Technical Field

[0001] The utility model relates to the field of seal equipment, in particular to a seal driving mechanism with a seal retracting function and a seal equipment. Background Art

[0002] Existing stamping devices primarily include a device housing, a stamp body, and a driving mechanism for moving the stamp body. A stamp outlet is located below the device housing for the stamp body to enter and exit, and the driving mechanism is a pressing member disposed on the device housing. To perform a stamping operation, a downward pressure is manually applied to the pressing member, causing it to move the stamp body toward the stamp outlet below the device housing and to the outside of the stamp outlet, thereby completing the stamping operation. After the stamping operation is completed, the pressing member can be manually pushed in the opposite direction or a reset spring can be used to apply a reset force to the pressing member, causing the stamp body to be retracted through the stamp outlet and returned to the inside of the device housing.

[0003] However, the existing seal equipment has shortcomings: after the existing driving mechanism drives the seal body to the outside of the seal outlet of the device housing, once someone applies continuous downward pressure to the pressing part in an attempt to prevent the seal body from being retracted into the inside of the device housing, the current driving mechanism cannot retract the seal body into the inside of the seal device housing. This poses the risk of the seal body being exposed to the outside and being illegally stamped. Utility Model Content

[0040] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0041] This embodiment provides a seal driving mechanism with a seal retracting function. Figures 1 to 8 As shown, the seal driving mechanism with a seal retraction function of this embodiment includes a pressing member 2 and a seal retraction mechanism, the pressing member 2 is configured to be slidable back and forth along the axial direction of the device housing 1 of the seal device on the device housing 1, and the pressing member 2 is sleeved on the outside of the device housing 1; the seal retraction mechanism has a controller 31 and a driving device, the controller 31 is configured to receive a start instruction for executing the seal operation and an end instruction for ending the seal operation; the driving device is controlled by the controller 31, and the driving device is configured to cooperate with the pressing member 2 to output a driving force that drives the seal body Q to move from the inside of the device housing 1 to the outside of the device housing 1 or eliminate the driving force.

[0042] That is to say, when the driving device and the pressing piece are in a state of mutual cooperation, the pressing piece and the driving device are in a transmission cooperation state, and the driving device can output a driving force to drive the seal body from the inside of the device shell to the outside of the device shell; when the driving device and the pressing piece are in another state, the pressing piece and the driving device are no longer in a transmission cooperation state, and the driving device eliminates the above-mentioned driving force, that is, it cannot drive the seal body from the inside of the device shell to the outside of the device shell.

[0043] It should be noted that in this embodiment, the start instruction for executing the seal operation and the end instruction for ending the seal operation received by the controller 31 can be set as instructions sent by a remote server or instructions generated by the seal device itself using the seal drive mechanism as needed.

[0044] For example:

[0045] If the above-mentioned "start instruction" and "end instruction" are instructions sent by the remote server S, it can be known that the controller 31 in the seal driving mechanism needs to communicate with the remote server S directly or indirectly;

[0046] If the above-mentioned "start instruction" and "end instruction" are instructions generated by the seal device itself, the seal device may be provided with a control device for controlling the generation of the above-mentioned "start instruction" and "end instruction".

[0047] Specifically, in the seal driving mechanism of this embodiment, see Figure 3 as well as Figures 6-8As shown, the driving device includes an elastic return member 32 and two driving components. The elastic return member 32 is configured to be elastically and telescopically arranged on the inner side of the device housing 1 along the axial direction of the device housing 1. The first end of the elastic return member 32 is configured to be arranged on the inner side of the device housing and above the seal body Q. The second end of the elastic return member 32 is configured to be connected to the seal body Q directly or indirectly. The elastic return member 32 uses a return spring; the two driving components are both arranged on the inner side of the device housing, and the two driving components are symmetrically arranged at the two sides of the seal body Q, for example, one driving component is arranged at the left side of the seal body, and the other driving component is arranged at the right side of the seal body.

