[0029] Currently available automatic stamping machines typically have multiple stamp holders 117 at the lower end of the head module 100. When changing stamps, the drive shaft of the head module 100 is usually rotated manually to switch between stamps. Frequent stamp changes significantly increase the workload for operators, causing inconvenience in the stamping process.

[0030] To solve the above-mentioned technical problems, this application provides an automatic stamp changing structure and an automatic stamping machine.

[0031] Reference Figure 1 and Figure 4 As shown in the embodiment of this application, an automatic stamp changing structure is provided and configured on the head module 100 of an automatic stamping machine. The head module 100 includes a vertically arranged head drive shaft 101. The automatic stamp changing structure includes a turntable 102 and a paddle mechanism 103. The turntable 102 is located at the upper end of the head drive shaft 101 and is coaxial with the head drive shaft 101. The upper surface of the turntable 102 is provided with a plurality of protrusions 104 distributed circumferentially along the turntable 102. The head module 100 is driven to move the turntable 102 closer to the paddle mechanism 103 in the horizontal direction, so that the protrusions 104 abut against the paddle mechanism 103. The abutting force on the protrusions 104 drives the turntable 102 to rotate the head drive shaft 101.

[0032] It should be noted that in this embodiment, the head module 100 is driven to move horizontally toward the lever mechanism 103, so that the protrusion 104 can abut against the lever mechanism 103. The head module 100 continues to drive the turntable 102 to move in the original direction, and the force generated by the abutment pushes the protrusion 104, causing the turntable 102 to rotate simultaneously. A stamp holder 117 is provided at the lower end of the head drive shaft 101. The turntable 102 drives the stamp holder 117 to rotate synchronously through the head drive shaft 101, realizing stamp switching.

[0033] It should be noted that the protrusion 104 is offset from the center line of the turntable 102 extending in the direction of movement, so as to prevent the paddle mechanism 103 from blocking the protrusion 104 on the turntable 102 and making the turntable 102 unable to continue moving.

[0034] This application provides an automatic stamp-changing structure, including a turntable 102 and a pry mechanism 103. The turntable 102 is located at the upper end of the head drive shaft 101 and is coaxial with the head drive shaft 101. Multiple protrusions 104 are spaced apart along the circumference of the turntable 102 on its upper surface. The head module 100 is driven to move the turntable 102 horizontally towards the pry mechanism 103, causing the protrusions 104 to abut against the pry mechanism 103. The abutting force on the protrusions 104 drives the turntable 102 to rotate the head drive shaft 101. This application utilizes the force generated by the linear horizontal movement of the head module 100 to push the protrusions 104 to rotate, enabling the turntable 102 to drive the head drive shaft 101 to rotate, thereby causing the stamp holder 117 at the lower end of the head drive shaft 101 to rotate synchronously. Compared to the prior art, this application can achieve automatic stamp changing, avoiding manual operation by staff and effectively reducing their workload.

[0035] Reference Figure 2As shown, as an optional implementation, the turntable 102 is provided with a locking structure 105 on its side; the turntable 102 is provided with a plurality of slots 106 distributed circumferentially on its side; the head module 100 is driven to move the turntable 102 away from the paddle mechanism 103 in the horizontal direction, and the locking structure 105 engages with the slots 106 to prevent the turntable 102 from rotating.

[0036] In this embodiment, the locking structure 105 and the slot 106 engage to lock the turntable 102, preventing its rotation. It should be noted that the printing head module 100 can reciprocate between the connecting paddle mechanism 103 and the locking structure 105. On the paddle mechanism 103 side, the printing head module 100 can rotate the turntable 102 to switch stamps, while on the locking structure 105 side, it can be locked in place to achieve automatic stamping.

[0037] The specific structure of the locking structure 105 can be selected by those skilled in the art as needed.

[0038] Reference Figure 2 As shown, exemplarily, the locking structure 105 includes two symmetrically positioned latching rods 107 about the direction of movement of the turntable 102, and a tension spring 108 disposed between the two latching rods 107; the two latching rods 107 form a figure-eight structure with their openings facing the turntable 102; one end of the latching rod 107 near the paddle mechanism 103 is hinged to the head module 100, and both ends of the tension spring 108 are respectively connected to the other ends of the two latching rods 107, so that the two latching rods 107 can clamp the slots 106 on the side of the turntable 102.

[0039] Reference Figure 2 As shown, as an optional implementation, a snap-fit ​​part 109 is provided on the side of the snap-fit ​​rod 107 near the turntable 102, and the snap-fit ​​part 109 can snap into the snap-fit ​​groove 106.

[0040] The snap-fit ​​portion 109 of this embodiment can be inserted into the slot 106. Those skilled in the art can customize the specific shapes of the slot 106 and the snap-fit ​​portion 109 as needed. For example, the snap-fit ​​portion 109 is a semi-cylindrical protrusion, and the slot 106 is a semi-cylindrical groove.

