[0031] A preferred embodiment of the tension detection device of the container safety sealing strip provided by the application is shown in Figures 1 to 7 .

[0032] The tension detection device of the container safety seal strip is characterized in that two symmetrical bases 1 are arranged, an annular ring 2 is arranged at the upper end of the base 1, the annular ring 2 is fixedly connected with the base 1, a sliding groove 3 is arranged in the annular ring 2, two groups of mirror image distribution pulling mechanisms are arranged in the annular ring 2, and the pulling mechanism 6 is used for pulling the seal strip to be detected. The pulling mechanism 6 comprises a movable seat 4, the movable seat 4 is slidably arranged in the sliding groove 3, a side position seat 5 is arranged at one end of the movable seat 4, a fixing assembly 7 is arranged on the side position seat 5, the fixing assembly 7 is used for fixing the seal strip to be detected, a hydraulic rod 8 is fixedly arranged on the movable seat 4, a tension detector 9 is connected to the output end of the hydraulic rod 8, an activity block 11 is connected to the other end of the tension detector 9 through a connecting rope 10, an arc-shaped groove 12 is arranged on the side position seat 5, clamping grooves 13 are arranged on both sides of the arc-shaped groove 12, the clamping grooves 13 are arranged in an arc shape, and the activity block 11 is slidably arranged in the arc-shaped groove 12 and the clamping grooves 13.

[0033] The fixing assembly 7 comprises two symmetrical first pressing plates 14, the first pressing plates 14 are arranged on one side of the side position seat 5, two interval arranged guide rods 16 are arranged through the first pressing plates 14, one end of the guide rod 16 is fixedly connected with the side position seat 5, electric telescopic rods 17 are fixedly arranged on both sides of the side position seat 5, and the output end of the electric telescopic rod 17 is fixedly connected with the first pressing plate 14. The anti-skid pads 15 are fixedly connected with the first pressing plates 14. The tension detector 9 is divided into a tension digital display area and a tension analog display area.

[0034] The annular ring 2 is provided with two groups of symmetrical adjustment mechanisms 19, the adjustment mechanisms 19 are connected with the movable seat 4, the adjustment mechanisms 19 are used for driving the movable seat 4 to slide along the sliding groove 3 to adjust the tension direction of the seal strip. The adjustment mechanism 19 comprises a rack 18, the rack 18 is arranged in an arc shape, the curvature of the rack 18 is consistent with that of the sliding groove 3, one end of the rack 18 is fixedly connected with the movable seat 4, a support 20 is fixedly arranged on the base 1, a servo motor 21 is fixedly arranged on the support 20, a driving wheel 22 is fixedly arranged at the output shaft end of the servo motor 21, and the driving wheel 22 is engaged with the rack 18. Anti-skid pads are arranged at the bottom of the base 1.

[0035] The container safety seal strip is a key accessory for guaranteeing the safety of goods transportation, and has a unique number and an anti-fake mark. Here, the seal strip and the seal are often used interchangeably in industry terms, and both refer to a one-time safety accessory (such as high-strength plastic or metal material) of a container door lock.

[0036] In the embodiment, the tension detection device of the container safety seal strip aims to simulate the multi-directional and non-uniform tension that the seal strip may be subjected to during container transportation, so as to more accurately evaluate the performance thereof, and the working principle is as follows:

[0037] The sample of the sealing strip to be tested is placed at the fixed assembly 7 of the two sets of pulling mechanism 6. The electric telescopic rod 17 is started, and the output end of the electric telescopic rod 17 pushes the first pressing plate 14 to move along the guide rod 16 towards the sealing strip. The anti-skid pad 15 arranged on the first pressing plate 14 can increase the friction between the sealing strip, so as to ensure that the sealing strip is firmly fixed on the side seat 5 and prevents the sealing strip from slipping or falling off during the subsequent test process.

