Description

Technical Field

[0001] This invention relates to the field of packaging barrel testing technology, and in particular to a packaging barrel testing system and testing method. Background Technology

[0002] To ensure the safety of hazardous chemical packaging containers during transportation, performance testing of the containers is necessary to guarantee that hazardous chemicals will not leak during transport.

[0003] In the prior art, Chinese patent document CN118730731B, published on October 1, 2024, discloses a quality inspection device for plastic bucket production. This device includes a base plate with an extrusion assembly, an auxiliary assembly, and two conveying assemblies. The extrusion assembly allows for rapid adjustment and fixation of the plastic bucket's position on a supporting circular plate, significantly improving the bucket clamping speed. Furthermore, the large range of motion of the extrusion rod allows for the inspection of plastic buckets of various sizes. The extrusion and auxiliary assemblies enable airtightness testing of the plastic buckets via an air pump and strength testing by pressing the circular plate and extrusion rod. The coordinated operation of the extrusion, auxiliary, and conveying assemblies allows for rapid quality inspection of the plastic buckets and the sorting and conveying of the inspected buckets. However, the inspection only tests empty plastic buckets, without filling them with liquid, thus failing to provide information on the actual performance of the plastic buckets in use, presenting significant limitations.

[0020] Used for airtightness testing, hydraulic testing, drop testing, and stacking testing of packaging drums; among them...

[0021] During the airtightness test, the packaging barrel is transported to the bottom of the airtightness testing mechanism through the conveying unit. The airtightness testing mechanism introduces air pressure of 15~25kPa into the packaging barrel and observes the change of the pressure gauge reading on the airtightness testing mechanism to determine whether the airtightness of the packaging barrel is qualified.

[0022] During the hydraulic test, the packaging barrel is transported to the rotary conveyor weighing platform by the first conveying device of the conveying unit. Ultrapure water is injected into the packaging barrel through the liquid injection mechanism. When the injected weight reaches the set weight, the packaging barrel is transported to the bottom of the hydraulic testing mechanism by the conveying unit. Then, the hydraulic testing mechanism introduces air pressure of 150~250kPa into the packaging barrel and observes the change of the pressure gauge reading on the hydraulic testing mechanism to determine whether the hydraulic test of the packaging barrel is qualified.

[0023] During the drop test, the packaging drum is transported to the rotary conveyor weighing platform via the first conveying device of the conveying unit. Antifreeze is injected into the packaging drum through the injection mechanism. Once the injected weight reaches the set weight, the drum cap is screwed on. The packaging drum is then transported between the drop test mechanism and the stacking test mechanism via the conveying unit. The drop test mechanism moves to the side of the packaging drum via the moving unit, clamps the packaging drum, and moves it to the drop test area. The cooling unit lowers the temperature of the drop test area to -15℃ to -20℃. The drop test mechanism clamps the packaging drum, lifts it to a certain height, and then opens it. The packaging drum falls freely and impacts the ground. The drop test is judged based on the leakage of the packaging drum.

[0024] During the stacking test, the packaging drum is transported to the rotary conveyor weighing platform via the first conveying device of the conveying unit. Ultrapure water is injected into the packaging drum through the liquid injection mechanism. Once the injected weight reaches the set weight, the drum cap is screwed on. The packaging drum is then transported between the drop test mechanism and the stacking test mechanism via the conveying unit. The drop test mechanism moves to the side of the packaging drum via the moving unit, clamps the packaging drum, and moves it to the stacking test area. The heating unit raises the temperature of the stacking test area to 35℃~45℃. The stacking test mechanism places weights on top of the packaging drum and maintains this temperature for 15~35 days. The stacking test is judged to be qualified based on the deformation and leakage of the packaging drum.

