For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] See also Figure 1-Figure 7 As shown in the figure, a quick-change tool head device for die-cutting and engraving equipment is characterized in that it includes a tool body 1, a tool head 2 and an elastic fastener 2-2. The tool head 2 is detachably connected to one end of the tool body 1 through the elastic fastener 2-2. Through the setting of the elastic fastener, the tool head 2 can be detachably installed on the tool body 1. When replacing a different tool head 2, it is only necessary to directly replace the tool head 2 without replacing the entire tool. The structure is simple, the disassembly and assembly are quick and convenient, and the cost is low.

[0026] In one embodiment, the elastic fastener 2-2 includes a convex buckle 2-2a connected to the cutter head 2, and the convex buckle 2-2a is provided with at least one shrinkage groove 2-2b; through the setting of the shrinkage groove 2-2b, the convex buckle 2-2a can shrink inward when being squeezed inward, so that the convex buckle 2-2a can pass through the set hole 1-1a to remove or install the cutter head 2.

[0027] In one embodiment, the convex buckle 2-2a is provided with a limiting boss 2-2c protruding outward;

[0028] The rotating shaft 1-1 is provided with a set hole 1-1a connected to the elastic fastener 2-2 and an inner step hole 1-1d for facilitating the positioning of the elastic fastener 2-2;

[0029] When the cutter head 2 is installed by snap-fitting, the limiting boss 2-2c on the head of the convex buckle 2-2a is snapped into the inner step hole 1-1d at the upper end of the sleeve hole 1-1a to complete the installation of the cutter head 2. The cutter head 2 is fixedly mounted on the rotating shaft 1-1 by the limiting boss 2-2c and the inner step hole 1-1d.

[0030] In one embodiment, the blade body 1 further comprises a sleeve 1-2, a bearing 1-3, a rotating shaft 1-1 mounted in the sleeve 1-2 via the bearing 1-3, and an end cover 1-4 is mounted on the upper portion of the rotating shaft 1-1.

[0031] In one embodiment, the lower part of the rotating shaft 1-1 is provided with an outer cylinder connected to the cutter head 2, and the outer cylinder is provided with at least one plane 1-1c; the cutter head 2 is provided with an upper cavity 2-1c, and the upper cavity 2-1c is also provided with at least one plane 1-1c adapted to the outer cylinder;

[0032] The plane 1-1c on the outer cylinder and the upper concave cavity 2-1c can be replaced by a polygon, such as a rectangle, a hexagon or a rhombus;

[0033] The arrangement of the plane 1-1c limits the position of the cutter head 2 installed on the rotating shaft 1-1, and can drive the cutter head 2 to rotate when the rotating shaft 1-1 rotates.

[0034] In one embodiment, the blade body 1 also includes a push rod 1-6 that passes through the rotating shaft 1-1 and the end cover 1-4 and is movably arranged in the rotating shaft 1-1; through the arrangement of the push rod 1-6, when the blade head 2 is disassembled, the push rod 1-6 can be pressed downward, and the push rod 1-6 forms a downward thrust on the convex buckle 2-2a, and the convex buckle 2-2a shrinks inward after receiving the downward thrust, and after shrinking, it moves downward along the fitting hole 1-1a until the blade head 2 is disengaged from the rotating shaft 1-1, thereby completing the disassembly of the blade head 2.

[0035] In one embodiment, it also includes a compression spring 1-5 arranged between the rotating shaft 1-1 and the push rod 1-6 for driving the push rod 1-6 to reset. The compression spring 1-5 is limited by a step, and the compression spring 1-5 is arranged to drive the push rod 1-6 to reset.

[0036] In one embodiment, the tool head 2 is any one of a pointed needle scribing tool head, a dotted line roller creasing tool head, a single line roller creasing tool head, a double line roller creasing tool head and a wavy line roller creasing tool head 7. The corresponding tool head can be selected for installation and use according to usage requirements.

[0037] When the tool of the utility model is used as a passive tool, the tool body 1 moves with the device, and the tool head 2 does not need to rotate. The tool body 1 can be integral, and there is no need to set a rotating shaft. The tool head 2 can be directly installed on the tool body 1 through an elastic fastener 2-2 or other parts that can be quickly replaced.

[0038] When used as an active knife, the knife body 1 also includes a sleeve 1-2, a bearing 1-3, a rotating shaft 1-1 installed in the sleeve 1-2 through the bearing 1-3, an end cover 1-4 is installed on the upper part of the rotating shaft 1-1, and the knife head 2 is installed on the rotating shaft through an elastic fastener 2-2 or other parts that can be quickly replaced; during use, the driving device in the equipment can drive the rotating shaft 1-1 to rotate, so that the rotating shaft 1-1 can drive the knife head 2 to rotate.

[0039] During installation, firstly, the upper concave cavity 1-1c on the cutter head 2 is aligned with the position of the outer cylinder of the rotating shaft 1-1, and then the cutter head 2 is installed. During the installation process, the limiting boss 2-2c contacts the edge of the installation hole 1-1a and is continuously pushed upward. After being squeezed upward, the limiting boss 2-2c shrinks inwardly. After shrinking, it is pushed by the thrust to move along the installation hole 1-1a toward the inner step hole 1-1d, until the limiting boss 2-2c moves to the inner step hole 1-1d and is no longer squeezed by the inner wall of the installation hole 1-1a, and then expands outward. After the limiting boss 2-2c is stuck at the inner step hole 1-1d, the installation of the cutter head 2 is completed;

[0040] During disassembly, the push rod 1-6 is pressed downward. After being subjected to the downward pressing force, the push rod 1-6 applies force to the convex buckle 2-2a. The convex buckle 2-2a is disengaged from the inner step hole 1-1d under the downward thrust. The leg force of the convex buckle 2-2a along with the action of the push rod enters the sleeve hole 1-1a. After entering the sleeve hole 1-1a, the convex buckle 2-2a is simultaneously subjected to the inward contraction extrusion force, and continues to apply thrust to the push rod until the convex buckle 2-2a is disengaged from the sleeve hole 1-1a, completing the disassembly of the cutter head 2. At this time, after releasing the pressing of the push rod 1-6, the push rod 1-6 can be automatically reset by the reset force of the compression spring 1-5. When the compression spring 1-5 is not used, the push rod can be directly pushed toward the end cover 1-4 by the cutter head when the cutter head is installed again, until the cutter head is connected to the rotating shaft, thus driving the push rod 1-6 to complete the reset.

[0041] The protection scope of the present utility model is not limited to the above embodiments and their variations. Conventional modifications and replacements made by those skilled in the art based on the contents of this embodiment all fall within the protection scope of the present utility model.
