The working process of the invention is as follows: in the initial state, the central axis position of the roller shaft A4 is higher than the central axis position of the roller shaft B10, the support plate 1 tilts, the fixture block A40 contacts with the fixture block B41, and the volute spring B37 precompresses. The holding rod 45 is parallel to the roller shaft A4, and one end of the sliding rod 49 is inserted into a limit groove 44 on the fixed shaft to lock the parallel state of the holding rod 45 and the roller shaft A4. Clamp a22 and clamp B34 compress against each other, and both scroll springs a24 are in a pre-compressed energy storage state. Spring A19, and spring C50 are in a compressed charged state, and spring B35 and spring D68 are in an extended charged state. The distance between the slide block A29 and the slide block B57 from the roller A4 reaches the farthest limit, and the distance between the blade 66 and the counter plate 7 reaches the farthest limit. The distance of the blade 66 from the counter strip 7 reaches the furthest limit. The wire 54 is in a taut state.

When the invention is needed to seal the matched packing box 70, the adhesive tape 11 is firstly wound on the roller B10, then one end of the adhesive tape 11 is pulled to pass through the space between the blade 66 and the chopping board strip 7 from bottom to top and cross and bypass the roller 5, so that the adhesive surface of the adhesive tape 11 wound on the roller 5 is turned outwards, then the adhesive tape 11 sequentially bypasses the tensioning roller 21 to reach the clamping plate A22 and the clamping plate B34, the sliding block A29 is pushed to slide towards the roller A4, and the spring B35 is further stretched to store energy. The slide block A29 drives the clamp plate A22 to swing away from the clamp plate B34 through the driving block 27, the round pin A26, the swinging block 25 and the rotating shaft A23. The tail end of the adhesive tape 11 is pulled between the clamping plate A22 and the clamping plate B34, the acting force on the sliding block A29 is removed, the sliding block A29 is reset instantly under the reset action of the spring B35, the sliding block A29 drives the driving block 27 to reset instantly, the rotating shaft A23 rotates under the reset action of the two scroll springs A24, the rotating shaft A23 drives the clamping plate A22, the swinging block 25 and the round pin A26 to swing back and reset, and the clamping plate A22 presses the tail end of the adhesive tape 11 on the clamping plate B34 instantly. Due to the action of the spring B35 and the scroll spring A24, the clamping plate A22 tightly presses the end of the adhesive tape 11 against the clamping plate B34, so that the end of the adhesive tape 11 is effectively pulled, and the adhesive tape 11 is prevented from being effectively wound on the roller 5 after a human hand is separated from the adhesive tape 11.

In the process of pulling the tail end of the adhesive tape 11 to the clamping plate A22 and the clamping plate B34, the adhesive tape 11 acts on the tension roller 21, so that the tension roller 21 drives the two inner rods 17 to respectively and simultaneously retract towards the corresponding outer sleeves 15 through the roller shaft C20, and the springs A19 in the outer sleeves 15 are further compressed to store energy.

Then, the holding rod 45 is held by hand to feed the end portion of the present invention with the adhesive tape 11 roll through the movable hole 71 on the side wall of the associated packing box 70 into the packing box 70 and reach below the other end of the butt seam of the two flaps 72 along the butt seam of the two closing flaps 72. The holding rod 45 is further pushed forward horizontally, and one end of the two supporting plates 1 abuts against the inner wall of the packing box 70. Meanwhile, the pulling lever 52 is pulled, the pulling lever 52 drives the tail end of the sliding rod 49 to be separated from the limiting groove 44 on the fixed shaft A43 and the holding rod 45 is unlocked from being parallel to the roller shaft A4, and the spring C50 is further compressed to store energy. When the parallel state locking of the grip lever 45 and the roller shaft a4 is released, the grip lever 45 is horizontally swung to one side so that the two support plates 1 are swung with respect to the grip lever 45 by the inner wall of the packing box 70. When the swinging angle of the supporting plate 1 relative to the holding rod 45 reaches 90 degrees, the shift lever 52 is released, the sliding rod 49 is instantly inserted into a new limiting groove 44 under the reset action of the spring C50 and locks the vertical state of the holding rod 45 and the roller A4, and the roller 5 presses the adhesive surface of the adhesive tape 11 against the inner wall of the packaging box 70. The two folding plates 72 of the packing box 70 are continuously pressed against the inner wall of one end of the seam horizontally and vertically, and the inner wall of the packing box 70 blocks the roller 5, so that the holding rod 45 drives the sliding block A29 to slide on the supporting plate 1 in the direction of the roller shaft A4 through the fixing shaft A43, the U seat 42 and the rotating shaft B38, and the spring B35 is further stretched to store energy. The slide block A29 drives the clamp plate A22 to be quickly separated from the clamp plate B34 through a series of transmission, the clamping of the tail end of the adhesive tape 11 is released, and the two scroll springs A24 are further compressed to store energy at the same time.

