[0072] As Figures 1 to 16 shown, the present disclosure provides an automatic sealing device. The automatic sealing device is used to bind the electronic lock 9 to the object to be sealed through the strap B. As Figure 3 、 Figure 4 and Figure 6 shown, the electronic lock 9 includes a strap perforation 91 for passing through the strap B.

[0073] As Figure 1 andFigure 2 As shown, the automatic sealing device mainly includes a carrying device 3, a tape reel device 2, a tape threading frame 5, a lock bin device 8, and a packing machine core 4.

[0074] The carrying device 3 includes a carrying surface for carrying the object to be sealed. The tape reel device 2 is used to store the binding tape B. The tape threading frame 5 is arranged around the carrying surface. A tape guiding groove 5A is arranged along the tape threading frame 5, and the tape guiding groove 5A is used to guide the movement of the binding tape B. The tape threading frame 5 has a break 51. The lock bin device 8 has a receiving cavity 8C for receiving the electronic lock 9 and an electronic lock output port 8B communicating with the receiving cavity 8C. The lock bin device 8 has a lock threading working position. At the lock threading working position, the electronic lock output port 8B is located at the break 51 so that the tape perforation 91 of the electronic lock 9 at the electronic lock output port 8B communicates with the tape guiding grooves 5A on both sides of the break 51 at the break 51. The packing machine core 4 is configured to manipulate the binding tape B stored in the tape reel device 2, so that the binding tape B moves along the tape guiding groove 5A and passes through the tape perforation 91 of the electronic lock 9 when the lock bin device 8 is in the lock threading working position and then binds to the object to be sealed.

[0075] The automatic sealing device according to the embodiment of the present disclosure can use the cooperation of the carrying device 3, the tape reel device 2, the tape threading frame 5 and the tape guiding groove 5A thereon, the lock bin device 8, and the packing machine core 4. The packing machine core 4 can manipulate the binding tape B to quickly bind the electronic lock 9 to the object to be sealed, such as binding to a suspicious luggage. It can realize automatic tape feeding, bundling, improve the sealing efficiency, and reduce the labor cost.

[0076] In the automatic sealing device of some embodiments, the packing machine core 4 is configured to convey the binding tape B along the tape guiding groove 5A, pass the binding tape B through the tape perforation 91, and when the leading end of the binding tape B reaches the target position, retreat the tape to tighten the binding tape B, cut off the binding tape B, and weld the binding tape B passing through the tape perforation 91 and surrounding the object to be sealed into a tape loop. The specific form of the packing machine core 4 is not limited, and various packing machine cores in the prior art that can complete its functions can be adopted.

[0077] In the automatic sealing device of some embodiments, the working position of the lock bin device 8 is adjustably arranged relative to the carrying surface. This setting is beneficial to realizing the stable lock output of the lock bin device 8.

[0078] As Figure 1 and Figure 2 shown, in the automatic sealing device of some embodiments, the automatic sealing device further includes a lock bin position adjusting mechanism 7. The lock bin position adjusting mechanism 7 is drivingly connected to the lock bin device 8 and is configured to drive the lock bin device 8 to act to change the working position of the lock bin device 8 relative to the carrying surface. Setting the lock bin position adjusting mechanism 7 to adjust the working position of the lock bin device 8 is beneficial to realizing the automatic lock output of the lock bin device.

[0079] As Figures 7 to 14 shown, in the automatic sealing device of some embodiments, the lock bin device 8 includes a lock bin main body 81, a first movable stopper 85 and a second movable stopper 86. A receiving cavity 8C is arranged in the lock bin main body 81.

[0080] The first movable stopper 85 is arranged on the lock bin main body 81 and is used for separating the receiving cavity 8C into a first sub-cavity 811C on the side away from the electronic lock output port 8B and a second sub-cavity 812C on the side close to the electronic lock output port 8B. The first movable stopper 85 has a first avoidance working state for enabling the electronic lock 9 in the first sub-cavity 811C to enter the second sub-cavity 812C and a first stop working state for preventing the electronic lock 9 in the first sub-cavity 811C from entering the second sub-cavity 812C.

