The working process of the invention is as follows: when the opening of the packing box is packaged, firstly, the head of the adhesive tape 8 is pulled by hands to be adhered to the corner of the opening of the packing box, so that one end of the adhesive tape 8 is fixed on the packing box, and then the roller 30 presses the adhesive tape 8 and props against the packing box; at the moment, under the pressing of an arm, the U-shaped frame 23 and the L-shaped rod 21 which are fixedly connected with each other swing around the central axis of the swing shaft 34, the roller 30 and the two eccentric wheels 31 swing upwards for a certain extent around the swing shaft 34 along with the U-shaped frame 23 relative to the shell 1 and stop swinging under the limitation of the swing limiting groove 6; the second blade 29 and the bearing block 28 which are arranged on the L-shaped rod 21 swing downwards along with the L-shaped rod 21 around the swing shaft 34, the L-shaped rod 21 drives the gear 12 to rotate through the second arc-shaped rack 27 arranged on the side surface of the L-shaped rod, the gear 12 drives the first blade 19 and the pressing block 18 which are arranged on the lower end surface of the supporting block 17 to swing upwards around the swing shaft 34 through the first arc-shaped rack 15 meshed with the gear 12, and the first volute spiral spring 22 deforms and stores energy; the first blade 19 and the second blade 29 are far away from each other to avoid the adhesive tape 8 so as to ensure that the adhesive tape 8 is not scratched or cut by the first blade 19 and the second blade 29 during the movement towards the outside of the transmission groove 2; then the packaging device is pulled again, under the action of the friction force of the upper end face of the packaging box to the roller 30, the roller 30 drives the two eccentric wheels 31 to synchronously rotate together and roll the adhesive tape 8 below the eccentric wheels, and the second volute springs 33 at the two ends of the rolling shaft 32 continuously deform and store energy; the adhesive tape 8 from the adhesive tape 8 roll gradually covers the gap of the opening of the packing box, and meanwhile, the roller 30 presses the adhesive tape 8 to enable the adhesive tape 8 to be tightly attached to the packing box and firmly adhered to the gap of the opening of the packing box; when the gap at the mouth of the packing box is completely adhered by the adhesive tape 8, the packing device is continuously pulled and pressed, so that the packing device drives the roller 30 to be quickly separated from the upper end surface of the packing box, the support of the packing box on the roller 30 is instantly cancelled, and the roller 32 drives the roller 30 and the eccentric wheel 31 to quickly and reversely rotate by the two second volute springs 33; the high speed counter rotation of the two eccentrics 31 causes the entire lower blade mechanism 20 to rock in the pendulum hole 25, which in turn causes the second blade 29 to oscillate at high frequency.
Meanwhile, the first scroll spring 22 drives the whole lower blade mechanism 20 to swing back around the central axis of the swing shaft 34, the second blade 29 and the supporting block 28 synchronously swing upwards around the swing shaft 34, the second arc-shaped rack 27 arranged on the side surface of the L-shaped rod 21 drives the first arc-shaped rack 15 to move downwards along the arc-shaped trapezoidal guide groove 5 through the gear 12 meshed with the second arc-shaped rack, and the first arc-shaped rack 15 drives the first blade 19 and the pressing block 18 to quickly swing downwards around the central axis of the swing shaft 34 through the supporting block 17; when the lower blade mechanism 20 and the upper blade mechanism 14 swing back to the initial positions, due to the inertia of the lower blade mechanism 20, the lower blade mechanism 20 continues to swing upwards around the central axis of the swing shaft 34, the first volute spiral spring 22 deforms reversely and stores energy, the second arc-shaped rack 27 arranged on the side surface of the L-shaped rod 21 drives the first arc-shaped rack 15 to continue to slide downwards along the arc-shaped trapezoidal guide groove 5 through the gear 12, the first arc-shaped rack 15 drives the first blade 19 and the pressing block 18 to continue to swing downwards around the swing shaft 34 through the supporting block 17 and interact with the second blade 29 and the supporting block 28 which continue to swing upwards around the swing shaft 34 respectively, the first blade 19 and the second blade 29 which move towards each other form a first cutting to the adhesive tape 8 positioned between the first blade and the second blade 29, and the concave arc surface at the lower end of the pressing block 18 is in contact with and is pressed to the convex arc surface at the upper end of the supporting block 28, so that the part of the adhesive tape 8 positioned between the pressing block 18 and the bearing block 28 is tightly stuck on the convex cambered surface of the bearing block 28; due to the inertia of the lower blade mechanism 20, under the action of the first scroll spring 22, the lower blade mechanism 20 and the upper blade mechanism 14 generate reciprocating high-frequency opposite or back-to-back swing for a plurality of times in a very short time, and the first blade 19 and the second blade 29 reciprocate for a plurality of times to cut the adhesive tape 8; the rotation of the two eccentric wheels 31 drives the lower blade mechanism 20 to swing in the swing hole 25, and the lower blade mechanism 20 and the upper blade mechanism 14 swing around the swing shaft 34 in a reciprocating high-frequency mode, so that the first blade 19 and the second blade 29 cut the adhesive tape 8 more smoothly and quickly.
When the adhesive tape 8 is cut off by the first blade 19 and the second blade 29 which vibrate at high frequency, the part of the adhesive tape 8 positioned between the pressing block 18 and the bearing block 28 is tightly stuck on the convex cambered surface of the bearing block 28 under the repeated mutual extrusion of the pressing block 18 and the bearing block 28 for a plurality of times, and the upper blade mechanism 14 and the lower blade mechanism 20 are reset under the action of the first spiral spring 22 and the second spiral spring 33; the tail part of the cut adhesive tape 8 positioned on the packaging box is tightly pasted at the corner of the packaging box through the rolling of the roller 30, the head part of the adhesive tape 8 connected with the adhesive tape 8 roll is tightly pasted on the convex cambered surface on the bearing block 28, and the preparation is made for pasting the opening of the packaging box next time; when another packaging box needs to be continuously pasted, the head of the adhesive tape 8 is taken down from the bearing block 28 by hand, the head of the adhesive tape 8 is pulled to the outlet of the transmission groove 2, and the adhesive tape 8 is positioned below the roller 30; repeating the above actions to complete the packaging of the opening of the packaging box.
In conclusion, the invention has the beneficial effects that: the upper blade mechanism 14 and the lower blade mechanism 20 in the invention can do reciprocating swing for a plurality of times under the action of the first scroll spring 22, and the adhesive tape 8 can be effectively cut; meanwhile, the second volute spiral spring 33 drives the roller 30 and the two eccentric wheels 31 to rotate at a high speed, and the two eccentric wheels 31 rotating at the high speed drive the whole lower blade mechanism 20 to shake in the swing hole 25, so that the vibration frequency of the lower blade mechanism 20 is higher, and the adhesive tape 8 can be cut more conveniently; in the process of packaging the packaging box, the packaging device not only realizes the covering and tight adhesion of the adhesive tape 8 to the gap of the opening of the packaging box, but also realizes the automatic cutting of the adhesive tape 8; on one hand, the device does not need to press the adhesive tape 8 by hands to tightly adhere to the gap of the box opening when the adhesive tape 8 covers the gap of the box opening; on the other hand, the device omits the additional pressing action when the adhesive tape 8 is cut in the traditional packaging device, so that the automatic cutting of the adhesive tape 8 is realized; the device greatly saves the physical power of workers who pack and package the box opening of the packing box in batches, and effectively improves the working efficiency of the workers.