[0025] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art:

[0026] The test chamber of this invention provides an enclosed space for installing a track unit. The track unit suspends five movable units, which are distributed to move or adjust the positions of a liquid injection mechanism, an airtightness detection mechanism, a hydraulic testing mechanism, a drop testing mechanism, and a stacking testing mechanism. The liquid injection mechanism is used to inject liquid into the packaging barrel. The airtightness detection mechanism is used to detect the airtightness of the packaging barrel. The hydraulic testing mechanism is used to detect leakage under pressure after the packaging barrel is injected with liquid. The drop testing mechanism is used to detect leakage after the packaging barrel is dropped after being injected with liquid. The stacking testing mechanism is used to detect deformation and leakage after the packaging barrel is stacked after being injected with liquid. A rotary conveyor weighing platform is used to convey the packaging barrel and weigh it when the liquid is injected into the packaging barrel. Then, by rotating, the packaging barrel is aligned with the first conveying device in each direction. The first conveying device is used to convey the packaging barrel to each testing area. This invention can perform airtightness testing, hydraulic testing, drop testing, and stacking testing on packaging barrels through an airtightness testing mechanism, a hydraulic testing mechanism, a drop testing mechanism, and a stacking testing mechanism. It can also inject liquid into the packaging barrels through a liquid injection mechanism, thereby testing the hydraulic, drop, and stacking performance of the packaging barrels in actual use.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic.

[0054] Example 1:

[0055] See Figure 1-12 A packaging barrel testing system includes a test chamber 10, with an opening and closing door 11 on one side. A track unit 20 is installed on the top of the test chamber 10, and five moving units 40 are suspended on the track unit 20. A liquid injection mechanism 50, an airtightness testing mechanism 60, a hydraulic testing mechanism 70, a drop testing mechanism 80, and a stacking testing mechanism 90 are respectively installed at the lower ends of the five moving units 40. A conveying unit 100 is also installed at the bottom of the test chamber 10. The conveying unit 100 includes a rotary conveying weighing platform 110, and multiple first conveying devices 120 are arranged around the rotary conveying weighing platform 110 for conveying and transferring the packaging barrels 1. The system also includes a cooling unit 12 and a heating unit 16 for cooling and heating the test chamber 10.

[0056] The test chamber 10 adopts a heat-insulating structure and provides a relatively enclosed space for testing. The top of the test chamber 10 is equipped with a track unit 20, which is used to suspend and install five moving units 40. The five moving units 40 are used to move or adjust the positions of the liquid injection mechanism 50, the air tightness testing mechanism 60, the hydraulic testing mechanism 70, the drop testing mechanism 80, and the stacking testing mechanism 90. The liquid injection mechanism 50 is used to inject liquid into the packaging barrel 1. The air tightness testing mechanism 60 is used to test the air tightness of the packaging barrel 1. The hydraulic testing mechanism 70 is used to test the leakage of the packaging barrel 1 under pressure after liquid injection. The drop testing mechanism 80 is used to test the leakage of the packaging barrel 1 after it is dropped after liquid injection. The stacking testing mechanism 90 is used to test the deformation and leakage of the packaging barrel 1 after it is stacked after liquid injection. The rotating conveying weighing platform 110 is used to transport the packaging barrel 1 and weigh it when liquid is injected into the packaging barrel 1. Then, by rotating, the packaging barrel 1 is aligned with the first conveying device 120 in each direction. The first conveying device 120 is used to transport the packaging barrel 1 to each testing area. In this embodiment, the first conveying device 120 can be a roller conveyor or a belt conveyor. With the above structure, the present invention can perform airtightness testing, hydraulic testing, drop testing, and stacking testing on the packaging drum 1 through the airtightness testing mechanism 60, the hydraulic testing mechanism 70, the drop testing mechanism 80, and the stacking testing mechanism 90. Furthermore, the packaging drum 1 can be injected with liquid through the liquid injection mechanism 50, thereby enabling testing of the hydraulic, drop, and stacking performance of the packaging drum 1 during actual use.

[0057] For ease of observation, an observation window 13 can also be installed on the test chamber 10. The opening and closing door can be an insulated sliding door as used in existing technologies.