[0048] Each drive assembly comprises a driving force output device and a transmission coupling. The driving force output device outputs the driving force. The transmission coupling cooperates with the driving force output device and is in transmission engagement with the pressing member. The transmission coupling is configured to transmit the driving force output by the driving force output device to the seal body directly or indirectly, or to release the transmission engagement with the pressing member. In other words, the transmission coupling is responsible for achieving transmission engagement between the driving force output device and the pressing member.

[0049] Specifically, in the above-mentioned seal driving mechanism, the driving force output device is a driving motor 33, which has a rotating shaft 331. The driving motor 33 is connected to the controller 31 and is configured to output a positive driving force for driving the rotating shaft 331 to rotate in a first direction and a reverse driving force for driving the rotating shaft 331 to rotate in a second direction under the control of the controller 31, wherein the first direction and the second direction are opposite to each other; the transmission coupling member is a locking member 34 that can be coupled with the rotating shaft 331 in transmission, and the locking member 34 is configured to complete a snap connection with the pressing member 2 as the rotating shaft 331 rotates in one direction and to release the snap connection with the pressing member 2 as the rotating shaft 331 rotates in the other direction. For example, for the driving component on one side of the seal body Q, the locking member 34 completes a snap connection with the pressing member 2 as the rotating shaft 331 rotates counterclockwise, and releases the above-mentioned snap connection with the pressing member 2 as the rotating shaft 331 rotates clockwise.

[0050] In this embodiment, the direction of the rotational force of the rotating shaft applied to the locking member 34 when the locking member 34 is released from the transmission engagement with the pressing member 2 is consistent with the direction of the manual pressing force applied to the pressing member 2 during the stamping operation. Specifically, the manual pressing force applied to the pressing member 2 during the stamping operation is directed downwardly in the axial direction of the device housing, and the rotational force of the rotating shaft applied to the locking member 34 when the locking member 34 is released from the transmission engagement with the pressing member 2 is also directed downwardly in the axial direction of the device housing.

[0051] In this embodiment, see Figure 3As shown, the driving device includes four elastic reset members 32, and the four elastic reset members 32 are respectively arranged at the positions of the upper left corner, lower left corner, upper right corner and lower right corner of the seal body Q.

[0052] In order to achieve locking cooperation between the pressing member and the driving device, in this embodiment, the pressing member 2 has a locking groove 20 that is correspondingly engaged and disengaged when the locking member 34 rotates with the rotating shaft 331. Figure 6 and Figure 7 The snap groove 20 is preferably provided on the inner side wall of the pressing member 2 , and the snap groove 20 is formed with a slope section 20 a for engaging and removing the locking member 34 .

[0053] As a method for the seal driving mechanism to drive the seal body to move to the outside of the device housing and to retract it into the inside of the device housing, in this embodiment, see Figure 3 、 Figure 6 、 Figure 7 and Figure 8 As shown, a seal holder W for mounting a seal body Q is provided on the inner side of the device housing 1, a driving device is provided on the seal holder W, and a second end of an elastic reset member 32 is connected to the seal holder W. Of course, because the seal driving mechanism in this embodiment adopts four elastic reset members 32, the four elastic reset members 32 are respectively provided on the four corners of the seal holder W (upper left corner, lower left corner, upper right corner, and lower right corner).

[0054] In order to cooperate with the pressing member to move downward in the axial direction of the device housing to drive the seal body to move out of the device housing through the locking member, see Figures 1 to 3 、 Figure 5 、 Figure 7 and Figure 8 As shown, a sliding track 10 extending axially along the device housing is formed on the device housing 1 of this embodiment. The sliding track 10 is configured to cooperate with the locking member 34 after the pressing member is released so that the locking member slides back and forth axially along the device housing 1.

[0055] As a structural implementation of the locking member, in this embodiment, the locking member 34 includes a latch portion 341 and a stop portion 342. The latch portion 341 engages with or moves out of the latch slot 20; the stop portion 342 is configured to slide back and forth within the sliding area defined by the upper and lower ends of the sliding track 10 when in the unlocked state. Of course, when the stop portion 342 of the locking member 34 is confined within the sliding area defined by the upper and lower ends of the sliding track 10, the stop portion 342 cannot be moved out of the lower end of the sliding track after being subjected to force. This prevents others from attempting to forcibly pull the seal holder located in the device housing out of the device housing through the seal outlet.

