And a mounting rack 51 is arranged on the telescopic slide rail 50 in a sliding manner, and the mounting rack 51 is used as a mounting platform for each element of the ton bag detection device. A first lead screw motor 52 is arranged between the detection frame 5 and the mounting frame 51, and the mounting frame 51 can be pushed to perform linear displacement under the limiting of the telescopic slide rail 50 through the action of the first lead screw motor 52. A central cylinder 53 is arranged in the middle of the mounting frame 51, and an insertion cylinder 54 is arranged in the central cylinder 53 in a sliding manner. The insertion cartridge 54 is used for insertion into a ton bag for strength testing. Specifically, four long grooves are uniformly formed in the circumference of the bottom of the insertion cylinder 54, a connecting rod 55 is hinged in each long groove, the front end of the connecting rod 55 is located in the insertion cylinder 54, the tail end of the connecting rod 55 is hinged to a push plate 56, in order to ensure that the push plate 56 is always in a vertical state in the embodiment, the tail end of the connecting rod 55 is connected with the middle of the push plate 56, and the bottom of the push plate 56 is provided with a balance weight. The second lead screw motor 57 is installed on the top of the insertion tube 54, and the second lead screw motor 57 is used for pushing the insertion tube 54 to move along the vertical direction of the central tube 53, so that the operation of inserting the insertion tube into the ton bag for strength detection is realized. A first pressure sensor is installed between the second lead screw motor 57 and the insertion cylinder 54. A push rod 58 is slidably installed in the insertion cylinder 54, the bottom of the push rod 58 is in contact with the front ends of the four connecting rods 55, and the connecting rods 55 can be shifted from the vertical state to the horizontal state by pushing the push rod 58. When the push rod 58 is out of contact with the front end of the link 55, the link 55 returns to a nearly vertical position under the action of gravity. A third lead screw motor 59 is arranged at the top of the push rod 58, and a second pressure sensor is arranged between the push rod 58 and the third lead screw motor 59.

The second lead screw motor 57 is used for pushing the insertion cylinder 54 to slide into the ton bag, when the bottom of the insertion cylinder 54 contacts the bottom surface of the ton bag, the first pressure sensor starts to measure a numerical value, and when the pressure exceeds a preset numerical value, the ton bag is proved to meet the longitudinal strength requirement. The first screw motor 52, the second screw motor 57 and the third screw motor 59 are all servo motors, and the mounting frame 51, the insertion tube 54 and the push rod 58 can be precisely displaced under the control of the control system.

Specifically, the two sides of the top of the hoisting frame 32 are provided with slots 34, and the slots 34 are T-shaped slots. Bosses corresponding to the slots 34 are arranged on two sides of the bottom of the mounting frame 51 and are in sliding fit with the slots 34. After the hoisting wheel set 42 triggers the detection sensor, the control system receives the signal and controls the hoisting line 1 to stop running, and the hoisting frame 32 stops at the position butted with the mounting frame 51. Subsequently, the control system controls the first lead screw motor 52 to move to push out the mounting frame 51, the boss on the mounting frame 51 is butted with the slot 34, so that the mounting frame 51 and the hoisting frame 32 are relatively fixed, and most of pressure is borne by the mounting frame 51 during intensity detection, so that the hoisting line 1 is prevented from being damaged.

More specifically, hang that the sensor is the front and back order and linearly set up N, hoist wheelset 42 circulates through the position of hanging with 1-N order, and N when hanging the sensor and being triggered by same hoist wheelset 42 in proper order, only arrange the position and hang wheelset 42 and pass through the triggering of the unanimous sensor that hangs of order and make the transfer chain pause for effective triggering. That is, after the hoisting line 1 is started, after the first passing hoisting frame 32 triggers all suspension sensors, only the signal of the first triggered suspension sensor is received by the control system to control the hoisting line to stop running, and the hoisting frame 32 is stopped at the first suspension sensor, and after the second passing hoisting frame 32 triggers all suspension sensors, only the signal of the second triggered suspension sensor is received by the control system to control the hoisting line to stop running, and the hoisting frame 32 is stopped at the second suspension sensor.

