Description

Technical Field

[0001] This application belongs to the field of security inspection equipment technology, and more specifically, relates to a dual-drive sealing mechanism and sealing block. Background Technology

[0002] Baggage sealing devices, also known as baggage packing lockers, are commonly used in public places such as airports, customs, border control, and immigration checkpoints. In public places, if a passenger's baggage contains dangerous items, the risk interception system will detect them and separate them from other normal baggage. For example, in customs and border control, after baggage containing dangerous items is detected, it needs to be marked and sealed with a baggage sealing device to prevent passengers from opening it to take out the dangerous items. Only customs officers can unlock it and open the bag for inspection.

[0003] In the prior art, CN115072174A discloses a luggage packer. To achieve automatic winding, it uses an integrated structure of driven pulley one, driven pulley two, and a transmission belt to wind the packing tape. A complex structure, including an external coil spring and transmission gears, is also provided between driven pulley one and driven pulley two. The buckle can be pulled out from one side of the luggage packer, wraps around the luggage once, and then inserts into the other side of the packer. However, this integrated structure of driven pulley one, driven pulley two, and the transmission belt significantly increases the size of the luggage packer. Furthermore, the buckle protrudes during transport, storage, or sealing, increasing space occupancy. On the other hand, the automatic winding and release speeds of the sealing tape are limited by the multi-stage transmission, reducing speed and affecting work efficiency. Summary of the Invention

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0030] Please refer to the following: Figure 1 The dual-drive sealing mechanism 100 provided in this application embodiment will now be described. The dual-drive sealing mechanism 100 includes:

[0031] The first module 10 includes a first core 11 and a latch 12;

[0032] The second module 20 includes a second core 21 and a locking element 22;

[0033] The sealing tape 30 has its two ends wound onto the first core 11 and the second core 21, respectively.

[0034] The latch 12 can be locked to the locking member 22, so that the first module 10 and the second module 20 are fixed to each other.

[0035] It is understood that, in the unused state, the dual-drive sealing mechanism 100 provided in this application embodiment has the latch 12 locked to the locking member 22, and the first module 10 and the second module 20 fixed to each other. On the one hand, the latch 12 can be hidden inside, and on the other hand, the first module 10 and the second module 20 can be integrated into one, reducing space occupation and facilitating transportation and storage.

[0036] In use, the dual-drive sealing mechanism 100 provided in this application embodiment first unlocks the locking member 22, and then applies external force to the first module 10 or the second module 20, or simultaneously to the first module 10 and the second module 20, to stretch the sealing tape 30. Since the ends of the sealing tape 30 are respectively wound onto the first core 11 and the second core 21, it has the following advantages compared to the integrated sealing mechanism in the prior art:

[0037] Firstly, the first core 11 and the second core 21 can release the sealing tape 30 simultaneously, and with the same amount of force, a longer sealing tape 30 can be stretched. When using cores of the same specification, the dual-drive sealing mechanism 100 provided in this application embodiment can stretch the sealing tape 30 to twice its length with the same amount of force.

[0038] Secondly, to seal luggage and other items, sufficient length needs to be stretched. However, stretching too quickly can cause irreversible damage to the roll core. The dual-drive sealing mechanism 100 provided in this embodiment allows the first module 10 and the second module 20 to release the sealing tape 30 simultaneously during the stretching process, which can significantly increase the stretching speed of the sealing tape 30. When using roll cores of the same specifications, the stretching speed of the sealing tape 30 can be doubled.

[0039] Thirdly, after unsealing, the first module 10 and the second module 20 separate. When the sealing tape 30 is automatically wound up by the internal force of the first core 11 and the second core 21, the first module 10 and the second module 20 can simultaneously wind up the sealing tape 30, which can increase the stretching speed of the sealing tape 30 more quickly. When using cores of the same specification, the automatic winding speed of the sealing tape 30 can be increased by two times.

[0040] Fourthly, the first core 11 and the second core 21 can be used to independently wind up the sealing tape 30. There is no need to set up transmission gears or other devices between the first core 11 and the second core 21, which can increase the storage capacity of the sealing tape 30 and achieve miniaturization.

[0041] Fifthly, in the existing sealing mechanism, the locking buckle 12 is directly connected to the head end of the sealing tape 30. When used in automated sealing equipment, it requires a robotic arm to precisely align the locking buckle 12 with the holes, which is quite difficult and requires high precision. By modularizing the locking buckle 12 with the first core 11, when used in automated sealing equipment, the locking buckle 12 can be moved simply by gripping the entire first module 10, improving convenience and reducing precision requirements.

[0042] Compared with the prior art, the dual-drive sealing mechanism 100 provided in this application simplifies the structure, facilitates storage and transportation, and promotes miniaturization by setting a first module 10 including a first core 11 and a latch 12, and a second module 20 including a second core 21 and a locking element 22. The two ends of the sealing tape 30 are respectively wound onto the first core 11 and the second core 21. On the other hand, it improves the winding speed, release speed and storage capacity of the sealing tape 30.

[0043] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3The first core 11 includes a first rotating shaft 111 and a first inner coil spring 112, and the second core 21 includes a second rotating shaft 211 and a second inner coil spring 212. The first inner coil spring 112 is coaxially arranged with the first rotating shaft 111, and the second inner coil spring 212 is coaxially arranged with the second rotating shaft 211.

