Description

Technical Field

[0001] The present invention relates to the field of seals, and particularly to a fan-door rolling-brush seal. Background Art

[0002] Nowadays, intelligent seals integrate traditional seals, Internet of Things, and communication technologies, combining machinery, electronics, computer control, and Internet technologies. They can effectively manage seals by seal owners. For example, the number of times the seal is stamped and the stamped content can be effectively counted and uploaded to the manager in a timely manner, greatly improving non-compliant or illegal acts such as random stamping and forging seals, and ensuring the safety of enterprise operations and the orderly development of the social economy. However, the above intelligent seals still have the following problems:

[0003] 1. When stamping, it is necessary to dip the seal surface in ink paste, and an ink paste is required, which is inconvenient to use. The ink paste is also likely to dirty hands or the tabletop. At the same time, it is difficult to evenly apply the ink paste or ink on the seal surface of the seal, so the stamped imprints often appear incomplete or unclear.

[0004] 2. When stamping, the seal surface of the seal is generally fixed, so only one type of imprint can be stamped. If multiple types of imprints need to be stamped, multiple seals need to be used. However, in current life, different types of seals are often required to stamp different imprints, so multiple types of seals need to be stored, which is very inconvenient.

[0005] 3. For a re-inking mechanism and a seal device in a Chinese patent application (Application No.: 2021109058578), after stamping, the seal surface can be flipped back into the seal by using an internal reverse mechanism, becoming a widely used product. However, due to the large flipping amplitude of the seal head, the overall volume of the seal is large and it is not convenient to carry; in addition, due to its own structural limitations, its seal surface may still be illegally traced, and the safety is not high.

[0006] 4. For a portable automatic stamping mechanism in a Chinese patent application (Application No.: 2022213990480), it can clamp seals with different diameters and take out the seals to achieve manual stamping, with great flexibility. And to prevent illegal tracing, a normally closed switch door structure similar to a rolling shutter is adopted. When stamping, the shutter quickly opens and closes quickly after stamping, and at the same time, it realizes applying oil to the seal surface. However, the biggest drawback of this solution is that in order to ensure compatibility, the seal volume is too large and it is not convenient to use. Summary of the Invention

[0060] Embodiment 4

[0061] This embodiment is basically the same as Embodiment 1 or Embodiment 2 or Embodiment 3, and this embodiment is an improvement based on Embodiment 1 or Embodiment 2 or Embodiment 3. This embodiment, such as Figure 10 、 Figure 11As shown, the rotating device includes a pair of symmetrically arranged rotating doors. One end of each rotating door is provided with a first connecting shaft 121, and the first connecting shaft 121 is Figure 11 matched with the door opening slot 300 in Figure 11 . Both ends of the rotating door are provided with second connecting shafts 122, and the second connecting shafts 122 are

[0062] matched with the movement slots 301 in

[0063] . In this embodiment, the first connecting shaft 121 moves in the door opening slot 300 to make an upward displacement movement. The second connecting shafts 122 provided at both ends of the rotating door are both connected to the movement slots 301 on the second fixing plate 172 and make a lateral displacement movement on the movement slots 301. The second connecting shaft 122 of one rotating door passes through the movement slot 301 and is connected to the hole on the fixing block 179 at the bottom extension end of the first rack 202, and the other rotating door is connected to the hole on the fixing block 179 at the bottom extension end of the second rack 204. It is driven to open by the first rack 202 and the second rack 204. Compared with Embodiment 1, the opening accuracy of the double-leaf door structure is better and the use effect is better. 2. Manually press the upper shell 3. When the upper shell 3 is pressed down, it drives the middle shell 4 to compress the compression spring 9 sleeved outside the guide post. The middle shell 4 further moves downward, thereby driving the lower pressing frame 101 to move downward. When the lower pressing frame 101 moves downward, it will drive the seal to move downward together. During the whole downward movement process, oil dipping and opening of the rotating door 13 will be completed. Specifically: when the lower pressing frame 101 is pressed down, it drives the contacting rotating shaft 206 to rotate through the connecting piece. The rotation of the rotating shaft 206 drives the first gears 209 sleeved at both ends to rotate, thereby driving the meshing double gears 208 to rotate and driving the second gear 207 to rotate. When the second gear 207 rotates, it will tighten the cable 201. The cable 201 drives the roller brush 14 arranged under the moving bracket and moving in the stroke slot 175 and the groove 211. When moving, it will drive the roller brush 14 to dip the seal surface with printing ink to complete the ink dipping; when the moving bracket moves to the boss 210 at the edge of the groove 211, the moving bracket contacts the boss 210 and drives the first rack 202 to move leftward on the connecting rod 205. The first rack 202 drives the second rack 204 to move rightward on the second stroke protrusion 176 through the meshing rotating wheel. During the movement of the first rack 202 and the second rack 204, it drives the first-layer door 131 to open downward, thereby driving the second-layer door 132, the third-layer door 133, the fourth-layer door 134, and the fifth-layer door 135 to open in sequence, so as to open the rotating door 13 and expose the seal from the outlet, and the stamping operation can be carried out;

[0064] 3. After stamping is completed, release the upper shell 3 by hand. During the upward movement, under the restoring force of the compression spring 9, the upper shell 3 and the middle shell 4 move upward. At the same time, the tension spring 180 pulls back upward, driving the seal to move upward and reset. The middle shell 4 moves upward together with the lower pressing frame 101 and raises the seal into the lower shell 5. At the same time, the driving device and the oil dipping device will reset to the initial position, causing the rotating door 13 to close and the roller brush 14 to reset to its original position, completing the entire reset process;

[0065] 4. Press the switch 2 to control the locking device 12 to lock. The pin shaft at the end of the electromagnet moves towards the middle shell 4, making the pin shaft contact the middle shell 4, and the seal can be locked.
