The transmission belt 13 is a synchronous belt or a flat belt 702, and the driven pulley one 11 and the driven pulley two 12 are synchronous pulleys. The packing belt 3 drives the transmission belt 13 to rotate, so as to drive the coil spring mechanism 2 to apply a winding force to the transmission belt 13; and the insertion buckle 31 is locked in the insertion port 511, so as to drive the ratchet mechanism 4 to stop the transmission belt 13 from releasing the winding force.

[0110] The lock core mechanism 5 is arranged, the packing belt 3 is pulled out to bundle the luggage 8, until the insertion buckle 31 is inserted into the insertion port 511 and is locked in the insertion port 511 by the lock core mechanism 5, so as to complete the packing of the luggage 8;

[0111] The ratchet mechanism 4 is arranged, the pawl abuts against the insertion buckle 31 when the insertion buckle 31 is locked in the insertion port 511, the pawl and the ratchet wheel 41 are engaged, the driven pulley one 11 can only drive the transmission belt 13 to rotate in the direction of winding the packing belt 3, and cannot rotate in the direction of pulling out the packing belt 3, the packing belt 3 can be tightened but cannot be pulled out after the insertion buckle 31 is inserted into the insertion port 511 and is locked, that is, the packing belt 3 cannot be lengthened but only can be wound, so as to further enhance the tightness of the packing of the luggage 8, to enhance the difficulty of maliciously unpacking the luggage 8 after being packed, to effectively prevent the malicious unpacking and tearing of the packing belt 3 by the illegal persons to avoid inspection, to improve the interception efficiency of the luggage 8, and to simply and easily operate the packing process and to have high packing efficiency of the luggage 8.

[0112] It is to be noted that the luggage 8 after being bundled and packed cannot be opened at will, and must be controlled by a special key or a special signal (swiping an authority card) to control the lock core mechanism 5 to unlock the insertion buckle 31 and open the luggage 8.

[0113] In some embodiments, the ratchet mechanism 4 further includes a tension spring one 4212 and a rotating pin one 4213, the pawl includes a pawl part 421 and an arc-shaped abutment 422, and the pawl tip 4211 of the pawl is arranged on the pawl part 421.

[0114] The pawl part 421 is connected to one end of the tension spring one 4212 away from the pawl tip 4211, the pawl part 421 is inserted with the rotating pin shaft one 4213, the pawl tip 4211 and the tension spring one 4212 of the pawl part 421 are respectively located on both sides of the rotating pin shaft one 4213;

[0115] The ratchet mechanism 4 further comprises a tension spring two 4222 and a rotating pin shaft two 4223, the tension of the tension spring two 4222 is greater than that of the tension spring one 4212, the arc-shaped top block 422 is provided with a holding part, the holding part is located at one end of the arc-shaped top block 422, the abutting part 4221 is arranged at the other end of the arc-shaped top block 422, the holding part abuts against one end of the pawl part 421 away from the pawl tip 4211 and close to the tension spring one 4212, one end of the arc-shaped top block 422 close to the abutting part 4221 is connected to one end of the tension spring two 4222, the arc-shaped top block 422 is inserted with the rotating pin shaft two 4223, the rotating pin shaft two 4223 is located between the holding part and the abutting part 4221. Preferably, the other end of the tension spring one 4212 is connected to the lock frame 51 of the lock core mechanism 5, both ends of the rotating pin shaft one 4213 are respectively connected to the lock frame 51 of the lock core. Specifically, the pawl is used to prevent the ratchet 41 from reversing, specifically, when the lock core mechanism 5 locks the insertion buckle 31, the transmission belt 13 can only rotate in the direction of tightening the packing belt 3 through the one-way rotation characteristic of the ratchet mechanism 4, effectively preventing the packing belt 3 from being continuously pulled out from the conveying belt after the insertion buckle 31 is locked, causing the packing luggage 8 to be unstable. In detail, referring to Figure 16 When the insertion buckle 31 is not inserted into the insertion port 511, the tension spring one 4212 pulls the pawl part 421 to make the pawl tip 4211 of the pawl part 421 and the tooth groove of the ratchet 41 have a tendency to bite each other, and the tension spring two 4222 pulls the arc-shaped top block 422 to make the holding part of the arc-shaped top block 422 hold the pawl part 421 to stop the pawl tip 4211 of the pawl part 421 and the tooth groove of the ratchet 41 from biting each other, because the tension of the tension spring two 4222 is greater than that of the tension spring one 4212, therefore the pawl part 421 and the ratchet 41 are separated in normal state; referring to Figure 15 When the insertion buckle 31 is inserted into the insertion port 511, the top end part of the insertion buckle 31 will abut against the abutting part 4221 of the arc-shaped top block 422, and make the arc-shaped top block 422 rotate by a certain angle, until the holding part of the arc-shaped top block 422 no longer generates a holding force on the pawl part 421, so that the pawl tip 4211 of the pawl part 421 and the tooth groove of the ratchet 41 bite each other, thereby making the ratchet 41 limit the rotation direction of the driven pulley one 11, finally making the driven pulley one 11 limit the transmission belt 13 to only rotate in the direction of tightening the packing belt 3, and cannot rotate in the direction of lengthening the packing belt 3.