[0038] The device changes the direction of the pulling force on the sealing strip through the adjusting mechanism 19. After the servo motor 21 in the adjusting mechanism 19 is started, the output shaft drives the driving wheel 22 to rotate. Since the driving wheel 22 is engaged with the arc-shaped rack 18 fixed on the movable seat 4, when the driving wheel 22 rotates, it drives the rack 18 to move along the sliding groove 3 of the ring 2. Since the curvature of the rack 18 is consistent with that of the sliding groove 3, and the movable seat 4 is slidingly installed in the sliding groove 3, the movement of the rack 18 drives the movable seat 4 to slide in the sliding groove 3. By controlling the rotation direction and angle of the servo motor 21, the position of the movable seat 4 can be accurately adjusted, and thus the direction of the pulling force on the sealing strip is changed, simulating various different directions of the pulling force that the container may be subjected to during transportation.

[0039] When the sealing strip is fixed and the direction of the pulling force is adjusted, the hydraulic rod 8 starts to work. The output end of the hydraulic rod 8 pushes the pulling force detector 9, and the pulling force detector 9 drives the movable block 11 to slide in the arc-shaped groove 12 and the clamping groove 13 of the side seat 5 through the connecting rope 10. Since the movable block 11 is connected with the sealing strip, the pushing force of the hydraulic rod 8 is ultimately converted into the pulling force on the sealing strip, so that the sealing strip is subjected to the stretching action.

[0040] The pulling force detector 9 monitors the size of the pulling force applied to the sealing strip in real time and displays the data in the pulling force digital display and pulling force analog display areas, respectively. The operator can intuitively understand the pulling force condition of the sealing strip by observing these two display areas. With the continuous pushing of the hydraulic rod 8, the pulling force on the sealing strip gradually increases until the sealing strip breaks. During the stretching process of the sealing strip, the pulling force detector 9 records the maximum load value borne by the sealing strip. This maximum load value reflects the ultimate bearing capacity of the sealing strip under a specific direction of the pulling force and stretching condition. By repeating the above test process under different directions of the pulling force, the performance data of the sealing strip under multi-directional stress conditions can be obtained. Combined with these data, the overall performance of the container safety sealing strip can be more comprehensively and accurately evaluated, and reliable basis can be provided for the design, selection and use of the sealing strip.

[0041] Overall, the tension detection device changes the direction of the tension by adjusting the servo motor 21 in the adjusting mechanism 19, the driving wheel 22 and the rack 18, applies tension by the hydraulic rod 8 and monitors by the tension detector 9, can simulate the stress state of the sealing strip under complex working conditions, and effectively solves the problem that the test results of the existing device are inconsistent with the actual use scene.

[0042] The sealing strip sample is fixed on the side seat 5 by the fixing assembly 7, and the shape is in a straight tensile state. The tension direction is dynamically adjusted by the adjusting mechanism 19, the servo motor 21 drives the driving wheel 22, drives the rack 18 and the movable seat 4 to slide along the sliding groove 3, so as to change the tension angle, such as Figure 1 The mechanism is shown. The stress state is simulated in multiple directions, the tension detector 9 is pushed by the hydraulic rod 8, the tension is applied by the connecting rope 10 and the movable block 11, the movable block 11 slides in the arc-shaped groove 12 and the clamping groove 13, and the non-uniform stress simulation is realized.

[0043] The application expands the standard: the tension detector 9 is provided with a "tension digital display and tension analog display area", which displays the tension data in real time. During testing, the maximum load value, tensile strength and elongation at break under multiple directions are recorded and compared with the industry standard. Through repeated testing under different tension directions, the performance data of the sealing strip under multiple direction stress conditions can be obtained, which provides a basis for overall performance evaluation.

[0044] Since the fixing assembly 7 includes the first pressing plate 14, the guide rod 16 and the electric telescopic rod 17. The electric telescopic rod 17 pushes the first pressing plate 14 to move along the guide rod 16, and the friction force is increased by combining the anti-skid pad 15. In addition, the two ends of the sealing strip are fixed by two groups of pulling mechanisms 6 synchronously, so as to ensure balanced stress.

[0045] In further preferred embodiments of the application:

[0046] The support frame 23 is fixedly installed on the annular ring 2, and the pressing mechanism 24 is arranged on the support frame 23. The pressing mechanism 24 is used for applying pressure to the sealing strip. The pressing mechanism 24 comprises a circular ring 25 rotatably installed on the support frame 23, an inner plate 26 fixedly installed in the circular ring 25, the inner plate 26 being hollow inside, two second pressing plates 27 spaced apart and arranged in the circular ring 25, two circular rods 28 fixedly installed in the inner plate 26 and spaced apart, the circular rods 28 penetrating through the second pressing plates 27, and the second pressing plates 27 being slidably installed on the circular rods 28.