[0081] The second movable stopper 86 is arranged on the lock bin main body 81 and is located at the electronic lock output port 8B. The second movable stopper 86 has a second avoidance working state for allowing the electronic lock 9 in the second sub-cavity 812C to be output from the electronic lock output port 8B and a second stop working state for preventing the electronic lock 9 in the second sub-cavity 812C from being output from the electronic lock output port 8B.

[0082] By switching the working positions of the first movable stopper 85 and the second movable stopper 86, the lock-out and replenishment of the lock bin device 8 can be controlled.

[0083] As Figures 7 to 14 shown, in the automatic sealing device of some embodiments, the first movable stopper 85 and the second movable stopper 86 are linked. When the first movable stopper 85 is in the first avoidance working state, the second movable stopper 86 is in the second stop working state. When the first movable stopper 85 is in the first stop working state, the second movable stopper 86 is in the second avoidance working state.

[0084] The linkage of the first movable stopper 85 and the second movable stopper 86 can reduce operation errors and better control the lock-out and replenishment of the lock bin device 8.

[0085] As Figures 7 to 14 shown, in the automatic sealing device of some embodiments, the lock bin device 8 further includes a contact 82. The contact 82 is movably arranged relative to the lock bin main body 81. The first movable stopper 85 and the second movable stopper 86 change their own working states according to the relative position between the contact 82 and the lock bin main body 81.

[0086] Setting the contact 82 to be linked with the first movable stopper 85 and the second movable stopper 86 eliminates the need for special operations for the lock-out and replenishment of the lock bin device 8, which is beneficial for the lock bin device 8 to achieve automatic lock-out and replenishment.

[0087] As Figures 7 to 14As shown, in the automatic sealing device of some embodiments, during the process of the contact 82 moving from a position away from the locking bin body 81 towards the side closer to the locking bin body 81 relative to the locking bin body 81, the first movable stop 85 switches from the first avoidance working state to the first stop working state, and the second movable stop 86 switches from the second stop working state to the second avoidance working state. During the process of the contact 82 moving from a position closer to the locking bin body 81 towards the side away from the locking bin body 81 relative to the locking bin body 81, the first movable stop 85 switches from the first stop working state to the first avoidance working state, and the second movable stop 86 switches from the second avoidance working state to the second stop working state.

[0088] The above linkage relationship between the contact 82, the first movable stop 85 and the second movable stop 86 is beneficial for the locking bin device 8 to achieve stable automatic lock ejection and lock replenishment.

[0089] As Figures 7 to 14 shown, in the automatic sealing device of some embodiments, the locking bin device 8 includes a linkage rod 87, a first stop driving part 891 and a second stop driving part 892.

[0090] The linkage rod 87 is located between the first movable stop 85 and the second movable stop 86 and moves synchronously with the contact 82. The first stop driving part 891 is connected to the first movable stop 85 and includes a first sliding groove 8911 located between the first movable stop 85 and the second movable stop 86. The linkage rod 87 passes through the first sliding groove 8911 and is movably arranged along the extending direction of the first sliding groove 8911. The second stop driving part 892 is connected to the second movable stop 86 and includes a second sliding groove 8921 located between the first movable stop 85 and the second movable stop 86. The linkage rod 87 passes through the second sliding groove 8921 and is movably arranged along the extending direction of the second sliding groove 8921. Among them, the first sliding groove 8911 gradually moves away from the locking bin body 81 from the side closer to the first movable stop 85 towards the side closer to the second movable stop 86, and the second sliding groove 8921 gradually approaches the locking bin body 81 from the side closer to the first movable stop 85 towards the side closer to the second movable stop 86.

[0091] Through the linkage rod 87, the first stop driving part 891 and the second stop driving part 892, the linkage relationship between the contact 82, the first movable stop 85 and the second movable stop 86 can be realized, and the linkage relationship is stable and reliable, which is beneficial for the locking bin device 8 to achieve stable automatic lock ejection and lock replenishment.

[0092] As Figures 7 to 14As shown, in the automatic sealing device of some embodiments, the lock bin device 8 further includes a contact guiding structure configured to guide the movement of the contact 82. The contact guiding structure includes a guiding hole H1 and a guiding rod 88. The guiding hole H1 is provided on the lock bin main body 81. The guiding rod 88 is provided on the contact 82, and the guiding rod 88 is slidably engaged with the guiding hole H1.