[0058] See Figure 1The track unit 20 includes a first track segment 21, a second track segment 22, a third track segment 23, and a fourth track segment 24. The first track segment 21 is vertically installed on the middle of one side of the fourth track segment 24. The first track segment 21 is located on one side of the opening and closing door 11 and is directly opposite to the opening and closing door 11. The second track segment 22 and the third track segment 23 are vertically and symmetrically installed on both sides of the middle of the first track segment 21. One moving unit 40 is suspended on the first track segment 21, the second track segment 22, and the third track segment 23, respectively. Two moving units 40 are suspended on the fourth track segment 24. The lower end of the moving unit 40 on the first track segment 21 is equipped with a liquid injection mechanism 50. The lower end of the moving unit 40 on the second track segment 22 is equipped with a hydraulic testing mechanism 70. The lower end of the moving unit 40 on the third track segment 23 is equipped with an airtightness testing mechanism 60. The lower ends of the two moving units 40 on the fourth track segment 24 are equipped with a drop testing mechanism 80 and a stacking testing mechanism 90, respectively. In order to facilitate the transport of the packaging barrel 1 to the transport unit 100 of the test chamber 10, a first transport device 120 is provided on the inner side of the opening and closing door 11, and a second transport device 130 is provided on the outer side of the opening and closing door 11. Both the first transport device 120 and the second transport device 130 can be belt conveyors or roller conveyors.

[0059] Furthermore, four first conveying devices 120 are arranged in a cross shape around the rotary conveying weighing platform 110. The center of the rotary conveying weighing platform 110 is located at the intersection of the central axes of the first track section 21 and the second track section 22. The four first conveying devices 120 are located directly below the first track section 21, the second track section 22 and the third track section 23.

[0060] By arranging four first conveying devices 120 in a cross shape around the rotary conveyor weighing platform 110, which is located directly below the liquid injection mechanism 50, and cooperating with the upper track unit 20, the packaging barrels 1 entering the rotary conveyor weighing platform 110 can be conveyed to the corresponding testing areas. Since the conveying units 100 are arranged in a cross shape, the drop test mechanism 80 and the stacking test mechanism 90 are located on either side of one of the first conveying devices 120. Utilizing the clamping function of the drop test mechanism 80, the packaging barrels 1 located on the first conveying device 120 between the drop test mechanism 80 and the stacking test mechanism 90 can be clamped and moved to the drop test area, and also to the stacking test area, thus simplifying the structure of the conveying unit 100.

[0061] See Figure 4 , 5The track unit 20 includes two C-shaped rails with their grooves facing each other. The moving unit 40 includes a suspension seat 41 with at least two horizontal shafts 42 mounted on it. Suspension wheels 43 are rotatably mounted on both sides of the horizontal shafts 42. The suspension wheels 43 are placed in the grooves of the two C-shaped rails. A through hole 411 is provided in the middle of the suspension seat 41. A first reduction motor 44 is installed in the through hole 411. A first gear 45 is installed on the output shaft of the first reduction motor 44. The first gear 45 meshes with a rack 46. The rack 46 is fixedly installed on the lower side of the C-shaped rail. A suspension plate 47 is fixedly installed on the lower side of the suspension seat 41. The lower side of the suspension plate 47 of the five moving units 40 is used to install a liquid injection mechanism 50, an airtightness detection mechanism 60, a hydraulic testing mechanism 70, a drop testing mechanism 80, and a stacking testing mechanism 90, respectively. With the above structure, when the first geared motor 44 is driven, it drives the first gear 45 to rotate. Since the first gear 45 meshes with the rack 46, it drives the suspension seat 41 to move. In this embodiment, the first geared motor 44 is a servo motor paired with a reducer.

