranged inside the blade for cutting in the die body, but the stamping surface of the stamping mechanism is farther away from the workpiece to be cut than the cutting surface of the blade, so that some workpieces to be cut need to be thicker in order to be stamped. If the workpiece to be cut is thin, stamping will not be possible. At the same time, there are also some combined cutting dies that can perform cutting and printing at the same time, including a die body and a stamping mechanism. The distance between the stamping surface of the stamping mechanism and the cutting surface of the blade is fixed. There is a situation where the blade has completed cutting but the pressure between the stamping surface and the workpiece to be cut is insufficient, or the pressure between the stamping surface and the workpiece to be cut has reached the stamping limit, but the blade has not completely cut the workpiece to be cut.

[0004] Therefore, there is an urgent need for a cutting mechanism that can solve the problem of cutting and stamping pieces of various thicknesses at the same time, and achieve the goal of simple operation and high cutting and stamping efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a cutting mechanism which can solve the problem of cutting and stamping pieces of various thicknesses at the same time, and achieve the goals of simple operation and high cutting and stamping efficiency.

[0014] The cutting die is arranged on the bottom surface of the mounting member, the cutting edge is protruding downward, a first mounting hole is arranged on the cutting die, and the printing component is connected to the cutting die and passed through the first mounting hole.

It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the drawings only show portions relevant to the present invention, not all of them.

Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0034] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0035] like Figure 1 As shown, this embodiment provides a cutting die mechanism including a cutting die assembly 1 and a printing assembly 2. The cutting die assembly 1 includes a protruding blade 121, which is used to cut the workpiece to be cut. The printing assembly 2 is connected to the cutting die assembly 1, and the printing assembly 2 is provided with a printing surface 212 that can contact the workpiece to be cut. The printing assembly 2 has elasticity so that the printing assembly 2 can achieve elastic compensation when it abuts against the workpiece to be cut. Since the printing assembly 2 is provided with a printing surface 212 that can contact the workpiece to be cut, and the cutting die assembly 1 is provided with a blade 121 for cutting the workpiece to be cut, the cutting die mechanism can print the workpiece to be cut while cutting the workpiece to be cut. Since the printing component 2 is elastic and realizes elastic compensation when it abuts against the workpiece to be cut, the printing component 2 can have room for movement within its elastic limit, so that it can adapt to workpieces to be cut of various thicknesses, avoiding the fixed distance between the printing surface 212 and the cutting surface of the blade 121, thereby avoiding the situation where the blade 121 has completed cutting but the pressure between the imprinting surface and the workpiece to be cut is insufficient and cannot be completely printed. At the same time, it can also avoid the situation where the printing surface 212 and the workpiece to be cut have reached the imprinting limit but the blade 121 has not completely cut the workpiece to be cut.

[0036] Optionally, there is a printed pattern on the printed surface 212, and the printed pattern can be set as needed.

[0037] Optionally, in this embodiment, the blade 121 is a single-edged blade, which is sharpened on one side. The blade 121 is finely ground and very sharp, and can easily cut a variety of materials. In other embodiments, the blade 121 can be a double-edged blade, as long as it can effectively cut the workpiece.

[0038] Optionally, the height of the blade 121 can be set to be 1-6 mm higher than the thickness of the material to be cut. A blade 121 slightly longer than the thickness of the material to be cut can reduce repeated strokes during the cutting process, thereby improving cutting efficiency. A longer blade 121 can remove more material in one go, reducing the number of cuts and saving time. Furthermore, during complex machining processes, a blade 121 slightly longer than the thickness of the material to be cut can better adapt to the shape and contour of the material to be cut, reducing interference between the cutting mechanism and the material to be cut, and ensuring smooth machining. For example, the height of the blade 121 can be set to be 2 mm, 3 mm, or 4 mm higher than the thickness of the material to be cut.