[0093] The contact guiding structure helps to ensure that the contact 82 moves along a specified path, so as to ensure the stable and reliable linkage relationship between the contact 82 and the first movable stopper 85 and the second movable stopper 86.

[0094] As Figures 7 to 14 shown, in the automatic sealing device of some embodiments, the lock bin device 8 further includes a buffer structure 83 provided at one end of the contact 82 away from the first movable stopper 85. The buffer structure 83 is, for example, a rubber pad. The buffer structure 83 is used to reduce the possible damage caused when the contact 82 presses on the object to be sealed.

[0095] As Figures 7 to 14 shown, in the automatic sealing device of some embodiments, the lock bin device 8 further includes a reset mechanism 84 configured to apply a force to the contact 82 to make it tend to move away from the lock bin main body 81. The reset mechanism 84 includes, for example, a compression spring. The compression spring can be, for example, sleeved on the guiding rod 88. The reset mechanism 84 helps the contact 82 to automatically reset and reduces the operation and control of the contact 82.

[0096] As Figures 7 to 14 shown, in the automatic sealing device of some embodiments, the automatic sealing device further includes a lock bin position adjusting mechanism 7. The lock bin position adjusting mechanism 7 is drivingly connected to the lock bin device 8 and is configured to drive the lock bin device 8 to act to change the working position of the lock bin device 8 relative to the bearing surface. The lock bin device 8 further includes a pressure detection device, which is in signal connection with the lock bin position adjusting mechanism 7. The pressure detection device is configured to detect the pressure detection signal of the pressure applied by the contact 82 to the object to be sealed, and the lock bin position adjusting mechanism 7 determines whether to stop driving the lock bin device 8 to move towards the object to be sealed according to the pressure detection signal. This setting helps to control the pressure when the contact 82 presses on the object to be sealed and helps to reduce the possible damage caused when the contact 82 presses on the object to be sealed.

[0097] In the automatic sealing device of some embodiments, the lock bin device 8 includes at least one of a first stopper guiding structure and a second stopper guiding structure. The first stopper guiding structure is configured to guide the movement of the first movable stopper 85, and the second stopper guiding structure is configured to guide the movement of the second movable stopper 86.

[0098] As Figures 7 to 14As shown, in the automatic sealing device of some embodiments, the first stopper guiding structure includes a first guiding groove G1 provided on the locking chamber main body 81, and the first movable stopper 85 is slidably engaged with the first guiding groove G1. The first guiding groove G1 can be formed by two parallel plates extending outward from the side wall of the locking chamber main body 81. The second stopper guiding structure includes a second guiding groove G2 provided on the locking chamber main body 81, and the second movable stopper 86 is slidably engaged with the second guiding groove G2.

[0099] The first guiding groove G1 can be formed by two parallel plates 812 and 813 extending outward from the side wall of the locking chamber main body 81. The first guiding groove G1 communicates with the accommodating chamber 81C through a first through groove S1 provided on the locking chamber main body 81 for the first movable stopper 85 to pass through.

[0100] The second guiding groove G2 can be formed by two parallel plates 814 and 815 extending outward from the side wall of the locking chamber main body 81. The second guiding groove G2 communicates with the accommodating chamber 81C through a second through groove S2 provided on the locking chamber main body 81 for the second movable stopper 86 to pass through.

[0101] Providing the first stopper guiding structure and the second stopper guiding structure facilitates the first movable stopper 85 and the second movable stopper 86 to reach the accurate working positions when switching to different working states and improves the stability during the working state switching.

[0102] As Figure 6 shown, in the automatic sealing device of some embodiments, the strap guiding groove 5A located upstream of the break 51 along the conveying direction of the strap B includes a first constriction section 52A that gradually contracts toward the break 51; and / or the strap guiding groove 5A located downstream of the break 51 along the conveying direction of the strap B includes a second constriction section 53A that gradually contracts starting from the break 51. This setting facilitates the strap B to smoothly perform the strap perforation 91 of the electronic lock 9 and smoothly enter the strap guiding groove 5A from the strap perforation 91.