Taking the example of installing 3 hoisting frames 32 on the hoisting line 1, which means that the hoisting line 1 runs for a week, 3 ton bags are sampled and inspected. When the hoisting line 1 is operated, according to the time sequence, the operation programs of the components are as follows: the hoisting cable 3 circularly runs under the driving of the driving motor 25, when the hoisting wheel set 42 triggers the suspension sensor at the suspension position, the suspension sensor transmits the model to the control system, the control system controls the driving motor 25 to stop, and at the moment, a worker must suspend the next ton of bags at the bottom of the hoisting frame 32 and think that the hoisting line 1 is started. When the hoisting frame 32 reaches the detection position through the conveying of the hoisting line 1 to trigger the detection sensor, the control system controls the driving motor 25 to stop acting, controls the first lead screw motor 52 to extend, pushes out the mounting frame 51 to enable the mounting frame to be in butt joint with the hoisting frame 32, and at the moment, the insertion cylinder 54 is just above the top opening of the ton bag. The control system then controls the second lead screw motor 57 to extend, inserting the insertion cartridge inside the ton bag, and then the control system controls the third lead screw motor 59 to extend, so that the push rod 58 drives the link 55 to shift from the vertical state to the horizontal state until the push plate 56 contacts the inner wall of the ton bag. When the value detected by the second pressure sensor exceeds the set value, the transverse strength of the ton bag is proved to meet the requirement. Then the control system controls the third lead screw motor 59 to retract a certain distance, so that the push plate 56 loosens the support on the inner part of the ton bag, then controls the second lead screw motor 57 to continue to extend a certain distance, reselects the detection position in the ton bag, and then controls the third lead screw motor 59 to extend, so that the push rod 58 drives the connecting rod 55 to shift from the vertical state to the horizontal state until the push plate 56 is contacted with the inner wall of the ton bag, and the strength detection at the position is completed. When the transverse strength of the ton bag is detected, 2-4 positions are selected in the height direction of the ton bag for detection. Finally, after the multi-point transverse strength detection is completed, the control system controls the second lead screw motor 57 to continuously push the insertion tube 54 to extend towards the inside of the ton bag until the bottom of the insertion tube 54 contacts the bottom surface of the ton bag, at the moment, the connecting rod 55 drives the push plate 56 to relatively open to prop open the inner wall of the ton bag for a certain space, the bottom of the insertion tube 54 is tightly propped against the ton bag along with the pushing of the second lead screw motor 57, four handles of the ton bag are stretched straight, after the value of the first pressure sensor reaches a set value, the marking of the vertical strength of the ton bag is proved, the controller controls the third lead screw motor 59 to reset, the connecting rod 55 is driven by the push rod 58 to be in a relatively vertical state, the second lead screw motor 57 resets to drive the insertion tube 54 to slide out of the ton bag, the first lead screw motor 52 resets to drive the mounting frame 51 to be separated from the butt joint with the lifting frame 32. And then the control system controls the hoisting line 1 to be started continuously, and the unloading, folding and packaging work of the ton bags can be finished continuously by the packaging position.

More specifically, the detection sensor of the detection position has a higher priority than the suspension sensor of the suspension position, and when the detection sensor is triggered to stop the operation of the suspension line 1, the suspension line cannot be restarted at the suspension position by stepping on the on-off switch.

More specifically, the device is provided with a paint spraying mechanism 6 for spraying the ton bag at the detection position. When the detected ton bag does not meet the requirements on transverse strength or vertical strength, the control system controls the air injection mechanism 6 to start, the unqualified ton bag is marked, and the packaging position is convenient to separate.

When the sampling inspection is carried out, after the sampling inspection unqualified products of the ton bags on the same day exceed 5 pieces, all the ton bags need to be inspected completely.