[0039] Specifically, if Figure 1-2 As shown, in this embodiment, the printing assembly 2 includes an elastic member 22 and a stamp body 21. Optionally, one end of the elastic member 22 abuts or connects with the die assembly 1, and the other end of the elastic member 22 abuts or connects with the stamp body 21. In this embodiment, as shown in FIG. Figure 1-2 As shown, one end of the elastic member 22 is in contact with the cutting die assembly 1, and the other end of the elastic member 22 is connected to the stamp body 21. When the workpiece to be cut is cut by the blade 121, the stamp body 21 compresses the elastic member 22 after receiving the force of the workpiece to be cut, so that the stamp body 21 can be reasonably moved according to the thickness of the workpiece to be cut, and the distance between the printing surface 212 and the cutting surface of the blade 121 can be changed. After the workpiece to be cut is cut, due to the characteristics of the elastic member 22, the stamp body 21 can be pushed back to its original position without affecting the next cutting and printing. In addition, the separate setting of the elastic member 22 and the stamp body 21 also facilitates the inspection and maintenance of the printing assembly 2. When one of them is damaged, the elastic member 22 or the stamp body 21 can be replaced in a targeted manner without completely replacing the entire printing assembly 2.

[0040] In this embodiment, if Figure 1-2 As shown, the elastic member 22 is made of an elastic material with good elasticity, capable of returning to its original shape after being subjected to force. Furthermore, the elastic material has a large contact area with the seal body 21, and the interaction force is relatively dispersed across the area without damaging the seal body 21. This allows the reciprocating motion of the printing assembly 2 to accumulate pressure and provide power. In other embodiments, the elastic member 22 may also be a spring, which can also provide support for the motion of the seal body 21.

[0041] Optionally, in this embodiment, the elastic member 22 is made of elastic silicone. Elastic silicone has excellent softness and elasticity, can adapt to various changes in shape and size, quickly return to its original shape, and is not prone to permanent deformation. This property improves the durability of the product and also makes elastic silicone more cost-effective. In other embodiments, the elastic material used for the elastic member 22 can be rubber, elastic plastic, etc., as long as the material is elastic.

[0042] Optionally, the elastic member 22 may be fixedly connected to the seal body 21 by bonding, so as to simplify the structure and reduce costs.

[0043] Optionally, in this embodiment, the seal body 21 may be made of steel. Steel's high hardness makes it easier to print on workpieces. Steel's ease of cutting also makes it easier to make seals from. Furthermore, steel is relatively inexpensive, offering a high cost-effectiveness and suitability for large-scale production. In other embodiments, the seal body 21 may be made of plastic, stone, or other materials, as long as they are sufficiently hard and can effectively print on workpieces.

[0044] like Figure 1-3 As shown, in this embodiment, when the elastic member 22 is not squeezed, the printed surface 212 and the cutting surface of the blade 121 in contact with the workpiece are coplanar, allowing the blade 121 to print on the workpiece when it contacts it, thereby enabling the cutting mechanism to simultaneously print on workpieces of various sizes. In other embodiments, when the elastic member 22 is not squeezed, the printed surface 212 can be positioned closer to the workpiece relative to the cutting surface, as long as simultaneous printing can be achieved for workpieces of various sizes.

[0045] Specifically, if Figure 1 As shown, in this embodiment, the cutting die assembly 1 includes a mounting member 11 and a cutting die 12. The cutting die 12 is arranged on the bottom surface of the mounting member 11, and the blade 121 is protruding downward. The printing assembly 2 is passed through the mounting member 11 and connected to the mounting member 11, so that the printing assembly 2 can slide in the mounting member 11, thereby realizing printing on the piece to be cut.