[0116] In some embodiments, the lock cylinder mechanism 5 comprises a lock frame 51, and a lock bolt 52, an unlocking motor 53, a motor shaft 54 and a compression spring 55 arranged on the lock frame 51 respectively, the socket 511 is formed on the lock frame 51, the compression spring 55 is connected to the lock bolt 52 and pops up the lock bolt 52, the unlocking motor 53 drives the motor shaft 54 to press down the lock bolt 52.

[0117] The plug buckle 31 is provided with a lock bolt opening 311, the lock bolt 52 is clamped into the lock bolt opening 311, one end of the tension spring one 4212 away from the pawl is connected to the lock frame 51, both ends of the rotating pin shaft one 4213 are connected to the lock frame 51 respectively, one end of the tension spring two 4222 away from the arc-shaped top block 422 is connected to the lock frame 51, both ends of the rotating pin shaft two 4223 are connected to the lock frame 51 respectively. Specifically, referring to Figure 20 and Figure 22 , the lock frame 51 is used to support and connect other components, the lock frame 51 is connected with the lock bolt 52 through the guide hole, the lock bolt 52 has an upward lifting force at all times under the action of the compression spring 55. When the plug buckle 31 is inserted, due to the slope guide structure of the lock bolt 52, the plug buckle 31 presses down the lock bolt 52, the plug buckle 31 continuously advances forward until the lock bolt opening 311 of the plug buckle 31 is aligned with the lock bolt 52, the lock bolt 52 pops up upward under the reset force of the compression spring 55 and is inserted into the lock bolt opening 311, and the plug buckle 31 is mutually engaged to form a locked state, at this time, the plug buckle 31 cannot be pulled out even if it is pulled with force. At the same time, in the process of inserting the plug buckle 31 into the socket 511 and advancing forward, the arc-shaped top block 422 will be rotated by a certain angle until the arc-shaped top block 422 cancels the holding force on the pawl part 421, so that the claw tip 4211 of the pawl part 421 is engaged with the ratchet wheel 41, and the one-way action principle of the ratchet mechanism 4 is used to realize that after the lock bolt 52 locks the plug buckle 31, the sealing belt can still be tightened, but cannot be pulled out.

[0118] In some embodiments, the coil spring mechanism 2 comprises a coil spring frame 21, and a coil spring 22, a coil spring shaft 23 and a driving gear one 24 arranged on the coil spring frame 21 respectively, the coil spring 22 and the driving gear one 24 are coaxially connected to the coil spring shaft 23 respectively, and the driving gear one 24 is in transmission connection with the driven pulley two 12. Specifically, the winding force generated by the coil spring 22 acts on the driving gear one 24, and then the winding force is transmitted to the driven pulley two 12 through the gear transmission mode, so that the driven pulley two 12 drives the transmission belt 13 to rotate to wind the packing belt 3.

[0119] In some embodiments, the coil spring 22 is provided with two coil springs 22 one and 22 two, and the driving gear one 24 is arranged between the coil spring 22 one and the coil spring 22 two;

[0120] The belt transmission mechanism 1 further comprises a gear shaft two 121, the driven pulley two 12 is provided with two and is coaxially connected to the gear shaft two 121 respectively, the gear shaft two 121 is further coaxially provided with a transmission gear 14, the transmission gear 14 is located between the two driven pulley two 12;