[0103] The embodiment of the present disclosure also provides an automatic sealing system. The automatic sealing system includes an electronic lock 9 and an automatic sealing device. The electronic lock 9 includes a strap perforation 91 for passing through the strap B. The automatic sealing device is the automatic sealing device of the embodiment of the present disclosure. The automatic sealing system of the embodiment of the present disclosure has the advantages of the automatic sealing device of the embodiment of the present disclosure.

[0104] In the automatic sealing system of some embodiments, as Figure 3 and Figure 4 shown, at least one end of the strap perforation 91 may include a constriction section 91A that gradually contracts from the outside to the inside. In the automatic sealing system of some embodiments, as Figure 6As shown, the cross-sectional area of the strap perforation 91 gradually decreases from the entrance end to the exit end. The above settings are all conducive to the smooth entry and passage of the strap B through the strap perforation 91 of the electronic lock 9.

[0105] The packing machine core 4 can be, for example, Figure 15 and Figure 16 the packing machine core of the MH-102A full-automatic strapping machine shown or other commercially available packing machine cores to complete actions such as tape feeding, tape retracting, strap welding, and strap cutting. Figure 15 and Figure 16 The strap conveying mechanism of the packing machine core shown conveys the strap B through the tape wheel 41.

[0106] The following further describes the automatic sealing system and its automatic sealing device of the present disclosure in conjunction with Figures 1 to 14 the following.

[0107] The tape reel device 2 is arranged on the side of the equipment frame 1. The tape reel device 2 is used to store the strap B. The selected strap B of the automatic sealing system in this embodiment can be welded by hot melt. The material of the strap B can be PP (Polypropylene) or PET (polyethylene glycol terephthalate).

[0108] The carrying device 3 is arranged above the equipment frame 1. The upper surface of the carrying device 3 serves as the carrying surface for placing the object to be sealed. The carrying device can be a platform. In this case, the carrying surface is the upper surface of the platform; the carrying device can also be a conveying device such as a conveyor belt or a conveying chain. In this case, the carrying surface is the surface of the conveyed object of the conveyor belt, the conveying chain, etc. Figure 1 and Figure 2 In [relevant figures] the carrying surface is the upper surface of the carrying device 3.

[0109] A packing machine core 4 is arranged below the carrying device 3. The packing machine core 4 is used to complete actions such as automatic tape feeding, tape retracting and tightening, strap welding, and strap cutting.

[0110] The threading frame 5 is arranged above the frame 1 and is arranged around the carrying surface of the carrying device 3. A strap guiding groove 5A is arranged on each side of the threading frame 5 facing the carrying surface. The strap perforation 91 of the electronic lock 9 is a square hole with a square cross-section for passing through the strap B. A break 51 is arranged on the threading frame 5. The lock bin device 8 is at the break 51 in its lock threading working position. A plurality of electronic locks 9 can be placed in the accommodation cavity 8C of the lock bin device 8, and the electronic locks 9 can be automatically sent to the position of the break 51 of the threading frame 5, and the strap perforation 91 of the electronic lock 9 is communicated with the strap guiding grooves 5A on both sides of the break 51.

[0111] As shown in Figure 1 and Figure 2In the illustrated embodiment, the strap threading frame 5 may include a plurality of support arms, each support arm being provided with a strap guiding groove 5A. The break 51 may be provided on any one of the plurality of support arms. For example Figure 1 it is provided on the horizontal arm located at the top in Figure 2 it is provided on the vertical arm located on the left side in. The strap guiding groove 5A is interrupted at the break 51, and the strap guiding grooves 5A at both ends of the break 51 may be communicated through the strap perforation 91 of the electronic lock 9.

[0112] The lock bin position adjusting mechanism 7 optionally drives the lock bin device 8 to reciprocate linearly. The lock bin position adjusting mechanism 7 may include a linear actuator drivingly connected to the lock bin device 8, such as a hydraulic cylinder or a linear motor. The lock bin position adjusting mechanism 7 may also include a rotary actuator and a transmission mechanism. The rotary actuator is drivingly connected to the lock bin device 8 through the transmission mechanism. The rotary actuator provides power for the movement of the lock bin device 8, and the transmission mechanism converts the rotary motion of the rotary actuator into a translational motion. The rotary actuator is, for example, a rotary motor or a hydraulic motor, and the transmission mechanism is, for example, a linkage mechanism, a rack and pinion mechanism, a lead screw and nut mechanism, etc.