[0046] More specifically, if Figure 1 As shown, in this embodiment, a first mounting hole 122 is further provided on the cutting die 12, and the printing component 2 is inserted into the first mounting hole 122. The above arrangement enables the portion of the printing component 2 inserted into the first mounting hole 122 to reciprocate within the first mounting hole 122, and guides the sliding direction of the portion of the printing component 2 inserted into the first mounting hole 122. At the same time, through the arrangement of the first mounting hole 122 and the nested arrangement of the cutting die 12 and the printing component 2, the structure of the cutting mechanism is compact, and the printing position is not restricted by the position of the blade 121. When cutting the surface to be cut, the printing component 2 can slide flexibly within the first mounting hole 122 according to the thickness of the workpiece to be cut to ensure efficient completion of both cutting and printing.

[0047] In other embodiments, the printing assembly 2 can be directly connected to the cutting die 12. Optionally, the cutting die 12 is also provided with a first mounting hole 122, and the printing assembly 2 is inserted into the first mounting hole 122 to provide a guide for the compression of the printing assembly 2.

[0048] Optionally, the printing component 2 can be fixed to the cutting die 12 by snapping, bonding or fasteners and other connecting parts, so that the printing component 2 can move with the cutting die component 1 and contact the workpiece to be cut, thereby achieving cutting and printing on the workpiece to be cut at the same time, ensuring the efficient completion of both cutting and printing, and enabling the cutting mechanism to adapt to the problem of cutting and stamping workpieces of various thicknesses at the same time.

[0049] Alternatively, as Figure 1 As shown, in this embodiment, the mounting member 11 and the cutting die 12 form a receiving groove 111, and a portion of the printing assembly 2 is slidably disposed in the receiving groove 111. The receiving groove 111 is connected to the first mounting hole 122, so that the receiving groove 111 and the first mounting hole 122 are combined to form a sliding space, so that the seal body 21 can slide back and forth in the sliding space. At the same time, the sliding space can also guide the sliding of the seal body 21. When cutting the workpiece to be cut, the seal body 21 moves in the sliding space according to the cutting situation, so that the cutting mechanism will not cause the blade 121 to have completed the cutting but the pressure between the imprinting surface and the workpiece to be cut is insufficient, or the pressure between the imprinting surface and the workpiece to be cut has reached the imprinting limit, but the blade 121 has not yet completely cut the workpiece to be cut.

[0050] In other embodiments, the accommodating groove 111 may be surrounded by only the mounting member 11, and part of the printing component 2 may be slidably disposed in the accommodating groove 111. As long as the printing component 2 can slide during the cutting process, it is sufficient to avoid the situation where the print is not printed after cutting, or the printing limit is reached between the printing surface and the workpiece to be cut, but the blade 121 has not completely cut the workpiece to be cut.

[0051] More specifically, in this embodiment, if Figure 1-3 As shown, the cross-sectional area of ​​the receiving groove 111 is larger than that of the first mounting hole 122. The portion of the stamp body 21 located within the receiving groove 111 is provided with at least one protrusion 211, which is capable of abutting against the inner wall of the receiving groove 111 on one side near the cutting die 12. This arrangement prevents the stamp body 21 from slipping out of the cutting die assembly 1, thereby preventing the stamp body 21 from slipping out and affecting the operation of the cutting mechanism, and preventing the stamp body 21 from damaging the cutting mechanism and causing irreversible damage.

[0052] Specifically, if Figure 1-2 As shown, in this embodiment, the seal body 21 is provided with a sleeve 3 on the outer sleeve, and the sleeve 3 is fixedly arranged in the cutting die assembly 1. One end of the sleeve 3 is passed through the first mounting hole 122. The setting of the sleeve 3 isolates the cutting die assembly 1 and the seal body 21, avoiding relative force between the cutting die assembly 1 and the seal body 21, and thus preventing the cutting die assembly 1 and the seal body 21 from being damaged.

[0053] More specifically, if Figure 1-3 As shown, the outer diameter of the portion of the sleeve 3 that passes through the first mounting hole 122 is smaller than the outer diameter of the portion of the sleeve 3 that passes through the accommodating groove 111, and the outer diameter of the portion of the sleeve 3 that passes through the accommodating groove 111 is larger than the inner diameter of the first mounting hole 122, so that the sleeve 3 can abut against the cutting die 12 to ensure that the sleeve 3 will not slip out of the cutting mechanism, avoid damaging the cutting die or other parts, and thus cause the cutting mechanism to be unable to use normally.

