[0071] The present invention is described in detail below with reference to the accompanying drawings.

[0072] like Figures 1 to 13 As shown, in an embodiment of the present invention, a luggage packer is provided, characterized in that it includes:

[0073] A belt transmission mechanism 1, comprising a driven pulley 11, a driven pulley 2 12 and a transmission belt 13, wherein the driven pulley 11 and the driven pulley 2 12 are connected to each other via the transmission belt 13;

[0074] A coil spring mechanism 2, wherein the coil spring mechanism 2 is transmission-connected to the driven pulley 1 11 and / or the driven pulley 2 12;

[0075] A strapping belt 3, one end of which is wound around the transmission belt 13;

[0076] A buckle 31, to which the other end of the strapping tape 3 is connected;

[0077] A ratchet mechanism 4, comprising a ratchet 41 and a pawl, wherein the ratchet 41 is coaxially connected to the driven pulley 11; and

[0078] A lock core mechanism 5, wherein the lock core mechanism 5 is provided with a socket 511 matching the buckle 31;

[0079] The pawl is provided with an abutment portion 4221 that is abutted by the buckle 31, causing the pawl tip 4211 to engage the tooth groove of the ratchet wheel 41. The abutment portion 4221 is located immediately inside the buckle 31. Specifically, the transmission belt 13 is a synchronous belt or a flat belt, and the driven pulleys 11 and 12 are synchronous pulleys. The strapping belt 3 rotates the transmission belt 13, driving the winding spring mechanism 2 to apply a rewinding force to the transmission belt 13. The buckle 31 locks into the socket 511, driving the ratchet mechanism 4 to stop the transmission belt 13 from releasing the rewinding force.

[0080] In this solution, by providing a belt transmission mechanism 1 and a winding spring mechanism 2, and winding the strapping belt 3 around the transmission belt 13, when the buckle 31 is pulled to pull the strapping belt 3 out of the transmission belt 13, the winding spring mechanism 2 will generate elastic potential energy and apply a winding force to the transmission mechanism, causing the transmission belt 13 to have a rewinding tendency. When the tension applied to the strapping belt 3 is released, the transmission belt 13 will automatically rewind the strapping belt 3.

[0081] The lock core mechanism 5 is provided, and the strapping belt 3 is pulled out to tie the luggage 8 until the buckle 31 is inserted into the socket 511 and locked in the socket 511 by the lock core mechanism 5, thereby completing the sealing and packing of the luggage 8;

[0082] When the cam 31 is locked in the slot 511, the cam 31 will hit the pawl and engage with the ratchet 41, so that the driven pulley 11 can only drive the transmission belt 13 to rotate in the direction of winding the strapping belt 3, but cannot rotate in the direction of pulling out the strapping belt 3. After the cam 31 is inserted into the slot 511 and locked, the strapping belt 3 can still be tightened but cannot be pulled out, that is, the strapping belt 3 cannot be further extended but can only be wound, so as to further strengthen the firmness of the luggage 8 packaging, thereby increasing the difficulty of malicious unpacking of the luggage 8 after packaging, effectively preventing someone from maliciously disassembling and tearing the strapping belt 3 to evade inspection, and improving the efficiency of intercepting the luggage 8. The packaging process is simple and easy to operate, and the efficiency of packaging the luggage 8 is high.

[0083] It should be noted that the bundled and packed luggage 8 cannot be opened at will. A special key or a special signal (swipe authority card) must be used to control the lock core mechanism 5 to unlock the buckle 31 and open the luggage 8.

[0084] In some embodiments, the ratchet mechanism 4 further includes a tension spring 4212 and a rotation pin 4213. The end of the pawl near the pawl tip 4211 is connected to one end of the tension spring 4212. The pawl is inserted with the rotation pin 4213. The pawl tip 4211 and the tension spring 4212 are both located on one side of the rotation pin 4213, and the abutting portion 4221 is located on the other side of the rotation pin 4213. Preferably, the other end of the tension spring 4212 is connected to the lock frame 51 of the lock cylinder mechanism 5, and both ends of the rotation pin 4213 are respectively connected to the lock frame 51 of the lock cylinder. Specifically, the pawl is used to prevent the ratchet 41 from rotating backwards. Specifically, when the lock core mechanism 5 locks the buckle 31, the unidirectional rotation characteristic of the ratchet mechanism 4 forces the transmission belt 13 to rotate only in the direction of tightening the strap 3. This effectively prevents the strap 3 from continuing to be pulled from the conveyor belt after the buckle 31 is locked, causing the packed luggage 8 to become unstable. Specifically, when the buckle 31 is not inserted into the socket 511, the tension spring 1 4212 pulls the pawl, causing the pawl's pawl tip 4211 and the ratchet 41 to normally separate. When the buckle 31 is inserted into the socket 511, the top of the buckle 31 abuts against the pawl's abutting top 4221, causing the pawl to rotate a certain angle around the rotating pin 1 4213 as a rotation axis until the pawl engages with the ratchet 41, causing the ratchet 41 to restrict the rotation direction of the driven pulley 1 11. Ultimately, the driven pulley 1 11 restricts the transmission belt 13 from rotating only in the direction of tightening the strap 3, and not in the direction of lengthening the strap 3.