[0113] In the embodiment of the present disclosure, the lock bin device 8 has the functions of automatically discharging locks and replenishing locks, so as to Figure 1 Taking the illustrated embodiment as an example, when the lock bin device 8 descends under the drive of the lock bin position adjusting mechanism 7 and contacts the surface of the object to be sealed, the electronic lock 9 in the second sub-chamber 812C of the accommodation chamber 8C, that is, the lowermost electronic lock 9, can automatically separate from the electronic lock outlet 8B; when the lock bin device 8 ascends under the drive of the lock bin position adjusting mechanism 7 and disengages from the surface of the object to be sealed, the electronic lock 9 in the first sub-chamber 811C of the accommodation chamber 8C will automatically fill from the first sub-chamber 811C to the second sub-chamber 812C, that is, the lowermost position of the accommodation chamber 81C.

[0114] In this embodiment, the reset mechanism 84 includes a compression spring. The pressure detection device of the lock bin device 8 is used to detect the compression amount of the compression spring. When the contact 82 follows the lock bin device 8 and descends to the surface of the object to be sealed, the components such as the lock bin main body 81 of the lock bin device 8 continue to descend. The contact 82 remains stationary under the action of the object to be sealed. Therefore, the distance between the contact 82 and the lock bin main body 81 gradually decreases (from the perspective of relative motion, the contact 82 moves relative to the lock bin main body 81 in the direction close to the lock bin main body 81). When the compression spring is compressed to a specified position, the lock bin position adjusting mechanism 7 determines according to the pressure detection signal detected by the pressure detection device that it is necessary to stop driving the lock bin device 8 to move towards the object to be sealed, and the lock bin main body 81 stops pressing down. Using the pressure detection signal such as the compression amount of the compression spring to control the lock bin position adjusting mechanism 7 to stop operating can ensure that the maximum pressure when the lock bin device 8 contacts the object to be sealed is consistent for different objects to be sealed, playing a role in protecting the object to be sealed.

[0115] The pressure detection device is not limited to this embodiment. For example, the pressure detection device may also be a piezoelectric sensor disposed on the surface of the contact 82 away from the locking bin main body 81 or on the surface of the buffer structure 83 away from the locking bin main body 81, etc.

[0116] The following uses Figure 1 the automatic sealing device of the illustrated embodiment to illustrate the process of the automatic sealing device of the present disclosure embodiment performing a sealing operation on the object to be sealed.

[0117] At the start of sealing, the locking bin device 8 is in its locking position. The strap B placed on the strap reel device 2 automatically passes through the strap guiding groove 5A of the strap threading frame 5 and the strap perforation 91 in the electronic lock 9 through the tape feeding and retracting module of the strapping machine core 4. After the leading end of the strap B moves into place, the leading end of the strap B is pressed by an ejector body located on the right side of the tape feeding and retracting module of the strapping machine core 4. When the object to be sealed is placed on the bearing surface of the bearing device 3, the locking bin position adjusting mechanism 7 drives the locking bin device 8 and the strap B that has passed through the lowermost electronic lock 9 in the receiving cavity 8C to descend together to the surface of the object to be sealed; when the lowermost electronic lock 9 with the strap B threaded through it in the receiving cavity 8C detaches from the locking bin device and adheres to the surface of the object to be sealed, the tape feeding and retracting module of the strapping machine core 4 starts the tape retracting action until the strap B is tightened. The left ejector body located on the left side of the tape feeding and retracting module of the strapping machine core 4 presses the lower layer of the strap B. The heating sheet of the welding module of the strapping machine core 4 extends into the middle of the two ejector bodies to firmly weld the two layers of the strap B. After the two layers of the strap B are welded into a tape loop, the blade of the cutting module of the strapping machine core 4 cuts the strap B to separate the tape loop and the strap B stored in the strap reel device 2. The locking bin position adjusting mechanism 7 drives the locking bin device 8 to rise to the locking position, and at the same time, the lowermost electronic lock 9 in the first sub-cavity 811C of the receiving cavity 8C falls into the second sub-cavity 812C to become the lowermost electronic lock 9 in the receiving cavity 8C. The strapping machine core 4 automatically feeds the tape again, and the automatic sealing device waits to perform a sealing and binding operation on the next object to be sealed.