[0044] It is understandable that by winding the first rotating shaft 111 with the first inward spring 112, and with the first rotating shaft 111 being coaxially arranged, the space requirement of the first module 10 can be further reduced. Similarly, by winding the second rotating shaft 211 with the second inward spring 212, and with the second rotating shaft 211 being coaxially arranged, the space requirement of the second module 20 can be further reduced.

[0045] For further details, please refer to the following: Figures 1 to 3 The first rotating shaft 111 and the second rotating shaft 211 are arranged in parallel and offset.

[0046] It is understandable that, due to the small internal space, the sealing tape 30 will vibrate during the winding process, and the relative positions of the first module 10 and the second module 20 will be offset. When the sealing tape 30 is wound on the first rotating shaft 111 and the second rotating shaft 211 to a certain extent, the sealing tape 30 may get stuck in the first inner coil spring 112 or the second inner coil spring 212, resulting in the failure of the winding capability. By misaligning the first rotating shaft 111 and the second rotating shaft 211, during the winding of the sealing tape 30, the two ends of the sealing tape 30 will be subjected to a pulling force that deviates from the first inner coil spring 112 or the second inner coil spring 212. Therefore, the sealing tape 30 can be directionally controlled to be wound on the first rotating shaft 111 and the second rotating shaft 211 in a direction that deviates from the first inner coil spring 112 or the second inner coil spring 212, so as to avoid friction or jamming between the sealing tape 30 and the first inner coil spring 112 or the second inner coil spring 212.

[0047] For further details, please refer to the following: Figures 1 to 3 The first rotating shaft 111 is provided with a first active tightening hole 113, and the second rotating shaft 211 is provided with a second active tightening hole 213.

[0048] It is understood that the first active tightening hole 113 and the second active tightening hole 213 are used to connect with mechanical equipment. After the mechanical equipment is inserted into the first active tightening hole 113 and the second active tightening hole 213, the sealing tape 30 is actively tightened by external force to improve the tightening efficiency of the sealing tape 30.

[0049] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 3The first module 10 further includes a first base 13 and a first bearing 14, and the first core 11 is disposed on the first base 13 through the first bearing 14. The second module 20 further includes a second base 23 and a second bearing 24, and the second core 21 is disposed on the second base 23 through the second bearing 24.

[0050] For further details, please refer to the following: Figures 1 to 4 The latch 12 is disposed on the first base 13, the second base 23 is provided with an insertion hole 231, the latch 12 is provided with a locking groove 121, the locking member 22 includes a rotary drive mechanism 221 and a locking member 222, the locking member 222 is disposed on the output end of the rotary drive mechanism 221, after the latch 12 is inserted into the insertion hole 231, the rotary drive mechanism 221 can drive the locking member 222 to lock into the locking groove 121.

[0051] It is understood that the rotary drive mechanism 221 can be a servo motor. After the rotary drive mechanism 221 drives the locking member 222 to engage in the locking slot 121, the first module 10 and the second module 20 are integrated to seal luggage and other items. After the rotary drive mechanism 221 drives the locking member 222 to rotate out of the locking slot 121, the latch 12 is pulled out to complete the unsealing.

[0052] For further details, please refer to the following: Figures 1 to 4 The first base 13 is provided with a pair of first limiting shafts 131 and a first limiting plug 132 arranged in parallel. One end of the first limiting plug 132 is close to the pair of first limiting shafts 131, and the other end extends toward the second base 23. The sealing tape 30 passes between the pair of first limiting shafts 131 and the first limiting plug 132.

[0053] It is understandable that when the dual-drive sealing mechanism 100 is in the locked state, the first limiting plug is squeezed by the second base 23, which can lock the sealing strip 30 in a pair of parallel first limiting shafts 131, thereby preventing the sealing strip 30 in the first module 10 from being stretched.

[0054] For further details, please refer to the following: Figures 1 to 4 The second base 23 is provided with a pair of parallel second limiting shafts 232 and a second limiting plug 233. One end of the second limiting plug 233 is close to the pair of second limiting shafts 232, and the other end extends toward the insertion hole 231. The sealing tape 30 passes between the pair of second limiting shafts 232 and the second limiting plug 233.

[0055] It is understood that when the dual-drive sealing mechanism 100 is in the locked state, the second limiting plug is squeezed by the latch 12, which can lock the sealing tape 30 in a pair of parallel second limiting shafts 232, thereby preventing the sealing tape 30 in the second module 20 from being stretched.

[0056] In this way, when the sealing tapes 30 of the first module 10 and the second module 20 are both locked, neither end of the sealing tape 30 can be stretched, which can prevent luggage and other items from being maliciously unsealed after being sealed, thus improving security.

[0057] Please see Figure 5 This application also provides a sealing 200, which includes a first housing 201, a second housing 202, and a dual-drive sealing mechanism 100 as described above. The first housing 201 is disposed on the first module 10, and the second housing 202 is disposed on the second module 20.

[0058] It is understood that the first housing 201 and the second housing 202 can protect the dual-drive sealing mechanism 100. Since the sealing lock 200 includes the dual-drive sealing mechanism 100, it also has the same beneficial effects as the dual-drive sealing mechanism 100.

[0059] For further details, please refer to Figure 5 The first outer shell 201 is provided with a first clamping and positioning groove 203, and the second outer shell 202 is provided with a second clamping and positioning groove 204.

[0060] It is understandable that the first clamping and positioning groove 203 and the second clamping and positioning groove 204 facilitate the clamping and positioning of the robotic arm.

[0061] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