[0085] In some embodiments, the ratchet mechanism 4 further includes a tension spring 4212 and a rotating pin 4213, the pawl includes a pawl portion 421 and an arched top block 422, and the pawl tip 4211 of the pawl is disposed on the pawl portion 421;

[0086] One end of the pawl portion 421 away from the claw tip 4211 is connected to one end of the tension spring 1 4212 , and the pawl portion 421 is inserted with the rotation pin 1 4213 . The claw tip 4211 of the pawl portion 421 and the tension spring 1 4212 are respectively located on both sides of the rotation pin 1 4213 ;

[0087] The ratchet mechanism 4 also includes a second tension spring 4222 and a second rotating pin 4223. The tension of the second tension spring 4222 is greater than the tension of the first tension spring 4212. The bow-shaped top block 422 is provided with a supporting portion, which is located at one end of the bow-shaped top block 422. The abutting portion 4221 is arranged at the other end of the bow-shaped top block 422. The supporting portion abuts against an end of the pawl portion 421 away from the pawl tip 4211 and close to the first tension spring 4212. One end of the bow-shaped top block 422 close to the abutting portion 4221 is connected to one end of the second tension spring 4222. The bow-shaped top block 422 is inserted with the second rotating pin 4223, and the second rotating pin 4223 is located between the supporting portion and the abutting portion 4221. Preferably, the other end of the tension spring 1 4212 is connected to the lock frame 51 of the lock core mechanism 5, and the two ends of the rotating pin 1 4213 are respectively connected to the lock frame 51 of the lock core. Specifically, the pawl is used to prevent the ratchet 41 from rotating backwards. Specifically, when the lock core mechanism 5 locks the buckle 31, the unidirectional rotation characteristic of the ratchet mechanism 4 allows the transmission belt 13 to rotate only in the direction of tightening the strapping 3, effectively preventing the strapping 3 from continuing to be pulled out of the conveyor belt after the buckle 31 is locked, causing the packed luggage 8 to become unstable. For details, refer to Figure 6 When the buckle 31 is not inserted into the socket 511, the tension spring 1 4212 pulls the pawl portion 421 so that the claw tip 4211 of the pawl portion 421 and the tooth groove of the ratchet 41 tend to engage with each other, and the tension spring 2 4222 pulls the arched top block 422 so that the supporting portion of the arched top block 422 is supported on the pawl portion 421 to prevent the claw tip 4211 of the pawl portion 421 and the tooth groove of the ratchet 41 from engaging with each other. Since the tension of the tension spring 2 4222 is greater than the tension of the tension spring 1 4212, the pawl portion 421 and the ratchet 41 are normally separated. Figure 5 When the buckle 31 is inserted into the socket 511, the top end of the buckle 31 will abut against the abutting top 4221 of the arched top block 422, and the arched top block 422 will rotate a certain angle until the supporting portion of the arched top block 422 no longer exerts a supporting force on the pawl portion 421, so that the claw tip 4211 of the pawl portion 421 and the tooth groove of the ratchet 41 are engaged, thereby causing the ratchet 41 to limit the rotation direction of the driven pulley 11. Finally, the driven pulley 11 limits the transmission belt 13 to rotate only in the direction of tightening the strapping belt 3, but not in the direction of lengthening the strapping belt 3.

[0088] In some embodiments, the lock core mechanism 5 further includes a lock frame 51 and a lock tongue 52, an unlocking motor 53, a motor shaft 54, and a compression spring 55, which are respectively provided on the lock frame 51. The socket 511 is formed on the lock frame 51. The compression spring 55 is connected to the lock tongue 52 and bounces the lock tongue 52. The unlocking motor 53 drives the motor shaft 54 ​​to press down the lock tongue 52.

