As shown in fig. 3, the diameter of the swing hole 18 is larger than that of the swing shaft 11, and the roller 25 drives the roller 28 to vibrate up and down along the sliding slot 17 at a high frequency, and at the same time, drives the whole cutting blade mechanism 13 to shake at a high frequency within the range of the swing hole 18, which is more beneficial to effectively cutting the adhesive tape 6 by the second blade 21.
The reason why the cutting edge of the second blade 21 of the present invention is serrated is to achieve higher cutting of the adhesive tape 6 placed thereon.
The L-shaped movable groove 3 provides a certain movable space for the swinging of the L-shaped rod 15 in the cutting blade mechanism 13, and the interference of the shell 1 on the swinging of the L-shaped rod 15 is avoided.
The limiting groove 4 in the invention provides a certain moving space for the U-shaped frame 14 in the cutting blade mechanism 13 to swing around the swing shaft 11, and simultaneously limits the cutting blade mechanism 13 to swing without limitation, and provides pressure for the rolling and pressing of the roller 28 along the surface of the adhesive tape 6.
In the invention, a certain gap is formed between the swing shaft 11 and the swing hole 18; when the adhesive tape 6 is adhered, one end of the adhesive tape 6 from the outlet of the adhesive tape 6 is firstly adhered to one end of the opening of the carton, the handle 16 is held to press the packaging equipment downwards, so that the roller 28 compresses the adhesive tape 6, the packaging equipment is pulled backwards horizontally, the adhesive tape 6 gradually covers the opening gap of the carton, and meanwhile, the roller 28 rolls over and compresses the adhesive tape 6 covering the opening gap of the carton, so that the adhesive tape 6 is more firmly adhered to the opening gap of the carton; in the process of adhering the adhesive tape 6, the roller 28 swings upwards around the central axis of the swing shaft 11 relative to the shell 1 and forms a certain swing angle under the action of the limiting groove 4 due to the pressing and twisting of the arm on the packaging equipment; the first scroll spring 12 deforms and stores energy; meanwhile, under the pressing action of the arm, the rolling shaft 25 drives the sliding blocks 22 at the two ends to slide upwards for a certain distance along the corresponding sliding grooves 17, and the two return springs 27 positioned on the upper end surface and the lower end surface of the sliding blocks 22 deform and store energy; the two pentagonal blocks 29 are respectively far away from the corresponding limit blocks 30 without being limited by the limit blocks 30; while pulling the packaging device backwards, the roller 28 and the two pentagonal blocks 29 synchronously rotate to apply pressure to the adhesive tape 6; when the opening gap of the carton is completely stuck, the roller 28 in the packaging equipment is also separated from the upper end surface of the carton, and under the condition that the arm continues to apply pressure, the roller 28 suddenly loses the support of the carton and moves downwards quickly; under the action of the first scroll spring 12, the cutting blade mechanism 13 swings back and forth around the swing shaft 11, due to the inertia of the cutting blade mechanism 13, the cutting blade mechanism 13 swinging back and forth around the swing shaft 11 at high frequency can swing back and forth, and the first scroll spring 12 generates reciprocating deformation for a plurality of times in a short time; repeatedly staggering the second blade 21 mounted on the L-shaped bar 15 from the first blade 10 above, to form a cut in the adhesive tape 6 located therebetween; meanwhile, under the action of the return spring 27, the two sliding blocks 22 drive the roller 28 and the two pentagonal blocks 29 to move to the initial positions on the U-shaped frame 14; under the action of the two second scroll springs 26, the roller 28 rotates in the opposite direction together with the two pentagonal blocks 29; when the two pentagonal blocks 29 on the two sides of the roller 28 move to a distance capable of interacting with the corresponding limit blocks 30, the two pentagonal blocks 29 rotating in opposite directions synchronously interact with the two limit blocks 30 respectively; the two pentagonal blocks 29 in turn drive the roller 28 and the two sliding blocks 22 to generate high-frequency vibration reciprocating up and down along the sliding grooves 17 through the rolling shafts 25; because a certain gap exists between the swing shaft 11 and the swing hole 18, the high-frequency vibration of the roller 28, the pentagonal block 29 and the two sliding blocks 22 drives the whole cutting blade mechanism 13 to vibrate up and down, the whole cutting blade mechanism 13 and the swing shaft 11 generate repeated high-frequency shaking, and the second blade 21 on the L-shaped rod 15 generates secondary high-frequency vibration, so that the adhesive tape 6 is cut more smoothly.
