S300: if the length of the sensing rod 330 is not changed, the bonding performance of the connecting part of the packing boxes is good.
S400: if the length of any one of the sensing rods 330 is changed, the position where the length of the sensing rod 330 is changed is the air leakage point at the joint of the packaging box.
In combination with the above embodiments, the working process of the system for detecting the bonding strength of the paperboard packaging box provided by the embodiment of the application is as follows:
during operation, to-be-detected packing box is placed on the locating plate 120, the first clamping block 130 is moved, the first clamping block 130 pushes the packing box to move on the locating plate 120, meanwhile, the driving rod 141 on the second clamping block 140 is rotated, the second clamping block 140 and the first clamping block 130 are used for jointly locating the packing box, the packing box is gradually moved to a preset position, at the moment, one side wall of the packing box is abutted against the first side wall of the detecting block 310, one side wall of the packing box is abutted against the second side wall of the detecting block 310, at the moment, the connecting position of the packing box is abutted against the first side wall of the detecting block 310, and the limiting pin 131 on the first clamping block 130 is controlled to be inserted into the locating hole 121.
Starting the driving cylinder 150, the driving cylinder 150 starts to extend, the extending end of the driving cylinder 150 pushes the driving block 220 to gradually slide downwards along the supporting rod 112, the sealing film 210 arranged on the driving block 220 gradually approaches to the opening of the packaging box, meanwhile, the two tightening blocks 510 arranged on the driving block 220 gradually shorten, the widths of the two tightening blocks 510 synchronously change, the sliding part 512 of one tightening block 510 abuts one side wall of the packaging box against the first side wall of the detecting block 310, and the sliding part 512 of the other tightening block 510 abuts the other side wall of the packaging box against the second side wall of the detecting block 310. After the sealing film 210 contacts the opening of the packaging box, the driving cylinder 150 is closed, the driving motor 230 is started, the driving motor 230 drives the eccentric wheel 240 to rotate, the eccentric wheel 240 pulls the sealing film 210 to deform through the traction rope 250, when the sealing film 210 is upwards lifted, the air pressure in the packaging box is reduced, the first one-way valve is conducted, air enters the packaging box through the first one-way valve, and along with the continuous rotation of the eccentric wheel 240, the eccentric wheel 240 rotates 180 degrees, then the driving motor 230 is stopped, the eccentric wheel 240 does not pull the sealing film 210 through the traction rope 250 any more, the sealing film 210 is gradually and automatically reset, and the air pressure in the packaging box is gradually increased.
If the bonding portion of the packing case is sealed well, the high pressure gas in the packing case passes through the sealing film 210 again through the second check valve. If there is a gap at the bonding position of the packaging box, the high-pressure gas in the packaging box enters a certain detection cavity 312 through the gap and then enters the detection cavity 312 to push the induction rod 330 to stretch through the gas guide pipe, because the induction rod 330 and the unlocking rod 420 are in butt joint in the initial state, when the induction rod 330 stretches, the unlocking rod 420 gradually slides along the guide groove and gradually moves away from the reaction rod 320, the induction rod 330 drives the blocking block 410 to rotate through the first transmission rod 430, the blocking block 410 is released from the blocking of the baffle 311 in the second section, at this moment, the detection block 310 is slowly shortened under the action of the tension spring 350 and the damping cylinder 340, and because the distance detector is arranged on the detection block 310, the distance detector can acquire the distance between the upper end and the lower end of the detection block 310, when the detection block 310 is shortened, the signal of the distance detector is transmitted to the control panel, and the control panel controls the all conduction of the plurality of air release valves 370 according to the signal of the distance detector, so that the gas in the detection cavity 312 can be timely discharged when the detection block 310 is shortened.
When the length of one of the sensing rods 330 is changed, the limiting rods connected to the sensing rod 330 with the changed length simultaneously enter the limiting grooves. In the shortening process of the detection block 310, the control rods 360 at two ends of the detection block 310 gradually approach each other until the two control rods 360 enter the limiting grooves, at this time, the length of the detection block 310 in the vertical direction is equal to the thickness of one original detection cavity 312, and when the detection block 310 is shortened to the thickness of one original detection cavity 312, the control board controls the plurality of air release valves 370 to be fully blocked according to signals of the distance detector.
Starting the driving motor 230, the driving motor 230 drives the eccentric wheel 240 to rotate 180 degrees again, and then the eccentric wheel 240 pulls the sealing film 210 to deform through the traction rope 250, so that the air pressure in the packaging box is gradually increased, and at the moment, the high-pressure air in the packaging box enters one or more detection cavities 312 again, and the specific position of air leakage at the joint of the packaging box is further refined according to the length change of the sensing rod 330 corresponding to the detection cavity 312, so that the reprocessing treatment of the air leakage packaging box is facilitated, and the manufacturing efficiency of the packaging box is improved. The driving cylinder 150 is then controlled to be shortened and the stretch detecting block 310 is extended to an initial state, and all the sensing rods 330 are pushed to an initial length and the unlocking rod 420 is pushed to be restored to an initial position.
The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the application.