[0089] The latch 31 is provided with a latch opening 311, into which the latch 52 engages. The end of the tension spring 1 4212, distal from the pawl, is connected to the lock frame 51, and both ends of the rotation pin 1 4213 are respectively connected to the lock frame 51. Specifically, based on the aforementioned embodiment employing only a pawl without the arched top block 422, a further embodiment of the lock core mechanism 5 will be described. This further enhances the difficulty of malicious unpacking of the packed luggage 8, effectively preventing malicious opening and tearing of the strapping 3 to evade inspection, and further improving the efficiency of intercepting the luggage 8. The packing process is simpler and easier to operate, further improving the efficiency of packing the luggage 8.

[0090] In some embodiments, the lock core mechanism 5 includes a lock frame 51 and a lock tongue 52, an unlocking motor 53, a motor shaft 54, and a compression spring 55, which are respectively provided on the lock frame 51. The socket 511 is formed on the lock frame 51. The compression spring 55 is connected to the lock tongue 52 and bounces the lock tongue 52. The unlocking motor 53 drives the motor shaft 54 ​​to press the lock tongue 52 downward.

[0091] The buckle 31 is provided with a lock tongue opening 311, the lock tongue 52 is inserted into the lock tongue opening 311, the end of the tension spring 1 4212 away from the pawl is connected to the lock frame 51, the two ends of the rotating pin 1 4213 are respectively connected to the lock frame 51, the end of the tension spring 2 4222 away from the arched top block 422 is connected to the lock frame 51, and the two ends of the rotating pin 2 4223 are respectively connected to the lock frame 51. Specifically, refer to Figure 10 and Figure 12 The lock frame 51 is used to support and connect other components. The lock frame 51 is connected to the lock tongue 52 through a guide hole. The lock tongue 52 is constantly forced to lift up under the action of the compression spring 55. When the plug buckle 31 is inserted, the plug buckle 31 presses down the lock tongue 52 due to the inclined guide structure of the lock tongue 52. The plug buckle 31 continues to move forward until the lock tongue opening 311 of the plug buckle 31 is aligned with the lock tongue 52. The lock tongue 52 bounces upward under the restoring force of the compression spring 55 and inserts into the lock tongue opening 311, interlocking with the plug buckle 31 to form a locked state. At this time, even if the plug buckle 31 is pulled hard, it will not be pulled out. At the same time, when the buckle 31 is inserted into the socket 511 and pushed forward, the arched top block 422 is pushed to rotate a certain angle until the arched top block 422 releases the supporting force on the pawl portion 421, so that the claw tip 4211 of the pawl portion 421 engages with the ratchet 41. By utilizing the principle of the one-way action of the ratchet mechanism 4, after the lock tongue 52 locks the buckle 31, the sealing tape can be tightened but cannot be pulled out.

[0092] In some embodiments, the coiling spring mechanism 2 includes a coiling spring frame 21, and a coiling spring 22, a coiling spring shaft 23, and a driving gear 1 24, each of which is disposed on the coiling spring frame 21. The coiling spring 22 and the driving gear 1 24 are coaxially connected to the coiling spring shaft 23, and the driving gear 1 24 is in transmission connection with the driven pulley 2 12. Specifically, the winding force generated by the coiling spring 22 acts on the driving gear 1 24, which then applies the winding force to the driven pulley 2 12 through a gear transmission method, causing the driven pulley 2 12 to drive the transmission belt 13 to rotate to wind up the strapping tape 3.

[0093] In some embodiments, the coil springs 22 are provided with two, namely coil spring 22 1 and coil spring 22 2, and the driving gear 1 24 is provided between the coil spring 22 1 and the coil spring 22 2;

[0094] The belt transmission mechanism 1 further includes a second gear shaft 121, and the second driven pulleys 12 are provided with two and are coaxially connected to the second gear shaft 121. The second gear shaft 121 is also coaxially provided with a transmission gear 14, and the transmission gear 14 is located between the two second driven pulleys 12;

[0095] The belt transmission mechanism 1 further includes a double gear 15, and the transmission gear 14 and the driving gear 24 are connected to each other through the double gear 15. Figure 7 Two coil springs 22 are mounted on either side of the coil spring frame 21 to store mechanical energy. When packing larger luggage 8, a longer strap 3 needs to be pulled out. Therefore, if the coil springs 22 are stored in a 1:1 ratio between the driven pulley 2 12 and the driving gear 1 24, the required coil springs 22 would be very large, making it difficult to achieve a precise seal. Therefore, a multi-stage transmission ratio is achieved by installing a double gear 15. Figure 8 Preferably, the small gear of the double gear 15 meshes with the driving gear 1 24, and the large gear of the double gear 15 meshes with the transmission gear 14. Preferably, by providing the double gear 15, a two-stage transmission ratio is achieved between the driven pulley 2 12 and the driving gear 1 24, totaling a reduction ratio of 1:4. That is, when the coil spring 22 rotates once, the driving gear 1 24 rotates once, while the driven pulley 2 12 at the end rotates four times, thereby achieving a large energy storage.