[0062] Example 2:

[0063] Based on Example 1, see Figure 4 The injection mechanism 50 includes an ultrapure water injection device 51, an antifreeze injection device 52, an ultrapure water tank 54, and an antifreeze tank 55. The ultrapure water injection device 51 and the antifreeze injection device 52 have the same structure. The ultrapure water injection device 51 includes a first telescopic device 511, with the telescopic end of the first telescopic device 511 facing downwards. An injection seat 512 is installed on the telescopic end of the first telescopic device 511. An inlet pipe 513 is provided on the side wall of the injection seat 512, and an injection pipe 514 is provided at the lower end of the injection seat 512. A first water pump 541 is installed on the ultrapure water tank 54. The inlet of the water pump 541 extends into the ultrapure water tank 54, and the outlet of the first water pump 541 is connected to the inlet 513 of the ultrapure water injection device 51 via a hose; a second water pump 551 is installed on the antifreeze tank 55, the inlet of the second water pump 551 extends into the antifreeze tank 55, and the outlet of the second water pump 551 is connected to the inlet 513 of the antifreeze injection device 52 via a hose; a first connecting plate 56 is installed at the lower end of the fixed ends of the two first telescopic devices 511, and a first visual recognition camera 53 is installed on the lower side of the first connecting plate 56.

[0064] The injection mechanism 50 extends via the first telescopic device 511, thereby inserting the injection port 514 into the packaging barrel 1. The first telescopic device 511 can be a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. The ultrapure water injection device 51 is used to inject ultrapure water into the packaging barrel 1, and the antifreeze injection device 52 is used to inject antifreeze into the packaging barrel 1. The first visual recognition camera 53 is used to detect the position of the two barrel openings at the top of the packaging barrel 1, so that the position of the injection mechanism 50 can be adjusted by the moving unit 40 to align the injection port 514 with the barrel opening at the top of the packaging barrel 1.

[0065] Of course, a rotating structure identical to the airtightness detection mechanism 60 can be installed on the top of the ultrapure water injection device 51 and the antifreeze injection device 52, so as to adapt to the position change of the barrel opening after the packaging barrel 1 rotates in the circumferential direction.

[0067] Based on Example 1 or 2, the air tightness testing mechanism 60 and the hydraulic testing mechanism 70 have the same structure, but the air pressure injected into the air tightness testing mechanism 60 and the hydraulic testing mechanism 70 are different during use.

[0068] Specifically, see Figure 6 The airtightness testing mechanism 60 includes a compressed air injection device 61 and a pressure monitoring device 62. Both the compressed air injection device 61 and the pressure monitoring device 62 include a second telescopic device 611. The telescopic end of the second telescopic device 611 faces downward, and an air guide seat 612 is installed on the telescopic end of the second telescopic device 611. A connection port 613 is provided on the side wall of the air guide seat 612, and an air injection pipe 614 is provided at the lower end of the air guide seat 612. A conical sealing ring 615, which is larger at the top and smaller at the bottom, is fitted on the air injection pipe 614. The connection port 613 of the compressed air injection device 61 is connected to a solenoid valve 617 through an air pipe 616. In use, the solenoid valve 617 is connected to a compressed air source. A pressure gauge or pressure transmitter 621 is installed on the connection port 613 of the pressure monitoring device 62. A second connecting plate 63 is installed at the lower end of the fixed end of the second telescopic device 611 of the compressed air injection device 61 and the pressure monitoring device 62. A second visual recognition camera 64 is installed on the lower side of the second connecting plate 63.

[0069] The second telescopic device 611 extends to insert the air injection pipe 614 into the top opening of the packaging drum 1. The conical sealing ring 615, made of silicone or rubber, seals the air injection pipe 614 with the opening of the packaging drum 1. When the solenoid valve 617 is opened, pressurized air is injected into the air guide seat 612 of the compressed air injection device 61. The pressurized air enters the packaging drum 1 through the air injection pipe 614. The conical sealing ring 615 of the pressure monitoring device 62 blocks the other opening of the packaging drum 1. The pressure inside the packaging drum 1 is detected by a pressure gauge or pressure transmitter 621 installed on the connection port 613. When the preset pressure is reached and the pressure is constant, the pressure data of the pressure gauge or pressure transmitter 621 is observed to determine the airtightness of the packaging drum 1. The second visual recognition camera 64 is used to identify the position of the opening of the packaging drum 1 so that the position of the airtightness detection mechanism 60 can be adjusted by the moving unit 40 to align the air injection pipe 614 with the top opening of the packaging drum 1.