[0118] In the embodiment of the present disclosure, the electronic lock 9 is provided with a square hole as the strap perforation 91 for passing through the strap B. The square hole can be used in cooperation with the strap guiding groove 5A to ensure smooth tape entry and exit without jamming. When feeding the tape, the strap B enters the square hole of the electronic lock 9 from the first constriction section 52A of the strap guiding groove 5A, and the cross-sectional area at the entrance of the square hole of the electronic lock 9 is larger than that at the exit, forming a horn-shaped guiding structure, which helps to ensure that the tape will not jam at the entrance of the strap perforation 91 of the electronic lock 9 when feeding the tape. When discharging the tape, the strap B enters the strap guiding groove 5A downstream of the break 51 from the square hole of the electronic lock 9. The strap guiding groove 5A at this place is provided with a second constriction section 53A, which also forms a guiding structure to ensure that the tape will not jam at the strap guiding groove 5A when discharging the tape.

[0119] The following uses Figure 1Taking the automatic sealing device of the illustrated embodiment as an example, the structure of the locking bin device 8 and its actions during the sealing process will be further described.

[0120] The locking bin device includes a locking bin main body 81, a contact 82, a rubber pad serving as a buffer structure 83, a compression spring serving as a reset mechanism 84, an upper stop plate serving as a first movable stop member 85, a lower stop plate serving as a second movable stop member 86, a linkage rod 87, and a guide rod 88, etc.

[0121] The locking bin main body 81 has a hollow cylindrical structure with openings at both the upper and lower ends. The hollow part of the cylindrical structure forms a receiving cavity 8C. The upper opening forms an electronic lock input port 8A, through which the electronic lock 9 can be inserted into the receiving cavity 8C. The lower opening forms an electronic lock output port 8B, from which the electronic lock 9 leaves the receiving cavity 8C. A number of electronic locks 9 can be placed inside the receiving cavity 8C according to requirements.

[0122] On both sides of the locking bin main body 81, an upper stop plate, a lower stop plate, two guide rods 88, and a contact 82 are arranged respectively. On both sides of the upper part of each contact 82, a compression spring is installed, and each compression spring is sleeved on a guide rod 88 respectively. A rubber pad is bonded to the bottom of the contact 82.

[0123] Both the first stop member driving part 891 for driving the upper stop plate to move and the second stop member driving part 892 for driving the lower stop plate to move are plate-shaped, and both the first chute 8911 and the second chute 8921 are long hole-shaped. The first stop member driving part 891 and the second stop member driving part 892 are linked with the contact 82 through a linkage rod 87 connected to the guide rod 88.

[0124] On both sides of the locking bin main body 81, guide holes H1 are provided. The number of guide holes H1 is the same as that of the guide rods 88. The guide holes H1 are located on the bosses 811 on the side walls of the locking bin main body 81. Each guide rod 88 is in sliding fit with a corresponding guide hole H1 and can move axially along the guide hole H1. The contact 82 can move under the guiding action of the guide rods 88 arranged on both sides of the locking bin main body 81 in the guide holes H1. The upper stop plate and the lower stop plate are driven by the linkage rod 87, the first stop member driving part 891, and the second stop member driving part 892 to open and close with the lifting and lowering of the contact 82, and the opening and closing states of the upper stop plate and the lower stop plate are always opposite.

[0125] In this embodiment, a total of two contacts 82 are provided. Two guide rods 88 are connected to each contact 82. The two guide rods 88 on each side are connected by a linkage rod 87. The upper ends of the guide rods 88 are connected together through a connecting frame 88B, thereby connecting the two contacts 82 together.

[0126] A spring retaining ring 88A is provided in the middle of the guide rod 88, and a compression spring is sleeved on the guide rod 88 and is located between the spring retaining ring 88A and the boss 811 on the lock body 81. The upper end of the guide rod 88 passes through the guide hole H1 provided on the boss 811 and is connected to the connecting frame 88B. The connecting frame 88B also limits the extreme position of the contact 82 when it moves away from the lock body 81. When the contact 82 contacts the sealed object and the lock body 81 continues to move downward, the contact 82 stops moving. At this time, from the perspective of relative movement, the contact 82 moves relative to the lock body 81 in the direction close to the lock body 81, and the spring can be compressed by the spring retaining ring 88A. When the external force from the sealed object on the contact 82 disappears, the compression spring causes the guide rod 88 and the contact 82 to move downward through the spring retaining ring 88A.