[0096] In some embodiments, the coil spring mechanism 2 further includes a side cover for the coil spring 22. The coil spring frame 21 is provided with a storage compartment 211. The coil spring 22 is provided in the storage compartment 211 and is tightly covered by the side cover for the coil spring 22. Specifically, the baffle for the coil spring 22 is used to prevent the coil spring 22 from popping out laterally. Figure 11Coil springs 22-1 and 22-2 are located on either side of coil spring frame 21. The outer end of coil spring 22 is connected to coil spring frame 21, while the inner end of coil spring 22 is connected to coil spring shaft 23, which is clamped in place by coil spring 22 clamps. When coil spring shaft 23 is rotated, it winds the inner coil of coil spring 22, storing energy. To prevent coil spring 22 from ejecting laterally during rotation, coil spring baffles on either side of coil spring frame 21 block coil spring 22, limiting axial ejection. Conversely, when the force exerted on coil spring shaft 23 dissipates, coil spring 22 winds the shaft in the opposite direction, releasing mechanical energy that drives the gears to rotate, thus retrieving the sealing tape.

[0097] In some embodiments, a plurality of anti-overtightening spring sheets 6 are further included, the belt transmission mechanism 1 further includes a gear shaft 111, a connecting port 112 is provided in the axial direction of the driven pulley 11, the gear shaft 111 is connected to the connecting port 112, the inner wall of the connecting port 112 is provided with a plurality of spring sheet slots 113 corresponding to the anti-overtightening spring sheets 6, one end of the anti-overtightening spring sheet 6 is connected to the outer wall of the gear shaft 111, and the other end of the anti-overtightening spring sheet 6 is inserted into the spring sheet slot 113. Specifically, refer to Figure 9During tightening, the gear shaft 111 drives the anti-overtightening spring piece 6 to rotate, thereby driving the driven pulley 11 to rotate and tighten the strap 3. When the strap 3 is overtightened, the anti-overtightening spring piece 6 will disengage from the spring piece slot 113, causing the gear shaft 111 to drive the anti-overtightening spring piece 6 to slip within the connection port 112 of the driven pulley 11, effectively preventing the winding spring mechanism 2 from overtightening the strap 3 without stopping the tightening action, thereby damaging the strap 3 or the internal mechanism of the lock. Specifically, an external force can be applied to the driven pulley 11 or the gear shaft 111 to achieve external tightening of the strap 3. When tightening the strap 3 by external force, because the tightening state of the strap 3 is unknown, the strap 3 may not be contracted enough, affecting the packing effect, causing the luggage 8 to be loose and unstable. It is also possible that the strap 3 is overtightened without stopping the tightening action, thereby damaging the strap 3 or the internal mechanism of the lock. Therefore, a plurality of anti-overtightening spring clips 6 are fixed on the outside of the tightening shaft (i.e., gear shaft 111). When the anti-overtightening spring clips 6 transmit force, the driven pulley 11 rotates. The driven pulley 11 has a plurality of spring clip slots 113 evenly distributed according to the installation position of the anti-overtightening spring clips 6. When the gear shaft 111 rotates, the driven pulley 11 can still rotate easily, which means that the sealing belt has not been tightened yet, and the tightening action continues; when the driven pulley 11 is tightened by the strapping belt 3, the driven pulley 11 cannot continue to rotate, and the excess external winding force causes the anti-overtightening spring piece 6 to deform, and the anti-overtightening spring piece 6 disengages from the spring piece slot 113 on the driven pulley 11, causing the gear shaft 111 and the driven pulley 11 to move relative to each other, so that the anti-overtightening spring piece 6 slips in the connecting port 112 of the driven pulley 11. Through this design, the external force can be used to efficiently and quickly tighten the strapping belt 3, and the protection of various mechanism components after tightening can be achieved.

After bundling and packing, the luggage 8 cannot be opened at will. A special key or a special signal (swiping an authority card) must be used to control the lock core mechanism 5 to unlock the buckle 31 and open the luggage 8. The positioning chip board 7 can actively send signals to the outside in real time for positioning, and track and locate the movement trajectory of the luggage 8, so as to facilitate the staff to track and inspect the luggage 8, further effectively control and intercept the luggage 8 with prohibited items, and more effectively prevent people from abandoning the luggage 8 and evading inspection.