The two inner rods 17 respectively extend and reset relative to the corresponding outer sleeves 15 under the reset action of the corresponding springs A19, the two inner rods 17 simultaneously drive the tensioning rollers 21 to pull the tail ends of the adhesive tapes 11, clamped by the clamping plates A22 and B34, away from the clamping plates A22 and B34 through the roller shafts C20, and the adhesive surfaces of the tail ends of the adhesive tapes 11 are pressed against the inner side wall of the packaging box 70, so that the tail ends of the adhesive tapes 11 are tightly adhered to the inner side wall of the packaging box 70.

Then, one hand presses the two closing flaps 72 of the packing box 70 downward, while the other hand lifts the holding rod 45 vertically upward, and the holding rod 45 drives the two support plates 1 and all the components mounted between the two support plates 1 to approach the inner sides of the two closing flaps 72 of the packing box 70 through a series of transmission. When the roller 5 tightly presses the adhesive surface of the adhesive tape 11 against the inner sides of the two closing flaps 72, the adhesive surface of the adhesive tape 11 is adhered to the two safety paper strips 73 on the inner sides of the two flaps 72. Meanwhile, due to the limitation of the interaction between the fixture block A40 and the fixture block B41 on the relative swinging direction of the slide block A29 and the U seat 42, the roller 5 cannot drive the slide block A29 to rotate relative to the U seat 42 through the roller shaft A4 and the two support plates 1.

The grip lever 45 is pulled back horizontally along the butt seam of the two closure flaps 72 in the packet 70 while keeping the roller 5 pressed vertically upwards towards the inside of the two flaps 72, the slide a29 is restored with respect to the support plate 1 under the restoring action of the spring B35, and the slide a29 drives the clamp a22 through a series of transmissions to again press the clamp B34.

With the horizontal pulling back of the holding rod 45 along the butt seam of the two flaps 72 of the package 70, the adhesive tape 11 on the roll of adhesive tape 11 adheres the two flaps 72, and at the same time, the adhesive tape 11 completely adheres the two security paper strips 73 on the two flaps 72, and with the adhesion of the adhesive tape 11 to the flaps 72, the roll of adhesive tape 11 rotates relative to the roller B10, and the roller 5 rotates and presses against the adhesive tape 11 adhered to the inner side of the flaps 72, so that the adhesive tape 11 can be adhered to the flaps 72 more tightly without falling off.

When the adhesive tape 11 is rolled to abut against the inner wall of the other end of the butt seam of the two folded plates 72 on the packaging box 70, the holding rod 45 is continuously pulled back, the adhesive tape 11 is rolled under the blocking of the inner wall of the packaging box 70 to drive the two supporting plates 1 and all the components mounted on the supporting plates 1 to swing around the rotating shaft B38 relative to the U seat 42, the sliding block A29 drives the clamping block B41 to be separated from the clamping block A40, and the vortex spring B37 is further compressed to store energy. With the swinging of the two support plates 1 around the rotating shaft B38, the roller 5 revolves around the rotating shaft B38 while rotating, and continuously presses the adhesive tape 11 to the inner side of the flap 72, and the adhesive tape 11 roll continuously rotates under the pulling of the adhesive tape 11.

