Description

Technical Field

[0001] The utility model relates to the technical field of stamp stamping machines, in particular to a rotary clamping ink return stamp fixture and a stamp stamping machine. Background Art

[0002] In daily life, when we need to stamp documents, we always do it manually, which is inefficient. Although some existing automatic stamping machines have the kinetic energy to stamp automatically, they have high requirements on the size of the seal and need to be fully compatible with the stamping machine before they can be used. The seal cannot be replaced. At the same time, the automatic stamping machine does not support the installation of manual seals into the automatic stamping machine. This is because the fixture design in the stamping machine is not perfect and cannot fix various types of seals. Utility Model Content

[0025] Embodiment 1

[0026] Combined with Figure 1-3 A rotating clamping ink return stamp fixture includes a main structure 10, on which a rotating ring 11 is provided, and on which a plurality of evenly distributed matching columns 12 are elastically provided. The matching columns 12 are elastically connected to the main structure 10, and the matching columns 12 can undergo slight elastic deformation after being squeezed by external force, and can automatically return to their original state after the external force disappears.

[0027] The main structure 10 is a cylindrical shell, and a cavity for placing a seal is provided inside the main structure 10 .

[0028] The rotating ring 11 forms an extrusion fit with the matching column 12 by rotating. The rotating ring 11 is rotated clockwise or counterclockwise to realize the up and down movement of the rotating ring 11 on the main structure 10. In the initial state, the rotating ring 11 is located on the upper side of the main structure 10, and the matching column 12 is located on the lower side of the main structure 10. When the rotating ring 11 gradually moves downward with its own rotation, it will gradually squeeze the matching column 12. The matching column 12 will be elastically deformed toward the inside of the main structure 10 when it is squeezed.

[0029] A plurality of the matching columns 12 are combined to form a group of matching columns, and the groups of matching columns are evenly distributed and arranged around the main structure 10. Preferably, three matching columns 12 form a group, and each main structure 10 is provided with four groups of matching columns.

[0030] A clamping plate 14 is fixedly mounted on the inner side of the plurality of matching columns 12 in the same group. The clamping plate 14 is made of silicone and is used to fix a stamp placed in the inner cavity of the main structure 10 .

[0031] Each group of matching posts 12 includes at least one matching post 12 having an inclined protrusion 13 on its outer surface.

[0032] The inclined protrusion 13 is inclined outward from top to bottom, and the matching protrusion 12 is used to cooperate with the rotating ring 11. When the rotating ring 11 gradually moves downward from the upper side of the main structure 10 by rotating, the rotating ring 11 will gradually contact the inclined protrusion 13 as it moves downward. After the rotating ring 11 is released from the inclined protrusion 13, the inclined protrusion 13 will be squeezed, so that the inclined protrusion 13 drives the matching column 12 to elastically deform into the inside of the main structure 10, thereby making the matching column 12 tilt into the main structure 10. Since the protruding part of the inclined protrusion 13 gradually increases from top to bottom, while the contact part between the rotating ring 11 and the inclined protrusion 13 gradually increases, the rotating ring 11 will gradually increase the tilt of the matching column 12 into the inside of the main structure 10 by squeezing the inclined protrusion 13.

[0033] When the matching column 12 contracts and tilts inward, it drives the clamping plate 14 to tilt inward. The clamping plate 14 tilts inward to clamp and fix the stamp placed inside the main structure 10.

[0034] Therefore, the degree of inward inclination of the matching column 12 becomes the degree of squeezing of the seal by the clamp 14, and then, the degree of up and down movement formed by the rotation of the rotating ring 11 can realize the fixing and loosening of the seal inside the main structure 10, thereby realizing the fixing and loosening of the seal by rotating the rotating ring 11, and because the rotating ring 11 can control its up and down movement distance by rotation, the rotating ring 11 can fix the seals of different diameters or sizes placed in the main structure 10 by the up and down movement distance.

[0035] The clamping plate 14 is made of silicone. Since silicone itself is elastic and has a large friction force, stamps of different materials can fully fit with the clamping plate 14, thereby achieving fixation of the stamp.

[0036] An external thread 15 is provided on the upper side of the main structure 10, and an internal thread cooperating with the external thread 15 is provided inside the rotating ring 11. The rotating ring 11 realizes its up and down movement by threaded cooperation with the main structure 110. The threaded cooperation can linearly control the moving distance and moving position of the rotating ring 11, and can better realize the clamping and fixing of seals of different sizes.

[0037] The rotating ring 11 rotates downward to the position of two-thirds of the external thread 15 to completely cover the matching column 12. This setting is to prevent the rotating ring 11 from falling off from the external thread 15 or thread slippage, and also helps to reduce the height of the main structure 10.

[0038] Embodiment 2

[0039] like Figure 4 As shown, a stamping machine comprises a casing 30, in which the rotating ink return stamp clamp of Example 1 is arranged, and a power structure is arranged on the top of the casing 30, and the power structure drives the rotating ink return stamp clamp of Example 1 to realize up and down reciprocating motion. The power structure can be realized by a structure capable of realizing reciprocating motion, such as a screw structure, a cam structure, and a connecting rod structure. In the rotating ink return stamp clamp of Example 1, a connecting cover 31 for connecting to the power structure is arranged on the top of the main structure 10, and the rotating ink return stamp clamp is fixedly connected to the power structure through the connecting cover 31, so that after the power structure is turned on, the rotating ink return stamp clamp is driven by the power structure to realize up and down movement, thereby realizing the stamping action.

[0040] A support rod 33 may also be provided in the main structure 10, and a seal housing 34 is directly provided at the bottom of the support rod 33. A gasket and a seal are respectively provided in the seal housing 34. The gasket may be set to different thicknesses so that the bottom end surfaces of seals of different thicknesses are at the same height, so as to achieve the requirements of efficient and good use of stamping.

[0041] The seal housing 34 is used to fix the seal with only the seal face, and the seal face used can be changed at will. The support rod 33 is fixed in the main structure 10 and is clamped and fixed by the clamping plate 14.

[0042] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