[0056] In order to realize the transmission cooperation between the locking member and the rotating shaft, in this embodiment, see Figure 6 、 Figure 7 and Figure 8 As shown, the locking member 34 has a rotation hole (not shown in the figure) through which one end of the rotating shaft 331 passes or penetrates, and the locking member 34 realizes transmission cooperation with the rotating shaft 331 through the rotation hole.

[0057] This embodiment also provides a seal device, which includes a device housing 1 and a seal body Q, wherein the seal body Q is located inside the device housing 1 and is equipped with the aforementioned seal driving mechanism with a seal retracting function.

[0058] The following combination Figures 1 to 8 The working principle of the seal driving mechanism in this embodiment is explained as follows:

[0059] When the controller of the seal driving mechanism receives the start instruction to execute the seal operation, the controller controls the driving motor in the driving assembly on one side to work so that the rotating shaft of the driving motor on the side rotates in the clockwise direction (see Figure 7 ), the locking member also rotates clockwise as the rotating shaft rotates clockwise, so that the locking portion of the locking member is locked in the locking groove of the driving member. At this time, the driving member and the locking member are connected by a snap connection (i.e., transmission cooperation). Then, a downward pressure is manually applied to the driving member along the axial direction of the seal device housing. The driving member drives the seal bracket with the seal body mounted on it to move downward through the locking member, and the locking member moves downward along the sliding track. The elastic reset member in the device housing is continuously stretched by the seal bracket until the seal body moves from the inside of the device housing to the outside of the device housing through the seal outlet, thereby completing the seal operation;

[0060] When the controller of the seal driving mechanism receives the end instruction of the seal operation, the controller controls the drive motor in the drive assembly on the side to work so that the rotating shaft of the drive motor rotates in a counterclockwise manner (see Figures 7 to 8 The latch is then released from the latch groove and the latch is engaged, and the latch is engaged with the latch, and the latch is engaged with the latch, and the latch is engaged with the latch, and the latch is engaged with the latch, and the latch is engaged with the latch, and the latch is engaged with the latch, and the latch is engaged with the latch, and the latch is engaged with the latch, and the latch is engaged with the latch, and the latch is engaged with the latch, and the latch is engaged with the latch, and the latch is engaged with the latch, and the latch is engaged with the latch,

[0061] It should be noted that when the controller of the seal driving mechanism receives the end instruction to end the seal operation, the driving device inside the device shell will automatically move its locking part out of the buckle groove of the pressing part. Even if someone tries to continue to apply downward pressure to the driving part along the axial direction of the seal device shell to try to keep the seal body on the outside of the device shell, the driving part cannot achieve transmission cooperation with the locking part, and the driving part cannot prevent the elastic reset part inside the device shell from driving the seal body to move upward. Moreover, because the artificial pressing force applied to the driving part by an outsider is downward along the axis of the device shell, the direction of the artificial pressing force is consistent with the direction of the rotational force of the rotating shaft that the locking part receives when it moves out of the buckle groove, thereby making the original artificial pressing force that attempts to hinder the retraction of the seal body become an auxiliary force that helps the locking part move out of the buckle groove, thereby avoiding the adverse effect of the artificial pressing force on the retraction movement of the seal body.

[0062] Furthermore, it should be noted that in actual applications, the aforementioned seal drive mechanism may further include the following configuration of the drive assembly as needed: the drive assembly located on one side of the seal body is an electromagnetic device capable of outputting a magnetic attraction force, which achieves transmission coordination with the pressing member by outputting the magnetic attraction force, i.e., the electromagnetic device achieves transmission coordination with the pressing member through magnetic attraction with the pressing member. When the magnetic attraction force output by the electromagnetic device disappears, the electromagnetic device releases its transmission coordination with the pressing member.

[0063] Although the preferred embodiments of the present invention have been described in detail above, it should be clearly understood that various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