[0070] Further, see also Figure 6 The airtightness testing mechanism 60 and the hydraulic testing mechanism 70 are respectively installed on the lower side of the rotating plate 471. The rotating plate 471 and the moving unit 40 are rotatably connected by a first bearing 49. The upper end of the inner ring 491 of the first bearing 49 is fixed to the moving unit 40, and the lower end of the outer ring 492 of the first bearing 49 is fixed to the rotating plate 471. A first external gear ring 493 is installed on the outer ring 492 of the first bearing 49. A second reduction motor 48 is installed on the moving unit 40, and a second gear 481 is installed on the output shaft of the second reduction motor 48. The second gear 481 meshes with the first external gear ring 493. Through the above structure, the compressed air injection device 61 and the pressure monitoring device 62 can rotate, thereby adapting to the position change of the barrel opening after the packaging barrel 1 rotates in the circumferential direction.

[0071] Example 4:

[0072] Based on Example 1, 2, or 3, see [link to example]. Figure 7 The drop test mechanism 80 includes a third telescopic device 810, with the telescopic end of the third telescopic device 810 facing downwards. A swing link 820 is installed on the telescopic end of the third telescopic device 810, and a clamp 830 is installed laterally on the swing link 820. The clamp 830 is used to clamp the packaging barrel 1.

[0073] See Figure 8The swing linkage 820 includes a fixed rod 821 and a swing rod 822. The fixed rod 821 is located at the upper end of the swing rod 822. The fixed rod 821 and the swing rod 822 are respectively provided with a groove 8211 and a protrusion 8221. The protrusion 8221 extends into the groove 8211 and is hinged by a first pivot 823. The fixed rod 821 is also provided with a receiving groove 8213 on the upper side of the groove 8211. The fixed rod 821 is provided with a through hole 8212 at the position corresponding to the receiving groove 8213. A third reduction motor 824 is installed on one side of the fixed rod 821. The output shaft of the third reduction motor 824 extends into the through hole 8212. A third gear 8241 is installed on the output shaft of the third reduction motor 824. The third gear 8241 is located in the receiving groove 8213. The upper end of the protrusion 8221 is provided with an arc-shaped tooth 8222. The third gear 8241 meshes with the arc-shaped tooth 8222. When the third telescopic device 810 extends downwards, it moves the clamp 830 down to the middle of the packaging barrel 1, clamping the packaging barrel 1. When the third telescopic device 810 retracts, it lifts the packaging barrel 1 to a certain height. Driven by the third reduction motor 824, the swing linkage 822 swings at an angle, causing the packaging barrel 1 to tilt at an angle, thus allowing the packaging barrel 1 to fall at different angles.

[0074] Further, see Figure 9 The clamp 830 includes two jaws 831. One end of each jaw 831 is hinged to a clamping seat 832 via a second pivot 8321. The clamping seat 832 is fixedly mounted to a swing rod 822. First hinge seats 8322 are fixedly connected to both sides of the clamping seat 832, and second hinge seats 8311 are fixedly connected to the outer sides of each jaw 831. A fourth telescopic device 833 is connected between the first hinge seats 8322 and the second hinge seats 8311 on both sides. When the fourth telescopic device 833 extends, the jaws 831 on both sides close, gripping the packaging barrel 1 tightly. When the fourth telescopic device 833 retracts, the jaws 831 on both sides open.

[0075] The fourth telescopic device 833 can be a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder.