[0054] Specifically, if Figure 1-3 As shown, in this embodiment, the sleeve 3 is provided with a notch at a position corresponding to the protrusion 211 to ensure that the seal body 21 can slide normally during the cutting process, thereby avoiding the sleeve 3 not being able to slide normally due to the absence of an avoidance notch, thereby affecting the normal cutting and printing process.

[0055] Optionally, the sleeve 3 and the mounting member 11 are fixed by an interference fit to simplify the fixing structure and reduce costs. Specifically, in this embodiment, the portion of the sleeve 3 inserted into the receiving groove 111 and the mounting groove 111 have an interference fit, so that the portion of the sleeve 3 inserted into the receiving groove 111 is fixed and cannot move, thereby securing the sleeve 3 within the cutting die assembly 1. This not only simplifies the fixing structure and reduces costs, but also prevents the sleeve 3 from slipping out of the cutting die assembly 1, thereby preventing the parts that make up the cutting mechanism from being damaged.

[0056] Optionally, in this embodiment, the sleeve 3 is made of plastic. Since plastic has strong wear resistance and high impact resistance, using plastic to make the sleeve 3 can effectively isolate the impact of the cutting die assembly 1 and the seal body 21, and can also isolate the cutting die assembly 1 and the seal body 21. In other embodiments, the material of the sleeve 3 can be silicone or non-woven fabric, etc., as long as it can isolate the cutting die assembly 1 and the seal body 21 and absorb the forces acting between the cutting die assembly 1 and the seal body 21.

[0057] Specifically, the die-cutting assembly 1 also includes a stopper that extends into the end of the accommodating groove 111 facing away from the printing surface 212, for contact with the printing assembly 2. The stopper limits the range of motion of the stamp body 21 along its sliding direction. If the range of motion is too large, when the blade 121 has penetrated the workpiece to its maximum depth, the stamp body 21 has not yet contacted the elastic member 22, or the printing assembly 2 has not yet contacted the mounting member 11. The stamp body 21 loses its force toward the workpiece, preventing normal printing.

[0058] Optionally, in this embodiment, the limiting member is a jackscrew, and the limiting member is threadedly connected to the die-cutting assembly 1. Since the limiting member is threadedly connected to the die-cutting assembly 1, the range of motion of the seal body 21 along its sliding direction can be adjusted, and it can be adapted to various models of printing assemblies 2, while also limiting the position of the seal body 21. In other embodiments, the limiting member can also be a limiting block, as long as it is a component that can limit the range of motion of the seal body 21 along its sliding direction, and no further details will be given.

[0059] In this embodiment, if Figure 1 As shown, the cutting die 12 is provided with six groups of blades 121 for cutting the objects to be cut, allowing multiple objects to be cut simultaneously, thereby improving the cutting efficiency of the cutting mechanism. In other embodiments, the blades 121 can be provided in any group as long as the cutting function can be achieved. For example, the cutting die 12 can be provided with three, four, or five groups of blades 121.

[0060] This embodiment also discloses a cutting device including a pressurizing mechanism and a cutting mechanism. The pressurizing mechanism is connected to or abuts against the cutting mechanism. The pressurizing mechanism is used to apply pressure to the cutting mechanism to assist the cutting mechanism in completing the cutting work, so that the cutting mechanism can perform printing while cutting.

[0061] It should be noted here that the pressure mechanism for the cutting equipment is an existing structure, and setting a pressure mechanism in the cutting equipment is a conventional setting in this field. In this embodiment, any pressure mechanism in the existing technology can be used to apply pressure to the cutting mechanism. As long as the auxiliary cutting mechanism can complete the cutting work, the cutting mechanism can realize the printing work while cutting, and no further detailed introduction will be given.

[0062] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