[0041] Reference Figure 3 and Figure 4As shown, in one optional embodiment, the paddle mechanism 103 includes a fixed support 110; a horizontally arranged paddle 111 is located within the fixed support 110; the side of the paddle 111 away from the turntable is rotatably connected to the fixed support 110, and a supporting portion 112 is provided on the side of the paddle 111 near the turntable; a blocking portion 113 and a first elastic component 114 are provided on the fixed support 110, and the blocking portion 113 and the first elastic component 114 are arranged on both sides of the paddle 111 in a direction perpendicular to the moving path of the turntable 102; the first elastic component 114 abuts against one side of the paddle 111, so that the other side of the paddle 111 abuts against the blocking portion 113. The protrusion 104 includes an adjacent first protrusion 104 and a second protrusion 104; the supporting portion 112 abuts against the first protrusion 104, causing the turntable 102 to rotate, so that the second protrusion 104 pushes the paddle 111 to abut against the supporting portion 112.

[0042] Reference Figure 3 and Figure 4 As shown in the embodiment of this application, the specific arrangement of the paddle 111 structure is further disclosed. Through the rotational connection of the paddle 111, the supporting portion 112 located on the side of the paddle 111 closest to the turntable can swing. Through the arrangement of the blocking portion 113 and the first elastic component 114, the paddle 111 can only rotate towards the side of the first elastic component 114, while the other side is blocked by the blocking portion 113. The supporting portion 112 first abuts against the first protrusion 104, causing the turntable 102 to rotate. The second protrusion 104 then pushes the paddle 111 to rotate from the blocking portion 113 side, forming a gap between the blocking portion 113 and the paddle 111. The second protrusion 104 passes through this gap and continues to abut against the supporting portion 112, thus realizing the rotation of the turntable 102.

[0043] It should be noted that the angle formed by the line connecting the first protrusion 104 and the second protrusion 104 to the center of the turntable 102 is the rotation angle of the turntable 102. Similarly, this rotation angle corresponds to the rotation angle of the adjacent stamp holder 117. The positions of the stamp holders 117 and the protrusions 104 on the automatic stamp changing structure are one-to-one. That is to say, the first protrusion 104 corresponds to one stamp holder 117 in the vertical direction, and the second protrusion 104 corresponds to another stamp holder 117 in the vertical direction.

[0044] Reference Figure 1 As shown, for example, there are four protrusions 104, which are evenly spaced around the central axis of the turntable 102. Four stamp holders 117 are provided at the lower end of the head drive shaft 101 and are spaced apart along the circumference of the head drive shaft 101.

[0045] Reference Figure 3 and Figure 4As shown, in one optional implementation, an anti-reverse baffle 115 is provided inside the fixed support 110; the side of the anti-reverse baffle 115 near the turntable 102 is rotatably connected to the fixed support 110, and the rotation axis of the anti-reverse baffle 115 is horizontally set; a second elastic component 116 is provided on the side of the anti-reverse baffle 115 away from the turntable 102, one end of the second elastic component 116 is connected to the anti-reverse baffle 115, and the other end is connected to the fixed support 110; the second elastic component 116 pushes the anti-reverse baffle 115 to contact the plane where the turntable 102 is located.

[0046] It should be noted that the distance between the rotating end of the anti-reverse baffle 115 and the plane of the turntable 102 is greater than the height of the protrusion 104; when the turntable 102 moves to the rotating end of the anti-reverse baffle 115, the protrusion can pass through the gap between the rotating end and the plane of the turntable 102; the distance between the end of the elastic component of the anti-reverse baffle 115 and the plane of the turntable 102 is less than the height of the protrusion, so that when the turntable 102 continues to move, the anti-reverse baffle 115 can prevent the turntable 102 from reversing.

[0047] For example, the first elastic component 114 and the second elastic component 116 are spring elements.

[0048] This application also provides an automatic stamping machine, including a head module 100 and the above-mentioned automatic stamp changing structure; the lower end of the head drive shaft 101 of the head module 100 is provided with a plurality of stamp clamps 117 distributed circumferentially along the head drive shaft 101, and the stamp clamps 117 correspond one-to-one with the protrusions 104 on the automatic stamp changing structure.

[0049] It should be noted that in this embodiment, the stamping operation is performed by using the motor of the existing control head module 100 of the equipment to move horizontally. This embodiment does not require a drive module for driving the rotation of the head shaft and a control component that matches the drive module. Therefore, this application can reduce the production cost of the automatic stamping machine to a certain extent.

[0050] For example, the head module 100 includes a head body and linear slide bars; there are two linear slide bars arranged in parallel, and the head body is slidably mounted on the two linear slide bars, and the head body is driven to move on the linear slide bars by a ball screw or a motor belt assembly.

[0051] In this embodiment, the head module 100 is driven to move linearly in the horizontal direction. With the above-mentioned automatic stamp changing structure, the thrust generated by the linear movement of the head module 100 in the horizontal direction can be used to push the protrusion 104, thereby causing the turntable 102 to rotate. This allows the head drive shaft 101 to drive the stamp clamp 117 to rotate, thus realizing stamp switching.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