When the roller 5 is abutted against the inner wall of the packing box 70, the adhesive tape 11 is adhered to the inner sides of the two folding plates 72 of the packing box 70, the swing rod 53 is held by a hand, the swing rod 53 swings, the swing rod 53 pulls the sliding block B57 to move in the direction parallel to the length of the supporting plate 1 through the steel wire 54, and the spring D68 is further stretched to store energy. The slider B57 drives the swing plate 62 to swing around the fixed shaft B63 through the round pin B60, and the swing plate 62 drives the blade 66 to move towards the adhesive tape 11 which is suspended and tightened between the roller 5 and the adhesive tape 11 roll through the fixed shaft C64 and the volute spring C65. When the blade 66 edge meets the tensioned tape 11, the blade 66 swings about the fixed axis C64 under the resistance of the tape 11 and continues to press the tape 11 because the blade 66 is not in a perpendicular relationship with the tape 11. When the blade 66 presses the adhesive tape 11 against the upper chopping board strip 7, the swing link 53, which continues to swing, drives the blade 66 to swing and slide on the surface of the chopping board strip 7 relative to the chopping board strip 7 through the fixed shaft C64 and the volute spring C65 under the block of the chopping board strip 7, thereby rapidly cutting off the adhesive tape 11. When the adhesive tape 11 is cut off, the acting force on the swing rod 53 is removed, the sliding block B57 is instantly reset under the reset action of the spring D68, the sliding block B57 drives the swing plate 62 to swing back and reset through the round pin B60, the blade 66 swings back and reset under the reset action of the spiral spring C65, and the sliding block B57 pulls the swing rod 53 to swing back and reset through the steel wire 54.

When the roller 5 is separated from the adhesive tape 11 adhered to the inner side of the flap 72 of the packing box 70, the holding rod 45 is pulled vertically downwards, and the holding rod 45 drives the roller 5 to tightly press and adhere the cut adhesive tape 11 to the inner wall of the packing box 70 through a series of transmission. Then, the shift lever 52 is shifted, the shift lever 52 drives the sliding rod 49 to disengage from the corresponding limiting groove 44 and release the locking of the vertical state of the holding rod 45 and the roller shaft a4, the holding rod 45 continues to be horizontally pulled back outwards, and the two support plates 1 drive all the components mounted on the support plates 1 to swing back around the fixing shaft a43 relative to the holding rod 45 under the blocking of the inner wall of the packing box 70.

When the two supporting plates 1 bring all the components mounted thereon to swing back to the initial state relative to the holding rod 45, the shift lever 52 is released, the sliding rod 49 is instantaneously reset and inserted into the other limiting groove 44 under the reset action of the spring C50, and the parallel state of the holding rod 45 and the roller shaft A4 is reset and locked. Finally, the holding bar 45 is held by hand to pull the two support plates 1 and all the components mounted on the two support plates 1 out of the packing box 70 through the movable hole 71.

In conclusion, the beneficial effects of the invention are as follows: the invention extends one end provided with the adhesive tape 11 roll into the matching movable hole 71 on the side wall of the packing box 70 and pastes and seals two sealing folded plates 72 of the packing box 70 from the inner wall of the packing box 70, so that the packing information of the packing box 70 is hidden to a certain extent, a thief is afraid to easily open the packing box 70 under the condition of uncertainty of leaving opening marks, and the safety of commodities in the packing box 70 is ensured. Meanwhile, the safety paper strips 73 on the inner side of the sealing flap 72 of the matched packing box 70 are torn when a thief opens the packing box 70, so that a receiver can judge whether the packing box 70 is opened or not by checking whether the safety paper strips 73 are intact when receiving goods, a decision of sign-off or rejection is made, and the benefit of the receiver is ensured.