[0047] Two second pressing plates 27 are rotatably installed on the inner plate 26, one end of each of the second pressing plates 27 is fixedly installed with an eccentric wheel 30, the other end of each of the second pressing plates 27 is fixedly installed with a transmission wheel 31, a stepping motor 32 is fixedly installed on the inner plate 26, and an output shaft of the stepping motor 32 is fixedly connected with one side of the second pressing plate 27.

[0048] In the embodiment, the circular ring 25 is rotatably installed on the support frame 23, and the inner plate 26 is fixedly installed in the circular ring 25. The two second pressing plates 27 are arranged at intervals in the circular ring 25, and the two circular rods 28 are fixedly installed at intervals in the inner plate 26. The circular rods 28 penetrate through the second pressing plates 27, and the second pressing plates 27 are slidably installed on the circular rods 28. This structure enables the second pressing plates 27 to slide on the circular rods 28, providing a movement basis for subsequent pressing actions.

[0049] The two rotating shafts 29 are rotatably installed on the inner plate 26 at intervals, and the eccentric wheel 30 is fixedly installed at one end of each rotating shaft 29, and the transmission wheel 31 is fixedly installed at the other end of each rotating shaft 29. The stepping motor 32 is fixedly installed on the inner plate 26, and the output shaft of the stepping motor 32 is fixedly connected with one of the rotating shafts 29. The stepping motor 32 serves as a power source to provide driving force for the entire pressing mechanism 24.

[0050] When it is necessary to apply pressure to the sealing strip, the stepping motor 32 is started. The output shaft of the stepping motor 32 rotates to drive the rotating shafts 29 to rotate. Since the two rotating shafts 29 are connected through the transmission wheel 31 (which may be a gear transmission, a belt transmission, etc., although it is not explicitly stated, but it can be reasonably inferred that there is a transmission relationship), the rotation of one rotating shaft 29 will drive the other rotating shaft 29 to rotate synchronously.

[0051] When the rotating shafts 29 rotate, the eccentric wheels 30 fixedly installed at one end of the rotating shafts 29 also rotate. The special structure of the eccentric wheels 30 causes the distance from the outer edge to the center of the rotating shaft 29 to change constantly during rotation. When the eccentric wheels 30 rotate, the outer edge will contact the second pressing plates 27 and push the second pressing plates 27. Under the pushing of the eccentric wheels 30, the second pressing plates 27 slide along the circular rods 28 and gradually approach the sealing strip. With the continuous rotation of the eccentric wheels 30, the pressure applied by the second pressing plates 27 to the sealing strip gradually increases, thereby realizing the pressing operation of the sealing strip. By controlling the rotation direction and angle of the stepping motor 32, the position of the eccentric wheels 30 can be accurately adjusted, and thus the size and duration of the pressure applied by the second pressing plates 27 to the sealing strip can be controlled.

[0052] When the required pressure value or pressing time is reached, the stepping motor 32 is stopped, and the eccentric wheels 30 stop rotating. Under the action of its own gravity or other reset mechanisms (if any), the second pressing plates 27 may gradually move away from the sealing strip, and the pressing process ends.

[0053] In summary, the pressing mechanism drives the rotating shaft 29 and the eccentric wheel 30 to rotate through the stepping motor 32, pushes the second pressing plate 27 to apply pressure to the sealing strip by the structural characteristics of the eccentric wheel 30, can simulate the pressure condition that the sealing strip may be subjected to in actual use, further enriches the test means for the performance of the sealing strip, and makes the test result more comprehensive and accurate. The stepping motor 32 accurately adjusts the position of the eccentric wheel 30 by controlling the rotating angle, and indirectly controls the pressure size. It is stated in the part of the invention content that the position of the eccentric wheel 30 can be accurately adjusted by controlling the rotating direction and angle of the stepping motor 32, and then the size and duration of the pressure applied by the second pressing plate 27 to the sealing strip are controlled.