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 6 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 6 is fixed on the packing box, and then the roller 28 presses the adhesive tape 6 and props against the packing box; at the moment, under the pressing of an arm, the U-shaped frame 14 and the L-shaped rod 15 which are fixedly connected with each other swing around the central axis of the swing shaft 11, the roller 28 and the two pentagonal blocks 29 swing upwards for a certain extent around the swing shaft 11 along with the U-shaped frame 14 relative to the shell 1 and stop swinging under the limitation of the limiting groove 4; due to the continuous pressing of the arm, the two sliding blocks 22 arranged on the two inner sides of the two U-shaped supports 14 respectively slide upwards along the corresponding sliding grooves 17 synchronously under the driving of the roller 28 and the roller 25, the return springs 27 positioned on the upper end and the lower end of the sliding blocks 22 deform and store energy, the two pentagonal blocks 29 are far away from the limiting blocks 30 on the lower part, and the limiting blocks 30 relieve the limitation on the pentagonal blocks 29 and do not generate interaction; the second blade 21 and the bearing block 20 which are arranged on the L-shaped rod 15 swing downwards along with the L-shaped rod 15 around the swing shaft 11, and the first scroll spring 12 deforms and stores energy; the second blade 21 is gradually far away from the first blade 10 to avoid the adhesive tape 6 so as to ensure that the adhesive tape 6 is not scratched or separated by the second blade 21 with sawteeth at the edging position in the process of moving towards the outside of the transmission groove 2; then the packaging equipment is pulled again, under the action of the friction force of the upper end face of the packaging box to the roller 28, the roller 28 drives the two pentagonal blocks 29 to synchronously rotate together and roll over the adhesive tape 6 positioned below the pentagonal blocks, and the second volute springs 26 at the two ends of the roller 25 continuously deform and store energy; the adhesive tape 6 from the adhesive tape 6 gradually covers the gap of the opening of the packing box, and meanwhile, the roller 28 presses the adhesive tape 6 to enable the adhesive tape 6 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 6, the packing device is continuously pulled and kept pressed, so that the packing device drives the roller 28 to rapidly separate from the upper end face of the packing box, the support of the packing box on the roller 28 is cancelled instantly, and the two second volute spiral springs 26 enable the roller 25 to drive the roller 28 and the pentagonal block 29 to rapidly and reversely rotate; meanwhile, the two sliding blocks 22 at the two ends of the roller 25 move downwards along the corresponding sliding grooves 17 under the action of the corresponding return springs 27, and the sliding blocks 22 drive the roller 28 and the two pentagonal blocks 29 to move downwards through the roller 25; when the two pentagonal blocks 29 rotating at high speed return to the initial positions and interact with the limiting blocks 30, under the dual actions of the return springs 27 and the limiting blocks 30, the two pentagonal blocks 29 rotating at high speed drive the rollers 28 to reciprocate up and down along the sliding grooves 17 through the rolling shafts 25; because a certain gap exists between the swing shaft 11 and the swing hole 18, the two pentagonal blocks 29 and the rollers 28 which reciprocate up and down along the sliding grooves 17 drive the whole cutting blade mechanism 13 to reciprocate in the swing hole 18 at a high frequency so as to drive the second blade 21 and the bearing block 20 which are arranged on the L-shaped rod 15 to vibrate at a high frequency.
Meanwhile, the first scroll spring 12 drives the whole cutting blade mechanism 13 to swing back around the central axis of the swing shaft 11, and the second blade 21 and the bearing block 20 synchronously and rapidly swing upwards around the swing shaft 11 at the same time; when the cutting blade mechanism 13 swings back to the initial position, due to the inertia of the cutting blade mechanism 13, the cutting blade mechanism 13 continues to swing upwards around the central axis of the swing shaft 11, the first volute spiral spring 12 is reversely deformed and stores energy, the second blade 21 and the bearing block 20 respectively meet and interact with the first blade 10 and the pressing block 9 which are installed on the top surface of the transmission groove 2, the first blade 10 and the second blade 21 form first cutting on the adhesive tape 6 which is positioned between the first blade and the second blade, and the concave cambered surface at the lower end of the pressing block 9 is in contact with and extrusion with the convex cambered surface at the upper end of the bearing block 20, so that part of the adhesive tape 6 which is positioned between the pressing block 9 and the bearing block 20 is tightly adhered to the convex cambered surface of the; due to the inertia of the cutting blade mechanism 13, under the action of the first scroll spring 12, the cutting blade mechanism 13 generates reciprocating high-frequency swing for a plurality of times in a very short time, and the first blade 10 and the second blade 21 reciprocate for a plurality of times to cut the adhesive tape 6; the rotation of the two pentagonal blocks 29 drives the cutting blade mechanism 13 to shake in the swing hole 18 and the reciprocating high-frequency swing of the cutting blade mechanism 13 around the swing shaft 11, so that the first blade 10 and the second blade 21 cut the adhesive tape 6 more smoothly and quickly.
When the adhesive tape 6 is cut off by the high-frequency vibration second blade 21, the part of the adhesive tape 6 positioned between the pressing block 9 and the bearing block 20 is tightly stuck on the convex cambered surface of the bearing block 20 under the repeated mutual extrusion of the pressing block 9 and the bearing block 20 for a plurality of times, and the cutting blade mechanism 13 is reset under the action of the first scroll spring 12 and the second scroll spring 26; the tail part of the cut adhesive tape 6 positioned on the packaging box is tightly pasted at the corner of the packaging box through the rolling of the roller 28, and the head part of the adhesive tape 6 connected with the adhesive tape 6 is tightly pasted on the convex cambered surface of the bearing block 20 to prepare 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 6 is taken down from the bearing block 20 by hand, the head of the adhesive tape 6 is pulled to the outlet of the transmission groove 2, and the adhesive tape 6 is positioned below the roller 28; 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 cutting blade mechanism 13 of the invention reciprocates for a plurality of times under the action of the first scroll spring 12 to effectively cut the adhesive tape 6; meanwhile, the second volute spiral spring 26 drives the roller 28 and the two pentagonal blocks 29 to rotate at a high speed, and the two pentagonal blocks 29 rotating at the high speed respectively interact with the two limiting blocks 30 below and drive the whole cutting blade mechanism 13 to shake in the swinging hole 18, so that the vibration frequency of the cutting blade mechanism 13 is higher, and the cutting of the adhesive tape 6 is facilitated; in the process of packaging the packaging box, the packaging equipment not only realizes the covering and tight adhesion of the adhesive tape 6 to the gap of the opening of the packaging box, but also realizes the automatic cutting of the adhesive tape 6; on one hand, the equipment does not need to press the adhesive tape 6 by hands to tightly adhere to the gap of the box opening when the adhesive tape 6 covers the gap of the box opening; on the other hand, the device omits the additional pressing action when the adhesive tape 6 is cut in the traditional packaging device, so that the automatic cutting of the adhesive tape 6 is realized; the equipment 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.