[0121] The belt transmission mechanism 1 further comprises a double gear 15, the transmission gear 14 and the driving gear one 24 are drivingly connected through the double gear 15. Specifically, referring to Figure 17 Two spring reels 22 are respectively installed on both sides of the spring reel frame 21 for storing mechanical energy. When it is necessary to seal and pack the larger luggage 8, it is necessary to pull out a longer packing belt 3, so if the spring reel 22 is energized between the driven pulley two 12 and the driving gear one 24 in a 1:1 manner, the volume of the spring reel 22 to be set is very large, and the sealing lock cannot be made fine, so the double gear 15 is set to realize multi-stage transmission ratio. Referring to Figure 18 , preferably, the pinion of the double gear 15 is engaged with the driving gear one 24, and the gear of the double gear 15 is engaged with the transmission gear 14. Preferably, the double gear 15 is set to realize 2-stage transmission ratio between the driven pulley two 12 and the driving gear one 24, and the total reduction ratio is 1:4, that is, the spring reel 22 rotates 1 reel to drive the driving gear one 24 to rotate 1 circle, and the terminal driven pulley two 12 rotates 4 circles, thus realizing larger energy storage.

[0122] In some embodiments, the spring reel mechanism 2 further comprises a spring reel 22 side cover plate, the spring reel frame 21 is provided with a containing bin 211, the spring reel 22 is arranged in the containing bin 211 and is tightly covered by the spring reel 22 side cover plate. Specifically, the spring reel 22 baffle is used to prevent the spring reel 22 from bouncing out laterally. Referring to Figure 21 , the spring reel two one and the spring reel two two are respectively distributed on both sides of the spring reel frame 21, the outer end of the spring reel 22 is connected with the spring reel frame 21, the inner end of the spring reel 22 is connected with the spring reel shaft 23, and the spring reel 22 is pressed tightly by the spring reel 22 clamping plate. When the spring reel shaft 23 is rotated, the spring reel shaft 23 rotates the inner circle of the spring reel 22 to realize energy storage. In order to prevent the spring reel 22 from bouncing out laterally during rotation, the spring reel 22 is blocked by the spring reel 22 baffle on both sides of the spring reel frame 21 to limit the axial ejection. In any case, after the action force of the spring reel shaft 23 disappears, the spring reel 22 reversely rotates the spring reel shaft 23, releases the mechanical energy to drive the gear to rotate, and realizes the recovery of the sealing belt.

[0123] In some embodiments, the packer 10 further comprises a plurality of anti-over-tightening springs 6, the driven pulley one 11 is provided with a connecting port 112 in the axial direction, the gear shaft one 111 penetrates the connecting port 112, the inner wall of the connecting port 112 is provided with a plurality of spring insertion slots 113 corresponding to the anti-over-tightening springs 6, one end of the anti-over-tightening spring 6 is connected to the outer wall of the gear shaft one 111, and the other end of the anti-over-tightening spring 6 is inserted into the spring insertion slot 113. Specifically, referring to Figure 19 , when tightening, the gear shaft one 111 drives the anti-over-tightening spring 6 to rotate, thereby driving the driven pulley one 11 to rotate to tighten the packing belt 3. When the packing belt 3 is tightened too tightly, the anti-over-tightening spring 6 will be disengaged from the spring insertion slot 113, causing the gear shaft one 111 to drive the anti-over-tightening spring 6 to slip in the connecting port 112 of the driven pulley one 11, effectively preventing the winding spring mechanism 2 from tightening the packing belt 3 too tightly and not stopping the tightening action, which may damage the packing belt 3 or the internal locking mechanism. In detail, an external force can be applied to the driven pulley one 11 or the gear shaft one 111 to achieve external force tightening of the packing belt 3; when the packing belt 3 is tightened by the external force, because the tightening state of the packing belt 3 is unknown, the packing effect may be affected due to insufficient shrinkage of the packing belt 3, resulting in loose and insecure luggage 8; it is also possible that the packing belt 3 is tightened too tightly and the tightening action does not stop, which may damage the packing belt 3 or the internal locking mechanism. Therefore, a plurality of anti-over-tightening springs 6 are fixed outside the tightening shaft (i.e. the gear shaft one 111), the driven pulley one 11 rotates when the anti-over-tightening spring 6 transmits force, and the driven pulley one 11 is uniformly matched with a plurality of spring insertion slots 113 according to the installation position of the anti-over-tightening spring 6. When the gear shaft one 111 rotates, the driven pulley one 11 can also rotate easily, at which time it indicates that the sealing belt has not been tightened, and the tightening action continues; when the driven pulley one 11 is tightened by the packing belt 3, the driven pulley one 11 cannot continue to rotate, and the excess external winding force causes the anti-over-tightening spring 6 to deform, the anti-over-tightening spring 6 disengages from the spring insertion slot 113 on the driven pulley one 11, causing the gear shaft one 111 and the driven pulley one 11 to move relatively, and the anti-over-tightening spring 6 slips in the connecting port 112 of the driven pulley one 11. Through this design, the external force can efficiently and quickly tighten the packing belt 3, and the protection of the various mechanisms and parts after tightening is achieved.