[0076] Further, see Figure 7 The third telescopic device 810 is a hydraulic cylinder, pneumatic cylinder, or electric cylinder. A first movable plate 811 is mounted on the telescopic end of the third telescopic device 810. A first guide rod 813 is fixedly mounted on the first movable plate 811. A first positioning plate 812 is mounted on the lower end of the fixed end of the third telescopic device 810. The first guide rod 813 slides upward through a sliding hole in the first positioning plate 812. This structure prevents the clamp 830 from rotating circumferentially away from a preset angular position.

[0077] Example 5:

[0078] Based on Example 1, 2, 3, or 4, see [link to example]. Figure 10 The stacking test mechanism 90 includes a fifth telescopic device 91 and a weight 93. The fifth telescopic device 91 is installed on the lower side of the moving unit 40, with the telescopic end of the fifth telescopic device 91 facing downwards. A lifting hook 92 is installed on the telescopic end of the fifth telescopic device 91.

[0079] See Figure 11 The weight 93 has a lifting seat 931 on top, and the lifting seat 931 has a cavity 932 inside. One side of the lifting seat 931 is open for the insertion of the lifting hook 92.

[0080] When the fifth telescopic device 91 extends, the lifting hook 92 moves downward. When the moving unit 40 moves towards the side of the weight 93, the lifting hook 92 is inserted into the open side of the lifting seat 931. When the fifth telescopic device 91 is shortened, the weight 93 is lifted. Then the moving unit 40 moves the load stacking test mechanism 90 and the weight 93 above the packaging barrel 1. The fifth telescopic device 91 extends one distance to place the weight 93 on the packaging barrel 1. Then the moving unit 40 retracts one distance, and the lifting hook 92 leaves the lifting seat 931.

[0081] Furthermore, the fifth telescopic device 91 is a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder. A second movable plate 911 is installed at the telescopic end of the fifth telescopic device 91, and a second guide rod 913 is fixedly installed on the second movable plate 911. A second positioning plate 912 is installed at the lower end of the fixed end of the fifth telescopic device 91, and the second guide rod 913 slides upward through a sliding hole in the second positioning plate 912. This structure prevents the hook 92 from rotating circumferentially and deviating from a preset angular position.

[0082] Example 6:

[0083] Based on Example 1, 2, 3, 4, or 5, see [link to example]. Figure 12 The rotary conveyor weighing platform 110 includes a base 111. Weighing sensors 112 are installed on the four corners of the base 111. Support columns 113 are installed on the weighing sensors 112. Support plates 114 are installed on the top of the four support columns 113. A conveyor 119 is installed on the top of the support plate 114 through a second bearing 115. The inner circle of the second bearing 115 is fixed to the support plate 114, and the outer ring of the second bearing 115 is fixed to the bottom of the conveyor 119. A second external gear ring 116 is installed on the outer ring of the second bearing 115. A fourth reduction motor 117 is installed on the support plate 114. A fourth gear 118 is installed on the output shaft of the fourth reduction motor 117. The fourth gear 118 meshes with the second external gear ring 116.

[0084] The fourth geared motor 117 drives the fourth gear 118 to rotate, thereby causing the outer ring of the second bearing 115 to rotate. Since the outer ring of the second bearing 115 is fixedly installed at the bottom of the conveyor 119, the conveyor 119 is thus driven to rotate. In use, by driving the entire conveyor 119 to rotate, the conveyor 119 is aligned with the first conveying device 120 at different positions, thereby transporting the packaging barrel 1 to each detection area. The weighing sensor 112 is used to weigh the packaging barrel 1.

[0085] Conveyor 119 can be a belt conveyor or a roller conveyor.

[0086] Combination Figure 1 When the conveyor 119 on the rotary conveyor weighing platform 110 is aligned with the air tightness testing mechanism 60, the packaging barrel 1 will be transported to the area below the air tightness testing mechanism 60.

[0087] When the conveyor 119 on the rotary conveyor weighing platform 110 is aligned with the hydraulic testing mechanism 70, the packaging barrel 1 will be transported to the bottom of the hydraulic testing mechanism 70.