[0127] Under normal conditions, the contact 82 is in the lowest position due to the downward force of the compression spring, and the second movable stop member, i.e., the lower stop plate, is in the second stop working state, blocking the electronic lock 9 from falling from the second sub-cavity 812C. At the same time, the upper stop plate is in the first avoidance working state, avoiding the electronic lock located in the first sub-cavity 811C, allowing it to move from the first sub-cavity 811C to the second sub-cavity 812C.

[0128] When the locking device 8 descends and the contact 82 contacts the surface of the sealed object, as the locking body 81 continues to descend, the contact 82 approaches the locking body 81 along the guide rod 88 relative to the locking body 81, the compression spring is compressed and shortened, and the lower stop plate gradually switches to the second avoidance working state that allows the electronic lock 9 at the bottom of the accommodating chamber 8C to freely separate from the locking body 81, and the upper stop plate gradually switches to the first stop working state that blocks the electronic lock 9 of the first sub-chamber 811C from falling.

[0129] When the locking device 8 continues to rise and the contact 82 leaves the surface of the sealed object, under the action of the spring force of the compression spring, the contact 82 moves along the guide rod 88 relative to the locking body 81 to the side away from the locking body 81, and the upper stop plate reaches the first avoidance working state, and the lower stop plate reaches the second stop working state. The multiple electronic locks 9 in the first sub-cavity 811C of the accommodating chamber 8C fall freely as a whole, and the electronic lock 9 at the bottom layer of the first sub-cavity 811C changes its position and becomes the electronic lock 9 at the bottom layer of the accommodating chamber 8C. The locking device thus completes the automatic unlocking and relocking process.

[0130] The electronic lock 9 can be connected to the background monitoring system. After the sealed object, such as suspected luggage, is locked and sealed and marked, the background monitoring system immediately starts monitoring the suspected luggage. After the passenger picks up the suspected luggage from the BHS (Baggage Handling System), he cannot open the suspected luggage by himself. After the passenger passes the personal declaration or eliminates the suspicion, the staff will remove the electronic lock.

[0131] After the suspicious luggage is locked and sealed, it can have multiple alarm functions, such as: illegal break-in alarm, leaving the electronic fence area alarm, entering the sensitive area alarm, abnormal lock status alarm, etc. For example, when the electronic lock has a positioning chip, it can track the real-time position of the sealed suspicious luggage. Once the suspicious luggage crosses the boundary, the electronic lock can send relevant information to the background to achieve the leaving the electronic fence area alarm or entering the sensitive area alarm. For another example, the electronic lock can include a break-in sensor and an alarm buzzer at the same time. When the sealed suspicious luggage is broken, the buzzer alarms, and at the same time, the information of the broken luggage and the break-in location are pushed to the background staff.

[0132] Figure 2 The automatic sealing system and the automatic sealing device of the illustrated embodiment are different from Figure 1 the automatic sealing system and the automatic sealing device of the illustrated embodiment in that the setting position of the break 51 is different, and thus the arrangement directions of the lock bin device 8 and the lock bin position adjusting mechanism 7 are different, but their compositions, working processes and working principles can all refer to Figure 1 the relevant descriptions and the relevant drawings of the illustrated embodiment, and will not be repeated here.

[0133] According to the above description, the automatic sealing system and the automatic sealing device of the embodiments of the present disclosure utilize the working principle of the bundling machine to complete actions such as tape feeding, tape retracting, tape binding fusion, and tape binding cutting. The structure is simple and easy to use. When sealing and monitoring the object to be sealed, the bundling and locking speed is fast, which can improve the sealing efficiency, reduce the labor cost, and can be applied in various industries. Its

[0134] The lock bin device 8 has the functions of automatically discharging and replenishing locks, and can keep the pressure applied to the surface of the object to be sealed within a controllable range.

[0135] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present disclosure and not to limit them; although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: it is still possible to modify the specific implementation manners of the present disclosure or perform equivalent replacements for some technical features, and they should all be covered within the scope of the technical solutions claimed by the present disclosure.