Multiple motors are not required, and only the first motor 401 is required to drive multiple friction wheels to rotate. The rotation of multiple friction wheels makes the rotation of the packing ring 30 more accurate and stable.

[0136] In some embodiments, the packing device further comprises a conveying mechanism 70, which comprises a second motor 701 and a belt 702, and the belt 702 is arranged around the object table 20.

[0138] Another scheme, a method for packing luggage, comprising:

[0139] The packing ring 30 loading step: the mechanical jaw 501 grabs the packing device 10 to translate, so that the pin 301 is inserted into the clasp 31 of the packing device 10;

[0140] The pre-packing step: after the pin 301 is inserted into the clasp 31, the packing ring 30 rotates in the positive direction to drive the pin 301 to pull out the clasp 31, so that the clasp 31 pulls out the packing belt 3 from the packing device 10 to a length suitable for packing the luggage;

Preferably, the positive direction is clockwise, and the reverse direction is counterclockwise.

[0143] In some embodiments, the method further comprises, between the pre-packaging step and the luggage placing step:

[0144] Energy storage step: during the process of pulling out the buckle 31 of the packing belt 3, the transmission belt rotates in the positive direction, so that the coil spring mechanism 2 generates a winding force and acts on the transmission belt, so that the transmission belt has a tendency to wind the packing belt 3;

[0145] The next step of the binding step further comprises:

[0146] Automatic tightening step: the coil spring mechanism 2 releases the winding force, so that the transmission belt rotates in the reverse direction to wind the packing belt 3. The transmission belt rotates in the positive direction, and at the same time drives the driven pulley one and / or the driven pulley two to rotate, to drive the coil spring of the coil spring mechanism 2 to store energy and generate a winding force, to wind the excess packing belt 3, so that the packing belt 3 binds the luggage.

[0147] In some embodiments, the method further comprises, after the automatic tightening step:

[0148] Active tightening step: the tightening shaft 5084 is inserted into the tightening groove 1111, and the tightening motor 5082 drives the tightening shaft 5084 to rotate, to drive the gear shaft one 111 to tighten the transmission belt and the packing belt 3. Specifically, the tightening cylinder 5081 drives the mechanical clamping jaw 501 to move along the guide rail 5013 until the tightening shaft 5084 passes through the external tightening port 76 and is inserted into the tightening groove 1111. When the tightening force of the tightening shaft 5084 is too large, to prevent damage to the parts, the anti-tightening spring and the spring insertion slot are arranged, so that the gear shaft one 111 and the driven pulley one can slide relatively, thereby unloading the excess tightening force of the tightening shaft 5084.

[0149] In some embodiments, the method further comprises, before or after the luggage placing step:

[0150] One-way failure step: after the buckle 31 is pulled out of the insertion port, the ratchet wheel 41 and the pawl are separated, so that the packing belt 3 can be stretched;

[0151] One-way triggering step: when the buckle 31 is inserted into the insertion port, the ratchet wheel 41 and the pawl are engaged, so that the packing belt 3 cannot be stretched. Specifically, it effectively prevents the packing belt 3 from being continuously pulled out of the conveyor belt after the buckle 31 is locked, causing the packed luggage 8 to be unstable.

[0157] The luggage enters the packaging position, and the system judges and gives a start packaging instruction;

[0158] The slip ring rotates counterclockwise until the insertion buckle 31 is reinserted into the insertion port of the packing lock, the lock core mechanism controls the lock tongue to lock the insertion buckle 31, and the packing belt 3 is wound around the luggage;

[0159] The mechanical arm drives the packer 10 to move, so that the insertion buckle 31 is separated from the insertion pin 301, and continues to move downward by a certain distance, at this time, the coil spring mechanism 2 releases the winding force and gradually winds the packing belt 3, until the packer 10 is close to the upper surface of the luggage, the tightening motor 5082 is triggered to rotate to continuously tighten the packing belt 3, and the luggage is further bound firmly;

[0160] After the packaging is completed, the mechanical arm returns to the original position, and waits for the next luggage to enter the sealing and packaging process.

[0161] As can be seen from the above, the present application has the excellent properties described above, and can improve the performance of the prior art and has practicality, and becomes a product with practical value.