[0088] When the conveyor 119 on the rotary conveyor weighing platform 110 is aligned with the side of the opening and closing door 11, the packaging barrel 1 will be transported to the first conveyor device 120 between the drop test mechanism 80 and the stacking test mechanism 90.

[0089] When the packaging barrel 1 is located on the rotary conveyor weighing platform 110, the packaging barrel 1 is located below the liquid injection mechanism 50.

[0090] Example 7:

[0091] Based on Example 1, 2, 3, 4, 5, or 6, see [link to example]. Figure 3 The test chamber 10 is equipped with a low-temperature compartment 14 and a high-temperature compartment 15. A refrigeration unit 12 is used to cool the low-temperature compartment 14, and a heating unit 16 is used to heat the high-temperature compartment 15. A connecting track unit 20 is provided on the top of the low-temperature compartment 14 and the high-temperature compartment 15. A stacking test mechanism 90 is located in the high-temperature compartment 15, and a drop test mechanism 80 can move between the low-temperature compartment 14 and the high-temperature compartment 15. A first conveying device 120 is provided between the low-temperature compartment 14 and the high-temperature compartment 15. Opening and closing doors are provided opposite to each other in the low-temperature compartment 14 and the high-temperature compartment 15. Through this structure, the space of the heating and cooling areas within the test chamber 10 can be reduced, thereby reducing the energy consumption and effectiveness of the refrigeration unit 12 and the heating unit 16.

[0092] The refrigeration unit 12 adopts a cold storage refrigeration system, and the heating unit 16 can adopt an electric heater.

[0093] Example 8:

[0094] Based on Example 1 or 2 or 3 or 4 or 5 or 6 or 7, see Figure 1 , 2 It also includes a control system 30, which is electrically connected and controlled with the moving unit 40, the liquid injection mechanism 50, the airtightness testing mechanism 60, the hydraulic testing mechanism 70, the drop testing mechanism 80, the stacking testing mechanism 90, the conveying unit 100, the cooling unit 12, and the heating unit 16 to control the moving unit 40, the liquid injection mechanism 50, the airtightness testing mechanism 60, the hydraulic testing mechanism 70, the drop testing mechanism 80, the stacking testing mechanism 90, the conveying unit 100, the cooling unit 12, and the heating unit 16 to operate according to a specified testing process.

[0095] Example 9:

[0096] Based on embodiments 1, 2, 3, 4, 5, 6, 7, or 8, the present invention also provides a detection method using the above-mentioned packaging barrel detection system, for performing airtightness testing, hydraulic testing, drop testing, and stacking testing on the packaging barrel 1.

[0097] During the airtightness test, the packaging barrel 1 is conveyed to the bottom of the airtightness testing mechanism 60 through the conveying unit 100. The airtightness testing mechanism 60 introduces air pressure of 15~25kPa into the packaging barrel 1 and observes the change of the pressure gauge reading on the airtightness testing mechanism 60 to determine whether the airtightness of the packaging barrel 1 is qualified.

[0098] During the airtightness test, the second telescopic device 611 extends, inserting the air injection pipe 614 into the top opening of the packaging drum 1. The conical sealing ring 615 seals the air injection pipe 614 to the opening of the packaging drum 1. When the solenoid valve 617 opens, pressurized air is injected into the air guide seat 612 of the compressed air injection device 61, and the pressurized air enters the packaging drum 1 through the air injection pipe 614. Meanwhile, the conical sealing ring 615 of the pressure monitoring device 62 blocks the other opening of the packaging drum 1. The pressure inside the packaging drum 1 is detected by a pressure gauge or pressure transmitter 621 installed on the connection port 613. When the preset pressure is reached and the pressure is constant, the pressure data of the pressure gauge or pressure transmitter 621 is observed to determine the airtightness of the packaging drum 1.

[0099] During the hydraulic test, the packaging barrel 1 is conveyed to the rotary conveying weighing platform 110 via the first conveying device 120 of the conveying unit 100. Ultrapure water is injected into the packaging barrel 1 via the liquid injection mechanism 50. When the injected weight reaches the set weight, the packaging barrel 1 is conveyed to the bottom of the hydraulic testing mechanism 70 via the conveying unit 100. Then, the hydraulic testing mechanism 70 introduces air pressure of 150~250kPa into the packaging barrel 1 and observes the change in the pressure gauge reading on the hydraulic testing mechanism 70 to determine whether the hydraulic test of the packaging barrel 1 is qualified.

[0100] During hydraulic testing, the first telescopic device 511 of the pure water injection device 51 extends, inserting the injection port 514 into the packaging barrel 1. Then, ultrapure water is injected into the packaging barrel 1 via the first water pump 541. When the injected weight reaches the set weight, the first water pump 541 stops, and the first telescopic device 511 of the pure water injection device 51 retracts. Afterward, the conveyor 119 on the rotary conveyor weighing platform 110 aligns with one side of the hydraulic testing mechanism 70, and the packaging barrel 1 is transported to the bottom of the hydraulic testing mechanism 70. Then, the second telescopic device 611 of the hydraulic testing mechanism 70 extends, inserting the air injection pipe 614 into the top opening of the packaging barrel 1. The conical sealing ring 615 seals the air injection pipe 614 to the opening of the packaging barrel 1. When the solenoid valve 617 opens, pressurized air is injected into the air guide seat 612 of the compressed air injection device 61, and the pressurized air enters the packaging barrel 1 through the air injection pipe 614. The conical sealing ring 615 of the pressure monitoring device 62 seals the other opening of the packaging barrel 1. The pressure inside the packaging barrel 1 is detected by the pressure gauge or pressure transmitter 621 installed on the connection port 613. When the preset pressure is reached and the pressure is constant, the pressure data and leakage of the pressure gauge or pressure transmitter 621 are observed to determine whether the hydraulic test of the packaging barrel 1 is qualified.

[0101] During the drop test, the packaging drum 1 is conveyed to the rotary conveyor weighing platform 110 via the first conveying device 120 of the conveying unit 100. Antifreeze is injected into the packaging drum 1 via the liquid injection mechanism 50. Once the injected weight reaches the set weight, the drum cap is screwed on, and the packaging drum 1 is then conveyed to the first conveying device 120 between the drop test mechanism 80 and the stacking test mechanism 90 via the conveying unit 100. The drop test mechanism 80 moves to the side of the packaging drum 1 via the moving unit 40, clamps the packaging drum 1, and moves it to the drop test area. The cooling unit 12 lowers the temperature of the drop test area to -15℃ to -20℃. The drop test mechanism 80 clamps the packaging drum 1, lifts it to a certain height, and then opens it. The packaging drum 1 falls freely and impacts the ground. The drop test is judged based on the leakage of the packaging drum 1. During the test, the packaging drum 1 is tilted at an angle by swinging the swing rod 822, allowing the packaging drum 1 to fall at different angles.

[0102] During the stacking test, the packaging drum 1 is conveyed to the rotary conveyor weighing platform 110 via the first conveying device 120 of the conveying unit 100. Ultrapure water is injected into the packaging drum 1 via the liquid injection mechanism 50. Once the injected weight reaches the set weight, the drum cap is screwed on. The packaging drum 1 is then conveyed to the first conveying device 120 between the drop test mechanism 80 and the stacking test mechanism 90 via the conveying unit 100. The drop test mechanism 80 moves to the side of the packaging drum 1 via the moving unit 40, and then clamps the packaging drum 1 on the first conveying device 120 and moves it to the stacking test area. The heating unit 16 raises the temperature of the stacking test area to 35℃~45℃. Then, the stacking test mechanism 90 places the weight 93 on top of the packaging drum 1 and maintains it for 15~35 days. The stacking test is judged to be qualified based on the deformation and leakage of the packaging drum 1.
